鋼網(wǎng)片在墻體上可以起到一定的維護(hù)作用,很多行業(yè)都會(huì)在自己的墻體上安裝鋼網(wǎng)片。但是,鋼網(wǎng)片的固定操作比較復(fù)雜,如果想把這個(gè)固定好,就必須掌握正確的方法。那么如何將鋼網(wǎng)固定在墻上呢?
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?
電焊鋼網(wǎng)片水泥表面加固方法:可大大提高磚墻的承重經(jīng)驗(yàn)、抗彎剛度和延性,改變其固有振動(dòng)頻率,使正常使用階段的功能有一定的提高;施工工藝簡單、適用,加固后砌體承載力大大提高,具有良好的效果和施工經(jīng)驗(yàn)的前提。適用于無裂縫的實(shí)心磚墻,主要用于剪力墻、有孔空心磚墻(孔徑半大于15mm)、厚度240mm的空心磚墻。
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.
電焊鋼板外粘接加固方法:該方法屬于傳統(tǒng)的加固方法,是一種用粘接劑將鋼板粘接在墻體裂縫部位的加固方法。常用膠粘劑主要是環(huán)氧氣體天然樹脂。這種方法的優(yōu)點(diǎn)是施工簡單快速,大量的現(xiàn)場工作和濕工作較少,對(duì)生產(chǎn)和生活的影響很小,根本不改變組件的形狀和空間的使用,但可以大大增加墻的抗剪能力和正常使用階段功能、力量更可靠;適用于砌體加固,既不允許增加原構(gòu)件的型材尺寸,又要求較大的波動(dòng)以提高型材的承載力。
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.
電焊鋼筋網(wǎng)預(yù)應(yīng)力加固法:采用體外預(yù)應(yīng)力鋼拉桿(分水平拉桿、底部拉桿、組合拉桿或拉桿)加固結(jié)構(gòu)的方法。該方法可以降低加固構(gòu)件的應(yīng)力水平,提高墻體正截面和斜截面的承載力。預(yù)應(yīng)力可以或減小后加構(gòu)件的應(yīng)力滯后,使后加構(gòu)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.
預(yù)應(yīng)力萌發(fā)負(fù)彎矩可以部分荷載彎矩,減小墻體的外傾角,增大和減小墻體的裂縫寬度,甚可以閉合墻體中的裂縫。該方法的優(yōu)點(diǎn)是可以大大提高砌體柱的承載力,加固效果可靠,適用于高應(yīng)力、高應(yīng)變砌體結(jié)構(gòu)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.
加強(qiáng)電焊網(wǎng)鋼板法:碳纖維布的抗剪能力嚴(yán)重受損的墻由碳纖維布增強(qiáng)的計(jì)算嚴(yán)重受損的砌體墻的抗剪承載力得到了碳纖維布后注入結(jié)構(gòu)膠(修補(bǔ)裂縫)和嚴(yán)重?fù)p壞墻的抗剪承載力提高系數(shù)由于注入結(jié)構(gòu)膠關(guān)節(jié)。計(jì)算圖和承載力增加系數(shù)可用于估算碳纖維布加固嚴(yán)重破壞墻體的抗剪承載力。一般來說,鋼板固定操作并不十分困難,只要我們能按照上述基本方法固定鋼板就可以了。
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.
