Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a positioning guide frame for vertically supporting lattice columns in a deep foundation pit. Background Art

[0002] With the development of cities, the construction land is reduced, and the development and utilization of underground space shows a trend of large-scale development. Various ultra-large-scale deep foundation pits are common. Foundation pit engineering has become a key link in the construction of projects. The safety and stability of foundation pit engineering is extremely important to the surrounding buildings and the environment. During the construction of lattice columns, it is necessary to effectively control indicators such as the top surface elevation, verticality, angle deviation with the axis of the support beam, and the depth of the inserted column piles to avoid improper construction measures, which will cause large deviations in the lattice columns, affect the construction of the horizontal reinforced concrete support system, and affect the force of the entire foundation pit support system. Therefore, during the foundation pit construction process, the construction quality control of the lattice columns, which are the key vertical support system, becomes the focus.

[0003] The installation of existing lattice columns requires the use of various auxiliary tools to ensure the accuracy and stability of the installation. However, most of the existing installation tools have complex structures, which makes the operation inconvenient and cannot meet the requirements of fast, efficient and accurate installation. Therefore, it is necessary to develop a lattice column guide frame with simple structure, convenient operation and high stability. Summary of the invention

[0004] The invention provides a positioning guide frame for vertically supporting lattice columns of a deep foundation pit, which can overcome certain defects of the prior art.

[0005] A positioning guide frame for vertically supporting lattice columns in a deep foundation pit according to the present invention comprises a guide frame body, wherein the guide frame body comprises an operating platform for being arranged above a drill hole, a suspension assembly for being arranged at four corners of an outer wall of the lattice column, and a positioning assembly detachably arranged at the operating platform and extending into the lattice column; The positioning assembly is used to form an axial locking on the inner wall of the lattice column, and the suspension assembly is used to be detachably arranged at the positioning assembly to form a positioning on the axial elevation of the lattice column.

[0006] The present invention has a simple structure, is easy to operate, and has high stability, and can meet the requirements of fast, efficient, and precise installation. Through the coordinated use of positioning components and an operating platform, the installation accuracy and stability of lattice columns can be effectively guaranteed, and convenience can be provided for the construction of subsequent support beams, and the occurrence of node enlargement heads can be reduced, and the force balance of the system can be effectively controlled, thereby improving 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 according to lattice columns of different sizes, thereby greatly improving the installation accuracy.

[0008] Preferably, the operating platform includes four L-shaped bottom beams, which together enclose a rectangle with adjustable side lengths, an adjustment plate is connected between adjacent bottom beam ends, a first adjustment slot is formed at the side wall of the adjustment plate, and a first adjustment bolt that passes through the first adjustment slot is detachably provided at the adjacent bottom beam ends, and the first adjustment bolt is used to form a limit between the adjustment plate and the bottom beam.

[0009] Through the above structure, the size of the operating platform can be quickly adjusted as needed to adapt to the installation requirements of drilling holes and lattice columns of different sizes.

[0010] It can be understood that the coordinated use of the adjustment plate and the first adjustment bolt allows construction personnel to easily adjust the spacing between the bottom beams as needed, thereby ensuring that the operating platform can be firmly supported above the drill hole, providing a stable working platform for the installation of the lattice column.

[0011] Preferably, the bottom beams all have a corner portion arranged at an angle of °, and the top wall of the bottom beams is provided with a support plate arranged along the diagonal of the corner portion, one end of the support plate extends into the inside of the drilled hole, and the other end extends to the outside of the drilled hole.

[0012] Through the above structure, the overall rigidity of the bottom beam is enhanced, making the operating platform more stable when subjected to force, and the support plate's occupation of the internal space of the operating platform is minimized, while the connection area between the support plate and the operating platform is maximized, thereby improving the installation and connection stability of the positioning assembly.

[0013] Preferably, the positioning assembly includes four positioning members arranged corresponding to the four bottom beams, the positioning members are slidably arranged at the support plate, the four positioning members together enclose a rectangle with adjustable side length, and a connecting assembly for adjusting the spacing is provided between adjacent positioning members; The connecting assembly includes a first connecting plate and a second connecting plate respectively arranged on the inner walls of adjacent angle steels, and a third adjustment slot and a second adjustment slot are respectively formed on the side walls of the first connecting plate and the second connecting plate. A second adjusting bolt is detachably arranged between the third adjusting slot and the second adjusting slot, and the second adjusting bolt is used to form a guide limit for 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 in coordination, the spacing between adjacent positioning members can be conveniently adjusted to adapt to lattice columns with different inner wall sizes.

