Description

Technical Field

[0001] This application relates to the technical field of building construction, and in particular to a roof slab formwork support system structure. Background Technology

[0002] In the field of building construction, the roof slab formwork support system is a key structure for ensuring the casting and shaping of concrete roof slabs and the safety of construction. Its main function is to bear the self-weight of the newly poured concrete, the self-weight of the formwork and supports, and the loads of construction personnel and equipment, requiring sufficient load-bearing capacity, rigidity, and stability. With the development of industrialized construction, the ease of adjustment, turnover efficiency, and construction safety of the roof slab formwork support system have become important factors in improving construction quality and progress, and it is widely used in the roof slab construction of various concrete structure projects such as residential and public buildings.

[0003] Current roof slab formwork support structures typically use open supports to lift the keel from below. When the support is under pressure, tilting can easily occur between the support and the keel, causing the support to be unable to stably support the keel and affecting the stability of the roof slab formwork support. Utility Model Content

[0004] The purpose of this application is to provide a roof slab formwork support system structure, which has the advantages of enabling the support uprights to provide stable support for the load-bearing keel, effectively preventing relative tilting between the support uprights and the load-bearing keel when the support is under pressure, and ensuring that the support uprights always maintain a vertical support state with the load-bearing keel, thereby improving the stability of the roof slab formwork support. It solves the problem that the current roof slab formwork support structure usually uses an open support to lift the keel from below, which easily leads to tilting between the support and the keel when the support is under pressure, resulting in the support not being able to stably support the keel and affecting the stability of the roof slab formwork support.

[0005] The technical solution of the roof formwork support system structure provided in this application is as follows: A roof formwork support system structure includes a load-bearing keel, a connecting component is provided at the bottom of the load-bearing keel, the connecting component includes a sliding groove, a plurality of sliders are slidably arranged inside the sliding groove, a connecting sleeve is fixedly provided at the bottom of the sliders, a plug rod is inserted into the inner wall of the middle part of the connecting sleeve, the specifications of the outer surface of the middle part of the plug rod are adapted to the specifications of the inner wall of the middle part of the connecting sleeve, the plug rod is fixedly arranged at the top of the support column, and an adjustment component is provided at the bottom end of the support column, the adjustment component is arranged at the top of the support base plate.

[0006] By adopting the above technical solution, the load-bearing keel provides the main load-bearing foundation for the top slab formwork, and the sliding groove in the connecting component provides sliding guidance for the slider, so that multiple sliders can be adjusted in position within the sliding groove according to the support requirements, thereby driving the connecting sleeve to adjust its distribution position. The connecting sleeve and the plug-in rod adopt a plug-in fit, and the two are compatible in specifications, which can play a positioning role in the connection between the support pole and the load-bearing keel, preventing the support pole from shifting under pressure. This effectively avoids the problem that traditional open supports are prone to tilting and cannot make stable contact with the keel to support the support when the support is under pressure. At the same time, the support base plate increases the contact area with the ground, improving the stability of the bottom end of the support pole on the ground.

[0007] Preferably, the adjusting component includes a threaded rod, which is fixedly disposed at the bottom end of the supporting upright. The outer surface of the middle part of the threaded rod is threadedly connected to the inner wall of the middle part of the threaded sleeve, and the bottom end of the threaded sleeve is rotatably disposed at the top of the supporting base plate.

[0008] By adopting the above technical solution, the threaded rod in the adjustment component is fixedly connected to the support column, and the threaded sleeve is threadedly engaged with the threaded rod. The bottom end of the threaded sleeve is rotatably mounted on the top of the support base plate. When the threaded sleeve is rotated, the threaded rod can move up and down along the axial direction of the threaded sleeve using the principle of thread transmission, thereby driving the support column to rise and fall synchronously. This achieves precise adjustment of the support column height to adapt to the support requirements of top plate templates of different heights. Furthermore, the adjustment component is located at the bottom of the support column, allowing for convenient adjustment of the support column height from below without the need for a climbing frame, thus improving the safety of adjusting the support column.

[0009] Preferably, a worm gear is fixedly provided on the outer surface of the middle part of the threaded sleeve, the worm gear meshes with the worm, the outer surfaces of both ends of the worm are rotatably mounted on the top of the support base plate through the support frame, and a screwing head is fixedly provided at the end of the worm.

