Description

The present group of inventions is related to civil engineering and can be used in erection of multi-storey buildings/constructions.
Method for erecting monolithic buildings and technological equipment for its implementation is known (group of inventions, 1)
Method under the preferred embodiment includes erection of the building monolithic segment consisting of floor structure of the whole building and vertical structures of the upper tier/storey of the whole building. Main principle of the method: erecting the tier/storey floor structure of the whole building; following setting of concrete of said floor structure, pouring concrete of vertical structures of the next tier/storey of the whole building; curing the poured concrete until the design strength is achieved; erecting subsequent floor structure, etc. During performance of works, formwork rests on the already poured vertical structures of building. Technological equipment comprises, without limitation, travelling formwork and vertical shuttering panels. Travelling formwork includes lifting jacks with props, where U-shaped jack frames are installed. Posts of said jack frames are equipped with bearing plates. Frames located on both sides of the being erected vertical structures are connected together by rigid links. On bearing plates of said jack frame posts, carriages are mounted with possibility of travelling across said being erected vertical structures with vertical shuttering panels installed on them. During concreting, jack frames rest on vertical shuttering panels installed on the underlying vertical structures. Following the required strength of concrete is attained, jack frames are relocated to rest upon props of lifting jacks, and formwork is lifted to the next tier/storey.
The fact that jack frames during performance of works rest upon vertical shuttering panels imposes increased requirements to the strength properties of panels. It results in excessive consumption of metal during manufacturing of the panel frames, increased power consumption for relocation of formwork. Erection of multilayer vertical structures using known travelling formwork requires some time for the poured concrete to attain necessary strength in order to make it possible to re-rest jack frames on lifting jacks, which are installed on the already erected vertical structures, and to mold a cavity for the new layer. It extends the time of construction.
The present group of inventions is directed toward solution of following tasks: reduction of time for erection of buildings/constructions of monolithic reinforced concrete; reduction of material and labor costs.
The set task is resolved by the method for erecting vertical structures of building/construction of monolithic reinforced concrete including process steps of:

installing lifting jacks containing props enclosed in shells on the already erected structures; installing U-shaped jack frames equipped with posts and extendible supports on said jack props; connecting posts of said jack frames located adjacently on both sides of the being erected vertical structures by rigid links;

On posts of jack frames, panels can be installed with holes performed in their decks, where sleeves of elastic material are inserted. Following adjustment of width of molding cavity of the base (constructional) layer, reinforcing rods are inserted in holes with protruding ends located on both sides of the plane of panels. Following removal of panels and prior molding the next layer, a mesh cage is secured on the inserted reinforcing rods.
Vertical multilayer structures can be erected simultaneously for the whole building/construction.
The set task is resolved by the method for erecting the "floor structure - wall" segment of building/construction of monolithic reinforced concrete including process steps of:

installing lifting jacks containing props enclosed in shells on the already erected vertical structures; installing U-shaped jack frames equipped with posts and extendible supports on said jack props; connecting posts of said jack frames located adjacently on both sides of the being erected vertical structures by rigid links;
installing the floor structure formwork with reinforcement cages and installing reinforcement cages of vertical structures for the whole height of tier/storey with their connection to protruding reinforcement of previously erected structures and reinforcement of floor structure;
installing formwork panels for erection of vertical structures on the posts of jack frames; securing rigidly said panels located in single plane; adjusting the width of molding cavity; and connecting said panels located in parallel on the opposite side of reinforcement cage of the being erected vertical structures by means of tightening devices; locating bottom part of vertical shuttering panels at the level of the top part of floor structure formwork;
pouring concrete of the floor structure; pouring concrete into molding cavities of being the erected vertical structures at the final stage of setting of said floor structure concrete; imparting reciprocating and rotating or only rotating motion to shells enclosing props of lifting jacks; moving formwork panels away from the molded surface on one or both sides following stripping strength of the molded structures is attained; adjusting the width of molding cavity of the new layer and filling said cavity with molding material;
resting U-shaped jack frames upon the poured vertical structures by means of extendible supports following 30-40% design strength of the base (constructional) layer of vertical structures is attained; extracting lifting jack props with their enclosing shells from said molded vertical structures with subsequent filling cavities formed in vertical structures with concrete;
moving formwork panels away from the molded multilayer surface; resting props of lifting jacks upon the already erected base (constructional) layer of vertical structure; lifting U-shaped jack frames with formwork on the next tier/storey; and repeating the cycle for erecting the building/construction segment.

Prior to fill molding cavity of the base (constructional) layer with concrete, removable recess-forming cages can be hanged on the inner surface of formwork panels. Prior molding of the last (outer) layer, these cages shall be removed.
