[0047] The following is a detailed description of the proposed construction protection system and method for retrofitting, in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are highly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0048] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0049] In the description of the invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the invention.

[0050] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of an invention, "plurality" means two or more, unless otherwise specifically defined.

[0051] In the present invention, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be interpreted broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0052] Please refer to Figure 1 The renovation construction protection system, applied to the single-side protection of the renovated building 1, includes: a support frame 2, including a plurality of support columns 21 and a plurality of beams 22 fixed perpendicularly thereto; wherein each beam 22 is assembled based on a plurality of sub-beams; an insulation board 3, arranged on the outer surface of the support frame 2 located outside the renovated building 1; and support accessories, including a first support accessory 41 and a second support accessory, respectively used to support the floor slab 11 and wall 12 around the intersection of the renovated building 1 and the support frame 2.

[0053] In this embodiment, each support column 21 is an I-beam, and each sub-crossbeam is an I-beam.

[0054] Furthermore, to increase the stability of the support frame 2, the support frame 2 also includes a plurality of column bases. Each support column 21 is fixedly connected to a column base at one end below the ground. Specifically, the column base is provided below the ground and serves as the foundation for the support column. The pile foundation is constructed using cast-in-place piles and a steel structure foundation. Specifically, the steel structure foundation is inserted into the cast-in-place piles.

[0055] For existing building renovations that may include adding a basement or expanding a basement, the support columns of the construction protection system will need to pass through the basement foundation pit. This is because during the excavation of the foundation pit, the support columns need to be appropriately reinforced to ensure stability. Preferably, a low-headroom pile foundation construction method is used for the indoor column foundations of the renovated building 1. In addition, the column foundations of the support frame can utilize the renovated foundation structure, a new foundation structure can be added, or even the retaining piles required for the additional basement can be used as the foundation.

[0056] Please refer to Figure 4 The first supporting accessory 41 includes: an annular component 411 that can be sleeved on the outside of the supporting column and at least three hydraulic support rods 412 perpendicular to the bottom of the annular component 411. The annular component 411 is a square ring or a circular ring. In this embodiment, Figure 4 As shown, the first support fitting 41 includes a square ring and four hydraulic struts.

[0057] Please refer to Figures 5 to 9 The second supporting accessories 42 include: two first angle steels 421, two second angle steels 422, two first tensioning members 423 and two second tensioning members 424; wherein, the two first angle steels 421 are symmetrically distributed, and a first tensioning member 423 passes through the first flanges of the two first angle steels 421 to achieve horizontal tension support; the two second angle steels 422 are symmetrically distributed, and a first tensioning member 423 passes through the first flanges of the two second angle steels 422 to achieve horizontal tension support; the two first angle steels 421 and the two second angle steels 422 are distributed in parallel in the vertical direction, and each second tensioning member passes 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 vertical tension support.

[0058] In this embodiment, Figure 6 As shown, the length of the first angle steel 421 is longer than the length of the second angle steel 422 (ie, the first angle steel 421 located at the top is longer than the second angle steel 422). In this embodiment, the isolation plate is preferably a perforated aluminum plate.

[0059] Accordingly, this embodiment also provides a construction method for modifying the construction protection system. Figures 1 to 11 The construction method of the modified construction protection system described in this embodiment is described in detail.

[0060] First, execute step S1 to determine and mark the column positions and beam positions of the renovation construction protection system passing through the wall 12 of the renovation building 1 based on the site environment of the renovation building 1 and the structure of the renovation construction protection system; wherein the column positions are distributed on the inner and outer sides of the renovation building 1.

[0061] Specifically, according to the structural design plan of the renovation and construction protection system, ensure that the location of the renovation and construction protection system has no impact on the driveway and building construction, accurately locate the column position of the renovation and construction protection system, and set the column base 23 below the column position. The column base 23 is set below the ground as the foundation of the support column, and the pile foundation is constructed in the form of cast-in-place piles and steel structure foundations, where the steel structure foundation is to be inserted into the cast-in-place piles. For the addition of basements or basement expansion projects that may be included in the reconstruction of existing buildings, the support columns of the renovation and construction protection system must also pass through the basement foundation pit, because during the excavation of the foundation pit, the support columns must ensure stability and need to be appropriately reinforced. Preferably, a low-headroom pile foundation construction method is used for the column base 23 located indoors in the renovated building.

[0062] Next, please refer to Figure 3 and Figure 4 , execute step S2, remove the roof of the rebuilt building 1, and set a first supporting accessory 41 below each floor slab 11 corresponding to the position of the column marked on the inner side of the rebuilt building.

