Embodiment 1

[0017] Both sides of the building expansion joints in this embodiment are planes, such as figure 2 As shown, its construction process includes the following process steps:

[0018] Before the construction of the project, the actual length of the expansion joint must be measured and the loss amount calculated. Before construction and installation of building expansion joints, it is necessary to ensure that the construction of the previous project has been completed, and there are no quality problems that affect the later construction (expansion joint construction), and make sure that the verticality and flatness of the wall and ground meet the requirements.

[0019] Construct the gap of the construction process of the expansion joint between the main body of the building and the steps. When building the steps of the building, reserve or cut out the gap of the expansion joint. The width of the gap is smaller than the width of the strip 1; clean up after the construction Debris...

Embodiment 2

[0024] In this embodiment, one side of the building expansion joint is a plane, and the other side is a facade, such as image 3 As shown, its construction process includes the following process steps:

[0025] 1) Construct the gap between the main body of the building and the steps of the expansion joint construction process. When building the steps of the building, reserve or cut out the gap of the expansion joint. The width of the gap is smaller than the width of the strip (1) . Before construction and installation of building expansion joints, it is necessary to ensure that the construction of the previous project has been completed, and there are no quality problems that affect the later construction (expansion joint construction), and make sure that the verticality and flatness of the wall and ground meet the requirements;

[0026] 2) Gap treatment of construction expansion joints: This process needs to complete the treatment of the foundation of construction expansion ...

Abstract

The invention discloses a construction process of an expansion joint between a building main body and a step, and the construction process belongs to the field of building construction. A gib made of an aluminum alloy material is embedded into the expansion joint; the cross section of the gib is in a K shape; a transverse stripe is arranged at the upper part of the gib; a plane with slopes at the edges is arranged on the upper surface of the transverse stripe; a C-shaped opening is arranged at the lower part of the gib; and an elastic rubber strip is embedded into the C-shaped opening. A transverse slot is formed on the building main body on one side of the expansion joint, or on the elevation of the step. After the expansion joint is cleaned, neutral silicone adhesive is injected to the bottom of the joint, and then the gib is embedded into the expansion joint of a building, and bonded by 1:1 asphaltic sand or the neutral silicone adhesive. With the adoption of the construction process of the expansion joint between the building main body and the step, the expansion joint is more attractive in appearance, can expand and contract naturally in winter and summer, is tightly sealed, and has a better water proof effect.

Description

technical field [0001] The invention relates to a building construction process, in particular to an expansion joint of a building and its construction process. Background technique [0002] At present, in the construction industry, no matter whether it is cement floor and wall or marble and other stone materials, it involves the problem of leaving expansion joints. Expansion joints are generally used to reserve gaps between buildings during construction, or cut out gaps, and then fill the gaps with asphalt. This method not only has poor waterproof performance, but also has an unattractive appearance, and there are later repairs. difficult question. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an expansion joint with convenient construction, beautiful appearance and no maintenance and its construction process. [0004] In order to solve the above technical problems, the technical solution adopted in the pres...