On posts of jack frames, panels can be installed with holes performed in their decks, where sleeves of elastic material are inserted. Following adjustment of width of molding cavity of the base (constructional) layer, reinforcing rods are inserted in holes with protruding ends located on both sides of the plane of panels. Following removal of panels and prior molding of the next layer, mesh cage is secured on the inserted reinforcing rods.
Floor structure and vertical multilayer structures of the whole building/construction can be erected simultaneously.
The set task is resolved also by application of travelling formwork comprising lifting jacks having props with U-shaped jack frames installed on them. In the base of jack frame posts, guides are secured, where holders of formwork panels of vertical structures are installed with possibility of travelling across said being erected vertical structures by means of the motor drive for their motion. At least one of the jack frame posts is provided with extendible support installed on it. On props of lifting jacks, shells are installed freely with possibility of rotation and vertical motion. Lower end of each shell is located in the base of the lower (end side) arm of lifting jack. Posts of adjacent jack frames located on each side of the being erected vertical structures are connected with each other by rigid links. Travelling formwork includes also vertical shuttering panels connected rigidly with each other and secured on the jack frame holders. Each said panel contains bearing frame with an edge profile around the panel perimeter.
Extendible supports of jack frames can be provided with motion drive and can be installed on each post of jack frames in guides located at an angle (preferably 45 degrees) to the being erected vertical structures. In addition, guides for motion of extendible supports located on posts of each U-shaped jack frame are arranged in opposite directions from posts along the being erected vertical structures.
Rotation drive of the shell can be installed on a pad located on its top end and contains a gear wheel engaging a gear ring secured on outer surface in the top part of the lifting jack prop.
The set task is resolved also by application of the vertical shuttering panel for erection of multilayer structures, which contains bearing frame with an edge profiles around the panel perimeter, a deck secured on said frame with holes performed in it, where sleeves of elastic material are inserted. On end face of the top edge profile of a panel, at least one bracket with holes for fixing elements to connect with the U-shaped jack frame can be secured.
In edge profiles of the vertical shuttering panels, holes for fixing elements to connect with other panels can be performed. In the panel deck and bearing frame elements, holes for tightening devices can be performed. Panel can be sized for the whole height of tier/storey.
The set of features of both every individual invention and the group of inventions, including structural elements (assemblies, parts, etc.), when they are used jointly, makes it possible to resolve the set task. Shells installed on the props of lifting jacks with possibility of rotation and vertical motion allow isolation of props in the process of structures concreting. In the process of implementation of methods for erecting structural elements of building/construction, load from the whole formwork is transferred to the previously erected vertical structures by means of jacks, unlike to panels as it follows from prior art. It makes it possible to decrease significantly amount of metal used to manufacture the frame of panels resulting in reduction of power consumed for relocation of formwork. Besides, it becomes possible to arrange additional layers of structures immediately following concrete of the erected base (constructional) layer achieves the stripping strength. Time to stripping of structures is less than time required for the poured concrete to set to a strength, when it becomes possible to transfer the formwork load on it by means of lifting jacks. As compared with prior art, it allows reduction of construction time. Installation of guides on the jack frame posts, where holders of the vertical shuttering panels are installed with possibility of motion across the being erected vertical structures, makes it possible, just as its provided by the prior art, to adjust the wall thickness, including reduction of the wall thickness of upper tiers/storeys, which contributes the decreased expenditure of construction materials. Extendible supports installed on posts of jack frames allow relocation of travelling formwork on the poured vertical structures and extraction of lifting jacks to continue performance of works. Application of removable recess-forming cages hanged prior concreting on the vertical shuttering panels, as well as panels with holes in their decks for inserting reinforcing rods to secure mesh cage prior concreting of the next layer makes it possible to improve bonding of layers of vertical structures. It increases reliability and quality of construction works.

