DETAILED DESCRIPTION

[0034] The technical solution in the embodiment of the present application is to solve the problem in the related art that the installation steps of the right-angle steel columns are cumbersome and affect the curtain wall installation construction period. The overall idea is as follows:

[0035] Example 1:

[0036] This application aims to overcome the shortcomings of related technologies in which the installation steps of right-angle steel columns are cumbersome and affect the curtain wall installation construction period. The overall idea is as follows:

[0037] See also Figure 1-Figure 4A double-layer glass curtain wall structure is installed using a steel support structure, including a plurality of right-angle steel columns 1 connected to the floor concrete embedded parts. The right-angle steel columns 1 are 180*80 steel columns with a cross section such as Figure 1 As shown, and the right-angle steel beam 2 located between adjacent right-angle steel columns 1, the cross section is as shown Figure 1 As shown, the right-angle steel beam 2 is a 120*80 steel beam, and double-layer insulating glass 3 is installed between the right-angle steel column 1 and the right-angle steel beam 2. The double-layer insulating glass 3 is 12+12A+12 insulating glass. Rectangular notches 11 are opened on both side walls of the right-angle steel column 1 at the position where the right-angle steel beam 2 is installed. Each rectangular notch 11 is connected to a clip 4. The horizontally adjacent clips 4 are elastically inserted into the ends of the right-angle steel beam 2 to position it. The right-angle steel column 1 has a sleeve 5 inserted into the inner end of the clip 4. The right-angle steel column 1 uses the combination of the clip 4 and the right-angle steel column 1 to quickly fix the right-angle steel beam 2 between adjacent right-angle steel columns 1. After the sleeve 5 is inserted, the position of the clip 4 can be kept stable.

[0038] The height of the sleeve core 5 is higher than the height of the right-angle steel column 1, and is used for the insertion of the upper right-angle steel column 1. In this way, the upper right-angle steel column 1 can also be inserted outside the lower sleeve core 5, so that the upper and lower adjacent right-angle steel columns 1 can be stably docked.

[0039] The clamping parts 4 each include two slide rails 41 and a block 42 that slides inside the two rails. The two slide rails 41 are fixed on the two opposite inner walls of the rectangular slot 11, and the outer ends are flush with the outer surface of the right-angle steel column 1. The opposite sides are provided with slots, such as Figure 3 As shown, the clamping block 42 is designed in a cross shape, and springs 43 are fixed between its two ends and the notches on the slide plate 41. When installing the right-angle steel beam 2, press the clamping blocks 42 on both sides to move them toward the inside of the rectangular notches 11 until the clamping blocks 42 are flush with the outer surface of the right-angle steel column 1. Take one right-angle steel beam 2 and push it toward the position between the adjacent right-angle steel columns 1. When the two ends of the right-angle steel beam 2 are aligned with the corresponding rectangular notches 11, the springs 43 release the pressure, driving the clamping blocks 42 to insert into the right-angle steel beam 2 and secure it.

[0040] The upper surface of the inner end of the block 42 is designed to be inclined. If the block 42 does not pop out to the appropriate position, insert the sleeve 5 from top to bottom, squeeze the block 42 outward, and insert it into the right-angle steel column 1 to maintain the position of the block 42, thereby increasing the stability of the installation of the right-angle steel beam 2.

[0041] The outer surfaces of the right-angle steel columns 1 and 1 are coated with a silicone structural adhesive layer 6 that adheres to the back of the double-layer insulating glass 3. The silicone structural adhesive layer 6 is a high-performance silicone structural adhesive with a neutral curing property, specially designed for structural bonding and assembly in building curtain walls. It facilitates the connection and fixation of the right-angle steel columns 1 and 1 to the double-layer insulating glass 3.

[0042] A pressure plate 7 is installed between adjacent double-layer insulating glass panels 3. Bolts 8 are mounted on the pressure plate 7, capable of passing through the gap between the adjacent double-layer insulating glass panels 3. Screw holes 12 for tightening the bolts 8 are provided in the right-angle steel column 1. The pressure plate 7 is assembled to the outer surface of the right-angle steel column 1 by fitting the bolts 8 into the screw holes 12, ensuring that the pressure plate 7 is pressed against the adjacent double-layer insulating glass panels 3.

[0043] It should be noted that, Figure 4 As shown, the bolt member 8 includes a small screw rod adapted to the pressure plate 7 and a large screw rod adapted to the right-angle steel column 1, and a nut screwed on the outer end of the small screw rod. The outer end of the large screw rod is hollow in design, and the small screw rod and the hollow part of the large screw rod are welded and fixed. The external thread of the large screw rod is tightened and fixed with the screw hole 12 corresponding to the right-angle steel column 1. The small screw rod is inserted into the preset hole position of the pressure plate 7, and the thread of the outer end of the small screw rod is tightened with the nut to complete the stable installation of the pressure plate 7 and the right-angle steel column 1, that is, the compression of two adjacent double-layer insulating glass 3 can be achieved.

