Description

Technical Field

[0001] This utility model relates to the field of building door and window technology, specifically to a prefabricated building door and window. Background Technology

[0002] Building doors and windows are an important part of buildings, with main functions including lighting, ventilation, shading, and insulation. They not only affect the appearance and function of buildings, but also play a key role in indoor light regulation, air circulation, and energy efficiency. With the development of the construction industry, prefabricated buildings have been widely used due to their advantages such as high efficiency and environmental protection.

[0003] The dimensions of conventional building doors and windows are fixed, and even a slight deviation in precision can affect installation. Moreover, the installation process is quite complicated, requiring a lot of on-site measurement, cutting, and splicing. This not only increases the workload of construction workers but also reduces the overall construction efficiency. Therefore, there is a need for prefabricated building doors and windows that can be finely adjusted in size and are easier to install. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a prefabricated building door and window, which has the advantages of being able to finely adjust the size of the building door and window and being relatively easy to install. It solves the problems that the size of general building doors and windows is fixed, and even a slight deviation in precision will affect the installation. Moreover, the installation process is relatively cumbersome, requiring a lot of on-site measurement, cutting, splicing and other work, which not only increases the workload of construction workers but also reduces the overall construction efficiency.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated building door and window, including a building wall, wherein a placement groove is provided inside the building wall, a bottom fixing frame is provided inside the placement groove, side fixing frames are fixedly connected to both sides of the bottom fixing frame, a first adjusting frame is movably engaged inside the side fixing frame, a top fixing frame is fixedly connected between opposite sides of the side fixing frame, a second adjusting frame is movably engaged inside the top fixing frame, and a first fixing bolt is threadedly connected inside both the side fixing frame and the top fixing frame.

[0008] Preferably, the bottom of the bottom fixing frame, the opposite side of the side fixing frame, and the top of the top fixing frame are all fixedly connected to connecting blocks. The interior of the building wall is provided with an installation groove, and a limiting block is fixedly connected inside the installation groove. The outer surface of the connecting block is adapted to the interior of the installation groove and the interior of the limiting block, respectively. The interior of the building wall is provided with a fixing groove, and a second fixing bolt is threadedly connected inside the fixing groove. The outer surface of the second fixing bolt is threadedly connected to the interior of the connecting block.

[0009] Preferably, both the first and second adjustment frames have connecting grooves inside, and a handle is fixedly installed inside the connecting groove. Using the handle in the connecting groove can help construction personnel move the adjustment frame more conveniently.

[0010] Preferably, a sealing cover is movably installed on the outer surface of the building wall via a hinge plate. The outer surface of the sealing cover is adapted to the inside of the fixing groove. After the building doors and windows are fixed, the sealing cover is put on, which not only avoids the unsightly exposed bolts but also reduces the speed of bolt corrosion and minimizes the impact on disassembly.

[0011] Preferably, a glass is provided between the opposite sides of the bottom fixing frame, the side fixing frame and the top fixing frame, and the glass is fixedly installed between the bottom fixing frame, the side fixing frame and the top fixing frame.

[0012] Compared with the prior art, this utility model provides a prefabricated building door and window, which has the following beneficial effects:

[0013] 1. Traditional building doors and windows suffer from installation problems even with slight deviations in precision, and the installation process is cumbersome, increasing the workload of construction workers and reducing overall construction efficiency. This utility model design places the fixed frame with the glass installed into the placement groove, and pulls the first adjusting frame and the second fixed frame to their maximum positions, so that the building door and window are adjusted to fit the placement groove perfectly, avoiding the situation where installation is impossible due to slight deviations in size. After the two adjusting frames are moved, the connecting blocks on them enter the installation groove and fit into the limiting block. At this time, the second fixing bolt is used to fix it and the installation is completed.

[0014] 2. The doors and windows of this building integrate the functions of fine adjustment of door and window size and convenient installation. The doors and windows of this building have connecting grooves in the side fixing brackets and top fixing brackets. The pull handles in the connecting grooves can be used to move the adjustment brackets more conveniently. The doors and windows of this building have sealing covers installed on each fixing groove by hinges. After the doors and windows of this building are fixed, the sealing covers are closed, which not only avoids the unsightly exposed bolts, but also reduces the speed of bolt corrosion and minimizes the impact on disassembly.
