Problems solved by technology

With the alternation of temperature, the thermal expansion and contraction of objects, the uneven settlement of the foundation and the influence of external force majeure and other factors will cause the deformation of the expansion joints of the building, and the materials of conventional expansion joints cannot adapt well to the outside world. Changes in the environment, and there is no certain activity margin, the most likely to cause water leakage

Embodiment 1

[0017] The expansion joints to be constructed in this embodiment are "inline", such as figure 1 As shown, its construction process includes the following process steps:

[0018] 1) Reservation of expansion joint accessories: Before the plastering project, the actual length of the expansion joint must be measured, and the overlapping and loss of various profiles must be calculated.

[0019] 2) Acceptance inspection of wall plastering at expansion joints: Before construction and installation, the plastering layer on the wall must be inspected to ensure the flatness and verticality of the wall 8 and ensure that the wall 8 has no hollows, crack.

[0020] 3) Construction setting out on both sides of the expansion joint: before installation, the position of the 8 expansion joints on the wall and the layout of the arrangement of the fixed points of the sliders should be prepared in advance. Carry out on-site laying-out according to the plank layout. After cleaning the part to be se...

Embodiment 2

[0029] The expansion joint to be constructed in this embodiment is "L-shaped", such as figure 2 As shown, its construction process includes the following process steps:

[0030] 1) Reservation of expansion joint accessories: Before the plastering project, the actual length of the expansion joint must be measured, and the overlapping and loss of various profiles must be calculated.

[0031] 2) Acceptance inspection of wall plastering at expansion joints: Before construction and installation, the plastering layer on the wall must be inspected to ensure the flatness and verticality of the wall 8 and ensure that the wall 8 has no hollows, crack.

[0032] 3) Construction setting out on both sides of the expansion joint: before installation, the position of the 8 expansion joints on the wall and the layout of the arrangement of the fixed points of the sliders should be prepared in advance. Carry out on-site laying-out according to the plank layout. After cleaning the part to be s...

Abstract

The invention discloses an expansion joint-adjustable dual-waterproof installation construction process, comprising the following process steps of: plastering wall surfaces positioned on the expansion joint; carrying out construction measurement on both sides of the expansion joint; adhering waterstops; installing and fixing an aluminum alloy base; sizing the edges of the aluminum alloy base; embedding rubber strips; assembling and fixing a slide rod and a cover plate; processing the expansion joint, and cleaning an exterior. The invention has the advantages of firm installation, dual waterproofing, large expansion amount and elegant appearance without the raised margins of the cover plate.

Description

technical field [0001] The invention relates to an adjustable double waterproof installation construction technology for expansion joints. Background technique [0002] With the rapid development of my country's construction industry, not only are the heights of buildings springing up like mushrooms after rain, but also the length is getting longer and longer, with more and more expansion joints. With the alternation of temperature, the thermal expansion and contraction of objects, the uneven settlement of the foundation and the influence of external force majeure and other factors will cause the deformation of the expansion joints of the building, and the materials of conventional expansion joints cannot adapt well to the outside world. Changes in the environment, and there is no certain activity margin, the most likely to cause water leakage. Contents of the invention [0003] The object of the present invention is to provide an adjustable double waterproof installation...
