Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to an adjustable and easily detachable formwork support. Background Technology

[0002] Before concrete pouring, concrete formwork needs to be erected. When pouring floor slabs, formwork supports need to be erected first. After the formwork supports are erected, the concrete formwork will be laid on the formwork supports so that the formwork supports can support and support the concrete formwork and the concrete poured on the formwork.

[0003] When constructing a formwork support system, there will be certain dimensional tolerances between the individual uprights, especially when the uprights are composed of multiple connected uprights. This dimensional error will be greater, causing the upper surfaces of the uprights in the constructed formwork support system to be at different vertical heights, which can easily lead to uneven concrete formwork. In addition, when the overall size of the formwork support system is large, it is often necessary to extend the members. In order to ensure the structural strength of the extended members, fasteners are needed to connect the joints. However, existing fasteners are generally installed by first aligning the members and then installing the fasteners, which is inefficient and makes the installation process inefficient.

[0004] Therefore, there is a need for an adjustable and easily detachable template support. Summary of the Invention

[0005] To address the issues of uneven concrete formwork laying caused by the upper surfaces of the columns not being at the same vertical height, and the inconvenience of installation and overlapping operations, this application provides an adjustable and easily disassembled formwork support.

[0006] This application provides an adjustable and easily detachable template support, employing the following technical solution: An adjustable and easily detachable template support includes an upright assembly, horizontal bars, and a connecting assembly. The upright assembly includes an upright body and an adjustable support. The connecting assembly includes quick-connect extension buckles and horizontal and vertical connecting buckles. Adjacent upright bodies and adjacent horizontal bars can be aligned and connected via the quick-connect extension buckles, and the horizontal bars can be connected to the upright bodies via the horizontal and vertical connecting buckles. The adjustable support includes an adjusting screw and a support plate. The adjusting screw is rotatably connected to the upright body, and the support plate is provided at one end of the adjusting screw away from the upright body, so that the vertical height of the support plate can be adjusted by rotating the adjusting screw.

[0007] By adopting the above technical solution, the vertical height of the support plate can be adjusted by rotating the adjusting screw, which makes the concrete formwork laid on the support plate more flat, and thus makes the poured floor slab or roof more flat. In addition, during the installation and overlapping of the formwork support, if the length of the rod is insufficient and needs to be extended, the quick-connect coupling can be used to assist in alignment, which facilitates the overlapping installation and improves the efficiency of the overlapping installation.

[0008] Furthermore, the end of the upright rod connected to the adjusting screw is provided with a sleeve structure. The sleeve structure has an internal thread structure that matches the adjusting screw, and a pair of sleeve grooves extending axially along the sleeve structure are formed inside the sleeve structure. The two sleeve grooves are equally spaced along the circumferential direction of the inner wall of the sleeve structure, and a sleeve protrusion is formed on the inner wall of the sleeve structure between the two sleeve grooves. The sleeve protrusion has the internal thread structure. The adjusting screw has a screw protrusion that matches the sleeve groove, and the screw protrusion has an external thread structure.

[0009] By adopting the above technical solution, the adjustment accuracy of the adjustable support can be improved by using a screw adjustment method. When the adjusting screw is rotated until the screw protrusion is in the sleeve groove, the adjusting screw can move quickly in the sleeve structure, so as to realize the rapid adjustment of the adjustable support. After the adjustment is in place, the adjusting screw is rotated until the external thread structure on the screw protrusion and the internal thread structure on the sleeve protrusion cooperate to realize the self-locking connection between the adjusting screw and the sleeve structure.

[0010] Furthermore, the adjustable support also includes a limiting ring, which may be provided with a through hole suitable for the adjusting screw to pass through, so as to be sleeved on the adjusting screw and move along the adjusting screw. The through hole is provided with a plug-in block that matches the sleeve groove, and the plug-in block can be inserted into the sleeve groove.

[0011] By adopting the above technical solution, when the adjusting screw rotates to the point where the external thread structure on the screw protrusion engages with the internal thread structure on the sleeve protrusion, the plug block can be inserted into the sleeve groove to prevent the adjusting screw from rotating, thereby preventing the connection between the adjusting screw and the sleeve structure from failing.

