Description

Technical Field

[0001] This invention relates to the field of mounting bracket technology, and in particular to a two-section adjustable bracket and construction method for roof tile systems. Background Technology

[0002] In traditional roof tile systems, the support structure is usually a fixed design, which is difficult to adapt to different roof angles, crossbar heights, and cable layouts. Existing supports mostly rely on welding or bolts for direct fixation, resulting in poor adjustability, low installation efficiency, and limited adaptability. For example, when the height of the roof crossbars needs to be adjusted due to construction errors or design changes, traditional supports need to be disassembled and reassembled, or even have parts replaced, increasing costs and construction time. In addition, additional cable fixing devices need to be installed for roof wiring, resulting in structural redundancy. To address these issues, we propose a two-section adjustable support and construction method for roof tile systems. Summary of the Invention

[0008] As a preferred embodiment of the present invention, two third sliding grooves are provided on the inner side of the second adjusting bracket, and a second slider is fixedly installed on the outer side of the fixing bracket corresponding to the position of the third sliding groove. The second slider is slidably installed inside the third sliding groove, and a second locking block is fixedly installed at equal intervals on the inner side of the third sliding groove.

[0009] As a preferred embodiment of the present invention, a slot is provided between the two fixed frames.

[0011] A construction method for a two-section adjustable bracket applied to a roof tile hanging system includes the following steps: Step 1: According to the roof design drawings and crossbar installation requirements, check and mark the installation baseline of each fixed bracket and the preset height of the crossbar; Step 2: Select the corresponding installation program based on the detection results of Step 1; Step 2.1: If a single horizontal bar is to be installed, the corresponding fixed brackets should be installed independently according to the baseline, and the height of each bracket should be adjusted to the preset value. Step 2.2: If multiple crossbars are installed continuously, install multiple fixed brackets sequentially along the baseline and adjust them to the same height reference using the first slider. Step 3: Install and adjust the horizontal bar. Adjust the horizontal and pitch angles using the first and third rotating columns respectively, so that the second adjusting bracket is aligned with and supports the horizontal bar. Step 4: Perform cable laying and fixing operations. Place the cable on the support plate, and use the fixing bracket to press down and use the squeezing block to clamp and fix the cable. Step 5: After the crossbar and cable are installed, the locking status of the fixing frame and the clamping stability of the cable are tested using a testing device. Step 5.1: If the mounting bracket is locked in place and the cables are not loose, the installation is considered successful, and proceed to step 6. Step 5.2: If the mounting bracket is not properly locked or the cable is loose, adjust the locking position of the mounting bracket or readjust the downward pressure of the mounting bracket until the locking state meets the requirements, then return to step 5 for re-inspection. Step 6: Conduct a final inspection and adjustment of the installed bracket to confirm that the fixed bracket is not loose, all adjustment parts are securely locked, the crossbar is installed smoothly, and the cables are firmly fixed.

[0012] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. This invention achieves stepless adjustment and stable locking of the bracket height by using a first slider and a first threaded post inside the fixed bracket. The first sliding groove on the side wall of the fixed bracket and the constraint groove on the side of the first slider are slidably connected by a constraint block to ensure that the first slider moves smoothly only in the vertical direction and avoids deflection. When the rotating disk drives the first threaded post to screw into the first threaded hole, the compression pad between its end and the wall of the fixed bracket is deformed by pressure, forming a friction self-locking to prevent the thread from loosening. This structure allows the bracket to adapt to the height requirements of different roof crossbars, and adjustment and fixing can be completed with a single operation, significantly improving installation accuracy and efficiency.

[0013] 2. This invention achieves flexible adjustment and rigid fixation of the horizontal angle through the rotating connection structure between the connecting column and the first rotating column. The first rotating block is embedded in the first rotating cavity, allowing the first rotating column to rotate freely around the axis of the connecting column, adapting to changes in the horizontal layout of the crossbar. After the second rotating column passes through the guide hole, the second threaded column at its end engages with the threaded groove. When the rotating handle presses against the end face of the first rotating column, it generates an axial preload, eliminating rotational clearance. This design ensures both the flexibility of angle adjustment and provides a high-strength connection through threaded locking, preventing the bracket from shifting due to wind vibration or load.

