Description

Technical Field

[0002] Steel shell segments usually refer to the decomposition of the entire structure into multiple parts for easy manufacturing, transportation and installation in large steel structure projects, such as bridges, high-rise buildings or marine engineering structures. Each part is called a "segment". This segmented design not only helps to simplify the construction process, but also improves project efficiency and safety. Common connection methods for steel shell segments include welding, bolting, nested connection, etc. The specific selection depends on the structural characteristics and construction conditions. During the manufacturing process of steel shell segments, if concrete filling or other situations requiring steel bars are included, special attention should be paid to the positioning of the vertical steel bars.

[0003] When inserting the steel bars, they need to be inserted along the steel bar holes opened on the surface of the vertical reinforcing ribs of the connecting part in the steel shell segment. When inserted, the steel bars will collide with the inner wall of the steel bar hole, causing the steel bars to vibrate. When inserting multiple connecting part units continuously, the steel bars need to be positioned between two adjacent connecting part units to avoid the steel bars being difficult to align with the steel bar holes on the surface of the next connecting part due to their own vibration. Therefore, the present application provides a method for accurately positioning the vertical steel bars at the connection position of the steel shell segment to meet the needs.

[0019] In the above scheme, by setting the support assembly, arranging multiple groups of support boxes, and specially designing the installation positions of the multiple groups of support boxes to be A support reference is formed on the inner wall of the connection frame, so that the connection frame can ensure the connection effect of the outer wall plate and the inner wall plate while having a secondary support effect on the outer wall plate and the inner wall plate. At the same time, the force of squeezing the arc-shaped contact block when the steel bar is inserted is used to realize the extension of the rubber support block through the sliding cooperation between the wedge block 1 and the wedge block 2. At the same time, multiple groups of The support box arranged in a letter shape realizes multi-point support effect on the outer wall panel and the inner wall panel through the extension of multiple groups of rubber support blocks, ensuring the support effect of multiple groups of rubber support blocks among the outer wall panel, the inner wall panel and the connecting frame. At the same time, by utilizing the wear resistance and corrosion resistance of nitrile rubber, the service life of the multiple groups of rubber support blocks when supporting the outer wall panel and the inner wall panel is improved, further ensuring the sustainability of the support effect of the multiple groups of rubber support blocks.

[0020] By setting a positioning component and utilizing the cooperation between the positioning base plate and the positioning box, when multiple sets of connection frames are connected up and down, the weight of the connection frame itself is utilized, and multiple sets of clamping columns are specially designed on the side of the positioning base plate, and multiple sets of slide grooves are synchronously provided on the inner wall of the positioning box to achieve a precise positioning connection effect between the positioning base plate and the positioning box. At the same time, multiple sets of trigger pressure rods are specially designed at the bottom end of the positioning base plate, and the linkage cooperation between the trigger arc plate, the rotating rod and the arc positioning plate is realized to achieve the two sets of arc positioning plates at the top position of the vertical positioning hole to be close to each other, forming a positioning ring between the multiple sets of connection frames.

When the steel bars pass through the arc positioning plate, the shock-absorbing rubber pad fits the surface of the steel bars to reduce shock on the steel bars, thereby avoiding large shaking of the steel bars themselves, which interferes with the connection effect between the outer wall plate, the inner wall plate and the connecting frame. At the same time, it avoids large shaking of the steel bars themselves, which makes it difficult to align with the vertical positioning holes, ensuring the accuracy and stability of the steel bars during vertical insertion. At the same time, multiple sets of ball bearings are arranged, and the multiple sets of ball bearings fit the surface of the steel bars and rotate when the steel bars are inserted, ensuring the smoothness of the steel bar insertion and the insertion effect of the steel bars.

[0021] By setting up a cleaning component and specially designed cleaning plates, a cleaning ring surface is formed by fitting two sets of cleaning plates together and around the steel bars. At the same time, multiple sets of scraping rings are specially designed on the inner walls of the two sets of cleaning plates. The high hardness and wear resistance of the silica material are used to scrape the rust on the surface of the passing steel bars to ensure the smoothness of the steel bar surface. At the same time, through the splicing effect between the two sets of cleaning plates and the connection effect of bolt two, during use, bolt two and the two sets of cleaning plates can be disassembled and removed, and the scraping rings on the inner walls of the cleaning plates can be maintained and cleaned for the second time to ensure the service life of the scraping rings. At the same time, by setting up multiple sets of small industrial fans and cooperating with the multiple sets of ventilation holes on the surface of the cleaning plates, the rust scraped off by the scraping rings is blown to avoid the scraped rust accumulating in the internal cavity of the cleaning plates, further ensuring the treatment effect of rust on the surface of the steel bars.

