Description

Technical Field

[0001] The invention relates to a building component, in particular to a wall-connecting installation kit for doors and windows. Background Art

[0002] The traditional long steel fixing plate of metal doors and windows is installed on the wall. The steel fixing plate will extend out of the aluminum alloy frame. Because steel and cement are incompatible, water leakage along the steel fixing plate is a stubborn problem. The use of this fixing plate requires a high waterproof effect of the sealing quality between the aluminum alloy frame and the wall.

[0003] When the "J"-shaped steel fixing plate is installed on the wall, it is necessary to open a pair of holes on the aluminum alloy frame to install the fixing screws (according to the spacing required by the specification, 10 to 30 holes should be opened on each aluminum frame). Once the sealing of the pair of holes fails, it will be a direct path for water leakage. It is not easy to seal thousands of holes well. In addition, the "J"-shaped steel fixing plate does not have the fine-tuning function to adapt to the size deviation of the hole, which is inconvenient to use. The use of this fixing plate requires a high waterproof effect of the sealing quality between the aluminum alloy frame and the wall.

[0004] The snap-on steel fixing plate wall-mounted installation needs to be used together with the sub-frame, which increases the cost. In addition, a long steel fixing plate wall-mounted installation still needs to be used between the sub-frame and the wall. Therefore, it also inherits the two disadvantages listed for the traditional long steel fixing plate wall-mounted installation.

[0005] The disadvantages of directly fixing the wall with expansion screws are the same as those of the above-mentioned "J" shaped steel fixing plate wall installation. Summary of the invention

[0006] The invention provides a sub-frame-free dry-wall installation kit, which aims to solve the shortcomings of the prior art and provide a door and window installation component with simple structure, convenient installation, low cost and good waterproof effect.

[0007] The technical solution adopted by the present invention to solve its technical problem is:

[0008] The sub-frame-free dry wall installation kit is characterized by:

[0009] The kit nut is threaded on the kit bolt, the kit gasket is sleeved outside the kit nut and placed on the step at the upper end of the kit nut, the kit nut, the kit gasket and the kit bolt are combined to form a kit, and the kit bolt is provided with an axial second-order through hole consisting of a large-diameter hole and a small-diameter hole;

[0010] The kit is placed on the wall; the plastic pipe expansion screw passes through the axial second-order through hole and is screwed into the wall, and the screw head of the plastic pipe expansion screw is stuck in the large-diameter hole;

[0011] The kit gasket is embedded in the installation groove on the side of the aluminum alloy frame of the metal door and window. The hook edges on both sides of the installation groove cooperate with the steps on the upper end of the kit nut to press the kit gasket into the installation groove.

[0012] The exterior wall adhesive layer arranged on the exterior side of the aluminum alloy frame is used to bond and seal the aluminum alloy frame and the exterior wall;

[0013] An aluminum alloy water retaining edge is arranged on the aluminum alloy frame toward the indoor side, and an inner wall adhesive layer is provided to bond and seal the aluminum alloy frame and the aluminum alloy water retaining edge;

[0014] The space enclosed by the aluminum alloy frame, the kit gasket, the kit nut and the kit bolt is filled with a polyurethane foaming agent layer.

[0015] The present invention is beneficial in that:

[0016] 1: The entire kit is concealed within the coverage of the aluminum alloy frame, avoiding water leakage paths extending outside the aluminum alloy frame;

[0017] 2: This kit has a simple structure and does not require through-screw holes to be opened on the aluminum alloy frame, thus avoiding the hidden danger of water leakage caused by poor sealing of the through-screw holes on the aluminum alloy frame. The aluminum alloy frame is easy to install and is firm and reliable;

[0018] 3: This kit can fix the aluminum alloy frame directly on the wall without adding a sub-frame to use with it, avoiding the related defects caused by the sub-frame. It can realize the dry-type wall installation of the aluminum alloy frame without adding a sub-frame, which can retain the advantages of dry-type installation without adding a sub-frame, saving more than 10% of the cost;

[0019] 4: It can be easily used with the aluminum alloy water retaining edge, which greatly reduces the waterproof effect requirements for the quality of the caulking between the aluminum alloy frame and the wall; and the wall is firmly installed, and the window frame has reliable anchoring strength without the need for the bonding strength of cement mortar caulking, which can save complex caulking methods such as cement mortar caulking with complex processes and difficult quality control. Only ordinary polyurethane foaming agent is needed to caulk the joints, and the joints between the aluminum alloy frame and the wall can have excellent waterproof effects, and the cost can be saved by more than 5%;

[0020] 5: This kit has a fine-tuning function to adapt to the hole size deviation and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
