Embodiment 1

[0040] Embodiment 1: An external wall expansion joint structure, such as figure 1 and figure 2As shown, including the outer wall 1, the expansion joint 2, the cover plate 3 and the water stop belt 4, two bases 5 are arranged on the outer wall 1 on both sides of the expansion joint 2, and the two bases 5 are simultaneously connected by expansion bolts. Press and fix the two sides of the waterstop 4 on the outer wall 1 on both sides of the expansion joint 2 respectively. A number of sliding rods 6 are arranged at intervals along the vertical direction between the two bases 5 , and the cover plate 3 is closed on the expansion joint. 2, and both sides of the cover plate 3 are located at the outer wall 1 on both sides of the expansion joint 2, and the base 5 and the cover plate 3 are made of aluminum alloy. The cover plate 3 and the sliding rod 6 are fixed together by bolts 7 and nuts 8 , and waterproof rubber strips 9 are provided on both sides of the cover plate 3 and between t...

Embodiment 2

[0047] Embodiment 2: A method for installing an external wall expansion joint structure, comprising the following steps:

[0048] A. Clean the outer wall at the expansion joint to form the installation base;

[0049] B. Attach the waterstop to the installation base through the base glue;

[0050] C. Fix the two opposite bases on the outer walls on both sides of the expansion joint through expansion bolts;

[0051] D. Install the slide bar between the two bases, and place the cover plate, install the water-stop adhesive strip on the side wall of the base opposite the cover plate, and then fix the cover plate and the slide bar with bolts and nuts .

[0052] Double waterproofing is carried out through the water-stop strip and the water-stop rubber strip, thereby improving the waterproof performance of the expansion joint structure, and the installation of the expansion joint structure is facilitated through the above steps.

Abstract

The present invention relates to the field of building construction, more specifically, it relates to an external wall expansion joint structure. There are two bases opposite to each other on the outer wall, and the two sides of the waterstop are respectively pressed and fixed on the outer walls on both sides of the expansion joint through expansion bolts at the same time. There are several sliding rods arranged at intervals in the vertical direction. The cover plate is covered on the expansion joint, and the two sides of the cover plate are located at the outer walls on both sides of the expansion joint. The cover plate and the sliding rod are matched by bolts and nuts. Fixed, the two sides of the cover and between the two bases are respectively provided with waterproof strips. An external wall expansion joint structure of the invention has the advantage of improving waterproof performance.

Description

technical field [0001] The invention relates to the field of building construction, more specifically, it relates to an external wall expansion joint structure and an installation method thereof. Background technique [0002] Expansion joint refers to a structural joint set at an appropriate position along the construction joint direction of a building or structure in order to prevent cracks or damage to the structure due to climate temperature changes (thermal expansion, cold contraction). The expansion joint is to divide the building components above the foundation such as walls, floors, roofs (except wooden roofs) into two independent parts, so that buildings or structures can be horizontally expanded along the long direction. [0003] Expansion joint structures commonly used in exterior walls in the prior art generally include water stop strips, cover plates and bolts. When installing, first glue and fix the waterstop on the outer wall, then fix the cover plate to the o...
