[0047] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0048] See Figure 1 - Figure 12 As shown, an embodiment of the present invention provides an efficient and quick-assembly pedestrian bridge, including a cross beam 100, longitudinal beams 200, a bridge deck 300, and a fixing strip 400; a transverse and longitudinal beam connecting plate 201 for connecting with the cross beam 100 is fixedly arranged on the longitudinal beam 200, and the transverse and longitudinal beam connecting plate 201 is connected with the cross beam 100 through threaded parts; the fixing strip 400 presses the bridge deck 300 on the cross beam 100 and the longitudinal beams 200, plug sockets are arranged on both sides of the longitudinal beam 200, and plug connectors 410 adapted to the plug sockets are arranged on the fixing strip 400.

[0049] Specifically, during splicing, the staff hoists a plurality of longitudinal beams 200 to a preset position on the bridge platform, and then lays the bridge deck 300 on the longitudinal beams 200 through the fixing strip 400. As the bridge deck 300 is laid, when it is laid to the preset position where the cross beam 100 needs to be installed, the cross beam 100 is inserted between two adjacent longitudinal beams 200, and the cross beam 100 is made to correspond to the transverse and longitudinal beam connecting plate 201 on the longitudinal beam 200. The staff connects the longitudinal beam 200 and the cross beam 100 together through threaded parts; the plug connectors 410 on the fixing strip 400 can be inserted into the plug sockets on the side of the longitudinal beam 200. After the fixing strip 400 is inserted into the plug sockets, the fixing strip 400 can press the bridge deck 300 tightly on the cross beam 100 and the longitudinal beams 200; through such a setting, it enables the staff to conveniently and quickly complete the assembly of the pedestrian bridge and improve the construction speed.

[0050] Specifically, after the plug-in member 410 on the fixing bar 400 is inserted into the socket of the longitudinal beam 200, the top plate of the longitudinal beam 200 will limit the plug-in member 410, so that the plug-in member 410 cannot be lifted upward, so that the fixing bar 400 can press the bridge deck 300 on the longitudinal beam 200 and the cross beam 100.

[0051] Among them, when installing the fixing bar 400, the staff first place the fixing bar 400 on the longitudinal beam 200, and the fixing bar 400 is perpendicular to the longitudinal beam 200. Then the staff move the fixing bar 400 close to the bridge deck 300 and press the fixing bar 400 against the bridge deck 300. Finally, the staff push the fixing bar 400 in the direction of the cross beam 100, so that the plug-in member 410 on the fixing bar 400 can be inserted into the socket on the longitudinal beam 200, thus completing the fixation of the fixing bar 400.

[0052] Among them, the cross beam 100 and the longitudinal beam 200 are connected together by threaded parts. The production of the cross beam 100 and the longitudinal beam 200 can be carried out in the factory, and then the cross beam 100 and the longitudinal beam 200 can be spliced by threaded parts at the construction site without welding at the construction site, greatly improving the construction speed.

[0053] It should be noted that fixing bars 400 are provided on both sides of each row of bridge decks 300 to fix the bridge decks 300 through the fixing bars 400.

[0054] It should be noted that the threaded parts can be bolts, and those skilled in the art can also make selections according to actual needs.

[0055] It should also be noted that the numbers of the cross beam 100, the longitudinal beam 200, the bridge deck 300 and the fixing bar 400 are all multiple.

[0056] See Figure 1 and Figure 2 As shown in

[0057] Specifically, the cross beam 100 is made of T-shaped steel, and the longitudinal beam 200 can be made of I-shaped steel, so as to improve the load-bearing capacity of the pedestrian bridge.

[0058] See Figure 1 and Figure 2 As shown in

[0059] Specifically, reinforcing ribs 210 are provided on both sides of the longitudinal beam 200. By providing the reinforcing ribs 210, the stability of the longitudinal beam 200 is improved, and the connection between the reinforcing ribs 210 and the top plate of the longitudinal beam 200 can form a socket. When splicing the fixing strip 400, the plug-in member 410 on the fixing strip 400 can be inserted onto the reinforcing rib 210, and the top plate of the longitudinal beam 200 will impose a constraint on the plug-in member 410, making it impossible for the fixing strip 400 to be pulled up in the vertical direction, thereby ensuring that the bridge deck 300 pressed by the fixing strip 400 can be stably laid on the cross beam 100 and the longitudinal beam 200.

[0060] Among them, those skilled in the art can select the quantity and type of the reinforcing ribs 210 according to actual needs, and details will not be elaborated herein.

[0061] See Figure 1 、 Figure 6 、 Figure 9 and Figure 10 As shown in

[0062] Specifically, the cross-section of the fixing strip 400 is set in a T shape, so that the fixing strip 400 can fix the bridge decks 300 on both sides.

[0063] See Figure 10 As shown in

[0064] Specifically, the plug-in member 410 is set as a spline tooth, and when the fixing strip 400 is assembled, the spline tooth can be inserted onto the reinforcing rib 210.

