Description
Technical field
The utility model relates to building field, single supporting mechanism of especially a kind of box girder inner formwork.
Background technique
Box beam is one kind of science of bridge building central sill, and inside is hollow shape, and there are the edge of a wing in top two sides, similar chest, thus
Name.It is common at present to be divided with material, there are mainly two types of, first is that prestressed reinforced concrete box beam, first is that steel box-girder.Wherein, prestressing force
Reinforced concrete box beam is site operation, and other than having longitudinal prestressing, some also set up transverse prestress；Steel box-girder is usually in work
In-site installation is transported to after processing in factory again, there is full steel structure, also there is part plus reinforced concrete pave-load layer.Wherein steel box-girder is called
Ntitorque steel plate box-girder is the common structure type of Large Span Bridges.It is commonly used on the biggish bridge of span.
Currently, domestic mainly use wooden model or steel form to handle to box girder inner formwork.The shortcomings that this method, is: 1, a large amount of wood of buying
Mould.Plank sheathing service life is short, is unable to recycling and reusing, and project longer for box-beam structure purchases a large amount of wooden model and both disappeared
Cost gold also generates a large amount of building wastes.2, wooden model also needs to clear up obsolete material after using.3, steel form is heavier, to machine
The dependence of tool is higher, and mechanical erection is costly.4, punching block generates maintenance cost due to its physical property when using
It is relatively high.5, punching block is used as internal model, due to its heavier-weight, is unfavorable for construction personnel's operation.
Utility model content
Purpose of the utility model is to solve defects of the existing technology, provide a kind of single support of box girder inner formwork
Mechanism.
To achieve the goals above, the technical solution adopted in the utility model is:
A kind of single supporting mechanism of box girder inner formwork, including branch fastener and the support rod being connect with branch fastener, the support
Head include support supporting plate and with the supporting sleeve that connect of support supporting plate, the support rod includes lower support bar and upper support bar,
The end of upper support bar is extend into lower support bar, and lower support bar and upper support bar are equipped with multiple positioning equidistantly arranged
By the positioning pin connection of positioning hole, the junction of lower support bar and upper support bar is equipped with for hole, lower support bar and upper support bar
Binding hoop.
A kind of single supporting mechanism of above-mentioned box girder inner formwork, the support supporting plate pass through in bolt and box beam inside top
Between keel connect.
A kind of single supporting mechanism of above-mentioned box girder inner formwork, the supporting sleeve and support supporting plate are integrally formed.
The middle part of a kind of single supporting mechanism of above-mentioned box girder inner formwork, the support supporting plate is equipped with connector, connector
Two sides are inclined-plane, and the inclined-plane of connector and the end face of centre keel coincide.
The utility model has the following beneficial effects: the support rod of the mechanism includes lower support bar and upper support bar, upper support bar
End extend into lower support bar, lower support bar and upper support bar are equipped with multiple location holes equidistantly arranged, lower support
Bar and upper support bar pass through the positioning pin connection of positioning hole, and the junction of lower support bar and upper support bar is equipped with binding hoop, under
The height of branch fastener can be adjusted between support rod and upper support bar with relative telescopic, is suitble to the intermediate keel in different height space
Support；
The middle part of supporting plate is supported to be equipped with connector, the two sides of connector are inclined-plane, the inclined-plane of connector and intermediate keel
End face coincide, the inclined-plane by connecting both sides of head facilitates the intermediate keel of connection, sliding when preventing intermediate keel from splicing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, a kind of single supporting mechanism of box girder inner formwork, including branch fastener 1 and the support being connect with branch fastener 1
Bar 2, the branch fastener 1 include the supporting sleeve 12 for supporting supporting plate 11 and connecting with support supporting plate 11, and the support rod 2 includes
Lower support bar 21 and upper support bar 22, the end of upper support bar 22 are extend into lower support bar 21, lower support bar 21 and upper support
Bar 22 is equipped with multiple location holes 23 equidistantly arranged, lower support bar 21 and upper support bar 22 and passes through the positioning in location hole 23
The junction of pin connection, lower support bar 21 and upper support bar 22 is equipped with binding hoop 24.
Further, support supporting plate 11 is connected by bolt and the intermediate keel of box beam inside top, supporting sleeve 12 and branch
Bracketing plate 11 is integrally formed.The middle part of supporting plate 11 is supported to be equipped with connector 13, the two sides of connector 13 are inclined-plane 14, connector
Inclined-plane 14 and the end faces of intermediate keel coincide.
The support rod 2 of the mechanism includes lower support bar 21 and upper support bar 22, and the end of upper support bar 22 extend into lower branch
In strut 21, lower support bar 21 and upper support bar 22 are equipped with multiple location holes 23 equidistantly arranged, lower support bar 21 and upper
For support rod 22 by the positioning pin connection in location hole 23, the junction of lower support bar 21 and upper support bar 22 is equipped with binding hoop
24, the height of branch fastener 1 can be adjusted between lower support bar 21 and upper support bar 22 with relative telescopic, is suitble to different height space
Intermediate spine support；
The middle part of supporting plate 11 is supported to be equipped with connector 13, the two sides of connector 13 are inclined-plane 14, the inclined-plane 14 of connector
It coincide with the end face of intermediate keel, the intermediate keel of connection is facilitated by the inclined-plane 14 of 13 two sides of connector, prevent intermediate keel from spelling
Sliding when connecing.
