[0023] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0026] See also Figures 1 to 7 The utility model provides a formwork auxiliary fixing structure, which is used in a tied steel bar structure formed into a roof structure. The formwork auxiliary fixing structure includes a support member 10 and a connecting member 20. The support member 10 is die-cast by iron or iron alloy. A limiting protrusion 11 is extended outward from the circumference of the support member 10. The limiting protrusion 11 is used to be connected with the steel bar 40, so that the steel bar 40 supports the limiting protrusion 11. After the roof is poured, the limiting protrusion 11 is embedded in the concrete, which can bear the force effect of the entire formwork auxiliary fixing structure.

[0027] The upper end of the connecting member 20 is fixed to the supporting member 10, and the lower end of the connecting member 20 is connected to the limiting template 30. The limiting template 30 is arranged under the tied steel bar structure used to form the roof structure, so that when the roof is poured, it can effectively support the concrete poured in the tied steel bar structure, and at the same time strengthen the anchoring effect between the limiting template and the poured concrete, effectively prevent the hollowing phenomenon between the limiting template and the poured concrete, and avoid the limiting template from detaching from the poured concrete structure; in this embodiment, the limiting template 30 is designed to be a non-removal structure and becomes a part of the cast roof structure; that is, the limiting template 30 does not need to be removed from the roof after the concrete poured on the roof is cured, because the limiting protrusion of the supporting member 10 supporting the connecting member 20 11 is embedded in the concrete and the limiting protrusion 11 is supported by the steel bars 40 in the tied steel bar structure, which effectively improves the stability of the support member 10 in the roof concrete structure after maintenance is completed. The support member 10 is connected to the limiting template 30 with the connecting member 20. The limiting template 30 can become a part of the roof without being removed, which effectively reduces the maintenance difficulty after pouring the roof; in this embodiment, the limiting template is a fiberboard structure, and the limiting template 30 is designed to be a part of the roof. The limiting template 30 needs to have good stability when it is prefabricated. A plurality of reinforcing ribs 31 are arranged at intervals in the limiting template 30 to strengthen the rigidity of the limiting template 30 during the construction process, thereby forming an effective support effect for pouring concrete.

[0028] Furthermore, in order to improve the stability of the connection between the limiting protrusion 11 and the steel bar 40, the present invention also adopts the following structure to solve the problem.

[0029] In one embodiment, the limiting protrusions 11 are respectively arranged on opposite sides of the support member 10, and a through groove 111 is opened on the limiting protrusion 11. The through groove 111 is used for allowing the steel bar 40 to pass through. Before tying the steel bar 40, the steel bar 40 can be passed through the through groove 111 of the limiting protrusion 11, thereby completing the fixing effect of the support member 10.

[0030] Alternatively, in order to reduce the difficulty of connecting the limiting protrusion 11 and the steel bar 40, the cross-section of the through groove 111 of the limiting protrusion 11 can be designed to be a semi-cylindrical structure, so that there is no need to connect the steel bar 40 to the limiting protrusion 11 before tying the steel bar 40. That is, after tying the steel bar structure, it is only necessary to put the steel bar 40 into the through groove 111 of the limiting protrusion 11 to achieve a stable connection effect between the limiting protrusion 11 and the steel bar 40, so that the steel bar 40 supports the limiting protrusion 11, and then after the roof is poured, the limiting protrusion 11 is embedded in the concrete, which can bear the force effect of the entire formwork auxiliary fixing structure.

[0031] In one embodiment, a first threaded hole 12 is opened in the middle of the support member 10, and a first threaded portion 21 is provided at the upper end of the connecting member 20. The connecting member 20 is fixed in the first threaded hole 12 through the first threaded portion 21, thereby achieving a stable connection effect between the connecting member 20 and the support member 10.

[0032] Example 1

[0033] See also Figure 1 、 Figure 2 and Figure 7 In this embodiment, the connection effect between the connecting member 20 and the limiting template 30 can be solved by adopting the following structure.

[0034] Specifically, a second threaded portion 22 is provided at the lower end of the connecting member 20, and a second threaded hole 32 is opened on the limiting template 30. The second threaded portion 22 at the lower end of the connecting member 20 is fixed in the second threaded hole 32 of the limiting template 30, thereby achieving a stable connection effect between the connecting member 20 and the limiting template 30.

[0035] In this embodiment, the thread direction of the second threaded portion 22 is opposite to that of the first threaded portion 21; during specific assembly, the upper end of the connecting member 20 needs to be aligned with the first threaded hole 12 in the middle of the support member 10, and the lower end of the connecting member 20 needs to be aligned with the second threaded hole 32 on the limiting template 30. The connecting member 20 is rotated and an upward force is applied to the limiting template 30 at the same time. The upper end of the connecting member 20 will rotate into the first threaded hole 12, and the lower end of the connecting member 20 will rotate into the second threaded hole 32, thereby achieving a stable connection effect between the connecting member 20 and the support member 10 and the limiting template 30 respectively, and then the supporting effect of the support member 10 on the limiting template 30 is achieved through the connecting member 20. While the connecting member 20 is stably connected to the support member 10, the limiting template 30 will not detach from the roof after pouring, that is, the structure of the limiting template 30 as part of the roof ceiling will also be in a stable state.

[0036] Furthermore, before pouring concrete on the roof, in order to further improve the stability of the connection between the limiting template 30 and the connecting member 20, the present invention adopts the following solution.

