The advantages and features of the present invention will be clearer according to the following description and claims. It should be noted that the drawings are all in very simplified forms and use non-precise scales, only for the purpose of facilitating and clearly assisting in explaining the purpose of the embodiments of the present invention.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the invention, "a plurality of" means two or more unless otherwise specifically defined.

[0023] In the invention, unless otherwise clearly specified and defined, terms such as "installed", "connected", "joined", "fixed", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0024] Please refer to Figure 1 , the renovation construction protection system applied to the unilateral protection of the renovated building 1 includes: a support frame 2, including a plurality of support columns 21 and a plurality of cross beams 22 vertically fixed thereto; wherein, each cross beam 22 is assembled based on a plurality of sub-cross beams; an isolation board 3, disposed on the outer surface of the support frame 2 located on the outer side of the renovated building 1; support fittings, including a first support fitting 41 and a second support fitting, respectively used to support the floor slab 11 and the wall 12 around the intersection position of the renovated building 1 and the support frame 2.

[0025] In this embodiment, each support column 21 is an I-beam, and each sub-cross beam is an I-beam.

[0026] Furthermore, in order to increase the stability of the support frame 2, the support frame 2 further includes: a plurality of column bases, and one end of each support column 21 located below the ground is fixedly connected to a column base. Specifically, the column base is arranged below the ground as the foundation of the support column, and the pile foundation is constructed in the form of a cast-in-place pile and a steel structure foundation. Specifically, the steel structure foundation is to be inserted into the cast-in-place pile.

[0027] For the addition of a basement or the renovation and expansion of a basement that may be included in the renovation of an existing building, the support columns of the renovation construction protection system also need to pass through the basement foundation pit. Because during the excavation of the foundation pit, the support columns need to ensure stability and require appropriate strengthening. Preferably, for the column bases located indoors of the renovated building 1, the low-clearance pile foundation construction method is used for construction. In addition, the column bases of the support frame can utilize the renovated foundation structure, or new foundation structures can be added, and even the retaining piles required for adding a basement can be used as the foundation.

[0028] Please refer to Figure 4, the first support fitting 41 includes: an annular member 411 that can be sleeved outside the support column and at least three hydraulic struts 412 perpendicular to the bottom of the annular member 411. Among them, the annular member 411 is a square ring or a circular ring. In this embodiment, as Figure 4 shown, the first support fitting 41 includes a square ring and four hydraulic struts.

[0029] Please refer to Figures 5 to 9 , the second support fitting 42 includes: two first angle steels 421, two second angle steels 422, two first tie rods 423, and two second tie rods 424; among them, the two first angle steels 421 are symmetrically distributed, and a first tie rod 423 penetrates through the first flanges of the two first angle steels 421 to achieve tension support in the horizontal direction; the two second angle steels 422 are symmetrically distributed, and a first tie rod 423 penetrates through the first flanges of the two second angle steels 422 to achieve tension support in the horizontal direction; the two first angle steels 421 and the two second angle steels 422 are parallelly distributed in the vertical direction, and each second tie rod penetrates through the second flange of a first angle steel 421 located above and the second flange of a second angle steel 422 located below to achieve tension support in the vertical direction.

[0030] In this embodiment, as Figure 6 shown, the length of the first angle steel 421 is longer than that of the second angle steel 422 (that is, the first angle steel 421 located above is longer than the second angle steel 422). In this embodiment, the isolation board is preferably a perforated aluminum plate.

[0031] Correspondingly, this embodiment also provides a construction method for the reconstruction construction protection system. The following refers to Figures 1 to 11 to detail the construction method of the reconstruction construction protection system described in this embodiment.

[0032] First, perform step S1. Based on the site environment of the reconstructed building 1 and the structure of the reconstruction construction protection system, determine and mark the column positions of the reconstruction construction protection system and the positions where the cross beams pass through the wall 12 of the reconstructed building 1; among them, the column positions are distributed inside and outside the reconstructed building 1.

[0033] Specifically, according to the structural design plan of the renovation construction protection system, ensure that the position of the renovation construction protection system has no impact on the lane and building construction. Accurately position the column positions of the renovation construction protection system, and set column bases 23 below the column positions. The column bases 23 are set below the ground as the foundation for supporting columns. The pile foundations are constructed in the form of cast-in-place piles and steel structure foundations, where the steel structure foundation is inserted into the cast-in-place piles. For the addition of basements or the renovation and expansion of basements that may be included in the renovation of existing buildings, the supporting columns of the renovation construction protection system also need to pass through the basement foundation pits. During the excavation of the foundation pits, the supporting columns need to ensure stability and require appropriate reinforcement. Preferably, for the column bases 23 located indoors in the renovated building, the low-clearance pile foundation construction method is used for construction.

[0034] Next, please refer to Figure 3 and Figure 4 and execute step S2. Demolish the roof of the renovated building 1, and set a first support fitting 41 below each floor slab 11 corresponding to the marked column position on the inner side of the renovated building.

