Description

Technical Field

[0001] The utility model relates to the technical field of scaffold adjustment, in particular to an adjustable top support for a scaffold. Background Technique

[0002] With the rapid development of infrastructure construction, during the construction of many projects, it is inevitable to use scaffolds for formwork erection; however, at present, most construction sites are still using traditional scaffold devices. The purpose of using the scaffold top support is to support the I-beam above the scaffold top support, and transfer the force on the I-beam to the threaded pipe below the top support, and then to the scaffold support below. A scaffold is a working platform erected to ensure the smooth progress of each construction process; when the scaffold is erected, multiple groups of pipes and scaffold connectors cooperate to make the scaffold play a stable supporting role; the disc-type scaffold has the advantages of strong high-temperature resistance, non-combustibility, strong bearing capacity, etc. It is widely used in the formwork support of various reinforced concrete buildings during concrete pouring. At the same time, during transportation, the general top support, flat support and adjustable socket are transported separately, but a large amount of installation work of the adjustable socket of the top support and flat support is required during use.

[0003] The existing scaffold top support cannot keep the I-beam in the middle position when supporting the I-beam, resulting in uneven force on the top of the top support, which easily causes the top support to tilt to the side with greater force. Moreover, when the scaffold top support is supporting, the load-bearing mechanism is only the overall top support and the support rod. If used for too long or under too much force, it is easy to damage the overall scaffold and cause safety accidents. In view of this technical problem, the present application proposes an adjustable top support for a scaffold. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to propose an adjustable top support for a scaffold.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An adjustable top support for a scaffold includes a support rod. Both the left and right sides of the top of the support rod are fixedly connected with support blocks. The top sides of the two support blocks are fixedly connected with a top support bottom plate. Two sliding grooves are opened on the top side of the top support bottom plate. Two sliders are slidably connected inside the two sliding grooves. The top sides of the sliders are fixedly connected with top support side plates. Fixing strips are fixedly connected to the adjacent sides of the two sliders at the left and right ends, and a bidirectional screw is threadedly connected to the adjacent sides of the two sliders at the front and rear ends.

[0007] Furthermore, a support base is provided on the bottom side of the top support base plate. At both left and right ends of the bottom side of the support base, limit blocks are fixedly connected. Two support bars are arranged on the outer periphery of the support rod. At the top sides of the two support bars, first limit grooves are opened. The inner wall of the first limit groove is slidably connected to the outer wall of the limit block, and the bottom side of the support base is connected to the two support bars.

[0008] Furthermore, at the separated ends of the top sides of the two support bars, two second limit grooves are opened. At both left and right ends of the support base, fixing frames are arranged. The bottom ends of the two fixing frames are slidably connected to the inner walls of the second limit grooves.

[0009] Furthermore, two I-shaped steels are fixedly connected to the bottom sides of the two support bars. Two sleeves are fixedly connected to the adjacent sides of the two I-shaped steels.

[0010] Furthermore, screw holes are opened at both left and right ends of the two support bars. Two screws are threadedly connected to the inner walls of the two screw holes. Nuts are fixedly connected to the rear sides of the two screw holes. The rear ends of the screws are threadedly connected to the inner walls of the nuts.

[0011] Furthermore, rotating handles are fixedly connected to both left and right ends of the bidirectional screw.

[0012] Furthermore, a spirit level is arranged on the front sides of the two support blocks.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, through the mutual cooperation of the top support base plate, the top support side plate, the sliding groove, the sliding block, the connecting strip, the bidirectional screw, and the rotating handle, the adjustment of the top support position is realized, avoiding the deviation of the I-shaped steel to the side with larger force during use, so as to prevent the deformation of the side with larger force on the top support, and the force on the I-shaped steel cannot be effectively transmitted to the support rod and then to the scaffold, resulting in the damage of the overall integrity of the mechanism.

[0015] 2. In the utility model, through the mutual cooperation of the support base, the limit block, the first limit groove, the fixing frame, the second limit groove, and the support bar, the overall force sharing of the top support structure is realized, avoiding the damage of the overall integrity of the top support structure due to long-term use or excessive gravity, so as to prevent the support rod from breaking, causing safety accidents, resulting in casualties of workers, and endangering the safety of operators.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Refer to Figure 1 and Figure 2 , an embodiment provided by the present utility model: An adjustable top support for a scaffolding includes a support rod 1. Both the left and right sides of the top of the support rod 1 are fixedly connected with support blocks 2. The top sides of the two support blocks 2 are fixedly connected with a top support bottom plate 3. Two chutes 4 are opened on the top side of the top support bottom plate 3. Two slide blocks 5 are slidably connected inside the two chutes 4. The top sides of the slide blocks 5 are fixedly connected with top support side plates 8. Fixed strips 20 are fixedly connected to the adjacent sides of the two slide blocks 5 at the left and right ends, and bidirectional screws 6 are threadedly connected to the adjacent sides of the two slide blocks 5 at the front and rear ends. Adjust the distance between the top support bottom plate 3 and the bracket 12 so that the top support bottom plate 3 contacts the supported object. By rotating the rotating handle 7 to drive the bidirectional screw 6 to rotate, the top support side plates 8 threadedly connected to the outer wall of the bidirectional screw 6 move horizontally towards each other under the limiting action of the slide blocks 5 and the fixed strips 20 connected to their bottom sides, and are adjusted to a suitable position so that the object to be supported is in the center position on the top side of the top support bottom plate 3, ensuring that the overall force of the top support structure is uniform, avoiding the I-beam 11 from shifting to the side with greater force during use, thereby causing deformation on the side of the top support with greater force and being unable to effectively transfer all the force on the I-beam 11 to the support rod 1 and then to the scaffolding, resulting in damage to the overall integrity of the mechanism.

