Description

The quick support system of high-rise steel structure house laminated floor slab

Technical field

The present invention relates to the realm of building construction, particularly belongs to the quick support system of high-rise steel structure house laminated floor slab.

Background technology

More than hundred million tons, developed country's steel building area accounts for overall floorage more than 10% to China's steel production capacity surplus, Beautiful, day is more than 40%, and China is less than 5% at present.China is used as the maximum country of construction scope in the world, steel yield, steel Structural construction development potentiality is huge.In the work progress of steel structure building laminated floor slab, operation is supported to be very important one Individual link.

The construction of steel structure building laminated floor slab is typically necessary setting vertical supporting, as steel-structure factory building has area Greatly, the characteristics of story height, some story heights are more than 6 meters.Conventional template is in the form of vertical vertical rod support, and the length of vertical rod Degree is also relatively higher to have unstability risk, therefore there is the deficiencies such as construction cost is high, construction speed is slow, security risk is big.

The girder steel of steel-structure factory building typically adopts H shaped steel, and using its given shape, we can be jacking and crossbeam It is supported on the edge of a wing of H section steel beams, so as to design a kind of quick support system.

The content of the invention

It is an object of the invention to provide a kind of construction cost is low, the fast high-rise steel structure house laminated floor slab of speed of application is fast Fast support system.

The technical solution used in the present invention is:

The quick support system of high-rise steel structure house laminated floor slab, including symmetrical H profile steel beam, bracing frame, precoated plate, the H Section steel beam includes plane 1, lower plane 2, and the vertical face 3 of the vertical direction of the upper plane 1 of connection and lower plane 2;The support Frame includes the U-shaped jacking 4 and crossbeam 5 of regulating height, and the U-shaped jacking 4 of regulating height is positioned on lower plane 2, and crossbeam 5 is put It is placed in the U-lag of U-shaped jacking 4 of regulating height, crossbeam 5 is held out against in upper plane 1 by adjusting the height of U-shaped jacking 4 Bottom surface, precoated plate 6 are laid on crossbeam 5.

The crossbeam 5 is made up of channel-section steel.

Described 5 two ends of crossbeam are supported by the U-shaped jacking 4 of two symmetrical regulating heights respectively.

The present invention is supported on precoated plate on girder steel using the given shape of steel-structure factory building H section steel beams.The support system System is made up of three parts:H section steel beams, bracing frame, precoated plate.Specifically arrange on the bottom wing listrium of Factory Building H section steel beams The U-shaped jacking of adjustable height, every crossbeam two ends are held out against on girder steel top flange plate with the U-shaped jacking of adjustable height respectively, edge Some U-shaped jackings and crossbeam are arranged in girder steel direction, can lay laminated floor slab and pour top concrete after leveling.

Crossbeam holds out against the top flange plate of H section steel beams by the U-shaped jacking of adjustable height, safe and reliable, while also allowing for tearing open Unload, and support system can be made to be applied to the H section steel beams of different size specification.The rigidity of channel-section steel is very big, can bear larger Construction loads, the amount of deflection of precoated plate during being significantly reduced casting concrete as support beam using channel-section steel improve flooring The Forming Quality of plate.

The Advantageous Effects of the present invention are as follows:

(1)U-shaped jacking adjustable-height, high low range scalable 20cm, convenient construction, strong adaptability, while being equipped with different thick The rubber sheet gasket of degree, is conveniently adjusted crossbeam level.

(2)The support system of the present invention, need not set up vertical supporting, save space, while it is higher perpendicular to eliminate floor height To the risk for supporting easy unstability.

(3)The channel-section steel for having used rigidity larger increases the single span of steel building as crossbeam, while precoated plate Amount of deflection it is less, Forming Quality is also more preferable.

(4)After concrete strength reaches form removal requirement, U-shaped jacking is adjusted directly down and can quickly realize supporting removal, Speed of application is improve, the number of turnover is more, reduces cost.

Description of the drawings

Fig. 1 is the structural representation of support system of the present invention.

A-a profiles of the Fig. 2 for Fig. 1.

Specific embodiment

Embodiments of the invention are described in detail with reference to the accompanying drawings.

Referring to accompanying drawing, the quick support system of high-rise steel structure house laminated floor slab, including symmetrical H profile steel beam, bracing frame, Precoated plate, the H profile steel beam include that plane 1 is vertical with the vertical direction of lower plane 2 on plane 1, lower plane 2, and connection Face 3;Support frame as described above includes the U-shaped jacking 4 and crossbeam 5 of regulating height, and the U-shaped jacking 4 of regulating height is positioned over lower putting down On face 2, crossbeam 5 is positioned in the U-lag of U-shaped jacking 4 of regulating height, by adjusting the height of U-shaped jacking 4 by crossbeam 5 Hold out against in 1 bottom surface of upper plane, precoated plate 6 is laid on crossbeam 5.

Crossbeam 5 is made up of channel-section steel, and 5 two ends of crossbeam are supported by the U-shaped jacking 4 of two symmetrical regulating heights respectively.

Existing high-rise steel structure Factory Building laminated floor slab is briefly described, steel-structure factory building laminated floor slab system is general Including support system and superimposed sheet system, said support system is mainly H-shaped girder steel, laterally disposed similar to I-shaped;It is folded Plywood system is the assembled integral floor being formed by stacking by precoated plate and cast-in-situ steel reinforced concrete layer, in work progress, prefabricated Plate needs vertical supporting, the present invention mainly to solve vertical supporting as the permanent formwork of cast-in-situ steel reinforced concrete overlapping layers Problem.

Fig. 1 is one embodiment of the present of invention, and the U-shaped top of adjustable height is placed specifically on the lower plane 2 of H profile steel beam Support 4, crossbeam 5 is placed in the U-lag of U-shaped jacking, by the regulation up and down of U-shaped jacking, crossbeam 5 is held out against the upper of H profile steel beam In plane 1.

The upper edge at 5 two ends of crossbeam can be encased inside the rubber blanket of different-thickness, to realize the leveling of crossbeam.

Along H profile steel beam length direction interval, 50cm places a U-shaped jacking, and the length of crossbeam is less than the span of H profile steel beam 5cm, crossbeam adopt 10# channel-section steels, and notch is downward.

After all crossbeams 5 are installed, you can laying precoated plate 6, top bars concrete is poured.

Treat that cast-in-place concrete intensity reaches form removal requirement, can quickly realize removing crossbeam by adjusting downwards U-shaped jacking, U-shaped jacking and crossbeam can go to subsequent work face week and be continuing with.

Embodiment described above only expresses one embodiment of the present invention, and its description is more concrete and detailed, but and Therefore the restriction to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for one of ordinary skill in the art For, without departing from the inventive concept of the premise, some deformations and improvement can also be made, these belong to the guarantor of the present invention Shield scope.Therefore, the protection domain of patent of the present invention should be defined by claims.
