Description

Technical Field

[0001] This utility model relates to a crack-prevention structure for large-area concrete floor construction. Background Technology

[0002] In large-scale construction projects, especially large-span structures, the construction quality and stability of concrete floors are crucial. Therefore, the skip-pour method is often used to actively control structural cracks. By planning in sections and constructing in sections, the early deformation stress of the concrete is released. Then, comprehensive measures are taken to improve the tensile strength of the concrete to resist the residual stress, effectively reducing cracks in ultra-long, ultra-thick, and ultra-thin large-volume concrete, thereby improving project quality. In the pouring of a single section, quick-closing steel mesh is usually used as a non-removable formwork to seal the section and prevent concrete from flowing out during pouring. The quick-closing steel mesh is fixed to the steel reinforcement frame by binding or welding. For larger sections, the number of binding or welding points will increase accordingly, and there will inevitably be places where the fixation is not firm. Therefore, the quick-closing steel mesh is prone to displacement or deformation under the pressure of concrete in these places. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a crack-resistant structure for large-area concrete floor construction. This structure reduces the pressure of concrete on the quick-closing steel mesh by installing a dense wire mesh inside the slab, and reinforces the fixed position of the quick-closing steel mesh by installing diagonal bracing components outside the slab.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a crack-resistant structure for large-area concrete floor construction, comprising a steel reinforcement skeleton, several frame columns, and a quick-closing steel mesh. The quick-closing steel mesh surrounds and is tied to the steel reinforcement skeleton along its circumference. It also includes a dense-hole steel wire mesh that surrounds and is tied to the frame columns, and a diagonal bracing assembly that supports the outside of the quick-closing steel mesh.

[0005] As a further improvement of this utility model, the diagonal bracing assembly includes a clamp installed on the steel reinforcement skeleton of the adjacent compartment and an adjusting rod set on the clamp. The end of the adjusting rod is provided with an abutment rod that is threadedly connected to it. The abutment rod is pressed against the quick-closing steel mesh by adjusting the thread.

[0006] As a further improvement of this utility model, the clamp is provided with a rotating seat, the adjusting rod is rotatably connected to the rotating seat, and the clamp is provided with an abutment component that applies pressure to the adjusting rod.

[0007] As a further improvement of this utility model, the abutting assembly includes a threaded sleeve mounted on the clamp and facing the abutting rod, and a screw rod mounted inside the threaded sleeve, wherein the end of the screw rod used to abut the adjusting rod is ball-shaped.

[0008] As a further improvement of this utility model, the bottom of the quick-closing steel mesh installation is provided with a slot for embedding.

[0009] The beneficial effects of this utility model are as follows: by setting up a dense wire mesh inside the silo to reduce the pressure of concrete on the quick-closing steel mesh, and by setting up diagonal bracing components outside the silo to reinforce the fixed position of the quick-closing steel mesh, the quick-closing steel mesh can be reliably supported, preventing displacement or deformation.

[0014] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0015] Reference Figure 1-3 As shown, a crack-resistant structure for large-area concrete floor construction includes a steel reinforcement frame 1, several frame columns 2, and a quick-closing steel mesh 3. The quick-closing steel mesh 3 surrounds and is fixed to the steel reinforcement frame 1 circumferentially. It also includes a dense-mesh wire mesh 4 surrounding and fixing the frame columns 2, and diagonal bracing components supporting the quick-closing steel mesh 3 externally. The bottom of the quick-closing steel mesh 3 has a slot for embedding; by setting the slot at the bottom of the quick-closing steel mesh 3, the quick-closing effect can be further improved. The installation position of the steel mesh 3 further improves the installation strength of the quick-closing steel plate. The quick-closing steel mesh 3 is set on the outside of the reinforcing steel skeleton 1 to prevent concrete from flowing out. The dense wire mesh 4 surrounding the frame column 2 can buffer the pressure of concrete on the quick-closing steel mesh 3 during pouring. In order to ensure that the binding of the quick-closing steel mesh 3 can be reliably fixed, a diagonal bracing component is set to abut against it. This technical solution reduces the buffer pressure from the inside and provides external support and reinforcement to reduce the displacement or deformation of the quick-closing steel mesh 3.

[0016] The diagonal bracing assembly includes clamps 5 installed on the steel reinforcement skeleton 1 of the adjacent compartment and adjusting rods 6 set on the clamps 5. The end of the adjusting rod 6 is provided with abutment rod 7 threadedly connected to it. The abutment rod 7 is pressed onto the quick-closing steel mesh 3 by adjusting the thread. The diagonal bracing assembly provides additional support for the quick-closing steel mesh 3, which can improve its deformation or displacement during concrete pouring, thereby ensuring the flatness and overall stability of the concrete after pouring.

[0017] The clamp 5 is provided with a rotating seat 8, and the adjusting rod 6 is rotatably connected to the rotating seat 8. The clamp 5 is provided with an abutment component that applies pressure to the adjusting rod 6. The abutment component includes a threaded sleeve 9 installed on the clamp 5 and facing the abutment rod 7, and a screw 10 installed in the threaded sleeve 9. The end of the screw 10 used to abut the adjusting rod 6 is ball-shaped. Rotating the adjusting rod 6 on the clamp 5 can better match the steel reinforcement skeleton 1 with different structures, and adjusting the angle can better abut against the quick-closing steel mesh 3. The abutment component is set so that the adjusting rod 6 can continuously and reliably abut against the quick-closing steel mesh 3 during the support process.

[0018] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
