Description

Field of technology: the invention relates to construction, namely to the construction of walls made of monolithic reinforced concrete.

Material: reinforced concrete.

A method of creating wall reinforced concrete, bilateral, mutually stressed structures, including the technological installation of a special universal (multi-purpose) formwork, filling the formwork with a vibrated concrete mixture, keeping the mixture to solidify and removing the formwork, characterized in that such walls consist of load-bearing columns (Fig. 1, 2 , 3, 4, 5, 6, p. 6) and monolithic piers (Figs. 1, 2, 3, 4, 5, 6, 1, 2), connecting them, which also perform a supporting function. These piers (the outer and inner parts of the wall) are located opposite each other and mutually tension each other with support columns, creating the effect of a vertical reinforced concrete truss. The upper and lower seismic belts (Fig. 2, 4, 6, Clause 7, 8) connect the mutually stressed parts of the wall (Fig. 1, 2, 3, 4, 5, 6, Clause 1, 2). After the completion of the construction of such walls, voids are formed in their middle (Figs. 1, 2, 3, 4, 5, 6, p. 4) of 100 × 250 × 25 cm in size (or any other design value), which are suitable for effective insulation able to significantly reduce heat loss during heating of the building. In addition, the construction process is accelerated due to the fact that there is no need to wait for the completion of certain construction operations, and in some of them, practically, there is no need. The design has seismic resistance and durability of the best building analogues.

State of the art

Analogs of the present invention are the following methods for the manufacture of frame reinforced concrete, monolithic and monolithic prefabricated structures.

1. An analogue of the proposed method is a frame system with a spatial frame frame or a frame-type structure, including the installation of formwork panels of columns, filling the formwork with concrete, and setting the formwork of beams and ceilings and filling them with the finished mixture, characterized in that the whole structure is performed in monolithic reinforced concrete, is the most durable and earthquake resistant. The system was first implemented in France at the end of the 19th century. (more precisely, in the department of Nor, in Turkuene, 1985. Spinning factory) by the architect F. Gennebik, which includes supports, runs, beams and floor slabs. Description in the book by Y. Stankova and I. Pehar. "Millennial development of architecture", Moscow. "Stroyizdat", 1984

In Soviet editions, this system of erection of buildings and structures is known as: "Frame-frame type construction." "Technology of construction production." Leningrad. "Stroyizdat". 1987, p. 227.

A similar method is common in Europe, Japan and other countries. Its disadvantage is the relatively long duration of the construction of the structure and the need to erect walls between the supporting columns, which do not perform the supporting function.

2. The method of construction, restoration or reconstruction of buildings, structures and the method of manufacturing building products and structures from stone-protective materials, mainly concrete for the construction, restoration or reconstruction of buildings, structures, characterized in that it uses a prefabricated monolithic frame using prefabricated multi-tiered ( on several floors) of columns and precast-monolithic floors, and the assembly of all finished concrete products is carried out without welding, using a plug joint. To pair the columns with the crossbars, in them at the level of the floors, sections with bare reinforcement reinforced with cross reinforcement ties are provided. Docking is carried out by passing additional reinforcing bars through the body of the column. The overlap consists of pre-stressed reinforced concrete slabs 60 mm thick, which serve as fixed formwork, and a monolithic-reinforced layer 100-140 mm thick, laid on top. When concreting the slab, the slab formwork, including the crossbars, is supported by the inventory support system. The absence of welded joints simplifies the assembly of the frame and does not require highly skilled workers. Patent for invention: No. 2107784.

This method does not have the strength of a monolithic structure, since it is precast and monolithic. Additional reinforcement of the structure occurs due to an increase in the consumption of reinforcement. Prefabricated elements are fastened together by a monolith. There is a doubtful time gain, since the entire construction process is divided into two parts (construction of prefabricated structures and a monolith) and the acceleration of the prefabricated part of the structure implies further strengthening of the structures with cast concrete, which also takes time. As with the previous analogue, the external walls of the building are erected after the construction of the supporting structure. This is also extra time.

3. A known design of formwork containing panels, fasteners and supporting elements. The disadvantage of this formwork is the high material consumption and the inability to manufacture multilayer structures, or structures of complex shape.

