Technical Field

[0002] The utility model relates to the technical field of assembled buildings, in particular to a pre-buried wire box, a pre-buried wire box assembly and a hollow thin shell wall. Background Art

[0003] In prefabricated buildings, the wire box inner box of traditional prefabricated concrete solid walls is generally embedded in the wall at one time together with the wire pipe before concrete pouring. For hollow thin-shell walls, the wire box and the pipeline need to be placed in the concrete pouring before embedding. This method will affect the production efficiency of hollow thin-shell walls, resulting in a decrease in the production efficiency of hollow thin-shell walls. Utility Model Content

[0004] The purpose of the utility model is to solve the problem of affecting production efficiency when installing wire boxes and pipelines in hollow thin shell walls. The utility model provides a pre-buried wire box, which can effectively shorten the total production time of hollow thin shell walls with integrated wire boxes and pipelines, thereby improving production efficiency.

[0005] In order to solve the above technical problems, the inventors have explored and found that the existing method of installing wire boxes and pipelines in hollow thin-shell walls will lead to a decrease in the production efficiency of hollow thin-shell walls. The reason is that since the hollow thin-shell walls are composed of two wall panels and a cavity between the two wall panels, it is necessary to put the wire boxes and pipelines into the mold for making the wall panels before pouring the wall panels, and then pour the concrete of the wall panels to achieve the installation of the wire boxes and pipelines. However, this method will cause the production process of hollow thin-shell walls to be more complicated. First of all, it is necessary to carry out the positioning and laying out of the pre-embedded wire boxes and pipelines and the positioning, installation and fixing of the wire boxes and pipelines in advance, which will increase the production time of hollow thin-shell walls. For production on the assembly line, it will have a certain impact on the production rhythm. Moreover, the pre-embedded wire boxes and wire pipes will affect the removal of some accessories in the demoulding link of the middle wall panel, thereby further affecting the work efficiency.

[0006] The pre-buried wire box provided by the utility model includes a mother box and a male box. Before the production and pouring of the hollow thin shell wall, the mother box is first positioned and installed. The thickness of the side span of the mother box is not greater than the thickness of the wallboard. When pouring the concrete of the wallboard, the mother box is pre-buried in the wallboard, so that an installation port is formed on the wallboard. Since the edges of the mother box will not exceed the wall surface of the wallboard, it is more convenient to demould the wallboard and will not be interfered by the mother box. After the wallboard is demoulded, the male box and the wire tube are installed. The male box can be inserted into the female box and reliably fixed with the female box. The wire tube can be inserted from the cavity between the two wallboards and docked with the male box, so that the installation of the male box and the wire tube can be placed later, which can effectively shorten the total production time of the hollow thin shell wall with integrated wire boxes and pipelines, and is easy to install, thereby effectively improving production efficiency.

[0047] The following is an explanation of the implementation of the present invention by specific specific embodiments. Those skilled in the art can easily understand other advantages and functions of the present invention from the contents disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this utility model are limited to this implementation. On the contrary, the purpose of introducing the utility model in conjunction with the implementation is to cover other options or modifications that may be extended based on the claims of the present invention. In order to provide a deep understanding of the present invention, the following description will include many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description. It should be noted that, in the absence of conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0048] It should be noted that in this specification, similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0049] The terms “first”, “second”, “third”, “fourth”, etc. are merely used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0050] In the description of this embodiment, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connected", and "connected" 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 or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0051] In prefabricated buildings, the wire box inner box of traditional prefabricated concrete solid walls is generally embedded in the wall at one time together with the wire pipe before concrete pouring. For hollow thin-shell walls, the wire box and the pipeline need to be placed in the concrete pouring before embedding. This method will affect the production efficiency of hollow thin-shell walls, resulting in a decrease in the production efficiency of hollow thin-shell walls.

[0052] To solve the above technical problems, the inventors have discovered that the existing method of installing a wire box and a pipeline in a hollow thin shell wall will reduce the production efficiency of the hollow thin shell wall. The reason is that the hollow thin shell wall is composed of two wall panels 3 and a cavity 4 located between the two wall panels. Fig.11As shown, it is necessary to put the wire box and pipeline into the mold for making the wall panel 3 before pouring the wall panel 3, and then pour the concrete of the wall panel 3 to realize the installation of the wire box and pipeline, but this method will make the production process of the hollow thin shell wall more complicated. First of all, it is necessary to carry out the positioning and laying out of the pre-buried wire boxes and pipelines and the positioning, installation and fixing of the wire boxes and pipelines in advance, which will increase the production time of the hollow thin shell walls. For production on the assembly line, it will have a certain impact on the production rhythm. Moreover, the pre-buried wire boxes and wire pipes will affect the removal of some accessories in the demoulding link of the middle wall panel 3, thereby further affecting the work efficiency.

