Description

Technical Field

[0001] The present invention relates to the technical field of railway construction, and particularly relates to a railway protection shed frame that is convenient to build. Background Art

[0002] During the construction of a railway bridge spanning a railway line in operation, due to the uncontrollability of the construction process, materials, tools, and waste often fall onto the operating line, resulting in railway accidents. Therefore, during the construction of a railway bridge project spanning a railway line, it is necessary to install a railway protection shed frame between the operating line and the main construction structure to protect the operating line from external construction conditions.

[0003] Chinese Patent with the authorization announcement number CN210067544U discloses a prefabricated and assembled steel structure protection shed frame for a railway operating line, which includes concrete foundation strips, embedded bolts, columns, crossbeams, tie rods, and roof panels; the lower parts of the embedded bolts are buried in the concrete foundation strips, and multiple groups of embedded bolts are arranged on the concrete foundation strips at intervals along the length direction of the concrete foundation strips; the lower end of each column is connected to the concrete foundation strip by a group of embedded bolts and nuts; both ends of each crossbeam are respectively connected to the upper ends of two corresponding columns; both ends of multiple tie rods are connected to adjacent crossbeams at intervals; the roof panels are laid on the outside of multiple crossbeams and tie rods and fixed with nuts.

[0004] The above-mentioned existing technical solutions have the following defects: Railway tracks are usually laid on the roadbed, and the height of the protection shed is usually higher than the sum of the heights of the roadbed and the train, and sometimes even reaches as high as 7 meters or 9 meters. At this time, the columns of the protection shed are required to be about 7 meters or 9 meters high. When the length of the columns is relatively long, the weight of the columns will be relatively heavy, which is not convenient for building the entire protection shed frame. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a railway protection shed frame that is convenient to build.

[0006] The above-mentioned invention purpose of the present invention is achieved through the following technical solutions:

[0007] A railway protection shed frame that is convenient to build includes concrete foundation strips that are parallel to each other and arranged at intervals. On both sides of the concrete foundation strips, a plurality of columns are arranged along the length direction of the concrete foundation strips. Between the ends of the plurality of columns on both sides that are far away from the concrete foundation strips, a plurality of longitudinal beams are arranged. Each column includes a plurality of spliced columns, and on the opposite surfaces of adjacent spliced columns, there are fixing parts for fixing adjacent spliced columns together.

[0008] By adopting the above technical solution, the upright columns are set as multiple spliced columns, and adjacent spliced columns can be detachably connected together through fixing parts, thus facilitating the transportation and erection of each upright column; the setting of multiple upright columns and multiple longitudinal beams improves the protection effect of the entire railway protection shed.

[0009] In a preferred example of the present invention, it can be further configured that: each of the spliced columns includes connecting plates that are parallel to each other and arranged at intervals, and pipe bodies are arranged at the four corners of the connecting rod between the two connecting plates of each spliced column. Both ends of each pipe body are fixedly arranged on the two side connecting plates, and a plurality of reinforcing rib plates are arranged between every two adjacent pipe bodies along the length direction of the pipe body. Both ends of each reinforcing rib plate are fixedly arranged on the adjacent pipe bodies.

[0010] By adopting the above technical solution, each spliced column includes connecting plates and four pipe bodies located between the connecting plates, which has high strength and can meet various different types of railway protection requirements, further improving the protection strength of the entire protection shed; the setting of the reinforcing rib plates can further increase the bearing capacity and strength of each spliced column, thereby further improving the protection strength of the entire protection shed.

[0011] In a preferred example of the present invention, it can be further configured that: the fixing part includes a plurality of U-shaped rods that simultaneously penetrate and are slidably connected to adjacent connecting plates. The plane where the U-shaped rods are located is perpendicular to the plane where the connecting plates are located, and the notch of the U-shaped rod faces the position where the concrete foundation strip is located.

[0012] By adopting the above technical solution, by setting the U-shaped rods and inserting the U-shaped rods into adjacent connecting plates at the same time, the installation and fixation of adjacent spliced columns can be completed. The fixing method for adjacent spliced columns is convenient and simple, improving the erection efficiency of the erectors when erecting the upright columns.

[0013] In a preferred example of the present invention, it can be further configured that: mutually cooperating connection grooves and connection strips are respectively arranged on the opposite faces of adjacent connecting plates, and both ends of the connection grooves penetrate through the connecting plates.

[0014] By adopting the above technical solution, the setting of the connection grooves and connection strips can play a guiding role for adjacent connecting plates, enabling adjacent connecting plates to better coincide, thereby facilitating the fixation of adjacent connecting plates with U-shaped rods.