Figure 10 is a universal formwork.

A monolithic reinforced concrete structure made according to the proposed method of erecting a double mutually stressed reinforced concrete wall structure consists of the outer part of the wall - 1, the inner part of the wall - 2, the corner column - 3, the cavity for insulation - 4, the reinforcement of the columns - 5, wall (and intermediate) columns - 6, upper seismic belt - 7, lower seismic belt - 8, reinforcing mesh of the outer and inner part of the wall - 9, reinforcement of the seismic belt - 10. Universal formwork includes: smooth formwork - 11, made of metal sheet with a thickness of 2 mm and at reinforced with metal, the sides of the formwork - 12, made of a metal sheet 1 mm thick having ribs, the inner part of the formwork - 13, made of a metal sheet 1 mm thick reinforced with metal. All parts of the formwork are equipped with mounting holes - 14, necessary for the assembly of the formwork.

Preparation method.

The wall is made of reinforced concrete in two stages. First, using a universal formwork (figure 10) (the formwork corresponds to the figure with option 1 and 2, for the remaining proposed forms the formwork is developed individually), the elements of the outer part of the wall are poured (figure 1, 2, 3, 4, 5, 6, p .1), and subsequently the inner part of the wall (Fig. 1, 2, 3, 4, 5, 6, clause 2). In this case, between the outer and inner parts of the wall, bonds are formed in the form of continuous reinforced columns (Figs. 1, 2, 3, 4, 5, 6, p. 6), with a section of 300 × 400 mm (or any designed section), after 1000 mm (and more). Columns (figures 1, 2, 3, 4, 5, 6, p. 6) are formed from the confluence of monolithic elements of the outer and inner parts of the wall (figures 1, 2, 3, 4, 5, 6, claim 1, 2 ) The external and internal parts of the wall, being at a distance of 250 mm from one another, mutually tension each other at places where their structures merge into columns and at places of confluence with seismic belts (Figs. 2, 4, 6, item 7, 8). The outer and inner parts of the wall have reinforcement (Fig. 1, 2, 3, 4, 5, 6, Clause 9) associated with the reinforcement of columns and seismic belts (Fig. 2, 4, 6, Clause 10). At the same time, the design works like a rectangular farm, located vertically. The upper seismic belt (Fig.2, 4, 6, p. 7) attracts to each other the external and internal parts of the wall, reinforcing them additionally. The same role is played by the lower seismic belt (Fig. 2, 4, 6, p. 8), which provides mortgages (Fig. 2, 4, 6, p. 10), necessary for reinforcing all elements of the wall. In this case, parts of the mutually stressed column (Figs. 1, 2, p. 6) at the top and bottom turn out to be attracted to each other by the upper and lower seismic belts (Figs. 2, 4, 6, p. 7, 8). All cavities (figures 1, 2, 3, 4, 5, 6, p. 4) located in a mutually stressed wall are insulated with concrete on all sides. For greater heat conservation, the inner part of the wall (Fig. 1, 2, 3, 4, 5, 6, p. 2) is poured from concrete with the addition of expanded clay. Concrete in the structure vibrates. The present invention retains all the elements of frame structures made of monolithic reinforced concrete, with the only difference being that the number of load-bearing columns (Figs. 1, 2, 3, 4, 5, 6, p. 6) increases, and castings are added in between the columns simultaneously with the columns, external and internal, monolithic with columns, wall parts, which are continuous reinforced membranes between columns and seismic belts along the entire height of the wall with a thickness of 70-80 mm (Figs. 1, 2, 3, 4, 5, 6, p. 12).

Compared with analog 1. When pouring a frame reinforced concrete structure, according to the most common practice, columns with a section of 40 × 40 cm are installed after 6 meters. After that, the formwork of beams, beams and ceilings is installed on the columns. Formwork installation, reinforcing, concrete pouring, curing and dismantling on medium-sized buildings takes up to two months. Two weeks after the formwork (which also takes at least a week), builders can begin to erect wall structures of external and internal walls from bricks, blocks, etc. This is the most reliable and most common way of building buildings in Europe.

