Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a keel structure and a wall structure of a modular building. Background Art

[0002] With people's pursuit of production efficiency and the development and progress of technology, modular buildings are increasingly used in the construction industry, and box-type modular buildings are one of the most widely used modular buildings.

[0003] In box-type modular buildings, the keel structure is an important wall component, which can be combined with the gypsum board wall to form the wall structure of the box-type modular building. After the box-type modular building is assembled, hidden decoration is required in the wall to allow the electrical pipelines to pass through the keel structure.

[0004] However, the current practice of concealed wall decoration is that electricians use a hole opener to open a wire hole at the location where the wire passes through the keel structure, and the electrical pipeline passes through the wire hole to pass through the keel structure. However, there are metal sharp edges around the wire hole during the hole opening process. When the electrical pipeline passes through the wire hole, the metal sharp edges will damage the outer skin of the pipeline, causing the outer skin of the pipeline to be damaged and leak electricity.

[0005] In the related art, in case of sharp metal edges on the keel structure, a wire protection cover is generally installed on the wire hole to cover the sharp metal edges and protect the electrical pipelines. However, there is a certain probability that the wire protection cover will fall off the keel structure, resulting in the electrical pipelines being cut by the sharp metal edges during later use, which poses a safety hazard to the electrical pipelines. In addition, the installation of the wire protection cover requires a certain amount of man-hours, and the decoration efficiency is low. Utility Model Content

[0035] See also Figures 1 to 6The present application provides a keel 100 structure, which includes: a keel 100; the keel 100 includes an inlet side wall 110 and an outlet side wall 130, the inlet side wall 110 is provided with a wire hole 111 for the electrical pipeline 60 to enter, and the outlet side wall 130 is provided with an outlet for the electrical pipeline 60 to pass out; wherein, a plurality of protective plates 120 are arranged on the inlet side wall 110; one end of the protective plate 120 is connected to the inlet side wall 110, and the connection point is located at the inner peripheral wall of the wire hole 111; the other end of the protective plate 120 extends toward the outlet side wall 130.

[0036] A hole 111 is punched on the inlet side wall 110 of the keel 100, and a plurality of protective plates 120 are provided on the periphery of the inlet side wall 110 and the periphery of ...

[0037] Figure 7 This is a second structural schematic diagram of the protection plate of the utility model.

[0038] See also Figures 5 to 7 In this embodiment, the inlet side wall 110 and the outlet side wall 130 of the keel 100 are relatively arranged so that the wire hole 111 of the inlet side wall 110 is relatively arranged with the outlet, and the electrical pipeline 60 passes through the keel 100 in a straight line, thereby facilitating the wiring of the electrical pipeline 60, thereby improving the assembly efficiency of the wall structure.

[0039] The keel 100 further includes at least two connecting walls 140, and at least one connecting wall 140 is respectively disposed on both sides of the inlet side wall 110 and the outlet side wall 130 to respectively connect the inlet side wall 110 and the outlet side wall 130. The inlet side wall 110 and the outlet side wall 130 are disposed opposite to each other.

[0040] In the direction from the incoming side wall 110 to the outgoing side wall 130 , the length of the protection plate 120 is less than the length of the connecting wall 140 , so that the incoming side wall 110 , the outgoing side wall 130 and the connecting wall 140 can protect the protection plate 120 , thereby improving the safety performance of the keel 100 .

[0041] See also Figures 5 to 7In this embodiment, the wire hole 111 is circular, elliptical or polygonal to meet various different hole opening requirements. In some embodiments, the wire hole 111 is polygonal, and the connection between two adjacent sides of the polygon is an arc transition to further improve the safety performance of the wire hole 111. This prevents the appearance of metal sharp edges at the intersection of two adjacent sides of the wire hole 111.

[0042] In some embodiments, a plurality of protection plates 120 are arranged around the periphery of the wire hole 111 so that the peripheral side walls of the wire hole 111 are all connected to the protection plates 120 , thereby preventing metal sharp edges from appearing on the peripheral side walls of the wire hole 111 .

[0043] In other embodiments, a preset area is provided on the inlet side wall 110, and the preset area on the inlet side wall 110 is cut and punched, so that the inlet side wall 110 in the preset area is bent to form a protection plate 120, so as to prevent the wire hole 111 of the inlet side wall 110 from generating metal sharp edges during the cutting process. When the electrical pipeline 60 passes through the wire hole 111, the contact surface between the electrical pipeline 60 and the protection plate 120 is smooth, and the electrical pipeline 60 passes through the keel 100 under the guidance of the protection plate 120, without causing the metal sharp edges to contact the surrounding side wall of the wire hole 111, so as to protect the safety of the electrical pipeline 60.