[0015] It can be understood that the side length of the rectangle enclosed by the positioning pieces can be adjusted by pulling the positioning pieces, and the adjustment is simple and fast.

[0016] Preferably, the positioning member comprises an angle steel arranged vertically and in contact with the inner wall of the lattice column, and an adjusting member arranged along the diagonal line of the corner portion is formed on the outer wall of the angle steel, and the adjusting member is used to adjust the position of the angle steel.

[0017] Through the above structure, construction workers can quickly fit the angle steel to the inner wall of the lattice column through the adjusting piece, which can be quickly adapted to lattice columns with different inner wall sizes, and positioned through the adjusting piece to ensure stable locking of the lattice column.

[0018] Preferably, the adjusting member comprises a sliding plate slidably arranged at the supporting plate, a groove is formed at the top wall of the sliding plate near one end of the angle steel, a first opening is formed at the bottom wall of the groove, a circular hole corresponding to the first opening is formed at the end of the supporting plate, and a positioning bolt penetrating the first opening is detachably arranged in the circular hole; A third opening is formed on the bottom wall of the groove away from one end of the angle steel and located on both sides of the first opening, and a threaded hole corresponding to the third opening is formed on the top wall of the support plate. A screw that passes through the third opening and is threaded in the threaded hole is detachably provided at the groove, and the screw and the positioning bolt are used together to form a guide limit for the sliding plate along the length direction of the support plate.

[0019] By passing the positioning bolt through the circular hole and the first through opening, the sliding plate can be fixed at any position on the supporting plate, thereby realizing accurate positioning of the angle steel.

[0020] It can be understood that in addition to the guide limit provided by the positioning bolt, the screw passes through the third opening and is threaded into the threaded hole, providing an additional guide limit for the sliding plate. Through the double limit, the stability of the adjusting member is enhanced, and the sliding plate is prevented from moving or deforming during the force application process, thereby ensuring the precise fit between the angle steel and the inner wall of the lattice column.

[0021] At the same time, since positioning bolts and screws are used for connection, it is convenient to disassemble and install the positioning components. When the positioning bolts and screws are damaged, they are also easy to replace, and the replacement cost is low.

[0022] Preferably, an extension column passing through the first through opening is formed at the top wall corresponding to the support plate and the first through opening, and a hanger for cooperating with the suspension assembly is detachably provided above the sliding plate. The suspension assembly includes a hanger provided on the outer wall of the lattice column and a suspension member, and a socket vertically arranged with the support plate is formed inside the hanger. The suspension member has a first plug rod inserted in the socket and a second plug rod provided at the hanger, and both ends of the second plug rod and the first plug rod are provided with suspension rods for connection.

[0023] The extension column arranged on the support plate not only enhances the structural strength of the support plate and the adjusting member, but also provides a reliable installation point for the hanging member and provides additional guidance for the adjusting member to slide on the support plate.

[0024] It can be understood that the extension column passes through the first opening, so that the hanger is stably fixed above the sliding plate, and then cooperates with the suspension assembly to achieve effective support for the lattice column.

[0025] By setting up the suspension assembly, the socket formed inside the hanger is vertically arranged with the support plate, so as to facilitate the insertion of the first plug rod. At the same time, the second plug rod is connected with the hanger, so that the hanger can form a stable connection with the hanger. The first plug rod and the second plug rod are connected by the suspension rod, so as to realize the efficient suspension and installation of the lattice column, thereby facilitating the adjustment of the elevation of the lattice column.

[0026] Among them, by reasonably arranging the number and position of the hangers, it is possible to ensure that the lattice column maintains a stable posture during the installation process and prevent deformation or tilting due to uneven force.

[0027] Preferably, a locking assembly is detachably provided at the support plate, and the locking assembly is used to form a one-way limit for the sliding plate, and second openings located on both sides of the first opening are formed at the bottom wall of the groove; The locking assembly comprises a shell body arranged above the sliding plate, and a fixing foot which penetrates through a second through-hole and is detachably arranged on the top wall of the supporting plate is formed on the bottom wall of the shell body.

