Description

Technical Field

[0001] The present application relates to the field of building construction, and in particular to a purlin support that is easy to disassemble and assemble. Background Art

[0002] During the construction process of a pile cap foundation, sheet piles need to be driven. A sheet pile is a steel structure that can be freely combined to form a continuous and tight retaining wall or water retaining wall, with a linkage device at its edge. In order to ensure the verticality of the sheet pile driving and the flatness of the wall surface of the driven sheet pile wall, a purlin support should be set when driving the sheet pile. The purlin support adopts a double-sided layout form. If higher requirements are imposed on the driving of the sheet pile, it can be arranged in two layers or multiple layers along the height, which will have a better guiding effect when driving the sheet pile.

[0003] The existing purlin support in the prior art includes two main supports and multiple secondary supports. The main supports are perpendicular to the ground, and the secondary supports are located between the two main supports. Multiple secondary supports are arranged along the length direction of the main supports, and the number of secondary supports is determined according to construction requirements; both ends of the secondary supports are fixed to the two main supports respectively, and the main supports and the secondary supports are fixedly connected by welding through connecting plates.

[0004] In actual use, both the sheet pile and the purlin support can be reused. However, the main support and the secondary support are fixedly connected by welding through a connecting plate. After disassembly, the purlin support is not easy to transport, and the size of the purlin support may not meet the needs of other constructions. If the fixation between the main support and the secondary support is forcibly released, the main support and the secondary support will be damaged greatly. Summary of the Invention

[0005] In order to facilitate the disassembly and assembly between the main support and the secondary support, the present application provides a purlin support that is easy to disassemble and assemble.

[0006] A purlin support that is easy to disassemble and assemble provided by the present application adopts the following technical solution:

[0007] A purlin support that is easy to disassemble and assemble includes two main supports and several secondary supports. The secondary supports are located between the two main supports. The main supports are provided with fitting grooves for the ends of the secondary supports to be inserted into. A fixing plate is slidably connected to the main supports. Fixing grooves are respectively provided on the outer peripheral walls at both ends of the secondary supports. After the secondary supports are inserted into the fitting grooves, the fixing plate can be inserted into the fixing grooves. The cooperation between the fixing plate and the fixing grooves is used to prevent the main supports from sliding out of the fitting grooves easily. A control member for controlling the sliding of the fixing plate is provided on the main supports.

[0008] By adopting the above technical solution, when the main bracket and the secondary bracket are fixed, first drive the fixed plate to slide out of the fitting groove through the control member. After the end of the secondary bracket is inserted into the fitting groove, then drive the fixed plate to slide into the fixing groove on the secondary bracket through the control member, thereby restricting the secondary bracket from sliding outwards towards the fitting groove. Only by operating the control member can the fixing and unlocking between the main bracket and the secondary bracket be realized, which facilitates the disassembly and assembly between the main bracket and the secondary bracket.

[0009] Preferably, the secondary bracket includes a connecting rod and a telescopic rod. The connecting rod is slidably connected to the telescopic rod. A connecting threaded hole for the telescopic rod to slide is provided on the connecting rod. A connecting thread matching the connecting threaded hole is provided on the outer peripheral wall of the telescopic rod.

[0010] By adopting the above technical solution, when the installation work of the waling bracket is about to end, the length of the last construction path can be measured first, and then the distance between the connecting rod and the telescopic rod can be adjusted by rotating the connecting rod to ensure the length of the waling bracket. There is no need to make additional protection, which improves the applicability and convenience of the waling bracket.

[0011] Preferably, a rotating disk is rotatably connected to the main bracket. A rotating groove for the rotating disk to rotate is provided on the main bracket. The rotating groove communicates with both the storage cavity and the fitting groove. An installation block is coaxially fixed on the rotating disk. An installation groove matching the installation block is provided at the end of the main bracket. A locking component for locking the rotating disk is provided on the main bracket.

[0012] By adopting the above technical solution, with the cooperation of the installation block and the installation groove, the connection strength between the connecting rod and the main bracket is improved. Since the rotating disk is rotatably connected to the main bracket, after the connecting rod and the main bracket are fixed, the distance between the connecting rod and the telescopic rod can be directly adjusted without separating the connecting rod from the main bracket. After the adjustment is completed, the rotation of the rotating disk can be locked through the locking component, thereby locking the distance between the connecting rod and the telescopic rod, which is convenient for adjusting the distance between the connecting rod and the telescopic rod.

