Description

Technical Field

[0001] This utility model relates to the field of deep foundation pit support technology, specifically to a fixing mechanism for steel support of deep foundation pits. Background Technology

[0002] In recent years, with the rapid development of my country's economy, a large number of high-rise buildings, super high-rise buildings and municipal engineering projects (roads, bridges, subways, etc.) have emerged in urban construction, and deep foundation pit projects are becoming more and more common. Deep foundation pit support technology has been widely used. Deep foundation pits refer to projects with an excavation depth of more than 5 meters (including 5 meters), or projects with a depth of less than 5 meters but particularly complex geological conditions, surrounding environment and underground pipelines. However, in the process of using deep foundation pits, steel support structures are needed to support them.

[0003] The existing technology has the following problems:

[0004] In existing technologies, fixing mechanisms are often fixed by welding or bolts, which makes the subsequent disassembly process cumbersome and laborious. In addition, existing deep foundation pit steel supports use left and right steel plates to block the inner wall of the deep foundation pit to prevent collapse. However, the bottom of the deep foundation pit is usually uneven. When the two steel plates are placed in the deep foundation pit at different heights, the left and right fixing structures cannot be in the same horizontal position, thus affecting the connection and fixation between the support column and the two steel plates.

[0005] Therefore, we need a fixing mechanism for steel supports in deep foundation pits to solve the above problems. Utility Model Content

[0006] This utility model provides a fixing mechanism for steel supports in deep foundation pits to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A fixing mechanism for steel supports in deep foundation pits includes two support columns and steel plates. Fixing components are fixedly connected to the upper surfaces of the two steel plates, with the left and right fixing components mirror images of each other. Anti-detachment rings are fixedly connected to the left and right ends of the front and rear support columns. Each of the left and right fixing components includes a fixing seat. A through groove is formed on the upper surface of the fixing seat, and U-shaped grooves are formed on the front and rear sides of the inner wall of the through groove. The interiors of the front and rear U-shaped grooves overlap with the outer surfaces of the support columns. A trapezoidal block is fixedly connected to the upper end of each of the two steel plates, and several water-guiding grooves are formed on the front and rear sides of the upper surface of the trapezoidal block.

[0009] A further improvement of this utility model is that the outer surface of the front and rear support columns extends into the interior of the through groove, and the outer surface of the anti-detachment ring in the front and rear support columns overlaps with the inner wall of the through groove.

[0010] A further improvement of this utility model is that: an installation groove is provided above the vertically opposite surfaces of the U-shaped groove, and a magnetic suction plate is movably connected inside the rear installation groove, with the outer surface of the magnetic suction plate overlapping the inside of the front installation groove.

[0011] A further improvement of this utility model is that the fixing base is made of metal, and the outer surface of the fixing base is magnetically fixed to the outer surface of the magnetic plate.

[0012] A further improvement of this utility model is that: U-shaped rods are fixedly connected to the front and rear of the steel plates on the left and right sides, and the outer surface of the U-shaped rods is slidably connected to the interior of the fixing component.

[0013] A further improvement of this utility model is that: a scale area is provided on the opposite front side of the steel plates on the left and right sides, a scale is engraved on the surface of the scale area, an indicator is overlapped on the surface of the scale area, and the lower surface of the indicator is fixedly connected to the surface of the fixing component.

[0014] A further improvement of this utility model is that: several threaded holes are provided on the front and back of the steel plates on the left and right sides; U-shaped support seats are fixedly connected to the front and back of the lower surface of the fixing components on the left and right sides; a support plate is movably connected inside the U-shaped support seat; a fixing block is fixedly connected to the lower end of the support plate; a fixing bolt is threadedly connected to the upper and lower surfaces of the fixing block; and the outer surface of the fixing bolt is threadedly connected to the inside of the threaded hole.

[0015] A further improvement of this utility model is that the support plate, fixing block, and fixing bolt in the steel plates on the left and right sides are arranged in a mirror image.

[0016] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0017] 1. This utility model provides a fixing mechanism for steel supports in deep foundation pits. It adopts the cooperation of fixing components, fixing seats, through grooves, U-shaped grooves, installation grooves, and magnetic suction plates. In use, the support column is placed inside the U-shaped groove by a crane, thereby achieving positional support for the steel plates on the left and right sides. At the same time, after the worker rotates the magnetic suction plate to the appropriate position, it blocks the support column. Through the design of this structure, the support column can be installed quickly, and it is also easy to disassemble later.

