Description

Technical Field

[0001] The invention relates to the technical field of steel column moulds, and in particular to a modular steel column external cast concrete mould. Background Art

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] In building structural engineering, steel column cast-in-place concrete composite structures are widely used in super high-rise buildings, large-span bridges and heavy industrial plants because they combine the high strength of steel and the compressive properties of concrete.

[0004] During production, a combined formwork is usually used to surround the steel column, and then concrete is poured into the surrounding area to expel excess bubbles in the concrete. A vibration pump is used to vibrate and compact the concrete. After solidification, a casting layer can be formed on the outer surface of the steel column. The required steel column cast-in-place concrete composite structure can then be removed from the formwork.

[0005] Since the existing composite formwork is mostly fixed by bolts, the formwork is inconvenient to disassemble and assemble when assembling the formwork or demoulding the material, which is time-consuming and labor-intensive, affecting the production progress of the steel column cast-in-place concrete composite structure. Summary of the Invention

[0006] The main purpose of the present invention is to provide a modular steel column external cast concrete mold.

[0007] To achieve the above objectives, the technical solution of the present invention is implemented as follows: a modular steel column external pouring concrete mold, which is used to pour concrete on the outer surface of a steel column with a rectangular longitudinal section to form a pouring layer, the mold comprising a matching top plate, a bottom plate, two side plates and two end plates;

[0008] The top plate and bottom plate are located at the top and bottom sides of the steel column in the length direction respectively; the two side plates are located at the two sides of the steel column in the length direction respectively; the two end plates are located at the two ends of the steel column in the length direction respectively;

[0009] The top plate is provided with grouting holes for concrete injection;

[0010] The top plate, the bottom plate, the two side plates and the two end plates enclose a pouring space for pouring concrete on the outer surface of the steel column;

[0011] The modular steel column cast-in-place concrete mold further includes a positioning device, which is used to lock the relative positions of the top plate, the bottom plate, the two side plates and the two end plates after they are enclosed.

[0012] The beneficial effects of the present invention are embodied in:

[0013] 1. The modular steel column external cast concrete mold of the present invention breaks the original idea. After the templates are initially enclosed on the outside of the steel column, the relative positions of the templates can be conveniently and efficiently locked and fixed synchronously through the positioning device, ensuring the production progress of the steel column external cast concrete composite structure.

[0014] 2. The modular steel column cast-in-place concrete mold of the present invention is assembled by first assembling the side panels, bottom panel, top panel and both side end panels in sequence, and then using the first locking assembly to fix the top panel to the top of the two side panels and the bottom panel to the bottom of the two side panels. At the same time, the second locking assembly squeezes the two end panels toward the end sides where the corresponding side panels, top panel and bottom panel are located, so as to fix the two end panels to the corresponding side panels, top panel and bottom panel stably and reliably.

[0015] 3. The modular steel column cast-in-place concrete mold of the present invention has two driving motors that are staggered in different planes. Therefore, when the two driving motors respectively drive their respective second rotating drums to rotate, not only the top plate and the bottom plate are respectively pressed and fixed between the top and bottom of the two side plates, but also the screws on the end plates can be driven to rotate synchronously. Under the limiting action of the sliding rod, the synchronous blocks on the screws can be moved along the axial direction of the screws, and then the synchronous blocks can drive the inclined blocks on the end plates to enter the corresponding inclined grooves through the second connecting rod, forcing the inclined blocks to apply an extrusion force toward the side plates, top plates and bottom plates on the side facing the end plates, so that the two end plates are respectively crimped and fixed on the two end sides of the side plates, top plates and bottom plates, and are easy to disassemble.