[0010] By adopting the above technical solution, the worm gear on the outer surface of the threaded sleeve meshes with the worm. The worm is rotatably mounted on the top of the support base plate via a support frame. The screwing head at the end facilitates the operator to rotate the worm. When the screwing head is rotated, the worm drives the worm gear to rotate, which in turn drives the threaded sleeve to rotate synchronously, thereby adjusting the height of the support pole. The cooperation between the worm gear and the worm allows for precise adjustment of the support pole height. Furthermore, the self-locking performance of the worm gear and worm transmission effectively prevents the threaded sleeve from rotating on its own due to the pressure of the support pole after adjustment, ensuring that the support pole height remains stable and avoiding the separation of the connecting sleeve and the insertion rod due to changes in support height caused by accidental rotation of the threaded sleeve, further improving the reliability of the support system.

[0011] Preferably, the bottom end of the support rod has a limiting hole, the limiting hole extends downward and penetrates the middle inner wall of the threaded rod, the inner wall of the limiting hole is inserted into a limiting rod, the bottom end of the limiting rod is fixedly set on the top of the support base plate, the shape of the middle outer surface of the limiting rod is polygonal, and the shape of the middle outer surface of the limiting rod is adapted to the shape of the inner wall of the limiting hole.

[0012] By adopting the above technical solution, the limiting hole at the bottom of the support pole is inserted into the limiting rod at the top of the support base plate, and the outer surface of the middle part of the limiting rod is polygonal, which matches the shape of the inner wall of the limiting hole. This can restrict the relative rotation between the support pole and the limiting rod. When the height of the support pole is adjusted by adjusting the component, the support pole can only move up and down along the axial direction of the limiting rod, and will not rotate circumferentially. This allows the threaded sleeve to stably drive the support pole to adjust its height when rotating.

[0013] Preferably, a guide cover is fixedly provided at the bottom opening of the connecting sleeve, and the guide cover is arranged in a downward and outward expansion shape.

[0014] By adopting the above technical solution, the guide cover at the bottom opening of the connecting sleeve is set in a downward and outward expansion shape. When the plug rod and the connecting sleeve are inserted and mated, the guide rod and the connecting sleeve can be smoothly inserted and mated, without the need for the operator to accurately align the axis of the connecting sleeve and the plug rod, thus improving the installation efficiency of the insertion and mating of the connecting sleeve and the plug rod.

[0015] Preferably, a fastening bolt is provided through the inner wall of the middle part of the slider, and the slider and the slide groove are fixedly connected by the fastening bolt.

[0016] By adopting the above technical solution, the fastening bolts inserted through the inner wall of the middle of the slider can fix the slider to the slide groove. After adjusting the position of the slider in the slide groove according to the support requirements, tightening the fastening bolts can make the slider and the slide groove fit tightly, restricting the slider from sliding in the slide groove. When the supporting keel bears the pressure of the top plate formwork and transmits it to the slider, the fastening bolts can effectively resist the sliding tendency of the slider, prevent the slider from shifting due to force, and ensure that the support position of the connecting sleeve, plug rod and support column remains fixed, further ensuring the overall stability of the support system.

[0017] Preferably, through mounting grooves are provided on both sides of the slide groove, the mounting grooves are positioned to correspond to the positions of the fastening bolts, and both ends of the fastening bolts extend to the outside of the slide groove through the mounting grooves.

[0018] By adopting the above technical solution, the mounting grooves on both sides of the slide correspond to the positions of the fastening bolts, and the two ends of the fastening bolts extend to the outside of the slide through the mounting grooves. The mounting grooves provide moving space for the fastening bolts, so that when the slider slides and adjusts its position in the slide, the fastening bolts can move synchronously along the mounting grooves, thus avoiding the fastening bolts from obstructing the sliding of the slider.

[0019] Preferably, two connecting washers are fitted on the outer surfaces of both ends of the fastening bolt, and the two connecting washers are located on both sides outside the slide groove, and the diameter of the connecting washers is greater than the height inside the mounting groove.

[0020] By adopting the above technical solution, the two connecting washers fitted on the outer surfaces of both ends of the fastening bolt are located on both sides of the outside of the slide groove, and the diameter of the connecting washers is greater than the height inside the mounting groove. When the fastening bolt is tightened, the connecting washers can increase the contact area between the fastening bolt and the outer wall of the slide groove, improve the fixing effect between the slider and the slide groove, and ensure the stability of the fastening bolt in fixing the slider in the position inside the slide groove.

[0021] In summary, this application includes at least one of the following beneficial technical effects: This roof slab formwork support system structure, through the tight insertion and connection of the plug rod and the connecting sleeve, can fix the angle between the support pole and the load-bearing keel, so that the support pole always maintains a vertical support state with the load-bearing keel after supporting it. This achieves stable support of the support pole to the load-bearing keel, effectively preventing relative tilting between the support pole and the load-bearing keel when the support pole is under pressure, and improving the stability of the roof slab formwork support by keeping the support pole in a vertical support state with the load-bearing keel at all times.

