Description

Technical Field

[0001] The invention relates specifically to a method for manufacturing a composite wall module, a device for manufacturing a composite wall module and a composite wall module for nuclear engineering. Background Art

[0002] The composite wall module is a prefabricated building component, usually made of concrete and steel cage, used to quickly assemble and construct the walls of a building. This modular wall is prefabricated in the factory and then transported to the construction site for superposition and combination to form the wall structure of the building. It has the advantage of fast construction speed and is therefore widely used. The composite wall module is mainly composed of a steel cage and prefabricated concrete blades on both sides.

[0003] At present, the existing manufacturing process is to place the steel cage frame on the formwork table to cast the concrete blades on both sides. The two sides of the steel cage frame are marked as side A and side B respectively.

[0004] Side. During the pouring of the blade on the A side, place the A side of the steel cage frame downward and the B side upward on the formwork, then pour concrete directly into the formwork, and after the concrete solidifies, you will get the A side blade. During the pouring of the B side blade, place the B side of the steel cage frame downward and the A side upward on the formwork. At this time, due to the obstruction of the A side blade, you need to first pour the blade concrete on the formwork in advance, then place the composite wall after the mold is turned over, and place the B side steel cage frame downward, slowly press it into the concrete with the help of external force to make the B side concrete blade.

[0026] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of the present invention.

[0027] In the description of the present invention, the terms “first” and “second” are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0028] In the description of the present invention, each unit and module involved may correspond to only one physical structure, or may be composed of multiple physical structures, or multiple units and modules may be integrated into one physical structure; the units and modules involved may be implemented by software or by hardware, for example, the units and modules may be located in a processor.

[0029] In the description of the present invention, the functions and steps marked in the flowcharts and block diagrams of the present invention may occur in an order different from that marked in the drawings if there is no conflict.

[0030] First of all, it should be noted that the composite wall module of nuclear engineering is mainly composed of a steel cage skeleton and prefabricated concrete blades on both sides. The module length is generally 6m, 9m, and 12m, and the height is the same as the floor height, generally 4.5 to 5m; the wall thickness is mainly 500mm, 600mm, 800mm, 1000mm, and 1500mm; the thickness of the blades on both sides varies from 50 to 150mm; when the wall thickness is greater than 800mm, double-layer reinforcement is generally used; when the wall thickness is less than 600mm, single-layer reinforcement is generally used. After the composite wall module is hoisted and installed at the construction site, concrete can be poured directly in the middle cavity to form a concrete shear wall. In the field of nuclear engineering, with the popularization and application of prefabricated composite wall modules, the work of wall reinforcement engineering and template laying can be greatly reduced.

[0031] The general method of making composite walls in the field of civil construction is as follows: the first step is to make a steel cage skeleton; the second step is to place the steel cage skeleton on a mold platform with vibration and curing functions, set the thickness of the concrete protective layer, and then pour concrete with a thickness of 50 to 150 mm, and then vibrate and cure the concrete to form the A-side concrete blade; the third step is to turn the composite wall module over after the A-side concrete blade reaches a certain strength, and at the same time, pour 50 to 150 mm of concrete on the mold platform in advance, and turn on the vibration function of the mold platform; the fourth step is to turn the composite wall after the mold is turned over, with the steel cage skeleton on the B side facing down, and slowly press it into the concrete with the help of external force to make the B-side concrete blade, and fix it after the steel protective layer thickness is met, and then perform concrete curing. The fifth step is to hoist the completed composite wall to the storage area for curing after the B-side concrete blade reaches a certain strength, and the composite wall module is completed.

[0032] There are many embedded parts, casings and other wall items on the composite wall of nuclear engineering, and the manufacturing process of the steel cage skeleton can be consistent with the civil construction method. However, the walls of nuclear engineering are densely reinforced, and when pouring the A-side blade concrete in the civil construction method, the steel contamination problem is more serious; and when making the B-side concrete blade, due to the large number of embedded parts, casings and other items on the nuclear engineering wall, it will hinder the sinking of the steel cage, resulting in the failure of the B-side blade to be successfully made.

[0033] In order to solve the above problems, improve the production efficiency of nuclear engineering composite wall modules and promote the industrialization of nuclear engineering civil construction, it is necessary to develop a nuclear engineering composite wall module production process to achieve efficient production of nuclear engineering composite wall modules.

[0034] Example 1

[0035] See also Figure 1 , Figure 2 and Figure 3 The present invention discloses a method for manufacturing a composite wall module, comprising the following steps:

[0036] Obtain a steel cage skeleton 1, on which a wall item is installed. The steel cage skeleton 1 includes two steel meshes, which are arranged opposite to each other and located on both sides of the steel cage skeleton, and the wall item runs through at least one of the steel meshes on both sides. Wall items include: embedded parts, sleeves, etc. For the convenience of description, the steel mesh on any one side of the steel meshes on both sides is set as the A-side steel mesh, and the steel mesh on the other side is set as the B-side steel mesh. Figure 1 As shown, the wall item passes through at least one of the steel meshes on both sides, that is, the wall item passes through the steel mesh on side A, or, passes through the steel mesh on side B, or, passes through the steel mesh on side A and the steel mesh on side B.

