Description

Technical Field

[0001] The invention belongs to the technical field of building decoration, and in particular relates to a backboard-free slotted plug-in aluminum plate curtain wall system. Background Art

[0002] The curtain wall is the exterior wall of a building. It does not bear weight and is hung like a curtain, so it is also called a "curtain wall". It is a lightweight wall with decorative effects commonly used in modern large and high-rise buildings. It is composed of panels and a supporting structure system. It can have a certain displacement ability relative to the main structure or a certain deformation ability itself. It is a building exterior protective structure or decorative structure that does not bear the effects of the main structure. Curtain walls have many functions. Depending on the type, the emphasis of the curtain wall function is also different. Sealing with glue can play the role of exterior protection and decoration, and the slit type without glue plays a decorative role.

[0003] Typically used for decorative purposes only, these slit-type, non-glue-coated aluminum curtain walls consist of a system of aluminum panels, pre-embedded or post-embedded steel parts, steel columns, and steel beams connected by welding or bolts. For corrosion protection, a layer of galvanized steel or aluminum is laid on the outer layer of the steel structure. In coastal areas, this system, if galvanized steel is used for the back panel, will experience severe corrosion over time. The "yellow water" from the corrosion will seep onto the panel, severely affecting the decorative effect. Over extended use, corrosion penetration can easily create safety hazards. If aluminum is used for the back panel, many holes are opened at the junction with the mounting brackets, and all of them are sealed with weather-resistant glue. This involves multiple processes and is costly. The reliability of the back panel's sealing cannot be guaranteed. Furthermore, due to non-standard construction practices, the aluminum panel is susceptible to electrochemical corrosion from contact with the steel, which can also lead to quality issues. Summary of the Invention

[0004] The purpose of the present invention is to provide a backboard-free, slotted, plug-in aluminum panel curtain wall system, which can ensure the decorative function of the aluminum panel curtain wall, and adopts aluminum alloy molds to make profiles, thereby reducing the cost and creating economic benefits for large-scale production; no backboard is used, and no glue is applied, thereby reducing costs and preventing pollution; it can be entirely processed in the factory, and the on-site installation is simple, the work intensity is reduced, the positioning is accurate, and the beauty of the exterior surface is guaranteed.

[0005] The technical solutions adopted by the present invention are as follows: A back-free slotted plug-in aluminum panel curtain wall system, comprising a slotted embedded part embedded in a building main body, one side of the slotted embedded part being connected to two slotted aluminum alloy angle brackets by T-shaped stainless steel bolts, and a first square steel being fixed between the outer walls of the two slotted aluminum alloy angle brackets by stainless steel bolts; Two connecting pieces are fixed on both sides of the first square steel by hexagonal bolts, a second square steel is fixed to one side of the connecting piece by hexagonal bolts, a male hanging code is fixed to the bottom of the second square steel by self-tapping screws, a female hanging code is plugged into one side of the male hanging code, and an aluminum veneer is fixed to one side of the female hanging code and the male hanging code by countersunk screws.

[0006] The connection between the angle bracket and the connecting piece and the first square steel is provided with a rubber gasket.

[0007] An EPDM rubber strip is arranged between the female hanging weight and the male hanging weight.

[0008] A construction method for a back-free slotted plug-in aluminum panel curtain wall system, the specific steps are as follows: Step 1: The trough-type embedded parts are embedded in parallel with the civil engineering work. Before pouring concrete, the binding and welding of the stainless steel trough-type embedded parts must be completed and reviewed and accepted. The position and elevation of the trough-type embedded parts must comply with the requirements of the embedded parts design layout drawing. Step 2: After re-measurement of the structure, the horizontal and vertical positions of the special slot aluminum alloy angle brackets are determined by laying out the lines, and the corresponding special slot aluminum alloy angle brackets are adjusted. After the three-dimensional spatial positioning of the special slot aluminum alloy angle brackets is accurately determined, the special slot aluminum alloy angle brackets are first tightened and fixed with T-shaped stainless steel bolts and special slot aluminum alloy pads, and then the aluminum alloy columns are fixed; Step 3: Install the aluminum alloy columns from bottom to top. If there are continuous columns above the first column, the end with the core sleeve should face upwards. First, use a stainless steel bolt assembly and a special slotted aluminum alloy gasket to fix the upper end. After adjusting the accurate position, fix the lower end. For the second column, align the lower end with the core sleeve of the first column and leave a 20mm expansion joint. Then, hang the wire or align the upper end of the installation beam, and install it upwards in this order. Step 4: After all the columns are installed, install the beams. Before installing the beams, first insert the connectors into both ends of the beams, support the beams, and tighten them with stainless steel hexagonal bolts on both sides, and then tighten them on the columns with stainless steel hexagonal bolts; Step 5: Install the fireproof layer and smoke-proof panels, and use galvanized steel plates to continuously seal the edges of the curtain wall and each floor slab; Step 6: The aluminum veneer is installed using the left and right up and down plug-in method of male and female hanging codes. First, the positioning and marking should be carried out, and control points should be set outside the frame plane. The control lines should be pulled to control the flatness of the installation and the position of each component. The aluminum veneer is lifted up, and the aluminum veneer is aligned with the notch on the left and bottom of the column and beam. The aluminum alloy clips that have been positioned and fixed are inserted slowly. Then, the hanging codes of the right and upper aluminum veneers are fixed with stainless steel self-drilling screws. The first side plate is fixed. The other aluminum veneers are inserted in the order of male and female hanging codes, and the gap size is fine-tuned with gaskets to meet the design requirements. Step seven, install the aluminum veneer at the openable part, install the aluminum veneer in the middle of the aluminum alloy column, and use the full-length aluminum alloy clip to connect the edge of the open part. First assemble the second square steel to make the door frame and the door frame aluminum veneer, use the ordinary side nailing method to fix the aluminum veneer, and then use the stainless steel shaft to fix it in the middle of the aluminum plate aluminum alloy beam.

