Description

Technical Field

[0001] The utility model belongs to the technical field of pipe gallery brackets, and in particular relates to an aluminum alloy bracket component used for a pipe gallery. Background Art

[0002] The pipe gallery is a corridor that integrates electricity, communications, gas, drainage, etc., which is convenient for unified planning, design, construction and management. Generally, in order to save space, the cables or pipes in the pipe gallery are in the air and supported by brackets, so the brackets of the pipe gallery need to have good bearing capacity to support the construction of the pipe gallery. Traditional brackets are usually made of steel, but such brackets have many problems, such as high processing costs, heavy weight of the finished brackets leading to difficulty in installation, short service life, etc.

[0003] With the in-depth study of aluminum alloy materials, it is found that compared with carbon steel profiles, due to the addition of alloy components, aluminum alloy materials not only have better plasticity, easy processing and forming, better corrosion resistance, and extend the service life of the bracket, but also have higher hardness and strength, and aluminum profiles are lighter (only one-third of steel); on the other hand, compared with carbon steel profiles, aluminum alloy profiles have more surface treatment methods, such as sandblasting, polishing, anodizing, coloring, electrophoresis, spraying, etc. Therefore, more and more application scenarios use aluminum alloy materials to replace carbon steel as brackets. For example, among them, the Chinese invention patent with publication number CN114542805A discloses a finished bracket made of aluminum alloy, which is a bracket system that is directly produced by the factory with shaped profiles and various connectors, and then handed over to the construction personnel for on-site assembly. This bracket system can be used to support various types of pipes and pipelines, which is of great significance in indoor installation of buildings. When the finished bracket is assembled, the brackets need to be connected to each other. Specifically, the finished bracket adopts multiple closed structure brackets and mounting components for connecting the brackets, wherein the bracket includes two first side walls arranged opposite to each other and two second side walls arranged opposite to each other, the two first side walls and the two second side walls enclose the closed structure, and at least one first connecting portion is provided on the first side wall and / or the second side wall; the bracket in this solution is fixed with redesigned self-tapping screws and connectors with high load-bearing capacity and shear resistance, which effectively ensures the high load-bearing capacity of the support bracket as a whole.

[0004] However, the above-mentioned finished brackets are usually used in scenarios where the indoor installation of the brackets has high requirements on the bearing capacity of the brackets. As for the brackets used in underground pipe corridors, since their bearing capacity requirements are relatively low, if the above-mentioned brackets are used, it will inevitably lead to a situation of "wasting the material for a larger purpose".

[0005] For this purpose, the prior art proposes an aluminum alloy bracket for pipe corridors. For example, the Chinese invention patent with publication number CN116526406A discloses an aluminum alloy cable bracket for pipe corridors, including an embedded channel steel and a bracket arm, a connector is provided between the embedded channel steel and the bracket arm, one connector is provided above and one connector is provided below the bracket arm, the connector is connected to the embedded channel steel and the bracket arm by T-bolts, the T-bolts are locked with locking nuts, the bracket arm is arranged horizontally, the embedded channel steel has a steel anchor on the back, and the embedded channel steel is provided with a folding ear parallel to the notch at the notch.

[0006] However, on the one hand, the installation of the above bracket is relatively complicated. For example, it is necessary to install connectors on the upper and lower sides of the bracket respectively, and then fix them with special T-shaped bolts. On the other hand, the above bracket is a channel steel with teeth. When the tube bundle is installed on it, the teeth and the plane of the tube bundle base are easy to slide relative to each other. In addition, the spacing between the tube bundles is not easy to control. Utility Model Content

[0007] The purpose of the utility model is to provide an aluminum alloy bracket assembly for a pipe gallery, so as to partially alleviate at least one of the above-mentioned problems, thereby improving the stability of the pipe gallery bracket assembly.

