Description

Technical Field

[0001] This application belongs to the field of manufacturing technology of tools for the restoration of ancient houses, specifically a support frame used to support workers in the restoration of ancient houses. Background Technology

[0002] Ancient buildings and old houses, as important carriers of history and culture, carry rich humanistic information and architectural techniques. Their restoration and protection are of irreplaceable significance for inheriting historical culture and continuing the architectural lineage. In the process of restoring ancient buildings and old houses, adhering to the principle of "restoring the old as it was" and maintaining the original appearance of the old houses is a basic requirement. This is not only a respect for historical features, but also the key to protecting the integrity of cultural heritage.

[0003] However, over the years, the old house has suffered from weathering and erosion, resulting in severe decay of its wooden structure, with some areas so fragile that they could crumble at the slightest touch. This situation presents significant safety risks for workers undertaking high-altitude repairs. The difficulty in accurately assessing whether the existing structure can support human weight makes climbing to the roof or other heights extremely challenging. Traditional fixed support structures, often installed via welding, are difficult to adjust flexibly based on the internal dimensions of the house, such as beam-column spacing and roof slope, leading to low construction efficiency. Utility Model Content

[0004] The purpose of this application is to address the shortcomings of existing technologies by using three sets of support beams combined with outer rotating beams, connecting columns, support columns, and other components to form an adjustable three-dimensional support frame. This frame can be flexibly assembled according to the actual dimensions of the beam-column spacing and roof slope inside the old house, adapting to spaces of different specifications and solving the problem of poor adaptability of traditional fixed supports.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] A support frame for supporting workers during the restoration of ancient houses includes support beams in three sets. Multiple sets of rotating beams are rotatably connected to the outer sides of each of the three sets of support beams. Connecting columns are installed on the outer sides of the lower two sets of support beams. Multiple sets of support columns are inserted into the lower inner side of each connecting column and fixed in place by bolts. Tensioners are installed on the outer sides of the lower two sets of support beams. Multiple sets of support plates are also fixed to the outer sides of each support column by bolts. Adjacent sets of support plates are staggered in an X-shape. Mounting holes are provided through the outer sides of both the support plates and the support columns. Adjustment components are provided at the bottom ends of each support column.

[0007] Preferably, the tensioning member includes a snap-fit ​​member, which snaps onto the outside of the support beam. A fixing rod is fixedly connected to the outside of the snap-fit ​​member. Multiple sets of snap-fit ​​members are provided, and two adjacent sets of snap-fit ​​members are fixedly connected to the two ends of the fixing rod.

[0008] Preferably, the snap-fit ​​component is U-shaped, and a bolt and nut are provided at the U-shaped opening of the snap-fit ​​component for fastening.

[0009] Preferably, the adjusting component includes an adjusting base, which is threadedly connected to the inner wall of the support column. A fixing component is fixedly connected to the upper part of the adjusting base. A sliding groove is provided on the inner wall of the fixing component. A plug-in component is slidably connected to the inner wall of the sliding groove of the fixing component. A limit component is rotatably connected to the outer side of the plug-in component. A pull rod is fixedly connected to the outer side of the limit component.

[0010] Preferably, a positioning groove is provided on the outer side of the support column, and the outer side of the connector is inserted into the inner wall of the positioning groove.

[0011] Preferably, the positioning grooves are provided in multiple sets, and the multiple sets of positioning grooves are distributed in a circular array around the center of the support column.

[0012] Preferably, the limiting member contacts the inner wall of the groove of the fixing member, and the limiting member has a notch on the side near the insertion member.

[0013] Preferably, the pull rod is L-shaped, and a counterweight ball is provided at the lower part of the L-shaped pull rod.

[0014] This application has the following beneficial effects:

[0015] 1. This application uses three sets of support beams, along with outer rotating beams, connecting columns, and support columns, to form an adjustable three-dimensional support frame. All components are connected by bolts, allowing for flexible assembly based on the actual dimensions of the old house, such as beam-column spacing and roof slope, adapting to different space specifications. This solves the problem of poor adaptability of traditional fixed supports and improves construction efficiency.

[0016] 2. This application connects the components by bolts, plugs, etc., and can be installed without professional tools. Compared with traditional on-site welding or custom support, it greatly shortens the construction cycle. The counterweight ball of the tie rod can keep the limiting part in a horizontal state. After the height of the support column is adjusted, the support column and the adjustment base are locked under the action of gravity and friction, which improves the stability of the device.

Detailed Implementation

[0022] See Figures 1-4 A support frame for supporting workers during the restoration of old houses includes three sets of support beams 1 arranged in a triangular pattern. These beams bear the weight of the restoration workers, tool loads, and part of the old house's structural weight. The load is transferred to the support columns 4 and the ground via rotating beams 2 and connecting columns 3. Multiple rotating beams 2 are rotatably connected to the outer sides of each of the three sets of support beams 1. These rotating beams 2, in conjunction with tension members 5, fix the support beams 1 into a triangular shape, thereby improving the structural stability of the device. The angle of the support beams 1 can be adjusted by rotation to adapt to irregular beam and column orientations or roof slopes in the old house, achieving dynamic load distribution. Connecting columns 3 are located on the outer sides of the lower two sets of support beams 1 to connect the support beams 1 and the support columns 4. The lower inner diameter of the connecting columns 3 is larger than the outer diameter of the support columns 4. Multiple sets of support columns 4 are inserted into the lower inner side of the connecting column 3 and fixed by bolts. Tensioners 5 are provided on the outer side of the two sets of lower support beams 1 to fix the distance between the two sets of lower support beams 1. Multiple sets of support plates 6 are also fixed on the outer side of the support column 4 by bolts. The two sets of support plates 6 are arranged in an X shape and staggered, forming an anti-overturning support in the plane using the principle of cross mechanics, preventing the support column 4 from shifting due to unilateral force. The outer side of the support plate 6 and the support column 4 are provided with through holes. By rotating the support plate 6 at different angles, the bolts can be installed through the corresponding holes to accommodate support columns 4 with different spacing, thereby adapting to irregular spaces, solving the problem of poor adaptability of traditional fixed supports, and improving construction efficiency. Adjustment parts 7 are provided at the bottom of the support column 4.

