Description

Technical Field

[0001] This utility model relates to the field of metal sandwich panel installation technology, specifically to a purlin-free metal sandwich panel wall window side waterproof structure. Background Technology

[0002] With the vigorous promotion and application of prefabricated buildings in my country, metal sandwich panels are increasingly widely used in industrial and public buildings due to their advantages such as light weight, quick installation, excellent fire resistance, significant thermal insulation / sound insulation, and aesthetically pleasing facades, showing a rapid growth trend. Furthermore, the unique structural form of metal sandwich panels gives them an inherent advantage in large-span installation and fixation. In response to the national call for material and energy conservation in construction, purlin-less metal sandwich panel wall systems are gradually being applied to more building exteriors. To achieve the aesthetically pleasing and grand effect of metal sandwich panel exterior walls, more and more curtain wall window specifications are being designed and constructed in sync with the span of the sandwich panels.

[0003] In purlin-free metal sandwich panel wall systems, when the length of the curtain wall window matches the span of the sandwich panel, the conventional waterproof edging structure on the window side of the sandwich panel conflicts with the waterproof edging structure at the joint of the sandwich panel. This causes the waterproof edging structure at the joint of the sandwich panel to be interrupted by the waterproof edging structure on the window side, disrupting the continuity and integrity of the waterproof structure at the joint of the sandwich panel, affecting the overall appearance of the facade, and increasing the risk of leakage. In addition, compared with metal sandwich panels of the same span, the metal sandwich panels on the window side need to extend to the window position, so the metal sandwich panels on the window side need to be manufactured and processed separately, which increases the time and labor costs in the production and construction process. Utility Model Content

[0004] To address the technical problems existing in the prior art, this utility model provides a purlin-free metal sandwich panel wall window-side waterproof structure, which solves the problems of conflict between the window-side waterproof edge trim structure and the sandwich panel joint waterproof edge trim structure, discontinuity of the joint waterproof edge trim structure, and various cost losses in this system. The structure is reasonably designed, aesthetically pleasing and coordinated, and there is no risk of water leakage.

[0005] The present invention adopts the following technical solution:

[0006] A purlin-free metal sandwich panel wall window-side waterproof structure includes a structural column, a keel connector disposed on the outside of the structural column, a metal sandwich panel wall, a window frame auxiliary structure, and a waterproof edge-finishing structure. The metal sandwich panel wall includes a C-shaped vertical keel and a metal sandwich panel. One end of the metal sandwich panel extends to the middle of the outer side of the structural column. The end of the metal sandwich panel is fixedly connected to the web of the C-shaped vertical keel through a fastening connector. The flange of the C-shaped vertical keel is fixedly connected to the keel connector through a fastening connector. The window frame auxiliary structure is installed on the window-side of the C-shaped vertical keel for fixing the window. The straight edge of the waterproof edge-finishing structure is fitted to the outer surface of the window frame auxiliary structure, and its edge-finishing section is disposed on the outside of the metal sandwich panel.

[0007] The space formed between the waterproof edge trim structure, the window frame auxiliary structure, and the metal sandwich panel wall is filled with thermal insulation material. The end face of the waterproof edge trim structure and the end face of the metal sandwich panel wall form a butt joint after filling. The butt joint is filled with rigid thermal insulation material. The edge of the edge trim section of the waterproof edge trim structure extends into the butt joint and is fixedly connected to the web of the C-shaped vertical keel by a fastening connector that passes through the butt joint.

[0008] Preferably, the keel connector includes a first L-shaped keel and a second L-shaped keel. The first L-shaped keel and the second L-shaped keel are fixedly fixed to the outer surface of the structural column at intervals and symmetrically. The short sides of the first L-shaped keel and the second L-shaped keel are respectively fixedly connected to the structural column. The two flanges of the C-shaped vertical keel are respectively fixedly connected to the inner surfaces of the long sides of the first L-shaped keel and the second L-shaped keel. The metal sandwich panel is fixed at the middle position of the outer surface of the web of the C-shaped vertical keel. The window frame auxiliary structural component is fixedly connected to the long side of the first L-shaped keel and the flange of the C-shaped vertical keel through fastening connectors.

[0009] Preferably, the waterproof edge finishing structure includes a window-side waterproof edge finishing structure and a sandwich panel butt joint waterproof edge finishing structure. The straight edge of the window-side waterproof edge finishing structure is fitted to the outer side of the window frame auxiliary structure. The space formed between the window-side waterproof edge finishing structure, the window frame auxiliary structure, and the metal sandwich panel is filled with the thermal insulation filling material. One side of the sandwich panel butt joint waterproof edge finishing structure overlaps with one side of the window-side waterproof edge finishing structure at the butt joint, and is fixedly connected to the web of the C-shaped vertical keel by a fastening connector that passes through the butt joint. The other side of the sandwich panel butt joint waterproof edge finishing structure overlaps with the outer side of the metal sandwich panel, and butyl tape is provided at the overlap on the outer side.