[0008] In order to solve the technical problems mentioned above, the utility model specifically adopts the following technical solutions: an aluminum alloy bracket assembly for a pipe gallery, comprising a base and a bracket arm, wherein the bracket arm is divided into a supporting area for supporting and a connecting area for fastening to the base from its first end to its second end; the supporting area comprises a first area with a concave cross-section arranged sequentially from top to bottom, and two second areas integrally formed with two side walls of the first area, respectively, the first area extends in a horizontal direction, and the cross-sectional area of ​​the second area gradually decreases from its second end to the first end, forming a supporting structure for supporting the first area; the cross-section of the connecting area is rectangular, and its two oppositely arranged side walls are respectively provided with at least one second mounting hole;

[0009] The base is provided with a through slot for mounting the bracket arm, and two side walls of the base arranged opposite to each other are respectively provided with at least one first mounting hole matching the second mounting hole;

[0010] When the bracket is mounted on the base, the second end of the connection area extends into the through slot, and the fixing member passes through the first mounting hole and the second mounting hole in sequence to fix the two;

[0011] The first surface of the first area is sunken to form a first groove, and at least two third mounting holes are evenly arranged in the first groove. Two adjacent third mounting holes form a mounting structure for mounting a tube bundle.

[0012] As an improvement, the first region includes a horizontal portion extending in the horizontal direction, and two side edges in the length direction of the horizontal portion extend in the vertical direction to form vertical portions; the two vertical portions continue to extend in the vertical direction to form two second regions in a triangular shape.

[0013] As an improvement, the middle parts of the four side walls of the connecting area are respectively recessed inward to form a first recessed portion, a second recessed portion, a third recessed portion and a fourth recessed portion, and the thicknesses of the first recessed portion, the second recessed portion, the third recessed portion and the fourth recessed portion are respectively smaller than the thicknesses of the connecting portions on both sides thereof; the first recessed portion is connected to the first groove and are in the same plane, and the second recessed portion and the fourth recessed portion are respectively connected to the two second areas and are located in the same vertical plane.

[0014] As an improvement, the second mounting holes are arranged on the connecting portions on both sides of the second recessed portion and the fourth recessed portion.

[0015] As an improvement, the fixing member is a self-tapping screw.

[0016] As an improvement, the fixing member is a bolt that can penetrate two first mounting holes that are arranged opposite to each other on both sides of the base.

[0017] As an improvement, the support arm is formed by cutting a square tube with a symmetrical structure and a rectangular cross section into two parts in the first direction, the second direction and the third direction in sequence.

[0018] As an improvement, the third mounting hole is a rectangular mounting hole arranged along the length direction of the support arm.

[0019] As an improvement, it further comprises a tube bundle mounting seat, the tube bundle mounting seat comprising a main seat body matched with the mounting structure, and a sub-seat body matched with the cable or the pipe, the sub-seat body is fixed to the main seat body by bolts, the main seat body is provided with two through holes, and the through holes correspond to the third mounting holes;

[0020] When the main seat body is installed on the bracket arm, the bolt passes through the through hole and the third mounting hole in sequence to fix the two.

[0021] As an improvement, the through hole is a non-enclosed through hole, and the opening of the through hole can allow a bolt to pass through.

[0022] The principle and beneficial effects of the utility model are:

[0023] The bracket assembly in the present application is provided with a support area with a bottom opening and a concave cross section on the support arm, and its connecting end is connected to a connecting area with a rectangular cross section, so that when the tube bundle is installed on the support area, a conventional long bolt can be directly inserted through the tube bundle mounting seat and the long hole on the upper surface of the support area, and then the nut can be screwed on the other end of the long bolt from the bottom opening of the support area, so that there is no need to use a special T-bolt to install the tube bundle as in the prior art (CN116526406A), which not only makes the installation process simpler and more convenient, but also reduces the cost to a certain extent without the need to prepare special bolts. In addition, since the support area and the connecting area adopt an integrated molding process, compared with the prior art (CN116526406A) that uses a reinforcing rib to connect two C-shaped grooves with opposite openings and teeth, not only the manufacturing process is simpler, but also the structure is simpler.