[0028] By setting the locking assembly, the movement of the sliding plate on the supporting plate is restricted in one direction, thereby ensuring that the sliding plate can be pulled outward, thereby preventing the sliding plate from being pulled back, causing the angle steel to be separated from the lock on the inner wall of the lattice column, affecting the installation accuracy.

[0029] It can be understood that the locking assembly includes a shell arranged above the sliding plate, and the fixed foot formed on the bottom wall of the shell can pass through the second opening and be detachably arranged on the top wall of the support plate, which not only makes the installation and disassembly of the locking assembly very convenient, but also provides additional guiding and limiting functions for the sliding plate.

[0030] Preferably, a first tooth row portion located between the second opening and the first opening and a second tooth row portion located between the third opening are formed at the bottom wall of the groove, and the first tooth row portion and the second tooth row portion are continuously arranged; An installation cavity is formed inside the shell, and a ratchet that cooperates with the first tooth row part and the second tooth row part is rotatably provided in the installation cavity. The ratchet is used to form a one-way limit for the sliding plate in the drilling 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 an elastic force to keep the ratchet pressed downward. A push rod for rotating the ratchet is provided at the top wall of the ratchet, and a sliding groove for rotating the push rod is formed at the top wall of the shell.

[0031] The ratchet is arranged in cooperation with the first tooth row portion and the second tooth row portion to form a one-way limit on the sliding plate in the drilling direction. In addition, through the setting of the spring, the ratchet is always in cooperation with the first tooth row portion and the second tooth row portion, so that the angle steel can be locked after the sliding plate is pulled, and the operation is simple and fast.

[0032] It is understandable that after the construction is completed, the ratchet can be released from the cooperation with the first tooth row part and the second tooth row part by pushing the push rod, so that the locking of the lattice column can be released.

[0033] Preferably, a hanging groove cooperating with the second insertion rod is formed on the top wall of the hanger, and a pressure plate is rotatably provided on the top wall of the hanger, and a convex portion corresponding to the sliding groove and protruding outward is formed on the pressure plate, the pressure plate is used to lock the second insertion rod, and the convex portion is used to be inserted into the sliding groove to limit the push rod, and a second screw is provided on the pressure plate with a thread penetrating through the pressure plate and arranged on the hanger.

[0034] By setting the pressure plate, the second plug rod can be effectively locked. When the pressure plate is tightened by the second screw, it will tightly press the second plug rod to prevent it from moving or falling off during the force application process, thereby enhancing the stability and safety of the connection.

[0035] It can be understood that, by setting the convex portion, when the pressure plate limits the second insertion rod, the convex portion will be inserted into the sliding groove to form a secondary limit for the push rod, further improving the locking effect of the locking assembly.

[0046] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0047] Example 1 See also Figure 1-3 The present embodiment provides a positioning guide frame for vertically supporting lattice columns in a deep foundation pit, which includes a guide frame body 100, the guide frame body 100 includes an operating platform 110 for being arranged above a drilling hole, a suspension assembly 220 for being arranged at four corners of the outer wall of the lattice column 210, and a positioning assembly 120 detachably arranged at the operating platform 110 and extending into the lattice column 210; The positioning assembly 120 is used to axially lock the inner wall of the lattice column 210 , and the suspension assembly 220 is used to be detachably disposed at the positioning assembly 120 to position the axial elevation of the lattice column 210 .

[0048] The present invention discloses a positioning guide frame for vertically supporting lattice columns in a deep foundation pit. When in use, an operating platform 110 can be set above a drilling hole. When the lattice column 210 is lowered to the drilling position, hangers 310 are welded outside the four corners of the lattice column 210, and then the positioning assembly 120 is inserted into the inner side of the lattice column 210. The positioning assembly 120 is installed on the operating platform 110, so that the positioning assembly 120 and the lattice column 210 form a fastening system, that is, the side length of the rectangle enclosed by the positioning piece 350 is adjusted, and the four corners of the angle steel 450 are clamped on the inner wall of the lattice column 210 to form an axial locking for the lattice column 210, and then the lattice column 210 is lowered. When the lattice column 210 is lowered to the designed elevation, , fix the suspension assembly 220 on the positioning assembly 120, and adjust the angle of the positioning assembly 120 to make the angle of the lattice column 210 correspond to the angle of the axis of the main beam of the support beam, so as to achieve the effect of controlling the elevation and axis angle of the lattice column 210. Compared with the prior art, the present invention has a simple structure, convenient operation, high stability, and can meet the needs of fast, efficient and precise installation. Through the coordinated use of the positioning assembly 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 subsequent support beams, reduce the occurrence of node enlargement heads, effectively control the force 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, thereby greatly improving the installation accuracy.