The proposed method of erecting a bilateral mutually stressed wall structure according to the principle of reliability resembles the described analogue, but it is much stronger.

- Columns when using the method of erecting a double mutually stressed reinforced concrete wall structure are located at a distance from 100 cm to 150 cm from each other (Fig. 1, 2, 3, 4, 5, 6, p. 6). At a distance of 6 meters in the wall are not 2, but 4-5 columns. The section of the additional columns is not 40 × 40, but 40 × 30 cm, since the corner columns still have a section of 40 × 40 cm. In total, the total width of the supporting columns in the proposed method of walling is from one and a half to two meters on a span of 6 meters. In this case, the outer and inner walls also perform a supporting function and increase the area of the bearing surface of the columns by almost 2 times.

- Unlike analog 1, walls are erected simultaneously with columns. The wall reinforcement, as well as the column reinforcement (Fig. 1, 2, 3, 4, 5, 6, items 5, 9), is connected with the seismic belt (Fig. 2, 4, 6, items 7 , 8) and strengthens it. It is an additional support for the entire structure. The walls in analogue 1 are neither bearing nor associated with the seismic belt. In the proposed method, there is no need to further waste time on the construction of walls in the spaces between the supporting columns.

- Unlike the prototype analog, the method of erecting a double mutually stressed reinforced concrete wall structure allows you to erect walls much faster. In the presence of the required number of universal formwork (figure 10), this process can take two weeks, after which you can proceed with the filling of the seismic belt and overlap at the same time.

- Unlike analog 1, walls do not need plaster. When implementing the method of erecting a double mutually stressed reinforced concrete wall structure, this issue is solved by smooth casting in metal formwork. The external parts of the walls, as well as the internal ones, can be putty and painted.

In comparison with analogue 2, patent No. 22107784.

Unlike prefabricated-monolithic structures, the proposed method, like the prototype analogue, is stronger and more stable. Prefabricated monolithic structures are built faster than analog prototype structures and make it possible to build several floors at the same time by installing 12 meter columns and installing finished crossbars, but prefabricated structures lack strength due to the fact that they are partially finished and partially made of solid concrete is already at the design site. In fact, this is not a monolith. Unlike the prefabricated-monolithic structure, the method of erecting a bilateral mutually stressed wall structure made of reinforced concrete wins in erection time due to the presence of external and internal parts of the walls (Figs. 1, 2, 3, 4, 5, 6, items 1, 2 ), and not by changing the sequence of construction. In addition, with the precast-monolithic method, there remains the need to erect separately from the frame wall structures and separately carry out work on their insulation. When constructing a bilateral mutually stressed wall structure, more time is spent on the construction of the structure by maintaining the usual sequence of construction (as in frame-type structures), but there is no need for subsequent construction of the walls and their insulation, which ultimately gives a huge gain in time.

Wall reinforcement

Reinforcement of the wall structure begins with the lower (zero) seismic belt (Fig.2, 4, 6, p.8). In the seismic belt, it is planned to produce pieces of corrugated reinforcement connected with the longitudinal reinforcement of the seismic belt 3 cm from the outer edge of the seismic belt and 3 centimeters from the inside (Figs. 2, 4, 6, 10).

A horizontal “thread” of reinforcement is welded to the external mortgages with a diameter of 12 mm around the entire perimeter of the house. Further, when installing the formwork of the external wall elements in the right places, vertical reinforcement, corrugated or smooth, is welded to this “thread”, and a mesh with a mesh of 100 × 100 mm, wire thickness of 3-4 mm is tied to the vertical reinforcement with a knitting wire , 2, 3, 4, 5, 6, 7, 8, 9, item 9).

In places of future columns, vertical reinforcement is double. All fittings are produced above the wall formwork by 1000 mm. Subsequently, all of it is associated with the reinforcement of the upper seismic belt (Figs. 2, 4, 6, p. 7) and can be used as a Mauerlat for erecting a roof or as a basis for linking reinforcement of the next floor. Reinforcement with the method of erecting a double mutually stressed reinforced concrete wall structure is carried out according to the existing SNiPs and ENiRam.

Universal formwork (figure 10)

The versatility of formwork lies in several of its qualities.

