Description

Technical Field

[0001] This utility model specifically relates to a support device for filling cracks in balcony railings, belonging to the field of building maintenance technology. Background Technology

[0002] With the development of the construction industry, many existing buildings are experiencing aging problems such as wall cracks due to their age. Exposed balconies, as an important part of buildings, especially cantilevered balconies, often develop horizontal cracks at the corners formed by the balcony railings and the walls, and these cracks are mostly angled downwards. These cracks not only affect the aesthetics of the building but can also lead to leaks, reduced wall structural strength, and ultimately, a continued impact on the building's lifespan and safety.

[0003] Currently, repair methods for this type of crack mainly include surface sealing, pressure grouting, and filling with flexible materials. Among these, filling with flexible materials is widely used because it can adapt to the slight deformation of the crack and is relatively easy to apply. However, in actual construction, since the crack is oriented diagonally downwards, the flexible material used for filling is prone to shifting or falling off under gravity, resulting in incomplete filling and significantly reduced repair effectiveness. Furthermore, the flexible material may also shift during the curing process due to its own weight or external disturbances, further affecting the repair quality.

[0004] To address the aforementioned issues, there is an urgent need for a device that can effectively support the flexible filling material and prevent it from shifting or falling off, thereby ensuring the compactness of the crack filling and the durability of the repair effect. Therefore, developing a crack repair device with a reasonable structure, simple construction, and the ability to effectively fix flexible materials has become a pressing technical challenge in the field of building maintenance. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, a support device for filling cracks in balcony railings is provided to solve the above problems.

[0006] A support device for filling cracks in a balcony railing includes a strip grid and multiple anchors, wherein multiple anchors are sequentially threaded through the strip grid along its length. The strip grid has multiple connecting rings along its length, and each connecting ring contains an anchor. Each anchor includes an anchor tube, a grid adjustment strip, an adjustment element, and an anchor control. The anchor control is threaded through the anchor tube and connected to the anchor tube by threads. The grid adjustment strip is threaded through the anchor control and abuts against the grid. The adjustment element is threaded through the anchor control and abuts against the grid adjustment strip. The anchor control is threaded through the connecting ring corresponding to its position.

[0007] As a preferred embodiment: the anchoring pipe includes an anchoring pipe body, multiple sector-shaped parts and multiple triangular parts. The port of the anchoring pipe is machined with internal threads. The anchoring pipe is machined with multiple strip-shaped through holes along its circumference. A sector-shaped part is hinged in each strip-shaped through hole. A triangular part is provided at the end of each sector-shaped part. When the anchoring control is not in contact with the sector-shaped part, each triangular part is in a state of retracting into the strip-shaped through hole. When the anchoring control is in contact with the sector-shaped part, each triangular part is in a state of extending out of the strip-shaped through hole.

[0008] As a preferred embodiment: the grid adjustment strip includes a ring-shaped component, two extension strips, two limiting slides, and multiple locking feet. A limiting slide is provided at the upper and lower ends of the inner wall of the ring-shaped component, and an extension strip is provided on each side of the ring-shaped component. Multiple locking feet are provided on one side of each extension strip along its length edge, and each locking foot is attached to the right angle of the corresponding strip grid hole.

[0009] As a preferred embodiment: an adjusting component is attached to one side of the annular component. The adjusting component includes a circular pusher, two side ears, two locking springs, and an L-shaped lever. The circular pusher is attached to one side of the annular component. A side ear is provided on each side of the circular pusher. A strip groove is machined at the upper and lower ends of the inner wall of the circular pusher. An elliptical through hole is machined at the upper and lower ends of the outer wall of the circular pusher. The strip groove and the elliptical through hole are connected. A locking spring is provided in each strip groove. The end of each L-shaped lever passes through the elliptical through hole corresponding to its position. The end of the L-shaped lever is set on the locking spring. The adjusting component engages with the anchoring control.

[0010] As a preferred embodiment: the annular component and the circular pusher are sequentially mounted on the anchoring control. The anchoring control includes a cylindrical component, a toothed rack, and an external thread. The annular component and the circular pusher are sequentially mounted on the cylindrical component. One end of the cylindrical component has an external thread on its outer wall, which is threadedly connected to the internal thread. The other end of the cylindrical component has a cross groove. The upper and lower ends of the outer wall of the cylindrical component are respectively machined with long grooves. A limiting slide is slidably mounted in each long groove. A toothed rack is mounted in each long groove. Each toothed rack engages with a locking spring. The cylindrical component has multiple pairs of breakage grooves along its thickness direction. Each pair of breakage grooves is located on both sides of the long groove.

[0011] The beneficial effects of this utility model are as follows: This utility model, through the cooperation of anchoring pipes, grid adjustment strips, adjustment components, and anchoring controls, firmly fixes the strip grid in the crack area, forming a stable support structure and preventing the filling material from shifting or falling off due to gravity. The adjustment components push the grid adjustment strips to squeeze the strip grid, causing the strip grid to be concave and tightly attached to the filling material, ensuring that the crack is filled densely and avoiding cavities. This utility model forms a standardized repair method for cracks in balcony railings.