[0037] The concrete delivery conduit 5 is extended into the interior of the steel cage frame 1, and the steel mesh sheets on both sides of the steel cage frame 1 are respectively cast to obtain a composite wall module.

[0038] It should be noted that the method for making the composite wall module in the present invention does not need to consider the influence of wall items such as embedded parts and sleeves, and can be applied to the composite wall modules of nuclear engineering. The A-side steel mesh and the B-side steel mesh of the steel cage skeleton are connected by multiple tie rods, and the tie rods extend along the thickness direction of the composite wall (i.e., the third direction). The number of concrete delivery ducts is multiple. In the process of pouring the A-side blade or the B-side blade, multiple concrete delivery ducts are inserted between the tie rods, starting from one end of the steel cage skeleton, and gradually moving or retracting to the other end, thereby completing the pouring of the concrete blade.

[0039] Compared with the prior art, the B side of the steel cage skeleton needs to be slowly pressed into the concrete with the help of external force to make the B side concrete blade. This production method does not need to consider the influence of wall items such as embedded parts and casings, and is more suitable for the production of nuclear engineering composite wall modules. Therefore, the production method of the composite wall module can realize the efficient production of nuclear engineering composite wall modules, thereby effectively improving the efficiency of nuclear engineering civil construction and promoting the industrialization process of nuclear engineering construction.

[0040] In other words, unlike the composite walls in the civil construction field, the composite walls of nuclear projects have relatively more embedded parts, casings and other wall items, and their layout is irregular, making it impossible to use the traditional method of pressing down the steel cage to make the concrete blades on both sides. This technology effectively solves the problem of casting the blades on both sides of the composite wall modules of nuclear projects, and can realize the efficient production of composite wall modules of nuclear projects, thereby effectively improving the efficiency of civil construction of nuclear projects and promoting the industrialization process of nuclear project construction.

[0041] The specific structure of the steel cage skeleton 1 is described as follows: Figure 1 As shown, a plurality of tie units are provided between the steel meshes on both sides, and the plurality of tie units are arranged at intervals along a first direction, each tie unit includes a plurality of tie rods, and the plurality of tie rods are arranged at intervals along a second direction, the first direction is perpendicular to the second direction, the tie rods extend along a third direction, and the third direction is perpendicular to a plane determined according to the first direction and the second direction, and both ends of the tie rods are respectively connected to the steel meshes on both sides to tie the steel meshes on both sides, and there is a casting channel between two adjacent tie units, and the casting channel extends along the second direction, and the number of casting channels is multiple.

[0042] In other words, the A-side steel mesh and the B-side steel mesh are arranged relatively spaced apart along the thickness direction (i.e., the third direction) of the composite wall, and the A-side steel mesh or the B-side steel mesh is formed by binding the transverse steel bars and the longitudinal steel bars (wherein the transverse direction corresponds to the first direction, the longitudinal direction corresponds to the second direction, and the plane determined according to the first direction and the second direction is Figure 1 The horizontal plane shown in FIG. 1 ). The steel mesh on the A side and the steel mesh on the B side are connected by a plurality of tie units, and the plurality of tie units are arranged in a lateral interval, and each tie unit includes a plurality of tie rods, and the plurality of tie rods are arranged in a lateral interval. The tie rods extend in the thickness direction of the composite wall, and one end of the tie rods is connected to the steel mesh on the A side, and the other end is connected to the steel mesh on the B side. The interval between two adjacent tie units is a casting channel. A plurality of casting channels are arranged between the steel mesh on the A side and the steel mesh on the B side, and the plurality of casting channels are arranged in a lateral interval.

[0043] Specifically, the steps are: extending the concrete delivery conduit 5 into the interior of the steel cage frame, and casting the blades on the steel mesh on both sides of the steel cage frame 1 to obtain a composite wall module. Specifically, the concrete delivery conduit 5 is extended into the casting channel to enter the interior of the steel cage frame 1, and casting the blades on the steel mesh on both sides of the steel cage frame 1 to obtain a composite wall module.

[0044] This step is implemented by using a pouring device. One end of the concrete delivery conduit 5 is provided with a discharge port, and the other end is connected to a pressure pumping unit 6 (concrete pressure pumping device). The concrete delivery conduit 5 extends along the second direction, and the central axis of the concrete delivery conduit 5 is on the same extension line as the extension direction of the pouring channel of the steel cage skeleton. The concrete delivery conduit 5 can be extended and retracted along its own axis direction, and then can be extended into the pouring channel to enter the interior of the steel cage skeleton 1. The pressure pumping unit 6 outputs concrete through the concrete delivery conduit 5. The blades are poured on the A side and the B side of the steel cage skeleton 1 respectively by the pouring device to obtain a composite wall module.

