The difference between penetrating and concealed color steel plate roofing

Calculate purlins. There is a difference at the time.

The penetration is connected with the purlin by self-tapping nails, which can constrain the upper flange of the purlin, which is beneficial to the overall stability.

The concealed buckle is a buckle, which cannot restrain the upper flange of the purlin.

Generally speaking, there are two main ways to fix the color steel plate: penetration and concealment.

Penetrating fixed type is a commonly used installation method, at present the main use is a kind of self-tapping screw or rivet to fix the color plate on the support (such as purlin), and the penetrating type fixing is divided into crest fixing, trough fixing or their combination. And the concealed fixing of the concealed buckle is to fix the special concealed buckle matched with the concealed buckle color plate on the support (such as purlin), and the female rib of the color plate and the central rib of the concealed buckle are toothed together in the fixing method, and this fixing method is generally mainly used in the installation of the roof.

Color steel plate refers to the color coated steel plate, which is a kind of steel plate with organic coating. Color steel plates are divided into veneer, color steel composite plates, floor deck plates, etc. It is widely used in the walls and roofs of large public buildings, public workshops, prefabricated houses, and integrated houses.

The substrate of color steel plate is cold-rolled substrate, hot-dip galvanized substrate and electro-galvanized substrate. The types of coatings can be divided into polyester, silicone-modified polyester, polyvinylidene fluoride and plastisol. The surface state of color steel plate can be divided into coated plate, embossed plate and printing plate, color steel plate is widely used in building appliances and transportation and other industries, for the construction industry is mainly used for steel structure workshops, airports, warehouses and refrigeration and other industrial and commercial buildings such as roofs, walls and doors, etc., civil buildings use less color steel plates.

There are two kinds of fixing methods for the installation of the color steel tile press, which are penetrating and concealed. Penetrating fixing is the most common way to install the color steel tile press on the roof and wall, that is, to fix the color plate on the support with self-tapping screws or rivets.

Penetrating fixing is the most common way to install color steel equipment on roofs and walls, that is, using self-tapping screws or rivets to fix the color plate on the supports, and penetrating fixing is divided into crest fixing, trough fixing or their combination. The installation method of the concealed buckle type (concealed type) is a little more cumbersome, the concealed fixing of the concealed buckle is to fix the special concealed buckle matched with the concealed buckle color plate on the support piece first, the fixing method of the mother rib of the color plate and the central rib of the concealed buckle is generally used for the installation of the roof panel, before installing the next steel plate, each steel plate must be completely fixed, and the fixing must start from the center of the steel plate, then stretch to both sides, and finally fix the lap edge of the steel plate.

This can be dismantled and repaired, but to find the same model of the same size of the color steel plate, and dismantle and repair, the area may be larger.

It's better to redo it if you need to.

The concealed high-strength color steel plate roof is to fix the special concealed fastener matched with the concealed button color plate on the support first, and use the mother rib of the color steel plate to mesh with the central rib of the concealed buckle to fix, changing the previous practice of using self-tapping screws or rivets to penetrate and directly fix the color steel plate on the support, this unique fixing method is more intuitive and can resist typhoon more effectively, and avoid damage to the color steel plate from the process, and make the color steel plate can expand and contract freely when subject to temperature changes, reduce the overall deformation of the roof, So as to ensure that the roof system achieves a better waterproofing effect.

I'm a color steel maker, so I don't understand what you want to ask? You should be talking about the glass wool on-site composite situation. There are two ways:

1.The upper and lower color steel plates plus glass wool on-site composite 2The bottom plate is steel wire, and the upper part is a color steel plate, and glass wool is sandwiched in the middle.

It should be what you said about hiding and exposure, because the second type of steel wire mesh can see glass wool, glass wool has double aluminum foil and single aluminum foil.

For the purlin exposed type, the double-layer color steel plate is usually provided with thermal insulation materials, so the role of the lower steel plate at this time is mainly to support the thermal insulation materials, and it has the effect of beautiful ceiling. For the hidden type, one is to support the internal thermal insulation material, and the other is to play the role of out-of-plane support when the lower flange of the purlin is compressed.

I am a ******** of Yichang Zhehao dry Zheng Xiao steel knot, according to your question, as follows:

According to the type of dark buckle, with a good degree of support, such as 820 type, 760 type, for the angle of the third type, 470, 475 for the angle of the second type.

The first defeat is on the purlin repentance, with the way of pulling the wire, to determine the position of the bracket, and then fix the bracket with self-tapping nails, and then put the hidden buckle color steel tile in the bracket, and finally use the manual or electric undercut machine to bite the edge, it is OK, the whole back to the roof can not see the nail, this kind of special anti-typhoon, rain-proof, no rain leakage.
