Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum formwork production, and relates to a formwork structure suitable for the lifting hook of a civil air defense door. Background Technique

[0002] When constructing the basement civil air defense door structure with aluminum formwork, the upper part of the lifting hook of the civil air defense door needs to be fixed to the steel bar structure of the building main body, and its lower part needs to extend out of the structural surface. Therefore, when installing the formwork at this place, it is necessary to reserve an avoidance hole on the formwork so that the bottom of the civil air defense lifting hook can penetrate the formwork at the bottom. Therefore, when processing the aluminum formwork at this place, the following problems will occur:

[0003] 1. Since the size and position of each lifting hook of the civil air defense door are not uniform, it is difficult to produce a shaped aluminum formwork opening plate.

[0004] 2. If the hole is opened on the aluminum formwork on site, the aluminum formwork cannot be recycled, resulting in material waste. Content of the Utility Model

[0005] The purpose of the utility model is to provide a formwork structure suitable for the lifting hook of a civil air defense door to solve the technical problems described in the background technique.

[0006] To achieve the above technical purpose, the utility model adopts the following technical scheme: A formwork structure suitable for the lifting hook of a civil air defense door, characterized in that the formwork structure includes a plurality of aluminum formworks and a plurality of angle aluminums. A frame is provided on one surface of each aluminum formwork, and a plurality of bolt holes are opened on each frame and angle aluminum; a plurality of the aluminum formworks are assembled together by bolts to form a pouring surface, and a rectangular installation hole is reserved in the middle of the pouring surface; Angle aluminums are fixed on the two inner walls opposite to the installation hole by bolts, and a wooden formwork is fixed between the two angle aluminums by screws; The wooden formwork is closely and flush with the adjacent aluminum formwork, and a sealing tape is pasted at each joint of the wooden formwork and the aluminum formwork; An avoidance hole is opened on the wooden formwork.

[0007] Advantages of the utility model:

[0008] 1. In the formwork structure of the utility model, the installation hole can be reserved on site and the avoidance hole can be opened according to the position of the lifting hook of the civil air defense door, making its position more accurate and the operation simpler.

[0009] 2. The formwork structure of the utility model adopts the method of locally inlaying a wooden formwork, making its structure stable and without additional reinforcement.

[0010] 3. Compared with the all-aluminum formwork structure, the price of the wooden formwork in the formwork structure of the utility model is lower. Therefore, even if the waste caused by the inability to continue to circulate after cutting and opening the hole is smaller, the construction cost can be reduced. Description of the Drawings

[0011] Figure 1 It is a three-dimensional schematic diagram of the template structure.

[0012] In the figure, 1 is an aluminum formwork; 2 is an angle aluminum; 3 is a bolt hole; 4 is a mounting hole; 5 is a wooden formwork; 6 is an avoidance hole; 7 is a lifting hook for civil air defense door. Specific embodiments

[0013] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0014] As Figure 1 shown, a formwork structure applicable to the lifting hook of a civil air defense door includes a plurality of aluminum formworks 1 and a plurality of angle aluminums 2. A frame is provided on one surface of each aluminum formwork 1, and a plurality of bolt holes 3 are opened on each frame and the angle aluminum 2; a plurality of the aluminum formworks 1 are assembled together by bolts to form a pouring surface, and a rectangular mounting hole 4 is reserved in the middle of the pouring surface; Angle aluminums 2 are fixed on the two opposite inner walls of the mounting hole 4 by bolts, and a wooden formwork 5 is fixed between the two angle aluminums 2 by screws; the wooden formwork 5 is closely and flush with the adjacent aluminum formwork 1, and sealing tapes are pasted at the joints between the wooden formwork 5 and the aluminum formwork 1; Avoidance holes 6 are opened on the wooden formwork 5.

[0015] The specific construction process of this formwork structure is as follows: First, use the aluminum formwork 1 to assemble the floor formwork, and reserve the mounting hole 4 near the position where the lifting hook 7 of the civil air defense door needs to be set; then, install a special angle aluminum 2 in the mounting hole 4, and the top of the angle aluminum 2 is 15 mm lower than the surrounding aluminum formwork 1 to reserve the installation space for the wooden formwork 5, so that after the wooden formwork 5 is installed, it can be flush with the surrounding aluminum formwork 1; then, cut out the wooden formwork 5 according to the size of the mounting hole 4 and fix it between the two angle aluminums 2, and at the same time open the avoidance hole 6 on the wooden formwork 5 according to the position of the lifting hook 7 of the civil air defense door; finally, take the lifting hook 7 of the civil air defense door, insert its lower part into the avoidance hole 6, and paste and seal the joints between the wooden formwork 5 and the aluminum formwork 1 with tape.

[0016] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
