Description

Technical Field

[0001] The invention relates to the field of concrete steel column production, and in particular to a steel formwork assembly gap sealing mechanism. Background Art

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

[0003] During the production process of concrete steel columns, prefabricated steel molds need to be assembled to form a model with a certain spatial structure, and then concrete is filled in the internal space to form a prefabricated concrete steel column. When the steel mold is assembled, since the side of the steel mold has a steel section extending outward, a perforation for the steel section to pass through must be reserved at this location. In order to facilitate the insertion of the steel section, the internal size of the perforation is usually slightly larger than the external size of the steel section. After the steel mold is assembled, a joint is formed between the hole wall of the perforation and the steel section. After the steel mold is fully assembled, the joint needs to be sealed to prevent concrete from leaking from the joint during subsequent concrete pouring. Existing joint sealing is usually done manually using sealing glue. Due to the large area of ​​the steel mold, it is impossible to ensure that the sealing glue is evenly applied to each gap. If too much sealing glue is applied, the internal concrete will be sunken. If too little sealing glue is applied, the model may be uneven or overflowing. Traditional glue injection devices cannot effectively control this problem, which in turn affects the quality of concrete and production costs. Summary of the Invention

[0004] The main purpose of the present invention is to provide a sealing mechanism for steel mold assembly gaps.

[0005] To achieve the above-mentioned purpose, the technical solution of the present invention is implemented as follows: a steel mold assembly gap sealing mechanism includes a feeding pipe for feeding, one side of the feeding pipe is connected to an embedded tube for side glue discharge, the bottom end of the embedded tube is connected to an execution tube for bottom glue discharge, the embedded tube and the execution tube can be extended into the splicing seam, and a diversion component is also provided between the embedded tube and the execution tube. The diversion component controls the glue discharge from the embedded tube or the execution tube. The bottom of the execution tube is also connected to a limiting component, which is used to assist in limiting the depth of the embedded tube extending into the splicing seam.

[0006] Furthermore, a transfer tube is connected through the embedded tube, one end of the transfer tube is connected to the feed tube, and the other end of the transfer tube is connected to the diversion component.

[0007] Furthermore, the flow diversion assembly includes a control chamber located in the actuator tube, a flow diversion sleeve rotatably connected to the transfer tube in the control chamber, two sets of serial holes 2 are respectively provided on the upper and lower sides of the flow diversion sleeve, and serial holes 1 and 3 are respectively provided on the upper and lower sides of the control chamber; Furthermore, the serial hole one is connected to the embedded tube, the serial hole three is connected to the bottom of the actuator tube, the serial hole one and the serial hole three are located on the rotation trajectory of the serial hole two, and the rotating diverter sleeve can align and connect the corresponding serial hole two with the serial hole one and the serial hole three in turn, and the serial hole two is connected to the serial hole one, so that the diverter sleeve is connected to the embedded tube, and the serial hole two and the serial hole three are docked, so that the diverter sleeve is connected to the bottom of the actuator tube.

[0008] Furthermore, the limiting assembly includes a rotating shaft rotatably connected to the actuator tube through a torsion spring, and an expansion plate embedded in the outer side of the actuator tube is commonly fixed at both ends of the rotating shaft. A swing rod is also rotatably provided on one side of the rotating shaft through a spring hinge, and the other end of the swing rod is rotatably connected to a push rod, and the other end of the push rod is fixed to a limiting frame, and a rubber block in sliding contact with the actuator tube is fixedly connected to the outer side of the limiting frame. During the rotation of the rotating shaft, the swing rod is driven to move obliquely, and after the end of the swing rod in contact with the rotating shaft hits the bottom of the actuator tube, the expansion plate reaches the maximum expansion angle, and at the same time, the spring hinge on the rotating shaft is in a stressed state, and the end of the swing rod in contact with the actuator tube away from the rotating shaft moves linearly along the actuator tube.

[0009] Furthermore, a transmission component is sleeved on the outside of the diverter sleeve, which drives the diverter sleeve to rotate, causing the serial hole one to connect with the serial hole two or the serial hole two to connect with the serial hole three to form a connected state, and the limiting component drives the transmission component to move.

[0010] Furthermore, the transmission assembly includes a limiting rod rotatably connected to the regulating chamber through a torsion spring, the top of the limiting rod is connected to gear 2, and the outer side of gear 2 is meshedly connected to gear 1 which is sleeved with the diverter sleeve.

