Description

Technical Field

[0001] The present application relates to the field of devices for precast column construction, and in particular, to a formwork system for sealing the warehouse of precast columns in winter. Background Art

[0002] When a precast column is installed on site, the operator needs to clean the pre-installation position, and then hoist and install the precast column. After the connection between the precast column and the pre-installation position is completed, there is a gap between the bottom surface of the precast column and the site plane. At this time, the operator needs to build a formwork for sealing the warehouse to surround the bottom of the precast column, so as to form a closed space between the formwork for sealing the warehouse, the bottom surface of the precast column and the site plane. Finally, grout, that is, cement mortar, is injected into the formwork for sealing the warehouse, so that the cement mortar connects the precast column and the site plane. After waiting for the mortar to solidify, the formwork for sealing the warehouse is removed, and at this time, the installation of the precast column is completed.

[0003] Due to the low temperature in winter, in order to install the precast column smoothly, the operator needs to build a warm shed and equip devices such as a hot air blower, a heat preservation quilt and a fireproof cloth in the warm shed, so that the temperature of the site can ensure that the grouting process can proceed smoothly.

[0004] When installing precast columns in winter, it is first necessary to build a warm shed and equip devices such as a hot air blower, a heat preservation quilt and a fireproof cloth, and then the precast columns can be installed on site, resulting in a long installation time and low installation efficiency of the precast columns. Summary of the Invention

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

[0006] The formwork system for sealing the warehouse of precast columns in winter provided by the present application adopts the following technical solutions:

[0007] A formwork system for sealing the warehouse of precast columns in winter includes four frames with a U-shaped cross-section. Both ends of the upper and lower wing plates of the frame protrude outward along the length direction of the frame to form convex plates. The four frames are surrounded in a circle with their openings facing outwards, and the wing plates of adjacent two frames are pinned together by pins;

[0008] Heating plates are installed in two of the frames. The formwork system for sealing the warehouse includes a temperature sensor and a controller. The controller is electrically connected to the temperature sensor and the heating plates. Heat preservation plates are installed in the other two frames;

[0009] A number of grouting pipes are provided in the frames where the heat preservation plates are installed. The grouting pipes penetrate through the heat preservation plates and the side plates of the frames, and the grouting pipes are fixedly connected to the frames;

[0010] A plurality of blades are hinged in the frame and arranged along the length direction of the frame. The rotation axis of the blades is arranged along the height direction of the frame. A control assembly for controlling the rotation of the blades is further provided on the frame.

[0011] By adopting the above technical solution, after the precast column is in place, the operator places the four frames respectively, makes the four frames face outwards and surround the precast column in a circle, and the side wall of the frame fits with the corresponding side wall of the precast column, and uses pins to connect and fix the frames. Then, cement mortar is injected between the frame and the precast column through the grouting pipe, and the temperature sensor detects the external temperature.

[0012] When the temperature drops to the set value, the temperature sensor transmits the signal to the controller, and the controller controls the heating plate to work, so that the temperature at the precast column rises. At the same time, the operator makes the control assembly work, and the control assembly controls the blades to rotate to be parallel to the side wall of the frame. At this time, the multiple blades cooperate to close the opening of the frame, reducing the heat dissipation at the frame and enabling the temperature at the frame to rise faster. When the temperature sensor detects that the external temperature rises to the set value, the controller controls the heating plate to stop working.

[0013] After the cement mortar dries, the operator pulls out the pins and takes away and collects the four frames respectively for the next use. Since the heating plate works, the temperature at the precast column can ensure the smooth progress of grouting, reducing the situation of building a warming shed, equipping with hot air blowers, thermal insulation quilts and fireproof cloth and other devices before installing the precast column, thereby shortening the time required for installing the precast column and improving the installation efficiency.

[0014] Optionally, a drain hole is opened on the lower wing plate of the frame. A plurality of reinforcing plates arranged along the length direction of the frame are fixedly connected in the frame. The heat preservation plate and the heating plate both penetrate through the corresponding reinforcing plates and are fixed to them. Through holes penetrating the reinforcing plates are opened at the bottom of the reinforcing plates.

[0015] By adopting the above technical solution, the reinforcing plates support the frame, reducing the occurrence of frame deformation. And the reinforcing plates make the heat preservation plate and the heating plate both have gaps with 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 will be formed in the frame during heating, and the water flows to the drain hole through the through holes and is discharged from the frame through the drain hole, reducing the possibility of damage to the heating plate and the heat preservation plate caused by water.

