[0036] Please refer to the attached Figure 1-7In one embodiment of the utility model, a bridge railing structure for a landscape bridge includes a guardrail structure 20 and a plurality of column units 10 arranged at intervals along the longitudinal direction of the bridge. First of all, it should be noted that the bridge railing structure in the present application is mainly used for the sidewalk of the landscape bridge, and the anti-collision railing of the carriageway is arranged on the inner side of the sidewalk (not shown); which is different from the railings used for landscape bridges in the prior art, which usually focus on the aesthetic effect, and the connection treatment is relatively simple during installation and construction. Therefore, after a long period of use or with the displacement and deformation of the bridge, the connection between the railing and the bridge is prone to loosening, resulting in unstable installation of the railing and increasing the frequency and cost of subsequent maintenance. The present application solves the above-mentioned defects in the prior art by providing a bridge railing structure for a landscape bridge. The details are as follows:

[0037] Each of the column units 10 includes a column assembly 110, an embedded steel plate 120, an embedded bolt 130 and a reinforcement assembly 140, wherein the reinforcement assembly 140 includes an embedded threaded barrel 141, and the guardrail structure 20 is arranged between two adjacent column assemblies 110, wherein the column assembly 110 is fixed to the embedded steel plate 120, and the embedded steel plate 120 is provided with bolt holes 121 distributed in a matrix shape, and the embedded threaded barrel 141 is fixed to the bottom of the embedded steel plate 120. It is arranged corresponding to the bolt hole 121, and the embedded threaded barrel 141 has an internal thread, the embedded bolt 130 has an external thread matching the internal thread, and the embedded steel plate 120 passes through the bolt hole 121 and the embedded threaded barrel 141 in sequence through the embedded bolt 130 to be embedded in the outer seat 30 of the bridge sidewalk; the side wall of the embedded threaded barrel 141 is formed with an annular flange 142 outwardly, and the annular flange 142 abuts against the concrete in the outer seat 30 of the bridge sidewalk.

[0038] Specifically, the bridge railing structure for a landscape bridge in the present application includes a guardrail structure 20 and a plurality of column units 10, wherein the column units 10 are used for installing the guardrail structure 20, and the entire bridge railing structure is fixed to the bridge through the column units 10, so that the plurality of column units 10 are arranged at intervals along the longitudinal direction of the bridge, so that the guardrail structure 20 is connected between two adjacent column units 10, thereby forming an integral bridge guardrail structure 20.

[0039] Among them, each of the column units 10 includes a column assembly 110, an embedded steel plate 120, an embedded bolt 130 and a reinforcement assembly 140. The column assembly 110 is used for fixing and installing the guardrail structure 20. It can be installed on the embedded steel plate 120 by welding. The embedded steel plate 120 is pre-embedded in the outer seat 30 of the bridge sidewalk in advance, and a bolt hole 121 is provided for the embedded bolt 130 to be pre-embedded and anchored in advance. A plurality of the bolt holes 121 are distributed in a matrix shape to be evenly arranged to ensure a stable connection. When the embedded steel plate 120 and the embedded bolt 130 are pre-embedded for concrete pouring, the embedded bolt 130 may be offset, thereby failing to ensure the stability of the anchoring installation. Therefore, the reinforcing assembly 140 can be used to further strengthen the limit. As a preferred embodiment of the present application, the reinforcing assembly 140 includes The embedded threaded barrel 141 is fixed to the bottom of the embedded steel plate 120. In order to ensure the limiting of the embedded bolt 130, the embedded threaded barrel 141 is corresponding to the bolt hole 121. The corresponding setting here means that the position of the embedded threaded barrel 141 is correspondingly set below the bolt hole 121, and the internal thread of the embedded threaded barrel 141 (not shown in the figure) is consistent with the size of the bolt hole 121 and is coaxially arranged. In this way, after the embedded bolt 130 is penetrated, it can only extend vertically through the limitation of the embedded threaded barrel 141, and will not be disturbed by external factors and thus deviate; preferably, the embedded bolt 130 has an external thread (not shown in the figure) matching the internal thread, so that the embedded bolt 130 is more stable after being penetrated by the embedded threaded barrel 141 through the threaded fitting connection to avoid loosening.

[0040] Furthermore, an annular flange 142 is protrudingly formed on the outer side of the embedded threaded tube 141. After the concrete pouring in the bridge sidewalk outer seat 30 reaches a certain strength, the annular flange 142 and the concrete are mutually supported. Since the contact area between the annular flange 142 and the concrete increases, the concrete applies pressure to the annular flange 142 in the vertical direction, thereby better preventing the entire component from loosening in the vertical direction and enhancing the connection and installation of the entire bridge guardrail.

[0041] As a preferred embodiment of the present invention, the annular flange 142 protrudes upward to form a plurality of retaining blocks 143 , and the plurality of retaining blocks 143 are arranged at intervals along the circumference of the annular flange 142 .

