Problems solved by technology

Especially for concrete beams, workers usually do not bend the steel bars according to the most reasonable way of reinforcement (such as figure 1 shown), they are more willing to match the straight reinforcement on both sides of the beam (such as figure 2 shown), and then form it into a whole by binding the erection steel bars and stirrups. The whole process is undoubtedly time-consuming and laborious, and there will always be one side of the straight steel bars that does not really bear the force, which is uneconomical

Embodiment Construction

[0020] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0021] Such as Figure 3-4 As shown, a truss-type reinforced concrete beam includes a concrete beam body and a space truss arranged inside the concrete beam body. The space truss includes four-product steel trusses 1: the left and right two-product steel trusses bear most of the bottom tensile force and part of the bending moment of the beam; the upper and lower two products mainly play the role of erection. Through welding or lashing, the four-product steel truss is assembled into a space truss to form a rigid whole. The said steel truss is provided with diagonal rods 2.

[0022] The construction steps of the above reinforced concrete beam have the following characteristics:

[0023] Prefabricated single-product steel trusses (such as Figure 4 ), the width of each steel truss can be produced according to the modulus specified in the "Reinforced Concrete Beam ...

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 [0001] The invention relates to a building structure, in particular to a truss type reinforced concrete beam. Background technique [0002] Nowadays, the application of reinforced concrete is more and more extensive. At present, in China, reinforced concrete is the most used structural form, accounting for the vast majority of the total, but there is no doubt that reinforced concrete also has many defects in construction. Especially for concrete beams, when distributing steel bars, workers usually do not bend the steel bars according to the most reasonable reinforcement method (such as figure 1 Shown), they are more willing to equip the beams with straight steel bars (such as figure 2 As shown), the erecting steel bars and stirrups are bound to form a whole. The whole process is undoubtedly time-consuming and laborious, and there is always one side of straight steel bars that does not really bear the force, which is not economical. Summary of the invention [000...
