Abstract

The utility model provides a precast concrete cladding board drainage structure, including precast concrete cladding board, backer strip, sealed glue, drainage cavity, drainage groove, drainage slope and outlet. The precast concrete cladding panel is provided with a tongue-and-groove at the top and the bottom of the panel; the top of the precast concrete cladding panel is provided with a drainage groove which is communicated along the length direction of the panel; the water outlet is used for guiding water through the water drainage slope; the water outlet is arranged below the cross joint of the precast concrete cladding panel; the drainage cavity is formed by two precast concrete cladding panels, sealing glue and sealing glue in a surrounding mode. The utility model has the advantages that: the arrangement of the drainage groove can assist the drainage cavity in reducing the water retention amount and accelerating drainage, and can also prevent unsmooth drainage caused by uneven top of the external hanging plate; the precast concrete cladding panel does not need the recess then at vertical side, convenient construction.

Description

Precast concrete cladding board drainage structure

Technical Field

The utility model relates to an assembly building construction technical field, in particular to precast concrete cladding board drainage structure.

Background

The prefabricated concrete wall panels are produced in factories in an industrialized mode, have the advantages of high construction speed, good quality and low maintenance cost, and are also more and more widely applied to various buildings.

For fabricated buildings, the treatment of staggered splice seams on exterior wall panels is one of the difficulties in waterproofing. The drainage of the splicing seams is one of waterproof keys, and the sealing quality of the waterproof sealant is reduced or even the sealing is failed due to excessive and long-term retention of water in the splicing seams, so that the water drainage construction method of the exterior cladding panel can directly influence the waterproof quality of building products.

SUMMERY OF THE UTILITY MODEL

The utility model aims at avoiding the drainage construction method improper, providing a precast concrete cladding drainage structure.

The utility model relates to a drainage structure of precast concrete cladding, including precast concrete cladding, backer strip, sealed glue, outlet, drainage groove and drainage cavity. The precast concrete cladding panel is provided with a tongue-and-groove at the top and the bottom of the panel; the top of the precast concrete cladding panel is provided with a drainage groove which is communicated along the length direction of the panel; the water outlet is arranged below the cross joint of the precast concrete cladding panel; the drainage cavity is formed by two precast concrete cladding panels, sealing glue and sealing glue in a surrounding mode.

Furthermore, the precast concrete cladding panel is provided with a tongue-and-groove at the top and the bottom of the panel, and a horizontal drainage cavity in a high-low seam type is formed by matching sealant and a backing strip.

Furthermore, a drainage groove is formed in the top of the precast concrete cladding panel and penetrates through the precast concrete cladding panel along the length direction of the panel; the cross section of the drainage groove is rectangular; the drainage groove is close to the bottom of the rabbet and used for collecting and discharging stagnant water from the rabbet or the top of the external hanging plate.

Furthermore, the water outlet leads out the stagnant water in the water drainage cavity through a water drainage slope formed by the backing strip and the sealant.

Furthermore, the backing strip and the sealant form two waterproof lines on two sides of the drainage cavity.

The utility model has the advantages and the beneficial effects that: the arrangement of the drainage groove can assist the drainage cavity in reducing the water retention amount and accelerating drainage, and can also prevent unsmooth drainage caused by uneven top of the external hanging plate; the precast concrete cladding panel does not need the recess then at vertical side, convenient construction.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1, the utility model relates to a precast concrete cladding panel drainage structure, which comprises a precast concrete cladding panel 1, backing strips 2, sealant 3, drainage grooves 4, drainage cavities 5, cast-in-place concrete layers 6, precast composite floor slabs 7, beams 8, drainage slopes 9 and a drainage outlet 10; the drainage groove 4 is positioned at the top of the precast concrete cladding panel and is close to the bottom of the tongue-and-groove of the cladding panel; the sealant 3 is arranged on two sides of the drainage cavity 5 and is respectively contacted with the external environment of the building and the internal environment of the cavity.

As shown in fig. 2, the sealant 3 is used for sealing construction after all the precast concrete external wall panels 1 are corrected and installed; the sealant 3 should be applied after the backing strip 2 is caulked.

As shown in fig. 3, the water outlet 10 is arranged below the cross joint of the precast concrete cladding 1; the water outlet 10 is provided with a water discharge slope 9;

as shown in fig. 3, the drainage ramp 9 is formed by the backing strip 2 and the sealant 3; the drainage ramp 9 should not exceed the drainage groove 4 cross-section after the application of glue.

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.
