Description

Technical Field

[0001] This invention relates to the field of building material production technology, and in particular to a multi-cavity vertical mold for steam curing and a production process for ALC exterior wall panels. Background Technology

[0002] Currently, ALC exterior wall panels are mainly assembled from ALC strip panels, with the main assembly methods being vertical and horizontal assembly. According to the production process of ALC strip panels, the production of strip panels is mainly divided into two forms: (1) The cavity box mold is placed horizontally on the production line, foamed concrete is poured, steel mesh is inserted, and after constant temperature static curing, the cured mold is transferred to the cutting area for mold separation and blank cutting. Then the cut blank is sent to the autoclave for autoclaving by a transfer car; (2) The strip panel vertical mold is assembled on the production line, steel mesh is inserted and the mesh position is fixed, then foamed concrete is poured, and after autoclaving, the mold is removed to complete the strip panel production.

[0003] There are many technical drawbacks to assembling large panels using ALC strip panels, such as: (1) poor overall integrity of the strip panel assembly, requiring a special design to assemble the strip panels with structural steel, resulting in a large consumption of connectors and wall purlin steel; (2) numerous joints, leading to potential cracking and leakage, and poor thermal insulation, requiring special joint treatment measures to address the seepage prevention and thermal insulation issues of the assembled large panels. Therefore, existing assembled large panels suffer from complex construction processes, significant safety hazards, and poor economic benefits. How to improve the manufacturing process of ALC exterior wall panels, increase the utilization rate of prefabrication yard work surfaces, achieve integrated wall panel forming and maintenance, further optimize the production process of ALC exterior wall panels, and reduce production costs are urgent issues to be addressed. Summary of the Invention

[0004] To overcome the aforementioned shortcomings of existing methods that use ALC strips to assemble ALC exterior wall panels, the technical problem to be solved by this invention is to provide a multi-cavity vertical mold for steam curing ALC exterior wall panels and an ALC exterior wall panel production process.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A multi-cavity vertical mold for steam curing includes multiple steam curing chambers vertically arranged on a base plate. The steam curing chambers are arranged side by side with intervals, and side templates are provided between the corresponding sides of two adjacent steam curing chambers. The steam curing chambers are hollow, and multiple crisscrossing vertical and horizontal partitions are provided inside the cavity to divide the internal cavity of the steam curing chamber into multiple steam curing chambers. The vertical and horizontal partitions are provided with multiple air holes to connect all the steam curing chambers together. The side of the steam curing chamber is provided with an air inlet and an air outlet that are respectively connected to the first and last steam curing chambers of the multiple steam curing chambers connected together.

[0007] Furthermore, the pores on the vertical and horizontal partitions allow steam to flow in a horizontal or vertical S-shaped direction within each steam curing chamber.

[0008] Furthermore, the steam curing box plate has strip-shaped frames on both sides, and the side template is connected to the strip-shaped frames of two adjacent steam curing box plates through a connecting structure;

[0009] The connection structure consists of through holes on both sides of the strip frame and the side template, and bolt and nut kits that are inserted and fixed in the corresponding through holes;

[0010] Alternatively, the connection structure consists of through holes on both sides of the strip frame and the side template, and U-shaped snap fasteners inserted into the corresponding through holes. One end of the U-shaped snap fastener is inserted into the through hole through an L-shaped rotating rod, and the other end is used to snap the edges of the strip frame and the side template together through a U-shaped buckle.

[0011] Alternatively, the connecting structure may consist of matching dovetail grooves and dovetail protrusions respectively disposed on the strip frame and the side template and arranged along the extension direction of their mating surfaces.

[0012] Furthermore, the base plate is provided with a plurality of strip-shaped protruding tenons arranged in parallel, the steam curing box plate is disposed in the gap between adjacent protruding tenons, and the top of the side template is the same as the top contour of the protruding tenons; it also includes a concave tenon that can slide along the gap between the tops of two adjacent steam curing box plates, the bottom of the concave tenon matching the top contour of the protruding tenon.

[0013] Furthermore, the tenon has a hollow U-shaped cross section, and both ends of the tenon have through holes at the bottom. The base plate also has corresponding mounting holes. One end of the connector used to fix the tenon passes through the corresponding through hole and mounting hole, and the other end rotates into the tenon and abuts against the top of the tenon.

[0014] Furthermore, both ends of the base plate are provided with clamping mechanisms. The clamping mechanisms include hydraulic rods and mutually hinged baffles and mounting plates. The mounting plates are fixed on the base plate, and the hydraulic rods are connected between the baffles and the mounting plates. Under the action of the hydraulic rods, the baffles of the two clamping mechanisms are respectively pressed against the sides of the first and last two steam curing chambers among the multiple steam curing chambers arranged side by side.

