Description

Technical Field

[0001] This invention relates to the field of building construction technology, and more specifically, to a positioning guide frame for vertical support lattice columns in deep foundation pits. Background Technology

[0002] With urban development and decreasing land available for construction, the development and utilization of underground space is showing a trend of large-scale expansion, leading to the frequent occurrence of ultra-large-scale deep foundation pits. Foundation pit engineering has become a crucial link in project construction, and its safety and stability have a significant impact on surrounding buildings and the environment. During the construction of lattice columns, it is necessary to effectively control indicators such as their top surface elevation, verticality, angular deviation from the axis of the supporting beam, and the depth of the inserted piles. Improper construction measures can cause significant deviations in the lattice columns, affecting the construction of the horizontal reinforced concrete support system and impacting the stress on the entire foundation pit support system. Therefore, during foundation pit construction, the quality control of the lattice columns, as a key vertical support system, becomes a priority.

[0003] The installation of existing lattice columns requires various auxiliary tools to ensure accuracy and stability. However, most existing installation tools are complex in structure, leading to inconvenience in operation and failing to meet the requirements for fast, efficient, and precise installation. Therefore, it is necessary to develop a lattice column guide frame that is simple in structure, easy to operate, and highly stable. Summary of the Invention

[0004] This invention provides a positioning guide frame for vertical support lattice columns in deep foundation pits, which can overcome some or all the defects of the prior art.

[0005] According to the present invention, a positioning guide frame for a vertical support lattice column in a deep foundation pit includes a guide frame body, the guide frame body including an operating platform for being disposed above the borehole, a suspension assembly for being disposed at the four corners of the outer wall of the lattice column, and a positioning assembly detachably disposed at the operating platform and extending into the lattice column. The positioning component is used to axially lock the inner wall of the lattice column, and the suspension component is detachably installed at the positioning component to position the axial elevation of the lattice column.

[0006] This invention has a simple structure, is easy to operate, and has high stability. It can meet the requirements of fast, efficient, and precise installation. Through the combined use of positioning components and operating platform, it can effectively ensure the installation accuracy and stability of lattice columns, facilitate the construction of subsequent support beams, reduce the occurrence of node enlargement heads, effectively control the stress balance of the system, and improve the overall stability of the foundation pit support system.

[0007] In addition, the present invention has the advantages of strong adaptability and good adjustability, and can be adjusted and adapted to lattice columns of different sizes, which greatly improves the installation accuracy.

[0008] Preferably, the operating platform includes four L-shaped bottom beams that together form a rectangle with adjustable side length. An adjustment plate is connected between the ends of adjacent bottom beams. A first adjustment slot is formed on the side wall of the adjustment plate. A first adjustment bolt is detachably provided at the ends of adjacent bottom beams, passing through the first adjustment slot. The first adjustment bolt is used to limit the movement between the adjustment plate and the bottom beam.

[0009] The above structure allows the operating platform to be quickly adjusted in size as needed to accommodate drilling and lattice column installation requirements of different sizes.

[0010] Understandably, the combined use of the adjusting plate and the first adjusting bolt allows construction workers to easily adjust the spacing between the bottom beams as needed, thereby ensuring that the operating platform can be stably supported above the borehole, providing a stable working platform for the installation of the lattice column.

[0011] Preferably, the bottom beams all have a corner section set at °, and the top wall of the bottom beams is provided with a support plate set along the diagonal of the corner section, with one end of the support plate extending into the borehole and the other end extending into the borehole.

[0012] The above structure not only enhances the overall rigidity of the bottom beam, making the operating platform more stable under stress, but also minimizes the space occupied by the support plate inside the operating platform, while maximizing the connection area between the support plate and the operating platform, thereby improving the installation and connection stability of the positioning components.

[0013] Preferably, the positioning component includes four positioning members corresponding to the four bottom beams. The positioning members are slidably disposed on the support plate. The four positioning members together form a rectangle with adjustable side length. A connecting component for adjusting the spacing is provided between adjacent positioning members. The connecting assembly includes a first connecting plate and a second connecting plate respectively disposed on the inner wall of adjacent angle steels. A third adjusting groove and a second adjusting groove are respectively formed on the side wall of the first connecting plate and the second connecting plate. A second adjusting bolt is detachably provided between the third adjusting groove and the second adjusting groove. The second adjusting bolt is used to guide and limit the first connecting plate and the second connecting plate.

