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

The preparation method of regular hexagon Honeycomb Beam

Technical field

The present invention relates to the preparation method of a kind of regular hexagon hole Honeycomb Beam, belong to building material field.

Background technology

In construction work, the deadweight size of structural element directly has influence on the size of building load, and load of buildings is big; The ability of the transmission load of Force transmission parts just requires greatly; Supporting capacity to ground also requires height, often need carry out strict processing to ground because building load is big, increases building costs; The primary structure member that building transmits load often also will strengthen reinforcement, also will raise the cost.Therefore, reducing the load of building member, improve the supporting capacity of building Force transmission parts, is the target that engineers and technicians explore pursuit always.

From important light, but also there are the problem that reduces to conduct oneself with dignity in steel work and reinforced concrete structure ratio.In steel structure member, in order to alleviate member dead weight, often the web position with section steel beam cuts into circular hole or regular hexagon hole, so neither influences the supporting capacity of member, has alleviated deadweight again, is a kind of behave that makes the best of both worlds.This beam is commonly called " Honeycomb Beam ".

Regular hexagon is a special body, and preparation method is complicated.And perforate on the member web can only alleviate member dead weight, can not increase the supporting capacity and the rigidity of member.

Summary of the invention

The present invention provides the preparation method of a kind of regular hexagon hole Honeycomb Beam, can either improve the supporting capacity of Honeycomb Beam, again rigidity is also doubled.Its principle is: if in a rectangle, carry out setting-out according to Fig. 1; And cut into the shape of Fig. 2 by drawn line; And make up according to certain rule, will obtain the shape of Fig. 3, and the length dimension of Fig. 3 is constant; Width dimensions has increased by 1 times than Fig. 1, and has formed the regular hexagon hole that we need.

The present invention realizes with following technical scheme: the preparation method of a kind of regular hexagon hole Honeycomb Beam comprises top flange, bottom flange and is positioned at a plurality of regular hexagon holes on the web.

The preparation method of above-mentioned regular hexagon hole Honeycomb Beam; Carry out as follows:

1) draw three parallel lines at the web place of I shape section steel beam, wherein two respectively at frange plate place up and down, and another is at the web midline position;

2) two lines at above bottom wing listrium place are orthohexagonally followingly, and the length of side is 2/1.73 times of distance between two lines, draws regular hexagon half;

3) method that adopts flame to cut cuts into two parts with web along the line.

4) the web assembling combination with two-part beam becomes regular hexagon hole Honeycomb Beam, and the web with two-part beam welds along match line then.

Beam is a flexural member, and deck-molding strengthens, and rigidity has just improved certainly.

The invention has the beneficial effects as follows; The Honeycomb Beam depth of section made from said method doubles than former section bar approximately, and supporting capacity, rigidity also double, have section form rationally, from heavy and light, bending rigidity is big, bearing capacity is high; Can practice thrift advantages such as steel, remarkable in economical benefits in a large number.

Description of drawings

Below in conjunction with accompanying drawing and embodiment method of the present invention is further specified.

Fig. 1 is that three parallel lines sketch mapes are drawn at the web place;

Fig. 2 is that section steel beam is drawn the line of cut sketch map;

Fig. 3 is a part sketch map after the cutting;

Fig. 4 is the b part sketch map after the cutting;

Fig. 5 is with the Honeycomb Beam sketch map after a, the welding of b two parts.

Among the figure: the 1-top flange; The 2-web; The 3-bottom flange; 4-Honeycomb Beam line of cut; 5-Honeycomb Beam hole; 6-Honeycomb Beam sealing wire.

The specific embodiment

Section bar generally adopts i iron, when the depth of section of beams designed is 360 millimeters, gets final product with No. 18 i iron, than practicing thrift a lot of expenses with No. 36 i iron.(180 millimeters of the web heights of No. 18 i iron).

Height as shown in Figure 4 is 360 millimeters a regular hexagon hole Honeycomb Beam, and it comprises top flange 1, bottom flange 3 and is positioned at a plurality of regular hexagon holes on the web 2.When the flange width up and down of the top flange of designing requirement width and bottom flange width and No. 18 i iron or No. 18 H shaped steel and thickness, when web thickness is identical; Just can make with No. 18 i iron or No. 18 H shaped steel, and need perforate on identical No. 36 i iron of flange width up and down and thickness, web thickness or No. 36 H shaped steel.

Its preparation method is carried out as follows:

1) as shown in Figure 1, draw three parallel lines at the web place of I shape section steel beam, wherein two respectively at frange plate place up and down, and another is at the web midline position;

2) as shown in Figure 2, two lines at above bottom wing listrium place are orthohexagonally followingly, and the length of side is 2/1.73 times of distance between two lines, draws regular hexagon half;

3) like Fig. 3, shown in Figure 4, adopt the method for flame cutting, web 2 is cut into a, b two parts along the line;

4) as shown in Figure 5, web 2 assembling combination of a, the two-part beam of b are become regular hexagon hole Honeycomb Beam, then a, b two parts are welded along match line; Eliminate the distortion that cutting causes, must proofread and correct member before the Honeycomb Beam assembling welding.Assembling is welded under the situation that does not have specific (special) requirements, adopts the manual electric arc welding welding.

The Honeycomb Beam result of use of perforate making is identical on the Honeycomb Beam of making like this and No. 36 i iron or No. 36 H shaped steel.

1, section bar generally adopts i iron, when the depth of section of beams designed is 360 millimeters, gets final product with No. 18 i iron, than practicing thrift a lot of expenses with No. 36 i iron.(No. 18 i iron be exactly 180 millimeters of web heights)

3, beam is a flexural member, and deck-molding strengthens, and rigidity has just improved certainly.
