(54) METHOD FOR CONSTRUCTING A BUILDING BY THE METHOD OF RISING FLOORS AND COVERS

one

The invention relates to the construction and can be used in multi-storey buildings with reinforced concrete stiffening core, constructed by the method of lifting, floors and ceilings.

There is a known method of building a building using the method of lifting floors and ceilings, which includes making a core of rigidity to the entire height of the building, installing columns, concreting a package of floor slabs with a subsequent rise to design marks 1.

There is also known a method of erecting a building by the method of raising floors and floors, including installation of columns, making a package of floor slabs with their subsequent lifting to design marks with hoists with cargo bars, concreting the stiffening core 2.

The disadvantage of known solutions is that the construction of the building with such a sequence is laborious. In addition, the seismic resistance of a building under the action of horizontal forces is not sufficiently ensured.

The purpose of the invention is to reduce the labor-intensive work while increasing the stability of the erected building by horizontal loads.

This is achieved by the fact that in the method of erecting a building by raising floors and floors, including installing columns, making floor slabs and then raising them to design marks with elevators with cargo drafts, concreting the core stiffness simultaneously with installing columns of rigidity walls inside and outside of it, pair inventory counters are installed, they are interconnected by spacers on which they mount lifts with cargo rods, and in the manufacture of a pack of plates In the places where the stiffener walls are formed, they are made through closed slots in the plan with a configuration corresponding to the stiffener configuration, and the working reinforcement of the plates is passed through the slots, and at the intersection of the axes of the stiffener walls in the floor slabs the collars are installed, covering paired racks, Then, floor slabs are lifted on a floor-by-floor basis, after installation of which the walls of the core of the stiffening shaft are concrete-cast on a floor-by-floor basis, and after the latter is erected over the entire height of the building, tare racks with spacers dismantle. FIG. 1 shows paired inventory columns with struts and collars, during installation; in fig. 2 - stiffening reinforcement armature during installation; in fig. 3 - draw rigidity in the process of concreting from the bottom up. The method of erection of a building by the method of lifting floors and floors with reinforced concrete core of rigidity is carried out as follows. Simultaneously with the installation of the columns of the building 1, pair inventory racks 2 are installed at the intersections of the axes of the wall of the core of the rigidity core inside and outside the platform. Next, the racks are interconnected by spacers 3, on which the lifts 4 are mounted with the cargo bars 5, and then proceed to concreting the slab package overlaps 6, in the places where the walls of the core of formation of the rigidity of the slab are formed, through through closed slots 7 are configured with the configuration of the rigidity core, and the working reinforcement 8 of the plate is passed through the slots. Then, at the intersection of the axes of the core of rigidity in the slabs, collars 9 are installed, covering paired racks 2. Then, floor-by-floor lifting of the slabs is performed, and after they are installed, the walls of the core of the stiffener core 10 are concrete-cast 2 with spacers 3 dismantle. The method according to the invention makes it possible to obtain a solid monolithic structure of the core both over the whole section and at the height, thereby increasing the strength and rigidity of the core under the action of horizontal loads. In addition, it becomes possible to combine floor slabs and internal hardness floor slabs into a single system, which naturally reduces the laboriousness of work both in the manufacture of a package of floor slabs and during lifting installation work. Finally, such a design of the core in the framework system allows external and internal floor slabs to be used as stiffeners for the walls of the core of the core, which significantly increases the load-bearing stability of the stiffener core. The invention The method of building a method of raising floors and floors, including the installation of columns, the manufacture of a package of floor slabs and their subsequent rise to design marks with hoists with loading rods, concreting the core, characterized in that, in order to reduce the complexity of work and increase the stability of the erected building on horizontal loads, simultaneously with the installation of columns of the building relative to the intersection of the axes of the walls of the core of stiffness inside and outside it set the pair inventory The racks are interconnected by struts on which they install hoists with cargo drafts, and in the manufacture of a package of floor slabs in places where the stiffener walls are formed, they are made through closed in plan slots with a configuration corresponding to the stiffener core configuration the plates are passed through the slots, and at the intersections of the axes of the walls of the core of rigidity in the slabs, collars are installed, covering the paired racks, then floor-by-floor lifting of the slabs, after Application to the design position where each floor concreted walls of the core hardness of the barrel, and in the construction of the latter on the entire height of the building inventory racks with spacers dismantle.
