Description

Technical Field

[0001] The utility model relates to the technical field of building construction structures, in particular to a combined steel column device used in foundation pit support in a reclamation area. Background Art

[0002] When supporting foundation pits in reclamation areas, the geological conditions are complex and changeable, especially the possible existence of soft soil layers and uneven settlement in reclamation areas, which brings great challenges to foundation pit support. Traditional foundation pit support methods, such as single type of support piles or steel sheet piles, are often difficult to meet the special requirements of foundation pit support in reclamation areas.

[0003] After consulting the relevant patent document CN216586566U, it is found that there are still some problems with the existing combined steel column device used in foundation pit support in reclamation areas. The optimization solutions currently on the market are mainly: the steel column module is welded from multiple steel columns, and the steel column has several connection areas, which has the advantages of high support strength, high construction efficiency, and saving manpower and material resources. The connection angle steel, the first connection ring and the second connection ring on the connection area can greatly improve the connection strength between the column and the horizontal support. However, this type of steel column device uses a welding connection method, which makes it impossible to disassemble and recycle it later, and its flexibility of use is not strong. In addition, the interior of the steel column is only cast with cement, which consumes a large amount of cement. In the later stage, due to the large amount of cement inside the column, it is difficult to recycle the column, resulting in a waste of resources. In response to the above problems, vertical plates, buckle plates, and engaging grooves are provided, so that multiple connecting columns can be butted together to complete assembly, thereby improving the flexibility of use. By providing a self-locking mechanism, the connecting columns can be locked with each other after the connection is completed to avoid falling off, avoiding the traditional bolt fixing method, and effectively reducing the installation time. By providing a casting mechanism, the strength between the cement and the column is increased, and it is convenient to pour out the cement molding later, thereby facilitating the recycling of the column.

[0008] As a further improvement of the above solution, the vertical plate is slidably connected to the inner wall of the meshing groove, the clamping plate is slidably connected to the inside of the meshing groove, and the clamping plate is in contact connection with the surface of the upper base.

[0009] As a further improvement of the above solution, the self-locking mechanism includes a positioning shaft, a torsion spring is sleeved on the surface of the positioning shaft, the bottom of the torsion spring is fixedly connected to the surface of the upper base, and a hollow sleeve is sleeved outside the torsion spring.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. For the combined steel column device used in the foundation pit support of the reclamation area, by setting up the vertical plate, the buckle plate, and the meshing groove, multiple connecting columns can be butt-jointed and assembled, improving the flexibility of use. By setting up the self-locking mechanism, after the connecting columns are butt-jointed, they can be locked with each other to avoid falling off, avoiding the traditional bolt fixing method, and effectively reducing the installation time. By setting up the pouring mechanism, while increasing the strength between the cement and the column, it is convenient to pour out the cement formed object later, thus facilitating the recycling of the column.

[0014] 2. For the combined steel column device used in the foundation pit support of the reclamation area, when connecting the upper connecting column and the lower connecting column, align the vertical plate and the buckle plate with the inside of the meshing groove, then push the lower connecting column upward until the buckle plate completely enters the inside of the meshing groove, and then rotate the lower connecting column so that the buckle plate can be buckled on the surface of the upper base to complete the butt-joint. The whole process is simple to operate, saving the butt-joint time; when rotating the lower connecting column, at this time the buckle plate will push the locking plate to rotate. When the buckle plate completely rotates to the narrow end of the meshing groove, at this time the locking plate loses the block and resets under the action of the torsion spring. At the same time, the limiting plate is limited by the blocking rod, so that the locking plate effectively limits the buckle plate inside the narrow end of the meshing groove. The installation and fixation are simple, saving the construction time. When pouring cement inside the pouring mechanism, at this time the cement contacts and solidifies with the support table, the column, and the connecting rod, so that the cement is combined with the inside of the whole pouring mechanism, thereby improving the strength of the pouring shell and not being easily deformed. When recycling the upper connecting column and the lower connecting column, just slide the pouring shell out of the inside of the upper connecting column. Multiple pouring mechanisms need to be slid into the inside of the upper connecting column and the lower connecting column, so that they form a whole inside the upper connecting column and the lower connecting column. The modular design improves the flexibility of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The drainage holes 2 are circumferentially and arrayed on the surface of the upper connecting column 1. The water retaining groove 3 is located at a certain distance directly above the upper base 4. The meshing grooves 5 are symmetrically distributed with the upper connecting column 1 as the axis.

[0026] The pouring mechanism 6 includes a pouring housing 601. The pouring housing 601 is slidably connected to the inner wall of the upper connecting column 1. Connecting plates 602 are fixedly connected to the inner wall of the pouring housing 601. The connecting plates 602 are symmetrically distributed with the support platform 603 as the axis. One end of the connecting plate 602 is fixedly connected to a support platform 603. Columns 604 are fixedly connected to the surface of the support platform 603. The columns 604 are circumferentially distributed with the support platform 603 as the axis, and the number is four groups. One side of the top of the column 604 is fixedly connected to a connecting rod 605. The support platform 603 is placed in the central area in the vertical direction inside the pouring housing 601.

[0027] The vertical plate 9 is slidably connected to the inner wall of the meshing groove 5, the buckle plate 10 is slidably connected to the inside of the meshing groove 5, and the buckle plate 10 is in contact connection with the surface of the upper end base 4.

[0028] The self-locking mechanism 11 includes a positioning shaft 111. A torsion spring 112 is sleeved on the surface of the positioning shaft 111. The bottom of the torsion spring 112 is fixedly connected to the surface of the upper end base 4. A hollow sleeve 113 is sleeved outside the torsion spring 112.

When recycling the upper connecting column 1 and the lower connecting column 7, only need to slide the pouring housing 601 out of the inside of the upper connecting column 1. Multiple pouring mechanisms 6 need to be slidably placed inside the upper connecting column 1 and the lower connecting column 7 so that they form a whole inside the upper connecting column 1 and the lower connecting column 7. The modular design improves the use flexibility.
