Description

Technical Field

[0001] This utility model relates to the technical field of bridge protection devices, and in particular to an integral bridge railing for the central median strip. Background Technology

[0002] Highway guardrails serve as the last line of defense in the event of an accident involving out-of-control vehicles, providing blocking, guidance, and cushioning functions. They play a vital role in reducing the severity of accidents and minimizing loss of life and property.

[0003] In highway construction, considering structural safety and stress factors, bridges are often built in a split-span configuration, meaning the opposing lanes are separated into two independent bridges. In split-span bridge construction, guardrails are typically installed on both the left and right sides of the central median. Existing technologies have the following problems:

[0004] 1. High construction costs and long construction period: Installing guardrails on both sides of the bridge increases the amount of materials used and the amount of construction work.

[0005] 2. The gap between the two bridge spans cannot be effectively utilized: the gap space is not used rationally, resulting in a waste of resources;

[0006] 3. There is a risk of trapped personnel falling into the gaps in the middle of the bridge.

[0007] To address the aforementioned technical issues, and considering the functional requirements of highway median guardrails, the site conditions and structural requirements of split-span bridges, as well as factors such as safety, ease of construction, and economy, an integral median bridge guardrail is proposed.

[0029] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] See Figures 1-5 This utility model provides a technical solution:

[0031] Example:

[0032] like Figures 1-5 As shown, an integral bridge railing for the central median includes a base 1, a first crossbeam 2, and multiple columns 3 (the columns 3 are C-shaped steel). The base 1 is fixedly installed at the central median and connected to the bridge deck 18 on both sides of the central median.

[0033] The first crossbeam 2 is connected to the base 1 as a whole by multiple columns 3.

[0034] like Figures 1-3 As shown, the base 1 has a cross-section in the shape of a "Z". The base 1 includes a top plate 4, support plates 5 disposed on both sides of the top plate 4, and connecting plates 6 respectively connected to the support plates 5. The connecting plates 6 are attached to and fixed to the bridge deck 18.

[0035] The top plate 4 is provided with mounting holes 7 that are adapted to the column 3. The lower end of the column 3 extends into the base 1 through the mounting holes 7. A flange plate 8 is fixedly provided on the outside of the column 3, and the flange plate 8 is fixed to the top plate 4.

[0036] like Figure 2 , Figure 4 and Figure 5 As shown, it also includes a positioning seat 9 and a support seat 10. The two ends of the support seat 10 are respectively disposed in the bridge panel 18 on both sides of the central divider. The positioning seat 9 is disposed on the top of the support seat 10. The positioning seat 9 includes a base plate 19 and side plates 20 disposed on both sides of the base plate 19. The two side plates 20 and the base plate 19 form a positioning groove 11 for positioning the column 3. The bottom end of the column 3 is supported by the base 1.

[0037] The positioning seat 9 is connected to the positioning seat 9 by a first bolt 12, which extends into the bridge deck 18.

[0038] like Figure 1 As shown, the first crossbeam 2 is fixedly connected to the top of the column 3. The first crossbeam 2 is a C-shaped steel, and the open end of the first crossbeam 2 faces the base 1.

[0039] like Figure 1 and Figure 2 As shown, a C-shaped connecting sleeve 13 is fixedly (welded) on the column 3. The opening end of the connecting sleeve 13 is set downward, and the opening of the connecting sleeve 13 is adapted to the column 3. The connecting sleeve 13 is provided with a first connecting hole. The first crossbeam 2 is provided with a second connecting hole corresponding to the first connecting hole. The first crossbeam 2 is fixed to the column 3 by a second bolt 14, the first connecting hole, the second connecting hole, and the connecting sleeve 13.

[0040] like Figure 1 and Figure 2 As shown, it also includes two second crossbeams 15, which are C-shaped steel beams. The two second crossbeams 15 are respectively arranged on both sides of the column 3, and the openings of the two second crossbeams 15 are arranged opposite each other. The second crossbeams 15 are fixedly connected to the column 3 by bolts.

[0041] Two adjacent bases 1 are connected by a splicing plate 16 and a third bolt, and two adjacent first crossbeams 2 are connected by a sleeve 17 and a fourth bolt. The splicing plate 16 is a straight plate with through holes, and the base 1 also has through holes. The third bolt passes through the through holes, and both ends of the splicing plate 16 are connected to the two adjacent bases 1 respectively. The sleeve 17 is a C-shaped steel tube with through holes on three sides, and the connection method is the same as that of the splicing plate 16.

[0042] Among them, 1. The support base 10 is a rectangular steel structure. In order to reduce the counterweight, a weight-reducing groove is set at the bottom of the support base 10.

[0043] When in use: (1) When the bridge body is formed, the two ends of the support seat 10 can be pre-embedded in the bridge deck 18 on both sides of the central divider (or the installation groove for the support seat 10 can be reserved on the bridge deck). After the support seat 10 is in place, the positioning seat 9 is installed on the support seat 10 by the first bolt 12. The first bolt 12 not only connects the support seat 10 and the positioning seat 9, but also strengthens the connection between the positioning seat 9 and the bridge deck 18.

[0044] (2) Press the connecting plate 6 of the base 1 onto the bottom plate 19 of the positioning seat 9, and make the mounting hole 7 correspond to the positioning groove 11 vertically. The first bolt 12 passes through the connecting plate 6, the bottom plate 19 and the support seat 10 in sequence and then enters the bridge panel 18.

[0045] (3) After the bottom end of the column 3 passes through the mounting hole 7, it is placed into the positioning groove 11, and the positioning seat 9 and the support seat 10 provide support for the column 3. At the same time, the flange plate 8 on the outside of the column 3 is connected and fixed to the base 1 by bolts, which further improves the stability of the column 3 and limits the horizontal and vertical movement of the column 3.

[0046] (4) Fix the second crossbeam 15 to the column 3 with bolts.

[0047] (5) Slide the opening of the first crossbeam 2 into the connecting sleeve 13, so that the connecting sleeve 13 enters the first crossbeam 2. The connecting sleeve, together with the column 3, provides support for the first crossbeam 2. Insert the second bolt 14 until the second connecting holes on the first crossbeam 2 correspond one-to-one with the first connecting holes. After the second bolt 14 is inserted, since the column 3 is a channel steel structure, its open part can provide operating space for tightening the nut. When the column 3 is a square steel structure, the nut can be fixed in advance at the position corresponding to the first connecting hole of the column 3, or the first connecting hole can be set as a threaded hole.

[0048] (6) When the guardrail is extended, the adjacent base 1 is connected by splicing plate 16, and the crossbeam is connected by C-shaped steel (sleeve 17) with a size that matches its opening.

[0049] This utility model features an integrated steel structure guardrail, which is lightweight and easy and quick to install. The base has a U-shaped shell structure, which, together with the support and positioning seats, ensures the overall strength of the guardrail while significantly reducing its overall weight, thereby reducing the load on the bridge.
