[0002] In recent years, with the vigorous development of steel structure buildings in my country, more and more supports and hangers have been used in steel structure buildings.

[0003] In steel structure buildings, rigid supports and hangers are usually used to install and fix various pipelines used in electromechanical operations. That is, the supports and hangers are fixed to the I-beams by bolting or welding. However, this installation method is not only expensive, but also causes certain structural damage to the I-beams, which has an adverse effect on the structural performance of the I-beams.

[0004] In order not to destroy the structural performance of the original I-beam, people have invented flexible support and hanger nodes. However, the current flexible support and hanger nodes have the problem of complex structure and troublesome assembly and disassembly.

[0015] In a second aspect, the present application provides a method for installing a flexible support and hanger node of an I-beam.

[0016] A method for installing an I-beam flexible support and hanger node comprises the following steps:

[0017] S1: Fit the second clamping plate to the lower end surface of the I-beam flange;

[0018] S2: Pass the clamping rod through the long hole;

[0019] S3: Pass the pressing rod through the rod hole, and extend the rod into the clamping groove. At this time, the screw rod passes through the outside of the rod hole;

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. Connecting the clamping part to the lower end of the I-beam will not damage the I-beam structure. If an earthquake or other vibration occurs, and the pipe rack and the pipes on it shake horizontally, the steel cable will support the pipe rack, reducing the horizontal force on the pipe rack and the pipes on it, thereby protecting the I-beam and pipelines.

The structure is simple and the connection is convenient.

[0025] 3. During installation, first pass the clamping rod through the long hole and let the end abut against the side wall of the support plate 1. Then place the clamping rod above the steel beam at the lower end of the I-beam. Then use the clamping piece to clamp the clamping rod and the support plate 2, and then clamp the I-beam. The structure is simple and clamping is convenient.

[0026] 4. First, place the angle steel in contact with the lower end of the I-beam, pass the clamping rod through the long hole, and then place the clamping rod on the upper end surface of the steel beam at the lower end of the I-beam. Fit the second support plate with the lower end surface of the I-beam flange, then pass the clamping rod through the rod hole from top to bottom, place the extension rod inside the clamping groove, and then put the nut on the screw located on the outside of the second support plate. By turning the nut, the extension rod drives the clamping rod to clamp, and then the clamping rod and the second support plate are used to clamp the I-beam. The structure is simple, clamping is convenient, fewer parts are required, and the cost is low.

[0027] 5. When installing the clamping rod, insert the positioning rod into the positioning groove. At this time, the extension rod enters the clamping groove. At this time, the screw rod can directly pass through the rod hole, thereby improving the convenience of inserting the screw rod and the convenience of subsequent clamping of the I-beam;

[0028] 6. During disassembly, after removing the nut from the screw, you can grab the two grab ears, then pull the extension rod out of the clamping groove, and then pull the screw out of the rod hole, thereby improving the convenience of disassembling the clamping part.

DETAILED DESCRIPTION

[0041] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0042] In a first aspect, an embodiment of the present application discloses a flexible support and hanger node for an I-beam.

[0043] Example 1:

[0044] Reference Figure 1 and Figure 2 A flexible support and hanger node for an I-beam comprises a clamping portion 1 which is detachably connected to the flange of an I-beam 100.

If an earthquake or other vibration occurs, and the pipe rack and the pipes on the pipe rack shake horizontally, the steel cable 7 supports the pipe rack, which can reduce the horizontal force on the pipe rack and the pipes on the pipe rack, thereby protecting the pipe rack and the pipes on the pipe rack.

[0046] The other end of the steel cable 7 may also be connected to only one pipe, and one end of the steel cable 7 may be wound around the outside of the pipe.

[0047] Reference Figure 3 and Figure 4 A long hole 21 is provided on the support plate 2, the diameter of the long hole 21 is 20 mm, and the length of the long hole 21 is 30 mm; when installing the clamping part 1, the support plate 2 3 is fitted to the lower end surface of the flange of the I-beam 100, and then the clamping rod 4 is passed through the long hole 21, so that the clamping rod 4 and the support plate 2 3 are parallel to each other, and the clamping rod 4 is placed on the upper end surface of the steel beam at the lower end of the I-beam 100; an end head 41 is provided at one end in the length direction of the clamping rod 4, the diameter of the end head 41 is 30 mm, the diameter of the end head 41 is larger than the width of the long hole 21, and the end head 41 abuts against the side wall of the support plate 2.