- This formwork is designed for filling both the outer and inner walls, with supporting columns and wall elements.

- This formwork eliminates the need to plaster the house both inside and outside.

- This formwork allows you to quickly build walls.

- It can be used for pouring other concrete products, like conventional formwork.

- The formwork is quickly mounted and quickly disassembled. Special devices, very simple in operation, facilitate its installation and alignment in three planes.

- One set of formwork, worked out for a multi-storey building, effectively repeats the walls of each floor. Existing special equipment can be used for work.

As the formwork, simple smooth metal sheets are used, reinforced with a profile pipe 25 × 25 mm (Fig. 10, item 11), as well as the inside (Fig. 10, item 13) and sidewalls (Fig. 10, item 12) fastened together through mounting holes (Fig.10, p.14), short bolts and bolts with restrictive tubes of the required length. Universal formwork saves concrete at least 2 times while reducing labor costs and creates effective opportunities for wall insulation.

A bilateral mutually stressed structure is lighter than usual by at least 50%, with an additional margin of safety.

Heat Saving Effect:

- The method of construction of a double mutually reinforced concrete wall structure. With a wall thickness of 40 cm, the layer of internal insulation is not less than 25 cm, while the inner part of the wall is poured from insulated expanded clay concrete 7 cm thick. The insulated part is at least 320 mm (Figs. 1, 2, 3, 4, 5, 6, p. 4, 2).

- The option of erecting a bilateral mutually stressed wall structure when creating a multi-storey building (Fig.5, 6) provides for external insulation. Since the column (Fig.5, 6, p.6) is full-bodied to the thickness of the entire wall, there is a danger of creating a cold bridge. In order to exclude cooling of the columns, it is supposed to use external insulation as is customary in places with a cold climate. In this case, the intra-wall cavities (Figs. 5, 6, p. 4) are either filled with insulation, or remain empty to create the effect of a thermos.

- The presence of cavities inside the wall allows you to use almost any insulation material, despite its fragility and shrinkage. All insulation material is isolated by concrete structures and protected from external influences.

The structure of the universal formwork for the construction of a bilateral mutually stressed wall structure.

Formwork consists of three main parts and individual devices.

- Smooth formwork (figure 10, item 11.). Size 1250 × 2500 mm. The thickness of the iron is 2 mm. The profile square is reinforced with a 25 × 25 mm pipe. On the lateral edges of the front formwork there are small mounting holes (Fig. 10, p. 14) for fastening to adjusting devices and other parts of the formwork.

- Internal formwork (Fig. 10, items 12, 13). It is made of metal 1 mm thick. It has a complex shape, which should create along the edges of the product the outer part of the wall, stiffeners. On the lateral edges of the hole for fasteners with sidewalls (Fig. 10, item 12) of the inner formwork (Fig. 10, item 13), which are also made of 1 mm thick sheet. The sides have mounting holes, similar in placement to the holes on a smooth formwork. The sides (Fig. 10, item 12) are combined with a smooth formwork (Fig. 10, item 11) and are attached to each other and to the adjusting devices by bolts. Internal and smooth formwork closes a complex vertical space with a height of 2500 mm and a width of 1200 mm, with stiffeners along the edges. These stiffeners are ribs, forming, in the future, the column. After filling the inner part of the wall, this cavity becomes limited on all sides.

- Adjusting device. It is assumed that this will be an analogue of existing devices (struts, braces, rods ...), with the only difference being that it will be possible to mount formwork elements to them and they will have adjusting devices that allow changing the formwork slope by 5-10 degrees in two vertical planes.

Additional devices

1. Formwork columns. The usual multi-dimensional formwork, consisting of 4 panels.

2. A special internal formwork for setting angular formwork with the simultaneous filling of the corner column, so that the corner of the building is monolithic.

3. Element of half formwork for non-standard gaps in external walls.

4. Formwork for window and door jumpers.

5. Internal wooden formwork for installation inside the external structure for filling the internal walls.

6. Vibrators mounted on the front, smooth formwork on special bolts.

7. Adjusting devices.

Preparation of formwork for work.

