Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a rapid erection support structure for building construction formwork. Background Technology

[0002] In building construction, formwork is a temporary support structure. It is made according to design requirements to shape concrete structures and components in the specified positions and geometric dimensions, and to maintain their correct positions. Newly built roofs need support frames to support them, and the formwork can be removed after the roof has completely dried.

[0003] CN210918218U discloses a rapid erection support structure for construction formwork, including a support column and a base. The base is fixedly installed at the bottom of the support column, and the surface of the base has several pin holes. A connecting frame is fixedly installed at the top of the support column, and connecting pipes are fixedly installed at the top and four sides of the connecting frame. Each connecting pipe has a first through hole on its surface, and the connecting pipe is engaged with one end of a connecting rod. Both ends of the connecting rod have second through holes, and the inside of the connecting rod has a through groove. This invention provides a rapid erection support structure for construction formwork. The connecting pipes set by the connecting frame facilitate the installation of connecting rods. The number of connecting rods can be selected according to the actual situation, thus adapting to different situations, improving the scope of application, and facilitating disassembly. It also reduces the space occupied when not in use. The fixed frame can fix the load-bearing plate. However, existing rapid erection support devices for formwork have the following problems during use: the height is generally adjusted by threads, which is inconvenient, the support efficiency is slow, and the support range cannot be adjusted according to the size of the formwork, nor can the support height be finely adjusted. Summary of the Invention

The base has casters at its lower part, and one end of the height adjustment component is fixedly connected to the center of the upper part of the base. The other end of the height adjustment component has a support plate, which contains the height fine-tuning component and an anti-slip pad. The rotation fixing component is fixedly connected to the side wall of the height adjustment component and the side wall of the lateral positioning component, respectively. One end of the support rod is fixedly connected to the height adjustment component, and the other end of the support rod is fixedly connected to the base.

[0006] Furthermore, each height adjustment component includes: a vertical rod, a vertical tube, a plug hole, and a fixing component. The vertical rod has multiple plug holes on its side wall. The vertical rod is sleeved inside the vertical tube, and the vertical rod and the vertical tube are fixedly engaged with the fixing component through the plug holes.

[0007] Furthermore, the fixing component includes: a spacer, a first spring, a movable piece, and a wedge-shaped insertion post. The spacer is fixedly connected to the inner wall of the transverse positioning component. One end of the first spring is fixedly connected to the spacer, and the other end of the first spring is fixedly connected to one end of the movable piece. The other end of the movable piece is provided with a wedge-shaped insertion post. The movable piece is slidably connected to the inner wall of the transverse positioning component.

[0008] Furthermore, the bottom of the vertical rod is fixedly connected to the base; the top of the vertical tube is fixedly connected to the support plate.

[0009] Furthermore, the height fine-tuning component includes: a threaded rod, a handheld disc, a stop rod, a lifting stop plate, a second spring, and an inclined stop groove. The stop rod and the threaded rod are connected by threads. One end of the threaded rod is rotatably connected to the side wall of the vertical pipe, and the other end of the threaded rod is fixedly connected to the handheld disc, which has anti-slip texture. The stop rod passes through a limiting groove at the bottom of the support plate and is inserted into the inclined stop groove of the lifting stop plate. The top of the stop rod contacts the top of the inclined stop groove. A second spring is provided between the lower end of the lifting stop plate and the bottom of the inner wall of the support plate, and the lifting stop plate is slidably connected to the support plate.

[0010] Furthermore, the lifting plate is equipped with an anti-slip pad.

[0011] Furthermore, the lateral positioning component includes: a horizontal tube, a round block, a crossbar, a ball groove, and a ball. The two ends of the horizontal tube are rotatably connected to the side wall of a vertical tube. A partition is provided inside the horizontal tube, and a crossbar is provided inside the horizontal tube between the two partitions. A round block is fixedly connected to both ends of the crossbar. Multiple ball grooves are provided on the side wall of each round block, and a ball is embedded inside the ball groove. The horizontal tube and the crossbar are rotatably connected through the ball.

[0012] Furthermore, the horizontal tube has an opening, and a crossbar located at the opening is fixedly connected to a hand grip.

[0013] Furthermore, the rotating fixing assembly includes: a fixing plate, a fixing column, a pull ring, and a third spring. One end of the fixing plate is fixedly connected to the outer wall of the vertical pipe. The fixing column passes through the fixing plate and is slidably connected to the fixing plate. A pull ring is provided at the top of the fixing column, and a third spring is provided on the fixing column located between the pull ring and the fixing plate.

