Description
Technical Field
[0001] The utility model relates to the field of elevator installation, in particular to a steel structure light well support frame. Background Art
[0002] Traditional elevator hoistways mainly have two structural forms: concrete and steel structure. Concrete elevator hoistways generally reserve space in advance at the beginning of new building construction, which is not only costly but also affects the layout of the building. When installing elevators on old buildings, steel structure welded hoistways are mostly used. However, the existing steel structure hoistways are generally heavy, requiring on-site welding and hoisting by workers, which not only has great construction difficulty but also a long construction period. Due to the generally narrow roads in old residential areas, it will cause inconvenience to the travel of community residents during construction. Content of the Utility Model
[0003] The purpose of the utility model is to overcome the deficiencies existing in the prior art, and provide a steel structure light well support frame, which makes the installation convenient and greatly shortens the construction time through mortise and tenon splicing and welding processes. The modular well steel frame is not restricted by the installation environment, and can be installed even in narrow passages.
[0004] The purpose of the utility model is completed by the following technical solutions: This steel structure light well support frame includes columns, I-beam crossbeams and strengthening columns. The columns are arranged vertically at the four corners of the elevator hoistway. The columns include lower columns arranged at the lower part of the well support frame and upper columns arranged at the upper part of the well support frame. Bottom connection grooves are opened at the bottoms of each lower column and upper column, middle connection grooves are opened in the middle, and top connection grooves are opened at the tops;
[0005] The I-beam crossbeams include a first connection crossbeam, a second connection crossbeam and an intermediate connection crossbeam. The top connection grooves of the lower columns are aligned with the bottom connection grooves of the upper columns, and are connected by mortise and tenon joints through the first connection crossbeam and the second connection crossbeam, so that adjacent lower columns and upper columns are connected and supported by the first connection crossbeam or the second connection crossbeam; The intermediate connection grooves located in the middle of adjacent lower columns and adjacent upper columns are connected by mortise and tenon joints with the intermediate connection crossbeam; The top connection grooves of each upper column are connected and supported by the first connection crossbeam or the second connection crossbeam;
[0006] The strengthening columns are connected between adjacent first connection crossbeams and intermediate connection crossbeams, and between adjacent second connection crossbeams and intermediate connection crossbeams.
[0007] As a further technical solution, two fixing holes are penetrated and opened in the middle of each I-beam cross beam, and the two fixing holes are distributed vertically; connecting grooves are opened at both ends of the reinforcing column, and connecting holes are penetrated and opened at positions corresponding to the connecting grooves on the surface of the reinforcing column. The reinforcing column is inserted into the middle of the corresponding I-beam cross beam through the connecting groove, so that the connecting hole is aligned and fixed with one fixing hole.
[0008] As a further technical solution, one reinforcing column is arranged above and below the same I-beam cross beam, so that the two fixing holes of the same I-beam cross beam are fixedly connected with one connecting hole, and the end faces of the two reinforcing columns are in contact with each other for support.
[0009] As a further technical solution, the middle rib plate of the middle connecting cross beam extends to both sides to form a flange for inserting into the middle connecting groove, and the height of the flange is half of the height of the middle connecting cross beam.
[0010] As a further technical solution, a set of notches are symmetrically opened on the upper and lower surfaces on both sides of the first connecting cross beam, and each set of notches is separated by the middle rib plate of the first connecting cross beam for inserting into the bottom connecting groove and / or the top connecting groove; two sets of notches are symmetrically opened on the upper and lower surfaces on both sides of the second connecting cross beam, and there is a gap between the two sets of notches. Each set of notches is separated by the middle rib plate of the second connecting cross beam for inserting into the bottom connecting groove and / or the top connecting groove.
[0011] As a further technical solution, the lower column and the upper column are both square tubes, and the bottom connecting groove, the middle connecting groove, and the top connecting groove are opened on three corresponding side surfaces of each lower column and upper column. Two first connecting cross beams and two second connecting cross beams are inserted crosswise between the top connecting grooves of the four upper columns. Three middle connecting cross beams are inserted between the middle connecting grooves of the four lower columns. Three middle connecting cross beams are also inserted between the middle connecting grooves of the four upper columns. Two first connecting cross beams and one second connecting cross beam are distributed crosswise at the connection between the lower column and the upper column, so that there is no I-beam cross beam in one side space of the shaft support frame, which is used as the connecting and communicating side with the building.
[0012] As a further technical solution, the depth of the bottom connecting groove of the upper column is equal to the depth of the bottom connecting groove and the top connecting groove of the lower column, and both are half of the height of the first connecting cross beam and the second connecting cross beam; the depth of the top connecting groove of the upper column is equal to the height of the first connecting cross beam and the second connecting cross beam, so that after the first connecting cross beam and the second connecting cross beam are inserted into the top connecting groove of the upper column, the upper surface is flush with the upper column.
[0013] As a further technical solution, during docking, a set of notches of the first connecting cross beam are correspondingly inserted into a top connecting groove of the column, two sets of notches of the second connecting cross beam are correspondingly inserted into the remaining two top connecting grooves of the same column, and the parts of the second connecting cross beam located outside the two end notches are exposed from the side surface of the column.
[0014] As a further technical solution, the mortise and tenon connection positions of the hoistway support frame are all connected by full welding.
[0015] The beneficial effects of the present utility model are as follows:
[0016] 1. The steel structures are connected by mortise and tenon joints, making the installation operation during construction more convenient and fast, improving the construction efficiency. I-beam cross beams are arranged at the butt joints of the columns and in the middle of the columns for support. At the same time, strengthening columns are connected between the I-beam cross beams and fixed with bolts to enhance the overall strength of the elevator shaft frame.
[0017] 2. Based on the mortise and tenon connection, full welding is carried out to strengthen the connection reliability of the elevator shaft frame, forming a double safety guarantee, and it is applicable to the internal space of buildings and narrow space environments where construction vehicles cannot enter.
[0018] 3. No I-beam cross beam is arranged in the space on one side of the hoistway support frame, which can be used as a connecting side connected to the building. Description of the Drawings

Repeat the above process until two first connection cross beams 4 and two second connection cross beams 6 are installed. Then, install the upper upright column 3 corresponding to the lower upright column 2 to complete the docking of the first connection cross beam 4 and the second connection cross beam 6 with the corresponding upper upright column 3 respectively. Repeat the above process, dock the intermediate connection cross beam 7 in the intermediate connection groove 11 of the upper upright column 3, and then dock the first connection cross beam 4 and the second connection cross beam 6 in the top connection groove 12 of the upper upright column 3.