Before work, the inside of the formwork is lubricated. It can be: diesel fuel, solid oil, drying oil, wax, paraffin, epoxy ...

Before installing a smooth and internal formwork, wood or rubber gaskets are inserted between them. This is done so that the reinforcing mesh does not fit snugly against a smooth formwork (Fig. 10, item 11). Between the sides of the inner (figure 10, p. 12) formwork and the innermost formwork (figure 10, p. 13) a disposable strip of cardboard or a special multi-cycle strip of rubber is inserted to facilitate formwork.

In order to prevent the reinforcement from adhering to the outer formwork, a special method is used to link the reinforcement with wire that repels the mesh from the formwork.

With the help of adjusting devices, the vertical setting of the formwork is adjusted in level in 2 planes. Universal formwork is not as bulky as that used in industrial construction. Nevertheless, it is possible to create larger formwork, depending on the design need.

Thus, all the necessary formwork is exposed, after which concrete is poured. Concrete filling is carried out by a mobile automobile concrete pump. In this case, all external wall elements can be flooded in one working day. The formwork installation on the finished foundation can be carried out for a period of 3 to 5 days. The volume of external elements of the wall of a house measuring 10 × 10 meters is about 10 m ^{3 of} concrete.

Formwork can be carried out as early as 3 days from the moment of pouring concrete.

Total: from 5 to 7 days for the manufacture of the outer part of the wall.

Making the inner wall and its insulation.

After pouring the outer wall, the formwork is used to fill the inside of the wall. External even sheets of formwork (Fig. 10, item 11) are attached to adjusting devices on the inner side of the walls. For this, fixing bolts are used. Through mounting holes, fasteners are carried out using screws of the required length through tubular stops. Inside the manufactured external wall elements, plywood formwork is mounted in a special way, to which a foam sheet is attached. The goal is to facilitate the dismantling of plywood formwork after the construction of the inner part of the wall. Smooth formwork self-tapping screws are screwed to this plywood through tubular stops. After the construction of the inner part of the wall, the plywood formwork is dismantled through the top of the wall. The thickness of the technological foam layer can be from 20 to 250 mm. At the time of installation of the formwork of the internal walls between the foam and the smooth formwork, a reinforcing mesh is mounted (Figs. 1, 2, 3, 4, 5, 6, 7, 8, 9, Clause 9). The filling of the inner wall is carried out with expanded clay concrete.

After the construction of the inner part of the wall and formwork, the structure is insulated with one of the existing methods.

- Cavities (figures 1, 2, 3, 4, 5, 6, p. 4) can remain empty. In this case, when pouring a seismic belt or intercolumn beams, the cavities from above are covered with pieces of fiberboard to prevent concrete from spilling into the cavity.

- Cavities can be pumped with foam concrete or clogged with foam. In this case, there is no need to cover the cavity, since the insulation is quite rigid.

- Cavities can be pumped with penoizol or clogged with mineral wool. Here it is necessary to isolate the cavities, since the insulation is soft enough and can sag under the pressure of concrete.

Wiring.

The electrical wiring system is planned before filling the internal walls. Corrugated pipes are left in the formwork for further laying of electric cables. Corrugated pipes are protected by plugs, and the ends of the transport wires are led outside the formwork in places where there are mounting holes, or in the lower part of the formwork or a 3-4 mm hole is drilled in the right place. The electrical wiring is installed after the completion of the filling of the walls. Main electric cables are also laid at the bottom or at the top of the walls so that subsequently the gates can be arranged for the missing electric cables on a loose concrete wall. Heating can also be planned in advance. The heating pipes are fixed to the elements of the external wall so that they are flooded with concrete of the internal wall. At the same time, the strength of the walls will not be affected.

Removing the inner wall.

After the claydite-concrete has hardened, the fixing screws on both sides of the wall are first unscrewed and a smooth formwork with internal plywood is released. However, all formwork remains in place. In the adjusting devices, special crossbars are provided in order to arrange scaffolds on them. Workers pull out special rails from the scaffolds with plywood fixed to them manually or using a small crane. A cavity is freed in the wall, and the resulting void can be filled or not at the discretion of the customer. It can be filled and then, after completion of construction with penoizol, through tubular restrictive holes. You can fill the void with clay or any other insulation on top before filling the seismic belt.

