A prestressed laminated slab member

A laminated board and prestressing technology, applied in building components, floor slabs, building structures, etc., can solve the problems of lowering floor height clearance, complex cast-in-place process, and large amount of steel bars, so as to reduce self-weight, firm overall structure, and reduce cross-section. The effect of a large moment of inertia

Problems solved by technology

The common disadvantages of all kinds of laminated plate components are that the overall rigidity is low, the overall compressive resistance is low, cracking is easy to occur, the span is small, the weight is large, and the amount of steel bars is large, especially the weight of the bottom plate is heavy, and the thickness must reach 60mm- 80 mm, resulting in correspondingly larger structural components such as beams, columns, walls, foundations, etc., reducing the floor height and headroom, and complicating the cast-in-place process during on-site construction, etc.

Embodiment Construction

[0007] The present invention will be further described with reference to the accompanying drawings.

[0008] 3 in the figure is the bottom plate. At least one row of steel bar trusses is arranged on the bottom plate 3. The steel bar trusses are composed of concrete ribs 1, first steel bars 7 and second steel bars 2. One end of the first steel bar 7 and one end of the second steel bar 2 are connected to the concrete ribs respectively. The rib 1 is connected, the other end of the first steel bar 7 and the other end of the second steel bar 2 are respectively connected with the bottom plate 3, the first steel bar 7 and the second steel bar 2 are parallel in the length direction, and the first steel bar 7 is bent into several lengths along the length direction. A first oblique aid 8 and several second oblique aids 9, a first included angle α is set between the first oblique aid 8 and the second oblique rib 9 1 , the first included angle α 1 is an acute angle, the second steel bar ...

Abstract

A pre-stressed composite slab component comprises a base plate. At least one row of steel bar trusses is arranged on the base plate. The steel bar trusses comprise concrete ribs, first reinforced steel bars and second reinforced steel bars, one ends of the first reinforced steel bars and one ends of the second reinforced steel bars are respectively connected with the concrete ribs, the other ends of the first reinforced steel bars and the other ends of the second reinforced steel bars are respectively connected with the base plate, and the first reinforced bars and the second reinforced steel bars are parallel in the length direction. The pre-stressed composite slab component has the advantages that the component is good in overall structure stability, high in pressure resistance, firm in overall structure, free of deformation, and the like; the base plate can be made within 30mm, the self-weight is greatly reduced by 50% while the weight of a beam, a column, a wall and a basic component is reduced, and the head room of a building story is increased.

Description

technical field [0001] The invention relates to a building component, which is a prestressed laminated plate component. Background technique [0002] There are various structures of laminated plate components frequently used in the construction field, which are mainly selected according to the needs of different building forms and different building uses. The common disadvantages of all kinds of laminated plate components are that the overall rigidity is low, the overall compressive resistance is low, cracking is easy to occur, the span is small, the weight is large, and the amount of steel bars is large, especially the weight of the bottom plate is heavy, and the thickness must reach 60mm- 80 mm, resulting in correspondingly larger structural components such as beams, columns, walls, and foundations, which reduces the floor height and headroom, and complicates the cast-in-place process during on-site construction. Contents of the invention [0003] The object of the pres...