[0012] Furthermore, the outer circumferential surface of the end of the upright pole is provided with multiple upright pole limiting grooves. The multiple upright pole limiting grooves extend along the axial direction of the upright pole and are arranged at equal intervals along the circumference of the upright pole. A tensile surface of the upright pole is formed near the end of the upright pole in each of the upright pole limiting grooves. The outer circumferential surface of the end of the crossbar is provided with multiple crossbar limiting grooves. The multiple crossbar limiting grooves extend along the axial direction of the crossbar and are arranged at equal intervals along the circumference of the crossbar. A tensile surface of the crossbar is formed near the end of the crossbar in each of the crossbar limiting grooves.

[0013] By adopting the above technical solutions, the horizontal bar tensile surface ensures that the horizontal bar is not easily detached from the quick-connect coupling after being extended, and the horizontal bar limiting groove design prevents relative rotation between the horizontal bar and the quick-connect coupling after connection, thereby improving the stability of the lapped formwork support. Similarly, the vertical bar tensile surface ensures that the vertical bar is not easily detached from the quick-connect coupling after being extended, and the vertical bar limiting groove design prevents relative rotation between the vertical bar and the quick-connect coupling after connection, thereby improving the stability of the lapped formwork support.

[0014] Furthermore, the extension quick-connect buckle includes two fastening plates and a hinge shaft. Both fastening plates are hinged to the hinge shaft, and the two fastening plates can be fastened and locked to form a connecting sleeve. The connecting sleeve includes a fixed connecting section and a quick-connecting section. After the two fastening plates are fastened and locked, the fixed connecting section can be fixedly connected to the upright or the crossbar. The quick-connecting section is provided with a movable locking member, so that when the movable locking member is in the open state, the quick-connecting section can be sleeved on another corresponding upright or the crossbar, and when the movable locking member is in the locked state, the quick-connecting section can be fixedly connected to another corresponding upright or the crossbar.

[0015] By adopting the above technical solution, the quick-connect buckle can be fastened to one pole first, and the connecting sleeve formed after the two fastening plates are fastened and locked can be fitted onto another pole to play an auxiliary alignment role. Especially when extending the pole, the upper pole body can be inserted into the lower pole body through the connecting sleeve, so that hands can be freed to perform subsequent fastening operations, making the extension process more convenient.

[0016] Furthermore, both of the fastening plates are provided with plate connecting ears, and the two plate connecting ears are provided with connecting holes, so that bolts can pass through the two connecting holes and be connected with nuts to achieve the fastening and locking of the two fastening plates.

[0017] By adopting the above technical solution, the two fastening plates can be locked together by screw connection.

[0018] Furthermore, each of the two fastening plates has a limiting protrusion on the inner wall of the fixed connection section. The limiting protrusion can cooperate with the vertical pole limiting groove or the horizontal bar limiting groove, and the end of the limiting protrusion has a protrusion contact surface that can abut against the tensile surface of the vertical pole or the tensile surface of the horizontal bar.

[0019] By adopting the above technical solution, the contact between the protruding abutment surface and the tensile surface of the upright or horizontal bar can prevent the upright or horizontal bar from coming out of the extension quick-connect buckle.

[0020] Furthermore, the outer walls of the quick-connect section of both fastening plates are provided with multiple hinge seats, clearance slots and multiple rotating rods. One end of each rotating rod is hinged to the hinge seat, and the rotating rod is provided with a limiting protrusion on the side facing the clearance slot. The limiting protrusion can pass through the clearance slot to cooperate with the vertical pole limiting slot or the horizontal pole limiting slot, and the two ends of the limiting protrusion form protrusion abutment surfaces.

[0021] The outer walls of the two fastening plates belonging to the quick-connect section are also provided with a gathering ring, and the multiple rotating rods are gathered and locked by the gathering ring.

[0022] By adopting the above technical solution, when multiple rotating rods are not constrained by the retaining ring, the rotating rods can deflect away from the direction of the clearance groove, so that the rods can be freely inserted into the quick-connect section of the connecting sleeve, or pulled out from the quick-connect section, so as to facilitate installation and disassembly.

[0023] Furthermore, the retaining ring includes a first half-ring and a second half-ring, which are hinged together via the hinge axis. The first half-ring has a first half-ring connecting lug on its side away from the hinge axis, and a connecting hole suitable for a bolt to pass through is formed in the first half-ring connecting lug. The second half-ring has a second half-ring connecting lug on its side away from the hinge axis, and a connecting hole suitable for a bolt to pass through is formed in the second half-ring connecting lug, so that the bolt can pass through the connecting hole and be connected to the nut to achieve the locking of the first half-ring and the second half-ring.

[0024] By adopting the above technical solution, the locking and fastening between the first half ring and the second half ring can be achieved by screwing them together.

