Description

Technical Field

[0001] The invention relates to the technical field of doors, in particular to an aluminum alloy door with a mortise and tenon sandwich structure, and also to an assembling method of the aluminum alloy door with a mortise and tenon sandwich structure. Background Art

[0002] As people's quality of life requirements continue to improve, they are no longer only concerned about functionality, but also have increasing requirements for aesthetics. Narrow-edge aluminum alloy doors are widely popular due to their large light-transmitting area and wide field of view. However, while the existing narrow-edge aluminum alloy door technology pursues a larger light-transmitting area and saves profiles, it also faces a series of challenges. The existing four-sided aluminum alloy door leaf mostly adopts a narrow profile structure design. The bottom of the door body is 10 to 30 cm close to the ground as a glass area, which lacks effective protection and is easily broken by collision.

[0003] In response to the above problems, some aluminum alloy doors on the market draw on the structure of traditional wooden doors by adding core boards to replace the glass in the bottom area. Most of these aluminum alloy doors draw on the structure of a pure wooden Chinese antique door and window disclosed in the Chinese utility model patent with announcement number CN203361874U: a middle frame is set on the inner side of the sash, glass is installed on the top of the middle frame, the core board is fixed between the middle frame and the sash, and the connection between the middle frame and the side sash is usually made of screws or middle frame connectors. When this structure is applied to aluminum alloy doors, there are the following problems: First, the glass is heavy, and the core board below itself does not bear weight, so the weight of the glass is mainly borne by the middle frame, and then transferred to the side sash by the connection point between the middle frame and the side sash. The strength of the middle frame itself and the strength of the connection at both ends are required to be high, and it is easy to crack and form a hidden danger of water leakage. Secondly, this type of middle frame structure comes from wooden doors. When it is implemented on aluminum alloy doors, there are obstacles such as many auxiliary materials and complicated processes. Summary of the invention

[0004] The invention proposes an aluminum alloy door with mortise and tenon structure, and its purpose is to solve the problems of easy cracking of the end, many auxiliary materials and complicated process when the bottom of the glass is raised by adding a middle frame and a core plate in the aluminum alloy door.

[0005] The technical solution of the present invention is as follows: A mortise and tenon sandwich structure aluminum alloy door, including sashes fixed around glass, wherein the sash at the bottom is a lower sash, and the sashes on the left and right sides are side sashes, and a sandwich is also provided between the lower sash and the glass; the top of the sandwich is connected to the bottom of the glass, and the bottom of the sandwich is connected to the top of the lower sash; the sandwich includes more than one sandwich sash that can be stacked up and down, and the left and right ends of the sandwich sash are connected to the side sashes on both sides through mortise and tenon structures.

[0006] Furthermore, the mortise and tenon structures at both ends of the clamping rail include a special-shaped groove opened on the bottom plate of the second wire-pressing groove of the clamping rail and plugged into the first overlapping structure at the inner end of the side rail, and a second protrusion extending from the bottom plate of the second wire-pressing groove and plugged into the first wire-pressing groove of the side rail.

[0007] Furthermore, the mortise and tenon structures at both ends of the clamping rail include a third protrusion extending from the top plate and the vertical plate of the second clamping groove of the clamping rail and plugged into the first pressing groove of the side rail, and a first protrusion extending from the bottom plate of the third clamping groove of the clamping rail and plugged into the first clamping groove of the side rail.

[0008] More specifically, the mortise and tenon structures at both ends of the clamping rail include a fourth protrusion extending from the top plate of the inner groove of the third overlapping structure of the clamping rail and plugged into the first snap-in groove of the side rail, and a fifth protrusion extending from the hook plate at the lower end of the third overlapping structure and cooperating with the outer hook plate of the first snap-in groove.

[0009] More specifically, the outer side of the second pressure wire groove on the upper part of the clamping stile is a second lap joint structure, the upper end of the outer plate of the second lap joint structure is connected with a second C-shaped groove through an arc plate, and the third clamping groove on the top surface of the clamping stile is clamped with a fixing strip with a first connecting rib, and the glass is clamped between the second C-shaped groove and the first connecting rib.

[0010] The second clamping groove at the bottom of the clamping stile includes an outer plate flush with the outer side surface of the clamping stile and a short plate fixed on the top surface of the second clamping groove, and the inner wall of the outer plate has an inclined surface; a fourth lap joint structure is provided on the upper part of the lower stile, and the upper end of the outer vertical plate of the fourth lap joint structure is connected to the third C-shaped groove through an arc plate, and the connection between the arc plate and the outer vertical plate of the fourth lap joint structure is a second step; the third C-shaped groove is clamped with the second clamping groove, and the bottom surface of the outer vertical plate of the second clamping groove abuts against the upper end surface of the second step.

[0011] Furthermore, the third overlapping structure at the bottom of the hall stile is clamped with the first clamping structure on the outer side of the fourth clamping groove at the upper end of the lower stile through the hook plate at its lower end.

[0012] The present invention also provides a method for assembling a mortise and tenon-jointed aluminum alloy door: The first step is to assemble the processed sashes, including the upper sash, the lower sash and the two side sashes, in sequence to complete the frame assembly; The second step is to install the stiles in each stile in sequence: first, place the stile between the two side stiles, so that the two ends of the stile are plugged into the side stiles through the mortise and tenon structure, and then press the stile downwards so that the lower end of the stile is engaged with the upper end of the lower stile or the upper end of the previous stile; The third step is to put the frame through the rubber strips and lay it flat on the installation plane. Then place the glass in the frame. Next, securely connect the four side fixing strips to the top of the topmost stile, the inside of the two side stiles, and the bottom of the upper stile. Insert the rubber strips between the fixing strips and the glass to ensure that the glass and the fixing strips are tightly attached and not loose. This completes the installation of the glass.

[0013] Compared with the prior art, the present invention has the following positive effects: (1) The present invention increases the distance between the bottom of the glass and the ground by arranging a sandwich between the lower mullion and the glass, thereby reducing the probability of the glass being broken by collision. Since the upper end of the sandwich is directly connected to the glass and the lower end is directly connected to the lower mullion, the weight of the glass can be directly transferred to the lower mullion, and the sandwich only bears pressure, thus avoiding the problem of cracking at both ends due to tension.

[0014] (2) By providing a second engaging groove at the bottom of the stile for engaging with the fourth engaging structure on the upper part of the lower stile and a third engaging structure for engaging with the fourth engaging groove on the upper part of the lower stile, not only a firm connection between the stile and the lower stile is achieved, but also the plug-in method requires fewer auxiliary materials and is simple to install.

[0015] (3) The bottom of the glass is clamped by arranging a second overlapping structure with a second C-shaped groove on the upper part of the stile and a fixing strip clamped in a third clamping groove on the upper inner side of the stile. In addition, a gasket is arranged between the bottom surface of the glass and the top surface of the uppermost stile, so that the weight of the glass can be transferred to the lower stile at the bottom of the door leaf through the gasket and the stile, thereby providing effective support for the glass.

[0016] (4) The mortise and tenon structures at both ends of the truss are tightly plugged into the side trusses on both sides of the door leaf to ensure a firm connection between the truss and the side trusses on both sides of the door leaf.

[0017] (5) By setting the lower stile with the same specifications as other slats, the types of profiles can be reduced, and the processing technology of slat splicing can be simplified, saving raw materials and reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS
