Abstract
The invention relates to a reinforcement structure in a precast concrete external wall panel. According to the invention, a small-diameter small-spacing double-layer bidirectional steel wire mesh is welded and fixed by using obliquely inserted steel bars, such that a special truss is formed and is used as the reinforcement of the precast concrete external wall panel. The small-diameter small-spacing double-layer bidirectional steel wire mesh is formed by two layers of steel wire meshes with a specification of phi2-phi3mm@50mm. With the structure provided by the invention, integral rigidity is improved, wall panel deformation caused by extreme temperature change is avoided, tiny cracks on wall panel are prevented, and durability and safety are improved.
Description
Technical field
The present invention relates to construction engineering technical field, be specifically related to the reinforcement structure in a kind of precast concrete external wall panel.
Background technology
Reinforcement structure in the conventional art precast concrete external wall panel is single-layer bidirectional φ 6mm@150mm reinforced mesh arrangement of reinforcement, this large spacing, large diameter reinforced mesh arrangement of reinforcement integral rigidity are low, the wallboard strain cracking, affect construction quality and safe application performance when the temperature acute variation.
Summary of the invention
Technical problem to be solved by this invention is: solve the problem that above-mentioned prior art exists, and provide a kind of and improve integral rigidity, the reinforcement structure when avoiding extreme temperature in the precast concrete external wall panel of cracking, excellent in durability.
The technical solution used in the present invention is: the reinforcement structure in this precast concrete external wall panel is: adopt the closely spaced double-layer double-direction steel fabric sheet of minor diameter to be fixed into space net rack by the welding of oblique cutting reinforcing bar, as the arrangement of reinforcement of precast concrete panel.
In technique scheme, the closely spaced double-layer double-direction steel fabric sheet of described minor diameter is two layers of the reinforced mesh of φ 2 ~ φ 3mm@50mm.
Operating principle and advantageous effect:
Two layers of the reinforced mesh of wallboard employing φ 2 ~ φ 3mm@50mm are welded into space net rack, fluid concrete in mould with 3 D stereo oblique cutting reinforcing bar (abdomen muscle).The integral rigidity of wallboard is higher more than 14% than traditional single-layer bidirectional φ 6mm@150mm reinforced mesh arrangement of reinforcement.The steel wire of little spacing, minor diameter has very great help to the crack resistance that improves wallboard simultaneously, can resist the wallboard deformation that extreme changes of temperature causes.Guarantee that wallboard does not produce minute crack, improve durability and safety.
Description of drawings:
Fig. 1 is structural representation of the present invention.
In figure, 1-top mat sheet, 2-lower floor reinforced mesh, 3-oblique cutting reinforcing bar.
The specific embodiment:
Referring to Fig. 1, reinforcement structure in precast concrete external wall panel of the present invention is: adopt the welding of the closely spaced double-layer double-direction steel fabric sheet of minor diameter oblique cutting reinforcing bar to be fixed into space net rack, as the arrangement of reinforcement of precast concrete panel, the closely spaced double-layer double-direction steel fabric sheet of described minor diameter is two layers of the reinforced mesh of φ 2 ~ φ 3mm@50mm.
