Description

TECHNICAL FIELD

[0001] The utility model relates to the field of building doors and windows, in particular to a dry installation structure of door and window. BACKGROUND

[0002] Figure 1 An existing dry installation structure is shown, and it can be seen that the conventional method of dry fixing is to pre-bury a secondary frame 100 in a building body 101, and then directly fix a window frame 20 in the building body 101 through fasteners vertically. This fixing method requires that the secondary frame 100 must be pre-set when the vertical surface of the building body 101 is cast, which increases the steps when the frame is built and has a higher requirement for the management of the construction site. Moreover, due to the post-positioning of the door and window suppliers of some projects, the supplier cannot pre-set the secondary frame when the project is in the late pouring stage. SUMMARY

[0003] In order to overcome the above-mentioned defects of the prior art, the purpose of the utility model is to provide a dry installation structure of door and window, which postpones the process of setting the secondary frame in the dry installation to the period between the pouring of the wall body and the indoor decoration, thereby reducing the construction requirements.

[0004] In order to achieve the above-mentioned purpose, the technical scheme adopted by the utility model is:

[0005] A dry installation structure of door and window, a movable sash is arranged on a window frame, the window frame is fixed on a concrete layer through a dry structure, angle steels with first connecting surfaces and second connecting surfaces are arranged on the inner and outer sides of the window frame, the first connecting surfaces of the angle steels are tightly connected with the side surfaces of the window frame through fasteners, the second connecting surfaces are fixed on the concrete layer through expansion nails, and the first connecting surfaces and the second connecting surfaces are connected through bending.

[0006] In one preferred embodiment of the utility model, the window frame is arranged on the concrete layer through a flat substitute wood, and fasteners that are fixed in the concrete layer are arranged on the substitute wood.

[0007] In one preferred embodiment of the utility model, at least one pair of first supporting pieces are arranged at the bottom of the window frame, and the first supporting pieces are located at the inner and outer edge edges of the window frame to ensure that the window frame is flat and is arranged on the substitute wood.

[0008] In one preferred embodiment of the utility model, at least one pair of second supporting pieces are arranged at the bottom of the window frame, and the second supporting pieces are located at the middle position of the window frame relative to the first supporting pieces.

[0009] In one preferred embodiment of the utility model, the first supporting pieces and the window frame are connected through clamping. In one preferred embodiment of the utility model, the first supporting pieces and the window frame are connected through clamping.

[0010] In a preferred embodiment of the present application, a step for pre-positioning is further arranged on the concrete layer, and the wooden block is arranged on the step.

[0011] The present application has the advantages that:

[0012] The dry installation structure of the door and window provided by the present application has the wooden block arranged at the bottom of the window frame to level the floor, and the angle steel arranged at the two sides to stabilize the horizontal position, so that the installation position of the door and window only needs to be reserved at the construction site, and the sub-frame does not need to be cast in the building body in advance. BRIEF DESCRIPTION OF DRAWINGS

[0016] In the description of the present application, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and the above description is simplified for the convenience of describing the present application, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0017] The singular forms "a", "said" and "the" used in the specification are intended to include plural forms unless clearly indicated otherwise. The terms "comprise", "include" and "contain" used in the specification mean that the claimed features exist, but do not exclude the existence of one or more other features. The term "and / or" used in the specification includes any and all combinations of one or more of the related listed terms.

[0018] In the specification, when one element is referred to as being "on", "fixed to", "connected to", "joined to" or the like another element, the element can be directly on, fixed to, connected to, joined to or in contact with the other element, or there can be an intermediate element.

[0019] It will be understood that, although the terms "first", "second", etc. can be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. Thus, a first element could be termed a second element without departing from the teachings of the present application.

[0020] Exemplary embodiments of the present application will be described below with reference to the accompanying drawings. It is to be understood, however, that the present application can be presented in many different ways and is not limited to the embodiments described below. It is also to be understood that the embodiments disclosed herein can be combined in various ways to provide additional embodiments. In all the drawings, the same reference numerals designate the same or functionally similar elements.

[0021] Figure 1 A cross-sectional view of the mounting structure is shown. It can be seen that the window frame 20 is mounted on the concrete layer 3 without damage by the use of a substitute wood 1, which serves as a leveling layer between the concrete layer 3 and the window frame 20, ensuring that the bottom of the window frame 20 is mounted on a flat surface. A step 4 is provided on the concrete layer 3, which protrudes upward and serves as a positioning platform for the installation of the door and window. Two long fasteners 11 are vertically inserted into the substitute wood 1 and the step 4 from top to bottom to fix the substitute wood 1. Since the window frame 20 is made of a broken bridge aluminum alloy structure, the bottom of the window frame 20 has a downward extending buckle structure. In order to ensure that the bottom of the window frame 20 is stably connected to the substitute wood 1, a first support 22 and a second support 23 are provided at the bottom of the window frame 20. The first support 22 is arranged near the edges of the indoor and outdoor sides of the window frame 20 and is fixed to the buckle structure 20a below the window frame 20 by a clamping structure, so that the window frame 20 can be supported on the substitute wood 1 from both sides. The second support 23 is arranged at the middle position of the lower side of the window frame 20. The support at this position allows the middle part of the window frame 20 to transmit the force to the substitute wood 1 through the second support 23, avoiding the collapse of the middle part of the window frame 20 under stress. A pair of angle steels 30 are arranged on the indoor and outdoor sides of the window frame 20, respectively. The angle steel 30 has a first connecting surface 30a and a second connecting surface 30b, which are connected by being bent at 90°. The first connecting surface 30a is tightly fitted to the indoor or outdoor surface of the window frame 20 and is fixed by a fastener 21. The second connecting surface 30b is fixed to the concrete layer 3 by an expansion nail 31. This structure is different from the typical wet installation process. The window frame 20 is not provided with any destructive fixing method in the vertical direction. It is only fixed on the two sides by the fastener 21 and the angle steel 30. The horizontal position of the window frame 20 is ensured by the two angle steels 30. Since the volume of the fastener 21 is small and the hole is shallow, the damage to the window frame 20 is limited and the influence on the heat insulation and conduction performance is small.

[0022] When the window frame 20 is installed through the angle steel 30, the cement layer 2 is poured on both sides and leveled, and the installation is completed.
