济南大型广告牌作为一种传统的广告载体,一直以来,以其经济价廉、设置方便、效果显著等优点,受到广告主的广泛喜爱。为强化其向公众传递信息的功能,济南大型广告牌多设置在高大建筑物的顶部,繁华商业街区,主要交通干线、通道的两侧,以及临街店铺的墙体上。这些位置大多处于或邻近人口稠密的区域,因此,在设置户外广告牌时,对其安全性也提出了更高的要求。
 
Ji'nan large advertising brand as a traditional advertising carrier, has been, with its low cost, easy to set up, the effect is obvious advantages, is widely loved by advertisers. In order to strengthen the function of the transmission of information to the public, Jinan large billboards set at the top of tall buildings, bustling commercial district, on both sides of the main traffic arteries, channel, and street shops of the wall. Most of these locations are in or adjacent to a densely populated area, and therefore, the safety of the set of outdoor advertising is also raised.
 
1.地基失稳原因及加固、纠偏方法
 
1 Foundation instability cause and reinforcement, correction method
 
通常把支撑户外广告牌的承载物称为地基,落地式广告牌以土体或岩体作为地基,又分为人工地基和天然地基;楼宇广告牌与墙面广告牌则以楼顶结构和墙体结构作为地基。对户外广告牌而言,地基的设置至关重要,它直接关系到户外广告牌正常使用。常见的广告牌基础工程事故多由以下原因造成:地基承载力不足导致地基失稳;地基土质过软,长期受负后产生地基倾斜;周边地质环境的改变,导致地基土体膨胀或收缩变形;墙面广告牌的支座松动、损坏;外力因素(包括大风、野蛮施工等)造成的楼宇广告牌的不均匀沉降。
 
Usually the bearing of the support of the outdoor advertising brand known as the foundation, landing type advertising signs to the soil or rock as the foundation, and is divided into artificial foundation and natural foundation; building billboards and wall billboards are based on the roof structure and wall structure as the foundation. For outdoor billboards, the foundation is very important, it is directly related to the normal use of outdoor billboards. Common advertising brand based on the cause of the accident: the foundation bearing capacity of the foundation is weak, the foundation soil is too soft, the foundation is weak, the surrounding geological environment changes, causing the foundation soil swelling or shrinkage deformation; wall advertising signs of a loose, damage; external factors (including wind, wild construction, etc.) caused by the uneven settlement of buildings.
 
基础工程事故的发生主要由于勘察、设计、施工不当或使用环境改变而引起的。出现地基失稳现象之后,应及时对户外广告牌地基础进行加固与纠偏,在确定实施方案之前,应做好以下几项调查工作:(1)查清地基所在区域的土质、水文情况;(2)查阅原始资料,了解广告牌地基形式和受力状态,以及设计承载量;(3)对广告牌施工过程中使用的建筑材料质量、施工期间的天气状况,以及整体广告牌的施工质量进行勘查;(4)调查广告牌使用期间周围环境的变化情况,如市政设施的修建、附近建筑的开工,地下水位的升降和地面排水系统的变化等。
 
The occurrence of basic engineering accidents is caused mainly due to the investigation, design, construction or use of environmental change. After the foundation instability phenomenon, should be promptly on the basis of the outdoor advertising brand reinforcement and rectification, in determining the implementation plan, should do the following survey work: (1) to find out the soil, hydrological situation; (2) access to raw materials, to understand the brand foundation form and load state, and the design load; (3) the construction process of building materials quality, weather conditions, and the overall advertising brand construction quality, such as municipal facilities construction, the construction of the nearby buildings, underground water level and surface drainage system changes, etc..
 
搞清了济南大型广告牌 http://www.xiongdiguanggao.com/ 地基发生失稳的症结所在,就可以在此基础上,制定行之有效的加固与纠偏措施。
 
To find out the crux of the instability of large billboards in Ji'nan, on the basis of this, we can develop effective measures to reinforce and rectify the problem.
 