[0023] As a preferred embodiment, the tension member 5 includes a snap-fit ​​member 51, which snaps onto the outside of the support beam 1. The snap-fit ​​member 51 is U-shaped, and bolts and nuts are provided at the U-shaped opening of the snap-fit ​​member 51 for fastening. The snap-fit ​​member 51 is a U-shaped metal part, which can be quickly assembled and disassembled by bolts and nuts. By deforming the snap-fit ​​member 51, the friction with the support beam 1 is increased to prevent slippage. A fixing rod 52 is fixedly connected to the outside of the snap-fit ​​member 51. The fixing rod 52 can form a continuous horizontal cable system. By replacing the fixing rod 52 with different lengths, it can be adapted to old house spaces of different widths. Multiple sets of snap-fit ​​members 51 are provided, and two adjacent sets of snap-fit ​​members 51 are fixedly connected to the two ends of the fixing rod 52.

[0024] As a preferred embodiment, the adjusting component 7 includes an adjusting base 71, which is threadedly connected to the inner wall of the support column 4. The adjusting base 71 can be rotated to move up and down, adjusting the total height of the support column 4 to accommodate uneven ground or settlement differences in the foundation of older buildings. A fixing component 72 is fixedly connected to the upper part of the adjusting base 71. A groove on the inner wall of the fixing component 72 allows the insert 74 to slide laterally. After being inserted into the positioning groove 73 on the outer side of the support column 4, the position of the insert 74 is locked by rotating the limiting component 75. A groove is formed on the inner wall of the fixing component 72, and the insert 74 is slidably connected to the inner wall of the groove. The limiting component 75 is rotatably connected to the outer side of the insert 74. By horizontally abutting against the inner wall of the groove, the adjusting base 71 can be positioned... The support column 4 is locked, and the limiting member 75 contacts the inner wall of the sliding groove of the fixing member 72. The limiting member 75 has a notch on the side near the plug-in member 74. A pull rod 76 is fixedly connected to the outer side of the limiting member 75, which makes it easy for the operator to rotate and pull the limiting member 75. A positioning groove 73 is opened on the outer side of the support column 4. The outer side of the plug-in member 74 is inserted into the inner wall of the positioning groove 73, which can limit the adjustment base 71 and prevent loosening. Multiple sets of positioning grooves 73 are opened, and the multiple sets of positioning grooves 73 are distributed in a circular array around the center of the support column 4. The pull rod 76 is set in an L shape, and a counterweight ball is set at the lower part of the L-shaped pull rod 76. Gravity is used to keep the limiting member 75 horizontal. After the adjustment is completed, it automatically locks to prevent loosening due to vibration.

[0025] In use, depending on the interior space of the old house, the three sets of support beams 1 are arranged in a triangle or horizontally. The rotating beam 2 makes initial contact with the beams and columns at the top of the old house. When the rotating beam 2 adapts to the roof slope (e.g., the slope angle ≤ 30°), the rotating beam 2 can be adjusted to the corresponding tilt angle. Connecting columns 3 are installed on the outside of the two sets of support beams 1 at the bottom. The support columns 4 are inserted into the inside of the connecting columns 3 and fixed with bolts to form a vertical support system.

[0026] The tension member 5 is held tightly to the outside of the support beam 1 by the U-shaped clip 51. After the bolts and nuts are tightened, the fixing rod 52 forms a horizontal cable to restrain the lateral displacement of the support beam 1. Support plates 6 are installed in layers on the outside of the support column 4, with adjacent groups staggered in an X shape and fixed by bolts through mounting holes to form an anti-overturning support network.

[0027] When it is necessary to rotate and adjust the base 71, first rotate the pull rod 76 to make the limiting member 75 vertical. Then pull the pull rod 76 to drive the plug-in member 74 to disengage from the positioning groove 73. When the notch on the limiting member 75 moves out of the inner wall of the sliding groove of the fixing member 72, it limits the limiting member 75.

[0028] The support column 4 is moved up and down by the threaded drive until the support beam 1 is tightly fitted with the roof structure of the old house (if the gap is ≤2mm as measured by visual inspection or feeler gauge). The limiter 75 is operated in the opposite direction, and with the gravity of the counterweight ball of the pull rod 76, the limiter 75 is kept horizontal (after locking the support column 4, the gap between the plug 74 and the positioning groove 73 is ≤0.5mm).

[0029] For severely decayed roof areas, the rotating beam 2 can share part of the old house's self-weight. If the purlin load is transferred to the supporting beam 1 through the rotating beam 2, the theoretical unloading ratio can be 30% to 50%, which needs to be calculated based on the actual condition of the old house.

[0030] With this design, when repairing an old house, the structure can be supported internally using this invention, allowing workers to climb onto the outer roof for repairs. Without this internal support, workers risk falling while climbing onto the roof. Especially considering the differences in shape and layout between old houses, the ability to be assembled as needed is even more essential.
