Abstract
The invention discloses a novel hollow composite slab, which comprises a flat steel plate, a plurality of holed steel plates, and a plurality of steel pipes, the holed steel plates are parallel and are vertically welded on one plane of the flat steel plate, the plurality of steel pipes respectively pass through corresponding round holes of the holed steel plate and are welded with the round holes, the flat steel plate, the plurality of holed steel plate, and the plurality of steel pipes combine into a hollow slab support, and the hollow slab support is poured with light aggregate concrete to finally form the steel plate-light aggregate concrete hollow composite slab. The novel hollow composite slab of the invention has light weight, convenient construction, higher strength and rigidity, and better bearing performance, can be widely applied to the bridge slabs of new bridges and house buildings, the basement top board or room floor, and can be also applied to the bridge slab replace and maintenance engineering.
Description
Technical field
The present invention relates to field of civil engineering, specifically is a kind of hollow combined board.
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 more.
Summary of the invention
The purpose of this invention is to provide a kind of from heavy and light but intensity and stress performance novel hollow combined board preferably.
Technical scheme of the present invention is such: a kind of novel hollow combined board, comprise plain plate, plural piece perforate steel plate and complex root steel pipe, above-mentioned each perforate steel plate is erect respectively with paralleling and is welded on the side plane of above-mentioned plain plate, above-mentioned complex root steel pipe is through at respectively in each corresponding circular hole of above-mentioned each perforate steel plate, and above-mentioned complex root steel pipe is connected together with each corresponding circle eyelet welding of above-mentioned each perforate steel plate respectively, above-mentioned plain plate, plural piece perforate steel plate and complex root steel pipe are synthesized a hollowcore slab support, are cast with light weight aggregate concrete on this hollowcore slab support.
Above-mentioned light weight aggregate concrete is to adopt haydite as the formed a kind of concrete of aggregate.
After adopting such scheme, novel hollow combined board of the present invention, form a hollowcore slab support with plain plate, plural piece perforate steel plate and the welding of complex root steel pipe earlier, and then on this hollowcore slab support, pour into a mould light weight aggregate concrete, form steel plate-Hollow Lightweight Concrete Block compoboard.
Novel hollow combined board of the present invention has following beneficial effect:
1, light weight aggregate concrete is to adopt haydite as the formed a kind of concrete of aggregate, ordinary concrete has lighter density relatively, in engineering structures, can play the advantageous effect that reduces dead load greatly, especially obvious for span bigger bridge deck and floor application advantage.Adopt the compoboard of the present invention of light weight aggregate concrete, it is very light to conduct oneself with dignity, 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, because the elongated layout of perforate steel plate of welding adopts steel pipe simultaneously, can effectively improve the rigidity and the intensity of compoboard, stress performance is better.
3, 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;
4, the most of manufacturing process of compoboard of the present invention can be prefabricated in the factory and finish, therefore, promptly 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;
5, because from heavy and light, rigidity is big, intensity is high, this compoboard has quite big application prospect in engineerings such as long-span bridge panel, large bay floor, basement roof;
6, under the appropriate design prerequisite, compoboard of the present invention can be designed to Orthogonal Double to same sex plate, more effectively improves supporting capacity;
7, hollow combined board of the present invention has better advantage in old bridge strengthening maintenance, by changing bridge deck, can make substructure institute bearing load obtain bigger reduction, thereby be equivalent to improve the supporting capacity of old bridge;
8, the relative ordinary concrete height of light weight aggregate concrete fire resistance has fire resistance preferably, has fine advantage in building construction;
9, hollow combined board of the present invention is combined into one steel plate, steel pipe and light weight aggregate concrete, has better shock resistance weight bearing power, is suitable in the underground protective engineering;
10, can also conveniently apply prestressing force in the steel pipe, form pre-stressed steel plate-Hollow Lightweight Concrete Block compoboard.

The specific embodiment
A kind of novel hollow combined board of the present invention, as Fig. 1,2,3,4, shown in 5, comprise plain plate 1, plural number piece perforate steel plate 2 and complex root steel pipe 3, each perforate steel plate 2 is erect respectively with paralleling and is welded on the side plane of plain plate 1, complex root steel pipe 3 is through at respectively in each corresponding circular hole of each perforate steel plate 2, and steel pipe 3 is connected together with each corresponding circle eyelet welding of each perforate steel plate 2 respectively, like this, plain plate 1, plural number piece perforate steel plate 2 and complex root steel pipe 3 just welding are combined to form a hollowcore slab support 4, be cast with light weight aggregate concrete 5 on the hollowcore slab support 4, finally form steel plate-Hollow Lightweight Concrete Block compoboard.Light weight aggregate concrete 5 is to adopt haydite as the formed a kind of concrete of aggregate.
Add man-hour, at first on plain plate 1, weld perforate steel plate 2, then steel pipe 3 is penetrated respectively in the corresponding circular hole in each perforate steel plate 2, and welding closely forms hollowcore slab support 4, and then on hollowcore slab support 4, pour into a mould light weight aggregate concrete 5, form a kind of steel plate-Hollow Lightweight Concrete Block compoboard that is applicable to bridge deck or floor.According to actual needs, the thickness of the Circularhole diameter of the spacing between the thickness of plain plate and perforate steel plate, each perforate steel plate, perforate steel plate and each circular hole spacing and compoboard is determined by computational analysis.During work: steel plate-Hollow Lightweight Concrete Block compoboard is welded on the girder steel, forms the steel-concrete composite beam of band hollow combined board, bear bridge floor load or floor load by steel plate-Hollow Lightweight Concrete Block compoboard.
