Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a hollow mold box with a built-in anchoring device. Background Technology

[0002] In the construction process, for the construction of large open spaces, such as large open-plan buildings and large conference rooms, hollow formwork is often used to create large column-free spaces, which improves the efficiency and flexibility of space utilization, since these large spaces usually do not have load-bearing columns.

[0003] In actual construction, traditional methods typically employ two approaches. The first is the steel reinforcement method, which involves placing horizontal steel bars at the top of the hollow formwork box. These bars are then connected to the structural steel bars to fix the formwork box in its designed position, preventing displacement and floating. However, since the steel bars are purchased externally, their cost is high, and a significant amount of manpower is required to secure them. Therefore, the use of steel bars increases both material and labor costs, hindering cost control. The second method is the wire binding method, which uses wire to bind the formwork box to the template or structural steel bars. However, this requires the wire to pass through pre-drilled holes. The process of tying the holes to the formwork or reinforcing bars below increases labor costs and workload. After the concrete is poured, some of the tying wires will be exposed, affecting the aesthetics. Removing these wires requires considerable cost and time, impacting the construction progress and resulting in a large workload. Furthermore, the strength of the tying depends on the tightness of the tying process. If the tying is not tight, it will increase the risk of the formwork floating. If the formwork floats, it will change the structural stress of the floor slab, affecting the flatness of the floor slab, which may lead to cracks, deformation, or even damage to the floor slab, reducing the load-bearing capacity of the floor slab and affecting the safety and practicality of the building.

[0023] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] like Figures 1-3 The hollow mold box shown includes an anchoring device and a box body 4. The anchoring device includes a first lead screw 1, a second lead screw 2, and a connecting nut 3. The first lead screw 1 is mounted on the box body 4 and is connected to the connecting nut 3. The second lead screw 2 is also connected to the connecting nut 3. The box body 4 is provided with cross reinforcing ribs 5 and top reinforcing ribs 6. The end of the first lead screw 1 away from the connecting nut 3 is connected to the top reinforcing rib 6. The cross reinforcing ribs 5 are connected to the first lead screw 1. The second lead screw 2 is also provided with a mountain-shaped clip 7.

[0028] The hollow formwork box with built-in anchoring device mentioned above, by setting cross reinforcing ribs 5 and top reinforcing ribs 6 inside the box body 4 and connecting them to the first threaded rod 1, not only enhances the structural stability of the box body 4, but also limits the position of the first threaded rod 1. At the same time, the first threaded rod 1 is set on the box body 4 to prevent the structure of the box body 4 from being damaged by buoyancy during the concrete pouring process. The mountain-shaped clip 7 set on the second threaded rod 2 will fix the first threaded rod 1 to the floor formwork through the connecting nut 3, effectively preventing the formwork box from floating.

[0029] like Figures 1-3 As shown, in this embodiment, the connecting nut 3 is shaped like a frustum. The connecting nut 3 has a structure design with one end larger than the other, but its internal thread size is the same. Therefore, the connecting nut 3 can be connected to the first lead screw 1 and the second lead screw 2 at the same time. Since it is necessary to connect two lead screws, the frustum-shaped connecting nut 3 can increase the connection area with the lead screws compared to ordinary nuts, thereby improving the stability of the connection. At the same time, after the pouring construction is completed, the connecting nut 3 and the second lead screw 2 can be removed from the first lead screw 1 and reused, which saves costs and reduces the use of parts. Moreover, the use of threaded connection is also relatively simple to operate, effectively reducing labor costs. There is also no need to remove the exposed steel wire after the steel wire is tied, which will affect the appearance. This saves costs and time and will not affect the construction progress.

[0030] like Figures 1-3 As shown, in this embodiment, the length of the box 4 is 800mm; the width of the box 4 is 800mm; the height of the box 4 is 600mm; the dimensions of the box 4 are determined according to the requirements of the actual construction process. Therefore, the dimensions of the box 4 can be modified and adjusted according to actual needs. At the same time, the first lead screw 1 is set on the box 4, and the two are connected by threads. There will be no leakage during the concrete pouring process, which ensures the airtightness of the connection.

[0031] like Figures 1-3 As shown, in this embodiment, the cross-sectional diameter of the first lead screw 1 is 12mm; the cross-sectional diameter of the second lead screw 2 is 12mm; the length of the second lead screw 2 is 400mm; the cross-sectional diameters of the first lead screw 1 and the second lead screw 2 are the same, and the cross-sectional diameters of the first lead screw 1 and the second lead screw 2 can also be 14mm, and the cross-sectional diameters of the first lead screw 1 and the second lead screw 2 can be adjusted according to different construction requirements.

[0032] like Figures 1-3As shown, in this embodiment, the cross reinforcing rib 5 is connected to the box body 4 by welding; the top reinforcing rib 6 is connected to the box body 4 by welding; the cross reinforcing rib 5 is arranged crosswise inside the box body 4. During construction, the cross reinforcing rib 5 is first wound around the first threaded rod 1 to achieve a fixed connection, and then the cross reinforcing rib 5 is welded to the box body 4. Similarly, the top reinforcing rib 6 is first welded to the first threaded rod 1, and then the top reinforcing rib 6 is welded to the box body 4. In addition, the number of reinforcing ribs can be increased inside the box body 4 according to the actual situation to improve the stability of the box body 4 structure and further fix the position of the first threaded rod 1, ensuring construction quality. Welding can also increase the connection strength and ensure the stability of the mold box structure.

[0033] like Figure 3 As shown in this embodiment, during actual construction, after the template support system and floor slab template are installed, the hollow formwork can be placed according to the design drawings. The first threaded rod 1, the connecting nut 3, and the second threaded rod 2 are connected in sequence, and the second threaded rod 2 passes through the wooden template 8 and the wooden beam 9 in sequence. Steel pipes 10 are also set in pairs below the wooden beam 9. The steel pipes 10 can be better matched and connected with the mountain-shaped clips 7. Rotate the mountain-shaped clips 7 on the second threaded rod 2 until the mountain-shaped clips 7 abut against the steel pipes 10. The steel pipes 10 serve as a reinforcement system, and the mountain-shaped clips 7 fix the steel pipes 10 to ensure that the hollow formwork does not float or shift, thus completing the reinforcement installation of the hollow formwork.

[0034] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
