Problems solved by technology

[0004] The regular hexagon is a special shape, and the production method is more complicated
Moreover, opening holes on the member web can only reduce the self-weight of the member, but cannot increase the bearing capacity and stiffness of the member

Embodiment Construction

[0021] I-beams are generally used for profiles. When the section height of the designed beam is 360mm, use No. 18 I-beams, which saves a lot of cost than using No. 36 I-beams. (The web height of 18 gauge I-beam is 180 mm).

[0022] Such as Figure 4 The shown honeycomb beam with regular hexagonal holes with a height of 360 mm includes an upper flange 1 , a lower flange 3 and a plurality of regular hexagonal holes on the web 2 . When the upper and lower flange widths required by the design are the same as the upper and lower flange widths, thicknesses and web thicknesses of No. 18 I-beams or No. 18 H-beams, you can use No. 18 I-beams or No. 18 H It is not necessary to drill holes on No. 36 I-beam or No. 36 H-beam with the same width, thickness and web thickness of the upper and lower flanges.

[0023] Its preparation method is carried out as follows:

[0024] 1) if figure 1 As shown, draw three parallel lines at the web of the I-shaped steel beam, two of which are at the up...

Abstract

The invention relates to a manufacture method of a regular hexagon castellated beam and belongs to the field of building materials. The method comprises the following steps that 1) three parallel lines are drawn on a web plate part of an I-shaped sectional steel beam, wherein the two parallel lines are respectively positioned at upper and lower flange plate parts, and the third parallel line is positioned in the mid line position of the web plate; 2) the two lines positioned at the upper and lower flange plate parts are upper and lower edges of regular hexagon, the edge length is 1 / 1.73 times of the distance between the two lines, and the half regular hexagon is drawn; 3) a flame cutting method is adopted, and the web plate is cut into two parts a and b; 4) the web plates of the beams of the two parts a and b are subjected to split combination to form the regular hexagon hole castellated beam, and then, the two parts a and b are welded along the split line. The method has the beneficial effects that the cross section height of the manufactured castellated beam is increased by about one time through being combined with that of the original sectional material, the carrying capability and the rigidity are also improved by one time, and the method has the advantages that the cross section form is reasonable, the dead weight is light, the bending resistance rigidity is high, the carrying capability is high, a great number of steel materials can be saved, the economic benefits are obvious, and the like.

Description

technical field [0001] The invention relates to a method for manufacturing a honeycomb beam with regular hexagonal holes, belonging to the field of building materials. Background technique [0002] In construction engineering, the self-weight of structural components directly affects the load of the building. When the load of the building is large, the load-transferring capacity of the force-transmitting components is required to be large, and the bearing capacity of the foundation is also required to be high. Often because the building The heavy load requires strict treatment of the foundation, which increases the construction cost, and the stress-bearing components of the building that transmit the load often need to be strengthened, which also increases the cost. Therefore, reducing the load of building components and improving the bearing capacity of building force-transmitting components are the goals that engineers and technicians have been exploring and pursuing.
