Abstract
The invention discloses a continuous hanging ladder for a steel structure welding process. The continuous hanging ladder comprises two parallel uprights (1) and a hanging ladder body, wherein the hanging ladder body is formed by at least two cross bars (2) which are parallel to each other and are vertically connected between the uprights (1); at least one hook (3) is arranged at the top of the hanging ladder body; the hooks (3) are opened downwards. Due to the connection between the hanging ladder bodies, the continuous hanging ladder can achieve any length and meets the requirements of various occasions and environments; as the long hanging ladder can be disassembled into minimum hanging ladder body units after use, the continuous hanging ladder is convenient to transport and move; distance posts are arranged at the side, same to the side of the hooks, of the hanging ladder body, so that a distance can be kept between the hanging ladder body and a steel structure item and is convenient for a worker to stop over; and the continuous hanging ladder has a simple structure and is economical, practical and convenient.
Description
Technical field
The present invention relates to a kind of instrument in a kind of Pre-tensioned Steel Structures, specifically refer to the splice hanging ladder in welding for steel structure technique.
Background technology
In recent years, steel building had clear superiority compared to brick-and-concrete buildings in environmental protection, energy-conservation, efficient, factorial praluction etc.The heavy construction such as Jin Mao Tower, Jing Guang Center, Pekinese of the DiWang Building that Shenzhen is high 325 meters, high 421 meters of PVG all have employed steel work, the provinces and cities such as Beijing, Shanghai, Shandong have started to carry out steel house pilot, wherein, Jin Chen apartment in Beijing has been listed in Ministry of Construction's steel structure of housing system demonstration project.Nigh-level synthesis people of common occurrence expect that 21 century is century of metal construction, and steel work will become the spine in new building epoch.The mankind bring into use the pig iron from seventies the 17th century, and 19 beginnings of the century brought into use wrought iron to build bridge and house, the history of steel work development than reinforced concrete structure develop with a long history, its vitality is also more and more stronger.In the U.S., low-rise building such as the non-residential construction market below two floors existing more than 70% is structural metal goods.The whole world is so far in completed 101 building super highrise buildings, reinforced concrete structure 16 building, pure steel structure 59 building, multi-form steel concrete mixed structural 27 building; Can find out that the development of steel work will impel builing industry, metallurgical industry, mechanical industry, auto industry, agricultural, petroleum industry, business, transportation to be developed rapidly.Being made as main structure with steel, is one of main building construction types.The feature of steel is that intensity is high, large from heavy and light, rigidity, thus for building large span and superelevation, extra-duty building is suitable especially; Material homogeneity and isotropism good, belong to perfect elastic body, meet the basic assumption of common engineering mechanics most; Material plasticity, good toughness, can have moderate finite deformation, can bear dynamic loading well; Construction period is short; Its industrialization degree is high, can carry out the high Virtual production of mechanization degree; Machining accuracy is high, efficiency is high, good leak tightness, therefore can be used for building gas tank, oil tank and transformer etc.
In the industries such as Steel Structure Installation, particularly in the installation process of steel work, because steel work is all by crane lifting, need when contact to carry out the simple steady jobs in advance such as spot welding to parts.Because parts are in by the state lifted, its aloft and unstable, therefore, the safety of workman is the most scabrous problem in lifting work.
Summary of the invention
The object of the present invention is to provide the splice hanging ladder in welding for steel structure technique, so that in the hoisting process of steel work, facilitate that workman's is upper and lower, ensure the life security of workman simultaneously.
Object of the present invention is achieved through the following technical solutions:
Splice hanging ladder in welding for steel structure technique, comprise and to be parallel to each other by two parallel columns and at least two and to be vertically connected on the hanging ladder body that the cross bar between column forms, at least be provided with a hook at the top of described hanging ladder body, Open Side Down for described hook.Hanging ladder arranges the hook that Open Side Down, can make to be connected by hook between hanging ladder body, according to Len req, hanging ladder can be connected arbitrarily, with the needs of satisfied construction.
As a further improvement on the present invention, the plane orthogonal at described hook place is in hanging ladder body.So just can make to maintain a certain distance between hanging ladder body and steel structure object, facilitate workman to stop on the cross bar of hanging ladder body.
As a further improvement on the present invention, described hook is two, and is connected to two column tops of hanging ladder body.More stable after two hooks can make hanging ladder body hang, prevent it from swinging, make workman's amplitude of fluctuation reduction aloft, the security risk of workman is reduced.
As a further improvement on the present invention, described hanging ladder body is also provided with at least two distance posts, described distance post and hook are in the same side of hanging ladder body.So, be not only convenient to the connection between hanging ladder, and make the distance between hanging ladder body and object keep certain value, more convenient workman stops over.
Described distance post is vertical with hanging ladder body.
The present invention compared with prior art, has following advantage and beneficial effect:
Splice hanging ladder in 1 welding for steel structure technique of the present invention, by the connection between hanging ladder body and hanging ladder body, can reach arbitrary length, be suitable for the needs of multiple place, environment;
Splice hanging ladder in 2 welding for steel structure techniques of the present invention, after being used to complete, can be split as minimum hanging ladder body unit by long hanging ladder, is therefore convenient to transport, circulation;
Splice hanging ladder in 3 welding for steel structure techniques of the present invention, hanging ladder body is provided with distance post with hook homonymy, can makes to keep at a distance between hanging ladder body and steel work object, facilitate workman to stop over;
Splice hanging ladder in 4 welding for steel structure techniques of the present invention, structure is simple, economical and practical, convenient and practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Mark and corresponding component title in accompanying drawing:
1-column, 2-cross bar, 3-links up with, 4-distance post.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
Embodiment
As shown in Figure 1, the present invention includes hanging ladder body, hanging ladder body by two parallel posts 1 and multiple be parallel to each other and the cross bar 2 be vertically connected between column 1 form, at the top of hanging ladder body, two hooks 3 are installed, link up with vertical with hanging ladder body, hanging ladder body with hook 3 homonymies are provided with the distance post 4 that two is a pair, and having some posts 4 of adjusting the distance, distance post 4 is perpendicular to hanging ladder body.
As mentioned above, just the present invention can be realized well.