[0048] Reference Figure 5 and Figure 6 The clamping part includes a clamping rod 5, the clamping rod 5 has a diameter of 18 mm and a length of 40 mm. The upper end of the clamping rod 5 is fixedly connected to an extension rod 51, and the extension rod 51 and the clamping rod 5 are arranged perpendicular to each other. A clamping groove 42 is provided on the clamping rod 4, and the clamping groove 42 has a groove depth of 5 mm. The width of the clamping groove 42 is greater than the width of the extension rod 51. A clamping bolt 52 is provided at the lower end of the clamping rod 5, and the clamping bolt 52 includes a screw 53 and a nut 54.

[0049] Reference Figure 3 and Figure 5, the support plate 2 3 is provided with a rod hole 31, and the diameter of the rod hole 31 is 20 mm; the extension rod 51 is placed inside the clamping groove 42, and the screw 53 passes through the outside of the rod hole 31, and then the nut 54 can be sleeved on the outside of the screw 53, and the nut 54 is rotated. As the nut 54 rotates, the nut 54 moves toward the direction of the support plate 2 3, and the nut 54 continues to be rotated. Under the action of the extension rod 51 and the clamping rod 5, the clamping rod 4 and the support plate 2 3 are clamped in the direction of approaching each other, and then the I-beam 100 is clamped. The structure is simple, the clamping is convenient, the required parts are few, the cost is low, and the construction speed is fast.

[0050] Reference Figure 3 and Figure 5 During disassembly, by rotating the nut 54, the nut 54 moves away from the screw rod 53. At this time, the clamping force of the clamping rod 4 and the support plate 23 on the I-beam 100 disappears, and the angle steel and the clamping rod 4 can be easily removed, making disassembly more convenient.

[0051] The working principle of the flexible support and hanger node of the I-beam in the embodiment of the present application is as follows: during installation, first fit the support plate 2 3 to the lower end of the I-beam 100, then pass the clamping rod 4 through the long hole 21, and then place the clamping rod 4 on the upper end surface of the steel beam at the lower end of the I-beam 100, then pass the pressing rod 5 through the rod hole 31 from top to bottom, place the extension rod 51 inside the clamping groove 42, and then put the nut 54 on the screw 53 located on the outside of the support plate 2 3, and by rotating the nut 54, the extension rod 51 drives the clamping rod 4 to clamp, and then use the clamping rod 4 and the support plate 2 3 to clamp the I-beam 100. The clamping is simple in structure, convenient in clamping, requires fewer parts, and has lower cost. During disassembly, by rotating the nut 54, the nut 54 is moved away from the screw rod 53. At this time, the clamping force of the clamping rod 4 and the support plate 2 3 on the I-beam 100 disappears, and the angle steel and the clamping rod 4 can be easily removed, making disassembly more convenient. If an earthquake or other vibration occurs, when the pipe rack and the pipes on the pipe rack shake horizontally, the steel cable 7 supports the pipe rack, which can reduce the horizontal force on the pipe rack and the pipes on the pipe rack, thereby protecting the pipe rack and the pipes on the pipe rack.

[0052] Example 2:

[0053] Reference Figure 7 and Figure 8 The difference between the second embodiment and the first embodiment lies in the different arrangements of the extension rod 51 and the clamping rod 4 .

[0054] Reference Figure 8 and Figure 9The lower end of the extension rod 51 is provided with a positioning rod 8 which is arranged perpendicularly to the extension rod 51, and the clamping rod 4 is provided with a positioning groove 81 which is communicated with the clamping groove 42 and is matched with the positioning rod 8.

[0055] With reference to Figure 7 and Figure 8 , since the screw rod 53 needs to be inserted into the rod passing hole 31 from top to bottom, and the screw rod 53 is far away from the rod passing hole 31, the insertion is difficult, therefore, when the insertion is performed, the positioning rod 8 can be firstly inserted into the positioning groove 81 (with reference to Figure 9 ), at this time, the extension rod 51 enters into the clamping groove 42, at this time, the screw rod 53 can be directly passed through the rod passing hole 31, thereby improving the convenience of inserting the screw rod 53, and thereby improving the convenience of clamping the I-shaped steel 100 subsequently.

[0056] Embodiment three:

[0057] With reference to Figure 10 and Figure 11 , the difference between the embodiment three and the above-mentioned embodiments lies in the different arrangement of the extension rod 51.

[0058] With reference to Figure 10 and Figure 11 , the extension rod 51 is provided with a grabbing ear 9 on both sides in the length direction, when the clamping part 1 is disassembled, after the nut 54 is disassembled from the screw rod 53, the extension rod 51 can be pulled out from the clamping groove 42 by grabbing the two grabbing ears 9, and then the screw rod 53 is pulled out from the rod passing hole 31, thereby improving the convenience of disassembling the clamping part 1.

[0059] In a second aspect, the embodiment of the present application discloses a mounting method of an I-shaped steel beam flexible support hanger joint.

[0060] The mounting method of the I-shaped steel beam flexible support hanger joint comprises the following steps:
