Abstract
Tensile bolt nut subassembly relates to building toughened structure technical field, especially belongs to a cooperation fastener for building. The anti-stretching bolt comprises a bolt, a fastening nut and a tensile nut, wherein the bolt comprises a screw head and a stud, the stud is a step cylinder, threads are arranged on two layers of step cylinders and are respectively matched with the fastening nut and the tensile nut, and the tensile nut is connected with a plurality of tensile rods. The tensile rods are fixed after concrete is poured, so that the tensile performance of the whole structure is improved, and the risk of loosening and even pulling off is reduced.
Description
Technical Field
The utility model relates to a building tempering technical field especially belongs to a cooperation fastener for building.
Background
Compared with the traditional concrete building, the steel plate or the section steel replaces reinforced concrete, so that the steel structure building has higher strength and better shock resistance. And because the components can be manufactured in factories and installed on site, the construction period is greatly reduced. Because the steel can be repeatedly used, the construction waste can be greatly reduced, and the steel is more environment-friendly, so the steel is widely adopted by all countries in the world and is applied to industrial buildings and civil buildings. The steel structure construction uses modes such as welding, riveting, bolt and the like for connection. The bolt connection structure is simple, the type is various, firm and reliable, the assembly and disassembly are convenient, and the cost is low. But under alternating loads, the risk of loosening and even pull-off is likely to occur.
Disclosure of Invention
An object of the utility model is to provide a bolt and nut subassembly that cooperation is fixed for building reaches and prevents under the alternating load, takes place not hard up purpose.
The utility model provides a tensile bolt nut subassembly, a serial communication port, including bolt (1), fastening nut (2), tensile nut (3), the bolt include spiral shell head, double-screw bolt, the double-screw bolt is the step cylinder, all is equipped with the screw thread on the two-layer step cylinder, respectively with fastening nut and tensile nut cooperation, tensile nut on link many anti-stretching rods (4).
Furthermore, threaded holes are uniformly formed in the side face of the tensile nut, and one end of the tensile rod is correspondingly provided with threads which are matched and fixedly connected with the threaded holes.
Furthermore, two threaded holes are symmetrically formed in the tensile nut, and the two tensile rods are connected with the tensile nut in a matched mode.
The utility model provides a tensile bolt nut subassembly connects many stretch-proofing poles on the tensile nut, and stretch-proofing pole is fixed after the pouring concrete, has increased the tensile property of overall structure, reduces to take place not hard up risk of drawing off even.
Drawings
The accompanying drawings partially disclose embodiments of the present invention, in which,
figure 1 is a schematic structural diagram of the present invention,
FIG. 2 is a schematic structural view of the tensile nut and the tensile bar of the present invention,
fig. 3 is a schematic view of an application state of the present invention.
Detailed Description
As shown in fig. 1-2, the utility model provides a tensile bolt and nut assembly, which comprises a bolt 1, wherein the stud is a step cylinder, one end of the stud connected with the head of the bolt is a thick stud, a fastening nut 2 is matched with the thick stud, the other end of the stud is a thin stud, and a tensile nut 3 is matched with the thick stud; the tensile nut is connected with a plurality of tensile rods 4.
The utility model is characterized in that, the symmetry sets up two screw holes on the tensile nut, and the tip correspondence of two anti-stretching rods sets up the screw thread, screw thread and screw hole cooperation fixed connection, and two anti-stretching rods are a style of calligraphy and arrange.
In the present embodiment, the application environment is the connection between the load beam 5 and the shear wall connection beam 6. The bolt passes through the through holes preset on the shear wall tie-beam and the spandrel girder in proper order, and the fastening nut is matched with the through holes to fix the shear wall tie-beam and the spandrel girder, and at this moment, the tail end of the bolt is in the spandrel girder, and the tensile nut is fastened to the tail end of the bolt, and the tensile rod is connected to the tensile nut, and concrete 7 is poured in the spandrel girder, and the tensile rod is fixed by the concrete.
Claims (3)
1. The tensile bolt and nut assembly is characterized by comprising a bolt (1), a fastening nut (2) and a tensile nut (3), wherein the bolt comprises a screw head and a stud, the stud is a stepped cylinder, threads are arranged on the two layers of stepped cylinders and are respectively matched with the fastening nut and the tensile nut, and the tensile nut is connected with a plurality of tensile rods (4).
2. The tension bolt nut assembly as claimed in claim 1, further characterized in that the tension nut is provided with a plurality of threaded holes uniformly formed in the side surface thereof, and one end of the tension bar is correspondingly provided with a plurality of threads to be fixedly connected with the threaded holes in a matching manner.
