Description

TECHNICAL FIELD

[0001] The present application relates to the field of building technology, and particularly to a prefabricated anti-kick-off piece and a production process thereof. BACKGROUND

[0002] Fabricated building belongs to the main trend of future development of building, the core of fabricated building is composed of various prefabricated parts, the existing fabricated prefabricated parts can not need to be decorated on the surface, mainly for stone, tile reverse hit prefabricated parts. The existing reverse hit process method is: 1. Stone reverse hit, the back of the stone plate with a certain thickness (the thickness of the stone is generally more than 25mm) is opened, and then the metal wire with a certain hardness is bent into the opposite anchor hook hanging in the hole, in order to prevent the anchor from shaking, chemical glue is generally used to fix, the prepared reverse stone is laid in the formwork and the plate joint is sealed, and then the steel reinforcement is laid and the concrete is poured to form reinforced concrete, the forming principle is: the reinforced concrete will bite the anchor hook of the stone plate hook, so as to get the fabricated prefabricated part with stone decoration surface; 2. Tile reverse hit, the tile with tenon groove on the back is laid in the mold, and the brick joint is sealed, then the steel reinforcement is laid and the concrete is poured, the forming principle is: the reinforced concrete will bite the tenon groove on the back of the tile, so as to get the fabricated prefabricated part with tile decoration surface. The existing stone and tile reverse hit prefabricated parts have the following problems: 1. Not environmentally friendly, stone mining and processing, tile high temperature firing all belong to non-environmental protection products; 2. Poor safety, thick stone opening hole can only use metal wire hook anchor, which has the problems of low hanging strength and chemical glue reinforcement easy to age and degrade, so the anti-seismic performance is poor and easy to produce the serious safety hazard of falling off; The tile completely depends on the bite force generated by the back tenon groove and the concrete to fix, there are many gaps between the outdoor wall tiles, which will be eroded and damaged by rain, snow, ultraviolet rays and other harmful substances, so it is inevitable to cause the concrete to effloresce and age, so that the concrete loses the bite force, at the same time, the tile and the concrete will produce different degrees of expansion and contraction due to temperature difference, and more cracks will be produced, the superposition of these factors will cause the tile to loosen and fall off, thus causing serious safety hazard; 3. Low production efficiency, it is more difficult to implement multi-surface and multi-angle reverse hit and multi-surface and multi-angle heat preservation and sound insulation. The existing stone plate and tile implement reverse hit with heat preservation and sound insulation, the stone plate and tile are laid on the bottom of the formwork, then a layer of concrete structure is poured, and the concrete must be cured, and after the stone plate or tile is bitten, the heat preservation material can be laid on the solidified concrete surface, and the next step of concrete structure pouring can be carried out, therefore, it is necessary to pour and cure many times to form the reverse hit prefabricated part with heat preservation and sound insulation function, which not only has low production efficiency, but also is affected by the structural defects of stone and tile, so only the prefabricated part with simple structure can be reverse hit, and the multi-surface and multi-angle reverse hit and multi-surface and multi-angle heat preservation and sound insulation of the prefabricated part such as column, beam and window are more difficult to implement; 4. The existing prefabricated part cannot realize the decoration of the surface, and can only be decorated with paint, tile and stone after assembly, but these materials cannot meet the basic standard of green building materials, and some even completely violate the concept of green building materials, at the same time, the implementation of heat preservation and sound insulation has the problems of great installation difficulty and poor safety. SUMMARY

[0003] The present application aims to provide an assembled anti-kick prefabricated part and a production process thereof to solve the problems in the background art.

[0004] The technical solution adopted by the present application is as follows:

After curing and thickness setting, the cement-based artificial stone plate is formed. The front surface of the cement-based artificial stone plate forms a finish layer through one of the following methods: stripping, printing, sticking, and wrapping. A nut is embedded in the back of the cement-based artificial stone plate. The nut is threadedly connected with one end of an anchoring connecting rod. The anchoring part is an arbitrary geometric shape larger than the cross-sectional area of the anchoring connecting rod. A protective film is coated on the outer surface of the cement-based artificial stone plate as needed.

[0007] ② Mould preparation: multiple cement-based artificial stone plates are laid flat in the mould to form the required size, and the plate joints between the plates are sealed and treated.

[0008] S2. Anti-kick preparation

[0009] ① A metal framework is laid in the mould in which the cement-based artificial stone plates are laid, and then a threaded sleeve is arranged on the side of the metal framework.

