Description

[0002] Precast concrete wall panels include single-layer wall panels (single-sheet wall panels) and multi-layer wall panels (sandwich wall panels), and their manufacturing process directly affects the efficiency and quality of engineering construction. With the increasing demand from the industry for the variety and flexible production of precast concrete wall panels, there is an urgent need to improve the production efficiency of precast concrete wall panels.

[0003] In related technologies, the production process generally employs single-station or dual-station serial casting, which is only applicable to the process requirements of a single product type, i.e., it can only produce single-layer or multi-layer wall panels.

Detailed Implementation

[0015] The technical problems associated with this technology include: 1. Limited production mode and difficulty in cross-line production: Existing single-station or double-station serial casting processes are typically only suitable for producing single types of wall panels, such as single-layer wall panels or sandwich wall panels. If both single-layer and sandwich wall panels are to be produced on the same line, line shutdowns for adjustments are often necessary, leading to equipment downtime and significant capacity loss. 2. Long cycle time and low efficiency: In the production process of sandwich wall panels, insulation boards and reinforcing bars can only be placed after the outer wall panels have initially set. Because the placement time of the insulation boards cannot be accurately determined, and prolonged waiting times for the concrete to initially set can prevent the effective use of other equipment, thus lengthening the overall production cycle time. 3. Inefficient quality control: The placement time of the insulation boards relies on manual experience. Placing them too early can damage the unset concrete, while placing them too late affects the interlayer bond strength, resulting in significant differences in the quality of the wall panels. 4. Low equipment utilization: When multiple products are produced on a mixed production line, equipment such as template traverse car and cloth placing machine are prone to resource conflicts (race against each other), and there is a lack of a unified scheduling algorithm to optimize equipment utilization.

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] The flowchart shown in the attached diagram is for illustrative purposes only and does not necessarily include all content and operations / steps, nor does it necessarily have to be performed in the order described. For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0018] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0019] Please see Figure 1 , Figure 1 This is a schematic block diagram of a precast concrete wall panel production apparatus provided in an embodiment of this application. The apparatus can be configured on a server or terminal device.

[0020] The precast concrete wall panel production apparatus provided in this application includes a mold (not shown in the figure), a first production line 1, a first transfer mechanism 4, a second production line 2, a second transfer mechanism 5, a third production line 3, and a control module 6. The mold is used to form precast concrete wall panels, which include single-layer wall panels and multi-layer wall panels. The multi-layer wall panels include an inner layer, several intermediate layers, and an outer layer from the inside out. The first production line 1 is used to perform the production process of single-layer wall panels and / or the production process of the outer layer of multi-layer wall panels. One end of the first transfer mechanism 4 is connected to the downstream of the first production line 1. The upstream of the second production line 2 is connected to the other end of the first transfer mechanism 4, and the second production line 2 is used to perform the production process of the intermediate layers of multi-layer wall panels. One end of the second transfer mechanism 5 is connected to the downstream of the second production line 2. The upstream of the third production line 3 is connected to the downstream of the first production line 1 and the other end of the second transfer mechanism 5, and the third production line 3 is used to perform the curing process of single-layer wall panels and / or the production process and curing process of the inner layer of multi-layer wall panels. The control module 6 is connected to the first production line 1, the first transfer mechanism 4, the second production line 2, and the second transfer mechanism 5. 5 and the third production line 3 are connected. The control module 6 is used to control the first production line 1 to transport the mold from the upstream of the first production line 1 to the downstream of the first production line 1, so as to perform the production process of single-layer wall panel and / or the outer layer production process of multi-layer wall panel through the first production line 1; control the first transfer mechanism 4 to transfer the mold from the downstream of the first production line 1 to the upstream of the second production line 2, and control the second production line 2 to transport the mold from the upstream of the second production line 2 to the downstream of the second production line 2, so as to perform the middle layer production process of multi-layer wall panel through the second production line 2; when the mold moves from the downstream of the first production line 1 to the upstream of the third production line 3, control the third production line 3 to transport the mold from the upstream of the third production line 3 to the downstream of the third production line 3, so as to perform the curing process of single-layer wall panel through the third production line 3; and / or control the second transfer mechanism 5 to transfer the mold from the downstream of the second production line 2 to the upstream of the third production line 3, and control the third production line 3 to transport the mold from the upstream of the third production line 3 to the downstream of the third production line 3, so as to perform the inner layer production process and curing process of multi-layer wall panel through the third production line 3.

