Abstract
The utility model provides a bidirectional prestress steel wire net rack wall plate which comprises a plate core and surface layers, wherein a surface layer is arranged on each of two sides of the plate core; a steel wire net sheet is arranged inside each of the surface layers; longitudinal inclined drew web wires and transverse inclined drew web wires which penetrate through the surface layers and the plate core are welded between the steel wire net sheets; and transverse prestress steel bars and longitudinal prestress steel bars are arranged inside the surface layers. The bidirectional prestress steel wire net rack wall plate has the advantages that the cracking resistance, the rigidity and the permeation resistance of a structural member are improved, the performances of the materials are given a full play, steel materials are saved, and the heat preservation performance is improved.
Description
Technical field
The utility model belongs to field of house buildings, especially relates to a kind of two dimension prestressing metal lath trabs.
Background technology
In the building construction, once adopted a kind of prefabricated panel member that consists of with cage of reinforcement and layer of concrete, the coated whole skeleton of layer of concrete, the two sides, front and back of the cage of reinforcement that namely is laid in and four peripheries.In the structure of ordinary reinforced concrete, because the concrete ultimate tensile strength is low, under the service load effect, the strain of reinforcing bar has substantially exceeded concrete ultimate tensile strength in the member.Reinforced steel bar strength in the reinforced concrete member is not fully utilized.So ordinary reinforced concrete structure, it is irrational adopting high strength cast iron.
In recent years, countries in the world are paid attention to the research and development of energy-saving building material more.In numerous energy saving building goods, the composite board system is with its excellent performance, and cheap price is developed rapidly, but it still needs further raising on intensity and heat insulation effect.
Summary of the invention
Problem to be solved in the utility model provides a kind of two dimension prestressing metal lath trabs, has especially improved crack resistance, rigidity and the impermeability of member, has given full play to the performance of material, saving steel, and heat insulation effect increases.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of two dimension prestressing metal lath trabs, comprise plate core and surface layer, the both sides of described plate core are respectively equipped with surface layer, the inside of described two surface layers is respectively equipped with a steel fabric sheet, between described steel fabric sheet, be welded with the vertical oblique pull abdomen silk and the horizontal oblique pull abdomen silk that run through surface layer and plate core, in described surface layer, also be provided with transverse prestressed reinforcing steel bar and longitudinal prestressing reinforcing bar.
Further, described plate core is perlite.
Further, described vertical oblique pull abdomen silk and laterally oblique pull abdomen silk intersect respectively the shape that assumes diamond in shape and arrange.
Further, described transverse prestressed reinforcing steel bar and longitudinal prestressing reinforcing bar are respectively along the horizontal and vertical arrangement of steel fabric sheet.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, so that the utlity model has crack resistance, rigidity and the impermeability that has improved member, give full play to the performance of material, saved steel, improved the advantages such as heat-insulating property.

The specific embodiment
Such as Fig. 1,2, shown in 3, the utility model comprises plate core 1 and surface layer 2, the both sides of described plate core 1 are respectively equipped with surface layer 2, described surface layer 2 is layer of concrete, the inside of described two surface layers 2 is respectively equipped with a steel fabric sheet 3, between described steel fabric sheet 3, be welded with the vertical oblique pull abdomen silk 4 and the horizontal oblique pull abdomen silk 5 that run through surface layer 2 and plate core 1, vertically oblique pull abdomen silk 4 and laterally oblique pull abdomen silk 5 intersects respectively the shape arrangement that assumes diamond in shape, namely so that each solder joint connects the abdomen silk of two different directions, structure is more firm, intensity is higher, in described surface layer 2, also be provided with transverse prestressed reinforcing steel bar 6 and longitudinal prestressing reinforcing bar 7, in order to take full advantage of high-strength material, remedy the gap between the concrete and rebar stretching strain, prestressing force is applied in the reinforced concrete structure go, before namely outer load is applied on the member, (mainly being the tensile region) applies pressure on member in advance, consists of prestressed reinforced concrete structure.When member bears the pulling force that is produced by external load, at first offset existing prestressing force in the concrete, then increase with load, could be so that the crack then appear in concrete in tension, thereby postponed the appearance of structure member crevices and carry out.Plate core 1 adopts perlite, and this material has better heat insulation effect and waterproof effect compared with polystyrene foam plastics or rock wool in the past.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
