Description

Technical Field

[0001] This utility model belongs to the field of building formwork technology, specifically a building formwork connecting frame for civil engineering. Background Technology

[0002] A civil engineering formwork connection frame is a structural system used to connect and fix building formwork. It plays a key supporting and stabilizing role. The main function of the connection frame is to firmly connect the building formwork together during the construction process, ensuring the integrity and stability of the structure. The support frame is the main supporting part of the connection frame, usually made of steel, which has high strength and stability.

[0003] For example, a utility model patent with Chinese announcement number CN220645216U discloses a building formwork connecting frame for civil engineering, comprising: a formwork body, the surface of which is provided with several sets of evenly distributed connecting frames; each set of connecting frames includes two connecting plates, the two connecting plates being symmetrically distributed, and the inner wall of each connecting plate being slidably connected to two symmetrically distributed sliders, one end of which is fixedly connected to a top plate; by setting a limiting structure, under the action of the limiting structure, during the installation of the connecting frame, the position of the nut can be limited by the cooperation of the limiting block and the limiting groove, preventing the nut from turning back and loosening due to vibration during the compaction process, thus reducing the reinforcement effect, effectively strengthening the reinforcement effect of the formwork body, thereby improving the construction quality, and the installation and disassembly method is simple, effectively improving the construction efficiency.

[0004] However, in actual use, it was found that the device uses limiting and auxiliary structures to prevent the turntable and nuts from loosening during the vibration process after the concrete is poured, thus affecting the limiting effect.

[0005] However, due to the different sizes of different building formwork, the positioning of the turntable may not always remain at the predetermined position in actual application. In this case, if the auxiliary structure deviates from the predetermined position, it is impossible to effectively limit and fix the turntable accurately. In addition, multiple turntables are set on a set of connecting frames of the device. When fixing the building formwork, each turntable needs to be adjusted and fixed in turn, which is a cumbersome and time-consuming process. Therefore, it is necessary to provide a building formwork connecting frame for civil engineering. Utility Model Content

[0006] The purpose of this utility model is to provide a building formwork connection frame for civil engineering in order to solve the problems mentioned above.

[0007] The technical solution adopted by this utility model is as follows: A building formwork connecting frame for civil engineering includes a building formwork body. An installation bracket is provided on the outer surface of the building formwork body. Two fixed connecting frames are provided inside the installation bracket. An L-shaped installation groove is opened on the side of the two fixed connecting frames that are close to each other. A rack is fixedly installed inside the L-shaped installation groove. An adjustment mechanism connected to the rack is provided inside the building formwork body. A connecting fixing plate is provided at the end of the fixed connecting frame away from the installation bracket. A rectangular hole corresponding to the fixed connecting frame is opened on the front side of the connecting fixing plate. One end of the fixed connecting frame is inserted into the rectangular hole. A conical hole is opened on the top surface of one end of the fixed connecting frame. A conical limiting block is inserted into the conical hole.

[0008] In a preferred embodiment, the adjusting mechanism includes a bearing, a rotating shaft, and a pinion. The bearing is fixedly mounted on the front side of the mounting bracket, the rotating shaft is fixedly mounted through the middle of the bearing, and a pinion is fixedly mounted on one end of the rotating shaft. The pinion meshes with a rack.

[0009] In a preferred embodiment, a connecting plate is fixedly installed on one side of the mounting bracket and the fixed connecting frame, and a circular through hole is provided on one side of the connecting plate.

[0010] In a preferred embodiment, a rotating handwheel is fixedly mounted on the outer surface of the end of the rotating shaft away from the pinion.

[0011] In a preferred embodiment, the top surface of the fixed connecting frame away from the mounting bracket has a plurality of tapered holes arranged in an evenly spaced array.

[0012] In a preferred embodiment, a locking bolt is threadedly connected to one side of the rotating handwheel, and one end of the locking bolt abuts against one side of the building formwork body.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this utility model, due to the adoption of the above-mentioned solution, the construction personnel first pass one end of the fixed connecting frame through the rectangular hole, so that the connecting fixing plate is aligned and attached to the side of the building formwork body. At this time, the construction personnel insert the conical limiting block into the corresponding conical hole to limit and fix the connecting fixing plate, thereby achieving the connection and reinforcement of the building formwork body, thus forming a sturdy rectangular fixed reinforcement frame. The device can adjust the distance between the two fixed connecting frames through the set adjustment mechanism, so that they can move in a direction away from each other, thereby adapting to building formwork bodies of different sizes. The conical limiting block fixes the connecting fixing plate, so that it forms an integral whole with the installation bracket and the fixed connecting frame to reinforce the building formwork body. This ensures that the formwork will not loosen when pouring concrete, thereby effectively reinforcing the building formwork. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] refer to Figure 1 , Figure 2 This utility model provides a building formwork connecting frame for civil engineering, including a building formwork body 1, an installation bracket 2 on the outer surface of the building formwork body 1, and two fixed connecting brackets 3 inside the installation bracket 2; the installation bracket 2 facilitates the installation of the two fixed connecting brackets 3, thus facilitating the subsequent fixation of the building formwork body 1 and improving the stability of the building formwork body 1.