[0010] Preferably, the overlapping area formed between the waterproof edge-sealing structure of the sandwich panel and the waterproof edge-sealing structure on the window side is further provided with butyl tape.

[0011] Preferably, the auxiliary structural component of the window frame is a prefabricated, U-shaped, stamped and folded integrated structural component, and its web height is not greater than the flange width of the C-shaped vertical keel.

[0012] The technical solution of this utility model has the following advantages:

[0013] A.

[0038] like Figure 1 , Figure 2 As shown, this utility model provides a purlin-free metal sandwich panel wall window-side waterproof structure, including a structural column 1, a keel connector 2 disposed on the outside of the structural column 1, a metal sandwich panel wall 3, a window frame auxiliary structure 4, and a waterproof edge trimming structure 5. The window frame auxiliary structure 4 is installed on the flange of the C-shaped vertical keel 31 in the metal sandwich panel wall 3 on the window side for fixing the window. The keel connector 2 is fixedly connected to the C-shaped vertical keel 31. The straight edge section 5a of the waterproof edge trimming structure 5 is fitted with the outer surface of the window frame auxiliary structure 4, and the edge trimming section 5b of the waterproof edge trimming structure 5 is disposed on the outside of the metal sandwich panel wall 3. One end of the metal sandwich panel 32 extends to the middle of the outer side of the structural column 1, and the end of the metal sandwich panel 32 is fixedly connected to the web of the C-shaped vertical keel 31 by a fastening connector 7.

[0039] The space formed between the waterproof edge trim structure 5, the window frame auxiliary structure 4, and the metal sandwich panel wall 3 is filled with thermal insulation material 6. The end face of the waterproof edge trim structure 5 after filling forms a butt joint a with the end face of the metal sandwich panel wall 3. The butt joint a is filled with rigid thermal insulation material 9. The edge of the edge trim section 5b of the waterproof edge trim structure 5 extends into the butt joint a and is fixedly connected to the metal sandwich panel wall 3 through the fastening connector 7 that penetrates the rigid thermal insulation material 9 in the butt joint a.

[0040] The keel connector 2 in this utility model includes a first L-shaped keel 21 and a second L-shaped keel 22. The first L-shaped keel 21 and the second L-shaped keel 22 are fixed to the outer surface of the structural column 1 at intervals and symmetrically. The short sides of the first L-shaped keel 21 and the second L-shaped keel 22 are respectively fixed to the structural column 1 by welding. The window frame auxiliary structural component 4 can be fixed to the flange of the C-shaped vertical keel 31 by welding. The metal sandwich panel wall 3 used in this utility model includes a C-shaped vertical keel 31 and a metal sandwich panel 32. The metal sandwich panel 32 is fixed to the middle of the outer side of the web of the C-shaped vertical keel 31. The two flanges of the C-shaped vertical keel 31 are respectively fixed to the inner side of the long side of the first L-shaped keel 21 and the second L-shaped keel 22 by fastening connectors. Figure 1Each flange of the C-shaped vertical keel 31 is fixedly connected by fastening connectors, and the number of fixing points on each flange is not less than 2. Figure 1 In the middle, the metal sandwich panel 32 extends to the middle of the C-shaped vertical keel 31. The metal sandwich panel 32 is fixedly connected to the web of the C-shaped vertical keel 31 by fastening connectors, and the number of fixing points is not less than 2.

[0041] The auxiliary structural component 4 of the window frame here is a prefabricated punched and folded integrated structural component. It is U-shaped as a whole, and its web height is no greater than the flange width of the C-shaped vertical keel 31. This structural component is intended to assist in the installation of the window and the waterproof edge trim structure on the side of the window.

[0042] The waterproof edge-sealing structure 5 used in this utility model includes a window-side waterproof edge-sealing structure 51 and a sandwich panel butt joint waterproof edge-sealing structure 52, such as... Figure 2 As shown, the straight edge of the window-side waterproof edge trim structure 51 is fitted to the outer side of the window frame auxiliary structure 4. The space formed between it, the C-shaped vertical keel 31, the window frame auxiliary structure 4, and the metal sandwich panel 32 is filled with thermal insulation material 6. One side of the sandwich panel butt joint waterproof edge trim structure 52 overlaps with one side of the window-side waterproof edge trim structure 51 at the butt joint a. In this utility model, rigid thermal insulation material is embedded in the butt joint. At the overlap, a fastening connector 7 that penetrates the butt joint a forms a fixed connection with the web of the C-shaped vertical keel 31. The other side of the sandwich panel butt joint waterproof edge trim structure 52 overlaps on the outer side of the metal sandwich panel 32, and butyl tape 8 is provided at the overlap on the outer side. In addition, in this utility model, the overlapping area formed between the waterproof edge-sealing structure 52 of the sandwich panel joint and the waterproof edge-sealing structure 51 of the window side is also provided with butyl tape 8. The waterproof edge-sealing structure 52 of the sandwich panel joint is fixedly connected to the web of the C-shaped vertical keel 31 through the fastening connector 7, so as to ensure that the waterproof edge-sealing structure of the sandwich panel joint and the butyl tape 8 are pressed tightly.

