当济南大型广告牌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 large billboards in Ji'nan exist design flaws or damaged by the external force, when the impact of its firmness, should be promptly reinforced。 There are many ways of strengthening the steel structure, and there are mainly the following several:

1、加大受力截面。这种方法广泛用于济南大型广告牌 http://www.gift4yu.com/盛京棋牌 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。

1, increasing the force cross section. This method widely used in Jinan large billboards support and reinforcement of the steel plate joints, improve the component bearing capacity, but also increase the Billboard's own weight and cost, in use have limitations.

2、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。

2, external prestressed rod or pole。 This method can improve the bearing capacity of the member, and increase its anti cracking property。。 Because this method changed the distribution of the whole structure, the mechanical calculation should be done in detail。。

3、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。

3, additional fulcrum or bracket. This method can reduce the load span of the member, reduce the load of the steel structure, and slow the aging and deformation of the material.. Expansion of advertising brand.

4、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。

4, supplementary fulcrum。 The stability and safety factor of the whole structure of the billboard can be enhanced by using the method of increasing the number of the chemical expansion bolts and the chemical expansion bolts or the reinforcement。。

5、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。

5, grouting repair cracks。 The chemical grout was used to repair the structural cracks by using the pressure equipment。。 The chemical grout can repair the cracks of concrete, rust preventive and improve the overall durability of the component。。 The reinforcement between the foundation and the connecting plate is usually used in the advertising。。

6、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。通常用于济南大型广告牌的承载加固。

6, bonding reinforcement method。 This is a reinforcement method that is externally bonded to the member。 Has the advantages of simple operation, short construction period, small footprint, and almost no change of the shape of the component。。 The load and reinforcement of the large billboard in Ji'nan is commonly used。
