Summary of the invention
[0004] In order to solve the problems in the prior art that rock wool insulation boards without outer protective walls are difficult to fix on structural walls and the construction of outer wall rock wool insulation systems is difficult, the present invention provides a construction method for dry-hanging rock wool insulation on inclined curtain walls. This construction method can construct an outer wall rock wool insulation system without outer protective wall construction, is convenient for fixing the rock wool insulation boards, and has convenient and efficient construction.
[0005] In order to achieve the above object, the technical solution of the present invention is: a method for dry hanging rock wool insulation of an inclined curtain wall, comprising the following steps: Step 1: Arrange support frames at intervals on each vertical keel of the curtain wall keel, and the support frames include two plain round steel bars symmetrically installed on both sides of the vertical keel. The plain round steel bars of the support frame play a supporting and limiting role for the hydrophobic rock wool insulation board.
[0006] Step 2: Install a U-shaped bracket on each layer of the curtain wall keel support frame. The U-shaped bracket is fixedly installed on the inner side of the vertical keel. The U-shaped bracket supports the hydrophobic rock wool insulation board to prevent the hydrophobic rock wool insulation board from falling.
[0007] Step 3: After the U-shaped bracket is installed, install the wire mesh on the inner side of the curtain wall keel. The wire mesh is hung on the end of the plain round steel bar. The reserved gap between the wire mesh and the curtain wall keel is the installation space for the rock wool insulation board. The wire mesh can be used to limit the rock wool insulation board to prevent it from falling and tipping over.
[0008] Step 4: Select a rock wool insulation board of corresponding size according to the distance between two adjacent vertical keels and two adjacent support frames, and the thickness of the rock wool insulation board should match the reserved gap between the wire mesh and the curtain wall keel; the rock wool insulation board should be a hydrophobic rock wool insulation board.
[0009] Step 5: Cover the surface of the hydrophobic rock wool insulation board with aluminum foil, and then insert the hydrophobic rock wool insulation board into the reserved gap between the steel mesh and the curtain wall keel. Through the cooperation of the curtain wall keel, the steel mesh and the support frame, the hydrophobic rock wool insulation board is fixed and the insulation construction is realized.
[0010] Step 6: Paste a waterproof and breathable membrane on the outside of the hydrophobic rock wool insulation board for waterproofing. The waterproof and breathable membrane can enhance the overall waterproof performance of the curtain wall.

[0012] Furthermore, in step 1, the distance between two adjacent support frames on each vertical keel is 600 mm, and the distance between two plain round steel bars of the support frame is the thickness of the vertical keel.
[0013] Furthermore, in step 1, the plain round steel bar is hot-dip galvanized before being fixed to the vertical keel. The plain round steel bar includes a horizontal portion and an inclined portion. The horizontal portion of the plain round steel bar is welded and fixed to the vertical keel. The purpose of the hot-dip galvanizing of the plain round steel bar is to prevent it from rusting and affecting the service life of the plain round steel bar.
[0014] Furthermore, in step 1, after the plain round steel bars are welded and fixed on the vertical keel, anti-rust and anti-corrosion treatment is performed on the welding points between the plain round steel bars and the vertical keel, and anti-rust paint is applied on the welding points between the plain round steel bars and the vertical keel. The purpose of the anti-rust and anti-corrosion treatment is to ensure the strength and stability of the welding parts and extend the service life of the welding parts.
[0015] Furthermore, in step 3, the wire mesh is hung on the end of the plain round steel bar by using the cooperation of the U-shaped clip and the bolt, and the wire mesh is fixed to the plain round steel bar by the U-shaped clip, so that the wire mesh plays a role of limiting and fixing the hydrophobic rock wool insulation board.
[0016] Furthermore, in step 6, an adhesive is applied to the outside of the hydrophobic rock wool insulation board, and the waterproof breathable membrane is fixed to the outside of the hydrophobic rock wool insulation board by the adhesive, and the waterproof breathable membrane is fixed to the hydrophobic rock wool insulation board by the adhesive to form an integral waterproof membrane on its outside.
[0017] Through the above technical solution, the beneficial effects of the present invention are: The present invention solves the problem that the rock wool insulation board without an outer protective wall is difficult to fix on the structural wall and the construction of the outer wall rock wool insulation system is difficult. The invention can be constructed without the help of an outer protective structure and does not affect the indoor construction. The insulation construction is realized by the curtain wall keel, which is convenient for fixing the rock wool insulation board. The construction is convenient and efficient, and a complete outer wall rock wool insulation system can be formed to meet the energy-saving requirements. At the same time, it can also be widely used in the construction of inclined outer curtain wall insulation systems, eliminating the inclined outer protective wall, shortening the construction period, and meeting the energy-saving requirements.
[0018] The present invention welds and fixes plain round steel bars on the vertical keel of the curtain wall keel, uses the plain round steel bars to support and limit the rock wool insulation board, and simultaneously supports the hydrophobic rock wool insulation board through a U-shaped bracket to prevent the rock wool insulation board from falling; and limits the rock wool insulation board through a steel wire mesh to prevent the rock wool insulation board from falling and tipping over; the purpose of fixing the rock wool insulation board is achieved through the cooperation of the curtain wall keel, the steel wire mesh and the supporting frame, and the effect of constructing a complete exterior wall rock wool insulation system through insulation construction is realized.