[0012] When this invention is used to repair cracks with a relatively small span, it can be operated using a single strip grid. When this invention is used to repair complex cracks with high curvature and multiple locations with different directions, multiple strip grids can be arranged at various locations along the crack's direction to provide support, thus enabling it to handle repair work for different types of cracks.

Detailed Implementation

[0015] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0016] Specific implementation method one: Combining Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 This embodiment describes a balcony railing crack filling material support device, which includes a strip grid 1 and multiple anchors 2. The strip grid 1 is provided with multiple anchors 2 sequentially along its length. The strip grid 1 has multiple connecting rings 1-1 along its length, and each connecting ring 1-1 has an anchor 2. Each anchor 2 includes an anchor tube 21, a grid adjustment strip 22, an adjustment element 23, and an anchor control 24. The anchor control 24 is threaded through the anchor tube 21 and connected to the anchor tube 21. The grid adjustment strip 22 is threaded through the anchor control 24 and abuts against the strip grid 1. The adjustment element 23 is threaded through the anchor control 24 and abuts against the grid adjustment strip 22. The anchor control 24 is threaded through the connecting ring 1-1 corresponding to its position.

[0017] Multiple anchoring tubes 21 are inserted one by one into the crack 4 formed by the balcony railing 3, and anchoring control 24 is inserted into the anchoring tubes 21 to fix the anchoring tubes 21 in the crack 4. After filling the crack 4 with flexible material, multiple connecting rings 1-1 on the strip grid 1 are respectively threaded onto the corresponding anchoring control 24. The upper and lower sides of the strip grid 1 are in contact with the two walls of the balcony railing 3. Then, the grid adjustment strip 22 and the anchoring control 24 are sequentially threaded onto the anchoring control 24. When the grid adjustment strip 22 is against the strip grid 1, the anchoring control 24 continues to push the grid adjustment strip 22 to squeeze the strip grid 1, so that the middle position of the strip grid 1 is concave towards the crack 4 until the strip grid 1 contacts the filled flexible material, thereby achieving the effect of supporting the flexible material from below the strip grid 1.

[0018] Specific Implementation Method Two: This implementation method is a further limitation of Specific Implementation Method One. The anchoring pipe 21 includes an anchoring pipe body 21-1, multiple fan-shaped parts 21-2, and multiple triangular parts 21-3. The port of the anchoring pipe 21 is machined with internal threads 21-11. The anchoring pipe 21 is machined with multiple strip-shaped through holes 21-12 along its circumference. Each strip-shaped through hole 21-12 is hinged with a fan-shaped part 21-2. Each end of each fan-shaped part 21-2 is provided with a triangular part 21-3. When the anchoring control 24 is not close to the fan-shaped part 21-2, each triangular part 21-3 is in a state of being retracted into the strip-shaped through hole 21-12. When the anchoring control 24 is close to the fan-shaped part 21-2, each triangular part 21-3 is in a state of being extended out of the strip-shaped through hole 21-12.

[0019] After the anchor tube body 21-1 is inserted into the crack 4, the anchor control 24 squeezes multiple fan-shaped pieces 21-2, causing the triangular pieces 21-3 on the fan-shaped pieces 21-2 to insert into the surface of the crack 4, thereby fixing the anchor tube 21 into the crack 4.

[0020] Specific Implementation Method 3: This implementation method is a further limitation of Specific Implementation Method 1 or 2. The grid adjustment strip 22 includes an annular member 22-1, two extension strips 22-2, two limiting slides 22-4, and multiple locking feet 22-3. A limiting slide 22-4 is respectively provided at the upper and lower ends of the inner wall of the annular member 22-1. An extension strip 22-2 is respectively provided on both sides of the annular member 22-1. Multiple locking feet 22-3 are provided along the length edge of one side of each extension strip 22-2. Each locking foot 22-3 is respectively attached to the right angle of the mesh of the strip grid 1 corresponding to its position.

[0021] Multiple locking feet 22-3 can limit the position of the grid adjustment strip 22 on the strip grid 1, so that the grid adjustment strip 22 can compress the strip grid 1 along the center line of the strip grid 1. The length of the strip grid 1 depends on the specific design requirements, and 15~25cm is appropriate.

[0022] Specific Implementation Method Four: This implementation method further defines Specific Implementation Methods One, Two, or Three. An adjusting component 23 is attached to one side of the annular component 22-1. The adjusting component 23 includes a circular pusher 23-1, two side ears 23-2, two locking springs 23-3, and an L-shaped lever 23-4. The circular pusher 23-1 is attached to one side of the annular component 22-1. A side ear 23-2 is provided on each side of the circular pusher 23-1. A strip-shaped... The groove 23-12 and the outer wall of the annular pusher 23-1 each have an elliptical through hole 23-11 machined at their upper and lower ends. The strip groove 23-12 is connected to the elliptical through hole 23-11. Each strip groove 23-12 is provided with a locking spring 23-3. The end of each L-shaped lever 23-4 passes through the elliptical through hole 23-11 corresponding to its position. The end of the L-shaped lever 23-4 is set on the locking spring 23-3. The adjusting member 23 engages with the anchoring control 24.

