Construction method of prefabricated concrete building prefabricated outer wall abutted seam drainage pipe

Abstract

The invention discloses a construction method of a prefabricated concrete building prefabricated outer wall abutted seam drainage pipe, and belongs to the technical field of building construction. The construction method for the prefabricated concrete building prefabricated outer wall abutted seam drainage pipe is realized based on construction glue sealing equipment for the prefabricated concrete building prefabricated outer wall abutted seam drainage pipe, the construction glue sealing equipment for the prefabricated concrete building prefabricated outer wall abutted seam drainage pipe involves a wall body, the output end of a motor penetrates through the interior of a fixing lug, extends to the exterior and is coaxially connected to a cylinder, through cooperation of a cylindrical cam and tight cooperation of a scraper rotationally connected to the middle of the rear side of a adjusting block through a hinge pin, laitance cannot be splashed and adhered to the outer side of a joint part when laitance is poured, the situation that the laitance splashes and is not easy to clear, and the integrity and attractiveness of the wall body are influenced is avoided, meanwhile, the situation that manual scraping is tedious and uneven is avoided, scraping is conducted through the automatic scraper, and the whole body is smoother and can be integrated with the whole wall body.

Description

technical field [0001] The invention relates to the technical field of building construction, and more specifically, relates to a construction method for a spliced ​​joint drainage pipe on a prefabricated exterior wall of a prefabricated concrete building. Background technique [0002] In the waterproof system of the prefabricated external walls of prefabricated concrete buildings, the design concept is always that drainage is better than water blocking. Therefore, in order to realize the integrity of the waterproof function of the building, the drainage function of the cavity must be realized. However, today’s prefabricated concrete buildings Drainage is still not enough attention, and most of the waterproof function of buildings is entrusted to the waterproofing of materials. However, when the temperature inside and outside the drainage cavity is inconsistent, condensed water may be generated in the cavity, and even when the sealant of the outer wall is damaged or the bondi...

Problems solved by technology

The foam strips are placed in the joints of the prefabricated external walls and the sealing layer is set to form a drainage cavity. The water flows into the joints of the prefabricated external walls and flows down along the foam strips. Using the principle of one-way drainage of the drainage pipes, the drainage cavity is divided due to The condensed water generated when the internal and external temperatures are not consistent is discharged. Although this device has many beneficial effects, the following problems still exist: this method manually puts the laitance into the seam, and it is easy to cause the laitance to splash out and adhere to the outside of the seam It is extremely difficult to clean, and it is difficult to ensure that the outside of the joint is smooth and clean, and it is difficult to ensure that the outside of the joint is flat and clean.