[0044] Silicone weather-resistant sealant 9 is adhered to both sides of the pressure plate 7, tightly attached to the double-layer insulating glass 3. Silicone weather-resistant sealant 9 is a general term for silicone sealants used to seal joints between curtain wall panels. It improves the seal between the pressure plate 7 and the double-layer insulating glass 3, thereby increasing the stability of the installation between the double-layer insulating glass 3 and the steel support structure, and reducing the possibility of gas intrusion into the double-layer insulating glass 3 during long-term use.

[0045] At the same time Figure 1 As shown, the inner outer wall of the pressing plate 7 is also adhered with sealant that is tightly attached to the opposite ends of two adjacent double-layer insulating glasses 3, further improving the sealing performance of the double-layer insulating glasses 3.

[0046] There are slots on both sides of the pressure plate 7, through which the exposed frame buckle covers 10 are slid. The exposed frame buckle covers 10 that slide into the slots on both sides of the pressure plate 7 not only cover the pressure plate 7, improving the overall aesthetics of the curtain wall structure, but also mainly cover the bolts 8, reducing the probability of the bolts 8 rusting and loosening due to long-term wind and rain, indirectly improving the overall stability of the curtain wall structure.

[0047] In a second aspect, the present application further provides a method for installing a double-layer glass curtain wall structure using a steel support structure, comprising the above-mentioned structure for installing a double-layer glass curtain wall using a steel support structure, and the following installation steps:

[0048] S1. Measure and lay out the lines, using a level and a tape measure as tools to draw out the elevation lines of each floor to determine the locations where the right-angle steel columns 1 and right-angle steel beams 2 need to be installed.

[0049] S2. Install the embedded parts. Determine the position of the embedded parts according to the elevation line in step S1 and use chemical bolts to install the embedded parts in the concrete part corresponding to the floor. The embedded parts are used to assist in the later installation of the right-angle steel column 1.

[0050] S3. Install the right-angle steel column 1, mark the installation position of the right-angle steel column 1 on each embedded part, weld the angle code to the embedded part, and then fix the angle code to the side wall of the right-angle steel column 1 to fix the right-angle steel column 1 to the embedded part.

[0051] The angle brackets in step S3 are fixed to the side wall of the right-angle steel column 1 by welding. This changes the method of using bolts to install the angle brackets on the right-angle steel column 1 during the relevant curtain wall installation process. This installation method in the present application can adapt to the installation of the clip 4 and also allows the sleeve core 5 to be smoothly inserted into the right-angle steel column 1 after the right-angle steel beam 2 is installed.

[0052] S4. Fix the right-angle steel beam 2, press the blocks 42 on both sides to move it toward the inside of the rectangular notch 11 until the blocks 42 are flush with the outer surface of the right-angle steel column 1, take a right-angle steel beam 2 and push it toward the position between the adjacent right-angle steel columns 1. When the two ends of the right-angle steel beam 2 are aligned with the corresponding rectangular notches 11, the spring 43 releases the pressure to drive the block 42 to insert into the right-angle steel beam 2 to fix it.

[0053] S5. Insert the core sleeve 5 from the upper end of the right-angle steel column 1 into the interior thereof, so that the outer wall of the core sleeve 5 is pressed against the block 42 in step S4.

[0054] S6. Apply the silicone structural adhesive layer 6 evenly on the outer surface of the right-angle steel column 1 and the right-angle steel column 1 for bonding the double-layer insulating glass 3. Apply it evenly.

[0055] S7. Press the double-layer insulating glass 3. The operator uses a vacuum glass suction cup to lift the double-layer insulating glass 3 and press it on the silicone structural adhesive layer 6 in step S6. Wait for a certain amount of time for the adhesive portion to solidify.

[0056] S8. Install the pressure plate 7 by fitting the bolts 8 with the screw holes 12 to assemble the pressure plate 7 onto the outer surface of the right-angle steel column 1 so that the pressure plate 7 is pressed tightly against the two adjacent double-layer insulating glass panels 3.

[0057] S9. Install the exposed frame cover 10, as shown Figure 4As shown, the exposed frame buckle cover 10 is slid in from top to bottom using the card slot and covers the outer surface of the pressing plate 7, thereby completing the installation of the steel support structure and the double-layer glass curtain wall.

[0058] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all embodiments.