[0016] 4. The modular steel column cast-in-place concrete mold of the present invention can, by providing the first receiving groove, insert block, etc., on the one hand, prevent the oblique blocks on the top plate and the bottom plate from excessively squeezing the oblique grooves and causing damage; on the other hand, it can release the synchronous movement state between some oblique blocks that have squeezed and tightened the oblique grooves and the transmission rods, avoiding interference with the transmission rod driving the synchronous movement of the remaining oblique blocks that have not been inserted into and tightened with the corresponding oblique grooves, thereby ensuring the effective tightening rate between the oblique blocks and the oblique grooves on the top plate and the bottom plate, and further ensuring the stability of the crimping of the top plate and the bottom plate on the two side plates.

[0017] 5. The modular steel column cast-in-place concrete mold of the present invention can, by providing the second receiving groove, tooth plate, etc., on the one hand, prevent the oblique blocks on the end plates from excessively squeezing the oblique grooves and causing damage; on the other hand, it can release the screw-engaged transmission state between some oblique blocks that have squeezed and tightened the oblique grooves and the screw rods, thereby avoiding interference with the screw-engaged drive of the remaining oblique blocks that have not been inserted into and tightened with the corresponding oblique grooves, thereby ensuring the effective tightening rate between the oblique blocks on the end plates and the oblique grooves, and further ensuring the stability of the two end plates pressed on the two side plates.

DETAILED DESCRIPTION

[0041] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Obviously, the embodiments described are only some embodiments of the invention, not all embodiments. In the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the invention.

[0042] Please combine Figures 1 to 20 .

[0043] A modular steel column external cast concrete mold is used for pouring concrete on the outer surface of a steel column 100 with a rectangular longitudinal section to form a pouring layer 103. The mold includes a matching top plate 2, a bottom plate 3, two side plates 1 and two end plates 4.

[0044] The top plate 2 and bottom plate 3 are respectively located at the top and bottom sides of the steel column 100 in the longitudinal direction. The two side plates 1 are respectively located at the two sides of the steel column 100 in the longitudinal direction. The two end plates 4 are respectively located at the two ends of the steel column 100 in the longitudinal direction.

[0045] The top plate 2 is provided with grouting holes 7 for injecting concrete.

[0046] The top plate 2 , the bottom plate 3 , the two side plates 1 and the two end plates 4 enclose a pouring space for pouring concrete on the outer surface of the steel column 100 .

[0047] The modular steel column cast-in-place concrete mold further includes a positioning device, which is used to lock the relative positions of the top plate 2, the bottom plate 3, the two side plates 1 and the two end plates 4 after they are enclosed.

[0048] In a specific embodiment, the two side panels 1, bottom panel 3, top panel 2, and two end panels 4 are sequentially hoisted and installed in corresponding positions on the steel column 100. A positioning device is used to lock the relative positions of the top panel 2, bottom panel 3, two side panels 1, and two end panels 4 after enclosure. A vibration pump (not shown) is installed in the corresponding position of the side panel 1. Concrete is delivered to the casting space through the grouting holes 7. The vibration pump is used to evenly distribute and compact the concrete in the casting space, expel excess bubbles, and form a casting layer 103 on the surface of the steel column 100 after solidification. Demolding is achieved by reversing the positioning device to obtain the steel column 100 with the external casting layer 103.

[0049] The advantage of this design is that it breaks the traditional method of fixing the templates with bolts, and instead uses a positioning device to conveniently and efficiently realize the assembly and disassembly of the templates, greatly improving the production efficiency of the cast-in-place column 100 and saving time and effort.

[0050] It should be noted that the side plate 1 in the present application is a U-shaped channel steel.

[0051] In one embodiment, the positioning device includes two sets of first locking assemblies and two sets of second locking assemblies.

[0052] The top and bottom of the side plate 1 are provided with a plurality of positioning columns 9 parallel to the height direction of the steel column 100 at equal intervals along the length direction of the steel column 100 .

[0053] Both ends of the side plate 1 have a plurality of positioning columns 9 along the height direction of the steel column 100 and parallel to the length direction of the steel column 100.

