In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, terms appearing as "mounted," "connected," and "connected" are to be construed broadly, e.g., as being fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

As shown in fig. 1 to 3, the framework assembly for a metal roof tent comprises

A horizontal square upper frame;

the oblique beam is a hexagonal oblique beam formed by sequentially connecting a bottom plate 31, a first side plate 32, a second side plate 33, an upper plate 34, a third side plate 35 and a fourth side plate 36 end to end;

For a metal top tent, taking a quadrilateral upper frame as an example, the metal top tent is generally provided with four oblique beams 3, the oblique beams are obliquely directed downwards from any corner of the upper frame 1, a middle beam is arranged between the two oblique beams, the middle beam and the oblique beams are fixed through small beams 4, and a metal cover plate is fixed between the oblique beams and the middle beam 2 through bolts.

To current square tube formula sloping design, the metal covering plate contacts for a right-angle side and the metal covering plate contact of sloping with the contact of sloping, for facial line contact cooperation, the screw is by being higher than the right-angle side part with the tight fixed to sloping of metal covering plate spiral shell, be the space between the metal covering plate that is higher than the right-angle side part and the square tube formula sloping, and the space is great, so make unable laminating between metal covering plate and the square tube formula sloping, take place to warp at the tight in-process metal covering plate of screw spiral shell, lead to the printing opacity, the scheduling problem leaks, and still because of the existence in clearance, the assembly process is not convenient.

Based on the above problems, in the above solution of the present invention, an inclined plane is formed by setting an included angle between the second side plate and the upper plate to 164 ± 2 degrees, so that when the metal cover plate is assembled with the oblique beam, an end of the metal cover plate can be attached to the second side plate, the metal cover plate is screwed and fixed to the second side plate by a screw or a screw, and the other side of the metal cover plate is fixed to the third side plate in the same manner.

In the above scheme, because the oblique beam is inclined downward, when the square tube is adopted, referring to fig. 2, because the oblique beam is obliquely arranged, the distance between the side wall and the middle beam of the oblique beam is gradually increased from the length direction of the middle beam inclined downward from the upper frame, and because the oblique beam and the middle beam both have a certain thickness, the change rate of the distance between the upper edge of the side wall of the oblique beam and the upper edge of the middle beam in the length direction of the middle beam is greater than the change rate of the distance between the lower edge of the side wall of the oblique beam and the lower edge of the middle beam; in order to ensure smooth installation of the middle beam and the side wall of the oblique beam and improve installation firmness, in the prior art, when the matching end surfaces of the small beam and the middle beam are kept to be vertical cuts, the matching end surfaces of the small beam and the oblique beam are obliquely cut so as to meet the assembly requirements of the small beam, the side wall of the oblique beam and the side wall of the middle beam, and the oblique cutting and conventional cutting equipment needs to be cut off and cut off in multiple steps (see the end surface of fig. 4, the matching end surface 10 is matched with a non-vertical surface) and needs to polish the end surfaces, so that the production efficiency is low, the manufacturing cost is high, direct oblique cutting equipment does not exist at present, and even if the equipment exists, the equipment can not be suitable for production and manufacturing of metal top tent enterprises due to high manufacturing cost. Therefore, in the technical scheme of the invention, the included angle between the first side plate and the bottom plate is set to be 106 +/-2 degrees, and the included angle is measured by 30 degrees based on the inclined angle between the oblique beam and the upper frame, so that the end surface of the vertically cut small beam can completely meet the assembly requirement of the end surface of the small beam and the side wall of the oblique beam.

Through setting up the contained angle between first curb plate and the second curb plate into 90 degrees for the body can keep the highest intensity on the whole, has strengthened the bearing capacity of metal top tent.

The tube body is a hexagonal tube body and has an axisymmetric structure,

wherein, the body is the steel pipe.

In the scheme, the middle beam and the upper frame are fixedly connected through L-shaped angle steel 6, the oblique beam is installed on the corner of the upper frame, so that the oblique beam and the upper frame are fixedly connected through V-shaped L-shaped angle steel, and the matching section of the oblique beam and the V-shaped L-shaped angle steel 5 is in a V shape.

The middle beam, the oblique beam and the corresponding angle steel are fixedly welded, and the angle steel and the upper frame are fixedly welded.

The welding fixation can also adopt screw fixation.

It will be apparent to those skilled in the art that modifications and equivalents may be made in the embodiments and/or portions thereof without departing from the spirit and scope of the present invention.