[0045] The number of concrete delivery conduits 5 is multiple, which may be 3, 4 or 5. The diameter of the concrete delivery conduits 5 is 150-180 mm, for example, 150 mm, 160 mm, 170 mm, 180 mm. The diameter of the conduit should be compatible with the spacing between two adjacent tie rods, that is, it should be smaller than the spacing between two adjacent tie rods, so as to ensure that the conduit can extend into the casting channel of the steel cage. The multiple concrete delivery conduits 5 are arranged along the first direction (i.e., the width direction of the mold platform 4), and the concrete delivery conduits 5 can be extended and retracted along the second direction (i.e., the length direction of the mold platform 4) so ​​that the discharge port of the concrete moves along the second direction.

[0046] When the steel cage skeleton 1 is placed on the formwork platform, each concrete delivery conduit 5 is directly opposite to a pouring channel. The concrete delivery conduit 5 extends into the pouring channel, and concrete can be poured into the pouring channel. For example, Figure 2 and Figure 3 As shown, there are three concrete delivery conduits 5, and three concrete delivery conduits 5 can be used to simultaneously pour concrete in three pouring channels. During the pouring of the A-side blade 2 or the B-side blade 3, the concrete delivery conduit 5 is inserted between the tie rods, starts pouring from one end of the pouring channel of the steel cage skeleton 1, and gradually moves or retracts toward the other end, thereby completing the pouring of the concrete blade.

[0047] After the pouring of blade concrete in one area is completed, the concrete delivery conduit 5 is moved to another area to pour blade concrete. In other words, concrete is poured into each pouring channel in turn along the preset pouring direction (for example, from the left to the right). After the pouring of all pouring channels is completed, the pouring of blade concrete on side A / side B is completed. Then, the steel cage skeleton is turned over and concrete is poured into the steel mesh on the other side.

[0048] Furthermore, during the pouring of the blade on the A side, the steel cage frame 1 is placed on the formwork 4 with the A side facing downward and the B side facing upward, and then concrete is directly poured into the formwork 4, and the blade on the A side is obtained after the concrete solidifies. During the pouring of the blade on the B side, the steel cage frame 1 needs to be placed on the formwork 4 with the B side facing downward and the A side facing upward. Therefore, after the pouring of the blade on the A side is completed, the A side and the B side of the steel cage frame 1 need to be turned over before pouring the blade 3 on the B side.

[0049] Furthermore, the concrete pressure pumping equipment (i.e., the pressure pumping unit 6) can use a pressure pump to pressurize and transport concrete, and the concrete pressure pumping equipment can also use a concrete spiral material distribution system. The concrete pressure pumping equipment is connected to the concrete delivery conduit 5 and is used to output concrete through the concrete delivery conduit 5.

[0050] In some embodiments, the concrete pressure pumping equipment (pressure pumping unit 6) is carried on the working vehicle. After the working vehicle transports the concrete pressure pumping equipment and the concrete delivery conduit 5 to the target position, the concrete pressure pumping equipment is started and concrete is output to the mold platform 4 through the concrete delivery conduit 5. The concrete delivery conduit 5 has a telescopic function, and a large diameter conduit nested in a small diameter conduit telescopic method can be adopted. The discharge port is moved in the horizontal direction by telescoping the concrete delivery conduit 5. Specifically, the concrete delivery conduit 5 includes a first pipe section and a second pipe section. The central axis of the first pipe section and the second pipe section are on the same extension line, the diameter of the first pipe section is smaller than the diameter of the second pipe section, one end of the second pipe section is connected to the concrete pressure pumping equipment, and the other end is connected to the first pipe section. One end of the first pipe section is the discharge port, and the other end is partially inserted into the second pipe section, so as to be connected to the second pipe section. The first pipe section can extend or retract relative to the second pipe section. The extension or retraction of the first pipe section can be achieved manually or by an electric telescopic drive. The telescopic end of the telescopic drive member (for example, a linear motor, a cylinder, a hydraulic cylinder, etc.) is connected to the first pipe segment, and the telescopic end of the telescopic drive member can move along the central axis of the first pipe segment and the second pipe segment, thereby driving the first pipe segment to extend / retract relative to the second pipe segment. A guide structure is provided between the first pipe segment and the second pipe segment to guide the first pipe segment to move along its own axial direction. For example, a protrusion is provided on the inner side wall of the second pipe segment, and a guide groove is provided on the side wall of the first pipe segment, which extends along the central axis direction of the first pipe segment. The protrusion on the inner wall of the second pipe segment is embedded in the guide groove, and the first pipe segment can be guided axially. In this embodiment, the discharging port is controlled to move in the horizontal direction by telescoping the concrete conveying conduit 5. The advantage of this method is that when there is a wall item on the motion trajectory of one of the concrete conveying conduits 5, the concrete conveying conduit 5 can be retracted to easily avoid the wall item without affecting the pouring of concrete in other concrete conveying conduits 5.

[0051] In some other embodiments, the working vehicle may also move along the second horizontal direction, thereby driving the concrete pressure pumping equipment and the concrete conveying conduit 5 to move along the second horizontal direction, that is, the discharge port moves along the horizontal direction.

