[0043] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0044] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] The following describes in detail various embodiments of the present invention in conjunction with the accompanying drawings.

[0046] See also Figure 1 and Figure 2 The embodiment of the utility model provides a combined keel 100, comprising a support member 110 and an internal component 120. The support member 110 has a first end 110a and a second end 110b arranged opposite to each other and is provided with a filling hole 110c and a mounting hole 110d. The filling hole 110c penetrates the support member 110 in a direction from the first end 110a to the second end 110b, and the mounting hole 110d is provided in the support member 110 and communicates with the filling hole 110c. The internal component 120 is accommodated in the filling hole 110c and is connected to the support member 110 through a connecting member (not shown), and the strength of the internal component 120 is less than that of the support member 110. The external fixing member passes through the mounting hole 110d and is connected to the internal component 120 to fix the combined keel 100. Among them, the external fixing member can be a nail, and as a part of other building templates, the combined keel 100 and the building template where the external fixing member is located together form a casting model for casting the building main body.

[0047] See also Figure 2 In some embodiments, the mounting hole 110d includes a first through hole 110e and a second through hole 110f. The first through hole 110e is opened on one side of the support member 110 and connected to the filling hole 110c. The second through hole 110f is opened on a side of the support member 110 opposite to the first through hole 110e and connected to the filling hole 110c.

[0048] Therefore, the first through holes 110e and the second through holes 110f distributed on both sides of the support member 110 can enable the external fixing member to be connected to the internal member 120 from different angles, which is beneficial to improving the application range of the combined keel 100.

[0049] In some embodiments, there are multiple first through holes 110e and multiple second through holes 110f, and the multiple first through holes 110e and the multiple second through holes 110f are spaced apart along the direction from the first end 110a to the second end 110b, and the multiple first through holes 110e and the multiple second through holes 110f correspond to each other one by one, and are staggered in the direction perpendicular to the first end 110a to the second end 110b.

[0050] Therefore, the multiple first through holes 110e and the multiple second through holes 110f can provide multiple connection positions for external fixing members, which is beneficial to improving the application range of the combined keel 100.

[0051] In some embodiments, the connecting member is one of a rivet, a bolt, and a screw, which helps to reduce the cost of using the connecting member.

[0052] In some embodiments, the support member 110 is a steel member, and the internal member 120 is one of a wood-plastic member, a polyvinyl chloride member, and a polypropylene member.

[0053] Therefore, by properly configuring the materials of the support member 110 and the internal member 120 , the manufacturing cost of the combined keel 100 can be reduced while ensuring that the combined keel 100 has sufficient strength.

[0054] See also Figure 2 In some embodiments, the cross section of the support member 110 is a square or a rectangle. When the cross section of the support member 110 is a square, the stability of the support member 110 itself is stronger than when the cross section of the support member 110 is a rectangle. When the cross section of the support member 110 is a rectangle, the surface area of ​​the support member 110 is larger than when the cross section of the support member 110 is a square, which is conducive to reducing damage to components located on the support member 110.

[0055] In this embodiment, the support member 110 is a strip-shaped structure with a square cross section, and the direction from the first end 110 a to the second end 110 b is the length direction of the support member 110 .

[0056] In other embodiments, the cross-section of the support member 110 may also be a triangle or other polygons.

[0057] See also Figure 3 In some embodiments, the combined keel 100 further includes two stoppers 130. The two stoppers 130 are respectively held in the filling hole 110c, and one of the stoppers 130 is located at the first end 110a, and the other stopper 130 is located at the second end 110b. The two stoppers 130 are used to stop the built-in component 120.

[0058] Therefore, the two stoppers 130 located at both ends of the filling hole 110 c can improve the overall strength of the assembled keel 100 and prevent the built-in component 120 from escaping from the filling hole 110 c.

[0059] See also Figure 3 and Figure 4 In some embodiments, each stopper 130 includes a stopper body 131 and a plurality of toggle bodies 132. The plurality of toggle bodies 132 are connected end to end in sequence, and the plurality of toggle bodies 132 are all against the inner wall of the filling hole 110c, the stopper body 131 is located in the area surrounded by the plurality of toggle bodies 132 and is respectively connected to the plurality of toggle bodies 132, and the stopper body 131 is accommodated in the filling hole 110c. When the stopper 130 is assembled and placed in the filling hole 110c, the stopper body 131 can be driven to move by the toggle body 132.

[0060] Therefore, the ends of the plurality of shifting bodies 132 are connected, so that the stopper 130 can form a uniform support for the inner wall of the filling hole 110 c and help improve the efficiency of installing the stopper 130 in the filling hole 110 c.

[0061] In this embodiment, the number of the shifting bodies 132 is four, and the stopper 130 is a centrally symmetrical structure.

[0062] See also Figure 4 In some embodiments, each of the toggle bodies 132 is bent and extended in a direction away from the stop body 131 to form a toggle groove 132 a.

[0063] Therefore, through the above-mentioned arc-shaped structure, the force position of the shifting body 132 can be located in the middle of the filling hole 110 c, so that the operator or the transfer mechanism has enough movement space when connecting with the shifting body 132.

[0064] See also Figure 2 In some embodiments, the first through hole 110e and the second through hole 110f each include a square segment 110g and two arc segments 110h. The square segment 110g is connected to the filling hole 110c, and the two arc segments 110h are both connected to the filling hole 110c, and one of the arc segments 110h is located between the square segment 110g and the first end 110a, and the other arc segment 110h is located between the square segment 110g and the second end 110b.

[0065] Therefore, the four end corners of the first through hole 110e and the second through hole 110f are all arc-shaped structures, which can reduce the damage to the strength of the support member 110 and help the support member 110 meet the required strength.

[0066] When the above-mentioned combined keel 100 is used, the length and specific position of the built-in component 120 in the filling hole 110c can be determined based on different installation positions, such as: top plate, beam, wall column, structure inner corner, etc., to meet the installation requirements of different installation positions.

[0067] In the above-mentioned combined keel 100, the built-in component 120 and the support component 110 form a nested structure to ensure the strength of the combined keel 100. The built-in component 120 with relatively low strength is connected to the external fixing component to fix the combined keel 100, thereby realizing the connection and fixation of the combined keel 100 with other building formworks where the external fixing components are located, which is beneficial to reduce the degree of damage of the combined keel 100 after multiple disassembly and assembly, thereby increasing the service life of the combined keel 100.

[0068] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
