The embodiments are only used to explain the present invention and are not intended to limit the scope of the present invention. Figure 1-4 , the preferred embodiments of the utility model are further described in detail:

[0024] like Figure 1-2 As shown, the utility model preferably adopts a protective construction system for renovation of the facade of an existing building with households, including a scaffold 3 and a protective fence 1 which are sequentially erected from the inside to the outside on the outer side of the facade of the existing building to be renovated, wherein the scaffold 3 is a double-row, ground-standing, open frame, the scaffold 3 in the non-operating area is tied and fixed to the main structure 8 by a structural wall connecting member 6, and the scaffold 3 in the merchant operating area is tied and fixed to the grille curtain wall 7 on the outer side of the main structure 8 by a curtain wall connecting member 5, the protective fence 1 is erected on the outer side of the scaffold 3 to separate the construction area from the outside, and to separate the non-operating area from the merchant operating area, and a safety passage 2 connecting the outside and the merchant shops is also provided along the facade renovation area;

[0025] Usually, the decorative curtain wall of a large shopping mall will protrude outward for a distance. At this time, the first floor of the main structure 8 will be an overall concave structure. On this basis, combined with the original intention of not affecting the normal operation of the merchants, in order to ensure the stability of the ground-type scaffolding 3, the setting of its wall connecting parts meets the requirements of the specification, such as Figure 3 As shown, the bottom of the scaffolding 3 is tied and fixed to the ground through a ground wall connecting member 4 arranged in the open space between the safety passages 2. The ground wall connecting member 4 includes a ground anchor rod 401, a transverse tie rod 402 and a diagonal brace 403. The ground anchor rod 401 is vertically anchored in the open space between the safety passages 2. The transverse tie rod 402 is horizontally arranged, with one end of its rod body fixed to the ground anchor rod 401 and the other end of its rod body fixed to the vertical pole 301 of the scaffolding 3. The diagonal brace 403 is tiltedly arranged, with the bottom end of its rod body fixed to the ground anchor rod 401 and the top end of its rod body fixed to the vertical pole 301 of the scaffolding 3.

[0026] Since the merchants in the renovation area need to operate normally, the wall connecting parts in this area cannot be erected according to the conventional design form. On this basis, in order to ensure the stability of the scaffolding 3 within this range, Figure 3As shown, the scaffolding 3 in this area is fixed to the grille curtain wall 7 by means of curtain wall connecting pieces 5, the curtain wall connecting pieces 5 include a through rod 501 and a wall connecting rod 502, the through rod 501 horizontally penetrates the grille curtain wall 7 and is welded and fixed to the transverse curtain wall keel of the grille curtain wall 7, the wall connecting rod 502 is arranged horizontally, one end of the rod body is fixed to the through rod 501, and the other end of the rod body is fixed to the vertical pole 301 of the scaffolding 3, as the transformation proceeds, the outer decorative layer of the grille curtain wall 7 and part of the keel will be removed, at this time, the safe distance between the scaffolding 3 and the structure will become larger, in order to ensure the safety of construction, it is necessary to add a filling rod 10 to the wall connecting rod 502 in this area, and ensure that the gap between the filling rod 10 and the main structure 8 on the side close to the main structure 8, the gap between the filling rod 10 and the filling rod 10, and the gap between the filling rod 10 and the scaffolding 3 on the side close to the scaffolding 3 are all less than 150mm;

[0027] In the normal construction area where no business is operating, the scaffolding 3 is tied and fixed to the main structure 8 in the form of a standard layer, such as Figure 4 As shown, the structural wall connecting member 6 includes a through-plate upright 601 and a horizontal tie rod 602. The through-plate upright 601 vertically penetrates the structural floor of the main structure 8. The horizontal tie rod 602 is arranged in pairs. The two horizontal tie rods 602 arranged in pairs are correspondingly arranged at the upper and lower positions of the structural floor. The horizontal tie rod 602 is arranged horizontally, and one end of the rod body is fixed on the through-plate upright 601, and the other end of the rod body is fixed on the upright 301 of the scaffolding 3. Of course, whether to add a filling rod 10 between the scaffolding 3 and the main structure 8 in this area can be determined according to needs. When the filling rod 10 is added, it needs to be fixed on the horizontal tie rod 602, and ensure that the gap between the filling rod 10 and the main structure 8 on the side close to the main structure 8, the gap between the filling rod 10 and the filling rod 10, and the gap between the filling rod 10 and the scaffolding 3 on the side close to the scaffolding 3 are all less than 150mm.

