[0002] At the construction site, before pouring reinforced concrete, it is necessary to build a building formwork first, splice multiple building formworks to form the required structural form, and use pillars to support the building formwork to avoid deformation or collapse when pouring concrete. The pillars and building formwork are removed when the concrete reaches the final setting age. The early removal formwork is a support device used to achieve early removal of the floor formwork. Its working principle is "removing the slab but not the column". When the concrete strength reaches the early removal strength, the floor formwork and part of the support device can be removed, leaving a part of the support device to continue supporting until the concrete strength reaches the design requirements and then all are removed.

[0003] However, there is slippage between the existing early-dismantling formwork and the supporting device, resulting in unstable support and a relatively low safety factor. Utility Model Content

[0038] like Figures 1 to 3 As shown, the template early disassembly device provided in this embodiment includes a template assembly 1, a connecting supporting structure 2, a connecting supporting structure 2, a cross bar 3 and a column 4, the template assembly 1 includes a main template 12 and a rear disassembly template 13, the main template 12 and the rear disassembly template 13 are detachably connected; the connecting supporting structure 2 is detachably installed on the rear disassembly template 13; the cross bar 3 is detachably installed on the connecting supporting structure 2, and the cross bar 3 is used to support the main template 12; the column 4 is installed at the bottom of the connecting supporting structure 2, and the column 4 is used to support the connecting supporting structure 2.

[0039] This embodiment utilizes the connecting supporting structure 2 to support the rear-removal formwork 13, and utilizes the cross bar 3 to support the main formwork 12, so as to improve the safety and stability coefficient of the formwork support system. When the concrete strength reaches the early-removal strength, the cross bar 3 is removed from the connecting supporting structure 2, and the main formwork 12 is removed, while the rear-removal formwork 13, the connecting supporting structure 2 and the column 4 are retained, so as to improve the installation and removal efficiency of the formwork early-removal system, until the concrete strength reaches the design requirements, the rear-removal formwork 13, the connecting supporting structure 2 and the column 4 are all removed.

[0040] In this embodiment, the main template 12 is detachably installed with rear disassembly templates 13 at both ends in the Y-axis direction, and a connecting supporting structure 2 is installed at the bottom of each rear disassembly template 13. The two corresponding connecting supporting structures 2 in the Y-axis direction jointly support the cross bar 3.

[0041] The area of ​​the main formwork 12 is much larger than the area of ​​the post-removal formwork 13. When pouring concrete, the main formwork 12 carries much more concrete than the post-removal formwork 13. When the concrete strength reaches the early-removal strength but has not reached the full-removal strength, the main formwork 12 can be removed first, and the removed main formwork 12 can continue to be used in other concrete pouring sites, thereby improving the use efficiency of the main formwork 12. In the early stage of concrete pouring, in order to improve the safety of the main formwork 12, this embodiment uses two connecting supporting structures 2 to support the cross bar 3, so that the cross bar 3 can stably support the main formwork 12.

[0042] In some other embodiments, a rear disassembly template 13 is provided at one end of the main template 12 in the Y-axis direction, and a slot is provided at the other end of the main template 12 in the Y-axis direction. One end of the cross bar 3 is inserted into the slot, and the other end of the cross bar 3 is supported by the connecting support structure 2.

[0043] Optionally, a receiving groove 11 extending along the X-axis direction is provided at the bottom of the rear disassembly template 13 , and the connecting supporting structure 2 is embedded in the receiving groove 11 .

[0044] The connecting support structure 2 is embedded in the receiving groove 11 extending along the X-axis direction to prevent the connecting support structure 2 from being subjected to external force, so as to ensure the connection stability between the connecting support structure 2 and the template assembly 1; the receiving groove 11 extends along the X-axis direction and has a limiting effect on the slippage of the connecting support structure 2 along the Y-axis direction.

[0045] Optionally, the early template removal device includes a locking assembly 5, the side wall of the accommodating groove 11 is provided with a first connecting hole, the connecting supporting structure 2 is provided with a second connecting hole, and the locking assembly 5 passes through the first connecting hole and the second connecting hole to lock the connecting supporting structure 2 to the accommodating groove 11.

