Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a seismic isolation support fire protection structure and a structural column connection node structure. Background Art

[0002] Seismic isolation is a new type of earthquake-resistant building structure. It is achieved by setting up seismic isolation bearings on the top of a column on a certain floor of the building to reduce the earthquake effect transmitted upward, thereby reducing the earthquake response of the structure.

[0033] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0034] like Figures 1 to 3 As shown, the present application provides a seismic isolation support fire protection structure, comprising:

[0035] An upper connecting member 2 and a lower connecting member 6 are arranged in an upper and lower interval;

[0036] A seismic isolation support 3, which is disposed between the upper connecting member 2 and the lower connecting member 6 and is detachably connected to the upper connecting member 2 and the lower connecting member 6;

[0037] An annular flexible fire barrier strip 4 surrounds the outer periphery of the seismic isolation support 3 and is detachably connected to the upper connecting member 2 and the lower connecting member 6;

[0038] The annular fireproof plate 5 surrounds the outer periphery of the flexible fireproof belt 4 and is detachably connected to the upper connecting member 2 and the lower connecting member 6 .

[0039] Among them, the upper connecting member 2 and the lower connecting member 6 are arranged in parallel and spaced apart from each other. During installation, the upper connecting member 2 is used to connect to the upper structural column 1, and the lower connecting member 6 is used to connect to the lower structural column 7, so that the seismic isolation bearing 3 is installed between the upper structural column 1 and the lower structural column 7 to achieve seismic isolation. The setting of the flexible fire barrier strip 4 and the fireproof board 5 can improve the fire resistance limit of the seismic isolation bearing 3 and improve the fire resistance performance of the seismic isolation bearing 3.

[0040] Therefore, the seismic isolation bearing fire protection structure in the present application is easy to construct and has a simple structure. By arranging a flexible fire barrier strip 4 and a fire barrier board 5 on the outer periphery of the seismic isolation bearing 3, the two form a double-layer fire protection structure, which can effectively improve the fire resistance limit of the seismic isolation bearing 3 and effectively improve the fire resistance performance of the seismic isolation bearing 3; at the same time, the flexible fire barrier strip 4 and the fire barrier board 5 are both detachable structures, which can be easily disassembled and replaced; thereby effectively solving the disadvantage of insufficient fire resistance limit of the seismic isolation bearing 3 (especially the rubber seismic isolation bearing), and also solving the problem of rapid replacement after a fire.

[0041] In a preferred embodiment, referring to Figure 1 The fireproof plate 5 includes an annular upper fireproof plate 51 and an annular lower fireproof plate 52. The upper end of the upper fireproof plate 51 is used to connect with the upper connecting piece 2, and the lower end of the lower fireproof plate 52 is used to connect with the lower connecting piece 6; the lower end outer wall of the upper fireproof plate 51 is provided with an upper ring plate 511 protruding outward, and the upper end outer wall of the lower fireproof plate 52 is provided with a lower ring plate 521 protruding outward. The upper ring plate 511 and the lower ring plate 521 are arranged opposite to each other up and down and an annular horizontal seam is formed therebetween, and a fireproof material layer 53 is provided in the annular horizontal seam.

[0042] The functions of the annular horizontal seam here are, firstly, to fill fireproof materials to form an outer fireproof layer with the upper fireproof plate 51 and the lower fireproof plate 52; secondly, when an earthquake occurs, horizontal displacement will occur between the upper connecting member 2 and the lower connecting member 6 connected to the structural column (specifically, between the first upper connecting plate 21 and the first lower connecting plate 61 described below). The existence of the annular horizontal seam allows the upper fireproof plate 51 and the lower fireproof plate 52 to slide relatively horizontally, thereby preventing the entire fireproof plate 5 from being damaged by an earthquake.

[0043] Generally, the flexible fire barrier strip 4 is made of silicone cloth. Of course, the flexible fire barrier strip 4 may also be made of other materials as required. This embodiment is only an example.

[0044] Further, see Figure 1 , the upper connecting member 2 includes a first upper connecting plate 21, an upper connecting tube 22, and a second upper connecting plate 23 connected in sequence from top to bottom, and the lower connecting member 6 includes a first lower connecting plate 61, a lower connecting tube 62, and a second lower connecting plate 63 connected in sequence from bottom to top; the upper and lower ends of the seismic isolation bearing 3 are detachably connected to the second upper connecting plate 23 and the second lower connecting plate 63 through corresponding first fasteners 31; the upper and lower ends of the flexible fire-blocking strip 4 are detachably connected to the first upper connecting plate 21 and the first lower connecting plate 61 through corresponding second fasteners 41, and the upper and lower ends of the fireproof plate 5 are detachably connected to the first upper connecting plate 21 and the first lower connecting plate 61 through corresponding third fasteners 54. Specifically, the upper end of the upper fireproof plate 51 is connected to the first upper connecting plate 21 through corresponding third fasteners 54, and the lower end of the lower fireproof plate 52 is connected to the first lower connecting plate 61 through corresponding third fasteners 54.

The cross-sectional area of ​​the second upper connecting plate 23 is smaller than the cross-sectional area of ​​the first upper connecting plate 21, and the cross-sectional area of ​​the second lower connecting plate 63 is smaller than the cross-sectional area of ​​the first lower connecting plate 61.

The upper connecting tube 22 and the lower connecting tube 62 preferably adopt circular tubes, which have the same bending and shearing properties in all directions, can better resist the earthquake effects in all directions that may occur, and avoid the weak direction. Of course, the upper connecting tube 22 and the lower connecting tube 62 can also adopt square tubes or other shapes of tube bodies as needed.

[0047] The upper structural column 1 and the lower structural column 7 in a general structural column are both reinforced concrete columns.

In order to facilitate the connection between the flexible fire barrier strip 4 and the first upper connecting plate 21 and the first lower connecting plate 61, the upper end of the flexible fire barrier strip 4 is bent outward to form an upper flexible ring, and the lower end thereof is bent outward to form a lower flexible ring. The upper flexible ring is connected to the first upper connecting plate 21 through the corresponding second fastener 41, and the lower flexible ring is connected to the first lower connecting plate 61 through the corresponding second fastener 41. In order to facilitate the connection between the upper fireproof board 51 and the lower fireproof board 52 and the first upper connecting plate 21 and the first lower connecting plate 61 respectively, the upper end of the upper fireproof board 51 is bent outward to form an upper connecting ring, and the lower end of the lower fireproof board 52 is bent outward to form a lower connecting ring.
