Abstract
The utility model discloses a composite floor which comprises a precast slab. The precast slab comprises a closed profiled steel sheet or more than two closed profiled steel sheets connected end to end. A lightweight aggregate concrete layer is arranged on the closed profiled steel sheets, and the upper surface of the lightweight aggregate concrete layer is a rough surface; a cast-in-situ concrete layer is arranged on the rough surface, and a reinforcing mesh is arranged in the cast-in-situ concrete layer. The composite floor has the advantages that the weight is low, the clear span is large without supporting, temporary supporting is not needed, and economical performance is good. According to the composite floor, the closed profiled steel sheets replace stressed reinforcing bars under the floor, cores of the profiled steel sheets are close to the bottom of the floor, the stress performance is good, and the structure integrity is high; the closed profiled steel sheets replace open profiled steel sheets, and fire and corrosion resistance cost is lower. The composite floor has the advantages that the lower surface of a floor system is flat and attractive, a ceiling is not needed, hanging is convenient, the construction cycle is short, and on-site operation is convenient.
Description
Technical field
The utility model relates to construction engineering technical field, relates in particular to a kind of composite floor.
Background technology
In structure of steel structure building, building cover structure adopts composite deck slabs more, the template while adopting profiled sheet as concreting.This floor system has short construction period, and field operation is convenient, and building integral is better than the advantages such as prefabricated assembled flooring.Because floor is applied and had a large capacity and a wide range in steel building, consider the economy of composite floor, the less one-tenth-value thickness 1/10 of the general employing of profiled sheet substrate.Because ordinary concrete deadweight is larger, in concrete gravity outer load, account for very large proportion simultaneously, cause profiled sheet to allow to be conventionally no more than 4m without supporting clear span.In the time that floor span is larger, often need secondary beam or temporary supporting are set, make troubles to construction, and increased construction costs.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of composite floor.
For achieving the above object, a kind of composite floor described in the utility model, comprise a precast plate, described precast plate comprises remain silent profiled sheet or two profiled sheets of remaining silent above and that head and the tail connect mutually, above the described profiled sheet of remaining silent, light weight aggregate concrete layer is set, described light weight aggregate concrete layer upper surface is matsurface; Cast-in-situ concrete layer is set above described matsurface, in described cast-in-situ concrete layer, is provided with steel mesh reinforcement.
Preferably, the concavo-convex difference of described matsurface is more than or equal to 4mm.
Preferably, the both sides of the profiled sheet of remaining silent described in each are respectively provided with overlap edge, and the adjacent profiled sheet of remaining silent is fixedly connected with by overlapping mode.
The beneficial effects of the utility model are:
Composite floor structure described in the utility model have from heavy and light, without support clear span large, without doing the advantage such as temporary supporting, good economy performance.
Composite floor described in the utility model adopts the profiled sheet of remaining silent to replace steel bar stress at the bottom of plate, and at the bottom of the profiled sheet type heart very approaches plate, stress performance is good, and structural integrity is strong; The employing profiled sheet of remaining silent replaces opening profiled sheet, and fire retardant anticorrosion expense is more economized.
Composite floor described in the utility model have superstructure soffit smooth attractive in appearance, without advantages such as furred ceiling, hanging convenience, short construction period, field operation facilitate.
Brief description of the drawings
Fig. 1 is the structural representation of precast plate described in the utility model embodiment;
Fig. 2 is the structural representation of composite floor described in the utility model embodiment;
Fig. 3 is the connection diagram of composite floor and girder steel described in the utility model embodiment.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is further described.
As Figure 1-Figure 2, a kind of composite floor described in the utility model embodiment, comprise a precast plate, described precast plate comprises remain silent profiled sheet or two profiled sheets 1 of remaining silent above and that head and the tail connect mutually, above the described profiled sheet of remaining silent, light weight aggregate concrete layer 2 is set, described light weight aggregate concrete layer upper surface is matsurface 5; Cast-in-situ concrete layer 4 is set above described matsurface, in described cast-in-situ concrete layer, is provided with steel mesh reinforcement 3.The concavo-convex difference of described matsurface is more than or equal to 4mm to ensure precast plate and the collaborative work of cast-in-situ concrete layer.Remain silent described in the each both sides of profiled sheet are respectively provided with overlap edge, and the adjacent profiled sheet of remaining silent is fixedly connected with by overlapping mode.
Be illustrated in figure 3 the connection diagram of described composite floor and girder steel, in the time of the structure of making as shown in the figure, described precast plate is made in factory, be transported to behind scene, hoisted in position, be connected and fixed by peg with girder steel 6, then lay steel mesh reinforcement, concreting just can form floor structure as shown in Figure 3.
Composite floor structure described in the utility model have from heavy and light, without support clear span large, without doing the advantage such as temporary supporting, good economy performance.
Composite floor described in the utility model adopts the profiled sheet of remaining silent to replace steel bar stress at the bottom of plate, and at the bottom of the profiled sheet type heart very approaches plate, stress performance is good, and structural integrity is strong; The employing profiled sheet of remaining silent replaces opening profiled sheet, and fire retardant anticorrosion expense is more economized.
Composite floor described in the utility model have superstructure soffit smooth attractive in appearance, without advantages such as furred ceiling, hanging convenience, short construction period, field operation facilitate.
Above; it is only preferred embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