[0046] In this embodiment, the main template 12 and the rear disassembly template 13 are both provided with connecting holes, and the connecting holes of the main template 12 are aligned one by one with the connecting holes of the rear disassembly template 13. The locking components 5 can pass through the connecting holes of the main template 12 and the connecting holes of the rear disassembly template 13, thereby locking and fixing the main template 12 and the rear disassembly template 13 to prevent relative slippage between the two. Other locking components 5 pass through the connecting holes of the main template 12, the connecting holes of the rear disassembly template 13 and the second connecting holes of the connecting supporting structure 2, thereby locking and fixing the main template 12, the rear disassembly template 13 and the connecting supporting structure 2 to prevent the connecting supporting structure 2 from sliding along the X-axis direction in the accommodating groove 11 of the rear disassembly template 13.

[0047] In this embodiment, the locking assembly 5 includes a bolt member and a nut member.

[0048] In this embodiment, the connecting plate 21 includes a connecting wall 211 and a supporting wall 212. The connecting wall 211 is provided with a second connecting hole. The locking assembly 5 passes through the first connecting hole and the second connecting hole to lock and fix the connecting plate 21 to the template assembly 1. The supporting member 221 and the connecting member 222 are both connected to one end of the supporting wall 212 extending out of the accommodating groove 11, reserving an installation position for the cross bar 3.

[0049] Optionally, the early template removal device includes several groups of template assemblies 1 arranged in sequence along the X-axis direction, and a connecting supporting structure 2 is installed between two adjacent groups of template assemblies 1. The connecting supporting structure 2 can be fixedly connected to the two adjacent groups of template assemblies 1 through a locking assembly 5.

[0050] The number of formwork assemblies 1 can be set according to actual needs. For example, the larger the construction site area, the more formwork assemblies 1 are used. The connecting supporting structure 2 can support one group of formwork assemblies 1, and can also support two adjacent groups of formwork assemblies 1 at the same time. The two adjacent groups of formwork assemblies 1 are fixedly connected to the same connecting supporting structure 2 through locking assemblies 5 to prevent the two adjacent groups of formwork assemblies 1 from relative slipping.

[0051] Optionally, the connecting supporting structure 2 includes a connecting plate 21 and a supporting assembly 22, the column 4 is installed at the bottom of the connecting plate 21, the supporting assembly 22 includes a supporting member 221, a connecting member 222 and a locking member, one end of the supporting member 221 is movably connected to the connecting plate 21, and the other end of the supporting member 221 is provided with an avoidance groove; one end of the connecting member 222 is movably connected to the connecting plate 21, and the other end of the connecting member 222 can slide into the avoidance groove; the locking member is used to lock one end of the connecting member 222 in the avoidance groove, the connecting plate 21, the supporting member 221 and the connecting member 222 can together enclose an installation space, and the cross bar 3 is inserted in the installation space.

[0052] The connecting plate 21, the supporting member 221 and the connecting member 222 can together form an installation space. When disassembling the cross bar 3, it is not necessary to completely remove the supporting assembly 22, thereby reducing the disassembly and assembly steps. Only the locking member is needed to lock the connecting member 222 in the avoidance groove, and the connecting member 222 and the supporting member 221 can be used to carry the cross bar 3. The locking member can be removed to separate the connecting member 222 from the supporting member 221, thereby removing the cross bar 3, thereby improving the installation and disassembly efficiency of the formwork early disassembly system.

[0053] In this embodiment, the locking member is a nut 223, the outer wall of the connecting member 222 is provided with an external thread, the nut 223 is sleeved on the periphery of the connecting member 222 provided with the external thread, and the nut 223 is used to adjust the height position of the cross bar 3 so that the cross bar 3 is always in contact with the supporting main template 12 to maintain stable support for the main template 12.

[0054] In some other embodiments, the locking member is a lock buckle, which is installed on one of the supporting member 221 and the connecting member 222. The other of the supporting member 221 and the connecting member 222 is provided with a locking groove. The connecting plate 21, the supporting member 221 and the connecting member 222 can be jointly enclosed by the installation space by locking the lock buckle in the locking groove.

