Description

Technical field

The invention relates to the field of construction, namely to reinforcing and molding blocks for the manufacture of precast concrete and reinforced concrete integral and composite structures and elements, including reinforced concrete driven piles, columns and racks of various sections with and without cavities, pressure and pressureless reinforced concrete pipes and etc.

State of the art

Known reinforcing and molding blocks (patent AT 354709T, publ. March 15, 2007), including only the form. Therefore, for the formation of the upper and lower faces of the precast element, by means of which it is joined with adjacent ones, considerable labor costs for their grouting are required. At the same time, their normals and the longitudinal axis of the prefabricated element are not aligned. At the joints, a fracture is formed. To connect adjacent prefabricated elements, the installation of embedded parts is necessary. Ensuring high accuracy of their installation requires large labor costs, as well as the use of additional mounting devices.

Known rebar and molding blocks (patent JP 58160431, publ. 09/22/1983; patent JP 60242216, publ. 12/02/1985; patent JP 62045821, publ. 02/27/1987), comprising a mold, lower and upper covers, which are interconnected and form a fixed molding block. Therefore, the manufacture of a prefabricated element is associated with high complexity and material consumption. For the connection of prefabricated elements made in such a reinforcing-molding block, the use of additional overhead parts is necessary. Ensuring the high accuracy of their installation requires significant labor costs, as well as the use of additional mounting devices.

Reinforcing and molding blocks are known (copyright certificate SU 1085837, publ. 04/15/1984; patent JP 2175105, publ. 07/07/1990; patent JP 2266019, publ. 10/30/1990; patent JP 3009808, publ. 17.01.1991; patent JP 5096525 , publ. 04/20/1993; patent JP 6031721, publ. 02/08/1994; patent JP 2005240504, publ. 08.09.2005; patent JP 2007230187, publ. 09/13/2007), comprising a mold with removable lower and upper covers. They do not provide for the possibility of forming a prefabricated element with embedded parts providing for its connection with adjacent prefabricated elements. It is necessary to additionally install such embedded and overhead parts. Ensuring the high accuracy of their installation requires significant labor costs, as well as the use of additional mounting devices.

Known reinforcing and molding blocks comprising a mold with lower and upper covers and a reinforcing cage (patent RU 361580, publ. 07.12.1970; patent JP 5171737, publ. 07/07/1993; patent JP 8326309, publ. 10.12.1996; patent JP 1287371 , publ. 11/20/1989). Such technical solutions provide for the manufacture of only one type of prefabricated elements. To connect structural elements made in such forms, additional embedded and overhead parts are required. As a rule, welding or special adhesive compounds are used to connect them (Novikov V.U. Polymer materials: Handbook. - M.: Higher school, 1995. - P.338 ... 381). The use of welding leads to local heating of concrete and its destruction. The use of adhesives is not always possible in building conditions (low ambient temperature, precipitation, prolonged hardening of the adhesive or its low viability, etc.). The manufacture of prefabricated elements in such reinforcing-molding blocks is associated with high labor input and cost.

The closest in technical essence and the achieved effect is a reinforcing-molding block (patent JP 1014421, publ. 01/18/1989), comprising a housing with annular lower and upper supporting diaphragms, a lower cover covering the hole in the lower supporting diaphragm of the mold over its entire area , an upper lid covering the hole in the upper supporting diaphragm of the mold, covering and fixing the receiver of the loading device and consisting of a stop and a clamping ring fixing it with a thread on its outer surface, a reinforcing cage c, consisting of longitudinal and transverse reinforcement, its clamps, lower and upper butt rings containing connecting and anchor parts, while on the connecting parts there is a thread for joining adjacent prefabricated elements, and on anchor there are anchors for pairing butt rings with concrete, loading a device consisting of a receiver protruding above the upper supporting diaphragm of the form, and a distributor connected to it, which is fixed by a latch.

The disadvantages of the prototype are the following:

The prototype provides the ability to produce elements of only one type and size with a fixed arrangement of reinforcement.

