Description

Technical Field

[0001] This utility model relates to the field of support and hanger technology, and specifically to a prefabricated support and hanger. Background Technology

[0002] Pipe supports and hangers are commonly used support and suspension devices in industrial pipelines, building electromechanical equipment, and cable tray systems. They are mainly used to fix, bear weight, and adjust the spatial position of pipelines or equipment to ensure their stable operation. Compared with traditional pipe supports and hangers, prefabricated pipe supports and hangers are more standardized and modular. They achieve efficient installation through prefabrication and rapid on-site assembly, thereby improving the convenience of construction.

[0003] In existing technologies, conventional prefabricated hoisting supports mainly consist of vertically positioned columns and a crossbeam installed between two columns. Both the columns and the crossbeam are made of channel steel, and they are connected by connectors. One end of the connector is fixed to the column with bolts, while the other end is fixed to the end of the crossbeam via a channel steel locking clip. The connection is secured by the interlocking force of the channel steel and the small teeth of the locking clip. This connection method, where the crossbeam and channel steel locking clip are fixed by interlocking force, requires a high degree of fit and the teeth have limited load-bearing capacity, resulting in relatively unstable installation of the crossbeam and posing certain safety hazards. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated support bracket with lower installation requirements, more stable installation structure, and lower safety hazards to address the above problems.

[0005] This utility model is achieved using the following technical solution: a prefabricated support frame, comprising at least three vertically parallel support columns, characterized in that the support columns include two side columns located on both sides and several middle columns located between the two side columns, each of the two side columns is detachably mounted with an inward-facing "L"-shaped connector, and each of the several middle columns is detachably mounted with two outward-facing "L"-shaped connectors, the "L"-shaped connectors being able to be adjusted in position in the vertical direction; a crossbeam is provided between each two adjacent support columns, the crossbeam rests between the two "L"-shaped connectors, and the bottom of the crossbeam is fixedly connected to the "L"-shaped connector by bolts.

[0006] The above structure distributes the supporting force of the crossbeam to the "L"-shaped connectors on both sides. It is equivalent to the "L"-shaped connectors dragging the crossbeam. Compared with the channel steel lock, which pulls the crossbeam from above, the connection method adopted by this utility model is more stable, has a higher safety factor, does not involve the meshing of teeth, and has lower installation requirements.

[0007] Preferably, each supporting column is a channel steel composed of two side plates and a back plate. The "L"-shaped corner connectors include one corner connector installed on each supporting column and one back-hole connector installed on each central column. The two ends of the crossbeam can be detachably and fixedly connected to the two corner connectors or the corner connectors and back-hole connectors. The corner connectors and back-hole connectors provide support for the installation of the crossbeam.

[0008] Preferably, the corner connector includes two parallel "L"-shaped first connecting plates. The two first connecting plates are detachably and fixedly connected to the outer sides of the two side plates of the supporting column, respectively. A first support plate is fixedly connected between the two first connecting plates, located at the end of the first connecting plate furthest from its mounting point on the supporting column. The end of the crossbeam can rest on the first support plate and is detachably and fixedly connected to it. The two first connecting plates ensure a more secure installation of the corner connector on the supporting column, and the first support plate provides support for the installation of the crossbeam.

[0009] Preferably, the back-hole connector includes a second connecting plate that is detachably and fixedly connected to the back plate of the central column. The bottom of the second connecting plate extends away from the central column where it is installed to form a second support plate. The second support plate is perpendicular to the second connecting plate, and the end of the crossbeam can rest on and be fixedly connected to the second support plate. The second connecting plate allows the back-hole connector to be installed away from the corner connector, thereby supporting the crossbeam.

[0010] Preferably, both sides of the second support plate extend upward to form fixing plates, which are attached to both sides of the crossbeam. The fixing plates prevent the crossbeam from swaying back and forth, further improving the stability of the crossbeam connection.

[0011] Preferably, the side and back plates of the supporting column are each provided with a plurality of vertically evenly distributed first mounting holes, and the first connecting plate is provided with a plurality of second mounting holes. Bolts pass through the first and second mounting holes to detachably fix the supporting column to the corner connector. The second connecting plate is provided with a plurality of third mounting holes, and bolts pass through the third mounting holes and the first mounting holes to detachably fix the central column to the back hole connector. The cooperation of the first and second mounting holes allows the corner connector to move up and down on the supporting column to adjust its installation position. Similarly, the cooperation of the first and third mounting holes allows the back hole connector to move up and down on the central column to adjust its installation position.

