Description

Technical Field

[0001] The present application relates to the field of building construction, and in particular to a bottom plate deformation joint structure. Background Art

[0002] In modern construction projects, buildings are affected by factors such as temperature changes and foundation settlement, which will cause different degrees of deformation. In order to prevent these deformations from causing cracks or even damage to the buildings, expansion joints are usually added to the building design to adapt to such changes.

[0003] Currently, common methods for treating base plate expansion joints include, but are not limited to, rubber waterstops, prefabricated component splicing, and elastic caulking material filling. Rubber waterstops offer excellent elasticity and sealing properties, effectively preventing water penetration, but their durability and aging resistance are relatively poor. Prefabricated component splicing, which involves on-site assembly of prefabricated components, creates expansion joints. While convenient, it lacks adaptability to varying geological conditions. Elastic caulking material filling, widely adopted for its flexibility and ease of adjustment, is susceptible to environmental factors due to long-term exposure, leading to performance degradation.

[0004] However, no matter which deformation joint treatment method is adopted, the structural strength of the deformation joint will be greatly affected due to the existence of gaps, which in turn affects the bearing capacity of the deformation joint, causing the deformation joint to be easily deformed or even collapsed when subjected to forces in all directions.

The structural plate 2 is installed on the cushion layer 1. In this embodiment, the structural plate 2 is a reinforced concrete plate. A joint 21 is formed on the structural plate 2 to provide deformation space for the structural plate 2 on both sides of the joint 21. Multiple groups of reinforcing ribs 6 are embedded in the structural plate 2 on both sides of the joint 21. Each group of reinforcing ribs 6 is bent and anchored to the steel bars of the structural plate 2. The reinforcing ribs 6 are used to specifically reinforce the structural strength of the structural plate 2 on both sides of the joint 21, thereby improving the load-bearing capacity and seismic performance of the structural plate 2 on both sides of the joint 21 and reducing the possibility of deformation or even collapse of the structural plate 2 on both sides of the joint 21.

[0034] Reference Figure 1 A rubber pad 7 is installed between the seam 21 and the structural plate 2. Through the rubber's buffering and isolation properties, the transmission of interaction force between the structural plate 2 and the pad 1 is suppressed, and the unevenness between the pad 1 and the structural plate 2 is filled, thereby improving the tightness of the contact between the pad 1 and the structural plate 2. At the same time, it can also provide a waterproof effect between the pad 1 and the structural plate 2, reducing the possibility of groundwater penetrating from the pad 1 to the structural plate 2.

[0035] Reference Figure 1 The structural plate 2 at the seam 21 extends downward and is embedded in the cushion layer 1. The part of the structural plate 2 embedded in the cushion layer 1 reduces the possibility of lateral displacement between the structural plate 2 and the cushion layer 1, and improves the stability of the structural plate 2 on the cushion layer 1.

[0040] With reference to Figure 1 , Figure 2The sealing waterstop 31 extends to both sides between the supporting angle steel 4 and the locking angle steel 51. The locking angle steel 51 clamps the sealing waterstop 31 to the supporting angle steel 4, thereby improving the stability of the sealing waterstop 31 at the connection between the upper mouth of the seam 21 and the support groove, thereby improving the sealing and waterproofing effect of the sealing waterstop 31 at the connection between the seam 21 and the support groove.