Butt rings are located on the outer surface of the manufactured precast element. The consequence of this is a high consumption of material and low durability of the parts of the joints during operation of structures of such prefabricated elements in an aggressive environment.

The lower and upper supporting diaphragms of the form are made not removable, but left as embedded parts of the precast element. This determines the high material consumption of the junction of prefabricated elements.

The cavity of the upper butt ring is open and concrete mix gets into it when it is placed in the reinforcing-molding block. A hole is made in the center of the upper flange of the mold, the diameter of which is larger than the external size of the loading device. The place of its passage through the upper supporting diaphragm is not tight. Therefore, when filling the mold, the concrete mixture is poured and partially or completely fills the cavity of the upper butt ring, contaminating the thread. It is also possible accidental contamination of the concrete mixture and the external thread of the lower butt ring. Before joining the prefabricated elements, it is necessary to clean the cavity of the upper butt ring and its thread from the influx of concrete. The consequence is the high complexity of manufacturing a precast element. The loading device consists of a receiver and distributor protruding above the upper flange. It is made not by inventory, but left in the precast element. This increases the material consumption of the manufacture of the precast element.

The distributor of the loading device is made in the form of a pipe with solid walls. The consequence is an increase in hydraulic resistance to movement of the concrete mixture through the pipe and in the space between its outer surface and the inner surface of the mold when filling out the mold. To overcome hydraulic resistance, it is necessary to use a concrete pump, plasticizing additive, a special method of concreting, etc. This leads to an increase in the complexity and cost of manufacturing the precast element.

Filling the mold with concrete mixture is provided to the level of the lower edge of the stops of the upper cover. This arrangement of the stops leads to the formation of irregularities on the surface of the concrete and the need to process the upper face of the precast element, for example, to grout the concrete mixture. This increases the complexity of manufacturing the precast element.

When filling the mold with concrete mixture under the upper supporting diaphragm of the mold with stops and the clamping ring of the upper cover, air cavities are formed, which reduces the quality of the precast element.

The coupling of the stop and the clamping ring of the upper cover with the inner surface of the upper butt ring is not tight. There is a gap between the upper supporting diaphragm of the form and the lower edge of the clamping ring of the upper cover. Its height is determined by the height of the stop of the top cover. The concrete mixture fills the gap and freely penetrates the internal thread of the upper butt ring. Subsequently, the cement milk penetrates into the place where the pressure ring is mated to the internal thread of the upper butt ring. Therefore, the disassembly of the clamping ring and the stop after the manufacture of the prefabricated element is associated with significant labor costs, since it is necessary to apply significant mechanical stress. This reduces the turnover of the elements of the upper cover. The consequence is the low quality of the prefabricated element, significant labor costs for its manufacture, high material consumption due to the low turnover of the reinforcing-molding block and the rapid wear of the dismantled elements of the top cover.

After forming the prefabricated element, to connect it with the adjacent one, it is necessary to remove the concrete mixture or concrete from the upper butt ring and clean the internal thread of the upper and the external thread of the lower butt rings. This leads to additional labor costs for the manufacture of prefabricated element.

The objective of the invention is:

an increase in the number of types and sizes of prefabricated elements manufactured in a reinforcing-molding block of one standard size, a decrease in the material consumption of the joint for joining prefabricated elements, a decrease in the material consumption of the reinforcing-molding block, a decrease in the labor input of the assembly of the reinforcing-molding block, an increase in the turnover of the reinforcing-molding block, an increase in the effectiveness of the anti-corrosion block protecting parts of joints of prefabricated elements, improving quality and reducing the complexity of manufacturing prefabricated elements.

When assembling the upper cover, combine the contacting protrusions 141 and 142 in the upper face of the cover 66 of the gate 52 and the lower edge of the ring retainer 53, the contacting protrusions 143 and 144 of the wall 63 of the gate 52 and the upper face of the sleeve 49, the contacting protrusions 145 and 46 of the upper face of the flange 46 and the lower facets of sleeve 49.