[0044] The provision of the protection plate 120 can also reduce the installation of wire protectors such as rubber rings and electrical bushings, thereby effectively reducing the production and processing steps of the keel 100 and reducing the production cost of the keel 100.

[0045] In some embodiments, the wire-entry side wall 110 and the protection plate 120 are integrally formed, thereby reducing the connection process between the protection plate 120 and the wire-entry side wall 110 and improving the production efficiency of opening the wire hole 111 on the wire-entry side wall 110 and connecting the protection plate 120, thereby reducing the production time and production cost of the keel 100.

[0046] See also Figures 5 to 7 In this embodiment, the protection plate 120 includes a connecting portion 121 and an extending portion 122. One end of the connecting portion 121 is connected to the incoming wire side wall 110 at the inner peripheral wall of the wire hole 111, and the connecting portion 121 transitions to the incoming wire side wall 110 in an arc shape. In the direction from the incoming wire side wall 110 to the outgoing wire side wall 130, the connecting portion 121 extends in an arc shape toward the center of the wire hole 111, and the other end of the connecting portion 121 is connected to the extending portion 122; the extending portion 122 extends toward the outgoing wire side wall 130.

[0047] When the connecting portion 121 is bent and extended in an arc shape toward the center of the wire hole 111, when the electrical pipeline 60 passes through the wire hole 111, under the action of the connecting portion 121, the electrical pipeline 60 can be offset toward the center of the wire hole 111 to move away from the inner wall of the wire hole 111, thereby further preventing the sharp metal edges on the inner wall of the wire hole 111 from damaging the electrical pipeline 60.

[0048] In some embodiments, due to the influence of the cutting process, when the wire side wall 110 is cut into the preset area, some sharp metal edges still exist at the cut between the two adjacent protective plates 120, and the connecting portion 121 connected to the inner wall of the wire hole 111 can make the electrical pipeline 60 away from the sharp metal edges at the intersection of the two protective portions, thereby improving the safety performance and reliability of the electrical pipeline 60.

[0049] See also Figures 5 to 7 In this embodiment, the extension portion 122 extends from the connection portion 121 toward the outlet side wall 130 to guide the electrical pipeline 60. When the electrical pipeline 60 passes through the keel 100, the electrical pipeline 60 can pass through the outlet side wall 130 under the guidance of the connection portion 121 and the extension portion 122. In addition, when a plurality of wire holes 111 are provided in the wall structure, the extension portion 122 can guide the electrical pipeline 60 to extend toward the wire hole 111 of the next keel 100, thereby improving the installation efficiency of the electrical pipeline 60.

[0050] In some embodiments, the protection plate 120 further includes a bent portion 123, which is connected to an end of the extension portion 122 away from the connection portion 121. In the direction from the incoming line side wall 110 to the outgoing line side wall 130, the bent portion 123 extends in a direction away from the wire hole 111, and the bent portion 123 transitions with the extension portion 122 in an arc shape. In other embodiments, the bent portion 123 is extended in an arc shape.

[0051] The setting of the bending portion 123 on the protection plate 120 can bend the end of the protection plate 120 away from the wire hole 111. When there is a metal sharp edge on the end of the protection plate 120 facing the wire outlet side wall 130, the metal sharp edge on the end of the protection plate 120 facing the wire outlet side wall 130 can be prevented from damaging the electrical pipeline 60, thereby ensuring the safety performance of the electrical pipeline 60.

[0052] In a plane perpendicular to the direction from the incoming line side wall 110 to the outgoing line side wall 130, the distance from the projection of the extension portion 122 to the center of the wire hole 111 is smaller than the distance from the projection of the connecting portion 121 and the bending portion 123 to the center of the wire hole 111, so that when the electrical pipeline 60 passes through the keel 100, the extension portion 122 can support and guide the electrical pipeline 60 and can effectively prevent the influence of the sharp metal edges on the electrical pipeline 60.

