Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a temporary fixing device for the installation of embedded parts of seismic isolation bearings. Background Technology

[0002] In building construction, the superstructure and foundation are connected by seismic isolation bearings. These bearings mitigate earthquake damage, but the positioning accuracy of the embedded parts is extremely high, particularly in terms of horizontal position and elevation. According to the "Code for Construction and Acceptance of Seismic Isolation Engineering" (JGJ 360-2015), the allowable deviation in the installation position of seismic isolation bearings is very small, especially the horizontal deviation, which must not exceed 3‰. This necessitates the use of precise measuring instruments and tools during construction to ensure accurate installation of the embedded parts. Currently, during concrete pouring, the embedded parts are supported by fixing devices installed within the formwork cavity of the seismic isolation bearing pier. However, the flow of concrete during pouring can disturb these fixing devices, thus disturbing the embedded parts and resulting in poor fixation. Furthermore, traditional fixing devices eventually anchor themselves within the seismic isolation bearing pier, making them unrecyclable. Therefore, we propose a temporary fixing device for installing embedded parts in seismic isolation bearings to address these issues. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a temporary fixing device for installing embedded parts of seismic isolation bearings, which solves the problems of poor fixing effect and inability to be recycled and reused by traditional fixing devices.

[0004] This utility model is achieved through the following solution: a temporary fixing device for installing embedded parts of seismic isolation bearings, including a hanging plate, a support member for erecting the hanging plate above the seismic isolation bearing pier to be poured, and a connector fixed to the bottom of the hanging plate directly opposite the designed position of the embedded part. The connector is detachably connected to the embedded part to constrain the embedded part to be kept at the designed position of the embedded part during the pouring of the seismic isolation bearing pier.

[0005] A further improvement of this utility model for a temporary fixing device for installing embedded parts of seismic isolation bearings is that the support includes multiple telescopic rods arranged on the outer periphery of the seismic isolation bearing pier. The multiple telescopic rods extend vertically and are embedded in the concrete foundation structure at the bottom and fixed at the bottom of the hanging plate at the top.

[0006] A further improvement of this utility model for a temporary fixing device for installing embedded parts of seismic isolation bearings is that each of the telescopic rods includes a double-ended nut, a lower support rod, and an upper support rod. The lower end of the lower support rod is embedded in the concrete foundation structure, and the upper end of the lower support rod is screwed to the lower end of the double-ended nut. The upper end of the upper support rod is fixedly connected to the bottom of the hanging plate, and the lower end of the upper support rod is screwed to the upper end of the double-ended nut. By turning the double-ended nut, the distance between the upper support rod and the lower support rod can be adjusted, thereby adjusting the length of the telescopic rod and locking it.

[0007] A further improvement of this utility model for a temporary fixing device for installing embedded parts of seismic isolation bearings is that the connecting member includes at least two fixing rods symmetrically arranged along the center of the embedded part, the upper end of each fixing rod being fixedly connected to the hanging plate, and the lower end of each fixing rod being detachably connected to the embedded part.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] Before installation, the position of the embedded part is determined by measuring instruments and tools. Then, the temporary fixing device of this application is fixed to the periphery of the seismic isolation bearing pier to be poured, so that the embedded part is in the designed position. Since the temporary fixing device of this application is fixed to the periphery of the seismic isolation bearing pier, there will be no disturbance from the concrete, and the fixing effect is good. After the embedded part is anchored to the seismic isolation bearing pier, the upper support rod and the lower support rod are separated by tightening the double-ended nut, and then the fixing rod is removed from the embedded part. This allows most of the structure of this application to be disassembled, which can be recycled and reused, reducing construction costs. Attached Figure Description

Detailed Implementation

[0017] To address the problems of poor fixing effect and inability to be recycled and reused in traditional fixing devices, this utility model provides a temporary fixing device for installing embedded parts of seismic isolation bearings. The following detailed description, in conjunction with the accompanying drawings, provides further explanation of this temporary fixing device for installing embedded parts of seismic isolation bearings.

[0018] See Figures 1-6 As shown, a temporary fixing device for installing embedded parts of seismic isolation bearings includes...

[0019] The suspended plate 2, the support for erecting the suspended plate 2 above the seismic isolation bearing pier 7 to be poured, and the connector fixed to the bottom of the suspended plate 2 at the design position of the embedded part 4. The connector is detachably connected to the embedded part 4 to constrain the embedded part 4 to be kept at the design position of the embedded part 4 during the pouring of the seismic isolation bearing pier 7.

[0020] Specifically, in this embodiment, refer to Figure 1 As shown, the hanging plate 2 is cross-shaped, and the four sides of the hanging plate 2 correspond to the four corners of the embedded part 4 respectively; the hanging plate 2 is horizontal, and the suspended embedded part 4 is set parallel to the hanging plate 2.

[0021] Furthermore, a pouring port 6 extends through the central area of ​​the embedded part 4 along the thickness direction, and multiple seismic isolation bearing embedded sleeves 5 are fixedly connected to the embedded part 4; concrete can be poured into the mold cavity formed by the template through the pouring port 6 to form the seismic isolation bearing support 7, and the lower part of the multiple seismic isolation bearing embedded sleeves 5 and the embedded part 4 are anchored to the seismic isolation bearing support 7; the seismic isolation bearing can be installed through the multiple seismic isolation bearing embedded sleeves 5.

