Description

Technical Field

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

[0002] Supports and hangers are a collective term for brackets and hangers. They play a crucial role in various construction stages, bearing the weight of components and their media, constraining and limiting unreasonable displacement of building components, and controlling component vibration. They are essential for the safe operation of building facilities. Supports and hangers are mainly used in electromechanical engineering facilities such as building water supply and drainage, fire protection, heating, ventilation, air conditioning, gas, heat, electricity, and communications, where thermal displacement occurs during operation. Supports and hangers provide vertical or horizontal support, distribute loads, and ensure the stability of equipment or pipelines.

[0003] In actual installation, the supports and hangers need to be installed on the ceiling first, then the pipe sections are inserted from the side of the supports and hangers and installed on them, followed by pipe section splicing. This process involves long hours of work at height, and the support and hangers require considerable operating space to be inserted from the side. In addition, the existing support and hanger crossarms and uprights are separate before installation. The uprights need to be installed first, and then the two ends of the crossarms are simultaneously installed on the uprights to form the support and hangers. This process involves many steps and is cumbersome. Utility Model Content

[0004] The present invention aims to overcome at least one defect (deficiency) of the prior art and provide an openable support bracket that is convenient for installation.

[0005] The technical solution adopted by this utility model is to provide an openable support bracket, including a crossbar and uprights installed at both ends of the crossbar. The crossbar includes a connected horizontal plate and a side plate. One end of the crossbar is connected to the uprights via a rotating assembly, and the other end is detachably connected to the uprights. The rotating assembly includes a connecting member and a fastening assembly. The fastening assembly includes a first fastening mechanism. The connecting member includes an integrally connected upright fixing part and a crossbar fixing part. The uprights pass through the interior of the upright fixing part and are connected to the upright fixing part. The crossbar fixing part includes a front plate and a rear plate. Both the front plate and the rear plate are provided with a first through hole. The side plate is provided with a second through hole. The first fastening mechanism passes through the first through hole and the second through hole to rotatably connect the crossbar to the crossbar fixing part. There is a gap between the end of the crossbar and the upright, providing space for the crossbar to rotate around the first fastener. The first fastening mechanism is configured to slide within the first through hole, so that when the support bracket is closed, the crossbar and / or the first fastener can slide towards the upright fixing part so that the end of the crossbar abuts against the upright.

[0006] In this technical solution, the support typically has two uprights, which are respectively installed and connected to the two ends of the crossbar; the crossbar may have one or two side plates, and similarly, it may have one or two horizontal plates. For example, in this embodiment, the crossbar includes two side plates and one horizontal plate, with the two side plates respectively connected to the front and rear sides of the horizontal plate, and the horizontal plate connected to the top of the side plates.

[0007] The pole fixing part can be two sheet-like structures that clamp the pole in the middle; or it can be a hollow shell through which the pole passes and is fixedly connected, as long as it can fix the pole.

[0008] Both the front and rear panels are integrally connected to the upright fixing part. The crossbar is rotatably connected to the first fastening mechanism, allowing it to rotate relative to the crossbar fixing part. When installing ducts or other objects, the two uprights are first installed on the top of the building, with one upright already pre-installed and rotatably connected to the crossbar. After the pipe section is in place, it is hoisted into position, and then the crossbar is fixed. The operation is simple and improves installation efficiency. Furthermore, since the detachable connection end of the crossbar can be opened, it will not interfere with the installation of the pipe section. After the uprights are installed on the top of the building, the pipe section can be pre-assembled on the ground and then hoisted directly from the bottom for installation. The crossbar is then fixed to the uprights, greatly reducing the time spent working at height, making installation more convenient, and improving construction safety. Secondly, in this solution, the pipe section does not need to extend from the side of the support frame but can be hoisted directly from the bottom, significantly reducing the required operating space and making it highly adaptable. Furthermore, after the pipe section is lifted into place, since one end of the horizontal bar is already rotatably connected to the vertical bar, it is not necessary to lift both ends of the horizontal bar separately and align them with the vertical bar for installation, which reduces the installation difficulty and the technical threshold of operation.

[0009] After the upright passes through the upright fixing part, it is perpendicular to the horizontal bar. When the support is in the open state, there is a gap between the end of the horizontal bar and the upright. When the other end of the horizontal bar is connected to the upright to close the support, the horizontal bar is moved towards the upright fixing part or the first fastener is moved to move the horizontal bar, eliminating the gap and making the horizontal bar abut against the upright. Since the horizontal bar needs to bear the weight of the duct and other objects, the abutting fit between the horizontal bar and the upright can improve the firmness to a certain extent, thereby enhancing the load-bearing capacity and reducing the cost of maintenance.