[0025] Furthermore, the pole assembly also includes a base, which is connected to the pole body, and the side of the base that contacts the ground is provided with an anti-slip layer.

[0026] By adopting the above technical solution, setting a base can increase the contact area between the upright and the ground, thereby making the end of the upright that is in contact with the ground less prone to damage. In addition, setting an anti-slip layer can increase the friction between the upright and the ground, so that the erected formwork support is less likely to slip.

[0027] In summary, this application includes at least one of the following beneficial effects:

[0028] 1. The vertical height of the support plate can be adjusted by rotating the adjusting screw, so that the concrete formwork laid on the support plate can be flatter, and thus the poured floor slab or roof can be flatter.

[0029] 2. Furthermore, during the installation and overlapping of the template support, if the length of the rod is insufficient and needs to be extended, quick-connect couplings can be used to assist in alignment, thereby facilitating the overlapping installation and improving the efficiency of the overlapping installation.

[0042] Figure 1 This is a perspective view of an adjustable and easily detachable template support according to this application. See also: Figure 1 The adjustable and easily detachable template support provided in this application includes an upright assembly, a horizontal bar 1, and a connecting assembly. The upright assembly includes an upright body 2 and an adjustable support 3. The connecting assembly includes an extension quick-connect buckle 4 and a horizontal and vertical connecting buckle 5. Adjacent upright bodies 2 and adjacent horizontal bars 1 can be aligned and connected via the extension quick-connect buckle 4, and the horizontal bar 1 can be connected to the upright body 2 via the horizontal and vertical connecting buckle 5.

[0043] Figure 2 This is a schematic diagram showing the connection between the adjustable support and the upright in an adjustable and easily detachable formwork support according to this application. See also... Figure 2 The adjustable support 3 includes an adjusting screw 31 and a support plate 32. The adjusting screw 31 is rotatably connected to the upright 2, and the end of the adjusting screw 31 away from the upright 2 is provided with a support plate 32. The vertical height of the support plate 32 can be adjusted by rotating the adjusting screw 31, so that the concrete formwork laid on the support plate 32 can be flatter, and the poured floor slab or roof can be flatter.

[0044] During the installation and overlapping of the formwork support, if the length of the rod is insufficient and needs to be extended, the quick-connect buckle 4 can be used to assist in alignment, thereby facilitating the overlapping installation and improving the efficiency of the overlapping installation. In addition, the horizontal bar 1 can be connected to the vertical bar 2 through the horizontal and vertical connecting buckle 5, so that the vertical bar 2 and the horizontal bar 1 can form a formwork support composed of multiple cubic frame structures. The horizontal and vertical connecting buckle 5 is a steel pipe buckle, which is existing technology and will not be described in detail here.

[0045] Figure 3 yes Figure 2 Sectional view in the CC direction, Figure 4 yes Figure 3 A cross-sectional view along the DD direction, such as Figure 3 and Figure 4 As shown, the end of the upright stalk 2 connected to the adjusting screw 31 is provided with a sleeve structure 21. The adjusting screw 31 is provided with an external thread structure. The sleeve structure 21 is provided with an internal thread structure that matches the adjusting screw 31. A pair of sleeve grooves 211 extending axially along the sleeve structure 21 are provided in the sleeve structure 21. The two sleeve grooves 211 are equally spaced along the circumferential direction of the inner wall of the sleeve structure 21. A sleeve protrusion is formed on the inner wall of the sleeve structure 21 between the two sleeve grooves 211. The sleeve protrusion is provided with an internal thread structure. The adjusting screw 31 is provided with a screw protrusion 311 that matches the sleeve groove 211. The screw protrusion 311 is provided with an external thread structure.

[0046] Using a screw adjustment method allows for higher adjustment precision of the adjustable support 3. When the adjusting screw 31 is rotated until the screw protrusion 311 is in the sleeve groove 211, the adjusting screw 31 can move quickly within the sleeve structure 21, enabling rapid adjustment of the adjustable support 3. After adjustment, the adjusting screw 31 is rotated until the external thread on the screw protrusion 311 engages with the internal thread on the sleeve protrusion, thus achieving a self-locking connection between the adjusting screw 31 and the sleeve structure 21.