[0050] The guide frame body 100 can be used in conjunction with a circulating drilling rig, and the machine frame of the drilling rig can be used to form a fixing system, which has a wide range of application prospects.

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

[0052] Through the above structure, the size of the operating platform 110 can be quickly adjusted as needed to adapt to the installation requirements of drilling holes and lattice columns 210 of different sizes.

[0053] It is understandable that the use of the adjustment plate 420 and the first adjustment 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 firmly supported above the drill hole, providing a stable working platform for the installation of the lattice column 210.

[0054] See Figure 4 In this embodiment, the bottom beam 410 has a corner portion set at 90°, and a support plate 440 is provided on the top wall of the bottom beam 410 along the diagonal of the corner portion. One end of the support plate 440 extends to the inside of the drill hole, and the other end extends to the outside of the drill hole.

[0055] Through the above structure, the overall rigidity of the bottom beam 410 is enhanced, making the operating platform 110 more stable when subjected to force, and the occupation of the internal space of the operating platform 110 by the support plate 440 is minimized, while the connection area between the support plate 440 and the operating platform 110 is maximized, thereby improving the installation and connection stability of the positioning assembly 120.

[0056] See Figure 3 , Figure 4 and Figure 5 In this embodiment, the positioning assembly 120 includes four positioning members 350 corresponding to the four bottom beams 410. The positioning members 350 are slidably arranged at the support plate 440. The four positioning members 350 together enclose a rectangle with adjustable side lengths. A connecting assembly 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 which are respectively arranged on the inner walls of adjacent angle steels 450, and a third adjustment groove 540 and a second adjustment groove 530 are respectively formed on the side walls of the first 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, and the second adjusting bolt 550 is used to form a guide limit for 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 members 350 can be conveniently adjusted to adapt to lattice columns 210 with different inner wall sizes.

[0058] It can be understood that the side length of the rectangle enclosed by the positioning members 350 can be adjusted by pulling the positioning members 350 , and the adjustment is simple and fast.

[0059] See Figure 4In this embodiment, the positioning member 350 includes a vertically arranged angle steel 450 that is in contact with the inner wall of the lattice column 210 , and an adjusting member 460 arranged along the diagonal line of the corner portion is formed on the outer wall of the angle steel 450 , and the adjusting member 460 is used to adjust the position of the angle steel 450 .

[0060] Through the above structure, construction workers can quickly fit the angle steel 450 to the inner wall of the lattice column 210 through the adjustment piece 460, which can be quickly adapted to lattice columns 210 with different inner wall sizes, and positioned through the adjustment piece 460 to ensure stable locking of the lattice column 210.

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

[0062] The sliding plate 610 can be fixed at any position on the supporting plate 440 by passing the positioning bolt 620 through the circular hole 810 and the first through hole 720 , thereby realizing accurate positioning of the angle steel 450 .

[0063] It can be understood that in addition to the guide limit provided by the positioning bolt 620, the screw 630 passes through the third opening 740 and is threadedly connected in the threaded hole 820, providing an additional guide limit for the sliding plate 610. Through the double limit, the stability of the adjustment member 460 is enhanced, and the sliding plate 610 is prevented from moving or deforming during the force application process, thereby ensuring the precise fit between the angle steel 450 and the inner wall of the lattice column 210.

[0064] At the same time, since the positioning bolts 620 and screws 630 are used for connection, it is convenient to disassemble and install the positioning assembly 120. When the positioning bolts 620 and screws 630 are damaged, they are easy to replace, and the replacement cost is low.

[0065] See Figure 2 , Figure 3 and Figure 4 In this embodiment, an extension column 830 is formed at the top wall corresponding to the support plate 440 and the first opening 720, and the extension column 830 passes through the first opening 720. A hanger 650 for cooperating with the suspension assembly 220 is detachably provided above the sliding plate 610. The suspension assembly 220 includes a hanger 310 and a suspension member provided on the outer wall of the lattice column 210. A socket is formed inside the hanger 310 and is vertically arranged with respect to the support plate 440. The suspension member has a first plug rod 320 inserted in the socket and a second plug rod 340 provided at the hanger 650. Both ends of the second plug rod 340 and the first plug rod 320 are provided with a suspension rod 330 for connection.

