Description

Technical Field

[0001] The present application relates to the field of devices for prefabricated column construction, and in particular to a prefabricated column bunker sealing template system for winter use. Background Art

[0002] When the prefabricated columns are installed on site, the operators need to clean the prefabricated positions and then hoist the prefabricated columns for installation. After the prefabricated columns are connected to the prefabricated positions, there is a gap between the bottom surface of the prefabricated columns and the site plane. At this time, the operators need to build a sealing template to seal the warehouse, thereby surrounding the bottom of the prefabricated columns, so that a closed space is formed between the sealing template, the bottom surface of the prefabricated columns and the site plane. Finally, grouting is done into the sealing template, that is, cement mortar is injected, so that the cement mortar connects the prefabricated columns to the site plane. After waiting for the mortar to solidify, the sealing template is removed, and the installation of the prefabricated columns is completed.

[0003] Due to the low temperature in winter, in order to ensure the smooth installation of prefabricated columns, operators need to build a greenhouse and equip the greenhouse with devices such as hot air blowers, thermal blankets and fireproof cloths, so that the temperature of the site can ensure that the grouting process can proceed smoothly.

[0004] When installing prefabricated columns in winter, it is first necessary to build a greenhouse, equip it with hot air blowers, warm blankets, fire-proof cloth and other devices, and then the prefabricated columns can be installed on site. This results in a long installation time and low installation efficiency. Summary of the invention

[0005] In order to shorten the time of installing prefabricated columns and improve the installation efficiency, the present application provides a prefabricated column sealing formwork system for winter.

[0006] The present application provides a prefabricated column sealing formwork system for winter, which adopts the following technical solution: A prefabricated column warehouse sealing template system for winter, comprising four frames with U-shaped cross-sections, both ends of the upper and lower wing plates of the frames protrude outward along the length direction of the frames to form convex plates, the four frames are open to the outside to form a circle, and the wing plates of two adjacent frames are pinned together by pins; Two of the frames are equipped with heating plates, the sealing template system includes a temperature sensor and a controller, the controller is electrically connected to the temperature sensor and the heating plate, and the other two frames are equipped with insulation plates; A plurality of grouting pipes are provided in the frame for installing the insulation board, the grouting pipes penetrate the insulation board and the side plate of the frame, and the grouting pipes are fixedly connected to the frame; The frame is hinged with a plurality of blades arranged along the length direction of the frame, the rotation axis of the blades is arranged along the height direction of the frame, and the frame is also provided with a control component for controlling the rotation of the blades.

[0007] By adopting the above technical solution, after the prefabricated columns are in place, the operators place four frames respectively so that the four frames are open outward to form a circle around the prefabricated columns, and the side walls of the frames are fitted with the corresponding side walls of the prefabricated columns, and the frames are connected and fixed with pins. Then, cement mortar is injected between the frames and the prefabricated columns through the grouting pipe, and the temperature sensor detects the external temperature.

[0008] When the temperature is lower than the set value, the temperature sensor transmits a signal to the controller, and the controller controls the heating plate to work, so that the temperature at the prefabricated column increases. At the same time, the operator operates the control component, and the control component controls the blades to rotate parallel to the side walls of the frame. At this time, multiple blades cooperate to close the opening of the frame, reducing heat loss at the frame and allowing the temperature at the frame to increase faster. When the temperature sensor detects that the external temperature rises to the set value, the controller controls the heating plate to stop working.

[0009] When the cement mortar is dry, the operator pulls out the pins and collects the four frames separately, waiting for the next use. Due to the operation of the heating plate, the temperature at the prefabricated column can ensure the smooth grouting, reducing the need to build a greenhouse, equip with hot air blowers, thermal blankets, fireproof cloth and other devices before installing the prefabricated column, thereby shortening the time required to install the prefabricated column and improving the installation efficiency.

