Description

Technical Field

[0001] This utility model relates to the field of steel structure corridor technology, specifically to a multi-story steel structure corridor. Background Technology

[0002] With the continuous development of the construction industry, many projects use connecting structures to link building complexes, forming interconnected buildings. These connecting structures are generally called corridors, which facilitate the connection between two buildings. At the same time, corridors have good lighting effects and a wide view.

[0003] Chinese utility model patent application number 202221047103.X discloses a multi-layer steel corridor structure, comprising multiple standard structural layers and multiple steel corridors, which are alternately arranged vertically and sequentially fixedly connected to each other. Each standard structural layer includes multiple horizontal steel beams, and each steel corridor includes multiple horizontal chords. Several floor deckings are installed at the horizontal steel beams and horizontal chords, and these floor deckings are laid on the horizontal steel beams or horizontal chords to form corridor passageways. When installed between the floors of two towers, this patent can provide multiple passageways for the two tower floors, facilitating passage between twin-tower high-rise buildings. However, this patent has the following drawback: the strength of the corridor support structure is not high, making it difficult to meet the requirements of high-volume traffic or heavy loads. Summary of the Invention

[0005] The purpose of this utility model is achieved through the following technical solution: a multi-layer steel structure corridor, comprising two rows of parallel and opposite first support columns and multiple standard structural layers fixed between the two rows of first support columns and arranged sequentially from top to bottom. Each standard structural layer has a cantilever platform fixed outward on the front side of the middle part, and second support columns are vertically fixed on the left and right sides of the front side of the cantilever platform. Each standard structural layer includes a unit truss fixed between the two rows of first support columns and multiple first support plates fixed to the top of the unit truss.

[0006] Furthermore, each unit truss includes multiple first longitudinal beams fixed longitudinally between each pair of opposite first support columns, multiple first transverse beams fixed transversely between each row of two adjacent first support columns, and multiple first reinforcing beams fixed longitudinally between the middle of two opposite first transverse beams. Each first reinforcing beam is fixed with a grid-shaped space frame between it and the adjacent first longitudinal beam. The front and rear sides of the grid-shaped space frame are respectively fixedly connected to the two opposite first transverse beams.

[0007] Furthermore, each of the cantilever trusses includes a second crossbeam fixed between two second support columns, a second longitudinal beam fixed between each second support column and a corresponding first support column, and a second reinforcing beam fixed between the second crossbeam and the middle of the corresponding first crossbeam.

[0008] Furthermore, each of the first support columns includes an anchor column fixed to the ground and a standard column fixed to the top of the anchor column. The bottom of the anchor column is fixed with a base plate, and multiple anchor holes are evenly opened vertically on the top of the base plate. Multiple reinforcing blocks are evenly fixed on the outer side wall of the bottom of the anchor column. The bottom of each reinforcing block is fixedly connected to the top of the base plate.

A first fixing hole is opened at the bottom of each first fixing plate corresponding to the position of each first connecting hole, and a second fixing hole is opened at the top of each first fixing plate corresponding to the position of each second connecting hole.

[0010] Furthermore, each of the first support columns is fixed with a connecting structure corresponding to the position of each of the first crossbeams and first longitudinal beams. The left and right ends of each first crossbeam are fixedly connected to the two adjacent first support columns in the horizontal direction through the corresponding connecting structure. The front and rear ends of each first longitudinal beam are fixedly connected to the two opposing first support columns in the vertical direction through the corresponding connecting structure. The connecting structure includes two first limiting plates and a second limiting plate that are fixed horizontally parallel to one side of the first support column, and a third connecting plate that is fixed vertically between the first limiting plate and the second limiting plate. The front end of the third connecting plate has multiple third connecting holes in the horizontal direction.

[0011] Furthermore, each of the first crossbeams has multiple third fixing holes at both ends. The top of the first crossbeam abuts against the bottom of the first limiting plate, and the bottom of the first crossbeam abuts against the top of the second limiting plate. Both ends of the first crossbeam are screwed and fixed between two horizontally adjacent first support columns by multiple third bolts passing through the third fixing holes and the corresponding third connecting holes in sequence.

Detailed Implementation

[0024] To facilitate understanding by those skilled in the art, the following description is provided in conjunction with embodiments and appendices. Figure 1-8 The present invention will be further described below. The content mentioned in the embodiments is not intended to limit the present invention.