[0024] In addition, in the prior art, since the teeth are provided and the support arm is only fixed longitudinally, when the cable or pipeline above the support arm is dragged, the friction between the teeth and the outer wall of the cable or pipeline will cause the support arm to move in the horizontal direction (for example, left and right), that is, to move horizontally along with the cable or pipeline, thereby loosening the bolts fixed longitudinally. In the present application, since the support arm is fixed in the base in an inserted manner, the two side walls of the base have a blocking effect on the support arm in the horizontal direction, which can effectively prevent the support arm from shaking left and right under the drive of the cable or pipeline when the cable or pipeline above the support arm is dragged, thereby causing the problem of bolt loosening; at the same time, by providing equidistant long holes on the support arm, the spacing between cables (or pipelines) and cables (or pipelines) is more controllable and easier to locate, thereby making installation more convenient and ensuring the installation stability of the cable or pipeline.

[0025] Furthermore, the present solution adopts cutting (for example, laser cutting) to divide the one-piece columnar square tube into two to obtain two support arms, thereby achieving full utilization of materials while meeting the bearing capacity requirements of the support arms in the pipe gallery, thereby greatly saving costs; while in the prior art (invention patent with publication number CN116526406A), the support arm is a first channel steel and a second channel steel fixedly connected by a plate-shaped reinforcing rib plate to form a special-shaped structure. On the one hand, the one-piece molding strength of the present solution will be reduced, and on the other hand, its manufacturing process is more complicated, thereby increasing the cost.

[0026] Furthermore, different areas of the support arm are set to different thicknesses. For example, the thickness of the parts with lower strength requirements (such as the second area and the recessed parts) is set to be thinner, and the thickness of the parts with higher strength requirements (such as the connecting area and the docking part of the base, that is, the connecting parts on both sides of the recessed parts) is set to be thicker, which can further save materials without affecting the bearing capacity of the support arm.

DETAILED DESCRIPTION

[0047] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0048] Herein, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present invention, and have no specific meanings. Therefore, "module", "component" or "unit" can be used in a mixed manner.

[0049] In this document, the terms "upper", "lower", "inner", "outer", "front", "rear", "one end", "the other end" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0050] In this document, unless otherwise clearly specified or limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection 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 utility model can be understood according to specific circumstances.

[0051] Herein "and / or" includes any and all combinations of one or more of the associated listed items.

[0052] Herein, "plurality" means two or more than two, ie, it includes two, three, four, five, etc.

[0053] like Figure 1 As shown, the utility model provides an aluminum alloy bracket assembly for a pipe gallery, comprising a base 2 and a support arm 1, wherein the base 1 and the support arm 2 are fixed by fixing parts, wherein the base 1 is fixed on a wall in the pipe gallery, and the upper surface of the support arm 2 is used to place and fix cables or pipes in the pipe gallery.

[0054] Compared with the existing metal support arms, the bracket assembly in this solution is made of non-magnetic aluminum alloy and will not generate eddy currents.

[0055] like Figure 2a-2d The support arm is divided into a bearing area and a connecting area 13 from its first end to the second end; the bearing area includes a first area 11 with a concave cross-section (a cross-section formed by cutting along the height direction of the support arm) arranged in sequence from top to bottom, and two second areas 12 integrally formed with the two side walls of the first area 11, respectively. The first area 11 extends in a horizontal direction (that is, it is arranged along the length direction of the support arm), and the cross-sectional area of ​​the second area 12 gradually decreases from the second end to the first end, forming a supporting structure 121 for supporting the first area 11.