[0011] Furthermore, a spiral block is connected to the bottom of the limiting rod, and a trigger rod is provided on one side of the spiral block. The trigger rod is slidably provided on the actuator tube, and a spiral inclined surface is provided on one side of the spiral block corresponding to the trigger rod. In the initial state, the end of the spiral inclined surface of the spiral block is in sliding contact with the trigger rod, and the trigger rod forces the spiral block to rotate by squeezing the spiral inclined surface.

[0012] Furthermore, the trigger rod is located on the moving track of the swing rod, and the swing rod moves to contact the end of the trigger rod, causing the trigger rod to move toward the spiral block, thereby generating a driving force to drive the spiral block to rotate.

[0018] 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.

[0019] Example 1: See also Figures 1 to 2, the steel mold assembly gap sealing mechanism includes a feeding pipe 01 for feeding, one side of the feeding pipe 01 is connected to an embedded pipe 08 for side glue discharge, the bottom end of the embedded pipe 08 is connected to an executive pipe 06 for bottom glue discharge, the embedded pipe 08 and the executive pipe 06 do not discharge glue at the same time, and the bottom of the executive pipe 06 is also connected to a limiting component for limiting colloid overflow, the feeding pipe 01 is connected to the external glue supply mechanism, the feeding pipe 01 adopts a rigid structure pipeline, the end of the feeding pipe 01 away from the embedded pipe 08 is connected to a hose, the hose is connected to the glue supply machine, and the person holds it The feeding tube 01 can operate the embedded tube 08 and the execution tube 06. The embedded tube 08 is inserted into the steel mold assembly gap to discharge glue from the side. The colloid overflows into the steel mold assembly gap and overflows to both sides at the same time. The overflow amount of the internal colloid is controlled in conjunction with the limitation of the limiting component. At the same time, the overflow amount of the external colloid is manually controlled. When the execution tube 06 is finally pulled out, glue is discharged from the bottom for the final filling, thereby achieving a stable glue discharge amount, reducing excessive or insufficient colloid extending into the steel mold assembly gap, achieving better demolding, and reducing colloid waste.

[0020] In one embodiment, a plurality of overflow holes 04 for discharging glue are provided on the side of the embedded tube 08, and a discharge pipe 11 for discharging glue from the bottom is also connected to the bottom of the execution tube 06. The embedded tube 08 discharges glue from the side through the overflow holes 04, and the execution tube 06 discharges glue from the bottom through the discharge pipe 11 at the bottom.

[0021] In one embodiment, a transmission chamber 20 is further provided in the execution tube 06. A separation cylinder 19 is provided in the transmission chamber 20 and is connected to the serial hole 3 26. The bottom end of the separation cylinder 19 is connected to the discharge pipe 11. The separation cylinder 19 in the transmission chamber 20 divides the bottom of the execution tube 06 into two spaces, so that the spiral block 17, the limiting rod and the colloid are respectively in the two spaces to ensure continuous operation. Example 2: Figures 1 to 5 As shown, the difference between this embodiment and the first embodiment lies in the different ways of diverting the embedded tube 08 and the actuator tube 06; In this embodiment, a transfer tube 02 is connected through the embedded tube 08, one end of the transfer tube 02 is connected to the feed tube 01, and the other end of the transfer tube 02 is connected to a diversion component located in the execution tube 06. The transfer tube 02 conducts the colloid provided in the feed tube 01 and enters the diversion component, thereby realizing the diversion of the colloid, so that the embedded tube 08 and the execution tube 06 can discharge glue at different times.

[0022] In the second embodiment, the diversion assembly includes a control chamber 16 located in the actuator 06, and a diversion sleeve 22 is rotatably connected to the transfer tube 02 in the control chamber 16. The control chamber 16 provides space for the diversion sleeve 22 to rotate. At the same time, under the limitation of the side surfaces of the control chamber 16, the flow of the colloid can be prevented to achieve sealing. The upper and lower sides of the control chamber 16 are respectively provided with a series hole 24 and a series hole 26. The axes of the series hole 24 and the series hole 26 are not located on the same central axis. The upper and lower sides of the diversion sleeve 22 are also respectively provided with two series holes 24 and 26 corresponding to the series hole 24 and the series hole 26. The second serial hole 25 is formed, and the diverter sleeve 22 is connected to the embedded tube 08 through the docking of the second serial hole 25 and the first serial hole 24. The diverter sleeve 22 is connected to the bottom of the actuator tube 06 through the docking of the second serial hole 25 and the third serial hole 26. The rotation of the diverter sleeve 22 drives the rotation of the second serial hole 25, thereby making the second serial hole 25 coaxial with one of the first serial hole 24 or the third serial hole 26, thereby creating a state of mutual communication, so that the colloid enters the space of the embedded tube 08 through the first serial hole 24 and the second serial hole 25 or enters the space of the actuator tube 06 through the second serial hole 25 and the third serial hole 26.