[0010] Furthermore, the crossbar fixing part is also provided with a top plate, the top plate is integrally connected to the front plate and the rear plate, the top plate is provided with a third through hole, the horizontal plate is provided with a fourth through hole, and the fastening assembly also includes a second fastening mechanism;

[0011] A gap is provided between the crossbar and the top plate to provide room for the crossbar to rotate around the first fastener; when the support is closed, the second fastening mechanism passes through the third and fourth through holes to fasten the crossbar to the top plate.

[0012] Furthermore, the first fastener is configured to slide within the second through hole, so that when the support is closed, the crossbar can be moved toward the top plate to abut against the top plate.

[0013] Furthermore, the pole fixing part includes a front part, a side part, and a rear part connected in sequence. The front part is integrally connected to the front plate to form an "L" shape, the side part is integrally connected to the top plate to form an "L" shape, and the rear part is integrally connected to the rear plate to form an "L" shape. The front part, the side part, and the rear part are connected in sequence to form a cavity, and the pole passes through the cavity and is connected to the pole fixing part.

[0014] Furthermore, the upright has a fifth through hole and the side has a sixth through hole. The fastening assembly also includes a third fastening mechanism, which passes through the fifth and sixth through holes to fasten the upright to the upright fixing part.

[0015] Furthermore, the front and rear portions are right-angled trapezoids, with the long base of the front portion connected to the front plate and the long base of the rear portion connected to the rear plate.

[0016] Furthermore, both the third and sixth through holes are circular, and the size of the third through hole matches the size of the second fastener, while the size of the sixth through hole matches the size of the third fastener.

[0017] Furthermore, the first through hole is a horizontally arranged oval shape, and the second through hole is a vertically arranged oval shape.

[0018] Furthermore, the outer side of the side piece is provided with a recess that extends along the length of the crossbar.

[0019] Furthermore, one end of the crossbar is detachably connected to the upright via a fixing component. The fixing component includes an L-shaped block and several fixing mechanisms, which connect the L-shaped block to the crossbar and the upright.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] (1) When installing objects such as air ducts, two uprights are first installed on the top of the building. One of the uprights is pre-installed and has a rotating connection with the crossbar. After the pipe section is in place, it is lifted into place and then the crossbar is fixed. The operation steps are simple and the installation efficiency is improved.

[0022] (2) Since the detachable connection end of the crossbar can be opened, it will not interfere with the installation of the pipe section. After the upright is installed on the top of the building, the pipe section can be pre-assembled on the ground and then directly lifted from the bottom for installation. Then the crossbar and the upright are fixed. This greatly reduces the time spent working at height, making the installation more convenient and improving the safety of construction.

[0023] (3) In this solution, the pipe section does not need to be extended from the side of the support and hanger, but can be lifted directly from the bottom, which greatly reduces the need for operating space and has strong applicability.

[0024] (4) After the pipe section is lifted into place, since one end of the horizontal bar and the vertical bar have formed a rotatable connection, it is not necessary to lift both ends of the horizontal bar and align them with the vertical bar at the same time, which reduces the installation difficulty and the technical threshold of operation.

Detailed Implementation

[0034] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0035] Example 1

[0036] refer to Figure 1 and Figure 2 as well as Figures 4 to 8 This embodiment provides an openable support bracket, including a crossbar 200 and uprights 100 installed at both ends of the crossbar 200. The crossbar 200 includes a horizontal plate 210 and a side plate 220 connected together. One end of the crossbar 200 is connected to the upright 100 via a rotating assembly, and the other end is detachably connected to the upright 100. The rotating assembly includes a connector 300 and a fastening assembly. The fastening assembly includes a first fastening mechanism 410. The connector 300 includes an integrally connected upright fixing part 310 and a crossbar fixing part 320. The upright 100 passes through the interior of the upright fixing part 310 and is connected to the upright fixing part 310. The crossbar fixing part 320 includes a front plate 321. Both the front plate 321 and the rear plate 322 are provided with a first through hole 3211, and the side plate 220 is provided with a second through hole 221. The first fastening mechanism 410 passes through the first through hole 3211 and the second through hole 221 to rotatably connect the crossbar 200 to the crossbar fixing part 320. There is a gap between the end of the crossbar 200 and the upright 100 to provide room for the crossbar 200 to rotate around the first fastener. The first fastening mechanism 410 is configured to slide in the first through hole 3211 so that when the support is closed, the crossbar 200 and / or the first fastener can slide towards the upright fixing part 310 so that the end of the crossbar 200 abuts against the upright 100.