[0042] It should be noted that the retaining block 143 is used to enhance the anti-loosening effect in the horizontal direction. After the concrete is poured, the concrete and the retaining block 143 are mutually supported to form a horizontal lateral pressure, thereby strengthening the structural bite performance between the component and the concrete and improving the connection stability.

[0043] As a preferred embodiment of the present invention, the reinforcement assembly 140 also includes a fan ring reinforcement block 144, which is fixed between two adjacent retaining blocks 143; wherein, the first end of the fan ring reinforcement block 144 is flush with the top of one of the retaining blocks 143, and the second end of the fan ring reinforcement block 144 is flush with the bottom of the other retaining block 143, and the fan ring reinforcement block 144 forms a slope from the first end toward the second end.

[0044] It should be noted that the fan ring reinforcement block 144 is used to strengthen the connection stability between the two adjacent retaining blocks 143 and improve the bearing stability of the retaining block 143. The fan ring reinforcement block 144 is formed with a slope, which can alleviate the vertical pressure of the concrete on the annular flange 142. While ensuring mutual support, the vertical pressure is decomposed into component forces in different directions through the slope, which not only ensures the structural bite performance between the component and the concrete, but also disperses the concentrated effect of the load and enhances the structural strength.

[0045] As a preferred embodiment of the present invention, the column assembly 110 includes four square tube columns 111 . The four square tube columns 111 are arranged at intervals in a square shape and fixed on the embedded steel plate 120 .

[0046] It is worth mentioning that the square tube column 111 has the advantages of light weight and high bearing capacity. The four square tube columns 111 are arranged in a square shape to expand the column area for easy connection of the guardrail structure 20. Compared with the traditional large steel tube columns, it has the same strength but is more cost-effective.

[0047] As a preferred embodiment of the present invention, the column assembly 110 further includes a column sleeve 112 , and the column sleeve 112 is sleeved on the outside of the four square tube columns 111 .

[0048] It is worth noting that the column sleeve 112 is used to combine multiple square tube columns 111 into a whole. The multiple square tube columns 111 serve as the main load-bearing components inside, and the column sleeve 112 is sleeved on the outside of the four square tube columns 111. It is not only used as a connecting carrier to facilitate the installation and connection of the guardrail structure 20 for construction, but also can protect the square tube columns 111 inside to avoid damage, corrosion, rust, etc.

[0049] Furthermore, the guardrail structure 20 includes a longitudinal handrail 210, a longitudinal flat tube 220 and a masonry structure 230. The longitudinal handrail 210 and the longitudinal flat tube 220 are both arranged between two adjacent column sleeves 112. The longitudinal handrail 210 is connected to the top end of the column sleeve 112, and the longitudinal flat tube 220 is connected to the bottom end of the column sleeve 112. The masonry structure 230 is arranged between the longitudinal handrail 210 and the longitudinal flat tube 220, and the masonry structure 230 runs through the middle of the four square tube columns 111.

[0050] It should be noted that the longitudinal handrail 210 is used for pedestrians to support, so it is connected to the top of the column sleeve 112; and the longitudinal flat tube 220 is combined with the longitudinal handrail 210 to connect two adjacent column sleeves 112. The flat tube here refers to a square steel tube with a rectangular cross-sectional area but a low thickness, which is a commonly used component in construction; the masonry structure 230 is used as the protection area of ​​the entire guardrail structure 20 to prevent pedestrians from rushing out and falling. It can be composed of multiple glass brick masonry arranged in a plum blossom shape. The glass brick masonry not only has a protective effect but also has the characteristics of aesthetics, and is more suitable for landscape bridges.

[0051] Furthermore, the column sleeve 112 is gradually inclined inward from the top to the middle.

[0052] It should be understood that the inclined setting can reduce the deadweight of the entire column and save costs. It also creates an effect of being wide at the top and narrow at the bottom, making it more beautiful when used as a landscape bridge.

[0053] Furthermore, each of the column units 10 further includes a glass lamp 150 , and the glass lamp 150 is fixed to the top of the column sleeve 112 .

[0054] It should be noted that the glass lamp 150 can be used for bridge lighting at night, and the present application is mainly used for landscape bridges. The glass lamp 150 can be in a teacup shape, which can serve as a unique aesthetic feature of each column unit 10 to enhance the aesthetics.

[0055] Furthermore, the number of the retaining blocks 143 is four, and the four retaining blocks 143 are arranged at intervals along the circumference of the annular flange 142 .

[0056] It should be noted that too few retaining blocks 143 will lead to uneven anti-loosening effect in the horizontal direction. Considering the preferred bearing effect of the retaining blocks 143, preferably, the number of the retaining blocks 143 is four, and technical personnel in this field can choose according to actual needs.

[0057] Furthermore, the spacing distance between each two adjacent column units 10 is 3m to 4m.

[0058] It can be understood that the spacing distance between two adjacent column units 10 can be determined according to the structural stability. If the spacing distance is too long, the guardrail structure 20 will be unstable. Therefore, preferably, the spacing distance between each two adjacent column units 10 is 3m to 4m, and the maximum spacing distance can be controlled within 4m.

[0059] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent unit or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
