Description

Technical Field

[0001] This utility model belongs to the technical field of prefabricated building mold devices, specifically relating to a combined door and window frame mold for prefabricated buildings. Background Technology

[0002] In recent years, prefabricated buildings have been widely used due to their advantages such as high construction efficiency and good environmental performance. Among them, the three-dimensional mold system (vertical mold system) can realize the one-time casting of multiple walls or columns through combined molds, which significantly improves production efficiency.

[0003] In recent years, prefabricated buildings have been widely used due to their advantages such as high construction efficiency and good environmental performance. Among them, the three-dimensional mold system (vertical mold system) can realize the one-time casting of multiple walls or columns through combined molds, which significantly improves production efficiency. On prefabricated wall or house components, some walls need to leave windows or door openings. When dismantling the mold, it is necessary to remove the mold from the window or door opening. In particular, since the windows are closed on all sides, if they are removed along the direction perpendicular to the wall, the friction between the mold and the wall may damage the window. Although the patent application publication number CN 107116670 A discloses a window opening combination mold for prefabricated components, the demolding of this solution is relatively cumbersome. At the same time, when dealing with windows or door openings of different sizes, a lot of accessories need to be prepared, which cannot well adapt to the casting of windows or door openings of different sizes.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] The numbers in the diagram represent the following: 1 is a corner piece, 2 is the first connecting piece, 3 is the second connecting piece, 4 is a fixing bolt, 5 is an L-shaped template, 6 is a reinforcing plate, 7 is an oblique connecting plate, 8 is a connecting hole, 9 is a straight template, and 10 is a vertical connecting plate.

[0022] The following describes exemplary embodiments of this utility model in conjunction with specific circumstances:

[0023] like Figures 1 to 5 As shown, this utility model provides a modular door and window frame mold for prefabricated buildings, including corner pieces 1, straight pieces, and fixing bolts 4. Four corner pieces are set at the four top corners, and then first connecting pieces 2 and second connecting pieces 3 are connected in sequence between the four corner pieces, so that corner pieces 1, first connecting pieces 2, and second connecting pieces 3 form a door and window frame structure; corner pieces 1 are connected to first connecting pieces 2 and second connecting pieces 3 by inclined connecting plates 7, which facilitates later demolding.

[0024] The straight component includes 4N first connecting parts (2) or 2M second connecting parts (3), where M and N are integers, N≥0, M≥0; for example, Figure 1 The structure shown is a vertically supported window frame with M=2 and N=1; there are four corner pieces 1, located at the four corners of the door and window frame.

[0025] The straight component includes a straight template 9, a reinforcing plate 6 connected to the inside of the straight template 9, an oblique connecting plate 7 connected to at least one end of the straight template 9, and a vertical connecting plate 10 connected to at most one end of the straight template 9. Specifically: the straight template 9, the reinforcing plate 6 connected to the inside of the straight template 9, the oblique connecting plate 7 connected to one end of the straight template 9, and the vertical connecting plate 10 connected to the other end of the straight template constitute a first connecting component 2; the straight template 9, the reinforcing plate 6 connected to the inside of the straight template 9, and the oblique connecting plates 7 connected to both ends of the straight template 9 constitute a second connecting component 3; the straight component also includes a third connecting component, which includes the straight template 9, the reinforcing plate 6 located inside the straight template 9, and the vertical connecting plates 10 connected to both ends of the straight template 9 combined together to form the third connecting component. The third connecting component can serve as an extension component. When facing larger sizes, it can be extended by connecting the vertical connecting plate 10 of the first connecting component to meet the construction requirements of larger door and window frames.

[0026] The corner component 1 includes an L-shaped template 5, a reinforcing plate 6 disposed inside the L-shaped template 5, and inclined connecting plates 7 disposed at both ends of the L-shaped template 5. Connecting holes 8 for installing fixing bolts 4 are provided on the inclined connecting plates 7 and the vertical connecting plates 10. The inclined connecting plates 7 disposed on the connector are matched with the inclined connecting plates 7 on the corner component 1.

[0027] In this embodiment, the lengths of the first connector 2, the second connector 3, and the third connector range from 10 to 100 cm. Specifically, in a set of molds, the first connector 2, the second connector 3, and the third connector of different lengths can be set up and used in combination to meet the construction requirements of door and window frames of different widths and heights. In addition, this design of the first connector 2, the second connector 3, and the third connector can avoid the problem that the size of a single connector is too large and inconvenient to move and construct. Combining the three connectors can effectively reduce the number of connectors to be prepared.

[0028] In this embodiment, without considering the size of the corner piece 1, the lengths of the first connector, the second connector, and the third connector are any lengths of 10cm, 20cm, 30cm, 40cm, 50cm, or 80cm.

[0029] Usage: As needed for the required size of the door and window frame, take the corner piece, the first connector, the second connector, and the third connector, and then use fixing bolts to assemble them together to form the door and window frame. Place it in the position of the door and window frame in the casting mold. After the casting is completed and the wall has solidified, demolding is carried out. Unscrew the fixing bolts connecting the first connector and the corner piece, and then use the connection advantage of the inclined connecting plate to quickly remove the corner piece and connector to complete the demolding work.

[0030] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
