Description

Vertical slot type angle steel connecting device of precast shear wall
Technical Field
The utility model relates to a vertical slot type angle steel connecting device of precast shear wall belongs to building prefabricated component and connects technical field.
Background
Currently, the most common vertical connection modes of precast concrete shear walls are three types, namely steel bar sleeve grouting connection, steel bar grout anchor connection and post-cast strip connection. In the construction site, the grouting material needs to be injected into the steel bar sleeve grouting connection and the steel bar grout anchor connection, and the grouting compactness of the sleeve cannot be guaranteed because the sleeve is totally enclosed. And the post-cast strip connection mode can cause a large amount of wet operation on the site.
In addition, a plurality of section steel connecting methods are developed by a small number of construction units and scientific research institutions to replace steel bars for connection, and the method mainly comprises the step of connecting the embedded steel plates or the section steel of the upper and lower wall plates by bolts or welding seams. The main characteristics of the profile steel connection are that the installation process is rapid and efficient, and the installation quality is easy to detect. However, in some section steel connections, in order to ensure the shear resistance of the connection node, a method of wrapping steel plates on the upper portion and the lower portion of the wall body is adopted, section steel materials are excessively used, the manufacturing cost is high, and a large number of bolt joints and welding seams exist, so that the applicability is reduced. The connection of the existing section steel is simpler, the I-shaped steel or the angle steel is arranged at the upper end and the lower end of the wall, the economical problem is solved, the requirement on the installation precision is higher, the situation that the installation is difficult or even impossible can occur, and the manufacturing and transportation difficulty of the prefabricated part can be increased due to the outward protrusion of the I-shaped steel and the angle steel. In addition, in order to improve the shear strength of connection, vertical steel bars of the upper prefabricated wall and the lower prefabricated wall are lapped, and a post-cast strip is arranged, so that on-site wet operation can be generated when the post-cast strip is poured, and construction is inconvenient.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a simple to operate, labour saving and time saving, improve efficiency of construction's vertical slot type angle steel connecting device of prefabricated shear force wall to overcome not enough among the prior art.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a vertical slot type angle steel connecting device of precast shear wall, including two or two above precast concrete shear walls, it has the recess to reserve respectively in the lower extreme both sides of precast concrete shear wall and upper end one side, pre-buried fixed angle steel in every recess, pre-buried fixed steel sheet has been pre-buried at the opposite side of precast concrete shear wall upper end, there is the overlap joint angle steel through bolt fixedly connected with between the fixed angle steel of adjacent precast concrete shear wall, the welding has the overlap joint steel sheet between the fixed angle steel and the fixed steel sheet of adjacent precast concrete shear wall.
Further, the back of fixed angle steel and fixed steel sheet all welds has the anchor.
Furthermore, corresponding bolt holes are formed in the fixed angle steel and the lap joint angle steel, and bolts penetrate into the bolt holes.
Since the technical scheme is used, the utility model discloses an advantage has below: the utility model discloses pre-buried fixed angle steel and the fixed steel sheet of having respectively at the upper and lower both ends of precast concrete shear force wall, through bolt fixedly connected with overlap angle steel between the fixed angle steel of adjacent precast concrete shear force wall, the welding has the overlap steel sheet between the fixed angle steel of adjacent precast concrete shear force wall and fixed steel sheet, thereby realize the high-speed joint between the precast concrete shear force wall through bolted connection and welded mode, the installation rate and the installation convenience of precast concrete shear force wall have not only been improved, but also the tolerance of installation has been improved. Meanwhile, the pre-embedded fixed angle steels are all arranged in the grooves in the precast concrete shear wall, and only the parts for connection are exposed at the groove openings, so that the manufacturing difficulty of the precast concrete shear wall is reduced, and convenience is provided for component transportation.