[0014] By using the first connecting plate, the second connecting plate, and the second adjusting bolt in the connecting assembly, the spacing between adjacent positioning parts can be easily adjusted to accommodate lattice columns with different inner wall sizes.

[0015] Understandably, the side length of the rectangle formed by the positioning components can be adjusted by pulling the positioning components, making the adjustment simple and quick.

[0016] Preferably, the positioning element includes a vertically arranged angle steel that fits against the inner wall of the lattice column, and an adjustment element is formed on the outer wall of the angle steel along the diagonal of the corner, the adjustment element being used to adjust the position of the angle steel.

[0017] With the above structure, construction workers can quickly attach the angle steel to the inner wall of the lattice column using the adjusting parts. It can be quickly applied to lattice columns with different inner wall sizes, and the adjusting parts are used for positioning to ensure a stable locking of the lattice column.

[0018] Preferably, the adjusting component includes a sliding plate slidably disposed on the support plate, a groove is formed on the top wall of the sliding plate near the angle steel end, a first through-hole is formed on the bottom wall of the groove, a circular hole corresponding to the first through-hole is formed at the end of the support plate, and a positioning bolt passing through the first through-hole is detachably provided in the circular hole. A third opening is formed on both sides of the first opening at the bottom wall of the groove away from the angle steel. A threaded hole corresponding to the third opening is formed on the top wall of the support plate. A screw is detachably provided in the groove, which passes through the third opening and is threaded in the threaded hole. The screw and the positioning bolt are used together to guide and limit the sliding plate along the length of the support plate.

[0019] By passing the positioning bolt through the round hole and the first through-hole, the sliding plate can be fixed at any position on the support plate, achieving precise positioning of the angle steel.

[0020] Understandably, in addition to the guide limit provided by the positioning bolt, the screw passes through the third port and is threaded into the threaded hole, providing additional guide limit for the sliding plate. Through double limit, the stability of the adjusting component is enhanced, preventing the sliding plate from moving or deforming during the stress process, thereby ensuring the precise fit between the angle steel and the inner wall of the lattice column.

[0021] Meanwhile, the use of positioning bolts and screws for connection facilitates the disassembly and installation of the positioning components, and makes it easy to replace damaged positioning bolts and screws at a low cost.

[0022] Preferably, an extension column is formed at the top wall of the support plate corresponding to the first opening, penetrating the first opening. A hanger for cooperating with the suspension assembly is detachably provided above the sliding plate. The suspension assembly includes a hanger and a suspension member provided on the outer wall of the lattice column. An insertion port perpendicular to the support plate is formed inside the hanger. The suspension member has a first insert rod inserted into the insertion port and a second insert rod provided at the hanger. Both ends of the second insert rod and the first insert rod are provided with suspension rods for connection.

[0023] The extended columns on the support plate not only enhance the structural strength of the support plate and the adjusting component, but also provide a reliable mounting point for the hanger and provide additional guidance for the adjusting component to slide on the support plate.

[0024] Understandably, the extension column passes through the first opening, allowing the hanger to be stably fixed above the sliding plate, thereby cooperating with the suspension components to achieve effective support for the lattice column.

[0025] By setting up the suspension components, the insertion port formed inside the suspension member is set perpendicular to the support plate, which facilitates the insertion of the first insertion rod. At the same time, the second insertion rod is connected to the hanger, so that the suspension member can form a stable connection with the hanger. The first and second insertion rods are connected by the suspension rod, which realizes the efficient suspension and installation of the lattice column, thereby facilitating the adjustment of the lattice column elevation.

[0026] By rationally arranging the number and position of the suspension rods, it is possible to ensure that the lattice column maintains a stable posture during installation, preventing deformation or tilting caused by uneven stress.

