Description

Technical Field

[0001] This utility model relates to the field of prefabricated buildings, and in particular to windows specifically designed for prefabricated buildings. Background Technology

[0002] Patent document CN 219953360 U discloses a pre-embedded window frame structure for prefabricated concrete buildings. Paragraph

[0032] discloses that a pad 4 and a fixing block 6 are fixedly connected to the outer side of a first frame 1. Anchor holes 7 are provided on the fixing block 6, and anchor bars 8 are disposed within the anchor holes 7. The anchor holes 7 and anchor bars 8 are threadedly connected. To prevent the installed anchor bars 8 from bending due to accidental stress during transportation, the operators transport the anchor bars 8 and the window frame body separately at the factory. Only after transportation to the site are the anchor bars 8 threadedly installed into the anchor holes 7 of the window frame body. While this avoids deformation of the anchor bars 8 during transportation, transporting the anchor bars 8 separately occupies additional transportation space. Utility Model Content

[0003] The present invention aims to provide a special window for prefabricated buildings, whose anchor bars are not prone to accidental bending during transportation and do not require additional transportation space.

[0004] A prefabricated window for prefabricated buildings includes a window frame body. Multiple first threaded holes are formed on the four outer side walls of the window frame body (top, bottom, left, and right). Each first threaded hole has a prefabricated base, and multiple first anchor bars are fixed to the front of the prefabricated base. Each prefabricated base has a through hole aligned with the first threaded hole. Threaded anchor bars with threads on their outer side walls pass through the through holes and are then threaded into the first threaded holes. Nuts are installed on the threaded anchor bars to lock the back of the prefabricated base to the outer side wall of the window frame body. Second and third threaded holes are formed on the inner bottom wall of the window frame body for threaded installation of the threaded anchor bars on the prefabricated bases. Multiple horizontal drainage channels are formed at the bottom of the window frame body, with the front of each channel extending to the front side wall of the window frame body and the rear connecting to the bottom of the second threaded holes.

[0005] Furthermore, grooves are provided on the four outer side walls of the window frame body (top, bottom, left, and right), and the first threaded hole is provided on the bottom of the groove, into which the prefabricated base is inserted.

[0006] Furthermore, the drainage channel slopes downwards at a 2° angle from back to front.

[0007] Furthermore, there are eight first threaded holes, and a total of eight second and third threaded holes.

[0008] Furthermore, the window frame body is used to install sliding windows.

[0009] The beneficial effects are as follows: During transportation, operators place multiple prefabricated bases onto the second and third threaded holes respectively. Then, multiple threaded anchor bars are passed through the through holes of the corresponding prefabricated bases and threaded into the corresponding second and third threaded holes. Nuts are then installed on the threaded anchor bars to lock the back of the prefabricated bases to the bottom wall of the window frame body. In this way, the prefabricated bases are temporarily installed in the window frame body, utilizing the unused space within the window frame body to transport the prefabricated bases and anchor bars. The anchor bars are less likely to be accidentally bent during transportation and do not require separate transport, thus eliminating the need for additional transport space. For pre-installation, remove the nuts, threaded anchor bars, and prefabricated bases. Place multiple prefabricated bases at the corresponding positions on the four outer walls of the window frame body (top, bottom, left, and right). Pass each threaded anchor bar through the through hole of its corresponding prefabricated base and then thread it into the first threaded hole. Install nuts on the threaded anchor bars to lock the back of the prefabricated base to the outer wall of the window frame body. The window frame body is now in the pre-installation state and can be installed into the window opening of the prefabricated building. After installation, the second and third threaded holes serve as drainage inlets for the window frame body. Attached Figure Description

[0015] The present invention will be further described in detail below with reference to specific embodiments.

[0016] like Figure 1 and Figure 3 As shown, six second threaded holes 9 and two third threaded holes 4 are provided on the inner bottom wall of the window frame body 1. Figure 4As shown, eight prefabricated concrete bases 6 are placed above the second threaded holes 9 and third threaded holes 4, respectively. Multiple vertical first anchor bars 7 are installed on the top wall (front) of each prefabricated base 6. Each prefabricated base 6 has a through hole in its center (obscured in the figure). Eight threaded anchor bars 8, with threads on their outer walls, pass through the eight through holes and are then threaded into six second threaded holes 9 and two third threaded holes 4, respectively. Nuts are installed on each threaded anchor bar 8 to lock the back of the prefabricated base 6 to the inner bottom wall of the window frame body 1. This temporarily installs the prefabricated base 6 inside the window frame body 1, utilizing the unused space within the window frame body 1 to transport the prefabricated base 6 and anchor bars. This prevents the anchor bars from being accidentally bent during transport and eliminates the need for separate transport, thus avoiding additional transport space requirements. At this time, the window frame body 1 is in transport mode.

[0017] like Figure 1 As shown, eight grooves 2 are respectively opened on the four outer side walls of the window frame body 1 (top, bottom, left, and right), and each groove 2 has a first threaded hole 3 at its bottom. After the window frame body 1, which is in transport condition, is transported to the construction site, the operators remove the nuts, eight threaded anchor bars 8, and eight prefabricated bases 6, thereby restoring the window frame body 1 to its original state. Figure 1 The original state is shown. Then, as shown... Figure 2 As shown, multiple prefabricated bases 6 are placed at corresponding positions on the four outer walls of the window frame body 1 (top, bottom, left, and right). Multiple threaded anchor bars 8 are then passed through the through holes of the corresponding prefabricated bases 6 and threaded into the first threaded holes 3. Nuts are then fitted onto the threaded anchor bars 8 to lock the back of the prefabricated bases 6 to the outer walls of the window frame body 1. The window frame body 1 is now in a pre-embedded installation state, installed into the window opening of the prefabricated building. Concrete is then poured between the inner wall of the window opening and the outer wall of the window frame body 1, embedding the first anchor bars 7 and threaded anchor bars 8 within the concrete. This completes the installation of the window frame body 1.

[0018] like Figure 3 As shown, the bottom of the window frame body 1 has multiple horizontal drainage channels 5 extending forward and backward. The front of each drainage channel 5 extends to the outside of the front side wall of the window frame body 1, and the rear of each drainage channel 5 connects to the bottom of the second threaded hole 9. A three-way channel 10 connects the third threaded hole 4 and the second threaded hole 9. The drainage channels 5 slope downward at 2° from back to front. The operator installs a first track (not shown in the figure) in front of the second threaded hole 9 on the inner bottom wall of the window frame body 1, and a second track (not shown in the figure) behind the third threaded hole on the inner bottom wall of the window frame body 1. Two sliding windows (not shown in the figure) are then installed on the first and second tracks respectively. Rainwater falls onto the sliding windows and flows down along them to the space between the first and second tracks. It then flows through the six second threaded holes 9 and the two third threaded holes 4 into the three-way channel 10 and the drainage channels 5 respectively, and is then discharged through the front end of the drainage channel 5.

[0019] The above description is merely an embodiment of this utility model and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on this utility model will still fall within the scope of patent protection.
