There is strip groove 47 corresponding with strip groove 36.Poured at internal lobe wall 11 cement mortar fix upper Prefabricated sandwich type wall panel 1 with
Lower Prefabricated sandwich type wall panel 2, cement mortar flow into strip groove 36 and strip groove 47, increase the contact area of mortar and wallboard, sand
Slurry attachment is stronger, the horizontal-shift between wallboard can be reduced in vertical direction assembly wallboard, upper and lower two after mortar solidification
The connection of block wallboard is closer, further prevents moisture penetration to interior.
Working principle is as follows:
When Prefabricated sandwich type wall panel 1 in assembly and lower Prefabricated sandwich type wall panel 2, water swelling item 1 and water swelling item two
41 mutual extrusions, the horizontal joint 21 between clogging upper Prefabricated sandwich type wall panel 1 and lower Prefabricated sandwich type wall panel 2, prevent moisture from
Siphonal lobe wall 13 is permeated to insulation board 12.In moisture penetration to horizontal joint 21, water swelling item 1, water swelling item 2 41
Energy water swelling stops gap.Water swelling item 1 is synthesized by the inorganic water uptake expansion material of macromolecule and rubber, is met
The expansion of water energy water suction volume, to stop gap, forms fluid-tight plasticity colloid, the waterproofness at seam of improving the standard 21
Energy.
Cement mortar is poured at internal lobe wall 11 fixes upper Prefabricated sandwich type wall panel 1 and lower Prefabricated sandwich type wall panel 2, cement bonded sand
Slurry flows into strip groove 36 and strip groove 47, increases the contact area of mortar and wallboard, and mortar attachment is stronger, in vertical side
The horizontal-shift between wallboard can be reduced when to assembled wallboard, two pieces of wallboards connections are closer up and down after mortar solidification, further
Prevent moisture penetration to interior.
Embodiment two:
A kind of prefabricated sandwich heat preservation exterior wall horizontal joint, referring to Fig. 4 and Fig. 5, based on embodiment one, the present embodiment
Difference with embodiment one is: the section of strip groove 36 is trapezoidal.
Working principle is as follows:
On the one hand the trapezoidal strip groove 36 in section and strip groove 47 increase the contact area between mortar and wallboard,
So that mortar attachment is stronger；On the other hand, the mortar filled in the mortar and strip groove 47 filled in strip groove 36 is solidifying
Gu the structure that similar dove-tail form is formed after, upper Prefabricated sandwich type wall panel 1 is connect with lower Prefabricated sandwich type wall panel 2 closer, is not easy
It loosens, further prevents moisture penetration to interior.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