In the specific embodiment as defined below, travelling formwork comprises lifting jacks with props 1, where U-shaped jack frames 2 are installed on. In the base of each post 3 of said jack frames, guides 4 are secured, where holders 6 of the vertical shuttering panels 7 are installed with motor drive providing possibility of their motion across the being erected vertical structures 5. Also, on posts 3 of the jack frame 2, extendible supports 8 are installed moveably. On props 1 of lifting jacks, shells 9 are installed freely with possibility of rotation and vertical motion. Lower end of each shell 9 is located in the base of the lower (end side) arm of lifting jack. Posts 3 of adjacent jack frames 2 located on each side of the being erected vertical structures 5 are connected with each other by rigid links 10. Travelling formwork includes also vertical shuttering panels 7 connected rigidly with each other and secured on holders 6 of jack frames 2. Each said panel 7 contains bearing frame with an edge profile around the panel perimeter. Extendible supports 8 of jack frames 2 are provided with motion drive and are installed on each post 3 of jack frames 2 in guides 11 located at an angle (preferably 45 degrees) to the being erected vertical structures 5. In addition, guides 11 are directed in opposite sides from posts 3 along the being erected vertical structures 5. It is evident that extendible supports 8 can be located only on the one of posts 3 of jack frames 2. In this case, extendible supports 8 on adjacent jack frames 2 will be located in the staggered order along the being erected vertical structures 5. Such an arrangement ensures reliable resting of the whole formwork on the being erected vertical structures following extraction of props 1 of lifting jacks from them. It is also evident that extendible supports 8 can be executed in the form of outriggers of the truck crane (supports of extendible, folding, pivotable and extendible, pivotable and folding types, etc.) and located on posts 3. Rotation drive of the shell 9 is installed on a pad located on its top end and contains gear wheel 12 engaging gear ring 13 secured on outer surface in the top part of the lifting jack prop 1. When props 1 are extracted from vertical structures 5, disengaging of gear wheel 12 and gear ring 13 occurs. Props 1 are lifted together with shells 9.
Travelling formwork comprises also vertical shuttering panels 7 containing bearing frame containing edge profiles around the panel perimeter. On end face of the top edge profile of panel 7, at least one bracket 14 with holes for fixing elements to connect with holders 6 of the U-shaped jack frames 2 can be secured. In edge profiles of the vertical shuttering panel, holes for fixing elements to connect with other panels can be performed. In the panel deck and bearing frame elements, holes for tightening devices can be performed. Panel can be sized for the whole height of tier/storey. For erection of multilayer structures, panels 15 can be used with holes 17 performed in their decks 16, where sleeves of elastic material are inserted. Also, for erection of multilayer structures, panels 7 can be used with removable recess-forming cages 18 hanged on them from the inner side.
Single-layer vertical structures are erected as follows.
Lifting jacks containing props 1 enclosed in shells 9 with U-shaped jack frames 2 provided with extendible supports 8 and installed on these props 1 are mounted on the already erected structures 5. Posts 3 of adjacent jack frames 2 located on each side of the being erected vertical structures are connected with each other by rigid links 10. Reinforcement cages of vertical structures are installed for the whole height of tier/storey and are secured to the protruding reinforcement of previously erected structures. Formwork panels 7 containing brackets 14 are secured to holders 6, and all panels 7 located in single plane are connected rigidly with each other. Width of molding cavity is adjusted by movement of holders 6 in guides 4. Panels located in parallel on the opposite side of reinforcement cage of the being erected vertical structures are connected by means of tightening devices. Concrete is poured in molding cavities of the being erected vertical structures 5. Reciprocating and rotational or only rotational motion is imparted to shells 9 enclosing props 1 of lifting jacks. When 30-40% design strength of erected structures is attained, U-shaped jack frames 2 are laid resting on the poured vertical structures 5 by means of extendible supports 8; props 1 of lifting jacks with their enclosing shells 9 are extracted from said vertical structures, while cavities formed in these structures are filled with concrete, and the formwork panels are moved away from the molded surface. Said cavities can be filled not for the whole height (not shown in figures). In this case, sockets are left for further installation of props 1 of lifting jacks. When the required strength of concrete is attained, props 1 of lifting jacks are placed resting upon the already erected structures 5, U-shaped jack frames 2 are raised with formwork on the next tier/storey and the cycle of erection of vertical structures is repeated. Vertical structures can be erected simultaneously for the whole building/construction.
Multilayer vertical structures are erected as follows.
First stages of erecting the base (constructional) layer are performed in just the same manner as described above.
