Description

Technical Field

[0001] The utility model relates to a land pile foundation construction technology, in particular to a steel casing guide frame installation base. Background Art

[0002] When constructing bridge pile foundations, the bored pile construction method is adopted. After the drilling is completed at the construction site, the pile foundation steel casing needs to be buried in the hole. The verticality of the pile foundation steel casing must be strictly controlled to ensure that the verticality of the pile foundation penetrated inside it meets the requirements of the construction specifications.

[0003] The prior art usually uses the method of installing a guide frame to improve the verticality of the steel casing. The guide frame is fixed on the foundation, and the steel casing passes through the middle of the guide frame and is controlled by the guide frame. The horizontal position and verticality of the steel casing, in order to achieve a higher guide accuracy, the verticality of the guide frame itself also needs to be strictly controlled. The patent document with application number CN202322683857.5 discloses a double-layer limited guide frame leveling installation device for land steel casing installation, which includes a mounting stone, a leveling base and a level. The mounting stone is relatively horizontally arranged front and back, and a guide frame is installed between the two mounting stones through the leveling I-beams arranged on the left and right. The part of each leveling I-beam extending out of the guide frame is adjusted and installed through the leveling base and the mounting stone, and a level is installed on the guide frame. The above technical solution controls the verticality of the guide frame by leveling the base and the level, thereby ensuring the verticality of the steel casing, which can meet the general pile foundation construction needs. However, a large number of screws are required for the assembly of various components during the construction process, and when dealing with guide frames of different sizes, a large number of screws need to be disassembled and reinstalled, resulting in low construction efficiency. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a steel casing guide frame installation base, which is conducive to the rapid installation and leveling of the guide frame, can improve the construction efficiency and ensure the construction quality.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The camshaft is an angular channel structure formed between a pair of camshafts and a plurality of camshafts, the plurality of camshafts are connected to each other with a plurality of camshafts, the plurality of camshafts are connected to each other with a plurality of camshafts.

[0007] The utility model provides a base for fixing and installing a guide frame during pile foundation construction. During construction, two strip bases of the base are first fixed in parallel on the foundation, and then two adjusting pieces are set on each strip base, and the spacing between the two adjusting pieces on the same strip base is adjusted to the target value, and the positions of the adjusting pieces on the two strip bases are made to correspond one to one, and then the strip support seat is installed across the two strip bases, and the strip support seat is fixedly connected to the upper end of the adjusting piece, and the setting of the base is completed. The two strip bases and the two strip support seats form a square frame in the middle for the steel casing to pass through, and the upper side of the strip support seat can support the fixed guide frame. The utility model can change the size of the square frame by controlling the spacing between the two strip bases and the spacing between the two adjusting pieces on the same strip base, and is suitable for the construction of steel casings of different sizes, and the adjusting piece can arbitrarily change its position on the guide rail through the lower connecting part with a locking mechanism, without repeatedly disassembling and assembling screws, and is more convenient to use.

[0008] Furthermore, the linear guide rail protrudes relative to the middle of the strip bottom plate, the lower connecting portion forms a card frame, and the card frame includes two limit card plates arranged in parallel, and a card slot that can accommodate the linear guide rail is formed between the two limit card plates.

[0009] Furthermore, the locking mechanism includes a threaded sleeve connected to the outer side surface of the limiting clamping plate and a threaded rotating rod cooperating with the threaded sleeve.

[0010] Furthermore, the sides of the two strip-shaped bases are connected by a connecting rod.

[0011] Furthermore, the connecting rod comprises an outer sleeve rod and an inner sleeve rod which are slidably sleeved, and the outer sleeve rod is provided with a locking piece which can abut against the inner sleeve rod.

[0012] Furthermore, the connecting rod includes two outer rods near the two ends and an inner rod in the middle, the outer rod is fixedly connected to the side of the strip base, and a folding hinge is arranged in the middle of the inner rod.

[0013] Furthermore, the strip-shaped support seat includes a lower plate body and an upper plate body which are arranged in parallel, and the middle parts of the lower plate body and the upper plate body are connected by a supporting plate body.

[0014] Furthermore, a level is provided in the middle of the strip-shaped support seat.

[0015] In the prior art, the guide frame is usually fixed and installed, and then the verticality of the guide frame is adjusted using a level installed on the guide frame and a leveling mechanism arranged at the bottom of the guide frame. The disadvantage of this method is that the dead weight of the guide frame will make the leveling process more difficult. When the verticality deviation is large, the leveling process will take a long time. However, the utility model can pre-level the strip support seat before installing the guide frame, and then install the guide frame after the pre-leveling is completed. Since one of the directions of the guide frame has been pre-leveled, the time required for the overall leveling of the guide frame is reduced to a certain extent, which is conducive to improving construction efficiency.

[0016] Furthermore, the lower plate body is provided with strip-shaped mounting holes on both sides of the supporting plate body.

[0017] Furthermore, the height adjustment part is composed of a cylinder.

[0018] In summary, the application of the utility model can achieve the following beneficial effects:

[0019] 1. The utility model can change the size of the square frame by controlling the distance between two strip bases and the distance between two adjusting pieces on the same strip base, and is suitable for the construction of steel casings of different sizes.

[0020] 2. The adjusting member of the utility model can change its position on the guide rail at will through the lower connecting part with a locking mechanism, which reduces the repeated disassembly and assembly of the disassembly screws and is more convenient to use.

[0021] 3. In some embodiments of the present invention, a level is provided in the middle of the strip support seat, and the strip support seat can be pre-leveled before installing the guide frame. After the pre-leveling is completed, the guide frame can be installed. Since one position of the guide frame has been pre-leveled, the time required for the overall leveling of the guide frame is reduced to a certain extent, which is conducive to improving construction efficiency.
