Description
Technical field
The present invention relates to precast concrete sandwich heat preserving wall plate technique field, a kind of half built-in is related in particular to prefabricated
The wallboard assembly system of concrete sandwich this body structure of heat-insulation wall plate and its composition, with construction method.
Background technology
At present, it is adaptable to which the most ripe assembling retaining wall of the technology of steel building is curtain wall system and steam pressurized
Concrete prefabricated batten wall.Wherein, precast concrete sandwich heat preservation wallboard is widely used in concrete structure building, is tool
The retaining wall assembling technology of the potentiality that grow a lot, it is contemplated that many poor performances of steel construction and concrete structure
Different, on the premise of " compatibility " problem between considering different material, the relevant connection for concrete structure is constructed in practice
It is to be difficult to directly apply to steel building.
Steel construction retaining wall technology should take into full account the self-characteristic of steel construction：
(1) steel construction is independent stress system and lighter weight, should use the Light Wall of non-bearing；
(2) poor rigidity of steel construction, stratified deformation is larger, and wall should use flexible connection mode, to adapt to agent structure
Deformation；
(3) " cold-heat bridge " and " overhead speaker " outstanding problem of steel construction, wall should have good insulation and sound insulation property
Energy；
(4) steel structure fire-resistant and decay resistance are poor, and wall should be able to be protected very well；
(5) the prefabrication and assembly construction degree of steel construction is higher, and wall correlation technique should be as far as possible matching.
As Fig. 1 to Fig. 3 shows existing wallboard cross section and organigram, now with precast concrete sandwich heat preserving wall
Plate 10 (hereinafter referred to as heat-insulation wall plate 10) its structure includes outer impeller 11, siphonal lobe bar-mat reinforcement 12, adiabator layer 13, interior impeller

It is coated with the structure of the outer impeller 11 (Fig. 1) of siphonal lobe bar-mat reinforcement 12.Then, placed by by insulation material (rock wool, mineral wool etc.)
In outer impeller 11 towards on the one side of steel bar truss web bar 16, or, poured by using foam concrete as insulation material
In outer impeller 11 towards on the one side of steel bar truss web bar 16, and then form the internal insulation material for being coated with steel bar girder 16
13 (Fig. 2) of layer.Finally, after placing the positioning of internal lobe bar-mat reinforcement 15, by the longitudinal reinforcement of internal lobe bar-mat reinforcement 15 and reinforcing bar purlin
The abdomen muscle welding of frame abdomen muscle 16, then casting concrete is outside internal lobe bar-mat reinforcement 15, and internal lobe bar-mat reinforcement is coated with to form inside
15 structure of interior impeller 14 (Fig. 3).
It is worth noting that, as shown in figure 3, the steel bar truss web bar 16 of existing heat-insulation wall plate 10 is with perpendicular to outer impeller
The prominent form on 11 surfaces and the surface of interior impeller 14 inside heat-insulation wall plate 10, that is, between outer impeller 11 and interior impeller 14,
It is weak so as to there is structure when two impeller are in stress in the absence of other attachment structures between adjacent steel bar truss web bar 16
Point.Furthermore, the concrete impeller of present heat-insulation wall plate 10 typically uses fibre reinforced composites (Fiber Reinforced
Polymer/Plastic, abbreviation FRP) or stainless steel adapting piece, it is desirable to have special technology realizes connection, for construction technology
Requirement it is relatively high, and construction after it is also not satisfactory for the globality of heat-insulation wall plate 10.
