Description

Technical Field

[0001] The utility model relates to the technical field of curtain wall keel installation, in particular to a keel temporary fixing tool which is easy to install and can be reused. Background Art

[0002] The building curtain wall is a lightweight outer enclosure structure with decorative effects commonly used in modern buildings, consisting of curtain wall panels and keel systems. The curtain wall keel installation process has certain particularities, and its verticality and flatness deviations have a direct impact on the overall appearance and quality of the curtain wall; and the subsequent correction of curtain wall keel deviations is difficult to repair and requires a large amount of demolition work, which seriously affects the construction progress and cost control.

[0003] During the on-site keel installation process, the keel is transported by a lifting machinery. After being lifted into place, shaking is inevitable during the installation process, which leads to displacement deviation in the keel installation. In addition, on-site installation often uses bolt connection or welding connection to temporarily fix the keel. The commonly used temporary fixing method has a one-time success rate. If displacement deviation occurs during the installation process, the on-site correction measures are complicated and the subsequent repair is difficult, which cannot effectively improve the one-time pass rate of the keel installation construction. Summary of the invention

[0004] The utility model aims to provide a keel temporary fixing tool which is easy to install and reusable, has a flexible structure and can be suitable for different working environments.

[0005] To achieve the above-mentioned purpose, the utility model provides an easy-to-install, reusable temporary keel fixing tool, comprising a keel clamp, a retractable support rod and a steel structure clamp, the keel clamp is composed of two keel clamps with pull rings, and the two clamps are fixedly connected by bolts, the retractable support rod is composed of a screw rod and a telescopic adjustment device, the steel structure clamp is equipped with a fastening screw and a pull ring, and the keel clamp is connected to the steel structure clamp through the retractable support rod.

[0006] Preferably, the keel clamp is composed of two keel clamps with pull rings, and the two clamps are fixedly connected by bolts.

[0007] Preferably, the telescopic support rod is composed of a screw rod and a telescopic adjustment device, the telescopic adjustment device is a component with internal threads at both ends and a hollow middle part, one end of the screw rod is provided with a pull ring, and the other end is provided with an external thread that cooperates with the internal thread of the telescopic adjustment device.

[0008] Preferably, the steel structure clamp is a U-shaped member with a pull ring on the top and a fastening screw on one side. One end of the fastening screw is a circular pull ring for easy tightening, and the other end abuts against the steel structure liner.

[0009] Preferably, the keel clamp and the steel structure clamp are connected to the retractable support rod pull ring via pull rings on their respective sides, and a stable connection between the keel and the steel structure is formed by adjusting the retractable adjustment device.

[0010] The beneficial effects of the utility model are as follows: compared with the existing temporary fixing measures, the present application forms an effective and stable connection between the two through the steel structure clamp and the keel clamp, and the verticality and flatness of the keel can be fine-tuned by adjusting the support rod, thereby effectively improving the one-time pass rate of the keel installation construction; at the same time, the tool structure of the present application is flexible and reusable, and can be applied to different working environments.

[0011] The technical solution of the utility model is further described in detail below through the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solution of the utility model is further described below through the accompanying drawings and embodiments. Unless otherwise defined, the technical terms or scientific terms used in the utility model should be the common meanings understood by people with ordinary skills in the field to which the utility model belongs. "Including" or "comprising" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connected" or "connected" and similar words are not limited to physical or mechanical connections, but can include welding connections, etc., whether direct or indirect.

[0019] like Figure 1As shown, an easy-to-install, reusable keel temporary fixing tool includes a keel clamp 8, a telescopic support rod 4 and a steel structure clamp 3; the steel structure clamp 3 and the keel clamp 8 are connected by the pull rings at both ends of the telescopic support rod 4, and the installation position of the keel 7 is determined by adjusting the degree of tightening of the screws 5 at both ends of the telescopic adjustment device 6, so as to form a stable connection between the keel 7 and the steel structure 1. In addition, the pull rings at both ends of the telescopic support rod 4 can be designed as active connections to facilitate the replacement of keel clamps 8 of different sizes, which is better suitable for different working environments.

[0020] The keel clamp 8 is composed of two keel clamps 9 and is fastened to the keel 7 by bolts. It has a simple structure and is easy to operate.

[0021] The steel structure clamp 3 is a U-shaped component with a pull ring on the top, which is connected to the telescopic support rod 4 to achieve multi-angle connection with the keel 7; a fastening bolt 2 is provided on one side, and one end of the fastening bolt 2 is a circular pull ring. During on-site operation, it can be tightened manually or by inserting a steel bar and rotating it, which is easy to operate. A steel plate is welded on the other end to increase the contact area with the steel structure lining, forming a stable connection with the steel structure 1.

[0022] The telescopic support rod 4 is composed of a screw rod 5 and a telescopic adjustment device 6. One end of the screw rod 5 is provided with a pull ring, which is connected to the steel structure clamp 3 or the keel clamp 8, and the other end is provided with an external thread that cooperates with the internal thread of the telescopic adjustment device 6. When in use, a steel bar can be inserted into the hollow part in the middle of the telescopic adjustment device 6 to adjust the length of the screw rods 5 on both sides, and the installation position of the keel can be preliminarily determined. After the position is installed correctly, continue to fine-tune the adjustment device 6 to ensure that the verticality and flatness of the keel 7 meet the requirements of the design specifications and then permanently fix it. After fixation, the screw rod 5, the steel structure clamp 3 and the keel clamp 8 can be adjusted and loosened, and then removed and reused.