2.定期检测。在济南大型广告牌投入使用之后,应定期对其安全性进行检查,及时发现并更换受损、老化的构件。若主构件出现较严重的老化或损伤,应考虑采取加固措施。
 
2 periodic detection. After the Ji'nan large advertising signs put into use, should be regularly on its security checks, and timely replacement of damaged, aging components. If the main component of a more serious aging or damage, should consider taking reinforcement measures.
 
注意防腐。最常用的钢材防腐措施有:在钢材表面涂刷油漆,或在构件表面喷镀金属保护层;不同金属接触也会造成腐蚀,若构建中使用了不同金属材料,应对其接触面进行绝缘处理;另外在设计时,还应注意材料的放置,避免钢材凹槽朝上造成积水而引起材质锈蚀。
 
Pay attention to corrosion. The most commonly used steel anti-corrosion measures are: coating on the steel surface, or in the surface of the component metal coating; different metal contact will cause corrosion, if the use of different metal materials, to deal with the contact surface insulation treatment; in addition, should also pay attention to the placement of materials, avoid steel groove face upward caused by material corrosion.
 
当济南大型广告牌钢结构物存在设计缺陷或受外力损伤,影响其牢固性时,应及时对其进行加固。钢结构的加固方法很多,总结起来主要有以下几种:
 
When the Ji'nan large billboard steel structure exists design flaws or by external damage, the impact of its strong, should be timely reinforcement. There are many ways to reinforce the steel structure, and the following are the following:
 
加大受力截面。这种方法广泛用于广告牌支撑物、节点钢板的加固,可提高构件的承载力,但也会增加广告牌自身的重量和造价,在使用上有局限性。
 
Increase the stress section. This method is widely used in the reinforcement of the supporting material and the joints of the plate, which can improve the bearing capacity of the members, but also increase the weight and the cost of the advertising brand.
 
外加预应力拉杆或撑杆。这种方法可提高构件承载力,增大其抗裂性。由于这种方法改变了原整体结构的受力分配,因此实施时应做详细的力学计算。
 
External prestressed rod or pole. This method can improve the bearing capacity of the member, and increase its anti cracking performance. As a result of this method has changed the distribution of the whole structure of the original, so the implementation of the mechanical calculation should be done in detail.
 
增设支点或托架。这种方法可减小构件的承力跨度,降低钢性结构内部的受力负荷,减缓材质的老化与变形。多适用于广告牌的扩建。
 
Additional support or bracket. This method can reduce the bearing capacity of the member, and reduce the load of the steel structure, and slow the aging and deformation of the material. More suitable for advertising brand expansion.
 
增补支点。采用增加支座底板与增补化学膨胀螺栓或种植钢筋数量的办法,可增强广告牌整体结构的稳定性和安全系数。
 
Supplementary fulcrum. The stability and safety factor of the whole structure of the advertising brand can be enhanced by increasing the number of the supporting plate and the chemical expansion bolt or the growing number of steel.
 
灌浆法修补裂缝。使用压送设备将化学浆液灌入结构裂缝进行修补。灌入的化学浆液能修复混凝土裂缝,防锈补强,提高构件的整体耐久性。通常使用在广告牌地基与联接钢板之间的加固中。
 
Grouting repair cracks. The chemical grouting is used to repair the structural cracks. The chemical grout can repair the crack of concrete, improve the anti rust, and improve the overall durability of the components. Usually used in the reinforcement of the foundation and the connecting plate.
 
粘结剂加固法。这是一种把钢板粘贴在构件外部的加固方法。具有操作简便,施工周期短,占用空间小,几乎不改变构件外形等优点。通常用于楼宇广告牌支座的承载加固。
 
Bonding method. This is a strengthening method that the steel plate is stuck in the component. Has the advantages of simple operation, short construction period, small footprint, and almost no change in the shape of the component. Usually used in the building of the bearing of the bearing reinforcement.
