Description

Technical Field

[0001] The invention relates to the field of casting molds, and in particular to a PC component casting mold platform and an installation method thereof. Background Art

[0002] PC components are prefabricated concrete parts, specifically concrete products that are processed and produced in a standardized and mechanized manner in a factory. In contrast, traditional cast-in-place concrete requires on-site molding, on-site pouring, and on-site maintenance. Prefabricated concrete parts are widely used in construction, transportation, water conservancy and other fields, and play an important role in the national economy. Existing PC components are mostly produced using rotating or mobile equipment, and require the assistance of supporting steam rooms for maintenance. The overall cost is high, and various supporting facilities are in great demand. The area occupied is large, and the movement and transportation are limited. They can only be used in qualified urban areas, and cannot be adapted to areas with poor basic conditions. At the same time, they cannot be transported as a whole over long distances. Summary of the invention

[0003] The first purpose of the present invention is to provide a PC component casting mold platform, which has low cost, is easy to transport, hoist, transfer and build, and can be spliced ​​and built with bottom molds of different sizes according to different construction sites and needs, with high flexibility.

[0007] Furthermore, the long side of the bottom mold single plate is 6 meters and the wide side is 2 meters.

[0008] Further, the planes where the transverse plate and the longitudinal plate are located are both perpendicular to the plane where the bottom die single plate is located. The longitudinal plate is arranged parallel to the long side of the bottom die single plate. The U-shaped area between the outer side of the longitudinal plate and the upper clamping plate and the lower clamping plate is one of the rectangular edge grooves. A plurality of lifting lugs are evenly arranged in the rectangular edge groove. The lifting lugs are provided with lifting holes, and the plurality of lifting lugs on both sides of the bottom die single plate are symmetrically arranged.

[0009] Further, the support platform includes a cement seat in the shape of a trapezoidal platform and a metal plate laid on the top surface of the cement seat. The bottom die single plate is erected on the metal plate. A cement coating is laid in the rectangular edge groove above the support platform, and the cement coating is connected to the corresponding cement seat.

[0010] Further, a plurality of support platforms included in each row of the support platforms are all located directly below the two sides in the width direction of the bottom die single plate, and a plurality of support platforms included in each column of the support platforms are all located directly below the long side of the bottom die single plate.

[0011] Further, a plurality of support platforms included in each column of the support platforms are located directly below a plurality of the lifting lugs and are connected to the rectangular edge groove and the lifting lugs through the cement coating.

[0012] Further, a plurality of groups of side molds are arranged in an array on the top surface of the bottom die, and each group of side molds encloses a rectangular pouring area.

[0013] Further, an air supply pipeline is laid at the edge of the bottom die. The air supply pipeline is connected with a plurality of air outlet pipes. Each air outlet pipe is located between two adjacent groups of side molds, and a tarpaulin is hermetically covered outside the bottom die.

[0014] An installation method of the above PC component pouring die table includes the following steps:

[0015] S1. Prepare a plurality of support platforms arranged in an array and level them. The distance between each column of the support platforms is the same as the width of the bottom die single plate, and the distance between each row of the support platforms is 1 / n of the length of the bottom die single plate, where n is an integer greater than or equal to 3;

[0016] S2. Hoist and place a plurality of bottom die single plates on the support platforms in sequence, and the edges of adjacent bottom die single plates are joined to form a rectangular bottom die;

[0017] S3. Lay a cement coating in the rectangular edge groove above the support platform and connect the cement coating to the corresponding support platform;

[0018] S4. Fix the side mold on the top surface of the bottom die to form a pouring area.

[0019] The beneficial effects of a PC component pouring die table provided by the present invention are:

[0020] (1) By setting a plurality of bottom formwork single plates, the bottom formwork as a whole is divided into blocks, which is convenient for transportation, hoisting, transfer and construction on the one hand, and can also be spliced ​​and constructed into bottom formworks of different sizes according to different construction environments and requirements on the other hand, which is highly flexible; further, by setting a bottom formwork single plate including an upper clamping plate and a lower clamping plate, and sandwiching a supporting assembly between the two, a multi-layer sandwich method is adopted to reduce the weight and strengthen the structural performance of the bottom formwork single plate. Specifically, the supporting assembly includes two horizontal plates and two vertical plates, and the two horizontal plates and the two vertical plates are connected in a tic-tac-toe shape. The two horizontal plates are connected in a tic-tac-toe shape. The plate and the two longitudinal plates are arranged to form a rectangular middle cavity, thereby forming a hollow grid-like sandwich structure, which effectively reduces weight while improving structural performance; by setting the length and width of the rectangular middle cavity to be smaller than the length and width of the bottom mold single plate, four rectangular side grooves are formed between the outer sides of the two transverse plates and the two longitudinal plates and the upper and lower splints. On the one hand, the rectangular side grooves can be equipped with reinforcing ribs to further improve the structural strength, and structures that are convenient for lifting can also be added therein. The above-mentioned reinforcing ribs or lifting structures can be hidden in the rectangular side grooves without affecting the overall splicing of the bottom mold.