[0016] Optionally, the control assembly includes a pull rod hinged to the left side of the blade. One end of the pull rod away from the blade is hinged with an I-shaped slider. A sliding hole is opened on the upper wing plate of the frame, and the length direction of the sliding hole is arranged along the width direction of the frame. The slider is slidably inserted into the corresponding sliding hole. A connecting rod located above the frame is fixedly connected to the plurality of sliders together. The length direction of the connecting rod is arranged along the length direction of the frame.

[0017] Both ends of the connecting rod are fixedly connected with I-shaped connecting blocks. Connecting holes with the same length direction as the sliding holes are formed in the upper wing plate of the frame. The connecting blocks are slidably inserted into the corresponding connecting holes. A limiting spring is connected to the connecting blocks, and the end of the limiting spring away from the connecting blocks is fixed to the frame;

[0018] The control assembly further includes a limiting block detachably inserted into the connecting hole.

[0019] By adopting the above technical solution, in the initial state, the limiting block is not inserted into the connecting hole, and the limiting spring makes the slider located at the end of the sliding hole away from the open end 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 open end of the frame is in an open state, leaving more space for the grouting operation of the operator and facilitating the operator to carry out grouting; when it is necessary to rotate the blade to close the open end of the frame, the operator pulls the connecting rod in the direction close to the open end of the frame. 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 can cooperate to close the open end of the frame. At this time, the operator inserts the limiting block into the connecting hole, and the limiting block limits the connecting block, the connecting rod, the slider and the pull rod, so that the blade keeps closing the open end of the frame.

[0020] Optionally, a stop block is fixedly connected to the top of the limiting block, and the stop block contacts the upper wing plate of the frame.

[0021] By adopting the above technical solution, the situation that the limiting block falls into the frame is reduced.

[0022] Optionally, a closing assembly for controlling the opening and closing of the water discharge hole is further provided in the frame.

[0023] By adopting the above technical solution, when the open end of the frame is opened, the closing assembly plugs the water discharge hole, reducing the situation that foreign matters in the outside world block the water discharge hole. When the heating plate works and the open end of the frame is closed, the closing assembly controls the water discharge hole to open, and at this time, the water in the frame can flow out of the frame along the water discharge hole.

[0024] Optionally, the closing assembly includes mounting plates arranged on both sides of the water discharge hole. The mounting plates are fixedly connected in the frame. A plug block adapted to the water discharge hole is arranged between the two mounting plates. The plug block is slidably connected to the mounting plates, and the sliding direction of the plug block is arranged along the height direction of the frame;

[0025] A closing spring is connected to the plug block, and the end of the closing spring away from the plug block is fixed to the mounting plate. When the closing spring is not subjected to external force, the plug block is inserted into the water discharge hole;

[0026] A pull rope is fixedly connected to the blocking block. The end of the pull rope away from the blocking block faces upward and is inclined away from the blade, and is fixed to the upper wing plate of the frame.

[0027] A pull ring is fixedly connected to the lower surface of the connection block close to the pull rope, and the pull rope is threaded through the pull ring.

[0028] By adopting the above technical solution, in the initial state, the limit spring is not subjected to external force, the connecting rod, the connection 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 in an open pile shape, the pull rope is in a straight line shape, and the closing spring makes the blocking block inserted into the water discharge hole, so as to close the water discharge hole and reduce the situation that sundries from the outside enter the water discharge hole and block the water discharge hole; when the connecting rod is pulled in the direction close to the opening of the frame, the connecting rod drives the connection block, the slider and the pull rod to move, the pull rod pushes the blade to gradually rotate until it is parallel to the side wall of the frame, the connection block drives the pull ring to move, and the movement of the pull ring makes the pull rope bend, so as to pull the blocking block upward, and at the same time the blocking block compresses the closing spring. When the blade rotates to be parallel to the side wall of the frame, the connecting rod moves in place. At this time, the blocking block completely disengages from the water discharge hole, and the water discharge hole is opened at this time.

[0029] Optionally, sliding blocks corresponding to the mounting plates are fixedly connected to the side wall of the blocking block, sliding grooves adapted to the sliding blocks are formed in the mounting plates, and the length direction of the sliding grooves is arranged along the height direction of the frame.

[0030] By adopting the above technical solution, the cooperation of the sliding block and the sliding groove enables the blocking block to be slidably connected to the mounting plate.

