Description

Technical Field

[0001] This utility model belongs to the field of civil engineering foundation pit support construction technology, and in particular relates to a positioning control frame suitable for H-beams. Background Technology

[0002] In the construction of SMW (cement-soil mixing wall) piles, precise positioning of H-beams and triaxial cement-soil mixing piles is crucial to ensuring the strength, impermeability, and steel recycling rate of the deep foundation pit support structure. Traditional positioning control frames often use fixed channel steel guide rails or simple adjustable frames, which have the following significant drawbacks:

[0003] Insufficient verticality control: Verticality deviation often exceeds 3‰, resulting in excessive gap between the waler and the steel section, cracking and leakage of cement and soil, and easy damage to the pile body when the steel section is pulled out due to tilt.

[0004] Poor adaptability to complex working conditions: When constructing interlocking piles, inclined piles, and dense pile groups, traditional devices cannot simultaneously adjust the pile hole spacing and steel angle, requiring repeated disassembly and reassembly, resulting in accumulated measurement errors and extending the construction period by more than 20%.

[0005] Low construction efficiency and waste of resources: The full-span support frame, combined with manual positioning, consumes a large amount of steel and manpower. The material reuse rate is less than 50%. Frequent high-altitude operations pose significant safety hazards.

[0006] Therefore, there is an urgent need for a new type of positioning control frame that can effectively improve the reusability, reduce the number of calibrations, and save time and materials. Utility Model Content

[0007] The purpose of this utility model is to provide a positioning control frame suitable for H-beams, which can solve the problems of large construction deviation and low efficiency of traditional fixed guide frames in scenarios such as interlocking piles and inclined piles.

[0008] This utility model is implemented as follows: a positioning control frame suitable for H-beams includes longitudinal beams, two longitudinal beams are arranged in parallel and spaced apart, and a crossbeam is fixed to each end of the beam. The two longitudinal beams and the two crossbeams at the ends together form a rectangular main frame.

[0009] At least two spaced crossbeams are fixed to the middle section of the two longitudinal beams, and the two adjacent crossbeams and the longitudinal beams on both sides together form a square-shaped positioning frame.

[0010] The length direction of the crossbeam is perpendicular to the length direction of the longitudinal beam.

[0011] In some implementations, the crossbeam and the longitudinal beam are connected by welding.

[0012] In some implementations, the surface of the longitudinal beam is provided with pile hole spacing scale lines, which correspond one-to-one with the insertion position of the H-beam, so as to realize the synchronous marking function of the pile holes.

[0013] In some implementations, the distance between two adjacent crossbeams is greater than the width of the H-beam by 20cm, thereby enabling horizontal displacement adjustment of the H-beam.

[0014] In some implementations, the crossbeam is integrally formed from Q355B grade 500×300 steel, and is compatible with H500×200 to H700×300 steel specifications.

[0015] Compared with the prior art, the advantages of this utility model are as follows:

[0016] The positioning control frame provided by this utility model connects the longitudinal beams and transverse beams to form an integrated positioning frame, which is convenient to construct, applicable to general SMW method pile construction, and reusable, effectively ensuring the recyclability of materials. It can reduce the sinking and positioning time of H-beams, improve construction efficiency, reduce construction costs, and shorten the construction period, resulting in significant social and economic benefits. It can quickly and accurately position the H-beams, improving the verticality of the SMW method and thus ensuring the quality of engineering construction. It is safe and reliable, enhancing the stability of the locator and ensuring the safety of construction personnel. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0022] Please see Figure 1 This embodiment shows a positioning control frame suitable for H-beams, including longitudinal beams 1 and transverse beams 2. The two longitudinal beams 1 are arranged in parallel and spaced apart. A transverse beam 2 is fixed at each end of the longitudinal beam 1. The two longitudinal beams 1 and the two fixed transverse beams 2 at the ends together form a rectangular main frame.

[0023] Two horizontal beams 2 are fixed in the middle section of the two longitudinal beams 1. The two adjacent horizontal beams 2 and the longitudinal beams 1 on both sides together form a square-shaped positioning frame.

[0024] In this embodiment, the length direction of the crossbeam 2 is perpendicular to the length direction of the longitudinal beam 1, and the crossbeam 2 and the longitudinal beam 1 are connected by welding.

[0025] Specifically, the longitudinal beams 1 on both sides are usually made of channel steel or I-beams. The distance between the two longitudinal beams 1, i.e. the width of the main frame, is the same as the diameter of the mixing pile. The length of the main frame is based on one pile and three pile holes, and is positioned at the top of the pile.

[0026] The surface of the longitudinal beam 1 is provided with pile hole spacing scale lines, which correspond one-to-one with the insertion position of the H-beam 3 to realize the synchronous marking function of the pile holes.

[0027] The crossbeam 2 is made of Q355B grade 500×300 steel in one piece, and is compatible with H500×200 to H700×300 steel specifications.

[0028] Please refer to the following: Figure 2 The distance between two adjacent crossbeams 2 is greater than the width of the H-beam by 20cm. That is, when the H-beam 3 is positioned, the distance from both ends to the positioning frame is reserved by 10cm to realize the horizontal displacement adjustment of the H-beam 3.

[0029] The H-beam 3 used in construction is a standard H-beam, which serves as the main structure for inserting into the pile hole. The flange width is 300mm and the web thickness is 13mm. The flange surface is sprayed with a wear-resistant coating to reduce insertion friction resistance.

[0030] In practical applications, the positioning control frame of this embodiment can be customized according to the size of the H-beam 3, and is also adapted to the construction requirements of inclined piles. By connecting with the crossbeam 2 to form a steel positioning frame, the verticality deviation can be controlled to ≤1.5‰.

[0031] The positioning control frame provided by this utility model connects the longitudinal beam 1 and the transverse beam 2 to form an integrated positioning frame. It is convenient to construct, applicable to general SMW method pile construction, and reusable, effectively ensuring the recyclability of materials. It can reduce the sinking and positioning time of H-beams, improve construction efficiency, reduce construction costs, and shorten the construction period, achieving the goals of "rapid positioning (installation ≤10 minutes), rapid construction (efficiency increased by 40%), and low-cost operation (overall cost reduced by 40%)" for H-beams. It can quickly and accurately position the H-beams, improving the verticality of the SMW method and thus ensuring the quality of engineering construction. It is safe and reliable, enhancing the stability of the locator and ensuring the safety of construction personnel. It provides a high-precision, high-efficiency, and low-cost support solution for challenging projects such as deep foundation pits in subways and underground pipe corridors, promoting the industrialization and standardization of SMW method pile technology, with significant social and economic benefits.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