[0010] ② When pouring the concrete, it is vibrated and leveled as needed, and then it is cured to form reinforced concrete.

[0011] ③ The anchoring connecting rod body is located in the reinforced concrete. The anchoring connecting rod body located in the reinforced concrete is provided with an anchoring part. The anchoring part is an arbitrary geometric shape larger than the cross-sectional area of the anchoring connecting rod. After the poured reinforced concrete structure is completely solidified, the resulting maximum structural force will engage the anchoring connecting rod and its anchoring part, thereby completely fixing the cement-based artificial stone plate and the reinforced concrete into an interconnected whole, thereby obtaining an assembled anti-kick prefabricated part.

[0012] As a preferred option, in the step ① of the S1 preparation, when the cement-based artificial stone plate is a super high performance artificial stone plate, the raw materials of the artificial stone plate are configured according to the super high performance standard. The plate preparation technology increases strong pressure and vacuum extraction as the main technical means in addition to the basic technical means of vibration.

[0013] As a preferred option, in the step ① of the S1 preparation, a mesh is arranged in the cement-based artificial stone plate.

[0014] As preferred, in the step ① of the S1 preparation, the anchoring connecting rod is provided with a layer of thermal insulation material or a layer of sound insulation material or a composite layer of thermal insulation material and sound insulation material.

[0015] As preferred, in the step ① of the S2 reverse striking preparation, a device for forming a through structure hole with a hard pipe or a soft rod or a threaded connecting grouting sleeve can be provided in the metal framework as needed.

[0016] As preferred, in the step ② of the S2 reverse striking preparation, before pouring the concrete, the end of the anchoring connecting rod is threaded connected with the embedded nut, and then the concrete is poured and the reinforced concrete is formed after curing, and the screw port of the embedded nut is exposed at the back of the reinforced concrete.

[0017] As preferred, in the step ② of the S2 reverse striking preparation, a plurality of embedded nuts are implanted before pouring the concrete or before the initial setting of the concrete.

[0018] As preferred, the embedded nut is a double-threaded nut or a winged nut, and the screw port of the embedded nut is not higher than the back of the reinforced concrete.

[0019] As preferred, in the step ② of the S2 reverse striking preparation, when pouring the concrete, the laid metal framework is exposed as needed, and the reinforced concrete is formed after curing.

[0020] As preferred, in the step ② of the S2 reverse striking preparation, when pouring the concrete, a space with the thickness of the cement-based artificial stone plate is reserved, and then the prepared cement-based artificial stone plate in the step ① of the S1 preparation is directly laid or back screw connected or directly laid with a decorative suction cup.

[0021] As preferred, in the step ③ of the S2 reverse striking preparation, the anchoring part and the anchoring connecting rod are an integral structure.

[0022] The cement-based artificial stone plate for prefabricated decoration of the present application is made of cement-based material as the main material, can adopt the highest standard of ultra-high performance in the field of concrete as the preparation standard, through the plate making method of vibration, strong pressure and vacuum extraction, can make the plate strength higher and the compactness better, and implant stainless steel mesh and nut which can be connected externally during the plate making, after the plate is made, the surface adopts the same stripping principle of natural stone material, can form various finishing effects of natural stone material, therefore, the artificial stone plate can completely achieve the service life of more than 100 years of natural stone material. When the artificial stone plate is used as the base plate, the surface can realize any finishing effect of any material through wrapping, pasting, painting and other processing methods. The excellent performance of the ultra-high performance cement-based artificial stone plate itself can achieve the highest fireproof, waterproof and corrosion resistant standards, can effectively prevent efflorescence and water seepage. Therefore, the ultra-high performance cement-based artificial stone plate can completely replace the existing stone material and ceramic tile as the finishing surface of the prefabricated assembly, and can realize more rich finishing effects. Moreover, it can be used more healthily and last longer than the existing decorative materials such as paint, ceramic tile, stone material and wood, and can also completely solve the environmental unfriendliness and various performance defects of these materials.