[0013] Preferably, the locking component includes a locking disk slidably connected to the main bracket. The locking disk is coaxially arranged with the rotating disk. The locking disk is slidably arranged in the storage cavity. A plurality of locking grooves are provided on the rotating disk. The plurality of locking grooves are arranged in a circumferential array with the axis of the rotating disk as the center. A locking column is slidably connected to the locking disk. A placement groove for the locking column to slide is provided on the locking disk. A locking elastic member for pushing the locking column to slide outwards towards the outside of the placement groove is provided on the locking disk. After the locking disk slides, the locking column is inserted into the locking groove. A matching member for driving the locking disk to slide is provided on the main bracket.

[0014] By adopting the above technical solution, the locking plate slides down to the locking column and embeds into the locking groove under the action of the matching piece, thereby locking the rotation of the rotating plate in the main bracket, making it difficult for the connecting rod to rotate relative to the main bracket, thereby locking the distance between the connecting rod and the telescopic rod, and completing the adjustment of the purlin bracket; the number of locking grooves and locking columns can be controlled to control the adjustable length interval between the telescopic rod and the connecting rod; in actual use, only part of the locking columns can be embedded in the locking groove under the action of the locking elastic member, and the remaining locking columns will be squeezed into the placement groove under the action of the rotating plate.

[0015] Preferably, the main bracket is provided with a ground-breaking cone, and a storage cavity for accommodating the ground-breaking cone is opened on the main bracket, the storage cavity runs through the bottom of the main bracket, the ground-breaking cone is slidably arranged in the storage cavity, the main bracket is provided with a sliding assembly for controlling the sliding of the ground-breaking cone on the main bracket, the bottom end of the main bracket is rotatably connected to a closing plate for controlling the opening and closing of the storage cavity, and the main bracket is provided with a rotating assembly for driving the closing plate to rotate.

[0016] By adopting the above technical solution, the earth-breaking cone slides under the action of the sliding assembly and is embedded in the soil of the foundation pit, which makes it easy to fix the purlin bracket at a preset point of the foundation pit; through the setting of the closing plate, when the purlin bracket is idle, it is not easy for construction workers to contact the earth-breaking cone in the main bracket, thereby improving the safety of the purlin bracket. External impurities are not easy to enter the storage cavity, causing the storage cavity to be blocked or accelerating the corrosion of the earth-breaking part, thereby effectively extending the service life of the earth-breaking cone.

[0017] Preferably, the mating part includes a driving block arranged at one end of the locking disk away from the rotating disk, a driving groove is opened on the outer wall of the earth-breaking cone, the driving block is slidably arranged in the driving groove, the inner wall of the driving groove is provided with an inclined surface, when the earth-breaking cone slides toward the outside of the storage cavity, the driving block slides along the inclined surface, and after the driving block slides, the locking disk slides toward the rotating disk.

[0018] By adopting the above technical solution, with the cooperation between the driving block and the inclined surface in the driving groove, when in the initial state, the driving block is located in the driving groove, and the rotating disk can rotate relative to the main bracket. When the earth-breaking cone slides toward the outside of the storage cavity under the action of the sliding assembly, the driving block slides along the inclined surface and pushes the locking disk to slide toward the rotating disk, thereby locking the rotation of the rotating disk. No other driving source is required, saving energy.

[0019] Preferably, a positioning column is slidably connected inside the main bracket, and a plurality of positioning grooves for the positioning column to slide and embed into are opened on the outer peripheral wall of the rotating disk. The plurality of positioning grooves are arranged in a circular array with the axis of the locking disk as the center, and the inner walls adjacent to the positioning grooves are inclined. When the rotating disk rotates, the positioning column slides in the positioning groove, and after the positioning column is embedded in the positioning groove, the locking column corresponds to the locking groove.

[0020] By adopting the above technical solution, under the cooperation of the positioning post and the positioning groove, the positioning post will slide under its own gravity to be completely embedded in the positioning groove, so that when the rotating disc rotates to a position where the locking post can be embedded in the locking groove when the locking disc slides, the reliability of restricting the rotation of the rotating disc through the cooperation of the locking post and the locking groove is improved; since the adjacent inner walls of the positioning groove are inclined, it is convenient for the positioning post to slide in and out of the positioning groove.

