Preferably, the pre-buried position of Alkali-resisting fiberglass mesh layer is away from outer impeller outer surface 5-8mm.
Preferably, each wide Cast-in-Situ Segment 50mm out in construction band two sides.
The construction method of above-mentioned precast concrete shear wall Side fascia seam crossing connecting node:
1) one is inside contracted to internal lobe in plant produced precast concrete shear wall, the insulating layer of the concrete shear force wall and foreign minister
Fixed width degree pre-buried Alkali-resisting fiberglass mesh and stretches out the outer one fixed width of wall in outer impeller；
2) precast concrete shear wall is transported to construction site, hoisting prefabricated concrete shear force wall is installed, and two shear walls are pre-
Cast-in-Situ Segment is stayed, while formation width is greater than the construction band of Cast-in-Situ Segment between two shear wall siphonal lobes, pours showing between two precast wall bodies
Pour part；
3) prefabricated board of laminated floor slab is installed and pours overlapping layer concrete；
4) upper layer precast concrete shear wall is lifted；
5) it pastes and anchors the insulation board in reserved construction band；
6) in heat preservation plate surface applying mortar, the Alkali-resisting fiberglass mesh of indentation wherein side, when mortar slightly it is dry can extremely touch when, apply
Second mortar is smeared, then is pressed into other side Alkali-resisting fiberglass mesh, mortar is smeared to flat with impeller one outside two sides.
This construction method can accomplish wall face integral seamless gap, by the enhancing of Alkali-resisting fiberglass mesh, can be very good to prevent
Crack generates, simple and direct-viewing operation, guarantees construction quality, and exterior wall service life greatly increases, and is not present relative to sealant
Problem of aging.

Specific embodiment
Fig. 1, Fig. 2 shows existing precast concrete shear wall Side fascia seam construction, left side exterior wall siphonal lobes 11, right side
The construction joint 4 of about 5mm has only been reserved between exterior wall siphonal lobe 21, this construction joint can not be filled with mortar, it can only be filled up with sealant,
Due to sealant meeting aging feature, colloid is shunk after aging, construction joint is occurred and is filled not firm situation.
Illustrate in advance it is bright, the orientation or positional relationship of instructions such as " left side " as used in this specification " right side "
Words and phrases are intended merely to facilitate description this programme and simplify what description used, rather than indication or suggestion meaning shear wall is necessary for
Left and right opposite, shown in Fig. 2 is exactly the seam crossing practice of two shear walls of the upper side and lower side, therefore this orientation word is not
It can be interpreted as the restriction to scheme.3 to 6 pairs of technical solution of the present inventions are described in detail with reference to the accompanying drawing:
A kind of precast concrete shear wall Side fascia seam crossing connecting node, including left side exterior wall 1 and right side exterior wall 2, it is left
The construction band 5 greater than Cast-in-Situ Segment width, left side exterior wall siphonal lobe are equipped with outside side between 1 wall and the siphonal lobe (11 and 21) of right side exterior wall 2
11, which are equipped with side, is embedded in the Alkali-resisting fiberglass mesh layer 1 in concrete structure；Right side exterior wall siphonal lobe 21 is equipped with Alkali-resisting fiberglass mesh layer two
72；It is insulation board 6 on the inside of construction band 5, is mutually overlapping Alkali-resisting fiberglass mesh layer 1 and Alkali-resisting fiberglass mesh layer two on the outside of insulation board 6
72, Alkali-resisting fiberglass mesh layer 1 and Alkali-resisting fiberglass mesh layer 2 72 are screed cover 8 outside.
In conjunction with specific example, the construction method of above-mentioned precast concrete shear wall Side fascia seam crossing connecting node, specifically
Construction procedure are as follows:

Internal lobe 13 inside contracts one fixed width, pre-buried Alkali-resisting fiberglass mesh and stretches out the outer one fixed width of wall in outer impeller.Specifically, in which: insulating layer 12
It can be 50mm with respect to the width that internal lobe 13 inside contracts with siphonal lobe 11；The pre-buried position of Alkali-resisting fiberglass mesh is arranged away from outer impeller outer surface 5-
At 8mm, the width being embedded in siphonal lobe 11 is 50mm.The width design that pre-buried Alkali-resisting fiberglass mesh stretches out outer impeller is site operation
Width with 5 subtracts 20mm.
2) precast concrete shear wall is transported to construction site, hoisting prefabricated concrete shear force wall is installed, and two shear walls are pre-
Cast-in-Situ Segment 3 is stayed, the spacing of impeller is 3 width of Cast-in-Situ Segment in two shear walls, and the distance between siphonal lobe forms construction band 5, is based on
The structure of above-mentioned prefabricated concrete shear force wall, construction band are each wide Cast-in-Situ Segment 50mm out in two sides.Fixed two pieces of after-pouring is installed
Cast-in-place part between precast wall body；
3) prefabricated board of laminated floor slab is installed and pours overlapping layer concrete；
4) upper layer precast concrete shear wall is lifted；
5) it pastes and anchors the insulation board in reserved construction band；
6) in heat preservation plate surface applying mortar, the Alkali-resisting fiberglass mesh of indentation wherein side, when mortar slightly it is dry can extremely touch when, apply
Second mortar is smeared, then is pressed into other side Alkali-resisting fiberglass mesh, mortar is smeared to flat with impeller one outside two sides.
The present invention can be very good to prevent crack from generating, simple and direct-viewing operation by the enhancing of Alkali-resisting fiberglass mesh, can accomplish
Wall face integral seamless gap guarantees that construction quality, structure of the invention are not present problem of aging, can reach exterior wall service life significantly
Increase.
