Description

Technical Field

[0001] The present invention relates to the field of construction technology, and particularly to an improved early-demolition component for a concrete forming template and an early-demolition formwork support. Background Art

[0002] Figure 1 And Figure 2 is an early-demolition component of a concrete forming template in the prior art, which mainly includes a lead screw 100, an early-demolition support plate 200, and a blocking rod 300. A clamping space is formed between the blocking rod 300 and the lead screw 100. The user places the main beam 1 in the clamping space to achieve the positioning of the main beam 1. The early-demolition support plate 200 can rotate along the lead screw 100 to realize lifting and lowering. Among them, the lifting and lowering blocking rod 300 adopts a threaded structure. By means of screwing and rotating, the blocking rod 300 realizes up and down lifting. During installation, after the blocking rod 300 rotates upward, a clamping space is formed between it and the lead screw 100. When the concrete solidifies and is demolished, the blocking rod 300 rotates downward, and the clamping space between it and the lead screw 100 disappears. Rotate the early-demolition support plate 200 and lower it along the lead screw to complete the demolition. However, the blocking rod 300 adopts a threaded structure, and realizes up and down lifting by means of screwing and rotating. In the process of using this method, if the lifting range is relatively large, the threaded section needs to be designed relatively long, and it takes a long time to screw and rotate, which is time-consuming. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this purpose, the present invention provides an improved early-demolition component for a concrete forming template, which can improve the installation and demolition efficiency.

[0004] An improved early-demolition component for a concrete forming template according to an embodiment of the first aspect of the present invention includes:

[0005] A lead screw, a support plate at the end of the lead screw; an early-demolition support plate, the early-demolition support plate is provided with a channel that is in threaded cooperation with the lead screw, two relatively arranged connecting seats extend along both sides of the diameter direction of the early-demolition support plate, the connecting seats are provided with opening grooves, and a support rod is horizontally arranged in the opening grooves; a blocking rod, one end of the blocking rod is a blocking end, the other end is a limiting end, a strip-shaped hole is provided on the blocking rod, the strip-shaped hole is arranged along the length direction of the blocking rod, the strip-shaped hole is arranged close to the limiting end, and the blocking rod is rotatably connected to the support rod through the strip-shaped hole.

[0006] The improved early-demolition component of the concrete forming formwork according to the embodiments of the present invention has at least the following beneficial effects: By providing a strip-shaped hole on the blocking rod, the blocking rod is rotatably connected to the support rod through the strip-shaped hole. When the main beam needs to be installed, when the blocking end is facing upwards, the blocking rod is lowered to make its vertical positioning. A clamping space is formed between the blocking end and the lead screw, so that the main beam can be installed in the clamping space. When the concrete solidifies and reaches the time when it can be demolished, the blocking rod is lifted and rotated along the strip-shaped hole, so that the blocking end faces downwards, causing the clamping space to disappear. Then, the early-demolition formwork is rotated to make it descend along the lead screw, and the demolition can be completed. Compared with the prior art, this solution only requires the blocking rod to undergo simple lifting and rotation steps to realize the formation and cancellation of the clamping space. Compared with the method using bolts, the construction is more convenient and simple, saving labor and time, and the production of the early-demolition formwork assembly is simpler.

[0007] According to some embodiments of the present invention, a relief groove is provided at the bottom of the opening groove, and the relief groove extends from the lower end to the upper end of the early-demolition formwork.

[0008] According to some embodiments of the present invention, the limiting end of the blocking rod is arc-shaped.

[0009] According to some embodiments of the present invention, two limiting members are provided on the support rod, and the two limiting members are respectively arranged on both sides of the blocking rod to limit the movement of the blocking rod along the support rod.

[0010] According to some embodiments of the present invention, a limiting member is further included, and the limiting member is arranged on the lead screw to limit the further upward movement of the early-demolition formwork on the lead screw.

[0011] According to some embodiments of the present invention, the limiting member is a stop ring, and the stop ring can be clamped in the thread groove of the lead screw.

[0012] According to some embodiments of the present invention, the limiting device is a snap ring, and the snap ring can be clamped in the thread groove of the lead screw.

[0013] An early-demolition formwork support according to the second aspect embodiment of the present invention: includes a vertical rod, and the improved early-demolition component of the concrete forming formwork as described above is inserted at the end of the vertical rod.