[0063] Specifically, starting from the first floor of the renovated building, the locations where holes need to be opened in the floor slabs 11 of each floor of the building (i.e., the marked column positions) are marked. Subsequently, the holes opened in each floor slab 11 by the supporting column bases 23 are connected and fixed to the column bases 23 located below the ground, which serve as the foundation of the supporting columns, so as to improve the stability of the support frame and thus improve the stability of the renovation construction protection system structure. Here, in order to reduce the impact on the stability of the existing renovated building during the process of opening holes in the floor slabs, a first support accessory 41 is set below each floor slab corresponding to the position of the marked column on the inner side of the renovated building. In other words, the first support accessory 41 avoids the hole opening position while supporting the floor slabs around the planned hole opening portion, so that the support structure provides sufficient reaction force for the floor slabs to break the floor slabs at the marked position and open the hole.

[0064] Next, please refer to Figure 3 , execute step S3, and according to the position of the marking column of each floor, break the floor slab from top to bottom to open the hole until the hole of each floor slab is completed.

[0065] Next, please refer to Figures 5 to 8 , execute step S4, install a second support accessory at each marked beam passing position on the wall 12 of the renovated building 1, and set a steel support on at least the part of the second support accessory located on the inner side of the wall 12.

[0066] Specifically, according to the design plan of the renovation construction protection system, determine the position of the supporting beams connected to the renovation construction protection system, determine the position of the wall of the building through which the beams need to pass, and make holes and reinforce the wall positions that need to be passed through. The specific steps are as follows:

[0067] 1) Mark the exterior walls where the beams need to pass through.

[0068] Set up a second support structure at the marked location, e.g. Figure 4 and Figure 5 As shown, the second support structure includes four angle steels, which are positioned at the marked locations. The two angle steels above the marked locations are longer than the two angle steels below the marked locations. The two angle steels above the marked locations (first angle steels) are located on the inner and outer sides of the wall, respectively, while the two angle steels below the marked locations (second angle steels) are located on the inner and outer sides of the wall, respectively. Based on the locations of the holes reserved in the angle steels for the first pair of tie rods (i.e., holes are reserved on the first flange of the first angle steel for the first pair of tie rods), holes are drilled into the exterior or interior load-bearing wall of the building, and the angle steels on the inner and outer sides of the wall are fastened together using the first pair of tie rods.

[0069] 2) For the angle steel on the same side of the wall, install a second pair of tie rods on the left and right sides of the marked position to connect them and form a reaction force between the upper angle steel and the lower angle steel.

[0070] 3) After the four angle steels are installed, for the wall, only set at least 2 steel supports under each angle steel located on the inside of the wall. The steel support under the angle steel below the mark (the second angle steel) is closer to the wall, and the steel support under the angle steel above the mark (the first angle steel) is farther from the wall. The floor slab is used as support under the steel support to complete the replacement. No steel support is set on the outside of the wall (such as Figure 8 As shown); For internal load-bearing walls, consider setting steel supports on both sides of the wall (as shown Figure 9 shown).

[0071] Next, please refer to Figure 7 , execute step S5, mark the position where the beam passes through the wall of each floor, and break the wall from bottom to top to open the hole.

[0072] Next, please refer to Figure 2 and Figure 3 , execute step S6, hoist some of the support columns from the roof of the rebuilt building into the rebuilt building, and install them at the predetermined positions in the rebuilt building (i.e., the positions of the column positions marked on each floor in S3, each support column passes through the holes on each floor slab from top to bottom until it reaches the ground and is connected and fixed to the column base); transport the remaining support columns to the outside of the rebuilt building, and install them at the predetermined positions outside the rebuilt building.

[0073] Next, please refer to Figure 2 and Figure 3 , execute step S7, hoist some of the sub-beams through the roof of the rebuilt building into the rebuilt building, assemble them into several beams, each beam passes through a hole at a corresponding position on the wall, and is installed and fixed to the support columns located at corresponding positions inside and outside the rebuilt building; transport the remaining sub-beams to the outside of the rebuilt building, and install and fix them to the support columns located at corresponding positions outside the rebuilt building.

[0074] Specifically, the support columns and beams are hoisted and installed. For indoor areas, sufficiently high hoisting equipment is required to lower the support columns vertically through the floor openings and install them in the designed positions. Similarly, the beams are installed in sections, with the sub-beams transported into the building and installed. Each sub-beam is connected and assembled. Multiple sub-beams are first connected and assembled with temporary bolts, and then fixed together by welding to form a single beam.

[0075] Next, please refer to Figure 1 、 Figure 2 , execute step S8, set the insulation board 3 on the outer surface of the support frame outside the renovated building. So far, the single-side renovation construction protection system structure is formed. For details, please refer to Figure 10 Executing step S9 specifically includes: installing purlins 5 between the beams of each layer of the outdoor part of the support frame; and installing insulation boards 3 on the purlins 5.

[0076] The construction method for the retrofit construction protection system of this invention achieves the goal of installing a single-sided steel retrofit construction protection system in a confined construction site by reinforcing and breaking holes within the existing building, directly hoisting support columns and assembling them with several sub-beams to form a crossbeam. While protecting the stability of the existing building, the retrofit construction protection system can be installed on a single side of the building as needed. During subsequent construction, the retrofit construction protection system ensures that it will not impact surrounding residents and businesses, serving as a construction noise and dust reduction measure.