[0012] Preferably, one of the side columns is hinged with an anti-seismic hinge. A support rod is fixedly connected to the end of the anti-seismic hinge furthest from the side column. A hinge sleeve is fixedly connected to the end of the support rod furthest from the anti-seismic hinge. A first mounting seat, fixedly connected to the wall, is hinged to the end of the hinge sleeve furthest from the support rod. By using the anti-seismic hinge and the inclined support rod, the load is prevented from being concentrated entirely on the support column, reducing the risk of localized damage and improving the overall structural stability.

[0013] Preferably, the seismic-resistant hinge includes a second bent plate hinged to the back plate of the mounting side column. A first bent plate is fixedly connected to the end of the second bent plate away from the back plate. A first hinge plate is fixedly connected to the end of the first bent plate away from the second bent plate. The first hinge plate is hinged to the second hinge plate. A third bent plate is fixedly connected to the end of the second hinge plate away from the first hinge plate. A fourth bent plate, fixedly connected to the support rod, is fixedly connected to the end of the third bent plate away from the second hinge plate. By installing the seismic-resistant hinge, some of the energy generated by the vibration of the supports and hangers can be absorbed, thereby ensuring the safety of the pipeline during vibration.

[0014] Preferably, both sides of the fourth bent plate extend upwards in a direction perpendicular to the fourth bent plate to form baffles, and the baffles are in contact with both sides of the support rod. The baffles make the connection between the fourth bent plate and the support rod more stable.

[0015] Preferably, the first support plate has a second fixing hole, the second support plate has a third fixing hole, and the bottom of the crossbeam has a first fixing hole. The first fixing hole is an elongated oval hole. Bolts pass through the first and second fixing holes, the first fixing hole, and the third fixing hole to detachably fix the crossbeam to the first and second support plates. Using bolts for connection prevents the crossbeam from moving up and down, improving the overall stability of the support frame.

[0016] In summary, the beneficial effects of this utility model are as follows: By using corner connectors and back-hole connectors, the crossbeam in this device is supported, and the contact between surfaces makes the force more stable, thereby making the overall support frame more stable and reducing safety hazards. Furthermore, since the crossbeam is supported, there is no need to use channel steel locks, i.e., no toothed engagement is required. During installation, simply place the crossbeam on the support plate and then fix it with bolts to prevent the crossbeam from moving up and down, making installation much more convenient.

Detailed Implementation

[0024] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0025] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0026] The following is a description of preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0027] like Figure 1As shown, this utility model provides a prefabricated support bracket, including at least three vertically parallel support columns. Each support column is further divided into two side columns 6 located on either side and a central column 28 located between the side columns 6. The tops of both the side columns 6 and the central column 28 are fixedly equipped with second mounting seats 5 for support. The support columns can be vertically installed on ceilings or other mounting surfaces via the mounting seats 5, thus providing support for overhead pipes in buildings. Each of the two side columns 6 has an inward-facing "L"-shaped connector detachably installed, and several central columns 28 have two outward-facing "L"-shaped connectors detachably installed. The "L"-shaped connectors can be adjusted vertically along the support columns to meet the different installation height requirements of various pipes. A crossbeam 8 for supporting the pipes is provided between adjacent support columns. The crossbeam 8 rests between the two "L"-shaped connectors. To prevent vertical vibration of the crossbeam 8, its bottom is fixedly connected to the "L"-shaped connectors with bolts.

[0028] All the supporting columns are channel steel composed of two side plates and one back plate. The "L"-shaped corner connectors include a corner connector 7 installed on each supporting column and a back hole connector 9 installed on each central column 28. The two ends of the crossbeam 8 can be detachably fixedly connected to the two corner connectors 7 or the corner connectors 7 and the back hole connectors 9.

[0029] The combination of two side panels and a back panel forms an open surface, that is, the surface opposite the back panel is an open surface, and the orientation of this open surface is the same as the orientation of the corner connector 7.

[0030] like Figure 1 , Figure 3 , Figure 4 As shown, the corner connector 7 includes two parallel "L"-shaped first connecting plates 14. The two first connecting plates 14 are detachably and fixedly connected to the outer sides of the two side plates of the support column, respectively. A first support plate 15 is fixedly connected between the two first connecting plates 14. The first support plate 15 is located at the end of the first connecting plate 14 furthest from where it is mounted on the support column, and is located at the bottommost end of the first connecting plate 14. The end of the crossbeam 8 can rest on the first support plate 15 and is detachably and fixedly connected to it. When the crossbeam 8 is installed on the corner connector 7, the two sides of the crossbeam 8 are in contact with the inner walls of the two first support plates 15, thereby preventing the crossbeam 8 from swaying axially along the pipe.