[0052] In the prior art, when pouring the B-side blade 3, the B-side blade 3 cannot be poured directly due to the obstruction of the A-side blade 2. Usually, it is necessary to first pour the B-side blade 3 concrete on the mold platform 4 in advance, and then turn the mold over and place the B-side steel cage frame 1 downward, and slowly press it into the concrete with the help of external force to make the B-side concrete blade. However, for the nuclear engineering composite wall, there are many wall items such as embedded parts and sleeves that need to be installed on it, which will hinder the sinking of the steel cage frame 1, resulting in the failure of the B-side blade 3 to be successfully made. That is, the existing installation method of this composite wall module cannot meet the production requirements of the nuclear engineering composite wall module.

[0053] In this embodiment, a new method for making a composite wall module is proposed to solve this problem. Figure 1 and Figure 3 As shown, the pouring of the B-side blade 3 is achieved through the concrete delivery conduit 5 in the pouring equipment, especially by inserting the concrete delivery conduit 5 of the pouring equipment into the pouring channel to achieve the pouring of the blade concrete. The concrete delivery conduit 5 has a discharge port, and the discharge port is driven to move in the horizontal direction of the formwork 4 by the extension and contraction of the concrete delivery conduit 5, so that the blade concrete can be laid flat. Then, the concrete is vibrated and cured through the formwork 4 to obtain the B-side blade 3. Compared with the prior art, the manufacturing method in this embodiment does not need to consider the influence of wall items such as embedded parts and sleeves, and can be applied to the manufacture of nuclear engineering composite wall modules.

[0054] The benefit of pouring in this way is that it allows the blades to be formed simultaneously during the pouring process, which reduces the time consumption in the construction stage and improves the overall construction progress. Moreover, the concrete is in direct contact with the steel skeleton during the pouring process, which can form a better bond and reduce the risk of separation and weak connection. In addition, by pouring the concrete evenly through the conduit, the density and uniformity of the concrete are higher, and the appearance of bubbles and voids is reduced. That is, this method can not only avoid the influence of wall items, but also further reduce the probability of failure of pouring the blades on the A side and the B side, and is more suitable for the production of nuclear engineering composite wall modules.

[0055] See also Figure 2 and Figure 3 In the step of extending the concrete delivery conduit 5 into the pouring channel to enter the interior of the steel cage frame 1, and respectively pouring leaf plates on the steel meshes on both sides of the steel cage frame 1 to obtain the composite wall module, the method also includes: placing the steel mesh on one side of the steel cage frame 1 downward and horizontally on the mold platform 4.

[0056] It should be noted that a first pad (not shown in the figure) is also installed on the outer side of the steel mesh on the A side of the steel cage skeleton 1. A second pad (not shown in the figure) is also installed on the outer side of the steel mesh on the B side. The first pad is used to maintain a first protective layer gap between the A side of the steel cage skeleton 1 and the upper surface of the formwork 4. The second pad is used to maintain a second protective layer gap between the B side of the steel cage skeleton 2 and the upper surface of the formwork 4. During the casting of the blade on the A side, concrete is filled into the first protective layer gap to form the first steel protective layer of the blade on the A side. Similarly, during the casting of the blade on the B side, concrete is filled into the second protective layer gap to form the second steel protective layer of the blade on the B side.

[0057] Specifically, the first pad and the second pad can be made of steel and can be installed on the A-side steel mesh / B-side steel mesh of the steel cage skeleton 1 by binding, welding, etc. The first steel bar protective layer and the second steel bar protective layer are respectively located on the outside of the A-side steel mesh and the B-side steel mesh, which can effectively isolate the steel bars and prevent the intrusion of moisture, chloride ions, etc., thereby slowing down or preventing the corrosion of the steel bars, especially in a humid or salty environment.

[0058] See also Figure 2 In some embodiments, the step of extending the concrete delivery conduit 5 into the pouring channel to enter the interior of the steel cage frame 1, and pouring leaf plates on the steel mesh sheets on both sides of the steel cage frame 1 to obtain a composite wall module includes:

[0059] Step 1, extending the concrete delivery conduit 5 into the pouring channel, pouring concrete onto the steel mesh on the downward side of the steel cage framework 1, and obtaining a single-sided blade after the concrete solidifies;

[0060] Step 2, retracting the concrete delivery conduit 5;

[0061] Step 3, turn over the steel cage frame 1 so that the blade on one side faces upward and the steel mesh on the other side faces downward, and place it horizontally on the mold platform 4;

[0062] Step 4: Repeat step 1 to obtain another single-sided blade, and the manufacturing steps of the composite wall module are completed.

[0063] In this embodiment, by extending the concrete delivery conduit 5 into the pouring channel, concrete is poured into the steel mesh on the downward side of the steel cage frame 1, which can effectively avoid the influence of wall items. In addition, the concrete can better immerse the steel mesh on the downward side, that is, the concrete directly contacts the steel frame during the pouring process, which can form better bonding force and reduce the risk of separation and weak connection.

[0064] Moreover, when pouring the B-side blade, compared with directly aligning the concrete outlet of the concrete pressure pumping equipment with the pouring channel, the concrete pressure pumping equipment applies pressure to the concrete so that the concrete is sprayed into the pouring channel. In this embodiment, the concrete is guided and output through the concrete delivery conduit 5, which can make the concrete more evenly spread on the formwork 4. In particular, when pouring the B-side blade 3, it can be avoided that the concrete is concentrated in the surrounding area of ​​the steel cage frame 1 and cannot be evenly spread on the formwork.

