Description

Technical Field

[0001] The present invention relates to the technical field of precast concrete piles, and in particular to a production system for producing precast concrete components. The present invention also relates to a method for producing precast concrete piles. Background Art

[0002] Precast piles used in the construction field mainly include two types of precast concrete piles and steel piles. Precast concrete piles are concrete piles with steel cages inside that are prefabricated in factories. They are characterized by being able to withstand large loads, being strong and durable, and having a fast construction speed.

[0003] Precast concrete piles are mostly processed and manufactured in the working area of ​​the factory. The production process usually includes preparing concrete materials, preparing steel cages, placing steel cages into molds, tensioning, injecting concrete materials into molds, steam curing, demoulding, stacking, etc. Since the entire production process is carried out in a factory with limited area and space, it is particularly important to reasonably arrange and control each production process.

[0004] Moreover, once the manufacturing system is put into use, it will be very difficult and costly to change it. Therefore, the scientific and reasonable design of the concrete precast pile manufacturing system and manufacturing process is the key scientific research direction of each manufacturer when building or upgrading a factory and before formal production.

[0005] For example, CN109676783A discloses a fixed formwork prestressed concrete component production line and production process, which is equipped with a mixing area, a distribution area, a cage weaving area and a molding area. The mixing area is provided with a cementitious material silo and a mixing tower. The distribution area is provided with a secondary material distribution hopper, a distribution hopper and a distribution vehicle. The cage weaving area is provided with a cage weaving machine and a steel cage stacking area. The molding area is provided with a tensioning machine, a tensioning machine track and a fixed formwork. The fixed formwork is provided with a tensioning longitudinal beam and a tensioning cross beam. A plurality of steam pipes are evenly arranged at the bottom of the fixed formwork, and the steam pipes are connected to the steam main pipe.

[0006] The mold of this production line is not easy to deform, which solves the technical problems of large mold size, back and forth movement affecting product quality, large steam consumption and high cost when entering the steam curing tank for curing. However, since it uses a crane to lift the material hopper for material distribution, and the location design of each processing area is not very reasonable, it does not have a very obvious advantage in production efficiency and manufacturing cost.

A spacing component is provided between the bottom of the first layer of component module and the top of the second layer of component module to ensure a spacing distance between the two.

[0013] Preferably, the fixed formwork platform is provided with at least one group of tensioning connectors in its inner cavity, and the tensioning connectors divide the inner cavity in which it is located into at least two sub-cavities, each of which is used to accommodate a component module that is connected by tensioning connectors after being placed therein and can simultaneously tension the steel cage, so as to simultaneously produce at least two precast concrete components in the same length direction.

[0014] Preferably, a mold storage area is provided in the area from the other end of the working area in the transverse direction to the second fixed mold platform area, and the mold storage area is used to store component molds of different specifications.

[0015] Preferably, the running height of the material transport vehicle is higher than that of the material distribution vehicle, and the material distribution vehicle can selectively run under different material transport vehicles, so that the selected material transport vehicle can distribute the carried concrete materials to the material distribution vehicle.

[0016] Preferably, the fabric trolley is erected above the fixed mold platform through a transverse support beam mechanism, the fixed mold platform is provided with longitudinal tracks on both sides at the top, and the transverse support beam mechanism is configured to be able to run on the longitudinal tracks along the length direction of the fixed mold platform; the transverse support beam mechanism is provided with a transverse track, and the fabric trolley is configured to be able to run on the transverse track along the width direction of the fixed mold platform.

[0018] Preferably, it further comprises a concrete mixing mechanism arranged on the conveying rail to supply materials to the material transport vehicle.