[0037] The support typically has two uprights 100, which are respectively installed and connected to both ends of the crossbar 200. The crossbar 200 may have one side plate 220 or two side plates 220. Similarly, it may have one horizontal plate 210 or two horizontal plates 210. For example, in this embodiment, the crossbar 200 includes two side plates 220 and one horizontal plate 210. The two side plates 220 are respectively connected to the front and rear sides of the horizontal plate 210, and the horizontal plate 210 is connected to the top of the side plates 220.

[0038] The pole fixing part 310 can be two sheet-like structures that clamp the pole 100 in the middle; or it can be a hollow shell through which the pole 100 passes and is fixedly connected, as long as it can fix the pole 100.

[0039] Both the front plate 321 and the rear plate 322 are integrally connected to the upright fixing part 310. The crossbar 200 is rotatably connected to the first fastening mechanism 410, allowing the crossbar 200 to rotate relative to the crossbar fixing part 320. When installing objects such as ducts, the two uprights 100 are first installed on the top of the building, with one upright 100 already pre-installed and rotatably connected to the crossbar 200. After the pipe section is in place, it is lifted into position, and then the crossbar is fixed. The operation steps are simple, improving installation efficiency. In addition, since the detachable connection end of the crossbar can be opened, it will not interfere with the installation of the pipe section. After the upright 100 is installed on the top of the building, the pipe section can be pre-assembled on the ground and then directly lifted from the bottom for installation. Then the crossbar 200 is fixed to the upright 100, which greatly reduces the time spent working at height, making installation more convenient and improving construction safety. Secondly, in this design, the pipe section does not need to extend from the side of the support; instead, it can be lifted directly from the bottom, greatly reducing the required operating space and making it highly adaptable. Furthermore, after the pipe section is lifted into place, since one end of the horizontal bar 200 is already rotatably connected to the vertical bar 100, it is not necessary to simultaneously lift both ends of the horizontal bar 200 and align them with the vertical bar 100, thus reducing installation difficulty and lowering the technical barrier to operation.

[0040] After the upright 100 passes through the upright fixing part 310, it is perpendicular to the horizontal bar 200. When the support is in the open state, there is a gap between the end of the horizontal bar 200 and the upright 100. When the other end of the horizontal bar 200 is connected to the upright 100 to close the support, the horizontal bar 200 is moved towards the upright fixing part 310 or the first fastener is moved to move the horizontal bar 200, eliminating the gap and making the horizontal bar 200 abut against the upright 100. Since the horizontal bar 200 needs to bear the weight of objects such as air ducts, the abutting and fitting of the horizontal bar 200 and the upright 100 can improve the firmness to a certain extent, thereby enhancing the load-bearing capacity and reducing the cost of maintenance.

[0041] For example, the first fastening mechanism 410 can be a bolt structure. After the bolt passes through the first through hole 3211 and the second through hole 221, the nut is tightened to achieve fixation. The first through hole 3211 can be any structure that allows the first fastener to slide inside it, such as rectangular, elliptical, or oval. The outer side of the side plate 220 is provided with a recess 222, which extends along the length of the crossbar 200, saving material and reducing the overall weight while ensuring a firm connection.

[0042] Furthermore, the crossbar fixing part 320 is also provided with a top plate 323, which is integrally connected to the front plate 321 and the rear plate 322. The top plate 323 is provided with a third through hole 3231, and the horizontal plate 210 is provided with a fourth through hole 211. The fastening assembly also includes a second fastening mechanism 420. A gap is provided between the crossbar 200 and the top plate 323 to provide room for the crossbar 200 to rotate around the first fastener. When the support is closed, the second fastening mechanism 420 passes through the third through hole 3231 and the fourth through hole 211 to fasten the crossbar 200 to the top plate 323.

[0043] The top plate 323 can be integrally connected to the upright fixing part 310, or it can be connected only to the front plate 321 and the rear plate 322. After the top plate 323, the front plate 321 and the rear plate 322 are connected, the cross-section of the structure formed is an inverted "U". When the detachable end of the crossbar 200 is separated from the upright 100 to open the support bracket, there is a gap between the end of the crossbar 200 and the top plate 323 to provide room for the crossbar 200 to rotate. When the other end of the crossbar 200 is connected to the upright 100 to close the support bracket, the crossbar 200 is moved towards the upright fixing part 310 to eliminate the gap between it and the upright 100. Then, the second fastening mechanism 420 further fixes the crossbar 200 to the crossbar fixing part 320, which greatly improves the stability of the support bracket.

[0044] For example, the second fastening mechanism 420 can be a bolt structure. After the bolt passes through the third through hole 3231 and the fourth through hole 211, the nut is tightened to achieve fixation.

[0045] Furthermore, the first fastener is configured to slide within the second through hole 221, so that when the support is closed, the crossbar 200 can be moved toward the top plate 323 to abut against the top plate 323.