[0024] Refer to Figure 3 andFigure 4 , a support base 12 is provided on the bottom side of the top support base plate 3. At both left and right ends of the bottom side of the support base 12, limiting blocks 13 are fixedly connected. Two support bars 10 are arranged on the outer periphery of the support rod 1. Limiting grooves 14 are opened on the top sides of the two support bars 10. The inner wall of the limiting groove 14 is slidably connected to the outer wall of the limiting block 13. The bottom side of the support base 12 is connected to the two support bars 10. The limiting block 13 fixedly connected to the bottom side of the support base 12 is inserted into the limiting groove 14 opened on the top side of the support bar 10 to form a mortise and tenon connection, which is convenient for disassembly and replacement. At the separated ends of the top sides of the two support bars 10, two limiting grooves 15 are opened. Fixed frames 16 are arranged at both left and right ends of the support base 12. The bottom ends of the two fixed frames 16 are slidably connected to the inner wall of the limiting groove 15. After the limiting block 13 is inserted into the limiting groove 14, it is stabilized by a fixing mechanism formed by inserting the fixed frames 16 in contact with both sides of the support base 12 into the limiting groove 15. The fixed frame 16 limits the moving direction of the support base 12 and the support bar 10 to prevent sliding during use and cause safety accidents. Two I-beams 11 are fixedly connected to the bottom sides of the two support bars 10. Two sleeves 17 are fixedly connected to the adjacent sides of the two I-beams 11. The top side of the support bar 10 is in contact with the top side of the support base 12, and the bottom side of the support bar 10 is in contact with the top side of the I-beam 11. When the entire top support mechanism is under pressure, the force on the top support base plate 3 is shared to prevent a single force-bearing mechanism from damaging the overall structure of the scaffold. At both left and right ends of the two support bars 10, screw holes are opened. Two screws 18 are threadedly connected to the inner walls of the two screw holes. Nuts 19 are fixedly connected to the rear sides of the two screw holes. The rear end of the screw 18 is threadedly connected to the inner wall of the nut 19. When disassembling the entire top support mechanism, the screw 18 is screwed out to loosen the inside of the support base 12, which is convenient for disassembly and improves work efficiency. Rotating handles 7 are fixedly connected to both left and right ends of the bidirectional screw 6. It provides a boosting effect for adjustment, saves time and effort, and improves work efficiency. A spirit level 9 is arranged on the front side of the two support blocks 2. It is convenient to detect the overall levelness of the mechanism in a timely manner.

[0025] Working principle: First, the entire jacking mechanism is installed on the fixing mechanism. Adjust the distance between the jacking bottom plate 3 and the support base 12 so that the jacking bottom plate 3 contacts the supporting object. By rotating the rotating handle 7, the bidirectional screw 6 rotates. Under the limiting action of the slider 5 connected to the bottom side of the jacking side plate 8 threadedly connected to the outer wall of the bidirectional screw 6 and the fixing strip 20, the two jacking side plates 8 move horizontally towards each other and are adjusted to a suitable position so that the object to be supported is in the center position on the top side of the jacking bottom plate 3. After the adjustment is completed, the entire mechanism is reinforced. The limiting block 13 fixedly connected to the bottom side of the support base 12 is inserted into the first limiting groove 14 opened on the top side of the support strip 10 to form a mortise and tenon connection for pre-fixing the entire mechanism. Then, after the limiting block 13 is inserted into the first limiting groove 14, the fixing mechanism formed by the insertion of the fixing frame 16 contacting both sides of the support base 12 into the second limiting groove 15 is used for stabilization. The fixing frame 16 limits the moving direction of the support base 12 and the support strip 10 to achieve final fixation. The top side of the support strip 10 contacts the top side of the support base 12, and the bottom side of the support strip 10 contacts the top side of the I-beam 11. When the entire jacking mechanism is subjected to pressure, the force on the jacking bottom plate 3 is dispersed to avoid a single stressed mechanism and damage to the overall structure of the scaffolding.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
