Abstract
The utility model discloses a steel and concrete shear connector structure comprising a steel structure, a concrete structure above the steel structure, and a connector for fixedly connecting the concrete structure with the steel structure, wherein the connector comprises a plurality of steel plate bodies which are vertically arranged in parallel, one side of each steel plate body away from the steel structure is provided with a groove, the width of the bottom of the groove is greater than the width of a notch, and the grooves of all the steel plate bodies are aligned with one another, so as to facilitate the arrangement of reinforced ribs. The steel and concrete shear connector structure is convenient in construction, and the steel plate bodies can be molded only by cutting a whole steel plate in machining, so as to avoid steel waste and be economical in manufacturing cost; each reinforced rib can be integrally placed in through the notch, so that the construction is convenient; and the cross section of concrete at the notch is larger than the cross section of the PBL connector, so that the steel and concrete shear connector structure is good in integrity and stronger in anti-shearing capacity.
Description
Technical field
The utility model belongs to civil works building technology field, particularly a kind of steel and concrete shear connector structure.
Background technology
Steel-concrete combined structure is with its whole stressed economy; Bring into play two kinds of materials reasonability of advantage and the outstanding advantage of being convenient to construct separately; Occupy critical role in bridge construction, industry and the civilian construction abroad, also obtained effect more and more widely in China.Shear connector is the critical component of steel-concrete combined structure, and its effect is to prevent the mutual slippage of the two level at the interface and separate, and the steel work and the concrete structure of big difference constitute an integral body and co-operation to make modulus of elasticity have very.The shear connector form has a variety of, and present stage is mainly adopted WELDING STUDS and perforate steel plate connector (PBL connector).The WELDING STUDS construction requirement is high, causes the steel mesh reinforcement difficult arrangement, and concrete is difficult for vibrating solid.The PBL shear connector is a fluid concrete after perforate on the steel plate, utilizes the concrete tenon pass in the hole to resist shear flow, and in steel plate hole, wears steel bar stress and can further improve its bearing capacity.But the PBL shear connector need bore a lot of holes on steel plate, reinforcing bar needs ship to cross the circular hole on the steel plate, and speed of application is slow, and steel plate obviously separates concrete, and concrete should not be constructed and brought into play mass action.
Summary of the invention
The utility model provides a kind of steel and concrete shear connector structure, adopts this structure construction convenience, cost economic and can improve shear resistance between steel and concrete, thereby guarantee the globality of steel and concrete combined structure.
A kind of steel and concrete shear connector structure; Comprise the concrete structure of steel work, steel work top and the connector that both are fixedly connected; Described connector comprises some steel plate bodies of parallel and vertical setting, and the steel plate body is provided with groove away from a side of steel work, and this groove bottom land width is greater than width of rebate; And the groove of every block plate body aligns each other, is convenient to the layout of reinforcing bar.
The bottom land width is arranged reinforcing bar to be implemented in the bottom land both sides, so the width of bottom land and the degree of depth need satisfy the needs that hold the reinforcing bar space greater than width of rebate.The setting of notch makes things convenient for inserting of reinforcing bar, and is simple to operate.Steel plate body and stressed steel work are fixed through welding, in groove, penetrate reinforcing bar, and form steel mesh reinforcement with other reinforcing bar; Behind the concreting; Steel mesh reinforcement is connected the steel plate body with groove inner concrete and shearing and bears the shearing resistance effect jointly, and good integrity receives force intensity big.
For ease of the processing of steel plate body upper groove, in the optimized technical scheme, select the shape of groove identical, and evenly distribute.In the further preferred scheme, described groove is a symmetrical structure, and the difference of the width of bottom land and the width of notch is greater than the double-width of the diameter of reinforcing bar in the concrete structure, to make things convenient for the layout of reinforcing bar.
In addition, for ease of the comprehensive utilization of material, reduce the consumption of steel plate materials, in the optimized technical scheme, described groove is the inverted T-shaped groove.When the degree of depth of selecting described notch and the deep equality of bottom land; And when the width of bottom land equates with adjacent two notch center clear distances, can select to utilize a block plate symmetry to be processed into two identical steel plate bodies, guarantee the comprehensive utilization of whole steel plate; Save material, and easy to process.
Steel of the utility model and concrete shear connector structure, easy construction, the steel plate body adds man-hour as long as whole steel plate is cut just plastic, does not have steel wastes, cost economic; Reinforcing bar can be put into easy construction through whole of notch; The notch concrete is big than PBL connector sectional area, good integrity, and shear resistance is stronger.

The specific embodiment
Shown in Fig. 1～4; A kind of steel and concrete shear connector structure comprise the concrete structure 2 of steel work 1, steel work 1 top and the connector that both are fixedly connected, and connector comprises two block plate bodies 3 of parallel and vertical setting; Steel plate body 3 is provided with groove 4 away from a side of steel work 1; These groove 4 bottom lands 41 width are greater than notch 42 width, and the groove on the two block plate bodies 3 aligns setting each other, are convenient to the layout of transverse reinforcement.
Like Fig. 5 and shown in Figure 6, the process of steel plate body 3 is:
Select suitable steel plate 7 at first according to actual needs, on steel plate 7 according to line of cut shown in Figure 58 blankings, steel plate about in the of 7 symmetry be divided into two block plates, promptly the steel plate body 3, and is as shown in Figure 6.
The process of this embodiment is:
The steel plate body 3 of band groove 4 is welded at desired location with stressed steel work 1; Penetrate horizontal shear reinforcement 5 in the groove 4 in steel plate body 3; And form steel mesh reinforcements with longitudinal reinforcement 6, and build the concrete of combination concrete structure 2, make combining structure form integral body.Reinforcing bar is set in groove, and concreting utilizes interior reinforcing bar of notch and concrete to bear the shearing resistance effect.
