Abstract
Description
Technical Field
[0001] This utility model relates to a horizontal seismic isolation joint structure, specifically an improved horizontal seismic isolation trench sealing and waterproofing structure, belonging to the field of architectural design technology. Background Technology
[0002] Current building designs often include seismic isolation layers. By installing seismic isolation rubber bearings and other technical measures, the seismic safety of building structures is improved. Seismic isolation trenches refer to the gaps between the retaining walls of the seismic isolation layer and the cover plates of the seismic isolation trenches. By setting up these horizontal seismic isolation joints, the structural parts below the seismic isolation bearings and the structural parts above the seismic isolation bearings can move up and down, left and right, and front and back during an earthquake, thereby reducing the destructive force of earthquakes on the main building structure.
[0003] In traditional designs, the horizontal seismic isolation joints of this type of seismic isolation trench are directly sealed with flexible sealant material. This sealing process must be carried out after the construction of the seismic isolation retaining wall and cover plate. The main drawbacks of this design are: ① Difficult construction: During construction, the sealant often has defects such as incomplete application and lack of density; ② Weak waterproofing and insufficient durability: Due to the frequent defects in the sealant, the horizontal seismic isolation joints are prone to seepage and leakage, requiring regular maintenance and even repairs; ③ In summary, the traditional design for sealing horizontal seismic isolation joints in seismic isolation trenches suffers from significant labor waste, poor waterproofing performance, poor durability, and increased costs associated with later construction, maintenance, and repairs.
[0004] Although existing structures already incorporate corresponding sealing and waterproofing mechanisms, they still suffer from structural complexity, long construction periods, and high costs.
[0005] Therefore, the key to solving the above-mentioned technical problems lies in developing a simple-to-construct, waterproof horizontal seismic isolation joint sealing and waterproofing structure and its construction method. Utility Model Content
[0006] In view of the many defects and shortcomings existing in the above-mentioned background technology, this utility model has made improvements and innovations, aiming to provide a new type of horizontal seismic isolation joint structure with simple structure and ingenious design, which can improve the waterproof performance of the horizontal seismic isolation joint and the overall construction quality of the seismic isolation trench while achieving the good effects of reducing labor efficiency and saving costs.
[0007] To solve the above problems and achieve the above-mentioned utility model objectives, this utility model provides an improved horizontal seismic isolation joint sealing and waterproofing structure for seismic isolation trenches, achieved through the following design structure and the following technical solution:

[0009] Waterstop strips are symmetrically installed on both sides of the top of the retaining wall of the seismic isolation trench.

[0011] Waterstop strip: One end of the waterstop strip is placed inside the upper part of the retaining wall of the seismic isolation trench, and the other end is placed inside the cover plate of the seismic isolation trench.
[0012] The waterstop strip and asphalt sealant are tightly installed between the retaining wall of the seismic isolation trench and the cover plate of the seismic isolation trench.
[0013] Preferably, the waterstop strip is a water-swellable waterstop strip.
[0014] Preferably, the lower half of the waterstop is installed and fixed in the middle of the retaining wall of the seismic isolation trench, and the upper half of the waterstop is installed and fixed in the cover plate of the seismic isolation trench. The middle part of the waterstop is located at the top of the retaining wall of the seismic isolation trench and in the middle of the asphalt paste.
[0015] Preferably, the waterstop is a rubber waterstop.
[0016] Preferably, the waterstop strip is made of a flexible material.
[0017] Preferably, the asphalt paste is a flexible material.
[0018] Preferably, the waterstop is made of a flexible material.

The overall construction process is simple to operate, the quality is controllable, and the safety and reliability are guaranteed.
[0023] 4. While satisfying the structural functions (horizontal seismic isolation joints can expand and shift during earthquakes) and usability of traditional seismic isolation trenches and horizontal seismic isolation joints, this utility model effectively improves the waterproofness, durability, and applicability of the horizontal seismic isolation joint structure.

[0042] Before using the above-mentioned improved horizontal seismic isolation joint sealing and waterproofing structure of the seismic isolation trench, it needs to be installed as a backup.
[0043] As per the instruction manual Figures 2 to 8 As shown, an improved horizontal seismic isolation joint sealing and waterproofing structure for seismic isolation trenches is characterized by comprising:
[0044] Waterstop strip 1 is symmetrically installed on both sides of the top of the retaining wall 4 of the seismic isolation trench;

[0046] Waterstop 3, one end of which is set inside the retaining wall 4 above the seismic isolation trench, and the other end is set inside the cover plate 5 of the seismic isolation trench;
[0047] Among them, the waterstop strip 1 and the asphalt paste 2 are tightly installed between the retaining wall 4 of the seismic isolation trench and the cover plate 5 of the seismic isolation trench.
[0048] Furthermore, the waterstop strip 1 is a water-swellable waterstop strip.
[0049] Furthermore, the waterstop 3 is a rubber waterstop.
[0050] Specifically, the lower half of the waterstop 3 is installed and fixed in the middle of the retaining wall 4 of the seismic isolation trench, and the upper half of the waterstop 3 is installed and fixed in the cover plate 5 of the seismic isolation trench. The middle part of the waterstop 3 is located at the top of the retaining wall 4 of the seismic isolation trench and in the middle of the asphalt paste 2.
[0051] Furthermore, the waterstop strip 1, asphalt paste 2, and waterstop belt 3 are all made of flexible materials.
[0052] like Figures 1 to 8 As shown, the working process of this improved horizontal seismic isolation joint sealing and waterproofing structure includes the following steps:
[0053] S1, Construction of the foundation or base slab structure of the seismic isolation layer;
[0054] S2. After the construction of the foundation or base plate structure of the seismic isolation layer is completed, the reinforcement and formwork of the seismic isolation trench retaining wall are installed.

[0055] After the installation of the reinforcement, formwork and waterstop of the retaining wall of the seismic isolation trench is completed, the concrete of the retaining wall of the seismic isolation trench is poured.
[0056] S4. After the construction of the seismic isolation trench retaining wall 4 is completed, the waterstop strip 1 is installed parallel to the top two sides of the seismic isolation trench retaining wall 4. After the waterstop strip 1 is installed, the asphalt paste 2 is filled between the waterstop strip 1 and the waterstop strip 3.

[0057] After the construction of the waterstop strip 1 and asphalt paste 2 at the top of the seismic isolation trench retaining wall 4 is completed, the construction of the seismic isolation trench cover plate reinforcement and formwork is carried out. During this period, the upper part of the waterstop strip 3 needs to be pre-embedded and fixed inside the seismic isolation trench cover plate 5.
[0058] S6, After the installation of the upper part of the reinforcement, formwork and waterstop of the seismic isolation trench cover plate is completed, pour the concrete for the seismic isolation trench cover plate.

[0060] Furthermore, in step S5, the waterstop strip 1 and asphalt sealant 2 on the top of the seismic isolation trench retaining wall can be used to replace the bottom formwork of the corresponding area during the installation of the seismic isolation trench cover plate template 5.
