Description

Technical Field

[0001] The utility model belongs to the technical field of building isolation bearings, and particularly relates to a positioning plate for an anti-seismic bearing. Background Technique

[0002] An anti-seismic bearing refers to a support device set to meet the requirements of seismic isolation. An isolation layer is added between the superstructure and the foundation, and a rubber isolation bearing is installed to achieve a soft connection with the ground. It is a structural member with relatively small horizontal stiffness and relatively large vertical stiffness, and is applied to the structural reinforcement of various buildings and highway bridges to achieve the effects of earthquake resistance, seismic isolation, and shock absorption.

[0003] Among them, the isolation rubber bearing is a very effective isolation product with good bearing capacity and seismic resistance. At present, when installing the isolation rubber bearing, it needs to be connected to the ground foundation. Generally, steel plates are embedded in the foundation, and then the anchor bars are correspondingly connected to the sleeves on the embedded steel plates, and then concrete slurry is poured. After that, the isolation rubber bearing is connected to the embedded steel plate through connectors. However, in the actual construction process, the line of sight is blocked by the embedded steel plate, resulting in difficult construction. It is not easy to control the concrete grouting under the steel plate, and there are risks such as incomplete grouting and cavities.

[0004] For example, the Chinese utility model patent with the patent publication number CN220868495U and the publication date of April 30, 2024, discloses a vibration isolation bearing for an anti-vibration platform. The structure includes: an upper embedded part and upper anchor bars are arranged above the upper positioning plate, sleeves are arranged at the lower ends of the upper anchor bars, and a connecting plate is arranged below the upper positioning plate; a lower positioning plate, a lower embedded part and lower anchor bars are arranged below the lower positioning plate, sleeves are arranged at the upper ends of the lower anchor bars, a connecting plate is arranged above the lower positioning plate, and a buffer partition and a vibration isolation bearing are arranged between the connecting plates.

[0005] The vibration isolation bearing for the anti-vibration platform in this utility model patent has the following general structural principle: connecting plates are arranged at both the upper and lower ends of the vibration isolation bearing. The connecting plates are screwed to the upper anchor bars, sleeves, upper embedded parts at the upper end and the lower embedded parts, lower anchor bars, sleeves at the lower end through the upper positioning plate and the lower positioning plate, so that the levelness of the vibration isolation bearing meets the requirements.

[0006] However, during the actual use of this vibration isolation bearing for the anti-vibration platform, there are at least the following two deficiencies, that is, the technical problems to be solved by this utility model.

[0007] 1. Its lower positioning plate is a plate-like structure, which is easy to block the line of sight, is not conducive to installing the lower anchor bars, and is also not conducive to observing the density of the slurry.

[0008] 2. Under the premise of ensuring sufficient support strength, the structure of its lower positioning plate has a relatively large self-weight, which ultimately affects the support strength and increases the material cost.

[0009] Therefore, in summary, there is an urgent need for a positioning plate for a new type of seismic isolation bearing that has no line of sight obstruction, low consumables, and a large thickness. Summary of the Invention

[0010] The present invention provides a positioning plate for a new type of seismic isolation bearing. By setting an outer frame unit and an internal reinforcement plate unit, the following effects can be achieved: 1. The outer frame unit and the internal reinforcement plate unit are connected to the lower connecting plate. The positioning plate for the seismic isolation bearing is provided with a hollow structure, which will not form a line of sight obstruction, facilitating the installation and fixation of the casing and the lower anchor bars. At the same time, the irrigation situation of the concrete slurry can be observed in real time and adjusted to ensure the density of the slurry; 2. The outer frame unit is a hollow square tube. Without increasing the weight and cost of the positioning plate, the connection strength and the thickness of the positioning plate are ensured, so that the outer frame unit will not deform or shift when connected to the seismic isolation bearing, ensuring the horizontal verticality and connection strength of the seismic isolation bearing.

[0011] The technical solution adopted by the present invention to solve the above problems is: a positioning plate for a seismic isolation bearing, the structure of which includes an outer frame unit for supporting the lower connecting plate and bolts, and an internal reinforcement plate unit arranged inside the outer frame unit and used for supporting the lower connecting plate.