[0043] The length of the metal sandwich panel 32 in the window side area of ​​this utility model does not need to extend to the window position. The specifications of the metal sandwich panel in this area are consistent with those of the metal sandwich panel of the same span, and it can be designed, cut, purchased and installed normally. After the metal sandwich panel 32 is installed, thermal insulation filling material 6 and rigid thermal insulation filling material 9 are embedded in the window side and the joint of the metal sandwich panel, respectively. The waterproof edge-sealing structure 52 of the sandwich panel joint in the window side area is temporarily fixed in the joint. A layer of butyl tape 8 is attached to the overlapping area of ​​the waterproof edge-sealing structure of the sandwich panel joint in the window side area. Then, the waterproof edge-sealing structure 51 of the window side area and the waterproof edge-sealing structure 52 of the sandwich panel joint are overlapped at the joint, so that the butyl tape 8 at the overlap is pressed tightly to ensure the waterproof effect.

[0044] Figure 2This diagram illustrates the positional relationship between the window-side waterproof edge trim structure 51, the butyl tape 8, and the window-side area sandwich panel joint waterproof edge trim structure 52 at the joint of the sandwich panels. The two waterproof edge trim structures are a combined type. The window-side waterproof edge trim structure 51 can coexist reasonably with the sandwich panel joint waterproof edge trim structure 52, preventing the sandwich panel joint waterproof edge trim structure 52 in the window-side area from being damaged. This enhances the aesthetic and harmonious effect of the exterior wall facade, significantly improving its visual appeal.

[0045] The specific construction method of this utility model includes:

[0046] Step 1, purlin-less structural system composition: After the keel connectors are welded to the structural columns in the processing plant, they are transported to the construction site for installation. The keel connectors need to be precisely marked, positioned, and installed on the flange of the structural column according to the cross-sectional size of the C-shaped vertical keel, ensuring that space is reserved for the normal installation of the C-shaped vertical keel.

[0047] Step 2: Install the C-shaped vertical keel between the keel connectors using fastening fasteners, with no fewer than two fixing points on each side; fix the metal sandwich panel to the C-shaped vertical keel using fastening fasteners, with two fixing points. Strict control must be exercised over the measurement and layout process during the installation of the C-shaped vertical keel to minimize installation errors, thereby ensuring the flatness and aesthetics of the metal sandwich panel.

[0048] Step 3: Fix the U-shaped window frame auxiliary structural components to the C-shaped vertical keel.

[0049] When fixing the U-shaped window frame auxiliary structural components to the C-shaped vertical keel, they can be welded or fixed using flat-head fasteners. When using welding, care should be taken to remove slag and prevent rust.

[0050] Step 4: Fill the window side and sandwich panel joint with insulation material, and install the window side waterproof edge trim structure and the sandwich panel joint waterproof edge trim structure.

[0051] To ensure the rationality and effectiveness of the structural waterproofing, before the installation of the waterproofing edge trim structure at the window side and the joint of the sandwich panel, a layer of butyl tape should be applied at the junction of the waterproofing edge trim structure at the joint of the metal sandwich panel and the joint of the sandwich panel, and at the junction of the waterproofing edge trim structure at the window side and the joint of the sandwich panel. After the waterproofing edge trim structure is installed, the butyl tape should be pressed tightly.

[0052] Step 5: Install the window. Apply weather-resistant sealant to the junction of the window and the waterproof edge trim structure on the side of the window.

[0053] Weather-resistant sealant is applied at the junction of the window and the waterproof edge trim structure on the window side, and at the junction of the waterproof edge trim structure on the window side and the waterproof edge trim structure at the joint of the sandwich panel in the non-window area.

[0054] In summary, the effective combination and installation of the window-side waterproof edge trim structure and the sandwich panel joint waterproof edge trim structure, along with scientific construction methods, allows the two waterproof edge trim structures to coexist reasonably, maintaining the continuity of the sandwich panel joint waterproof edge trim structure. The sandwich panels in the window-side area do not need to be produced separately. While ensuring basic waterproofing functions, this enhances the aesthetic and harmonious effect of the exterior wall facade and saves on various costs.

[0055] Any aspects not described herein are applicable to the prior art.

[0056] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