[0015] Furthermore, the lower end of the hydraulic rod is fixed to the mounting plate by a first rotating support, and the upper end is slidably connected to the vertical groove on the baffle by a second rotating support.

[0016] Furthermore, it also includes a support plate and a guide rail, with the base plate set on the support plate and rollers at the bottom of the support plate that can roll along the guide rail.

[0017] Furthermore, it also includes a steam generator, which is equipped with a steam pipe connected to the air inlet of the steam curing chamber plate.

[0018] The process for producing ALC exterior wall panels using the above-mentioned multi-cavity vertical mold steam curing mold includes the following steps:

[0019] Step 1: Assemble the mold. First, place the steam curing box panels at intervals on the base plate, then install and fix the side templates. The cavity formed by two adjacent steam curing box panels and two side templates is the casting cavity of the ALC exterior wall panel.

[0020] Step 2: Rebar tying. Tie the rebars on the outside, then place them into the casting cavity and fix them in place.

[0021] Step 3: Pour concrete. Use concrete pouring equipment to fill the pouring cavity with concrete until it is full, and then smooth or shape the surface of the concrete.

[0022] Step 4: Curing. First, allow the concrete slab to stand still for a period of time. Then, use a steam pipe to introduce steam into the air inlet on the steam curing chamber plate to steam cure the concrete slab.

[0023] Step 5: Demolding and warehousing. After curing, remove the steam curing box panels and concrete panels from one side to the other, send the concrete panels to the warehouse, and then reassemble the mold for the next batch of production.

[0024] The beneficial effects of this invention are:

[0025] 1. By using a multi-cavity steam curing box and side formwork as the pouring mold for concrete slabs, the pouring and curing of concrete slabs can be achieved in one go, resulting in finished ALC exterior wall panels. Compared with existing production processes, this avoids the hassle of cutting and steam curing, and greatly improves the production efficiency of ALC exterior wall panels.

[0026] 2. The mold is placed vertically, which effectively saves the area occupied by the prefabrication site. The mold is lightweight, has a long service life, and can be reused. The overall casting and steam curing are convenient and economical. At the same time, the mold is easy to install and disassemble. The lifting device can be used to hoist each template structure onto the base plate and splice them in sequence to form a module that can produce 5-10 wall panels at the same time, with a large number of panels produced at one time.

[0027] 3. The ALC exterior wall panels produced by this mold can be directly used for on-site exterior wall panel construction and installation. It can effectively overcome the defects of existing strip panels, such as complex assembly, large amount of steel required, poor waterproofing and thermal insulation performance, saving installation time and material costs, and has high safety.

Detailed Implementation

[0038] The invention will be further described below with reference to the accompanying drawings.

[0039] It should be noted that if this invention uses directional terms such as up, down, left, right, front, and back, these are for describing the relative positions of components and are not specific references to the absolute positions of related components or the relationships between them. They are only used to explain the relative positional relationships and movements of components in a specific posture. If the specific posture changes, the directional indication will also change accordingly. If this invention uses terms related to quantity such as "many," "multiple," or "several," these specifically refer to two or more.

[0040] like Figure 1 , Figure 2 As shown, the multi-cavity vertical mold for steam curing of the present invention includes multiple steam curing chambers 1 vertically arranged on a base plate 2. The multiple steam curing chambers 1 are arranged side by side with intervals, and side templates 3 are provided between the corresponding sides of two adjacent steam curing chambers 1. The cavity formed by two adjacent steam curing chambers 1 and the two side templates 3 on both sides is the casting cavity of the ALC exterior wall panel. The steam curing chamber 1 has a hollow structure, and multiple vertical partitions 11 and horizontal partitions 12 are provided in the cavity, dividing the internal cavity of the steam curing chamber 1 into multiple steam curing chambers 13. Multiple air holes 14 are provided on the vertical partitions 11 and horizontal partitions 12, connecting all the steam curing chambers 13 together. The side of the steam curing chamber 1 is provided with an air inlet 15 and an air outlet 16 respectively connected to the first and last steam curing chambers 13 of the multiple steam curing chambers 13 connected together. The multiple vents 14 connecting all the steam curing chambers 13 in series means that after steam enters from the inlet 15, it can pass through all the steam curing chambers 13 along a single path via the vents 14, and then exit from the outlet 16. For example, vents 14 can be provided on all the vertical partitions 11, and vents 14 can be provided on the transverse partition 12 of the last steam curing chamber 13 in the odd-numbered row, and on the transverse partition 12 of the first steam curing chamber 13 in the even-numbered row. This allows the steam to flow in a vertical S-shaped path through each steam curing chamber 13. Alternatively, the steam curing chamber plate 1 can be rotated 90° to form a horizontal S-shaped path.