[0023] Example 3: Figures 1 to 5 As shown, the difference between this embodiment and the first embodiment lies in the different ways of driving the diverter sleeve 22 to rotate; In this embodiment, a transmission component is also sleeved on the outer side of the diverter sleeve 22. The transmission component drives the diverter sleeve 22 to rotate, causing the serial hole 1 24 to connect with the serial hole 2 25 or the serial hole 2 25 to connect with the serial hole 3 26 to form a connected state. The transmission component drives the diverter sleeve 22 to rotate, realizing different docking states of the serial hole 1 24 and the serial hole 2 25 or the serial hole 2 25 and the serial hole 3 26.

[0024] In the third embodiment, the transmission assembly includes a limiting rod rotatably connected to the regulating chamber 16 via a torsion spring, the top of the limiting rod is connected to gear 2 23, and the outer side of gear 2 23 is meshingly connected to gear 1 21 which is sleeved with the diverter sleeve 22. When an external force drives the limiting rod to rotate, the limiting rod drives gear 2 23 to rotate, and further drives gear 1 21, forcing the diverter sleeve 22 to rotate. After the external force is released, the torsion spring drives the limiting rod to return, thereby causing the diverter sleeve 22 to return to its initial state, thereby achieving different docking states between the serial hole 1 24 and the serial hole 2 25 or the serial hole 2 25 and the serial hole 3 26.

[0025] In the third embodiment, the bottom of the limiting rod is connected to a spiral block 17, and a trigger rod 18 is provided on one side of the spiral block 17. The trigger rod 18 is slidably set on the actuator tube 06. The top of the trigger rod 18 is inlaid with a rolling ball to reduce the friction between the trigger rod 18 and the spiral block 17. When the trigger rod 18 moves upward, the spiral block 17 is limited by the spiral shape at the bottom, so that the spiral block 17 rotates, thereby driving the rotation of the limiting rod.

[0026] Example 4: Figures 1 to 5 As shown, the difference between this embodiment and the first embodiment lies in the different ways of limiting the colloid output; The limiting component includes a rotating shaft 14 that is rotatably connected to the actuator tube 06 through a torsion spring. The two ends of the rotating shaft 14 are fixed with an expansion plate 05 embedded in the outer side of the actuator tube 06. One side of the expansion plate 05 is also rotatably connected to a swing rod 13. The other end of the swing rod 13 is rotatably connected to a push rod 12. The other end of the push rod 12 is fixed with a limiting frame. The outer side of the limiting frame is fixedly connected with a rubber block 07 that is in sliding contact with the actuator tube 06. During the rotation of the rotating shaft 14, the swing rod 13 is driven to rotate and swing, further pushing the push rod 12. The movable rod 12 drives the rubber block 07 to move, and the rubber block 07 contacts the internal negative angle surface of the steel mold assembly gap, limiting the overflow of part of the colloid. At the same time, after the overflow hole 04 enters the steel mold assembly gap, the overflow hole 04 is forced to expand through external force. The expansion of the overflow hole 04 drives the rotating shaft 14 to rotate, realizing the input of torque. In addition, the overflow hole 04 adopts a semi-flexible steel sheet. In the process of contacting the positive angle of the steel mold assembly gap, the front end part expands from an arc state to a fan-shaped state, further limiting the amount of glue on the positive angle side.

[0027] In the fourth embodiment, the trigger rod 18 is located on one side of the moving trajectory of the swing rod 13. The movement of the swing rod 13 prompts the trigger rod 18 to move, thereby forming a driving force for driving the spiral block 17. During the movement and swinging process of the swing rod 13, the inner side of the swing rod 13 contacts the trigger rod 18, prompting the trigger rod 18 to move toward the inner side of the actuator 06, thereby obtaining the driving force for driving the spiral block 17.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
