Description

Technical Field

[0001] The utility model belongs to the technical field of building engineering, and more specifically relates to a node structure for connecting a building partition wall and a floor at a ground seismic isolation joint. Background Art

[0002] For buildings that use underground seismic isolation technology, in addition to the underground seismic isolation layer needing to meet the corresponding requirements, the seismic joints between the above-ground part and the adjacent building units must also meet the corresponding seismic isolation requirements, which are now commonly known as "seismic isolation joints". The current standards provide some construction methods for the main seismic isolation joints between the above-ground building units and the connection methods for the internal and external partition walls of the buildings on both sides of the seismic isolation joints, so as to ensure that the main body and building partition walls on both sides of the seismic joints can move freely horizontally during an earthquake, thereby achieving the purpose of seismic isolation.

[0003] However, the total widths required for the corresponding seismic isolation components in the above-mentioned "some structural practices for the main seismic isolation joints between ground building units" and "connection practices for internal and external partition walls of buildings on both sides of the seismic isolation joints" are also different. The two cannot be effectively connected, and the current standard does not provide practices for connecting the building partition walls and floors. As a result, the partition walls and floors at the ground seismic isolation joints may not be able to achieve the ideal seismic isolation effect, and indirectly affect the applicability of the national standard drawings at this location.

DETAILED DESCRIPTION

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] See also Figures 1 to 3 , the node structure for connecting the building partition wall and the floor at the ground isolation joint provided by the utility model is now described. The node structure for connecting the building partition wall and the floor at the ground isolation joint comprises a floor body 1, a building partition wall 2 and an isolation structure; there is an isolation joint 3 between two adjacent floor bodies 1; the upper end of the floor body 1 is provided with a cantilever structure 4 extending toward the isolation joint 3, and the cantilever structure 4 is connected to the building partition wall 2; the cantilever structure 4 cooperates with the floor body 1 to form a horizontal joint 6 opening toward the isolation joint 3; the isolation structure comprises an isolation component 10 covering the isolation joint 3, and both sides of the isolation component 10 extend into the horizontal joints 6 on both sides of the isolation joint 3, and there is movable space above and to the side of the isolation component 10.

[0023] The utility model provides a node structure for connecting building partition walls and floors at ground seismic isolation joints. Compared with the prior art, a cantilever structure 4 is arranged at the edge of the floor body 1 near the seismic isolation joint 3, and the building partition wall 2 is partially lifted up by the cantilever structure 4 to form a horizontal joint 6. The seismic isolation structure is separated from the building partition wall 2 up and down by means of the horizontal joint 6. When an earthquake occurs, the seismic isolation component 10 is not directly pressed or hindered by the building partition wall 2, which ensures that the seismic isolation component 10 can slide freely within the range of the horizontal joint 6, so that the seismic isolation building can exert the seismic isolation effect and ensure the safety of the building during an earthquake.

[0024] Specifically, the horizontal distance between the closed end of the horizontal slit 6 formed by the cantilever structure 4 and the seismic isolation component 10 is greater than or equal to the width of the seismic isolation slit 3. To ensure the seismic isolation effect, the horizontal length of the horizontal slit 6 must be greater than or equal to the length of the seismic isolation component 10 extending into the horizontal slit 6, that is, to leave movable space for the horizontal movement of the seismic isolation component 10.

[0025] Due to the existence of the seismic isolation joint 3, the seismic isolation component 10 overlapped on the seismic isolation joint 3 will slide horizontally with the shaking of the floor body 1 during an earthquake, and the sliding distance is limited by the width of the seismic isolation joint 3, and the maximum is the width of the seismic isolation joint 3. Therefore, when the seismic isolation component 10 is not displaced, the distance between its end and the closed end of the horizontal joint 6 is greater than or equal to the width of the seismic isolation joint 3, leaving enough space for the displacement of the seismic isolation component 10.