[0021] It should be noted that the single-layer wall panel in this application embodiment is a single-sheet wall panel made of a single reinforced concrete material. The multi-layer wall panel is a sandwich wall panel composed of an inner layer (inner sheet wall panel), a middle layer (insulation layer), and an outer layer (outer sheet wall panel). It is understood that the production process of a single-layer wall panel is simpler than that of a multi-layer wall panel.

[0022] For example, the production process of a single-layer wall panel in this application embodiment may include formwork cleaning, oiling, formwork erection, reinforcement laying, and pouring. The production process of a multi-layer wall panel may include an outer layer production process, an intermediate layer production process, and an inner layer production process; wherein, the outer layer production process may include formwork cleaning, oiling, formwork erection, primary reinforcement laying, and primary pouring; the intermediate layer production process may include the placement of the insulation layer and secondary reinforcement laying; and the inner layer production process may include secondary pouring.

[0023] For example, control module 6 can control the first production line 1 to perform the production process of single-layer wall panels, the production process of the outer layer of multi-layer wall panels, or simultaneously perform the production processes of single-layer wall panels and the outer layer of multi-layer wall panels. Control module 6 can control the first transfer mechanism 4 to transfer the mold that has completed the outer layer production process of multi-layer wall panels to the second production line 2, and control the second production line 2 to perform the production process of the middle layer of multi-layer wall panels. Control module 6 can control the second transfer mechanism 5 to transfer the mold that has completed the outer layer production process of multi-layer wall panels to the third production line 3. Control module 6 can control the third production line 3 to perform the curing process of single-layer wall panels, the production process of the inner layer of multi-layer wall panels and the curing process, or simultaneously perform the curing process of single-layer wall panels and the production process of the inner layer of multi-layer wall panels and the curing process, so as to realize mixed-line production of single-layer wall panels and multi-layer wall panels, thereby meeting the production needs of different precast concrete wall panels and improving production efficiency.

[0024] It is understood that the first production line 1, the second production line 2, the third production line 3, the first transfer mechanism 4, and the second transfer mechanism 5 can all include tracks (not shown in the figure). When it is necessary to transfer a mold from the first production line 1 to the second production line 2, the control module 6 can control one end of the track of the first transfer mechanism 4 to connect with the track of the first production line 1, and the other end of the track of the first transfer mechanism 4 to connect with the track of the second production line 2, so that the mold can move from the first production line 1 to the second production line 2. When it is necessary to transfer a mold from the second production line 2 to the third production line 3, the control module 6 can control one end of the track of the second transfer mechanism 5 to connect with the track of the second production line 2, and the other end of the track of the second transfer mechanism 5 to connect with the track of the third production line 3, so that the mold can move from the second production line 2 to the third production line 3. For example, the control module 6 can control the first transfer mechanism 4 and the second transfer mechanism 5 with an error of no more than 3% through hydraulic synchronous control, so that the first transfer mechanism 4 and the second transfer mechanism 5 can smoothly transfer the mold.

[0025] For example, the first transfer mechanism 4 and the second transfer mechanism 5 may each include a template traverse vehicle (not shown in the figure), a roller-type traverse transfer machine (not shown in the figure), a chain transfer machine (not shown in the figure), or a gantry crane combined with a traverse transfer machine (not shown in the figure), etc.

