Description

Technical Field

[0001] The invention relates to the technical field of elevated floor construction, in particular to a residential elevated floor heat preservation and sound insulation structure. Background Art

[0002] Raised floor means that the supporting layer is at a certain distance from the bottom layer (bearing layer) of the building to form an overhead space to achieve the effect of heat preservation and sound insulation, and the supporting layer can be directly laid with floor or boards with enhanced heat preservation and sound insulation materials;

[0003] The existing support structure of the assembled raised floor is that the support layer and the bearing layer are often supported by multiple legs. The support plates are placed on the legs, the bolt holes are aligned, and then the legs and the support plates are fixed by locking nuts.

[0004] However, when assembling in this way, the bolt holes between the support plate and the support foot are often pre-opened in batches before the support plate and the support foot are installed for the convenience of installation. During installation, the support plate and the bolt holes on the support foot are aligned to complete the locking by means of locking nuts. However, in actual use, since the support foot and the bracket are not completely level when they are placed on the bearing layer, it is often necessary to perform horizontal measurements multiple times when the support plate is placed on the support foot and adjust the height of the support foot on the bracket multiple times to achieve the level of the support plate as much as possible. However, when multiple support plates are laid in sequence, the pre-opened bolt holes cannot achieve efficient installation, and during the installation process, the bolt holes and the bolts will deviate when they are aligned due to the unfixed horizontal height of the support plate and the support foot.

[0005] This deviation will affect the installation accuracy and efficiency of the bolt holes and bolts on the support plate and the support legs. Although the misalignment of the bolt installation holes on a single support plate and the support legs can be overcome by slightly adjusting the support leg height or the support plate placement angle, during the installation of support plates in batches, the subsequent installation work will be interfered with as multiple adjustments are made, resulting in extremely unstable installation convenience and efficiency of the subsequent support plates. After the installation is completed, the support legs and brackets are mostly self-locking in the threads, which will result in a larger load on the threads when the support plate is subjected to force, and the consistency and stability of the support legs and brackets will be reduced, as well as the sound insulation effect will be worse.

[0006] Based on this, the present invention designs a residential elevated ground thermal insulation and sound insulation structure to solve the above problems. Summary of the invention

[0007] The object of the present invention is to provide a residential elevated floor thermal insulation and sound insulation structure to solve the problems raised in the above background technology.

[0009] The two cams are connected with each other with a plurality of springs, and the two cams are connected with each other with a plurality of springs, and the two cams are connected with each other with a plurality of springs.

[0010] As a further solution of the present invention, a guide rod is slidably connected below the pressure rod, the bottom end of the guide rod is rotatably connected to the bracket, and the first spring is located inside the pressure rod and fixedly connected between the top end of the guide rod and the inner top wall of the pressure rod.

[0011] As a further scheme of the present invention, the locking group includes a slide groove, which is opened on the bracket, and the slide groove is gradually inclined and opened from right to left on both sides of the inner wall. The slider is located inside the slide groove and is slidably connected to the bottom wall of the slide groove. The slider is provided with two driving plates, and the driving plates are slidably connected to the bracket. The two driving plates can slide in the left and right directions along the side walls of the slider. The two driving plates are slidably connected with a latch in the front and rear directions. A second spring is fixedly connected between the two latches and the driving plates. The two latches are wedge-shaped, and the front side walls and rear side walls of the two latches are inclined and fit on both sides of the inner wall of the slide groove. An insert block is commonly provided on the left side of the two latches, and the end of the insert block is conical, and the insert block is fixedly connected to the bottom end of the slider.

[0012] As a further solution of the present invention, the two locking groups further include an active triggering group;

[0013] The active trigger group includes two trigger rods located at the front and rear of the bracket, four slots, four third springs and two push plates, the two trigger rods are located at the front and rear of the two sliders, the two trigger rods are slidably connected to the bracket in the front and rear directions, the left and right ends of the two trigger rods are slidably connected to limit blocks, the four slots are respectively opened at the front and rear of the two sliders, the two driving plates on the left and right sides are respectively located on the left and right sides of the two slots on the left and right sides, the four limit blocks are respectively located inside the four slots, the four third springs are respectively fixedly connected between the four driving plates and the side walls of the bracket, the two push plates are respectively fixedly connected to the bottom ends of the pressure rods, and the two push plates are tilted.

[0014] As a further solution of the present invention, positioning members are provided below the two push pieces, and the two positioning members are fixedly connected to the bracket.

[0015] As a further solution of the present invention, the ends of the two push pieces are rotatably connected with rollers or balls.

[0016] As a further solution of the present invention, a fourth spring is fixedly connected between the two trigger rods and the inner wall of the bracket.