[0047] like Figures 1 to 12 As shown, the installation device includes an outer wall panel 1, a connecting frame 2 is installed on the inner wall of the outer wall panel 1, one end of the connecting frame 2 is connected to the inner wall panel 3, a plurality of groups of vertical positioning holes 4 are provided on the top surface of the connecting frame 2, a plurality of groups of horizontal positioning holes 5 are provided on both sides of the connecting frame 2, the inner walls of the plurality of groups of vertical positioning holes 4 are in contact with steel bars 6, a support assembly 7 is installed on the inner wall of the connecting frame 2, the support assembly 7 is used to provide auxiliary support between the outer wall panel 1 and the inner wall panel 3, a positioning assembly 8 is installed on the top of the connecting frame 2, the positioning assembly 8 is used to assist in positioning the vertically inserted steel bars 6 between the upper and lower groups of connecting frames 2, a cleaning assembly 9 is installed on one side of the support assembly 7, the cleaning assembly 9 is used to clean rust on the surface of the steel bars 6, the positioning assembly 8 is located at the top of the support assembly 7, and the cleaning assembly 9 is located on one side of the support assembly 7.

[0048] By setting the support assembly 7, the installation positions of the multiple support boxes 71 are specially designed to be A support reference is formed on the inner wall of the connecting frame 2, so that the connecting frame 2 has a secondary support effect on the outer wall panel 1 and the inner wall panel 3 while ensuring the connection effect of the outer wall panel 1 and the inner wall panel 3. By setting the positioning component 8, the shock-absorbing rubber pad 89 is fitted to the surface of the steel bar 6 to perform shock-absorbing treatment on the steel bar 6 to avoid the large shaking of the steel bar 6 itself from interfering with the connection effect between the outer wall panel 1, the inner wall panel 3 and the connecting frame 2. By setting the cleaning component 9, the rust on the surface of the steel bar 6 is scraped to ensure the smoothness of the surface of the steel bar 6.

[0049] like Figures 4 and 5 As shown, the support assembly 7 includes a support box 71, and the number of the support boxes 71 is set to multiple groups, and the multiple groups of support boxes 71 are arranged in a The zigzag structure is installed on the inner wall of the connecting frame 2, and a through hole 72 is provided on the top surface of the support box 71. An arc-shaped contact block 73 is nested and installed on the inner wall of the through hole 72. The number of arc-shaped contact blocks 73 is set to two groups, and the two groups of arc-shaped contact blocks 73 are symmetrically arranged on the inner wall of the through hole 72. A spring 1 74 is installed on one side of the surface of the extended part of one end of the arc-shaped contact block 73. The spring 1 74 is elastically connected to the inner wall of the support box 71. A wedge 1 75 is installed on the extended part of one end of the arc-shaped contact block 73. One side of the surface of the wedge 1 75 contacts the wedge 2 76. One end of the wedge 2 76 is connected to a rubber support block 77. The rubber support block 77 is installed on the inner wall of one side of the support box 71. A spring 2 78 is installed on one side of the surface of the connecting part of the rubber support block 77 and the wedge 2 76. One end of the spring 2 78 is elastically installed on the inner wall of the support box 71. The rubber material in the rubber support block 77 is set to nitrile rubber.

[0050] Then, when the operator inserts the steel bar 6 vertically through the vertical positioning hole 4 at the top of the connecting frame 2, the steel bar 6 approaches and passes through the through hole 72 at the top of the support box 71. When the steel bar 6 continues to pass through the through hole 72, it contacts and pushes the surface of the arc contact block 73. Under the action of the continuous passage of the steel bar 6, the arc contact block 73 slides. While the arc contact block 73 slides, it drives the spring 1 74 to extend. While the arc contact block 73 slides, it drives the wedge 1 75 to slide synchronously. While the wedge 1 75 slides, it contacts and pushes the wedge 2 76, so that the wedge 2 76 is nested in the inner wall of the support box 71 and slides. While the wedge 2 76 slides, it drives the spring 2 78 to extend. At the same time, the wedge 2 76 drives the rubber support block 77 to slide synchronously, so that the rubber support block 77 extends from one side of the surface of the support box 71.

