The anti-flexion capabilities of web of shaped steel are relatively low, by height and thickness ratio limited, when need compared with large bearing capacity when or it is more demanding
During stability, the thickness of web need to be thickeied, and need to increase other structures, thus increase the load of component, give processing band
It is inconvenient to come, and brings more inconvenience to construction；It due to the design feature of T-steel, is particularly in structural steelwork in engineering, choosing
It is restricted with the flexibility ratio of section bar.
Invention content
It is an object of the present invention to provide a kind of folded plate type truss-type steels, it substitutes existing T-steel, can solve existing skill
The deficiency of art.
The present invention to achieve the above object, is achieved through the following technical solutions：A kind of folded plate type truss-type steel, including even
Bar, connecting rod are connect respectively with several first inclined plates and several second inclined plates, and several first inclined plates are mutually parallel distribution, and several second
Inclined plate is mutually parallel distribution, and first inclined plate one end and the overlapping connection of second inclined plate one end are set between the first inclined plate and the second inclined plate
First angle α1, the first angle α1It is 30 ° -70 °.Second angle α is set between the second inclined plate and connecting rod2, the second angle α2For
110°-150°.First inclined plate one end and the second inclined plate intersecting lens set third angle α with link width direction3.Third angle α3
It is 25 ° -55 °.First inclined plate one end and second inclined plate one end overlap mutually merging and are connected with connecting rod, the first inclined plate and the second inclined plate phase
The overlapping width L closed2It is the width of the first inclined plate or the second inclined plate.The cross section of connecting rod is c-type.The cross section of connecting rod is groove
Type.The cross section of connecting rod is square type.Setting cavity among connecting rod, the interior filling mortar of cavity or concrete.
Present invention is especially suited in structural steelwork, component combine building and assembled architecture in use, bearing capacity
Height, the thinner thickness of web direct shearing can use, be applicable in various engineering structures, can carry larger as needed
Load, overall stability and local stability are preferable, in the case of same bearer power, save steel 20-25%, for construction
Provide larger convenience etc..The present invention substitutes the T-steel of the prior art, and is applied in each field.

Specific embodiment
Compareing attached drawing, the present invention will be further described.
A kind of folded plate type truss-type steel of the present invention, including connecting rod 1, connecting rod 1 respectively with several first inclined plates 3 and several the
Two inclined plates 4 connect, and several first inclined plates 3 are mutually parallel distribution, and several second inclined plates 4 are mutually parallel distribution, the first inclined plate 3 and
Two inclined plates, 4 one end connects, the first angle α of setting between the first inclined plate 3 and the second inclined plate 41, the first angle α1It is 30 ° -70 °.This
The alternative existing T-steel of the result is invented to use in various engineerings, especially suitable in the building of combination of architectural fabric,
Its inclined plate is process using one piece of steel plate bending, and steel plate bending is divided into oblique bending or positive bending, the angle of oblique bending
Generally 10 ° -70 ° of degree, the various angles of oblique bending are different according to the stress difference and function used and adjust, and increase office
Portion's stability and the using flexible in engineering.It is thin that the above structure of the present invention can do the thickness of inclined plate, makes integrated carrying
Power enhances, and local stability and overall stability improve 30%-40% than existing T-steel, whole in the case of equal bearing capacity
Weight ratio T-steel reduces 15% or so, has great advantage easy to use in the architectural engineering of fabricated construction.
Preferred embodiments of the present invention are：Second angle α is set between second inclined plate 4 and connecting rod 12, the second angle α2For 110 °-
150 °, this angle of inclination can make the bearing capacity of shaped steel of the present invention reach preferable states, and be easy to cut out use as needed.
Further embodiment of the present invention is：First inclined plate, 3 one end and 4 intersecting lens of the second inclined plate are set with 1 width direction of connecting rod
Put third angle α3.Third angle α3Preferred angle is 25 ° -55 °, after tested, this angle make shaped steel overall stability compared with
In the case of good, also there is fabulous stability in part.
Further embodiment of the present invention is：Merging and 1 phase of connecting rod are overlapped mutually in first inclined plate, 3 one end and 4 one end of the second inclined plate
Even, the first inclined plate 3 and the width L of the intersecting overlapping of the second inclined plate 42It is the width of the first inclined plate 3 or the second inclined plate 4, this structure
Convenient for using a steel plate bending, into the first inclined plate 3 and the second inclined plate 4, manufacture is at low cost, and whole load-bearing capacity is high, holds part
Weight uniformity is more preferable.
