Description

Technical Field

[0001] The present application relates to the technical field of energy dissipation and vibration reduction, and in particular to an embedded component for installing a buckling restraint support. Background Art

[0002] Buckling restrained braces can not only overcome the defects of common braces in that their tensile and compressive bearing capacities are significantly different, but also have the energy dissipation capacity of metal dampers. They are the perfect combination of support components and energy dissipation dampers.

[0003] When buckling restrained braces are used in concrete structures, the node plate embedded parts need to be reserved during the main structure construction phase and then cast in concrete.

[0004] However, the embedded parts in the related art generally adopt the form of bolts and steel bars bound by stirrups, such as a flexure restrained support node plate embedded part disclosed in CN215330525U, which includes an upper flange plate and a lower flange plate, a plurality of strip webs are arranged between the lower flange plate and the upper flange plate, and the gap between the two adjacent webs is a strip opening for passing stirrups; a plurality of first bolts are arranged on both sides of each strip web; second bolts for binding stirrups are arranged on the lower end surface of the upper flange plate, and the second bolts are arranged in two rows, and the two rows of second bolts are respectively arranged on both sides of the strip web, and the two rows of second bolts are relatively arranged on both sides of the strip web, the second bolts are perpendicular to the first bolts, and the first bolts are used to support the steel bars; the strip webs and the upper flange plate and the lower flange plate form an H-shaped structure.

[0005] The fastening method of the above device is: the steel bar is laid on the first bolt, the stirrups fix the steel bar, the stirrups pass through the strip openings to fix the steel bars on both sides of the strip web, and the second bolt is used to support the force of the binding wire.

[0006] However, when using stirrups for fixing, the stirrups need to be passed through the strip openings to tie the steel bars on both sides of the strip web, which is cumbersome and inconvenient, and can easily cause position deviation, making the installation operation of the embedded parts of the buckling restraint support more complicated. Utility Model Content

[0007] In order to improve the convenience of installing the embedded part of the buckling restrained brace, an embedded part for installing the buckling restrained brace is provided.

[0008] The present application provides an embedded part for installing a buckling restraint support, which adopts the following technical solution: an embedded part for installing a buckling restraint support, comprising a plurality of webs, one end of the web being fixedly connected to a lower flange plate, the other ends of the plurality of webs being fixedly connected to the same upper flange plate, a first bolt for binding stirrups being arranged on the lower end surface of the upper flange plate, the first bolt being arranged in two rows, the two rows of the first bolts being relatively arranged on both sides of the web, a support plate being fixed to the web, the end surface of the support plate being perpendicular to the end surface of the web, the support plates being arranged in two rows, the two rows of the support plates being relatively arranged on both sides of the web.

[0009] By adopting the above technical solution, when in use, first determine the position of the embedded part, then insert the embedded part into the predetermined position, make the support plate abut against the steel mesh, so that the entire embedded part is erected by the steel mesh, and then simply fix the entire embedded part preliminarily through stirrups, and then directly weld the abutting surface of the steel mesh and the support plate, and after welding is completed, concrete can be poured.

[0010] Therefore, there is no need to open multiple bolts on the web and perform relatively strong and complicated stirrup tying in sequence. It only needs to be simply fixed and then welded. It has the characteristics of simple operation, time-saving and labor-saving and a strong structure.

[0011] Optionally, second bolts are provided on both sides of the web, and second bolts at the same height on both sides of the same web are arranged opposite to each other, and the second bolts on adjacent webs are arranged on the same horizontal line, and the second bolts and the first bolts are opened perpendicular to each other.

[0012] By adopting the above technical solution, after the embedded part is inserted into the predetermined position, the support plate, the second bolt and the steel mesh can be abutted, so that the entire embedded part is erected by the steel mesh, and then the second bolt and the steel mesh can be simply fixed by stirrups, thereby preliminarily limiting the position of the embedded part, thereby reducing the possibility of misalignment of the embedded part when welding the abutting surface of the steel mesh and the support plate.

[0013] Optionally, a groove is formed on the support plate, and the groove is arranged in a direction parallel to the axis of the first bolt.

[0014] By adopting the above technical solution, the contact area between the abutting surface of the steel mesh and the support plate can be increased through the grooves, thereby improving the stability of the connection between the support plate and the steel mesh.

[0015] Optionally, a reinforcement strip is installed on the support plate.

[0016] By adopting the above technical solution, the support plate can be reinforced by the reinforcement strips to improve the bending resistance of the support plate.

[0017] Optionally, an arc-shaped groove is formed on the reinforcement strip, and the arc-shaped groove is arranged in a direction parallel to the axis of the first bolt.

[0018] By adopting the above technical solution, the stability between the steel mesh and the support plate can be improved by welding the steel mesh or steel bars to the arc grooves provided on the reinforcement strips.

[0019] Optionally, the reinforcement strip is placed on the support plate, and a locking component is provided on the reinforcement strip for fixing the reinforcement strip on the support plate.

[0020] By adopting the above technical solution, the reinforcement strips can be disassembled through the locking assembly, thereby facilitating the installation of embedded parts and adjusting the number of reinforcement strips according to actual working conditions.

[0021] Optionally, a plurality of threaded holes are formed on the support plate, and the locking assembly includes a countersunk bolt, the countersunk bolt is threadedly connected to the reinforcement strip, and the rod of the countersunk bolt is threadedly connected in the threaded hole.

[0022] By adopting the above technical solution, the position of the reinforcement strip can be adjusted by threading the countersunk bolts into different threaded holes, thereby facilitating the adjustment of the position of the reinforcement strip according to the position of the steel mesh.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. There is no need to open multiple studs on the web and perform relatively firm and complicated stirrup tying in sequence. It only needs to be simply fixed and then welded. It has the characteristics of simple operation, time-saving, labor-saving and firm structure.

[0025] 2. The steel mesh or steel bars can be welded to the arc grooves on the reinforcement strips to improve the stability between the steel mesh and the support plate;