[0014] Furthermore, a positioning hole is provided on the horizontal tube located on the short axis side of the wedge-shaped plug. When the fixing post is limited by the positioning hole, the long axis side of the wedge-shaped plug is located below the plug hole.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The rapid erection support structure for construction formwork of this invention can quickly support formwork of different heights by setting a height adjustment component. Through the insertion hole, partition, first spring, moving plate and wedge-shaped insertion column in the height adjustment component, the wedge-shaped insertion column can be inserted into the insertion hole and positioned after height adjustment. By holding the handle, the horizontal tube on the outside of the horizontal bar can be rotated to adjust the tilt surface of the wedge-shaped insertion column. Then, when the wedge-shaped insertion column is inserted into the insertion hole, it will not retract into the horizontal tube when subjected to downward pressure, ensuring more stable positioning and thus ensuring more stable overall support of the device.

[0017] 2. The rapid erection support structure for construction templates of this invention, by setting up a height fine-tuning component, allows for adjustment of the lateral movement of the abutment rod when the threaded rod is rotated by the hand-held hand disc. This adjusts the position of the top of the lifting abutment plate extending out of the support plate, thereby achieving the effect of fine-tuning the support position of the overall height of the device, making the support more stable.

[0018] 3. The rapid erection support structure for construction templates of this invention, by setting up a rotating fixing component, allows the third spring to pull the fixing column downward under normal conditions, thereby rotating the horizontal tube on the outside of the horizontal bar. After the inclined surface of the wedge-shaped insertion column is changed, it can be inserted into the positioning hole through the fixing column to position the horizontal tube and prevent the horizontal tube from rotating. This ensures that after the wedge-shaped insertion column is inserted into the insertion hole, it will not change its surface without external force adjustment, thus ensuring the stability of the positioning and preventing the vertical tube on the outside of the vertical bar from sliding after it extends out.

[0024] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, what is described is only a part of the embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figure 1-2 This invention provides a rapid erection support structure for construction templates, consisting of two support units fixedly connected by a lateral positioning component. Each support unit includes: a base 1, a support plate 5, casters 14, a support rod 15, an anti-slip pad 24, a height adjustment component, a height fine-tuning component, and a rotation fixing component. Casters 14 are located at the bottom of the base 1 to facilitate overall movement of the support structure. One end of the height adjustment component is fixedly connected to the center of the top of the base 1. The other end of the height adjustment component has the support plate 5, which contains the height fine-tuning component and the anti-slip pad 24 to prevent the template from slipping. The rotation fixing component is fixedly connected to the side walls of the height adjustment component and the lateral positioning component, respectively. One end of the support rod 15 is fixedly connected to the height adjustment component, and the other end is fixedly connected to the base 1, thereby enhancing the support effect.

[0026] Each height adjustment component includes: a vertical rod 2, a vertical tube 3, insertion holes 4, and a fixing component. The bottom of the vertical rod 2 is fixedly connected to the base 1, and the top of the vertical tube 3 is fixedly connected to the support plate 5. Multiple insertion holes 4 are provided on the side wall of the vertical rod 2. The vertical rod 2 is sleeved inside the vertical tube 3, and the vertical rod 2 and vertical tube 3 are fixedly engaged with the fixing component through the insertion holes 4, allowing for quick support of templates of different heights. The fixing component includes: a partition 7, a first spring 10, a movable piece 11, and a wedge-shaped insertion post 12. The partition 7 is fixedly connected to the inner wall of the transverse positioning component. One end of the first spring 10 is fixedly connected to the partition 7, and the other end of the first spring 10 is fixedly connected to one end of the movable piece 11. The other end of the movable piece 11 is provided with a wedge-shaped insertion post 12. The movable piece 11 is slidably connected to the inner wall of the transverse positioning component.

[0027] The lateral positioning component of this invention includes: a horizontal tube 6, a round block 8, a horizontal bar 9, a ball groove 29, and a ball 30. The two ends of the horizontal tube 6 are rotatably connected to the side wall of a vertical tube 3. A partition 7 is provided inside the horizontal tube 6. A horizontal bar 9 is provided inside the horizontal tube 6 between two partitions. A round block 8 is fixedly connected to the two ends of the horizontal bar 9. A plurality of ball grooves 29 are provided on the side wall of each round block 8. A ball 30 is embedded inside the ball groove 29. The horizontal tube 6 and the horizontal bar 9 are rotatably connected through the ball 30. An opening is provided on the horizontal tube 6. A hand grip 13 is fixedly connected to the horizontal bar 9 located at the opening. When the wedge-shaped plug 12 is inserted into the plug hole 4, it can be positioned after height adjustment. By holding the handle 13, the horizontal tube 6 on the outside of the crossbar 9 is rotated, thereby adjusting the orientation of the inclined surface of the wedge-shaped plug 12. Then, when the wedge-shaped plug 12 is inserted into the plug hole 4, it will not retract into the horizontal tube 6 when the wedge-shaped plug 12 is subjected to downward pressure, ensuring more stable positioning and thus ensuring more stable overall support of the device.

