钢筋网片是怎么固定在墙上的?

添加时间:2019-07-05      发布人:

  钢网片在墙体上可以起到一定的维护作用,很多行业都会在自己的墙体上安装钢网片。但是,钢网片的固定操作比较复杂,如果想把这个固定好,就必须掌握正确的方法。那么如何将钢网固定在墙上呢?
  Steel mesh can play a certain role in the maintenance of the wall, many industries will install steel mesh on their own walls. However, the fixing operation of steel mesh is rather complicated, if you want to fix this well, you must master the correct method. So how to fix the steel mesh on the wall?
  电焊钢网片水泥表面加固方法:可大大提高砖墙的承重经验、抗弯刚度和延性,改变其固有振动频率,使正常使用阶段的功能有一定的提高;施工工艺简单、适用,加固后砌体承载力大大提高,具有良好的效果和施工经验的前提。适用于无裂缝的实心砖墙,主要用于剪力墙、有孔空心砖墙(孔径半大于15mm)、厚度240mm的空心砖墙。
  Welded steel mesh cement surface reinforcement method: can greatly improve the bearing experience, flexural rigidity and ductility of brick wall, change its natural vibration frequency, and improve the function of normal use stage to a certain extent; construction technology is simple and applicable, and the bearing capacity of masonry is greatly improved after reinforcement, which is the premise of good effect and construction experience. It is suitable for solid brick walls without cracks. It is mainly used for shear walls, hollow brick walls with holes (aperture is more than 15 mm), and hollow brick walls with thickness of 240 mm.
  电焊钢板外粘接加固方法:该方法属于传统的加固方法,是一种用粘接剂将钢板粘接在墙体裂缝部位的加固方法。常用胶粘剂主要是环氧气体天然树脂。这种方法的优点是施工简单快速,大量的现场工作和湿工作较少,对生产和生活的影响很小,根本不改变组件的形状和空间的使用,但可以大大增加墙的抗剪能力和正常使用阶段功能、力量更可靠;适用于砌体加固,既不允许增加原构件的型材尺寸,又要求较大的波动以提高型材的承载力。
  Welded steel plate external bonding reinforcement method: This method belongs to the traditional reinforcement method, is a kind of reinforcement method which uses bonding agent to bond steel plate to the cracks in the wall. The common adhesives are natural epoxy resin. The advantages of this method are simple and fast construction, less on-site work and wet work, little impact on production and life, no change in the shape of components and space use, but it can greatly increase the shear capacity of walls and the function and strength of normal use stage is more reliable; it is suitable for masonry reinforcement, and it is not allowed to increase the original structure. In order to improve the bearing capacity of profiles, the size of profiles should fluctuate greatly.
  电焊钢筋网预应力加固法:采用体外预应力钢拉杆(分水平拉杆、底部拉杆、组合拉杆或拉杆)加固结构的方法。该方法可以降低加固构件的应力水平,提高墙体正截面和斜截面的承载力。预应力可以消除或减小后加构件的应力滞后,使后加构件有效地工作。
  Welded steel mesh prestressing reinforcement method: External prestressing steel tie rod (horizontal tie rod, bottom tie rod, combined tie rod or tie rod) is used to reinforce the structure. This method can reduce the stress level of reinforced members and improve the bearing capacity of normal and oblique sections of walls. Prestressing can eliminate or reduce the stress lag of the post-added component, and make the post-added component work effectively.

  预应力萌发负弯矩可以消除部分荷载弯矩,减小墙体的外倾角,增大和减小墙体的裂缝宽度,甚至可以闭合墙体中的裂缝。该方法的优点是可以大大提高砌体柱的承载力,加固效果可靠,适用于高应力、高应变砌体结构的加固。
  Negative moment of pre-stressed germination can eliminate partial load moment, reduce the inclination angle of wall, increase and reduce the crack width of wall, and even close cracks in wall. The advantages of this method are that the bearing capacity of masonry columns can be greatly improved, the reinforcement effect is reliable, and it is suitable for the reinforcement of masonry structures with high stress and strain.
  加强电焊网钢板法:碳纤维布的抗剪能力严重受损的墙由碳纤维布增强的计算严重受损的砌体墙的抗剪承载力得到了碳纤维布后注入结构胶(修补裂缝)和严重损坏墙的抗剪承载力提高系数由于注入结构胶关节。计算图和承载力增加系数可用于估算碳纤维布加固严重破坏墙体的抗剪承载力。一般来说,钢板固定操作并不十分困难,只要我们能按照上述基本方法固定钢板就可以了。
  Strengthen Welded Wire Mesh Steel Plate Method: Calculate the shear capacity of severely damaged walls strengthened by carbon fiber sheet. The shear capacity of severely damaged masonry walls is improved by injecting structural glue (repairing cracks) after carbon fiber sheet, and the shear capacity of severely damaged walls is increased by injecting structural glue joints. The calculation diagram and load-increasing coefficient can be used to estimate the shear capacity of the wall strengthened with CFRP. Generally speaking, it is not very difficult to fix the steel plate, as long as we can fix the steel plate according to the basic method mentioned above.
