Description

Intersecting parallels insulation and precast concrete external wall panel

Technical field

The utility model is related to assembled architecture wall technology fields, more particularly, to one kind in precast concrete external wall panel The middle intersecting parallels insulation used.

Background technology

Assembled architecture is built using precast concrete wall panel, batch production, the mechanization degree of construction can be improved, Situ wet operation is reduced, live recruitment is saved, overcomes seasonal effect, shorten the construction period.

Currently, the precast concrete external wall panel with sandwich heat preservation layer is made of inside and outside wall board and sandwich heat preservation layer, sandwich guarantor Warm layer is usually the lower flame-retardant heat insulating material of thermal conductivity coefficient, such as extruded sheet, polyurethane foamed board or foam glass, but it is thick Degree must not exceed 120mm, the too thick intensity for influencing whether external and internal wall, and inside and outside metope generally uses the oblique stitch of reinforcing bar, but inside and outside Wall will produce larger thermal conductivity by reinforcing bar, and inner wall surface winter has dew condensation phenomenon generation.To overcome this disadvantage, can be used High-strength thermal insulation fiberglass rod connects external and internal wall, but to be still difficult with high temperature resistant ultralow for the sandwich heat preservation layer in the case The vacuum heat-insulating plate of thermal coefficient is built because if using vacuum heat-insulating plate since the vacuum of vacuum heat-insulating plate is corrupted such that Building integral heat insulation, the effect is unsatisfactory.

In addition, being difficult to after mounting prefabricated using vacuum heat-insulating plate as the precast concrete external wall panel of sandwich heat preservation layer The wall face of concrete external wall panel punches, and to be difficult to be fixed to expansion bolt in precast concrete exterior wall from the outside, makes Be difficult on the precast concrete exterior wall using vacuum heat-insulating plate as sandwich heat preservation layer it is outer by expansion bolt is installed Hang stone curtain wall or plug-in steel mesh patch block.

Therefore current urgently exploitation one kind is thinner with thickness of wall body, heat-insulating property is more preferable and can continue on wall face Construction punching is with the precast concrete external wall panel of plug-in steel mesh and stone curtain walls.