[0026] The apparatus provided in the above embodiments includes a mold, a first production line 1, a first transfer mechanism 4, a second production line 2, a second transfer mechanism 5, a third production line 3, and a control module 6. The mold is used to form precast concrete wall panels, which include single-layer wall panels and multi-layer wall panels. The first production line 1 is used to perform the production process of single-layer wall panels and / or the outer layer production process of multi-layer wall panels. One end of the first transfer mechanism 4 is connected to the downstream of the first production line 1. The upstream of the second production line 2 is connected to the other end of the first transfer mechanism 4, and the second production line 2 is used to perform the middle layer production process of multi-layer wall panels. One end of the second transfer mechanism 5 is connected to the downstream of the second production line 2. The upstream of the third production line 3 is connected to the downstream of the first production line 1 and the other end of the second transfer mechanism 5, and the third production line 3 is used to perform the curing process of single-layer wall panels and / or the inner layer production process and curing process of multi-layer wall panels. The control module 6 is connected to the first production line 1, the first transfer mechanism 4, the second production line 2, the second transfer mechanism 5, and the third production line 3. In this embodiment, the molds are first processed through a first production line 1 to produce single-layer wall panels and / or the outer layer of multi-layer wall panels. Then, the molds that have completed the outer layer production process are transferred to a second production line 2 via a first transfer mechanism 4, where the molds are processed through the second production line 2 to produce the middle layer of multi-layer wall panels. Next, the molds that have completed the middle layer production process are transferred to a third production line 3 via a second transfer mechanism 5, where the molds are processed through the third production line 3 to produce the inner layer of multi-layer wall panels. Furthermore, when the molds that have completed the single-layer wall panel production process on the first production line 1 are moved to the third production line 3, the molds can undergo a curing process for single-layer wall panels on the third production line 3. This allows for mixed-line production of single-layer and multi-layer wall panels, thereby meeting the diverse and large-batch production needs of precast concrete wall panels and improving production efficiency.

[0027] In one exemplary implementation, such as Figure 2 As shown, the first production line 1 includes a mold cleaning mechanism 11, an oiling mechanism 12, a mold support mechanism 13, a first rebar laying mechanism 14, and a first pouring mechanism 15. The mold cleaning mechanism 11 is located upstream of the first production line 1 and is used to clean the mold. The oiling mechanism 12 is located downstream of the mold cleaning mechanism 11 and is used to spray a release agent. The mold support mechanism 13 is located downstream of the oiling mechanism 12 and is used to design the mold according to the shape and size of the single-layer wall panel and / or multi-layer wall panel. The first rebar laying mechanism 14 is located downstream of the mold support mechanism 13 and is used to lay the first precast rebar mesh in the mold. The first pouring mechanism 15 is located downstream of the first rebar laying mechanism 14 and is used to pour the first concrete in the mold and vibrate the concrete in the mold.

[0028] For example, the mold sequentially passes through a mold cleaning mechanism 11, an oiling mechanism 12, a mold support mechanism 13, a first rebar laying mechanism 14, and a first casting mechanism 15 on the first production line 1. The control module 6 can control the mold cleaning mechanism 11 and the oiling mechanism 12 to clean the mold and spray a release agent, and control the mold support mechanism 13 to select the corresponding end mold and side mold according to the thickness of a single-layer or multi-layer wall panel (e.g., 7cm or 10cm), and fix them using magnetic boxes (not shown) or bolts (not shown) to complete the mold design. The first rebar laying mechanism 14 can lay a first precast rebar mesh (not shown) in the mold.

[0029] For example, the first pouring mechanism 15 may include a placing boom (not shown) and a vibrator (not shown). The control module 6 can control the placing boom to pour the first batch of concrete into the mold according to the preset material quantity, and simultaneously control the vibrator to compact the concrete in the mold. Specifically, the preset material quantity can be determined based on the thickness of a single-layer wall panel or the outer layer thickness of a multi-layer wall panel. For example, the preset material quantity can be the amount of concrete corresponding to 90%-99.5% of the thickness, or it can be the amount of concrete corresponding to 95%-98% of the thickness.