[0021] Preferably, a plurality of guide posts are provided on the locking disc, guide grooves for the guide posts to slide are formed on the inner wall of the storage cavity, and a reset elastic member for pushing the guide posts to slide out of the guide grooves is provided on the main bracket.

[0022] By adopting the above technical solution, under the cooperation of the guide posts and the guide grooves, the locking disc is not likely to rotate relative to the main bracket, and the sliding track of the locking disc on the main bracket is defined, improving the stability of the locking disc sliding on the main bracket; through the setting of the reset elastic member, when the collar bracket is idle and the earth-breaking cone is stored in the storage cavity, the locking disc can slide under the action of the reset elastic member so that the driving block is embedded in the driving groove.

[0023] Preferably, the rotating assembly includes a control block connected to the main bracket, a control groove for storing the control block is formed on the main bracket, the control groove penetrates through the bottom of the main bracket, the control block is slidably arranged in the control groove, a rotating gear is provided on the closing plate, and a rotating rack meshing with the rotating gear is provided on the control block. When the control block slides to be embedded in the ground, the closing plate rotates to release the closing of the storage cavity, and a control elastic member for restricting the control block from sliding in a direction away from the control groove is provided on the main bracket.

[0024] By adopting the above technical solution, construction workers can drive the control block to slide towards the ground by stepping on it. Under the cooperation of the rotating gear and the rotating rack, when the control block slides to be embedded in the ground, the closing plate can be rotated to release the closing of the storage cavity. On the one hand, the closing of the storage cavity by the closing plate is released, and on the other hand, it makes a preliminary positioning for installing the collar bracket on the ground, improving the accuracy of installing the collar bracket; through the setting of the control elastic member, when the collar bracket is idle, the closing plate can keep the storage cavity closed.

[0025] Preferably, the sliding assembly includes a rotating block rotatably arranged in the main bracket, a screw and a control rod are coaxially provided on the rotating block, the control rod is located in the screw, a driving rod is slidingly connected to the control rod, the breaking cone includes a sliding part and a breaking part, the sliding part is provided with a sliding thread groove matched with the screw, the breaking part is rotatably connected to the sliding part, one end of the driving rod away from the control rod is fixed to the breaking part, and the screw and the control rod rotate synchronously when the rotating block rotates.

[0026] By adopting the above technical scheme, through the arrangement of the rotating block, the screw and the control block, the driving block can synchronously drive the screw and the control rod to rotate when it rotates, and the sliding part slides in the storage cavity when the screw rotates. When the control rod rotates, the driving rod drives the earth-breaking part to rotate, and there is only rotation between the earth-breaking part and the sliding part. When the sliding part drives the earth-breaking part to slide, the driving rod is displaced relative to the control rod, so that the earth-breaking part can slide relative to the main bracket while rotating, so that the earth-breaking part is easy to embed in the foundation pit soil.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. When the main bracket and the secondary bracket are fixed, the control member is used to first drive the fixing plate to slide out of the fitting groove. After the end of the secondary bracket is embedded in the fitting groove, the control member is used to drive the fixing plate to slide into the fixing groove embedded in the secondary bracket, thereby limiting the secondary bracket from sliding out of the fitting groove. The fixing and unlocking between the main bracket and the secondary bracket can be realized by operating the control member, which is convenient for the disassembly and assembly between the main bracket and the secondary bracket.

[0029] 2. Construction workers can drive the control block to slide toward the ground by stepping on it. With the cooperation of the rotating gear and the rotating rack, the control block slides to be embedded in the ground, which can make the closing plate rotate to release the sealing of the storage cavity.

Detailed implementation manners

[0040] The following will Figures 1-9 make a further detailed description of the present application with reference to the attached

[0041] The embodiment of the present application discloses a formwork support that is convenient for disassembly and assembly. Refer to Figure 1, including two main brackets 1 and several secondary brackets 2. The number of secondary brackets 2 depends on the construction requirements. In the embodiment of the present application, there are two secondary brackets 2. The structural descriptions in the subsequent text are all based on the premise of having two secondary brackets 2, and the structure can be adjusted according to the actual number of secondary brackets 2. The main bracket 1 is perpendicular to the foundation pit ground during installation. The secondary brackets 2 are located between the two main brackets 1 and are placed perpendicular to the main brackets 1. On the opposite side walls of the two main brackets 1, there are both fitting grooves 11 for the ends of the secondary brackets 2 to be inserted into. The inner diameter of the fitting groove 11 is the same as the outer diameter of the secondary bracket 2.