[0065] See Figure 8 As shown in

[0066] Specifically, the bridge deck 300 is set in a "convex" shape, and the fixing strip 400 can be embedded between two adjacent bridge decks 300.

[0067] Among them, when the fixing strip 400 is arranged on two bridge decks 300, the fixing strip 400 can be embedded between the two bridge decks 300, and the top plate of the fixing strip 400 can be adapted to the recess of the bridge deck 300, so that the fixing strip 400 can fix the bridge deck 300, and through the restriction of the fixing strip 400, the bridge deck 300 can be prevented from swaying randomly.

[0068] See Figure 1 、 Figure 11And Figure 12 As shown, in an alternative solution of this embodiment, the high-efficiency and quick-assembly pedestrian bridge further includes a card seat 500. The card seat 500 is inserted on the reinforcing ribs 210 on the two outermost longitudinal beams 200. A slot portion 510 for inserting into the reinforcing ribs 210 is provided on the card seat 500, and the slot portion 510 is connected to the reinforcing ribs 210 through threaded members. A socket portion 520 is further provided on the card seat 500, and both ends of the bridge deck 300 and the fixing strip 400 can be inserted into the socket portion 520.

[0069] Specifically, after the cross beam 100 and the longitudinal beam 200 are spliced, the bridge deck 300 is laid. After the bridge deck 300 is laid, the card seat 500 is assembled on the longitudinal beam 200. The slot portion 510 on the card seat 500 can be inserted on the reinforcing ribs 210 outside the longitudinal beam 200, and the staff strengthens the connection between the slot portion 510 and the reinforcing ribs 210 through bolts. When installing the card seat 500, the socket portion 520 of the card seat 500 is made to correspond to both the fixing strip 400 and the bridge deck 300. After the insertion portion of the card seat 500 is connected to the reinforcing ribs 210 of the longitudinal beam 200, both ends of the fixing strip 400 and the bridge deck 300 can be inserted into the socket portion 520 of the card seat 500, thereby restricting the ends of the fixing strip 400 and the bridge deck 300 and preventing the fixing strip 400 and the bridge deck 300 from sliding randomly.

[0070] Among them, two fixing strips 400 can be provided on both sides of each row of bridge decks 300. The two fixing strips 400 are respectively inserted into the longitudinal beam 200 from both ends of each row of bridge decks 300 inward, and then a card seat 500 is provided on the outermost longitudinal beam 200 to restrict the fixing strip 400 through the card seat 500, so that the fixing strip 400 can be inserted into the socket of the longitudinal beam 200, preventing the fixing strip 400 from loosening, and thus ensuring the stability of the bridge deck 300.

[0071] See Figure 1 As shown, in an alternative solution of this embodiment, the high-efficiency and quick-assembly pedestrian bridge further includes a guardrail 600. An installation groove 530 for installing the guardrail 600 is further provided on the card seat 500.

[0072] Specifically, the card seat 500 further includes an installation groove 530. After the card seat 500 is fixed on the longitudinal beam 200, the staff can insert the guardrail 600 into the installation groove 530.

[0073] Among them, the staff can strengthen the connection between the installation groove 530 and the guardrail 600 through bolts to improve the stability of the guardrail 600.

[0074] Among them, through holes are provided on both the installation groove 530 and the guardrail 600. After the guardrail 600 is inserted into the installation groove 530, the through holes on the installation groove 530 and the guardrail 600 are aligned, and then the staff inserts bolts to reinforce both the installation groove 530 and the guardrail 600.

[0075] See Figure 1 、 Figure 2 and Figure 3 As shown in

[0076] Specifically, when the length of the longitudinal beam 200 of the high-efficiency and quick-assembly pedestrian bridge provided in this embodiment is relatively large, multiple longitudinal beams 200 can be connected together. Longitudinal beam connection plates 202 are provided at one end or both ends of the longitudinal beam 200. Adjacent longitudinal beams 200 can be connected together through the longitudinal beam connection plates 202, and the longitudinal beam connection plates 202 of the two longitudinal beams 200 can be connected together by bolts.

[0077] See Figure 1 、 Figure 2 and Figure 5 As shown in

[0078] Specifically, an oblong hole 203 for connecting to the abutment is provided at the bottom of the longitudinal beam 200. Through the oblong hole 203, the longitudinal beam 200 can be connected to the bolts embedded in the abutment.

[0079] Among them, the connection hole for connecting the longitudinal beam 200 to the bolts embedded in the abutment is set as an oblong hole 203. After the connection is completed, it can ensure that during the long-term use of the longitudinal beam 200, when it expands and contracts due to temperature changes in the weather, the longitudinal beam 200 can still be connected to the bolts embedded in the abutment, without damaging the bolts or the longitudinal beam 200.

[0080] In summary, the cross beams 100 and longitudinal beams 200 in the high-efficiency and quick-assembly pedestrian bridge provided in this embodiment are processed in sections in the factory, which is convenient for transportation.

