Description

The combined steel shell system

[technical field] the utility model belongs to light steel architectural structural system, the combined steel shell system that the particularly a kind of C of application shaped steel is beam, post.

The lightweight steel construction that [background technology] China rises the sixties mainly is the building construction that constitutes with the triangular roof truss formula slope portal frame that round steel, little angle steel are formed.Though this light section steel structure obtains certain application, its watt material itself exists defectives such as fastness and durability deficiency, and is not resolved all the time.Light-duty flat slope roofings such as profiled sheet that introduce the nineties and space plate, the sectional dimension of its steel roof structure and weight all significantly reduce, thereby light section steel structure is enlarged on the range of application more more.

The light steel frame in the world can be divided into 5 kinds by steel cross section and shell system at present:

1, H shaped steel beam column supports and to add light steel and go along with sb. to guard him shell system, is called for short the H+H shell system.

2, C shaped steel beam column supports and to add light steel and go along with sb. to guard him shell system, is called for short the C+C shell system.

3, square steel is a post, and U shaped steel is the support system of beam, is called for short +U shell system.

4, square steel is a post, and H shaped steel is the support frame system of beam, is called for short +H shell system.

5, cold rolling light steel frame system.

The characteristics of various steel structure framework system:

1, H shaped steel: can be divided into pad and roll type and high-frequency welding type, the manufacturer of domestic H shaped steel is numerous, can satisfy the needs of steel building development fully, it is the preferred material of domestic development steel building of present stage (transitional period), shortcoming is that the steel consumption amount is big, the node processing difficulty, the essential welding method that adopts is processed.

2, U shaped steel: cold roll forming, thickness is 1.6-8mm, height 50-452mm is of little use in American-European market, and it is the preferred material of light steel dwelling house in Japan, advantage is that the steel consumption amount is few, shortcoming is the cross section instability, and the worry of distortion is arranged, in this class section bar of state-owned indivedual manufacturer production, but few and lack corresponding use experience because of the market consumption, also be difficult at present compete with H shaped steel.

3, C shaped steel: cold roll forming, thickness is 1.5-6mm, highly it is the main material of using that light steel building supports beam column the America and Europe for 73-38mm, conduct is supported with a small amount of application in Japanese light weight steel structure, in China this class section bar of manufacturer production is arranged also, but because of lacking corresponding use experience, it seldom is used for beam column in the support of light steel building, but it is the main attack research direction of light weight steel structure with steel.

4, square steel: cold roll forming, high-frequency welding thickness is 1.5-8mm, the length of side is 20-200mm, it is the first-selection material of light steel building in Japan, and the America and Europe does not adopt very much, and advantage is that the cross section is stable, the node arrangement convenience, shortcoming is that the steel consumption amount is big, a little less than the pair that is threaded, domesticly seldom adopts this supporting system.

5, cold rolling light steel frame: cold roll forming, as the load-bearing keel, its thickness is generally 0.84-2.46mm, the length of side is 60-305mm, Japan seldom adopts this supporting system, mainly be that some American-European manufacturers are adopting, domestic non-bearing (partition wall and furred ceiling) lightgage steel joist production capacity is very big, but the producer of energy production load-bearing lightgage steel joist seldom.

In sum, at present in the light steel building system of China, nearly all steel work all adopts the light steel system of H type, promptly substitutes the wooden frame post of Chinese traditional brick wood building or the reinforced concrete beam column of modern architecture with H shaped steel, though the technology span changes little like this, help existing design and construction personnel operation, shortcoming is that the steel consumption amount is big, the node processing difficulty, and the essential welding method that adopts is processed, and run in the opposite direction with the world's light steel Building technology trend, be unfavorable for applying lightweight body of wall technology.

[summary of the invention] the purpose of this utility model is: the combined steel shell system that a kind of C shaped steel is provided is beam, post, it can avoid above-mentioned deficiency.

The purpose of this utility model is achieved in that the steel frame system is connected and composed by following seven parts:

1, post: form I-shaped by a pair of C shaped steel;

2, beam: form I-shaped by a pair of C shaped steel;

3, wall beam: C shaped steel;

4, purlin: C shaped steel;

5, eaves support: be used for being connected of eaves place, house post and beam, the eaves support can be made into 5 ° ~ 15 ° angle by roof pitch.

6, ridge support is used for the connection between house ridge place beam and the beam, and the ridge support can be made into 5 ° ~ 15 ° angle by roof pitch.

7, angle type plate: be used for being connected between premises beam and purlin, post and the wall beam.Two right angle faces have respectively two with the matching of the corresponding semi-circular groove of beam, post, purlin and wall beam, and be furnished with the corresponding bolts hole.

Mounting method is: at first, foundation mounts, eaves support are sandwiched in the middle of the post, and wall beam are placed between post and the post and flange is downward, and mix the dihedral plate and tighten with bolt; Secondly, the ridge support is sandwiched in the middle of the beam, and beam is connected with post by the eaves support and tightens with bolt; At last, purlin is placed in the middle of the Liang Yuliang, and flange is connected with beam by angle type plate towards the roof incline direction, and tighten with bolt.

Promptly formed the combined steel shell system by above step installation, the whole erection process is without any need for heavy equipment, and soldering equipment, Gu but all-weather construction (even also can construct winter) shortens the duration of whole engineering, steel using amount is few, and node is easily handled, and has reduced construction costs to greatest extent.