[0065] Furthermore, the concrete delivery conduit 5 is provided with a discharge port, and the discharge port is used to discharge concrete. The concrete delivery conduit 5 extends along the second direction, and the concrete delivery conduit 5 can be extended and retracted along its own axial direction, so that the discharge port moves in the horizontal direction.

[0066] The above step 1 specifically includes:

[0067] Step 11: The concrete delivery conduit 5 extends from one end of the pouring channel into the interior of the steel cage skeleton 1, and the discharge port is moved to the other end of the pouring channel.

[0068] Step 12: retract the concrete delivery conduit 5 so that the discharge port moves along the second direction, and at the same time, output concrete to the mold platform 4 through the discharge port until the concrete delivery conduit 5 completely leaves the pouring channel.

[0069] Step 13: The concrete delivery conduit 5 repeats steps 11-12 for each pouring channel in sequence until the concrete reaches a preset thickness.

[0070] Step 14: Vibrate and cure the concrete through the formwork platform 4, and obtain a single-sided blade after the concrete solidifies.

[0071] It should be noted that the preset thickness of the concrete is between 50 and 150 mm, for example: 50 mm, 100 mm, 150 mm, which is determined according to the thickness of the pads (the first pad and the second pad) and the steel meshes on both sides. The preset thickness of the concrete must at least be able to completely immerse the steel meshes. For example, the thickness of the first pad plus the thickness of the steel mesh is 70 mm, that is, the distance between the upper end of the steel mesh and the upper surface of the formwork 4 is 70 mm, and the preset thickness of the blade concrete can be set to 80 mm.

[0072] Exemplarily, the A-side steel mesh of the steel cage skeleton 1 is placed on the formwork platform 4 with the steel mesh facing downward, and the A-side blade concrete is output by moving the discharge port of the concrete delivery conduit 5 in the horizontal direction of the formwork platform 4. The A-side blade 2 concrete is vibrated and cured to obtain the A-side blade 2. Then, the A-side and B-side of the steel cage skeleton 1 are turned over so that the B-side of the steel cage skeleton 1 faces downward and is placed horizontally on the formwork platform 4. The discharge port of the concrete delivery conduit 5 is moved in the horizontal direction of the formwork platform 4, and the B-side blade 3 concrete is output to the formwork platform 4 through the discharge port. The B-side blade 3 concrete is vibrated and cured through the formwork platform 4 to obtain the B-side blade 3.

[0073] Specifically, the process of vibrating and curing the concrete is as follows: the formwork platform 4 is equipped with a built-in vibrator, which can vibrate according to a preset amplitude and frequency while pouring the concrete to ensure the compactness and uniformity of the concrete. The formwork platform 4 is designed with a humidifying device or a spraying system, which can automatically spray water mist after the concrete is poured to keep the concrete surface moist and achieve the curing of the A-side blade 2 and the B-side blade 3.

[0074] Through such a B-side blade casting process, the obstruction of the A-side blade can be avoided, and at the same time, it will not be affected by a large number of wall items on the steel cage frame 1, thereby avoiding the failure of the B-side blade production. That is, this method can greatly improve the finished product qualification rate of the nuclear engineering composite wall.

[0075] The function of flipping the A side and the B side of the steel cage frame 1 can be achieved by using equipment such as a crane or a gantry crane.

[0076] The following is a further description of the method for making the composite wall module:

[0077] The technical problem to be solved by this method is to develop a production process suitable for nuclear engineering composite wall modules in view of the current situation that nuclear engineering composite walls cannot be produced mechanized and automatically by civilian methods. The technology can realize the efficient production of nuclear engineering composite wall modules, thereby effectively improving the efficiency of nuclear engineering civil construction and promoting the industrialization process of nuclear engineering construction.

[0078] In order to achieve the above objectives, a manufacturing method suitable for the production of nuclear engineering composite wall modules is proposed, and the process flow is as follows:

[0079] The nuclear engineering composite wall module consists of a steel cage frame 1, a concrete blade plate on the A side, a concrete blade plate on the B side, and wall items.

[0080] The first step is to produce the steel cage frame 1 module, and at the same time, install wall embedded parts, sleeves and other items on it.

[0081] The second step is to lift the produced steel cage frame 1 and place it on a mold platform 4 with vibration and maintenance functions to set a steel protection layer; then pour the A side blade 2 through the concrete delivery duct 5, and the blade thickness varies from 50 to 150 mm; as the concrete is poured, the concrete delivery duct 5 needs to be continuously moved outward until the concrete pouring is completed, and then the duct is moved to another steel bar space for pouring.

[0082] The concrete delivery conduit 5 can be in various forms such as a pressure pouring system and a spiral distribution system. The conduit diameter is preferably such that it can be inserted into the steel cage. The conduit can be one or more, and the concrete can be poured and distributed on both sides of the concrete at the same time. After the distribution is completed, the concrete of the blade plate 2 on the A side is vibrated and maintained by the mold platform 4.