The groove 57 for accommodating the lower sealing element 58 may be made of variable cross-section, as shown in Fig.26. Moreover, it has an inclined lower 147 flange 46 and the upper 148 of the thrust ring 47 of the face. They have an angle of inclination to the horizon, respectively φ ₃ and φ ₄ . The height of the groove increases from its outer part to the inner. With such a variable height of the groove and the sealing element 58, the nature of the work of its material and the quality of the sealing significantly change compared to when φ ₃ and φ ₄ are equal to zero. When φ ₃ and φ _{4 are} equal to zero, the mating of the interface of the upper joint ring and flange 46 of the upper cover 6, as well as the protection of the threads on the outer surface of the connecting part 76 of the upper joint ring 14 from penetration of cement milk from the mold body 1, is carried out with the vertical deformation of the sealing element 58 due to its transverse deformations. Moreover, the sealing quality is higher, the greater the cross-sectional height of the sealing element 58 and the Poisson's ratio for the material from which it is made. When φ ₃ and φ _{4 are} greater than zero, the sealing is also carried out due to the horizontal movement of the sealing element 58 from the groove. Therefore, the quality of the seal will be higher. To reduce wear and increase the durability of the sealing element 58, increasing its longitudinal deformations, it is necessary that tgφ ₃ and tgφ ₄ exceed the coefficient of friction of the sealing element on the material of the flange 46 and the thrust ring 47.

To increase the turnover of the upper cover 6 during its assembly, the gap 72 between the upper edge of the flange 46 and the lower edge of the sleeve 49, as well as the gap 73 between the upper edge of the sleeve 49 and the lower edge of the cover 66 of the gate 52, fill in accordance with claim 13 with a sealing material (gasket, non-hardening mastic). Filling should be carried out under the condition of the lower sealing element 58 that is free of interference. Such filling will prevent the penetration of cement milk, mortar concrete into the gaps 72 and 73, reduce wear and increase the durability of the upper cover, and reduce labor costs for its preparation for assembly of the reinforcing and molding block .

Assemble the reinforcement cage. When assembling the reinforcing cage according to claim 1, to connect the working reinforcement 11 with the anchor 75 part of the lower butt ring 13 and the anchor 77 part of the upper butt ring 14. Connect the transverse reinforcement 12 to the working reinforcement 11. Such connections can be made, for example, by welding.

When assembling the frame of the reinforcing-molding block according to claim 8, the connecting part 79 of the upper joint ring 14 has a length greater than the length of the connecting part 74 of the lower joint ring 13 by the height of the insert 111 between the prefabricated elements, as shown in Fig. 14. Insert 111 is provided to increase the number of types of prefabricated elements made in the form of one size.

When assembling the frame of the reinforcing-molding block according to claim 9, with anchors on the lower and upper butt rings, as shown in Fig. 15, connect the working reinforcement 12 with anchors 115. In the manufacture of the lower 13 and upper 14 butt rings, the length and width of the anchors 114 and 115 are determined from the condition of connecting the anchor parts of the upper and lower butt rings with longitudinal reinforcement, for example, parameters (length, leg) of the weld, cooling conditions of the weld overlay areas. The openings 112 and 113, arranged in the anchor parts 75 and 77, respectively, in the lower 13 and upper 14 butt rings, form the anchors 114 and 115. Moreover, the openings 112 and 113 themselves are elements that ensure the distribution of concrete mix when it is laid in the reinforcing-molding block. Therefore, their sizes are determined by the viscosity of the concrete mixture, the size of the aggregate.