[0017] As a further solution of the present invention, the height adjustment group includes a gear ring and two threaded rods, the two threaded rods are rotatably connected to the bracket, the bottom ends of the two threaded rods are provided with teeth that can engage with the gear ring, and the two threaded rods are threadedly connected to the adjustment block.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention limits the hand drill through the positioning hole and the positioning groove when drilling the mounting hole, and the positioning hole is concentric with the alignment hole, thereby ensuring that the mounting hole is also concentric. Therefore, when the locking nut is subsequently passed through the positioning hole, the mounting hole and the alignment hole, the nut and the mounting hole will not be misaligned due to the horizontal height of the support plate or the bracket, thereby improving the stability after installation and the consistency of the bracket, the support leg and the support plate, and avoiding vibration and noise caused by different installation precision when the bracket is subjected to force.

[0020] 2. When the height of the support leg and the adjustment block is adjusted, the support rod and the slider will change accordingly, and the position of the slider can be fixed by the locking group, so the height of the support leg will be fixed. After the floor and other insulation or noise reduction materials are laid on the subsequent support plate, the impact force and pressure applied to the support leg by the plate above will be shared and dispersed with the assistance of the support rod, and there is a gap between the support leg and the adjustment block, so that the impact force will not be transmitted downward directly. The oblique support provided by the support rod can change the direction of force from the traditional vertical upward force to the force on the left and right sides. Compared with the traditional method of adjusting the support leg and the support rod through the screw, the impact force will not be directly transmitted vertically downward to the bearing layer, and thus it can play a role in noise reduction again. In addition, the installation accuracy can be improved by aligning the mounting holes, alignment holes and positioning holes after installation, which can make the noise reduction effect of the bracket and the support leg more obvious.

[0038] See also Figure 1-15 The present invention provides a technical solution: a residential elevated floor insulation and sound insulation structure, comprising a support plate 1, a bracket 2 and a support leg 3, the support leg 3 is located directly above the bracket 2, an adjustment block 4 is arranged between the bracket 2 and the support leg 3, a height adjustment group is arranged below the adjustment block 4, and the height adjustment group is used to control the height of the adjustment block 4 from the bracket 2;

[0039] The support foot 3 is provided with a connecting groove 5 on the outside, and two connecting rods 6 are arranged inside the connecting groove 5. The bottom ends of the two connecting rods 6 are fixedly connected with positioning pieces 7. The two positioning pieces 7 are slidably connected to the adjustment block 4. The positioning pieces 7 are provided with driving grooves 8. The two driving grooves 8 are slidably connected with a pressure rod 9 inside. A first spring 10 is arranged below the pressure rod 9. The first spring 10 is located between the pressure rod 9 and the bracket 2. Two paddles 11 are fixedly connected to the side wall of the pressure rod 9. The inner wall of the driving groove 8 is provided with a transition surface 33. The plates 11 are slidably connected to the two driving grooves 8 respectively, the pressure rod 9 is provided with four positioning holes 12, the inner walls of the positioning holes 12 are provided with a plurality of positioning grooves 14, the support foot 3 is provided with four alignment holes 13, the positioning holes 12 are located directly above the alignment holes 13, the bottom end of the support foot 3 is rotatably connected to two support rods 15, the bottom ends of the two support rods 15 are rotatably connected to sliders 16, the two sliders 16 are slidably connected to the bracket 2, and a locking group is provided on one side of the slider 16, which is used to fix the slider 16.

[0040] like Figure 1-Figure 10 As shown:

[0041] After the bracket 2 and the supporting foot 3 are placed on the bearing layer, the distance between the bracket 2 and the supporting foot 3 is adjusted according to the height of the overhead layer to be determined. At this time, it is necessary to push the adjustment block 4 to rise relative to the bracket 2 through the height adjustment group. When the bracket 2 rises, the supporting foot 3 will be driven to rise, and at this time, the support rod 15 will drive the slider 16 to slide along the bracket 2 when the supporting foot 3 rises, and then a row of brackets 2 and supporting feet 3 are placed on the bearing layer, and then the two ends of the rear of the support plate 1 are first placed to a position that fits above the two supporting feet 3 at the rear, and in the subsequent placement process of the support plate 1, the adjacent support plates 1 must be ensured to be in contact, and after the two ends of the rear of the support plate 1 are placed on the two supporting feet 3 at the rear, the supporting feet 3 are placed below the two ends of the front of the support plate 1 that are in the empty state (one supporting foot 3 is in the middle position of the ends of four adjacent supporting plates 1), when the four corners of the support plate 1 are supported by the supporting feet 3, it is necessary to calibrate the horizontal height, and after the horizontality is calibrated, the subsequent hole opening work can be carried out;

