DETAILED DESCRIPTION

[0040] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0041] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "top", "bottom", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying 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 of the present invention. It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, the "first" information may also be referred to as the "second" information, and similarly, the "second" information may also be referred to as the "first" information.

[0042] like Figures 1 to 10 As shown, a preferred embodiment of the door and window opening forming module of the present invention comprises a formwork body 1, a plurality of connecting members 2 and a plurality of embedded members 3, wherein the formwork body 1 is used to be arranged in a wall casting mold to separate door openings or window openings during the casting process of the wall 100; the connecting members 2 are arranged at intervals along the edge of the formwork body 1, the first end of each connecting member 2 is rotatably inserted in the formwork body 1, the second end of each connecting member 2 is extended to the outside of the formwork body 1 facing the wall 100, and the second end of each connecting member 2 is provided with an external thread, and each embedded member 3 is provided with a threaded hole 31, and the external thread of the second end of each connecting member 2 is matched and inserted in each threaded hole 31 one by one; thereby, the embedded member 3 is temporarily connected to the outside of the formwork body 1, and after the wall casting is completed, the embedded member 3 detached from the connecting member 2 is used to connect the door frame 200 or the window frame.

[0043] When in use, each embedded part 3 is first screwed with the connecting part 2 so that the embedded part 3 is attached to the outside of the formwork body 1; then after the wall 100 is poured, the embedded part 3 remains in the wall 100, and thereafter, the connecting part 2 is removed from the embedded part 3, and the door frame 200 or the window frame can be connected through the threaded hole 31 of the embedded part 3. Therefore, when the door and window openings constructed by the door and window opening forming module of the present invention are installed, it is not necessary to drill installation holes on the building main body when installing the door frame or window frame, thereby avoiding damage to the wall 100 caused by drilling holes.

[0044] If the threaded hole 31 is a through hole, during the pouring of the wall 100, concrete can easily flow into the threaded hole 31 through the opening of the threaded hole 31 at one end away from the connector 2, which has an adverse effect on the subsequent connection with the bolt. In this embodiment, in order to prevent concrete from flowing into the threaded hole 31 during the pouring of the wall 100, the threaded hole 31 is a blind hole with an internal thread, and the opening of the blind hole faces the formwork body 1.

[0045] In this embodiment, each of the connecting members 2 is a fastener, and the threaded end of each fastener passes through the formwork body 1 and is assembled in the threaded hole 31, and the end of the embedded member 3 facing the formwork body 1 abuts against the formwork body 1. The connecting member 2 is set as a fastener, and when the connecting member 2 and the embedded member 3 are assembled, the embedded member 3 can be pulled to move in a direction close to the formwork body 1 by rotating the fastener, so that the end of the embedded member 3 facing the formwork body 1 abuts against the formwork body 1, preventing concrete from entering the threaded hole 31 through the gap between the embedded member 3 and the formwork body 1 or adhering to the outside of the fastener, which facilitates the removal of the connecting member 2 and the embedded member 3 after the concrete solidifies.

[0046] In order to increase the pre-tightening torque of the bolts when installing the window frame or door frame 200, a rotation-stopping protrusion 32 is provided on the outer circumference of the embedded part 3 in this embodiment. Specifically, the embedded part 3 is a column, and the rotation-stopping protrusion 32 is at least one rib arranged around the circumference of the embedded part 3.

[0047] In this embodiment, each anti-rotation protrusion 32 is respectively arranged at one end of each embedded part 3 away from the formwork body 1. The anti-rotation protrusion 32 is arranged at one end of the embedded part 3 away from the formwork body 1, which can also improve the pull-out resistance of the embedded part 3, further improve the firm connection between the embedded part 3 and the wall 100, thereby ensuring the firm connection of the window frame or door frame 200.

[0048] In the present embodiment, the door and window opening forming module also includes an embedded part installation tool 4; the embedded part installation tool 4 is detachably connected to one side of the mold frame body 1, and a positioning hole 41 opposite to each fastener is provided in the embedded part installation tool 4, and the hole wall of each positioning hole 41 is provided with a limiting groove 42 for limiting the anti-rotation protrusion 32; each embedded part 3 is movably inserted in each positioning hole 41, and each fastener is rotated, and each fastener respectively pulls each embedded part 3 to move toward the mold frame body 1 until each fastener is abutted against the mold frame body 1.

[0049] Specifically, the formwork body 1 is a square frame or a door-shaped frame with an opening at the lower end. The formwork body 1 is composed of a vertical plate 11, a horizontal plate 12 and a plurality of adapters 13. The adapters 13 are arranged at the corners of the formwork body 1. To ensure the connection strength between the window frame or door frame 200 and the wall 100, in this embodiment, a plurality of mounting holes for inserting fasteners used as the connecting members 2 are arranged at length square intervals on the vertical plates 11 or the horizontal plates 12. When the embedded part installation tool 4 is connected to the transverse plate 12 or the vertical plate 11, each installation hole and each positioning hole 41 are arranged in a one-to-one correspondence. When the connecting part 2 and the embedded part 3 need to be assembled, each embedded part 3 is first inserted into each positioning hole 41 of the embedded part installation tool 4, and then the embedded part installation tool 4 and the vertical plate 11 or the transverse plate 12 are connected. Thereafter, the fastener serving as the connecting part 2 is passed through the installation hole, and the fastener is rotated. When the fastener is rotated, the embedded part 3 is constrained by the positioning hole 41 and cannot rotate, but can move axially along the positioning hole 41. Therefore, by rotating the fastener, each embedded part 3 can be quickly assembled on the outside of the fastener and the end of each embedded part 3 can be abutted against the vertical plate 11 or the transverse plate 12. To ensure accurate alignment of the embedded part installation tool 4 with the vertical plate 11 or the horizontal plate 12, in the present embodiment, the embedded part installation tool 4 is provided with a positioning groove 43, which is a through groove. The groove width of the positioning groove 43 matches the width of the vertical plate 11 or the horizontal plate 12, and the positioning hole 41 is arranged at the bottom of the groove of the positioning groove 43. When in use, one side of the formwork body 1 is inserted into the positioning groove 43. Specifically, the vertical plate 11 or the horizontal plate 12 is placed in the positioning groove 43 so that the embedded part installation tool 4 can be aligned with the vertical plate 11 or the horizontal plate 12 in the width square. After that, any connecting part 2 and the corresponding embedded part 3 can be connected to align the embedded part installation tool 4 with the vertical plate 11 or the horizontal plate 12 in the length square.