[0018] 2. This utility model provides a fixing mechanism for steel supports in deep foundation pits. It adopts the cooperation of U-shaped rods, scale areas, indicators, threaded holes, fixing blocks, fixing bolts, support plates, and U-shaped support seats. By placing two steel plates in the deep foundation pit, the fixing components on the left and right sides are moved to the appropriate positions, and the position of the indicator is observed to ensure that the fixing components on the left and right sides are at the same horizontal height. The adjusted positions are fixed by setting the fixing blocks, support plates, fixing bolts, and threaded holes. This structure allows the two steel plates to be adjusted to the same horizontal position in the uneven deep foundation pit, which facilitates the installation of the support column.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1: As Figures 1 to 4 As shown, this utility model provides a fixing mechanism for steel support of deep foundation pit, including two support columns 1 and two steel plates 2. Fixing components 3 are fixedly connected to the upper surface of the opposite side of the two steel plates 2. Trapezoidal blocks 4 are fixedly connected to the upper end of the two steel plates 2. Several water guide grooves 41 are opened on the front and back of the upper surface of the trapezoidal blocks 4. The water guide grooves 41 facilitate the drainage of rainwater.

[0026] The fixing component 3 includes a fixing base 31, which is made of metal. This material ensures that the fixing base 31 has sufficient strength and stability. The through groove 32 on the upper surface of the fixing base 31 is the main receiving space for the support column 1. The U-shaped grooves 33 on the front and rear sides of the inner wall of the through groove 32 are used to overlap with the outer surface of the support column 1. The outer surfaces of the front and rear support columns 1 extend into the through groove 32, and the outer surface of the anti-detachment ring 11 on the support column 1 overlaps with the inner wall of the through groove 32 to achieve initial positioning. The mounting groove 34 is opened on the upper side of the vertically opposite side of the U-shaped groove 33. A magnetic suction plate 35 is movably connected inside the rear mounting groove 34. The magnetic suction plate 35 can rotate flexibly in the mounting groove 34, and its outer surface overlaps with the inside of the front mounting groove 34. At the same time, the outer surface of the fixing base 31 and the outer surface of the magnetic suction plate 35 are fixedly connected by magnetic attraction. This magnetic attraction fixing method is convenient to operate and can quickly fix the support column 1 on the fixing base 31. It can also be easily removed when needed.

[0027] Example 2: Figures 1 to 4 As shown, U-shaped rods 21 are fixedly connected to the front and rear of the opposite sides of the left and right steel plates 2. The outer surface of the U-shaped rods 21 is slidably connected to the interior of the fixing component 3. The U-shaped rods 21 are used to adjust the overall structure of the fixing component 3 in the two steel plates 2 and to place the two fixing components 3 in the same horizontal position, which facilitates the subsequent installation of the support column 1. The front sides of the opposite sides of the left and right steel plates 2 are provided with scale areas 22. The surface of the scale areas 22 is engraved with scales, and the surface of the scale areas 22 is connected to indicators 23. Through this structure, workers can know the length of the fixing component 3 after it moves up and down, which facilitates the two fixing components 3 to move the same length. The lower surface of the indicator 23 is fixedly connected to the surface of the fixing component 3. Several threaded holes 24 are provided on the front and back of the opposite sides of plate 2. The threaded holes 24 are connected and fixed by fixing bolts 26. U-shaped support seats 28 are fixedly connected to the front and back of the lower surface of the left and right fixing components 3. A support plate 27 is movably connected inside the U-shaped support seat 28. A fixing block 25 is fixedly connected to the lower end of the support plate 27. Fixing bolts 26 are threaded through the upper and lower surfaces of the outer surface of the fixing block 25. The outer surface of the fixing bolt 26 is threaded to the inside of the threaded hole 24. The support plate 27, fixing block 25 and fixing bolt 26 in the left and right steel plates 2 are mirrored. This structure facilitates the installation and positioning of the left and right fixing components 3 after adjustment of their positions, and prevents the fixing components 3 from moving downwards.

[0028] Working principle: During installation, two steel plates 2 are first placed inside the deep foundation pit. The position of the fixing components 3 in the two steel plates 2 is pulled by the cooperation of the crane and the rope. The position of the indicator 23 is observed by the personnel. When the left and right fixing components 3 are at the same horizontal position, the position of the fixed components 3 is positioned by the setting of the fixing bolt 26 and the threaded hole 24. Then, the two support columns 1 are placed in the U-shaped groove 33 and the through groove 32 with the cooperation of the crane and the rope. Next, the magnetic suction plate 35 is rotated from the rear mounting groove 34 so that its outer surface contacts the inside of the front mounting groove 34, so that the magnetic suction plate 35 is magnetically fixed to the fixing seat 31, and the support column 1 is firmly fixed on the fixing seat 31.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
