All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
An embodiment of a scaffold for construction of the present invention is shown in fig. 1 to 10.
The scaffold for building construction comprises a scaffold body 100 and a plurality of supporting mechanisms 200, wherein the scaffold body 100 comprises a plurality of upright posts 110, the supporting mechanisms 200 are arranged in one-to-one correspondence with the upright posts 110, and each supporting mechanism 200 is arranged on one upright post 110 which is arranged in a corresponding manner.
The support mechanism 200 includes a leg 210, a roller 220, a support belt 230, and a support arm 240. The legs 210 are movably mounted on the corresponding columns 110 along a first direction, which is a vertical direction. The roller 220 is rotatably mounted on the leg 210 around a second direction, which is perpendicular to the first direction, and the roller 220 is capable of rolling along the ground 600. The support arm 240 is rotatably mounted on the leg 210 around the second direction, the support belt 230 is wound on the roller 220, the support belt 230 can be clamped on the support arm 240, and when the support belt 230 is clamped on the support arm 240, the support belt 230 can be in contact with the ground 600.
Specifically, the columns 110 and the supporting mechanism 200 are each provided in four. The support legs 210 are provided with mounting frames 211, and the rollers 220 are rotatably mounted on the mounting frames 211.
In this embodiment, the supporting mechanisms 200 are respectively disposed on the plurality of upright posts 110, and before the scaffold body 100 is pulled by an operator, the rollers 220 on the supporting mechanisms 200 rotate around the second direction along the ground 600, so that the whole scaffold can be moved, and the scaffold can be moved to a designated position.
When the scaffold is moved to the designated position, if there is an inclination of the ground 600, the operator first adjusts the support mechanism 200 at the lower position so that the corresponding leg 210 on the support mechanism 200 at the lower position moves in the first direction into contact with the ground 600. Then, the operator pulls the supporting belt 230 manually, pulls the supporting belt 230 out of the roller 220, and clamps the supporting belt 230 on the supporting arm 240, at this time, the supporting belt 230 contacts the ground 600 and completes the adjustment of one supporting mechanism 200, and then the operator can adjust the supporting mechanisms 200 according to the actual situation of the ground 600.
After all adjustment of the plurality of support mechanisms 200 and the ground 600 is completed, a stable triangle structure is formed among the support leg 210, the support belt 230 and the support arm 240 of each support mechanism 200, and the support belts 230 of the plurality of support mechanisms 200 can be adapted according to the inclination condition of the ground 600 where the support belts are located, so that each support belt 230 is in surface contact with the ground 600 correspondingly arranged, and the pulled support belt 230 can also play a role in limiting the rotation of the roller 220 around the second direction after being clamped on the support arm 240, thereby avoiding unstable support caused by the rolling of the roller 220 on the ground 600 and improving the overall stability of the scaffold.
In this embodiment, the supporting belt 230 is made of rubber.
Further, a plurality of protrusions are uniformly distributed on the surface of the support belt 230 facing the ground 600. Or the support bands 230 may be configured to be thin at both ends and thick in the middle.
In this embodiment, the supporting belt 230 is made of rubber, so that the friction between the supporting belt 230 and the ground 600 can be increased, and the stability of the support between the supporting belt 230 and the ground 600 can be improved. By further uniformly distributing a plurality of protrusions on the surface of the support belt 230 facing the ground 600, or by arranging the support belt 230 to be thin at both ends and thick in the middle, the gripping force between the support belt 230 and the ground 600 can be further increased when the support belt 230 is pulled out from the roller 220, thereby further improving the stability of the support.
In the present embodiment, the supporting belt 230 is mounted in the roller 220 by a first elastic member, which always has a tendency to urge the supporting belt 230 to rotate around the second direction, and which is a coil spring.
Specifically, the roller 220 is provided with a first clamping groove, one end of the supporting belt 230 is provided with a clamping rod 231, and the clamping rod 231 is clamped on the first clamping groove in an initial state. The supporting arm 240 is provided with a second clamping groove 241, and the clamping rod 231 can be clamped on the second clamping groove 241.
The first elastic piece, the first clamping groove and the second clamping groove 241 are matched. When the supporting belt 230 is pulled out from the first clamping groove, the other end of the clamping rod 231 can be clamped on the second clamping groove 241, and the first elastic member is wound to store force.
In the present embodiment, two connection posts 212 are provided on the leg 210, and the two connection posts 212 are symmetrically provided with respect to a central axis of the leg 210 in the first direction. The support arm 240 is rotatably mounted to the two connection posts 212 about a second direction. The dimension of the connection post 212 to the ground 600 in the first direction is equal to the dimension of the support arm 240, and the support arm 240 is positioned at a side of the roller 220 away from the ground 600 in the first direction in the initial state.
Specifically, the support arm 240 includes a support plate 242 and two rotating arms 243, each rotating arm 243 is disposed corresponding to one connecting post 212, one end of each rotating arm 243 is rotatably matched with the corresponding connecting post 212, and the other end of the rotating arm 243 is rotatably matched with the support plate 242. The second clamping groove 241 is formed on the supporting plate 242.
By providing the support arm 240 composed of the support plate 242 and the two rotating arms 243, the support plate 242 can be prevented from contacting the ground 600 in the initial state, so that both the support plate 242 and the two rotating arms 243 overlap the support leg 210 in the initial state, and when the operator rotates the two rotating arms 243 relative to the support leg 210 and rotates the support plate 242 relative to the two rotating arms 243 until the support plate 242 can abut the ground 600, the rotation of the support plate 242 and the two arms is stopped.
