Description
Technical Field
The utility model relates to an energy-concerving and environment-protective steel construction concrete prefabricated plate and install elevator vestibule additional thereof uses and installs elevator construction field additional at the outer wall for connect original building body and newly-built install the elevator additional.
Background
An elevator is not designed in the construction of an old building, and a plurality of residents have been in the way of old people, and only a building with five or six floors originally climbs. With the aging population and the continuous improvement of the living standard of people, the demand of people on elevator equipment is continuously increased, the elevator equipment is not exclusive to high-rise buildings any more, and the elevator is added to the short and old buildings (two floors, three floors and seven floors, eight floors).
The old house does not reserve the well of elevator equipment, and most of current additional installations schemes are that the steel construction well is set up earlier at original building outer layer, then installs elevator equipment again. However, because of the particularity of the elevator installed outside the building, no excellent solution is available at the connection part between the steel structure hoistway and the original building body. At present, because the innovation force of a plurality of enterprises engaged in elevator installation is insufficient, the elevator installation industry is developed for decades and stays in the traditional construction process of a steel structure and a cast-in-place concrete precast slab, and the innovation is not always provided, so that a solution which can improve the quality, ensure the construction safety, improve the construction efficiency, protect the environment and save the energy is urgently needed to be proposed.
The existing concrete precast slab 1' adopts the construction process (as shown in figures 1-3) as follows: firstly, connecting an original building body and a steel structure shaft by a steel structure steel beam 10'; paving a steel bearing plate 2 'on the steel beam 10'; welding the shear nails 3' on the steel bearing plate; paving floor reinforcing steel bars 5' on a steel bearing plate; fifthly, pouring concrete 4' on the steel bearing plate; (6) after the additional elevator is installed, constructing and filling an area between the additional elevator and the concrete to form a filling area 8'; (7) because the left side and the right side of the corridor are the exposed steel structural steel beams 1 ', the corridor needs to be cast and wrapped to form a casting area 9'; (8) paving surface tiles 6 'on the concrete 4', the filling area and the pouring area; (9) and after the upper part is completely finished, the operation of the bottom suspended ceiling 7' is carried out.
It has more disadvantages:
1. the two ends of the cast-in-place concrete precast slab are not in stressed connection with the original building body or the additionally-installed elevator, and the connection of the cast-in-place concrete precast slab and the steel beam completely transfers force to the steel beam by virtue of the shear nails to participate in stress;
2. the construction process is too complicated, and the construction period is long: after the floor part of the whole corridor is poured, one end, far away from the original building body, of the floor part needs to be inwardly protruded to additionally install an elevator shaft, after the elevator is installed, secondary ground construction treatment (namely a filling area) is carried out by combining the sill position of the elevator, and the steel beam is poured to expose the position, so that the work cannot be completed at one time. The construction difficulty is increased, and the construction period is prolonged;
3. the potential safety hazard of construction is big: (1) because most of the elevators are installed in old communities, once the elevators are installed for construction, the original living area becomes a construction site, and pouring raw materials are piled up to occupy the site; (2) in the decoration construction link, when corridor concrete is poured, the bottom is still a passage through which people pass, and the construction safety of objects falling from the upper part during construction operation is extremely high; (3) the longer the construction period is, the greater the potential safety hazard is;
4. transportation of sand and stone materials required for concrete pouring, concrete stirring and pouring can cause environmental pollution and noise pollution;
5. the construction process of suspended ceiling and floor tile is related, because the area of each corridor decoration part for installing elevator is generally 30-50m2The construction amount is too small, the process is very complicated, and the construction cost of the enterprise is doubled.
Therefore, the energy-saving and environment-friendly steel structure concrete precast slab and the elevator corridor additionally provided with the same have the urgent needs, wherein the energy-saving and environment-friendly steel structure concrete precast slab has the advantages of reasonable stress, simple structure, capability of completing one-time construction, simple construction process, short construction period, reasonable stress, energy conservation, environment friendliness, high efficiency and safety.
