Abstract

A steel plate concrete shear wall connecting beam bestrewed with toggle pins belongs to the field of construction works and is composed of a connecting beam longitudinal bar 4, a connecting beam stirrup 5, connecting beam concrete 6, a steel plate 10 and toggle pins 9. The steel plate concrete shear wall connecting beam bestrewed with toggle pins is characterized by being a building or a structure constructed with the steel plate concrete shear wall connecting beam bestrewed with toggle pins internally arranged and concrete shear wall nodal points serving as nodal points. The steel plate concrete shear wall connecting beam bestrewed with toggle pins utilizes high shear strength and good plasticity of the steel plate to resist external force together with reinforced concrete, not only improves bearing capacity but also avoids brittle shear failure of the connecting beam, and enhances ductility and energy consumption capacity of the connecting beam under the action of an earthquake. The steel plate concrete shear wall connecting beam bestrewed with toggle pins is suitable for being used in high-rise and mega-high-rise buildings, and can be used respectively as the concrete connecting beam of a large cross section or a small cross section.

Description

The steel plate concrete shear wall that is abound with peg connects beam

Technical field

The utility model relates to a kind of building unit, particularly relates to a kind of steel plate concrete shear wall that is abound with peg and connects beam.

Background technology

Shear wall is a main lateral resistant member high-rise and super highrise building, is made up of wall horizontal bar 1, the vertical muscle 2 of wall, the concrete 3 of building; Lian Liang is made up of the vertical muscle 4 of beam, beam stirrup 5, the concrete 6 of building, and sees Fig. 1～Fig. 3 for details.Lian Liang is the connection power transmission hinge between the shear wall, and the key position that is structure also is a weak part, because it is generally less to connect the girder span height ratio; So it is relatively poor that ordinary reinforced concrete connects the ductility of beam, this anti-seismic performance for building structure is unfavorable, in recent years; Because steel and concrete composite coupling beams have the two-fold advantage of steel work and concrete structure concurrently; Bearing capacity is high, and anti-seismic performance is good, more and more is widely used among high-rise and the super highrise building.

In " reinforced concrete composite structure tecnical regulations " (JGJ 138-2001) of China, " steel reinforced concrete structure tecnical regulations " (YB 9082-2006); The concrete regulation that does not also connect beam about steel and combined concrete shear wall; In engineering, using at present maximum is that the i shaped steel concrete connects beam; It is a kind of the company at ordinary reinforced concrete to have inserted the compound beam that i shaped steel forms in the beam; I shaped steel is made up of the peg 9 of the edge of a wing 7, web 8 and welding above that, sees Fig. 4～Fig. 6.

Steel reinforced concrete connects beam, because supporting capacity and ductility that the adding of shaped steel has improved; And shaped steel has solved the problem of the stable and fire resistance difference of steel because of the concrete parcel in outside.In the engineering design of present stage; When common even load bearing beam power or ductility deficiency, adopt the i shaped steel concrete to connect the beam form usually, but the edge of a wing of i shaped steel makes troubles can for again the layout of the longitudinal stress muscle of shear wall edge constraint member; Cause constructional difficulties, see Fig. 5, Fig. 6.

Summary of the invention

The purpose of the utility model is to provide a kind of steel plate concrete shear wall that is abound with peg to connect beam, and the steel plate of employing belongs to plane institution movement, remove from the steel plate anchored end within the walls vertical reinforcement need walk around the trouble on the girder steel edge of a wing, made things convenient for construction; Can be respectively applied for concrete big or small cross sections and connect beam.

The purpose of the utility model realizes through following technical scheme:

The steel plate concrete shear wall that is abound with peg connects beam; Form by the vertical muscle of Lian Liang, company's beam stirrup, company's beam concrete, steel plate, peg; The described steel plate concrete shear wall that is abound with peg connects beam, for the built-in peg steel plate concrete that is abound with connects beam and concrete shear force wall node building or the structure as joint structure.

Connect in the beam at the ordinary concrete shear wall, add the steel plate that is abound with weld stud that calculates according to designing requirement and get final product.

The advantage and the effect of the utility model are:

1. because the steel plate that adopts belongs to plane institution movement, remove the trouble that the interior vertical reinforcement of steel plate anchored end shear wall need be walked around the steel I-beam edge of a wing from, made things convenient for construction;

2. reduce shaped steel test specimen manufacture difficulty, be convenient to factory process;

Since steel plate thickness with highly can change, connect beam applicable to concrete big or small cross sections;

4. connect beam with the i shaped steel concrete and compare, can reduce steel using amount, save steel.

The specific embodiment

Below in conjunction with figure the utility model is elaborated.

Shear wall is a main lateral resistant member high-rise and super highrise building, is made up of wall horizontal bar 1, the vertical muscle 2 of wall, the concrete 3 of building; Lian Liang is made up of the vertical muscle 4 of beam, beam stirrup 5, the concrete 6 of building; I shaped steel is made up of the peg 9 of the edge of a wing 7, web 8 and welding above that; It is a kind of special shape that steel reinforced concrete connects beam that the steel plate concrete shear wall that is abound with peg connects beam, and the difference that itself and i shaped steel concrete connect beam is to have replaced i shaped steel with steel plate 10.The steel plate that the present invention adopts belongs to plane institution movement, remove from the steel plate anchored end within the walls vertical reinforcement need walk around the trouble on the girder steel edge of a wing, made things convenient for construction; Owing to outside concrete parcel, solved the inside and outside unstability in plane and the fire safety problem of steel plate effectively; Be abound with can guarantee steel plate in the peg of steel plate anchoring with stable, guarantee itself and concrete collaborative work; Since steel plate thickness with highly can change, can be respectively applied for concrete big or small cross sections and connect beam; Height, thickness, ratio of height to thickness, embedment length etc. through the adjustment steel plate can satisfy the various structure designing requirement.This kind shear wall of process appropriate design connects beam and can reach very high bearing capacity and ductility, has good practical value, sees Fig. 7～Fig. 9.The utility model is made up of the vertical muscle 4 of Lian Liang, company's beam stirrup 5, company's beam concrete 6, steel plate 10, peg 9; During application; The sectional dimension of Lian Liang, steel plate size, anchorage length and peg quantity, vertical muscle reinforcement ratio, stirrup reinforcement ratio, strength grade of concrete confirm according to engineering actual loading situation, like Fig. 7～shown in Figure 8.