[0021] (2) A number of support platforms are arranged in an array, and the distance between each row of support platforms is the same as the width of the bottom mold plate. The distance between each row of support platforms is 1 / n of the length of the bottom mold plate, where n is an integer greater than or equal to 3. This ensures the supporting performance while facilitating the transportation and installation of the bottom mold plate, and also facilitates the disassembly of the bottom mold plate. Specifically, the distance between each row of support platforms is the same as the width of the bottom mold plate. When erecting, the two sides of the bottom mold plate in the width direction are respectively erected on two adjacent support platforms in each row to prevent the middle part of the bottom surface of the bottom mold plate from bearing the supporting force. At the same time, the support assembly can also prevent the middle part from bending. By setting the distance between each row of support platforms to 1 / n of the length of the bottom mold plate, where n is an integer greater than or equal to 3, a row of support platforms is evenly arranged directly below the two sides of the bottom mold plate in the width direction and evenly distributed along the long sides when erecting, providing stable supporting performance.

[0022] (3) By setting the planes of the transverse plate and the longitudinal plate to be perpendicular to the plane of the bottom mold single plate, a number of right-angle structures are formed between the upper and lower splints and the transverse and longitudinal plates, thereby effectively improving the structural performance of the bottom mold single plate. By setting the longitudinal plate to be parallel to the long side of the bottom mold single plate and the transverse plate to be parallel to the short side of the bottom mold single plate, four rectangular side grooves are formed to ensure that the cross-section of the rectangular side groove remains rectangular. By setting a number of lifting ears in the rectangular side groove and opening lifting holes on the lifting ears, the lifting ears on both sides of the bottom mold single plate are symmetrical, which is convenient for lifting and balancing. Since the lifting ears are hidden in the rectangular side grooves, they will not hinder the splicing of the bottom mold single plates, thereby effectively avoiding the generation of gaps.

[0023] (4) By providing a support platform including a cement seat, and providing the cement seat in a trapezoidal platform shape, the cement seat has better support performance and prevents the cement seat from deformation and collapse. By providing a metal plate, the smooth top surface of the metal plate is used to replace the rough top surface of the cement seat, thereby reducing the pressure on the bottom surface of the bottom mold single plate and protecting the bottom surface of the bottom mold single plate. By providing a cement coating, the bottom plate of the rectangular side groove is sandwiched between the cement coating and the support platform, so that the bottom mold single plate is fixed in position by fixing the rectangular side groove.

[0024] The beneficial effects of the installation method of a PC component casting mold platform provided by the present invention are: the method has a fast installation speed, is easy to level, has a low construction cost, has a good fixing effect, can quickly and effectively realize the installation of the above-mentioned PC component casting mold platform, and during actual installation, the splicing mode and the number of splicing blocks can be selected according to different sites, and the adaptability is high.

