Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to an anti-cracking structure for a basement exterior wall. Background Art

[0002] Shopping malls and residential areas often use basements as parking lots. However, in the engineering practice of large basement construction, due to the large shrinkage of concrete, when the soil layer around the basement is backfilled, the outer wall of the basement will be squeezed by the external soil layer. When the outer wall of the basement is subjected to soil compression for a long time, cracks will appear in the basement. At this time, external groundwater can easily seep into the basement through the cracks, so it is necessary to perform anti-crack operations on the outer wall of the basement.

[0003] Existing Figure 1 The exhibit demonstrates a crack-resistant structure for a basement exterior wall, comprising an exterior wall body 1 and a mounting bar 2 mounted on one side of the exterior wall body 1. The mounting bar 2, located near the lower end of the exterior wall body 1, is threaded with multiple mounting screws 21 that are inserted into the exterior wall body 1 and into the ground. The mounting bar 2 can partially channel pressure applied to the exterior wall body 1 onto the mounting bar 2, thereby preventing the wall from cracking.

[0004] The mounting strip 2 is fixed to the wall and the ground by fixing screws 41. In order to ensure the stability of the mounting strip 2 on the exterior wall and the ground, multiple mounting screws 21 need to be installed, which makes the installation process complicated and inconvenient to install the anti-cracking structure. Summary of the Invention

[0005] In order to facilitate the installation of the anti-cracking structure, the present application provides an anti-cracking structure for the basement exterior wall.

[0006] This application provides a basement exterior wall crack-resistant structure, which adopts the following technical solutions:

[0007] A basement exterior wall anti-crack structure comprises an exterior wall body and an anti-crack strip disposed on one side of the exterior wall body, wherein the anti-crack strip is provided with a plurality of mounting assemblies, wherein the mounting assemblies comprise two fixing screws threadedly connected to the anti-crack strip, wherein the sliding directions of the two fixing screws are perpendicular to each other;

[0008] The anti-crack strip is also rotatably connected to a control ring corresponding to the fixed screw one by one, and the anti-crack strip is provided with a connecting component that drives the adjacent control ring to rotate when the control ring rotates; the fixed screw is provided with a fixing component that enables the control ring to drive the fixed screw to rotate, and the fixed screw is rotatably connected to a control rod, and the fixed screw is provided with a plurality of plug-in rods, and the sliding direction of the plurality of plug-in rods is perpendicular to the sliding direction of the fixed screw, and the fixed screw is provided with a pushing component that controls the plug-in rod to move toward or away from the fixed screw when the control rod rotates, and the anti-crack strip is provided with an unlocking structure for releasing the fixed screw and the control ring when part of the fixed screw extends out of the anti-crack strip, and a rotating structure that controls the control rod to drive the control rod to rotate.

[0009] By adopting the above technical solution, the anti-cracking strip is installed on one side of the exterior wall body, and the control ring is rotated. At this time, under the action of the fixing component, the control ring drives the fixing screw to rotate. At the same time, under the action of the connecting component, the adjacent fixing screw also rotates. The fixing screw rotates while moving toward the ground or the exterior wall body until the fixing screw is inserted into the ground or the exterior wall body, and then the control ring continues to be rotated. At this time, with the cooperation of the unlocking component and the rotating structure, the control ring can drive the control rod to rotate. Under the action of the pushing component, the plug-in rod slides in the direction away from the fixing screw. The connection strength between the anti-cracking strip and the ground and the anti-cracking strip and the exterior wall body is strengthened by the plug-in rod, and the number of fixing screws can be appropriately reduced, thereby achieving the effect of convenient installation of the anti-cracking structure.

[0010] Optionally, the control ring is located between the fixed screw and the control rod, the fixed screw is provided with a control groove for the control ring to rotate, the fixed assembly includes a plurality of fixed blocks sliding on the control ring and a fixed spring arranged on the control ring, the wall of the control groove is provided with a fixed groove for inserting the fixed block, the fixed block can slide in the fixed groove along the axis direction of the fixed screw, and the fixed spring always gives the fixed block an elastic force to slide toward the direction close to the fixed groove.