[0042] Referring to Figure 1 and Figure 2 , the secondary bracket 2 includes a connecting rod 21 and a telescopic rod 22. The connecting rod 21 is slidably connected to the telescopic rod 22, and the telescopic rod 22 slides along the length direction of the connecting rod 21. On the connecting rod 21, there is a connecting threaded hole 211 for the telescopic rod 22 to slide through. On the outer peripheral wall of the telescopic rod 22, there is a connecting thread 221 that cooperates with the connecting threaded hole 211. The outer diameter of the end of the telescopic rod 22 away from the connecting rod 21 is the same as the outer diameter of the connecting rod 21. When the installation work of the waling bracket is coming to an end, the length of the last construction path can be measured first, and then the distance between the connecting rod 21 and the telescopic rod 22 can be adjusted by rotating the connecting rod 21 to ensure the length of the waling bracket, without the need to make additional protection, improving the applicability and convenience of the waling bracket. During the adjustment process, the main bracket 1 fixed to the telescopic rod 22 can be manually controlled to keep the two main brackets 1 always in a parallel state.

[0043] Referring to Figure 1 and Figure 3 , a fixing plate 12 is slidably connected to the main bracket 1. The fixing plate 12 slides along the length direction of the main bracket 1. The fixing plate 12 is located above the fitting groove 11. On the main bracket 1, there is a sliding groove 121 for the fixing plate 12 to slide through. The sliding groove 121 is communicated with the fitting groove 11. On the outer peripheral walls of the ends of the connecting rod 21 and the telescopic rod 22, a fixing groove 23 is coaxially provided. The width of the fixing groove 23 is the same as the thickness of the fixing plate 12. One end of the fixing plate 12 close to the fitting groove 11 is arranged in an arc shape that matches the fixing groove 23. After the telescopic rod 22 and the connecting rod 21 are inserted into the corresponding fitting grooves 11 of the main bracket 1, the fixing plate 12 can be controlled to slide into the fitting groove 11, so that the telescopic rod 22 and the connecting rod 21 can be fixed to the corresponding main bracket 1.

[0044] Referring to Figure 3, a control member 13 for controlling the sliding of the fixing plate 12 is provided on the main support 1. The control member 13 includes two control pieces 131 which are slidably connected to the main support 1 and slide along the length direction of the main support 1. The two control pieces 131 are respectively located on both sides of the fixing plate 12, and all the fixing plates 12 are fixed to the control pieces 131. The top end of the control piece 131 penetrates through the main support 1, and the end of the control piece 131 outside the main support 1 is connected by a control column 132. Both ends of the control column 132 are fixed to the two control pieces 131 respectively, and a handle 133 is rotatably connected to the control column 132. Through the arrangement of the control column 132, the control piece 131 is restricted from sliding into the main support 1, and the control piece 131 is driven to slide synchronously by the handle 133, so that all the fixing plates 12 can be driven to slide synchronously, facilitating the locking of the sliding of the plurality of telescopic rods 22 and the connecting rod 21 relative to the main support 1.

[0045] Referring to Figure 3 , a ground-breaking cone 3 is slidably connected to the main support 1 and slides along the length direction of the main support 1. A receiving cavity 14 for receiving the ground-breaking cone 3 and allowing the ground-breaking cone 3 to slide is formed on the main support 1, and the receiving cavity 14 penetrates through the bottom of the main support 1. The ground-breaking cone 3 includes a sliding part 31 and a ground-breaking part 32. The sliding part 31 is arranged in a cuboid shape, and the ground-breaking part 32 is arranged in a conical auger shape. The sliding part 31 is slidably arranged in the receiving cavity 14, and the ground-breaking part 32 is rotatably connected to the sliding part 31. The shape of the ground-breaking part 32 facilitates the ground-breaking cone 3 to be embedded into the foundation pit soil, so that the fixed collar support can be fixed in the foundation pit.