[0028] Taking a specific construction project as an example, the specific construction process of the utility model is introduced below:

[0029] Step 1: Compare and select renovation plans, conduct a feasibility study on the in-depth design of the demolition and renovation plan with households, design a comprehensive demolition and renovation plan for the facades of the property unit area and the non-property unit area, and do not demolish the enclosure structure in other property unit areas. Use vertical aluminum plate molding on the outside of the curtain wall keel of the original grille curtain wall 7;

[0030] Step 2: Set up protective fence 1 and safety passage 2. Set up protective fence 1 to effectively separate the construction area from the business operation area, set up safety passage 2 along the facade renovation area, and set up safety passage 2 and head protection shed at the main entrance of the operating business to ensure the normal passage of pedestrians. Strong noise and light pollution operations are carried out in different time periods and sections to avoid affecting the operation of businesses;

[0031] Step 3: Scaffold 3 is set up. Scaffold 3 is a floor-standing double-row open scaffold 3, with a height of 39.9m. The step distance between the large crossbars 302 is 1.8m, the vertical distance between the vertical poles 301 is 1.5m, the horizontal distance between the inner and outer rows of vertical poles 301 is 1.0m, the distance between the inner row of vertical poles 301 and the decoration demolition surface layer is ≤0.3m, the outer side is a steel enclosure 305, and a zigzag support 304 is added at the opening of the scaffold 3;

[0032] Step 4: The wall connection in the household construction area needs to be set up. The facade renovation needs to set up double-row ground-to-ceiling and open scaffolding 3. The objective conditions for setting up are complicated, mainly manifested in the difficulty of setting up the wall connection parts, and the design needs to be carried out according to the actual situation on site;

[0033] 1. The ground wall connection member 4 of the first floor is set. Because the first floor of the main structure 8 is an overall concave area and the merchants are in normal business, vertical ground anchor poles 401 are set in the open space between the safety passages 2 according to the on-site conditions, and connected to the frame body poles 301 through transverse pull rods 402. The poles can be connected by fasteners or other methods that meet the requirements of the specifications. If the ground anchor pole 401 is set opposite to the pole 301, a longer steel pipe can be directly selected as the small cross bar 303 of the scaffolding 3, and the end of the small cross bar 303 can be extended to The ground anchor rod 401 is directly connected to the ground anchor rod 401 and used as a transverse tie rod 402. On this basis, an additional oblique brace 403 is required to be connected and fixed to the rod 301 at the height of the first large cross bar 302 of the frame to ensure that the height of the wall connection does not exceed the safety setting requirements of the scaffold 3. At the same time, in order to ensure the safety of the frame, the two rods 301 at the wall connection position are connected to form a zigzag brace 304 with a small oblique rod to ensure the safety of the frame. Of course, in order to avoid the risk of falling from a height, an oblique steel plate 9 needs to be added to the bottom of the grille curtain wall 7 as protection;

[0034] 2. Setting of the wall connecting parts on the first floor. Because the construction area of ​​the relocated merchants only removes the ceramic panels at the original curtain wall modeling position, without destroying the overall curtain wall system, in order to ensure the normal operation of the merchants, the merchant area on the first floor uses the original external curtain wall modeling keel system, and uses the scaffolding tube as the through-rod 501 to cross the modeling keel and weld and fix it with the horizontal keel of the curtain wall keel as the tie rod of the wall tie rod 502. The wall tie rod 502 is connected and fixed to the frame body upright 301 to ensure the stability of the frame. Of course, if the position of the wall tie rod 502 coincides with the small cross bar 303, the small cross bar 303 can also be extended to be used as the wall tie rod 502 and directly fixed to the through-rod 501;

[0035] 3. In the normal construction area where no business is operating, the scaffolding 3 is tied and fixed to the main structure 8 in the form of a standard layer, such as Figure 4As shown, the structural wall connecting member 6 includes a through-plate vertical rod 601 and a horizontal tie rod 602. The through-plate vertical rod 601 vertically penetrates the structural floor of the main structure 8. The horizontal tie rod 602 is arranged in pairs. The two horizontal tie rods 602 arranged in pairs are correspondingly arranged at the upper and lower positions of the structural floor. The horizontal tie rod 602 is arranged horizontally, and one end of the rod body is fixed to the through-plate vertical rod 601, and the other end of the rod body is fixed to the vertical rod 301 of the scaffold 3.

[0036] Step 5: Setting of the filling rod 10. After the curtain wall is removed, the distance between the frame and the structure and structural members will be greater than 300mm, which may cause safety hazards. To ensure construction safety, when the distance between the frame and the structure and structural members is greater than 300mm, a horizontal large crossbar 302 is set up between the wall connecting parts (depending on the increase in the distance, ensuring that the distance between the large crossbars 302 is less than 150mm), ensuring that the distance between the large crossbars 302 and between the large crossbars 302 and the structure is less than 150mm, commonly known as the filling rod 10;

[0037] Step 6: The curtain wall is dismantled and removed with the households, and the demolition and reconstruction work is carried out in the relocated commercial area. The construction waste is transported to the indoor demolition and reconstruction area on the same floor according to the designated route. After entering the room, it is transported to the designated location by vertical transportation equipment for the construction waste stacking and removal work;

[0038] Step seven: Curtain wall installation with households. The area for relocated businesses is mainly frame glass curtain walls, metal curtain walls, and artificial board (imitation ceramic panels) curtain walls. The installation is carried out using a truck crane and the lifting operation is carried out during the business’ non-business hours.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
