Abstract
Assembled building outer wall drainage structure, including vertical main drain pipe, main drain pipe rear side is equipped with a plurality of first through-holes, is equipped with a plurality of horizontal branch pipes on the main drain pipe, and the branch pipe rear side is equipped with a plurality of second through-holes, and main drain pipe and branch pipe are the polyethylene hose. The construction method comprises the following steps: the main drainage pipe is positioned in a longitudinal joint of an outer wall of the fabricated building, a branch pipe is arranged in a transverse joint communicated with the longitudinal joint on the outer wall, the branch pipe is communicated with the main drainage pipe, a sewer pipe near the outer wall of the building is led into the lower side of the main drainage pipe, and finally building weather-resistant glue is filled in the longitudinal joint and the transverse joint. This structure can be smoothly with the clearance water discharge in the assembly type structure gap, prevents the outer wall infiltration. The construction method has simple steps, convenient construction and good drainage effect.
Description
Technical Field
The invention relates to an external wall drainage structure of an assembly type building and a construction method thereof.
Background
The assembly type building outer wall is mostly "sandwich" structure, and the prefabricated outer wall of sandwich insulation board is all adopted to standard layer outer wall, and precast concrete is excessive with cast-in-place concrete joint, and in the assembly type high-rise building sandwich insulation board outer wall construction process, it is many because of the board seam is reserved to the outer wall, generally adopts polyethylene foam stick inside lining to add building resistant weather to glue to handle in follow-up work progress, has a large amount of infiltration hidden dangers. The main disadvantages are: firstly, the polyethylene foam rod is easy to absorb water and store water, cannot effectively drain water and only plays a lining effect; and once the outer wall has a water seepage point, the seepage water cannot be discharged from the heat insulation layer, and the seepage water pressure can be formed in the heat insulation layer after the seepage water is accumulated for a long time, so that the seepage water easily penetrates into the room from concrete gaps and inner hole holes blocked by cement mortar.
Disclosure of Invention
The first technical problem to be solved by the invention is to provide an outer wall drainage structure of a fabricated building, which can smoothly drain gap water in a gap of the fabricated building and prevent water seepage of the outer wall.
The second technical problem to be solved by the invention is to provide the construction method of the assembled building outer wall drainage structure, which has the advantages of simple steps, convenient construction and good drainage effect.
In order to solve the first technical problem, the invention provides an assembled building outer wall drainage structure which comprises a main drainage pipe vertically arranged, wherein a plurality of first through holes penetrating through the main drainage pipe in the front-back direction are formed in the rear side of the main drainage pipe, a plurality of branch pipes horizontally arranged are arranged on the main drainage pipe and communicated with the main drainage pipe, a plurality of second through holes penetrating through the main drainage pipe in the front-back direction are also formed in the rear side of each branch pipe, and the main drainage pipe and the branch pipes are hoses made of polyethylene materials.
Preferably, the pitch of the first through holes on the main drainage pipe is 50cm, and the pitch of the second through holes on the branch pipe is 50 cm.
For the sake of simplicity of explanation, the drainage structure for the exterior wall of the prefabricated building according to the present invention is hereinafter referred to simply as the present structure.
The advantage of this structure: this structure can be smoothly with the clearance water discharge in the assembly type structure gap, prevents the outer wall infiltration.
In order to solve the second technical problem, the invention provides a construction method of an outer wall drainage structure of an assembly type building, which comprises the following steps:
(1) positioning the main drainage pipe in a longitudinal joint of an outer wall of the fabricated building, and ensuring that the first through hole is arranged towards the inner side of the longitudinal joint;
(2) arranging branch pipes in transverse seams communicated with the longitudinal seams on the outer wall, and ensuring that the second through holes are arranged towards the inner sides of the transverse seams;
(3) and communicating the branch pipes with the main drainage pipe, guiding the lower side of the main drainage pipe into a sewer pipe near the outer wall of the building, and finally filling the building weather-resistant glue into the longitudinal joints and the transverse joints.
For the sake of simplicity of explanation, the construction method of the drainage structure of the exterior wall of the prefabricated building according to the present invention is simply referred to as the present method.
The method has the advantages that: the method has simple steps, convenient construction and good drainage effect.

Fig. 3 is a sectional view B-B of fig. 1.
Detailed Description
Referring to fig. 1-3, the assembled building outer wall drainage structure comprises a main drainage pipe 1 which is vertically arranged, a plurality of first through holes 11 which penetrate through the main drainage pipe 1 along the front-back direction are formed in the rear side of the main drainage pipe 1, a plurality of branch pipes 2 which are horizontally arranged are arranged on the main drainage pipe 1, the branch pipes 2 are communicated with the main drainage pipe 1, a plurality of second through holes 21 which penetrate through the main drainage pipe 1 along the front-back direction are also formed in the rear side of the branch pipes 2, and the main drainage pipe 1 and the branch pipes 2 are hoses made of polyethylene materials.
The pitch of the first through holes 11 on the main drainage pipe 1 is 50cm, and the pitch of the second through holes 21 on the branch pipe 2 is 50 cm.
The advantage of this structure: this structure can be smoothly with the clearance water discharge in the assembly type structure gap, prevents the outer wall infiltration.
The construction method of the outer wall drainage structure of the fabricated building comprises the following steps:
(1) positioning the main drainage pipe 1 in a longitudinal joint of an outer wall of the fabricated building, and ensuring that the first through hole 11 is arranged towards the inner side of the longitudinal joint;
(2) arranging a branch pipe 2 in a transverse seam communicated with the longitudinal seam on the outer wall, and ensuring that the second through hole 21 is arranged towards the inner side of the transverse seam;
(3) and (3) communicating the branch pipes 2 with the main drainage pipe 1, guiding the lower side of the main drainage pipe 1 into a sewer pipe near the outer wall of the building, and finally filling building weather-resistant glue into the longitudinal joints and the transverse joints.
The method has the advantages that: the method has simple steps, convenient construction and good drainage effect.