[0011] By adopting the above technical solution, under the action of the elastic force of the fixed spring, the fixed block can slide toward the fixed groove until the fixed block is inserted into the fixed groove, and the control ring starts to rotate. At this time, with the cooperation of the fixed block and the wall of the fixed groove, the control ring can drive the fixed screw to rotate.

[0012] Optionally, the connecting assembly includes a first rotating gear, a second rotating gear, a third rotating gear and a fourth rotating gear, the first rotating gear is sleeved on one of the control rings, the second rotating gear is sleeved on the other control ring, the third gear is meshed with the second rotating gear, and the rotation axis direction of the third rotating gear is parallel to the rotation axis direction of the second rotating gear, the first rotating gear is meshed with the fourth rotating gear, the axis direction of the first rotating gear is perpendicular to the axis direction of the fourth rotating gear, and the fourth rotating gear rotates coaxially with the third rotating gear.

[0013] By adopting the above technical solution, when one of the control rings rotates, since the first rotating gear and the fourth rotating gear are engaged, and the second rotating gear and the third rotating gear are engaged, when one of the control rings rotates, the other control ring will also rotate with the cooperation of the third rotating gear and the fourth rotating gear.

[0014] Optionally, the pushing assembly includes a pushing gear sleeved on the control rod and a pushing rack arranged on the plug-in rod, and the pushing gear is meshed with the pushing rack.

[0015] By adopting the above technical solution, when the control rod rotates, the pushing gear can drive the pushing rack to slide, and the pushing rack can drive the plug rod to slide toward or away from the fixed screw rod.

[0016] Optionally, the anti-crack strip is provided with an installation groove for installing a fixing screw, and the unlocking structure is an inclined guide surface provided on the wall of the fixing groove, and the inclined guide surface is for the fixing block to abut and control the fixing block to slide away from the fixing groove.

[0017] By adopting the above technical solution, when the fixed screw slides away from the anti-crack strip and part of the fixed screw extends out of the anti-crack strip, the fixed block abuts against the inclined guide surface. At this time, under the action of the inclined guide surface, the fixed block is pushed out of the fixed groove. At this time, the rotation of the control ring cannot drive the fixed screw to rotate.

[0018] Optionally, the rotating structure is a rotating groove provided on the outer peripheral side of the control rod, and the fixing block can be inserted into the rotating groove when the fixing block slides in a direction away from the fixing groove.

[0019] By adopting the above technical solution, when the fixed block slides away from the fixed groove, the side of the fixed block away from the fixed groove can be inserted into the rotating groove. At this time, with the cooperation of the fixed block and the rotating groove, the rotation of the control ring can drive the control rod to rotate.

[0020] Optionally, the fixing screw is provided with a reset component for controlling the fixing block to be inserted into the fixing groove when the plug rod is received into the fixing screw.

[0021] By adopting the above technical solution, when the anti-cracking strip needs to be removed, the control ring is rotated in the opposite direction. At this time, the connecting rod can move toward the fixed screw until the connecting rod is retracted into the fixed screw. At this time, under the action of the reset assembly, the fixed block can be inserted into the fixed groove. Continue to rotate the control ring, and the control ring can drive the fixed screw to be retracted into the anti-cracking strip.

[0023] By adopting the above technical solution, when the control rod drives the plug rod to slide toward the plug rod, the reset rod pushes the first connecting rod to move under the action of the first guide inclined surface, and the pushing block abuts against the second guide inclined surface. The pushing block can push the fixed block to slide in the direction away from the rotation groove until the reset block enters the fixed groove. At this time, the control ring, the fixed screw, and the control rod rotate synchronously. When the fixed screw slides a distance toward the anti-crack strip, the fixed block no longer abuts against the inclined guide surface. The fixed block can enter the fixed groove under the action of the fixing assembly. At this time, the control ring only drives the fixed screw to rotate.

[0024] Optionally, a guide groove for the sliding movement of the fixed block is provided on the wall of the rotating groove.