[0026] Optionally, glass wool felt and waterproof membrane are sequentially arranged inside the seismic isolation joint 3 from bottom to top, and the upper end surface of the waterproof membrane is lower than the upper end surface of the floor body 1. The seismic isolation component 10 is overlapped on the upper end of the floor body 1, and covers the top of the waterproof membrane in the seismic isolation joint 3. The seismic isolation component 10 generally adopts a metal cover plate, and a free sliding space coordinated with the width of the seismic isolation joint 3 is extended on both sides of the seismic isolation joint 3. The seismic isolation component 10 covers the seismic isolation joint 3 and extends into the horizontal joint 6. While closing the seismic isolation joint 3 and ensuring the building function at ordinary times, it can also ensure that the seismic isolation building can be freely displaced during an earthquake to ensure the seismic isolation effect.

[0027] In order to ensure that the seismic isolation component 10 in the horizontal seam 6 will not be directly pressed or obstructed by the building partition wall 2 or the cantilever structure 4 above it, the vertical distance between the upper end of the horizontal seam 6 and the upper end surface of the seismic isolation component 10 is greater than or equal to twice the thickness of the seismic isolation component 10. The vertical seam width of the horizontal seam 6 is greater than the height of the seismic isolation component 10, and it is mainly used to leave room for the up and down movement of the seismic isolation component 10 and its horizontal free sliding. However, in order to facilitate installation and ensure its functionality, the vertical seam width of the horizontal seam 6 is retained at least twice the thickness of the seismic isolation component 10. The vertical seam width of the horizontal seam 6 is the distance between the lower end surface of the protruding part of the cantilever structure 4 and the upper end surface of the floor main body 1.

[0028] In some possible embodiments, see Figure 1 The cantilever structure 4 is an L-shaped component, and the cantilever structure 4 includes a first supporting portion 11 and a second supporting portion 12; the first supporting portion 11 is longitudinally arranged and fixedly connected to the upper end surface of the floor body 1; the second supporting portion 12 is vertically connected to the upper end of the first supporting portion 11, and the second supporting portion 12 extends horizontally to above the horizontal seam 6; a horizontal seam 6 is formed between the second supporting portion 12 and the floor body 1.

[0029] The first support part 11 and the second support part 12 are both plate-like structures. The first support part 11 is arranged longitudinally, and its lower end is connected to the floor main body 1. The side of the first support part 11 facing the seismic isolation joint 3 forms a horizontal joint 6 with the help of the floor main body 1 and the second support part; the side of the first support part 11 away from the horizontal joint 6 is connected to the building partition wall 2. The second support part 12 is arranged transversely, and is vertically connected to the upper end of the first support part 11, and extends toward one side of the seismic isolation joint 3 to form a cantilevered part of the cantilevered structure 4. The end of the cantilevered part of the cantilevered structure 4 extends to be flush with the edge of the seismic isolation joint 3. The lower end surface of the second support part 12 forms the top surface of the horizontal joint 6, and the upper end surface of the second support part 12 is connected to the lower end surface of the building partition wall 2. The second support part 12 cooperates with the first support part 11 to form the cantilevered structure 4, and a horizontal joint 6 is formed between the cantilevered part of the cantilevered structure 4 and the upper end surface of the floor main body 1.

[0030] The cross-sections of the first support portion 11 and the second support portion 12 of the cantilever structure 4 are both rectangular. The cantilever structure 4 is generally made of cast-in-place reinforced concrete to support the building partition wall 2; that is, the first support portion 11 and the second support portion 12 can be directly cast in-place. The thickness of the first support portion 11 of the cantilever structure 4 is consistent with the thickness of the second support portion 12. The width of the first support portion 11 of the cantilever structure 4 is consistent with the width of the second support portion 12, and both are equal to the thickness of the building partition wall 2.

[0031] The main floor body 1 is a beam-slab member, which is a reinforced concrete member. During construction, the main floor body 1 serves as a base for the cantilever structure 4 and is used to support the cantilever structure 4 and the building partition wall 2.