[0038] Example

[0039] Please refer to Figures 1 to 6The present embodiment provides a PC component casting mold platform, which includes a plurality of bottom mold single plates 10 and a plurality of support platforms 20 distributed in an array. The support platforms 20 are used to support the bottom mold single plates 10 to prevent the bottom mold single plates 10 from being uneven due to uneven ground. The bottom mold single plates 10 are rectangular plates, and the edges of the plurality of bottom mold single plates 10 are connected to form a rectangular bottom mold. In the present embodiment, the length, width, thickness and other parameters of each bottom mold single plate 10 are the same, and the plurality of bottom mold single plates 10 are connected by wide edges to form a bottom mold. In other embodiments, the corresponding splicing method can be selected according to the actual situation of the site, and the bottom mold formed only needs to be rectangular. Specifically, the bottom mold single plate 10 includes an upper splint 11 and a lower splint 12, and a support assembly is sandwiched between the upper splint 11 and the lower splint 12, and the support assembly includes two horizontal plates 13 and two vertical plates 14, and the two horizontal plates 13 and the two vertical plates 14 are connected in a criss-cross shape to enclose a rectangular middle cavity 15, and the length and width of the rectangular middle cavity 15 are respectively smaller than the length and width of the bottom mold single plate 10, so that four rectangular side grooves 16 are formed around the rectangular middle cavity 15; the distance between the support platforms 20 in each column is the same as the width of the bottom mold single plate 10, and the distance between the support platforms 20 in each row is 1 / n of the length of the bottom mold single plate 10, and n is an integer greater than or equal to 3. By setting a plurality of bottom formwork single plates 10, the bottom formwork as a whole is divided into blocks, which is convenient for transportation, hoisting, transfer and construction on the one hand, and can also be spliced ​​and constructed according to different construction environments and requirements on the other hand, with high flexibility; further, by setting the bottom formwork single plate 10 to include an upper clamping plate 11 and a lower clamping plate 12, and sandwiching a supporting component between the two, the bottom formwork single plate 10 is reduced in weight and the structural performance is reinforced in a multi-layer sandwich manner. Specifically, the supporting component includes two transverse plates 13 and two longitudinal plates 14, and the two transverse plates 13 and the two longitudinal plates 14 are connected in a well shape. The two transverse plates 13 and The two longitudinal plates 14 are arranged to form a rectangular central cavity 15, thereby forming a hollow grid-like sandwich structure, which effectively reduces weight while improving structural performance; by setting the length and width of the rectangular central cavity 15 to be smaller than the length and width of the bottom mold single plate 10, four rectangular side grooves 16 are formed between the outer side surfaces of the two transverse plates 13 and the two longitudinal plates 14 and the upper clamping plate 11 and the lower clamping plate 12. On the one hand, the rectangular side grooves 16 can be provided with reinforcing ribs therein to further improve the structural strength, and structures that are convenient for lifting can also be added therein. The above-mentioned reinforcing ribs or lifting structures can be hidden in the rectangular side grooves 16 without affecting the overall splicing of the bottom mold.By setting a number of support platforms 20 to be arranged in an array, and making the distance between each column of support platforms 20 the same as the width of the bottom die single board 10, and the distance between each row of support platforms 20 be 1 / n of the length of the bottom die single board 10, where n is an integer greater than or equal to 3, while ensuring the support performance, it is convenient for the transportation and erection of the bottom die single board 10 thereon, and at the same time convenient for the disassembly of the bottom die single board 10. Specifically, make the distance between each column of support platforms 20 the same as the width of the bottom die single board 10. When erecting, the two sides in the width direction of the bottom die single board 10 are respectively erected on two adjacent support platforms 20 in each row, preventing the middle part of the bottom surface of the bottom die single board 10 from bearing the support force. At the same time, the support assembly can also prevent the middle part from bending. By setting the distance between each row of support platforms 20 to be 1 / n of the length of the bottom die single board 10, where n is an integer greater than or equal to 3. In this embodiment, n = 3. When erecting, make a column of support platforms 20 be evenly arranged directly below the two sides in the width direction of the bottom die single board 10 and be evenly distributed along the long side, providing stable support performance.

[0040] In order to further improve the structural performance of the bottom die single board 10 and explain the specific position and structure of the rectangular side groove 16, the planes where the cross plate 13 and the longitudinal plate 14 are located are both perpendicular to the plane where the bottom die single board 10 is located. The longitudinal plate 14 is arranged parallel to the long side of the bottom die single board 10. The C-shaped area between the outer side of the longitudinal plate 14 and the upper clamping plate 11 and the lower clamping plate 12 is one of the rectangular side grooves 16. A number of lifting lugs 161 are evenly arranged in the rectangular side groove 16. The lifting lugs 161 are provided with lifting holes 1611. The a number of lifting lugs 161 on both sides of the bottom die single board 10 are symmetrically arranged. By setting the planes where the cross plate 13 and the longitudinal plate 14 are located to be both perpendicular to the plane where the bottom die single board 10 is located, a number of right-angle structures are formed between the upper clamping plate 11, the lower clamping plate 12 and the cross plate 13 and the longitudinal plate 14, effectively improving the structural performance of the bottom die single board 10. By setting the longitudinal plate 14 to be parallel to the long side of the bottom die single board 10 and the cross plate 13 to be parallel to the short side of the bottom die single board 10, four rectangular side grooves 16 are formed, ensuring that the cross section of the rectangular side groove 16 remains rectangular. By arranging a number of lifting lugs 161 in the rectangular side groove 16 and opening lifting holes 1611 on the lifting lugs 161, the lifting lugs 161 on both sides of the bottom die single board 10 are symmetric, which is convenient for hoisting and balancing. Since the lifting lugs 161 are hidden in the rectangular side groove 16, it will not hinder the splicing when the bottom die single boards 10 are spliced, effectively avoiding the generation of gaps.