[0041] This invention uses a steam curing chamber 1 to replace the existing casting template. It serves both as a casting template and, by introducing steam into the chamber 1, achieves a similar curing effect to traditional steam curing through heat conduction. Considering both the structural strength and heat conduction efficiency of the steam curing chamber 1, it is best made of stainless steel or aluminum alloy, with the edges sealed using welding or sand casting processes. The spacing between the vertical partitions 11 and the horizontal partitions 12 is preferably controlled at 300-600mm. Two to three air holes 14 are provided between two adjacent steam curing chambers 13 to ensure that steam can remain and accumulate in each chamber, while effectively reducing wear on the partitions during steam curing and extending their service life.

[0042] To facilitate the assembly of the steam curing chamber plate 1 and the side template 3, strip-shaped frames 17 are provided on both sides of the steam curing chamber plate 1. The side template 3 is connected to the strip-shaped frames 17 of two adjacent steam curing chamber plates 1 through a connecting structure. The strip-shaped frames 17 are arranged around the side edge of the steam curing chamber plate 1, and the side template 3 needs to have flanged structures on both sides to facilitate abutting against the strip-shaped frames 17 and connecting the two through connectors. Regarding the specific form of the connecting structure, this invention provides three solutions:

[0043] The first type is, such as Figure 3 As shown, the connection structure consists of through holes on both sides of the strip frame 17 and the side template 3, and bolt and nut kits 31 that are fixed in the corresponding through holes. The connection is made by bolts and nuts, which has high connection strength, but the installation process is a little more troublesome.

[0044] The second type is, such as Figure 4 As shown, the connecting structure consists of through holes on both sides of the strip frame 17 and the side template 3, and U-shaped snap fasteners 32 inserted into the corresponding through holes. The specific structure of the U-shaped snap fasteners 32 is as follows: Figure 5 As shown, during installation, first insert the L-shaped rotating rod 321 at one end of the U-shaped mold buckle 32 into the through hole, and then rotate the U-shaped mold buckle 32 so that the U-shaped buckle 322 at the other end is engaged with the flange of the strip frame 17 and the side template 3, thereby realizing the connection between the strip frame 17 and the side template 3. This connection structure is more convenient for installation and disassembly than bolt and nut connection.

[0045] The third type is, such as Figure 6 As shown, the connecting structure consists of matching dovetail grooves 33 and dovetail protrusions 34, respectively arranged on the strip frame 17 and the side template 3, and extended along the mating surface of the two. The side template 3 is assembled using a sliding fit between the dovetail grooves 33 and the dovetail protrusions 34, which is simpler and more convenient. The side template 3 can be installed and removed by lowering and pulling it upwards.

[0046] Considering structural stability, ALC exterior wall panels generally cannot be made too large. In large-area exterior wall assembly, splicing of ALC exterior wall panels is still necessary. Therefore, to facilitate the splicing and positioning of ALC exterior wall panels and reduce splicing gaps, butt joint structures need to be installed at the edges of the ALC exterior wall panels. The solution adopted in this invention is as follows: Figure 7 As shown, multiple strip-shaped tenons 4 are arranged side by side on the base plate 2. The steam curing box plate 1 is positioned within the gap between adjacent tenons 4. The top of the side template 3 has the same top contour as the tenons 4. It also includes a recessed tenon 5 that can slide along the gap between the tops of two adjacent steam curing box plates 1. The bottom of the recessed tenon 5 matches the top contour of the tenons 4, as shown. Figure 9As shown. The tenon 4 is set at the bottom of the pouring cavity of the concrete slab, forming a groove at the bottom of the concrete slab after pouring. The top tenon 5 can slide along the gap between the tops of the two steam curing box panels 1 during the initial setting stage of the concrete, thereby scraping out a raised strip on the top of the concrete slab that matches the groove of the bottom plate. During assembly, the raised strip can be inserted into the groove to achieve the splicing of the ALC exterior wall panels.

[0047] Specifically, such as Figure 8 As shown, to facilitate the installation and positioning of the tenon 4, the tenon 4 has a hollow U-shaped cross-section. Both ends of the tenon 4 have through holes at their bottoms, and the base plate 2 also has corresponding mounting holes. One end of the connector 41, used to fix the tenon 4, passes through the corresponding through hole and mounting hole, while the other end rotates into the tenon 4 and abuts against the top of the tenon 4. Two through holes can be provided at each end of the tenon 4 to ensure accurate connection and positioning. The specific structure of the connector 41 is shown in the figure. The connector 41 is hidden and fixed inside the cavity of the tenon 4, without affecting the pouring of the concrete slab. The gap between two adjacent tenons 4 can be approximately equal to the width of the steam curing box plate 1, so as to provide positioning for the installation of the steam curing box plate 1.

