Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a high-altitude Bailey support structure. Background Art

[0002] Bailey brackets, also known as Bailey plates, are mainly used as prefabricated components in construction. They have a wide range of applications, such as roads, railways, municipal administration, construction, water conservancy and other fields, and can be used in a variety of work scenarios.

[0003] High-altitude Bailey brackets are Bailey plates used in high altitudes. Usually, Bailey brackets are mainly composed of an upper chord frame, a lower chord frame, and a diagonal brace plate. The diagonal brace plate is welded between the upper chord frame and the lower chord frame to achieve a supporting function for bridges, etc. When processing the Bailey bracket, the staff needs to hold the diagonal brace plate and place the two ends of the diagonal brace plate between the upper chord frame and the lower chord frame to perform welding processing on the Bailey bracket. This processing method lacks a preliminary positioning mechanism and cannot achieve preliminary positioning between the diagonal brace plate, the upper chord frame, and the lower chord frame, which is inconvenient for the staff's processing operations. It is not only time-consuming and labor-intensive, but also has the problem of inaccurate welding points, which delays the construction period and affects the processing and use of the Bailey bracket. There are certain defects and shortcomings, and therefore, it needs to be improved. Utility Model Content

Positioning platforms 303 are formed on both sides of the rectangular seat body 301, and a positioning platform 303 on one of the fixing seats 3 is formed. An inclined support plate 4 is arranged between the platform 303 and the positioning platform 303 of another fixed seat 3; the inclined support plate 4 includes a support plate body 401, and two positioning blocks 402 integrally formed at both ends of the support plate body 401, the positioning blocks 402 abut against the corresponding positioning platform 303, and a limiting protrusion 403 is integrally formed on one side of the positioning block 402, and a limiting groove 302 is opened on the positioning platform 303 of the rectangular seat body 301 and penetrates to one side, and the limiting protrusion 403 is adapted on the corresponding limiting groove 302.

[0025] It should be noted that the upper chord frame 1, the vertical plate 2 and the lower chord frame 5 constitute the main part of the Bailey bracket, and the vertical plate 2 is fixedly connected between the upper chord frame 1 and the lower chord frame 5 in sequence to achieve the initial support and fixing effect between the upper chord frame 1 and the lower chord frame 5. By setting a fixing seat 3 in the middle of the upper chord frame 1, the lower chord frame 5 and the vertical plate 2, the setting of the fixing seat 3 is used for the installation of the diagonal support plate 4, and the initial limiting and abutting support effect of the installation of the diagonal support plate 4 is performed. The main part of the fixing seat 3 is a rectangular seat body 301, and both sides of the rectangular seat body 301 are provided with limiting grooves 302 and positioning platforms 303. The main part of the diagonal support plate 4 is a support plate body 401, and both ends of the support plate body 401 are provided with positioning blocks 402. The positioning blocks 40 2 is provided with a limiting protrusion 403, and the limiting groove 302 penetrates to one side of the rectangular seat body 301. When assembling the diagonal support plate 4, the limiting protrusion 403 is slid along the limiting groove 302, and the positioning block 402 is abutted against the positioning platform 303. After assembly, an abutment effect between one side of the positioning block 402 and the vertical plate 2 and the string frame can be formed, and the diagonal support plate 4 supports the Bailey bracket. This method can realize the support between the upper string frame 1, the vertical plate 2 and the lower string frame 5 through the diagonal support plate 4, has good structural stability, and can realize the initial positioning of the diagonal support plate 4 during assembly, which is beneficial to the assembly operation of the diagonal support plate 4, can reduce the overall processing difficulty of the Bailey bracket, and can ensure the processing accuracy, which is suitable for actual use.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, one side of the positioning block 402 abuts against the corresponding vertical board 2 .

[0027] It should be noted that one side of the positioning block 402 can abut against the corresponding upper chord frame 1, vertical plate 2, and lower chord frame 5, so as to realize the supporting effect of the diagonal brace plate 4 on the overall Bailey support and strengthen the overall stability of the Bailey support.
