Description

Technical Field

[0001] The utility model belongs to the technical field of door and window frame fixing, and in particular relates to an assembled building door and window frame fixing connector. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, transported to the construction site, and assembled and installed on-site through reliable connection methods. During the prefabricated building processing process, door and window openings are reserved in advance to facilitate the later installation of door and window frames.

[0003] Prefabricated buildings generally use composite structures that integrate a variety of different materials and structures. During the later process of fixing door and window frames, the existing technology uses bolt fixing methods that can easily damage the wall structure and affect the effect of the wall structure. There is currently a lack of special door and window connectors to avoid damage to the wall structure. Utility Model Content

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of the application are only for the purpose of describing specific embodiments and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0033] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] The present invention provides a prefabricated building door and window frame fixing connector. Figure 1-Figure 5 As shown, the assembled building door and window frame fixing connector includes:

[0035] The card base 100 includes a card block 110, a base 120, and a sliding area 130 provided on the base 120;

[0036] The supporting block 200 is provided with a push column 220; the supporting block 200 slides in the sliding area 130, and a spring 140 is provided between the supporting block 200 and the bottom bracket 120. The supporting block 200 is elastically connected to the base 100 via the spring 140;

[0037] The pushing member 400 includes a pushing plate 410, a screw 420, and a screw hole support 430. The screw 420 extends from a guide hole provided in the side wall of the base 100 into the sliding area 130. The screw hole support 430 is provided on the base 120. The screw 420 rotates along the screw hole support 430. During the screw rotation process, the pushing plate 410 located at the front end of the screw 420 pushes the abutting block 200 away from the base 100.

[0038] By prefabricating several groups of slots 500 in the wall 600 of the prefabricated building in advance, the card seat 100 is then used to cooperate with the slots 500 to press the side of the card seat 100 away from the abutting block 200 into the interior of the card slot 500. Subsequently, the distance between the abutting block 200 and the card seat 100 is changed by adjusting the pusher 400, and the prefabricated building door and window frames are abutted and fixed by using multiple groups of fixing connectors. It should be noted that when the card seat 100 is engaged in the slot 500, the guide hole provided on the side wall of the card seat 100 is still located outside the slot 500, because a wrench is required to rotate the screw 420 to drive the push plate 410 to move; the screw 420 is provided with a hexagonal groove at the end away from the push plate 410 for the hexagonal wrench to perform the rotation operation.

[0039] Since the wall 600 of the prefabricated building will be prefabricated with an insulation layer and a sound insulation layer structure during the processing, in order to avoid damage to the prefabricated building wall 600 during the subsequent door and window frame fixing process, the structure of the present application is used to complete the fixing of the door and window frames. First, the card seat 100 is docked with the card slot 500, and then the pusher 400 is adjusted so that the pusher 400 can support the door frame assembly engaged in the door and window opening; after the support is completed, the gap between the door frame and the wall is filled with foam glue, and then the door and window opening is wrapped and decorated with the door frame edge, completing the assembly of the prefabricated building door and window frame;

[0040] As a preferred implementation in this embodiment, an open sliding opening is provided on one side of the base 120, and the abutting block 200 extends from the sliding opening into the sliding area 130; a limiting plate 210 is provided on the abutting block 200 to prevent the abutting block 200 from slipping out of the sliding opening;

[0041] The base 120 is provided with a spring connection seat 150. One end of the spring 140 is connected to the spring connection seat 150, and the other end is connected to the push column 220. In the absence of external force, the spring 140 provides a pulling force to make the supporting block 200 close to the base 120.

[0042] As a preferred implementation in this embodiment, the push plate 410 includes a wedge block and a back plate, the push column 220 includes a variable diameter push block and a guide column, the spring 140 is nested around the guide column and connected to the variable diameter push block, and the wedge block is in contact with the side wall of the variable diameter push block; when the wedge block presses against the push column 220, the inclined surface structure of the wedge block pushes the variable diameter push block away from the base 120, so that the push plate 410 is moved forward by rotating the screw 420;

[0043] The back plate is provided with a bearing seat, and the front end of the screw 420 is assembled in the bearing seat. When the screw 420 rotates, the back plate will move linearly with the help of the bearing seat without rotating with the screw 420;

[0044] The screw hole support 430 is arranged in the sliding area 130, and a slide 440 is further provided between the screw hole support 430 and the spring connection seat 150. The back plate is provided with a guide groove adapted to the slide 440; during the pushing process, the guide groove helps the pushing plate 410 to be positioned and guided;

[0045] As a preferred implementation in this embodiment, a shielding cover 300 is further provided on the outside of the card slot 500; the structure of the shielding cover 300 is similar to that of the card base 100, and a pull rod is provided on the shielding cover 300. Here, the shielding cover 300 is mainly used to protect the card base 100 during the transportation of the assembled building to prevent damage to the card base 100;

[0046] The working principle of the present application is as follows: During the assembly construction process, a slot 500 is pre-set on the wall 600. The slot 500 is made of metal material, and the shielding cover 300 will first protect the slot 500. After the transportation process is completed, the shielding cover 300 is removed and the holder 100 is re-installed on the slot 500. Then, the distance between the supporting block 200 and the holder 100 is adjusted to ensure that the different supporting blocks 200 can provide sufficient support for the door and window frames.
