景观护栏是城市中常见的一种景观护栏,它是用来保障人和车辆行驶安全、防止坠落或冲撞的一种必不可少的安全措施,也是和行人比较靠近的部分,景观护栏的造型设计会直接影响到桥梁的美观。 景观护栏样式丰富,主要分为四个类型,栅栏式、栏板式、棂格式和混合式。在设计景观护栏的时候,应该主要注意一下两点:
Landscape guardrail is one of the most common landscape guardrails in the city. It is an essential safety measure to ensure the driving safety of people and vehicles and prevent falling or collision. It is also a part close to pedestrians. The shape design of landscape guardrail will directly affect the beauty of the bridge. Landscape guardrail style is rich, mainly divided into four types, fence type, fence board, lattice format and mixed type. In the design of landscape fence, we should pay attention to the following two points:
一、景观护栏的尺度。这是非常重要的一点,因为栏杆的最主要的作用就是保证人车的安全,如果没有安全感,自然也谈不上美感,所以这就要求景观护栏必须足够结实,经得起拥挤和冲撞,给人们带来安全感和可依赖感。
1、 The scale of landscape fence. This is a very important point, because the most important role of railings is to ensure the safety of people and vehicles. If there is no sense of security, there will be no sense of beauty. Therefore, this requires that the landscape fence must be strong enough to withstand congestion and collision, and bring a sense of security and dependability to people.
还有一点,栏杆的高度不能过高而阻碍人们的视野,栏杆的高度可以根据桥面出水距离而定,一般净空距离三米以上时,栏杆手扶面约为一米,当净空距离小于三米时,可适当减低栏杆高度。
Another point is that the height of the railing should not be too high to hinder people's vision. The height of the railing can be determined according to the water outlet distance of the bridge deck. Generally, when the clearance distance is more than three meters, the hand support surface of the railing is about one meter. When the clearance distance is less than three meters, the height of the railing can be appropriately reduced.
对于比较宽的桥面,具有分割带多车道桥梁,栏杆的高度和端面尺寸可以略大些,以增加景观护栏的稳重感。
For a wide bridge deck, the height and end face size of railings can be slightly larger to increase the sense of stability of landscape guardrails.
二、样式的多样与统一。现在景观护栏的设计多以简洁明快的格调为主,但是在栏杆的构成部件的图案造型还是可以灵活多变的,这样既可以避免单调乏味,又可以保持栏杆的和谐统一,不影响桥梁的主体。
2、 The diversity and unity of styles. At present, the design of landscape guardrail is mainly based on simple and lively style, but the pattern modeling of the components of the railing can be flexible and changeable, which can not only avoid monotony, but also maintain the harmony and unity of the railing, without affecting the main body of the bridge.
