Abstract
The utility model discloses a pressure-relieve back bolt, which is composed of a screw rod, a pressure-relieve ring, an extruded element and a screw nut, wherein the pressure-relieve ring is an elastic steel ring. The utility model has the advantages of high structural safety, fixed anchorage and easy recycling.
Description
Technical field
The utility model belongs to the technical field of building anchor bolt, relates to a kind of decompression type back of the body bolt.
Background technology
At present, the building curtain wall is installed and is cut end formula after the back of the body bolt that is adopted is, its structure is made up of screw rod 10, supercharging ring 20, extrusion 30 and nut 40 as shown in Figure 1, and supercharging ring 20 is special-shaped elastic component.It is used for curtain wall when installing as shown in Figure 2, in the perforate of the back side of curtain wall 50, this hole has 502 two sections of straight hole 501 and trapezoidal holes, supercharging ring 20 and extrusion 30 are enclosed within on the screw rod 10, expanding end with screw rod 10 inserts in the hole of curtain wall 50 again, screw by the threaded engagement of nut 40 with screw rod 10, promoting extrusion 30 and supercharging ring 20 moves in the hole of curtain wall 50, extrusion 30 extruding supercharging rings 20 expand in trapezoidal hole 502 along the expanding end of screw rod 10, make to form closely between the hole of screw rod 10 and curtain wall 50 and contact and firmly fix together, and the fixed end of screw rod 10 is passed the through hole of body of wall suspension member 60, be fastened on the suspension member 60 by the fixed end of another nut 40, thereby curtain wall 50 is installed in surface of wall screw rod 10.
Anatomize said structure, be not difficult to find: supercharging ring 20 is that line contacts with curtain wall 50 ways of contact, calculates according to projection, and contact area is equivalent to carry on the back 1/2 of bolt screw rod 10 sectional areas.When back of the body bolt is subjected to load action, supercharging ring 20 will be the multiple of back of the body bolt screw rod 10 tensile strength with curtain wall 50 footprint pressures.Example: during back of the body bolt tension, during screw rod 10 tensile strength 400Mpa, supercharging ring 20 has reached 800Mpa with the footprint pressure of curtain wall 50, and if select for use stone material to do curtain wall 50, the maximum compressive strength of stone curtain wall 50 but has only 200Mpa, poor stability; And the base angle of curtain wall 50 trapezoidal holes 502 is less than 90 degree, and stress is concentrated, and fatigue cracks easily, causes anchoring to be lost efficacy; Moreover, the complex structure in hole on the curtain wall 50, the boring requirement height, bore error easily takes place in construction, causes phenomenon at the bottom of the sham cut, further causes anchoring to be lost efficacy; In addition, back of the body bolt promptly can't take out once installing, and discarded back of the body bolt can't reclaim, and is unfavorable for environmental protection.
In view of this, the inventor has developed a kind of decompression type back of the body bolt, and to address the above problem, this case is arisen spontaneously.
The utility model content
The purpose of this utility model be to provide a kind of safe, anchoring firmly, reclaim and be easy to decompression type back of the body bolt.
In order to reach above-mentioned purpose, solution of the present utility model is:
Decompression type back of the body bolt is made up of screw rod, pressure-reducing ring, extrusion and nut, and pressure-reducing ring is a flexible steel ring.
The above-mentioned flexible steel ring outside is cylindric, and the inboard is the face of cylinder and taper seat intersects, and has groove on the sidewall.
Set up a pad between above-mentioned nut and the extrusion.
After adopting said structure, the utility model is because replace special-shaped elastic component with flexible steel ring, so, when being used for curtain wall and installing, only need open straight hole at the back side of curtain wall and get final product, mounting means is identical with located by prior art.Because the pressure transmission of pressure-reducing ring and curtain wall is undertaken by contact area, therefore, contact area can be designed to carry on the back more than 10 times of bolt screw rod sectional area, for example: when the tensile strength of back of the body bolt screw rod reaches 400Mpa, pressure values between pressure-reducing ring and the curtain wall has only 400/10=40Mpa, and curtain wall is installed safety; And curtain wall is opened straight hole, and the base angle is 90 degree, and boring is easy, and unstressed localization effects is avoided crackle, and anchoring is firm; Moreover straight hole cooperates with flexible steel ring, is convenient to discarded back and takes out, reclaims, and helps environmental protection.

Specific embodiment
Seeing also shown in Figure 3ly, is that the utility model has disclosed decompression type back of the body bolt, is made up of screw rod 1, pressure-reducing ring 2, extrusion 3 and nut 4, pressure-reducing ring 2 is a flexible steel ring, the flexible steel ring outside is cylindric, and the inboard is the face of cylinder and taper seat intersects, and has groove 21 on the sidewall.In order to make nut 4 fixations, also set up a pad 7 between nut 4 and the extrusion 3.
When the utility model is used for the curtain wall installation, as shown in Figure 4, only need opens straight hole 51 at the back side of curtain wall 5 and get final product.Pressure-reducing ring 2 and extrusion 3 are enclosed within on the screw rod 1, expanding end with screw rod 1 inserts in the straight hole 51 of curtain wall 5 again, screw by the threaded engagement of nut 4 with screw rod 1, promoting extrusion 3 and pressure-reducing ring 2 moves in the straight hole 51 of curtain wall 5, extrusion 3 extruding pressure-reducing rings 2 expand in straight hole 51, make to form between the straight hole 51 of screw rod 1 and curtain wall 5 and closely contact and fix, and the fixed end of screw rod 1 is passed the through hole of body of wall suspension member 6, be fastened on the suspension member 6 by the fixed end of another nut 4, thereby curtain wall 5 is installed in surface of wall screw rod 1.
When the utility model is used for the curtain wall installation, also can be as shown in Figure 5, the screw rod 1 that will be with pressure-reducing ring 2 and extrusion 3 earlier inserts in the straight hole 51 of curtain wall 5, by nut 4 extrusion 3 and pressure-reducing ring 2 are pushed in the straight hole 51 of curtain wall 5, pressure-reducing ring 2 is expanded in straight hole 51, make the expanding end of screw rod 1 be fixed in the straight hole 51 of curtain wall 5, take off nut 4 again, the fixed end of screw rod 1 is passed the through hole of body of wall suspension member 6, be fastened on the suspension member 6 with the fixed end of previous nut 4, thereby curtain wall 5 is installed in surface of wall screw rod 1.This embodiment and difference shown in Figure 4 are: only with a nut 4, its effect is equal to.