[0028] like Figure 4 The height fine-tuning component of this invention includes: a threaded rod 16, a handheld disc 17, a stop rod 18, a lifting stop plate 19, a second spring 20, and an inclined stop groove 21. The stop rod 18 and the threaded rod 16 are connected by threads. One end of the threaded rod 16 is rotatably connected to the side wall of the vertical tube 3, and the other end of the threaded rod 16 is fixedly connected to the handheld disc 17. The handheld disc 17 is provided with anti-slip texture 23 for easy handling and to prevent slipping. The stop rod 18 passes through the limiting groove 22 at the bottom of the support plate 5 and is inserted into the inclined stop groove 21 of the lifting stop plate 19. The top of the stop rod 18 contacts the top of the inclined stop groove 21. The second spring 20 is provided between the lower end of the lifting stop plate 19 and the bottom of the inner wall of the support plate 5, and the lifting stop plate 19 is slidably connected to the support plate 5. The lifting stop plate 19 is provided with an anti-slip pad 24. The present invention, through the arrangement of a threaded rod 16, a hand-held disc 17, a stop rod 18, a lifting stop plate 19, a second spring 20, an inclined stop groove 21, and a limiting groove 22, ensures that the second spring 20 tends to drive the lifting stop plate 19 downward under normal conditions. When the hand-held disc 17 drives the threaded rod 16 to rotate, the stop rod 18 can be adjusted to move laterally, thereby adjusting the position of the top of the lifting stop plate 19 extending out of the support plate 5. This achieves the effect of fine-tuning the support position of the overall height of the device, making the support more stable.

[0029] like Figure 3The rotating fixing assembly of this invention includes: a fixing plate 25, a fixing post 26, a pull ring 27, and a third spring 28. One end of the fixing plate 25 is fixedly connected to the outer wall of the vertical tube 3. The fixing post 26 passes through the fixing plate 25 and is slidably connected to the fixing plate 25. The top of the fixing post 26 is provided with a pull ring 27, and the fixing post 26 located between the pull ring 27 and the fixing plate 25 is provided with a third spring 28. A positioning hole 31 is provided on the horizontal tube 6 located on one side of the short axis of the wedge-shaped insertion post 12. When the fixing post 26 is limited by the positioning hole 31, the long axis side of the wedge-shaped insertion post 12 is located below the insertion hole 4. Under normal conditions, the third spring 28 pulls the fixed post 26 downward, thereby rotating the horizontal tube 6 on the outside of the horizontal bar 9. After the inclined surface of the wedge-shaped insertion post 12 is changed, it can be inserted into the positioning hole 31 through the fixed post 26 to position the horizontal tube 6 and prevent the horizontal tube 6 from rotating. This ensures that after the wedge-shaped insertion post 12 is inserted into the insertion hole 4, it will not change its surface without external force adjustment, thus ensuring the stability of the positioning and preventing the vertical tube 3 on the outside of the vertical bar 2 from sliding after it extends out.

[0030] The working process of the rapid erection support structure for construction formwork of this invention is as follows: This invention, through the base 1, vertical rod 2, vertical tube 3, and support plate 5, can quickly support formwork of different heights. With the help of the insertion hole 4, partition 7, first spring 10, moving piece 11, and wedge-shaped insertion post 12, the wedge-shaped insertion post 12 can be inserted into the insertion hole 4 for positioning after height adjustment. Using the horizontal tube 6, round block 8, and horizontal rod 9, the distance between the two support plates 5 can be adjusted. Furthermore, by holding the handle 13, the horizontal tube 6 outside the horizontal rod 9 can be rotated, thereby adjusting the orientation of the inclined surface of the wedge-shaped insertion post 12. When the wedge-shaped insertion post 12 is inserted into the insertion hole 4, it will not retract into the horizontal tube 6 when subjected to downward pressure, ensuring more stable positioning and thus ensuring more stable overall support of the device.
