Construction method for multi-ribbed composite wall

Abstract

The invention discloses a construction method for a multi-ribbed composite wall, which belongs to the technical field of construction of a building structure. The construction method comprises the following steps of: binding a rib column reinforced bar in a rib column position; constructing building blocks of a first layer of lattices; binding the reinforced bar of a first layer of rib beam; constructing concrete in the positions of the first layer of rib beam and the first layer of rib column according to an on-site constructing method; constructing the building blocks of a second layer of lattices; binding the reinforced bar of a second layer of rib beam; constructing concrete in the positions of the second layer of rib beam and the second layer of rib column according to the on-site constructing method; and circularly constructing till finishing the construction of all the building blocks in the wall and the construction of the rib beam and the rib beam concrete, thereby forming the multi-ribbed composite wall. The multi-ribbed composite wall has the beneficial effects that: the construction of hoisting wall plate is unnecessary; the construction of wholly stirring and pouring concrete is also unnecessary; the degree of dependence on mechanical equipment is reduced; the multi-ribbed composite wall has the advantages of simple operation, high adaptability, capability of saving construction cost of civil engineering, and the like; and the multi-ribbed composite wall is beneficial to the promotion of application and popularization of a multi-ribbed structure system in a low-layer and multilayer resident housing construction.

Description

technical field [0001] The invention belongs to the technical field of building structure construction, and in particular relates to a construction method of a densely ribbed composite wall. Background technique [0002] The densely ribbed composite wall is made of reinforced concrete with small cross-section and reinforcement as the frame, embedded with aerated concrete blocks made of industrial waste such as slag and fly ash as the main raw materials. The densely ribbed composite wall structure system with densely ribbed composite wall as the main force-bearing component has the characteristics of light structure weight, good seismic performance, good energy saving effect, and strong structural adaptability. Currently, about 2.9 million square meters of projects have been built. About 500,000 square meters, mainly used for multi-storey and mid-rise residential buildings. [0003] At present, the densely ribbed composite wall generally adopts prefabricated assembly constru...

AI Technical Summary

Problems solved by technology

However, since the densely ribbed composite wall is composed of filling blocks and sash lattices (rib beams, rib columns) in the form of mutual nesting, there are a series of problems in the traditional "masonry wall-structural column" construction method. In: (1) On the one hand, since the wall is mainly made of lightweight blocks, the cross-section and volume of the grid formed by the rib-beam rib-column are small, and the amount of concrete is small, but the number of beams and columns is large; on the other hand , blocks and concrete rib beams and rib columns need to be crossed for construction. Only one layer of concrete rib beams and rib columns need to be poured each time. The concrete used is very little, which belongs to scattered concrete projects

When using machine mixing or manual mixing of concrete, a certain amount of surplus is required, and the mixed concrete needs to be used in time, otherwise, after the hardening period, the concrete can only be treated as construction waste, and the mixing device needs to be moved according to different construction locations , it needs to be cleaned in time after use, so the construction of rib-beam-rib-column concrete in the wall has certain operational difficulties

(2) In the traditional concrete construction, the workability and fluidity of the concrete have certain requirements, and the form work must be carried out in advance. When the amount of concrete is small, especially for the beam-column cross-section and a large number of dense As far as ribbed composite walls are concerned, formwork cutting, retaining, and formwork removal still need to be done, which greatly restricts the progress and speed of wall construction

[0005] From the above analysis, it can be seen that the prefabricated construction method or the traditional "masonry wall-construction column" construction method to construct low-rise dense rib structures have disadvantages such as high earth construction cost, complicated construction process, and slow construction speed. To a certain extent, it restricts the popularization and application of dense rib structure in the field of low-rise residential buildings