[0009] In one of the steps, if the groove-type embedded parts cannot be pre-embedded or are missed in the project, stainless steel plate embedded parts are used in combination with stainless steel chemical anchor bolts to replace the stainless steel groove-type embedded parts, and stainless steel connectors and stainless steel post-embedded parts are welded and fixed to the aluminum alloy columns.

[0010] In the fourth step, the holes on the column and the holes of the aluminum alloy angle brackets should be transition-fitted, and the size of the holes should be 0.1 to 0.2 mm larger than the diameter of the screw.

[0011] In the fourth step, noise-proofing treatment is performed between the beam and the column. The size of the entire beam should be 4 to 4.5 mm shorter than the grid size, and 2 mm noise-proof isolation plates are installed at both ends of the beam. During the installation of the beam, the height of both ends of the beam should be controlled within the range of ±1 mm; the elevation deviation on the same surface should not exceed 3 mm.

[0012] In the above steps, the fireproof material should be a product with a fireproofing grade of not less than 1.5 hours, a density of 100 kg / m3 of rock wool, and a thickness of 200 mm.

[0013] In step six, the aluminum veneer is first fixed with the male and female hanging weights in the factory using countersunk screws and nuts according to the processing drawings, and the male and female hanging weights are threaded with EPDM strips and transported to the project site as spare aluminum veneer.

[0014] The technical effects achieved by the present invention are: The invention ensures the decorative function of the aluminum plate curtain wall, adopts aluminum alloy molds to produce profiles, reduces the cost, and creates economic benefits for large-scale production.

[0015] The present invention does not use a backboard or glue, which fundamentally eliminates the rust problem of the backboard caused by long-term humidity or coastal environment, avoids the "yellow water" caused by corrosion from contaminating the panel, and ensures that the curtain wall maintains a neat decorative effect for a long time. It is especially suitable for high humidity and salt spray environments, and also reduces costs while preventing pollution. The male hanging bracket and the female hanging bracket provided in the present invention are connected by EPDM rubber strips, which not only realizes flexible connection, but also isolates the external water vapor corrosion, thereby improving the overall weather resistance of the system; in addition, a plug-in hanging bracket design is adopted, which is assisted by positioning markings and control lines to realize the quick left and right and up and down connection of the aluminum single plate, and the gap is fine-tuned with gaskets, which greatly simplifies the installation process, reduces the intensity of on-site operations, and improves the installation efficiency.

[0016] The aluminum veneer and male and female hanging brackets provided in the present invention are pre-installed in the factory, and only need to be plugged in and installed on site, which reduces on-site processing losses and improves material utilization. At the same time, it creates conditions for large-scale industrial production and significantly improves economic benefits. The on-site installation is simple, the work intensity is reduced, the positioning is accurate, and the beauty of the exterior surface is guaranteed.

[0017] The present invention provides a noise-proof isolation sheet between the crossbeam and the columns, which effectively absorbs the stress caused by the thermal expansion and contraction of the aluminum alloy frame, reduces friction noise, and improves the comfort of use; the columns are connected by core sleeves and expansion joints are reserved to adapt to the deformation of the building body and enhance the seismic performance of the system.

DETAILED DESCRIPTION

[0020] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following examples. It should be understood that the following text is only used to describe one or more specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0021] like Figure 1-Figure 3 As shown, a back-free slotted plug-in aluminum panel curtain wall system includes a slot-type embedded component 1 embedded in the main body of the building. One side of the slot-type embedded component 1 is connected to two slotted aluminum alloy angle brackets 2 by T-shaped stainless steel bolts. A first square steel 3 is fixed between the outer walls of the two slotted aluminum alloy angle brackets 2 by stainless steel bolts. Two connecting pieces 4 are fixed to both sides of the first square steel 3 by hexagonal bolts, a second square steel 5 is fixed to one side of the connecting piece 4 by hexagonal bolts, a male hanging weight 7 is fixed to the lower part of the second square steel 5 by self-drilling screws, a female hanging weight 6 is inserted into one side of the male hanging weight 7, and an aluminum veneer 8 is fixed to one side of the female hanging weight 6 and the male hanging weight 7 by countersunk screws; A rubber gasket 10 is provided at the connection between the angle bracket 2 and the connecting piece 4 and the first square steel 3; An EPDM rubber strip 9 is provided between the female hanging weight 6 and the male hanging weight 7 .

