Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of shock insulation support pier, specifically relates to a positioning structure for large diameter shock insulation support pier construction. BACKGROUND

[0002] The shock insulation support pier is a key component for improving the seismic performance of building structure, which realizes the flexible connection between the building and the ground by adding a shock insulation layer between the upper structure of the building and the foundation and installing a rubber shock insulation support pier, effectively absorbing and offsetting about 80% of the seismic energy. In the construction process of the shock insulation support pier, the shock insulation support pier positioning plate plays a crucial role, which mainly increases the stability and positioning accuracy of the shock insulation support pier, preventing displacement or sliding of the shock insulation support pier under extreme conditions such as earthquakes.

[0003] There is some research on the structure of the positioning plate for the shock insulation support pier in the prior art. Referring to the patent document with application number 202210801176.1, a rubber shock insulation support pier installation method and the structure of its positioning plate are disclosed. A pouring opening is provided in the center of the positioning plate, and anchor holes are symmetrically arranged on both sides of the line connecting the midpoint of the pouring opening and the four corners of the positioning plate. A plurality of exhaust holes are uniformly distributed around the pouring opening on the positioning plate. Specifically, the design of the pouring opening allows the concrete to be accurately poured into the predetermined position, avoiding errors during the pouring process. The setting of the anchor holes ensures the accurate installation and fixation of the lower anchor, avoiding conflicts between the lower anchor and the lower support pier reinforcement, vertical reinforcement, and lower steel column, improving construction efficiency and safety. The uniformly distributed exhaust holes promote gas emission during the concrete pouring process, ensuring the density of the concrete and further improving the overall performance of the shock insulation support pier.

However, in actual application, especially for the construction of large-diameter isolation support piers, the pouring hole size reserved on the existing positioning plate is often small, which is difficult to meet the construction requirements of large-diameter support piers. In order to meet the construction requirements, the construction personnel usually need to expand the size of the pouring hole through additional cutting operation, which reduces the overall structural strength of the positioning plate, and further affects the pouring quality of the concrete, thereby affecting the stability and safety of the isolation support pier. The large-diameter isolation support pier refers to the isolation support pier with a diameter ranging from 1m to 1.6m.

[0026] Embodiment 1

[0027] Reference Figure 1 A positioning structure for large-diameter isolation support pier construction, comprising: a support framework and a support plate 1. The support framework divides the positioning structure into an intermediate pouring area and a plurality of positioning areas arranged around the intermediate pouring area, the support plate 1 is located in the positioning area and connected with the support framework; the intermediate pouring area is provided with a pouring opening; the lower part of the support framework is provided with an isolation support pier formwork connected with the support framework through the support plate 1; the isolation support pier formwork forms a pouring cavity, and the pouring opening is communicated with the pouring cavity; the ratio of the radial cross-sectional area of the pouring opening to the radial cross-sectional area of the positioning structure is (0.6-0.8):1 to meet the pouring requirements of large-diameter isolation support piers. In this embodiment, the ratio of the radial cross-sectional area of the pouring opening to the radial cross-sectional area of the positioning structure is 0.6:1, at this time, the radial cross-sectional area of the pouring opening is about 0.57m 2 , and the radial cross-sectional area of the positioning structure is about 0.95m 2 . At this time, the diameter of the isolation support pier is 1.1m.

[0028] Specifically, the support plate 1 can be a steel plate, a profile steel, a composite material plate, etc. The support plate 1 can enhance the overall rigidity and stability of the positioning structure. In this embodiment, the support plate 1 is a steel plate with a thickness of 3 mm, which is high in strength and easy to process and install.

[0029] Specifically, a plurality of reserved positioning holes 3 are formed in the support plate 1, and the number of the reserved positioning holes 3 matches the number of the connecting pieces on the seismic support pier, so as to ensure that the connecting pieces on the seismic support pier formwork accurately and stably pass through the reserved positioning holes 3 and are connected with the support framework.

[0030] Further, the radial cross-sectional shape of the pouring opening 2 can be a square or a polygon. According to the size and shape of the seismic support pier, the radial cross-sectional shape of the pouring opening 2 is selected, so as to facilitate the concrete to enter the pouring cavity from the pouring opening 2. Preferably, the radial cross-sectional shape of the pouring opening 2 is a polygon, which is convenient to adapt to different shapes of the seismic support pier and improve the accuracy and stability of positioning.

