[0027] The following is combined with Figure 1 -Attached Figure 3 This application is described in further detail.

[0028] The embodiment of the present application discloses a building seismic isolation trench.

[0029] Example 1

[0030] Reference Figure 1 A seismic isolation trench for a building is arranged outside a frame column 1, a frame beam 2 is arranged on the top of the frame column 1 located above, an underground retaining wall 3 is arranged outside the frame column 1 located below, and a seismic isolation support 4 is arranged between the upper and lower frame columns 1. The seismic isolation trench for a building includes a foundation pit fertilizer trough backfill layer 5, a concrete cushion layer 6, a waterproof layer 7 and a seismic isolation trench retaining wall 8, which are arranged from bottom to top on the outside of the underground retaining wall 3, wherein the waterproof layer 7 includes a flexible waterproof layer 70 connected to the concrete cushion layer 6 and a waterproof protective layer 71 connected to the seismic isolation trench retaining wall 8.

[0031] Reference Figure 1 and Figure 2 The seismic isolation trench retaining wall 8 is connected to the underground retaining wall 3 through a connecting assembly 9, which includes a fixing plate 90 vertically fixed to the outer vertical wall of the underground retaining wall 3. The fixing plate 90 is a steel plate. A plurality of steel sleeves 91 are fixedly connected to the side of the fixing plate 90 close to the underground retaining wall 3. The steel sleeves 91 are provided with internal threads. Pre-embedded steel bars 92 are threadedly connected to the steel sleeves 91. The pre-embedded steel bars 92 are L-shaped and are pre-embedded in the underground retaining wall 3. The steel bars in the seismic isolation trench retaining wall 8 are distributed steel bars 93, which are threadedly connected to the other end of the steel sleeves 91, so that the pre-embedded steel bars 92 and the distributed steel bars 93 are butt-connected through the steel sleeves 91.

[0032] The implementation principle of Example 1 is as follows: during construction, the embedded steel bars 92 are first installed on the steel bar sleeve 91, and then the fixing plate 90 is cast on the underground retaining wall 3, so that the steel bar sleeve 91 and the embedded steel bars 92 are cast in the underground retaining wall 3, and then the distribution steel bars 93 are threadedly installed on the steel bar sleeve 91, and then the seismic isolation trench retaining wall 8 is cast. The new seismic isolation trench method is adopted, so that the embedded steel bars meet the anchoring requirements, no planting of steel bars is required, and the operation is simple.

[0033] Example 2

[0034] Reference Figure 3 The difference between this embodiment and embodiment 1 is that a second steel sleeve 94 is fixedly connected to the position of the first steel sleeve 91 on the outer side of the fixed plate 90, a retaining ring 95 is fixedly mounted on the distribution steel bar 93, and a mounting cap 96 is movably mounted on the distribution steel bar 93. The distribution steel bar 93 is threadedly connected to the second steel sleeve 94, the retaining ring 95 abuts against one end of the second steel sleeve 94 away from the fixed plate 90, and the mounting cap 96 is threadedly mounted on the second steel sleeve 94.

[0035] The implementation principle of Example 2 is as follows: the construction personnel install the distribution steel bar 93 on the second steel bar sleeve 94, make the retaining ring 95 abut against the second steel bar sleeve 94, and install the installation cap 96 on the second steel bar sleeve 94, thereby completing the installation of the distribution steel bar 93. This installation method is simple and convenient. When pouring the underground retaining wall 3, the threaded cap can be firstly sleeved on the second steel bar sleeve 94 to prevent concrete and other impurities from entering the second steel bar sleeve 94 and affecting the subsequent installation of the distribution steel bar 93. After the underground retaining wall 3 is poured, the distribution steel bar 93 is installed in the second steel bar sleeve 94, and the installation cap 96 is screwed to further complete the fixation, effectively improving the firmness of the distribution steel bar 93 after installation.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