[0025] By adopting the above technical solution, since the control ring and the fixing screw are still rotating when the fixed block moves away from the fixed groove, the fixed block is not aligned with the rotating groove at this time, and the guide groove is used to buffer the fixed block, thereby reducing damage to the fixed block when the fixed block is stuck in the rotating groove.

[0026] Optionally, a control motor and a mounting plate for the control motor are installed on one side of the anti-crack strip, and a mounting frame is provided at the upper end of the anti-crack strip. The mounting frame includes two mounting strips, and the mounting strips are provided with sliding grooves for the mounting plate to slide. The control motor is provided with a control component that causes the control motor to drive the control ring to rotate when the mounting plate enters the sliding groove.

[0027] By adopting the above technical solution, the mounting plate is inserted into the sliding groove, and then the control motor is controlled by the control component to drive the control ring to rotate.

[0028] In summary, this application has at least one of the following beneficial effects:

[0029] 1. A control motor is installed on the mounting frame. When the control motor is started, the control ring starts to rotate. At the same time, under the action of the connecting assembly, the adjacent control rings also rotate, and the control ring drives the fixed screw to rotate. Both fixed screws move away from the anti-crack strip. When part of the fixed screw extends out of the anti-crack strip, the control ring can be connected to the control rod. At this time, the control ring is continued to rotate, and the plug-in rod can be inserted into the exterior wall body or the ground to complete the installation of the anti-crack strip. The plug-in rod strengthens the connection strength between the anti-crack strip and the ground, and between the anti-crack strip and the exterior wall body. The number of fixed screws can be appropriately reduced, which can achieve the effect of convenient installation of the anti-crack structure.

[0030] 2. Rotate the control ring in the opposite direction, and the plug-in rod can be retracted into the fixed screw. Continue to rotate the control ring, and the fixed screw can be retracted into the anti-crack strip, making it easy to disassemble the anti-crack structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following is combined with Figure 2-6 This application is described in further detail.

[0039] The embodiment of the present application discloses a crack-resistant structure for the exterior wall of a basement.

[0040] Reference Figure 2 and Figure 3 The anti-cracking structure of the basement exterior wall includes an exterior wall body 1 and an anti-cracking strip 3, wherein the anti-cracking strip 3 is attached to the outside of the exterior wall body 1, and a number of mounting components 4 are installed on the anti-cracking strip 3. The several mounting components 4 are arranged along the length direction of the anti-cracking strip 3, and the mounting components 4 include two fixing screws 41. The two fixing screws 41 are perpendicular to each other, and a thread groove 31 is provided on the anti-cracking strip 3 to match the threaded portion of the fixing screws 41. When the two fixing screws 41 rotate, one of the fixing screws 41 moves toward or away from the exterior wall body, and the other fixing screw 41 moves toward or away from the ground.

[0041] Reference Figure 3A control ring 5 corresponding to the fixed screw 41 is also installed on the anti-crack strip 3. The axial direction of the control ring 5 coincides with the axial direction of the fixed screw 41. A placement groove 32 for the control ring 5 is provided on the anti-crack strip 3. A rotating ring 51 is provided on the control ring 5, and a limiting ring 52 is provided on the outer circumference of the rotating ring 51. In this embodiment, the rotating ring 51 and the limiting ring 52 are integrally provided. A first rotating groove 33 for the rotating ring 51 to rotate is provided on the wall of the placement groove 32, and a second rotating groove 34 for the limiting ring 52 to rotate is provided on the wall of the first rotating groove 33. With the cooperation of the rotating ring 51 and the first rotating groove 33, the control ring 5 can rotate in the anti-crack strip 3. With the cooperation of the limiting ring 52 and the second rotating groove 34, the possibility of the control ring 5 moving along the axial direction of the control ring 5 is reduced, thereby improving the stability of the rotation of the control ring 5.