[0015] In a preferred example of the present invention, it can be further configured that: the cross-section of the connection groove is set as a dovetail shape, and the connection strip is arranged in cooperation with the dovetail-shaped connection groove.

[0016] By adopting the above technical solution, the cross-section of the connecting groove is set to be dovetail-shaped, which can prevent the connecting bar from detaching from the connecting groove along the direction perpendicular to the length of the connecting groove. At this time, the detachment of two adjacent connecting plates along the vertical direction can be prevented, and the U-shaped rod can prevent the adjacent connecting plates from detaching from each other along the horizontal direction, further improving the fixing effect of fixing adjacent splicing columns together and facilitating the installation and fixing of adjacent splicing columns.

[0017] In a preferred example of the present invention, it can be further configured that: protrusions are provided on the surfaces of each topmost connecting plate facing away from the concrete foundation strip, and grooves for simultaneously inserting the protrusions on the connecting plates on both sides are provided along the length direction of the longitudinal beam on the surface of each longitudinal beam facing the concrete foundation strip.

[0018] By adopting the above technical solution, when it is necessary to fix the longitudinal beam to the columns on both sides, the longitudinal beam is driven to move the groove towards the protrusion on the connecting plate, so that the protrusion of the connecting plate is inserted into the groove on the longitudinal beam, thereby completing the installation and fixing of multiple longitudinal beams. Its installation method is convenient and simple, improving the construction efficiency of the construction personnel in building the protective shed frame.

[0019] In a preferred example of the present invention, it can be further configured that: bolts for passing through and being threadedly connected to the concrete foundation strip are provided on each bottommost connecting plate.

[0020] By adopting the above technical solution, the setting of the bolts facilitates fixing the lowermost splicing column to the concrete foundation strip, and drives the lowermost splicing column to have better firmness on the concrete foundation strip, and at the same time facilitates the installation and disassembly of the lowermost splicing column.

[0021] In a preferred example of the present invention, it can be further configured that: the railway protective shed frame that is convenient to build further includes a plurality of concrete foundation blocks located on both sides of the track. The distance between the opposite concrete foundation blocks on both sides is greater than the distance between the concrete foundation strips on both sides. Cable guys are provided between several of the columns and each concrete foundation block, and the distance between adjacent cable guys is equal. One end of the cable guy is provided with an anchor rod for fixing into the concrete foundation block, and the other end is provided with a shackle for fixing to one of the pipe bodies of the splicing column.

[0022] By adopting the above technical solution, the setting of the cable guys can support and fix the protective shed, preventing the protective shed frame from collapsing, thereby further improving the strength of the entire protective shed frame; the setting of the anchor rod can make one end of the cable guy have better firmness in the concrete foundation block, and the setting of the shackle can make the other end of the cable guy have better firmness on the pipe body, thereby improving the supporting effect of the cable guy on the entire protective shed frame and facilitating the fixing of the cable guy.

[0023] In a preferred embodiment, the present invention can be further configured as follows: a plurality of settlement joints are uniformly formed in the concrete foundation strip, and each settlement joint is filled with an asphalt wood board.

[0024] By adopting the above technical solution, the setting of the settlement joints can prevent the concrete foundation strip from being damaged due to uneven settlement of the foundation, thereby preventing the entire protective shed frame from collapsing. Using an asphalt wood board to fill the settlement joints can prevent water or other impurities from entering the settlement joints and affecting their use, and the filling of the asphalt wood board will not affect the use of the settlement joints either.

[0025] In a preferred embodiment, the present invention can be further configured as follows: a buffer layer is provided on the surface of each longitudinal beam facing away from the concrete foundation strip, and the buffer layer is used to buffer objects falling onto the longitudinal beam.

[0026] By adopting the above technical solution, the setting of the buffer layer can protect the longitudinal beam, facilitating its repeated use. And when an object on the bridge falls onto the longitudinal beam, it can buffer the object, preventing other objects from flying up and causing harm to people or objects around.

[0027] In summary, the present invention includes at least one of the following beneficial technical effects:

[0028] 1. The upright columns are set as multiple spliced columns, and each spliced column is set as a connecting plate and a plurality of pipe bodies connected between two connecting plates, which is convenient for transporting and building the upright columns. And the setting of the plurality of pipe bodies has higher strength, improving the protection effect of the protective shed frame;

Specific embodiments

[0039] The present invention will be further described in detail below with reference to the accompanying drawings.

[0040] Referring to Figure 1 , a railway protection shed frame which is convenient to build and disclosed by the present invention includes concrete foundation strips 1 which are arranged in parallel and at intervals; the concrete foundation strips 1 are poured at the positions where the protection shed frame needs to be installed by means of pouring.