[0046] The second through hole 221 can be any structure that allows the first fastener to slide inside, such as rectangular, elliptical, or oval. When the support bracket is closed, the crossbar 200 is moved towards the upright fixing part 310 to eliminate the gap between it and the upright 100, and then moved towards the top plate 323 to eliminate the gap between it and the top plate 323. The crossbar 200 is then fastened with the second fastener. This allows the crossbar 200 to abut against and fit against the top plate 323 after the support bracket is closed. While enabling relative movement between the crossbar 200 and the upright 100, the support bracket also has excellent stability and load-bearing capacity, and is simple to operate, saving operation time.

[0047] Preferably, the first through hole 3211 is a horizontally arranged oval shape, and the second through hole 221 is a vertically arranged oval shape. Compared to a square shape, the oval through hole has no corners, avoiding dust accumulation at the corners.

[0048] Furthermore, the upright fixing part 310 includes a front part 311, a side part 313, and a rear part 312 connected in sequence. The front part 311 is integrally connected to the front plate 321 to form an "L" shape, the side part 313 is integrally connected to the top plate 323 to form an "L" shape, and the rear part 312 is integrally connected to the rear plate 322 to form an "L" shape. The front part 311, the side part 313, and the rear part 312 are connected in sequence to form a cavity, and the upright 100 passes through the cavity and is connected to the upright fixing part 310.

[0049] The upright fixing part 310 and the horizontal bar fixing part 320 are connected to form an L-shaped connection structure. The vertical part is connected to the upright 100, and the horizontal part is connected to the horizontal bar 200. The upright 100 and the horizontal bar 200 are perpendicular to each other. The upright 100 can be connected to the upright fixing part 310 by a fixed connection or a detachable connection, as long as the connection and fixation of the two can be achieved.

[0050] For example, the upright 100 is provided with a fifth through hole 110, and the side portion 313 is provided with a sixth through hole 3131. The fastening assembly also includes a third fastening mechanism 430, which passes through the fifth through hole 110 and the sixth through hole 3131 to fasten the upright 100 to the upright fixing portion 310. This forms a detachable connection that is stable and easy to assemble and disassemble. Specifically, both the third through hole 3231 and the sixth through hole 3131 are circular, and the size of the third through hole 3231 matches the second fastener, while the size of the sixth through hole 3131 matches the third fastener.

[0051] The third fastening mechanism 430 can be a bolt structure. After the bolt passes through the fifth through hole 110 and the sixth through hole 3131, the nut is tightened to achieve fixation. Bolts, screws, and other fasteners typically have a circular cross-section. The size of the third through hole 3231 and the sixth through hole 3131 matches the cross-sectional size of the fastener, and their circular shape allows the through holes to more effectively limit the bolt and improve the connection's firmness. Specifically, the fourth through hole 211 and the fifth through hole 110 can be oval, which has a larger area than a circle, facilitating fastener alignment and connection, and improving the efficiency of installation work. More specifically, the upright 100 is provided with multiple fifth through holes 110. During installation, the through hole can be selected according to actual needs to adjust the height of the crossbar 200 and improve the applicability of the support.

[0052] Furthermore, the front part 311 and the rear part 312 are right-angled trapezoids, with the long base of the front part 311 connected to the front plate 321 and the long base of the rear part 312 connected to the rear plate 322.

[0053] In this design, since the crossbar fixing part 320 connects to the crossbar 200 to form the main load-bearing structure, the connection between the long base of the right trapezoid and the crossbar fixing part 320 can further increase the load-bearing capacity and ensure the connection is firm. Preferably, the sloping waists of the front part 311 and the rear part 312 are located at the bottom, and the right-angled waist is located at the top. The connector 300 has a chamfered structure. Compared to the front part 311 and the rear part 312 being square, this design saves materials, reduces costs, and also reduces the weight of the connector 300.

[0054] refer to Figure 1 and Figure 3 Furthermore, one end of the crossbar 200 is detachably connected to the upright 100 via a fixing component. The fixing component includes an L-shaped block 500 and several fixing mechanisms 600, which connect the L-shaped block 500 to the crossbar 200 and the upright 100. The end of the crossbar 200 abuts against the upright, and its top surface abuts against the L-shaped block 500, thus improving the overall stability of the support. Preferably, there are two fixing mechanisms 600, which can be bolt structures, including bolts and nuts. One bolt passes through the L-shaped block 500 and the crossbar 200 and is fixed with the nut, while the other bolt passes through the L-shaped block 500 and the upright 100 and is fixed with the nut.

[0055] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the technical solution of this utility model, and are not intended to limit the specific implementation of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the claims of this utility model should be included within the protection scope of the claims of this utility model.