[0031] In this embodiment, the support framework forms the pouring opening 2 in the middle pouring area of the positioning structure. Due to the guiding and supporting effect of the support framework, the concrete uniformly fills the entire pouring opening 2 during pouring, and the generation of air bubbles and voids is reduced. Therefore, the concrete can achieve good flatness and compactness after pouring, without the need for additional troweling operation, thereby avoiding secondary troweling and improving construction efficiency and quality.

[0032] Referring to Figure 1 , the support framework comprises a surrounding piece 4 and a plurality of partition pieces 5. The plurality of partition pieces 5 surround the middle pouring area, and the surrounding piece 4 surrounds the plurality of partition pieces 5. Each partition piece 5 is connected with the surrounding piece 4, and the support plate 1 is connected with the partition pieces 5 and the surrounding piece 4.

The triangular structure has good mechanical properties and can withstand large loads and deformation.

[0034] More specifically, the partition piece 5 can be an angle steel, a channel steel, an I-beam, etc. The partition piece 5 can reinforce and stabilize the support framework. In this embodiment, the partition piece 5 is an angle steel L40, which can better adapt to loads of different angles and directions and improve the overall stability of the positioning structure.

[0035] More specifically, the enclosure 4 can be a ring-shaped steel plate, a hoop enclosed by angle steels, or a frame enclosed by section steels. The enclosure 4 can realize the closure and fixation of the pouring opening 2, and prevent the concrete from leaking or deforming during the pouring process. In the embodiment, the enclosure 4 is a hoop enclosed by angle steels L40.

[0036] In the embodiment, the hoop and the angle brace are both made of angle steels L40. During the pouring of the concrete, the angle steels L40 are permanently left on the top of the lower pier column and are not removed, which avoids the trouble of secondary removal. Meanwhile, the angle steels L40 have a small amount of copper, appropriate rigidity, and greatly reduced waste. The existing positioning structure is usually a consumable product, and therefore the setting of the angle steels L40 is more economical and practical.

[0037] In the embodiment, the plate members are connected by fillet welds, and the weld leg size is 3 mm.

[0038] Embodiment 2

[0039] The positioning structure for the construction of the large-diameter seismic pier in the embodiment 2 is provided with a plurality of reinforced steel plate strips 6 in the pouring opening 2 on the basis of the embodiment 1. The reinforced steel plate strips 6 provide additional support and ensure the stability of the seismic pier during the pouring process and assist in controlling the position and shape of the seismic pier. The reinforced steel plate strips 6 are connected with the partition members 5, and further enhance the stability and load-bearing capacity of the pouring opening 2.

[0040] Specifically, the reinforced steel plate strips 6 are provided in plurality, and the plurality of reinforced steel plate strips 6 form an enclosure. Each of the reinforced steel plate strips 6 is connected with the partition members 5. The enclosure is convenient for restraining the concrete and preventing the concrete from deforming or shifting during the pouring process. In the embodiment, the width of the reinforced steel plate strip 6 is 50 mm.

[0041] The radial cross-sectional shape of the enclosure can be circular, rectangular, polygonal, or the like. According to the size and shape of the seismic pier and the requirements for pouring the concrete, a suitable radial cross-sectional shape of the enclosure can be selected. Preferably, the radial cross-sectional shape of the enclosure is rectangular. The rectangular structure is convenient for adapting to the shape and size of the pouring opening 2, and improves the pouring quality and the stability of the seismic pier.

[0042] The working principle of the positioning structure for the construction of the large-diameter seismic pier is as follows. First, the positioning structure is placed on the seismic pier formwork, so that the connecting members on the seismic pier formwork pass through the reserved positioning holes 3, and the connecting members are accurately positioned. Then, the concrete is poured into the pouring cavity through the pouring opening 2. During the pouring of the concrete, the reinforced steel plate strips 6 and the support framework are used to restrain and fix the concrete. After the concrete solidifies, a stable and reliable seismic pier structure is formed.

[0043] The utility model discloses a preferred embodiment, not as such limit the protection scope of the utility model, therefore: all equivalent changes that do the structure, shape, principle of the utility model, should be covered in the protection scope of the utility model.
