Description

Technical Field

[0001] This utility model relates to a reusable column fixing support device. Background Technology

[0002] When reinforced concrete columns are subjected to low-cycle cyclic loading, a large base needs to be cast for each specimen to simulate the fixed end constraint at the column base in order to simulate the fixed support. Figure 1 To ensure the base remains intact and possesses sufficient rigidity and load-bearing capacity to maintain an elastic state during loading, it often requires a large amount of reinforcing steel, structural steel, and concrete, resulting in more than half of the specimen's cost being spent on the base. This method not only leads to high testing costs but also results in the support being disposable, causing significant resource waste. Utility Model Content

[0003] The purpose of this invention is to provide a reusable column fixing support device, which is convenient for use in quasi-static load tests of structures in civil engineering and can be reused.

[0004] The technical solution of this utility model is as follows: a reusable column fixing support device, including a steel outer frame with an inner circle projection of rectangle, each of the four inner sides of the steel outer frame is provided with a vertical side plate, and each of the four sides of the steel outer frame is provided with a plurality of threaded holes and bolts for pushing and fixing the vertical side plates are screwed in. Each of the four corners of the steel outer frame is provided with a sleeve that is integrated with the steel outer frame, and the sleeve is used for the anchor rod to pass through vertically and connect to the foundation.

[0005] Furthermore, the sleeve protrudes outward and is integrally formed with the steel outer frame.

[0006] Furthermore, the width of the vertical side plate is less than the width of the inner side of the cylindrical steel outer frame, and the height of the vertical side plate is less than or equal to the height of the steel outer frame.

[0007] Furthermore, the vertical side plate is made of steel plate.

[0008] Furthermore, the thickness of the vertical side plate is 5~10mm.

[0009] Furthermore, it is equipped with vertical side panels of various widths.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] This device is convenient for use in quasi-static load tests of structures in civil engineering. By adjusting the positions of the side plates and bolts, it can accommodate specimens of different sizes. The specimen is separated from the support using an assembly method, and then fixed in place by applying sufficient preload with bolts. Anchor rods are used to connect to the foundation, facilitating disassembly and relocation. The fixed support is reusable, solving the problems of high cost, resource waste, and non-reusability of existing cast-in-place supports, effectively reducing testing costs and avoiding resource waste.

[0015] To make the above-mentioned features and advantages of this utility model more easily understood, specific embodiments are described below in conjunction with the accompanying drawings, but this utility model is not limited thereto.

[0016] refer to Figure 2

[0017] A reusable column fixing support device includes a steel outer frame 10 with an inner ring projection of rectangle. Each of the four inner sides of the steel outer frame is provided with a vertical side plate 20. Each of the four sides of the steel outer frame is provided with a plurality of threaded holes 11 arranged in a matrix. Bolts 30 for pushing and fixing the vertical side plates are screwed into the threaded holes. At each of the four corners of the steel outer frame, a sleeve 12 is vertically provided and integrated with the steel outer frame. The sleeve has a vertically provided anchor hole 13. An anchor rods connected to the foundation pass vertically through the anchor holes on the sleeve to play a fixing role.

[0018] In this embodiment, the sleeve is columnar and vertically arranged, protruding outward and integrally formed with the steel outer frame.

[0019] In this embodiment, the width of the vertical side plate is smaller than the width of the inner side of the steel outer frame, so that there is no interference between them when the bolts push the vertical side plates. Multiple vertical side plates of different widths are also provided to allow for the use of different sizes of vertical side plates according to the specifications of the column. When selecting vertical side plates, those with a width smaller than the width of the specimen are typically chosen.

[0020] In this embodiment, the height of the vertical side panel is less than or equal to the height of the steel outer frame, which helps to conceal the vertical side panel within the steel outer frame. In another embodiment, to facilitate the placement of the vertical side panel, its height can be slightly higher than the height of the steel outer frame.

[0021] In this embodiment, the vertical side plate is a steel plate, and the thickness of the vertical side plate is 5~10mm.

[0022] In use, place the vertical side plates inside the outer frame, position the specimen in the middle of the four vertical side plates, and move the vertical side plates by rotating the bolts to fix their position. Then apply sufficient preload to the bolts to ensure the specimen does not move. A verticality measuring instrument can be used to ensure the specimen's verticality. Anchor rods anchored to the ground are passed through anchor holes and tightened with nuts to anchor the steel support to the ground. The specific installation structure is as follows... Figure 1 As shown.

[0023] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, a fixed connection can be understood as: a fixed connection that can be detached (e.g., using bolts or screws), or a fixed connection that cannot be detached (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured by integral molding using casting process) (except where it is obviously impossible to use an integral molding process).

[0024] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.

[0025] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.

[0026] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
