Description

Technical Field

[0001] The utility model relates to the field of bridge guardrails, in particular to an assembled bridge guardrail. Background Art

[0002] Bridge guardrails refer to guardrails installed on bridges. Their purpose is to prevent out-of-control vehicles from going over the bridge. They have the function of preventing vehicles from breaking through, passing under, or climbing over the bridge, as well as beautifying the bridge structure. They can also be used as handrails to prevent pedestrians from accidentally falling.

[0003] Existing bridge guardrails are generally fixed by drilling holes and then bolting. This installation method has limited protection against out-of-control vehicles and is not strong enough. There are also bridge guardrails that use embedded parts to connect and fix the guardrails, but the embedding of embedded parts is not as precise as drilling. After the embedded parts are fixed to the columns, there will often be errors in the distance between the columns. It is not convenient to bolt the columns and beams, and they often need to be cut or directly fixed by welding. This is an existing problem. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art, the utility model provides an assembled bridge guardrail, the guardrail columns can be adjusted according to the positions of embedded parts, no cutting and welding are required, and the installation is more convenient, so as to improve the existing problems.

[0005] The utility model is realized through the following technical solutions:

[0006] An assembled bridge guardrail includes an abutment, wherein a plurality of embedded parts are embedded and fixed in the abutment, columns are fixed to the plurality of embedded parts by bolts, a plurality of beams are fixed to the columns, the beams are hollow and tubular, and a fixing opening is provided on one side of the beams, a plurality of vertical connection holes are provided at each end of the beams, a connecting fixture that can slide freely is provided in the beams, a fixing screw hole is provided on one side of the connecting fixture, and a connecting screw hole that penetrates vertically is provided on the connecting fixture, the connecting fixture is used to fix the beams and the columns, and is also used for fixed connection between the beams.

[0007] For further optimization, strip-shaped fixing holes are provided on both sides of the column, and the column is fixed to the connecting fixings in the beam through the strip-shaped holes, fixing screw holes and fixing bolts.

[0008] For further optimization, a right-angle auxiliary plate is also fixed to the bottom of the column.

[0009] In a further optimized manner, the inner diameter of the cross beam is matched to the outer diameter of the connecting and fixing member, and the outer wall of the connecting and fixing member is in close contact with the inner wall of the cross beam.

[0010] In a further optimized manner, three cross beams are provided.

[0011] Further optimized, the three cross beams include an upper cross beam, a middle cross beam and a lower cross beam, and the diameters decrease successively from top to bottom.

[0012] For further optimization, three connection holes are respectively provided at both ends of the upper cross beam, and six connection screw holes are provided on the connection fixing piece of the upper cross beam, and the upper cross beams are fixedly connected by the connection fixing piece and bolts.

[0013] The beneficial effects of the utility model are:

[0014] By connecting the fixings to fix the columns and beams, the requirements for the spacing accuracy of the columns are not high, so the requirements for the initial construction accuracy of the spacing of the embedded parts are not high. The columns can be fixed according to the positions of the embedded parts, and then the beams are installed through the connecting fixings. The guardrail is more convenient to disassemble and assemble, and the guardrail is more secure; the beams are also connected by connecting fixings. The entire installation process does not require cutting and welding, which saves installation steps and has higher installation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

During the construction of the abutment 1, a number of embedded parts 6 are pre-buried, and screw holes are provided on the embedded parts. The columns 2 are fixed to the embedded parts by bolts, which is more firm than drilling construction.

[0023] A plurality of beams 3 are fixed on the upright column 2. The beams 3 are hollow and tubular, and a fixing opening 8 is provided on one side of the beams. A plurality of vertical connection holes 31 are provided at both ends of the beams 3. A freely slidable connecting fixture 4 is provided inside the beams 3. A fixing screw hole 42 is provided on one side of the connecting fixture. A vertically penetrating connecting screw hole 41 is also provided on the connecting fixture 4. When the connecting fixture 4 is located inside the beams 3, the beams 3 and the upright column 2 can be fixed by the fixing screw hole 42. When the connecting fixture 4 is located at the end of the beams, the two beams can be fixedly connected transversely by the connecting screw hole 41.

[0024] As a preferred embodiment, Figure 3 , 4 As shown in Figures 5 and 6, strip-shaped fixing holes 21 are provided on both sides of the column 2. The column 2 is fixed to the connecting fixture 4 in the beam 3 through the strip-shaped holes 21, the fixing screw holes 42 and the fixing bolts 7, so that the beam is fixed to the column. The connecting fixture 4 can slide freely inside the beam before fixing, so the spacing requirements for the columns are not high during fixing, the installation is more convenient, and the construction difficulty of the embedded parts is reduced.

[0027] As a preferred embodiment, Figure 1 , 4 As shown, there are three cross beams 3, including an upper cross beam, a middle cross beam and a lower cross beam, and the diameters decrease from top to bottom. It should be noted that the connecting and fixing parts of the upper cross beam, the middle cross beam and the lower cross beam are of different models. The middle cross beam and the lower cross beam ensure firmness while reducing materials and costs. The inner side of the upper cross beam is curved, which is convenient for pedestrians to hold, and the design is more humane.
