Description

Technical Field

[0001] The invention relates to the field of building reinforcement engineering, and in particular to a diagonal brace assembled high-rise wall column replacement reinforcement support device and method. Background Art

[0002] Before dismantling the original concrete components, reliable support equipment should generally be used to unload the original structure. At present, the common support form is to anchor reinforced concrete sleeves or crown beams behind the upper and lower wall columns of the construction components. The vertical force borne by the wall columns is transmitted to the corbels, and then transmitted to the lower sleeves through the vertical support (generally steel) components, and then transmitted to the lower wall columns through the sleeves to achieve the purpose of support unloading. Or set large steel beams or integral steel corbels to connect the upper and lower wall columns, and then transfer the upper load of the replacement concrete wall columns to the lower layer through vertical support to achieve the purpose of unloading.

[0003] In the above-mentioned traditional support methods, the installation of vertical supports often requires the destruction of the upper and lower floors of the construction layer in order to contact the upper and lower wall column sleeves or steel sections to achieve load transfer. In the case of high-rise wall column concrete replacement, the structural span is large, the wall column design cross-sectional dimensions are large, and the required unloading force is often huge. At this time, the required vertical supports are set more vertically. In addition, considering the large height of the vertical supports, the vertical supports are often stability-controlled cross-sections, resulting in a large single vertical support, which causes greater damage to the slab structure when passing through the floor. At the same time, the construction of the concrete sleeve requires planting of reinforcement and pouring of concrete. Construction can only be carried out after the strength reaches the designed support strength. After the construction is completed, it needs to be dismantled and cannot be reused, which inevitably leads to an extension of the construction period and waste of materials.

[0062] In this embodiment, except for the inner shaft sleeve 5, all components are assembled components, which realizes lightweight installation and reusability of replacement equipment.

[0063] Embodiment 2:

[0064] This embodiment provides an installation method of a diagonal brace assembled high-rise wall column replacement reinforcement support device, using the replacement reinforcement support device of embodiment 1, including the following steps:

[0065] First, install the upper support.

[0066] First, use a drilling machine to open two Ø76mm wall column circular holes at the appropriate height of the wall column, with a depth of about 300mm. When opening the circular holes, use a steel bar detector to avoid the wall column steel bars. Screw the inner sleeve 5 into the center shaft 8. After screwing, make the inner sleeve 5 flush with the end of the center shaft 8. Insert one end of the center shaft 8 with the inner sleeve 5 into the wall column circular hole opened in advance, so that the inner sleeve 5 is completely embedded in the wall column circular hole. At this time, the center shaft 8 is inserted into the wall column circular hole and does not fall off.

[0067] The rectangular sleeve 7 is rotated and screwed into the central shaft 8 on the side away from the rod end. When screwing in, the side of the rectangular sleeve 7 with the end plate 20 is close to the wall column until the end plate 20 of the rectangular sleeve 7 is tightly attached to the concrete surface of the wall column. At this time, the central shaft 8 is leveled along the rod axis with the assistance of a laser leveler using a temporary jack or a hanging rope, and then fixed after leveling. Use an electric hammer to drill holes through the end plate bolt holes at the position where the end plate 20 is close to the concrete of the wall column, and fix the end plate 20 with bolts to achieve the fixation of the rectangular sleeve 7 and the concrete of the wall column.

[0068] The outer sliding sleeve 10 is inserted into the outer end of the rectangular sleeve 7, and the limiting nut 9 is temporarily screwed in.

[0069] According to the same method, another set of inner sleeve 5, central shaft 8, rectangular sleeve 7, outer sliding sleeve 10 and limiting nut 9 are installed.

[0070] After installation, the pressing plate 6 is placed on the bottom and top surfaces of the two sets of rectangular sleeves 7 , and is tightened and connected through the bolt holes of the pressing plate 6 with high-strength screws to achieve the effect of tightening the pressing plate 6 to the two rectangular sleeves 7 .

[0071] At the bottom of the pressure plate 6, the first pad 4 is laid on the ground. Before installing the first pad 4, the ground must be leveled first, and the centroid position of the first pad 4 is aligned with the centroid position of the rectangular sleeve 7. The first jack 2 is installed on the first pad 4, and the pressure sensor 3 and the rectangular block 14 are installed on the top surface of the first jack 2 in sequence. At this time, the first jack 2 is slowly raised until it contacts the bottom surface of the pressure plate 6.

[0072] At about 1.5m above the circular hole in the wall column concrete, the upper end plate 13 is laid out and installed, and fixed to the wall column with chemical anchor bolts through the bolt holes on the upper end plate 13. During installation, the centroid position of the upper end plate 13 should be in the same vertical plane as the centroid positions of the two outer sleeves 10.

[0073] Screw the threaded ends of the two steel bars of the diagonal brace 11 into the bottom of the brace sleeve 12. At this time, the total length of the diagonal brace is at its shortest. Align the diagonal brace 11 and the brace sleeve 12 through the axial hole at one end of the diagonal brace 11 and the axial hole of the ear plate of the upper end plate 13, and insert a 10.9s-grade M50 screw to fix it. At this time, the total length of the diagonal brace 11 is controlled by rotating the brace sleeve 12 so that the axial hole at the other end of the diagonal brace 11 is aligned with the axial hole of the ear plate of the outer sleeve 10. After alignment, insert a 10.9s-grade M42 screw to fix it.

[0074] Install the lower support in the same way as the upper support.

[0075] Installation of intermediate support:

[0076] Install the second pad 21 at the centroid position of the first jack 2 of the upper support and the lower support. Evenly install two vertical supports 1 on the second pad 21, with a net distance of 100 mm between the vertical supports 1. Install the second jack 15, the pressure sensor 3 and the second pad 21 in sequence on the top surface of the vertical support 1. Check whether there is any gap in the installation of each support component, and check the alignment of the jack and the sensor.

[0077] After installing the support on one side of the wall column, install the support device on the other side of the wall column (if necessary) in the same way. After all the supports are installed and adjusted to the correct center, the wall column concrete replacement reinforcement support unloading work can be carried out according to the reinforcement design plan or construction design unloading amount.

[0078] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations.