[0083] In the third step, after the concrete of the blade plate 2 on the A side has been cured to the age, the component is lifted and the mold is turned over. The steel cage on the B side is placed downward on the mold platform 4, and the component is fixed after the steel protection layer is set.

[0084] The fourth step is to pour the B-side blade 3 through the concrete delivery conduit 5, and the blade thickness varies from 50 to 150 mm; as the concrete is poured, the concrete delivery conduit 5 needs to be continuously moved outward until the concrete pouring is completed, and then the conduit is moved to another steel bar space. Then, the concrete of the B-side blade 3 is vibrated and cured by the formwork 4.

[0085] Step 5: After the concrete blade on side B reaches a certain strength, the completed composite wall will be hoisted to the storage area for storage.

[0086] In other words, if Figure 1-4 As shown, the present invention provides a manufacturing process of a nuclear engineering composite wall module, wherein the nuclear engineering composite wall module consists of a steel cage skeleton 1, wall items, A-side concrete blade plates, and B-side concrete blade plates.

[0087] The steel cage is composed of longitudinal and transverse horizontal steel bars, tie bars and wall items, wherein the horizontal spacing of the steel bars is 200mm. The concrete blades on both sides include A-side blade 2 and B-side blade 3, wherein the blade thickness varies from 50 to 150mm. The equipment for pouring concrete includes a formwork 4 with vibration and maintenance functions, a concrete delivery duct 5, and concrete pressure pumping equipment; wherein, the side length of each side of the formwork 4 needs to be greater than the length of the wall module by about 1m, and the concrete pressure pumping equipment is connected to the concrete delivery duct 5, and the diameter of the concrete delivery duct 5 varies from 150 to 180mm. The pumping duct (i.e. the above-mentioned concrete delivery duct 5) has a telescopic function, and a large-diameter duct nested in a small-diameter duct telescopic method can be adopted, and a pressure pump can be used for pressurized concrete delivery, or a concrete spiral distribution system can be used.

[0088] The production process of the present invention:

[0089] First, the reinforcement cage skeleton is mass-produced in the factory automatically; at the same time, embedded parts, sleeves and other wall items are placed on the reinforcement cage skeleton 1, and its outer surface is flush with the wall surface, and it is ensured to be firm and reliable.

[0090] Second, lift the produced steel cage frame 1, place it on the mold platform 4 with vibration and maintenance functions, set the steel protection layer and fix the steel cage frame 1; at this time, the steel bars on the four sides need to extend 300 to 500 mm from the edge of the blade to facilitate the mechanical connection between adjacent composite wall modules; pour the A side blade 2 through the concrete delivery duct 5, and maintain the component after pouring.

[0091] Third, after the blade 2 on side A reaches the lifting strength, the component is lifted and turned over, so that the concrete blade on side A faces upward and the steel cage on side B faces downward, and is placed on a mold platform 4 with vibration and maintenance functions. After setting a steel bar protective layer, the component is fixed; at the same time, the steel bars on the four sides need to extend out of the edge of the blade by 300 to 500 mm to facilitate the mechanical connection between adjacent composite wall modules.

[0092] Fourth, the concrete delivery conduit 5 is extended into the steel cage frame 1, and the vibration function of the mold platform 4 is turned on to pour the concrete blade on the B side, and then it is cured after the pouring is completed.

[0093] After the B-side blade 3 reaches the lifting strength, the completed composite wall is hoisted to the storage area for storage; at this point, the production of the nuclear engineering composite wall module is completed.

[0094] In summary, the beneficial effects of this method are as follows:

[0095] Different from the composite walls in the civil construction field, there are relatively more embedded parts, casings and other items on the composite walls of nuclear engineering, and their arrangement is irregular, so it is impossible to use the traditional method of pressing down the steel cage to make the concrete blades on both sides. This invention effectively solves the problem of casting the blades on both sides of the composite wall modules of nuclear engineering.

[0096] Most of the composite walls in the civil construction field do not have items. When the A-side blade 2 is manufactured, the steel cage frame 1 is placed on the formwork table 4, and after the concrete protective layer is set, the concrete is directly poured; when the B-side blade 3 is manufactured, a certain thickness of concrete is first poured on the vibration table, and then the steel cage frame 1 is pressed into the concrete by external force, and finally cured to form a composite wall module.

[0097] There are many embedded parts, sleeves and other items on the composite wall module of nuclear engineering. When the blades on both sides are made, if the traditional method of pressing down the steel cage skeleton 1 with external force is adopted, the existence of many wall embedded parts and other items will prevent the steel cage skeleton 1 from moving downward. The main process of this method is to place the manufactured steel cage skeleton 1 on the mold platform 4, extend the conveying conduit into the steel cage, and cast the concrete blades on both sides, which solves the problem that the concrete blades on both sides of the composite wall module of nuclear engineering cannot be cast quickly, and can realize the efficient production of the composite wall module of nuclear engineering, effectively improve the efficiency of civil construction of nuclear engineering, and promote the industrialization process of nuclear engineering construction.

[0098] Example 2

[0099] The invention also discloses a manufacturing device for a composite wall module, comprising an acquisition device and a pouring device.