[0047] like Figure 3 and Figure 4 As shown, the adjustable support 3 can also be provided with a limiting ring 33. Specifically, the limiting ring 33 can be provided with a through hole suitable for the adjusting screw 31 to pass through, so that the limiting ring 33 can be sleeved on the adjusting screw 31 and move along the adjusting screw 31. The through hole is provided with a plug block 331 that matches the sleeve groove 211, and the plug block 331 can be inserted into the sleeve groove 211. When the adjusting screw 31 rotates to the point where the external thread structure on the screw protrusion 311 engages with the internal thread structure on the sleeve protrusion, the plug block 331 can be inserted into the sleeve groove 211 to prevent the adjusting screw 31 from rotating, thereby preventing the connection between the adjusting screw 31 and the sleeve structure 21 from failing.

[0048] Figure 5 yes Figure 1 Enlarged view of region A in the middle. Figure 6 This is a front view of an adjustable and easily detachable template support frame according to this application, specifically an extension quick-connect buckle. Figure 5 and Figure 6 As shown, the extension quick-connect buckle 4 can be configured to include two fastening plates 41 and a hinge shaft 42. Taking the crossbar 1 and the upright bar 2 as round bars as an example, both fastening plates 41 are arc-shaped plates and are hinged to the hinge shaft 42, so that after the two fastening plates 41 are fastened and locked, a connecting sleeve structure can be formed. The connecting sleeve includes a fixed connecting section and a quick-connect fastening section. After the two fastening plates 41 are fastened and locked, the fixed connecting section can be fixedly connected to the upright bar 2 or the crossbar 1. The quick-connect fastening section is provided with a movable locking member, so that when the movable locking member is in the open state, the quick-connect fastening section can be sleeved on another corresponding upright bar 2 or the crossbar 1, and when the movable locking member is in the locked state, the quick-connect fastening section can be fixedly connected to another corresponding upright bar 2 or the crossbar 1.

[0049] The design of the aforementioned quick-connect buckle 4, taking the connection of two upright poles 2 as an example, allows the quick-connect buckle 4 to be fastened to the upper upright pole 2 before connection. At this time, the fixed connection section of the quick-connect buckle 4 is connected to the upper upright pole 2, and the quick-connect section of the quick-connect buckle 4 has an insertion cavity suitable for the lower upright pole 2 to be inserted. This allows the quick-connect section to play an auxiliary alignment role and a temporary connection role, freeing up hands to perform the subsequent fastening operation of the movable locking parts, making the extension process (especially the extension process of the upright pole 2) more convenient.

[0050] Specifically, plate connecting ears 411 can be provided on both fastening plates 41. The two plate connecting ears 411 are provided with connecting holes so that bolts can pass through the two connecting holes and be connected with nuts to realize the fastening and locking of the two fastening plates 41. In addition, washers can be provided between the nuts and connecting ears to prevent relative sliding between the nuts and the abutting surfaces, which would cause the fastening and locking to fail.

[0051] Figure 7 yes Figure 6 Sectional view along the EE direction. Figure 8 yes Figure 6 A cross-sectional view along the FF direction, such as Figure 7 and Figure 8As shown, multiple pole limiting grooves 22 can be provided on the outer circumferential surface of the end of the pole body 2. The multiple pole limiting grooves 22 extend along the axial direction of the pole body 2 and are arranged at equal intervals along the circumference of the pole body 2. A pole tensile surface 221 is formed at the end of each pole limiting groove 22 near the end of the pole body 2. In addition, multiple crossbar limiting grooves 11 are also provided on the outer circumferential surface of the end of the crossbar 1. The multiple crossbar limiting grooves 11 extend along the axial direction of the crossbar 1 and are arranged at equal intervals along the circumference of the crossbar 1. A crossbar tensile surface 111 is formed at the end of each crossbar limiting groove 11 near the end of the crossbar 1.

[0052] like Figure 7 As shown, based on the above-mentioned configuration of the upright pole 2 and the horizontal bar 1, the inner walls of the fixed connection sections of the two fastening plates 41 are provided with limiting protrusions 43. When the two fastening plates 41 are fastened and locked, the limiting protrusions 43 can be inserted into the upright limiting groove 22 or the horizontal bar limiting groove 11, so that after the horizontal bar 1 is connected to the extension quick-connect buckle 4 or after the upright pole 2 is connected to the extension quick-connect buckle 4, the pole and the extension quick-connect buckle 4 are not prone to relative rotation, thereby improving the stability of the template support after the overlap.