[0010] Optionally, a drainage hole is provided on the lower wing plate of the frame, and a plurality of reinforcing plates arranged along the length direction of the frame are fixedly connected to the frame. The insulation plate and the heating plate both penetrate the corresponding reinforcing plates and are fixed thereto, and a through hole penetrating the reinforcing plates is provided at the bottom of the reinforcing plates.

[0011] By adopting the above technical solution, the reinforcing plate supports the frame to reduce the deformation of the frame, and the reinforcing plate allows a gap to exist between the insulation plate and the heating plate and the bottom wall of the frame. Since the blades close the opening of the frame during heating, a relatively closed space is formed in the frame. Water is formed in the frame during heating, and the water flows through the through holes to the drain holes and is discharged from the frame through the drain holes, thereby reducing the possibility of water causing damage to the heating plate and the insulation plate.

[0012] Optionally, the control assembly includes a pull rod hinged on the left side of the blade, an I-shaped slider is hinged on one end of the pull rod away from the blade, a sliding hole is opened on the upper wing plate of the frame, and the length direction is arranged along the width direction of the frame, and the slider is slidably inserted in the corresponding sliding hole, and a plurality of sliders are commonly fixedly connected to a connecting rod located above the frame, and the length direction of the connecting rod is arranged along the length direction of the frame; Both ends of the connecting rod are fixedly connected with an I-shaped connecting block, and a connecting hole whose length direction is consistent with the length direction of the sliding hole is opened on the upper wing plate of the frame. The connecting block is slidably inserted in the corresponding connecting hole, and a limit spring is connected to the connecting block. The end of the limit spring away from the connecting block is fixed to the frame; The control component also includes a limit block which is detachably plugged into the connecting hole.

[0013] By adopting the above technical scheme, in the initial state, the limit block is not inserted into the connecting hole, and the limit spring makes the slider located at the end of the sliding hole away from the opening of the frame. At this time, the slider cooperates with the pull rod to make the blade perpendicular to the side wall of the frame. At this time, the opening of the frame is open, leaving more space for the operator's grouting operation, which is convenient for the operator to perform grouting; when the blade needs to be rotated to close the opening of the frame, the operator pulls the connecting rod in the direction close to the opening of the frame, and the connecting rod drives the connecting block and the slider to move. At the same time, the slider cooperates with the pull rod to push the blade to rotate, so that the blade gradually rotates to be parallel to the side wall of the frame. When the blade rotates to be parallel to the side wall of the frame, multiple blades cooperate to close the opening of the frame. At this time, the operator inserts the limit block into the connecting hole, and the limit block limits the connecting block, the connecting rod, the slider and the pull rod, so that the blade remains closed to the opening of the frame.

[0014] Optionally, a stop block is fixedly connected to the top of the limit block, and the stop block is in contact with the upper wing plate of the frame.

[0015] By adopting the above technical solution, the occurrence of the limit block falling into the frame is reduced.

[0016] Optionally, the frame is also provided with a closing component for controlling the opening and closing of the drain hole.

[0017] By adopting the above technical solution, when the opening of the frame is opened, the closing component blocks the drain hole, reducing the occurrence of external debris blocking the drain hole. When the heating plate is working and the opening of the frame is closed, the closing component controls the drain hole to open, and the water in the frame can flow out of the frame along the drain hole.

[0018] Optionally, the closing assembly includes mounting plates arranged on both sides of the drain hole, the mounting plates are fixedly connected in the frame, a blocking block adapted to the drain hole is arranged between the two mounting plates, the blocking block is slidably connected to the mounting plates, and the sliding direction of the blocking block is arranged along the height direction of the frame; The blocking block is connected with a closing spring, one end of the closing spring away from the blocking block is fixed to the mounting plate, and the closing spring is inserted into the drain hole when no external force is applied to the closing spring; A pull rope is fixedly connected to the blocking block, and an end of the pull rope away from the blocking block is tilted upward and away from the blade, and is fixed to the upper wing plate of the frame; A pull ring is fixedly connected to the lower surface of the connection block close to the pull rope, and the pull rope is passed through the pull ring.

