Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a top support device for controlling cracks in ultra-long reinforced concrete structures. Background Technology

[0002] Reinforced concrete structures are concrete structures that require steel reinforcement during construction. In some construction processes, the length of reinforced concrete structures is relatively large, and it is necessary to support the structure during construction to prevent or control cracks. Therefore, an appropriate number of support devices should be selected according to the situation.

[0003] In the process of realizing this utility model, the inventors discovered that the following problems in the prior art have not been solved: Although the existing top support device for cracks in reinforced concrete structures has a good top support function, the device is large in size, resulting in high transportation and storage costs in the later stage. Moreover, it is not conducive to short-distance manual transportation and loading at the end of the work. Therefore, we propose a top support device for controlling cracks in ultra-long reinforced concrete structures. Utility Model Content

[0004] The purpose of this invention is to provide a top support device for controlling cracks in ultra-long reinforced concrete structures, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a top support device for controlling cracks in ultra-long reinforced concrete structures, comprising a base, wherein support blocks are placed at the four corners of the bottom of the base, and a top support plate is placed on the top of the base;

[0006] The base has slots at all four corners on its lower surface and threaded grooves on the inner side of its upper surface near the slots.

[0007] The lower surface of the top support plate is provided with a receiving groove, and a support rod is placed at each of the four corners of the receiving groove. The top end of the support rod is rotatably connected to the top support plate through a hinge. A protrusion is fixedly installed at the bottom end of the support rod, and a rubber layer is fixedly installed at the top of the top support plate.

[0008] A screw is placed at the bottom of the protrusion, the top end of the screw is rotatably connected to the protrusion through bearing b, and the bottom end of the screw is screwed into the threaded groove through a thread.

[0009] A threaded post is movably inserted through the upper side of the base near the slot. The threaded post is rotatably connected to the base via bearing a. A support block is movably positioned in the slot.

[0010] The support block has a screw hole, and the threaded post is screwed into the screw hole through a thread;

[0011] Both sides of the top support plate and both sides of the base are fixedly installed with ear plates, which can be used in conjunction with components such as screws, receiving grooves and hinges. During the use of the top support device, the support rod can be moved outward and the screw can be rotated to screw the screw into the threaded groove of the base, moving the top support plate to the lower side of the crack. Then, the threaded column can be rotated to move the support block in the slot down until the top support plate abuts against the designated position of the concrete structure. After use, the screw can be removed and the support rod can be rotated to make the support rod and the threaded column located in the receiving groove, and the top support plate fits against the base. This assembly design can reduce the space occupied by the device and facilitate transportation and storage.

[0012] As an optional solution to the technical solution of this application, both sides of one end face of the base are rotatably connected to casters via wheel frames. A handle is fixedly installed on the side of the base facing away from the casters. Bolts are movably inserted into both sets of ear plates. The casters and handles can be used together. Whenever the top support plate is attached to the base, the bolts can be inserted through the ear plates and nuts can be screwed on to temporarily connect and fix the top support plate to the base. Then, the base can be tilted so that the casters contact the ground. At the same time, the handle can be held to pull the device. This structural design facilitates short-distance manual transfer and has a relatively ideal effect.

[0013] As an optional solution to the technical solution of this application, an indicator sign is fixedly installed on the center of the front side of the base, and the indicator sign is fixed by welding. The guide text on the indicator sign can introduce and promote the product, and at the same time, it can be used to introduce assembly safety matters.

[0014] As an optional solution to the technical solution of this application, a hexagonal block is fixedly installed on the side of the screw near the bearing b, and the outer wall of the hexagonal block is opened into a hexagonal surface. Personnel can use a wrench to clamp the hexagonal block, making it convenient for personnel to apply force to rotate the screw.

[0015] As an optional solution to the technical solution of this application, the four sets of support rods are designed to be staggered. By staggering the support rods, the support rods can be rotated inward and retracted, which meets the usage requirements.
