Description

Technical Field

[0001] This utility model belongs to the field of support technology, specifically, it relates to a weld-free single-tube portal seismic support. Background Technology

[0002] With the increasing number of mechanical and electrical equipment used in buildings, natural disasters such as earthquakes can lead to secondary earthquake-related disasters (such as fires and gas leaks) within buildings. Therefore, engineers have begun to install seismic bracing in buildings. Seismic bracing is firmly connected to the building structure and is an important earthquake-resistant measure to effectively protect mechanical and electrical equipment and pipelines, avoid casualties or property damage within the building, and extend the time for people inside the building to safely evacuate.

[0003] Chinese patent CN210950401U discloses a seismic-resistant support, characterized by comprising a main support structure, a lateral bracing structure, a longitudinal bracing structure, and a fixing structure. The lateral and longitudinal bracing structures are respectively connected to a first pipe clamp and a second pipe clamp via seismic connectors. The lateral bracing structure provides lateral support, and the longitudinal bracing structure provides longitudinal support, thereby further ensuring that the pipe will not detach or sway. While the aforementioned prior art reduces the hazards caused by pipe swaying during vibration, the pipe position cannot be adjusted after installation, thus limiting its practical application.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a weld-free single-tube portal seismic brace, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A weld-free single-tube portal seismic brace includes: a pipe, a first pipe clamp sleeved at the center of the pipe, a housing first set on the top of the first pipe clamp, a spiral tube vertically installed at the center of the housing first, a first external threaded sleeve sleeved on the outer ring of the spiral tube, a first internal threaded rod sleeved on the inner ring of the spiral tube, a connecting seat set on the top of the first external threaded sleeve, a first rotating base set on the top of the connecting seat, and a top mounting plate set on the top of the first rotating base.

[0008] Optionally, the pipe is fitted with a second pipe clamp near both ends. An adjusting seat is provided on one side of the second pipe clamp. A bottom rotating block is rotatably mounted on the side of the adjusting seat. A second housing is provided on the top of the bottom rotating block. A second internal thread is provided through the top of the second housing. A second external thread sleeve is fitted on the surface of the second internal thread. Spring baffles are fixedly connected near both ends of the second internal thread. Springs are provided at both ends of the spring baffles. The second housing, the second internal thread, and the springs are all mirrored through the center position of the second external thread sleeve. A second rotating base is provided on the top of the upper second housing. A side mounting plate is provided on the top of the second rotating base.

[0009] Optionally, the second pipe clamp and its clamping structure are arranged in a mirror image of the center of the first pipe clamp, and the side mounting plates face opposite directions.

[0010] Optionally, a threaded base is provided on the top of the housing, and the first external threaded sleeve passes through the center of the threaded base.

[0011] Optionally, a retaining ring is provided at the top of the first external threaded sleeve and the first internal threaded rod, and the retaining ring is embedded in the connector.

[0012] Optionally, the second internal threads at both ends of the second external threaded sleeve are not connected.

[0013] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0014] 1. This weld-free single-pipe gate-type seismic brace uses a first pipe clamp to fix the pipe vertically to the ceiling, and a second pipe clamp extends to both sides and is installed on the side or ceiling for auxiliary fixation. The second internal thread on the second pipe clamp is compressed by springs on both sides through spring baffles to reduce the vibration transmitted from the side mounting plate. The vibration transmitted to the pipe is reduced, thereby further ensuring that the pipe will not fall off or shake, thus improving the seismic resistance of the entire seismic brace.

[0015] 2. This weld-free single-tube portal seismic support uses the first external threaded sleeve and the first internal threaded rod to rotate simultaneously inside and outside the pipe. In conjunction with the second external threaded sleeve located on the second pipe clamp rotating on the two second internal threaded rods, the pipe is pulled in at three points at the same time, thereby adjusting the distance between the pipe and the ceiling. This allows the pipe to still be adjusted in height after it is fixedly installed, improving the flexibility of the device.

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] Please see Figure 1-4 As shown in the figure, this embodiment provides a weld-free single-tube portal seismic support, including: pipe 1.

[0028] like Figure 1 , 2As shown, in this embodiment, a first pipe clamp 2 is sleeved at the center of the pipe 1. A housing 201 is provided on the top of the first pipe clamp 2. A threaded tube 202 is vertically installed at the center of the housing 201. A first external threaded sleeve 203 is sleeved on the outer ring of the threaded tube 202, and a first internal thread 204 is sleeved on the inner ring of the threaded tube 202. A connecting seat 207 is provided on the top of the first external threaded sleeve 203, and a first rotating base 208 is provided on the top of the connecting seat 207. A top mounting plate 209 is provided on the top of the first rotating base 208. The first pipe clamp 2 holds the pipe 1, and the top mounting plate 209 is mounted on the ceiling by fixing screws passing through the four corner mounting holes. The inner wall of the first external threaded sleeve 203 is provided with internal threads, and the first internal thread 204 is... 4. External threads are provided on the outer side. The first internal thread 204 and the first external thread sleeve 203 are both fixedly connected to the bottom of the connecting seat 207. Their centers are concentric. The inner wall and outer ring of the screw tube 202 are both threaded. On the outer side of the first internal thread 204 and the inner side of the first external thread sleeve 203, by rotating, they are engaged with the first internal thread 204 and the first external thread sleeve 203, thereby installing the top mounting plate 209 and the first pipe clamp 2. The housing 201 plays a protective role for the installation area. The top mounting plate 209 is installed on the first rotating seat 208 through the bottom extension block passing through the rotating shaft, so that the top mounting plate 209 can be rotated around the rotating shaft to adjust the orientation of the top mounting plate 209 to fit on the ceiling at different angles.