[0053] Figure 9 yes Figure 8 A cross-sectional view along the GG direction, showing the structure at the joint of the upright. Figure 10 yes Figure 8 A cross-sectional view along the GG direction shows the structure at the point where the crossbar is extended, such as... Figure 9 and Figure 10 As shown, the end of the limiting protrusion 43 is formed with a protrusion abutment surface that can abut against the tensile surface 221 of the upright or the tensile surface 111 of the crossbar, so that the upright body 2 can abut against the protrusion abutment surface via the tensile surface 221 of the upright and the crossbar 1 can abut against the protrusion abutment surface via the tensile surface 111 of the crossbar. This makes it difficult for the upright body 2 or the crossbar 1 to come out of the extension quick-connect buckle 4, thus ensuring the stability of the lapped template support.

[0054] like Figure 5 and Figure 8 As shown, the outer walls of the quick-connect section of the two fastening plates 41 are provided with hinge seats 44, clearance slots 45 and multiple rotating rods 46. One end of each rotating rod 46 is hinged to the hinge seat 44, and a limiting protrusion 461 is provided on the side of the rotating rod 46 facing the clearance slot 45. The limiting protrusion 461 can pass through the clearance slot 45 to cooperate with the vertical pole limiting slot 22 or the horizontal bar limiting slot 11, and the two ends of the limiting protrusion 461 form protrusion abutment surfaces. The outer walls of the quick-connect section of the two fastening plates 41 are also provided with a tightening ring, and the multiple rotating rods 46 are tightened and locked by the tightening ring.

[0055] When the multiple rotating rods 46 are not constrained by the retaining ring, the rotating rods 46 can deflect away from the clearance slot 45, so that the rods can be freely inserted into or pulled out of the quick-connect section of the connecting sleeve, facilitating installation and disassembly. When the retaining ring is locked, the multiple rotating rods 46 will rotate towards the clearance slot 45 under the abutment of the retaining ring, and the limiting protrusions 461 on each rotating rod 46 can pass through the clearance slot 45 and be inserted into the upright limiting slot 22 or... In the horizontal bar limiting groove 11, the quick-connect section on the extension quick-connect buckle 4 can be fixedly connected to the rod, and the rod and the extension quick-connect buckle 4 are not prone to relative rotation, thereby ensuring the stability of the connection; in addition, the upright rod 2 can abut against the protruding edge abutting surface through the upright tensile surface 221, and the horizontal bar 1 can abut against the protruding edge abutting surface through the horizontal bar tensile surface 111, thereby making it difficult for the upright rod 2 or the horizontal bar 1 to come out of the extension quick-connect buckle 4, thus ensuring the stability of the lapped template support.

[0056] like Figure 6 and Figure 7 As shown, the snap ring can be specifically configured to include a first half-ring 471 and a second half-ring 472. The first half-ring 471 and the second half-ring 472 are hinged via a hinge shaft 42. The first half-ring 471 has a first half-ring connecting ear 4711 on its side away from the hinge shaft 42, and a connecting hole suitable for a bolt to pass through is formed in the first half-ring connecting ear 4711. The second half-ring 472 has a second half-ring connecting ear 4721 on its side away from the hinge shaft 42, and a connecting hole suitable for a bolt to pass through is formed in the second half-ring connecting ear 4721, so that the bolt can pass through the connecting hole and be connected with a nut to achieve the locking of the first half-ring 471 and the second half-ring 472.

[0057] Figure 11 yes Figure 1 A magnified view of region B in the middle, as shown below. Figure 11 As shown, the upright assembly also includes a base 6, which is connected to the upright body 2. The side of the base 6 that contacts the ground is provided with a rubber anti-slip layer 61. The base 6 increases the contact area between the upright body 2 and the ground, making the end of the upright body 2 that contacts the ground less prone to damage. The anti-slip layer 61 also increases the friction between the upright body 2 and the ground, making the erected template support less prone to slippage.

[0058] The working principle of the adjustable and easily detachable template support in this application is as follows:

[0059] By rotating the adjusting screw 31 to adjust the vertical height of the support plate 32, the concrete formwork laid on the support plate 32 can be made flatter, thereby making the poured floor slab or roof flatter.

[0060] During the installation and splicing of the template support, if the length of the pole is insufficient and needs to be extended, the fixed connection section of the extension quick-connect buckle 4 can be fastened to the pole first, so that the fixed connection section is fixedly connected to the pole. Then, the quick-connecting section of the extension quick-connect buckle 4, which forms a sleeve structure 21, can play a role in assisting alignment and temporary connection, so that it is convenient to free up hands to perform the subsequent fastening operation of the movable locking parts, making the extension process (especially the extension process of the upright pole 2) more convenient and improving the efficiency of the splicing installation.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