[0041] In order to further explain the structure of the support platform 20, the support platform 20 includes a trapezoidal cement seat 21 and a metal plate 22 laid on the top surface of the cement seat 21. The bottom mold single plate 10 is mounted on the metal plate 22. A cement coating 23 is laid in the rectangular side groove 16 above the support platform 20, and the cement coating 23 is connected to the corresponding cement seat 21. By setting the support platform 20 to include the cement seat 21, and setting the cement seat 21 to be a trapezoidal platform, the cement seat 21 has better support performance and prevents the cement seat 21 from deformation and collapse. By setting the metal plate 22, the smooth top surface of the metal plate 22 is used to replace the rough top surface of the cement seat 21, thereby reducing the pressure on the bottom surface of the bottom mold single plate 10 and protecting the bottom surface of the bottom mold single plate 10. By setting the cement coating 23, the bottom plate of the rectangular side groove 16 is sandwiched between the cement coating 23 and the support platform 20, so that the bottom mold single plate 10 is fixed in position by fixing the rectangular side groove 16.

[0042] In order to further improve the supporting performance of the support platform 20 and prevent extrusion deformation in the middle of the bottom mold single plate 10, the several support platforms 20 included in each row of the support platforms 20 are located directly below the two sides of the width direction of the bottom mold single plate 10, and the several support platforms 20 included in each column of the support platforms 20 are located directly below the long side of the bottom mold single plate 10.

[0043] In order to further improve the fixing performance at the cement coating 23, the plurality of support platforms 20 included in each row of the support platforms 20 are located directly below the plurality of lifting ears 161, and are connected to the rectangular side groove 16 and the lifting ears 161 through the cement coating 23. Since a T-shaped structure is formed between the lifting ears 161 and the upper clamping plate 12 and the lower clamping plate 13, the contact area of ​​the cement coating 23 can be effectively increased, thereby improving the fixing performance.

[0044] In order to further limit the pouring area 31 , a plurality of groups of side molds 30 are distributed in an array on the top surface of the bottom mold, and each group of side molds 30 is arranged to form a rectangular pouring area 31 .

[0045] In order to further improve the performance of the PC component, an air supply pipe 40 is laid on the edge of the bottom mold, and the air supply pipe 40 is connected to a plurality of air outlet pipes 41, each of which is located between two adjacent sets of side molds 30, and a tarpaulin (not shown) is provided on the outer sealing cover of the bottom mold. By providing the air supply pipe 40 and the air outlet pipe 41, and connecting the air supply pipe 40 to an external steam supply device, the curing steam is sprayed out by the air outlet pipe 41 to cure the PC component, and by providing the tarpaulin, a sealed curing environment is formed.

[0046] The present invention also proposes a method for installing the above-mentioned PC component casting mold platform, comprising the following steps:

[0047] S1. Prepare and level a plurality of support platforms 20 distributed in an array, wherein the distance between the support platforms 20 in each column is the same as the width of the bottom mold single board 10, and the distance between the support platforms 20 in each row is 1 / n of the length of the bottom mold single board 10, where n is an integer greater than or equal to 3. Using cement to prepare the support platforms 20 in advance is not only convenient to prepare, but also can be effectively leveled by tools such as a level ruler before the cement is dry, which is low-cost and can effectively improve installation efficiency.

[0048] S2. Hoist and install several bottom mold single plates 10 on the support platform 20 in sequence, and connect the edges of adjacent bottom mold single plates 10 to form a rectangular bottom mold. When installing, two adjacent bottom mold single plates 10 share a column (or row) of support platforms 20 to form effective support for the joint, which is the most vulnerable part. When splicing, pay attention to aligning and tightly fitting the edges of adjacent bottom mold single plates 10 without leaving any gaps.

