Description

Technical Field

[0001] The utility model belongs to the technical field of metal guardrails, and particularly relates to a metal guardrail with a reinforced fixing base. Background Art

[0002] Most metal guardrails are fixed to the ground by expansion bolts or embedding, and are usually installed on both sides of logistics channels, around production equipment, building corners, both sides of doors, and the edges of loading platforms, etc.

[0003] Most metal guardrails are composed of a fixing base, a column, and a cross bar. The fixing base is fixed on the ground and supports the column. Most of the existing guardrail columns are tubular structures, and the structural strength at the connection between the column and the fixing base is low. When being impacted, the connection part is easy to break. Moreover, most of the metal guardrail fixing bases are fixed to the ground by expansion bolts, and under the long-term vibration of the road surface, the fixing base is easy to loosen from the ground.

[0004] Therefore, a metal guardrail with a reinforced fixing base is proposed. Content of the Utility Model

[0005] The utility model provides a metal guardrail with a reinforced fixing base, aiming to solve the above problems.

[0006] The utility model is realized as follows: A metal guardrail with a reinforced fixing base includes: a fixing base; a docking platform integrally formed at the central position on the top of the fixing base; a column slot opened on the top of the docking platform; a threaded hole opened at the central position on the top of the docking platform; a threaded column screwed into the threaded hole by threads; a reinforced inner column welded to the top end of the threaded column; a storage cavity opened at the central position on the bottom of the fixing base; an inner limiting groove opened at a position inside the fixing base directly above the storage cavity; a base arranged at a position below the fixing base; a limiting plate integrally formed on the top of the base; a column inserted into the column slot; a first docking hole opened on the outer side wall of the column; a second docking hole opened on the outer side wall of the docking platform; a cross bar fixed to the outer side wall of the column by bolts; and a rod plug embedded in the top of the column.

[0007] Preferably, the cross sections of the column slot and the column are both rectangular frame structures.

[0008] Preferably, the column and the docking platform are fixedly connected by fastening bolts, and the fastening bolts penetrate through the first docking hole and the second docking hole.

[0009] Preferably, the cross section of the fixing base is an isosceles trapezoid structure.

[0010] Preferably, the outer side wall of the reinforced inner column is in contact with the inner side wall of the column.

[0011] Preferably, the base can rotate 90 degrees inside the storage cavity, and the limiting plate can rotate 90 degrees inside the inner limiting groove.

[0012] Compared with the prior art, the embodiments of the present application mainly have the following beneficial effects:

[0013] By strengthening the inner column to fit against the inner side wall of the column to provide support for the column, it avoids the problem of low structural strength caused by the hollow structure of the column at the connection between the column and the docking platform, ensures the structural strength, and avoids fracture due to impact. By embedding the limiting plate into the inside of the limiting fixing seat, it provides a limiting binding force for the fixing seat in the vertical direction, and uses double fixation to ensure the stability of the connection between the fixing seat and the ground, avoiding the problem of bolt loosening caused by long-term ground vibration.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments, and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects, rather than to describe a specific order.

[0020] References to "embodiments" in this specification mean that the particular features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] An embodiment of the present utility model provides a metal guardrail with a reinforced fixing seat, as Figures 1-4 shown, including a fixing seat 1. The cross-section of the fixing seat 1 is an isosceles trapezoid structure. The fixing seat 1 with a larger bottom and a smaller top can provide a more stable and firm support. A docking platform 2 is integrally formed at the top of the fixing seat 1. A column socket 3 is opened at the top of the docking platform 2, and a threaded hole 4 is opened at the inner side of the central position of the top of the docking platform 2 near the column socket 3. A threaded column 5 is threadedly connected inside the threaded hole 4. A reinforced inner column 6 is welded to the top of the threaded column 5. A storage cavity 7 is opened at the central position of the bottom of the fixing seat 1, and an inner limiting groove 8 is opened at the position above the storage cavity 7 inside the fixing seat 1. A base 9 is arranged inside the storage cavity 7. A limiting plate 10 is integrally formed at the top of the base 9. A column 11 is inserted into the column socket 3. The cross-sections of the column socket 3 and the column 11 are both rectangular frame structures. A first docking hole 12 is opened on the outer wall of one side of the column 11. A second docking hole 13 is opened on the outer wall of one side of the docking platform 2 at the horizontal side near the first docking hole 12. A cross bar 14 is fixedly connected to the outer wall of one side of the column 11 by bolts, and a rod plug 15 is embedded at the top of the column 11.

