Description

Technical Field

[0001] The present application relates to the field of building construction, and specifically to a middle support hanger for building electromechanical installation using a single-row hole vertical pole. Background Art

[0002] Currently, there are two commonly used prefabricated bracket systems. One uses mechanical meshing between the teeth of the channel steel and the teeth of the lock, relying on mechanical friction to form a connection between the profiles. The disadvantage of this method is that it places high demands on the product and installers, and it is prone to teeth slippage, posing a safety hazard. The other type of prefabricated bracket is bolted, utilizing the openings in the channel steel and connecting with bolts. This connection method is safer, completely avoiding the risk of teeth slippage, and is less demanding on the installer. This type of connection is currently tending to gradually replace the first type of prefabricated bracket.

[0003] For the finished bolted bracket, there is no good connector for the use of multiple poles. There are two conventional practices. One is to use a single row of holes in the pole channel steel. The solution to the connection between the middle pole and the cross arm in multiple poles is to use double-spliced ​​poles after aligning the holes. This method causes the poles to be selected too large, resulting in unnecessary waste; at the same time, the installation is not convenient enough.

[0004] Another form adopted is to use connectors for the vertical poles, which are oblique connectors. The two ends of the oblique connectors are respectively connected to the vertical poles and the horizontal poles. The holes in the vertical poles are double rows of holes, and the holes in the double rows of holes are used to connect to the cross arms through connectors. The disadvantage of this form is that the purpose of using double rows of holes for the vertical poles is to solve the connection problem of the cross arms on the opposite sides of multiple vertical poles. The problem can be solved by using certain connectors, but the strength of the vertical poles is greatly reduced after using double rows of holes. At the same time, the installation of the connectors is not convenient enough, and the connectors take up a large space, which is not suitable for the overall concept of controlling pipeline elevations in most current projects.

[0005] Therefore, by designing a connector that is easy to install, has free space management, and can save materials while achieving the safety force value, it becomes the first choice for the application of multi-pole finished brackets. Utility Model Content

[0006] The purpose of the utility model is to provide a single-row hole vertical pole building mechanical and electrical installation center support hanger to solve the problems mentioned in the background technology.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A single-row hole vertical pole building mechanical and electrical installation middle support hanger, including a cross arm channel steel and a vertical pole channel steel, the vertical pole channel steel is a single-row hole vertical pole, and the cross arm channel steel is a double-piece channel steel cross bar; it is characterized in that: the bottom surface of the vertical pole channel steel is flush with the bottom plate of the cross arm channel steel, and are connected by a Z-shaped connecting piece; the Z-shaped connecting piece includes a first horizontal plate, a vertical plate and a second horizontal plate connected in sequence, the first horizontal plate is provided with four connecting holes, which respectively correspond to the four connecting holes of the double-piece channel steel cross bar, and the second horizontal plate is provided with two connecting holes, which respectively correspond to the two vertical connecting holes of the single-row hole vertical pole.

[0009] Further preferably, the length of the second transverse plate is equal to the width of the side wing.

[0010] Furthermore, the width of the vertical plate is equal to the thickness of the side wing of the vertical column channel steel, or is greater than the thickness of the side wing of the vertical column channel steel.

[0011] Furthermore, the upper part of the vertical pole channel steel is connected to the top surface of the structure through a connecting piece, and the connecting piece includes a connecting body with a U-shaped cross-section and ear plates located on both sides of the connecting body. The opening of the connecting body faces the web of the vertical pole channel steel, and the bottom plate of the connecting body is overlapped with the web and connected to the vertical pole channel steel by bolts, and the ear plates are connected to the top surface of the structure by expansion bolts.

[0012] Furthermore, the double-piece channel steel cross bar is passed between the two side wing plates at the lower part of the vertical pole channel steel.

[0013] In addition, the diameter of the connection hole is set as needed, preferably less than 1 cm.

[0014] More preferably, the Z-shaped connector is formed by precise stamping and bending of aluminum alloy material.