[0042] When the drill bit is aligned with the alignment hole 13, the positioning groove 14 will be aligned with the adjustment block 12, and the positioning groove 14 will be aligned with the adjustment block 12 to prevent the drill bit from being disengaged. The inner part of 4 slides down and compresses the first spring 10 downward. As the hand drill presses the pressure rod 9 downward, the drill bit will gradually approach the support plate 1 and punch the support plate 1. When the drill bit passes through the support plate 1, the drilling of the mounting hole 32 is completed. Then, the drill bit can be stopped after it is felt that it has passed through the support plate 1. At this time, the support plate 1 is in contact with the support foot 3, thereby ensuring that the mounting hole 32 is concentric with the alignment hole 13 and the positioning hole 12. Therefore, when the locking nut is subsequently passed through the positioning hole 12, the mounting hole 32 and the alignment hole 13, the nut and the mounting hole 32 cannot be aligned due to the horizontal height of the support plate 1 or the bracket 2, thereby improving the stability after installation and the consistency of the bracket 2, the support foot 3 and the support plate 1, thereby improving the consistency of the overall support plate 1 with multiple brackets 2 and the support foot 3, avoiding vibration and noise caused by different installation precision when the bracket 2 is subjected to force, and avoiding large-scale shaking;

[0043] When the mounting holes 32 are drilled, lift the hand drill and then drill holes in the support plates 1 at the remaining positions. When the drilling of a row of support plates 1 is completed (a row can be understood as a horizontal or vertical arrangement direction, which will change differently in different installation areas), the support plates 1 of the next row need to be laid first. After the placement of the next row is completed, you can start drilling holes in the support plates 1 of this row. After the support legs 3 are surrounded by four support plates 1, you can start the fixing work. At this time, directly pass the locking nut through the positioning hole 12 (the positioning hole 12 is larger than the locking nut), and then drive the bottom end of the locking nut into The ends of the four support plates 1 can be fixed inside the mounting holes 32 and the alignment holes 13. Similarly, the subsequent support plates 1 are fixed in the same manner, but at this time, the height of the pressure rod 9 is still higher than the top of the support plate 1 under the action of the first spring 10. When the ends of the four support plates 1 around all the legs 3 are fixed by the locking nuts, the overall laying is completed. When laying floors or other panels on the subsequent support plates 1, the pressure rod 9 can be pressed down to the limit by gravity. At this time, the top of the pressure rod 9 will be at a height lower than or equal to the top of the support plate 1, and will not affect the horizontality.

[0044] After the mounting holes 32 on the four support plates 1 around the support foot 3 are fixed by the locking nuts, the pressure rod 9 is rotated first. At this time, the pressure rod 9 will drive the paddle 11 to contact the transition surface 33 and move inside the driving groove 8 under the guidance of the transition surface 33. At this time, the paddle 11 will push the positioning piece 7 to drive the connecting rod 6 to move. At this time, the positioning piece 7 will slide along the adjusting block 4, and the connecting rod 6 will slide out of the connecting groove 5. When the connecting rod 6 is inside the connecting groove 5, the adjusting block 4 can drive the support foot 3 to rise and fall. However, after the connecting rod 6 is separated from the connecting groove 5, the adjusting block 4 is separated from the support foot 3. After that, the pressure rod 9 rises under the elastic reset action of the first spring 10, but the paddle 11 will contact the inner wall of the driving groove 8 at this time, and can still block the reset of the positioning piece 7. Therefore, when the connecting rod 6 is outside the connecting groove 5, the support foot 3 can only be supported by the support rod 15 at this time. At this time, there is a certain distance between the adjusting block 4 and the support foot 3 to prevent force transmission.

[0045] The present invention, when the height of the support leg 3 and the adjusting block 4 are adjusted, the support rod 15 and the slider 16 will follow the change, and the position of the slider 16 can be fixed by the locking group, so the height of the support leg 3 will be fixed. Then, after the floor or other heat-insulating or noise-reducing material plates are laid on the subsequent support plate 1, the impact force and pressure applied to the support leg 3 by the plate above will be shared and dispersed with the assistance of the support rod 15, and there is a gap between the support leg 3 and the adjusting block 4, so that the impact force will not be transmitted downward. The oblique support provided by the support rod 15 can convert the force direction from the traditional vertical upward force to the force on the left and right sides. Compared with the traditional method of adjusting the support leg 3 and the support rod 15 by screws, the impact force will not be directly transmitted vertically downward to the bearing layer, thereby playing a role in noise reduction again, and the mounting hole 32, the alignment hole 13 and the positioning hole 12 after installation can improve the installation accuracy, so that the noise reduction effect of the bracket 2 and the support leg 3 can be more obvious.

