Abstract

The utility model discloses a shear-resistant connector applied in a steel-concrete combination bean structure, which comprises a perforated steel plate and another steel plate welded on the top portion of the perforated steel plate, wherein the perforated steel plate and the other steel plate are combined to form a perforated steel plate connector in T-shaped structure. After utilizing the technical scheme, concrete can flow through holes of the perforated steel plate to form concrete tenons for playing a role of longitudinal shear-resistance, or reinforced bars can be penetrated into the holes on the perforated steel plate to further realize a function of longitudinal shear resistance, because the reinforced bars have fine extensibility, stress property of the connector can be improved better. The other steel plate of the perforated steel plate can greatly increase capacity of resisting vertical separation of the connector, and strengthens combination degree of the steel-concrete combination bean, thereby increasing stress property of the combination bean. The connector can improve and increase properties of the connector in the combination bean at present and can be widely used in fields of building construction, bridge structure and the like.

Description

A kind of shear connector
Technical field
The utility model relates to field of civil engineering, specifically is a kind of shear connector.
Background technology
Steel-concrete composite beam is present widely used horizontal load-bearing combined member, can give full play to the high and good advantage of steel tensile property of concrete crushing strength, compound beam is used widely in the newly-built or strengthening and rebuilding engineering of various form of structure such as bridge construction, building structure, industrial premises and underground structure at present.And steel-concrete composite beam need be combined into whole and cooperative flexural member with girder steel and armored concrete slab by multi-form shearing connecting piece.Wherein shear connector is that girder steel and concrete slab are combined cooperative critical component.Shear connector mainly plays the effect of vertical shearing resistance in compound beam, thereby makes concrete slab and girder steel form the compound section, and is in pressurized and tension state under the moment of flexure effect respectively.
Shear connector is divided into rigid connector and flexible connecting member two big classes according to loading characteristic in the compound beam.The perforate steel plate is a kind of novel rigid connector, the perforate steel plate mainly plays vertical shearing resistance effect in compound beam, but except that vertical shearing resistance, shear connector also needs to resist the vertical separation trend between concrete flange plate and girder steel, and the perforate steel plate exists the vertical relatively poor problem of ability of separating of opposing.
The utility model content
The purpose of this utility model provides a kind of ability of vertical separation and vertically shearing resistance of resisting all than strong and shear connector.
The technical solution adopted in the utility model is: a kind of shear connector, comprise the perforate steel plate, and the top vertical welding of described perforate steel plate is connected to another steel plate, and above-mentioned perforate steel plate is connected with above-mentioned another steel plate and is combined into T type structure.
Hole on the above-mentioned perforate steel plate is a circular hole.
Hole on the above-mentioned perforate steel plate is a polygonal hole.
After adopting such scheme, shearing resistance connection of the present utility model has following beneficial effect:
1, concrete can pass the hole of perforate steel plate, forms the concrete tenon, plays vertical shearing resistance effect;
2, can in the hole on the perforate steel plate, penetrate reinforcing bar, thereby further play vertical shearing resistance effect, and, can better improve the connector stress performance because reinforcing bar has the favorable extensibility energy by reinforcing bar;
3, another steel plate of perforate steel plate welded top can greatly improve the vertical ability of separating of opposing of connector, strengthens the combined level of steel-concrete composite beam, thereby improves the compound beam stress performance;
4, at the negative moment area of continuous composite beam, another steel plate of perforate steel plate welded top can play the tensile reinforcement effect simultaneously, thereby effectively improves the supporting capacity of compound beam at negative moment area;
5, shear connector of the present invention can be made the long connector of length, is used for bridge construction, because supporting capacity height, fatigue behaviour are good, has fine promotional value;
6, shear connector of the present invention can be made the less connector of length, is used for the effect that peg is played in building structure, because convenient welding and quality guarantee easily, so have promotional value.

The specific embodiment
A kind of shear connector of the present utility model, embodiment one comprise the perforate steel plate 1 that offers three circular holes 11 as shown in Figure 1, 2, and the top vertical welding of perforate steel plate 1 is connected to steel plate 2, and perforate steel plate 1 is connected into T type structure with steel plate 2.
A kind of shear connector of the present utility model, embodiment two as shown in Figure 3, the difference of itself and embodiment one only is: only offer a circular hole 11 on the perforate steel plate 1.
A kind of shear connector of the present utility model, embodiment three as shown in Figure 4, the difference of itself and embodiment one only is: three holes that perforate steel plate 1 is offered are polygonal hole 12.
A kind of shear connector of the present utility model, embodiment four as shown in Figure 5, the difference of itself and embodiment three only is: only offer a polygonal hole 12 on the perforate steel plate 1.
During use, the perforate steel plate in the shear connector of the present utility model is vertically welded on the girder steel, penetrates reinforcing bar in the hole that sets in advance or do not penetrate reinforcing bar in the perforate steel plate, the concreting plate then forms steel-concrete composite beam then.When girder steel and concrete slab because stressed, when producing horizontal changing of the relative positions power and vertical changing of the relative positions power, the changing of the relative positions between opposing girder steel and the concrete that plays a role of reinforcing bar in the perforate steel plate or concrete tenon, vertical welding is connected to another steel plate opposing girder steel at perforate steel plate top and the vertical changing of the relative positions between the concrete slab simultaneously.
Above-mentioned embodiment is the utility model part embodiment, is protection domain of the present utility model based on claim and the general embodiment of being made of expanding thereof simultaneously.