For convenience of description, when the overall inclination of the ground 600 is uniform, the operator can position the support arm 240 on the side of the roller 220 having a higher inclination with respect to the ground 600, and the plurality of support arms 240 are oriented on the same side, and because the dimension of the connecting post 212 from the ground 600 in the first direction is equal to the dimension of the support arm 240, when the support plate 242 is abutted against the ground 600, the greater the angle between the plane formed by the contact point of the support plate 242 with the ground 600 and the origin and the horizontal plane 700, that is, the greater the angle between the plane formed by the support belt 230 and the horizontal plane 700, the longer the length of the support belt 230 is pulled out, and the greater the contact area of the support belt 230 with the ground 600, the higher the stability of the scaffold overall. And if the roller 220 has a tendency to continue rolling, the resistance of the support belt 230 and the support arm 240 also limits the rolling of the roller 220.
Referring to fig. 10, the connecting post 212 and the supporting arm 240 have the same length, and when the ground 600 is inclined to a different degree relative to the horizontal plane 700, the angle between the ground 600 (referred to as the ground 600 one) and the horizontal plane 700, where the dotted line is located, is smaller than the angle between the ground 600 (referred to as the ground 600 two) and the horizontal plane 700, where the solid line is located.
For installation of the first ground 600, in use, the support arm 240 is rotated to bring the support arm 240 into abutment with the first ground 600 and the support strap 230 is pulled out of the connection post 212, and as the first ground 600 is tilted, the support strap 230 is suspended from the support arm 240 (intersection O2) along the first ground 600, i.e., the connection post 212, the support strap 230 and the support arm 240 form an isosceles triangle. Similarly, with respect to the second ground 600, since the ground 600 is inclined to the horizontal plane 700 to a greater extent than the first ground 600, the length of the support belt 230 pulled out is longer (the intersection O1). That is, the longer the support band 230 is pulled out, the larger the contact area of the support band 230 with the ground 600.
Or the roller 220 is provided with a brake pad. The operator can adopt the mode of further manual brake, avoids the gyro wheel 220 to roll in the use, guarantees the steady use of scaffold frame.
That is, the contact area of the support belt 230 and the ground 600 is positively correlated with the inclination degree of the ground 600, and the contact area of the support belt 230 and the ground 600 can be adaptively adjusted according to the ground 600 with different inclination degrees in this embodiment, so that the overall stability of the scaffold is improved.

When the scaffold moves to the designated position, if the ground 600 is inclined, the operator adjusts the supporting mechanism 200 at the lower position, at this time, the operator can manually operate the tail ends of the two threaded sleeves 500 to separate the spiral protrusions from the spiral grooves, and the limiting columns 320 and the matching columns 540 slide in the waist-shaped grooves 510, then the inserting blocks 530 are loosened, the second elastic piece 560 is reset, and at this time, the two locking columns 550 are driven by the second elastic piece 560 to move into the space defined by the two threaded sleeves 500 after being separated from each other.
The operator may then manually pull the leg 210 to move the leg 210 in a first direction relative to the two threaded sleeves 500 to provide coarse adjustment of the leg 210.
After the rough adjustment is completed, the insert 530 is pulled in the first direction toward a side away from the rotating ring 300 again, so that the insert 530 drives the locking post 550 to move, and the second elastic member 560 is stretched. The operator can then manually move the trailing ends of the two threaded sleeves 500 toward each other, thereby re-engaging the helical projection and the helical groove to reset the two threaded sleeves 500 and the locking assembly 520.
Then, the hand lever 410 may be rotated, and the rotation of the hand lever 410 drives the worm 400 to rotate, so that the worm 400 and the worm groove cooperate to drive the rotating ring 300 to rotate around the first direction, and the rotating ring 300 rotates around the first direction to drive the insert block 530, the two locking assemblies 520 and the two threaded sleeves 500 to synchronously rotate, and drive the support leg 210 in spiral cooperation with the rotating ring 300 to move in the first direction, so as to fine-adjust the position of the support leg 210 in the first direction.
By combining coarse adjustment and fine adjustment, the precision of scaffold adjustment can be improved, and then an operator manually pulls the support belt 230 to pull the support belt 230 out of the roller 220 and clamp the support belt 230 onto the support arm 240, at this time, the support belt 230 contacts the ground 600 and completes adjustment of a support mechanism 200.
The operator can adjust the plurality of support mechanisms 200 according to the actual situation of the ground 600. After all adjustment of the supporting mechanisms 200 and the ground 600 is completed, a stable triangle structure is formed among the supporting leg 210, the supporting belt 230 and the supporting arm 240 of each supporting mechanism 200, and the supporting belts 230 of the supporting mechanisms 200 can be adapted according to the inclination of the supporting points where the supporting belts are located, so that each supporting belt 230 is in surface contact with the supporting points corresponding to the supporting belts, and the pulled supporting belt 230 can also play a role in limiting the roller 220 to rotate around the second direction after being clamped on the supporting arm 240, so that the unstable supporting frame caused by the rolling of the roller 220 on the ground 600 is avoided, and the overall stability of the scaffold is improved.