[0046] A guide rod 22 is slidably connected below the pressure rod 9 , and the bottom end of the guide rod 22 is rotatably connected to the bracket 2 . The first spring 10 is located inside the pressure rod 9 and fixedly connected between the top end of the guide rod 22 and the inner top wall of the pressure rod 9 .

[0047] like Figure 3 and Fig. 9 As shown:

[0048] After the pressure rod 9 is pressed down, it will slide along the guide rod 22 and compress the first spring 10. The guide rod 22 can guide the pressure rod 9 and limit its position to prevent the pressure rod 9 from being separated from the preset position and causing eccentricity among the positioning hole 12, the alignment hole 13 and the mounting hole 32.

[0049] The locking group includes a slide groove 17, which is opened on the bracket 2. The slide groove 17 is gradually inclined and opened from right to left on both sides of the inner wall. The slider 16 is located inside the slide groove 17 and is slidably connected to the inner bottom wall of the slide groove 17. Two driving plates 19 are provided on the slider 16. The driving plates 19 are slidably connected to the bracket 2. The two driving plates 19 can slide in the left and right directions along the side walls of the slider 16. The two driving plates 19 are slidably connected with a bayonet 18 in the front and rear directions. A second spring 20 is fixedly connected between the two bayonet pins 18 and the driving plates 19. The two bayonet pins 18 are wedge-shaped. The front and rear side walls of the two bayonet pins 18 are inclined and fit on both sides of the inner wall of the slide groove 17. An insert block 21 is commonly provided on the left side of the two bayonet pins 18. The end of the insert block 21 is tapered, and the insert block 21 is fixedly connected to the bottom end of the slider 16.

[0050] like Figure 10-Figure 14 As shown:

[0051] When the height adjustment group drives the adjustment block 4 and the support leg 3 to rise, the support leg 3 rises with the slider 16 to slide inside the slide groove 17 through the support rod 15. At this time, the plug block 21 will slide on the bottom wall of the slide groove 17. The slider 16 will drive the drive plate 19 to move when it moves. At this time, the drive plate 19 is on the rightmost side of the slider 16, so when the slider 16 moves, it will pull the drive plate 19 to slide along the bracket 2. When the height of the support leg 3 is determined, the latch 18 and the drive plate 19 are also at a certain distance from the slider 16 and the plug block 21. At this time, it is necessary to calibrate the horizontal height of the support plate 1. If the support leg 3 and the adjustment block 4 need to be lowered, then The drive adjustment block 4 and the support leg 3 can be lowered, and the slider 16 will move to the right at this time. At this time, the side wall of the latch 18 is in contact with the side wall of the slide groove 17, and the second spring 20 pulls the latch 18 to make the side wall of the slide groove 17 have a certain friction force. Therefore, when the slider 16 moves to the right, it will not drive the drive plate 19 to move. After the horizontal height is calibrated, the drilling of the installation hole 32 can be started. After the drilling is completed, it can be fixed by the locking nut. After the fixing is completed, the pressure rod 9 can be rotated to a certain angle, so that the paddle 11 pushes the positioning plate 7 to drive the connecting rod 6 to the outside of the connecting groove 5.

[0052] Then, the two driving plates 19 can be manually pushed toward the insert block 21 to the limit. During this process, the side wall of the latch 18 will always move in contact with the side wall of the slide slot 17, and the left end of the slide slot 17 will gradually open. At this time, the second spring 20 will also be gradually stretched. After the two latch pins 18 are in contact with the insert block 21, the insert block 21 will contact the middle of the two latch pins 18, and at this time, the insert block 21 will open the latch pin 18, thereby preventing the latch pin 18 from sliding along the driving plate 19. In the subsequent support plate 1 is laid on the bottom plate or other plates and generates impact force when people walk or install, the force on the support leg 3 will be shared by the support rod 15, and the support rod 15 will have a tendency to drive the slider 16 to slide to the right, but at this time the insert block 21 is inserted between the two bayonet pins 18, and the two bayonet pins 18 are restricted by the inner wall of the slide groove 17 which gradually opens to the left and cannot move, so the slider 16 will be restricted in this position, and then the downward impact force will be converted into left and right impact when the force is applied, reducing the impact on the bearing layer, thereby reducing noise.

