Technical Field

[0001] The utility model relates to the technical field of decoration, renovation and reconstruction construction, and in particular to a temporary corridor structure in an indoor atrium. Background Art

[0002] In the renovation of indoor atriums in large shopping malls, two or even multiple floors are often connected. Normal construction work is required on the second floor and above, and shops on the first floor need to operate normally. Therefore, it is necessary to ensure the smooth and safe flow of customers in the mall during the renovation work to meet the owner's requirements for operation. The conventional atrium renovation plan is to set up a full-floor floor-standing scaffolding, using the scaffolding as an operating platform for decoration work. However, the floor-standing scaffolding has densely arranged uprights, which is inconvenient for customers to pass through and is not beautiful. Since customers do not know much about construction and are more concerned about safety, the corresponding construction plan for the full-floor floor-standing scaffolding will reduce customer experience and even affect the total passenger flow, which will have an adverse impact on the normal business of the owner.

Please note that in order to clearly show the structure of various components of the embodiments of the utility model, the drawings are not drawn according to the same scale. The same reference numerals are used to represent the same parts.

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. 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:

[0022] like Figure 1-2 As shown, the utility model preferably adopts a temporary corridor structure of an indoor atrium, including several rows of columns 1 erected in the indoor atrium area, the columns 1 are fixedly arranged on the structural bottom plate 6 and avoid the store door position, the tops of two adjacent columns 1 are provided with main beams 2, and the tops of the main beams 2 are provided with secondary beams 3, the secondary beams 3 are arranged according to the spacing of the uprights of the scaffolding 10, and the uprights of the scaffolding 10 distributed in the corridor area are fixedly arranged on the secondary beams 3; the top of the corridor ceiling is completely closed by hard protection, and the bottom of the corridor ceiling is closed by a ceiling decoration layer arranged below the main beams 2, and lighting fixtures are installed in the ceiling decoration layer;

[0023] Among them, the location of the corridor can be determined according to the size and shape of the atrium in different areas. For a smaller atrium, the corridor can be built in a fully enclosed manner, and columns 1 are arranged at intervals throughout the atrium to fully enclose the entire atrium. The corridor ceiling is used as a platform for the scaffolding 10, and the space under the ceiling is used as a passenger flow space. For a larger atrium, a temporary corridor can be built around the edge of the atrium. The scaffolding 10 in the central area of ​​the atrium is built on the ground, and the scaffolding 10 in the corridor range is built on the ceiling. At this time, in order to ensure the safety of passage and for aesthetic considerations, the corresponding columns on the facade of the corridor close to the center of the atrium need to be closed by hard protection and corresponding decorative treatment is performed. The ceiling of the corridor away from the center of the atrium and the second-floor structural floor slab also need to be closed by hard protection;

[0024] The corridor construction plan needs to be designed in depth according to the specific conditions of the atrium and the specific requirements of the passenger flow. In order to ensure that the corridor has sufficient bearing capacity and safety, steel components should be used for the corridor components. The specifications and cross-sectional dimensions of the steel components should be designed for different atrium positions. Under the premise of ensuring safety, the principle of using less steel is adopted. Column 1 avoids the store entrance and the spacing is optimized. Since a full-floor scaffolding needs to be set up on the upper part of the corridor, welding connections are used between steel components to improve the connection strength between components. Specifically, the connection parts between column 1 and main beam 2, and between main beam 2 and secondary beam 3 are all fully penetrated secondary welds. Specifically, the corridor should be designed as a steel frame structure with a beam top height of 3m, which ensures that the passenger flow has sufficient space for activities and tries to save steel. Column 1 uses square tube □250mm×250mm×8mm, such as Figure 3 As shown, the column foot of the column 1 is considered to be hinged, and after being welded with a 500mm×500mm×20mm steel plate, it is directly placed on the ground position of the structural bottom plate 6 and anchored by expansion bolts 7. In order to avoid causing large-scale damage to the structural bottom plate 6, a layer of silicone plate can be added under the steel plate, that is, the support plate 5 at the bottom end of the column 1 is composed of an upper steel plate and a lower silicone plate. Of course, in order to improve the integrity of the column 1 and the support plate 5, a stiffening plate 8 can be welded and fixed between the middle of each side elevation of the column 1 and the upper steel plate of the support plate 5. The main beam 2 used as the frame beam adopts H-shaped steel, and the frame with a larger outer circle span The cross section of the beam is H400×200×8×13mm, and the cross section of the frame beam with a smaller span between the two circles is H300×200×8×12mm. In order to improve the stability of the main beam 2, when the height meets the requirements, the main beam 2 can also be tied and fixed with the atrium ring beam through tie measures. The top of the main beam 2 is set with a secondary beam 3 as the supporting beam of the scaffolding 10 according to the erection direction and spacing of the scaffolding 10 uprights. The secondary beam 3 adopts 16, and the spacing is distributed at 1.5m. The maximum cantilever is considered to be 1.2m, ensuring that each scaffolding 10 upright in the corridor area can be erected on the secondary beam 3 with the secondary beam 3 as the supporting rod. Figure 4As shown, the steel pipes of the vertical poles of the full-floor scaffolding 10 fall on the secondary beam 3, and the secondary beam 3 is welded with 100mm high φ25 steel bars at the corresponding vertical pole positions as limit bars 9 to prevent the vertical pole steel pipes from slipping;

[0025] In order to ensure the personal safety of customers in the corridor area and to improve the customer experience as much as possible, and to avoid safety concerns caused by the exposure of the scaffolding 10, the construction area needs to be isolated from the traffic area. For this purpose, two hard protections are set above the corridor ceiling. The first hard protection on the top of the secondary beam 3 is fully covered with 50mm thick scaffolding boards, and the upper part of the scaffolding boards is fully covered with 15mm thick film-coated multilayer boards to block the small gaps at the joints of the scaffolding boards. The second hard protection is set above the first hard protection. The second hard protection must be at least 600mm away from the first hard protection. The second hard protection is supported by steel pipes alone. The upper part of the steel pipe support is fully covered with 50mm thick scaffolding boards. The laying direction of the scaffolding boards at the second hard protection is perpendicular to the laying direction of the scaffolding boards at the first hard protection.

[0026] In general, the end of the secondary beam 3 will extend beyond the edge of the main beam 2 to form a cantilevered section. This cantilevered section also needs to be fully covered with scaffolding boards. Since the spacing of the secondary beams 2 is relatively sparse, in order to ensure the stability of the scaffolding boards, this area needs to be encrypted. The encrypted section uses a square tube □50mm×50mm×4mm as the cantilevered encrypted beam 4. The specific length of the cantilevered encrypted beam 4 is determined according to the specific setting position;

[0027] The lower part of the corridor ceiling is decorated and enclosed with white aluminum gusset plate ceiling, and the lighting is gusset plate lamp (50 watts 4000k). The side is sealed with gypsum board to prevent the construction scaffolding from being exposed, and the column 1 is decorated with a topcoat board to ensure the appearance;

[0028] The lower traffic area of ​​the corridor is equipped with fire extinguishers at the standard of 2 fire extinguishers per 100 square meters, and the location of the fire extinguishers should be set so as not to affect passenger flow.

[0029] The utility model adopts steel structure columns and beams as the main load-bearing components of the corridor to build a passage that meets the traffic requirements of the corresponding atrium passenger flow line, so as to meet the owner's ultimate goal for store operation, thereby realizing the owner's economic benefits; at the same time, the construction of the ceiling above the second floor is inserted in advance in terms of construction period, which also plays a key role in ensuring the construction period.

[0030] 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.
