TECHNICAL FIELD
[0001] The utility model belongs to door type steel frame technical field especially relates to a door type steel frame plant steel structure device. BACKGROUND
[0002] The door type steel frame structure plant is one kind of steel structure plant, adopts multiple door type steel frame structures as the main structure, then fixes a large number of roof purlin, wall purlin after reinforcing between each door type steel frame structure, and can constitute the plant structure after laying the upper panel.
[0003] In the processing, a large number of support structures, including such as support beam rod, need to be welded between the door type steel frame structures. The structural strength between the door type steel frame structures is increased by this mode.
[0004] Therefore, in the actual operation process, not only the installation is complicated, but also the structural stability cannot be guaranteed due to a large number of welded support structures. Specifically, the welding effect of all support structures cannot be guaranteed during the welding process. Therefore, after using the steel structure for a certain period of time, the steel structure needs to be regularly checked, and the structure with insufficient welding needs to be reprocessed, such as the support structure with cracks in the welding position needs to be re-welded.
[0005] Therefore, the traditional steel structure plant site construction steps are too many and too complicated.
[0006] For the door type steel frame structure plant, if a reinforcing structure is formed by a convenient installation and welding-free mode, not only can the disadvantages caused by welding be greatly reduced, but also the prefabricated production of the steel structure can be realized. After production, the steel structure is transported to the site, and the prefabricated structure is assembled. Not only is the installation efficiency higher and the installation workload lower, but also the technical disadvantages of the subsequent steel structure needing a large amount of maintenance cost due to welding quality in the traditional welding mode operation can be effectively avoided.

[0038] Example 1
[0039] like Figures 1-5 As shown, a portal steel frame factory building steel structure device includes a portal steel beam mechanism, and the grooves of the portal steel beam mechanism constitute the main structure of the entire factory building steel structure.
[0040] The portal steel beam structure comprises several portal steel beam units 2, which are supported by several tension bracing structures. The stability of the steel structure is increased by the tension bracing structures, and the prefabrication design of these structures significantly improves installation efficiency. Furthermore, this method effectively avoids welding for reinforcement, thus resolving the drawback of inconsistent welding quality in all support structures, which could lead to secondary reinforcement required if cracks occur at the weld points.
[0041] The door type steel beam unit 2 comprises an upper roof beam frame structure, and vertical beam frames 24 are detachably installed at the front and rear ends of the upper roof beam frame structure; the counter-bracing structure is supported and installed on the adjacent vertical beam frames 24; and the upper roof beam frame structure and the vertical beam frames 24 are pulled tight through the diagonal bracing structures arranged on the two sides.
[0042] Specifically, the upper roof beam frame structure comprises an upper roof beam frame 21, and the upper roof beam frame 21 comprises trapezoidal beam frame portions 211 symmetrically arranged front and rear; the trapezoidal beam frame portions 211 are integrally formed structures.
[0043] A plurality of mounting screws are fixedly connected to the outer side walls (specifically, the front and rear side walls are welded with mounting screws) of the trapezoidal beam frame portions 211, and the mounting screws are fastened and installed on the vertical beam frames 24, specifically, the vertical beam frames 24 are provided with matching through holes, and the mounting screws are fastened with upper nuts after penetrating through the through holes.
[0044] The counter-bracing structure comprises a counter-bracing frame, and the counter-bracing frame is provided with a plurality of counter-bracing connecting portions, and the counter-bracing connecting portions are installed on the adjacent vertical beam frames 24.
[0045] Specifically, a pair of the counter-bracing structures are installed between the adjacent vertical beam frames 24 and are arranged in an upper and lower spaced manner.
[0046] The counter-bracing frame comprises an X-shaped counter-bracing frame 25, and the X-shaped counter-bracing frame 25 is provided with four counter-bracing connecting portions (the shape of the X-shaped counter-bracing frame determines the counter-bracing connecting portions).
[0047] Meanwhile, the counter-bracing connecting portion comprises a first U-shaped mounting seat 251 welded on the X-shaped counter-bracing frame 25, and the vertical beam frame 24 is welded with a first lug 242 corresponding to the first U-shaped mounting seat 251, and the first U-shaped mounting seat 251 and the first lug 242 are fixedly connected through a pin shaft screw, and the pin shaft screw is fastened with an upper nut after penetrating through the first U-shaped mounting seat 251 and the first lug 242.
[0048] In this way, the X-shaped counter-bracing frame 25 has four counter-bracing points, and the vertical beam frames 24 on the two sides are counter-braced at four corners. In actual working process, two counter-bracing structures are installed between each pair of adjacent vertical beam frames 24, so that there are totally eight counter-bracing points. This way not only greatly improves the structural strength between the adjacent door type steel beam units 2, but also realizes that the X-shaped counter-bracing frame 25 is directly installed in the installation process. This way has high counter-bracing stability, and the subsequent welding position cracking that needs secondary reinforcement does not exist in the traditional welding way.
[0049] Embodiment 2
[0050] As Figures 1-5As shown, the embodiment is based on the structure of Embodiment 1, and the above-described cable-stayed structure includes a cable-stayed rod 23, the upper and lower ends of the cable-stayed rod 23 are respectively welded with a second U-shaped mounting seat 231, the side wall of the vertical beam frame 24 is welded with a second lug seat 241 at the bottom of the trapezoidal beam frame part 211, and the second U-shaped mounting seat 231 and the second lug seat 241 are fixedly connected through a pin shaft connecting screw rod (for the same reason, after the pin shaft connecting screw rod penetrates the second lug seat 241 and the second U-shaped mounting seat 231, the two ends are fastened with mounting nuts).
[0051] By arranging the cable-stayed structure symmetrically in front and back on both sides of the bottom of each trapezoidal beam frame part 211, the trapezoidal beam frame part 211 and the vertical beam frame 24 are pulled and reinforced. Further increase the structural strength. After the pull and reinforcement, the overall steel structure is increased in the ability to prevent deviation and deformation.
[0052] The structural strength is increased by the cable-stayed structure and the pull and support structure in front and back and left and right directions of the entire steel frame, and the overall shape of the steel frame structure is greatly improved. The advantages are high deformation resistance, high resistance to strong wind damage, and high load bearing capacity.
[0053] Embodiment 3

The zigzag support frame 212 as a support structure greatly increases the structural compression resistance and deformation resistance.
[0055] The portal steel frame plant steel structure device also includes a connection beam 1 for fixedly installing a plurality of the portal steel beam units 2, the top of the upper top beam frame 21 is welded with a backing plate 26, and the backing plate 26 is fastened on the connection beam 1 through a plurality of fastening bolts.