[0012] A further preferred technical solution lies in that: the outer frame unit includes four side plates for supporting the lower connecting plate, and openings arranged on the side plates for installing the bolts.

[0013] A further preferred technical solution lies in that: the internal reinforcement plate unit includes a connecting plate with both ends arranged on two of the side plates and used for supporting the lower connecting plate.

[0014] A further preferred technical solution lies in that: the outer frame unit further includes engaging blocks and engaging grooves arranged at both ends of the side plates.

[0015] A further preferred technical solution lies in that: the connecting plate is replaced with a support plate, and auxiliary holes for installing the bolts are further arranged on the support plate.

[0016] A further preferred technical solution lies in that: the outer frame unit further includes support angle plates arranged on two adjacent side plates and used for installing the connecting plate.

[0017] A further preferred technical solution lies in that: the outer frame unit further includes connection holes arranged on the support angle plates, the internal reinforcement plate unit further includes installation holes arranged on the connecting plate, and connection bolts arranged on the installation holes and used for connecting the support angle plates.

[0018] A further preferred technical solution is that: the number of the connecting plates is 2.

[0019] A further preferred technical solution is that: the outer frame unit further includes a positioning ring which is arranged on the upper surface of the side plate and is used for inserting the bolt.

[0020] A further preferred technical solution is that: the outer frame unit further includes an L-shaped reinforcing plate arranged on the side ends of two adjacent side plates. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The following is only a preferred embodiment of the present utility model, and does not limit the scope of the present utility model.

[0034] As shown in the appendix Figures 1 - 7 As shown, a positioning plate for a seismic isolation bearing, the structure includes an outer frame unit 1 for supporting a lower connecting plate b and a bolt f, and an internal reinforcement plate unit 2 disposed within the outer frame unit 1 and for supporting the lower connecting plate b.

[0035] In this embodiment, before the seismic isolation bearing a is installed, sleeve embedding needs to be carried out first. Therefore, the positioning plate for the seismic isolation bearing is used to connect the seismic isolation bearing a, the lower connecting plate b, the sleeve d and the lower anchor bar e in sequence with the bolt f. As shown in the appendix Figure 1 As shown, after the positioning plate for the seismic isolation bearing determines the installation positions of the sleeve d and the lower anchor bar e, concrete slurry needs to be poured. After pouring, the seismic isolation bearing a is installed, as shown in the appendix Figure 7 As shown, after the seismic isolation bearing a is installed, the upper connecting plate c, the sleeve d and the upper anchor bar g are connected in sequence through the shown bolt f, and then concrete slurry is poured to complete the installation and setting of the seismic isolation bearing a.

[0036] In addition, the function of the outer frame unit 1 is to connect the seismic isolation bearing a with the sleeve d and the lower anchor bar e, and to ensure the horizontal verticality of the seismic isolation bearing a during installation, playing a role of supporting and positioning. Since the outer frame unit 1 is provided with a hollow structure, the outer frame unit 1 will not be blocked by the line of sight when connecting the sleeve d and the lower anchor bar e, and the installation is more convenient and fast. At the same time, the installation stability can be well inspected. In addition, when pouring concrete slurry, the compaction condition of the concrete slurry can be observed in real time, and no bubbles or cracks will be generated, ensuring the structural stability. Secondly, the outer frame unit 1 adopts a hollow structure. Under the same material and weight conditions, the thickness of the outer frame unit 1 is larger than that of the existing connecting plate, so that the connection stability of the outer frame unit 1 is better, not easily deformed, increasing the connection strength, having sufficient stiffness, avoiding the relative position deformation of the sleeve d, and ensuring the accurate positioning of the sleeve d.

[0037] Finally. The function of the internal reinforcement plate unit 2 of the outer frame unit is to further reinforce the outer frame unit 1, and at the same time can play a supporting effect on the seismic isolation bearing a and the lower connecting plate b, further ensuring the horizontal verticality and stability of the installation of the seismic isolation bearing a.

[0038] The outer frame unit 1 includes four side plates 101 for supporting the lower connecting plate b, and openings 102 disposed on the side plates 101 and for installing the bolt f.

[0039] In this embodiment, the four side plates 101 enclose a rectangular frame, and through the openings 102 provided on the side plates 101, the lower connecting plate b and the sleeve d are connected and fixed by using the bolt f, and the openings 102 are correspondingly arranged with the connecting holes on the lower connecting plate b.

[0040] The internal reinforcement plate unit 2 includes a connecting plate 201 with both ends provided on two of the side plates 101 and used for supporting the lower connecting plate b.

[0041] In this embodiment, the connecting plate 201 is used for supporting the lower connecting plate b.

[0042] The outer frame unit 1 further includes engaging blocks 103 and engaging grooves 104 provided at both ends of the side plates 101.

[0043] In this embodiment, the engaging blocks 103 and the engaging grooves 104 are provided at both ends of the side plates 101. The side plates 101 can be respectively provided with the engaging blocks 103 and the engaging grooves 104 at both ends, so as to be inserted end to end for installation and fixation; the side plates 101 can also use a single engaging block 103, and the adjacent side plates 101 are provided with the engaging grooves 104 engaged with the engaging block 103, so as to connect and fix the four side plates 101. The above settings make the installation and transportation of the outer frame unit 1 more convenient.

[0044] The connecting plate 201 is replaced with a support plate 202, and further includes auxiliary holes 203 provided on the support plate 202 and used for installing the bolt f.

[0045] In this embodiment, the support plate 202 is arranged at the four corners of the side plate 101 to support the seismic isolation bearing a. The support plate 202 can be trapezoidal, triangular, etc. Preferably, the support plate 202 is trapezoidal, so that there is a certain distance between the support plate 202 and the side plate of the side plate 101 to achieve hollowing, thereby reducing occlusion. The function of the auxiliary hole 203 is that on the one hand, when the specification of the seismic isolation bearing a is too small, without replacing the positioning plate for the seismic isolation bearing, the auxiliary hole 203 can be set on the support plate 202 to connect with the seismic isolation bearing a to adapt to the installation of the seismic isolation bearing a of different specifications. The support plate 202 can be detachably connected to the side plate 101, and by replacing the support plate 202 of different specifications, it can adapt to more specifications of the seismic isolation bearing a; on the other hand, the number of the lower anchor bars e is not fixed, and the lower anchor bars e can be further reinforced to ensure the installation stability of the seismic isolation bearing a. For example, the side plate 101 and the opening 102 are used to connect the seismic isolation bearing a with a specification of 800, and the support plate 202 and the auxiliary hole 203 can meet the installation of the seismic isolation bearing a with a specification of 700.

[0046] The outer frame unit 1 further includes a support angle plate 105 arranged on two adjacent side plates 101 and used for installing the connecting plate 201.

[0047] In this embodiment, the function of the support angle plate 105 is to install the connecting plate 201, so that the integrity of the positioning plate for the seismic isolation bearing is better and the structure is more firm.

[0048] The outer frame unit 1 further includes a connection hole 106 arranged on the support angle plate 105. The internal reinforcement plate unit 2 further includes an installation hole 204 arranged on the connecting plate 201, and a connection bolt 205 arranged on the installation hole 204 and used for connecting the support angle plate 105.

[0049] In this embodiment, the connection bolt 205 is inserted into the connection hole 106 and the installation hole 204, thereby connecting and fixing the support angle plate 105 and the connecting plate 201, which not only strengthens the structural strength, but also facilitates the installation, replacement and disassembly of the connecting plate 201.

[0050] The number of the connecting plates 201 is 2.

[0051] In this embodiment, there are 2 connecting plates 201. The connecting plates 201 can be set as an "X" - shaped or "cross" - shaped plate, or arranged horizontally.

[0052] The outer frame unit 1 further includes a positioning ring 107 arranged on the upper surface of the side plate 101 and used for inserting the bolt f.

[0053] In this embodiment, the positioning ring 107 can protect the side plate 101, reduce the loss caused by repeatedly screwing the bolt f, and at the same time facilitate the user to install the bolt f more quickly.

[0054] The outer frame unit 1 further includes L-shaped reinforcing plates 108 provided at the side ends of two adjacent side plates 101.

[0055] In this embodiment, the L-shaped reinforcing plate 108 is provided for reinforcing the corner connection of the side plate 101 to prevent the side plate 101 from cracking and deforming under stress.

[0056] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various modifications can be made without departing from the purpose of the present invention.