[0019] By adopting the above technical scheme, in the initial state, the limit spring is not subjected to external force, the connecting rod, the connecting block and the slider are all located on the side of the frame away from its opening, at this time, the blade is perpendicular to the side wall of the frame, the opening of the frame is an open pile, the pull rope is in a straight line, and the closing spring causes the blocking block to be inserted into the drain hole, thereby closing the drain hole and reducing the occurrence of external debris entering the drain hole and clogging the drain hole; when the connecting rod is pulled in the direction close to the opening of the frame, the connecting rod drives the connecting block, the slider and the pull rod to move, and the pull rod pushes the blade to gradually rotate parallel to the side wall of the frame, and the connecting block drives the pull ring to move, and the movement of the pull ring causes the pull rope to bend, so that the pull rope pulls the blocking block to move upward, and at the same time the blocking block compresses the closing spring, and when the blade rotates to be parallel to the side wall of the frame, the connecting rod moves into place, and the blocking block is completely separated from the drain hole, and the drain hole is open.

[0020] Optionally, a sliding block corresponding to the mounting plate is fixedly connected to the side wall of the blocking block, and a sliding groove adapted to the sliding block is provided on the mounting plate, and the length direction of the sliding groove is arranged along the height direction of the frame.

[0021] By adopting the above technical solution, the sliding block cooperates with the sliding groove to enable the blocking block to be slidably connected with the mounting plate.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-7 This application is described in further detail.

[0032] The present application embodiment discloses a prefabricated column sealing formwork system for winter. Figures 1 to 3 , including four frames 1 with U-shaped cross-sections, both ends of the upper and lower wing plates of each frame 1 protrude outward along the length direction to form a convex plate 11; the four frames 1 form a ring, and the openings of the frames 1 face outward, the convex plates 11 of two adjacent frames 1 are aligned and pinned together.

[0033] Each frame 1 is provided with a plurality of reinforcing plates 12, which are arranged along the length direction of the frame 1, and each reinforcing plate 12 is fixed to the inner wall of the frame 1; two of the frames 1 are provided with insulation plates 2, and the other two frames 1 are provided with heating plates 3, and the length directions of the heating plates 3 and the insulation plates 2 are arranged along the length direction of the frame 1, and the heating plates 3 and the insulation plates 2 both pass through the corresponding reinforcing plates 12 and are fixedly connected to the reinforcing plates 12.

[0034] The sealing template system also includes a controller and a temperature sensor, both of which are not shown in the figure. The temperature sensor is used to measure the external temperature. The controller is electrically connected to the heating plate 3 and the temperature sensor; Figure 3 A plurality of grouting pipes 4 are provided in the frame 1 provided with the insulation board 2. In the present embodiment, the number of the grouting pipes 4 is three, and the grouting pipes 4 are horizontally arranged. The plurality of grouting pipes 4 are evenly arranged along the length direction of the frame 1, and one end of the grouting pipe 4 passes through the side plate of the frame 1 and is fixedly connected.

[0035] When sealing the warehouse, the operator places four frames 1 respectively, places the frames 1 on the site plane, and makes the openings of the frames 1 face away from the prefabricated columns 5, and then connects the frames 1 through pins. The temperature sensor measures the temperature. When the temperature is lower than the set temperature value, the temperature sensor transmits the signal to the controller. The controller controls the heating plate 3 to heat, and the operator grouts the space enclosed by the frames 1 through the grouting pipe 4.

[0036] Due to the operation of the heating plate 3, the temperature at the prefabricated column 5 can ensure the smooth grouting, reducing the need to build a greenhouse, equip with hot air blowers, thermal blankets, fireproof cloths and other devices before installing the prefabricated column 5, thereby shortening the time required for installing the prefabricated column 5 and improving the installation efficiency; when the temperature rises to the set value, the temperature sensor transmits a signal to the controller, and the controller controls the heating plate 3 to stop working.

