Description

Technical Field

[0001] This utility model relates to the field of building engineering equipment installation technology, and in particular to an adjustable length riser support. Background Technology

[0002] In building water supply and drainage, HVAC, and other engineering fields, the installation of risers (such as water pipes and heating pipes) requires the use of specialized brackets for fixation, while also meeting three core requirements: ease of maintenance, aesthetic appearance, and secure installation. The industry typically requires that risers be installed with a distance of approximately 5cm from the wall surface to allow sufficient operating space for future maintenance; expansion pipes, bolts, and other fasteners must not be exposed to prevent damage to the visual integrity of the wall and to ensure the strength of the fixation, preventing riser loosening and potential safety hazards.

[0003] However, existing riser supports face multiple technical challenges in actual installation: For hollow brick walls, traditional supports often use a single expansion bolt for fixing. Due to the hollow cavities inside the wall, the expansion bolt lacks solid support and is prone to "not being tightened," leading to loosening of the support and displacement of the riser. For concrete walls, which are hard and dense, traditional fasteners (such as ordinary expansion bolts) often "cannot be driven in" due to size and drilling accuracy limitations. They either cannot penetrate the wall or are difficult to lock effectively after drilling, requiring repeated replacement of parts or adjustment of drilling positions, which seriously reduces installation efficiency. At the same time, existing supports are mostly fixed structures, making it impossible to accurately adjust the distance between the riser and the wall. This can easily result in the spacing being too small (insufficient maintenance space) or too large (occupying extra space). Furthermore, the fasteners are directly exposed, affecting aesthetics and easily reducing fixing strength due to dust accumulation and corrosion.

[0004] In summary, existing pipe supports fail to design suitable fixing structures for different wall materials and lack adjustable and concealed designs. This results in difficulties in overcoming problems such as insecure fixing to hollow brick walls, difficulty in installation on concrete walls, difficulty in controlling the distance from the wall, and exposed fasteners. The industry urgently needs a new type of pipe support that can adapt to multiple wall materials, allows for precise spacing adjustment, and combines sturdiness with aesthetics to solve the above-mentioned technical pain points and meet the actual needs of engineering installation.

[0037] Example 1

[0038] Please see Figure 1 and Figure 2This utility model provides an adjustable length riser support. In the installation of risers in building water supply and drainage and HVAC engineering, the support is a core fixing component, and its performance is directly related to the stability of riser operation and the overall quality of the project.

[0039] In current engineering practice, the inadequacy of existing support systems is particularly prominent due to the significant differences in building wall materials. Hollow brick walls, being internally hollow, cannot provide effective support when fixed with traditional expansion bolts, leading to loosening or even displacement of the supports after installation. This not only affects the normal use of the risers but may also cause safety accidents. Concrete walls, with their high hardness, require repeated drilling and adjustments during the installation of traditional fasteners, often resulting in issues such as difficulty in driving in or securing the bolts, severely slowing down construction progress. Furthermore, the distance between the risers and the wall fixed by existing supports is mostly preset, unable to be flexibly adjusted according to maintenance needs. Some supports have fasteners directly exposed after installation, damaging the wall's aesthetics and potentially affecting the support's lifespan due to corrosion over time. This makes it difficult to meet the comprehensive requirements of modern building engineering for installation efficiency, safety, and aesthetics.

[0040] Please see Figure 1 In this embodiment, the adjustable riser support includes a first support rod 100 and a second support rod 200 arranged perpendicularly to each other, and a support head 110 disposed on the first support rod 100. The support head 110 has a through-hole receiving space 117 to support the placed pipe. The second support rod 200 has a fastener and a snap-fit ​​320 at one end away from the support head 110. The fastener is used to fix the support in the target position, and the snap-fit ​​320 is used to prevent the fastener from coming out of the fixed position. The support head 110 can adjust the support height based on the first support rod 100.

[0041] During the bracket installation and fixing stage, first align the fastener at the end of the second support rod 200 furthest from the support head 110 with the target position on the wall, such as the pre-set installation point on a hollow brick or concrete wall. Initially fix the bracket with the fastener. Then, utilizing the structural characteristics of the snap-fit ​​component 320, it can cooperate with the fastener to form a double fixation, effectively preventing the fastener from coming loose from its fixed position. This avoids the problems of traditional brackets being prone to loosening on hollow brick walls and difficult to fix on concrete walls, ensuring the bracket is stable and reliable after installation, laying a safe foundation for subsequent pipe support. In the pipe placement stage, the riser to be installed is placed into the through-hole receiving space 117 inside the support head 110. The receiving space 117 provides all-around enveloping support for the pipe, preventing displacement or shaking during use. Simultaneously, the first support rod 100 and the second support rod 200 are arranged perpendicularly to each other, allowing the bracket to form a stable support frame on the wall, further improving the stability of the pipe after placement, ensuring the safety of the riser during daily operation, and reducing the risk of failure caused by unstable support.

