The utility model discloses a stable roof structure which comprises a group of steel columns 3 and wind-resistant columns 1, wherein the steel columns are vertically arranged on the ground. As shown in fig. 2, a corner post 31 is coaxially disposed in the steel post 3, and the bottom end of the corner post 31 is inserted into the bottom surface, and the insertion depth is 3±1.5m. The steel columns 3, the wind-resistant columns 1 and the corner columns 31 are all preferably made of Q355B steel by welding, wherein the section specification of the wind-resistant columns 1 is preferably H650 x 300 x 12 x 18mm, the section specification of the corner columns 31 is preferably H300 x 250 x 6 x 8mm, and the section specification of the steel columns 3 is preferably H800 x 450 x 14 x 22mm.

The roof unit 2 is arranged at the top of the wind-resistant column 1, specifically, the steel column and the top of the wind-resistant column 1 are fixedly connected with the roof unit 2 through end span steel frames, temporary span steel frames and the like, and each roof unit 2 is arranged at an angle with the steel column and the wind-resistant column 1. The end span steel frame and the temporary span steel frame both comprise an I-beam and reinforcing ribs arranged on two sides of a web plate of the I-beam, and a group of reinforcing ribs for enhancing structural stability are arranged on the reinforcing ribs.

As shown in fig. 2 to 3, each of the roof units 2 includes a group of steel beams 21 arranged in parallel, a group of tie bars 22 arranged perpendicular to the steel beams 21, and a horizontal support 23 connecting the steel beams 21 and the tie bars 22. The steel beams 21, the tie bars 22 and the horizontal supports 23 are fixedly connected in pairs, so that the roof unit 2 is more stable in structure. In the present utility model, the steel beam 21 is preferably made of Q355B material and is formed by welding H-shaped steel; the tie bars 22 and the horizontal supports 23 are made of Q235B material, wherein the cross section diameter of the tie bars 22 is preferably 159 x 6mm, and are made of seamless steel tubes; the cross-sectional diameter of the horizontal support 23 is preferably 100 x 6mm and is made of hot rolled angle steel.

Further, as shown in fig. 1 or 3, the horizontal support 23 is disposed in an X-shape; at least one horizontal support 23 is arranged between two adjacent tie bars 22, and the included angle between the horizontal support 23 and the tie bars 22 is not less than 35 degrees and not more than 45 degrees. In order to make the roof unit 2 more stable, the angle between the tie bars 22 and the horizontal support 23 is preferably set to 40 ° in the present utility model. So that when a force is applied to the roof unit by a cross wind in the north-south direction, the angle of 40 degrees between the tie bars 22 and the horizontal supports 23 can be opposed by the tie bars; the angle between the steel beam 21 and the horizontal support 23 is 50 ° to effectively resist the cross wind from the X-axis direction of the roof unit 2 (the width direction of the roof unit 2), so that setting the angle between the tie bar 22 and the horizontal support 23 to 40 ° can increase the wind resistance of the roof unit 2, and stabilize it more.

As shown in fig. 3, the tie bars 22 include a first tie bar 221 disposed in the middle of the roof, a second tie bar 222 disposed above the wind resistant column 1, and a side tie bar 224 disposed at the purlin of the roof, which are parallel to each other. The second tie bars 222 are located on both sides of the first tie bars 221 with at least two of the horizontal supports 23 therebetween; the side tie bars 224 are located outside the second tie bars 222 with at least one of the horizontal braces 23 disposed between the second tie bars 222.

Further, the tie bars further include a third tie bar 223, and the third tie bar 223 is disposed perpendicular to the first tie bar 221, the second tie bar 222, and the side tie bars 224. The third tie bar 223 is located at the connection position of two adjacent horizontal supports 23 and is fixedly connected with the horizontal supports 23; the third tie rods 223 are disposed parallel to the steel beam 21. The intersection of the horizontal supports 23 connecting the side tie bars 224 with the second tie bars 222 is connected to the third tie bars 223. In the conventional roof structure, as shown in fig. 1, since the third tie bar 223 is not provided and the first tie bar 221 and the second tie bar 222 are connected by only one horizontal support 23, when the interval between two adjacent steel beams 21 is large and the interval between the first tie bar 221 and the second tie bar 222 is small, the angle between the horizontal support and the first tie bar 221 and/or the second tie bar 222 is smaller than 40 °, and when the force is applied to the roof unit 2 by the crosswind in the east-west direction, the steel beams 21 and the horizontal support 23 apply the force to the tie bars, so that the first tie bar 221 and the second tie bar 222 are easily bent, thereby causing damage to the roof unit 2. The improvement of the present utility model herein may be illustrated with reference to fig. 3, by increasing the third tie bar 223 and the horizontal support 23 so that the angle between the horizontal support 23 and the first tie bar 221 and/or the second tie bar 222 increases, when the horizontal support 23 applies a force to the first tie bar 221 and/or the second tie bar 222 after the east-west direction cross wind comes, the force will be transmitted to the third tie bar 223 through the horizontal support 23, and further transmitted and dispersed to other directions through the third tie bar 223, so as to effectively reduce the acting force to the first tie bar 221 and the second tie bar 222, and further reduce the deformation of the first tie bar 221 and the second tie bar 222, and prolong the service life of the roof unit 2.

The number of the third tie bars 223 may be adjusted according to the distance between two parallel steel beams and the interval between the first and second tie bars 221 and 222 such that the angle between the horizontal support and the first tie bar 221 is 40 °. The number thereof is not particularly limited herein.

As shown in fig. 4, the horizontal support 23 is composed of two steel pipes which are pivotally arranged; a locating pin 231 is pivoted on one of the steel pipes, and a notch is formed in the locating pin 231; the other steel pipe is provided with a protruding block 232 protruding out of the outer surface of the other steel pipe, and the notch is matched with and clamped with the protruding block 232. The quick installation and fixation of the horizontal support 23 are realized through the structure of the locating pin, so that two steel pipes on the horizontal support 23 can be quickly rotated to a required angle and fixed, and the progress of a building is quickened. In addition, two positioning pins are preferably disposed on each horizontal support 23, and the two positioning pins preferably form an included angle of 90 ° after installation, so as to fix two steel pipes located on one horizontal support 23, and the function of the two steel pipes is equivalent to that of a reinforcing rib, so that the horizontal support 23 is not easy to deform in the case of transverse wind. Of course, in other embodiments, two steel pipes disposed in a crossing manner on the horizontal support 23 are fixedly connected by welding or other manners, and the two steel pipes are disposed to be movably connected in the present utility model, so that the installation flexibility can be provided and the rapid installation can be conveniently realized.