[0055] When the cross bar 3 is used to support the formwork assembly 1, it is necessary to ensure that the cross bar 3 contacts the formwork assembly 1. However, when the diameter or thickness of the cross bar 3 is reduced and the installation space cannot be adjusted, the cross bar 3 can no longer contact the formwork assembly 1. To solve this problem, the present embodiment uses a nut 223 as a locking piece, and an external thread is provided on the outer wall of the connecting piece 222. By adjusting the position of the nut 223 on the connecting piece 222, the height position of the cross bar 3 is changed. Even if the cross bar 3 of different diameter or thickness is replaced, it can be ensured that the cross bar 3 always contacts and supports the formwork assembly 1.

[0056] The formwork early removal device of the present embodiment is applied to the construction field, and the installation form of the cross bar 3 is limited by the structural form of the building. When there are obstacles such as walls or beams at both ends of the formwork early removal device along the Y-axis direction, the cross bar 3 cannot be pulled out of the supporting assembly 22 along the Y-axis direction. In the present embodiment, the nut 223 is removed to separate the cross bar 3 from the supporting assembly 22 along the height direction.

[0057] Optionally, the column 4 is welded and fixed to the connecting plate 21, or the column 4 is threadedly connected to the connecting plate 21. The column 4 and the connecting plate 21 are fixedly arranged, and in the supporting state, the column 4 cannot slide relative to the connecting plate 21.

[0058] In this embodiment, the early formwork disassembly device includes a plurality of groups of formwork assemblies 1 arranged in sequence along the X-axis direction. The connecting supporting structure 2 located between two adjacent groups of formwork assemblies 1 includes two groups of supporting assemblies 22. When the connecting supporting structure 2 is fixedly connected to the two adjacent groups of formwork assemblies 1 at the same time, the two groups of supporting assemblies 22 of the same connecting supporting structure 2 are respectively located below the two adjacent groups of formwork assemblies 1, and each group of supporting assemblies 22 is installed with a cross bar 3.

[0059] In addition to being fixedly connected by the same connecting support structure 2, two adjacent groups of support assemblies 22 can also be supported by different cross bars 3 to ensure support strength.

[0060] The number of supporting components 22 installed on the same connecting plate 21 can be set according to actual needs. In the present embodiment, the supporting components 22 installed on the same connecting plate 21 are set to two groups. In some other embodiments, the supporting components 22 installed on the same connecting plate 21 are set to one group, or three groups, or four groups, or even more.

[0061] Optionally, the supporting member 221 is close to the column 4, and the connecting member 222 is far away from the column 4. When the supporting member 221 and the connecting member 222 need to be connected, the supporting member 221 is rotated toward the connecting member 222, and the supporting member 221 is far away from the column 4, which can prevent the column 4 from blocking or interfering with the rotation of the supporting member 221, and facilitate the operator to disassemble and assemble.

[0062] Optionally, one end of the supporting member 221 is connected to the connecting plate 21 by rotation around the Y-axis direction, and one end of the connecting member 222 is hinged to the connecting plate 21 through a universal hinge. The connecting member 222 is connected to the connecting plate 21 through the universal hinge, so that the connecting member 222 has a multi-directional rotation function to ensure that the connecting member 222 can quickly and accurately slide into the avoidance groove of the supporting member 221.

[0063] In this embodiment, two connecting supporting structures 2 arranged at intervals along the Y-axis direction are installed between two adjacent formwork assemblies 1, the bottom of each connecting supporting structure 2 is supported by a column 4, and two cross bars 3 are installed between the two corresponding connecting supporting structures 2 in the Y-axis direction. The two cross bars 3 respectively support the two adjacent formwork assemblies 1, and the two connecting supporting structures 2 fix the two adjacent formwork assemblies 1 to improve the safety and stability coefficient of the formwork support system.

[0064] In some other embodiments, three, four or even more cross bars 3 are detachably installed between at least two corresponding connecting supporting structures 2 in the Y-axis direction.

[0065] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