[0051] Rubber support blocks 77 are synchronously extended from the surfaces of multiple groups of support boxes 71, so that rubber support blocks 77 are extended from both sides of the connecting frame 2. When the multiple groups of rubber support blocks 77 are extended, they respectively contact the surfaces of the outer wall panel 1 and the inner wall panel 3. At the same time, through the connecting action of the connecting frame 2, auxiliary support is provided to the outer wall panel 1 and the inner wall panel 3 respectively.

[0052] By arranging multiple groups of support boxes 71, the installation positions of the multiple groups of support boxes 71 are specially designed to be A support reference is formed on the inner wall of the connection frame 2 so that the connection frame 2 has a secondary support effect on the outer wall panel 1 and the inner wall panel 3 while ensuring the connection effect on the outer wall panel 1 and the inner wall panel 3.

[0053] like Figures 6 to 9As shown, the positioning assembly 8 includes a positioning base plate 81, the number of the positioning base plates 81 is set to two groups, the two groups of positioning base plates 81 are installed at the bottom end of the connecting frame 2, the bottom surface of the positioning base plate 81 is arranged with multiple groups of trigger pressure rods 82 in an array, and multiple groups of card columns 83 are installed on both sides of the positioning base plate 81. The positioning assembly 8 also includes a positioning box 84, the number of the positioning box 84 is set to two groups, the two groups of positioning boxes 84 are installed at the top of the connecting frame 2, the inner wall of the positioning box 84 is provided with multiple groups of slide grooves 85, and the multiple groups of slide grooves 85 are connected to the multiple groups of The clamping columns 83 correspond one to one, and a trigger arc plate 86 is nested and installed on the inner wall of the positioning box 84. The surface of the trigger arc plate 86 contacts the bottom surface of the trigger pressure rod 82. One end of the trigger arc plate 86 is connected to a rotating rod 87, and the rotating rod 87 is installed on the inner wall of the positioning box 84. The other end of the rotating rod 87 is connected to an arc-shaped positioning plate 88, and the arc-shaped positioning plate 88 is nested and installed on the inner wall of the positioning box 84. A plurality of groups of shock-absorbing rubber pads 89 are arranged in an array on the surface of the arc-shaped positioning plate 88, and a plurality of groups of balls 810 are installed in an equiangular circular array on the surface of the arc-shaped positioning plate 88.

[0054] When the operator connects multiple connecting frames 2 in sequence, when one group of connecting frames 2 at the upper position is placed on the top of another group of connecting frames 2 at the lower position, one group of connecting frames 2 at the upper position drives the positioning base plate 81 at the bottom end to approach the positioning box 84 at the top end of the other group of connecting frames 2 at the lower position, and aligns the multiple groups of clamping columns 83 on the side of the positioning base plate 81 with the multiple groups of sliding grooves 85 on the side of the positioning box 84. Under the action of the weight and gravity of the connecting frames 2 themselves, the positioning base plate 81 drives the clamping columns 83 to slide along the inner wall of the sliding groove 85, so that the positioning base plate 81 approaches and fits the bottom end of the inner wall of the positioning box 84.

[0055] As the positioning base plate 81 slides, it drives the multiple groups of trigger pressure rods 82 at the bottom end to approach and contact the trigger arc plate 86. Under the sliding action of the positioning base plate 81, the trigger pressure rods 82 push the trigger arc plate 86 to slide to one side. As the trigger arc plate 86 slides, it pushes one end of the rotating rod 87, causing the rotating rod 87 to rotate. As the rotating rod 87 rotates, the other end pushes the arc-shaped positioning plate 88 to slide nested on the inner wall of the positioning box 84, so that the two groups of arc-shaped positioning plates 88 at the top position of the vertical positioning hole 4 approach each other, and a positioning ring is formed at the top position of the vertical positioning hole 4 by the two groups of arc-shaped positioning plates 88 approaching each other.

[0056] After the multiple connection frames 2 are connected in sequence, the operator uses a welding gun or other processing equipment to weld the multiple connection frames 2. Subsequently, the splicing units of the outer wall panel 1 and the splicing units of the inner wall panel 3 are welded to both sides of the connection frame 2 respectively.

[0057] When the steel bar 6 is close to the two groups of arc-shaped positioning plates 88, the two groups of arc-shaped positioning plates 88 at the top position of the vertical positioning holes 4 are used to assist in positioning between the two adjacent connecting frames 2, and to assist in guiding the steel bar 6 passing through the two adjacent connecting frames 2. At the same time, multiple groups of balls 810 on the inner wall of the arc-shaped positioning plates 88 assist in the insertion of the steel bar 6. The rotation effect of the multiple groups of balls 810 is used to improve the smoothness of the steel bar 6 when it is inserted and passes through the arc-shaped positioning plates 88. At the same time, the shock-absorbing rubber pads 89 are used to perform shock-absorbing treatment on the steel bar 6 to reduce the vibration generated when the steel bar 6 is inserted.

