Description

A prefabricated building column-slab assembly structure

technical field

The utility model relates to the technical field of building assembly, in particular to an assembled building column-plate assembly structure.

Background technique

Prefabricated buildings refer to the pre-production and processing of various components of the building in the factory to form corresponding modules, and then directly moved to the construction site for assembly and combination. It can maintain better and effectively reduce dust pollution and noise pollution, so it is popularized by many large-scale cities.

Especially in the construction of temporary buildings, such as emergency hospitals, temporary venues, etc., it pays great attention to the construction speed, so the prefabricated construction method is particularly suitable. Adjusting and splicing seriously affects the construction progress, especially the direct splicing of key structures such as column-slab structures, which plays a decisive role in the construction progress. Therefore, a more reasonable design is required to improve the convenience of construction.

Utility model content

The technical problem to be solved by the utility model is to provide a prefabricated building column-slab splicing structure, which has a simple splicing structure and improves the speed of on-site construction.

The utility model specifically includes a floor plate and a column body. The floor plate is a rectangular structure with a certain thickness, and the column body is a square column structure. The floor plate and the column body are generally made of prefabricated concrete. A square sleeve column is fixedly arranged on the upper part, and the square sleeve column is also a square column structure, and there is a fixed cavity which is also a square column inside. The cross-sectional dimensions of the upper end of the cylinder are the same, then the upper end of the cylinder can be inserted and fixed into the fixed cavity from the lower part of the square sleeve column, and the fixed cavity is filled. Inside, the wall thickness of the square set of columns is equivalent to the slab thickness of the floor slab.

A supporting edge beam is fixed between the outer wall of the square set of columns and the lower side of the floor slab. The side view of the supporting edge beam is a right-angled triangle. The supporting edge beam increases the fixing and stable effect of the square set of columns. The lateral force on the square set of columns is transmitted to other parts of the floor, so as to prevent the square set of columns from cracking due to unbalanced force. cast.

The inner width of the lower part of the square sleeve column gradually increases as it goes down, that is, the inner width of the part close to the lower end becomes wider and wider, so that the side view cross-sectional shape of the inner wall of the lower part of the square sleeve column is an arc shape, then the square sleeve column has an arc shape. The inner dimension of the section at the lower part of the column is larger than that of the upper end of the column, which is convenient for the upper end of the column to be inserted into the square sleeve column at the beginning of hoisting. The assembly structure is simple, and there is no cumbersome docking operation. It is suitable for emergency building construction.

Specifically, the number of supporting side beams disposed on the outer wall of each side of the square sleeve column is two.

Further, an inner metal sheet is fixed on the inner wall of the square sleeve column. Since the external friction coefficient of the metal sheet is significantly lower than the friction coefficient of the concrete structure surface, the resistance existing in the insertion process of the column can be reduced, and the When the metal material is squeezed, it will produce a certain deformation, and it can also increase the compactness of the column body inserted into the square sleeve column.

Further, the lower end of the inner metal sheet is bent outward to form an outer fixing edge, and the outer fixing edge is tightly fixed on the outer wall of the lower end of the square sleeve column. It brings upward sliding force, and the lower bending part of the inner metal sheet and the outer fixed edge are equivalent to being stuck at the lower end edge of the square sleeve column, so as to prevent the inner metal sheet from sliding upwards and sideways.

Further, the top side of the cylinder and the outer side of the upper end portion of the cylinder are covered and fixed with a metal surface sheet, which has the same effect as the inner metal sheet, reduces the resistance of splicing and insertion, and improves the compactness.