A simplified way of wall insulation.

Instead of insulation, you can use simple reeds, empty plastic bottles, non-toxic production waste.

For the installation of internal formwork from 3 to 5 days, plus concrete pouring 1 day and dismantling after 1 day.

Total: from 6 to 8. In total, no more than 15 days for the construction of walls.

Further actions.

After the construction of the walls, you can begin to fill the seismic belt with crossbars on the finished intermediate columns and elements of the internal and external walls, or beams with ceilings. If there is a sufficient amount of the necessary formwork, all this is done quite quickly. Three days after pouring the floor, without dismantling the formwork of the floor, you can start erecting, in the same way, the walls of the next floor or making the roof.

Using the method of construction of a double mutually reinforced concrete wall structure with internal insulation for the construction of multi-storey buildings.

For the construction of multi-storey buildings, an individual constructive solution is required, allowing to present calculations of the required wall thickness and calculations of reinforcement. Based on this, an individual set of universal formwork is made, which can be used on each subsequent floor. The thickness of the walls does not matter. It can be any given size. The thickness of the insulation directly depends on the thickness of the walls. The principle of pouring a double mutually reinforced concrete wall structure does not change. One advantage remains obvious: the method of erecting a double mutually stressed reinforced concrete wall structure is lighter than its concrete counterparts and therefore is able to facilitate the entire multi-story structure.

The mutual tension of the wall structure is achieved due to:

- continuous reinforcement of the internal, external parts of the walls associated with the reinforcement of columns and seismic belts;

- the fact that the reinforcement of the external and internal parts of the wall is equidistant from each other, and in combination with the reinforcement of columns and seismic belts, both can work to break and compress in the general design, like a volumetric truss.

A concrete wall, which is a three-dimensional, reinforced concrete truss, is designed to withstand loads in three planes.

1. Vertical loads. In the event of soil subsidence in any part of the structure, the vertical load will be distributed in such a way that one of the seismic belts will work to break, and the other to compress, and parts of the outer and inner walls will serve as jumpers of this vertical truss. If soil subsidence occurs on one side of the building, then the upper seismic belt will work for breaking, and the lower one for compression. If soil subsidence occurs in the middle of the wall, then the lower seismic belt will work for breaking, and the upper one for compression. The greater the reinforced distance between them, occupied by columns and reinforced parts of the wall, the greater the load can withstand the entire structure.

2. Lateral loads turn the wall structure into a side truss, either vertically standing or horizontally lying. In this case, the outer and inner parts of the wall in the reinforcement complex will work, if one compresses, the other breaks, and intermediate columns will play the role of the truss jumpers. For example, with a strong crosswind, tension is created in the upper part of the wall. In this case, the outer part begins to work in discontinuity, and the inner part in compression. Seismic vibrations can create pressure on the center of the wall. If the wall is able to withstand the impact of the elements, then in this case, the inner part of the wall will work to break, and the outer part will compress.

Based on the fact that the principle of a volumetric truss is used in the construction of the wall, in the case of loads on the structure from either side, any part of the wall can work both in tearing and in compression. In this case, the opposite parts will complement each other’s work, logically distributing the “gap” and “compression” functions between the parts of the wall, depending on the circumstances, while these functions will always correspond to the opposite parts of the wall. In general, this is the mutual tension. The mutual voltage of the opposite parts of the wall in accordance with the circumstances.

By implementing this invention, the following results are achieved.

1. An earthquake-resistant wall structure is created that is not inferior in strength to existing methods of walling. The strength of the wall is achieved through effective reinforcement, which creates the effect of the mutual tension of the outer and inner walls of the structure.

2. The erection of the wall structure is twice as fast as conventional masonry and is conveniently combined in time with the erection of monolithic ceilings in high-rise buildings.

3. This method provides a new approach to wall insulation, in contrast to the one that is generally accepted in our time, namely wall insulation of buildings from the outside. The proposed method of erecting walls makes them warm and faster, more technologically advanced, efficient and much less expensive.

4. This method of building walls requires an order of magnitude less cost.
