Abstract

The utility model discloses an upper suspension hoisting type hoisting device for reinforced concrete floor construction. The hoisting device comprises a pillar, a suspension beam, hoisting screws and a keel. The lower end of the pillar is fixed on a steel structure beam, the upper end of the pillar is connected with the suspension beam, the hoisting screws are arranged in the length direction of the suspension beam, the lower ends of the hoisting screws are connected with the keel, a template is paved on 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 required, 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. The hoisting device is mainly used for high-rise buildings with large floor height.

Description

The hanging erecting by overhang of suspention is used in reinforced concrete floor construction
technical field:
The utility model belongs to architectural engineering construction technique field, is specifically related to a kind of reinforced concrete floor construction and uses the hanging erecting by overhang of suspention.
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, in the time of construction, can adopt the template of profiled sheet as 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, solve the problem of reinforced concrete floor cast-in-site difficulty in a kind of new construction method of the realm of building construction continuation.
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 construction to use the hanging erecting by overhang of suspention, it is taking the girder steel of building structure or steel truss as basis, on girder steel or steel truss, 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:
The hanging erecting by overhang of suspention is used in a kind of reinforced concrete floor construction, wherein: comprise pillar, suspention beam, hanging screw mandrel and keel, described pillar lower end is fixed on steel structure girder, the upper end of pillar is connected with suspention beam, length direction along suspention beam is provided with hanging screw mandrel, the lower end of hanging screw mandrel is connected with keel, is equipped with template on keel, and template holds out against steel structure girder.
Further, described pillar upper end arranges adjustable jack, and pillar upper end is connected by adjustable jack with suspention beam.
Further, the end face of described template and the end face of steel structure girder are concordant.
Further, described pillar lower end and steel structure girder are welded and fixed, or are fixed with mandrel on steel structure girder, and pillar is sleeved on outside mandrel.
The beneficial effects of the utility model are:
1, the utility model is taking the girder steel of building structure or steel truss as basis, on girder steel or steel truss, 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 building, taking 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, in the utility model, be that pillar is set on steel structure girder, shore supports suspention beam, suspention beam hung formwork, the utility model mainly uses in the time that building storey height is higher.
brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the hanging erecting by overhang of suspention is used in a kind of reinforced concrete floor construction, on steel structure girder 1, erecting by overhang is set, erecting by overhang hung formwork 2, then carry out reinforcing bar binding, concrete pouring construction, when concrete strength reaches after strength of mould stripping, remove erecting by overhang and template 2, complete on-the-spot reinforcing bar and change solidifying Tulou plate construction operation.Described erecting by overhang comprises pillar 3, suspention beam 4, hanging screw mandrel 5, main joist and secondary joist, described pillar 3 lower ends are fixed on steel structure girder 1, pillar 3 upper ends arrange adjustable jack 7, pillar 3 upper ends are connected by adjustable jack 7 with suspention beam 4, be provided with hanging screw mandrel 5 along the length direction of suspention beam 4, the lower end of hanging screw mandrel 5 is connected with keel 6, is equipped with template 2 on keel 6, the end face of template 2 is concordant with the end face of steel structure girder 1, and template 2 holds out against steel structure girder 1.Described pillar 3 lower ends and steel structure girder 1 are welded and fixed, and described keel 6 can be made up of shaped steel, also can be made up of the lumps of wood.
When use, after erecting by overhang of the present utility model is set up on steel structure girder 1, by regulating adjustable jack 7 to adjust the height of suspention beam 4, after completing, in template 2, carry out the operation of present fluid concrete floor.
The present embodiment is applicable to the building operations that floor height is higher, the building operations such as railway station, exhibition hall.
Be noted that, the above embodiment is explanation to technical solutions of the utility model and unrestricted, other amendment 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.
