Detailed Description

The embodiment of the utility model provides a structural steel stiffening pin key type steel plate shear wall which comprises a group of side columns, a group of steel plates and a plurality of high-strength bolts, wherein the two sides of the group of steel plates are symmetrically connected between the group of side columns, mounting holes are formed in the steel plates, the high-strength bolts penetrate through the mounting holes to fix the group of steel plates, concrete is poured into spaces between the group of side columns and the steel plates, a steel reinforcement cage can be arranged for pouring, and semicircular grooves which are arranged inwards are fully formed in the steel plates.

There are various types of connection methods between the side pillar and the steel plate, and as shown in fig. 1(a), in the conventional connection method, the side of the side pillar is directly welded to the side of the steel plate.

As shown in fig. 1(b) in combination with fig. 4, vertical inserted rods are arranged at two ends of the steel plate, arc opening type lantern rings are fixedly arranged on the side edges of the side columns correspondingly, the inserted rods are inserted into the lantern rings, one side of each lantern ring is welded with the side column, and one side of each inserted rod is welded with the steel plate. Therefore, the connection between the side column and the steel plate is formed by the insertion of the insertion rod and the lantern ring.

As shown in fig. 3, examples of the side pillar include a square steel pipe type, an H-shaped steel type, or a channel steel type.

Specifically, the high-strength bolt can adopt a structure that an internal thread sleeve is added with bolts screwed into two ends, and can also adopt a pair of extension rod bolt connection.

The side columns and a group of steel plates can be combined into various forms, the structural arrangement forms of the side columns include a straight shape as shown in figure 1, and the side columns further include an L shape, a T shape, a Z shape or a cross shape and the like, and the side columns are built according to different requirements of application scenes.

The working principle is as follows: this shaped steel pin key formula steel sheet scissors wall of putting more energy into, by the steel sheet that two symmetries were placed, the intussuseption concrete, the high strength bolt of side post and two steel sheets of connection is constituteed, install the fixed field ground with the side post earlier, steel sheet and side post welded connection, two steel sheets pass in order to realize its connection through laying circular mounting hole high strength bolt on its surface, the mounting hole evenly arranges on the steel sheet surface, hug closely the steel sheet of one side with the internal thread sleeve pipe, and twist the high strength bolt of one side wherein, cover another steel sheet, and twist the high strength bolt of opposite side, carry out concrete placement to the space between the steel sheet, treat concrete placement completion and solidify the back, form shaped steel pin key formula steel sheet scissors wall integrated configuration.

This shaped steel pin key formula steel sheet scissors wall integrated configuration that puts more energy into can be applied to among the wall limb structure among the many high-rise structures, possesses apparent advantage: wall limb structure often comprises multiunit shaped steel pin key formula steel sheet scissors wall of putting more energy into, and every group steel pin key formula steel sheet scissors wall of putting more energy into constitutes the parcel concrete by side post and a set of steel sheet and constitutes, through to extension bar bolted connection between the outer interior steel sheet, treat that concrete placement accomplishes and solidify the back, applys the pretightning force to the split bolt, forms the side direction restraint effect to the concrete, and then improves the design strength of concrete. Because the steel plate with the semicircular grooves is arranged, the vertical bearing capacity of the steel plate can be effectively improved. The buckling load under the action of vertical pressure and shearing force is beneficial to improvement, and the stressed and sheared buckling load of the steel plate is higher than that of a flat steel plate with the same size.
