[0027] The relevant technologies of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] like Figures 1 to 6 As shown, the load-bearing structure of the "industrial building roof reserved equipment" in this embodiment includes: column head support 1, embedded part 2, square steel column 3, and steel beam 4; the column head support 1 is located at the top of the load-bearing structural column 6 of the roof 5, and the column head support 1 extends vertically upward to the structural elevation of the roof 5.

[0029] An anchor bar 7 is pre-embedded in the column head support 1. A flat embedded part 2 is horizontally attached to the top surface of the column head support 1. The bottom surface of the embedded part 2 is welded to the top of the anchor bar 7. The anchor bar 7 is used to ensure that the embedded part 2 and the column head support 1 are solidified into one, so that when the square steel column 3 is subsequently installed and connected, there is sufficient lateral strength between the square steel column 3 and the column head support 1.

[0030] The bottom surface of the square steel column 3 is welded with a horizontally extending column base plate 8. The load-bearing area of ​​the column base plate 8 is larger than the bottom surface area of ​​the square steel column 3. The top surface of the embedded part 2 is connected to the bottom surface of the column base plate 8. The bottom surface of the column base plate 8 is fitted and connected with the top surface of the embedded part 2 to ensure that the vertical load can be transferred from top to bottom. The column base plate 8 is used to ensure that there is sufficient longitudinal strength between the square steel column 3 and the column head support 1.

[0031] The upper side of the square steel column 3 is longitudinally and transversely welded with a horizontally arranged steel beam 4, and the top of the steel beam 4 supports a floor 9; the large weight load generated by the industrial upper floor equipment is conducted from the floor 9 to the steel beam 4, and then from the steel beam 4 to the square steel column 3, and finally to the building bearing column through the column head buttress 1, thereby avoiding the roof 5 from bearing the large weight load generated by the industrial upper floor equipment, so that no additional equipment load allowance needs to be reserved during the design and construction of the building roof, thereby reducing the construction cost of the building roof and avoiding waste; and after the specific load generated by the industrial upper floor equipment is determined, different models and sizes of the square steel column 3, the steel beam 4 and the floor 9 can be selected according to different loads, so as to meet the load demand and also be flexibly matched according to the actual situation to meet greater load demand.

[0032] Further, the height of the column head buttress 1 upwardly protruding from the structure elevation of the roof 5 is not less than 300 mm; the reserved height space facilitates subsequent building waterproof coiled material edge structure processing.

[0033] Further, the connecting mode of the top surface of the embedded part 2 connecting the bottom surface of the column foot bottom plate 8 includes bolt connection and welding; different connecting modes can be selected according to the site condition and the demand of the industrial upper floor equipment; the welding connection mode is more firm, and the bolt connection mode has better applicability and adjustability.

[0034] Further, when the connecting mode of the top surface of the embedded part 2 connecting the bottom surface of the column foot bottom plate 8 is welding, the top surface area of the embedded part 2 is greater than the bottom surface area of the column foot bottom plate 8, and the welding seam is located at the peripheral joint between the top surface of the embedded part 2 and the column foot bottom plate 8.

[0035] Further, when the connecting mode of the top surface of the embedded part 2 connecting the bottom surface of the column foot bottom plate 8 is bolt connection, the top surface of the embedded part 2 is provided with an upwardly protruding stud, the bottom surface of the column foot bottom plate 8 is provided with a through hole corresponding to the position of the stud, and when the bottom surface of the column foot bottom plate 8 is seated on the top surface of the embedded part 2, a fastening nut is threadedly connected to one end of the stud protruding out of the through hole.

[0036] Further, when the connecting mode of the top surface of the embedded part 2 connecting the bottom surface of the column foot bottom plate 8 is bolt connection, a chemical anchor bolt is used for connection, and the chemical anchor bolt is directly implanted at the top of the column head buttress 1, so that the embedded part is not needed to be arranged, and the anchor bar is also not needed.

[0037] Further, the floor 9 includes a concrete pouring floor, a prefabricated lapping floor and a steel plate, and the selection of the floor can be different according to the site condition and the demand of the industrial upper floor equipment; the concrete pouring floor has a longer construction period but a lower cost, and the steel plate floor has a higher cost but a shorter construction period and a higher efficiency.

[0038] Further, when the floor 9 is a concrete pouring floor, the top of the steel beam 4 is welded with a stud 10, which is embedded in the poured concrete.

[0039] Further, when the floor 9 is a steel plate, the top of the steel beam 4 is welded with the bottom surface of the floor 9.

[0040] Further, the number and distribution of the longitudinal reinforcement and the stirrup in the column head buttress 1 are the same as those in the load-bearing structure column 6.

[0043] The position and the cross section of the steel beam 4 for supporting the equipment can be determined according to the specific equipment load calculation. The floor 9 can be arranged on the upper part of the steel beam 4 according to the needs, and the floor 9 can adopt the reinforced truss floor support plate, which can avoid the formwork problem caused by the pouring of the floor concrete.