[0054] Both ends of the top plate 2 and the bottom plate 3 are provided with a plurality of positioning columns 9 along the width direction of the steel column 100 and parallel to the length direction of the steel column 100 .

[0055] The top plate 2 is provided with a positioning hole 10 for the positioning column 9 on the top of the side plate 1 to pass through.

[0056] The bottom plate 3 is provided with a positioning hole 10 for the positioning column 9 at the bottom of the side plate 1 to pass through.

[0057] The end plate 4 is provided with positioning holes 10 for the positioning posts 9 located at the end sides of the side plates 1 , the top plate 2 and the bottom plate 3 to pass through.

[0058] The two sets of first locking assemblies are respectively arranged on the top plate 2 and the bottom plate 3. When the positioning columns 9 at the top and bottom of the side plate 1 pass through the corresponding positioning holes 10 on the top plate 2 and the bottom plate 3 respectively, the two sets of first locking assemblies are respectively used to squeeze the top plate 2 and the bottom plate 3 toward the corresponding top and bottom of the side plate 1.

[0059] The two sets of second locking assemblies are respectively arranged on the two end plates 4. When the positioning columns 9 located at the end sides of the side plates 1, the top plate 2 and the bottom plate 3 pass through the corresponding positioning holes 10 on the end plates 4, and when the top plate 2 and the bottom plate 3 are respectively squeezed toward the top and bottom of the corresponding side plates 1, the two sets of second locking assemblies are respectively used to squeeze the two end plates 4 toward the end sides of the corresponding side plates 1, the top plate 2 and the bottom plate 3.

[0060] In this way, during assembly, the two side panels 1 are first hoisted on both sides of the steel column 100 in the length direction to ensure that the first through-hole 5 and the second through-hole 6 on the side panel 1 can respectively allow the steel section 101 and the stiffening plate 102 on the steel column 100 to pass through.

[0061] Then, the bottom plate 3 and the top plate 2 are hoisted and installed on the bottom and top of the steel column 100 respectively, ensuring that the first through-hole 5 on the bottom plate 3 and the grouting hole 7 on the top plate 2 can respectively allow the steel section 101 on the steel column 100 to pass through, and ensuring that the positioning columns 9 at the bottom of the side plate 1 can all pass through the positioning holes 10 at the bottom of the bottom plate 3 and ensuring that the positioning columns 9 at the top of the side plate 1 can all pass through the positioning holes 10 at the top of the top plate 2, so as to realize the assembly between the side plates 1, the top plate 2 and the bottom plate 3.

[0062] Then, the two end plates 4 are hoisted at both ends of the steel column 100 respectively, so that the positioning columns 9 on the same side of the side plate 1, top plate 2 and bottom plate 3 can all pass through the positioning holes 10 on the end plate 4, thereby completing the assembly of the side plate 1, top plate 2, bottom plate 3 and end plate 4 to form a mold, so that a casting space is formed inside the mold.

[0063] Finally, by utilizing two sets of first locking assemblies, the two sets of first locking assemblies squeeze the top plate 2 and the bottom plate 3 toward the top and bottom of the corresponding side plates 1, respectively, so as to achieve the fixation of the top plate 2 on the top of the two side plates 1 and the fixation of the bottom plate 3 on the bottom of the two side plates 1, and the two sets of second locking assemblies can be simultaneously utilized to squeeze the two end plates 4 toward the end sides where the corresponding side plates 1, top plates 2 and bottom plates 3 are located, so as to achieve the fixation of the two end plates 4 on the side plates 1, top plates 2 and bottom plates 3 on the corresponding sides.

[0064] In one embodiment, the first locking assembly includes two transmission rods 13 that are arranged opposite to each other along the width direction of the steel column 100 and parallel to the length direction of the steel column 100. Both transmission rods 13 can be movably arranged at the top of the top plate 2 or the bottom of the bottom plate 3 along the length direction of the steel column 100.

