It is wrapped up using 60mm thickness armored concrete, wallboard entirety fire protecting performance can reach A grades.
Summary of the invention
For the above technical problems, the purpose of the present invention is to provide a kind of built-in white steel fasteners of bent
Precast concrete super low energy consumption Sandwich insulation wallboard, the white steel fastener of bent have thermal coefficient small, tension and shearing strength
Height, corrosion resistant advantage.The anchoring strength of the white steel fastener of bent can largely influence the use of connector, this bent
White steel fastener, two sides add short muscle respectively to reinforce anchoring at inflection point, guarantee stability of the connector in concrete and
Reliability increases substantially the integral working that such insulation layer thickness is more than the super low energy consumption heat insulating sandwich wallboard of 100mm,
Its connector transmission force property is reasonable, facilitates lifting, is particularly suitable for domestic current design specification and assembled current situation.
In order to achieve the above object, the technical scheme is that
A kind of white steel fastener precast concrete super low energy consumption Sandwich insulation wallboard of built-in bent, has three-layer structure,
It is followed successively by internal lobe wall, middle part insulating layer, siphonal lobe wall from inside to outside, the white steel fastener of bent is built in internal lobe wall, middle part heat preservation
The inside of layer, siphonal lobe wall, is connected to become entirety for internal lobe wall, insulating layer, siphonal lobe wall by the white steel fastener of bent.
The white steel fastener precast concrete super low energy consumption Sandwich insulation wallboard of the built-in bent, internal lobe wall is using general
Logical concreting forms, and the double-deck internal lobe wall steel mesh of shear wall force request configuration, the double-deck internal lobe wall steel are pressed to internal lobe by portion within the walls
It is connected between muscle net by tension rib；Siphonal lobe wall is poured using normal concrete or lightweight concrete, and inside configuration is single
Layer siphonal lobe wall steel mesh, middle part insulating layer use non-ignitable or fire retardant insulation board.
The white steel fastener precast concrete super low energy consumption Sandwich insulation wallboard of the built-in bent, built-in bent
White steel fastener is bent by Bai Gang, in which: the vertex dog-ear of the white steel fastener of bent is 80~100 °, apex
Weld manomelia anchor bar in parallel up and down, using inflection point as midpoint, manomelia anchor bar stretches out 100~200mm, manomelia anchor to every side
Gu the length of reinforcing bar totally 200~400mm；The bottom both ends of the white steel fastener of bent distinguish 130~140 ° of outward bending, are formed
The bending segment of 40~60mm of each elongation, each bending segment weld manomelia anchor bar, centered on inflection point, manomelia in parallel up and down
Anchor bar stretches out 100~200mm, the length of manomelia anchor bar 8 totally 200~400mm to every side.

Gas corrosion and elevated temperature strength are high, can use under conditions of severe cruel, processing hardening is excellent (nonmagnetic), can be used for setting
The production equipments such as standby, chemical, dyestuff, papermaking, oxalic acid, fertilizer, it can also be used to take pictures, food industry, coastal area facility, rope
Rope, CD bar, bolt, nut.316 stainless steel chemical components are as follows: C≤0.08, Si≤1.00, Mn≤2.00, P≤0.035, S
More than≤0.03, Ni:10.0~14.0, Cr:16.0~18.5, Mo:2.0~3.0, Fe；316 stainless steel machinery properties are as follows: anti-
Tensile strength (MPa) is 620MIN, and yield strength (MPa) is 310MIN, and elongation (%) is 30MIN, and area reduction (%) is
40MIN, the density 8.03g/cm of 316 stainless steels3。
The invention has the advantages and beneficial effects that:
(1) present invention is using the white steel fastener of bent as prefabricated concrete super low energy consumption Sandwich insulation wallboard
Connector, this kind of material have tension, resistance to compression, shearing strength high, and ductility is good, and safety stock is high, and corrosion resistance is strong, thermally conductive system
The small advantage of number, and concrete, Bai Gang, reinforcing bar three's linear expansion coefficient are close, and the temperature deformation coordination ability is good, can effectively mention
The thermal insulation property and endurance quality of high prefabricated concrete super low energy consumption Sandwich insulation wallboard, solve universality material selection
Problem.
(2) stud connector design of the invention is bent, and Path of Force Transfer is clear, stability is good, can with concrete anchoring
It leans on, shearing strength, durability, the entirety that insulation layer thickness is more than the super low energy consumption heat insulating sandwich wallboard of 100mm can be greatly improved
