Description

Technical Field

[0001] The utility model relates to the technical field of industrial construction engineering, in particular to a crane beam flange support connection structure. Background Art

[0002] The support point of traditional flanged supports is prone to misalignment, causing eccentric loads on the supporting column or shoulder beam, exacerbating weld cracking near the support point and reducing structural safety. The tension bolts connecting the crane beam are prone to breakage due to their limited deformation capacity. Therefore, improvements are needed to improve the crane beam flange support connection structure to enhance the load-bearing performance of the plant structure.

[0003] Therefore, in order to solve the above problems, a connection method is needed that can improve the crane beam flange support connection structure to enhance the stress-bearing performance of the plant structure. Utility Model Content

An end plate is provided on the crane beam, the end plate is connected to the support plate, and the lower flange of the crane beam extends out from the bottom of the end plate.

[0020] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention.

[0021] The following is combined with Figure 1-2 The utility model is described in further detail.

[0022] The embodiment of the utility model discloses a crane beam flange support connection structure.

[0023] Example 1

[0024] Reference Figure 1A crane beam flange support connection structure includes a support plate 1 and a relaxation part arranged above a column or shoulder beam. A crane beam with end plates 2 on both sides is placed on the support plate 1. An end plate 2 is provided on the crane beam, and the end plate 2 is connected to the support plate 1. The lower flange of the crane beam extends out from the bottom of the end plate 2. Two limit plates 6 are provided on the support plate 1. The two limit plates 6 are used to limit the displacement of the end plate 2. A filling plate 4 is provided on the end plate 2. Connection holes are opened on the end plate 2 and the filling plate 4. The anti-loosening part connects the end plate 2 and the filling plate 4 through the connection hole. The support plate 1 adds a limit plate 6 to prevent the end plate 2 from moving under the action of the reciprocating crane, causing the crane load to produce an eccentric load on the column or support.

[0025] The crane beam's web is equipped with a stiffening plate 3 parallel to the end plate 2. A filler plate 4 is mounted on the end plate 2. Connection holes are provided in the end plate 2, filler plate 4, and stiffening plate 3. The anti-loosening member connects the end plate 2, filler plate 4, and stiffening plate 3 through these holes. By anchoring one end to the stiffening plate 3, the anti-loosening screw is longer, thereby increasing its axial deformation capacity. This avoids the problem of brittle fracture of bolts caused by the short rods and insufficient deformation capacity of traditional connecting bolts, as well as the limited rotational capacity of the beam end.

[0026] A support plate 1 is positioned above the column. Two crane beams with end plates 2 are placed on the support plate 1. The lower ends of the end plates 2 extend beyond the lower flange of the crane beams, and their movement is restricted by stop plates 6 on the support plate 1. A filler plate 4 is placed between the end plates 2. Only one crane beam has a stiffening plate installed on its web, parallel to the end plates. Two stop plates 6 are welded above the support plate 1 to limit the movement of the two end plates 2.

[0027] The webs of the two crane beams are equipped with stiffening plates 3 parallel to the end plates 2. The thickness of the stiffening plates 3 is no less than that of the end plates 2 and no less than 16 mm. Bolt holes are provided in the two end plates 2, filler plates 4, and stiffening plates 3. The bolt holes are circular holes with a diameter 1.5-3 mm larger than the bolt diameter, and the center bolt holes are elongated holes. Anti-loosening bolts 5 connect the two end plates 2, filler plates 4, and stiffening plates 3 through the bolt holes. The anti-loosening bolts 5 are 10.9-grade high-strength bolts with a preload applied. The length of the anti-loosening bolts 5 is no less than 5 times the rod diameter. The anti-loosening bolts 5 are located within approximately 1 / 3 of the beam height near the bottom of the two crane beams.

[0028] The release element is located at approximately one-third of the crane beam's height, near the bottom. In this embodiment, the release element is a locking bolt 5, and the connection hole is a bolt hole. The locking bolt is a 10.9-grade high-strength bolt and is preloaded. The length of the locking bolt is no less than five times the rod diameter.

[0029] The bolt holes at both ends of the anti-loosening bolt 5 are round holes with a diameter 1.5-3 mm larger than the bolt diameter, and the middle bolt hole is a long hole.

[0030] The thickness of the stiffening plate 3 is greater than or equal to the thickness of the end plate 2. Specifically, the webs of the two crane beams are provided with stiffening plates 3 parallel to the end plates 2, wherein the thickness of the stiffening plates 3 is not less than the thickness of the end plates 2 and is not less than 16 mm.

[0031] By increasing the length of the anti-loosening screw and enhancing its axial deformation capacity, the present invention avoids the problem of brittle bolt fracture caused by the short deformation capacity of conventional connecting bolts, which results in limited rotational capacity at the beam end. Furthermore, the addition of a stop plate 6 to the support plate 1 prevents the end plate from moving under the action of a reciprocating crane, which could cause an eccentric effect of the crane load on the column or support.

[0032] Example 2

[0033] Reference Figure 2 The difference from Example 1 is that stiffening plates parallel to the end plates 2 are provided on the webs of the two crane beams, and the crane beam flange support connection structure is improved to enhance the stress-bearing performance of the plant structure.

[0034] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core ideas of the present invention. The above is only a preferred implementation method of the present invention. It should be pointed out that due to the limitations of textual expression, there are objectively infinite specific structures. For ordinary technicians in this technical field, without departing from the principles of the present invention, they can make several improvements, modifications or changes, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the concept and technical solution of the utility model to other occasions without improvement, should be regarded as the scope of protection of the present utility model.