[0042] During the height adjustment phase, to facilitate maintenance of the riser by maintaining a distance of approximately 5cm from the wall, the support height is changed by adjusting the position of the support head 110 relative to the first support rod 100. The connection structure between the support head 110 and the first support rod 100 allows the support head 110 to be adjusted to a suitable height, maintaining a preset distance between the riser and the wall. After adjustment, the position of the support head 110 is stably fixed, satisfying the operational space requirements during maintenance and adapting to height requirements in different installation scenarios, thus enhancing the practicality and flexibility of the bracket.

[0043] Further, please see Figure 1 The support head 110 is connected to the first support rod 100 via a connecting rod 120; the first support rod 100 is a threaded rod, and the connecting rod 120 is sleeved on the threaded rod and can rotate based on the thread on the threaded rod to adjust the support height of the support head 110.

[0044] The first support rod 100 is also provided with a first fastening bolt 121. After the support height of the support head 110 is adjusted, the position of the support head 110 can be fixed by tightening the first fastening bolt 121 toward the end close to the connecting rod 120.

[0045] Further, please see Figure 1 and Figure 2 The support head 110 includes a first support block 111 and a second support block 114. The accommodating space 117 is disposed between the first support block 111 and the second support block 114. The first support block 111 is fixed to one end of the connecting rod 120, and the second support block 114 is detachably disposed from the first support block 111. The cross-sections of the first support block 111 and the second support block 114 are both arc-shaped, and the two ends of the first support block 111 and the second support block 114 are respectively provided with a first receiving ear 112 and a second receiving ear 113, a first fastening ear 115 and a second fastening ear 116. The first receiving ear 112, the second receiving ear 113, the first fastening ear 115 and the second fastening ear 116 are all provided with fastening holes of the same diameter. The first receiving ear 112, the second receiving ear 113, the first fastening ear 115 and the second fastening ear 116 can be used to open or close the accommodating space 117 through a detachable connector.

[0046] In the height adjustment stage, precise distance adjustment is achieved through the threaded engagement of the first support rod 100 and the connecting rod 120. Since the first support rod 100 is a threaded rod, the connecting rod 120 is fitted onto it. When the connecting rod 120 is rotated, it moves up and down along the threaded trajectory of the threaded rod, thereby driving the connected support head 110 to adjust its height synchronously. This ultimately achieves the adjustment of the distance between the riser and the wall, which can accurately adapt to a maintenance distance of about 5cm. After adjustment, the first fastening bolt 121 on the first support rod 100 is tightened towards the end near the connecting rod 120. The bolt will tightly abut against the connecting rod 120, restricting its rotation and movement along the threaded rod, thereby firmly locking the position of the support head 110. This prevents the support head 110 from shifting due to vibration during long-term use, ensuring both the accuracy of the distance adjustment and the stability of the height fixation.

[0047] In the pipe placement and fixing process, the detachable structure of the support head 110 enhances operational convenience. First, the first receiving ears 112, second receiving ears 113, first fastening ears 115, and second fastening ears 116 at both ends of the first support block 111 and the second support block 114 are loosened using detachable connectors such as bolts. Since each ear has a fastening hole with the same diameter, there is no need to repeatedly align the hole diameter during disassembly, and the receiving space 117 between the two support blocks can be quickly opened. Then, the riser is placed into the receiving space 117, and the connector is inserted into the fastening hole and tightened again to close and fix the two support blocks. Since the cross-sections of the first support block 111 and the second support block 114 are both curved, they can fit against the outer wall of the pipe after closing, forming a close-fitting support. This not only prevents the pipe from shaking in the receiving space 117 but also disperses the pressure brought by the weight of the pipe. At the same time, the detachable design also facilitates quick removal and placement during later pipe maintenance or replacement, taking into account both the stability of the installation and the convenience of maintenance.