[0081] Moreover, the bridge deck 300 in the high-efficiency and quick-assembly pedestrian bridge provided in this embodiment uses a GFRP (glass fiber reinforced polymer) bridge deck. The GFRP bridge deck has high strength, low self-weight, and good durability, and the normal service life is not less than 50 years. It can be carried by manual labor during construction.

[0082] In addition, through the provision of the fixing strip 400 and the clamping seat 500, the efficient and quickly assembled pedestrian bridge provided in this embodiment can effectively combine the bridge deck 300 with the steel beam to share the force together, and a mounting groove 530 for installing the guardrail 600 is reserved on the clamping seat 500.

[0083] Moreover, the efficient and quickly assembled pedestrian bridge provided in this embodiment does not require welding during on-site construction. It is entirely bolt-connected and can be quickly assembled into shape, improving the construction speed.

[0084] The efficient and quickly assembled pedestrian bridge provided in this embodiment has a simple structure and is convenient for transportation. All components are produced in a factory and assembled on-site. There is no need to set up any construction scaffolds. It is directly installed on the bridge deck. Changing welding to bolting greatly reduces the construction difficulty, shortens the construction period, and reduces the construction cost.

[0085] The splicing process of the efficient and quickly assembled pedestrian bridge provided in this embodiment is as follows: The staff arranges multiple segments of the connected single-piece longitudinal beam 200 in sequence on the ground, assembles the longitudinal beam 200 into a whole through the longitudinal beam connecting plate 202, hoists the assembled single-piece longitudinal beam to the pre-marked design installation position on the bridge abutment by a crane, and connects the longitudinal beam 200 with the bridge abutment with bolts at the long circular holes 203 of the longitudinal beam 200; then lay a row of bridge decks 300, install the fixing strip 400 and the clamping seat 500 to fix the bridge deck 300, and so on to install the bridge deck 300; when it is necessary to install the cross beam 100, give priority to installing the cross beam 100. After the cross beam 100 is installed, start installing the bridge deck 300. When the bridge deck 300 of a section of the guardrail 600 on the bridge surface is paved, start installing the guardrail 600. And so on. When the bridge deck 300 is laid to the position of the cross beam 100, give priority to assembling the cross beam 100. Among them, the cross beam 100 is a T-shaped steel. After the longitudinal beam 200 is laid in place, the cross beam 100 can be inserted downward from the upper part into the clamping groove fixed on the longitudinal beam 200 and can be easily placed in place. Connect the longitudinal beam 200 and the cross beam 100 with bolts, and the installation of the cross beam 100 and the bridge deck 300 can be constructed simultaneously from both ends of the bridge; after the bridge deck 300 is assembled, carry out the bridge deck paving, and the bridge deck paving uses 1 cm thick quartz sand.

[0086] Among them, the guardrail 600 is installed simultaneously when laying the bridge deck 300. After the clamping seat 500 is assembled in place, install the corresponding guardrail 600. In this way, there is edge protection during construction, making the construction safer.

[0087] Among them, the cross beam 100 is not installed and then the bridge deck 300 is laid. Instead, the bridge deck 300 is laid as soon as one cross beam is installed. When it is necessary to install a cross beam, the cross beam is preferentially installed. That is to say, after the longitudinal beam 200 is installed, the bridge deck 300 is laid from both ends of the bridge deck. If it is necessary to install the cross beam 100, the cross beam 100 is preferentially installed. Otherwise, the bridge deck 300 is installed. Due to the presence of the bridge deck 300, the assembly of the cross beam 100 will be easier. The bridge deck 300 is paved to the section length of a guardrail 600 and then the guardrail 600 is installed. After the guardrail 600 is installed, the cross beam 100 and the bridge deck 300 are installed again.

[0088] It should also be pointed out that the high-efficiency and quick-assembly pedestrian bridge provided in this embodiment is simple and easy to assemble. Except for the installation of the longitudinal beam 200 of the long-span pedestrian bridge, no large hoisting equipment is required. Components such as the cross beam 100 and the bridge deck 300 can be easily moved and installed by two people. Ordinary workers who do not understand bridge technology can complete the assembly within three to five days without interrupting traffic. For example, a single longitudinal beam 200 with a length of 25m weighs about 6.5 tons, a single cross beam 100 weighs about 60kg, and a single bridge deck 300 weighs about 20kg. During construction, except for the longitudinal beam 200 that requires a small crane, the rest can be manually carried. During the assembly work, only one 10-ton crane, 2 workers and 1 technician are required. The installation and hoisting time of the longitudinal beam 200 is 1 day, and the installation time of the bridge deck 300, the fixing strip 400, the clamping seat 500 and the cross beam 100 is 2.5 days, and the installation time of the guardrail 600 and the bridge deck paving is 0.5 days. Moreover, the installation of the cross beam 100 and the bridge deck 300 can be carried out synchronously from both ends of the pedestrian bridge. In case of emergency, more personnel can be invested to compress the construction period to 2 days or even shorter.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