[0037] Reference Figure 3 and Figure 4 In order to increase the temperature of the prefabricated column 5 more quickly, a plurality of blades 6 are hinged in each frame 1, and the plurality of blades 6 are arranged along the length direction of the frame 1, and the rotation axis of the blade 6 is arranged along the height direction of the frame 1, wherein the grouting pipe 4 is located between two adjacent blades 6; and a control component 7 for controlling the rotation of the blade 6 is provided on each frame 1.

[0038] By controlling the rotation of the blades 6, the multiple blades 6 can cooperate to block the open side of the frame 1, so that the frame 1 forms a relatively closed space, reducing the heat loss at the heating plate 3 and the insulation plate 2, so that the temperature at the prefabricated column 5 can be increased more quickly. When the outside temperature is high enough, there is no need for the blades 6 to block the open side of the frame 1, so that more operating space can be reserved on the open side of the frame 1 for operators to better perform grouting operations.

[0039] Reference Figure 4 and Figure 5 The control assembly 7 includes a pull rod 71 hinged on the left side of the blade 6, and an I-shaped slider 72 is hinged on the end of the pull rod 71 away from the blade 6; a sliding hole 14 corresponding to the slider 72 is opened on the upper wing plate of the frame 1, and the sliding hole 14 passes through the upper wing plate of the frame 1, and the length direction of the sliding hole 14 is set along the width direction of the frame 1, each slider 72 is slidably inserted in the corresponding sliding hole 14, and the upper wing plate of the frame 1 is located between the upper and lower wing plates of the slider 72.

[0040] The control assembly 7 also includes a connecting rod 73 located above the frame 1. The length direction of the connecting rod 73 is set along the length direction of the frame 1. The connecting rod 7 is fixedly connected to each corresponding slider 72; the two ends of the connecting rod 73 are respectively located at the two side edges of the frame 1, and the two ends of the connecting rod 73 are fixedly connected with an I-shaped connecting block 74. The upper wing plate of the frame 1 is provided with a connecting hole 15 corresponding to the connecting block 74 one by one. The length direction of the connecting hole 15 is consistent with the length direction of the sliding hole 14. The connecting block 74 is slidably inserted in the corresponding connecting hole 15, and the upper wing plate of the frame 1 is located between the upper and lower wing plates of the connecting block 74.

[0041] A limit spring 75 is provided in the connecting hole 15. The limit spring 75 is located on the side of the connecting block 74 close to the opening of the frame 1. One end of the limit spring 75 is fixed to the connecting block 74, and the other end of the limit spring 75 is fixed to the hole wall of the connecting hole 15 close to the opening of the frame 1. When the limit spring 75 is not subjected to external force, the limit spring 75 makes the connecting block 74 located at the end of the connecting hole 15 away from the opening of the frame 1. At this time, the angle of the blade 6 makes the opening of the frame 1 open.

[0042] The control component 7 also includes a limit block 76, which is detachably inserted in the connecting hole 15, and a stop block 77 is fixedly connected to the upper surface of the limit block 76. When the limit block 76 is inserted in the connecting hole 15, the stop block 77 is located above the frame 1, and the stop block 77 contacts the upper wing plate of the frame 1, thereby preventing the limit block 76 from falling into the frame 1; when the limit block 76 is inserted in the connecting hole 15, the limit block 76 is located on the side of the connecting block 74 away from the opening of the frame 1. At this time, the limit spring 75 is compressed, and the angle of the blade 6 makes the opening of the frame 1 closed.