[0100] The acquisition device is used to acquire a steel cage frame 1, on which a wall item is installed. The steel cage frame 1 includes two steel meshes, which are arranged opposite to each other and are respectively located on both sides of the steel cage frame, and the wall item passes through at least one of the steel meshes on both sides. The casting device includes a concrete delivery conduit 5 and a driving unit, and the driving unit (not shown in the figure) is connected to the concrete delivery conduit 5. The driving unit is used to extend the concrete delivery conduit 5 into the interior of the steel cage frame 1, and perform leaf plate casting on the steel meshes on both sides of the steel cage frame 1 to obtain a composite wall module.

[0101] It should be noted that the acquisition device can use a conveying device such as a mechanical arm or a crane to transport the tied steel cage frame 1 to the mold platform 4. The steel cage frame 1 can be made by manual tying by staff or by existing automated equipment.

[0102] Furthermore, a plurality of tie units are provided between the steel meshes on both sides, and the plurality of tie units are arranged at intervals along the first direction, and each tie unit includes a plurality of tie rods, and the plurality of tie rods are arranged at intervals along the second direction, and the first direction is perpendicular to the second direction, and the tie rods extend along a third direction, and the third direction is perpendicular to a plane determined according to the first direction and the second direction, and the two ends of the tie rods are respectively connected to the steel meshes on both sides to tie the steel meshes on both sides, and a casting channel is provided between two adjacent tie units, and the casting channel extends along the second direction, and the number of casting channels is multiple. The driving unit is used to extend the concrete delivery conduit 5 into the casting channel to enter the interior of the steel cage frame 1, and respectively cast the steel meshes on both sides of the steel cage frame 1 with leaf plates to obtain a composite wall module.

[0103] The steel cage frame also includes a first pad and a second pad, which are respectively installed on the outside of the two steel meshes. The first pad and the second pad are used to maintain a protective layer gap between the steel meshes on both sides of the steel cage frame 1 and the upper surface of the formwork 4. After the concrete is poured, a steel protective layer is formed at the protective layer gap.

[0104] The pouring equipment further includes a mold platform 4 and a pressure pumping unit 6 (i.e., concrete pressure pumping equipment). The upper surface of the mold platform 4 extends along a plane direction determined by the first direction and the second direction, and is used to support the steel cage skeleton 1. A discharge port is provided at one end of the concrete delivery conduit 5, and the other end is connected to the pressure pumping unit 6. The concrete delivery conduit 5 extends along the second direction. The concrete delivery conduit 5 can be retracted along its own axial direction, and then can be extended into the pouring channel to enter the interior of the steel cage skeleton 1. The pressure pumping unit 6 outputs concrete through the concrete delivery conduit 5.

[0105] In some embodiments, the driving unit can be implemented by a working vehicle (not shown in the figure) and a telescopic driving member (not shown in the figure). Specifically, the telescopic driving member, the concrete conveying conduit 5 and the pressure pumping unit 6 (i.e., the concrete pressure pumping equipment) are all installed on the working vehicle, and the working vehicle is used to drive the concrete conveying conduit 5 and the pressure pumping unit 6 (i.e., the concrete pressure pumping equipment) to move along the first direction (i.e., the width direction of the formwork 4). The telescopic driving member is connected to the concrete conveying conduit 5, and is used to drive the concrete conveying conduit 5 to telescope along the second direction (i.e., the length direction of the formwork 4), and then extend into the interior of the steel cage skeleton 1. The concrete conveying conduit 5 includes a first pipe section and a second pipe section. The telescopic end of the telescopic driving member (for example: a linear motor, a cylinder, a hydraulic cylinder, etc.) is connected to the first pipe section, and the telescopic end of the telescopic driving member can move along the central axis of the first pipe section and the second pipe section, thereby driving the first pipe section to extend / retract relative to the second pipe section.

[0106] In addition, in some embodiments, the driving unit can be directly implemented by a work vehicle. Specifically, the concrete delivery conduit 5 and the pressure pumping unit 6 (i.e., the concrete pressure pumping equipment) are both installed on the work vehicle. The work vehicle can move in a first direction and can move in a second direction. The work vehicle can drive the concrete delivery conduit 5 to move in the second direction and then extend into the interior of the steel cage frame 1.

[0107] When the steel cage skeleton 1 is placed on the formwork platform, each concrete delivery conduit 5 is directly opposite to a pouring channel. By driving the concrete delivery conduit 5 into the pouring channel through the telescopic drive member, concrete can be poured into the pouring channel. For example, Figure 2 and Figure 3As shown, there are three concrete delivery conduits 5, and three concrete delivery conduits 5 can be used to simultaneously pour concrete in three pouring channels. During the pouring of the A-side blade 2 or the B-side blade 3, the concrete delivery conduit 5 is inserted between the tie rods, starts pouring from one end of the pouring channel of the steel cage skeleton 1, and gradually moves or retracts toward the other end, thereby completing the pouring of the concrete blade.

[0108] After the pouring of blade concrete in one area is completed, the concrete delivery conduit 5 is moved to another area by a work vehicle to pour blade concrete. In other words, concrete is poured into each pouring channel in turn along the preset pouring direction (for example, from the left to the right). After the pouring of all pouring channels is completed, the pouring of blade concrete on side A / side B is completed. Then, the steel cage skeleton is turned over and concrete is poured into the steel mesh on the other side.

