Description
Technical Field
The invention relates to the field of buildings, in particular to a method for installing a precast concrete integral bathroom.
Background
The bearing structure of most houses in China is formed by casting cast-in-place concrete, the bearing structure of a part of the houses is a multi-layer building adopting prefabricated plates, the plate body structure of a sanitary room part of the houses is also formed by casting cast-in-place concrete, and the sanitary room part of the houses is generally formed by casting cast-in-place caisson structures. Certainly, few parts also adopt whole bathroom, and compared with traditional bathroom, whole bathroom has advantages such as simple to operate, space utilization is high, the material is good, watertight. In the prior art, an integrated bathroom is mainly manufactured by using glass fiber reinforced plastics (glass molding compound, abbreviated as Sheet molding compound) or GPR (glass reinforced plastic, FRP, glass reinforced thermosetting plastic) to form an integrated bathroom bottom plate and an integrated bathroom wall plate, and then the bathroom bottom plate and the wall plate are fixed to form an integrated bathroom structure. In order to obtain the balance between strength and thickness, a reinforcing rib or a vertical rib is provided under the bathroom floor of the related art to reduce the thickness of the floor while ensuring the strength of the floor. However, since the bottom plate is placed on the sinking floor via the reinforcing ribs or the vertical ribs, a sense of rattling is generated when the bathroom bottom plate is stepped on, and the living comfort is lowered. In addition, due to insufficient research and grasp on the quality of domestic material commodities, the manufactured product has gradually advantages in price, but cannot meet the requirements of Chinese people in texture, so that people tend to use the precast concrete integral bathroom. However, if the prefabricated concrete integral bathroom is installed on the same floor in a one-by-one mode, the prefabricated concrete integral bathroom is bound by the capacity of manufacturers, and the construction period is also seriously influenced. Therefore, a simple and convenient method for transporting and installing the prefabricated concrete integral bathroom without influencing the construction period needs to be found.
For example, chinese patent No. CN201110064450.3 discloses a prefabricated toilet and a method of constructing and installing the prefabricated toilet. The construction method of the prefabricated toilet comprises the following steps: the bottom plate unit of the prefabricated toilet and the lower parts of the four wall units are built through a bottom steel die and a vertical steel die, concrete meeting requirements is poured into an inner space surrounded by the bottom steel die and the vertical steel die, the vertical steel die and a cavity pipe are removed after the concrete reaches a certain strength, so that the bottom plate unit of the prefabricated toilet and the lower half part of the prefabricated toilet are formed, structural steel bars forming the upper part of the wall unit and the outline of the ceiling unit are butted with vertically exposed steel bars at the top of the lower half part of the prefabricated toilet, and a complete frame of the four wall units and the ceiling unit is formed. When the structural steel bars of the upper parts of the wall units and the outlines of the ceiling units are lapped in the lower half part of the prefabricated toilet, upper inner side aluminum molds are required to be arranged on the inner sides of the frames of the four wall units and the ceiling units. The inner side aluminum die is installed in the profile structural steel bar of the prefabricated toilet through manpower, and the operation of workers is difficult because the inner space of the prefabricated toilet is narrow. In addition, the number of the inner side aluminum modules is large, the installation difficulty is large, and the installation time is long. Because inboard aluminium mould is through artifical installation, in order to make things convenient for the manual work to lift up the installation, the weight of inboard aluminium mould is lighter, but pours into the concrete back, and inboard aluminium mould is easily warp by the oppression of concrete, when waiting that the concrete condenses and demolish the mould, still need further polish the wall unit or the ceiling unit of concrete and make it level. And the concrete is poured manually on site, and the verticality of the side mold is difficult to adjust, so that the phenomenon of inclination often exists.
For another example, KR20180083256 relates to an assembled bathroom, but the assembly of the bathroom is performed by means of field bonding, which is technically demanding for assembly personnel, and the problem that the assembly is not smooth enough exists.
For another example, chinese patent No. CN201621347523.4 discloses a special hanging basket for an integral toilet hanging, which comprises a hanging basket bottom plate, a guardrail, a hanging basket balance frame, a hanging basket shock absorber and a hanging basket safety lock, wherein the guardrail is installed at two sides of the basket bottom plate, the hanging basket shock absorber is installed at one side of the hanging basket bottom plate facing a target building, and the hanging basket balance frame is connected with the hanging basket bottom plate through a hanging rope and is placed right above the hanging basket bottom plate; the hanging basket safety locks are arranged at the front end and the rear end of the special hanging basket. The special hanging basket for installing the integral toilet provided by the device improves the transportation efficiency of the integral toilet on one hand and improves the stability of the integral toilet in the transportation process on the other hand, but no reinforcing protection block is arranged for hoisting the hanging basket and the integral toilet, so that potential danger exists.
In the field of transportation and installation of precast concrete integrated bathrooms, many practical problems to be treated urgently in practical application of the precast concrete integrated bathrooms have unreported specific solutions.