[0041] As shown in Figure 1 , in order to prevent the concrete foundation strip 1 from being damaged due to uneven settlement of the foundation, a plurality of settlement joints 15 are uniformly formed in the concrete foundation strip 1, and each settlement joint 15 is filled with an asphalt wood board; in other embodiments, filling materials such as rubber strips can be used for filling.

[0042] Combining Figure 1 and Figure 2 , a plurality of columns 11 are arranged on both sides of the concrete foundation strip 1 along the length direction of the concrete foundation strip 1, and a plurality of longitudinal beams 12 are arranged at the ends of the plurality of columns 11 on both sides away from the concrete foundation strip 1.

[0043] In this embodiment, in order to improve the protection effect of the plurality of columns 11, in this embodiment, the distance between adjacent columns 11 is set to 10 cm, so that the plurality of columns 11 can be closely arranged with each other, thereby improving the protection effect of the plurality of columns 11.

[0044] Combining Figure 1 and Figure 2, in order to facilitate the entire column 11 to be applicable to railways of different heights and facilitate the transportation and erection of each column 11, each column 11 includes a plurality of spliced columns 111 spliced together.

[0045] Combined with Figure 1 and Figure 2 , in order to improve the protection effect of each spliced column 111, each spliced column 111 includes connecting plates 112 that are parallel to each other and arranged at intervals. Pipe bodies 113 are arranged at the four corners of the connecting rod between the two connecting plates 112 of each spliced column 111. Both ends of each pipe body 113 are fixedly arranged on the two side connecting plates 112. A plurality of reinforcing rib plates 114 are arranged between every two adjacent pipe bodies 113 along the length direction of the pipe body 113. Both ends of each reinforcing rib plate 114 are fixedly arranged on the adjacent pipe bodies 113.

[0046] Combined with Figure 2 and Figure 3 , in order to detachably connect adjacent spliced columns 111 together, so as to facilitate the erection of adjacent spliced columns 111, fixing parts for fixing adjacent spliced columns 111 together are arranged on the opposite surfaces of adjacent spliced columns 111.

[0047] Combined with Figure 2 and Figure 3 , the fixing part includes a plurality of U-shaped rods 115 that simultaneously pass through and are slidably connected to adjacent connecting plates 112. The plane where the U-shaped rods 115 are located is perpendicular to the plane where the connecting plates 112 are located. The notch of the U-shaped rod 115 faces the position where the concrete foundation strip 1 is located.

[0048] Combined with Figure 2 and Figure 3 , in order to further improve the fixing effect between adjacent connecting plates 112, mating connection grooves 116 and connection strips 117 are respectively arranged on the opposite surfaces of adjacent connecting plates 112. Both ends of the connection groove 116 penetrate through the connecting plate 112.

[0049] Combined with Figure 2 and Figure 3 , in order to prevent the connection strip 117 from disengaging from the connection groove 116 along the direction perpendicular to the length of the connection groove 116, in this embodiment, the cross-section of the connection groove 116 is set as a dovetail shape, and the connection strip 117 is arranged in cooperation with the dovetail-shaped connection groove 116; in other embodiments, the cross-section of the connection groove 116 can be set as an "Ω" shape, and the connection strip 117 is arranged in cooperation with the "Ω" shaped connection groove 116, which can also prevent the connection strip 117 from disengaging from the connection groove 116 along the direction perpendicular to the length of the connection groove 116.

[0050] When it is necessary to install and fix adjacent splicing columns 111, drive the adjacent splicing columns 111 to move the connecting plates 112 together. At this time, the connecting bar 117 can move into the connecting groove 116. The connecting bar 117 and the connecting groove 116 can prevent the adjacent connecting plates 112 from separating from each other in the vertical direction. After the connecting bar 117 moves into the connecting groove 116, insert the U-shaped rod 115 into the adjacent connecting plates 112 at the same time, so as to prevent the connecting bar 117 from separating from the connecting groove 116 and prevent the adjacent connecting plates 112 from separating from each other in the horizontal direction, improving the connection and fixing effect between the adjacent connecting plates 112 and facilitating the fixing of the adjacent splicing columns 111.

[0051] Combined with Figure 2 and Figure 4 , in order to facilitate the detachable connection of the bottommost splicing column 111 to the concrete foundation strip 1, bolts 13 for passing through and threadedly connecting into the concrete foundation strip 1 are provided on each bottommost connecting plate 112; in this embodiment, the bolts 13 are expansion bolts.

[0052] In other embodiments, a slot can be opened on the concrete foundation strip 1 and at the position where each connecting plate 112 is located, and a plug block inserted into the slot is provided on the connecting plate 112, and the fixing between the bottommost splicing column 111 and the concrete foundation strip 1 can also be completed, and its fixing method is more convenient.