[0030] In one exemplary implementation, such as Figure 2 As shown, the second production line 2 includes a placement mechanism 21 and a second rebar laying mechanism 22. The placement mechanism 21 is located upstream of the second production line 2 and is used to place insulation boards (not shown in the figure) in the mold. The second rebar laying mechanism 22 is located downstream of the placement mechanism 21 and is used to lay connectors (not shown in the figure) and a second precast rebar mesh (not shown in the figure) sequentially above the insulation board. The connectors are used to connect the first precast rebar mesh and the second precast rebar mesh. The control module 6 is connected to the placement mechanism 21 and the second rebar laying mechanism 22. The control module 6 is also used to control the placement mechanism 21 to place insulation boards in the mold within a preset time and to control the second rebar laying mechanism 22 to lay connectors and the second precast rebar mesh sequentially above the insulation board. The preset time is determined based on a preset fitting formula and the preset relationship between concrete thickness and time, according to the slump, thickness, and ambient temperature of the concrete poured into the mold by the first pouring mechanism 15.

[0031] For example, the mold passes sequentially through a placement mechanism 21 and a second rebar laying mechanism 22 on the second production line 2. The control module 6 can control the placement mechanism 21 to place an insulation board in the mold. The insulation board may include molded polystyrene board, extruded polystyrene board, graphite polystyrene board, etc. The control module 6 can control the second rebar laying mechanism 22 to sequentially lay connectors and a second precast rebar mesh above the insulation board, so as to connect the first precast rebar mesh and the second precast rebar mesh through the connectors.

[0032] For example, control module 6 can obtain the slump, thickness, and ambient temperature of the concrete poured into the mold by the first pouring mechanism 15 through detectors such as an automatic slump detector (not shown) and a temperature sensor (not shown). Exemplarily, control module 6 can first determine the baseline initial setting time of the concrete based on a preset fitting formula, according to the concrete slump and ambient temperature; then, based on the baseline initial setting time and the preset correspondence between concrete thickness and time, it can determine the preset time. The preset fitting formula in this embodiment is: t0 = K / (T+C); Where t0 is the reference initial setting time required for concrete to reach its initial setting state from the start of mixing; T is the ambient temperature; K is the material property coefficient, which is determined by the mix proportions of concrete type, admixtures, etc.; C is the temperature constant. In addition, K or C can be corrected by the slump of the concrete.

[0033] For example, the preset time can be represented as [t0+α, t0+β]. Here, α and β are the safe waiting time and the deadline time, determined based on the preset relationship between concrete thickness and time, respectively. It can be understood that the preset relationship between concrete thickness and time can be determined based on historical data on the placement of insulation boards and the concrete thickness.

[0034] The correspondence between the preset concrete thickness and time in this application embodiment can include: for concrete thickness less than 200mm, the corresponding α is 10 minutes and β is 15 minutes, so the preset time can be determined as [t0+10, t0+15]; for concrete thickness greater than or equal to 200mm and less than 500mm, the corresponding α is 12 minutes and β is 18 minutes, so the preset time can be determined as [t0+12, t0+18]; for concrete thickness greater than or equal to 500mm and less than 1000mm, the corresponding α is 15 minutes and β is 22 minutes, so the preset time can be determined as [t0+15, t0+22]; for concrete thickness greater than or equal to 1000mm, the corresponding α is 18 minutes and β is 25 minutes, so the preset time can be determined as [t0+18, t0+25].

[0035] The embodiments of this application determine the preset time based on the slump, thickness and ambient temperature of the concrete, and lay the insulation board within the preset time, which can avoid the situation of concrete collapse and large differences in wall panel quality.

[0036] In one exemplary embodiment, the placement mechanism 21 is equipped with a touch screen (not shown in the figure), which is connected to the control module 6. The control module 6 is used to generate countdown information for a preset time, control the touch screen to display the countdown information for the preset time in a visual form, and control the placement mechanism 21 to place the insulation board in the mold when the countdown information for the preset time stops changing.