[0014] 3. This invention achieves multi-directional self-adaptation in three-dimensional space by using the rotational connection design between the clamping block and the third rotating column, combined with the lateral angle adjustment mechanism of the first adjusting bracket. The rotational pair between the fourth rotating column and the rotating hole allows the third rotating column to tilt relative to the clamping block, adjusting the longitudinal tilt angle of the first adjusting bracket. At the same time, the second rotating block slides in the rotating groove and is tightened and fixed by the third threaded column screwed into the second threaded hole, achieving lateral angle adjustment. The combination of the two allows the bracket to adapt to the combined deviation of the roof slope and the spatial orientation of the crossbar, reducing on-site cutting or customization costs.

[0015] 4. This invention achieves the dual functions of fixing the crossbar and clamping the cable simultaneously through the linkage design of the fixing frame and the extrusion structure. The slot on the side of the fixing frame is inserted into the first locking block, and the first spring provides elastic pre-pressure, so that the extrusion plate adapts to crossbars of different diameters, avoiding metal-to-metal contact that could damage the surface. When the fixing frame moves down, the bottom of the extrusion block presses the extrusion block, which drives the sliding block to stretch the second spring, generating pressure on the cable above the support plate. This structure solves the problems of crossbar stability and cable laying in a single action, simplifying the construction process.

[0016] 5. This invention improves the load-bearing safety and adjustment repeatability of the bracket through the snap-fit ​​limiting structure of the second slider and the third slide groove. When the second slider moves down along the third slide groove, the limiting block on its side and the second snap-fit ​​block distributed at equal intervals form a stepped engagement, preventing the fixing bracket from accidentally slipping off under vibration or load. This design not only ensures the position is controllable during the adjustment process, but also disperses stress through multi-point snap-fit ​​to avoid single-point fatigue failure. In conjunction with the spring reset mechanism of the squeezing block, it ensures that the cable fixing pressure is constant and extends the service life of the system. Attached Figure Description

The angle of the first adjusting bracket 311 is adjusted to accommodate crossbars with different tilt angles. The first slider 211 is moved upward to adjust the height of the first adjusting bracket 311 and the second adjusting bracket 312, so that the second adjusting bracket 312 tightens the crossbar. The first threaded column 222 is rotated inside the first threaded hole 221.

When wiring is required, the cable is passed through the top of the support plate 352. When the fixing frame 353 moves downward, the fixing frame 353 presses the pressing block 374 downward. The pressing block 374 presses and fixes the cable. The position of the first locking block 355 on the fixing frame 353 is adjusted according to the height of the support crossbar. When the fixing frame 353 moves downward, the pressing plate 357 and the first spring 356 press the top of the crossbar to assist in fixing the crossbar. When the fixing frame 353 moves downward, it presses the pressing block 374. The pressing block 374 and the support plate 352 press the cable set above the support plate 352.

[0022] like Figure 1 and Figure 3As shown, specifically, a first sliding groove 112 is provided on the upper side of the fixed bracket 111. The first sliding groove 112 is a rectangular groove. A first recess 113 penetrating the wall of the fixed bracket 111 is provided on the side of the fixed bracket 111 corresponding to the center position of the first sliding groove 112. Two constraint grooves 212 are provided on the side of the first slider 211. A constraint block 213 is fixedly installed inside the first sliding groove 112 corresponding to the position of the constraint groove 212. The constraint block 213 is slidably disposed inside the constraint groove 212. A compression pad 224 is provided on the outer side of the first threaded post 222 between the rotating disk 223 and the wall of the fixed bracket 111. A first rotating cavity 233 is provided at one end of the connecting post 231 corresponding to the first rotating post 232. A first rotating block 234 is fixedly installed at the position of the first rotating post 232 corresponding to the position of the first rotating cavity 233. The first rotating block 234 is rotatably installed inside the first rotating cavity 233. A threaded groove 236 is provided inside the connecting post 231. A penetrating groove 236 is provided inside the first rotating post 232. The guide hole 235 of the column 232 and the first rotating block 234 has a second rotating column 237 rotatably mounted inside the guide hole 235. A second threaded column 238 is fixedly mounted on the end face of the second rotating column 237. The second threaded column 238 is threaded into the inside of the threaded groove 236. A rotating handle 239 is fixedly mounted on one end of the second rotating column 237. A third rotating column 323 is rotatably mounted on the side of the clamping block 324. A rotating hole 341 is opened on one side of the third rotating column 323 corresponding to the side of the clamping block 324. The interior of the three rotating columns 323 has a second rotating cavity 342. The third rotating block 344 is rotatably installed inside the second rotating cavity 342. A fourth rotating column 343 is fixedly installed at one end of the third rotating block 344. The fourth rotating column 343 is rotatably installed inside the rotating hole 341. One end of the fourth rotating column 343 is fixedly installed on the side of the clamping block 324. A third threaded hole 345 is opened on the side of the third rotating column 323. A fourth threaded column 346 is threadedly connected inside the third threaded hole 345.