When assembling the frame of the reinforcing-molding block according to claim 10, for example, when welding, as shown in Fig. 16, the collar 116 is connected with the lower butt ring 13, the collar 117 with the upper butt ring 14. Then connect, for example, by welding working armature 11 with lower 13 and upper 14 butt rings. The area and shape of the collars is set according to the permissible contact pressure between the precast elements, the required thickness of the concrete protective layer from the side of the lateral face of the precast element. The distance from the collars 116 and 117, respectively, to the lower and upper faces of the precast element is determined by the required thickness of the protective layer 120 and 121 of concrete, the viscosity of the concrete mixture and the size of the aggregate. To increase the reliability of the connection of the protective layer 120 and 121 of concrete and the quality of distribution of the concrete mixture in the collars 116 and 117, openings 122 and 123 are provided. Their size is determined by the size of the aggregate and viscosity. In order to reduce concrete cracking of the protective layers 120 and 121 and improve their working conditions when installing prefabricated elements and operating structures made from such prefabricated elements, they can be reinforced, for example, with a mesh.

When assembling the frame of the reinforcing-molding block according to claim 11 of the claims, after connecting the working 11 and transverse 12 reinforcement, lower 13 and upper 14 butt rings, install the core 124 in the space between the working reinforcement 12, as shown in Fig. 17. To fix its position using the clamps 125 and the upper axial rod 107 of the tarraver 20 of the lower cover 5 with a sealing element 110 (as shown in Fig.13). Such a hollow core can be either left in the concrete body, or recoverable, solid and hollow, for example, in the form of a pipe. The length of the core can vary depending on the type of construction. If the length of the void former is not less than the distance between the upper face of the tarover 20 of the lower cover 5 and the upper face of the upper butt ring 14, then it performs the function of a channel former, as shown in Fig. 18. That is, the prefabricated element is obtained with a through channel. The use of a pore former allows to reduce the consumption of concrete mixture, the mass of the precast element. The size and shape of its cross section is determined by the required reduction in the mass of the precast element, the thickness of the concrete protective layer, the size of the aggregate, and the viscosity of the concrete mixture. Materials can be used for the core former, for example plastic, with a high coefficient of thermal expansion. Heating due to the heat of exothermic reactions during heat-moisture treatment leads to an increase in the geometric dimensions of the core former. This leads to additional compaction of concrete, improving the quality of the precast element. During cooling, the cross-sectional size of the core former decreases, it can be removed and reused. Before its installation, a coating of a material (mastic, suspension, etc.) that diffuses into the concrete during its hardening and has a low adhesive bond with the surface of the core can be applied before its installation. This allows you to increase the density of concrete, its corrosion resistance, etc. The use of void formers with different parameters allows you to increase the number of sizes of prefabricated elements made in one form.

Assembly procedure for the reinforcing-molding block

The order of assembly is given for the reinforcing-molding block with a lower cover 5 according to claim 2.

Check the operation of the assembled lower cover 5 by turning the disk stop 22. When it is rotated clockwise (with right screw connections), the compression of the sealing element 36 decreases, increases counterclockwise. Turn the disk stop 22 to the position where the upper sealing element 36 will take a free state without interference. The bottom cover is prepared for assembly of the reinforcing-molding block.

Connect the bottom cover 5 to the reinforcement cage. To this end, by means of a thread 26 on the outer surface of the walls 25 and an internal thread 78 of the connecting part 74, connect the cup 17 of the flange 16 of the lower cover 5 with the lower joint ring 13 of the reinforcing cage. It should be connected until the lower edge of the joint ring 13 abuts against the upper face of the flange 16. This allows compression of the lower sealing element 30 in the groove 29 and sealing of the interface between the lower joint ring 13 and the flange 16. The thread 78 on the inner surface of the lower joint ring 13 and the thread 26 on the wall 25 of the glass 17 are protected from cement milk from the body 1 of the form.

Insert the free end of the reinforcing cage into the mold case 1 from the side of its lower flange 2 until the upper face of the flange 16 of the lower cover 5 and the lower face of the lower supporting diaphragm 2 of the form are mated. Then connect the lower cover 5 to the lower supporting diaphragm 2 of the form with the connecting elements 45.