[0032] The building partition wall 2 is a lightweight wall used to separate building rooms. It is disconnected when encountering the seismic isolation joint 3. At the seismic isolation component 10 and the horizontal joint 6, the lower end of the building partition wall 2 is attached to the cantilever structure 4.

[0033] A structural column 5 is connected to one side of the building partition wall 2 near the seismic isolation joint 3, and the structural column 5 is located at the upper end of the cantilever structure 4. That is, the structural column 5 is located between the floor partition wall and the seismic isolation joint 3, and is used to strengthen the stability of the floor partition wall. The structural column 5 is mostly made of reinforced concrete structure.

[0034] In some possible embodiments, see Figure 1The seismic isolation structure located at the seismic isolation joint 3 also includes a supporting member 8, which is used to support and connect the seismic isolation component 10; the lower end of the supporting member 8 is connected to the upper end surface of the floor body 1, and the upper end of the supporting member 8 is slidably matched with the seismic isolation component 10.

[0035] The supporting member 8 includes a lower transverse plate, an upper transverse plate and a connecting plate. The lower transverse plate is connected to the upper end surface of the floor body 1; the upper transverse plate is parallel to the lower transverse plate, and the upper end of the upper transverse plate is connected to the lower end surface of the seismic isolation component 10; the connecting plate is used to connect the lower transverse plate and the upper transverse plate.

[0036] The support member 8 can be made of metal material, such as aluminum alloy; the lower transverse plate and the upper transverse plate of the support member 8 form a Z-shaped structure with the help of the connecting plate, and the support member 8 supports and connects the seismic isolation component 10 through the Z-shaped structure. The lower transverse plate is attached to the upper end surface of the floor body and is fixed to the floor body with the help of bolts and other connecting parts; the upper transverse plate is located above the floor body, and the upper transverse plate is attached to the lower end surfaces of the two side parts of the seismic isolation component 10, which is used to support the edge part of the seismic isolation component 10. Optionally, the seismic isolation component 10 is laterally overlapped on the two support members 8 on both sides of the seismic isolation joint 3, and has the freedom to slide horizontally.

[0037] A building surface layer 7 is provided on one side of the lower transverse plate away from the seismic isolation joint 3, and the upper transverse plate is overlapped on the upper end of the building surface layer 7. One end of the building surface layer 7 extends horizontally to the first supporting portion, and the other end of the building surface layer 7 extends to the connecting plate of the supporting member 8. The building surface layer 7 is constructed on the floor body 1, and is used to decorate the floor body 1 and support the upper transverse plate.

[0038] The seismic isolation structure also includes an auxiliary support member 9, which is located between the supporting member 8 and the seismic isolation joint 3; the auxiliary support member 9 is an L-shaped member, and the auxiliary support member 9 includes a horizontal section and a vertical section; the horizontal section is attached to the upper end surface of the floor body 1, and the vertical section extends upward along the boundary of the horizontal joint 6 to the lower end surface of the seismic isolation component 10.

[0039] The horizontal section of the auxiliary support member 9 is fixed to the upper end surface of the floor body 1 by means of bolts and other connectors. The auxiliary support member 9 is located on the side of the support member 8 close to the seismic isolation joint 3, and the vertical section of the auxiliary support member 9 extends longitudinally and abuts against the middle of the seismic isolation component 10.

[0040] Optionally, the vertical section is vertically connected to the horizontal section. The auxiliary support member 9 can be an angle steel, one right-angle side of the angle steel is fixed to the floor body 1 by bolts, and the edge of the other right-angle side is attached to the lower end of the seismic isolation component 10 .

[0041] The auxiliary support member 9 cooperates with the support member 8 to support the lower end of the seismic isolation component 10 to prevent the seismic isolation component 10 from being deformed or collapsed in the middle; and to increase the slipperiness of the seismic isolation component 10.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
