Description
Technical Field
The utility model relates to an assembly building construction technical field, in particular to precast concrete externally-hung wallboard perps drainage device that blocks water.
Background
At present, the assembly type building is one of the development directions of the modern buildings in China, the building industrialization gradually develops towards the directions of green, energy saving and environmental protection due to the appearance of the assembly type building, and the precast concrete external wall panel is one of the important components of the assembly type building system.
For the fabricated building, the waterproof treatment of the splicing seam of the precast concrete external wallboard is a difficult problem. The water-proof treatment measures include draining water reserved in the cavity, and the water can cause leakage, the quality of materials at the splicing seam is reduced and even fails, so that the applicability of the building is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at accelerating the discharge of water in the precast concrete externally-hung wallboard cavity, providing a precast concrete externally-hung wallboard perps drainage device that blocks water.
The utility model relates to a precast concrete externally-hung wallboard perps drainage device that blocks water, including "n" type back lining, sealed glue. The waterproof and drainage device is of an n-shaped structure, the n-shaped backing is arranged at a vertical seam below a cross seam of the precast concrete externally-hung wallboard, the sealant is arranged at the top of the n-shaped backing, the top sealant of the n-shaped backing is tightly connected with the indoor side sealant and the outdoor side sealant, the waterproof mode of the waterproof and drainage device is that the water is prevented from entering through the sealant, the drainage mode of the waterproof and drainage device is that water is drained through a slope of the device, a water outlet of the waterproof and drainage device is arranged below the cross seam, the n-shaped backing is made of a foaming neoprene bar or other similar materials, and the diameter of the n-shaped backing is 1.3-1.5 times of the seam width.
Furthermore, the structure of the precast concrete external wallboard perps water-blocking and drainage device is of an n-type, the n-type backing is arranged at the vertical joint below the cross joint of the precast concrete external wallboard, the sealant is arranged at the top of the n-type backing, and the sealant at the top of the n-type backing is tightly connected with the indoor side sealant and the outdoor side sealant to form a sealed waterproof line.
Furthermore, the water blocking and draining device leads out stagnant water in the cavity of the wallboard through a slope formed by the n-shaped backing and the sealant.
Further, the material of the n-type back lining is a foaming neoprene bar or other similar materials, the diameter of the n-type back lining is 1.3-1.5 times of the seam width, and the density is 24kg/m3-48kg/m3The surface has excellent wetting property, easy adhesion, certain shaping capacity and easy manufacture.
The utility model has the advantages and the beneficial effects that: the drainage slope can accelerate the drainage of water in the cavity, reduce the amount of stagnant water in the cavity, prevent the quality of the sealant from decreasing, and has the advantages of simple and reasonable structure and convenience in installation.

Detailed Description
The invention will be further described with reference to the accompanying drawings.
As shown in figure 1, the utility model relates to a vertical seam water-blocking and draining device of a precast concrete external wall panel, which comprises an n-shaped back lining 3 and a sealant 2; the n-shaped back lining 3 is arranged between the vertical seams of the precast concrete external wall-hung panel 1; the sealant 2 is arranged on top of the n-shaped backing 3; the top sealant of the n-shaped back lining 3 is tightly connected with the indoor side sealant and the outdoor side sealant; the water outlet 4 is positioned below the cross joint of the precast concrete external wall panel 1.
After adopting above-mentioned structure, this embodiment produces beneficial effect does: the water in the drainage cavity is prevented from entering the vertical joint, the drainage of the water in the cavity can be accelerated by the arrangement of the drainage slope, the water retention in the cavity is reduced, and the quality of the sealant is prevented from being reduced; simple structure, preparation simple to operate.
While embodiments of the present invention have been presented herein, it will be appreciated by those skilled in the art that changes may be made to the embodiments herein without departing from the spirit of the invention. The above-described embodiments are merely exemplary and should not be taken as limiting the scope of the invention.