[0048] Furthermore, the fastener includes a sleeve 310, which is fixedly disposed on the first support rod 100 at one end near the second support rod 200; a second fastening bolt 311 is also provided on the first support rod 100 between the sleeve 310 and the support head 110, and the second fastening bolt 311 is used to securely set the first support rod 100 in the fixed position; a fastening washer is also provided between the sleeve 310 and the second fastening bolt 311.

[0049] During the bracket fixing and installation phase, first align the sleeve 310 of the first support rod 100 near the second support rod 200 with the pre-set hole in the wall, such as a hole in a hollow brick or concrete wall, and insert the sleeve 310 into the hole as a transitional support structure connecting the bracket to the wall. Next, install the second fastening bolt 311 on the first support rod 100 between the sleeve 310 and the support head 110, and rotate the second fastening bolt 311 clockwise to move it closer to the wall until the second fastening bolt 311 is tightly fitted to the wall surface. The locking force of the bolt will securely fix the first support rod 100 in the target position. During the installation process, it is necessary to ensure that the fastening washer between the sleeve 310 and the second fastening bolt 311 is in a flat and fitted state to avoid affecting the fixing effect due to misalignment of the washer.

[0050] Specifically, the sleeve 310 is designed to adapt to different wall characteristics. For hollow brick walls, the sleeve 310 can fill the hollow gaps in the drilled holes, providing stable support for the second fastening bolt 311 and preventing the bolt from being unable to tighten due to direct contact with the hollow bricks. For concrete walls, the sleeve 310 reduces the difficulty of screwing the bolt directly into the hard surface, reducing the risk of bolt slippage or breakage. The second fastening bolt 311 further strengthens the connection between the first support rod 100 and the wall through threaded locking, preventing the bracket from shifting. The fastening washer increases the contact area between the second fastening bolt 311 and the sleeve 310, dispersing the pressure during bolt locking. This prevents the sleeve 310 from being damaged due to excessive local stress and improves the bolt's anti-loosening effect, ensuring the bracket remains stable during long-term use. This effectively solves the problem of traditional brackets not being securely fixed on different walls and provides reliable foundation support for subsequent riser installation.

[0051] Furthermore, the latching member 320 includes a first latching block 321 and a second latching block 322 that can rotate based on the second support rod 200; one end of the first latching block 321 and the second latching block 322 is disposed on the second support rod 200; tension springs are provided inside the first latching block 321 and the second latching block 322, and the tension springs are squeezed by the first latching block 321 and the second latching block 322 to control the opening angle of the end of the first latching block 321 and the second latching block 322 away from the second support rod 200.

[0052] Furthermore, the first latching block 321 and the second latching block 322 are arranged in an arc shape at one end near the second support rod 200, and when the tension spring is opened, the second latching block 322 is embedded in the first latching block 321 and is wrapped by the first latching block 321.

[0053] Furthermore, the first latching block 321 and the second latching block 322 have a groove-shaped cross-section, and the second latching block 322 is embedded in the first latching block 321 when the tension spring is compressed.

[0054] Furthermore, the groove cross-sectional dimensions of the first snap-fit ​​block 321 and the second snap-fit ​​block 322 are larger than the diameter of the sleeve 310.

[0055] Furthermore, in the subsequent reinforcement stage of the bracket fixing installation, the first snap-fit ​​block 321 and the second snap-fit ​​block 322 of the snap-fit ​​component 320 are aligned with the sleeve 310 that has been embedded in the wall drill hole. Since the groove cross-sectional size of the first snap-fit ​​block 321 and the second snap-fit ​​block 322 is larger than the diameter of the sleeve 310, they can be easily fitted onto the outside of the sleeve 310.

[0056] During operation, the first locking block 321 and the second locking block 322 are pressed towards the center by hand or through the pre-drilled hole at the end away from the second support rod 200. At this time, the internal tension spring is compressed and contracts, and the opening angle of the two locking blocks decreases, making it easier to enter the interior of the pre-drilled hole in the hollow brick for fixing. After the locking blocks are fully inserted into the hollow brick, the tension spring loses the external force of compression and returns to the open state, causing the first locking block 321 and the second locking block 322 to naturally open towards the end away from the second support rod 200. At the same time, because the ends of the two locking blocks near the second support rod 200 are arc-shaped, the second locking block 322 will automatically embed into the first locking block 321 and be wrapped when it opens, forming a wrapping locking of the sleeve 310. At this time, the first locking block 321 and the second locking block 322 are blocked by the hollow brick and cannot be removed from the pre-drilled hole, so as to ensure the stability of the installation.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