[0042] Reference Figure 3 , a connecting assembly 7 is also installed on the anti-crack strip 3, and the connecting assembly 7 includes a first rotating gear 71, a second rotating gear 72, a third rotating gear 73 and a fourth rotating gear 74. The first rotating gear 71 is fixedly sleeved on the outer circumference of one of the control rings 5 ​​in the mounting assembly 4, and the second rotating gear 72 is fixedly sleeved on the outer circumference of the other control ring 5 in the mounting assembly 4. The third rotating gear 73 is meshed with the second rotating gear 72, and the third rotating gear 73 is meshed with the second rotating gear 72, and the fourth rotating gear 74 is also meshed with the first rotating gear 71. The axial direction of the third rotating gear 73 is parallel to the axial direction of the second rotating gear 72, and the axial direction of the fourth rotating gear 74 is perpendicular to the axial direction of the first rotating gear 71. A movable groove 35 is provided on the anti-crack strip 3 for the first rotating gear 71, the second rotating gear 72 to rotate with the third rotating gear 73 and the fourth rotating gear 74.

[0043] Reference Figure 3 The third rotating gear 73 is provided with a rotating shaft 731, which is connected to the third rotating gear 73 and the fourth rotating gear 74 via an axis. The movable groove 35 has an axis groove 36 formed on the wall thereof for the rotating shaft 731 to rotate. When one of the control rings 5 ​​rotates, the first rotating gear 71, the second rotating gear 72, and the third rotating gear 73 can rotate synchronously with the cooperation of the third rotating gear 73, thereby achieving the effect of simultaneously rotating the other control ring 5.

[0044] Reference Figure 4 and Figure 5A control groove 411 for the control ring 5 to rotate is defined on the upper end surface of the fixed screw 41. Several fixing assemblies 6 are also mounted on the fixed screw 41. These assemblies 6 include a fixing block 61 and a fixing spring 62. A movable groove 53 is defined on the control ring 5 for the fixing block 61 to slide. A contact block 611 is provided on the sidewall of the fixing block 61. A contact groove 54 is defined on the wall of the movable groove 53 for the contact block 611 to slide. One end of the fixing spring 62 abuts against the contact block 611, while the other end of the fixing spring 62 abuts against the wall of the contact groove 54 close to the axis of the control ring 5. A fixing groove 412 is defined on the wall of the control groove 411 for the fixing block 61 to insert into. Under the elastic force of the fixing spring 62, the fixing block 61 slides toward the fixing groove 412 until it is inserted into the fixing groove 412. At this point, the rotation of the control ring 5 drives the fixed screw 41 to rotate.

[0045] Reference Figure 4 and Figure 5 The fixing groove 412 can also allow the fixing block 61 to slide along the axial direction of the control ring 5. When the control ring 5 rotates, the fixing block 61 is pushed into the fixing groove 412 by the elastic force of the fixing spring 62, and the centrifugal force generated when the control ring 5 rotates presses the fixing block 61 against the wall of the fixing groove 412. At the same time, the fixing screw 41 cooperates with the thread groove 31. At this time, the fixing screw 41 can move toward or away from the anti-crack strip 3.

[0046] Reference Figure 4 A control rod 8 is also installed in the fixed screw 41. The control rod 8 is a round rod. An operating groove 413 for rotating the control rod 8 is provided on the fixed screw 41. The axial direction of the control rod 8 coincides with the axial direction of the control ring 5. A rotating ring 81 is provided on the outer peripheral side of the control rod 8. A rotating groove 414 for rotating the rotating ring 81 is provided on the wall of the operating groove 413. With the cooperation of the rotating ring 81 and the rotating groove 414, the control rod 8 can rotate in the fixed screw 41.

[0047] Reference Figure 4 and Figure 5 The control ring 5 is clamped by the fixed screw 41 and the control rod 8, and an unlocking structure 9 is installed on the fixed screw 41. The unlocking structure 9 is an inclined guide surface 91 provided on the wall of the fixed groove 412. When the fixed screw 41 moves in the direction away from the anti-crack strip 3, the fixed block 61 can move toward the inclined guide surface 91 until the fixed block 61 abuts against the inclined guide surface 91. At this time, under the action of the inclined guide surface 91, the fixed block 61 slides in the direction away from the fixed groove 412 until the fixed block 61 falls off the fixed groove 412. At this time, the rotation of the control ring 5 cannot drive the fixed screw 41 to rotate, thereby unlocking the connection between the control ring 5 and the fixed screw 41.

