Feature and effect：
The present invention is a kind of overlapping exterior wall L-type connecting node, overlaps exterior wall and independent corner heat preserving prefabricated part by factory
Prefabricated, standardized work is produced, quality controllable, efficient, speed is fast, energy saving, and environmental protection avoids ring caused by site operation
It pollutes in border.Overlapping exterior wall particularly of the invention and independent corner heat preserving prefabricated part are the prefabricated component with heat insulation function, thus
It is most important for the heat preservation energy-saving of building.On the one hand the present invention uses in the L-type right angle connecting node of two overlapping exterior walls
The length of the external thermal insulation prefabricated board and insulating layer that overlap exterior wall is more than the length of siphonal lobe wallboard and internal lobe wallboard, on the other hand, work
When factory produces prefabricated dedicated independent corner heat preserving prefabricated part and be connected with two overlapping exterior wall l-shaped right angles, first overlaps exterior wall, only
Vertical corner heat preserving prefabricated part, the second overlapping exterior wall are sequentially connected, in this way, just making the L-type connecting node of overlapping exterior wall still have
Whole external thermal insulation prefabricated board and insulating layer, the L-type connecting node insulation construction for overlapping exterior wall are not destroyed, and maintain assembled
The energy saving technique effect of integral heat insulation is built, compared with the prefabricated overlapping Side fascia of the prior art and prefabricated overlapping Side fascia l-shaped
It is covered when right angle assembles using cast-in-place column or the cast-in-place no insulating layer of stretching bar splicing, the present invention is a technical much progress.
In addition, it is stretched out on the inside of the overlapping exterior wall L-type connecting node of the present invention using two overlapping exterior wall siphonal lobe wallboards and internal lobe wall panel ends
Reserve U-shaped connection bar splicing, and in lap-joint's suit square shape stirrup, insertion vertical structure reinforcing bar, then cast-in-place coagulation
Earth forming is fixed, and structural strength is high, and overall performance is good.Again since overlapping exterior wall is sequentially connected external thermal insulation prefabricated board, keeps the temperature
The laminar product that layer, siphonal lobe wallboard, intermediate in-situ layer and internal lobe wallboard are formed, thus exterior wall is overlapped with regard to inevitably having layer
Shape interiors of products connection structure intensity is low and the shortcomings that globality poor, for this purpose, the present invention be additionally arranged in intermediate in-situ layer it is vertical
Reinforcing bar is connected, greatly strengthens the structural strength of intermediate in-situ layer.The present invention is also selectively cast-in-place in siphonal lobe wallboard, centre
Layer increases with the square stirrup and/or truss bars that bridging is embedded in internal lobe wallboard and selectively in intermediate in-situ layer
If vertically connection reinforcing bar and on it binding tie hoop or rectangle cuff.The construction of adding of these above-mentioned selectivity greatly increases
The structural strength and overall performance that strong siphonal lobe wallboard, intermediate in-situ layer are connected with internal lobe wallboard, overcome prior art stratiform
The defects of product.