[0058] By setting up the cooperation between the positioning base plate 81 and the positioning box 84, when multiple groups of connecting frames 2 are connected up and down, the weight of the connecting frame 2 itself is utilized, and multiple groups of clamping columns 83 are specially designed on the side of the positioning base plate 81, and multiple groups of sliding grooves 85 are synchronously set on the inner wall of the positioning box 84, so as to achieve a precise positioning connection effect between the positioning base plate 81 and the positioning box 84.

[0059] like Figures 10 to 12 As shown, the cleaning component 9 includes a mounting frame 91, which is mounted on one side of one group of support boxes 71 by bolt 1 92, and the inner wall of the mounting frame 91 is connected to a cleaning plate 94 by bolt 2 93, and the number of cleaning plates 94 is set to two groups, and the two groups of cleaning plates 94 are in contact with each other, and a vent 95 is installed through the surface of the cleaning plate 94, and multiple groups of scraping edge rings 96 are installed on the inner wall of the cleaning plate 94, and the cross-section of the scraping edge ring 96 is designed to be a semicircular structure, and the material of the scraping edge ring 96 is set to be, a small industrial fan 97 is installed on one side of the mounting frame 91, and the number of small industrial fans 97 is set to multiple groups, and the multiple groups of small industrial fans 97 are arranged in a horizontal array on the surface of one side of the mounting frame 91.

[0060] At the same time, when the steel bar 6 is inserted, the steel bar 6 passes through the circular cavity formed by the two sets of cleaning plates 94. When the steel bar 6 passes through, the surface of the steel bar 6 and the multiple sets of scraping ridges 96 on the inner wall of the two sets of cleaning plates 94 are scraped by the multiple sets of scraping ridges 96 using the high hardness of silicon dioxide to scrape the surface of the steel bar 6, thereby scraping away the rust on the surface of the steel bar 6;

[0061] During this process, the operator starts the multiple sets of small industrial fans 97 on one side of the mounting frame 91. After the multiple sets of small industrial fans 97 are started, they blow out airflow. Under the continuous blowing action of the small industrial fans 97, the blown airflow enters the internal cavity of the cleaning plate 94 through the vents 95 on the surface of the cleaning plate 94. The rust scraped off by the multiple sets of scraping rings 96 is removed by the continuous inflow of airflow.

[0062] At the same time, when the insertion of the steel bar 6 is completed, the operator can use a tool to unscrew bolt 1 92 to disconnect the mounting frame 91 from one set of support boxes 71, and remove the mounting frame 91 as a whole. Then the operator can use a tool to unscrew bolt 2 93 again to disconnect the two sets of cleaning plates 94 from the mounting frame 91, and perform a secondary cleaning on the surface of the multiple sets of scraping edge rings 96 on the inner wall of the cleaning plate 94.

[0063] Through specially designed cleaning plates 94, two sets of cleaning plates 94 are attached to each other and form a cleaning ring surface around the steel bar 6. At the same time, multiple sets of scraping edge rings 96 are specially designed on the inner walls of the two sets of cleaning plates 94 to scrape the rust on the surface of the steel bar 6 passing through.

[0064] The working principle of the technical solution provided by the present invention is as follows:

[0065] When the operator connects multiple connecting frames 2 in sequence, when one group of connecting frames 2 at the upper position is placed on the top of another group of connecting frames 2 at the lower position, one group of connecting frames 2 at the upper position drives the positioning base plate 81 at the bottom end to approach the positioning box 84 at the top end of the other group of connecting frames 2 at the lower position, and aligns the multiple groups of clamping columns 83 on the side of the positioning base plate 81 with the multiple groups of sliding grooves 85 on the side of the positioning box 84. Under the action of the weight and gravity of the connecting frames 2 themselves, the positioning base plate 81 drives the clamping columns 83 to slide along the inner wall of the sliding groove 85, so that the positioning base plate 81 approaches and fits the bottom end of the inner wall of the positioning box 84.