[0019] To achieve the above another object, the present invention provides a method for producing a precast concrete component, which uses any of the above precast concrete component production systems to produce the precast concrete component, comprising:

[0020] Mixing and preparing concrete materials according to a formula, and supplying the prepared concrete materials to a material transport vehicle, which transports the concrete materials along a conveyor track;

[0021] In the steel cage processing area, a cage weaving machine is used to make steel cages, and the finished steel cages are stored in the steel cage stacking area;

[0022] The component module is hoisted into the inner cavity of the fixed mold platform by a crane;

[0023] The steel cage is hoisted into the mold cavity of the component mold set by a crane, and both ends of the steel cage are connected to the tensioning mechanism respectively;

[0024] In the tensioning operation area, the steel cage is tensioned along the length direction of the steel cage by a tensioning machine, so that the steel cage has prestress;

[0025] Control the placing truck to run to the material receiving position, and the material transport truck distributes the concrete materials to the placing truck;

[0026] The placing vehicle runs along the length direction of the fixed mold platform and injects concrete material into the mold cavity of the component mold group during the running process;

[0027] After resting, steam is introduced into the fixed mold platform for steam curing;

[0028] The precast concrete components in the mold cavity are lifted by a crane for demoulding;

[0029] The precast concrete components are transported from the pile exit channel to outside the site.

[0030] The concrete prefabricated component production system provided by the present invention is provided with a longitudinal pile-out channel in the working area, and a steel cage processing area, a steel cage stacking area and a first fixed formwork area are sequentially provided in the area from one end of the working area in the transverse direction to the pile-out channel. The first fixed formwork area is provided with a plurality of fixed formworks, and a material distribution vehicle capable of reciprocating along the length direction thereof is provided above each fixed formwork. A conveying rail is provided on one side of the first fixed formwork area, and the length of the conveying rail corresponds to the first fixed formwork area. A material transport vehicle capable of reciprocating laterally is provided on each of the conveying rails. After receiving the material, the material transport vehicle can run along the conveying rail to the end area of ​​the fixed formwork where material distribution is required, and then the material distribution vehicle moves to the position where the material transport vehicle is located, and the material transport vehicle distributes the concrete material to the material distribution vehicle, which then runs along the length direction of the fixed formwork and injects the concrete material into the component module inside the fixed formwork during the running process. Since at least two conveying rails extending in the transverse direction and parallel to each other are provided, multiple material distribution vehicles can be at different positions in the transverse direction when distributing materials. Moreover, during the material transportation process, multiple material distribution vehicles operate independently of each other without affecting each other and without waiting. At the same time, in the fixed mold area, precast concrete components can be produced relatively independently at the same time, and the processes such as steel cage placement, concrete distribution, and demoulding can be operated relatively independently without interfering with each other, thus reducing waiting time. The entire production system is reasonably arranged and the process is smooth. It can significantly improve production efficiency while saving area and space.

[0031] In addition, the present invention adopts a concrete placing vehicle for placing materials, and does not need to adopt a crane to lift the placing vehicle for placing materials, which reduces the operating frequency and distance of the crane, is beneficial to reducing energy consumption, and avoids the potential safety hazards caused by too frequent lifting operations. The time required for the concrete placing vehicle from receiving materials to completing the placing is relatively short, and the transportation distance and transportation time of the steel cage, tensioning parts and precast concrete components are also relatively short, which can speed up the production rhythm, improve production capacity, and reduce the labor intensity and manufacturing costs of workers while ensuring product quality.

[0032] The precast concrete component production method provided by the present invention applies the above-mentioned precast concrete component production system to produce precast concrete components. Since the above-mentioned precast concrete component production system has the above-mentioned technical effects, the precast concrete component production method should also have corresponding technical effects.

[0041] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0042] In this article, the terms "upper, lower, inside, outside" and the like are established based on the positional relationships shown in the drawings. The corresponding positional relationships may also change depending on the drawings, and therefore cannot be understood as absolute limitations on the scope of protection; moreover, relational terms such as "first" and "second" and the like are merely used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.

[0043] Please refer to Figure 1 , Figure 1 The present invention is a schematic structural diagram of a precast concrete component production system disclosed in an embodiment of the present invention.

