Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to an adjustable construction isolation guardrail. Background Art

[0002] In the construction of municipal roads, in order to improve the safety of the construction process, it is necessary to enclose isolation guardrails around the construction site for protection, and at the same time play a role in informing pedestrians or vehicles to stay away from the construction site. Most of the existing isolation guardrails are splicing structures, that is, two guardrails are connected by columns to extend the isolation guardrail. The column and the guardrail can be fixed by welding or connected by hinges. Among them, the welding has high stability, but the guardrail cannot be adjusted after welding, while the hinged one has high adjustability and wide adaptability, but the stability is poor after connection. In view of this, this application proposes an adjustable construction isolation guardrail with both adjustability and stability. Summary of the Utility Model

[0004] To achieve the above purpose, the utility model provides the following technical solution: an adjustable construction isolation guardrail, including a guardrail body and columns. The left and right sides of the guardrail body are respectively connected with a first connecting piece and a second connecting piece, and the first connecting piece and the second connecting piece are arranged at a height difference. The ends of the first connecting piece and the second connecting piece far away from the guardrail body are both provided with connecting rings. The end face of the connecting ring is connected with a plurality of shrinking pieces. There is a cutting slit between adjacent two shrinking pieces. The inner walls of the shrinking pieces enclose a cylindrical surface. The outer walls of the tightening pieces are jointly provided with external threads, and an adjusting nut is connected to the external threads. The column is in a cylindrical structure and passes through the connecting ring, and a base is arranged at the bottom of the column.

[0005] Optionally, the lower end face of the connecting ring is connected with a plurality of shrinking pieces, and the column is detachably connected with the base.

[0006] Optionally, the column is in a circular tube structure and an internal thread section is opened at the bottom, and a threaded column adapted to the internal thread section is fixedly connected to the base.

[0007] Optionally, an annular limiting groove is opened on the outer wall of the column, and a positioning plate is arranged in front of the guardrail body. The positioning plate is used to fix a warning sign. Elastic claws are connected to both sides of the back of the positioning plate, and the elastic claws are elastically clamped and matched with the limiting groove.

[0008] Optionally, the height of the limiting groove is at least twice the height of the elastic claw.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] In the utility model, connecting rings are connected on both sides of the guardrail body, and shrinkage plates, cut slits and external threads are arranged on the connecting rings. After adjusting the angle between the two guardrail bodies, the columns are passed through, and then the adjusting nuts are tightened on the outer walls of the shrinkage plates, so that the shrinkage plates are clamped on the outer walls of the columns, thereby achieving a tightened state and realizing stability after adjustment.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Example: See Figures 1-3As shown in the figure, the present utility model provides an adjustable construction isolation guardrail, which includes a guardrail body 1 and a column 2. First connectors 11 and second connectors 12 are respectively connected to the left and right sides of the guardrail body 1. Both the first connectors 11 and the second connectors 12 are in sheet-like structures, and the first connectors 11 and the second connectors 12 are arranged in a height offset manner. Connecting rings 13 are fixedly connected to the ends of the first connectors 11 and the second connectors 12 away from the guardrail body 1. A plurality of shrinkage sheets 131 are connected to the end faces of the connecting rings 13. A cutting slit 132 is provided between adjacent shrinkage sheets 131. The inner walls of the shrinkage sheets 131 enclose a cylindrical surface, and external threads 133 are commonly provided on the outer walls of the shrinkage sheets. An adjusting nut (not shown in the figure) is connected to the external threads 133. The column 2 is in a cylindrical structure and is inserted through the connecting ring 13. A base 22 is provided at the bottom of the column 2. When in use, first place the positions and angles of two adjacent guardrail bodies 1, and at the same time align the two connecting rings 13 vertically and horizontally, and insert the column 2 through the aligned connecting rings 13. Then screw the adjusting nut tightly on the outer wall of the shrinkage sheet 131 so that the shrinkage sheet 131 clamps on the outer wall of the column 2, thereby reaching a tightened state. Therefore, the angle of the guardrail body 1 can be conveniently adjusted before tightening the adjusting nut for this adjustable construction isolation guardrail, and the stability of the guardrail body 1 can be improved after tightening the adjusting nut, and the structural design is reasonable.

[0017] Based on the above embodiment, a plurality of shrinkage sheets 131 are connected to the lower end face of the connecting ring 13, and the column 2 and the base 22 are detachably connected. Specifically, the column 2 is in a circular tube structure and an internal thread section is provided at the bottom. A threaded post 23 adapted to the internal thread section is fixedly connected to the base 22. Since the shrinkage sheets 131 are arranged downward, it is convenient to insert the bottom of the column 2 downward along the uppermost connecting ring 13. After being inserted in place, thread the bottom of the column 2 with the threaded post 23 on the base 22. The stability of the column 2 during support can be improved after installing the base 22.

[0018] Based on the above embodiment, an annular limiting groove 21 is provided on the outer wall of the column 2. A positioning plate 3 is provided in front of the guardrail body 1. The positioning plate 3 is used to fix a warning sign. Elastic claws 31 are connected to both sides of the back of the positioning plate 3. The elastic claws 31 are elastically clamped and matched with the limiting groove 21. The height of the limiting groove 21 is at least twice the height of the elastic claws 31. Among them, the elastic claws 31 and the limiting groove 21 are also a detachable structure. Therefore, the positioning plate 3 can be installed according to the actual situation. By limiting the height of the limiting groove 21, multiple positioning plates 3 can be arranged vertically and horizontally in a staggered manner along the width direction of the isolation guardrail, thereby extending the length on which the warning sign can be fixed. The warning sign can also be fixed by means such as hooks, clips or screws.

[0019] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
