Description
Technical Field
The utility model relates to a steel constructs building technical field, specifically is a girder steel with beta structure.
Background
The steel structure building is a novel building system, breaks through the industrial boundary lines among the house area industry, the building industry and the metallurgical industry, and is integrated into a new industrial system, namely the steel structure building system which is generally seen by people in the industry. Compared with the traditional concrete building, the steel plate or the section steel replaces reinforced concrete, so that the steel structure building has higher strength and better shock resistance. And because the components can be manufactured in factories and installed on site, the construction period is greatly reduced. Because the steel can be repeatedly used, the construction waste can be greatly reduced, and the steel is more environment-friendly, so the steel is widely adopted by all countries in the world and is applied to industrial buildings and civil buildings. The steel structure building generally adopts section bars such as I-steel, U-shaped steel, rectangular pipe to set up the skeleton in house, and the girder steel on roof generally adopts the spiro union mode to install, owing to operate inconveniently and the girder steel is more at the roof, consequently installs the time that expends one by one to the efficiency that leads to the construction is lower.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a girder steel with beta structure to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a girder steel with beta structure, includes connecting seat and back timber, the upper end of back timber is articulated through the round pin axle with the connecting seat, the back timber is equipped with two and about the vertical central line symmetry of connecting seat, the middle part welding of connecting seat has the card rail that runs through, the inboard of back timber articulates through the round pin axle has the bracing piece, the other end of bracing piece is equipped with the gear, the pivot that the middle part fixedly connected with of gear runs through, the pivot is rotated with the link of U-shaped and is connected, meshing between two gears.
Preferably, the top beam is made of U-shaped steel by cutting, the cross section of the clamping rail is U-shaped, and a through round hole is formed in the side face of the clamping rail.
Preferably, the side welding of gear has the pin, be equipped with curved spacing hole on the link, the pin runs through spacing hole and rather than sliding connection.
Preferably, the end of the pin is provided with an external thread and is screwed with a fastening nut, and the limiting hole takes the rotating shaft as the center of a circle.
Preferably, the connecting seat is of a shell structure with an open lower side, and the connecting seat is made of metal plates in a welded mode and is 5-8 mm thick.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses the upper end of two back timber is articulated with the connecting seat, can draw close each other and realize packing up foldingly, reduces area, convenient transportation. During construction, the steel beams can be installed on the ridge middle beam at equal intervals on the ground, the angle of the top beam is adjusted to be consistent, then the crane is used for lifting the whole body to be built, modularized operation is achieved, and construction efficiency can be effectively improved.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a girder steel with beta structure, includes connecting seat 1 and back timber 2, and the upper end of back timber 2 is articulated through the round pin axle with connecting seat 1, and connecting seat 1 is the open shell structure of downside, and connecting seat 1 adopts the metal sheet welding to make and thick 5 ~ 8mm of board, and connecting seat 1's effect is as an organic whole with the girder steel connection of ridge both sides.
The inboard of back timber 2 has bracing piece 3 through round pin axle is articulated, the other end of bracing piece 3 is equipped with gear 6, the pivot 10 that the middle part fixedly connected with of gear 6 runs through, pivot 10 rotates with the link 5 of U-shaped and is connected, mesh between two gears 6, can ensure that two back timber 2 keep synchronous opening and shutting, the side welding of gear 6 has pin 8, be equipped with curved spacing hole 7 on the link 5, pin 8 runs through spacing hole 7 and rather than sliding connection, the tip of pin 8 is equipped with external screw thread and spiro union has fastening nut 9, spacing hole 7 uses pivot 10 as the centre of a circle.
The working principle is as follows: the upper ends of the two top beams 2 are hinged to the connecting seat 1, so that included angles between the two top beams 2 can be freely adjusted, the included angles can be folded by drawing close each other, the occupied area is reduced, and transportation is facilitated. Have bracing piece 3 in the inboard of back timber 2 is articulated, and the lower extreme of bracing piece 3 sets up gear 6 to two gear 6 meshes, consequently two back timbers 2 can keep opening and shutting in step, conveniently carry out angle regulation, and after fastening nut 9 screwed up, the contained angle of two back timbers 2 is fixed.