[0022] According to the above structure, rubber gaskets 10 are embedded at the connection between the angle bracket 2 and the connecting piece 4 and the first square steel 3 to ensure tight installation and play a buffering and sealing role; the installation status of the EPDM strip 9 between the female hanging bracket 6 and the male hanging bracket 7 is checked to ensure that the strip is complete and the position is accurate to achieve a good sealing effect; the aluminum single plate 8 is pre-installed with the male hanging bracket 7, the female hanging bracket 6 and the strip in the factory, and only plugging and simple fixing are required on site, which greatly reduces the intensity of on-site operations and the difficulty of construction.

[0023] like Figure 1-Figure 3 As shown, a construction method of a back-free slotted plug-in aluminum panel curtain wall system, the specific steps are as follows: Step 1: The trough-type embedded parts 1 are embedded in parallel with the civil engineering work. Before the concrete is poured, the binding and welding of the stainless steel trough-type embedded parts 1 must be completed and reviewed and accepted. The position and elevation of the trough-type embedded parts 1 must comply with the requirements of the embedded parts design layout drawing. If the slot-type embedded parts 1 cannot be pre-buried or are omitted in the project, stainless steel plate embedded parts combined with stainless steel chemical anchor bolts can be used to replace the stainless steel slot-type embedded parts 1, and stainless steel connectors and stainless steel post-embedded parts can be welded to fix the aluminum alloy columns. The slot-type embedded parts 1 are used because the slotted aluminum plate curtain wall does not use a back plate to cover the keel and has superb corrosion resistance, meeting the durability requirements of humid weather in coastal areas. Step 2: After re-measurement of the structure, the horizontal and vertical positions of the special slot aluminum alloy angle bracket 2 are determined by laying out the lines, and the special slot aluminum alloy angle bracket 2 is adjusted accordingly to ensure the accurate installation of the column. After the three-dimensional spatial positioning of the special slot aluminum alloy angle bracket 2 is accurately determined, the special slot aluminum alloy angle bracket 2 is first tightened and fixed with T-shaped stainless steel bolts and special slot aluminum alloy pads. The spatial positioning is checked again to ensure that it is correct before fixing the aluminum alloy column. Step 3: Install the aluminum alloy columns from bottom to top. If there are continuous columns above the first column, the end with the core sleeve should face upwards. First, use a stainless steel bolt assembly and a special slotted aluminum alloy gasket to fix the upper end. After adjusting the accurate position, fix the lower end. For the second column, align the lower end with the core sleeve of the first column and leave a 20mm expansion joint. Then, hang the wire or align the upper end of the installation beam, and install it upwards in this order. Step 4. Install the beam after all the columns are installed. Before the beam is installed, first insert the 4mm thick connector 4 into both ends of the beam to support the beam. Use 2 stainless steel hexagonal bolts on each side to lock it, and then use 2 stainless steel hexagonal bolts to lock it on the column. The beam bears the weight of the aluminum plate and is prone to torsion. Therefore, the holes on the column and the slots of the aluminum alloy angle code 2 should be transitionally matched, and the hole size should be 0.1 to 0.2 mm larger than the screw diameter; since the aluminum alloy skeleton will generate noise due to thermal expansion and contraction, considering this factor, noise prevention treatment should be performed between the beam and the column. The size of the entire beam should be 4 to 4.5 mm shorter than the grid size, and 2 mm noise-proof isolation sheets should be installed at both ends of the beam; during the installation of the beam, the height of the two ends of the beam should be controlled within the range of ±1 mm; the elevation deviation of the same surface should not exceed 3 mm; Step 5: Install the fireproof layer and smokeproof panels, and use 1.5mm galvanized steel plates to continuously seal the edges of the curtain wall and each floor slab. The fireproof material should be rock wool with a fire rating of no less than 1.5 hours, a density of 100 kg / m3, and a thickness of 200 mm. 8 and 6. Step seven, install the aluminum veneer 8 at the openable part, install the aluminum veneer 8 in the middle of the aluminum alloy column, and use the full-length aluminum alloy clip to plug in the edge of the open part. First assemble the second square steel 5 to make the door frame and the door frame aluminum veneer 8, use the ordinary side nailing method to fix the aluminum veneer 8, and then use the stainless steel shaft to fix it in the middle of the aluminum plate aluminum alloy beam.

[0024] According to the above construction method: all profiles are made of aluminum alloy molds to reduce construction costs and create economic benefits for large-scale production; no backboard is used and no glue is applied, which reduces costs and prevents pollution; all can be processed in the factory, which makes on-site installation simple, reduces work intensity, and ensures accurate positioning to ensure the beauty of the exterior finish; in addition, as a solution to the serious corrosion problem of the slotted aluminum curtain wall system in coastal areas, the materials used themselves have long-term corrosion resistance; as for curtain wall glue pollution, the aluminum curtain wall system used does not use weather-resistant glue and other glue substances, which is more green and environmentally friendly; as for the shielding effect of the exterior wall components, an openable solution is adopted for the maintenance and use of fire hydrants.

[0025] The foregoing is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained herein shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