[0027] Preferably, a locking component is detachably provided at the support plate, the locking component is used to form a one-way limit on the sliding plate, and a second opening is formed at the bottom wall of the groove on both sides of the first opening; The locking assembly includes a housing located above the sliding plate, and a fixing foot detachably located on the top wall of the support plate through a second through-hole formed on the bottom wall of the housing.

[0028] By setting the locking component, the movement of the sliding plate on the support plate is restricted in one direction, which ensures that the sliding plate can be pulled outward, thereby preventing the sliding plate from being pulled back and causing the angle steel to detach from the locking of the inner wall of the lattice column, thus affecting the installation accuracy.

[0029] Understandably, the locking assembly includes a housing located above the sliding plate, and a fixing foot formed by the bottom wall of the housing can pass through the second opening and be detachably located on the top wall of the support plate. This not only makes the installation and removal of the locking assembly very convenient, but also provides additional guidance and limiting functions for the sliding plate.

[0030] Preferably, a first toothed section is formed at the bottom wall of the groove, which is located between the second opening and the first opening, and a second toothed section is located between the third opening, and the first toothed section and the second toothed section are continuously arranged. An installation cavity is formed inside the housing. A ratchet is rotatably provided in the installation cavity to cooperate with the first and second toothed sections. The ratchet is used to limit the sliding plate in the drilling direction in one direction. A spring is provided between the top wall of the ratchet and the inner wall of the installation cavity. The spring is used to provide elastic force to keep the ratchet pressed down. A push rod for rotating the ratchet is provided at the top wall of the ratchet. A sliding groove for rotating the push rod is formed at the top wall of the housing.

[0031] The ratchet is designed to engage with the first and second toothed sections to create a one-way limit on the sliding plate in the drilling direction. In addition, the spring ensures that the ratchet is always engaged with the first and second toothed sections, allowing the angle steel to be locked after the sliding plate is pulled. The operation is simple and quick.

[0032] Understandably, after construction is completed, the ratchet can be released from its engagement with the first and second tooth rows by pushing the push rod, thus unlocking the lattice column.

[0033] Preferably, the top wall of the hanger has a hanging groove that mates with the second insert rod, and the top wall of the hanger is rotatably provided with a pressure plate. The pressure plate has a protrusion that corresponds to the sliding groove and protrudes outward. The pressure plate is used to lock the second insert rod, and the protrusion is used to insert into the sliding groove to limit the push rod. The pressure plate is provided with a second screw that passes through the pressure plate and is threaded onto the hanger.

[0034] The pressure plate effectively locks the second insert rod. When the pressure plate is tightened by the second screw, it presses the second insert rod firmly, preventing it from moving or falling off during the stress process, thereby enhancing the stability and safety of the connection.

[0035] Understandably, by setting the protrusion, when the pressure plate limits the second insert rod, the protrusion will insert into the sliding groove to form a secondary limit on the push rod, further improving the locking effect of the locking component. Attached Figure Description

[0046] To further understand the content of this invention, a detailed description of the invention is provided in conjunction with embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0047] Example 1 Please see Figure 1-3 This embodiment provides a positioning guide frame for vertical support lattice columns in deep foundation pits, which includes a guide frame body 100. The guide frame body 100 includes an operating platform 110 for being set above the borehole, a suspension assembly 220 for being set at the four corners of the outer wall of the lattice column 210, and a positioning assembly 120 that is detachably set at the operating platform 110 and extends into the lattice column 210. The positioning component 120 is used to form an axial lock on the inner wall of the lattice column 210, and the suspension component 220 is detachably provided at the positioning component 120 to position the axial elevation of the lattice column 210.

