Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings, but not limited thereto.

[0023] Such as figure 1 As shown, a kind of embedded shear connector of prestressed concrete laminated slab with steel web includes several rectangular steel sheets 1 and steel web 2, and the rectangular steel sheet 1 is welded on the upper and lower sides of steel web 2, and The steel web 2 is vertical; the distance between the rectangular steel sheets 1 is 100 mm; the connection between the rectangular steel sheets 1 and the steel web 2 is laser welding. The steel web 2 is a straight steel web.

[0024] Such as figure 2 As shown, a kind of embedded shear connector of prestressed concrete laminated slab with steel web includes several rectangular steel sheets 1 and steel web 2, and the rectangular steel sheet 1 is welded on the upper and lower sides of steel web 2, and The steel webs 2 are vertical; the distance between the rectangular s...

Abstract

The invention relates to an embedded shearing resistant connector for steel web prestress concrete slab-composite slab, which comprises a plurality of rectangular steel sheets and steel webs (the shapes of the steel webs are various), wherein the rectangular steel sheets are welded onto the upper sides and the lower sides of the steel webs and are vertical to the steel webs; the rectangular steel sheets are welded to the steel webs (the welding properly adopts laser welding or arc welding, and carbon dioxide shield welding on the premise of ensuring the quality). According to the invention, the shearing resistant connector effectively plays the role of shearing prevention, the grappling length of the steel webs is effectively increased, the cohesion of concrete of the steel webs is increased, and the separation resistance of the concrete and the steel webs is improved. The connector is convenient to process, quick in welding, automatic in production and very practical for the type of stacking boards, has higher popularization value, is provided with good performance of fatigue resistance, and can resist the action of pull and push.

Description

technical field [0001] The invention belongs to the field of steel-concrete composite structures, and in particular relates to an embedded shear connector of a steel web prestressed concrete composite slab. Background technique [0002] Steel-concrete composite members are load-bearing composite members widely used at present, which can give full play to the compressive strength of concrete and the tensile strength of steel. At present, this composite structure is widely used in bridge structures, building structures, industrial plants and underground structures. But it is rarely used on the floor in the building. [0003] Existing shear connectors applied to corrugated steel web structures are mainly used in "corrugated steel web prestressed concrete box girder structures" and "steel-concrete composite beams". There are mainly two types of connectors: flange type and embedded type. However, in the field of steel web prestressed laminated slabs, such shear connectors are ...
