Description

Technical Field

[0001] The utility model relates to the technical field of support structures, and particularly relates to a flexible cross brace. Background Art

[0002] As a truss of a house roof structure, a steel roof truss can bear the weight of the roof and the framework. During the installation process of the steel roof truss, since each truss is in an unstable form, steel plates and steel pipes are often welded together to form a cross brace to stabilize the steel roof truss. The cross brace plays an important role in longitudinal stability and enhancing longitudinal rigidity. However, the existing cross braces have the disadvantages of heavy weight, inability to adjust the tightness, and inability to be reused. To solve the above problems, it is particularly necessary to design a new type of flexible cross brace. Summary of the Utility Model

[0003] Aiming at the deficiencies in the prior art, the purpose of the utility model is to provide a flexible cross brace, which has a simple structure, reasonable design, reduces weight, can adjust the fastening degree, can be reused repeatedly, has strong practicability, and is easy to popularize and use.

[0004] To achieve the above purpose, the utility model is realized through the following technical solutions: A flexible cross brace includes steel wires, UU-shaped turnbuckles, and snap rings. The steel wires are connected by UU-shaped turnbuckles, and snap rings are connected to the ends of the steel wires. The three form a connecting piece. Two connecting pieces form a group and cross each other to form an X-shaped cross brace structure, and are installed at the end of a horizontal or vertical steel roof truss through the snap rings.

[0005] Preferably, the ring body of the snap ring is fixedly connected to the lifting lug plates symmetrically fixed on the steel roof truss. The connection between the snap ring and the end of the steel roof truss is simple and fast.

[0006] The beneficial effects of the utility model: The device has a reasonable structure, can reduce weight, can adjust the fastening degree, can be reused repeatedly, is safe and reliable, and has a broad application prospect. Brief Description of the Drawings

[0007] The following will describe the utility model in detail with reference to the drawings and specific embodiments;

[0010] To make the technical means, creative features, achieved purposes, and functions of the utility model easy to understand, the following will further elaborate on the utility model in combination with specific embodiments.

[0011] Referring to Figure 1-2 , the following technical solution is adopted in this specific embodiment: a flexible scissors brace, which includes a steel wire rope 1, a UU-shaped flower basket bolt 2 and a snap ring 3. The steel wire ropes 1 are connected by the UU-shaped flower basket bolt 2, and the end of the steel wire rope 1 is connected with a snap ring 3. The three form a connecting piece. Two connecting pieces are in a group and cross each other to form an X-shaped scissors brace structure, and are installed at the end of the horizontal or vertical steel roof truss 4 through the snap ring 3.

[0012] This specific embodiment uses the connection of the steel wire rope and the UU-shaped flower basket bolt, which is simple and light, suitable for any span size. At the same time, the ring body of the snap ring 3 is connected and fixed with the lug plate 5 symmetrically fixed on the steel roof truss 4. The snap ring 3 is used to connect with the end of the steel roof truss 4. Whether it is installation connection or high-altitude demolition, it can be operated simply and quickly, improving work efficiency.

[0013] This specific embodiment forms a stable structure through the steel wire rope, the UU-shaped flower basket bolt and the snap ring. Compared with the traditional way of welding steel plates and steel pipes to form a scissors brace, it can not only greatly reduce the weight, but also the device can adjust the tightening degree by using the UU-shaped flower basket bolt, which is more flexible, practical, safe and reliable. At the same time, the scissors brace can be reused and is not limited by the span size. This scissors brace structure can be used for horizontal and vertical connection of steel roof trusses and has a broad market application prospect.

[0014] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
