The utility model discloses a kind of combination opposite-pulling screw rods, including pre embedded bolt (1) and fastening screw (2), fastening screw (2) one end is welded with attaching nut (3), and fastening screw (2) is equipped with buckle (4), is equipped with fastening nut (5) on the outside of buckle (4).The utility model simple structure, it is convenient for disassembly and assembly, operability is good, security performance is high.The very good solution a large amount of Screw arbor with nut at both-ends of outer wall of basement cut off rear unavailable problem, while also solving the quick-fried modulus problem in shear wall root.
Description
Technical field
The utility model relates to a kind of combination opposite-pulling screw rods, belong to hydraulic and hydroelectric engineering metal structure technical field.
Background technique
In the prior art, after the completion of the construction of outer wall of basement Screw arbor with nut at both-ends, a part is embedded in shear wall, and another part is only
It can be as waste disposal；Causing the waste of material event prior art, there is also deficiencies, need to be further improved.
Utility model content
The purpose of this utility model is to provide a kind of combination opposite-pulling screw rods.To improve the utilization rate of material.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of combination opposite-pulling screw rod, including pre embedded bolt and fastening screw, fastening screw one end are welded with attaching nut,
Fastening screw is equipped with buckle, and buckle outside is equipped with fastening nut.
In aforementioned combinatorial formula Screw arbor with nut at both-ends, the attaching nut and fastening screw are thickening nut.
In aforementioned combinatorial formula Screw arbor with nut at both-ends, the plane of the attaching nut side and the side of pre embedded bolt one end are through triangle
Weldering connection.
By adopting the above-described technical solution, the utility model is compared with prior art, the utility model simple structure is torn open
Dress is convenient, operability is good, security performance is high.Very good solution outer wall of basement a large amount of Screw arbor with nut at both-ends cannot utilize after cutting off
The problem of, while also solving the quick-fried modulus problem in shear wall root.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
The label in accompanying drawing is: 1- pre embedded bolt, 2- fastening screw, 3- attaching nut, 4- buckle, 5- fastening nut, 6-
Weld seam.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
A kind of combination opposite-pulling screw rod, as shown in Figure 1.Including pre embedded bolt 1 and fastening screw 2, the weldering of 2 one end of fastening screw
It is connected to attaching nut 3, fastening screw 2 is equipped with buckle 4, and 4 outside of buckle is equipped with fastening nut 5.Attaching nut 3 and fastening screw
2 be thickening nut.The plane of 3 side of attaching nut is connect with three fillet welding of side of 1 one end of pre embedded bolt.
Embodiment
The combination opposite-pulling screw rod of this example is as shown in Figure 1, include the screw rod of two M14, one is used as pre embedded bolt 1, separately
One is used as fastening screw 2；Pre embedded bolt 1 be embedded in shear wall when concrete of basement pours, pre embedded bolt 1 one
Expose shear wall to connect with fastening screw 2 in end；The side of 2 one end of fastening screw is welded with attaching nut 3, and when welding connects
The outer circle that one of plane of 3 six side of nut is tightly attached to fastening screw 2 is welded by way of three fillet welding with fastening screw 2,
Weld seam 6 is fully welded connection in 3 two sides of attaching nut；Then 4 are buckled on 2 sets of fastening screw, buckle 4 is fastened by fastening nut 5.
The length of pre embedded bolt 1 and fastening screw 2 is determine according to actual needs.