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0025] Example 1: A roof slab formwork support system structure, please refer to... Figure 1 , Figure 2 and Figure 4 The system includes a supporting keel 1, a connecting component 2 at the bottom of the supporting keel 1, a sliding groove 201, a plurality of sliders 202 slidingly disposed inside the sliding groove 201, a connecting sleeve 3 fixedly disposed at the bottom of the sliders 202, a plug rod 4 inserted into the inner wall of the middle part of the connecting sleeve 3, the specifications of the outer surface of the middle part of the plug rod 4 being adapted to the specifications of the inner wall of the middle part of the connecting sleeve 3, the plug rod 4 being fixedly disposed at the top of the supporting upright 5, and an adjusting component 6 disposed at the bottom of the supporting upright 5, the adjusting component 6 being disposed at the top of the supporting base plate 7.

[0026] Please see Figure 2 , Figure 3 and Figure 4 A guide cover 10 is fixedly installed at the bottom opening of the connecting sleeve 3. The guide cover 10 is set in a downward and outward shape. When the plug rod 4 and the connecting sleeve 3 are plugged in, the guide cover 10 can guide the plug rod 4 and the connecting sleeve 3 to be plugged in smoothly. The operator does not need to accurately align the axis of the connecting sleeve 3 and the plug rod 4, which improves the installation efficiency of the plugging and mating of the connecting sleeve 3 and the plug rod 4.

[0027] Please see Figure 1 , Figure 2 and Figure 3A fastening bolt 12 is provided through the inner wall of the middle part of the slider 202. The slider 202 and the slide groove 201 are fixedly connected by the fastening bolt 12. The fastening bolt 12 through the inner wall of the middle part of the slider 202 can fix the slider 202 and the slide groove 201. After adjusting the position of the slider 202 in the slide groove 201 according to the support requirements, tightening the fastening bolt 12 can make the slider 202 and the slide groove 201 fit tightly, restricting the sliding of the slider 202 in the slide groove 201. When the supporting keel 1 bears the pressure of the top plate template and transmits it to the slider 202, the fastening bolt 12 can effectively resist the sliding tendency of the slider 202, prevent the slider 202 from shifting due to force, and ensure that the support position of the connecting sleeve 3, the plug rod 4 and the support column 5 remains fixed, further ensuring the overall stability of the support system.

[0028] Please see Figure 1 , Figure 2 and Figure 3 The slide groove 201 has through mounting grooves 11 on both sides. The mounting grooves 11 are located in positions corresponding to the fastening bolts 12. Both ends of the fastening bolts 12 extend to the outside of the slide groove 201 through the mounting grooves 11. The mounting grooves 11 on both sides of the slide groove 201 correspond to the positions of the fastening bolts 12, and both ends of the fastening bolts 12 extend to the outside of the slide groove 201 through the mounting grooves 11. The mounting grooves 11 provide moving space for the fastening bolts 12, so that when the slider 202 slides and adjusts its position in the slide groove 201, the fastening bolts 12 can move synchronously along the mounting grooves 11, avoiding the fastening bolts 12 from obstructing the sliding of the slider 202.

[0029] Please see Figure 1 , Figure 2 and Figure 3 Two connecting washers 13 are fitted on the outer surfaces of both ends of the fastening bolt 12. The two connecting washers 13 are located on both sides of the outside of the slide groove 201. The diameter of the connecting washers 13 is greater than the height inside the mounting groove 11. When the fastening bolt 12 is tightened, the connecting washers 13 can increase the contact area between the fastening bolt 12 and the outer wall of the slide groove 201, improve the fixing effect between the slider 202 and the slide groove 201, and ensure the stability of the fastening bolt 12 in fixing the slider 202 in the position inside the slide groove 201.

[0030] Example 2: A roof slab formwork support system structure, please refer to... Figure 1 , Figure 2 and Figure 4The adjusting component 6 includes a threaded rod 601, which is fixedly installed at the bottom end of the supporting pole 5. The outer surface of the middle part of the threaded rod 601 is threadedly connected to the inner wall of the middle part of the threaded sleeve 602. The bottom end of the threaded sleeve 602 is rotatably installed at the top of the supporting base plate 7. The threaded rod 601 in the adjusting component 6 is fixedly connected to the supporting pole 5, and the threaded sleeve 602 is threadedly engaged with the threaded rod 601. The bottom end of the threaded sleeve 602 is rotatably installed at the top of the supporting base plate 7. When the threaded sleeve 602 is rotated, the threaded rod 601 can move up and down along the axial direction of the threaded sleeve 602 using the thread transmission principle, thereby driving the supporting pole 5 to rise and fall synchronously, realizing precise adjustment of the height of the supporting pole 5 to adapt to the support requirements of the top plate template of different heights. Furthermore, the adjusting component 6 is located at the bottom end of the supporting pole 5, which allows for convenient adjustment of the height of the supporting pole 5 from below without the need for a climbing frame, thus improving the safety of adjusting the supporting pole 5.