[0023] More specifically, the first slider 211 slides vertically inside the first slide groove 112, and the first rotating column 232 drives the first rotating block 234 to rotate inside the first rotating cavity 233. After rotating to the appropriate position, the second rotating column 237 is inserted into the guide hole 235 so that the second threaded column 238 is threadedly connected to the threaded groove 236. Then, the first rotating column 232 is locked by the end face of the rotating handle 239 abutting against the end face of the first rotating column 232. The third rotating column 323 is rotated on the fourth rotating column 343 to adjust the angle of the third rotating column 323, thereby adjusting the angle of the first adjusting bracket 311 in the vertical direction.

[0024] like Figure 2 and Figure 5As shown, specifically, the first adjusting bracket 311 has rotating grooves 321 on both sides, the third rotating column 323 has a second rotating block 322 fixedly installed on its side, the two second rotating blocks 322 are respectively movably installed in the two rotating grooves 321, the first adjusting bracket 311 has a fixed block 331 fixedly installed on its side, the fixed block 331 has a second threaded hole 332 on its side corresponding to the position of the second rotating block 322, and the second threaded hole 332 is internally threaded with a third threaded column 333.

[0025] More specifically, rotating the third threaded post 333 causes the third threaded post 333 to press against the second rotating block 322 to fix the position of the first adjusting bracket 311 on the second rotating block 322, thereby adjusting the lateral angle of the first adjusting bracket 311.

[0026] like Figure 4 , Figure 5 and Figure 6 As shown, specifically, two third slide grooves 361 are opened on the inner side of the second adjusting bracket 312.

The second slider 362 is slidably installed inside the third slide groove 361. A second locking block 363 is fixedly installed at equal intervals on the inner side of the third slide groove 361. A limit block 364 is fixedly installed on the side of the second slider 362 corresponding to the position of the second locking block 363.

[0027] More specifically, when the fixed frame 353 moves downward, it causes the second slider 362 to move inside the third slide groove 361. When the limiting block 364 moves between the two second locking blocks 363, the limiting block 364 will be locked to restrict the movement of the fixed frame 353.

[0028] A construction method for a two-section adjustable bracket applied to a roof tile hanging system includes the following steps: Step 1: According to the roof design drawings and crossbar installation requirements, check and mark the installation baseline of each fixed bracket 111 and the preset height of the crossbar; Step 2: Select the corresponding installation program based on the detection results of Step 1; Step 2.1: If a single crossbar is to be installed, install the fixed bracket 111 independently according to the baseline, and adjust the height of each bracket to the preset value. Step 2.2: If multiple crossbars are installed continuously, install multiple fixed brackets 111 sequentially along the baseline and adjust them to the same height reference using the first slider 211. Step 3: Perform the installation and angle adjustment of the crossbar. Adjust the horizontal angle and pitch angle respectively by using the first rotating column 232 and the third rotating column 323 so that the second adjusting bracket 312 is aligned and supports the crossbar. Step 4: Perform cable laying and fixing operations. Place the cable on the support plate 352, and use the fixing bracket 353 to press down and cooperate with the pressing block 374 to clamp and fix the cable. Step 5: After the crossbar and cable are installed, the locking status of the fixing bracket 353 and the clamping stability of the cable are tested using a testing device. Step 5.1: If the mounting bracket 353 is locked in place and the cable is not loose, the installation is deemed qualified, and proceed to step 6. Step 5.2: If the fixing bracket 353 is not locked in place or the cable is loose, adjust the snap-fit ​​position of the fixing bracket 353 or readjust the downward pressure of the fixing bracket 353 until the locking state meets the requirements, then return to step 5 for re-inspection. Step 6: Conduct a final inspection and adjustment of the installed bracket to confirm that the fixed bracket 111 is not loose, all adjustment parts are securely locked, the crossbar is installed smoothly, and the cables are firmly fixed.

