Abstract
The utility model relates to concrete prefabricated shear wall, and specifically a kind of energy improves the concrete prefabricated body of wall with cast-in-place position bonding strength.Described concrete prefabricated body of wall and cast-in-place position joint face are matsurface, described matsurface are arranged at intervals with shearing resistance groove, and described shearing resistance groove is trapezoidal groove.Compared with prior art, the utility model is combined with matsurface by shearing resistance groove, strengthens the bonding strength of cast-in-place position and precast wall body, improves the globality of structure.
Description
Technical field
The utility model relates to concrete prefabricated shear wall, and specifically a kind of energy improves the concrete prefabricated body of wall with cast-in-place position bonding strength.
Background technology
Along with the development of fabricated construction, the bonding strength at prefabricated units and cast-in-place position requires more and more higher, should ensure the globality of structure, meet requirement of strength again.At present, what the position that precast concrete panel is connected with rear pouring concrete adopted is matsurface or keyway; Owing to making concrete retarder unstable properties under steam-cured state of matsurface, and component striking time is also by the impact of component steam-cured time, so concrete matsurface difficult quality guarantee, be also difficult to meet quality requirement with the linkage interface intensity of rear pouring concrete; Reserved keyway is also utilize closeouts mould going out muscle hole to reserve out, and keyway forms a groove on concrete panel, and when rear pouring concrete is built, in groove, easily remained gas steeps, and linkage interface quality also exists hidden danger of quality.Therefore existing connected mode can not meet the globality requirement of structure.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of shearing resistance groove that adopts to combine with matsurface, can improve the concrete prefabricated body of wall with cast-in-place position bonding strength.
The technical scheme that the utility model solves the employing of described problem is:
Can improve the concrete prefabricated body of wall with cast-in-place position bonding strength, described concrete prefabricated body of wall and cast-in-place position joint face are matsurface, described matsurface are arranged at intervals with shearing resistance groove.
Adopt the utility model of technique scheme, compared with prior art, its beneficial effect is: the bonding strength that can ensure concrete prefabricated body of wall and cast-in-place position, improves the globality of structure.
As preferably, the utility model further technical scheme is:
Described shearing resistance groove is trapezoidal groove.
Accompanying drawing explanation
Fig. 1 be the utility model embodiment precast wall body bottom overlap connecting portion schematic diagram;
Fig. 2 be the utility model embodiment precast wall body between cast-in-place connection diagram;
In figure: 1-matsurface; 2-shearing resistance groove; The cast-in-place position of 3-; The concrete prefabricated body of wall of 4-.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail, and object is only better to understand the utility model content.
See Fig. 1, be provided with bottom concrete prefabricated body of wall 4 and the cast-in-place connected node in cast-in-place position 3, the joint face of this position of joints is matsurface 1, and is arranged at intervals with shearing resistance groove 2, and shearing resistance groove 2 is trapezoidal groove.Combined with matsurface 1 by shearing resistance groove 2, strengthen 3(ater-casting, cast-in-place position) with the bonding strength of concrete prefabricated body of wall 4.
See Fig. 2, the side of the concrete prefabricated body of wall 4 of two panels is all provided with shearing resistance groove 2 and matsurface 1, and cast-in-place position 3 is connected by the concrete prefabricated body of wall 4 of shearing resistance groove 2 and matsurface 1 and two panels, guarantees the globality and the bonding strength that connect back wall.
Above-mentioned shearing resistance groove 2, when concrete prefabricated body of wall 4 is built, carrys out indwelling by placing a shear key at a certain distance at position of joints; Above-mentioned matsurface 1 is after concrete final set, removes mould, washes away form with giant.