[0023] The ultra-high performance cement-based artificial stone plate made of ultra-high performance standard, combined with the whole plate interconnection of stainless steel mesh in the plate, not only can make large size thin plate, but also can ensure that the ultra-high performance cement-based artificial stone plate has extremely high bending, tensile and impact resistance, so as to completely withstand the impact and destructive force generated during pouring concrete. The nut completely integrated with the artificial stone plate can have extremely strong screw mounting force, so as to completely solve the problems of heavy weight, low mounting strength, and easy aging of chemical glue in the stone back hitting which can only use thick plate to connect anchor; and the problems of low connection strength, easy water seepage and alkali efflorescence in the ceramic tile back hitting which can only rely on the specially designed mortise in the back and completely depend on the concrete bite, resulting in the major safety hazards of easy loosening and falling. The anchor connecting rod screwed in the back of the artificial stone plate can clamp any material of thermal insulation and sound insulation material in the back of the plate, which is a function that the existing stone and ceramic tile back hitting cannot achieve. We also set the anchor part with any geometric shape larger than the cross-sectional area of the anchor connecting rod at the end of the anchor connecting rod. When making single-sided back hitting prefabricated parts, we lay it in the mold of the prefabricated part, directly lay the metal skeleton and pour concrete, and the set concrete will completely wrap the anchor part at the end of the anchor connecting rod. The strong wrapping force of reinforced concrete structure and the setting of the anchor part larger than the anchor connecting rod can generate a large connection force of the anchor connecting rod, so that the plate completely interconnected with the anchor connecting rod will be interconnected with the concrete structure to form a whole, so that the single-sided back hitting of the prefabricated part can easily realize the functions of thermal insulation, sound insulation and decoration, and has extremely high safety. According to the above principle, when making prefabricated parts such as beams, columns and windows that need multi-sided decoration, the plate clamping thermal and sound insulation materials can be directly laid on the bottom and sides of the mold or screwed and connected through long steel bars combined with anchor connecting rods, so that multi-sided back hitting decoration and multi-sided thermal and sound insulation functions can be easily achieved. In the pouring surface of the prefabricated part, it is extremely difficult for the existing stone and ceramic tile to implement decoration. After clamping thermal and sound insulation materials through anchor connecting rods, the ultra-high performance cement-based artificial stone plate can be directly laid on the surface of the poured concrete by direct laying, back screwing and connecting or using a decorative suction cup. After the concrete is set, it will completely bite the anchor connecting rod extending in the reinforced concrete and having a larger diameter anchor part, so that we can achieve the functions of all-around decoration and thermal and sound insulation of the prefabricated part. The strong mounting force generated by the screwing advantage of the artificial stone plate back, the strong connection force generated by the setting of the anchor connecting rod end larger than its cross section, and the easy realization of thermal and sound insulation function by physical clamping, these advantages cannot be achieved by the existing stone punching and ceramic tile setting mortise.

[0024] Meanwhile, we use anchor connecting rod screwing connection double-pass nut, so that the screw hole of the nut is located at the back of the reinforced concrete, or the wing-shaped nut is implanted after the concrete pouring, or the concrete is poured after connecting with the metal framework. After the prefabricated part is made, the embedded nut becomes a whole with the entire prefabricated part, and can be easily and flexibly screwed with various connecting parts, which not only solves the installation problem of the back-pounding prefabricated part, but also clamps various thermal and sound insulation materials to easily realize the thermal and sound insulation and bidirectional decoration function. When used as a prefabricated part, the embedded nut at the back of the back-pounding prefabricated part can be connected or fixed on the metal framework or located inside or outside the framework through screwing various connecting parts and passing through thermal and sound insulation materials. After pouring concrete to wrap and solidify the connecting parts in the embedded nut, a structural wall body can be directly formed, thereby replacing the existing whole prefabricated wall and double-sided composite wall panel, and solving the problems of large weight, difficult installation, and the necessity of decoration, thermal insulation, and sound insulation construction of these prefabricated parts. The existing composite panel can be replaced to form a floor slab, which can directly save the later decoration, thermal insulation, and sound insulation construction. When replacing the existing steel, aluminum, and wood formwork, the reinforced concrete structure of the back-pounding prefabricated part can completely bear the expansion force generated during the pouring of concrete. The connecting parts screwed by the embedded nut at the back of the prefabricated part are wrapped by the poured concrete, which can make the cast-in-place building directly become a finished building with decoration, thermal insulation, and sound insulation functions. By screwing various metal connecting parts at the back of the back-pounding prefabricated part, various integrated house structures with wall and roof can be directly assembled. When used as a frame structure enclosure system, the embedded nut of the back-pounding prefabricated part is directly locked on the frame formed by steel structure, reinforced concrete structure, wood structure, etc. after screwing various connecting parts, which can directly become the wall and roof enclosure system of these structures. Not only does it directly realize the functions of structure, decoration, thermal insulation, and sound insulation, but also solves the problems of existing enclosure system metal oxidation and corrosion, environmental pollution, low strength and poor performance of various lightweight block wall panels, and various defects of various decoration, thermal insulation, and sound insulation construction. The excellent performance of the back-pounding prefabricated part and the advantages of screwing connection can also be used in various military barracks, box transformers, and sentry boxes, and can withstand various harsh environments.