[0056] When arranging cables or pipes in the pipe gallery, they are usually arranged in a vertical serpentine manner (i.e., multiple cables or pipes are arranged in parallel in the vertical direction through multiple parallel support arms) or in a horizontal serpentine manner (i.e., multiple cables or pipes are arranged in parallel on the same support arm). When vertical serpentine laying is adopted, the pipe bundle is laid starting from the side of the support arm close to the wall or close to the base, and the free end of the support arm (i.e., the end away from the base) is usually not provided with cables (or pipes), so the bearing capacity requirement for the free end of the support arm is relatively low. Therefore, this scheme adopts an aluminum alloy bracket assembly to support the pipe, and its bearing capacity is sufficient to meet the bearing capacity requirement in the pipe gallery, and compared with the columnar support arm, it saves materials.

[0057] In this article, the first end refers to the end of the support arm that is away from the base and is not connected to any component, that is, the free end in this article; the second end refers to the end close to the base, or close to the wall after installation; accordingly, since the main function of the load-bearing area is to carry cables or pipes, the connecting area is used to connect the support arm and the base.

[0058] like Figure 3a-Figure 3b The base is provided with a through slot 22 for mounting the bracket, and at least one first mounting hole 21 is respectively provided on the two side walls of the base; accordingly, Figure 2c The cross section of the connection area (the cross section formed by cutting along the height direction of the bracket arm) is rectangular, and the two opposite side walls thereof are respectively provided with at least one second mounting hole 131; when the bracket arm is mounted on the base, the second end of the connection area extends into the through groove 22, and the fixing member passes through the first mounting hole and the second mounting hole in sequence to fix the two; the structure after fixing is as shown in FIG. Figure 1 shown.

[0059] In some embodiments, Figure 3d At least one fourth mounting hole is also provided on the base. When in use, a connecting piece or a fixing piece (such as an expansion screw) is passed through the fourth mounting hole and driven into the wall of the pipe gallery to fix it to the wall in the pipe gallery.

[0060] In some embodiments, the fixing member is a long bolt that can penetrate two first mounting holes that are arranged opposite to each other on both sides of the base. Figure 3a-Figure 3b The first mounting holes may be provided in two groups, one of which is a round hole matched with a long bolt, and the other is an oblong hole, in which the long bolt can slide up and down to adjust its position.

[0061] In other embodiments, the fixing member is a self-tapping screw. Figure 3e , the first mounting hole is a round hole that matches the self-tapping screw, such as Figure 6Self-tapping screws, also known as self-drilling self-tapping screws, refer to a screw with a drill bit or a cutter head. Through the construction of special power tools, it can be penetrated and fixed in the corresponding first mounting hole and second mounting hole on one side of the base mentioned in this article.

[0062] If the base and the support arm are connected by bolts that penetrate the mounting holes on both sides of the base, there will always be a certain gap between the bolts and the mounting holes, which provides space for the support arm to shake and the fixing effect is poor. Self-tapping screws can also be used in this solution. There is almost no gap between the screws and the mounting holes, which makes the connection between the base and the support arm more secure.

[0063] In some embodiments, the first area 11 includes a horizontal portion extending along the axial direction of the support arm, and the two side edges in the length direction of the horizontal portion extend in the vertical direction to form vertical portions; the two vertical portions continue to extend in the vertical direction to form two second areas in a triangular shape; the connecting area 13 is a columnar structure surrounded on all sides, and the middle parts of the four side walls of the connecting area 13 are respectively recessed inward to form a first recessed portion 132, a second recessed portion 133, a third recessed portion 134 and a fourth recessed portion 135 in sequence, and the thicknesses of the first recessed portion 132, the second recessed portion 133, the third recessed portion 134 and the fourth recessed portion 135 are respectively smaller than the thicknesses of the connecting portions on both sides thereof, so that the two connecting portions between two adjacent side walls on adjacent connecting areas form an "L"-shaped reinforcement structure with a thickness greater than the recessed portion; the first recessed portion 132 is connected to the first groove and is in the same horizontal plane, and the second recessed portion 133 and the fourth recessed portion 135 are respectively connected to the two second areas and are in the same vertical plane.

[0064] The horizontal direction in this article refers to the length direction or axial direction of the support arm, and the vertical direction refers to the height direction of the support arm.