[0043] When installing the frame 1, the limit block 76 is not inserted into the connecting hole 15. At this time, the angle of the blade 6 makes the opening of the frame 1 open. When the heating plate 3 is working, the operator pulls the connecting rod 73 to the side close to the opening of the frame 1. The connecting rod 73 drives the connecting block 74 and the slider 72 to move. The movement of the connecting block 74 compresses the limit spring 75. At the same time, the slider 72 drives the pull rod 71 to move, so that the pull rod 71 pushes the blade 6 to rotate; when the blade 6 rotates to be parallel to the side wall of the frame 1, multiple blades 6 cooperate to close the opening of the frame 1. At this time, the operator inserts the limit block 76 into the connecting hole 15. The limit block 76 limits the connecting block 74, the connecting rod 73 and the slider 72, so that the blade 6 maintains the current angle and the opening of the frame 1 can remain closed.

[0044] Reference Figure 3 , Figure 6 and Figure 7Since the blades 6 keep the frame 1 closed when the heating plate 3 is working, water is easily accumulated in the frame 1. In order to allow the water to drain out of the frame 1, a drainage hole 13 penetrating the lower wing plate of the frame 1 is provided on the lower wing plate of the frame 1, and a through hole 121 penetrating therethrough is provided on the lower side of each reinforcing plate 12. Water formed during heating can flow to the drainage hole 13 through the through hole 121, and finally be discharged to the outside of the frame 1 in time through the drainage hole 13, thereby reducing the occurrence of water accumulation in the frame 1 causing damage to the heating plate 3 and the insulation plate 2.

[0045] Due to the complex environment of the construction site, when placing the frame 1, in order to reduce the possibility of debris entering the drain hole 13 and causing the drain hole 13 to be blocked, the frame 1 is also provided with a closing component 8 for controlling the opening and closing of the drain hole 13. When the blade 6 opens the opening of the frame 1, the closing component 8 blocks the drain hole 13 to reduce the possibility of debris entering the drain hole 13; when the blade 6 closes the opening of the frame 1, the closing component 8 opens the drain hole 13, so that the water in the frame 1 can flow out along the drain hole 13.

[0046] The closing assembly 8 includes mounting plates 81 located on both sides of the drain hole 13. The mounting plates 81 are parallel to the reinforcing plates 12, and the mounting plates 81 are fixed to the inner wall of the frame 1. A blocking block 82 adapted to the drain hole 13 is provided between the two mounting plates 81. The cross-sectional area of ​​the lower end of the blocking block 82 is smaller than the drain hole 13, so that the blocking block 82 can be inserted into the drain hole 13 more smoothly; sliding blocks 83 corresponding to the mounting plates 81 are fixedly connected to the side walls of the blocking blocks 82, and sliding grooves 811 corresponding to the sliding blocks 83 are provided on the mounting plates 81. The length direction of the sliding grooves 811 is arranged along the height direction of the frame 1, and each sliding block 83 is slidably inserted in the corresponding sliding groove 811. The sliding block 83 cooperates with the sliding groove 811 to enable the blocking block 82 to be slidably connected to the mounting plate 81.

[0047] A closing spring 84 is fixedly connected to the upper surface of the sliding block 83, and the closing spring 84 is located in the sliding groove 811. The upper end of the closing spring 84 is fixedly connected to the top groove wall of the sliding groove 811. When the limit spring 75 is not subjected to external force, the limit spring 75 causes the blocking block 82 to be inserted into the drain hole 13; a pull rope 85 is fixedly connected to the blocking block 82, and the end of the pull rope 85 away from the blocking block 82 is upward and inclined in the direction away from the opening of the frame 1, and the end of the pull rope 85 away from the blocking block 82 is fixedly connected to the upper wing plate of the frame 1; a pull ring 86 is fixedly connected to the lower surface of the connecting block 74 corresponding to the blocking block 82, and the pull rope 85 is passed through the pull ring 86.

