Abstract

The utility model relates to a connecting piece of a joint part of a steel and concrete combined structure, which is used for connecting a steel beam and the concrete. The connecting piece is a high-strength friction type bolt composed of an upper nut, a lower nut and a stud, wherein the upper nut is arranged at the top part of the stud and the lower nut is arranged at the bottom end of the stud. Compared with the prior art, under the precondition of assuring that the steel and the concrete in the steel and concrete combined structure are effectively connected, the welding working amount of a construction site can be reduced compared with other traditional form connecting pieces, the cost for manufacturing and mounting is reduced, the construction speed of a project is accelerated and the total construction cost of the project is reduced.

Description

The connector of a kind of steel and concrete combined structure joint area
Technical field
The utility model relates to a kind of connector, especially relates to the connector of a kind of steel and concrete combined structure joint area.
Background technology
At present, the girder steel joint area generally has two kinds of form of structure in steel and concrete combined structure, shear connector is not set and on scab on the structure position, welds shear connector at structure position.If shear connector is not set at structure position, can cause this place's steel with concrete combine a little less than, girder steel can bear bigger load, makes that original weak jointing was stressed more unfavorable.If on scab on the joint area, weld shear connector, tend to have influence on the operation of tightening of high-strength bolt, cause the layout quantity of shear connector to be restricted.And under load action, the stressed of shear connector will directly be passed to scab, make that going up scab bears bigger local load, can cause that the part of going up scab starts or levers up.
Because develop a kind of novel steel and concrete combination beam joint connector for guaranteeing that effectively connecting between steel and the concrete has crucial meaning.
The utility model content
The purpose of the utility model is exactly a kind of convenient construction to be provided and to reduce the steel of welding job amount and the connector of concrete combined structure joint area for the defective that overcomes above-mentioned prior art existence.
The purpose of the utility model can realize through following technical scheme:
The connector of a kind of steel and concrete combined structure joint area; Be used to connect girder steel and concrete; It is characterized in that; Described connector is the high-strength friction-type bolt that top nut, lower nut and double-screw bolt constitute, and described top nut is located at the top of double-screw bolt, and described lower nut is located at the bottom of double-screw bolt.
Described double-screw bolt is fixedly connected on through lower nut on the scab of top flange of girder steel.
Described double-screw bolt top is located in the concrete.
Compared with prior art; The utility model is in guaranteeing steel and concrete combined structure under steel and the prerequisite that concrete effectively is connected; Can reduce building site welding job amount with respect to other traditional form connector; Reduce the fabrication and installation cost, accelerate the speed of application of engineering, reduce the total cost of engineering.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the mounting structure sketch map of the utility model.
1 is that girder steel, 11 is top nut for lower nut, 53 for double-screw bolt, 52 for connector, 51 for weldering nail, 5 for top flange scab, 4 for concrete slab, 3 for top flange, 2 among the figure.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
A kind of compound beam bolt connection piece, its mounting structure is as shown in Figure 1, is used to connect girder steel 1 and concrete slab 2; Need on girder steel top flange 11 and top flange scab 3, bore the round screw; Penetrate the double-screw bolt 51 of high-strength bolt afterwards, and tighten the pretightning force of lower nut 52 to high-strength bolt requirement, and be screwed into top nut 53; Last concreting plate 2 forms steel and concrete combination beam.
The structure of the utility model is as shown in Figure 2, the high-strength friction-type bolt that connector 5 constitutes for top nut 53, lower nut 52 and double-screw bolt 51, and top nut 53 is located at the top of double-screw bolt 51, and lower nut 52 is located at the bottom of double-screw bolt 51.Double-screw bolt 51 is fixedly connected on through lower nut 52 on the top flange scab 3 of girder steel 1, and double-screw bolt 51 tops are located in the concrete slab 2.
A kind of compound beam bolt connection piece of the utility model is applied in steel and the concrete combined structure; Can couple together steel work and concrete structure effectively; Its catenation principle is following: through since the effect of lower nut can be effectively with bolt to girder steel; Go in the concrete because top nut is buried, can effectively realize being connected between connector and the concrete, and the screw thread on the double-screw bolt interconnects effect between reinforced company's fitting and the concrete greatly.
Therefore, this connected mode is applied in effective connection that can guarantee in steel and the concrete combined structure between connector and the steel work part, and its welding job amount is little, and is convenient to construction, can accelerate speed of application, practice thrift cost.

Claims (3)

1. the connector of steel and concrete combined structure joint area; Be used to connect girder steel and concrete; It is characterized in that; Described connector is the high-strength friction-type bolt that top nut, lower nut and double-screw bolt constitute, and described top nut is located at the top of double-screw bolt, and described lower nut is located at the bottom of double-screw bolt.
2. the connector of a kind of steel according to claim 1 and concrete combined structure joint area is characterized in that, described double-screw bolt is fixedly connected on through lower nut on the scab of top flange of girder steel.