[0025] See Figure 1-8 A multi-story steel structure corridor includes two rows of parallel and opposite first support columns 1 and multiple standard structural layers 2 fixed between the two rows of first support columns 1 and arranged sequentially from top to bottom. Each standard structural layer 2 has a cantilever platform 3 fixed outward on the front side of its middle section. The left and right sides of the front side of the cantilever platform 3 are vertically fixed with second support columns 4. Each standard structural layer 2 includes a unit truss 21 fixed between the two rows of first support columns 1 and multiple first support plates 22 fixed to the top of the unit truss 21. Each cantilever platform 3 includes a cantilever platform truss 31 and a second support plate 32 fixed to the top of the cantilever platform truss 31.

[0026] The multi-layer steel structure connecting corridor of this utility model adopts a modular and standardized design, consisting of multiple standard structural layers 2, cantilevered platforms 3, first support columns 1 and second support columns 4. By setting the first support columns 1 and second support columns 4, the load-bearing capacity of the corridor bridge is significantly improved. The unit truss 21 is prefabricated in the factory, which can effectively reduce on-site processing work, not only improving the precision and quality consistency of components, but also greatly shortening the on-site construction cycle. In addition, the cantilevered platforms 3 can alleviate the pedestrian flow pressure of the connecting corridor.

[0027] In this embodiment, each unit truss 21 includes multiple first longitudinal beams 23 longitudinally fixed between each pair of opposite first support columns 1, multiple first transverse beams 24 transversely fixed between each row of adjacent first support columns 1, and multiple first reinforcing beams 25 longitudinally fixed between the middle of two opposite first transverse beams 24. A grid-shaped space frame 26 is fixed between each first reinforcing beam 25 and its adjacent first longitudinal beam 23. The front and rear sides of the grid-shaped space frame 26 are respectively fixedly connected to two opposite first transverse beams 24. Specifically, the grid-shaped space frame 26 is formed by welding multiple steel beams together. The grid-shaped space frame 26 can evenly transfer the load to the surrounding first transverse beams 24, first longitudinal beams 23, and first reinforcing beams 25, thus preventing excessive local stress on the covered bridge and potential damage to the bridge structure. The first horizontal beam 24, the first vertical beam 23, and the first reinforcing beam 25 serve as the main skeleton of the unit truss 21 and are fixedly connected to the first support column 1 to form multiple rectangular foundation frames. Each rectangular foundation frame has a grid-shaped space frame 26 fixed inside, forming a grid-structured unit truss 21. The grid-structured unit truss 21 can improve the load-bearing capacity of the covered bridge.

[0028] In this embodiment, each cantilever truss 31 includes a second crossbeam 33 fixed between two second support columns 4, a second longitudinal beam 34 fixed between each second support column 4 and a corresponding first support column 1, and a second reinforcing beam 35 fixed between the second crossbeam 33 and the middle of the corresponding first crossbeam 24. Specifically, the second crossbeam 33, the second longitudinal beam 34, the second reinforcing beam 35, the first support column 1, and the second support column 4 are fixed together with bolts. The cantilever truss 31 can transfer the load borne by the surface of the cantilever 3 to the first support column 1 and the second support column 4, thus maintaining the stability of the cantilever 3 structure.

[0029] In this embodiment, each of the first support columns 1 includes an anchor column 11 fixed to the ground and a standard column 12 fixed to the top of the anchor column 11. A base plate 111 is fixed to the bottom of the anchor column 11. A plurality of anchor holes 112 are vertically and evenly provided on the top of the base plate 111. A plurality of reinforcing blocks 113 are evenly fixed to the outer side wall of the bottom of the anchor column 11. The bottom of each reinforcing block 113 is fixedly connected to the top of the base plate 111. An anchoring steel bar 114 is fixed in the middle of the bottom of the base plate 111. The first support column 1 forms a structure of lower anchoring and upper load-bearing through the anchor column 11 and the standard column 12. The anchor column 11 can increase the load-bearing area through the base plate 111, which can avoid excessive local stress on the ground and settlement, thus affecting the stability of the connecting corridor. The structure of reinforcing blocks 113, anchor holes 112 and anchoring steel bars 114 can enhance the anti-tilting performance of the first support column 1 and the second support column 4. Similarly, the structure of the second support column 4 is the same as that of the first support column 1, and will not be described again here.

