Description

Technical Field

[0001] The invention relates to the technical field of decoration construction, and in particular to a steel frame transfer layer for suspending large-area overweight soft furnishings and a construction method. Background Art

[0002] When large shopping malls are renovated and reused, they often carry out diversified designs and personalized decoration. In this type of decoration, the structure mostly uses large metal components, which have the characteristics of heavy single and combined parts, scattered component installation locations, large overall installation range, uneven load distribution, and excessive local loads. Therefore, during construction, it is necessary to solve the problem of safe bearing of the overall load when the soft decoration is hoisted as a whole, and it is necessary to solve the problem of excessive load at some points of the soft decoration.

[0003] There are two conventional construction methods. One is to increase the main and secondary beam sections of the main building, and use the increased main and secondary beams to hoist the soft decoration. This is the most conventional construction method. However, the mechanical and electrical pipelines of the building structure are all existing structures during the reuse and renovation. Line rectification or removal is not only a huge workload, but also extremely costly, and it also seriously increases the construction period. In addition, the increase in the beam section requires planting and chiseling during the construction process, which greatly disturbs the original structure. The quality of indoor renovation concrete pouring cannot be guaranteed, and there are structural safety and quality risks. The other is to set up a steel frame transfer layer to achieve the hoisting of the soft decoration. However, the existing steel frame transfer layer is directly connected to the building floor plate through a hanger, and the entire steel frame transfer layer adopts a single-layer plane setting; as a result, the existing steel frame transfer layer cannot solve the problem of excessive local load, and cannot effectively solve the problem of load transfer. In addition, the reuse and renovation make it impossible to install hangers at the location of the mechanical and electrical pipelines on the building floor plate, which further aggravates the problems of unstable hoisting and overload, making the above hoisting method have the defects of high cost or safety hazards. The present invention provides a steel frame transfer layer and a construction method for suspending large-area overweight soft furnishings to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present 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 cannot be understood as a limitation on the present invention.

[0020] like Figure 1 , 2 As shown in Figure 3, a steel frame transfer layer for suspending large-area and overweight soft furnishings comprises a steel frame layer 1 and a hanger layer 2. The steel frame layer 1 is arranged on a column and is located below the building floor slab. The hanger layer 2 is arranged directly below the steel frame layer 1, and the soft furnishings are arranged directly below the hanger layer 2.

[0021] The specific embodiments of the present invention are as follows. When the shopping mall is renovated and reused, the escalator connecting the underground first floor and the second floor and the ceiling structure above it are installed by integral hoisting. Since the deadweight of the escalator is extremely large, far exceeding the size and deadweight of the existing decoration ceiling, it is necessary to provide a stable and safe hoisting method. Since it is a renovated and reused, it is necessary to avoid modifying the electromechanical pipelines as much as possible. At the same time, since the load borne by the hoisting structure directly above the escalator is the largest, even if a hanger is set up to balance the load, there is still a problem of local load exceeding the limit. Therefore, the method of hoisting the soft decoration as a whole on the building floor slab by a hanger cannot meet the safety and stability requirements, and the method of increasing the beam cross section cannot meet the requirements due to structural safety defects. The present invention arranges a steel frame layer above the hanger layer to bear and transfer the load, and uses the columns as the installation structure of the steel frame layer to transfer the load of the overweight soft decoration to the columns step by step, thereby ensuring the stable bearing of the soft decoration structure and avoiding the safety hazards of the building floor slab caused by the load exceeding the limit.

[0022] like Figure 1 , 2As shown in Figures 3 and 4, the steel frame layer 1 includes an installation area 100 and a cantilever area 200. The installation area 100 is arranged on the columns and is located between the columns. There are a total of six columns arranged in a "日" shape. The installation area 100 is set in the column area and is used to bear the overweight load of the escalator structure below. The installation area 100 can transfer the load to the columns through the structural beams and columns. The load of the escalator structure is transferred to the secondary support beam 13 through the connecting beam 14, and then transferred to the main support beam 12 and the columns through the secondary support beam 13, realizing the layer-by-layer transfer of the load. The cantilever area 200 is cantilevered on the side of the installation area 100 and is used to bear the light load of the ceiling structure and accessory structure of the escalator. The cantilever area 200 transfers the load it bears to the installation area 100 and then to the columns. According to the different loads, zoning is adopted. The installation area 100 with a larger load is directly connected to the columns and is set within the support range of the columns to achieve stable support; the cantilever area 200 with a smaller load is set in a cantilevered manner, and the load it bears is transferred to the installation area 100 and then to the columns to meet the load-bearing requirements.