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments: like Figures 1 to 9 As shown, a method for dry hanging rock wool insulation on an inclined curtain wall comprises the following steps: Step 1: Support frames are arranged at intervals on each vertical keel 1 of the curtain wall keel, and the support frames on two adjacent vertical keels 1 are located in the same horizontal plane. In this embodiment, the curtain wall keel is arranged at an angle, and an effective fixed fulcrum for the hydrophobic rock wool insulation board 6 is provided through the curtain wall keel. The support frame includes two smooth round steel bars 2 symmetrically installed on both sides of the vertical keel 1, and the smooth round steel bars 2 are A6 smooth round steel bars; the spacing between two adjacent support frames on each vertical keel 1 is 600mm, and the spacing between the two smooth round steel bars 2 of the support frame is the thickness of the vertical keel 1. The smooth round steel bars of the support frame support and limit the hydrophobic rock wool insulation board 6, and the hydrophobic rock wool insulation board 6 is subjected to force by the smooth round steel bars 2.
[0022] The plain round steel bar 2 is hot-dip galvanized before being fixed to the vertical keel 1. The purpose of the hot-dip galvanizing of the plain round steel bar 2 is to prevent it from rusting and affecting the service life of the plain round steel bar 2. The plain round steel bar 2 includes a horizontal portion and an inclined portion. The horizontal portion of the plain round steel bar 2 is welded and fixed on the vertical keel 1, wherein the inclined portion of the plain round steel bar 2 not only limits the hydrophobic rock wool insulation board 6, but also effectively prevents the hanging wire mesh 4 from falling. After the plain round steel bar 2 is welded and fixed on the vertical keel 1, the welding point between the plain round steel bar 2 and the vertical keel 1 is treated with anti-rust and anti-corrosion, and anti-rust paint is applied to the welding point between the plain round steel bar 2 and the vertical keel 1, the purpose of which is to ensure the strength and stability of the welding part of the two and extend the service life of the welding part.
[0023] Step 2: Install a U-shaped bracket 3 on each layer of the curtain wall keel support frame. The U-shaped bracket 3 is fixedly installed on the inner side of the vertical keel 1. The U-shaped bracket 3 adopts a 5mm thick U-shaped galvanized steel plate bracket, which supports the hydrophobic rock wool insulation board 6 to prevent the hydrophobic rock wool insulation board 6 from falling. The U-shaped bracket 3 can be welded and fixed to the vertical keel 1 or bolted to the vertical keel 1.
[0024] Step 3: After the U-shaped bracket 3 is installed, install the steel mesh 4 on the inner side of the curtain wall keel. The steel mesh 4 is hung on the end of the plain round steel bar 2. The reserved gap between the steel mesh 4 and the curtain wall keel is the installation space of the rock wool insulation board. The steel mesh 4 limits the rock wool insulation board to prevent it from falling and tipping over. The steel mesh 4 is made of A3 50*50 hot-dip galvanized steel mesh. The steel mesh 4 is hung on the end of the plain round steel bar 2 by using the U-shaped buckle 5 and the bolt. The U-shaped buckle 5 is made of metal.

The purpose of using the hydrophobic rock wool insulation board 6 is to solve the problem of the rock wool insulation board absorbing water and increasing its own gravity load.
[0026] Step 5: The surface of the hydrophobic rock wool insulation board 6 is covered with aluminum foil, and then the hydrophobic rock wool insulation board 6 is stuffed into the reserved gap between the wire mesh 4 and the curtain wall keel. The purpose of covering the surface of the hydrophobic rock wool insulation board 6 with aluminum foil is to ensure the cleanliness of the indoor environment and prevent the rock wool fibers from being inhaled into the human lungs, causing personal injury.
[0027] Step 6: Paste the waterproof breathable membrane 7 on the outside of the hydrophobic rock wool insulation board 6 for waterproof treatment; apply adhesive on the outside of the hydrophobic rock wool insulation board 6, and use the adhesive to fix the waterproof breathable membrane 7 on the outside of the hydrophobic rock wool insulation board 6. The waterproof breathable membrane 7 forms an overall waterproof membrane on the outside of the hydrophobic rock wool insulation board to enhance the overall waterproof performance of the curtain wall.
[0028] Step 7: Repeat steps 5 and 6 above until a complete exterior wall rock wool insulation system is constructed.
