Abstract
The utility model discloses a lower suspension hoisting type hoisting device for reinforced concrete floor construction. The device comprises a U-shaped part hoisted on the lower portion of a steel structure beam. A square connector is fixed at the bottom of the U-shaped part, a beam penetrates the square connector, columns are evenly arranged along the length direction of the beam, a keel is arranged at the upper ends of the columns, a template is arranged at the upper end of the keel, and the template jacks the steel structure beam. On the basis of a steel beam or a steel truss at the top of a building, the hoisting device is arranged on the steel beam or the steel truss, the template is hoisted through the hoisting device, and cast-in-place concrete construction operation can be facilitated. An all-around scaffold is not adopted, a press steel plate is not required, and the hoisting device is simple in construction and low in construction cost, and does not require a large amount of labor, so that the hoisting device effectively reduces construction cost and shortens the working period.
Description
technical field:
The utility model belongs to architectural engineering construction technique field, is specifically related to a kind of reinforced concrete floor hanging erecting by overhang of lower suspention for construction.
background technology:
Existing building structure adopts " steel truss or girder steel+concrete slab " structural system in a large number, at steel truss or girder steel upper concrete floor, for this architectural structure system, when construction, can adopt profiled sheet as the template of fluid concrete plate, carry out pouring concrete operation; Or the method that adopts full hall scaffold to support concrete blinding is carried out pouring concrete operation.Profiled sheet expense is higher, and profiled sheet mostly is single load bearing plate, can not meet the service condition of profiled sheet in some construction occasion.Adopt full hall scaffold to support concrete blinding expense also higher, especially in the situation that floor floor height is higher, layer as overhead in railway station, reaches the height of 10 meters from the paramount rack-layer of rail layer, need to set up a large amount of scaffolds, construction bothers, long in time limit, labor strength is large.For above-mentioned technical problem, at the realm of building construction, continue the problem that a kind of new construction method solves reinforced concrete floor cast-in-site difficulty.
utility model content:
In sum, in order to overcome the deficiency of prior art problem, the utility model provides a kind of reinforced concrete floor hanging erecting by overhang of lower suspention for construction, it is that to take the steel truss of building structure or girder steel be basis, on steel truss or girder steel, erecting by overhang is set, by erecting by overhang pendent form, thereby facilitate cast-in-place concrete construction operation, do not need to adopt full hall scaffold, also do not need profiled sheet, construction is simple, cost is low, and do not need a large amount of labours, thereby effectively reduce construction cost, reduction of erection time.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of reinforced concrete floor hanging erecting by overhang of lower suspention for construction, wherein: comprise that hanging is at U-shaped of steel structure girder bottom, U-shaped bottom is fixed with square tube, crossbeam is installed in square tube, length direction along crossbeam is evenly provided with column, column upper end is provided with keel, and keel upper end is provided with template, and template holds out against steel structure girder.
Further, be provided with U-shaped cover plate on described crossbeam, column and U-shaped cover plate are welded and fixed, or U-shaped cover plate upper end is fixed with mandrel, and upright post sleeve is contained in outside mandrel.
Further, between described column and keel, be provided with adjustable jack.
Further, described steel structure girder bottom is hung with two U-shaped of being oppositely arranged, and two U-shaped clamps steel structure girder by split bolt.
The beneficial effects of the utility model are:
1, the utility model is that to take the girder steel of building structure or steel truss be basis, on steel truss or girder steel, erecting by overhang is set, by erecting by overhang pendent form, thereby facilitate cast-in-place concrete construction operation, do not need to adopt full hall scaffold, do not need profiled sheet yet, construction is simple, and cost is low, and does not need a large amount of labours, thereby effectively reduce construction cost, the reduction of erection time.
2, construction method of the present utility model is novel, utilizes cleverly the steel structure girder of fabric structure, take steel structure girder as support, sets up the template of using for fluid concrete, can effectively solve the problem of reinforced concrete floor cast-in-site difficulty.
3, the utility model is at steel structure girder bottom suspended cross-beam, and column is set on crossbeam, and by upright supports template, this kind of structure mainly used in the situation that building storey height is not high.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A of the utility model Fig. 1 is to structural representation;
Fig. 3 is that the B-B of the utility model Fig. 1 analyses and observe intention.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of reinforced concrete floor hanging erecting by overhang of lower suspention for construction, comprise that hanging is at U-shaped 2 of steel structure girder 1 bottom, U-shaped 2 bottoms are fixed with square tube 3, crossbeam 4 is installed in square tube 3, along the length direction of crossbeam 4, is evenly provided with column 5, and column 5 upper ends are provided with keel 6, keel 6 upper ends are provided with template 7, and template 7 holds out against steel structure girder 1.On described crossbeam 4, be provided with U-shaped cover plate 8, U-shaped cover plate 8 upper ends are fixed with mandrel 9, and column 5 is sleeved on outside mandrel 9.Between described column 5 and keel 6, be provided with adjustable jack 10.Described steel structure girder 1 bottom is hung with 2, two U-shaped 2 of two U-shaped of being oppositely arranged and clamps steel structure girders 1 by split bolt 11.Described crossbeam 4 is comprised of two channel-section steels.Described keel 6 can be comprised of shaped steel, also can be comprised of the lumps of wood.
The present embodiment is applicable to the construction of the building that floor height is not high, as office premises, the typical floor floor heights such as office premises are generally 3.6～4.5 meters, floor height is relatively not high, fairly simple in the operation of lower floor laminate face, therefore girder can be arranged on floor face below, facilitates like this operations such as floor bar colligation, concreting
Be noted that, the above embodiment is to the explanation of technical solutions of the utility model and unrestricted, other modification that is equal to replacement or makes according to prior art of affiliated technical field those of ordinary skill, as long as do not exceed thinking and the scope of technical solutions of the utility model, within all should being included in the desired interest field of the utility model.