[0037] For example, the placement mechanism 21 can be equipped with a touch screen for human-machine interaction, and the control module 6 can be equipped with a timer (not shown in the figure) to calculate the countdown information of the preset time and control the touch screen to display the countdown information of the preset time in a visual form. When the countdown information of the preset time stops changing, the placement mechanism 21 places the insulation board in the mold so that the production line staff can understand the placement time of the insulation board during inspection.

[0038] In some exemplary implementations, such as Figure 2 As shown, the third production line 3 includes a second pouring mechanism 31 and a curing mechanism 32. The second pouring mechanism 31 is located upstream of the third production line 3 and is used to pour concrete a second time in the mold and vibrate the concrete in the mold. The curing mechanism 32 is located downstream of the second pouring mechanism 31 and is used to cure the concrete in the mold to obtain single-layer wall panels and / or multi-layer wall panels. The control module 6 is connected to the second pouring mechanism 31 and the curing mechanism 32. The control module 6 is used to control the curing mechanism 32 to cure the concrete in the mold to obtain single-layer wall panels when the mold moves from the downstream of the first production line 1 to the upstream of the third production line 3; and / or to control the second pouring mechanism 31 to pour concrete a second time in the mold and vibrate the concrete in the mold, and to control the curing mechanism 32 to cure the concrete in the mold to obtain multi-layer wall panels when the second transfer mechanism 5 transfers the mold from the downstream of the second production line 2 to the upstream of the third production line 3.

[0039] For example, in the production process of a single-layer wall panel, the control module 6 controls the curing mechanism 32 on the third production line 3 to cure the concrete in the mold; in the production process of a multi-layer wall panel, the control module 6 first controls the second pouring mechanism 31 on the third production line 3 to pour concrete in the mold for the second time and vibrate the concrete in the mold, and then controls the curing mechanism 32 to cure the concrete in the mold.

[0040] The second pouring mechanism 31 in this embodiment may include a concrete placing boom (not shown) and a vibrator (not shown). The control module 6 can control the concrete placing boom to perform a second concrete pour in the mold according to the preset material quantity, and at the same time control the vibrator to compact the concrete in the mold. Specifically, the preset material quantity can be determined according to the inner layer thickness of the multi-layer wall panel. For example, the preset material quantity can be the amount of concrete corresponding to 99%-105% of the thickness, or it can be the amount of concrete corresponding to 100%-103% of the thickness.

[0041] In some exemplary embodiments, the curing unit 32 includes a curing kiln (not shown) connected to a control module 6, which controls the temperature and humidity in the curing kiln to steam cure the concrete in the mold.

[0042] For example, in this embodiment of the application, the concrete in the mold can be steam-cured to accelerate the hardening of the concrete. Specifically, the curing mechanism 32 may include a curing kiln, and the control module 6 can control the temperature and humidity in the curing kiln to ensure the curing quality of the concrete.

[0043] For example, the curing mechanism 32 in this embodiment may further include a settling area (not shown), a finishing area (not shown), and a stacking area (not shown). The control module 6 can control the third production line 3 to transport the molds to the settling area and the finishing area to store the molds waiting for curing or to cure the molds by natural drying.

[0044] In practical applications, a palletizer can be installed in the palletizing area. The control module 6 can control the palletizer to stack the molds into the curing kiln. After curing, the molds exiting the curing kiln can sequentially pass through a slitting machine, a mold removal area, and a plate ejector to perform operations such as slitting, removing end and side molds, and ejecting plates. In this embodiment, the control module 6 can control the plate ejector to tilt the molds at an angle of 80° to 85°.

[0045] In practical applications, each mold can be assigned an identification number. The control module 6 can associate each identification number with a process status to facilitate understanding the production status of different molds. The process status can include: waiting to enter the production line, mold cleaning, oiling, formwork erection, primary rebar laying, primary pouring, primary track changing, insulation board laying, secondary rebar laying, secondary track changing, secondary pouring, settling, finishing, stacking into the kiln, curing, stacking, mold removal, and side-flipping out of the mold.