[0046] Referring to Figure 3 and Figure 5 , a sliding assembly for controlling the sliding of the ground-breaking cone 3 on the main support 1 is provided on the main support 1. The sliding assembly includes a rotating block 15 rotatably connected to the main support 1. The rotating block 15 is located at the top end of the main support 1, and the top end of the rotating block 15 penetrates through the main support 1. A screw rod 151 and a control rod 152 are coaxially fixed on the rotating block 15. The screw rod 151 is located in the receiving cavity 14, and the control rod 152 is located inside the screw rod 151. A driving rod 153 is also slidably connected to the control rod 152. Both the driving rod 153 and the control rod 152 are square rods. The end of the driving rod 153 away from the control rod 152 penetrates through the screw rod 151, and a sliding thread groove 311 matching with the screw rod 151 is formed on the sliding part 31. The end of the driving rod 153 away from the control rod 152 penetrates through the screw rod 151. The top end of the rotating block 15 penetrates through the main support 1, and a square groove 154 is formed at the top end of the rotating block 15. An operator can prepare a square block matching with the square groove 154 and coaxially fix it to the output shaft of the rotating motor, and the rotating block 15 can be driven to rotate by the rotating motor, saving manpower.

[0047] The rotating block 15 is driven to rotate by rotating the motor. When the rotating block 15 rotates, it can synchronously drive the screw 151 and the control rod 152 to rotate. When the screw 151 rotates, the sliding part 31 slides in the storage chamber 14. When the control rod 152 rotates, the driving rod 153 drives the ground-breaking part 32 to rotate. There is only rotation between the ground-breaking part 32 and the sliding part 31. When the sliding part 31 drives the ground-breaking part 32 to slide, the driving rod 153 is displaced relative to the control rod 152.

[0048] Reference Figure 3 and Figure 4 The bottom end of the main bracket 1 is rotatably connected to a closing plate 16. After the closing plate 16 is rotated, the storage chamber 14 is connected to or closed off from the outside. By setting the closing plate 16, when the surrounding purlin bracket is idle, it is not easy for construction workers to contact the ground-breaking part 32 in the main bracket 1, thereby improving the safety of the surrounding purlin bracket. It is not easy for foreign matter to enter the storage chamber 14, causing the storage chamber 14 to be blocked or accelerating the corrosion of the ground-breaking part 32, thereby effectively extending the service life of the ground-breaking part 32.

[0049] Reference Figure 3 and Figure 4 The main bracket 1 is provided with a rotating assembly for driving the closing plate 16 to rotate, and the rotating assembly includes a control block 4 slidably arranged on the main bracket 1, and the control block 4 slides along the length direction of the main bracket 1. The main bracket 1 is provided with a control groove 17 for accommodating the control block 4 and for the control block 4 to slide. The control groove 17 runs through the bottom of the main bracket 1, and the control block 4 includes a first block 41 and a second block 42. The first block 41 is slidably arranged in the control groove 17, and the second block 42 is perpendicular to the first block 41, and the second block 42 extends to the outside of the main bracket 1 away from the first block 41. A closed groove 161 is provided on the inner wall of the storage cavity 14 for the closing plate 16 to be embedded after rotation, and a closed column 162 is fixed on the closing plate 16 for the closing plate 16 to rotate. The closing plate 16 is coaxially arranged with the axis of the closing column 162 as the center, and both ends of the closing plate 16 are rotatably connected to the inner wall of the closed groove 161.

[0050] Reference Figure 4 A rotating gear 163 is coaxially fixed on the closing column 162, and a rotating rack 411 meshing with the rotating gear 163 is fixed on the first block 41. One end of the first block 41 close to the opening of the control groove 17 is set in a cone shape. After placing the surrounding purlin bracket to the specified position, the construction personnel can step on the second block 42 located outside the main bracket 1 to drive the control block 4 to slide toward the ground. Under the cooperation of the rotating gear 163 and the rotating rack 411, the control block 4 slides to be embedded in the ground, which can make the closing plate 16 rotate to release the sealing of the storage chamber 14. On the one hand, the sealing of the storage chamber 14 by the closing plate 16 is released. On the other hand, it is used to make a preliminary positioning for installing the surrounding purlin bracket on the ground, thereby improving the accuracy of installing the surrounding purlin bracket.

[0051] A control elastic member for restricting the control block 4 from sliding in a direction away from the control groove 17 is provided on the main bracket 1. In the embodiment of the present application, the control elastic member is selected as a control torsion spring. The control torsion spring is sleeved on the rotating column. One end of the control torsion spring is fixed to the inner wall of the closed groove 161, and the other end of the control torsion spring is fixed to the closing plate 16. Through the arrangement of the control torsion spring, the closing plate 16 can maintain the state of closing the storage cavity 14 when the purlin bracket is not in use.