[0066] As the positioning base plate 81 slides, it drives the multiple groups of trigger pressure rods 82 at the bottom end to approach and contact the trigger arc plate 86. Under the sliding action of the positioning base plate 81, the trigger pressure rods 82 push the trigger arc plate 86 to slide to one side. As the trigger arc plate 86 slides, it pushes one end of the rotating rod 87, causing the rotating rod 87 to rotate. As the rotating rod 87 rotates, the other end pushes the arc-shaped positioning plate 88 to slide nested on the inner wall of the positioning box 84, so that the two groups of arc-shaped positioning plates 88 at the top position of the vertical positioning hole 4 approach each other, and a positioning ring is formed at the top position of the vertical positioning hole 4 by the two groups of arc-shaped positioning plates 88 approaching each other.

[0067] After the multiple connection frames 2 are connected in sequence, the operator uses a welding gun or other processing equipment to weld the multiple connection frames 2. Subsequently, the splicing units of the outer wall panel 1 and the splicing units of the inner wall panel 3 are welded to both sides of the connection frame 2 respectively.

[0068] Then, when the operator inserts the steel bar 6 vertically through the vertical positioning hole 4 at the top of the connecting frame 2, the steel bar 6 approaches and passes through the through hole 72 at the top of the support box 71. When the steel bar 6 continues to pass through the through hole 72, it contacts and pushes the surface of the arc contact block 73. Under the action of the continuous passage of the steel bar 6, the arc contact block 73 slides. While the arc contact block 73 slides, it drives the spring 1 74 to extend. While the arc contact block 73 slides, it drives the wedge 1 75 to slide synchronously. While the wedge 1 75 slides, it contacts and pushes the wedge 2 76, so that the wedge 2 76 is nested in the inner wall of the support box 71 and slides. While the wedge 2 76 slides, it drives the spring 2 78 to extend. At the same time, the wedge 2 76 drives the rubber support block 77 to slide synchronously, so that the rubber support block 77 extends from one side of the surface of the support box 71.

[0069] The rubber support blocks 77 are extended synchronously from the surfaces of the multiple groups of support boxes 71, so that the rubber support blocks 77 are extended from both sides of the connecting frame 2. The multiple groups of rubber support blocks 77 are extended and contact the surfaces of the outer wall panel 1 and the inner wall panel 3 respectively. At the same time, the outer wall panel 1 and the inner wall panel 3 are provided with auxiliary support respectively through the connection function of the connecting frame 2.

[0070] When the steel bar 6 approaches the two sets of arc-shaped positioning plates 88, the two sets of arc-shaped positioning plates 88 at the top of the vertical positioning holes 4 are used to assist in positioning between the two adjacent connection frames 2, and the steel bar 6 passing through the two adjacent connection frames 2 is assisted in guiding. At the same time, the multiple sets of balls 810 on the inner walls of the arc-shaped positioning plates 88 assist in inserting the steel bar 6. The rotation effect of the multiple sets of balls 810 is used to improve the smoothness of the steel bar 6 when inserting and passing through the arc-shaped positioning plates 88. At the same time, the shock-absorbing rubber pads 89 are used to perform shock-absorbing treatment on the steel bar 6 to reduce the vibration generated when the steel bar 6 is inserted.

[0071] At the same time, when the steel bar 6 is inserted, the steel bar 6 passes through the circular cavity formed by the two sets of cleaning plates 94. When the steel bar 6 passes through, the surface of the steel bar 6 and the multiple sets of scraping ridges 96 on the inner wall of the two sets of cleaning plates 94 are scraped by the multiple sets of scraping ridges 96 using the high hardness of silicon dioxide to scrape the surface of the steel bar 6, thereby scraping away the rust on the surface of the steel bar 6;

[0072] During this process, the operator starts the multiple sets of small industrial fans 97 on one side of the mounting frame 91. After the multiple sets of small industrial fans 97 are started, they blow out airflow. Under the continuous blowing action of the small industrial fans 97, the blown airflow enters the internal cavity of the cleaning plate 94 through the vents 95 on the surface of the cleaning plate 94. The rust scraped off by the multiple sets of scraping rings 96 is removed by the continuous inflow of airflow.

[0073] At the same time, when the insertion of the steel bar 6 is completed, the operator can use a tool to unscrew bolt 1 92 to disconnect the mounting frame 91 from one set of support boxes 71, and remove the mounting frame 91 as a whole. Then the operator can use a tool to unscrew bolt 2 93 again to disconnect the two sets of cleaning plates 94 from the mounting frame 91, and perform a secondary cleaning on the surface of the multiple sets of scraping edge rings 96 on the inner wall of the cleaning plate 94.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention.