[0053] Combined with Figure 1 and Figure 5 , in order to detachably connect multiple longitudinal beams 12 to the two side columns 11, protrusions 122 are provided on the surfaces of each topmost connecting plate 112 facing away from the concrete foundation strip 1, and grooves 121 for simultaneously inserting the protrusions 122 on the two side connecting plates 112 are opened along the length direction of the longitudinal beam 12 on the surface of each longitudinal beam 12 facing the concrete foundation strip 1; in this embodiment, the protrusions 122 are fixed to the connecting plates 112 by welding.

[0054] In other embodiments, the topmost connecting plate 112 and the longitudinal beam 12 can be fixed by high-strength bolts and nuts, and the fixing between the topmost multiple splicing columns 111 and the longitudinal beam 12 can also be completed; at the same time, two steel bars can be welded at both ends of the groove 121, and the arrangement of the steel bars can block the protrusions 122 into the groove 121, thereby further improving the installation effect of the longitudinal beam 12 installed on multiple connecting plates 112.

[0055] Combined with Figure 1 and Figure 5, in order to further improve the protection effect of multiple longitudinal beams 12, a buffer layer 16 is provided on the surface of each longitudinal beam 12 facing away from the concrete foundation strip 1. The buffer layer 16 is used to buffer the objects falling onto the longitudinal beam 12. In this embodiment, the buffer layer 16 is set as an insulating foam layer. In other embodiments, the buffer layer 16 can be set as other materials such as thick wooden boards or rubber.

[0056] Combined with Figure 1 and Figure 5 , in order to further improve the stability of the entire protective shed frame, the railway protective shed frame that is easy to build further includes a plurality of concrete foundation blocks 14 located on both sides of the track. The concrete foundation blocks 14 are poured at the positions where they need to be installed by pouring.

[0057] Combined with Figure 1 and Figure 5 , the distance between the two relatively concrete foundation blocks 14 on both sides is greater than the distance between the two concrete foundation strips 1 on both sides. Cable guys 141 are provided between several columns 11 and each concrete foundation block 14, and the distances between adjacent cable guys 141 are equal.

[0058] Combined with Figure 1 and Figure 5 , in this embodiment, in order to improve the pulling and supporting effect of the cable guys 141 on the entire shed frame, the connection points of the cable guys 141 on both sides of the protective shed frame on the shed frame are not less than two-thirds of the height of the shed frame, and the angle between the cable guys 141 and the shed frame is greater than 45 degrees. One cable guy 141 is set every 3 meters along the extension direction of the railway.

[0059] Combined with Figure 5 and Figure 6 , in order to fix the two ends of the cable guy 141 to the shed frame and the concrete foundation block 14 respectively, an anchor rod (not shown in the figure) for fixing into the concrete foundation block 14 is provided at one end of the cable guy 141, and a shackle 143 for fixing to one of the pipe bodies 113 of the splicing column 111 is provided at the other end. In this embodiment, the anchor rod 142 is set as a threaded steel bar anchor rod.

[0060] In this embodiment, both the anchor rod and the shackle 143 are prior arts known to those skilled in the art, and the specific structures of the anchor rod and the shackle 143 will not be described in detail.

[0061] The implementation principle of this embodiment is as follows: When it is necessary to build a protective shed frame, first pour the concrete foundation strip 1 and the concrete integrated block. After the pouring of the concrete foundation strip 1 and the concrete foundation block 14 is completed, install the lowermost splicing column 111 onto the concrete foundation strip 1 through bolts 13. At this time, splice and fix the next splicing column 111, and slide the connecting strip 117 on the connecting plate 112 driven by the splicing column 111 into the connecting groove 116 on the adjacent connecting plate 112. At this time, simultaneously pass the U-shaped rod 115 through the adjacent connecting plates 112 to complete the fixation between the adjacent splicing columns 111. Drive the longitudinal beam 12 to move the groove 121 towards the protrusion 122, so that the connecting plate 112 drives the protrusion 122 to be inserted into the groove 121 on the longitudinal beam 12, thereby completing the installation and fixation of multiple longitudinal beams 12. When the installation of the longitudinal beam 12 is completed, lay a buffer layer 16 on each longitudinal beam 12. When pouring the concrete foundation block 14, the anchor rod 142 at one end of the guy wire 141 can be first poured into the concrete foundation block 14. At this time, fix the other end of the guy wire 141 to one of the pipe bodies 113 of the splicing column 111 through a shackle 143 to complete the construction of the entire protective shed frame. The use of multiple splicing columns 111 facilitates the transportation and construction of each column 11 when the height of the entire protective shed frame is relatively high, improving the construction efficiency of the construction personnel.

[0062] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