[0046] The control module 6 can predict the process status within the next three cycles with a minimum cycle time of 5 seconds, and perform peak-shifting control on requests from equipment such as the pouring mechanism (brick placing machine, vibrator), moving mechanism (template traverse car), palletizer, and stacker according to priority. For example, the priority rules for different requests may include: emergency abnormal requests > curing kiln exit requests > primary pouring requests > secondary material placing requests > regular transfer requests.

[0047] In addition, data such as entry time, dwell time, equipment number, operator number, concrete batch, insulation board batch, and steel bar batch corresponding to the process status of each mold can be stored for subsequent quality traceability.

[0048] In some implementations, multiple devices (bricklayers, traverse cars) can be pre-scheduled based on rolling window prediction algorithms, genetic algorithms, greedy algorithms, or rule-based expert systems. This enables conflict prediction and staggered scheduling for the next N cycle times, resolving production line congestion issues. In the event of resource conflicts, the request signal for kiln exit from the curing kiln can be processed with the highest priority to prevent kiln congestion. Furthermore, visual sensors can be installed at the ports where the transfer mechanism and the production line intersect to determine if there is a positional deviation by identifying the markings on the mold, thereby enabling accurate mold transfer across different production lines.

[0049] In practical applications, the operating status of high-energy-consuming equipment (such as cloth placing machines and vibrators) on the production line can be dynamically adjusted according to the peak and valley periods of the power grid.

[0050] Please see Figure 3 , Figure 3 This is a schematic flowchart illustrating a method for producing precast concrete wall panels according to an embodiment of this application. The method is applied to the precast concrete wall panel production apparatus described in the above embodiment, and includes steps S101 to S103.

[0051] Step S101: Control the first production line to transport the mold from the upstream of the first production line to the downstream of the first production line so as to perform the production process of single-layer wall panel and / or the outer layer production process of multi-layer wall panel through the first production line.

[0052] Step S102: Control the first transfer mechanism to transfer the mold from the downstream of the first production line to the upstream of the second production line, and control the second production line to transport the mold from the upstream of the second production line to the downstream of the second production line, so as to perform the intermediate layer production process of the multi-layer wall panel through the second production line.

[0053] Step S103: When the mold moves from the downstream of the first production line to the upstream of the third production line, control the third production line to transport the mold from the upstream of the third production line to the downstream of the third production line so as to perform the curing process of the single-layer wall panel through the third production line; and / or control the second transfer mechanism to transfer the mold from the downstream of the second production line to the upstream of the third production line, and control the third production line to transport the mold from the upstream of the third production line to the downstream of the third production line so as to perform the inner layer production process and curing process of the multi-layer wall panel through the third production line.

[0054] In one exemplary embodiment, the method further includes step S201.

[0055] Step S201: Control the placement mechanism to place the insulation board in the mold within a preset time, and control the second steel bar laying mechanism to lay the connector and the second precast steel mesh on the insulation board in sequence. The preset time is determined based on the preset fitting formula and the preset relationship between concrete thickness and time, according to the slump, thickness and ambient temperature of the concrete poured in the mold by the first pouring mechanism.

[0056] In one exemplary embodiment, step S201 may include steps S2011 to S2013.

[0057] Step S2011: Generate countdown information for the preset time.

[0058] Step S2012: Control the touch screen to display the countdown information of the preset time in a visual form.

[0059] Step S2013: When the countdown information of the control placement mechanism stops changing at the preset time, place the insulation board in the mold.

[0060] In one exemplary embodiment, step S103 includes step S1031.

[0061] As the mold moves from the downstream of the first production line to the upstream of the third production line, the curing mechanism controls the curing of the concrete in the mold to obtain a single-layer wall panel.

[0062] Step S103 includes step S1032.

[0063] Step S1032: When the second transfer mechanism transfers the mold from the downstream of the second production line to the upstream of the third production line, the second pouring mechanism is controlled to pour concrete for the second time in the mold and vibrate the concrete in the mold, and the curing mechanism is controlled to cure the concrete in the mold to obtain a multi-layer wall panel.