[0048] Reference Figure 4 and Figure 5 A rotating structure 10 is also installed on the fixed screw 41. The rotating structure 10 is a rotating groove 101 opened on the outer peripheral side of the control rod 8. When the fixed block 61 moves away from the fixed groove 412, the end of the fixed block 61 away from the fixed groove 412 can be inserted into the rotating groove 101. At this time, the rotation of the control ring 5 can drive the control rod 8 to rotate.

[0049] Reference Figure 5 and Figure 6 Since the fixed block 61 does not slide instantly when it moves away from the fixed groove 412, and there is a movement process in the middle, if the fixed block 61 is directly inserted into the rotating groove 101, it may cause damage to the fixed block 61 or the notch of the rotating groove 101. Therefore, a guide groove 102 for the sliding of the fixed block is provided on the wall of the rotating groove 101. The guide groove 102 is used to buffer the fixed block 61, thereby reducing damage to the fixed block 61 during the process of the fixed block 61 being stuck in the rotating groove 101.

[0050] Reference Figure 6 The fixed screw 41 is also mounted with a plurality of plug-in rods 11, which are evenly arranged around the axis of the control rod 8. In this embodiment, two plug-in rods 11 are used as an example. A plug-in slot 415 is formed on the wall of the operating slot 413, allowing the plug-in rods 11 to slide toward or away from the fixed screw 41. A pushing assembly 12 is also mounted on the fixed screw 41. The pushing assembly 12 includes a pushing gear 121 and a plurality of pushing racks 122. The pushing gear 121 and the pushing racks 122 are meshed with each other, wherein the pushing racks 122 are fixedly mounted on the side of the plug-in rod 11 close to the control rod 8. The pushing gear 121 is sleeved on the control rod 8. When the control rod 8 rotates, the pushing gear 121 and the pushing racks 122 cooperate to allow the plug-in rod 11 to slide toward or away from the fixed screw 41.

[0051] Reference Figure 5 and Figure 6A reset block 13 is installed on the fixed block 61, and a translation groove 612 for the reset block 13 to slide is opened on the fixed block 61. There is a large friction force between the reset block 13 and the translation groove 612. A reset assembly 14 is also installed on the fixed screw 41. The reset assembly 14 includes a reset rod 141, a first connecting rod 142, a second connecting rod 143 and a plurality of pushing blocks 144, wherein the reset rod 141 is fixedly installed on one of the plug-in rods 11, and a reset groove 82 for the reset rod 141 to enter is provided on the control rod 8. The first connecting rod 142 slides vertically on the control rod 8, and the second connecting rod 143 is vertically arranged on the first connecting rod 142. A connecting groove 83 for the second connecting rod 143 to slide is opened on the control rod 8. A first guide inclined surface 1421 for the reset rod 141 to abut and control the first connecting rod 142 to slide in the direction away from the reset rod 141 is provided on the first connecting rod 142. The pushing block 144 corresponds one-to-one to the fixed block 61. A pushing groove 84 is provided on the control rod 8 for the pushing block 144 to slide. The pushing groove 84 is connected to the connecting groove 83. A second guide inclined surface 1441 is provided on the pushing block 144 for the second connecting rod 143 to abut and control the pushing block 144 to slide toward the reset block 13.

[0052] Reference Figure 5 and Figure 6 When the control rod 8 rotates in the opposite direction, the reset rod 141 can move toward the first connecting rod 142 until the plug-in rod 11 is received in the fixed screw 41. At this time, the reset rod 141 can abut against the first guide inclined surface 1421. Under the action of the first guide inclined surface 1421, the first connecting rod 142 and the second connecting rod 143 can slide in the direction away from the reset rod 141. Under the action of the second guide inclined surface 1441, the pushing block 144 pushes the reset block 13 to slide toward the fixed groove 412. When the reset block 13 enters the fixed groove 412, the control ring 5, the fixed screw 41 and the control rod 8 rotate synchronously. The fixed screw 41 can slide toward the anti-crack strip 3 until the fixed block 61 no longer abuts against the inclined guide surface 91.

