Description

Technical Field

[0001] The utility model belongs to the technical field of support beam production, in particular to a corrosion-resistant steel structure beam. Background Art

[0002] Steel structure beams are beams made of steel. Crane beams and working platform beams in factories, floor beams in multi-story buildings, purlins in roof structures, etc. can all be made of steel structure beams. Existing steel structure beams are generally assembled by welding steel. Since welding has high requirements on temperature and workers' skills, the steel structure beams made by welding have different welding quality during production. Therefore, the welded steel structure bridges have certain safety hazards when in use. Welded parts are more likely to rust, which also affects the service life of the steel structure beams. Moreover, welding the steel structure into one is inconvenient in production and transportation due to its large volume. Moreover, after welding, it is not possible to adjust the load-bearing capacity of the steel structure beam according to demand. That is, if a larger load-bearing capacity is required, another supporting beam needs to be welded out again, which is inconvenient in production and does not have the universality of unified mass production. Utility Model Content

[0003] In order to solve the technical problems of the inconvenience in production and transportation of existing steel structure beams and the inability to adjust the load capacity according to demand, the utility model provides a corrosion-resistant steel structure beam, including a horizontally arranged lower support beam, an upper support beam arranged parallel to the lower support beam is provided above the lower support beam, and both the lower support beam and the upper support beam play a supporting role. Horizontally arranged lower fixing plates are fixed on the front and rear sides of the lower support beam, and the lower fixing plates are arranged along the length direction of the lower support beam. Upper fixing plates are provided on the front and rear sides of the upper support beam, and the upper fixing plates are horizontally arranged along the length direction of the upper support beam. A number of evenly spaced and vertically arranged mounting through holes are provided on the upper and lower fixing plates. The upper and lower support beams are both detachably fixed with a number of evenly spaced support seats. The support seats are concave-shaped, and are fixed with ear plates corresponding to the upper and lower fixing plates. The ear plates are provided with fixing holes corresponding to the mounting holes. The support seats are detachably fixed to the ear plates by fixing bolts and fixing nuts. The distance between the support seats on the upper and lower support beams can be adjusted to increase the number of support rods between the upper and lower support beams, thereby increasing the overall load capacity of the steel structure beam. A number of inclined support rods are provided between the upper and lower support beams. The upper ends of the support rods are hinged to the support seats on the upper support beam, and the lower ends of the support rods are hinged to the support seats on the lower support beam. An isosceles triangle structure is formed between the support seats and the support rods, making the structure stable and increasing the stability of the upper and lower support beams. Compared with welded steel structure beams, the support rods and support seats are fixed by hinged means, which is less affected by thermal expansion and contraction, can increase the service life of the steel structure beam, and facilitate the repair and replacement of damaged parts. The bottom end of the upper support beam is provided with a horizontal positioning slot along its length. The lower support beam is also provided with a positioning slot, and a positioning block is provided within the support base that corresponds to the positioning slot. During use, the positioning block is snapped into the positioning slot. The arrangement of the positioning slot and positioning block facilitates the alignment of the fixing holes on the ear plate with the mounting holes on the upper and lower fixing plates during assembly of the steel structure beam, facilitating the passage and securing of the fixing bolts. Two vertical and spaced support plates are fixed to the support base. The distance between the two support plates is slightly greater than the thickness of the two support rods. Horizontal assembly holes are provided on the support plates, and the ends of the support rods are assembled to the support plates via pins.

[0004] Preferably, a baffle is fixed on the base between the two support plates, and the cross section of the baffle is arc-shaped.

[0005] Preferably, a supporting portion is provided at the end of the supporting rod, and the supporting portion is arranged in an arc shape matching the baffle.

[0006] The above solution has the following advantages:

[0007] The support seat is detachably fixed to the upper support beam and the lower support beam by fixing bolts and fixing nuts. By adjusting the distance between the support seats on the support beam and the lower support beam, the number of support rods between the upper support beam and the lower support beam is increased, thereby increasing the overall load capacity of the steel structure beam; the setting of the positioning groove and the positioning block facilitates the assembly of the steel structure beam so that the fixing through holes on the ear plate correspond to the installation through holes on the upper fixing plate and the lower fixing plate, which is convenient for the fixing bolts to pass through and fix; an isosceles triangle structure is formed between the support seat and the support rod, which makes the structure stable and increases the stability of the upper support beam and the lower support beam. Compared with welded steel structure beams, the support rod and the support seat are fixed by a hinged manner, which is less affected by thermal expansion and contraction, can increase the service life of the steel structure beam, and is convenient for repairing and replacing damaged parts.