[0029] like Figure 4 As shown, in this embodiment, pipe 1 is fitted with second pipe clamps 3 near both ends. An adjusting seat 301 is provided on one side of the second pipe clamp 3. A bottom rotating block 302 is rotatably mounted on the side of the adjusting seat 301. A second housing 303 is provided on the top of the bottom rotating block 302. A second internal thread 304 is provided through the top of the second housing 303. A second external thread sleeve 307 is fitted onto the surface of the second internal thread 304. Spring baffles 305 are fixedly connected to the second internal thread 304 near both ends. Springs 306 are provided at both ends of the spring baffles 305. The second housing 303, the second internal thread 304, and the springs 306 are all mirror images of each other through the center position of the second external thread sleeve 307. A second rotating base 308 is provided on the top of the upper housing 303. A side mounting plate 309 is provided; the structure between the second rotating seat 308 and the side mounting plate 309 is similar to the structure between the first rotating seat 208 and the top mounting plate 209, both of which can ensure that the corresponding mounting plates rotate around the pivot and are fixed to the mounting surface. The end of the second inner screw 304 is supported in the housing 303 by the springs 306 at both ends of the spring baffle 305. The two springs 306 abut against the top and bottom of the inner wall of the housing 303, respectively, to stabilize the spring baffle 305 inside the housing 303. When external vibration is transmitted to the second inner screw 304, the force is dissipated by the back and forth pushing of the two springs 306, thereby reducing the shaking of the spring baffle 305, and finally reducing the force transmitted from the second pipe clamp 3 to the pipe 1, so as to achieve the vibration reduction effect.

[0030] like Figure 1 As shown, in this embodiment, the second pipe clamp 3 and its clamping structure are arranged in a mirror image of the center of the first pipe clamp 2, and the side mounting plates 309 face opposite directions. The pipe 1 is equipped with a second pipe clamp 3 near both ends. The two second pipe clamps 3 are tilted by rotating the bottom rotating block 302 in the adjusting seat 301. The side mounting plates 309 are always in contact with the mounting surface of the wall or ceiling. The two second pipe clamps 3 provide opposite support forces to the pipe 1, which, together with the vertical first pipe clamp 2, support and clamp the pipe 1, thereby stabilizing it.

[0031] like Figure 1 As shown, in this embodiment, a threaded base 205 is provided on the top of the housing 201, and the first external threaded sleeve 203 passes through the center of the threaded base 205. The threaded base 205 is fixedly installed on the housing 201. Through threaded engagement, the support between the first external threaded sleeve 203 and the housing 201 is increased. Together with the threaded sleeve 202, which is rotatably installed between the first external threaded sleeve 203 and the first internal thread 204, the housing 201 is supported. The housing 201 pulls the first pipe clamp 2 to support the pipe 1.

[0032] like Figure 2 , 3 As shown, in this embodiment, the top of the first external threaded sleeve 203 and the first internal threaded rod 204 are provided with retaining rings 206, which are embedded in the connecting seat 207. The connecting seat 207 has an annular groove, in which the retaining ring 206 is embedded. By rotating the first external threaded sleeve 203, the retaining ring 206 rotates in the connecting seat 207. The first external threaded sleeve 203 and the first internal threaded rod 204 engage with the threaded base 205 and the threaded sleeve 202, and the upper housing 201 drives the first pipe clamp 2 to move up or down to adjust the height of the pipe 1. During this process, since the retaining ring 206 rotates in the connecting seat 207, the top mounting plate 209 does not rotate with the connecting seat 207, thus achieving the adjustment of the height of the pipe 1 while the top mounting plate 209 remains fixed.

[0033] like Figure 1 As shown, in this embodiment, the second internal threads 304 at both ends of the second external threaded sleeve 307 are not connected; wherein, the second external threaded sleeve 307 on the second pipe clamp 3 connects two second internal threads 304. By rotating the second external threaded sleeve 307, the internal thread inside and the threads on the two second internal threads 304 engage simultaneously. Because the threads on the two second internal threads 304 are in opposite directions, the two second internal threads 304 are pulled in or out, thereby realizing manual adjustment of the length of the connecting mechanism of the second pipe clamp 3. This is used in conjunction with the first pipe clamp 2 to adjust the height. Since all three adjustment mechanisms must rotate simultaneously to make adjustments, vibration is also avoided from causing a single thread structure to affect the position of the pipe 1 and cause deviation.

[0034] Working principle: The pipe 1 is held by the first pipe clamp 2 and the second vertical pipe clamp 3. The top mounting plate 209 is installed on the ceiling to fix the pipe 1. The two side mounting plates 309 are installed on the side or ceiling to assist in fixation. The second internal thread 304 on the second pipe clamp 3 is squeezed by the spring baffle 305 and the springs 306 on both sides to reduce the vibration transmitted from the side mounting plate 309. The vibration transmitted to the pipe 1 is reduced, thereby further ensuring that the pipe 1 will not fall off or shake. After installation, by rotating the two second external thread sleeves 307, the coaxial second internal thread 304 is pulled further apart. At the same time, the first external thread sleeve 203 is rotated to make it mesh with the threaded base 205 and the threaded tube 202 to pull the housing 201, thereby adjusting the height of the pipe 1.
