Abstract
The invention discloses a construction method of a building superstructure in a high-rise steel-concrete mixed structure with few supporting formworks. The construction method is characterized by comprising the following steps of: lifting an H-shaped steel beam; then selecting appropriate wooden wedges according to the bottom elevation of a floor and the height of the H-shaped steel beam, and paving a key keel on the wedge; placing sub-keels on the surface of the key keel along a direction perpendicular to the key keel; paving bamboo glued plates on the sub-keels along plate joints in the arrangement direction of the sub-keels, and fixing by using the wooden wedges, wherein the elevation of the bamboo glued plates keeps consistent to the upper elevation of the H-shaped steel beam; before concrete is poured, arranging a middle supporting part by adopting a steel pipe and a screw, and measuring the elevation of the bamboo glued plates by using a gradienter in the supporting process; and after the elevation meets the requirements, arranging a middle supporting part used for reinforcing and fixing the key keel and the bamboo glued plates on the middle position of the bottom of the key keel, and then pouring the concrete. Compared with a full-scaffold formwork supporting system, the invention has the advantages of reducing the usage quantity of steel pipe scaffolds, accelerating the construction speed, reducing the consumption of revolving materials, saving the energy and meeting the requirements on the society for low-carbon economy, ensuring the construction quality of the concrete and obtaining good economic benefits and social benefits.
Description
Technical field
The present invention relates to steel building system construction field, is specifically related to the few support shuttering job practices of a kind of high-rise steel-concrete combination construction floor framing..
Background technology
In recent years, the residential project of high-rise steel-concrete combination construction dwelling house system (post is a steel core concrete column, and beam is the H section steel beam, and superstructure is the cast-in-situ steel reinforced concrete superstructure) is increasing.The architectural feature of this structural system is: (1) room standard width of a room in an old-style house is little, mostly between 3～4.5 meters; (2) depth is also less, generally between 3.6～5.7 meters; (3) floor height is not high yet, generally between 2.8～3.3m; (4) superstructure does not have concrete beam, and the member that transmits load all is the H section steel beam.
China's cast-in-place concrete floor supports the method that generally adopts steel pipe to set up the support of full hall scaffold template and constructs.This job practices scope of application is more extensive, but need set up full hall scaffold, can not multilayer construct simultaneously, and construction speed is slow, takies circulation material, the construction cost height.
Summary of the invention
Deficiency at the prior art existence, technical problem to be solved by this invention is, a kind of influence that is not subjected to lower-layer concrete intensity and builds is provided, need not set up full hall scaffold, reduce the use of circulation material, construction speed is fast, reduces labour intensity, reduces the few support shuttering job practices of high-rise steel-concrete combination construction floor framing of construction cost.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the few support shuttering job practices of a kind of high-rise steel-concrete combination construction floor framing may further comprise the steps:
(1), lifting H section steel beam, select suitable timber wedge according to absolute altitude at the bottom of the floor and H shaped steel depth of beam then, on timber wedge, lay main joist;
(2), in direction perpendicular to main joist, secondary joist go up is placed on its surface;
(3), lay the bamboo offset plate, absolute altitude is consistent on bamboo offset plate absolute altitude and the H section steel beam, and fixes with timber wedge at the plate of secondary joist upper edge secondary joist orientation seam;
(4), before the concreting, adopt steel pipe and leading screw that intermediate supports portion is set, shore in the process with level measurement bamboo offset plate absolute altitude;
(5) after absolute altitude meets the requirements, be provided in the centre position of main joist bottom reinforcing and the fixing intermediate supports portion of main joist and bamboo offset plate, carry out concreting afterwards.
The few support shuttering job practices of above-mentioned high-rise steel-concrete combination construction floor framing has additional the double sided foam adhesive tape that prevents spillage at the plate seam of secondary joist vertical direction.
The few support shuttering job practices of above-mentioned high-rise steel-concrete combination construction floor framing, described intermediate supports portion comprises steel pipe, and leading screw is set in steel pipe, steel pipe is provided with the feed nut that matches with described leading screw.
The advantage of the few support shuttering job practices of the high-rise steel-concrete combination construction of the present invention floor framing is:
1) economic effect.The present invention compares with a full hall scaffold form bracing system, has reduced the usage quantity of steel pipe scaffold, and speed of application is fast, uses this patent cost and sets up full hall scaffold method and compare every square metre of cost and can reduce by 3.15 yuan.
2) duration effect.Since do not need to set up full hall scaffold, the influence that is not subjected to lower-layer concrete intensity and builds, and construction speed is fast, does not have layer can save 1 day duration.
3) energy-conservation and environmental protection.This programme reduces the use of circulation material in implementation process, energy conservation meets society's requirement economic to " low-carbon (LC) ", also reduces the noise pollution of work progress simultaneously, avoids occupying large space, improves the integrated environment of job site, energy-conserving and environment-protective.
4) value of applying.Adopt this programme to solve to set up full hall scaffold and cause the difficult problem that finished product increases, the duration increases, and quick construction, convenience, safe and reliable, guarantee workmanship, to increase work efficiency, the reduction engineering cost has higher popularization and application values.Along with the continuous development of society, high-rise steel-mix the structure residential project to get more and more, using few supporting template system can effectively increase construction speed, reduces construction cost, and can guarantee the Concrete Construction quality, produces good economic benefit and social benefit.
