Description

Technical Field

[0001] This invention relates to the field of building door and window installation technology, specifically to a connection structure and installation method for a large-span energy-saving door and window. Background Technology

[0002] The conventional practice for window systems is to connect the steel subframe to the main structure using 1.5mm thick Q235 steel sheets. Since there are many steel sheets, it's inconvenient to adjust their dimensions to accommodate structural deviations. Therefore, adjustments to the main structure deviation are often made using shims between the steel subframe and the window frame. The connection between the window frame and the subframe is typically a self-drilling screw. When the main structure deviation is large, the distance between the window frame and the steel subframe is significant. The self-drilling screws connecting them must withstand not only shear force but also bending moments generated by the large distance, which is detrimental to their stress distribution. Furthermore, large-span window systems bear even greater loads, placing higher demands on the connecting components.

[0003] Therefore, this invention proposes a connection structure and installation method for a large-span energy-saving door and window that facilitates adjustment of the distance between the window frame and the steel subframe. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a connection structure and installation method for a large-span energy-saving door and window, wherein the connection between the window frame and the steel sub-frame is firm and the connection structure for the large-span energy-saving door and window is easy to install and adjust.

[0005] The technical solution of the present invention is as follows: A connection structure for a large-span energy-saving door and window includes an aluminum alloy vertical frame, an aluminum alloy side frame, a steel sub-frame, and aluminum alloy profiles. The aluminum alloy side frame is fixedly fitted with an aluminum alloy vertical frame. A glass panel assembly is mounted on the exterior-facing side of both the aluminum alloy vertical frame and the aluminum alloy side frame. The glass panel assembly is fixed to the aluminum alloy profiles via adhesive strips. The aluminum alloy profiles are fixedly connected to the aluminum alloy side frame. An aluminum alloy glass support strip is positioned at the connection between the aluminum alloy profiles and the aluminum alloy side frame at the downward-facing end of the glass panel assembly. An aluminum alloy window connector is mounted on the aluminum alloy side frame. The window connector has a set of aluminum alloy toothed plates. A second toothed groove, matching the size of the first toothed groove of the aluminum alloy toothed plate, is also provided on the window connector. A set of elongated holes for adjusting the vertical position of the steel sub-frame is also provided on the window connector. The first toothed groove of the aluminum alloy toothed plate engages with the second toothed groove of the aluminum alloy window connector, and the connector is fixed to the elongated holes and the steel sub-frame via bolt assemblies passing through the aluminum alloy toothed plates.

[0006] Furthermore, the aluminum alloy frame includes an outer frame and an inner frame, which are fixedly connected by a heat insulation strip; the outer frame has a bolt assembly groove for connecting aluminum alloy profiles on the outdoor side.

[0007] Furthermore, the inner frame includes an inner frame body, with symmetrically arranged bent portions on both sides of the bottom end of the inner frame body, the two bent portions forming an installation groove for installing aluminum alloy window connectors; the inner frame body has a connecting groove for connecting aluminum alloy glass support strips on the side facing the glass assembly.

[0008] Furthermore, the aluminum alloy window connector is composed of a horizontal connector plate and a vertical connector plate perpendicular to the bottom of the horizontal connector plate. The elongated hole is opened in the length direction of the vertical connector plate to adjust the vertical position of the steel sub-frame. The second tooth groove is provided on the surface of the vertical connector plate facing the aluminum alloy tooth plate.

[0009] Furthermore, the aluminum alloy window connector is connected to the inner frame through a connection between the horizontal plate of the connector and the mounting groove; the steel sub-frame is located on the side of the vertical plate of the connector facing the interior.

[0010] Furthermore, the aluminum alloy toothed plate has through holes. The aluminum alloy toothed plate and the aluminum alloy window connector are fixed by bolts passing through the through holes, elongated holes and steel sub-frame after the toothed plate and toothed groove one and toothed groove two mesh.

[0011] Furthermore, a glass pad is provided between the steel sub-frame and the horizontal plate of the connector; the steel adapter of the steel sub-frame is fixedly connected to the embedded part on the main body.

[0012] Furthermore, the end of the connecting aluminum alloy glass support strip is installed in the connecting groove, and a glass pad is provided between the glass panel and the connecting aluminum alloy glass support strip.

[0013] Furthermore, the inner frame body has a set of screw holes inside, and the aluminum alloy vertical frame is fixed to the inner frame by screws passing through the screw holes.

[0014] This invention also proposes an installation method for the connection structure of large-span energy-saving doors and windows, comprising the following steps: 1) First, assemble the aluminum alloy vertical frame and aluminum alloy side frame by passing screws through the screw holes; 2) Then install the horizontal plate of the aluminum alloy window connector into the mounting groove one, and then install the aluminum alloy toothed plate on one side of the aluminum alloy window connector. 3) Based on the actual situation, the position of the steel sub-frame and the aluminum alloy frame can be adjusted by adjusting the meshing of the first tooth groove of the aluminum alloy tooth plate with the second tooth groove of the aluminum alloy window connector. 4) After the position is adjusted in step 3), a glass pad is placed between the steel sub-frame and the aluminum alloy frame. Finally, the glass is fixed by bolts passing through the through holes, elongated holes and the steel sub-frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1) By adopting the technical solution of the present invention, a set of elongated holes are provided on the aluminum alloy window connector. By adjusting the position of the bolt assembly above and below the elongated holes, the distance between the steel sub-frame and the aluminum alloy frame can be adjusted on the one hand, and the installation deviation can also be adjusted on the other hand. 2) Compared with the traditional method of connecting the window frame and the sub-frame with self-drilling screws, the aluminum alloy window connector of the present invention is connected to the inner frame by the cooperation of the horizontal plate of the connector and the mounting groove. The steel sub-frame is set on the side of the vertical plate of the connector facing the interior, which avoids the damage to the cross section of the window frame profile caused by the process holes of the self-drilling screws and reduces the processing of process holes. 3) In this invention, the first tooth groove of the aluminum alloy toothed plate meshes with the second tooth groove of the aluminum alloy window connector to prevent the bolt assembly from moving. 4) The aluminum alloy frame and the steel sub-frame of this invention are firmly connected, and the distance between them is easy to adjust.
