Description
Technical field
The present invention relates to a kind of assembled light floor and its construction methods, belong to structural engineering field.
Background technique
In more, high-rise steel structure house, profiled sheet-normal concrete composite floor, steel bar girder is mostly used at present
Floor etc..These floors are there are many insufficient, and predominantly on-site wet operation amount is excessive, assembling degree is low, floor is from great etc..This
On the one hand a little defects restrict the development of building industrialization and steel construction assembled architecture, while also influencing building because floor is overweight
The anti-seismic performance of itself.In addition, at present there is cooperateing with for prefabricated board and lightweight skeleton structure in the lightweight composite floor invented
Work problem, and the method for solving the problems, such as this is to configure shearing resistance in the upper surface of framework beam or other positions by welding manner
Key.There are apparent defects for this method: (1) work in cooperation for solving two kinds of materials by shear key is more complicated, it is difficult to
Realize careful design；(2) lightweight skeleton because material it is relatively thin, welding shear key serious damage will cause to thin-walled framework beam, and
And combined effect can also have a greatly reduced quality.
Summary of the invention
First technical problem to be solved by this invention is the status for the prior art, is provided a kind of existing enough
The bearing capacity and collaborative work degree of construct more convenient, steel skeleton and concrete is higher, the higher dress of degree of safety of floor
With formula light floor.
Second technical problem to be solved by this invention is the status for the prior art, provides a kind of above-mentioned assembled
The construction method of light floor.
The present invention solves technical solution used by above-mentioned first technical problem are as follows: a kind of assembled light floor,
It is characterized in that: including
Support frame positioned at lower part, the support frame include: the lateral girder steel connected in a manner of right-angled intersection and longitudinal direction
Girder steel, wherein lateral girder steel is the steel that inner hollow, upper center can be put into aglite with opening, simultaneously by opening
Matter structural body, longitudinal girder steel are inner hollow, upper center with opening while can be put into aglite and two sides by opening
While being respectively provided with the steel structure body of overhanging wing plate, the lower end of the transverse direction girder steel is carried on overhanging wing plate；
Prefabricated board is erected in the hollow space that longitudinal girder steel and lateral girder steel surround, and prefabricated board lower end two sides are carried on
On overhanging wing plate；

It is in the surface of prefabricated board (11)；By bolt (9) by four sides of the first connecting plate (4) respectively with the longitudinal direction of corresponding position
Girder steel (1) is mutually fixedly connected with lateral girder steel (2)；It is matched again with screw rod (6) with nut and realizes the first connecting plate (4), prefabricated
Plate (11) and overhanging wing plate (3) are fastened；
It is placed the second connecting plate (5) in step 5, longitudinal girder steel (1) between any adjacent two lateral girder steel (2), second
The both ends of connecting plate (5) expose to longitudinal girder steel (1), and are respectively at the surface of prefabricated board (11)；By bolt (9) with
Longitudinal girder steel (1) is mutually fixedly connected, and matches with screw rod (6) with nut and to realize the second connecting plate (5), prefabricated board (11) and outside
Wing plate (3) is stretched to be fastened；
Step 6, the aglite (10) that certain altitude is put into longitudinal girder steel (1) and lateral girder steel (2)；
Step 7 finally pours after-pouring concrete or water above prefabricated board (11) and longitudinal girder steel (1) and lateral girder steel (2)
Cement mortar (12), the plane needs after pouring are smooth, to form overall assembled light floor.