[0030] In this embodiment, multiple first connecting plates 13 are vertically fixed to the top outer wall of the anchoring column 11, and a second connecting plate 14 is vertically fixed to the bottom outer wall of the standard column 12 corresponding to the position of each first connecting plate 13. Each first connecting plate 13 has multiple first connecting holes 15 horizontally, and each second connecting plate 14 has multiple second connecting holes 16 horizontally. A first fixing plate 5 is fixed to the left and right sides of each first connecting plate 13 and the corresponding second connecting plate 14. A first fixing hole 51 is opened at the bottom of each first fixing plate 5 corresponding to the position of each first connecting hole 15, and a second fixing hole 52 is opened at the top of each first fixing plate 5 corresponding to the position of each second connecting hole 16. The anchor column 11 and the standard column 12 are fixed by multiple first bolts passing sequentially through the first fixing hole 51 of one of the first fixing plates 5, the corresponding first connecting hole 15 of the first connecting plate 13, and the first fixing hole 51 of the other first fixing plate 5. They are also fixed by multiple second bolts passing sequentially through the second fixing hole 52 of one of the first fixing plates, the corresponding second connecting hole 16 of the second connecting plate 14, and the second fixing hole 52 of the other first fixing plate 5. The first support column 1 adopts a split design. The bottoms of the two first fixing plates 5 clamp the first connecting plate 13, and the tops of the two first fixing plates 5 clamp the second connecting plate 14. The anchor column 11 and the standard column 12 are assembled by multiple bolts, avoiding the integral casting of the first support column 1 and the second support column 4. This also reduces the size and load-bearing requirements of the transport vehicle, facilitating transportation.

[0031] In this embodiment, each of the first support columns 1 is fixed with a connecting structure 6 at the position corresponding to each of the first horizontal beams 24 and the first vertical beams 23. The left and right ends of each first horizontal beam 24 are fixedly connected to two horizontally adjacent first support columns 1 through the corresponding connecting structure 6. The front and rear ends of each first vertical beam 23 are fixedly connected to two vertically opposite first support columns 1 through the corresponding connecting structure 6. The connecting structure 6 includes two horizontally parallel first limiting plates 61 and second limiting plates 62 fixed to one side of the first support column 1, and a third connecting plate 63 vertically fixed between the first limiting plate 61 and the second limiting plate 62. The front end of the third connecting plate 63 has multiple horizontally opened third connecting holes 64. By setting the connecting structure 6, a stable connection point can be provided for the first support column 1. Similarly, each of the second support columns 4 has a connecting structure 6 fixed at both ends of the second crossbeam 33 and each of the second longitudinal beams 34. The left and right ends of the second crossbeam 33 are fixedly connected to the two second support columns through the corresponding connecting structure 6. The front and rear ends of each second longitudinal beam 34 are fixed to each second support column 4 and the corresponding first support column 1 through the corresponding connecting structure 6. This will not be described in detail here.

[0032] In this embodiment, each of the first crossbeams 24 has multiple third fixing holes 241 at both its left and right ends. The top of the first crossbeam 24 abuts against the bottom of the first limiting plate 61, and the bottom of the first crossbeam 24 abuts against the top of the second limiting plate 62. Both ends of the first crossbeam 24 are screwed and fixed between two laterally adjacent first support columns 1 by multiple third bolts passing through the third fixing holes 241 and the corresponding third connecting holes 64 in sequence. The above structure is used to fix the first crossbeam 24 between two laterally adjacent first support columns 1. Similarly, the installation method of the second crossbeam 33 is the same as that of the first crossbeam 24, and will not be described again here.

[0033] In this embodiment, each of the first longitudinal beams 23 has multiple fourth fixing holes 231 at both its front and rear ends. The top of the first longitudinal beam 23 abuts against the bottom of the first limiting plate 61, and the bottom of the first longitudinal beam 23 abuts against the top of the second limiting plate 62. The front and rear ends of the first longitudinal beam 23 are screwed and fixed between two longitudinally adjacent first support columns 1 by multiple fourth bolts passing through the fourth fixing holes 231 and the corresponding third connecting holes 64. The above structure is used to fix the first longitudinal beam 23 between two longitudinally opposite first support columns 1. Similarly, the installation method of the second longitudinal beam 34 is the same as that of the first longitudinal beam 23, and will not be described again here.

[0034] In this embodiment, a second fixing plate 242 is fixed to the middle of one side of each pair of first crossbeams 24. The front end of the second fixing plate 242 has multiple fifth fixing holes 243. Both ends of the first reinforcing beam 25 have multiple fourth connecting holes 251. The front and rear ends of the first reinforcing beam 25 are screwed and fixed between the middle of the two opposing first crossbeams 24 by multiple fifth bolts that pass sequentially through the fifth fixing holes 243 and the corresponding fourth connecting holes 251. This structure allows the first reinforcing beam 25 to be fixed between the two opposing first crossbeams 24. Similarly, the installation method of the second reinforcing beam 35 is the same as that of the first reinforcing beam 25, and will not be described again here.

[0035] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