[0014] The early demolition formwork support according to the embodiment of the present invention has at least the following beneficial effects: By providing a strip-shaped hole on the blocking rod, the blocking rod is rotatably connected to the support rod through the strip-shaped hole. When positioning and installing the main beam, the blocking rod is lifted, rotated to the facing position and then lowered to vertically position the blocking rod, forming a clamping space between the blocking end and the screw rod, so that the main beam can be installed in the clamping space. When the concrete solidifies and reaches the time when it can be demolished, the blocking rod is lifted and rotated along the strip-shaped hole, making the blocking end face downward, so that the clamping space disappears. Then, the early demolition support plate is rotated and lowered along the screw rod to complete the demolition. Compared with the prior art, this solution only requires simple lifting and rotating steps of the blocking rod to form and cancel the clamping space. Compared with the method using bolts, the construction is more convenient and simple.

[0040] The following refers to Figures 3 to 9 Describe an improved early demolition component of a concrete forming template according to an embodiment of the present invention.

[0041] As Figure 3 and Figure 4 shown, the improved early demolition component of the concrete forming template according to the embodiment of the present invention includes:

[0042] A lead screw 100 and a support plate 110 at the end of the lead screw 100;

[0043] An early demolition plate 200 is provided with a channel 210 that is threadedly engaged with the lead screw 100. Two oppositely arranged connecting seats 220 extend along both sides in the diameter direction of the early demolition plate 200. The connecting seat 220 is provided with an opening groove 221, and a support rod 230 is horizontally arranged in the opening groove 221;

[0044] A blocking rod 300, one end of the blocking rod 300 is a blocking end 310, the other end is a limiting end 320. The blocking rod 300 is provided with a strip-shaped hole 330 that is arranged along the length direction of the blocking rod 300. The strip-shaped hole 330 is arranged close to the limiting end 320. The blocking rod 300 is rotatably connected to the support rod 230 through the strip-shaped hole 330.

[0045] Specifically, the lead screw 100 mainly plays a supporting role during work, and the support plate 110 is used to support the top mold plate 2, and a concrete layer will be laid on the mold plate 2.

[0046] Among them, the early demolition plate 200 is selected to be a disc-shaped structure. The early demolition plate 200 is rotatably installed on the lead screw 100 through the channel 210. By rotating along the lead screw 100, the up and down position of the early demolition plate 200 can be adjusted.

[0047] The strip hole 330 provided on the blocking rod 300 is relatively close to the limiting end 320, so that the length between the strip hole 330 and the limiting end 320 is relatively short, and the limiting end 320 can cooperate with the bottom end of the early disassembly support plate 200 during use to achieve the purpose of limiting the rotation of the blocking rod 300. The length between the strip hole 330 and the blocking end 310 is relatively long, and when the blocking end is facing upward, the blocking rod is lowered to be vertically positioned, which can achieve the purpose of blocking the main beam 1.

[0048] like Figure 4 and Figure 5 As shown, the blocking rod 300 is rotatably connected to the support rod 230 through the strip hole 330. During the construction process, when the main beam 1 needs to be positioned and installed, the blocking end 310 is turned to the upward position, that is, Figure 5 At this time, the blocking end 310 and the screw rod 100 together form an embedding space 400, and the main beam 1 is installed in the embedding space 400, which can realize the positioning of the main beam 1 and limit its displacement.

[0049] Figure 6 This is a schematic diagram of the force analysis of the blocking rod 300 at this time. The blocking ends 310 and the limiting ends 320 at both ends of the blocking rod 300 and the support rod 230 together form a lever effect. At this time, even if the main beam 1 moves toward the blocking end 310 and the blocking end 310 is subjected to force, the bottom end of the early dismantling support plate 200 will resist the limiting end 320 and limit the rotation of the limiting end 320. Therefore, at this time, even if the blocking end 310 is subjected to force, it will not rotate.

[0050] When the concrete on the mold plate 2 is completely solidified and the supporting components are ready for removal, Figure 7 and Figure 8 As shown, first, the blocking rod 300 is lifted along the strip hole 330, so that the limiting effect between the limiting end 320 and the bottom end of the early removal support plate 200 disappears, and then the blocking rod 300 can be rotated until the blocking end 310 is turned downward, that is, entering Figure 8 The state of the embedded space 400 is cancelled. Then the early dismantling support plate 200 is rotated to make it descend along the screw rod 100, and the main beam 1, the secondary beam 4 and the mold plate 2 can be removed.