[0029] Working principle: The support base is fixed and the height is adjustable. The fixed support 111 is L-shaped and is fixed to the roof base surface by fasteners. The first slider 211 inside can slide up and down along the first sliding groove 112. During the sliding process, the constraint groove 212 and the constraint block 213 cooperate to ensure that the slider only moves in a vertical straight line. When the first slider 211 moves to the predetermined height, the rotating disk 223 drives the first threaded column 222 to be screwed into the first threaded hole 221, so that the compression pad 224 is deformed by pressure and tightly attached to the side wall of the fixed support 111. The height position is locked by the friction self-locking principle, realizing stepless adjustment and stable load bearing, horizontal and three-dimensional spatial angle adjustment. The first rotating column 232 is connected to the first rotating block 234 and the first rotating column 231 inside the connecting column 231. A rotating cavity 233 forms a rotating pair, which can rotate freely around the vertical axis, driving the first adjusting bracket 311 above to rotate horizontally to adapt to the direction of the crossbar. After adjustment, by screwing in the second rotating column 237, the second threaded column 238 meshes with the threaded groove 236 and presses the end face of the first rotating column 232 with the rotating handle 239 to achieve axial pre-tightening and locking. For three-dimensional spatial angle adjustment, the clamping block 324 forms a rotating pair with the third rotating column 323 through the fourth rotating column 343. The third rotating column 323 can rotate around the horizontal axis, changing the pitch angle of the first adjusting bracket 311 to adapt to the roof slope. The first adjusting bracket 311 is movably connected to the second rotating block 322 on the third rotating column 323 through the rotating groove 321, and through... Tightening the third threaded post 333 to press against the second rotating block 322 achieves lateral angle locking. The above-mentioned adjustment structure together realizes the alignment of the bracket in multiple degrees of freedom. The crossbar is installed and fixed synchronously with the cable. The second adjustment bracket 312 is U-shaped and is used to support the roof crossbar. After the crossbar is placed in place, the fixing frame 353 is pressed down, and the second sliders 362 on both sides move down along the third sliding groove 361. The limiting blocks 364 are sequentially inserted between the second locking blocks 363 to form a stepped anti-disengagement lock. During the pressing down of the fixing frame 353, its internal extrusion structure works synchronously, the crossbar is pressed, and the first locking block 355 is engaged in the corresponding slots 354 of the two fixing frames 353. Under the elastic force of the first spring 356, the crossbar is pressed up by the extrusion plate 357. A continuous elastic clamping force is applied to the surface to achieve flexible fixation and avoid damage from hard contact. The cable is clamped. The cable is pre-laid on the support plate 352. When the fixing frame 353 is pressed down, the bottom of the pressing block 374 is simultaneously pressed. The pressing block 374 drives the sliding block 372 to compress the second spring 373 and move downward. Together with the support plate 352, they form a clamping space to firmly clamp the cable. This linkage structure completes the horizontal bar fixing and cable laying simultaneously in a single operation, simplifying the construction process. The system is self-locking and stable. All adjustment parts adopt thread pre-tightening or elastic clamping methods and have self-locking capabilities. The first threaded column 222 forms a friction lock through the pressing pad 224. The second rotating column 237 and the third threaded column 333 adopt axial or radial clamping methods.The fixed frame 353 achieves mechanical anti-detachment through the engagement structure of the limiting block 364 and the second locking block 363. This multi-locking mechanism ensures the stability of the support under long-term loads and external forces such as wind vibration.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