[0048] This disclosure discloses a positioning guide frame for vertical support lattice columns in deep foundation pits. In use, the operating platform 110 can be positioned above the borehole. When the lattice column 210 is lowered to the borehole position, lifting components 310 are welded to the outer corners of the lattice column 210. Then, positioning components 120 are inserted into the inner side of the lattice column 210 and installed onto the operating platform 110, forming a fastening system between the positioning components 120 and the lattice column 210. Specifically, the side lengths of the rectangle enclosed by the positioning components 350 are adjusted, and the four corners of the angle steel 450 are secured to the inner wall of the lattice column 210, axially locking the lattice column 210. The lattice column 210 is then lowered until it reaches the design elevation. The suspension component 220 is fixed on the positioning component 120, and the angle of the positioning component 120 is adjusted so that the angle of the lattice column 210 corresponds to the angle of the main beam axis of the support beam, thereby controlling the elevation and axis angle of the lattice column 210. Compared with the prior art, the present invention has a simple structure, is easy to operate, and has high stability, which can meet the requirements of fast, efficient and precise installation. Through the cooperation of the positioning component 120 and the operating platform 110, the installation accuracy and stability of the lattice column 210 can be effectively guaranteed, which can facilitate the construction of the subsequent support beam, reduce the occurrence of node enlargement heads, effectively control the stress balance of the system, and improve the overall stability of the foundation pit support system.

[0049] In addition, the present invention has the advantages of strong adaptability and good adjustability, and can be adjusted and adapted according to lattice columns 210 of different sizes, which greatly improves the installation accuracy.

[0050] Among them, the guide frame body 100 can be used in conjunction with the circulating drilling rig to form a fixed system using the drilling rig's frame, which has broad application prospects.

[0051] Seen in Figure 4 In this embodiment, the operating platform 110 includes four L-shaped bottom beams 410, which together form a rectangle with adjustable side length. An adjustment plate 420 is connected between the ends of adjacent bottom beams 410. A first adjustment slot 421 is formed on the side wall of the adjustment plate 420. A first adjustment bolt 430 is detachably provided at the ends of adjacent bottom beams 410, passing through the first adjustment slot 421. The first adjustment bolt 430 is used to limit the movement between the adjustment plate 420 and the bottom beam 410.

[0052] The above structure allows the operating platform 110 to be quickly adjusted in size as needed to accommodate drilling and lattice column 210 installation requirements of different sizes.

[0053] Understandably, the combined use of the adjusting plate 420 and the first adjusting bolt 430 allows construction personnel to easily adjust the spacing between the bottom beams 410 as needed, thereby ensuring that the operating platform can be stably supported above the borehole, providing a stable working platform for the installation of the lattice column 210.

[0054] Seen in Figure 4 In this embodiment, the bottom beam 410 has a corner portion set at 90°, and the top wall of the bottom beam 410 is provided with a support plate 440 set along the diagonal of the corner portion. One end of the support plate 440 extends into the borehole and the other end extends into the borehole.

[0055] The above structure not only enhances the overall rigidity of the bottom beam 410, making the operating platform 110 more stable under stress, but also minimizes the space occupied by the support plate 440 in the internal space of the operating platform 110, and maximizes the connection area between the support plate 440 and the operating platform 110, thereby improving the installation and connection stability of the positioning component 120.

[0056] Seen in Figure 3 , Figure 4 and Figure 5 In this embodiment, the positioning component 120 includes four positioning members 350 corresponding to the four bottom beams 410. The positioning members 350 are slidably disposed at the support plate 440. The four positioning members 350 together form a rectangle with adjustable side length. A connecting component 360 for adjusting the spacing is provided between adjacent positioning members 350. The connecting assembly 360 includes a first connecting plate 510 and a second connecting plate 520 respectively disposed on the inner wall of adjacent angle steels 450. The first connecting plate 510 and the second connecting plate 520 are respectively formed on the side wall of the second connecting plate 510 and the second connecting plate 520. A second adjusting bolt 550 is detachably provided between the third adjusting groove 540 and the second adjusting groove 530. The second adjusting bolt 550 is used to guide and limit the first connecting plate 510 and the second connecting plate 520.

[0057] By using the first connecting plate 510, the second connecting plate 520 and the second adjusting bolt 550 in the connecting assembly 360, the spacing between adjacent positioning parts 350 can be easily adjusted to accommodate lattice columns 210 with different inner wall sizes.

[0058] Understandably, the side length of the rectangle formed by the positioning components 350 can be adjusted by pulling the positioning components 350, making the adjustment simple and quick.

[0059] Seen in Figure 4In this embodiment, the positioning member 350 includes a vertically arranged angle steel 450 that fits against the inner wall of the lattice column 210. An adjustment member 460 is formed on the outer wall of the angle steel 450 along the diagonal of the corner. The adjustment member 460 is used to adjust the position of the angle steel 450.

