technical field

The invention relates to an assembled concrete beam mold.

Background technique

Prefabricated buildings are buildings assembled on site using prefabricated components. The advantage of this kind of building is that the construction speed is fast, it is less restricted by climatic conditions, it saves labor and can improve the construction quality. In the prefabricated frame structure, load-bearing components such as beams and columns play a key role in the overall stability of the structure. Whether the design of beams and columns is reasonable and whether the construction quality is guaranteed determines the strength and overall stability of the entire prefabricated building frame. sex. Especially in earthquake-prone areas, the production and connection quality of prefabricated frame structure beams and columns have a great impact on the seismic performance of the entire building. The main load-bearing components of the prefabricated frame structure system—beams and columns can be industrialized, and the quality can be effectively guaranteed by factory manufacturing and processing. In recent years, extensive research has been carried out on the form of prefabricated frame structures at home and abroad, and continuous improvements and innovations have been made on the original basis to continuously improve the performance of load-bearing structures and the effectiveness of connections.

At present, ordinary prefabricated concrete buildings are limited to the prefabrication of exterior wall panels, interior wall panels, stairs, floor slabs, balcony panels, air-conditioning panels, etc., while beams, columns and even shear walls still need to be cast-in-place. Construction efficiency increases construction cost. On the other hand, it often affects construction quality. Especially in the later installation of hydropower pipelines, slotting, anchoring and other work are often required, which will destroy the integrity and aesthetics of the beam structure, and slightly inadvertent construction , will cause serious security risks.

Further, the minimum width of the pouring trough is 200mm.

Further, the length of the adjustment hole is 30-100mm.

Compared with the prior art, the present invention has the following beneficial effects:

1. The pouring trough of the present invention can be adjusted in the width direction by adjusting the right side plate, and the positions of the front and rear end plates can be designed according to the requirements in the length direction. When pouring, the thickness of the concrete poured into the pouring trough can be controlled according to the requirements , so as to achieve the purpose of pouring concrete beams of various specifications and sizes, so that it is no longer necessary to make molds according to the size of each beam, meet the needs of various prefabricated construction projects, and effectively reduce the cost of production mold making.

2. In the present invention, round pipes are vertically fixed on the left and right sides and bottom of the pouring trough. After the pouring is completed and the mold is demoulded, round holes will be formed on the two sides and the bottom of the finally formed concrete beam. In the prefabricated building When the main body is finished and decorated, the round hole can be directly used for fixed-point installation of water and electricity pipelines and various decorative parts during the interior decoration of the building, so that there is no need to install steel keels, drill holes, slotted pre-embedded fixings, etc. during the decoration. It also avoids slotting and anchoring on the beams, which will damage the integrity and strength of the beams, and ensures the construction quality of the building.