[0044] As shown in the figure, in a specific embodiment, the concrete precast component production system provided by the present invention is mainly composed of a crane and a work area located in a production workshop. The entire production workshop is generally rectangular in a top view, with a certain length and width, and the size can be determined according to the specific plan. Inside the production workshop, a crane for performing various lifting operations is erected in a cross-over manner in the upper area, and the work area based on the ground is divided into multiple work areas. The equipment in each work area respectively performs one or several links of the entire production process, and all equipment operates in an overall coordinated manner according to the set process to achieve orderly production of concrete precast components.

[0045] A longitudinal pile-out channel 1 is provided in the middle area of ​​the working area, and a steel cage processing area 2, a steel cage stacking area 3 and a first fixed mold platform area 4 are provided in sequence from one end of the working area in the transverse direction (i.e. the left end as shown in the figure) to the pile-out channel, and a mold storage area 5 and a second fixed mold platform area 6 are provided in sequence from the other end of the working area in the transverse direction (i.e. the right end as shown in the figure) to the pile-out channel.

[0046] The pile removal channel 1 does not have to be strictly located in the center of the working area, and can be Figure 1 It can be shifted to the left or to the right by a certain distance and should be considered to be in the middle area of ​​the working area.

[0047] Since the first fixed mold platform section 4 and the second fixed mold platform section 6 have similar structures, in order to save space, the first fixed mold platform section 4 is mainly introduced in detail below. The first fixed mold platform section 4 and the second fixed mold platform section 6 may be different in specific structures. For example, the lengths and numbers of their fixed mold platforms may be inconsistent, and the number of components that can be produced simultaneously in the length direction may be different.

[0048] The steel cage is mainly composed of main bars distributed in a rectangular array and spiral bars wrapped and welded on the outer periphery of the main bars. Both ends of the main bars are usually provided with piers and sleeve nuts that are locked in the opposite direction with the piers. Therefore, the steel cage processing area 2 can be subdivided into a main bar processing area (including straightening, cutting, nut installation, piers, etc.), a spiral bar processing area, and a cage weaving area where the main bars and spiral bars are welded into a steel cage by a cage weaving machine. The steel cages made in the steel cage processing area can be unloaded to the steel cage stacking area 3 for standby use, so as to store a sufficient number of steel cages to meet the demand for steel cages in subsequent processes.

[0049] The right side of the steel cage stacking area 3 is the first fixed mold platform area 4, which is provided with a plurality of fixed mold platforms 7 (four in the figure), each of which is provided with a tensioning longitudinal beam 8 and a tensioning cross beam 9, respectively. The tensioning longitudinal beam 8 and the tensioning cross beam 9 form a long strip inner cavity closed in the circumferential direction, and a steam pipe 10 is provided at the bottom thereof. The steam pipe 10 is connected to the steam main pipe, and steam can be introduced into the fixed mold platform 7 through the steam pipe 10 for steam curing. When steam curing is performed, a steam curing cover 27 can be provided on the top of the fixed mold platform 7 or covered with canvas to prevent steam leakage and ensure the steam curing effect (see Figure 5 ).

[0050] The inner cavity of the fixed mold platform 7 is used to place the component module 11, which is composed of a plurality of component molds arranged side by side horizontally and connected as a whole. Each of the component molds can produce one component, and one component module 11 can produce multiple components at the same time. For example, if 3 to 6 component molds are arranged side by side, 3 to 6 components can be produced at the same time. The entire component module 11 can be lifted in or out of the fixed mold platform 7 by a crane.

[0051] The tensioning beams 9 at both ends of the fixed mold platform 7 are respectively provided with tensioning mechanisms including tensioning wire rods. When the steel cage is tensioned, the tensioning longitudinal beams 8 and the tensioning beams 9 bear the tensioning force, and the component mold 11 does not bear the tensioning force. Therefore, the component mold 11 can be made of thinner steel.