Reducing the complexity of the connection of the lower cover 5 and the lower supporting diaphragm 2 of the form is ensured by the presence and alignment, as shown in Fig. 20, of centering elements made in the form of an annular groove 131 in the flange 16 of the lower cover 5 and the corresponding shape and size of the protruding annular ridge 132 in the lower supporting diaphragm 2 of the housing of the form 1.

Check the operation of the assembled top cover 6 by turning the gate 52. When it is rotated clockwise (with right-hand threaded connections), the compression of the lower sealing element 58 decreases, increases counterclockwise. Turn the collar 52 to the position where the lower sealing element 58 assumes a free state without interference. The top cover is prepared for assembly of the reinforcing-molding block.

Install the upper cover 6 on the upper face of the upper supporting diaphragm 3 of the mold, passing the connecting part 76 of the upper joint ring 14 through the hole 54 in the flange 46 of the upper cover. In this case, the lower face of the flange 46 of the upper cover 6 interacts with the upper face of the upper supporting diaphragm 3 of the mold and the outer surface of the connecting part 76 of the upper joint ring 14 is in contact with the lower 58 and upper 68 sealing elements. Connect the top cover 6 with the upper supporting diaphragm 3 of the form with the connecting elements 45.

The reduction in the complexity of the connection of the upper cover 6 and the upper supporting diaphragm 3 of the form is ensured by the presence and alignment, as shown in Fig. 21, of centering elements made in the form of an annular groove 133 in the upper supporting diaphragm 3 of the housing of the form 1 and the protruding annular corresponding to it in shape and size ridge 134 in the flange 46 of the upper cover 6.

Turn the disk stop 22 together with the rod link 23 of the lower cover counterclockwise until it stops. In this case, the axial annular rod 19 together with the thrust ring 18 moves up. The height of the groove 35 decreases and compression of the upper sealing element 36 occurs. The sealing element is made of a material (eg, rubber) with a high Poisson's ratio. There is a decrease in the height of its cross section and an increase in width. This is achieved by sealing the threaded connection of the connecting part 74 of the lower butt ring 13 and the walls 25 of the glass 17 of the flange 16 of the lower cover 5 from the penetration of cement milk from the mold body 1.

Turn the gate 52 of the top cover 6 counterclockwise until it stops. In this case, the pressure ring 51 moves downward, and the stop ring 47 moves with it. In this case, the height of the groove 57 decreases and the lower sealing element 58 is compressed. The sealing element is made of a material (for example, rubber) with a high Poisson's ratio. There is a decrease in the height of its cross section and an increase in width. This achieves sealing and protection against penetration of cement milk pairing of the flange 46 of the upper cover 6 and the thrust ring 47, as well as the thrust ring 47 and the outer surface of the connecting part 76 of the upper butt ring 14.

After performing these operations, the reinforcing-molding block is ready for laying concrete mixture. Laying is carried out through the connecting part 76 of the upper butt ring 14. The upper face of concrete in the upper butt ring 14 coincides with its upper face.

After hardening of concrete, the mold is disassembled, including the housing 1 with the lower 2 and upper 3 supporting diaphragms, the lower 5 and upper 6 covers.

The procedure for dismantling the reinforcing-molding block

To disassemble, do the following. Turn the gate 52 of the upper cover 6 clockwise until it stops. In this case, the clamping ring 51 moves up. Together with it, the thrust ring 47 moves, the height of the groove 57 increases. The compression of the lower sealing element 58 is eliminated and it is separated from the concrete surface. Then remove the connecting elements 45 and the top cover 6.

Turn the disk stop 22 of the lower cover 5 clockwise until it stops. When this happens, the axial annular rod 19 is moved down with the thrust ring 18, the height of the groove 35 increases. The compression of the upper sealing element 36 is eliminated and it is separated from the concrete surface. Remove the connecting elements 45 and the bottom cover 5.

Remove the centering elements 8 and connecting 9 in the ribs 4 of the housing 1 of the form. Separate the shell 7 from the surface of the reinforced concrete element.

