[0032] A wall support assembly, the wall support assembly includes a first wall 101 and a second wall 102;

[0033] The first wall 101 and the second wall 102 are used to divide the entire structure;

[0034] Node assembly, the node assembly includes a drainage ditch 201, a seismic isolation ditch 202, and a horizontal seismic isolation joint 203;

[0035] The first wall 101 is located above the ground, the second wall 102 is located below the ground, a drainage ditch 201 is provided on the upper part of the second wall 102, a seismic isolation ditch 202 is provided between the left side of the first wall 101 and the right side of the second wall 102, a horizontal seismic isolation joint 203 is provided between the bottom of the first wall 101 and the top of the second wall 102, and a horizontal seismic isolation joint flexible sealing material is used to seal the horizontal seismic isolation joint (203);

[0036] The drainage ditch 201 is used to discharge rainwater from the load-bearing structure, the seismic isolation ditch 202 is used to play a role in seismic isolation, and the horizontal seismic isolation joint 203 is used as a broken bridge to disconnect the drainage ditch 201 from the above-ground building structure. The building above the horizontal seismic isolation joint 203 is a passive area, and the building below the horizontal seismic isolation joint 203 is a non-passive area. The drainage ditch 201 can ensure that rainwater is discharged in time to prevent the insulation of the outer wall of the above-ground building from being soaked by rainwater, and the horizontal seismic isolation joint flexible sealing material can effectively fill the horizontal seismic isolation joint 203;

[0037] The wall support assembly further includes a seismic isolation support 103 , a lower support pier 104 of the seismic isolation support, and an upper support pier 105 of the seismic isolation support.

[0038] The top of the seismic isolation support 103 is provided with a seismic isolation support upper pier 105, the bottom of the seismic isolation support 103 is provided with a seismic isolation support lower pier 104, and the seismic isolation support upper pier 105 is located at the bottom of the first wall 101;

[0039] The lower pier 104 of the seismic isolation support and the upper pier 105 of the seismic isolation support are used in coordination to ensure the overall seismic protection effect;

[0040] The flexible sealing material of the horizontal seismic isolation joint is firmly installed at the horizontal seismic isolation joint, and the sealant can make the sealing better;

[0041] It also includes thermal insulation and waterproofing components;

[0042] The thermal insulation and waterproof component includes a waterproof layer 501 and a thermal insulation layer 502;

[0043] A waterproof layer 501 and a thermal insulation layer 502 are sequentially arranged outside the first wall 101;

[0044] The provision of the waterproof layer 501 and the thermal insulation layer 502 further improves the waterproof effect and the thermal insulation effect;

[0045] The insulation layer 502 can be made of insulation materials according to the engineering design. In this embodiment, extruded polystyrene board is used as the insulation layer. The function of the insulation layer 502 is: as an insulation material for the exterior wall of ultra-low energy consumption buildings, it can achieve the purpose of reducing the energy consumption of the building together with the exterior wall structure. The ultra-low energy consumption building design standard requires that when the building has a basement, the exterior wall insulation should extend below the frozen soil layer. Due to the breaking bridge effect of the horizontal seismic isolation joint, the exterior wall insulation layer can meet the requirements by extending to the horizontal seismic isolation joint; the functions of the waterproof layer 501 are: 1. Protect the main structure from rain erosion, 2. Protect the insulation material to prevent the insulation material from being eroded by rain or surface water and reducing its insulation performance;

[0046] Working principle: Use sealant to adhere the flexible sealing material of the horizontal seismic isolation joint to the horizontal seismic isolation joint, and at the same time adhere the rock wool board 401 to the first wall 101;

[0047] This step can meet the design requirements of ultra-low energy consumption buildings while ensuring that the building's seismic isolation measures are not affected.

[0048] In this embodiment, the role of the flexible sealing material of the horizontal seismic isolation joint is to seal the connecting gap between the inside and the outside of the basement, and play a role of sealing and waterproofing; the role of the rock wool board is to construct an insulation layer for the above-ground heating room and the underground non-heating space. The role of the seismic isolation ditch is to work together with the seismic isolation bearing and the horizontal seismic isolation joint to meet the horizontal displacement of rare earthquakes and reduce the transmission of seismic waves to the above-ground structure; the role of the horizontal seismic isolation joint is to work together with the seismic isolation bearing and the seismic isolation ditch to meet the horizontal displacement of rare earthquakes and reduce the transmission of seismic waves to the above-ground structure. When used in ultra-low energy consumption buildings at the same time, the horizontal seismic isolation joint can play the role of breaking thermal bridges. The original ultra-low energy consumption building requires that the insulation of the basement exterior wall should extend below the frozen soil layer. Due to the breaking bridge effect of the horizontal seismic isolation joint, the extension of the exterior wall insulation to the horizontal seismic isolation joint can meet the requirements of the ultra-low energy consumption building design without thermal bridges. The function of the drainage ditch 201 is to drain rainwater around the building in time; the function of the seismic isolation bearing 103 is to provide vertical bearing capacity, so that when an earthquake occurs, the seismic isolation bearing can undergo horizontal displacement without hindrance, thereby achieving the purpose of isolating seismic energy; the lower pier of the seismic isolation bearing is a connecting part between the seismic isolation bearing and the lower structure and foundation structure, which can transmit the horizontal shear force of the lower bearing in rare earthquakes.

[0049] In the field of construction, flexible sealing materials for horizontal seismic isolation joints are usually required to have good elasticity, durability, and the ability to adapt to different environments and temperature changes, so as to ensure that the seismic isolation joints can be effectively sealed under dynamic loads such as earthquakes, prevent the intrusion of water, dust, etc., and allow necessary displacement between structural elements. In this embodiment, rubber material is selected as the flexible sealing material for horizontal seismic isolation joints.