[0065] In the present application, the two sets of first locking assemblies are respectively located at the top of the top plate 2 and the bottom of the bottom plate 3 , that is, the top of the top plate 2 and the bottom of the bottom plate 3 each have two transmission rods 13 .

[0066] A plurality of synchronous sleeves 14 are axially arranged on the outside of the transmission rod 13 and are synchronized with its movement. The outside of each synchronous sleeve 14 is connected to an inclined block 16 through a first connecting rod 15. The outside of the synchronous sleeve 14 is fixedly connected to one end of the first connecting rod 15, and the other end of the first connecting rod 15 is fixedly connected to the inclined block 16.

[0067] It should be noted that the inclined surface of the inclined block 16 on the top plate 2 is located on the top side thereof, and the inclined surface of the inclined block 16 on the bottom plate 3 is located on the bottom side thereof.

[0068] The positioning columns 9 at the top and bottom of the side panel 1 are both provided with inclined grooves 17 that cooperate with the inclined block 16. By driving the transmission rod 13 to move in the length direction of the steel column 100, the inclined block 16 is indirectly driven to enter and squeeze the inclined groove 17, forcing the inclined block 16 to face the side of the top plate 2 or the bottom plate 3 to apply an extrusion force toward the top plate 2 or the bottom plate 3 toward the side panel 1.

[0069] In this way, when the transmission rod 13 on the top plate 2 or the bottom plate 3 is driven to move, so that the corresponding inclined block 16 moves toward the corresponding inclined groove 17, the transmission rod 13 can drive the synchronous sleeve 14 thereon to move synchronously, and the synchronous sleeve 14 drives the corresponding inclined block 16 to enter and squeeze the corresponding inclined groove 17 through the first connecting rod 15, so that the inclined block 16 is subjected to the reverse action from the inclined groove 17, forcing the inclined block 16 to face the side of the top plate 2 or the bottom plate 3 to apply an extrusion force toward the top plate 2 or the bottom plate 3 toward the side plate 1, thereby completing the compression and fixation of the top plate 2 and the bottom plate 3 on the top and bottom of the side plate 1.

[0070] In one embodiment, first vertical panels 11 are fixed to the tops of both ends of the top panel 2. Second vertical panels 111 are fixed to the bottoms of both ends of the bottom panel 3. The first vertical panels 11 and the second vertical panels 111 have the same structure.

[0071] One end of the transmission rod 13 is slidably inserted into one of the first vertical plates 11 or the second vertical plates 111 .

[0072] In the present application, one end of the two transmission rods 13 on the top plate 2 is slidably inserted on the same first vertical plate 11 , and one end of the two transmission rods 13 on the bottom plate 3 is slidably inserted on the same second vertical plate 111 .

[0073] It should be noted that the first vertical plate 11, into which the transmission rod 13 is slidably inserted, and the second vertical plate 111, into which the transmission rod 13 is slidably inserted, are arranged in a skewed arrangement. This allows the top plate 2 to be firmly secured against the tops of the two side plates 1 when the transmission rod 13 on the top plate 2 drives the corresponding inclined blocks 16 into the corresponding inclined slots 17. Furthermore, the bottom plate 3 can be firmly secured against the bottoms of the two side plates 1 when the transmission rod 13 on the bottom plate 3 drives the corresponding inclined blocks 16 into the corresponding inclined slots 17.

[0074] The two sets of first locking assemblies are respectively located at the top of the top plate 2 and the bottom of the bottom plate 3 , that is, the top of the top plate 2 and the bottom of the bottom plate 3 each have two transmission rods 13 .

[0075] The top of the top plate 2 and the bottom of the bottom plate 3 are both provided with a first support block 31. The other end of each transmission rod 13 is slidably inserted into the corresponding first support block 31.

[0076] Two first rotating drums 24 are provided on one of the first vertical plates 11 and one of the second vertical plates 111 for relative rotation. The first rotating drums 24 are located on a side away from the corresponding first supporting block 31 .

