Abstract
The utility model discloses a demountable reusable floor bearing plate. The demountable reusable floor bearing plate is characterized in that a coated steel sheet is adopted and is formed by coating the upper surface of a galvanized steel sheet with a plastic film, and a steel bar truss is connected with the coated steel sheet through demountable bolt fixing parts. The plastic film is arranged between the galvanized steel sheet and a concrete plate and is connected with the galvanized steel sheet and the concrete plate through the demountable bolt fixing parts, the galvanized steel sheet and the concrete plate can be easily separated in the detaching process, the plastic film can be torn off later, mounting and dismounting in construction are convenient and fast, manufacturing cost is saved, and materials are not wasted. Due to repeated use of the demountable reusable floor bearing plate, the consumed prefabricated materials of construction sites and factories are largely reduced.
Description
Technical field
The utility model relates to a kind of detachable multiplexing floor support plate, is applicable to production and the construction of assembly concrete floor member.
Background technology
Floor type mainly contains hollow prefabricated concrete floor, cast-in-place concrete floor, composite deck slabs, steel bar truss floor support plate etc. at present.Although hollow precast concrete plank speed of application is fast, flooring globality is poor, difficult causing of floor jointing exist leakage problems in use procedure, and because flooring globality is poor, when earthquake, earthquake is serious in addition.Cast-in-place concrete floor good integrity, rigidity is large, stressed good, but wet trade is many when site operation, and reinforcing bar binding is many, long in time limit with operations such as formworks, engineering cost is high and its later stage performance has very large associated with concrete curing condition.Composite deck slabs has been saved the formwork work of cast-in-place concrete floor, and speed of application is fast but distortion is large, expense is high, and the out-of-flatness of plate bottom surface, also needs in addition furred ceiling, and overall expenses is higher.The integral rigidity of steel bar truss floor support plate is good, and speed of application is fast, but in building construction process, the defect that exists some to be difficult to overcome.For the office building that has furred ceiling requirement, engineering finishes rear pattern plate and is difficult to take off, great majority be there is no to the housing construction of furred ceiling requirement, in the time that floor slab tops is plastered, because galvanized steel plain sheet and cast-in-situ concrete have very strong adhesion stress, can only adopt spot welding between manual breakage steel bar girder and galvanized steel plain sheet, the galvanized steel plain sheet that support cast-in-situ concrete is used tears it down.Cause like this galvanized steel plain sheet of taking off to become waste product, can not be taken as again template and repeatedly utilize.In the face of these problems; there is assembling floor support plate; this class floor support plate is in the time of dismounting galvanized steel plain sheet; concrete can not finely separate with galvanized steel plain sheet, and galvanized steel plain sheet often occurs to destroy and large deformation, and steel bar girder is close to galvanized steel plain sheet in addition; thickness of protection tier cannot meet national standard requirement; have a strong impact on use and the long durability of floor, mechanical seaming connects and is difficult for execute-in-place, and expense is large.
Utility model content
The utility model is for avoiding the existing weak point of above-mentioned prior art, the detachable multiplexing floor support plate that provide a kind of easy installation and removal, can recycle.
The utility model adopts following technical scheme for solving the problems of the technologies described above:
The design feature of the detachable multiplexing floor support plate of the utility model is: be covered with plastic sheeting at the upper surface of galvanized steel plain sheet main body and form precoated steel sheet; Steel bar girder is connected with precoated steel sheet by removable bolt retainer.
The design feature of the detachable multiplexing floor support plate of the utility model is also:
Described removable bolt retainer comprises the cushion block of the web ends that is fixedly welded on described steel bar girder, and the built-in screwed hole of cushion block, between described cushion block and described precoated steel sheet, is fastenedly connected by the removable set bolt that runs through described precoated steel sheet.
On described precoated steel sheet, be array through hole is set, described removable set bolt runs through described through hole and is threaded with the cushion block of the web ends of the steel bar girder on correspondence position.
Described removable set bolt is provided with rotary handle at afterbody, and is provided with pad on rotary handle.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model between galvanized steel plain sheet and concrete slab across layer of plastic film, and connect by removable bolt retainer, in unloading process, galvanized steel plain sheet separates with concrete slab is easy, later stage plastic sheeting can tear, construction and installation and convenient disassembly are quick, save cost, do not waste material.
2, the utility model is connected by removable set bolt and cushion block between steel bar girder and precoated steel sheet, mount and dismount easy and simple to handle, galvanized steel plain sheet main body is not fragile, and the rate of recovery is high, is recycled and can significantly be reduced job site and prefabrication consumptive material by it.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the lateral view of Fig. 1;
Precoated steel sheet schematic diagram in Fig. 3 the utility model;
Number in the figure: 1 cushion block, 2 removable set bolts, 3 pads, 4 rotary handles, 5 steel bar girders, 6 plastic sheetings, 7 galvanized steel plain sheet main bodys, 8 through holes.
The specific embodiment
Referring to Fig. 1, Fig. 2, in the present embodiment, detachable multiplexing floor support plate is to be covered with plastic sheeting 6 at the upper surface of galvanized steel plain sheet main body 7 to form precoated steel sheet; Steel bar girder 5 is connected with precoated steel sheet by removable bolt retainer.
As depicted in figs. 1 and 2, in the present embodiment, removable bolt retainer comprises the cushion block 1 of the web ends that is fixedly welded on steel bar girder 5, is that the removable set bolt 2 by running through precoated steel sheet is fastenedly connected between cushion block 1 and precoated steel sheet.
Shown in Fig. 3, in the present embodiment, be array through hole 8 is set on precoated steel sheet, removable set bolt 2 is to run through through hole 8 to be threaded with the cushion block 1 of the web ends of the steel bar girder 5 on correspondence position.
For the ease of dismounting operation, be fixedly connected with rotary handle 4 at the afterbody of removable set bolt 2, and on rotary handle, be provided with pad 3, rotate rotary handle 4, steel bar girder 5 and precoated steel sheet can be fixedly connected take pad 3 as supporting plate.
In this enforcement of tool, detachably that steel bar girder and precoated steel sheet are made respectively with floor support plate repeatedly, then at the construction field (site) with can both being linked together formula bolt retainer, forming a complete steel bar truss floor support plate uses, after cast in place concrete plate maintenance is good, unclamp removable set bolt, then easily galvanized steel plain sheet is taken off, the galvanized steel plain sheet taking off and removable bolt retainer can reuse.Both convenient construction, can save again construction cost significantly.