[0023] As Figure 3 shown, both the installation area 100 and the cantilever area 200 of the steel frame layer 1 include structural beams and columns and hanging seats 11. The hanging seats 11 are arranged on the bottom surfaces of the structural beams and columns, and the hanging frame layer 2 is connected to the hanging seats 11; the structural beams and columns include main support beams 12, secondary support beams 13 and connecting beams 14. The main support beams 12 are arranged between the columns. The secondary support beams 13 include inter-column secondary support beams 131 and connecting beam secondary support beams 132. The inter-column secondary support beams 131 are arranged between the columns. The inner end of the connecting beam secondary support beam 132 is connected to the main support beam 12, and the outer end is connected to the inter-column secondary support beam 131. The connecting beam 14 is connected to the secondary support beam 13 and the columns.

[0024] As Figure 2 、 3 、4 shown, the main support beam 12 of the installation area 100 is arranged at the center of the installation area 100 and serves as the central beam of the steel frame layer 1 and is also the structural beam and column that bears the largest load. It is used to connect the connecting beam secondary support beam 132 to realize load transfer. The inter-column secondary support beam 131 is arranged between two adjacent columns and includes an upper inter-column secondary support beam 1311 and a lower inter-column secondary support beam 1312. The upper inter-column secondary support beam 1311 is used to connect to the connecting beam 14 to realize load transfer. The lower inter-column secondary support beam 1312 is located below the connecting beam secondary support beam 132 and the connecting beam 14 and is used to support the two. The load of the connecting beam secondary support beam 132 and the connecting beam 14 is transferred to the lower inter-column secondary support beam 1312 and then to the columns. The cantilever area 200 is composed of connecting beams 14 and bears a lighter load. The connecting beam 14 meets the load-bearing requirements. The connecting beam 14 of the cantilever area 200 transfers the load it bears to the columns and the inter-column secondary support beam 131.

[0025] like Figure 2 , 3 As shown in Figure 4, further, the secondary support beam 131 between columns includes an upper-layer secondary support beam 1311 between columns and a lower-layer secondary support beam 1312 between columns. The outer end of the connecting beam secondary support beam 132 is connected to the lower-layer secondary support beam 1312 between columns. The upper-layer secondary support beam 1311 between columns is used to transfer the load transferred by the connecting beam 14, and the lower-layer secondary support beam 1312 between columns is used to support the connecting beam secondary support beam 132 and the connecting beam 14 in the cantilever area 200, thereby ensuring the full-length setting of the secondary support beam 13 and improving the load-bearing capacity of the structural beam and column.

[0026] like Figure 2 , 3 As shown in Figures 4, 5, 6 and 7, further, the main support beam 12, the secondary support beam 1311 between the upper columns, the connecting beam secondary support beam 132 and the connecting beam 14 are located in the same plane, and the secondary support beam 1312 between the lower columns is located below the connecting beam secondary support beam 132. The secondary support beams 1311 between the upper columns and the secondary support beams 1312 between the lower columns are arranged in layers, which ensures that the secondary support beams 13 are not interrupted and arranged throughout the length. Moreover, the layering makes the steel frame layer 1 form a multi-layer three-dimensional structure, which is more conducive to the transfer and uniform distribution of the load. At the load exceeding limit point, the load is transferred layer by layer and the load is evenly distributed through the three-dimensional structure, which improves the structural stability and safety.

[0027] like Figure 3 , 4 As shown, further, the structural beams and columns of the installation area 100 include a main support beam 12, a secondary support beam 13 and a connecting beam 14, and the structural beams and columns of the cantilever area 200 include a connecting beam 14, the connecting beam 14 of the installation area 100 is connected to the secondary support beam 13, and the connecting beam 14 of the cantilever area 200 is connected to the secondary support beam 13 and the column.

[0028] Furthermore, the hanger 11 is arranged on the secondary support beam 13 and the connecting beam 14 .

[0029] Furthermore, the main support beam 12 and the secondary support beam 13 are both arranged throughout the entire length, and the entire length arrangement ensures the load bearing capacity of the main support beam 12 and the secondary support beam 13 .

[0030] Furthermore, the hanger layer 2 includes a hanger rod and a hanger, the hanger is located directly below the steel frame layer 1, and the hanger is connected to the steel frame layer 1 through the hanger rod.

[0031] like Figure 8 As shown, further, the main support beam 12 is arranged on the column through a corbel support, so as to improve the stability of the main support beam 12 and ensure that the load can be stably transferred to the column.

[0032] Preferably, the main support beam 12 , the secondary support beam 13 and the connecting beam 14 are connected by welding, and the hanger 11 is welded to the secondary support beam 13 and the connecting beam 14 .