When molded structures (constructional layer) attain the stripping strength, formwork panels 7 on one or both sides are moved away from the molded surface (an example is shown in figures, where panels are moved away only on the one side to form the second layer 22). Width of molding cavity of the new layer is adjusted and this cavity is filled with molding material. When 30-40% design strength of the base (constructional) layer is attained, U-shaped jack frames 2 are laid resting on the poured vertical structures 5 (constructional layer) by means of extendible supports 8; props 1 of lifting jacks with their enclosing shells 9 are extracted from said vertical structures (constructional layer), while cavities formed in these structures are filled with concrete. The formwork panels 7 are moved away from the molded multilayer surface, props 1 of lifting jacks are placed resting on the already erected base (constructional) layer of vertical structure 5, U-shaped jack frames 2 are raised with formwork on the next tier/storey and the cycle of erection of the multilayer vertical structures is repeated. In one of possible embodiments (Figs, 11,12), prior to fill molding cavity of the base (constructional) layer with concrete, the removable recess-forming cages 18 are hanged on the inner surface of the formwork panels 7 and removed prior molding of the last (outer) layer. Vertical structures can be erected simultaneously for the whole building/construction. Under another embodiment (Figs. 14,15), panels 15 (Fig. 13) are installed on posts 3 of jack frames 2. The deck 16 of said panels 15 is provided with holes 17 performed in it, where sleeves of elastic material are inserted. Following adjustment of width of molding cavity of the base (constructional) layer, reinforcing rods 19 are inserted in holes 17 with their ends located on both sides of the plane of panels 15. Following panels are moved away prior molding of the next layer, mesh cage 20 is secured on the inserted reinforcing rods 19. Vertical multilayer structures can be erected simultaneously for the whole building/construction. It is evident that outside the constructional layer it is possible to erect simultaneously two - facing and insulating - layers at once. In this case, panels 7 or 15 are moved away from the molded constructional layer on both sides and works are performed as it is described above.
The "floor structure - wall" segment of building/constructions is erected of monolithic reinforced concrete as follows.
Lifting jacks containing props 1 enclosed in shells 9 with U-shaped jack frames 2 provided with extendible supports 8 and installed on said props 1 are mounted on the already erected structures 5. Posts 3 of adjacent jack frames 2 located on each side of the being erected vertical structures are connected with each other by rigid links 10. The floor structure formwork 21 with reinforcement cages is mounted and reinforcement cages of vertical structures for the whole height of tier/storey are installed. Said reinforcement cages are secured to protruding reinforcement of previously erected vertical structures and floor structure. Formwork panels 7 containing brackets 14 are secured to holders 6, and all panels 7 located in single plane are connected rigidly with each other with their bottom part located at the level of the top of the floor structure formwork. Width of molding cavity is adjusted by movement of holders 6 in guides 4. Panels 7 located in parallel on the opposite side of reinforcement cage of the being erected vertical structures are connected by means of tightening devices. Concrete of floor structure is poured and at the final stage of its setting concrete is poured in molding cavities of the being erected vertical structures. Reciprocating and rotational or only rotational motion is imparted to shells 9 enclosing props 1 of lifting jacks. When 30-40% design strength of erected structures is attained, U-shaped jack frames 2 are laid resting on the poured vertical structures 5 (constructional layer) by means of extendible supports 8; props 1 of lifting jacks with their enclosing shells 9 are extracted from said vertical structures, while cavities formed in these structures are filled with concrete, and the formwork panels are moved away from the molded surface. Props 1 of lifting jacks are placed resting on the already erected structures, U-shaped jack frames 2 are raised with formwork on the next tier/storey and the cycle of erection of the said building segment is repeated. Floor structure and vertical structures can be erected simultaneously for the whole building/construction.
The "floor structure -multilayer wall" segment of building/construction of monolithic reinforced concrete is erected as follows.
First stages of works are performed in just the same manner as during erection of the "wall - floor structure" segment. When the base (constructional layer) attains the stripping strength, formwork panels on one or both sides are moved away from the molded vertical surface (an example is shown in figures, where panels are moved away only on the one side to form the second layer 22). Width of molding cavity of the new layer is adjusted and this cavity is filled with molding material. When 30-40% design strength of the base (constructional) layer of vertical structures is attained, U-shaped jack frames 2 are laid resting on the base layer by means of extendible supports 8; props 1 of lifting jacks with their enclosing shells 9 are extracted from said base layer, while cavities formed in vertical structures are filled with concrete. The formwork panels 7 are moved away from the molded multilayer surface, props 1 of lifting jacks are placed resting on the erected base (constructional) layer of vertical structure, U-shaped jack frames 2 are raised with formwork on the next tier/storey and the cycle of erection of the building/construction part is repeated. Possible embodiments of the method for erecting multilayer vertical structures are disclosed above in respective section of the present patent specification. Floor structure and multilayer vertical structures can be erected simultaneously for the whole building/construction.
Utilization of inventions makes it possible to reduce consumption of materials for technological equipment and power costs for this equipment relocation. Time required for erection of buildings/constructions with multilayer vertical structures is reduced. When works are carried out simultaneously at the whole building/construction, just as it is specified in the family patent, creation of the monolithic building segment including floor slab structure of building and vertical structures of the upper tier/storey is ensured. Furthermore, rigidity and strength properties of the erected buildings/constructions are improved, which makes it possible to utilize inventions efficiently during construction activities in seismic regions.