[0053] refer to Figure 1 and Fig.11 The pre-buried wire box provided by the utility model includes a female box 1 and a male box 2. Before the production and pouring of the hollow thin shell wall, the female box 1 is first positioned and installed. The thickness of the side span of the female box 1 is not greater than the thickness of the wallboard. When pouring the concrete of the wallboard 3, the female box 1 is pre-buried in the wallboard 3, so that an installation opening 11 is formed on the wallboard 3. Since the edges of the female box 1 will not exceed the wall surface of the wallboard 3, it is more convenient to remove the mold of the wallboard 3 and will not be interfered by the female box 1. After the wallboard 3 is demoulded, the male box 2 and the wire tube are installed. The male box 2 can be inserted into the installation opening 11 and reliably fixed with the female box 1. The wire tube can be inserted from the cavity 4 between the two wallboards 3 and docked with the male box 2, so that the installation of the male box 2 and the wire tube can be placed later, which can effectively shorten the total production time of the hollow thin shell wall with integrated wire boxes and pipelines, and the installation is convenient, thereby effectively improving the production efficiency.

[0054] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0055] refer to Figure 1 , Figure 2 and Figure 5 The embodiment of the utility model discloses a pre-buried wire box, including a mother box 1 and a male box 2, wherein the mother box 1 is provided with an installation port 11, the male box 2 includes a box body 21 and a connecting portion 29, the box body 21 has an inner cavity 22, and the outer wall of the box body 21 is provided with a threading groove 23, the connecting portion 29 is detachably connected to the mother box 1, and when the connecting portion 29 is connected to the mother box 1, the box body 21 is inserted into the installation port 11.

[0056] For example, in this embodiment, the mother box 1 is a rectangular frame, and the mother box 1 has a first end face 161 and a second end face 162. The first end face 161 and the second end face 162 are located in the through direction of the mother box 1 (such as Figure 6The first end face 161 and the second end face 162 are parallel to each other, and the installation opening 11 passes through the first end face 161 and the second end face 162 of the female box 1. The installation opening 11 is a rectangular opening. However, the present application does not limit the shape of the female box 1, and any structure that can be plugged into the male box 2 belongs to the protection scope of the present application.

[0057] Exemplarily, the box body 21 is a rectangular parallelepiped, which includes four side panels 27 and a bottom panel 28. The inner wall of each side panel and the inner wall of the bottom panel 28 together form an inner cavity 22. A plurality of wire threading grooves 23 may be provided on the same box body 21. The wire threading grooves 23 may be circular (the shape of the circular wire threading grooves 23 is only used to explain the present application, and is not used to limit the present application. All equivalent implementations or changes that do not deviate from the present invention should be included in the scope of the present application). The diameters of each wire threading groove 23 may be the same or different. The wire threading groove 23 is a connection port for the wire pipe. Its specific arrangement position should avoid the steel bars 5 and the wall panels 3 in the wall, so that the wire pipe will not be blocked by the steel bars 5 or the wall panels 3, and can be smoothly connected to the male box 2. In this embodiment, four wire threading grooves 23 are provided on each side panel 27 of the box body 21, and two wire threading grooves 23 are provided on the bottom panel 28 of the box body 21. Figure 3 , Figure 4 shown.

[0058] By adopting the above technical solution, the pre-buried wire box is configured as a female box 1 and a male box 2, and the male box 2 and the female box 1 are detachably connected. When pouring the concrete of the wall panel 3, the female box 1 can be pre-buried in the wall panel 3 (refer to Fig.11 ), so that the female box 1 and the wall panel 3 become a whole, and then the male box 2 is inserted into the installation port 11 from the outside of the wall panel 3, so that the box body 21 passes through the installation port 11 and extends into the cavity 4, and the male box 2 is fixed on the female box 1, and then the wire tube is installed and docked with the male box 2, so that the installation of the male box 2 and the wire tube can be postponed, which can effectively shorten the total production time of the hollow thin shell wall with integrated wire boxes and pipelines, and the installation is convenient, thereby effectively improving the production efficiency.

[0059] Furthermore, the threading groove 23 is a through groove connected to the inner cavity 22, or a groove not connected to the inner cavity 22, and the groove can be connected to the inner cavity 22 under the action of external force.

[0060] By adopting the above technical solution, when the wire threading groove 23 is a groove spaced apart from the inner cavity 22, the wire threading groove 23 is not connected to the inner cavity 22. If the wire threading groove 23 is not needed temporarily in actual use, the wire threading groove 23 is not connected to the inner cavity 22 to prevent dust from entering the inner cavity 22; if the wire tube needs to be inserted into the wire threading groove 23 in actual use, it is only necessary to chisel off the bottom of the wire threading groove 23 and apply force to the groove to make it connected to the inner cavity 22, which is convenient for use.

[0061] Further, such as Figure 5 , Figure 7 As shown, a first slot 12 is provided on the inner wall of the mounting opening 11. Figure 2 , Figure 3 As shown, a first card block 24 is provided on the outer wall of the box body 21. When the connecting portion 29 is connected to the female box 1, the first card block 24 is inserted into the first card slot 12 to achieve a detachable connection. By providing the first card slot 12 and the first card block 24, the tightness of the connection between the male box 2 and the female box 1 can be enhanced to avoid looseness. The utility model does not limit the specific shapes of the first card slot 12 and the first card block 24. All equivalent implementations or changes that do not deviate from the utility model should be included in the scope of this application.