[0065] In some embodiments, the second mounting hole is arranged on the connecting portion on both sides of the second recessed portion 133 and the fourth recessed portion 135, that is, the second mounting hole is arranged on the raised portion of the side wall of the connecting area, so as to facilitate the fixation of the support arm and the base and ensure the fixing strength.

[0066] In some embodiments, the thickness of the first groove and the second area are both smaller than the thickness of the vertical portion and the connecting portion for connecting the first groove and the vertical portion; and the thickness of the first groove is the same as the first recessed portion, and the thickness of the vertical portion is the same as the thickness of the connecting portion of the connecting area.

[0067] By designing different parts of the support arm to have different thicknesses, for example, setting the part with higher bearing capacity requirements (such as the connecting part) to be thicker and setting the remaining parts to be thinner, it is possible to further save materials without affecting the fixing strength of the support arm.

[0068] The first surface of the first area (i.e., the side used to install cables or pipes) is recessed to form a first groove, and at least two third installation holes are evenly arranged in the first groove, and two adjacent third installation holes form a mounting structure for installing cables or pipes.

[0069] In some embodiments, Figure 4a-4c The support arm is formed by cutting a square tube with a symmetrical structure and a rectangular cross section into two parts in the first direction, the second direction and the third direction in sequence, that is, a square tube can be cut into two identical support arms.

[0070] The first direction and the third direction are the same, both are the height direction of the bracket or square tube, and the second direction is Figure 4b The direction of the arrow is from the bottom of the square tube to its upper side.

[0071] In some embodiments, Figure 5a-5d As shown, the bracket assembly also includes a tube bundle mounting seat 3, which includes a main seat body that cooperates with the mounting structure, and a sub-seat body that cooperates with the cable or pipe, and the sub-seat body is fixed to the main seat body by bolts. Specifically, the main seat body is provided with at least two through holes, and the sub-seat body is also provided with two corresponding through holes. The bolts pass through the corresponding two through holes in sequence to fix the two. In addition, the sub-seat body is also provided with a groove for accommodating cables or pipes.

[0072] The bottom of the main seat body is also provided with two through holes, which correspond to the third mounting holes; when the main seat body is mounted on the bracket arm, bolts are passed through the through holes and the third mounting holes in sequence to fix the two. Since the through holes and the third mounting holes in this solution are both hollow designs, the bolts can be directly passed through the through holes and the third mounting holes, and then the nuts are screwed into the bolts from the bottom of the first mounting plate to fix them; while the bracket arm in the prior art adopts a groove with the opening of the groove facing upward, and it is inconvenient to install it with ordinary bolts, so only special T-shaped bolts can be used to fix the tube bundle on the bracket arm, that is, the tube bundle in this solution is more convenient to install than the prior art.

[0073] In some embodiments, the through hole is a non-closed through hole, that is, an opening is left on the side wall of the opening, and the opening corresponds to the third mounting hole, and the opening of the through hole can allow a bolt to pass through; correspondingly, the third mounting hole is a rectangular mounting hole arranged along the length direction of the support arm, so that the bolt can be first inserted from one side of the third mounting hole, and then slide along the length direction of the third mounting hole, so as to adjust the installation position of the tube bundle, and enter the through hole through the opening, and then be fixed, so that the installation of the tube bundle mounting seat can be more convenient.

[0074] The bracket assembly with the above structure has a simple structure and is easy to install. Only four conventional bolts are needed to install the cable (or pipe). In the prior art, if the cable (or pipe) is to be installed, two different bolts need to be prepared, one is a conventional bolt for connecting the cable (or pipe) to the tube bundle mounting seat, and the other is a T-bolt for connecting the tube bundle mounting seat to the bracket (such as a C-shaped channel steel).

[0075] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0076] The embodiments of the utility model are described above in conjunction with the accompanying drawings, but the utility model is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the utility model, ordinary technicians in this field can also make many forms without departing from the scope of protection of the utility model and the claims, which all fall within the protection of the utility model.
