Description
Technical Field
The utility model relates to a building field, in particular to make things convenient for superimposed sheet structure that pipeline passed through.
Background
At present, the country is vigorously promoting housing industrialization, and building parts which are cast in the construction site are changed into factory production and then are assembled in the site. This produces the following effects: 1) the pollution of the field garbage to the environment is reduced. 2) After the industrialized production is carried out, a large amount of labor cost is saved.
Due to earthquake resistance, the floor slab cannot be completely prefabricated, and only a laminated slab (namely, the bottom of the floor slab is prefabricated in a factory by 60 mm, and the upper surface of the floor slab is cast in situ by 60 mm) can be adopted. Because the height of the cast-in-place part is only 60 mm, and only 35 mm of net height is left after deducting 25 mm of the upper part (the diameter of the truss top rib is 10 mm and the thickness of the protective layer is 15 mm), when a cross pipeline exists, the cross pipeline cannot penetrate through the bottom of the truss reinforcing steel bar, the thickness of the cast-in-place layer is usually increased, but the construction cost is increased.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a superimposed sheet structure that pipeline passed through truss reinforcing bar bottom, need not increase thick, the building cost is low makes things convenient for the pipeline to pass through.
The purpose of the utility model is realized like this:
a laminated slab structure facilitating pipeline crossing comprises a precast concrete layer, a cast-in-place concrete layer, a steel bar truss and a pipeline, wherein the steel bar truss is fixedly connected to the precast concrete layer, the cast-in-place concrete layer is located above the precast concrete layer, the pipeline is laid on the cast-in-place concrete layer, and the steel bar truss is disconnected corresponding to the pipeline to form a notch.
One of the functions of the steel bar truss is to strengthen the self rigidity of the prefabricated floor slab and prevent the floor slab from cracking in the processes of manufacturing, demoulding, transporting and installing. The steel bar truss has the other function of strengthening the meshing effect of the prefabricated part and the cast-in-place part of the laminated slab, so that the laminated slab and the cast-in-place part are stressed together as a whole, and the meshing effect of the prefabricated part and the cast-in-place part cannot be influenced by locally breaking the truss gluten, so that the prefabricated slab cannot crack when the position of the steel bar truss corresponding to a pipeline is broken, the meshing effect of the prefabricated part and the cast-in-place part cannot be influenced, the problem that a crossed pipeline cannot penetrate through the bottom of the steel bar of the laminated slab truss is solved, the building cost is not increased, and the steel bar truss has a good popularization prospect.
The purpose of the utility model can also adopt the following technical measures to solve:
furthermore, the precast concrete layer is provided with a lower chord rib and a floor bottom rib in the other direction, the lower chord rib and the floor bottom rib in the other direction are arranged on the same plane in a staggered mode to form a net structure, the cast-in-place concrete layer is provided with an upper chord rib, the upper chord rib is parallel to the lower chord rib, a web member is arranged between the upper chord rib and the lower chord rib, the web member, the upper chord rib and the lower chord rib are fixedly connected, and the adjacent lower chord rib, the upper chord rib and the web member form the steel bar truss.
Furthermore, the lower chord rib, the upper chord rib and the web members of the position, corresponding to the pipeline, of the steel bar truss are disconnected.
The utility model has the advantages as follows:
the utility model discloses, one of steel bar truss's effect is firstly to strengthen prefabricated floor's self rigidity, prevents that the floor from ftractureing in preparation, drawing of patterns, transportation, installation, owing to when laying the pipeline, and "preparation, drawing of patterns, transportation, installation" procedure has been accomplished to prefabricated floor, and the bottom sprag has installed in place, can not cause the prefabricated plate fracture with steel bar truss disconnection. The steel bar truss has the other function of strengthening the meshing effect of the prefabricated part and the cast-in-place part of the laminated slab, so that the laminated slab and the cast-in-place part are stressed together as a whole, and the meshing effect of the prefabricated part and the cast-in-place part cannot be influenced by locally breaking the truss gluten, so that the prefabricated slab cannot crack when the position of the steel bar truss corresponding to a pipeline is broken, the meshing effect of the prefabricated part and the cast-in-place part cannot be influenced, the problem that a crossed pipeline cannot penetrate through the bottom of the steel bar of the laminated slab truss is solved, the building cost is not increased, and the steel bar truss has a good popularization prospect.