[0048] When the limit block 76 is not inserted into the connecting hole 15, the limit spring 75 makes the connecting block 74 and the pull ring 86 located on the side of the frame 1 away from its own opening. At this time, the blade 6 opens the opening of the frame 1, the pull rope 85 is in a straight line, and the closing spring 84 makes the blocking block 82 inserted in the drainage hole 13; when the connecting rod 73 is pushed to move the connecting block 74, and the blade 6 rotates to gradually close the opening of the frame 1, the connecting block 74 drives the pull ring 86 to move toward the opening of the frame 1, and at the same time, the pull ring 86 drives the pull rope 85 to move, so that the pull rope 85 is gradually folded. In this process, the pull rope 85 pulls the blocking block 82 and the sliding block 83 upward, and compresses the closing spring 84. When the connecting rod 73 moves into place, the blocking block 82 is separated from the drainage hole 13, and the drainage hole 13 is opened.

[0049] When the limit block 76 is taken out from the connecting hole 15, the limit spring 75 restores its deformation and pushes the connecting rod 73, the connecting block 74 and the slider 72 to move toward the side wall of the frame 1, and at the same time, the slider 72 cooperates with the pull rod 71 to rotate the blade 6, so that the opening of the frame 1 is gradually opened; in this process, the connecting block 74 drives the pull ring 86 to move toward the side wall of the frame 1, and the closing spring 84 restores its deformation and drives the pull rope 85, the sliding block 83 and the blocking block 82 to move, so that the blocking block 82 gradually moves into the drainage hole 13, and at the same time, the pull rope 85 gradually straightens. When the limit spring 75 returns to its initial state, the connecting block 74, the closing spring 84, the pull ring 86 and the pull rope 85 also return to their initial positions. At this time, the blocking block 82 is inserted into the drainage hole 13, thereby blocking the drainage hole 13 again.

[0050] The implementation principle of a prefabricated column warehouse sealing template system for winter in an embodiment of the present application is as follows: when the prefabricated column 5 is in place, the warehouse is sealed. When sealing, the operator places four frames 1 respectively so that the side walls of the frames 1 are in contact with the corresponding side walls of the prefabricated columns 5, and the frames 1 are fixed by pins. After the frames 1 are fixed, cement mortar is injected into the space between the frames 1 and the prefabricated columns 5 through the grouting pipe 4. The temperature sensor measures the external temperature. When the temperature is lower than the set value, the temperature sensor transmits a signal to the controller. The controller controls the heating plate 3 to heat up. The operator pulls the connecting rod 73 in the direction away from the prefabricated column 5. The connecting rod 73 drives the slider 72, the pull rod 71 and the connecting block 74 to move. The movement of the pull rod 71 causes the blade 6 to rotate. When the connecting block 74 moves, it cooperates with the pull rope 85 to move the blocking block 82 upward, thereby opening the drain hole 13.

[0051] When the blades 6 rotate to be parallel to the side wall of the frame 1, the multiple blades 6 cooperate to close the opening of the frame 1. At this time, the operator inserts the limit block 76 into the connecting hole 15, so as to limit the connecting rod 73, the blades 6 and the block 82, so that the blades 6 keep closing the opening of the frame 1, and the drain hole 13 remains open. The water generated during the heating process can be discharged to the outside of the frame 1 in time through the drain hole 13. When the temperature rises to the set value, the temperature sensor transmits a signal to the controller, and the controller controls the heating plate 3 to stop working.

[0052] When the opening of the frame 1 needs to be opened, the operator takes the limit block 76 out of the connecting hole 15, at which time the limit spring 75 recovers its deformation and pushes the connecting block 74, the connecting rod 73 and the slider 72 to move toward the prefabricated column 5, and the movement of the slider 72 drives the pull rod 71 and the blade 6 to rotate, so that the blade 6 gradually forms an angle with the side wall of the frame 1, and the opening of the frame 1 gradually opens; at the same time, the closing spring 84 recovers its deformation and pushes the block 82 to move downward, so that the block 82 is inserted into the drain hole 13. When the limit spring 75 and the closing spring 84 are restored to the initial state, the blade 6 and the block 82 are restored to the initial position.

[0053] 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.
