DETAILED DESCRIPTION

The present application is further described in detail below in conjunction with Figures 1 to 4.

The embodiment of the present application discloses a protective truss, which is applied to steel structure buildings, especially steel structure buildings such as factories, to form the building facade, and the facade is formed by transverse corrugated steel plates, and the transverse corrugated steel plates are longitudinally supported to improve the structural stability of the facade, thereby improving the wind and rain resistance of the facade.

Referring to FIG2 , in order to further understand the present application, the working principle of the steel structure building applicable to the present embodiment is first described. The steel structure building includes a wall panel 1 forming the top facade and a truss for supporting the wall panel 1. The wall panel 1 is paved with transverse corrugated steel plates to improve the shear yield strength. The truss includes an upper wall beam 2, a lower wall beam 3 and a plurality of straight web members 5. The upper wall beam 2 and the lower wall beam 3 are parallel to each other. A plurality of upper wall beams 2 are connected end to end in sequence to form a plane layer frame of the building. A plurality of lower wall beams 3 are connected end to end in sequence to form a frame parallel to the plane where the upper wall beam 2 is located. The upper wall beam 2 and the lower wall beam 3 are preferably hot-rolled steel, that is, channel steel or I-beam. The present embodiment uses a channel steel structure as a demonstration. The wall panel 1 is a transverse corrugated steel plate connected to the upper wall beam 2 and the lower wall beam 3 by welding. A plurality of straight web members 5 are arranged in an array between the upper wall beam 2 and the lower wall beam 3 . The straight web members 5 are vertically arranged between the upper wall beam 2 and the lower wall beam 3 , and two ends of the straight web members 5 are welded to the upper wall beam 2 and the lower wall beam 3 respectively.

2 and 3 , in other embodiments, the straight web member 5 can also be made of hot-rolled steel. In this embodiment, the straight web member 5 is configured as a rectangular hollow steel structure. Specifically, the lower wall beam 3 is connected to the bottom support structure. When the lower wall beam 3 is configured as a channel steel structure, the notch of the lower wall beam 3 faces upward.

Referring to Fig. 2 and Fig. 3, further, the truss also includes a plurality of connection seats 6, which are arranged perpendicular to the length direction of the lower wall beam 3, and the connection seats 6 cross the notch of the lower wall beam 3 and are connected to the edges of the notch on both sides of the upper wall of the lower wall beam 3. The connection seats 6 can be connected to the lower wall beam 3 by welding or other methods. The straight web member 5 is connected to the lower wall beam 3 at intervals through the connection seats 6. The upper surface of the connection seat 6 is a continuous plane, and the straight web member 5 can be vertically connected to the edge of the connection seat 6, so that the outer wall of the straight web member 5 and the outer wall of the lower wall beam 3 are on the same vertical plane, so that the wall panel 1 can contact the straight web member 5 and the lower wall beam 3 at the same time. Due to the requirements of steel structure construction, the notch of the upper wall beam 2 is generally in the same direction as the notch of the lower wall beam 3. Therefore, the end of the straight web member 5 away from the lower wall beam 3 can be directly connected to the upper wall beam 2, and it is not excluded that in other embodiments, based on other structural considerations, the straight web member 5 is connected to the upper wall beam 2 through the connection seat 6 to achieve the above-mentioned effect. Therefore, the upper wall beam 2, the straight web member 5 and the outer wall of the lower wall beam 3 are all in the same vertical plane, so that the contact area between the wall panel 1 and the truss is as large as possible, providing longitudinal support for the wall panel 1, making the wall panel 1 more stable when affected by external forces.

Referring to Fig. 2 and Fig. 3, further, the connection seat 6 can be a sheet steel structure or a channel steel structure, etc., and only needs to ensure that the straight web member 5 can be connected to the edge of the lower wall beam 3 and the upper wall beam 2, and no specific shape restriction is made. When the connection seat 6 is set as a channel steel structure corresponding to the lower wall beam 3, through the cooperation of the connection seat and the lower wall beam, a certain length of cantilever of the connection seat can be achieved, and the welding point area of the connection seat and the wall panel is increased.

Referring to Fig. 2, further, since the building roof needs to be tilted to both sides, the wall panels 1 at both ends of the top outer wall need to be adaptively adjusted to a triangular structure. Therefore, in the prior art, an auxiliary rod 7 is tilted and erected above the upper wall beam 2, and two auxiliary rods 7 are arranged in cooperation with the upper wall beam 2 to form a triangular structure. A plurality of web bars 4 are also arranged vertically between the upper wall beam 2 and the auxiliary rod 7 as support, and the enclosure is cut into a triangular structure and welded to the auxiliary rod 7 and the outer side of the upper wall beam 2. However, in this implementation, at least two straight web bars 5 are arranged vertically and spaced above the upper wall beam 2, and the length of the plurality of straight web bars 5 gradually increases from both sides to the center, and the straight web bars 5 are connected to the triangular structure wall panels 1 at the edge in cooperation with the upper wall beam 2. Thereby reducing the setting cost and construction steps of the auxiliary rod 7. Reducing the cost and construction steps in the construction of the overall steel structure building.