[0077] The transmission rod 13 is provided with a limit block 22 extending into the inner side of the corresponding first rotating drum 24 at one end close to the corresponding first vertical plate 11 or second vertical plate 111, that is, the limit block 22 is fixed on the end of the transmission rod 13 on the top plate 2 away from the first support block 31, and the limit block 22 is fixed on the end of the transmission rod 13 on the bottom plate 3 away from the first support block 31.

[0078] The longitudinal section of the limiting block 22 is a quarter semicircular structure.

[0079] A protrusion 25 is fixed on the inner side of the first rotating drum 24 , and the limiting block 22 is respectively provided with a first groove 221 and a second groove 222 which are plugged and synchronously matched with the protrusion 25 on the front and rear sides of the first rotating drum 24 in the rotation direction.

[0080] Two second rotating cylinders 26 are rotatably provided on the corresponding first vertical plate 11 and the second vertical plate 111 and can be threadedly engaged with the corresponding first rotating cylinder 24 after being inserted.

[0081] By driving the second rotating drum 26 to rotate, the second rotating drum 26 drives the first rotating drum 24 to rotate synchronously through friction, so that the protrusion 25 of the first rotating drum 24 is inserted into the first groove 221 to form a moving whole with the transmission rod 13, and the second rotating drum 26 is continued to be driven to rotate to cooperate with the thread between the first rotating drum 24, so that the first rotating drum 24 drives the transmission rod 13 to move along the length direction of the steel column 100.

[0082] In this way, when the second rotating drum 26 is driven to rotate, the second rotating drum 26 can first drive the first rotating drum 24 to rotate synchronously through friction, so that the protrusion 25 of the first rotating drum 24 is inserted into the first groove 221 to form a moving whole with the limit block 22 and the transmission rod 13, and continue to drive the second rotating drum 26 to rotate to cooperate with the thread between the first rotating drum 24, so that the first rotating drum 24 drives the transmission rod 13 to move along the length direction of the steel column 100, and then drives the synchronous sleeve 14 and the first connecting rod 15 to make the corresponding inclined block 16 enter, locking the relative position of the corresponding positioning column 9 in the positioning hole 10.

[0083] When it is necessary to release the extrusion state between the inclined block 16 and the inclined groove 17, it is only necessary to drive the second rotating drum 26 to rotate in the opposite direction. The second rotating drum 26 can first drive the first rotating drum 24 to rotate synchronously through friction, so that the protrusion 25 on the first cylinder 24 disengages from the first groove 221 and then enters the second groove 222 to form a moving whole with the transmission rod 13, and continue to drive the second rotating drum 26 to rotate in the opposite direction to cooperate with the thread between the first rotating drum 24, so that the first rotating drum 24 drives the transmission rod 13 to move in the opposite direction along the length direction of the steel column 100, and then drives the synchronous sleeve 14 and the first connecting rod 15 to make the corresponding inclined block 16 disengage from the corresponding inclined groove 17, thereby releasing the extrusion state between the inclined block 16 and the inclined groove 17, and releasing the position lock of the corresponding positioning column 9 in the positioning hole 10.

[0084] In one embodiment, a drive motor 29 is installed on each of the corresponding first vertical plate 11 and second vertical plate 111. The two drive motors 29 are arranged in an eccentric and staggered manner. The output shaft of the drive motor 29 is connected to a driving gear 30, and a driven gear 35 that cooperates with the corresponding driving gear 30 is fixed on the outer side of one of the corresponding second rotating drums 26.

[0085] Thus, when the drive motor 29 on the top plate 2 rotates, the corresponding second rotating drum 26 can be driven to rotate via the driving gear 30 and the driven gear 35, thereby achieving compression and fixation of the top plate 2 on the top of the side plate 1 or release of the compression. When the drive motor 29 on the bottom plate 3 rotates, the corresponding second rotating drum 26 can be driven to rotate via the driving gear 30 and the driven gear 35, thereby achieving compression and fixation of the bottom plate 3 on the bottom of the side plate 1 or release of the compression.