[0021] refer to Figure 1 , Figure 2 and Figure 3 The two fixed connecting frames 3 are provided with L-shaped mounting grooves 4 on their sides that are close to each other. A rack 5 is fixedly installed inside the L-shaped mounting groove 4. An adjustment mechanism 6 connected to the rack 5 is provided inside the building template body 1. The L-shaped mounting groove 4 facilitates the installation of the rack 5, and the adjustment mechanism 6 facilitates the adjustment of the fixed connecting frame 3, thus improving adaptability.

[0022] refer to Figure 1 , Figure 2 and Figure 3 The adjustment mechanism 6 includes a bearing 11, a rotating shaft 12, and a pinion 13. The bearing 11 is fixedly installed on the front side of the mounting bracket 2. The rotating shaft 12 is fixedly installed through the middle of the bearing 11. The pinion 13 is fixedly installed at one end of the rotating shaft 12. A rotating handwheel 16 is fixedly installed on the outer surface of the end of the rotating shaft 12 away from the pinion 13. The pinion 13 is meshed with the rack 5. Since the pinion 13 is meshed with the rack 5, when a person rotates the rotating shaft 12 by rotating the handwheel 16, the two fixed connecting frames 3 will move away from each other. This makes it easy to adjust the fixed connecting frames 3, so that the fixed connecting frames 3 can adapt to building template bodies 1 of different sizes and improve practicality.

[0023] refer to Figure 1 , Figure 2 The fixed connecting bracket 3 is provided with a connecting fixing plate 7 at the end away from the mounting bracket 2. The front side of the connecting fixing plate 7 is provided with a rectangular hole 8 corresponding to the fixed connecting bracket 3. One end of the fixed connecting bracket 3 is inserted into the inside of the rectangular hole 8. The rectangular hole 8 facilitates the fixed connecting bracket 3 to pass through it, so that one side of the connecting fixing plate 7 can fit against one side of the building template body 1, which facilitates subsequent fixing.

[0024] refer to Figure 1 , Figure 2 A tapered hole 9 is provided on the top surface of one end of the fixed connecting frame 3. Multiple tapered holes 9 are provided at equal intervals on the top surface of the end of the fixed connecting frame 3 away from the mounting bracket 2. A tapered limiting block 10 is inserted into the inside of the tapered hole 9. The multiple tapered holes 9 make it easy for personnel to insert and tap the tapered limiting block 10 into the corresponding tapered hole 9, thus facilitating the limiting and fixing of the connecting fixing plate 7.

[0025] refer to Figure 1 , Figure 2A connecting plate 14 is fixedly installed on one side of the mounting bracket 2 and the fixed connecting frame 3 respectively. A circular through hole 15 is opened on one side of the connecting plate 14. The connecting plate 14 and the circular through hole 15 facilitate the subsequent connection of the reinforcing support rod with bolts, so that the reinforcing support rod can support the mounting bracket 2 and the fixed connecting frame 3, thereby improving the stability of the building formwork body 1.

[0026] refer to Figure 1 , Figure 2 and Figure 3 One side of the rotating handwheel 16 is threaded with a locking bolt, and one end of the locking bolt abuts against one side of the building formwork body 1. With the locking bolt, the rotating handwheel 16 can be securely tightened when rotated to the appropriate position. This operation provides a significant limiting and fixing effect. Specifically, tightening the locking bolt enhances the fixing effect of the rotating handwheel 16, ensuring its positional stability. After the mounting bracket 2, the fixed connecting bracket 3, and the fixed connecting plate 7 with limiting and fixing are combined into a whole, a sturdy rectangular frame is formed. This rectangular frame has excellent stability. When vibration is performed inside the building formwork body 1, the entire rectangular frame can maintain its structural integrity and stability under the action of mutual tensile forces, without loosening or displacement. This design ensures safety and reliability during construction.

[0027] The implementation principle of the construction formwork connecting frame embodiment provided by this utility model is as follows: First, the construction worker places the U-shaped limiting connecting frame (composed of an installation bracket 2 and a fixing connecting frame 3) on the outside of the construction formwork body 1, ensuring it fits against the side of the formwork. Next, the construction worker passes one end of the fixing connecting frame 3 through the rectangular hole 8, aligning and fitting the connecting fixing plate 7 with the side of the construction formwork body 1. At this point, the construction worker inserts the conical limiting block 10 into the corresponding conical hole 9, thus limiting and fixing the connecting fixing plate 7, achieving reinforcement of the construction formwork body 1, thereby forming a robust connection. The rectangular fixed reinforcement frame, through the adjustment mechanism 6, allows the distance between two fixed connecting frames 3 to be adjusted, enabling them to move away from each other, thus accommodating building formwork bodies 1 of different sizes. The conical limiting block 10 fixes the connecting plate 7, forming an integral whole with the mounting bracket 2 and the fixed connecting frame 3 to reinforce the building formwork body 1. This ensures that the formwork will not loosen during concrete pouring. The device has a simple structure and is easy to operate. The adjustment mechanism 6 improves the adaptability to different formworks, while the conical limiting block 10 ensures the stable fixation of the connecting plate 7, thereby effectively reinforcing the building formwork.
