Description

Technical Field

[0001] This utility model relates to the technical field of formwork fixing devices for building engineering, and in particular to a formwork fixing device for building engineering. Background Technology

[0002] Formwork is a temporary support structure, manufactured according to design requirements, to shape concrete structures and components in the specified positions and geometric dimensions, maintain their correct position, and bear the self-weight of the formwork and external loads acting on it. The purpose of formwork engineering is to ensure the quality and safety of concrete engineering, accelerate the construction progress, and reduce project costs. The formwork structure used in cast-in-place concrete structure construction mainly consists of three parts: panels, supporting structures, and connectors. The panels are the load-bearing plates that directly contact the freshly poured concrete. The supporting structures are temporary structures that support the panels, concrete, and construction loads, ensuring that the formwork structure is firmly assembled and does not deform or break. Connectors are accessories that connect the panels and supporting structures into a whole. Formwork is the mold and support for the concrete pouring process. According to the properties of the materials, it can be divided into construction formwork, construction plywood, film-faced plywood, multi-layer plywood, double-sided adhesive-coated formwork, double-sided film-faced formwork, etc.

[0003] However, it still has some drawbacks. For example, the installation of construction formwork requires a lot of manpower, material resources, and time. When erecting the formwork, diagonal supports need to be erected on the outside of two opposing formworks, and concrete is poured between the two opposing formworks. This method of fixing the formwork by erecting diagonal supports is relatively complicated, which is not conducive to later dismantling and greatly increases the cost of using construction formwork.

[0020] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 The present invention will be described in further detail below.

[0021] Reference Figures 1-5 This utility model discloses a formwork fixing device for construction engineering, including a left outer frame 1 and a right outer frame 2, which are arranged opposite to each other. Each of the left and right outer frames has a mounting groove 11. A sliding fixing plate 12 is slidably connected to each mounting groove 11 of the left and right outer frames, and the two sliding fixing plates 12 can slide towards or away from each other. A first driving assembly 3 is installed on each of the left and right outer frames 1 and 2 to drive the sliding fixing plates 12 in their respective mounting grooves 11. A rubber pad 16 is fixed to the side of each sliding fixing plate 12 that is close to each other.

[0022] Both the left outer frame 1 and the right outer frame 2 have positioning grooves 13, into which feet 14 are inserted. A foot fixing bolt 141 is provided on the side wall of the left outer frame 1, passing through the side wall and threadedly connected to the foot 14. The connection between the right outer frame 2 and the foot 14 is the same as that between the left outer frame 1 and the foot 14. A fixing foot 15 is provided at the end of the foot 14 furthest from the positioning groove 13, passing through the foot 14 and inserting into the ground, thereby fixing either the left outer frame 1 or the right outer frame 2.

[0023] Two first driving components 3 are provided on both the left outer frame 1 and the right outer frame 2. The following description uses the first driving component 3 on the left outer frame 1 as an example. The first driving component 3 includes a first push screw 31 and a support plate 32. The support plate 32 is fixed to the left outer frame 1. The first push screw 31 passes through the support plate 32 and is threadedly connected to it. A first rotating block 33 is fixed to the end of the first push screw 31 near the template. The first rotating block 33 is located inside the sliding fixed plate 12 and is rotatably connected to it. Rotating the first push screw 31 causes the first rotating block 33 to move the sliding fixed plate 12. When the sliding fixed plate 12 moves, the two first push screws 31 on the sliding fixed plate 12 need to rotate together.

[0024] A positioning plate 4 is provided on each sliding fixing plate 12. Two positioning plates 4 are provided on each sliding fixing plate 12. A receiving groove 41 is opened on the top of the sliding fixing plate 12. The positioning plate 4 is inserted into the receiving groove 41 and can move up and down along the receiving groove 41. A clamping plate 42 is provided on the side of the positioning plate 4 near the template. A second driving assembly 5 for driving the clamping plate 42 to clamp the template is provided on the positioning plate 4.

[0025] The second drive assembly 5 includes a second push screw 51 and a second rotating block 52. The first push screw 51 passes through the positioning plate 4 and is threadedly connected to the positioning plate 4. The second rotating block 52 is fixed to one end of the second push screw 51. The second push screw 51 is located inside the positioning plate 4 and is rotatably connected to the positioning plate 4. When the second push screw 51 is rotated, it can drive the clamping plate 42 to move.

[0026] To increase the stability of the positioning plate 4, a telescopic rod 6 is provided between the positioning plate 4 and the foot 14. The telescopic rod 6 includes a first connecting rod 61 and a second connecting rod 62, with the first connecting rod 61 located below and the second connecting rod 62 located above. The first connecting rod 61 has a telescopic hole 63, and one end of the second connecting rod 62 is inserted into the telescopic hole 63. The foot 14 has a connecting groove 64, with the bottom of the first connecting rod 61 hinged to the groove wall of the connecting groove 64, and the top of the second connecting rod 62 hinged to the positioning plate 4. The second connecting rod 62 has multiple second locking holes 65, and the end of the first connecting rod 61 near the second connecting rod 62 has a first locking hole 66. A locking bolt 67 is provided on the first connecting rod 61, passing through the first locking hole 66 and one of the second locking holes 65 and threadedly connected to a nut.

[0027] A connecting bolt 7 is installed between two opposing templates. Connecting blocks 71 are fixed to both the left outer frame 1 and the right outer frame 2. The connecting bolt 7 passes through the connecting block 71 and is threadedly connected to a fixing nut 72. A connecting sleeve 73 is fitted onto the connecting bolt 7, located between the two templates. The connecting bolt 7 and the fixing nut 72 increase the stability of the connection between the left outer frame 1 and the right outer frame 2, thus providing better support for the templates.

[0028] The implementation principle of this utility model for fixing a formwork in construction engineering is as follows: When fixing the formwork, adjust the distance between the two formworks. After adjustment, install tie bolts to determine the distance between the two formworks. Fix the left outer frame 1 and the right outer frame 2 to the ground outside the formwork using fixing feet 15. Fix the left outer frame 1, the formwork, and the right outer frame 2 using connecting bolts 7 and fixing nuts 72. Then adjust the sliding fixing plates 12 on the left outer frame 1 and the right outer frame 2 to make the sliding fixing plates 12 press against the formwork. Then adjust the height of the positioning plate 4. After adjustment, fix the first connecting rod 61 and the second connecting rod 62 using locking bolts 67. Rotate the second push screw 51 to make the clamping plate 42 press against the formwork.

[0029] This invention uses two sliding fixing plates 12 to clamp and fix two templates together. The position of the sliding fixing plates 12 is adjustable, allowing the distance between the sliding fixing plates 12 and the templates to gradually decrease, thereby achieving the purpose of clamping the templates. Furthermore, a clamping plate 42 is provided above the sliding fixing plates 12, which clamps and supports the higher parts of the templates, thus improving the stability of the templates. This invention has a simple structure and is easy to disassemble.

[0030] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
