Feature and effect:
The present invention is a kind of overlapping exterior wall L-type connecting node, and overlapping exterior wall is prefabricated by plant produced, standardized work,
Quality controllable, efficient, speed is fast, energy saving, and environmental protection avoids environmental pollution caused by site operation.It is particularly of the invention
Overlapping exterior wall be the prefabricated overlapping exterior wall with heat insulation function, it is thus most important for the heat preservation energy-saving of building.This hair
It is bright to be more than in the L-type right angle connecting node of two overlapping exterior walls using the external thermal insulation prefabricated board of overlapping exterior wall and the length of insulating layer
The length of siphonal lobe wallboard and internal lobe wallboard, when two overlapping exterior wall l-shaped right angles connect, the external thermal insulation prefabricated board of the first overlapping exterior wall
And insulating layer side end face linear extension is to the second overlapping external thermal insulation prefabricated board of exterior wall and insulating layer side.In this way, just make overlapping
The L-type connecting node of exterior wall still has complete external thermal insulation prefabricated board and heat insulation layer structure, and the L-type connecting node for overlapping exterior wall is protected
Warm structure is still retained, and maintains the energy saving technique effect of assembled architecture integral heat insulation, prefabricated folded compared with the prior art

Covering, the present invention is a technical much progress.In addition, using two overlappings on the inside of the overlapping exterior wall L-type connecting node of the present invention
U-shaped connection bar splicing that exterior wall siphonal lobe wallboard and internal lobe wall panel ends stretched out reserve, and lap-joint's suit square shape stirrup,
Vertical structure reinforcing bar is inserted into, last cast-in-place concrete shaping is fixed, and structural strength is high, and overall performance is good.Again due to overlapping exterior wall
For the laminar product that sequentially connected external thermal insulation prefabricated board, insulating layer, siphonal lobe wallboard, intermediate in-situ layer and internal lobe wallboard are formed,
Thus overlapping exterior wall just inevitably has the shortcomings that laminar product inner connecting structure intensity is low and globality poor, for this purpose,
The present invention is additionally arranged vertical connection reinforcing bar in intermediate in-situ layer, greatly strengthens the structural strength of intermediate in-situ layer.This hair
The bright square stirrup and/or Truss Steel that bridging is also selectively embedded in siphonal lobe wallboard, intermediate in-situ layer and internal lobe wallboard
Tie hoop or rectangle cuff are bound on muscle and the vertical connection reinforcing bar selectively added in intermediate in-situ layer.It is above-mentioned
The structural strength and entirety that these selective structures significantly enhance siphonal lobe wallboard, intermediate in-situ layer is connected with internal lobe wallboard
Performance, the defects of overcoming prior art laminar product.
