Description
Technical Field
The invention relates to the field of assembled buildings, in particular to a metal plate and concrete combined chord truss stiffening composite plate and a plane truss used by the same.
Background
The minimum thickness of the bottom plate of the prior prestressed concrete laminated slab generally depends on the sum of the thickness of the reinforcement protection layer and the diameters of the multiple layers of reinforcements. The existing truss lower chord technology for stiffening the prefabricated part of the laminated slab is set to be reinforced with a minimum diameter of 6mm, and in the scheme of forming stiffening ribs by using the planar truss in the prior art, the circular reinforced bar enables the prefabricated part of the laminated slab to not stand and topple over when being produced, namely the planar truss cannot be kept stable and topple over when the bottom plate is poured, and external assistance is needed.
When a single reinforcing steel bar is adopted for reinforcing the concrete upper chord rib, the rib has a certain width, so that the concrete rib is easier to crack.
How to minimize the thickness of the bottom plate and how to solve the cracking of the upper chord concrete rib is the problem to be solved by the invention.

This summary is not an extensive overview of all contemplated aspects, and is intended to neither identify key or critical elements of all aspects nor delineate the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that is presented later.
An object of the present invention is to reduce the plate thickness of a pre-stressed laminated slab floor, thereby reducing the weight of the prefabricated part.
The two purposes of the invention are to facilitate the single-row truss (or plane truss) to keep stable and stand when the prefabricated part is poured.
To this end, the invention provides a composite chord truss stiffening composite slab of metal plate and concrete, comprising:

Preferably, the wave web member group comprises a continuously formed wave steel tube.
Preferably, the wave crests of the wave-shaped steel pipes are flat, and/or the wave troughs of the wave-shaped steel pipes are flat; the flat wave crests are welded on the middle connecting plate, and the flat wave troughs are welded on the lower chord.

The above technical scheme alone or in combination shows the following beneficial effects:
the metal truss is composed of steel pipe web members and steel plate chords which are easy to be unstable outside the surface under compression, and the metal truss is buried in concrete, so that a new stiffening laminated slab with a thinner bottom plate is formed. The upper chord connected with the web member adopts a metal plate instead of a steel bar, so that the upper chord can be prevented from cracking by a small steel amount, and the concrete rib (such as 100mm in width) is easy to crack due to the fact that the upper chord adopts one steel bar in common practice; or, when the lower chord connected with the web member adopts the steel bar, the diameter of the steel bar is not less than 6mm, so that the thickness occupied by the steel bar is larger, the thickness of the steel bar protection layer is smaller at the lower chord, the precast slab is easy to crack at the weak position when being subjected to transverse load, and after the metal plate is added, the metal plate has larger width relative to the steel bar, and the occlusal surface of the metal plate and the concrete is wider, so that the cracking resistance of the precast floor concrete can be increased. Meanwhile, the typical thickness of the metal plate is smaller than 2mm, and the thickness of the metal plate is reduced by more than 2/3 relative to that of the steel bar, so that the thickness of the steel protective layer is increased, the thickness of the lower chord protective layer is increased, and the cracking resistance of concrete at the lower part of the steel is better.
The metal plate can adopt a steel wire mesh plate, and has thinner thickness and better bonding capability with concrete relative to the steel bars.
The invention also provides a plane truss for the stiffening superimposed sheet of the metal plate and concrete combined chord member truss, which is characterized by at least comprising a lower chord, a wave web member and an upper chord, wherein the wave trough of the wave web member is fixed on the lower chord, the lower chord is embedded in the concrete bottom plate of the superimposed sheet, and the wave crest of the wave web member is fixed on the upper chord; at least one of the lower chord and the upper chord is implemented as a metal plate structure.

When the upper chord 31 is a metal plate structure, the bonding strength requirement and the protective layer thickness of the upper chord 31 in the precast concrete rib 2 are considered. The upper chord 31 is preferably a slotted plate with its notch facing the wave web member 33. The trough plate comprises a middle connecting plate 311 and two corner plates 312, wherein the two corner plates 312 are respectively arranged on two sides of the middle connecting plate 311, and the wave crests are connected with the middle connecting plate 311.
