Abstract
The invention relates to a trussed type reinforced concrete beam, comprising a concrete beam body and a space truss arranged inside the concrete beam body, wherein the space truss is formed by combining four reinforced trusses, namely an upper reinforced truss, a lower reinforced truss, a left reinforced truss and a right reinforced truss, and the reinforced trusses are prefabricated. Compared with the prior art, the trussed type reinforced concrete beam disclosed by the invention has the advantages of convenience in construction, conservation of construction time and high overall strength.
Description
Technical field
The present invention relates to a kind of building structure, especially relate to a kind of truss-like reinforced concrete beam.
Background technology
Nowadays, the application of steel concrete more and more widely at present.In China, steel concrete accounts for the overwhelming majority of sum for using maximum a kind of form of structure at present, but undoubtedly, also there are a lot of defectives in steel concrete aspect construction.Especially for concrete beam, when joining reinforcing bar, the workman is because fear trouble; Usually can not come moment reinforcement (as shown in Figure 1) according to the most rational reinforcement manner; They more are willing to be intended to going up of crossbeam and mix perfectly straight reinforcing bar (as shown in Figure 2) to both sides, through the colligation to handling reinforcement and stirrup it are formed integral body then, and whole process undoubtedly wastes time and energy; And perfectly straight reinforcing bar always has a side and does not really bear stressed, uneconomical.
Summary of the invention
The object of the invention be exactly in order to overcome the defective that above-mentioned prior art exists a kind of easy construction is provided, can saves the engineering time, truss-like reinforced concrete beam that intensity is high.
The object of the invention can be realized through following technical scheme:
A kind of truss-like reinforced concrete beam comprises concrete beam body and is arranged at concrete beam body volume inside truss, and described space truss is combined by four steel bar girders up and down.
Described steel bar girder is prefabricated, and during construction, described four steel bar girders up and down are through welding or colligation combination.
Described steel bar girder is provided with brace.
Compared with prior art, the present invention has the following advantages:
1) with existing construction technology contrast, this job practices is convenient, can realize prefabrication, has greatly saved the time that workman's assembling reinforcement is spent.
2) replace the effect of stirrup with the brace in the truss, thereby strengthened the globality of reinforcing cage.
3) this beam each side stress performance big lifting of Liang Yougeng of joining with respect to common reinforcing bar.(can know that through the mathmatic analysis this beam can promote 10% intensity)
4), thereby improved the snap-in force between concrete and the reinforcing bar through the effect between brace and the concrete.
5) brace can substitute the part of bent-up bar in the phase concrete beam, thereby the crack of having controlled this beam occurs.
6) given full play to the measuring body performance of reinforcing bar tension concrete.
7) very strong engineering practice property is arranged.

Fig. 2 is the existing reinforced concrete beam sketch map of being furnished with perfectly straight reinforcing bar;
Fig. 3 is the structural representation of concrete beam of the present invention;
Fig. 4 is the structural representation of steel bar girder of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
Shown in Fig. 3-4, a kind of truss-like reinforced concrete beam comprises concrete beam body and is arranged at concrete beam body volume inside truss.Space truss comprises four article steel bar girders 1: two article steel bar girders have been born the most of bottom pulling force of beam and the moment of flexure of part wherein; And two article mainly play the upright effect of frame up and down.Through welding or colligation, it is space truss that four article steel bar girders are pieced together, and makes it form the integral body that rigidity is arranged.Described steel bar girder is provided with brace 2.
The construction sequence of above-mentioned reinforced concrete beam has following characteristics:
Earlier prefabricated single article steel bar girders (like Fig. 4), the width of every article steel bar girder can be produced according to the modulus of regulation in " reinforced concrete beam job specfication ", thereby makes large-scale production become possibility.Realize that prefabrication can greatly shorten man-hour, and marginal cost is reduced.
Only need the workman with prefabricated welding of four article steel trusss or colligation in the work progress, make it can have certain rigidity and get final product.
At the outside concreting of the space truss that combines, form reinforced concrete beam.Wherein up and down two reinforcing bars are joined by calculating.And about the effect of serving as stirrup of brace in the two article truss, need to calculate and try to achieve.Consider that beam is main to receive curved and axle power generally, so less demanding to the side direction stirrup, subtracting that the brace of two article can be suitable up and down is thin, thereby the saving steel using amount reduces cost.
Claims (3)
1. a truss-like reinforced concrete beam is characterized in that, comprises concrete beam body and is arranged at concrete beam body volume inside truss, and described space truss is combined by four article steel bar girders up and down.