[0023] When it is necessary to disassemble the adjustment component 23, pull the two L-shaped levers 23-4 outwards respectively, so that the operating locking spring 23-3 of the L-shaped levers 23-4 disengages from the anchoring control 24, thereby realizing the quick disassembly and assembly of the adjustment component 23 on the anchoring control 24.

[0024] Specific Implementation Method Five: This implementation method further defines Specific Implementation Methods One, Two, Three, or Four. The annular member 22-1 and the circular pusher 23-1 are sequentially mounted on the anchoring control 24. The anchoring control 24 includes a cylindrical member 24-1, a toothed row 24-2, and an external thread 24-3. The annular member 22-1 and the circular pusher 23-1 are sequentially mounted on the cylindrical member 24-1. One end of the cylindrical member 24-1 has an external thread 24-3 on its outer wall, which is threadedly connected to the internal thread 21-11. The other end of the cylindrical member 24-1... One end face is machined with a cross groove 24-11. The upper and lower ends of the outer wall of the cylindrical part 24-1 are respectively machined with long strip grooves 24-12. A limiting slide 22-4 is slidably arranged in each long strip groove 24-12. A toothed row 24-2 is arranged in each long strip groove 24-12. Each toothed row 24-2 is engaged with a locking spring 23-3. The cylindrical part 24-1 is machined with multiple pairs of breakage grooves 24-13 along its thickness direction. Each pair of breakage grooves 24-13 is located on both sides of the long strip groove 24-12.

[0025] One end of the cylindrical member 24-1 is inserted into the anchoring tube 21-1. The external thread 24-3 is threadedly connected to the internal thread 21-11. As the cylindrical member 24-1 continues to advance and comes into contact with multiple fan-shaped members 21-2, the fan-shaped members 21-2 are squeezed and unfold outward, so that the triangular members 21-3 on the fan-shaped members 21-2 are inserted into the surface of the crack 4, thereby fixing the anchoring tube 21 in the crack 4 and filling the crack 4 with flexible material.

[0026] Multiple connecting rings 1-1 on the strip grid 1 are respectively threaded onto the corresponding cylindrical members 24-1. Then, the ring-shaped member 22-1 and the circular pusher 23-1 are threaded onto the cylindrical member 24-1. At this time, the limiting slide member 22-4 is slidably set in the long groove 24-12, thereby effectively restricting the position of the grid adjustment plate 22, ensuring that the extension strip 22-2 coincides with the center line of the strip grid 1. The locking spring 23-3 meshes with the toothed row 24-2, so that the circular pusher 23-1 can only move unidirectionally towards the crack 4. The circular pusher 23-1 pushes the grid adjustment plate 22 to squeeze the strip grid 1, so that the middle position of the strip grid 1 bends towards the crack 4 and contacts the filling flexible material, thereby achieving the purpose of supporting the flexible material. If the flexible material is recessed after solidification, the mesh of the strip grid 1 can be used for secondary material filling.

[0027] After the flexible material is filled, the locking spring 23-3 is disengaged from the toothed rack 24-2 by operating the L-shaped lever 23-4. At this time, the grid adjustment strip 22 and the adjustment piece 23 are removed from the column 24-1. If the column 24-1 can be removed, it can be rotated through the cross groove 24-11 to remove it from the crack 4. If the column 24-1 is partially wrapped by the flexible material and cannot be removed, the column 24-1 is bent multiple times using the corresponding break groove 24-13 according to the distance of the column 24-1 buried in the crack 4 to break it. It can then be covered by plastering and other operations to achieve a flat and beautiful surface of the balcony railing 3.

[0028] Working principle: Multiple anchoring tubes 21 are inserted one by one into the crack 4 formed by the balcony railing 3, and anchoring control 24 is inserted into the anchoring tubes 21 to fix the anchoring tubes 21 in the crack 4. After filling the crack 4 with flexible material, multiple connecting rings 1-1 on the strip grid 1 are respectively threaded onto the corresponding anchoring control 24. The upper and lower sides of the strip grid 1 are in contact with the two walls of the balcony railing 3. Then, the grid adjustment strip 22 and the anchoring control 24 are sequentially threaded onto the anchoring control 24. When the grid adjustment strip 22 is against the strip grid 1, the anchoring control 24 continues to push the grid adjustment strip 22 to squeeze the strip grid 1, so that the middle position of the strip grid 1 is concave towards the crack 4 until the strip grid 1 contacts the filling flexible material. This achieves the effect of supporting the flexible material from below the strip grid 1, preventing the flexible material from sliding down due to gravity and causing the crack 4 to have a cavity.