[0052] Two conveying rails are provided on one side of the first fixed mold platform area 4 and the second fixed mold platform area 6 (the upper side as shown in the figure), which are the first conveying rail 12 and the second conveying rail 13. The first conveying rail 12 and the second conveying rail 13 extend in the transverse direction and are parallel to each other. The lengths thereof correspond to the first fixed mold platform area 4 and the second fixed mold platform area 6, that is, the lengths of the first conveying rail 12 and the second conveying rail 13 are equivalent to the overall widths of the first fixed mold platform area 4 and the second fixed mold platform area 6. A material transport vehicle 14 is provided on each conveying rail. When working, the material transport vehicle 14 can reciprocate laterally along the conveying rail so as to distribute concrete materials to the material distribution vehicle 15. There can be one, two or three material transport vehicles 14 on each conveying rail. The concrete mixing plant 16 is located at one end of the two conveying rails (the right end as shown in the figure), and is used for mixing and preparing concrete materials according to the formula and supplying the mixed concrete materials to the material transport vehicle 14.

[0053] Please refer to Figure 4 , Figure 4 It is a structural schematic diagram of a fabric carriage mounted above a fixed mold platform.

[0054] As shown in the figure, a material distribution vehicle 15 capable of reciprocating along the length direction thereof is respectively provided above each fixed mold platform 7 of the first fixed mold platform area 4. Each material distribution vehicle 15 is erected above the fixed mold platform 7 through a transverse support beam mechanism 17. The fixed mold platform 7 is provided with longitudinal tracks 18 on both sides at the top. The transverse support beam mechanism 17 is configured to be able to run on the longitudinal tracks 18 along the length direction of the fixed mold platform 7; the transverse support beam mechanism 17 is provided with a transverse track 19, and the material distribution vehicle 15 is configured to be able to run on the transverse track 19 along the width direction of the fixed mold platform 7, so as to move to the right a certain distance after injecting material into the two-layer component module 11 on the left inside the same fixed mold platform 7, and then inject material into the two-layer component module 11 on the right.

[0055] The material distribution vehicle 15 has a funnel-shaped cavity, and its injection port is located at the bottom. When the injection port is opened, the concrete material can automatically flow out into the mold cavity of the component mold 11 under the action of gravity. In order to prevent the concrete material from flowing to the outside of the component mold 11, inclined baffle plates 20 can be set on both sides of the injection port of the material distribution vehicle 15, or on both sides of the openings of each inner cavity of the fixed mold platform 7. Under the guiding action of the baffle plates 20, the flow direction of the concrete material can be restricted to prevent the concrete material from entering the area outside the component mold 11 and causing pollution.

[0056] The rear part of the material placing vehicle 15 may be provided with a vibrating mechanism to vibrate the concrete material injected into the mold cavity; the rear part of the vibrating mechanism may also be provided with a plastering mechanism to plaster the upper surface of the concrete material after vibration.

[0057] Please refer to Figure 5 , Figure 5 This is a schematic diagram of the structure when the material distribution vehicle moves under the material transport vehicle.

[0058] As shown in the figure, the operating height of the material transport vehicle 14 is higher than that of the material distribution vehicle 15. The material distribution vehicle 15 can selectively operate under different material transport vehicles 14 so that the selected material transport vehicle 14 can distribute the carried concrete materials to the material distribution vehicle 15, and then the material distribution vehicle 15 operates along the length direction of the fixed formwork platform 7, and distributes the materials during the operation, injecting the concrete materials into the mold cavity of the component mold 11 inside the fixed formwork platform 7.

[0059] The other side of the working area (the lower side as shown in the figure) is provided with a first tensioning operation area 21 corresponding to the first fixed die table area 4 and a second tensioning operation area 22 corresponding to the second fixed die table area 6. The ends of the fixed die table 7 are provided with tensioning mechanisms including tensioning screws, so that the steel cage in the component die set 11 placed in the fixed die table 7 is tensioned by a tensioning machine 23, so that the steel cage has prestress.

