Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a casting template for building construction. Background Technology

[0002] Formwork used in building construction is a temporary structure used to support uncured concrete, maintaining its designed shape until it hardens. Existing formwork is usually precast or made by overlapping panels (wooden boards or other materials). Precast formwork can typically only produce building modules of a specific shape; while overlapping formwork requires multiple fasteners to secure the panels, making the overlapping and disassembly process cumbersome and time-consuming. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a casting template for building construction, which addresses the above-mentioned shortcomings. The template units of this application can be spliced ​​at a certain angle, and the connecting units can be adjusted according to the splicing angle to connect adjacent template units, thereby improving construction efficiency.

[0004] To solve the above technical problems, the present invention adopts the following technical solution:

[0005] A casting formwork for building construction includes multiple formwork units, which can be spliced ​​and combined to enclose and form a casting formwork with an internal casting space.

[0006] Two adjacent template units can be spliced ​​together at a preset angle, the preset angle being in the range of 60° to 180°. Several connecting units are hinged to the outer wall of the template unit. The connecting units are distributed along the circumference of the template unit and can be connected to the connecting units on adjacent template units.

[0007] Furthermore, the template unit includes a plate body, a frame, and reinforcing ribs. The frame and reinforcing ribs are both disposed on the outer wall of the plate body. The frame is arranged along the edge of the plate body, and the reinforcing ribs are disposed inside the frame.

[0008] Furthermore, the connecting unit includes a hinge seat, a rotating arm, and a cylindrical body. The hinge seat is disposed on the inner side of the frame, one end of the rotating arm is hinged to the hinge seat, and the cylindrical body is disposed at the other end of the rotating arm.

[0009] Furthermore, the hinge seat has a slot located on the side of the rotating arm near the plate, and the rotating arm can be engaged in the slot.

[0010] Furthermore, the connecting units are connected by screws and nuts.

[0011] Furthermore, the range of the preset included angle is 90° to 180°.

[0012] Furthermore, when the preset included angle between the two template units is less than 180°, a filler is provided between the two template units.

[0013] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0014] The template units of this utility model can be spliced ​​at a certain angle, and can be used to build a casting template of a certain shape as needed. The connecting units can rotate according to the included angle between adjacent template units, which facilitates the connection of template units. Compared with the existing casting templates built by using plates, its fixing method is faster and the construction efficiency is higher.

[0024] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0025] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "clockwise" and "counterclockwise" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] A casting formwork for building construction includes multiple formwork units 1, which can be spliced ​​and combined to enclose and form a casting formwork with an internal casting space. Figure 1 As described above, multiple template units 1 are spliced ​​together to form a rectangular casting template, the internal space of which can be used to cast a rectangular concrete structure.

[0027] Furthermore, in order to enable the template unit 1 to be assembled into other shapes of casting templates as needed, two adjacent template units 1 of this application can be assembled with a preset included angle α (the preset included angle α refers to the included angle between two adjacent template units 1) to form other shapes of casting templates. The range of the preset included angle α is 60° to 180°, preferably 90° to 180°.

[0028] Several connecting units 2 are hinged on the outer wall of the template unit 1. The connecting units 2 are distributed along the circumference of the template unit 1. The connecting units 2 are used to connect with the connecting units 2 on the adjacent template unit 1. When the adjacent template units 1 are spliced ​​at a preset included angle a, the connecting units 2 can also rotate at the corresponding angle and then be connected by nuts 32 and screws 31.

[0029] like Figure 4 As shown, in this embodiment, the template unit 1 includes a plate 11, a frame 12 and a reinforcing rib 13. The frame 12 and the reinforcing rib 13 are both disposed on the outer wall of the plate 11. The frame 12 is arranged along the edge of the plate 11, and the reinforcing rib 13 is disposed inside the frame 12.

[0030] The connecting unit 2 includes a hinge seat 21, a rotating arm 22 and a cylinder 23. The hinge seat 21 is located on the inner side of the frame 12, one end of the rotating arm 22 is hinged to the hinge seat 21, and the cylinder 23 is located at the other end of the rotating arm 22.

[0031] like Figure 2 and Figure 3As shown, two adjacent template units 1 are spliced ​​together at a 90° angle. The cylinders 23 on the sides where the two template units 1 meet are rotated so that the axes of the two opposing cylinders 23 coincide, so that the screw 31 can pass through the two cylinders 23. The screw 31 and the cylinders 23 are then fixed relative to each other by the nut 32.

[0032] Furthermore, when the included angle α between two adjacent template units 1 is less than 180°, the contact surface of the two adjacent template units 1 is usually the inner side, and a filler 4 is placed in the outer area where the two template units 1 form an included angle, and the filler 4 is restricted in this area by the screw 31 to form a stable structure.

[0033] like Figure 5 As shown, two adjacent template units 1 are spliced ​​at a 180° angle. In this case, there is no gap between the two adjacent template units 1, so there is no need to set the filler 4.

[0034] It should be noted that, under normal circumstances, the filler 4 is a prefabricated component, meaning that the included angle of the filler 4 is fixed. The corresponding filler 4 needs to be manufactured in advance according to the construction drawings. For example, when two adjacent template units 1 are spliced ​​at a 60° included angle, the sharp angle of the filler 4 is 300°.

[0035] In one embodiment, the hinge seat 21 has a slot 211 located on the side of the rotating arm 22 near the plate 11, allowing the rotating arm 22 to engage with the slot 211. Figure 6 As shown, when it is necessary to transport template unit 1, the cylinder 23 and the rotating arm 22 can rotate to the inside of the frame 12 and lock the rotating arm 22 through the slot 211 to facilitate the stacking of template unit 1.

[0036] During construction, a base plate can be placed at the bottom of the casting formwork as needed. The base plate has multiple threaded holes, and the connecting unit 2 on the bottom edge of the formwork unit 1 can be fixed to the base plate with bolts. After multiple formwork units 1 are assembled to form the casting formwork, concrete is poured into the casting space. Once the concrete has solidified, a concrete structure of the corresponding shape will be formed. After the concrete has solidified, the formwork unit can be disassembled by removing the bolts and nuts on the connecting unit 2.

[0037] The above description provides examples of the preferred embodiments of this utility model. Any aspects not detailed herein are common knowledge to those skilled in the art. The scope of protection of this utility model is determined by the claims. Any equivalent modifications based on the technical teachings of this utility model are also within the scope of protection of this utility model.