[0052] Refer to Figure 2 and Figure 6 , an installation block 111 is coaxially fixed on the inner wall of the fitting groove 11. Installation grooves 24 adapted to the installation block 111 are provided at the ends of the connecting rod 21 and the telescopic rod 22. Through the arrangement of the installation block 111, the connection strength between the telescopic rod 22 and the connecting rod 21 and the main bracket 1 is improved. In order to enable the connecting rod 21 to still rotate after being fixed to the main bracket 1, a rotating disk 5 is rotatably connected to the main bracket 1 fixed to the connecting rod 21. The installation block 111 on the main bracket 1 is coaxially fixed to the rotating disk 5. A rotating groove 51 for the rotating disk 5 to rotate is provided on the main bracket 1. The storage cavity 14 and the fitting groove 11 are both communicated with the rotating groove 51. The rotating disk 5 only rotates relative to the main bracket 1 and is not prone to sliding relative to the main bracket 1.

[0053] Refer to Figure 6 and Figure 7 , a locking assembly for locking the rotation of the rotating disk 5 is provided on the main bracket 1. The locking assembly includes a locking disk 6 slidably connected to the main bracket 1. The locking disk 6 is coaxially arranged with the rotating disk 5. The locking disk 6 is slidably arranged in the storage cavity 14 and slides along its own axis. A plurality of locking grooves 52 are provided at one end of the rotating disk 5 away from the installation block 111. The plurality of locking grooves 52 are divided into an inner ring groove 521 and an outer ring groove 522. The plurality of inner ring grooves 521 and outer ring grooves 522 are arranged in a circumferential array with the axis of the rotating disk 5 as the center. The outer ring groove 522 is located on the side of the inner ring groove 521 away from the axis of the rotating disk 5, and any one outer ring groove 522 is located between two adjacent inner ring grooves 521. In the embodiment of the present application, there are eight inner ring grooves 521 and outer ring grooves 522 respectively.

[0054] Refer to Figure 7, a locking column 61 is slidably connected to the locking disk 6. There are sixteen locking columns 61 which are divided into inner and outer circles. The locking columns 61 slide perpendicularly to the end face of the locking disk 6. A placement groove 62 for the locking columns 61 to slide is formed on the locking disk 6. A locking elastic member for pushing the locking columns 61 to slide outwards of the placement groove 62 is provided on the locking disk 6. In the embodiment of the present application, the locking elastic member is a locking spring 621. One end of the locking spring 621 is fixed to the inner wall of the placement groove 62, and the other end of the locking spring 621 is fixed to the locking column 61. After the locking disk 6 slides, the locking columns 61 in the inner circle are embedded in the inner circle groove 521, and the locking columns 61 in the outer circle are received in the placement groove 62, or the locking columns 61 in the outer circle are embedded in the outer circle groove 522, and the locking columns 61 in the inner circle are embedded in the placement groove 62.

A positioning chute 71 for the positioning column 7 to slide is formed in the main bracket 1. The positioning chute 71 communicates with the rotation groove 51. Sixteen positioning grooves 72 for the positioning column 7 to be embedded after sliding are formed on the outer peripheral wall of the rotating disk 5. The sixteen positioning grooves 72 are arranged in a circumferential array with the axis of the locking disk 6 as the center. When the positioning column 7 is embedded in any one of the positioning grooves 72, the locking columns 61 in the outer circle correspond to the outer circle groove 522 or the locking columns 61 in the inner circle correspond to the inner circle groove 521, which facilitates the locking columns 61 to be embedded in the locking groove 52 after the locking disk 6 slides. The end of the locking column 61 away from the locking groove 52 is spherical, which provides guidance for the locking column 61 to be embedded in the locking groove 52 and improves the reliability of locking the rotation of the rotating disk 5 through the cooperation of the locking column 61 and the locking groove 52.

[0056] Refer to Figure 7 and Figure 8 , the adjacent inner walls of the positioning grooves 72 are inclined, and the end of the positioning column 7 is adapted to the positioning grooves 72, so as to facilitate the positioning column 7 to slide in the positioning grooves 72. A positioning elastic member for pushing the positioning column 7 to slide outwards of the positioning chute 71 is provided on the main bracket 1. In the embodiment of the present application, the positioning elastic member is a positioning spring 711. One end of the positioning spring 711 is fixed to the inner wall of the positioning chute 71, and the other end of the positioning spring 711 is fixed to the positioning column 7. Through the arrangement of the positioning spring 711, the positioning column 7 can be completely embedded in the corresponding positioning groove 72.