[0109] The device also includes a flipping device (not shown in the figure), which is used to flip the first side steel mesh and the second side steel mesh of the steel cage skeleton 1 placed on the mold platform 4.

[0110] The device also includes a control unit, which is used to control the pouring equipment and the turning equipment to implement the manufacturing method in Example 1.

[0111] The control unit includes a first control module, a second control module and a third control module. The first control module is electrically connected to the driving unit, and is used to control the driving unit to extend the concrete delivery conduit 5 into the pouring channel, and pour concrete into the steel mesh on the downward side of the steel cage skeleton 1, and obtain a single-sided blade after the concrete solidifies. The second control module is electrically connected to the driving unit, and is used to control the driving unit to retract the concrete delivery conduit 5. The third control module is electrically connected to the flipping device and the first control module, and is used to control the flipping device to flip the steel mesh on the first side and the steel mesh on the second side of the steel cage skeleton 1, so that the steel mesh on the second side of the steel cage skeleton 1 faces downward and is placed horizontally on the mold platform 4. The third control module is also used to send a control signal to the first control module after the flipping device completes the flipping, and the first control module controls the driving unit again according to the control signal to extend the concrete delivery conduit 5 into the pouring channel, and pour concrete into the steel mesh on the downward side of the steel cage skeleton 1, and obtain another single-sided blade after the concrete solidifies.

[0112] Specifically, the control unit can be a software module, or a PLC control circuit can be used to implement control. Exemplarily, a position sensor can be installed on the mold platform 4 to determine whether the steel cage skeleton 1 is in place, and when it is determined that the steel cage skeleton 1 is in place, a start signal is sent to the first control module, and the first control module controls the drive unit to extend the concrete delivery conduit 5 into the pouring channel, and concrete is poured into the steel mesh on the lower side of the steel cage skeleton 1, and a single-sided blade is obtained after the concrete solidifies. The third control module can also be a position sensor installed on the mold platform 4, which is used to send a control signal to the first control module after the flipping device completes the flipping, and the first control module controls the drive unit again according to the control signal to extend the concrete delivery conduit 5 into the pouring channel, and concrete is poured into the steel mesh on the lower side of the steel cage skeleton 1, and another single-sided blade is obtained after the concrete solidifies.

[0113] like Figure 5 As shown, the mold platform 4 in the pouring equipment can adopt the existing mold platform 4 with vibration and maintenance functions, for example: the multifunctional mold platform 4 of model HT-DGNFZMT. The concrete pressure pumping equipment can adopt the existing pressurized pouring system and spiral material distribution system to realize concrete pouring, for example: the commercially available grouting machine of model LBT6000B can be used, and the grouting can be realized by connecting the concrete conveying conduit 5 with the grouting outlet of the grouting machine.

[0114] In addition, the turning device may be a crane or a gantry crane or other equipment, as long as it can turn over the steel cage frame 1.

[0115] In summary, the device in this embodiment adopts the manufacturing method in Example 1 for control, thereby solving the problem that the concrete blades on both sides of the composite wall modules of nuclear engineering cannot be poured quickly, and can realize the efficient production of composite wall modules of nuclear engineering, effectively improve the efficiency of civil construction of nuclear engineering, and promote the industrialization process of nuclear engineering construction.

[0116] Example 3

[0117] See also Figure 4 The present invention also discloses a nuclear engineering composite wall module, which is manufactured by the manufacturing method of the composite wall module in Example 1, and includes: a steel cage frame 1, a steel cage frame 1, an A side blade 2 and a B side blade 3. The A side blade 2 and the B side blade 3 are arranged relatively spaced along the thickness direction of the composite wall, the A side blade 2 and the B side blade 3 are connected by the steel cage frame 1, and a casting cavity is formed between the A side blade 2 and the B side blade 3.

[0118] Preferably, the steel cage skeleton 1 includes a steel mesh on the A side and a steel mesh on the B side, the steel mesh on the A side and the steel mesh on the B side are arranged relatively spaced apart along the thickness direction of the composite wall, and the steel mesh on the A side or the steel mesh on the B side is formed by binding and connecting the transverse steel bars and the longitudinal steel bars. The steel mesh on the A side and the steel mesh on the B side are connected by a plurality of tie rods, and the tie rods extend along the thickness direction of the composite wall.

[0119] The construction process of the composite wall module of the nuclear project is as follows: the prefabricated composite wall module is transported to the designated location of the construction site, and temporary supports are set up for the composite wall module to stabilize the composite wall module. Then, concrete is poured into the casting cavity. After the concrete solidifies, the concrete poured into the casting cavity and the adjacent components form a composite shear wall structure.

[0120] The composite wall module of the nuclear project is manufactured by adopting the manufacturing method of the composite wall module in Example 1, which can effectively improve the production efficiency of the composite wall module of the nuclear project, and can avoid the problem that the B-side blade cannot be successfully manufactured due to the large number of wall items such as embedded parts and sleeves in the composite wall of the nuclear project.

[0121] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