[0031] In summary, the present application includes at least one of the following beneficial technical effects:

[0032] By setting the frame, the heating plate, the heat preservation plate, the grouting pipe, the blade and the control assembly, the time required for installing the precast column is shortened, and the installation efficiency is improved;

[0033] By setting the pull rod, the slider, the connecting rod, the connection block, the limit spring and the limit block, the rotation of the blade can be controlled;

[0034] By setting the mounting plate, the blocking block, the closing spring, the pull rope and the pull ring, the opening and closing of the water discharge hole can be controlled. Description of the Drawings

Detailed implementation manners

[0043] The following further describes the present application in detail in conjunction with the attached Figures 1-7 drawings.

[0044] An embodiment of the present application discloses a formwork system for sealing the bin of a precast column for winter use. Referring to Figures 1 to 3 , it includes four frames 1 with a U-shaped cross-section. At both ends of the upper and lower wing plates of each frame 1, convex plates 11 protrude outward along the length direction thereof; the four frames 1 enclose a ring shape, and the opening of the frame 1 faces outward. The convex plates 11 of adjacent two frames 1 are aligned and are pinned together through pins.

[0045] Each frame 1 is provided with a plurality of reinforcing plates 12, and the plurality of reinforcing plates 12 are arranged along the length direction of the frame 1. Each reinforcing plate 12 is fixed to the inner wall of the frame 1; two of the frames 1 are provided with heat preservation plates 2, and the other two frames 1 are provided with heating plates 3. The length directions of the heating plates 3 and the heat preservation plates 2 are both arranged along the length direction of the frame 1. The heating plates 3 and the heat preservation plates 2 penetrate through the corresponding reinforcing plates 12 and are fixedly connected to the reinforcing plates 12.

[0046] The formwork system for sealing the bin further includes a controller and a temperature sensor, neither of which is shown in the figure. The temperature sensor is used to measure the external temperature, and the controller is electrically connected to both the heating plate 3 and the temperature sensor; referring to Figure 3, in the frame 1 provided with the heat preservation board 2, several grouting pipes 4 are provided. In this embodiment, the number of grouting pipes 4 is three, and the grouting pipes 4 are horizontally arranged. The multiple grouting pipes 4 are uniformly arranged along the length direction of the frame 1. One end of the grouting pipe 4 penetrates through the side plate of the frame 1 and is fixedly connected.

[0047] When closing the bin, the operator places four frames 1 respectively, makes the frame 1 placed on the site plane, and makes the open end of the frame 1 face away from the precast column 5. Then, the frames 1 are connected by pins. The temperature sensor measures the temperature. When the temperature drops to the set temperature value, the temperature sensor transmits the signal to the controller, and the controller controls the heating plate 3 to heat. The operator grouts into the space enclosed by the frame 1 through the grouting pipe 4.

[0048] Due to the operation of the heating plate 3, the temperature at the precast column 5 can ensure the smooth progress of grouting, reducing the situation that it is necessary to build a warm shed, equip a hot air blower, a thermal insulation quilt and a fireproof cloth and other devices before installing the precast column 5, thus shortening the time required for installing the precast column 5 and improving the installation efficiency; when the temperature rises to the set value, the temperature sensor transmits the signal to the controller, and the controller controls the heating plate 3 to stop working.

[0049] Refer to Figure 3 And Figure 4 , in order to enable the temperature at the precast column 5 to rise more quickly, a plurality of blades 6 are hinged in each frame 1. The multiple blades 6 are arranged along the length direction of the frame 1. The rotation axis of the blade 6 is arranged along the height direction of the frame 1. Among them, the grouting pipe 4 is located between two adjacent blades 6; a control assembly 7 for controlling the rotation of the blade 6 is provided on each frame 1.

[0050] By controlling the rotation of the blade 6, the multiple blades 6 can cooperate to block the open side of the frame 1, making the frame 1 form a relatively closed space, reducing the heat loss at the heating plate 3 and the heat preservation board 2, so that the temperature at the precast column 5 can rise more quickly. When the outside temperature is high enough, there is no need to make the blade 6 block the open end of the frame 1, so that more operating space can be left on the open side of the frame 1 for the operator to perform grouting operations better.