[0022] Before construction, the position of the embedded part 4 is determined by measuring instruments and tools, and then the temporary fixing device of this application is fixed to the periphery of the seismic isolation bearing pier 7 to be poured, so that the embedded part 4 is in the designed position; since the temporary fixing device of this application is fixed to the periphery of the seismic isolation bearing pier 7, there will be no disturbance from the concrete, and the fixing effect is good.

[0023] The support components include multiple telescopic rods 1 arranged around the periphery of the seismic isolation bearing pier 7. The multiple telescopic rods 1 extend vertically and are pre-embedded in the concrete foundation structure 8 at the bottom and fixed to the bottom of the hanging plate 2 at the top.

[0024] See Figure 2 , 5 As shown in Figure 6, each telescopic rod 1 includes a double-headed nut 103, a lower support rod 102, and an upper support rod 101. The lower end of the lower support rod 102 is embedded in the concrete foundation structure 8, and the upper end of the lower support rod 102 is screwed to the lower end of the double-headed nut 103. The upper end of the upper support rod 101 is fixedly connected to the bottom of the hanging plate 2, and the lower end of the upper support rod 101 is screwed to the upper end of the double-headed nut 103. By turning the double-headed nut 103, the distance between the upper support rod 101 and the lower support rod 102 can be adjusted to adjust the length of the telescopic rod 1 and lock it.

[0025] Specifically, the lower end of the upper support rod 101 is provided with a third screw hole for the upper end of the double-ended nut 103 to be inserted and screwed in, and the upper end of the lower support rod 102 is provided with a fourth screw hole for the lower end of the double-ended nut 103 to be inserted and screwed in.

[0026] Furthermore, the bottom of the lower support rod 102 is fixedly connected to a foot block 104, which is embedded in the concrete foundation structure 8 to provide stability for the entire installation and adjustment device.

[0027] By turning the double-ended nut 103, the upper support rod 101 can be adjusted by the thread, thereby driving the hanging plate 2 to rise and fall, and thus adjusting the height of the embedded part 4 so that the embedded part 4 is in the designed position for easy fixing. Furthermore, by turning the double-ended nut 103 to disengage the upper support rod 101 from the lower support rod 102 and then removing the fixing rod 3 from the embedded part 4, most of the structure of this application can be disassembled, recycled, and reused, reducing construction costs.

[0028] Among them, see Figure 1-4 As shown, the connector includes four fixing rods 3 symmetrically arranged along the center of the embedded part 4. The upper end of each fixing rod 3 is fixedly connected to the hanging plate 2, and the lower end of each fixing rod 3 is detachably connected to the embedded part 4.

[0029] Each fixed rod 3 includes a first connecting rod 301, a second connecting rod 305, a first clamping plate 302, and a second clamping plate 306. The first end of the first connecting rod 301 is fixedly connected to the bottom of the hanging plate 2, and the second end of the first connecting rod 301 is fixedly connected to the first clamping plate 302. The first end of the second connecting rod 305 is fixedly connected to the bottom of the hanging plate 2, and the second end of the second connecting rod 305 is fixedly connected to the second clamping plate 306. The embedded part 4 includes an embedded part body, a first clamping member 303, and a second clamping member 307. The first end of the first clamping member 303 is fixed to the bottom of the embedded part 4, and the second end of the first clamping member 303 is bent upward and extends into the pouring opening 6. The first end of the second clamping member 307 is fixed to the bottom of the embedded part 4, and the second end of the second clamping member 307 is bent upward and located at the edge of the embedded part 4.

[0030] Each fixing rod 3 also includes a first fastener 304 for locking the first locking plate 302 to the first locking piece 303 and a second fastener 308 for locking the second locking plate 306 to the second locking piece 307.

[0031] Further, see Figure 1 As shown, the four fixed rods 3 are fixedly connected to the four sides of the cross-shaped hanging plate 2;

[0032] By setting up four fixing rods 3, the stability of the suspended plate 2 suspending the embedded part 4 through the connector can be improved.

[0033] Among them, see Figure 2 and 4 As shown, the first fastener 304 includes a first bolt, a first screw hole opened at the top of the second end of the first clamping member 303, and a first through-hole 3041 extending along the thickness direction of the first clamping plate 302. The first clamping plate 302 and the first clamping member 303 are locked by the first bolt passing through the first through-hole 3041 and being inserted into the first screw hole.

[0034] Further, see Figure 2 and 3 As shown, the second fastener 308 includes a second bolt, a second screw hole opened at the top of the second end of the second clamping member 307, and a second through-hole 3081 extending along the thickness direction of the second clamping plate 306. The second clamping plate 306 and the second clamping member 307 are locked by the second bolt passing through the second through-hole 3081 and being inserted into the second screw hole.

[0035] By adopting the above settings, it is convenient to connect and disassemble the embedded part 4 and the hanging plate 2. After the embedded part 4 is anchored to the seismic isolation support 7, the first bolt can be turned to disengage from the first screw hole and the second bolt can be turned to disengage from the second screw hole, thereby realizing the separation of the hanging plate 2 and the embedded part 4, which is beneficial to the recycling operation.