[0057] Refer to Figure 6 and Figure 9, three guide posts 63 are fixedly connected to the locking plate 6. The guide posts 63 are slidably connected to the main bracket 1 and slide perpendicularly to the length direction of the main bracket 1. Guide grooves 631 for the guide posts 63 to slide are formed on the inner wall of the storage cavity 14. With the cooperation of the guide posts 63 and the guide grooves 631, the locking plate 6 is not prone to rotate relative to the main bracket 1; a reset elastic member for pushing the guide posts 63 to slide outwards of the guide grooves 631 is provided on the main bracket 1. In the embodiment of the present application, the reset elastic member is a reset spring 632. One end of the reset spring 632 is fixed to the inner wall of the guide groove 631, and the other end of the reset spring 632 is fixed to the guide post 63. Through the setting of the reset elastic member, without the action of other external forces, the locking plate 6 can slide away from the rotating disc 5, thereby releasing the locking of the rotation of the rotating disc 5.

[0058] Referring to Figure 6 and Figure 8 , a fitting for driving the locking plate 6 to slide is provided on the main bracket 1. The fitting includes a driving block 64 provided at one end of the locking plate 6 facing away from the rotating disc 5. A driving groove 312 is formed on the outer wall of the sliding portion 31. The driving block 64 is slidably arranged in the driving groove 312. The inner wall of the driving groove 312 is provided with an inclined surface 313. The distance between the highest point of the inclined surface 313 and the inner wall of the storage cavity 14 is less than the distance between the lowest point of the inclined surface 313 and the inner wall of the storage cavity 14. The driving block 64 has the same shape as the driving groove 312; when the earth-breaking cone 3 is completely stored in the storage cavity 14, the driving block 64 is completely located in the driving groove 312 and fits with the inner wall of the driving groove 312. When the earth-breaking cone 3 slides outwards of the storage cavity 14, the driving block 64 slides along the inclined surface 313, and the locking plate 6 slides towards the rotating disc 5 under the cooperation of the driving block 64 and the driving groove 312.

[0059] The implementation principle of a formwork support that is easy to disassemble and assemble in the embodiment of the present application is as follows: By lifting the handle 133 to drive the fixing plate 12 to slide away from the fitting groove 11, when the connecting rod 21 is inserted into the main bracket 1 containing the rotating disc 5, the telescopic rod 22 is inserted into another main bracket 1, and the mounting block 111 is inserted into the mounting groove 24, release the handle 133. At this time, the fixing plate 12 is inserted into the fixing groove 23 to complete the installation of the formwork support.

[0060] According to the needs of construction, the connecting rod 21 is rotated to control the distance between the connecting rod 21 and the telescopic rod 22. At the same time, the main bracket 1 fixed with the telescopic rod 22 is manually controlled to make the two main brackets 1 always in a parallel state. After the adjustment is completed, the surrounding purlin bracket is moved to the installation point, and the control block 4 is driven to slide toward the ground by stepping on the second block 42 located outside the main bracket 1. With the cooperation of the rotating gear 163 and the rotating rack 411, the control block 4 slides to be embedded in the ground, which enables the closing plate 16 to rotate to release the closure of the storage cavity 14, and the initial positioning of the surrounding purlin bracket is completed while the storage cavity 14 is opened.

[0061] Finally, the rotating block 15 is driven to rotate by a rotating motor with a block equipped at the construction site. When the rotating block 15 rotates, it can synchronously drive the screw 151 and the control rod 152 to rotate. When the screw 151 rotates, the sliding part 31 slides in the storage chamber 14. When the control rod 152 rotates, the driving rod 153 drives the ground-breaking part 32 to rotate, so that the ground-breaking part 32 is embedded in the soil, completing the installation of the purlin bracket; in this process, the locking disk 6 slides toward the rotating disk 5 under the cooperation of the driving block 64 and the driving groove 312, and the inner ring locking column 61 is embedded in the inner ring groove 521, and the outer ring locking column 61 is stored in the placement groove 62, or the outer ring locking column 61 is embedded in the outer ring groove 522, and the inner ring locking column 61 is embedded in the placement groove 62.

[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