[0051] Refer to Figure 4 And Figure 5 , the control assembly 7 includes a pull rod 71 hinged to the left side of the blade 6. The end of the pull rod 71 away from the blade 6 is hinged with an I-shaped slider 72; sliding holes 14 corresponding to the sliders 72 one by one are opened on the upper wing plate of the frame 1. The sliding holes 14 penetrate through the upper wing plate of the frame 1, and the length direction of the sliding holes 14 is arranged along the width direction of the frame 1. Each slider 72 is slidably inserted into 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.

[0052] The control component 7 further includes a connecting rod 73 located above the frame 1. The length direction of the connecting rod 73 is arranged along the length direction of the frame 1. The connecting rod 73 is fixedly connected to each corresponding slider 72. Both ends of the connecting rod 73 are respectively located at the two side edges of the frame 1. Both ends of the connecting rod 73 are fixedly connected with I-shaped connecting blocks 74. Connecting holes 15 corresponding one by one to the connecting blocks 74 are formed on the upper wing plate of the frame 1. The length direction of the connecting holes 15 is the same as the length direction of the sliding holes 14. The connecting blocks 74 are slidably inserted into the corresponding connecting holes 15, and the upper wing plate of the frame 1 is located between the upper and lower wing plates of the connecting blocks 74.

[0053] A limiting spring 75 is arranged in the connecting hole 15. The limiting spring 75 is located on the side of the connecting block 74 close to the open end of the frame 1. One end of the limiting spring 75 is fixed to the connecting block 74, and the other end of the limiting spring 75 is fixed to the hole wall of the end of the connecting hole 15 close to the open end of the frame 1. When the limiting spring 75 is not subjected to an external force, the limiting spring 75 makes the connecting block 74 located at the end of the connecting hole 15 away from the open end of the frame 1. At this time, the angle of the blade 6 makes the open end of the frame 1 in an open state.

[0054] The control component 7 further includes a limiting block 76. The limiting block 76 is detachably inserted into the connecting hole 15. A stopping block 77 is fixedly connected to the upper surface of the limiting block 76. When the limiting block 76 is inserted into the connecting hole 15, the stopping block 77 is located above the frame 1 and the stopping block 77 contacts the upper wing plate of the frame 1, thereby preventing the limiting block 76 from falling into the frame 1. When the limiting block 76 is inserted into the connecting hole 15, the limiting block 76 is located on the side of the connecting block 74 away from the open end of the frame 1. At this time, the limiting spring 75 is compressed, and the angle of the blade 6 makes the open end of the frame 1 in a closed state.

[0055] When installing the frame 1, the limiting block 76 is not inserted into the connecting hole 15. At this time, the angle of the blade 6 makes the open end of the frame 1 in an open state. When the heating plate 3 works, the operator pulls the connecting rod 73 towards the side close to the open end 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 limiting 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 open end of the frame 1. At this time, the operator inserts the limiting block 76 into the connecting hole 15. The limiting 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 open end of the frame 1 can be kept closed.

[0056] Refer to Figure 3 、 Figure 6 and Figure 7, since the blade 6 keeps the frame 1 closed when the heating plate 3 is working, water is likely to accumulate in the frame 1. To enable the water to drain out of the frame 1, a drain hole 13 penetrating the lower wing plate of the frame 1 is provided on the lower wing plate of the frame 1. A through hole 121 penetrating each reinforcing plate 12 is provided on the lower side of each reinforcing plate 12. The water formed during heating can flow through the through hole 121 to the drain hole 13 and finally be discharged out of the frame 1 in time through the drain hole 13, reducing the occurrence of damage to the heating plate 3 and the heat preservation plate 2 caused by water accumulation in the frame 1.

[0057] Due to the complex construction site environment, when placing the frame 1, in order to reduce the occurrence of the drain hole 13 being blocked by debris entering the drain hole 13, a closing component 8 for controlling the opening and closing of the drain hole 13 is also provided in the frame 1. When the blade 6 opens the opening of the frame 1, the closing component 8 blocks the drain hole 13 to reduce the entry of debris into 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.

[0058] The closing component 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 are fixed to the inner wall of the frame 1. A plug 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 plug block 82 is smaller than that of the drain hole 13, so that the plug block 82 can be inserted into the drain hole 13 more smoothly; a sliding block 83 corresponding to each mounting plate 81 is fixedly connected to the side wall of the plug block 82. A sliding groove 811 corresponding to each sliding block 83 is provided on the mounting plate 81. The length direction of the sliding groove 811 is arranged along the height direction of the frame 1. Each sliding block 83 is slidably inserted into the corresponding sliding groove 811. The cooperation between the sliding block 83 and the sliding groove 811 enables the plug block 82 to be slidably connected to the mounting plate 81.