Referring to Fig. 3 and Fig. 4, further, the straight web bar 5 includes a rod body 51, and a connecting sleeve 521 and a connecting bolt 53 are arranged in the rod body 51. The connecting sleeve 521 is perpendicular to the length direction of the rod body 51, and a plurality of connecting sleeves 521 are arranged at intervals. The connecting bolt 53 can be horizontally passed through the wall panel 1 and the outer wall of the rod body 51 to the connecting sleeve 521, and the connecting sleeve 521 is threadedly connected with the connecting bolt 53. Through the cooperation of the connecting bolt 53 and the connecting sleeve 521, the wall panel 1 is connected to the straight web bar 5, so as to facilitate the reinforcement of the wall panel 1 and facilitate the subsequent removal of the wall panel 1.

3 and 4 , further, a shock absorbing ring 531 is sleeved on the connecting bolt 53 . The shock absorbing ring 531 is annular carbon steel and has a notch. The shock absorbing ring 531 is disposed between the nut of the connecting bolt 53 and the enclosure.

3 and 4, further, the straight-abdomen rod 5 further includes a central implant 52, the rod body 51 is a hollow tube with a rectangular cross-section, and the central implant 52 is a long strip rod body 51 that passes through the rod body 51 along the length direction of the rod body 51. The cross section of the central implant 52 is preferably an I-shaped cross section, and the internal space of the rod body 51 is filled by the central implant 52, thereby increasing the structural strength of the rod body 51.

3 and 4, further, the outer wall of the rod body 51 is provided with a connection hole 511 for the connection bolt 53 to pass through, and the connection sleeve 521 is arranged on the implant 52. The connection sleeve 521 can be inserted into the rod body 51 along with the implant 52. After reaching a suitable position, the connection sleeve 521 corresponds to the position of the connection hole 511, and the connection bolt 53 can pass through the connection hole 511 to the connection sleeve 521 and be threadedly connected with the connection sleeve 521. The connection sleeve 521 is arranged on the implant 52 to facilitate production and reduce processing costs.

Referring to Fig. 3 and Fig. 4, further, the outer wall of the rod body 51 is provided with a first limiting hole 512 connected to the internal space, the implant 52 is provided with a second limiting hole 522 corresponding to the position of the first limiting hole 512, and a positioning member 54 is passed through the first limiting hole 512 to the second limiting hole 522. The positioning member 54 is a rod-shaped structure. When the implant 52 is inserted into the rod body 51 and the first limiting hole 512 and the second limiting hole 522 correspond, the positioning member 54 passes through the first limiting hole 512 from the outside to the inside to the second limiting hole 522, thereby limiting the implant 52 from being separated from the rod body 51, increasing the structural stability of the straight-belly rod 5, and making the connection sleeve 521 correspond to the connection hole 511.

3 and 4, further, in other embodiments, a reinforcing rod may be provided on the outer wall of the straight web member 5, the reinforcing rod being provided obliquely, one end of the reinforcing rod being connected to the outer wall of the straight web member 5, and the other end being connected to the upper surface of the connecting seat 6, so that the reinforcing rod cooperates with the straight web member 5 and the connecting seat 6 to form a triangular structure. This increases the connection between the straight web member 5 and the connecting seat 6, and at the same time increases the support of the straight web member 5 by the reinforcing rod when it is subjected to a lateral force perpendicular to its length direction, thereby improving the structural stability.

The implementation principle of a protective truss in the embodiment of the present application is:

By adding a connecting seat 6 at the lower wall beam 3, and the upper surface of the connecting seat 6 is a continuous plane, the straight web member 5 can be connected to the edge of the connecting seat 6, so that the lower wall beam 3, the upper wall beam 2 and the outer wall of the straight web member 5 are all in the same vertical plane. When connecting the wall panel 1, the wall panel 1 can be connected to the straight web member 5 to increase the longitudinal support, so as to improve the structural stability of the wall panel 1.

At the same time, due to the provision of the straight web members 5 , when a triangular enclosure is provided on the roof, the part of the wall panel 1 can be directly supported by the straight web members 5 , thereby reducing the cost and steps of providing the auxiliary rods 7 .

In addition, through the cooperation of the connecting bolts 53 and the connecting sleeves 521, the wall panel 1 and the straight web bar 5 can be connected more conveniently, and the subsequent removal is convenient.

The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