[0060] With the above structure, construction workers can quickly attach the angle steel 450 to the inner wall of the lattice column 210 using the adjusting piece 460. This structure can be quickly applied to lattice columns 210 with different inner wall sizes, and the adjusting piece 460 can be used for positioning to ensure a stable locking of the lattice column 210.

[0061] Seen in Figure 4 , Figure 6 , Figure 7 and Figure 8 In this embodiment, the adjusting member 460 includes a sliding plate 610 slidably disposed on the support plate 440. A groove 710 is formed on the top wall of the sliding plate 610 near the end of the angle steel 450. A first through-hole 720 is formed on the bottom wall of the groove 710. A circular hole 810 corresponding to the first through-hole 720 is formed at the end of the support plate 440. A positioning bolt 620 passing through the first through-hole 720 is detachably provided in the circular hole 810. A third opening 740 is formed on the bottom wall of the groove 710 away from the angle steel 450, located on both sides of the first opening 720. A threaded hole 820 corresponding to the third opening 740 is formed on the top wall of the support plate 440. A screw 630 is detachably provided in the groove 710, passing through the third opening 740 and threaded into the threaded hole 820. The screw 630 and the positioning bolt 620 are used together to guide and limit the sliding plate 610 along the length of the support plate 440.

[0062] By passing the positioning bolt 620 through the round hole 810 and the first through hole 720, the sliding plate 610 can be fixed at any position on the support plate 440, thereby achieving precise positioning of the angle steel 450.

[0063] Understandably, in addition to the guide limit provided by the positioning bolt 620, the screw 630 passes through the third port 740 and is threaded into the threaded hole 820, providing additional guide limit for the sliding plate 610. Through the double limit, the stability of the adjusting member 460 is enhanced, preventing the sliding plate 610 from moving or deforming during the force process, thereby ensuring the precise fit between the angle steel 450 and the inner wall of the lattice column 210.

[0064] Meanwhile, the use of positioning bolts 620 and screws 630 for connection facilitates the disassembly and installation of the positioning assembly 120, and makes it easy to replace the positioning bolts 620 and screws 630 when they are damaged, with low replacement costs.

[0065] Seen in Figure 2 , Figure 3 and Figure 4 In this embodiment, an extension column 830 is formed at the top wall of the support plate 440 corresponding to the first opening 720, penetrating the first opening 720. A hanging member 650 for cooperating with the suspension assembly 220 is detachably provided above the sliding plate 610. The suspension assembly 220 includes a hanging member 310 and a suspension member provided on the outer wall of the lattice column 210. The hanging member 310 has an insertion port that is perpendicular to the support plate 440. The suspension member has a first insertion rod 320 inserted into the insertion port and a second insertion rod 340 provided at the hanging member 650. Both ends of the second insertion rod 340 and the first insertion rod 320 are provided with a connecting rod 330.

[0066] The extension column 830 provided on the support plate 440 not only enhances the structural strength of the support plate 440 and the adjusting member 460, but also provides a reliable mounting point for the hanger 650, and provides additional guidance for the adjusting member 460 to slide on the support plate 440.

[0067] Understandably, the extension column 830 passes through the first opening 720, so that the hanger 650 is stably fixed above the sliding plate 610, and then cooperates with the suspension component 220 to achieve effective support for the lattice column 210.

[0068] By setting up the suspension assembly 220, the insertion port formed inside the hanging member 310 is set perpendicular to the support plate 440, which facilitates the insertion of the first insertion rod 320. At the same time, the second insertion rod 340 is connected to the hanging member 650, so that the suspension member can form a stable connection with the hanging member. The first insertion rod 320 and the second insertion rod 340 are connected by the suspension rod 330, which realizes the efficient suspension and installation of the lattice column 210, thereby facilitating the adjustment of the elevation of the lattice column 210.

[0069] By rationally arranging the number and position of the suspension rods 330, it can be ensured that the lattice column 210 maintains a stable posture during installation, preventing deformation or tilting caused by uneven stress.

