Abstract
A kind of formwork-support cross bar for being used to form concrete cast-in-situ wall construction formwork-support, with a pair of relative and arranged in parallel C-type steels of notch, biside plate punishment positioned at a pair of C-type steels between a pair of C-type steels is furnished with the connecting plate being vertically arranged, the lateral surface of the connecting plate is located in the biside plate medial plane of the pair of C-type steel, and each connecting plate is formed by welding one with a pair of described C-type steels；Upper and lower corresponding and shape and size identical hole is distributed with the trough floor of the pair of C-type steel.This formwork-support crossbeam it is reasonable in design, have rigidity is big, in light weight, cost is low, installation it is light the characteristics of.
Description
Technical field
It the utility model is related to building form support frame, and in particular to a kind of formwork-support cross bar.
Background technology
In the concrete cast-in-situ construction of architectural engineering, the template steel support frame formed is combined by steel components, because of it
A large amount of timber can be saved, conveniently builds, ensure the advantages that construction quality, obtain more and more extensive application.Current Building ' wall
The cross bar of body template steel support frame, it is more using the C-shaped steel with reinforcement structure and lightening hole, such as in bottom land plate face and both sides
Plate face is suppressed with the C-shaped steel of indent groove profile reinforcement and lightening hole, and this kind of C-shaped steel cross bar has simple in construction, in light weight, conveniently
The characteristics of construction, but the rigidity of this kind of C-shaped steel cross bar is relatively relatively low.Prior art also has the steel formed using a pair of shaped steel combinations
Matter support frame cross bar, to improve the rigidity of cross bar, but its structure design is not reasonable, and cost is high, and installation is not light enough.
The content of the invention
The purpose of this utility model is that rigidity is big, in light weight in view of the above-mentioned problems, providing a kind of reasonable in design,
Formwork-support cross bar easy to use.
Realizing the technical scheme of above-mentioned purpose is：A kind of formwork-support cross bar, has notch relative and is parallel to each other and set
A pair of the C-type steels put, the biside plate punishment positioned at a pair of C-type steels between a pair of C-type steels are furnished with the connecting plate being vertically arranged, institute
The lateral surface for stating connecting plate is located in the biside plate medial plane of the pair of C-type steel, each connecting plate and a pair of described C-type steels
It is formed by welding one；Upper and lower corresponding and shape and size identical hole is distributed with the trough floor of the pair of C-type steel.
Above-mentioned formwork-support cross bar, described hole are slot.
Above-mentioned formwork-support cross bar, described hole are slotted hole.
This formwork-support cross bar it is reasonable in design, have that rigidity is big, in light weight, cost is low, the light spy of installation
Point.

Fig. 1 is this formwork-support bar structure schematic diagram.
Fig. 2 is an example structure schematic diagram of this formwork-support cross bar.
Fig. 3 is another example structure schematic diagram of this formwork-support cross bar.
In figure：1st, C-type steel；2nd, connecting plate；3rd, hole.
Embodiment
Specific embodiment of the present utility model is illustrated with reference to accompanying drawing.
Such as Fig. 1, this formwork-support cross bar has notch relative and a pair of C-type steels 1 arranged in parallel, at this pair
Biside plate punishment between C-type steel 1 positioned at a pair of C-type steels 1 is furnished with the connecting plate 2 being vertically arranged, the lateral surface position of the connecting plate 2
In in the biside plate medial plane of the pair of C-type steel 1, each connecting plate 2 is formed by welding one with described a pair of C-type steels 1；
Upper and lower corresponding and shape and size identical hole 3 is distributed with the trough floor of the pair of C-type steel 1.
The C-type steel 1 of Fig. 1 embodiments is the C-type steel with inner bead, and hole 3 is slot, and connecting plate 2 is rectangular slab.
The C-type steel 1 of Fig. 2 embodiments is the C-type steel with inside edge, and hole 3 is slotted hole, and connecting plate 2 is square plate.
The C-type steel 1 of Fig. 3 embodiments is straight flange C-type steel, i.e. the section C-type steel similar to channel-section steel.
The hole 3 of this formwork-support cross bar is used for loss of weight, and connecting bolt hole when being docked as two cross bars.
Space between the C-type steel 1 of this formwork-support cross bar two forms through-wall bolt via.