[0086] In one embodiment, the second locking assembly includes four screws 18 that are rectangularly arranged on the end plate 4 and can rotate. The two horizontal screws 18 located on the top and bottom sides are fixed with third bevel teeth 33 at both axial ends, and the two vertical screws 18 located on both sides are fixed with fourth bevel teeth 34 that cooperate with the corresponding third bevel teeth 33 at both axial ends.

[0087] A synchronization block 20 is sleeved on the outside of each screw rod 18. The outer wall of the synchronization block 20 near the positioning hole 10 is connected to the inclined block 16 via a second connecting rod 21. The positioning columns 9 at the side ends of the side panels 1, top panel 2, and bottom panel 3 are all provided with inclined slots 17 that cooperate with the inclined blocks 16. A sliding rod 19 is spaced apart and parallel to the side of the screw rod 18 away from the positioning hole 10, and the synchronization block 20 is slidably sleeved on the sliding rod 19.

[0088] A first bevel gear 27 is fixed to the outer side of the second rotating cylinder 26 , and second bevel gears 28 that match the corresponding first bevel gears 27 are provided at both ends of the screw 18 located on the upper side or the lower side.

[0089] The inclined block 16 on the synchronization block 20 is indirectly driven by the second rotating drum 26, so that the inclined block 16 enters and squeezes the inclined groove 17, forcing the inclined block 16 to apply an extrusion force on the end plate 4 toward the side plate 1, the top plate 2 and the bottom plate 3.

[0090] It should be pointed out that:

[0091] On the end plate 4 on the side where the drive motor 29 is located on the top plate 2: second bevel teeth 28 are fixed at both ends of the screw 18 on the top side, and first bevel teeth 27 are fixed on the two second rotating cylinders 26 on the end plate 4. The two first bevel teeth 27 are respectively matched with the two second bevel teeth 28. When the drive motor 29 on the top plate 2 drives the second rotating cylinder 26 to rotate, the other second rotating cylinder 26 on the end plate 4 can be synchronously driven to rotate synchronously, so as to realize the synchronous movement of the two transmission rods 13 on the top plate 2, and thereby realize the synchronous tightening or compression release of the top plate 2 between the tops of the two side plates 1.

[0092] On the end plate 4 on the side where the drive motor 29 is located on the bottom plate 3: second bevel teeth 28 are fixed at both ends of the screw 18 on the bottom side, and first bevel teeth 27 are fixed on the two second rotating cylinders 26 on the end plate 4. The two first bevel teeth 27 are respectively matched with the two second bevel teeth 28. When the drive motor 29 on the bottom plate 3 drives the second rotating cylinder 26 to rotate, the other second rotating cylinder 26 on the end plate 4 can be synchronously driven to rotate synchronously, so as to realize the synchronous movement of the two transmission rods 13 on the bottom plate 3, and thereby realize the synchronous tightening or compression release of the bottom plate 3 between the bottoms of the two side plates 1.

[0093] In this way, when the two driving motors 29 respectively drive their respective second rotating drums 26 to rotate, not only the top plate 2 and the bottom plate 3 are respectively pressed and fixed between the top and bottom of the two side plates 1, but also the screws 18 on the end plates 4 can be synchronously driven to rotate synchronously, and under the limiting action of the slide bar 19, the synchronization blocks 20 on the screw 18 can be moved along the axial direction of the screw 18, and then the synchronization block 20 can drive the inclined block 16 on the end plate 4 to enter the corresponding inclined groove 17 through the second connecting rod 21, forcing the inclined block 16 to apply an extrusion force to the end plate 4 toward the side of the end plate 4 toward the side plate 1, top plate 2 and bottom plate 3, so that the two end plates 4 are respectively crimped and fixed on the two end sides of the side plate 1, top plate 2 and bottom plate 3, and are easy to disassemble.

