Abstract
The utility model discloses a splice joint structure of girder square steel on escalators or moving sidewalks, comprising two girder square steel, wherein the ends of the two girder square steel are fixed together by permanent butt weld with a base plate; the base plate adopts reinforcing square steel; the two ends of the reinforcing square steel respectively stretch into the cavities of the ends of the two girder square steel; the outer surfaces of the ends of the two girder square steel are provided with a plurality of through holes; the through holes are filled with melted flux; and the girder square steel and the reinforcing square steel are subjected to plug welding. The girder square steel is subjected to butt welding by the reinforcing square steel and the girder square steel and the reinforcing square steel are subjected to plug welding, thus forming a square steel. The length and the mechanical performance of the square steel can meet the requirement of metallic framework manufacturing, thus reducing unnecessary metallic framework segmentation and lowering the metallic framework manufacturing cost.
Description
Technical field
The utility model relates to girder square steel splicing construction on a kind of escalator or the moving sidewalk.
Background technology
At present, standard square steel length on the market often can not satisfy the making requirement of the metallic framework girder of escalator and moving sidewalk, will increase the segments of metallic framework like this, making the unreasonable structure of metallic framework has also increased the cost of manufacture of making metallic framework.
Summary of the invention
The purpose of this utility model provides on a kind of escalator or the moving sidewalk two girder square steel and is weldingly fixed on mutually and forms a length together and can satisfy the splicing construction that metallic framework is made the square steel that requires by strengthening square steel.
For achieving the above object, the technical solution adopted in the utility model is: girder square steel splicing construction on escalator or the moving sidewalk, comprise two girder square steel, the end of described two girder square steel fixes together by the butt welding of permanent band backing plate, described backing plate adopts strengthens square steel, the both ends of described reinforcement square steel are stretched into respectively in the inner chamber of described two girder square steel ends, offer a plurality of perforation on the outer surface of described two girder square steel ends, fill up the solder flux after the thawing in the described perforation, described girder square steel and described reinforcement square steel plug welding mutually connect.
Described perforation has many rows, and to arrange described perforation spaced along the Width of described girder square steel more, and every row has a plurality of described perforation, and a plurality of perforation are spaced along the length direction of described girder square steel described in every row.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage: two girder square steel are by strengthening the square steel weldering that connects, and girder square steel and the plug welding mutually of reinforcement square steel, thereby form a square steel, the length of this root square steel can satisfy the requirement that metallic framework is made, and this root square steel also satisfies the requirement that metallic framework is made on mechanical property, thereby reduced unnecessary metallic framework segmentation, reduced the cost of manufacture of metallic framework.
Description of drawings
Accompanying drawing 1 is vertical scheme drawing of the present utility model, and the end that has shown two girder square steel fixes by the butt welding of permanent band backing plate;
The specific embodiment
Further set forth structure of the present utility model below in conjunction with accompanying drawing.
Shown in Fig. 1-2, girder square steel splicing construction on escalator or the moving sidewalk, comprise two girder square steel 1, the end of two girder square steel 1 fixes together by the butt welding of permanent band backing plate, backing plate adopts strengthens square steel 2, strengthening the both ends of square steel 2 stretches into respectively in the inner chamber of two girder square steel 1 ends, when butt welding, the butt weld of two girder square steel 1 is filled by solder flux, weld was polished after welding was finished, strengthening square steel 2 also is weldingly fixed in two girder square steel 1 as permanent backing plate, offer a plurality of perforation 3 on the outer surface of two girder square steel 1 ends, the solder flux 4 after the thawing is filled up in perforation in 3, realize girder square steel 1 with strengthen square steel 2 mutually plug welding connect, carry out plug welding and make and strengthen square steel 2 and fix firmly mutually strengthening square steel 2 by the hole on the girder square steel 1 with two girder square steel 1.Two girder square steel 1 are by strengthening square steel 2 weldering that connects, and girder square steel 1 and the plug welding mutually of reinforcement square steel 2, thereby form a square steel, the length of this root square steel can satisfy the requirement that metallic framework is made, and this root square steel also satisfies the requirement that metallic framework is made on mechanical property, thereby reduced unnecessary metallic framework segmentation, reduced the cost of manufacture of metallic framework.
In Fig. 1, on the Width of girder square steel 1, many rows perforation 3 of setting is separately arranged, have among every row a plurality of along the spaced perforation 3 of the length direction of girder square steel 1, by bore a hole 3 realize girder square steel 1 and reinforcement square steel 2 mutually plug welding connect, as shown in Figure 2.
To sum up, two girder square steel 1 butt joints, the embedded reinforcement square steel 2 of interface, adopt the butt joint welding manner of permanent band backing plate between two girder square steel 1, and girder square steel 1 with strengthen plug welding mutually between the square steel 2, then with two girder square steel 1 with strengthen square steel 2 solder together firmly, then weld is polished, form a square steel, this root square steel meets required mechanical property under the technical requirements of escalator and moving sidewalk metallic framework, avoided because the limitation of standard square steel length, and the unnecessary segmentation of the metallic framework that causes has reduced the cost of manufacture of metallic framework.