[0070] Example 2 Seen in Figure 6-9 This embodiment also provides a positioning guide frame for a vertical support lattice column in a deep foundation pit. The difference between this and embodiment 1 is that a locking component 640 is detachably provided at the support plate 440. The locking component 640 is used to form a one-way limit on the sliding plate 610. A second opening 730 is formed at the bottom wall of the groove 710, located on both sides of the first opening 720. The locking assembly 640 includes a housing 910 disposed above the sliding plate 610, and the bottom wall of the housing 910 has a fixing foot that is detachably disposed at the top wall of the support plate 440 through the second through-hole 730.

[0071] By setting the locking component 640, the movement of the sliding plate 610 on the support plate 440 is restricted in one direction, thereby ensuring that the sliding plate 610 can be pulled outward, thus preventing the sliding plate 610 from being pulled back, causing the angle steel 450 to disengage from the locking of the inner wall of the lattice column 210, which would affect the installation accuracy.

[0072] It is understood that the locking assembly 640 includes a housing 910 located above the sliding plate 610. The fixing foot formed by the bottom wall of the housing can pass through the second opening 730 and be detachably located on the top wall of the support plate 440. This not only makes the installation and removal of the locking assembly 640 very convenient, but also provides additional guidance and limiting function for the sliding plate 610.

[0073] Seen in Figure 7 and Figure 9 In this embodiment, a first toothed section 750 located between the second opening 730 and the first opening 720 and a second toothed section 760 located between the third opening 740 are formed on the bottom wall of the groove 710. The first toothed section 750 and the second toothed section 760 are continuously arranged. The housing 910 has an internal mounting cavity, and a ratchet 920 is rotatably provided in the mounting cavity to cooperate with the first tooth row 750 and the second tooth row 760. The ratchet 920 is used to unidirectionally limit the sliding plate 610 in the drilling direction. A spring 930 is provided between the top wall of the ratchet 920 and the inner wall of the mounting cavity. The spring 930 is used to provide elastic force to keep the ratchet 920 pressed downward. A push rod 940 for rotating the ratchet 920 is provided at the top wall of the ratchet 920. A sliding groove 950 for rotating the push rod 940 is formed at the top wall of the housing 910.

[0074] The ratchet 920 is configured to engage with the first toothed section 750 and the second toothed section 760, thereby forming a one-way limit on the sliding plate 610 in the drilling direction. In addition, the spring 930 ensures that the ratchet 920 is always engaged with the first toothed section 750 and the second toothed section 760, so that the angle steel 450 can be locked after the sliding plate 610 is pulled, making the operation simple and quick.

[0075] Understandably, after construction is completed, the ratchet 920 can be released from engagement with the first tooth row 750 and the second tooth row 760 by pushing the push rod 940, thereby releasing the lock on the lattice column 210.

[0076] Seen in Figure 3 , Figure 6 and Figure 10In this embodiment, a hanging groove 1010 is formed on the top wall of the hanging member 650 to cooperate with the second insert rod 340. A pressure plate 1020 is rotatably provided on the top wall of the hanging member 650. A protrusion 1030 is formed on the pressure plate 1020, which corresponds to the sliding groove 950 and protrudes outward. The pressure plate 1020 is used to lock the second insert rod 340. The protrusion 1030 is used to insert into the sliding groove 950 to limit the push rod 940. A second screw 1040 is provided on the pressure plate 1020 and threaded into the hanging member 650.

[0077] The pressure plate 1020 effectively locks the second insertion rod 340. When the pressure plate 1020 is tightened by the second screw 1040, it presses the second insertion rod 340 tightly, preventing it from moving or falling off during the force process, thereby enhancing the stability and safety of the connection.

[0078] It is understandable that by setting the protrusion 1030, when the pressure plate 1020 limits the second insertion rod 340, the protrusion 1030 will insert into the sliding groove 950 to form a secondary limit on the push rod 940, which further improves the locking effect of the locking component 640.

[0079] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, all of which do not exceed the protection scope of this application.

[0080] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the embodiments shown are only part of the embodiments of the present invention. The actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, they should all fall within the protection scope of the present invention.