[0051] Compared with the prior art, the present application solution only requires the blocking rod 300 to undergo simple steps such as lifting and rotating to achieve the formation and removal of the embedded space 400. Compared with the method of using bolts, the construction is more convenient and simple, and it consumes less time.

[0052] In some embodiments of the present invention, a groove bottom of the opening groove 221 is provided with a clearance groove 240 , and the clearance groove 240 extends from the lower end of the early removal pallet 200 to the upper end of the early removal pallet 200 .

[0053] refer toFigures 4 to 8 As shown, a relief groove 240 is provided at the bottom of the opening groove 221. When the blocking rod 300 rotates, a relief space can be provided for the end of the limiting end 320, which can reduce the distance between the early demolition formwork 200 and the bottom of the opening groove 221, and reduce the amplitude of the shaking of the blocking rod 300. The stability of the positioning of the blocking rod 300 is improved.

[0054] In some embodiments of the present invention, as Figure 9 shown, the limiting end 320 of the blocking rod 300 is arc-shaped. The limiting end 320 is designed to be arc-shaped to reduce the interference with the bottom of the opening groove 221, making the rotation process of the blocking rod 300 smoother.

[0055] In some embodiments of the present invention, two limiting members 500 are provided on the support rod 230. The two limiting members 500 are respectively arranged on both sides of the blocking rod 300 to limit the movement of the blocking rod 300 along the support rod 230, thereby reducing the possibility of the blocking rod 300 shaking to both sides during the working process and improving the stable and reliable performance of the component.

[0056] In some embodiments of the present invention, as Figure 3 shown, a limiting device 700 is further included. The limiting device 700 is arranged on the lead screw 100 to limit the further upward movement of the early demolition formwork 200 on the lead screw 100.

[0057] By setting the limiting device 700, when the early demolition formwork 200 rotates and moves upward on the lead screw, after moving upward to a certain position, the limiting device 700 will limit the further upward movement of the early demolition formwork 200. If the surface of the support formwork 110 is flush with the mold plate 2 at this time, the surface of the early demolition formwork 200 just abuts against the main beam 1. In this way, it can be avoided that workers need to measure and adjust the distance between the early demolition formwork 200 and the support formwork 110 during the operation process, so that the adjustment is simpler and the labor for adjusting the height is saved.

[0058] Furthermore, the limiting member 700 is a stop ring, and the stop ring can be clamped in the thread groove of the lead screw 100. When the stop ring is clamped in the thread groove of the lead screw 100, during the rotation and upward movement of the early demolition formwork 200, when encountering the stop ring, due to the limiting effect of the stop ring, the early demolition formwork 200 cannot continue to rotate and move upward, thus achieving the limiting effect. At the same time, the position of the stop ring can be adjusted according to the needs of the engineering project and clamped at different height positions, which is convenient for adjustment, thereby improving the applicability of the product.

[0059] In another embodiment, the limiting member 700 is a snap ring, which can be clamped in the thread groove of the lead screw 100. Similarly, when the snap ring is clamped in the thread groove of the lead screw 100, during the upward rotation of the early removal formwork support plate 200, when encountering the snap ring, due to the limiting effect of the snap ring, the early removal formwork support plate 200 cannot continue to rotate upward, thus achieving the limiting effect. At the same time, the clamping position of the snap ring can be adjusted according to the needs of the engineering project and clamped at different height positions, which is convenient for adjustment, thereby improving the applicability of this product.

[0060] As Figure 10 shown, the present invention also discloses an early removal formwork support, which includes a vertical rod 600, and the improved concrete forming formwork early removal member described above is inserted at the end of the vertical rod 600.

[0061] As Figure 11 shown, the weight of the concrete slab 3 and the construction load are transmitted from the formwork plate 2 to the early removal formwork support plate 200, and then from the lead screw 100 to the vertical rod 600. The vertical rod 600 increases the overall support height of the member, providing support force for the main beam 1, the secondary beam 4, the formwork plate 2 and the load above.

[0062] As Figure 12 shown, when the strength of the concrete slab 3 reaches the early removal condition, after the blocking end 310 of the blocking rod 300 rotates downward, the early removal formwork support plate 200 rotates downward. After the early removal formwork support plate 200 descends, the main beam 1 becomes loose, and then the main beam 1 and the formwork plate 2 are removed for the next turnover. At this time, the weight of the formed concrete slab 3 and the construction load are transmitted from the concrete slab 3 to the support plate 110 and then from the lead screw 100 to the vertical rod 600.