[0060] Since the steel bar cage weaving machine, the laying machine 23, the concrete mixing plant 16 and other equipment can be realized by using existing technologies, these equipments will not be described in detail in this article.

[0061] The "in sequence" mentioned above mainly refers to the general arrangement order of the steel cage processing area 2, the steel cage stacking area 3, the first fixed mold platform area 4, the pile outlet channel 1, the second fixed mold platform area 6 and the mold storage area 5, and does not exclude the possibility that other functional areas may be set up between these areas.

[0062] The cranes include a first crane 24 located on one side of the pile-exiting channel 1 and a second crane 25 located on the other side of the pile-exiting channel 1. Two first cranes 24 can be set, and their operating areas cover the steel cage processing area 2, the steel cage stacking area 3, the first fixed mold area 4 and the pile-exiting channel 1 to meet the needs of actual production. For example, when one of the first cranes 24 performs the operation task of lifting the steel cage and placing it in the left area of ​​the first fixed mold area 4, the other first crane 24 can simultaneously perform the operation task of lifting the concrete prefabricated component from the right area of ​​the first fixed mold area 4 for demoulding, and so on, so as to ensure that each production process can be connected in an orderly manner, avoid crane interference and time-consuming waiting due to insufficient cranes. Similarly, two second cranes 25 can also be set.

[0063] Since at least two conveying rails extending in the transverse direction and parallel to each other are provided, multiple material distribution vehicles 14 can be at different positions in the transverse direction when distributing materials. Moreover, during the material transportation process, multiple material distribution vehicles 14 operate independently of each other without affecting each other and without waiting. At the same time, in the first fixed mold area 4 and the second fixed mold area 6, precast concrete components can be produced relatively independently at the same time, and the processes such as steel cage placement, concrete distribution, and demolding can be operated relatively independently without interfering with each other, thereby reducing waiting time. The entire production system is reasonably arranged and the process is smooth. It can significantly improve production efficiency while saving area and space.

[0064] In addition, the concrete placing vehicle 15 is used for placing materials, and there is no need to use a crane to lift the placing vehicle 15 for placing materials, which reduces the operating frequency and distance of the crane, is beneficial to reducing energy consumption, and avoids the potential safety hazards caused by too frequent lifting operations. The time required for the concrete placing vehicle 15 from receiving materials to completing the placing is relatively short, and the transportation distance and transportation time of the steel cage, tensioning components and precast concrete components are also relatively short, which can speed up the production rhythm, improve production capacity, and reduce the labor intensity and manufacturing costs of workers while ensuring product quality.

[0065] like Figure 2 , Figure 3As shown, in some other embodiments, the fixed formwork 7 of the first fixed formwork area 4 and the second fixed formwork area 6 is provided with at least one group of tensioning connectors 26 in its inner cavity, and the tensioning connector 26 divides the inner cavity in which it is located into at least two sub-cavities, each sub-cavity is used to accommodate a component module 11 that is connected by the tensioning connector 26 after being placed in it and can simultaneously tension the steel cage, so as to simultaneously produce at least two precast concrete components in the same length direction. For example, under the restriction that the total length does not exceed 31m, precast components of different combinations such as 16m+15m, 16m+14m, 15m+15m, etc. can be produced.

[0066] It can be understood that two or three groups of tension connectors 26 can be further provided in the inner cavity of the fixed formwork platform 7. When two groups of tension connectors 26 are provided, three precast concrete components of the same or different lengths can be produced at one time. For example, under the restriction that the total length does not exceed 31m, precast concrete components of different combinations such as 16m+6m+8m, 16m+7m+7m, 15m+6m+9m, 15m+7m+8m, 14m+6m+10m, 12m+6m+12m can be produced. When three groups of tension connectors 26 are provided, four precast concrete components of the same or different lengths can be produced at one time. For example, under the restriction that the total length does not exceed 31m, precast concrete components of different combinations such as 8m+7m×3, 7m×4, 6m×2+8m×2 can be produced.