[0037] In one embodiment, a nut 50 is sleeved on the connector 20, and the nut 50 is connected to the connector 20 by a threaded manner. The nut 50 is placed above the limiting template 30. When the lower end of the connector 20 is threadedly connected to the limiting template 30, the nut 50 is rotated to move along the direction of the connector 20, thereby making the nut 50 close to the upper end surface of the limiting template 30, thereby improving the stability of the connection between the lower end of the connector 20 and the limiting template 30. After the concrete poured on the roof is cured, the limiting template 30 does not need to be removed from the roof, which effectively reduces the difficulty of maintenance after pouring the roof.

[0038] Furthermore, in order to improve the stability of the fit between the nut 50 and the limiting template 30, a gasket 60 is also provided on the connecting piece 20, and the gasket 60 is located between the nut 50 and the limiting template 30, so as to increase the contact area between the nut 50 and the limiting template 30 through the gasket 60, thereby further improving the stability of the connection between the lower end of the connecting piece 20 and the limiting template 30. After the concrete poured on the roof is cured, the limiting template 30 does not need to be removed from the roof, which effectively reduces the difficulty of maintenance after pouring the roof.

[0039] In order to improve the supporting stability of the concrete of the limiting formwork 30 when pouring the roof, it is often necessary to set support members 10 and connecting members 20 at multiple positions of the limiting formwork 30, so that the fixation of the limiting formwork 30 is more stable; in this embodiment, connecting members 20 are set at the four corners of the limiting formwork 30, and the upper end of the connecting member 20 is fixed on the support member 10.

[0040] In order to further improve the supporting stability of the concrete of the limiting formwork 30 when pouring the roof, connecting pieces 20 are provided at the four corners and the center of the limiting formwork 30, and the upper ends of the connecting pieces 20 are fixed to the supporting pieces 10.

[0041] Example 2

[0042] See also Figure 3 、 Figure 4 、 Figure 5 and Figure 7 In this embodiment, the connection effect between the connecting member 20 and the limiting template 30 can be solved by adopting the following structure.

[0043] Specifically, a limiting cap 23 is provided at the lower end of the connecting member 20, and a limiting groove 33 is provided at the bottom end of the limiting template 30. The connecting member 20 passes through the limiting template 30, and the limiting cap 23 is placed in the limiting groove 33, so that the supporting effect of the limiting cap 23 on the limiting template 30 is utilized to realize the supporting effect of the connecting member 20 on the limiting template 30. While the connecting member 20 is stably connected to the supporting member 10, the limiting template 30 will not detach from the roof after casting, that is, the structure of the limiting template 30 as part of the roof ceiling will also be in a stable state.

[0044] Furthermore, before pouring concrete on the roof, in order to further improve the stability of the connection between the limiting template 30 and the connecting member 20, the present invention adopts the following solution.

[0045] In one embodiment, a nut 50 is sleeved on the connecting member 20, and the nut 50 is connected to the connecting member 20 by a threaded manner. The nut 50 is placed above the limiting template 30. When the connecting member 20 passes through the limiting template 30 and is fixedly connected to the support member 10, the nut 50 is rotated so that the nut 50 moves along the direction of the connecting member 20, thereby making the nut 50 close to the upper end face of the limiting template 30, and cooperates with the limiting cap 23 structure to clamp the limiting template 30, thereby further improving the stability of the connection between the limiting template 30 and the connecting member 20.

[0046] Furthermore, in order to improve the stability of the fit between the nut 50 and the limiting template 30, a gasket 60 is also provided on the connecting member 20, and the gasket 60 is located between the nut 50 and the limiting template 30 to increase the clamping force of the nut 50 and the limiting cap 23 on the limiting template 30 and improve the stability of the fit between the nut 50 and the limiting template 30.

[0047] In order to improve the supporting stability of the concrete of the limiting formwork 30 when pouring the roof, it is often necessary to set support members 10 and connecting members 20 at multiple positions of the limiting formwork 30, so that the fixation of the limiting formwork 30 is more stable; in this embodiment, connecting members 20 are set at the four corners of the limiting formwork 30, and the upper end of the connecting member 20 is fixed on the support member 10.

[0048] In order to further improve the supporting stability of the concrete of the limiting formwork 30 when pouring the roof, connecting pieces 20 are provided at the four corners and the center of the limiting formwork 30, and the upper ends of the connecting pieces 20 are fixed to the supporting pieces 10.

[0049] Taking the template auxiliary fixing structure corresponding to the second embodiment as an example, when the present invention is specifically applied, before pouring the concrete of the roof, a perforation 34 is opened at a specific position of the limiting template 30 according to the design specifications for the connection member 20 to pass through and set; at the same time, a plurality of support members 10 are matched and placed at a specific position of the tied steel bar structure according to the design specifications, and then the connection member 20 is passed through the perforation 34 of the limiting template 30 and fixed on the support member 10. At this time, the upper end of the connection member 20 is fixed to the support member 10 through the first threaded portion 21, and the limiting cap 23 set at the lower end of the connection member 20 is placed on the limiting position of the limiting template 30. The support 10 is embedded in the concrete, which effectively improves the stability of the support 10 in the roof concrete structure after the curing. The support 10 is connected to the limiting template 30 with the connecting piece 20. The limiting template 30 does not need to be removed and can become a part of the roof, which effectively reduces the difficulty of maintenance after the roof is poured.

[0050] To sum up, the utility model provides a template auxiliary fixing structure by setting a support member 10 and a connecting member 20, and a limiting protrusion 11 extending outward from the side of the support member 10. The limiting protrusion 11 is used to be connected with the steel bar 40, so that the steel bar 40 supports the limiting protrusion 11. After the roof is poured, the limiting protrusion 11 is embedded in the concrete, which effectively improves the stability of the support member 10 in the roof concrete structure after maintenance. The support member 10 is connected to the limiting template 30 with the connecting member 20. The limiting template 30 can become a part of the roof without being dismantled, which effectively reduces the difficulty of maintenance after pouring the roof.
