Abstract

The utility model discloses a reinforcing rib structure in a prefabricated concrete external wall panel. Small-diameter small-distance double-layer double-directional steel wire meshes are adopted to be welded and fixed into a space mesh frame by inclined insertion steel bars and serve as reinforcing ribs of the prefabricated concrete wall panel; and the diameter of each small-diameter small-distance double-layer double-directional steel wire mesh is 2 to 5 millimeters; and the distance between two layers of steel bar meshes is 50 millimeters. By the reinforcing rib structure, the integral rigidity is improved, wall panel deformation due to extreme temperature change is avoided, tiny cracks cannot be formed on the wall panel, and the durability and the safety of the wall panel are improved.

Description

Reinforcement structure in a kind of precast concrete external wall panel
Technical field:
The utility model relates to construction engineering technical field, is 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 a single-layer bidirectional φ 6mm150mm reinforced mesh arrangement of reinforcement; This big spacing, large diameter reinforced mesh arrangement of reinforcement integral rigidity are low; The wallboard strain cracking influences construction quality and safe application performance when the temperature acute variation.
The utility model content:
The utility model technical problem to be solved 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 scheme that the utility model adopts 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 through the welding of oblique cutting reinforcing bar, as the arrangement of reinforcement of precast concrete panel.
In the 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 2mm～φ 3mm50mm.
Operating principle and advantageous effect:
Two layers of the reinforced mesh of wallboard employing φ 2mm～φ 3mm50mm 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 6mm150mm 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 or other external force cause.Guarantee that wallboard does not produce minute crack, improve durability and safety.
Description of drawings:
Fig. 1 is the utility model structural representation.
Among the 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 the precast concrete external wall panel of the utility model is: adopt the closely spaced double-layer double-direction steel fabric sheet of minor diameter to be fixed into space net rack through the welding of oblique cutting reinforcing bar; 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 2mm～φ 3mm50mm.

Claims (2)
