Description

Technical Field

[0001] The utility model relates to the technical field of assembled elevator shafts, in particular to an assembled elevator shaft for a newly built building. Background Art

[0002] At present, under the policy of the Ministry of Construction to improve the level of building assembly, the assembly rate requirements for new buildings are constantly increasing. In a certain base project, the main body is a steel frame structure, and the secondary structure adopts an autoclaved aerated concrete strip partition system. There is an elevator shaft in the main body, and the elevator is installed in the elevator shaft.

[0003] At present, the main forms of elevator shafts are reinforced concrete shear wall structures or aerated concrete block partition wall structures. The above construction methods have long construction intervals for secondary structure masonry construction, and the verticality of the masonry walls and the depth of the elevator shaft are prone to deviations. The construction is difficult, labor-intensive and time-consuming, and there is a serious waste of blocks and concrete materials.

[0004] The existing Chinese invention patent application with application number CN202310296154.9 discloses a prefabricated and assembled elevator shaft, which belongs to the field of installing elevators, including a bottom section, an intermediate section, a top section, and a connecting mechanism that fixes the bottom section, the intermediate section, and the top section. The steel frame structure includes four vertical and rectangular I-shaped columns, and the connecting mechanism includes: a connecting frame, which is sleeved on the outer side of the upper and lower I-shaped columns and fixed by screws, and an upper limit plate and a lower limit plate corresponding to and matching the concave surfaces of the upper and lower I-shaped columns are arranged at the middle position of the front and rear inner sides thereof; a resistance block is connected to the inside of the left and right sides of the connecting frame through a preloaded spring. The present invention cooperates with the arc-shaped portion at the top of the I-shaped groove structure, and can slide into the I-shaped groove along the arc-shaped portion through the gravity of the intermediate section and the top section itself, which is easy to assemble. At the same time, the resistance block is connected by a preloaded spring, which is convenient for the staff to make left and right fine adjustments.

[0005] The above-mentioned elevator shaft is suitable for installing elevators outside buildings that originally did not have elevators. For the new buildings of this project, since the top plate of the main structure has been constructed, the shaft assembly and hoisting cannot be realized. How to realize the assembly and installation of the new buildings is the current problem faced. Utility Model Content

[0007] The technical problem to be solved is: since the top plate of the main structure has been constructed, the hoisting and assembly of the shaft cannot be realized.

[0008] To solve the above technical problems, the present utility model adopts the following technical solutions:

[0009] A prefabricated elevator shaft for a new building of the present utility model includes a main steel structure, frame columns, spaced beams, steel frame door columns, and steel lintel beams.

[0012] The steel lintel beams are arranged between the frame columns on the entrance side of the shaft structure. The steel frame door columns are fixedly arranged in pairs between the steel lintel beams and the frame beams, and an elevator door opening is formed between each pair of steel frame door columns.

[0013] Partition walls made of strip plates are filled between the spaced beams, between the spaced beam and the frame beam, between the steel frame door columns and the frame columns, and between the steel lintel beams and the frame beams.

[0014] Angle steels are fixedly arranged on the spaced beams, frame beams, steel frame door columns, frame columns, and steel lintel beams. The partition walls made of strip plates are attached to the angle steels and fixed to the angle steels through hook bolts. The hooks of the hook bolts are hooked on the angle steels, and the other ends pass through the partition walls made of strip plates and are locked with nuts.

[0015] For a prefabricated elevator shaft for a new building of the present utility model, further, bench-type welded embedded parts are fixedly arranged on the spaced beams on the left and right sides of the entrance side of the shaft structure. The centers of the bench-type welded embedded parts on each side are located on the same vertical axis, and the inner sides of the bench-type welded embedded parts facing the inside of the shaft structure are located in the same vertical plane.

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] In this application, by using the steel columns and floor beams in the main steel structure as part of the elevator shaft structure, and cooperating with frame columns, spacer beams, steel frame door columns and steel lintel beams, a prefabricated elevator shaft for a newly-built building is formed. Compared with the traditional reinforced concrete shear wall structure or aerated concrete block masonry partition wall structure, the workload of the cast-in-place concrete structure is reduced, the input and use of materials such as formwork and wooden squares are reduced, the waste of cast-in-place concrete materials is avoided, the carbon emissions at the construction site are reduced, and the effect of green construction is achieved; compared with the prefabricated elevator shaft, its bulk components cooperate with the structural steel columns to form the elevator shaft, solving the problem that the shaft assembly hoisting cannot be realized due to the construction of the main structure roof of the newly-built building, and this application is more conducive to ensuring the construction quality of the shaft structure.