[0031] like Figure 1 , Figure 5As shown, the back hole connector 9 includes a second connecting plate 16 that is detachably and fixedly connected to the back plate of the central column 28. The bottom of the second connecting plate 16 extends away from the central column 28 to form a second support plate 17. The second support plate 17 is perpendicular to the second connecting plate 16. The end of the crossbeam 8 can rest on the second support plate 17 and is fixedly connected to the second support plate 17. Both sides of the second support plate 17 extend upward to form fixing plates 18. When the crossbeam 8 is installed on the back hole connector 9, both sides of the crossbeam 8 are in contact with the two inner walls of the fixing plates 18. This design is also to prevent the crossbeam 8 from swaying along the axial direction of the pipe, further improving the stability of the device.

[0032] like Figure 1 , Figure 4 , Figure 5 As shown, the detachable connections in this device are all achieved through the use of holes and bolts. Specifically, several vertically evenly distributed first mounting holes 10 are provided on the side plates and back plates of the supporting column, and several second mounting holes 12 are provided on the first connecting plate 14. The supporting column and the corner connector 7 are detachably fixedly connected by bolts passing through the first mounting holes 10 on the two side plates and the second mounting holes 12 on the two first connecting plates 14. Several third mounting holes 19 are provided on the second connecting plate 16. The central column 28 and the back hole connector 9 are detachably fixedly connected by bolts passing through the third mounting holes 19 and the first mounting holes 10 on the back plate of the central column 28.

[0033] This detachable connection method allows for the mass production of individual components, which can then be adjusted according to the actual usage conditions on site to adapt to different installation heights. This eliminates the need for customization based on height, resulting in good economic benefits and greater ease of operation.

[0034] like Figure 1 , Figure 6 As shown, an anti-seismic hinge 4 is hinged to one of the side columns 6. An inclined support rod 3 is fixedly connected to the end of the anti-seismic hinge 4 away from the side column 6. A hinge sleeve 2 is fixedly connected to the end of the support rod 3 away from the anti-seismic hinge 4. A first mounting base 1, which is fixedly connected to the wall, is hinged to the end of the hinge sleeve 2 away from the support rod 3.

[0035] The seismic-resistant hinge 4 includes a second bent plate 23 hinged to the back plate of its mounting side column 6. A first bent plate 22 is fixedly connected to the end of the second bent plate 23 away from the back plate. A first hinge plate 21 is fixedly connected to the end of the first bent plate 22 away from the second bent plate 23. A second hinge plate 24 is hinged to the first hinge plate 21. A third bent plate 25 is fixedly connected to the end of the second hinge plate 24 away from the first hinge plate 21. A fourth bent plate 26, fixedly connected to the support rod 3, is fixedly connected to the end of the third bent plate 25 away from the second hinge plate 24. Both sides of the fourth bent plate 26 extend upwards in a direction perpendicular to the fourth bent plate 26 to form baffles 27, which are in contact with both sides of the support rod 3.

[0036] By installing the seismic hinge 4 and the inclined support rod 3, an inclined force-bearing system is added, the core function of which is to improve overall stability and load distribution capability. In addition, to further improve the stability of this device, the other side column 6, in addition to the one where the seismic hinge 4 is installed, can be designed as two channel steels stacked together, so that the side column can resist greater lateral forces and torques, further improving the stability of this device.

[0037] like Figures 1 to 3 , Figure 5 As shown, the first support plate 15 has a second fixing hole 13, the second support plate 17 has a third fixing hole 20, and the bottom of the crossbeam 8 has a first fixing hole 11, which is an elongated oval hole. When the crossbeam 8 is connected to the first support plate 15, bolts are used to pass through the first fixing hole 11 and the second fixing hole 13; when the crossbeam 8 is connected to the second support plate 15, bolts are used to pass through the first fixing hole 11 and the third fixing hole 20. The elongated oval design of the first fixing hole 11 is to make installation more flexible.

[0038] In summary, the prefabricated support bracket provided by this utility model, through the use of corner connectors 7 and back hole connectors 9, allows the crossbeam 8 in this device to be supported. The contact between the surfaces makes the force distribution more stable, thereby making the overall support bracket more stable and reducing safety hazards. Furthermore, since the crossbeam 8 is supported, there is no need to use channel steel locking buckles, i.e., no toothed engagement is required. During installation, simply place the crossbeam 8 on the support plate and then fix it with bolts to prevent the crossbeam 8 from swaying up and down, making installation more convenient.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
