Abstract

The utility model relates to a hollow composition board with a built-in a hollow internal mold, comprising a flat steel plate and the hollow internal mold, wherein the upper surface of the flat steel plate is vertically and fixedly provided with steel plates with transverse opened holes and longitudinal opened holes; the hollow internal mold is fixed on a steel reinforcement welded mesh by iron wires wound on a bolt pin arranged on the surface of the flat steel plate; the steel reinforcement welded mesh is positioned above the steel plates with the opened holes; the flat steel plate, the steel plates with the opened holes, the hollow internal mold and the steel reinforcement welded mesh form a hollow composition plate bracket; and the bracket is poured with concrete. The hollow composition board with the built-in the hollow internal mold has the characteristics of light dead weight, better intensity and stressed performance, simple structure and convenient use.

Description

The hollow combined board of built-in hollow internal mold
Technical field
The utility model belongs to field of civil engineering, relates to building unit, relates in particular to a kind of hollow combined board of built-in hollow internal mold.
Background technology
Used compoboard is generally steel plate-concrete compoboard or hollowcore slab in the civil engineering.The steel plate-concrete compoboard is meant direct concreting on steel plate, make the two in conjunction with closely forming cooperative floor or bridge deck by certain measure then, compoboard does not need formwork and sets up interim support in construction works, it is very convenient to construct, but the deadweight of steel plate-concrete compoboard is too big, and is not too suitable for bridge deck and floor that span is bigger.In the engineering practice,, adopt hollowcore slab, but hollowcore slab intensity and stress performance are relatively poor in order to reduce the deadweight of bridge deck and floor.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of hollow combined board of built-in hollow internal mold, and it is from heavy and light, and intensity and stress performance are better, have characteristics simple in structure, easy to use.
In order to achieve the above object, the technical solution adopted in the utility model is:
The hollow combined board of built-in hollow internal mold, comprise plain plate 1, the horizontal and vertical perforate steel plate 2 of vertical fixing above the plain plate 1, also comprise hollow internal mold 4, the iron wire that twines on the peg 3 of hollow internal mold 4 by plain plate 1 surface setting is fixed on the welded steel fabric 5, welded steel fabric 5 is positioned at the top of perforate steel plate 2, and described plain plate 1, perforate steel plate 2, hollow internal mold 4 and welded steel fabric 5 constitute hollow combined board support, concreting 6 on described hollow combined board support.
Described perforate steel plate 2 is a plurality of.
Described hollow internal mold 4 is a plurality of.
Described hollow combined board is a dual platen, about plain plate 1 symmetry.
The utility model compared with prior art has the following advantages:
1) deadweight is lighter, relative ordinary reinforced concrete solid slab, and deadweight can reduce more than 45%, and plate is thick more, and deadweight reduction amplitude is big more.
2) each member can prefabricatedly be finished, and the scene is used in combination, and both can ensure the quality of products, again reduction of erection time greatly.
3) owing to be welded with the lateral opening steel plate simultaneously and vertically to the perforate steel plate, can effectively improve the rigidity and the intensity of compoboard at horizontal and vertical two orthogonal directions simultaneously, stress performance is good.
4) the bottom plain plate can play template action, has very big rigidity behind burn-on perforate steel plate and the steel pipe, therefore, need not to set up interim support, easy construction.
5) can be designed to Orthogonal Double to same sex plate, more effectively improve supporting capacity.
6) has better shock resistance weight bearing power.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further details.
The utility model is the hollow combined board of built-in hollow internal mold, comprise plain plate 1, the horizontal and vertical perforate steel plate 2 of vertical fixing above the plain plate 1, also comprise hollow internal mold 4, the iron wire that twines on the peg 3 of hollow internal mold 4 by plain plate 1 surface setting is fixed on the welded steel fabric 5, welded steel fabric 5 is positioned at the top of perforate steel plate 2, described plain plate 1, perforate steel plate 2, hollow internal mold 4 and welded steel fabric 5 constitute hollow combined board support, concreting 6 on described hollow combined board support.
For ease of processing, the quantity of described perforate steel plate 2 and hollow internal mold 4 all is plural number.
Simultaneously, the utility model can be designed to Orthogonal Double to same sex plate, more effectively improves supporting capacity, in the other one side of plain plate 1, is the plane of symmetry with plain plate 1 promptly, and perforate steel plate 2, peg 3, hollow internal mold 4, welded steel fabric 5 and concrete 6 are set.
In the utility model, the use of hollow internal mold can be played the advantageous effect that reduces dead load greatly in engineering structures, and is especially obvious for span bigger bridge deck and floor application advantage.Adopt the utility model compoboard of hollow internal mold, it is very light to conduct oneself with dignity, relative ordinary reinforced concrete solid slab, deadweight can reduce more than 45%, and plate is thick more, and deadweight reduction amplitude is big more, simultaneously owing to be welded with the lateral opening steel plate simultaneously and vertically to the perforate steel plate at horizontal and vertical two orthogonal directions simultaneously, can effectively improve the rigidity and the intensity of compoboard, stress performance is good.
Work in-process, plain plate can play template action, has very big rigidity behind the perforate steel plate of burn-oning, and therefore, need not to set up interim support, easy construction.
Compoboard of the present utility model both can be prefabricated, also can be cast-in-place.Most of manufacturing process can be prefabricated in the factory and finish when prefabricated, therefore, both can fine assurance fabricating quality, can shorten the construction period greatly again, have significant advantage, especially the repairing maintenance works for bridge has remarkable meaning more; Plain plate plays the effect of template when cast-in-place, can reduce the use of template, reduces expenses, and the welded steel fabric of Shi Yonging can save the manpower of assembling reinforcement simultaneously, the reduction of erection time, reduces expenses.
The utility model has quite big application prospect in engineerings such as long-span bridge panel, large bay floor, basement roof.