[0022] It should be noted that since most of the existing guardrail columns are tubular structures, the structural strength at the connection between the column and the fixing seat is low, and the connection is prone to breakage when impacted. Moreover, most of the metal guardrail fixing seats are fixed to the ground by expansion bolts, and the fixing seat is prone to loosen from the ground under long-term road vibrations. In this embodiment, the reinforced inner column 6 fits against the inner side wall of the column 11 to provide support for the column 11, avoiding the problem of low structural strength caused by the hollow structure of the column 11 at the connection between the column 11 and the docking platform 2, ensuring the structural strength and avoiding fracture when impacted. By embedding the limiting plate 10 into the fixing seat 1, a limiting binding force is provided for the fixing seat 1 in the vertical direction, and the double fixation is used to ensure the stability of the connection between the fixing seat 1 and the ground, avoiding the problem of bolt loosening caused by long-term ground vibrations.

[0023] Specifically, in this embodiment, the solution mainly includes a reinforcing inner column 6 and a limiting plate 10. When in use, first fix the base 9 at the position where the metal guardrail needs to be installed by using expansion bolts. After the preliminary fixation of the base 9, put the sleeve at the bottom of the fixing seat 1 on the outside of the base 9, and insert the limiting plate 10 into the inner limiting groove 8. At this time, rotate the fixing seat 1 by 90 degrees, and the limiting plate 10 rotates by 90 degrees inside the inner limiting groove 8. Since the cross-section of the limiting plate 10 is a cuboid structure, after the limiting plate 10 rotates by 90 degrees, the insertion port of the limiting plate 10 and the inner limiting groove 8 are misaligned, thereby realizing the limiting connection between the limiting plate 10 and the fixing seat 1. Then fix the fixing seat 1 on the ground by using expansion bolts to achieve the double fixation of the fixing seat 1. Through the threaded engagement connection between the threaded hole 4 and the threaded post 5, screw the threaded post 5 into the threaded hole 4, fix the column 11 on the top of the docking platform 2, and make the outer side walls of the column 11 and the docking platform 2 coincide. Insert the column 11 into the column slot 3 at the top of the docking platform 2, and use the fastening bolt to pass through the first docking hole 12 and the second docking hole 13 to fixedly connect the column 11 and the docking platform 2. After fixing the cross bar 14 on the column 11, assemble the metal railing.

[0024] In a further preferred embodiment of the present utility model, as Figure 1 shown, the column 11 and the docking platform 2 are fixedly connected by a fastening bolt, and the fastening bolt passes through the first docking hole 12 and the second docking hole 13.

[0025] In this embodiment, the fixing connection between the column 11 and the docking platform 2 is realized through the fastening bolt, avoiding the detachment of the connection between the column 11 and the docking platform 2.

[0026] In a further preferred embodiment of the present utility model, as Figures 2-3 shown, the outer side wall of the reinforcing inner column 6 is in contact with the inner side wall of the column 11.

[0027] In this embodiment, by fitting the reinforcing inner column 6 on the inner side wall of the column 11, support can be provided for the column 11, thereby avoiding the problem of low structural strength caused by the hollow structure of the column 11 at the connection between the column 11 and the docking platform 2 and ensuring the structural strength.

[0028] In a further preferred embodiment of the present utility model, as Figure 2 and Figure 4 shown, the base 9 can rotate by 90 degrees inside the storage cavity 7, and the limiting plate 10 can rotate by 90 degrees inside the inner limiting groove 8.

[0029] In this embodiment, after being fixed to the ground through the base 9, the receiving cavity 7 at the bottom of the fixing base 1 is sleeved outside the base 9 and the limiting plate 10. The limiting plate 10 is inserted into the inner limiting groove 8. The fixing base 1 is rotated 90 degrees at the bottom. The limiting plate 10 rotates 90 degrees inside the inner limiting groove 8. Since the cross-section of the limiting plate 10 is a cuboid structure, after the limiting plate 10 rotates 90 degrees, the insertion port of the limiting plate 10 and the inner limiting groove 8 are misaligned, thereby realizing the limiting connection between the limiting plate 10 and the fixing base 1.