The housing 1 with the lower 2 and upper 3 supporting diaphragms, the lower 5 and upper 6 covers are used to assemble the next formwork block. Working 11 and transverse 12 reinforcement, lower 13 and upper 14 butt rings remain in the body of the precast concrete element.

Achievable technical result

The technical result of using the proposed device is as follows.

The increase in the number of types and sizes of prefabricated elements manufactured in the reinforcing-molding block of one size is determined by the fact that the proposed device allows to produce both solid and hollow prefabricated elements with closed voids and through channels, with left and removed hollow formers and channel formers, with inserts between prefabricated elements. For their fixation, the upper edge of the tarera is equipped with an upper rod, on the outer surface of which a groove is made to accommodate the sealing element of the void forming device of the loading device. In the reinforcing cage, the length of the connecting part of the upper joint ring is greater than the length of the connecting part of the lower joint ring by the height of the insert between the prefabricated elements.

The reduction in the material consumption of the joint for connecting prefabricated elements is determined by the fact that the transverse size of the lower and upper butt rings is less than the transverse size of the manufactured prefabricated element

The reduction in material consumption of the reinforcing-molding block is determined by the fact that the mold body with the lower and upper supporting diaphragms, the lower and upper covers are made inventory (wrapped). They are repeatedly used for the assembly of reinforcing and formwork blocks. The function of the receiver of the loading device is performed by the connecting part of the upper butt ring, and the distributor uses the anchor parts of the upper and lower butt rings, longitudinal and transverse reinforcement, and the latch function is performed by the flange with the glass of the lower cover and the stop ring of the upper cover and therefore the need for such special elements absent.

Reducing the complexity of the assembly of the reinforcing-molding block is determined by the fact that the edges of the housing and its lower and upper supporting diaphragms, lower and upper covers (their flanges), lower and upper supporting diaphragms of the body and flanges of the covers are provided with centering and connecting elements. During assembly, centering and joining operations are performed sequentially and using different elements.

The increase in the turnover of the reinforcing-molding block is determined by the fact that the lower and upper covers, their interfaces with the lower and upper supporting diaphragms of the mold body are sealed, their elements are protected from the possibility of ingress of building mortar and cement milk, and therefore the possibility of mechanical damage during disassembly, cleaning is eliminated and assembly of the reinforcing-molding block.

The increase in the effectiveness of anticorrosive protection of joints of concrete and reinforced concrete structural elements and elements is determined by the fact that the outer surfaces of the butt rings and their collars are provided with a protective layer of concrete, and after the assembly of prefabricated elements, all parts of the joints of the assembled structure are protected from direct exposure to aggressive media.

Improving the quality of manufacture of structures and elements is determined by the fact that radial grooves are made on the upper face of the upper supporting diaphragm, openings are made in the anchor parts of the lower and upper butt rings and in the collars. These technical solutions ensure that the concrete mixture fills the entire internal space of the mold body and eliminates the possibility of air cavities. The flanges of the lower and upper covers completely overlap the lower and upper sections of the mold body, forming a flat surface over the entire area of the lower and upper sections of the prefabricated element. In this case, the interface between the flanges of the covers and the upper and lower butt rings are sealed with sealing elements, which prevents the formation of irregularities in these places. Anchors are formed on the anchor parts of the lower and upper butt rings, the presence of which allows to reduce temperature deformations when connecting reinforcement and butt rings when welding.

Reducing the complexity of manufacturing prefabricated elements is determined by the fact that the thread on the upper butt ring is made on its outer surface, and on the lower butt ring - on the inner surface, the upper and lower covers are sealed and therefore the thread of the butt rings, cover elements are protected from the possibility of building mortar and its components and therefore eliminated the need for cleaning. The distributor function is performed by the anchor parts of the upper and lower butt rings, longitudinal and transverse reinforcement, which leads to a decrease in hydraulic resistance during the movement of concrete mixture, the duration and complexity of laying concrete mixture
