Abstract

The invention relates to a horizontally-sliced composite coupling beam with a cave opening concrete wall body and a construction method thereof, belonging to the field of civil engineering. The horizontally-sliced composite coupling beam is mainly applied to construction projects and comprises an upper-layer sub coupling beam, a horizontal isolating layer and a lower-layer sub coupling beam which constitute the horizontally-sliced composite section mode. The beam widths of both of the upper-layer sub coupling beam and the lower-layer sub coupling beam are the same as the wall body thickness. The upper-layer sub coupling beam and the lower-layer sub coupling beam are provided with longitudinal bars and stirrups and are poured by concrete. The longitudinal bars are anchored in the concrete wall columns at two ends; the horizontal isolating layer is arranged between the upper surface of the lower-layer sub coupling beam and the lower surface of the upper-layer sub coupling beam; the horizontal isolating layer is covered by light low-strength materials, such as aerated concrete, foam concrete or polystyrene boards; and the horizontal isolating layer can be used as a bottom formwork of the upper-layer sub coupling beam during construction. The composite coupling beam is beneficial to achieving the idea of strong shear weak bending of coupling beam design and the idea of strong walls and weak beams of wall body design and improves the seismic behavior of concrete wall bodies. In addition, the composite coupling beam is convenient to construct, economical and reasonable and can be popularized and applied to multi-storey and high-rise concrete structure buildings.

Description

With the compound coupling beam of the horizontal slice of concrete body of wall and job practices thereof
Technical field
The present invention relates to the compound coupling beam of a kind of horizontal slice with the concrete body of wall and job practices thereof, be applied to multilayer structure, belong to the building structure technology field.
Background technology
Concrete wall with the hole is widely used in the multilayer structure structure.The coupling beam of wall body door or window hole top connects the wall limb of both sides.The facilities of coupling beam is very large on the anti-seismic performance impact of body of wall.When span less and cross-section of coupling beam height in hole is larger, little by the lintel beam span-depth radio of conventional method design, easily become strong coupling beam, shear failure easily occurs during earthquake, extremely be unfavorable for antidetonation.For above-mentioned situation, the present invention proposes to replace the little lintel beam of span-depth radio that designs by conventional method with the compound coupling beam of horizontal slice, avoid coupling beam that shear failure occurs when earthquake, replace being subjected to curved surrender and bringing into play the power consumption effect of beam-ends, improve the anti-seismic performance with the concrete body of wall.
Summary of the invention
The object of the present invention is to provide the compound coupling beam of a kind of horizontal slice with the concrete body of wall and job practices thereof.
The present invention adopts following technical scheme:
The compound coupling beam of the horizontal slice with the concrete body of wall that the present invention proposes comprises straton coupling beam, horizontal separation layer and lower straton coupling beam, consists of the compound cross-section form that horizontal slice arranges.The deck-siding of upper straton coupling beam and lower straton coupling beam is all identical with thickness of wall body, is furnished with vertical muscle and stirrup, is formed by concreting, and vertical muscle is anchored in the concrete wall wall limb at two ends; Horizontal separation layer all is paved with by isolated material between the soffit of the upper surface of lower straton coupling beam and upper straton coupling beam.
The isolated material of described horizontal separation layer adopts the lightweight low-intensity material, comprises gas concrete, foam concrete or polyphenyl plate, and its compression strength value should be less than 2MPa.
The compound coupling beam of described horizontal slice can have situation about punching for all kinds of concrete walls such as the concrete shear force wall that the hole is arranged, concrete barrels.
The construction sequence of the compound coupling beam of horizontal slice of concrete wall comprises:
When 1, concrete wall is poured into the position that the compound coupling beam of horizontal slice need to be set, make first lower straton coupling beam, comprising conventional construction steps such as formwork supporting plate, the cage of reinforcement that the vertical muscle of sub-coupling beam and the formation of sub-coupling beam stirrup are set, concretings;
2, all lay horizontal separation layer at the concrete upper surface of lower straton coupling beam.When horizontal insolated layer materials was gas concrete, foam concrete bulk, thickness was taken as about 50mm, and required thickness is even;
3, take horizontal separation layer as soffit formwork, carrying out the construction of upper straton coupling beam makes, comprising conventional construction steps such as formwork supporting plate, the cage of reinforcement that the vertical muscle of sub-coupling beam and the formation of sub-coupling beam stirrup are set, concretings, after finishing, construction namely forms the compound coupling beam of horizontal slice.
Adopt the compound coupling beam of above-mentioned horizontal slice, will by the little lintel beam of span-depth radio of conventional method design, replace its function by upper straton coupling beam and lower straton coupling beam.Horizontal separation layer doubles as the soffit formwork of straton coupling beam in when construction, constructs and need not take out after complete.When meeting with severe earthquake action, the body of wall coupling beam deforms, since horizontal insolated layer materials intensity be significantly less than walls concrete intensity (the former generally only for the latter 1/20), very fast crushed, the straton coupling beam can be as the larger coupling beam difference stress deformation of span-depth radio about making, be conducive to realize the strong shear capacity and weak bending capacity of Design of Connecting Beam and the weak beam theory of strong wall of body of wall design, improve anti-seismic performance.
The beneficial effect that the compound coupling beam of the horizontal slice of concrete wall can obtain mainly contains: solved with the problem of concrete body of wall when coupling beam span-depth radio hour poor seismic behavior; The soffit formwork of upper straton coupling beam can satisfy rigidity requirement when horizontal separation layer doubled as construction, and need not to remove constructability; Economical rationality.
Because above-mentioned advantage, the present invention has preferably popularizing application prospect for the band concrete body of wall that is widely used in the multilayer structure structure.