[0025] The present application can adopt the highest technical standard configuration of cement concrete to configure the super high performance artificial stone plate, after adopting the existing manufacturing super high performance concrete difficult to implement the vibration, strong pressure, vacuum plate making method, the cement based artificial stone plate can completely reach the performance limit of the existing cement concrete. After the cement based artificial stone plate is decorated, it can become a whole with the reinforced concrete structure formed by the cement base, and can reach the lowest C100 above artificial stone plate, and after being used as the overall surface layer of the existing C30, C40 reinforced concrete prefabricated structure, it can completely block the ultraviolet rays, rainwater and other harmful substances from causing various erosion and damage to the reinforced concrete structure. Therefore, the building assembled by the prefabricated parts protected by the super high performance cement based artificial stone plate can greatly improve the service life compared with the existing assembled building protected by the ceramic tile, paint and other decorative materials.

[0026] The super high performance cement based artificial stone plate of the present application is mainly made of waste natural stone processing waste or widely existing miscellaneous stones and gravel which can even affect crop growth, and uses industrial waste such as silica ash, mineral powder and fly ash as cementitious materials. The production does not need high temperature firing, does not produce chemical odor, and the waste generated during processing can be reused or made into other building materials, so it can completely reach the highest environmental protection standard of zero pollution and zero emission. The super high performance cement based artificial stone plate without any harmful substances can meet the highest health requirements during use, and after adding nano or surface nano treatment, it can also realize sterilization, self-cleaning, air purification and other beneficial functions. The super high strength and super high durability can also exceed the high strength and high durability standards of the highest requirements of green building materials. After the plate is removed, it can be processed into a new decorative panel, or it can be crushed and processed into a new product, so all links can meet the highest standard of green building materials. The present application uses super high performance cement based artificial stone plate to replace stone and ceramic tile to make prefabricated parts, and the building assembled after the prefabricated parts can directly realize high efficiency and energy saving green building. Therefore, the present application is an innovative technology that benefits the country and the people. BRIEF DESCRIPTION OF DRAWINGS

[0053] Embodiment 1

[0054] By Figure 1 It can be known that the prefabricated part is a single-face reverse hitting prefabricated part.

[0055] S1. Preparation

[0056] ①Panel preparation: the cement-based artificial stone panel 1 is prepared by taking cement and aggregate as main raw materials and taking vibration as basic panel preparation technical means. After curing and thickness setting, the cement-based artificial stone panel 1 is formed.

The outer surface of the panel 1 can be covered with a protective film for future use according to needs;

[0057] ② Mould preparation: Prepare the mould with the required size, lay several cement-based artificial stone slabs 1 on the bottom, and seal the joints between the slabs.

[0058] S2. Backshot production

[0059] ① Lay the metal framework 7 in the mould in which the cement-based artificial stone slabs 1 are laid, and set threaded sleeves 10 on the sides of the metal framework 7;

[0060] ② When pouring the concrete, vibrate and level it as required, and form the reinforced concrete 8 after curing;

[0061] ③ The anchoring connecting rod 4 body is located in the reinforced concrete 8, and the anchoring connecting rod 4 body located in the reinforced concrete is provided with an anchoring part 9, which is an arbitrary geometric shape larger than the cross-sectional area of the anchoring connecting rod 4, and the anchoring part 9 can be an integral structure with the anchoring connecting rod 4; after the poured reinforced concrete structure is completely cured, the extremely large structure force formed thereby will engage the anchoring connecting rod 4, thereby completely fixing the cement-based artificial stone slabs 1 and the reinforced concrete 8 into an interconnected whole, thereby obtaining the prefabricated piece of the assembled single-face backshot;

[0062] ④ The prefabricated piece of the assembled single-face backshot can be a prefabricated piece of the assembled single-face backshot floor slab, composite slab, or wall slab, etc.