[0062] Further, a fastener is also included, the female box 1 is provided with a first mounting hole 13, and the connecting portion 29 is provided with a second mounting hole 25. When the box body 21 is inserted into the mounting port 11, the axes of the first mounting hole 13 and the second mounting hole 25 coincide, and the fastener is provided in the first mounting hole 13 and the second mounting hole 25 to fix the male box 2 to the female box 1. Exemplarily, the fastener can be a self-tapping screw, which passes through the second mounting hole 25 and taps the first mounting hole 13 to fix the connecting portion 29 to the female box 1. In this embodiment, the number of the first mounting hole 13 and the second mounting hole 25 are both four, and each first mounting hole 13 is respectively provided at the four corners of the first end surface 161.

[0063] For further information, see Figures 5 to 8 The mother box 1 has a first side surface 163, a second side surface 164, a third side surface 165 and a fourth side surface 166 which are perpendicular to the first end surface 161, wherein the first side surface 163 is parallel to the second side surface 164, the third side surface 165 is parallel to the fourth side surface 166, and the first side surface 163 is perpendicular to the third side surface 165. A second card slot 14 is provided on the first side surface 163, and a second card block 15 is provided on the second side surface 164, and the second card slot 14 is adapted to the shape of the second card block 15. By providing the second card block 15 and the second card slot 14, the second card block 15 of one mother box 1 can be inserted into the second card slot 14 of another mother box 1, so that multiple mother boxes 1 can be connected, and multiple pre-buried wire boxes can be connected in sequence, such as Fig. 9 The present invention does not limit the specific shapes of the second card slot 14 and the second card block 15, and any equivalent implementation or modification that does not deviate from the present invention should be included in the scope of this application.

[0064] Furthermore, protrusions 26 are provided on the third side 165 and the fourth side 166. When the wall panel 3 is poured with concrete, the protrusions 26 are embedded in the wall panel 3 of the hollow thin shell wall, thereby increasing the anchoring force between the mother box 1 and the wall panel 3. The utility model does not limit the specific shape of the protrusions 26, which can be square, prototype, arc or any polygon. In this embodiment, six protrusions 26 are provided on each of the third side 165 and the fourth side 166, and the protrusions 26 on the same side are arranged at equal intervals.

[0065] refer to Fig. 9 , Fig.10 The embodiment of the utility model also discloses a pre-buried wire box assembly, comprising at least two of any of the aforementioned pre-buried wire boxes, each of which is arranged in sequence along a straight line direction, and two adjacent mother boxes 1 are detachably connected through a second card slot 14 and a second card block 15.

[0066] By adopting the above technical solution, by connecting multiple pre-buried wire boxes in sequence and making the connection between two adjacent mother boxes 1 detachable, the number of pre-buried wire boxes can be increased or decreased according to actual needs on site, thereby making the application more flexible.

[0067] refer to Fig.11 The embodiment of the utility model also discloses a hollow thin shell wall, including two walls along a first direction (such as Fig.11 The wall panels 3 are arranged at intervals (in the X direction shown in the figure), and there is a cavity 4 between the two wall panels 3. The thin shell wall also includes any of the above-mentioned embedded wire boxes, or any of the above-mentioned embedded wire box components. Among them, the female box 1 is embedded in the wall panel 3, and the installation opening 11 passes through the female box 1 along the first direction. The size of the female box 1 along the first direction is less than or equal to the thickness of the wall panel 3. When the male box 2 is connected to the female box 1, the box body 21 is inserted from the outside of the wall panel 3 into the installation opening 11 (the insertion direction of the box body 21 is as shown in the figure). Fig.11 The inner cavity 22 is connected with the cavity 4 through the threading groove 23.

[0068] By adopting the above technical solution, by setting the aforementioned embedded wire box in the hollow thin shell wall, when pouring the concrete of the wall panel 3, the mother box 1 can be embedded in the wall panel 3 first, so that the mother box 1 and the wall panel 3 become a whole. Since the size of the mother box 1 along the first direction is less than or equal to the thickness of the wall panel 3, the edges of the mother box 1 will not exceed the wall surface of the wall panel 3, so the wall panel 3 will be more convenient to demould and will not be interfered by the mother box 1. After the wall panel 3 is demoulded, the male box 2 is subsequently inserted into the installation port 11 of the female box 1 for fixing. The wire tube can be inserted from the cavity 4 between the two wall panels 3 and docked with the male box 2, so that the installation of the male box 2 and the wire tube can be postponed, which can effectively shorten the total production time of the hollow thin shell wall with integrated wire box and pipelines, and the installation is convenient, thereby effectively improving the production efficiency.

[0069] Furthermore, a steel bar 5 is provided in the cavity 4 to enhance the strength of the hollow thin shell wall.
