Abstract
Description
Technical Field
[0001] This utility model relates to the renovation of steel structure workshops, and in particular to a canopy span connection structure for steel structure workshops. Background Technology
[0002] With the optimization and upgrading of my country's industrial structure, more and more old factory buildings need to undergo functional transformation, renovation, or expansion. During these renovations or expansions, adjustments to the building's floor height, span, and passageway layout may be necessary. Currently, the most common factory renovation involves adding roofs to the open spans between factory buildings or constructing additional spans on the existing foundation. This results in an excessively long overall length of the new factory building, leading to problems such as high temperature stress or discrepancies in seismic resistance between the two buildings due to different structural types. Furthermore, the structural stability at the connection points of the added spans is often poor. Summary of the Invention
[0003] In view of this, the present invention proposes a canopy span connection structure for steel structure factory buildings.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: The present invention discloses a canopy span connection structure for steel structure workshops, wherein the canopy span connection structure is disposed between a first workshop and a second workshop, and includes a first connecting component, a second connecting component, a first limiting component, and a second limiting component. The first connecting component includes a first upper bracket and a first lower bracket spaced apart from a first steel column. A first sliding support is installed on the first lower bracket via the first limiting component, which causes the first sliding support to undergo lateral displacement under force. The second connecting component includes a second bracket disposed on a second steel column. A second sliding support is connected to the second bracket via the second limiting component, which causes the second sliding support to undergo lateral displacement under force. One end of the canopy span beam is fixedly connected to the second sliding support, and the other end is movably mounted on the first sliding support. The canopy span beam is connected to the first upper bracket via at least two long screws. The beneficial effects are: This utility model fixes one end of the span beam to one of the sliding supports, and movably places the other end on another sliding support and suspends it. When wind load or large vibration occurs, the two sliding supports can slide laterally to release energy. The suspended installation of one end of the span beam can pull the beam and prevent it from falling off the sliding support, which not only improves safety, but also facilitates later maintenance.
[0005] Preferably, the first limiting component and the second limiting component have the same structure. The first limiting component includes a pair of lower limiting plates spaced apart on the first lower bracket and an upper limiting plate disposed on each of the lower limiting plates. The distance between the two upper limiting plates is smaller than the distance between the two lower limiting plates. The first sliding support is inserted between the two lower limiting plates, and the two upper limiting plates vertically limit the first sliding support. The beneficial effect is that the pair of lower limiting plates of this invention can limit the sliding support in the front-rear direction, and the upper and lower limiting plates can vertically limit the sliding support, thus improving safety.
[0006] Compared with the prior art, the advantages of this utility model are as follows: This utility model fixes one end of the span beam to one of the sliding supports, and movably places the other end on another sliding support and suspends it. When wind load or large vibration occurs, the two sliding supports can slide laterally to release energy and improve seismic performance. In addition, since one end of the span beam is suspended, when the deformation is large, the beam can be pulled to a certain extent to prevent it from falling off the sliding support, thus improving safety and facilitating later maintenance.

[0011] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. These embodiments are implemented based on the technical solution of the present invention, and detailed implementation methods and specific operation processes are given. However, the scope of protection of the present invention is not limited to the following embodiments.
[0012] It should be noted that in the description of this invention, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
[0013] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0014] like Figure 1-4 As shown, this invention proposes a canopy-span connection structure between steel structure workshops, located between a first workshop and a second workshop. It includes a first connecting component, a second connecting component, a first limiting component, and a second limiting component. The first connecting component includes a first upper bracket 2 and a first lower bracket 3 spaced apart from a first steel column 1 (the first steel column 1 is a structural column of the first workshop). A first sliding support 4 is installed on the first lower bracket 3 via the first limiting component, and the limiting effect of the first limiting component ensures that the first sliding support 4 can only move laterally under force. The second connecting component includes a canopy-span connection structure located between a second steel column 5 (the second steel column 6) and a second steel column 7 (the second steel column 8). The second corbel 6 on column 5 (the structural column of the second factory building) is connected to the second sliding support via the second limiting component. The limiting effect of the second limiting component ensures that the second sliding support can only be displaced laterally under force. One end of the span beam 8 (the supporting beam of the span between the two factory buildings) is fixed to the second sliding support, and the other end is movably mounted on the first sliding support 4. The span beam 8 is connected to the first upper corbel 2 via at least two long screws 7 (which can be threaded steel bars). The lower part of the long screw 7 is welded to the span beam 8, and the upper part extends out of the first upper corbel 2 and is welded to the first upper corbel 2. This utility model fixes one end of the canopy span beam 8 between the first and second workshops to one of the sliding supports, and movably places the other end of the canopy span beam 8 on another sliding support and suspends it. When wind load or large vibration occurs, the two sliding supports can slide laterally to release energy and improve seismic performance. In addition, since one end of the canopy span steel beam is suspended, when the deformation is large, the steel beam can be pulled to a certain extent to prevent the steel beam from falling off the sliding support and improve safety.
[0015] The first and second limiting components have the same structure. A detailed explanation will be provided using the first limiting component on the first lower bracket 3 as an example. (Combined with...) Figure 2-4It is understood that the first limiting component includes a pair of lower limiting plates 9 spaced apart on the first lower bracket 3 and an upper limiting plate 10 disposed on each lower limiting plate 9. The distance between the two upper limiting plates 10 is less than the distance between the two lower limiting plates 9. The first sliding support 4 is inserted between the two lower limiting plates 9, and the two upper limiting plates 10 extend above the first sliding support 4, limiting the vertical movement of the first sliding support 4. The upper limiting plate 10 and the lower limiting plate 9 are arranged in pairs, and the lower limiting plate 9 is welded to the upper limiting plate 10. In actual construction, the upper limiting plate 10 and the lower limiting plate 9 are preferably made of thick steel plates. The upper limiting plate 10 and the lower limiting plate 9 are pre-welded together, and the lower limiting plate 9 is welded to the first lower bracket 3 after the first sliding support 4 is hoisted into place, limiting the movement of the first sliding support 4. The limiting effect of the first limiting component ensures that the first sliding support 4 can only move along the length of the bracket.
[0016] The construction process of this utility model is as follows: (Combined with...) Figure 1 It is understood that a first sliding support 4 is installed on the first lower bracket 3, and a second sliding support is installed on the second bracket 6. The right end of the span beam 8 is fixedly installed on the second sliding support, and the left end of the span beam 8 is placed on the first sliding support 4. The first limiting component is welded to the first lower bracket 3, and the second limiting component is welded to the second bracket 6. Two long screws are used to connect the span reinforcement and the first upper bracket 2 together, completing the construction of the span beam 8. This process is repeated to complete the installation of multiple span beams 8 between the first and second workshops.
[0017] Finally, it should be emphasized that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