[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 installation point for the hanger 650 and provides additional guidance for the adjusting member 460 to slide on the support plate 440 .

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

[0068] By setting the suspension component 220, the socket formed inside the hanger 310 is set perpendicular to the support plate 440, which is convenient for inserting the first plug rod 320. At the same time, the second plug rod 340 is connected to the hanger 650, so that the suspension can form a stable connection with the hanger. The first plug rod 320 and the second plug rod 340 are connected by the suspension rod 330, so that the lattice column 210 is efficiently suspended and installed, thereby facilitating the adjustment of the elevation of the lattice column 210.

[0069] Among them, by reasonably arranging the number and position of the suspension rods 330, it is possible to ensure that the lattice column 210 maintains a stable posture during the installation process, and prevent deformation or tilting due to uneven force.

[0070] Example 2 See Figure 6-9 This embodiment also provides a positioning guide frame for vertically supporting lattice columns in a deep foundation pit, which differs from the first embodiment in that: a locking assembly 640 is detachably provided at the support plate 440, and the locking assembly 640 is used to form a one-way limit for the sliding plate 610, and a second through hole 730 located on both sides of the first through hole 720 is formed at the bottom wall of the groove 710; The locking assembly 640 includes a housing 910 disposed above the sliding plate 610 . A fixing foot is formed on the bottom wall of the housing 910 and passes through the second through hole 730 and is detachably disposed on the top wall of the supporting plate 440 .

[0071] By setting the locking assembly 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, thereby preventing the sliding plate 610 from being pulled back, causing the angle steel 450 to be disengaged from the lock on the inner wall of the lattice column 210, affecting the installation accuracy.

[0072] It can be understood that the locking assembly 640 includes a shell 910 arranged above the sliding plate 610, and the fixed foot formed on the bottom wall of the shell can pass through the second opening 730 and be detachably arranged on the top wall of the support plate 440, which not only makes the installation and disassembly of the locking assembly 640 very convenient, but also provides additional guiding and limiting functions for the sliding plate 610.

[0073] See Figure 7 and Fig. 9 In this embodiment, a first tooth row portion 750 located between the second opening 730 and the first opening 720 and a second tooth row portion 760 located between the third opening 740 are formed at the bottom wall of the groove 710, and the first tooth row portion 750 and the second tooth row portion 760 are continuously arranged; An installation cavity is formed inside the shell 910, and a ratchet 920 that cooperates with the first tooth row portion 750 and the second tooth row portion 760 is rotatably provided in the installation cavity. The ratchet 920 is used to form a one-way limit for 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 installation cavity. The spring 930 is used to provide an 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, and a sliding groove 950 for rotating the push rod 940 is formed at the top wall of the shell 910.

[0074] The ratchet 920 is arranged in coordination with the first tooth row portion 750 and the second tooth row portion 760 to form a one-way limit on the sliding plate 610 in the drilling direction. In addition, through the setting of the spring 930, the ratchet 920 is always in coordination with the first tooth row portion 750 and the second tooth row portion 760, so that the angle steel 450 can be locked after the sliding plate 610 is pulled, and the operation is simple and fast.

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

[0076] See Figure 3 , Figure 6 and Fig.10In this embodiment, a hanging groove 1010 cooperating with the second insertion rod 340 is formed at the top wall of the hanger 650, and a pressure plate 1020 is rotatably provided at the top wall of the hanger 650. A convex portion 1030 corresponding to the sliding groove 950 and protruding outward is formed at the pressure plate 1020. The pressure plate 1020 is used to lock the second insertion rod 340, and the convex portion 1030 is used to be inserted into the sliding groove 950 to limit the push rod 940. The pressure plate 1020 is provided with a second screw 1040 that passes through the pressure plate 1020 and is threaded at the hanger 650.

[0077] By setting the pressure plate 1020, the second plug rod 340 can be effectively locked. When the pressure plate 1020 is tightened by the second screw 1040, it will tightly press the second plug rod 340 to prevent it from moving or falling off during the force application process, thereby enhancing the stability and safety of the connection.
