Problems solved by technology

The concrete truss laminated slab of this structure needs to ensure that the thickness of the concrete bottom slab is above 60mm, otherwise the bottom slab will be distorted and cannot meet the rigidity requirements of the laminated slab during the construction process, and the greater the thickness of the concrete bottom slab, the greater its self-weight , thereby increasing the self-weight of the ove...

Embodiment Construction

[0021] A prestressed concrete truss laminated slab according to the present invention includes a concrete floor 10, a truss is arranged on the concrete floor 10, and the truss includes an upper chord 1, and a first web 2 and a second web are respectively arranged on both sides of the upper chord 1 3. Both the first web 2 and the second web 3 are continuously bent steel bars. The top bending parts of the first web 2 and the second web 3 are connected with the outer wall of the upper chord 1. The first web 2 and the second web The bent part of the bottom of the second web bar 3 is pre-embedded into the interior of the concrete floor 10. A plurality of prestressed longitudinal bars 4 are arranged inside the concrete floor 10. The length direction of each prestressed longitudinal bar 4 is parallel to the length direction of the upper chord 1. The concrete floor 10 1-5 transverse steel bars 5 are arranged inside each end, and the length direction of each transverse steel bar 5 is pe...

Abstract

The invention relates to a pre-stressed concrete truss composite slab and a manufacturing method thereof. The pre-stressed concrete truss composite slab comprises a concrete base plate. A truss is arranged on the concrete base plate. The truss comprises an upper chord, first webs and second webs are respectively arranged on two sides of the upper chord, the first webs and the second webs are continuously-bent reinforced steel bars, and the top bent parts of the first webs and the second webs are connected with the outer wall of the upper chord. When hoisting equipment grabs the upper chord for hoisting, the webs, transverse assisting reinforced steel bars and pre-stressed longitudinal ribs are stressed, and the webs are prevented from being stressed independently and falling out of the concrete base plate 10.

Description

technical field [0001] The invention relates to a composite slab of concrete truss for building, in particular to a composite slab of prestressed concrete truss and a manufacturing method thereof. Background technique [0002] In recent years, concrete truss laminated panels have been widely used in the construction industry. This product can reduce the amount of wet work steps and construction formwork and scaffolding in the construction process, reduce labor consumption, reduce construction difficulty, and improve construction efficiency. The existing concrete truss composite slab is prefabricated with a truss composed of upper chords, webs and lower chords. When the concrete floor is poured, the lower chord and part of the webs are embedded in the concrete floor to form a concrete truss composite slab. The lower chord is also used as a concrete The longitudinal inner reinforcement of the base plate. The concrete truss laminated slab of this structure needs to ensure that...