[0067] In actual production, different positions and numbers of tensioning connections 26 can be set in different fixed mold platforms 7 as needed, or different positions and numbers of tensioning connections 26 can be set in different inner cavities of the same fixed mold platform 7 .

[0068] In this embodiment, the steel cage stacking area 3 is divided into two stacking partitions along the length direction of the stacked steel cages, one of which is close to the conveying rail to supply the steel cages to the upper area of ​​the fixed formwork 7, and the other stacking partition is close to the first tensioning operation area 21 to supply the steel cages to the lower area of ​​the fixed formwork 7.

[0069] Please refer to Figure 6 , Figure 6 The schematic diagram is a structure in which two component modules of different specifications are placed in the inner cavity of the same fixed mold platform, and each component module is stacked in two layers.

[0070] As shown in the figure, in some other embodiments, the fixed mold platform 7 is designed to be able to accommodate at least two layers of component molds 11. During production, the first layer component mold 11 is first injected, and then the second layer component mold 11 is stacked on the first layer component mold 11, and then the second layer component mold 11 is injected. The first layer component mold 11 and the second layer component mold 11 can be separated by a certain distance by spacing components such as gaskets to prevent the bottom of the second layer component mold 11 from affecting the normal molding of the upper surface of the first layer component.

[0071] In this way, the vertical space of the fixed mold platform 7 can be fully utilized. Under the condition of the same floor area, the number of components that can be produced by the same fixed mold platform 7 is twice that of a single-layer fixed mold platform. If multiple layers are stacked, the number can be several times, which helps to further improve production capacity.

[0072] The inner cavity depth of the fixed mold platform 7 is greater than or equal to the height of two layers of the largest component modules 11 after being stacked, and the width is greater than or equal to the width of two rows of the largest component modules 11 after being placed, so that there is enough internal space to accommodate component modules 11 of different specifications, and the component modules 11 of smaller specifications can be placed inside (see Figure 4 ), or a component module 11 with larger dimensions can be placed (see Figure 6 ), a large number of component modules 11 of different specifications can be stored in the mold storage area 5.

[0073] On the basis of the above embodiment, if the second fixed mold platform area 6 on the right side of the pile-exiting channel 1 is omitted and the lengths of the first conveying rail 12 and the second conveying rail 13 are appropriately shortened, another embodiment can be obtained. This embodiment is equivalent to retaining only the single-sided structure located on the left side of the pile-exiting channel 1 in the above embodiment. In this case, since the fixed mold platform area is no longer divided into two parts and only has the first fixed mold platform area 4, the pile-exiting channel 1 will be located on the side of the first fixed mold platform area 4 instead of the middle area.

[0074] The above embodiments are only preferred solutions of the present invention, and are not limited thereto. On this basis, targeted adjustments can be made according to actual needs to obtain different implementation methods. For example, three or four conveyor rails are set on one side of the first fixed mold platform area 4 and the second fixed mold platform area 6 so that four or more material transport vehicles 14 can transport concrete materials at the same time, or, without using the component mold 11, a mold cavity for placing a steel cage is directly formed on the fixed mold platform 7, etc. Since there are many possible implementation methods, they will not be explained one by one here.

[0075] In addition, the technical solutions between the embodiments can be combined with each other, but it should be based on the fact that ordinary technicians in the field can implement it. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0076] In addition to the above-mentioned precast concrete component production system, the present invention also provides a precast concrete component production method, which uses the above-mentioned precast concrete component production system to produce precast concrete components, comprising:

[0077] Mixing concrete materials according to the formula, and supplying the prepared concrete materials to the material transport vehicle 14, which transports the concrete materials along the conveyor rail;

[0078] In the steel cage processing area 2, a cage weaving machine is used to make steel cages, and the made steel cages are stored in the steel cage stacking area 3;

[0079] The component mold set 11 is hoisted into the interior of the fixed mold platform 7 of the first fixed mold platform area 4 and the second fixed mold platform area 6 by a crane;