[0094] In one embodiment, multiple groups of second support blocks 32 are fixed on the end plate 4. Each group includes two second support blocks 32, and the two second support blocks 32 are used to insert the same screw rod 18 and the same sliding rod 19.

[0095] In this way, a rectangular arrangement of the screw rods 18 and the sliding rods 19 on the end plate 4 can be achieved.

[0096] In one embodiment, a first receiving groove 40 is radially defined on the inner side of the synchronization sleeve 14. An insert block 37 is elastically disposed in the first receiving groove 40 by a first spring, protruding from the groove opening. A plurality of slots 36 are axially defined on the outer side of the transmission rod 13 for receiving the insert blocks 37. The sidewalls of the slots 36 have a predetermined slope.

[0097] When the inserting block 37 on the top plate 2 or the bottom plate 3 is inserted into the corresponding slot 36 , the synchronizing sleeve 14 moves synchronously with the transmission rod 13 .

[0098] When the inclined block 16 on the top plate 2 or the bottom plate 3 completely enters the corresponding inclined groove 17, if the transmission rod 13 continues to move toward the inclined groove 17, the bottom of the inclined block 16 is forced to slide along the predetermined slope to disengage from the slot of the corresponding slot 36, and the top of the inclined block 16 is received into the first receiving groove 40, the first spring is compressed, and the movement synchronization state between the synchronization sleeve 14 and the transmission rod 13 is released.

[0099] It should be noted that the predetermined slope angle of the slot 36 can be seventy-five degrees. In this way, when the insert block 37 on the top plate 2 or the bottom plate 3 is inserted into the corresponding slot 36, the synchronization sleeve 14 and the transmission rod 13 move synchronously.

[0100] When the inclined block 16 on the top plate 2 or the bottom plate 3 completely enters the corresponding inclined groove 17, if the transmission rod 13 continues to move toward the inclined groove 17 (the inclined block 16 can no longer move synchronously with the transmission rod 13), the bottom of the inclined block 16 will be forced to slide along the predetermined slope to disengage from the slot of the corresponding slot 36, and the top of the inclined block 16 will be received into the first receiving groove 40. The first spring is compressed to release the movement synchronization state between the synchronization sleeve 14 and the transmission rod 13, thereby preventing the inclined block 16 from interfering with the movement of the transmission rod 13. Subsequently, the bottom of the inclined block 16 can enter the next slot 36 in the moving direction of the transmission rod 13 under the action of the elastic force of the first spring.

[0101] In this way, on the one hand, the inclined blocks 16 on the top plate 2 and the bottom plate 3 can be prevented from excessively squeezing and damaging the inclined grooves 17; on the other hand, the synchronous movement state between some of the inclined blocks 16 that have squeezed and tightened the inclined grooves 17 and the transmission rods 13 can be released, avoiding interference with the transmission rods 13 driving the synchronous movement of the remaining inclined blocks 16 that have not been stretched into and tightened with the corresponding inclined grooves 17, thereby ensuring the effective tightening rate between the inclined blocks 16 and the inclined grooves 17 on the top plate 2 and the bottom plate 3, and further ensuring the stability of the crimping of the top plate 2 and the bottom plate 3 on the two side plates 1.

[0102] In addition, after demoulding and taking out the material, the synchronous sleeves 14 and the corresponding inclined blocks 16 on the transmission rod 13 can be adjusted to return to the corresponding positions on the transmission rod 13 to ensure that the inclined blocks 16 on the transmission rod 13 can be pressed and synchronized as much as possible when used next time.

