Description

Technical Field

[0001] The utility model relates to the technical field of construction devices, in particular to a pipe fixed formwork assembly for the construction of through-hole beams. Background Technique

[0002] During the construction process, it is often necessary to perforate the beam body to ensure that pipelines and lines can pass through the beam body. Since the building beam body needs to play a load-bearing role, the beam body is usually made of solid reinforced concrete. After the beam body is poured, it is difficult and costly to open holes through drilling equipment. Therefore, pre-burying fixed pipes in the formwork during the pouring of the beam body to be perforated can achieve the effect of directly pouring out a beam body with through holes. In the existing formwork assembly, when installing the fixed casing, to prevent concrete from flowing into the fixed casing due to vibration, a welded fixed structure is mostly used, that is, the two ends of the fixed casing are directly welded to the formwork assembly to seal the connection between the fixed casing and the formwork assembly. However, after the beam body is poured, the formwork assembly needs to be separated from the fixed casing by cutting, which also consumes a lot of manpower and causes great damage to the formwork assembly. Content of the Utility Model

[0003] In view of this, in order to reduce the construction difficulty of the perforated beam body and reduce the damage to the formwork assembly, the utility model provides a pipe fixed formwork assembly for the construction of through-hole beams, which includes a formwork group, a fixed casing and a fixed rod;

[0007] An elastic member is arranged inside the fixed casing, sealing sheets are arranged at both ends of the fixed casing, the elastic member is located between the two sealing sheets, and both ends of the elastic member respectively press the two sealing sheets against the side formwork, so as to seal the two open ends of the fixed casing.

[0008] Further, the formwork group further includes a connecting bottom plate, and the connecting bottom plate connects the bottoms of the two side formworks.

[0009] Further, the two side formworks are arranged in parallel, and the fixed rod is perpendicular to the two side formworks.

[0021] To make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0022] Please refer to Figure 1 and Figure 2 , a pipe fixed formwork assembly for through-hole beam construction, including a formwork group, a fixed sleeve 3 and a fixed rod 4.

[0023] The formwork group includes two side formworks 1 and a connecting bottom plate 11. The two side formworks 1 are arranged in parallel with a certain distance therebetween (this distance is the thickness of the beam body to be constructed). The connecting bottom plate 11 connects the bottoms of the two side formworks. The side formwork 1 is connected to other parts of the construction formwork. In this embodiment, the formwork group is made of aluminum plate structure.

[0024] The fixed sleeve 3 is a cylindrical sleeve body. The fixed sleeve 3 is located between the two connecting bottom plates 11. Both ends of the fixed sleeve 3 are open, and both ends of the fixed sleeve abut against the inner walls of the two side formworks 1. The fixed rod 4 is perpendicular to the two side formworks.

[0025] The fixed rod 4 is located inside the fixed sleeve 3, and the fixed sleeve 3 and the fixed rod 4 are coaxially arranged. Mounting holes that are aligned with each other are provided on the two side formworks 1. Both ends of the fixed rod 4 respectively pass through the two mounting holes, and fasteners are respectively provided at both ends of the fixed rod 4. The fasteners fixedly connect the fixed rod and the side formwork 1.

[0026] An elastic member is provided inside the fixed sleeve 3. Plugging pieces are provided at both ends of the fixed sleeve 3. The two plugging pieces 8, and the elastic member is located between the two plugging pieces 8. The two ends of the elastic member respectively press the two plugging pieces 8 against the side formwork 1, so that the two plugging pieces 8 block the openings at both ends of the fixed sleeve 3. After the formwork assembly is installed, concrete can be poured between the two side formworks 1 to solidify into the beam body 2. Then, the fixing rod 4, the fasteners and the formwork group are removed, and the elastic member and the plugging pieces 8 inside the fixed sleeve 3 are taken out. The fixed sleeve 3 and the beam body 2 solidify into a whole, so as to obtain the beam body 2 with through holes. In the above process, the fixed sleeve 3 is fixed by the fixing rod 4 and the fasteners, so that only hole opening treatment is required on the side formwork of the formwork group, avoiding large-area damage to the side formwork, and the formwork group can be reused repeatedly. At the same time, the plugging pieces in the fixed sleeve of the formwork assembly are pressed by the elastic member to seal the connection between the fixed sleeve 3 and the side formwork 1, which can prevent concrete from flowing into the fixed sleeve 3 due to the vibration effect, thereby improving the construction quality of the through holes on the beam body 2.

[0027] Preferably, connection threads are provided at both ends of the fixing rod. The two ends of the fixing rod 4 respectively pass through the two mounting holes. The fasteners are two fastening nuts 5. The two fastening nuts 5 are threadedly connected to the two ends of the fixing rod 4. The two fastening nuts 5 press the outer surfaces of the two side formworks 1. Fixing gaskets 6 are also sleeved on the two ends of the fixing rod 4. The fixing gaskets 6 are located between the fastening nuts 5 and the side formwork 1. The fastening nuts 5 press the side formwork 1 through the fixing gaskets 6. Friction layers 61 are provided on the surfaces of the two fixing gaskets 6. The friction layers 61 are located between the fixing gaskets 6 and the side formwork 1. The friction layers 61 are made of materials that can increase the friction coefficient (the friction layer can be made of rubber material, carbon fiber material, etc.). The fastening nuts 5 enable the fixing rod 4 to be conveniently installed and removed, which can reduce the construction difficulty of the perforated beam body and improve the construction efficiency. The fixing gaskets 6 and the friction layers 61 keep the fixing rod 4 fixed through the pressing force of the fastening nuts 5, avoid the deviation of the fixed sleeve 4 during the vibration of the concrete slurry, and prevent the concrete slurry from overflowing from the mounting holes.

[0028] Preferably, the elastic member is a helical spring 7. The helical spring 7 is sleeved on the fixing rod 4. The two plugging pieces 8 are both rubber round pieces. Limiting rings 81 are provided on the two plugging pieces 8. The two ends of the helical spring 7 are respectively limited within the limiting rings 81 of the two plugging pieces 8. The plugging pieces 8 are set as rubber round pieces, which can make them elastic and facilitate the subsequent removal of the plugging pieces 8 from the fixed sleeve 3 for reuse. The limiting rings 81 are used to limit the helical spring 7.