[0053] In some embodiments, the connecting portion 121, the extending portion 122 and the bending portion 123 are arranged in an arc shape in the direction from the incoming side wall 110 to the outgoing side wall 130. After the protection plate 120 is cut, the protection plate 120 is easily formed without the need for special processing of the shape of the protection plate 120, thereby effectively improving the production efficiency of the keel 100.

[0054] In some embodiments, on the projection plane perpendicular to the inlet side wall 110, the projection length of the extension portion 122 on the same protective plate 120 is greater than the projection length of the bending portion 123 and the connecting portion 121. The longer extension portion 122 can improve the guiding effect of the extension portion 122 on the electrical pipeline 60, so that the electrical pipeline 60 can pass through the keel 100 safely, stably and quickly. In addition, the longer extension portion 122 can also guide the electrical pipeline 60 to extend toward the subsequent wire holes 111, thereby improving the accuracy of the electrical pipeline 60 passing through multiple wire holes 111 and increasing the production efficiency of the wall structure.

[0055] See also Figures 5 to 7 In this embodiment, an outlet is opened on the outlet side wall 130, and the electrical pipeline 60 passes through the wire hole 111 to enter the keel 100, and then passes through the outlet to pass through the keel 100.

[0056] In some embodiments, in a plane perpendicular to the direction from the inlet side wall 110 to the outlet side wall 130, the diameter of the outlet is larger than the diameter of the wire hole 111. This facilitates the electrical pipeline 60 to enter the next keel 100 or other components without contacting the inner peripheral wall of the outlet under the guidance of the extension portion 122, thereby ensuring the safety of the wire hole 111 passing through the outlet.

[0057] In this embodiment, the keel 100 includes an inlet side wall 110, an outlet side wall 130, and two connecting walls 140, and the inlet side wall 110, the outlet side wall 130, and the two connecting walls 140 all extend vertically. In a plane perpendicular to the vertical direction, the inlet side wall 110 and the outlet side wall 130 are arranged opposite to each other, and the connecting wall 140 connects one side of the inlet side wall 110 and one side of the outlet side wall 130, so that the inlet side wall, the outlet side wall 130, and the two connecting walls 140 are rectangular.

[0058] In some embodiments, the opening 131 extends vertically to pass through both ends of the outlet side wall 130 in the vertical direction. In other embodiments, the inlet side wall 110, the outlet side wall 130 and the two connecting walls 140 are all formed by stamping and bending the same plate, and the two side walls of the plate are bent to form the two side walls of the outlet. On the one hand, the structural strength of the keel 100 can be improved, and on the other hand, the production process and working hours of the keel 100 can be reduced, thereby reducing the production cost.

[0059] In other embodiments, the inlet side wall 110 and the outlet side wall 130 are disposed adjacent to each other so that the path between the wire hole 111 and the outlet is bent. In some embodiments, the protection plate 120 is bent to guide and bend the electrical pipeline 60 so that the electrical pipeline 60 passes through the keel 100 toward the adjacent outlet.

[0060] See also Figures 1 to 7 In this embodiment, the inlet side wall 110 of the keel 100 is first cut and punched to form a plurality of protective plates 120, and the plurality of protective plates 120 are bent toward the outlet side wall 130. When the electrical pipeline 60 passes through the keel 100, first, the electrical pipeline 60 moves toward the wire hole 111, and the electrical pipeline 60 is introduced into the wire hole 111 under the action of the connecting portion 121. Afterwards, the electrical pipeline 60 moves toward the outlet under the action of the extension portion 122. Finally, the electrical pipeline 60 passes through the outlet and can be inserted into the subsequent keel 100 or other electrical components under the guidance of the extension portion 122.

[0061] The provision of the protection plate 120 can prevent the electrical pipeline 60 from contacting the sharp metal edge around the wire hole 111 when the electrical pipeline 60 passes through the wire hole 111, thereby effectively protecting the safety and reliability of the electrical pipeline 60. In addition, the provision of the protection plate 120 can also play a good guiding effect, improve the installation efficiency of the electrical pipeline 60, and reduce production costs.

[0062] In the present application, during the production process of the keel 100, a wire hole 111 is formed by punching on the wire entry side wall 110 of the keel 100. In addition, a plurality of protective plates 120 are provided on the wire entry side wall 110 around the wire hole 111. After the protective plate 120 is connected to the wire entry side wall 110 around the wire hole 111, it extends toward the wire exit side wall 130. The provision of the protective plate 120 can effectively prevent the appearance of sharp metal edges around the wire hole 111. So that the electrical pipeline 60 can safely and stably pass through the wire hole 111 and the outlet under the action of the protective plate 120, thereby effectively improving the safety of the keel 100 and preventing the electrical pipeline 60 from being damaged during movement.