[0031] Please see Figure 1 , Figure 2 and Figure 3 A worm gear 603 is fixedly mounted on the outer surface of the middle part of the threaded sleeve 602. The worm gear 603 meshes with the worm 604. The outer surfaces of both ends of the worm 604 are rotatably mounted on the top of the support base plate 7 via a support frame. A screwing head 14 is fixedly mounted at the end of the worm 604. The worm gear 603 on the outer surface of the threaded sleeve 602 meshes with the worm 604. The worm 604 is rotatably mounted on the top of the support base plate 7 via a support frame. The screwing head 14 at the end facilitates the operator to rotate the worm 604. When the screwing head 14 is rotated, the worm 604 drives the worm gear 603 to rotate, thereby driving the worm gear 604 to rotate. The threaded sleeve 602 rotates synchronously to adjust the height of the support rod 5. The height of the support rod 5 can be precisely adjusted through the cooperation of the worm gear 603 and the worm 604. Furthermore, the self-locking performance of the worm gear 603 and the worm 604 effectively prevents the threaded sleeve 602 from rotating on its own due to the pressure of the support rod 5 after adjustment, ensuring that the height of the support rod 5 remains stable. This avoids the situation where the connecting sleeve 3 and the plug rod 4 separate due to changes in the support height caused by accidental rotation of the threaded sleeve 602, further improving the reliability of the support system.

[0032] Please see Figure 4 and Figure 5A limiting hole 9 is provided at the bottom end of the support rod 5. The limiting hole 9 extends downward and penetrates the middle inner wall of the threaded rod 601. A limiting rod 8 is inserted into the inner wall of the limiting hole 9. The bottom end of the limiting rod 8 is fixedly set at the top of the support base plate 7. The shape of the middle outer surface of the limiting rod 8 is polygonal. The shape of the middle outer surface of the limiting rod 8 matches the shape of the inner wall of the limiting hole 9. The limiting hole 9 at the bottom end of the support rod 5 and the limiting rod 8 at the top of the support base plate 7 are inserted and matched. The middle outer surface of the limiting rod 8 is polygonal and matches the shape of the inner wall of the limiting hole 9, which can limit the relative rotation between the support rod 5 and the limiting rod 8. When the height of the support rod 5 is adjusted by the adjusting component 6, the support rod 5 can only move up and down along the axial direction of the limiting rod 8 and will not rotate circumferentially. This allows the threaded sleeve 602 to stably drive the support rod 5 to adjust its height when rotating.

[0033] The implementation principle of this application embodiment is as follows: The supporting base plate 7 is placed at a preset supporting position, so that the positions of multiple supporting uprights 5 correspond to the preset supporting positions. According to the support requirements of the top plate template, the slider 202 is pushed to slide within the slide groove 201, and the position of the connecting sleeve 3 is adjusted so that the position of the connecting sleeve 3 corresponds to the preset support point. After the position of the slider 202 is adjusted, the position between the slider 202 and the slide groove 201 is fixed using fastening bolts 12 and connecting washers 13. Through the guide cover 10 at the bottom of the connecting sleeve 3, the insertion rod 4 is guided to insert into the connecting sleeve 3, so that the insertion rod 4 is inserted into the inner wall of the connecting sleeve 3. The insertion of the connecting sleeve 3 establishes a preliminary connection and positioning between the supporting upright 5 and the load-bearing keel 1. Based on the required support height of the top slab template, the tool is used to operate the screw head 14 to rotate, driving the worm gear 604 to rotate. The worm gear 604 drives the worm wheel 603 to rotate, which in turn drives the threaded sleeve 602 to rotate. Through the threaded connection between the threaded sleeve 602 and the threaded rod 601, and in conjunction with the insertion of the polygonal limiting rod 8 and the limiting hole 9, the threaded sleeve 602 drives the threaded rod 601 to move upward, thereby moving the supporting upright 5 upward. Based on the required support height of the top slab template, the support height of the supporting upright 5 on the load-bearing keel 1 is adjusted to adapt to the support height of the template.