[0053] The two locking groups also include an active trigger group;

[0054] The active trigger group includes two trigger rods 23 located at the front and rear of the bracket 2, four slots 25, four third springs 26 and two push pieces 27. The two trigger rods 23 are located at the front and rear of the two sliders 16. The two trigger rods 23 are slidably connected to the bracket 2 in the front and rear directions. The left and right ends of the two trigger rods 23 are slidably connected to the limiting blocks 24. The four slots 25 are respectively opened at the front and rear of the two sliders 16. The two driving plates 19 on the left and right sides are respectively located on the left and right sides of the two slots 25 on the left and right sides. The four limiting blocks 24 are respectively located inside the four slots 25. The four third springs 26 are respectively fixedly connected between the four driving plates 19 and the side walls of the bracket 2. The two push pieces 27 are respectively fixedly connected to the bottom ends of the pressure rods 9, and the two push pieces 27 are tilted.

[0055] like Figure 10-Figure 14 As shown:

[0056] When the height of the support leg 3 is adjusted, the slider 16 drives the plug block 21 to move and pulls the driving sheet 19 to slide along the bracket 2. At this time, the third spring 26 is gradually stretched (the third spring 26 is compressed before being stretched, that is, it is in a state of elastic release), and the limit block 24 is in the slot 25, so that the bayonet 18 has a certain distance from the plug block 21 and will not be pushed by the elasticity of the third spring 26. When the support leg 3 is raised, the slider 16 moves to the left and drives the limit block 24 to move together. At this time, the limit block 24 will slide along the trigger rod 23.

[0057] After the locking nut fixes the four support plates 1, it means that the support leg 3 has also completed the height determination. However, at this time, the latch 18 is at a certain distance from the plug block 21, but has not been driven in the direction of the plug block 21. At this time, the pressure rod 9 can be manually pressed directly downward. When the pressure rod 9 descends, the paddle 11 will slide and descend inside the driving groove 8. At this time, the first spring 10 will also be compressed, and the push piece 27 will follow the decline. After the pressure rod 9 is pressed down to the limit, the pressure rod 9 is rotated, and the pressure rod 9 will drive the guide rod 22 to rotate on the bracket 2, and the push piece 2 7 is inclined, so when it rotates, the originally inclined push piece 27 will push the trigger rod 23 to slide along the side wall of the bracket 2. At this time, the trigger rod 23 will drive the limit block 24 to be pulled out from the inside of the slot 25, and then the elastic relaxation of the third spring 26 will push the drive piece 19 to drive the latch 18 to move toward the insertion block 21 until the two latches 18 contact the insertion block 21. Although the third spring 26 still has a leftward pushing force at this time, the support leg 3 has been fixed to the support plate 1 at this time, so this part of the force is useless at this time and will not cause any impact.

[0058] Positioning members 28 are disposed below the two push pieces 27 , and the two positioning members 28 are fixedly connected to the bracket 2 .

[0059] like Fig.14 , Fig.14 as well as Fig.15 As shown:

[0060] When the pressure rod 9 is pressed down to the limit, the pressure rod 9 can be directly released after being rotated. At this time, although the pressure rod 9 has a tendency to return upward under the relaxation of the first spring 10, the push piece 27 will be blocked by the positioning member 28 and cannot rise, thereby completing the locking of the pressure rod 9 in this position.

[0061] The ends of the two push pieces 27 are rotatably connected with rollers or balls.

[0062] A fourth spring 29 is fixedly connected between the two trigger rods 23 and the inner wall of the bracket 2 .

[0063] like Fig.14 As shown in the figure:

[0064] The ball and the roller are prior arts, and their purpose is to reduce the friction between the push piece 27 and the trigger rod 23. They are common knowledge, so they are not described in detail. The fourth spring 29 gives the trigger rod 23 a reset function after the third spring 26 is elastically released when the push piece 27 pushes the trigger rod 23. However, at this time, the trigger rod 23 only has the force to drive the limit block 24 toward the direction of the slot 25. However, the trigger rod 23 and the limit block 24 and the latch 18, the drive plate 19 and the third spring 26 will definitely be blocked by each other, so that the trigger rod 23 cannot move to the initial position. Therefore, the role of the fourth spring 29 at this time is to form a support for the trigger rod 23, so that the trigger rod 23 will not shake at will to produce noise.

[0065] The height adjustment group includes a gear ring 30 and two threaded rods 31. The two threaded rods 31 are rotatably connected to the bracket 2. The bottom ends of the two threaded rods 31 are provided with teeth that can mesh with the gear ring 30. The two threaded rods 31 are threadedly connected to the adjustment block 4.

[0066] like Figure 3 As shown:

[0067] The threaded rod 31 is rotated by the engagement of the rotating gear ring 30 with the teeth on the threaded rod 31, thereby causing the adjusting block 4 to rise or fall.