[0063] See also Figures 1 to 7 The present application also provides a modular building wall structure, which includes a plurality of keels 100. The wire holes 111, the protection plates 120 and the outlets in the plurality of keels 100 form a wire passage 40, and the wire passage 40 is used for the electrical pipeline 60 to pass through; the wire passage 40 is in a straight line or arc shape.

[0064] When the wall structure is in the production process, the wire holes 111 are pre-opened on some of the keels 100, and then some of the keels 100 are arranged and connected in order, so that the wire holes 111, the protection plate 120, and the outlet on some of the keels 100 form a wire passage 40, and the wire passage 40 is used for the passage of the electrical pipeline 60. This effectively improves the installation efficiency of the electrical pipeline 60, and can ensure the safety of the electrical pipeline 60 when passing through the wire passage 40, and prevent it from being damaged by the metal sharp edge produced during the processing of the keel 100, thereby improving the assembly and production efficiency of the wall structure.

[0065] In some embodiments, the incoming line side wall 110 and the outgoing line side wall 130 on the keel 100 are respectively located on both sides of the keel 100 in the horizontal direction, so as to facilitate the formation of the wire passage 40 and also facilitate the passage of the electrical pipeline 60 through the keel 100 .

[0066] In this embodiment, the wall structure further includes a mounting frame 200, which extends in the horizontal direction. A plurality of keels 100 are respectively arranged on the mounting frame 200, and the plurality of keels 100 extend in the vertical direction, and the plurality of keels 100 are arranged in the horizontal direction. One end of the plurality of keels 100 is connected and limited to the mounting frame 200, thereby ensuring the stability and reliability of the wall structure.

[0067] In some embodiments, the wall structure includes two mounting frames 200, both of which extend in the transverse direction and are spaced apart from each other. A plurality of keels 100 are located between the two mounting frames 200, and both ends of the plurality of keels 100 are respectively connected and limited to the two mounting frames 200.

[0068] In some embodiments, after the keel 100 is produced, it is assembled with the mounting frame 200. In addition, since the wire holes 111 on the keel 100 have been pre-punched, and the plurality of wire holes 111 and the protective plate 120 form a wire passage 40, the laying process of the electrical pipeline 60 is more efficient than the traditional wiring process.

[0069] In some embodiments, the keel 100 extends in the transverse direction, and a plurality of keels 100 are arranged at intervals in the vertical direction. In other embodiments, a plurality of keels 100 are arranged in a staggered manner.

[0070] In some embodiments, the structure of the mounting frame 200 is similar to that of the keel 100 , and the electrical pipeline 60 can extend out of the wall structure through the wire hole 111 , the protection plate 120 and the opening 131 on the mounting frame 200 .

[0071] In this embodiment, the wall structure also includes a filler and an outer wall panel (not shown in the figure), and the filler is filled between two adjacent keels 100 to improve the thermal insulation performance and structural strength of the wall. The outer wall panel covers the sides of the keel 100 and the mounting frame 200 to protect the keel 100, the mounting frame 200 and the filler.

[0072] In this embodiment, the modular building also includes at least two concealed bottom boxes 300, which are respectively arranged on both sides of the wire passage 40. One end of the electrical pipeline 60 is connected to a concealed bottom box 300, and the other end of the electrical pipeline 60 passes through the wire passage 40 and is connected to the other concealed bottom box 300, so that an electrical socket is provided on the wall structure.

[0073] In some embodiments, the concealed bottom box 300 is connected to and limited to the keel 100, the filling piece or the outer wall panel.

[0074] The wall structure of the modular building of the present application can reduce the use of wire protectors and the process of installing wire protectors while meeting the protection function required for wiring of the electrical pipeline 60, thereby saving production and assembly time and improving work efficiency. In addition, by pre-punching the keel 100, the process of installing the keel 100 is effectively reduced, further embodying the design concept of modular buildings and improving installation efficiency.

[0075] Although the present application has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present application can be implemented in a variety of forms without departing from the spirit or essence of the utility model, it should be understood that the above-mentioned embodiments are not limited to any of the aforementioned details, but should be widely interpreted within the spirit and scope defined by the attached claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the attached claims.