[0035] Specifically, starting from the first floor of the renovated building, mark the positions where holes need to be drilled in each floor slab 11 of the building (i.e., the marked column positions). Subsequently, the holes drilled in each floor slab 11 for the subsequent supporting column bases 23 are connected and fixed to the column bases 23 that are located below the ground as the foundation for the supporting columns, so as to improve the stability of the support frame and further improve the stability of the structure of the renovation construction protection system. Here, in order to reduce the impact on the stability of the existing renovated building during the process of drilling holes in the floor slabs, a first support fitting 41 is set below each floor slab corresponding to the marked column position on the inner side of the renovated building. In other words, while avoiding the hole-drilling position, the first support fitting 41 supports the surrounding floor slabs of the proposed hole-drilling part, so that the support structure provides sufficient reaction force for the floor slabs and breaks and drills holes in the floor slabs at the marked positions.

[0036] Next, please refer to Figure 3 and execute step S3. According to the positions of the marked column positions on each floor, break and drill holes in the floor slabs from top to bottom until the hole-drilling of each floor slab is completed.

[0037] Next, please refer to Figures 5 to 8 and execute step S4. Install a second support fitting at each position where the marked crossbeam passes through the wall 12 of the renovated building 1, and set steel supports at least on part of the second support fittings located inside the wall 12.

[0038] Specifically, according to the design plan of the renovation construction protection system, determine the position of the crossbeam connecting the supporting columns of the renovation construction protection system, determine the position of the wall of the building through which the crossbeam needs to pass, and perform hole-breaking and reinforcement treatment on the position of the wall that needs to be passed through. The specific method is as follows: 1) Mark the exterior wall through which the crossbeam needs to pass.

[0039] Install a second support structure at the marked position, such as Figure 4 and Figure 5 shown. The second support structure includes 4 angle steels. The angle steels are set at the marked position. The lengths of the two angle steels above the marked position are longer than those of the two angle steels below the marked position. The two angle steels (the first angle steels) above the marked position are respectively located on the inner and outer sides of the wall, and the two angle steels (the second angle steels) below the marked position are respectively located on the inner and outer sides of the wall. According to the positions of the holes reserved on the angle steels for passing through the first pair of tie rods (that is, holes adapted to the first pair of tie rods are reserved on the first flange of the first angle steel), drill holes in the exterior wall or the internal load-bearing wall of the building, and fasten and connect the angle steels on the inner and outer sides of the wall with the first pair of tie rods.

[0040] 2) For the angle steels on the same side of the wall, install one second pair of tie rods on each of the left and right sides of the marked position to connect them and form a reaction force between the upper and lower angle steels.

[0041] 3) After the installation of the four angle steels is completed, for the wall, at least 2 steel supports are set only under each angle steel located on the inner side of the wall. The steel supports under the angle steels (the second angle steels) below the marked position are closer to the wall, and the steel supports under the angle steels (the first angle steels) above the marked position are farther from the wall. The lower part of the steel support is supported by the floor to complete the underpinning, and no steel support is set on the outer side of the wall (as Figure 8 shown); for the internal load-bearing wall, it is possible to consider setting steel supports on both sides of the wall (as Figure 9 shown).

[0042] Next, please refer to Figure 7 , and execute step S5. According to the positions where the wall marking beams pass through on each floor, break and open holes in the wall from bottom to top.

[0043] Next, please refer to Figure 2 and Figure 3 , and execute step S6. Lift a part of the support columns among several support columns into the rebuilt building through the roof of the rebuilt building, and install them at the predetermined positions in the rebuilt building (that is, the positions of the marked column positions on each floor in S3. Each support column passes through the holes on each floor from top to bottom until it reaches and is fixedly connected to the column foundation below the ground); transport the remaining support columns to the outside of the rebuilt building and install them at the predetermined positions outside the rebuilt building.

[0044] Next, please refer to Figure 2 and Figure 3, perform step S7, hoist part of the sub-beams into the renovated building through the roof of the renovated building, and assemble them to form several beams. Each beam passes through the holes at the corresponding positions on the wall and is installed and fixed to the support columns at the corresponding positions inside and outside the renovated building; transport the remaining sub-beams to the outside of the renovated building and install and fix them to the support columns at the corresponding positions outside the renovated building.

[0045] Specifically, for hoisting and installing to form support columns and beams, for the indoor part, a hoisting device with sufficient height is required. The support columns are vertically lowered through the floor openings and installed at the designed positions. Similarly, the beams are installed in a segmented transportation method. The sub-beams are transported into the building and installed. The sub-beams are connected and assembled. First, the sub-beams are temporarily bolted together, and then welded to be fixed and assembled into a beam.

[0046] Next, please refer to Figure 1 、 Figure 2 , perform step S8, set the isolation board 3 on the outer surface of the support frame outside the renovated building. Thus, the structure of the unilateral renovation construction protection system is formed. Specifically, please refer to Figure 10 , performing step S9 specifically includes: installing purlins 5 between the crossbeams on each floor of the outdoor part of the support frame; installing the isolation board 3 on the purlins 5.

[0047] The construction method of the renovation construction protection system of the present invention realizes the purpose of setting up a unilateral steel renovation construction protection system in a narrow construction site by strengthening and making holes inside the existing building, and forming beams by directly hoisting the support columns and assembling several sub-beams. Under the condition of protecting the stability of the existing building, the setting of the renovation construction protection system on one side of the building can be completed according to requirements. When subsequent building construction is carried out, the renovation construction protection system can ensure that it will not affect the surrounding residents and businesses, and can be used as a measure for construction noise reduction and dust reduction.