[0048] The top of the side template 3 has the same outline as the top of the tenon 4, which is to facilitate its mating with the tenon 5 and avoid interference with the movement of the tenon 5. Additionally, as... Figure 9 As shown, to facilitate the sliding of the tenon 5 and to scrape a stable raised strip structure on the top of the concrete slab, stepped grooves 51 are provided at both ends of the tenon 5, which can overlap the top of the steam curing box plate 1 on both sides. By using the stepped grooves 51 at both ends to lock onto the top of the steam curing box plate 1, the sliding stability of the tenon 5 can be ensured. A handle 52 is provided at the top of the tenon 5, which workers can hold to move the tenon 5, improving the convenience of use.

[0049] For some small molds, stable placement can be achieved by the multiple parallel-arranged curing chamber plates 1 themselves, as they are connected by side templates 3. However, for larger molds, additional structures are required for support. Therefore, this invention provides clamping mechanisms 6 at both ends of the base plate 2, such as... Figure 7As shown, the clamping mechanism 6 includes a hydraulic rod 63 and a baffle 61 and a mounting plate 62 that are hinged to each other. The mounting plate 62 is fixed to the base plate 2 by bolts or other means. The hydraulic rod 63 is connected between the baffle 61 and the mounting plate 62. Under the action of the hydraulic rod 63, the baffles 61 of the two clamping mechanisms 6 press against the sides of the first and last two steam curing chamber plates 1 arranged side by side. Furthermore, in order to enable the hydraulic rod 63 to rotate with the baffle 61, the lower end of the hydraulic rod 63 is fixed to the mounting plate 62 by a first rotating support 64, and the upper end is slidably connected to the vertical groove 66 on the baffle 61 by a second rotating support 65. When assembling the mold, first control the clamping mechanism 6 at one end to extend the hydraulic rod 63 so that the baffle 61 is in a vertical state. Then place the first steam curing box plate 1 against the baffle 61, and then place the remaining steam curing box plates 1 in sequence and connect the side templates 3. After all the steam curing box plates 1 are installed, start the clamping mechanism 6 at the other end so that the baffle 61 presses on the last steam curing box plate 1, thereby clamping and fixing all the steam curing box plates 1.

[0050] To facilitate the transfer of molds and concrete slabs, this invention also includes a support plate 7 and a guide rail 8. The base plate 2 is mounted on the support plate 7, and the bottom of the support plate 7 is equipped with rollers 71 that can roll along the guide rail 8. The support plate 7 increases the rigidity and load-bearing capacity of the bottom, ensuring that the top will not deform even with the support of at least four rollers 71. In actual production, multiple sets of molds can be set up on the track 8, and multiple workstations can be set up for different processes, thereby realizing assembly line operation and further improving production efficiency.

[0051] To achieve steam curing, the present invention also includes a steam generator 9, which is equipped with a steam pipe 91 connected to the air inlet 15 of the steam curing chamber plate 1. Each steam curing chamber plate 1 corresponds to one steam pipe 91. The steam exiting from the air outlet 16 of the steam curing chamber plate 1 can be directly discharged into the air, or a return steam pipe can be installed to collect the steam and send it back to the steam generator 9.

[0052] The process for producing ALC exterior wall panels using the aforementioned multi-cavity vertical mold steam curing mold mainly includes the following steps:

[0053] Step 1: Assemble the mold. First, place the steam curing box 1 at intervals on the base plate 2. Then, install and fix the side templates 3. The cavity formed by two adjacent steam curing box 1s and two side templates 3 is the casting cavity of the ALC exterior wall panel.

[0054] Step 2: Rebar tying. Tie the rebars on the outside, then place them into the casting cavity and fix them in place.

[0055] Step 3: Pour concrete. Use concrete pouring equipment to fill the pouring cavity with concrete until it is full, and then smooth or shape the surface of the concrete.

[0056] Step 4: Curing. First, allow the concrete slab to stand still for a period of time. Then, use a steam pipe to introduce steam into the air inlet 15 on the steam curing chamber plate 1 to steam cure the concrete slab.

[0057] Step 5: Demolding and warehousing. After curing, remove the steam curing box panel 1 and the concrete panel from one side to the other, send the concrete panel to the warehouse, and then reassemble the mold for the next batch of production.

[0058] If tenons 4 and tenons 5 are used, tenons 4 need to be installed before hoisting the steam curing box panels 1. After the concrete has initially set, tenons 5 need to be slid along the gap between the tops of the two steam curing box panels 1 to scrape out a raised structure on the top of the concrete panel, identical to that of tenons 4. This production process is simple and convenient. Compared with the current production process, the forming of the exterior wall panels and steam curing are both completed within the mold, saving time and cost and improving production efficiency.
