Abstract
The utility model discloses a movable support sleeve structure for a main beam of a building mould board bracket, and is characterized in that the movable support sleeve structure comprises a support sleeve main body; the support sleeve main body made of a rectangular steel pipe can be in sleeve joint with a telescopic beam in a sliding manner; plug-in connection groove structures are arranged on two sides of the support sleeve main body; each plug-in connection groove structure comprises a transversal slot board and a vertical plug-in board; the transversal slot board is arranged transversely; the lower end side of the transversal slot board is fixed on one side wall of the support sleeve main body; the vertical plug-in board is arranged vertically; one vertical side of the vertical plug-in board is fixed on one side wall of the support sleeve main body; the vertical plug-in board and the transversal slot board form an L-shaped plug-in groove; and a water leakage hole is formed at the bottom of the structure of the plug-in groove. The utility model has the advantages of high support strength and cheaper implementation cost.
Description
Technical field
The utility model relates to building concrete cast-in-place construction falsework, is specifically related to a kind of girder movable supporting nested structure of construction formwork support.
Background technology
During the building concrete cast-in-place construction, need to adopt falsework, the falsework upper surface is positioned on the same horizontal plane, lays template in the falsework upper end, just above template, carries out the concrete cast-in-situ construction then.Falsework generally comprises the longeron (being girder) of strip; A plurality of longerons are parallel to be provided with; Be connected with the parallel crossbeam (being auxiliary girder) that is provided with between the longeron; Longitudinal and cross beam forms fenestral fabric and the longitudinal and cross beam upper surface is positioned at same horizontal plane, and the longitudinal and cross beam below adopts steel pipe scaffold to support.Defectives such as traditional falsework adopts the flitch bridge joint, but exists assembly unit and building amount big, and support strength is less, and efficiency of construction is lower.So having occurred again in the prior art is the falsework structure of main body with steel.
China patent No. ZL200720101312.7 once disclosed a kind of structure of length-adjustable form assembly support girder; It includes the U-steel girder that notch is provided with downwards; Below the U-steel girder, be provided with the locknut plate by certain intervals; The corresponding auxiliary girder joint angle type slot plate that on the two sides of U-steel girder, is respectively arranged with the locknut plate is characterized in that, in girder, is equipped with the downward U-steel extensible canopy of a notch with the girder plug-in mounting; On extensible canopy, be equipped with the movable supporting cover of being made up of girder pipe nipple, locknut plate and the angle type slot plate of same specification, it places the movable supporting cover in the outside to be fixed in the outboard end of extensible canopy.The main beam structure of this patent; The employing U-steel obtains, and support strength is better, simultaneously the girder of form assembly support is arranged to the adjustable in length structure; Go for the combination of different width dimensions falsework, and have characteristics simple in structure, easy to adjust.
But the movable supporting nested structure in this existing girder, it is similar with the girder agent structure, and its support set main body adopts the downward U-steel of notch, is provided with the locknut plate below the support set main body, has the defective that intensity is relatively poor, cost is higher.
The utility model content
To the deficiency of above-mentioned prior art, the utility model technical problem to be solved is to provide a kind of intensity higher, the construction formwork support girder movable supporting nested structure that cost is more cheap.
In order to solve the problems of the technologies described above, adopted following technical scheme in the utility model:
A kind of construction formwork support girder movable supporting nested structure is characterized in that, comprises the support set main body that is formed by rectangular steel pipe, and the support set main body is used for slidably that socket is arranged on extensible canopy, and support set main body both sides are provided with the inserting groove structure.Said girder movable supporting cover can be movable girder pipe nipple again.
In the present technique scheme,,, improved construction formwork support integrated support intensity downwards so the intensity of the U-steel that strength ratio available technology adopting notch is provided with is better because the support set main body adopts rectangular steel pipe to obtain.Wherein rectangular steel pipe can directly be bought and obtain, and has cancelled the structure of locknut plate simultaneously, and its cost is more cheap.Because in the prior art; The locknut plate that adopts is to be used for being connected with the steel pipe scaffold that is positioned at the below; But the effect of locknut plated construction was little when the applicant found practice of construction, so usually abandon, adopted the steel pipe scaffold upper end that the holder of scalable U type is set in addition and connected girder.So cancelled the structure of locknut plate in the present technique scheme, reduced manufacturing cost.
Inserting groove structure described in the technical scheme; Can adopt following optimizing structure; Said inserting groove structure comprises that the lower end side of a horizontally set is fixed in the lateral insert plate of support set body wall; Also comprise a vertical vertical plugboard that is provided with, a vertical side of vertical plugboard is fixed in the support set body wall and forms the inserting groove of " L " shape with the lateral insert plate.After optimizing like this, better to the grafting fixed effect of auxiliary girder.But during practical implementation, also can adopt the inserting groove structure that only obtains by a lateral insert plate.
As the further optimization of inserting groove structure, the bottom of said inserting groove structure also is provided with leaking hole.Like this, can avoid forming ponding in the inserting groove, cause the corrosion of steel junction, and then reduce bonding strength, stay potential safety hazard.
In sum, than prior art, the utility model construction formwork support girder movable supporting nested structure has the support strength height, the advantage that implementation cost is more cheap.
Description of drawings
Structural representation when Fig. 1 is the utility model practical implementation.
Fig. 2 is the A-A view of Fig. 1.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment structure of the utility model is done further to specify.
During practical implementation; As depicted in figs. 1 and 2, a kind of construction formwork support girder movable supporting nested structure comprises the support set main body 1 that is formed by rectangular steel pipe; Support set main body 1 is used for socket slidably and is arranged on extensible canopy 2, and support set main body 1 both sides are provided with the inserting groove structure.Said inserting groove structure comprises that the lower end side of a horizontally set is fixed in the lateral insert plate 3 of support set main body 1 sidewall; Also comprise a vertical vertical plugboard 4 that is provided with, a vertical side of vertical plugboard 4 is fixed in the support set body wall and forms the inserting groove of " L " shape with the lateral insert plate.The bottom of said inserting groove structure also is provided with leaking hole 5.
This specific embodiment should be regarded as further specifying rather than limiting the utility model; Can also make all equivalent variations during practical implementation; During such as practical implementation, said inserting groove structure can also only be obtained by a lateral insert plate, should be regarded as still falling into the utility model protection domain.