[0015] Compared with the prior art, the present invention has the following characteristics and beneficial effects:

[0016] This application uses a single-row hole vertical pole with this Z-shaped connector to solve the problem that one side of the vertical pole channel steel is connected to the cross arm with through bolts, and the other side is connected to the vertical pole through this connector. After using this connector, the vertical pole does not need to be double-spliced, and the lower end of the vertical pole does not need to be specially reserved. Therefore, it can simultaneously solve the pipeline space management problem and save bracket space.

[0017] The design of the vertical poles in this application still uses a single row of holes. The cross arms on both sides can be connected to the holes that fit the vertical poles through the Z-shaped connectors through the same set of bolts. The strength of the vertical poles is greatly improved compared to the double-row hole vertical poles, and the selection of the vertical poles is more economical than the double-row hole vertical poles. Therefore, this type of connector can not only save materials, but also improve construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] A single-row hole vertical pole building mechanical and electrical installation middle support hanger, such as Figures 1-3 As shown, it includes a cross arm channel steel 1 and a vertical pole channel steel 2, the vertical pole channel steel 2 is a single-row hole vertical pole, and the cross arm channel steel 1 is a double-piece channel steel cross bar; the bottom surface of the vertical pole channel steel 2 is flush with the bottom plate of the cross arm channel steel 1, and is connected by a Z-shaped connector 3; the Z-shaped connector 3 includes a first horizontal plate 31, a vertical plate 32 and a second horizontal plate 33 connected in sequence, the first horizontal plate 31 is provided with four connecting holes, which correspond to the four connecting holes of the double-piece channel steel cross bar respectively, the second horizontal plate 33 is provided with two connecting holes, which correspond to the two vertical connecting holes of the single-row hole vertical pole respectively, the length of the second horizontal plate 33 is the same as the width of the side wing, and the width of the vertical plate 32 is the same as the thickness of the side wing of the vertical pole channel steel 2 Equal to, or greater than the thickness of the side flanks of the upright channel steel 2, the upper part of the upright channel steel 2 is connected to the top surface of the structure through a connector 4, the connector 4 includes a connecting body 41 with a U-shaped cross-section and ear plates 42 located on both sides of the connecting body 41, the opening of the connecting body 41 faces the web of the upright channel steel 2, and the bottom plate and the web of the connecting body 41 are overlapped and connected to the upright channel steel 2 by bolts, the ear plates 42 are connected to the top surface of the structure by expansion bolts, the double-piece channel steel cross bar is passed between the flanks on both sides of the lower part of the upright channel steel 2, the diameter of the connecting hole is set as needed, and the Z-shaped connector 3 is precisely stamped and bent by aluminum alloy material.

[0024] The design concept of the Z-shaped connector in this application is as follows: adopting a horizontal design and precise stamping and bending to achieve a horizontal stepped transition of the connector, ensuring that the two-hole end holes of the connector correspond to the two hole positions of the vertical column channel steel, and the four-hole end holes correspond to the four hole positions of the crossarm channel steel. During installation, the connector naturally corresponds to the six hole positions of the channel steel. After fastening with through bolts, the crossarm and the vertical column channel steel fit seamlessly, horizontally and vertically, firmly integrated, and without the risk of shaking or displacement. At the same time, the structural characteristics of the connector itself act like a spacer, increasing the strength of the bolt penetration areas of the column and crossarm channel steel, improving overall stability.

[0025] This new design overcomes the shortcomings of existing connectors, such as space occupation or wasteful material selection for poles. While ensuring strength, it also addresses the challenges of saving materials, increasing overall pipeline elevation, and improving work efficiency. The Z-shaped connector is integrally molded and stamped, utilizing advanced production technology, resulting in improved product precision and a novel appearance that complements the overall decor. It is particularly effective in areas where pipeline elevations are strictly controlled, offering superior overall performance and wide application potential for support and hanger installation, truly meeting the needs of the industry's newest system installation process.