[0053] Reference Figure 3 and Figure 5 When the fixing block 61 falls off the rotating groove 101, the control ring 5 only drives the fixing screw 41 to rotate until the fixing screw 41 is received in the anti-crack strip 3, releasing the installation of the anti-crack strip 3 and the exterior wall body 1 and the ground.

[0054] Reference Figure 3 and Figure 4A control motor 15 and a mounting plate 16 are also installed at the upper end of the anti-crack strip 3, wherein the control motor 15 is fixedly mounted on the mounting plate 16, a motor slot 37 is provided at the upper end of the anti-crack strip 3, and a mounting frame 17 is installed at the motor slot 37 of the anti-crack strip 3. The mounting frame 17 includes two vertically arranged mounting rods 171, and a sliding groove 1711 is provided on the mounting rod 171 for the mounting plate 16 to slide.

[0055] Reference Figure 3 and Figure 4 A control board 18 is welded to the control ring 5 on the side near the mounting bracket 17. A control assembly 19 is also mounted on the control motor 15. The control assembly 19 includes a control shaft 191 and a control block 192. The control shaft 191 is welded to the output shaft of the control motor 15, and the control block 192 is welded to the outer periphery of the control shaft 191. The control board 18 has a first engaging groove 181 for the control shaft 191 to be inserted into, and a second engaging groove 182 is formed on the wall of the first engaging groove 181 for the control block 192 to be inserted into. When the mounting plate 16 slides within the sliding groove 1711, the control shaft 191 can enter the first engaging groove 181, and the control block 192 can enter the engaging groove 83. At this time, the control motor 15 is started, and the control shaft 191 drives the control block 192 to rotate. With the cooperation of the control block 192 and the wall of the engaging groove 83, the control motor 15 drives the control ring 5 to rotate.

[0056] The implementation principle of the anti-cracking structure of the basement exterior wall in the embodiment of the present application is as follows:

[0057] The control motor 15 is installed on the mounting bracket 17 and started. Under the action of the control assembly 19, the control ring 5 starts to rotate. At the same time, with the cooperation of the third rotating gear 73, the first rotating gear 71 can drive the third rotating gear 73 to rotate, and the adjacent control ring 5 can also rotate.

[0058] With the cooperation of the fixing block 61 and the fixing groove 412, the fixing screw 41 also rotates with the control ring 5. At the same time, the fixing screw 41 is threadedly connected to the anti-crack strip 3. The fixing screw 41 can move away from the anti-crack strip 3 until the fixing screw 41 is inserted into the ground or into the exterior wall body.

[0059] When part of the fixing screw 41 extends out of the anti-crack strip 3, the unlocking structure 9 and the rotating structure 10 cooperate to allow the fixing block 61 to fall out of the fixing groove 412 and insert into the rotating groove 101. At this time, the control ring 5 drives the control rod 8 to rotate, and then the gear 121 drives the rack 122 to slide, and the plug rod 11 can slide away from the fixing screw 41 until the plug rod 11 is inserted into the ground or into the exterior wall. By strengthening the connection strength between the anti-crack strip 3 and the ground and the anti-crack strip 3 and the exterior wall by the plug rod 11, the number of fixing screws 41 can be appropriately reduced, achieving the effect of facilitating the installation of the anti-crack structure.

[0060] When the anti-crack strip 3 needs to be removed, the control ring 5 is rotated in the opposite direction, and the plug-in rod 11 slides toward the control rod 8. When the plug-in rod 11 is retracted into the fixed screw 41, the reset rod 141 can abut against the first connecting rod 142. At this time, with the cooperation of the first guide bevel 1421 and the second guide bevel 1441, the pushing block 144 pushes the fixed block 61 into the fixed groove 412.
