Description

Technical Field

[0001] This application pertains to the field of building construction, specifically to a type of temporary underwater walkway. Background Technology

[0002] With the continuous development of tourism, boardwalks are increasingly used in mountain and coastal landscapes. Currently, boardwalks are mainly made of wood, steel, and transparent tempered glass. The boardwalks built in various scenic areas serve the purpose of providing a convenient path for tourists to walk and enjoy the scenery.

[0003] In some landscape lakes, where the boardwalks are not yet completed, temporary boardwalks are needed to provide access for heavy machinery and materials, and to serve as a working platform for construction workers, facilitating the construction of the boardwalks. Utility Model Content

[0004] The purpose of this utility model is to provide a temporary underwater walkway, which can serve as a working platform for construction workers and a platform for transporting equipment and building materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A temporary underwater walkway, characterized in that it comprises a lower H-shaped steel support frame, H-shaped steel beam supports mounted on the lower H-shaped steel support frame, and railings. The H-shaped steel beam supports include transverse H-shaped steel main beams and longitudinal H-shaped steel main beams. The connection nodes of the transverse and longitudinal H-shaped steel main beams are T-shaped or cross-shaped. The ends of the T-shaped or cross-shaped connection nodes are connected by straight connecting plates. The straight connecting plates pass through the ends of the webs of the T-shaped vertical main beams and are bolted to the webs of the transverse main beams on both sides. The lower H-shaped steel support frame includes horizontal bars, bracing bars, and vertical steel pipes. The vertical steel pipes are driven into the silt. The vertical steel pipes are clamped on both sides of the transverse and longitudinal H-shaped steel main beams. The horizontal bars include transverse and longitudinal bars, which are connected between the vertical steel pipes.

[0007] More preferably, the horizontal bar has two layers, located at the bottom of the beam and the water surface respectively, and one of every three vertical steel pipes is a double bar.

[0008] Furthermore, the strut is obliquely positioned between the vertical steel pipe and the original soil layer below the silt.

[0009] Furthermore, it also includes square steel secondary joists and plastic boards laid sequentially on the H-shaped steel beam supports.

[0010] Furthermore, the railing includes uprights and I-shaped crossbars connected between the uprights, with a frame provided between the upper and lower I-shaped crossbars.

[0011] More preferably, the uprights are made of 100*100*3mm galvanized steel pipes, the I-shaped crossbars are made of 40*60*3mm galvanized steel pipes and are welded and fixed to the H-shaped steel beams for support, the frame is made of 25*25*2mm galvanized steel pipes, and the entire railing is sprayed with antique red matte fluorocarbon paint.

[0012] Compared with the prior art, this utility model has the following features and beneficial effects:

[0013] Except for the welded connection between the railing and the main beam, all other structures in this application are bolted together. The uprights are supported on both sides of the main beam, and the main beam is not fixed. No welding machine or bolting is required, making installation and disassembly convenient and easy to transport. The structure is simple, ensuring the overall rigidity and strength of the walkway. It has the characteristics of safety and applicability, and has good promotion and practical value. Widespread promotion and application will generate good economic benefits.

[0020] The embodiments described herein are specific implementations of this utility model, used to illustrate the concept of this utility model. They are all illustrative and exemplary, and should not be construed as limiting the implementation methods or scope of this utility model. In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application. These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein.

[0021] A temporary underwater walkway, with a water depth of 1.2m~1.4m and a silt depth of 0.5m~0.7m, such as... Figures 1-5As shown, it includes a lower H-beam support frame 1, an H-beam beam support 3 mounted on the lower H-beam support frame 1, and railings 2. The railings 2 are located on both sides of the walkway. The H-beam beam support 3 includes a transverse H-beam main beam 31 and a longitudinal H-beam main beam 32. The connection nodes of the transverse H-beam main beam 31 and the longitudinal H-beam main beam 32 are T-shaped or cross-shaped. The ends of the T-shaped or cross-shaped connection nodes are connected by a straight connecting plate 33. The straight connecting plate 33 passes through the end of the web of the T-shaped vertical main beam and is bolted to the web of the transverse main beams on both sides.

[0022] The lower H-beam support frame 1 includes horizontal bars 11, bracing bars 12, and vertical steel pipes 13. The lower part of the vertical steel pipes 13 is driven into the silt. The vertical steel pipes 13 are clamped on both sides of the bottom plate of the transverse H-beam main beam 31 and the longitudinal H-beam main beam 32, so that the entire transverse H-beam main beam 31 and the longitudinal H-beam main beam 32 are clamped on both sides of the vertical steel pipes 13. The horizontal bars 11 include horizontal and vertical bars, which are connected between the vertical steel pipes 13. The horizontal bars 11 have two layers, located at the bottom of the beam and the water surface, respectively. One of every three vertical steel pipes 13 is a double bar. The bracing bars 12 are set diagonally between the vertical steel pipes 13 and the original soil layer below the silt. It also includes square steel secondary keels 4 and plastic board boards 5 laid sequentially on the H-beam support 3. The two sides of the walkway are wrapped with plastic board boards 4 so that the H-beams are hidden in the plastic board boards 4. The square steel secondary keels 4 are galvanized square steel and are fixed to the H-beam main beams by angle brackets and screws.

[0023] The railing 2 includes uprights 21 and I-shaped crossbars 22 connected between the uprights 21, with a total height of approximately 1.3m. A frame 23 is provided between the upper and lower I-shaped crossbars 22.
