Precast spliced concrete slab wall body

Abstract

The invention discloses a precast spliced concrete slab wall body, which comprises an inner wall panel, an outer wall panel and an intermediate concrete layer. The inner wall panel and the outer wall panel are formed by splicing precast concrete slabs, the middle part of the concrete layer is provided with a steel reinforced frame, the steel reinforced frame is arranged along the whole length direction of the wall body and is connected with a bearing component on the wall edge, and horizontal steel wires are arranged at certain intervals along the height direction of the steel reinforced frame; and the inner surfaces of the inner wall panel and the outer wall panel are respectively provided with a prismatic table type bulge, and positioning steel wires parallel to the plate direction penetrate out of the prismatic table, are arranged in a triangular shape and are in clamping connection with the horizontal steel wires in the steel reinforced frame of the wall body. The invention has the advantages of good wall integrity, convenient construction, no need for formwork removal, low average density and good thermal insulation performance. Moreover, for the wall body constructed in the method, the manufacturing cost per unit area can be reduced.

Description

technical field [0001] The invention relates to a wall structure, in particular to a prefabricated spliced ​​concrete slab wall. Background technique [0002] At present, building walls can be roughly divided into three categories according to different structures and construction methods: the method of block and plastering, the method of on-site splicing of prefabricated multi-layer parallel plates and the method of integral pouring. [0003] The main disadvantage of the block plastering method is that the construction process is long, but due to the simple construction and low cost, it is the main wall construction method in current buildings. However, the integrity of the wall formed by the blocks is not good, and it is often difficult to achieve both thermal insulation and waterproofing. [0004] The main disadvantages of prefabricated multi-layer parallel panels are complex structure, poor waterproof performance when applied to external walls, and high cost. [0005] ...

AI Technical Summary

Problems solved by technology

On the one hand, due to the large area of ​​the wall, the cost of the formwork project is considerable

On the other hand, if lightweight concrete is used to reduce the cost of raw materials, the practicability of the wall will be reduced due to material strength issues, such as the mounting capacity and durability are difficult to meet the requirements

Compared with the wall cost of the block method, although the pouring method requires very little man-hours in the final pouring process, the cost of raw materials and form work far exceeds the overall cost of the masonry method, which leads to the cost of the wall project. The pouring method is difficult to popularize
