Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, and specifically to a guardrail. Background Technology

[0002] In modern urban spaces that prioritize people, the effectiveness of railings in public places is often overlooked. Existing railings along riverbanks only meet the safety protection requirements and cannot simultaneously satisfy the combined needs of aesthetic appeal, ergonomic comfort, and nighttime lighting in urban public spaces. Utility Model Content

[0003] The purpose of this utility model is to provide a guardrail to solve at least one of the aforementioned problems existing in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A guardrail includes a concrete balustrade panel, comprising an integrally formed inner balustrade panel, a top balustrade panel, and an outer balustrade panel. The angle A between the inner balustrade panel and the top balustrade panel is 75°. The radius of curvature R1 between the inner balustrade panel and the top balustrade panel is 80mm. The angle B between the top balustrade panel and the outer balustrade panel is 105°. The radius of curvature R2 between the top balustrade panel and the outer balustrade panel is 80mm. The angle C between the outer balustrade panel and the horizontal plane is 85°. The radius of curvature R3 at the lower end of the outer balustrade panel is 85mm. The outer balustrade panel is a translucent concrete balustrade panel. The height H1 of the concrete balustrade panel is 1050mm. The outer balustrade panel also has a light source mounting hole with a height H2 of 250mm and a diameter of 50mm.

[0006] This technical solution features an internal balustrade that is easily fixed to the upper part of the embankment. The top balustrade has a certain inclination, which, while meeting the safety requirements of the embankment, allows for the display of cultural and promotional content, enhancing the overall aesthetics of the balustrade. The outer balustrade also has mounting holes for light sources, facilitating the installation of lighting fixtures and providing pleasant illumination at a suitable height at night. Furthermore, the concrete balustrade has a height H1 of 1050mm, which is suitable. Combined with the slight inclination of the top balustrade in the installed state, it provides convenient support for rest and leaning during daily life. Since the outer balustrade is made of translucent concrete, it also enhances the aesthetics. The fiber optic distribution pattern on the outer balustrade can be changed to add unique features. It can also be quickly prefabricated in the factory, shortening the construction cycle. It has the advantages of high reproducibility, high comfort, good aesthetics, and multifunctionality, making up for the shortcomings of traditional guardrails.

[0007] Furthermore, in order to facilitate the secure installation of this guardrail on the embankment, it also includes a first installation structure and a second installation structure. The inner guardrail is fixedly connected to the upper end of the embankment through the first installation structure, and the outer guardrail is fixedly connected to the outer side of the embankment through the second installation structure.

[0008] Furthermore, in order to provide an easy-to-install installation structure, the first installation structure includes a steel plate, a first expansion bolt, a steel keel support, a first L-shaped fastening plate, and a first fastening seat. The first fastening seat is fixed to the inner side of the inner side panel by a first bolt, with the fastening interface of the first fastening seat facing downwards. The steel plate is fixed to the upper end of the embankment by a plurality of first expansion bolts. The steel keel support is vertically fixed to the steel plate. A first angle steel is fixed to one side of the steel keel support. The first angle steel is fixed to the first L-shaped fastening plate by fastening bolts. The first L-shaped fastening plate is fastened and fixed to the first fastening seat.

[0009] The second installation structure includes a second angle steel, a second L-shaped fastening plate, and a second fastening seat. The second fastening seat is fixed to the inner side of the outer railing by a second bolt, with the fastening interface of the second fastening seat facing downward. The second angle steel is fixed to the outer side of the embankment by a second expansion screw. The second L-shaped fastening plate is fixed to the second angle steel by a third bolt, and the second L-shaped fastening plate is fastened and fixed to the second fastening seat.

[0010] Furthermore, to improve the installation effect, a cushion layer is poured on the outer side of the embankment at the lower end of the outer railing, and the cushion layer has an arc that adapts to the arc of the lower end of the outer railing.

[0011] Furthermore, to ensure the sealing effect of the inner side of the guardrail, the lower inner side of the inner guardrail panel is filled with weather-resistant sealing adhesive between itself and the embankment.

[0012] Furthermore, to facilitate the maintenance of the lighting fixtures inside the guardrail, an inspection port is provided on the inner side panel, and a maintenance plate is detachably installed at the inspection port.

[0013] Furthermore, to ensure the structural strength of the guardrail, the thickness of the concrete guardrail panels is 30mm.

[0014] Furthermore, in order to ensure that the top railing has a suitable width and the outer railing has a suitable height, and to improve the comfort of leaning against the railing, the width D of the top railing is 501mm and the length H3 of the outer railing is 740mm.

[0015] The beneficial effects of this utility model are as follows: The internal railing is easily fixed to the upper end of the embankment. The top railing has a certain inclination, which, while meeting the safety requirements of the embankment, allows for the display of cultural and promotional content, enhancing the overall aesthetics of the railing. The outer railing also has light source mounting holes, facilitating the installation of lighting fixtures at suitable heights during nighttime. Furthermore, the concrete railing's height H1 is 1050mm, a suitable height, and combined with the top railing's inclination angle during installation, it provides convenient support for daily rest. Since the outer railing is a translucent concrete railing, it also enhances aesthetics. The optical fiber distribution pattern on the outer railing can be altered to add character. It can also be quickly prefabricated in a factory, shortening the construction cycle. It boasts advantages such as high reproducibility, high comfort, good aesthetics, and multifunctionality, overcoming the shortcomings of traditional guardrails. Attached Figure Description