[0103] In one embodiment, the synchronization block 20 has a through hole (not marked) for the screw 18 to pass through, and a second receiving groove 41 is radially opened on the inner side of the through hole. The second receiving groove 41 is connected to the third connecting rod 38 through a second spring, and one end of the third connecting rod 38 is provided with a tooth plate 39 that cooperates with the thread of the screw 18.

[0104] When the internal thread of the tooth plate 39 is engaged with the external thread of the screw rod 18 , the screw rod 18 rotates to cause the synchronizer block 20 to move axially along the screw rod 18 .

[0105] When the inclined block 16 on the end plate 4 completely enters the corresponding inclined groove 17, if the screw 18 continues to rotate to make the corresponding inclined block 16 continue to move toward the corresponding inclined groove 17, the internal thread of the tooth plate 39 is forced to centrifugally disengage from the external thread of the screw 18, causing the third connecting rod 38 to move into the second receiving groove 41, and the second spring is compressed to release the meshing transmission state between the tooth plate 39 and the screw 18.

[0106] In this way, when the internal thread of the tooth plate 39 is engaged with the external thread of the screw rod 18 , the screw rod 18 rotates to cause the synchronizer block 20 to move axially along the screw rod 18 .

[0107] When the inclined block 16 on the end plate 4 completely enters the corresponding inclined groove 17, if the screw 18 continues to rotate (the synchronous block 20 can no longer continue to drive the inclined block 16 to move into the inclined groove 17 under the screw driving action of the screw 18), the tooth plate 39 will be under the reaction force of the inclined groove 17, so that the internal thread of the tooth plate 39 will be centrifugally disengaged from the external thread of the screw 18, causing the third connecting rod 38 to move into the second receiving groove 41, and the second spring will be compressed, releasing the threaded engagement transmission state between the synchronous block 20 and the transmission rod 13, thereby preventing the inclined block 16 from interfering with the rotation of the screw 18.

[0108] In this way, on the one hand, the over-extrusion and damage of the inclined groove 17 by the inclined block 16 on the end plate 4 can be avoided; on the other hand, the screw-engaged transmission state between some of the inclined blocks 16 that have squeezed and tightened the inclined groove 17 and the screw 18 can be released, thereby avoiding interference with the screw 18's screw-engaged drive of the remaining inclined blocks 16 that have not been inserted into and tightened with the corresponding inclined groove 17, thereby ensuring the effective tightening rate between the inclined block 16 and the inclined groove 17 on the end plate 4, and further ensuring the stability of the two end plates 4 pressed on the two side plates 1.

[0109] In addition, after demoulding and taking out the material, the synchronization blocks 20 and the corresponding inclined blocks 16 on the screw 18 can be adjusted to return to the corresponding positions on the screw 18 to ensure that the inclined blocks 16 on the screw 18 can be tightened and synchronized as much as possible when used next time.

[0110] In one embodiment, steel sections 101 are provided at the top, bottom and both sides of the steel column 100, and the side panels 1 and the bottom panel 3 are both provided with first through-holes 5 for the steel sections 101 to penetrate for positioning. The steel sections 101 at the top of the steel column 100 are positioned by penetrating grouting holes 7.

[0111] Stiffening plates 102 corresponding to the positions of the corresponding steel sections 101 are provided on both sides of the steel column 100 , and second through holes 6 for the stiffening plates 102 to penetrate and position are opened on the side plate 1 .

[0112] The end plate 4 is provided with a third through-hole 8 for the end of the steel column 100 to pass through and extend to the outside of the casting space.

[0113] It should be noted that the steel section 101 in this application is an H-shaped steel, and the steel section 101 and the stiffening plate 102 can be mounted on the steel column 100 by welding. Before pouring, it is necessary to apply a caulking agent between the third through-hole 8 and the outer end face of the steel column 100 to prevent concrete from flowing out of the third through-hole 8 during grouting.

[0114] In this way, the steel section 101 and the stiffening plate 102 can facilitate the installation and positioning of the steel column 100 after external pouring.
