Description

A kind of prefabricated large span laminated floor slab
Technical field
The utility model relates to construction engineering technical field, particularly relates to a kind of prefabricated large span laminated floor slab.
Background technology
At present, the floor form of domestic employing has cast-in-situ floor and precast floor slab, and cast-in-place construction technology has a lot of weak point, such as easily prolong and drag the construction period, it is loaded down with trivial details that die process is propped up in job site, produces building waste in a large number, and other uncontrollable additional economic input etc.; Although and precast plate is easier to the industrialization realizing structure, globality is poor, is unfavorable for antidetonation, impervious poor.Superimposed sheet be then first prefabricated after be transported to job site again and build shaping, superimposed sheet can have the advantage of both Bars In Poured Concrete Slab and precast plate concurrently, but common superimposed sheet entirety is heavier, is unfavorable for constructing, and cost of production is higher.
Utility model content
Problem to be solved in the utility model is: common superimposed sheet entirety is heavier, and be unfavorable for transport construction, superimposed sheet preformed layer is fixed or the general integrated setting of pre-buried article, and be inconvenient to operate, form of construction work is single dumb, and cost of production is higher.
The technological means of employing of the present utility model is: a kind of prefabricated large span laminated floor slab, bottom is concrete layer, it is steel mesh reinforcement block above concrete layer, steel mesh reinforcement block is connected with concrete layer by longitudinal vertical truss with ribbing, accommodating one group of hollow loss of weight light plastid in the space between each truss with ribbing; Cast-in-situ concrete layer is set above steel mesh reinforcement block, the coated truss with ribbing of this cast-in-situ concrete layer and hollow loss of weight light plastid.Each organizes hollow loss of weight light plastid is that the hollow loss of weight lightweight monomer longitudinally arranged is arranged in a combination, and this hollow loss of weight lightweight monomer is two or more.
The utility model laminated floor slab has the following advantages: the lightweight loss of weight part inlayed between preformed layer and in-situ layer makes the overall weight loss effect of this laminated floor slab obvious, is beneficial to building operations, and the application of lightweight loss of weight part can save material minimizing cost of production.This lightweight loss of weight part is firmly arranged on preformed layer concrete, and can arrange quantity and the arrangement mode of lightweight loss of weight part as required flexibly, makes it in construction according to the convenient design of the specific requirement of floor.Especially, adopt the form of hollow loss of weight lightweight combination of monomers, make this hollow loss of weight lightweight monomer more convenient in installation and transportation, reduce manufacture difficulty.The truss fabrication with ribbing that preformed layer is arranged is simple, and makes the longitudinal stress rigidity of floor large at the rib reinforcement bar of longitudinal direction, and bearing capacity is large, can realize large span and install.
The utility model laminated floor slab adopts prefabricated and cast-in-place combination, and improve the overall performance of floor, the making of preformed layer can complete in workshop, shortens construction period, decreases die process and a building waste; In-situ layer adopts cast-in-situ concrete mode, can improve anti-crack ability and the bidirectional stress performance of floor, and the concrete in preformed layer and in-situ layer can select different model, flexibly and easily.

Detailed description of the invention
As Figure 1-3, a kind of prefabricated large span laminated floor slab of the utility model, bottom is concrete layer 3, it is steel mesh reinforcement block 4 above concrete layer 3, steel mesh reinforcement block 4 is connected with concrete layer 3 by longitudinal vertical truss 5 with ribbing, accommodating one group of hollow loss of weight light plastid 2 in the space between each truss 5 with ribbing;
Cast-in-situ concrete layer 1 is set above steel mesh reinforcement block 4, the coated truss 5 with ribbing of this cast-in-situ concrete layer 1 and hollow loss of weight light plastid 2.
As shown in Figure 1, this each to organize hollow loss of weight light plastid 2 be that the hollow loss of weight lightweight monomer 21 longitudinally arranged is arranged in a combination, and this hollow loss of weight lightweight monomer 21 is two or more.
When implementing the utility model, after first fixing steel form according to drawing requirement in production department die station, put into the steel mesh reinforcement block that colligation is good, steel mesh reinforcement block connects truss with ribbing.Put into cushion block and after other need pre-buried article, cast preformed layer concrete, fully vibrates, and the bubble of discharging in concrete forms concrete layer.Put into some hollow loss of weight lightweight monomers afterwards and fix, to form hollow loss of weight light plastid, and being fixed in the space between each truss with ribbing.Reach after lifting intensity through maintenance and install, cast-in-place concrete forms cast-in-situ concrete layer, thus completes structure of the present utility model.
The beneficial effects of the utility model are:
The hollow loss of weight laminated floor slab of prefabricated large span, employing Ribbed Bar truss, longitudinal stress rigidity is strong, bearing capacity large, can realize large span, and effectively alleviate deadweight.
Can concreting at the scene, make the anti-crack ability between plate and plate, and bidirectional stress performance is improved.
Be convenient to Workshop Production, thus shortening production cycle, reduce die process and a building waste, reduce costs.
The hollow loss of weight laminated floor slab of prefabricated large span is from heavy and light, and inner light-duty reinforcing bar truss fabrication is simple, saves material, environmental protection.
Effectively can be combined with body of wall, realize the holistic resistant behavior of the preformed layer of prefabricated large span hollow loss of weight laminated floor slab, hollow loss of weight layer and in-situ layer.