[0049] S3. Lay a cement coating 23 above the support platform 20 in the rectangular side groove 16, and connect the cement coating 23 to the corresponding support platform 20. By applying the cement coating 23 and utilizing the connection between the cement coating 23 and the cement seat 21 of the corresponding support platform 20, the bottom mold single plate 10 is further fixed to prevent the bottom mold single plate 10 from horizontal displacement or sliding.

[0050] S4. Fix the side mold 30 on the top surface of the bottom mold to form a casting area 31.

[0051] This method has fast installation speed, is easy to level, has low construction cost, and has good fixing effect. It can quickly and effectively realize the installation of the casting formwork platform of the above-mentioned PC component. During actual installation, the splicing mode and the number of splicing blocks can be selected according to different sites, and it has high adaptability.

[0052] In summary, the present invention provides a PC component casting mold platform, which divides the bottom mold into blocks by setting a plurality of bottom mold single plates, which is convenient for transportation, hoisting, transfer and construction on the one hand, and can also be spliced ​​and constructed with bottom molds of different sizes according to different construction environments and needs on the other hand, and has high flexibility; further, by setting the bottom mold single plate including an upper clamping plate and a lower clamping plate, and sandwiching a supporting component between the two, a multi-layer sandwich method is adopted to reduce the weight and strengthen the structural performance of the bottom mold single plate. Specifically, the supporting component includes two horizontal plates and two vertical plates, and the two horizontal plates and the two vertical plates It is connected in a criss-cross shape, with two horizontal plates and two vertical plates surrounding a rectangular middle cavity, thereby forming a hollow grid-like sandwich structure, which effectively reduces weight while improving structural performance; by setting the length and width of the rectangular middle cavity to be smaller than the length and width of the bottom mold single plate, four rectangular side grooves are formed between the outer side surfaces of the two horizontal plates and the two vertical plates and the upper and lower plywood plates. On the one hand, the rectangular side grooves can be equipped with reinforcing ribs to further improve the structural strength, and structures that are convenient for lifting can also be added therein. The above-mentioned reinforcing ribs or lifting structures can be hidden in the rectangular side grooves without affecting the overall splicing of the bottom mold. By setting up a number of support platforms, they are distributed in an array, and the distance between each column of support platforms is the same as the width of the bottom mold single board, the distance between each row of support platforms is 1 / n of the length of the bottom mold single board, n is an integer greater than or equal to 3, while ensuring the supporting performance, it is convenient for the bottom mold single board to be transported and erected thereon, and it is also convenient for the disassembly of the bottom mold single board. Specifically, the distance between each column of support platforms is the same as the width of the bottom mold single board. When erecting, the two sides of the bottom mold single board in the width direction are respectively erected on two adjacent support platforms in each row to prevent the middle part of the bottom surface of the bottom mold single board from bearing the supporting force. At the same time, the support assembly can also prevent the middle part from bending. By setting the distance between each row of support platforms to 1 / n of the length of the bottom mold single board, n is an integer greater than or equal to 3, when erecting, a row of support platforms are evenly distributed directly below the two sides of the bottom mold single board in the width direction, and evenly distributed along the long sides, to provide stable supporting performance. By setting the planes of the transverse plate and the longitudinal plate to be perpendicular to the plane of the bottom mold single board, a plurality of right-angle structures are formed between the upper and lower splints and the transverse and longitudinal plates, which effectively improves the structural performance of the bottom mold single board. By setting the longitudinal plate to be parallel to the long side of the bottom mold single board and the transverse plate to be parallel to the short side of the bottom mold single board, four rectangular side grooves are formed to ensure that the cross section of the rectangular side groove remains rectangular. By setting a plurality of lifting ears in the rectangular side groove and opening lifting holes on the lifting ears, the lifting ears on both sides of the bottom mold single board are symmetrical, which is convenient for lifting and balancing. Since the lifting ears are hidden in the rectangular side groove, they will not hinder the splicing of the bottom mold single board when splicing, and effectively avoid the generation of gaps. By setting the support platform including the cement seat, and setting the cement seat in a trapezoidal platform shape, the cement seat has better supporting performance and prevents the cement seat from deformation and collapse. By setting the metal plate, the smooth top surface of the metal plate is used to replace the rough top surface of the cement seat, the pressure on the bottom surface of the bottom mold single board is reduced, and the bottom surface of the bottom mold single board is protected.By setting the cement covering, the bottom plate of the rectangular side groove is sandwiched between the cement covering and the support platform, so that the bottom mold single plate is fixed in position by fixing the rectangular side groove.