[0065] Example 2

[0066] As shown in Figure 2As can be seen, unlike Example 1, in the preparation of the slab, the cement-based artificial stone slab 1 is an ultra-high performance cement-based artificial stone slab. The ultra-high performance cement-based artificial stone slab is made of cement and aggregate as the main raw materials, configured according to ultra-high performance standards. Its slab-making technology adds strong pressure and vacuum as the main technical means to the basic technical means of vibration. After curing and thickness determination, the ultra-high performance cement-based artificial stone slab is formed.

[0069] Depend on Figure 6 As can be seen, when the precast component is used as a finished floor slab, it is transported to the construction site and laid on the top of the full-span scaffold by hoisting. The exposed part of its metal frame can be used to insert steel bars, which can be tied to the steel frame of the shear wall or the steel frame of the beam and column. It can also be connected to the upper part of the frame structure through metal connection devices 13 of the shape of screw corner or straight bar. Finally, grouting is used to fix it, thus obtaining a multi-functional floor slab structure.

[0070] Example 4

[0079] ④As can be seen from Figure 9 , when the prefabricated part is used as a wall panel with a decorative surface, it is transported to the construction site and hoisted on the building structure, the threaded hole of the embedded nut 11 on the back of the wall panel with a decorative surface is threadedly connected with the threaded end of the metal connecting device 13, the main body of the connecting device 13 is fixedly connected with the upper, middle and lower parts of the frame structure 16, and the connecting device 13 is a threaded connecting rod with one end, which can be threadedly connected with square steel, channel steel 17, etc., so as to be applied to the building frame structure. A layer of thermal insulation material 5 or a layer of sound insulation material 6 or a composite material layer composed of the thermal insulation material layer 5 and the sound insulation material layer 6 can be arranged between the wall panel with a decorative surface and the frame structure 16; and foamed cement or the like can be filled in the cavity therebetween.

[0081] Example 5

[0082] As can be seen from Figure 8 , the difference from example 4 is that in the preparation of the slab, the anchoring connecting rod 4 is provided with a layer of thermal insulation material 5 or a layer of sound insulation material 6 or a composite material layer composed of the thermal insulation material layer 5 and the sound insulation material layer 6.

[0083] As can be seen from Figure 11It can be seen that when the multifunctional single-sided assembled back-connection precast piece is applied to the shear wall, the screw hole of the embedded nut 11 on the back of the precast piece can be screwed and connected with the threaded end of the connecting piece 13, and the connecting piece 13 is provided with an arbitrary geometric shape larger than the cross-sectional area of the end portion; or the threaded end of the connecting piece 13 is screwed and connected after the precast pieces are respectively hoisted on the side of the steel reinforcement framework at the construction site, the connecting piece 13 is provided with a layer of thermal insulation material 5 or a layer of sound insulation material 6 or a composite material layer composed of the thermal insulation material layer 5 and the sound insulation material layer 6, and then a triangular support frame is arranged on the outside of the precast piece for reinforcement to prevent tilting; a corner connecting piece can also be arranged at the bottom end of the precast piece for reinforcement, and finally the reinforced concrete is poured between the two opposite wall panels with a decorative surface, the main body of the connecting piece 13 is located in the reinforced concrete, and the hardened reinforced concrete is engaged with the two precast pieces and the connecting piece 13, thereby obtaining a shear wall or wall cast-in-place structure with decoration, thermal insulation and sound insulation functions, or obtaining a cast-in-place shear wall that replaces the formwork and eliminates the need for decoration, thermal insulation and sound insulation.

[0084] Example 6

[0085] By Figure 12 It can be seen that when the precast piece is a single-sided back-connection precast piece, the cement-based artificial stone panel 1 is an ultra-high performance cement-based artificial stone panel, and the embedded nut 11 is a double-pass nut or a nut with wings.

[0086] S1. Preparation

[0087] ① Panel preparation: The ultra-high performance cement-based artificial stone panel is prepared by using cement and aggregate as main raw materials and configuring according to the ultra-high performance standard. The panel preparation technology increases strong pressure and vacuum extraction as the main technical means based on the basic technical means of vibration. After curing and thickness setting, the ultra-high performance cement-based artificial stone panel is formed. The front surface of the ultra-high performance cement-based artificial stone panel forms a decorative layer through one of the following methods: stripping, printing, sticking, and wrapping.
