The Fire Door Manufacturer Shall Also Make Adhesive On The Back Of The Plate

The fire door manufacturer can only install the prefabricated plate after it reaches the predetermined strength. The prefabricated plate can be divided into thick type and thin type, and the thickness of thick type is; The dimension of thin thickness precast slab is generally long filling, and the fixing method of each precast slab finish is the same as that of marble decoration. Usually, iron parts are embedded in the wall first, then the reinforcement mesh is bound, and then fixed firmly with the reinforcement mesh through the lead wire swing head embedded behind the precast slab, leaving left and right gaps with the wall: back seam. The fixing of block material is the same as that of stone wall, which is generally fixed by fishing or money. Holes and grooves are reserved on the upper and lower sides of the block for fixing iron parts and connecting up and down blocks.

Both sides of the block are made into daily lines, which can make the wall show soft block joints after installation: the actual joint gas of the block is about the thousand hanging of granite plates on the outer wall. The French fixed dry hanging method is to support the plates with stainless steel profiles or connectors and fix them on the wall each other: fix the connectors on the wall with expansion bolts: the spacing between the upper and lower layers is equal to the height of the plates, The groove on the plate of the fire door manufacturer shall be hung on the plate sharing line. Compared with the wet hanging method, the dry hanging method has the following advantages: there is no cement mortar in the cavity formed between the stone plate and the wall: it avoids the serious problems such as flower inspection discoloration and rust on the surface of the facing stone plate caused by the chemical action of cement, As well as problems such as hollowing and crack falling off due to poor hanging and pasting, the facing stone slab is hung on the wall separately, and the quality of each stone will not be transmitted to other stone slabs: there is no cement mortar quality: the wall load or light dry hanging method has fast construction progress: the cycle is short, and the pollution of the site and the labor cost of cleaning the site are reduced. The hanging parts are light and flexible, It can be adjusted up, down, left and right. The decoration quality is easy to ensure. The dry hanging method has the following disadvantages: the cost is high, and the decoration area of the outer wall is operated by skilled technicians. For some walls or columns with complex geometric shapes, Construction comparison: the national difficult dry hanging method is only applicable to reinforced concrete walls: it is not applicable to sintered sound brick walls and aerated concrete block walls. When installing the dry hanging method: first, drill holes on the wall according to the position of stainless steel shadow green bolt according to the specific design. The hole diameter is: hole depth (subject to photo bolt), and the horizontal and vertical spacing can be seen in the design drawing.

After the hole is drilled: please apply the stainless steel green bolt "Make great efforts to install people in the cave: tighten and tighten, and then at the length of each plate from the top and bottom edges of the facing stone plate to both sides: living in the plate: one standard opening for each deep opening, for loose stone: the fire door manufacturer also needs to make adhesive on the back of the plate: paste glass fiber mesh fabric reinforcement: and give a certain curing time: during this period, prevent moisture and close the stainless steel angle steel pendant When installed in × On the stainless steel tension bolt (do not tighten the nut) : then temporarily fix the stainless steel plate pendant on the stainless steel angle steel pendant with the stainless steel green bolt. The plate installation sequence is carried out layer by layer from bottom to top. According to the selected finishing stone plate number, temporarily put the stone plate in place: insert the stainless steel plate pin into the stone plate hole: adjust the accuracy, perpendicularity and flatness of the stone plate position by using the adjustment holes on the angle steel pendant and the plate pendant The stem thread connection shall be firm and reliable. After the plate is assembled and connected with the supporting steel plate, a layer of "Dali" shall be painted on the contact between the bolt and the hanger and the pin hole (the decorative stone plate wall decorated by the dry hanging method construction process of fast drying type, and the plate joint shall be determined according to the thickness of the hanger.