[0059] The upper surface of the sliding block 83 is fixedly connected with a closing spring 84. The closing spring 84 is located in the sliding groove 811, and the upper end of the closing spring 84 is fixedly connected to the top wall of the sliding groove 811. When the limiting spring 75 is not subjected to external force, the limiting spring 75 makes the plug block 82 inserted into the drain hole 13; a pull rope 85 is fixedly connected to the plug block 82. The end of the pull rope 85 away from the plug block 82 faces upward and is inclined away from the opening of the frame 1. The end of the pull rope 85 away from the plug 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 connection block 74 corresponding to the plug block 82, and the pull rope 85 passes through the pull ring 86.

[0060] When the limit block 76 is not inserted into the connection hole 15, the limit spring 75 positions the connection block 74 and the pull ring 86 on the side of the frame 1 away from its opening. At this time, the blade 6 opens the opening of the frame 1, the pull rope 85 is straight, and the closing spring 84 inserts the plug block 82 into the water discharge hole 13. When the connecting rod 73 is pushed to move the connection block 74 and the blade 6 rotates to gradually close the opening of the frame 1, the connection block 74 drives the pull ring 86 to move towards the opening of the frame 1. At the same time, the pull ring 86 drives the pull rope 85 to move, causing the pull rope 85 to gradually fold. During this process, the pull rope 85 pulls the plug block 82 and the sliding block 83 upward and compresses the closing spring 84. When the connecting rod 73 moves in place, the plug block 82 disengages from the water discharge hole 13, and at this time the water discharge hole 13 opens.

[0061] When the limit block 76 is removed from the connection hole 15, the limit spring 75 resumes its deformation and pushes the connecting rod 73, the connection block 74, and the slider 72 towards the side wall of the frame 1. At the same time, the slider 72 cooperates with the pull rod 71 to rotate the blade 6, thereby gradually opening the opening of the frame 1. During this process, the connection block 74 drives the pull ring 86 towards the side wall of the frame 1. The closing spring 84 resumes its deformation and drives the pull rope 85, the sliding block 83, and the plug block 82 to move, causing the plug block 82 to gradually move into the water discharge hole 13 and the pull rope 85 to gradually straighten. When the limit spring 75 returns to its initial state, the connection 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 plug block 82 is inserted into the water discharge hole 13, thereby plugging the water discharge hole 13 again.

[0062] The implementation principle of the precast column bin sealing formwork system for winter use in the embodiment of the present application is as follows: When the precast column 5 is in place for bin sealing, during bin sealing, the operator places four frames 1 respectively, making the side walls of the frames 1 fit against the corresponding side walls of the precast column 5, and fixes the frames 1 by pin connection. After the frames 1 are fixed, cement mortar is injected into the space between the frames 1 and the precast column 5 through the grouting pipe 4. The temperature sensor measures the external temperature. When the temperature drops to the set value, the temperature sensor transmits a signal to the controller, and the controller controls the heating plate 3 to heat. The operator pulls the connecting rod 73 away from the precast column 5. The connecting rod 73 drives the slider 72, the pull rod 71, and the connection block 74 to move. The movement of the pull rod 71 rotates the blade 6. When the connection block 74 moves, it cooperates with the pull rope 85 to move the plug block 82 upward, thereby opening the water discharge hole 13.

[0063] 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 connection hole 15, so as to be able to limit the connecting rod 73, the blade 6 and the plug block 82, and keep the blade 6 closing the opening of the frame 1, and the water discharge 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 water discharge 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.

[0064] When it is necessary to open the opening of the frame 1, the operator takes out the limit block 76 from the connection hole 15. At this time, the limit spring 75 resumes deformation and pushes the connection block 74, the connecting rod 73 and the slider 72 to move towards the precast column 5. The movement of the slider 72 drives the pull rod 71 and the blade 6 to rotate, so that an included angle is gradually formed between the blade 6 and the side wall of the frame 1, and the opening of the frame 1 is gradually opened; at the same time, the closing spring 84 resumes deformation and pushes the plug block 82 to move downward, so that the plug block 82 is inserted into the water discharge hole 13. When both the limit spring 75 and the closing spring 84 return to the initial state, the blade 6 and the plug block 82 both return to the initial position.

[0065] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
