Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and specifically relates to a modular cast-in-place concrete mold and its construction method. Background Technology

[0002] Beams and slabs are widely used in construction, mainly for floor slabs, roof slabs, balconies, canopies, stairs, foundations, and pool top slabs in residential buildings. Based on different construction methods, beams and slabs can be divided into two categories: cast-in-place and precast.

[0003] Currently, wooden formwork is commonly used in the manufacturing process of beams and slabs to support and shape them. However, traditional wooden formwork is prone to deformation after being exposed to direct sunlight, soaked in water, and reused more than four times, resulting in a short lifespan. Consequently, the turnover rate of wooden formwork is low, requiring remanufacturing, which wastes timber. Furthermore, wooden formwork needs to be customized according to the dimensions of the beams and slabs on the construction site. Summary of the Invention

[0004] The purpose of this invention is to provide a modular cast-in-place concrete mold and its construction method, which can be assembled and adjusted according to the size of beams and slabs to achieve rapid modularization, improve construction efficiency, and be applicable to the manufacture of beams and slabs of various sizes. At the same time, it can be recycled multiple times to improve turnover rate, reduce beam and slab manufacturing costs, and avoid environmental damage caused by excessive deforestation.

[0005] The technical solution adopted to solve the above-mentioned technical problems is as follows:

[0006] This invention provides a modular cast-in-place concrete mold having a first direction, a second direction, and a third direction that are perpendicular to each other. The modular cast-in-place concrete mold includes:

[0007] Multiple metal plates are respectively arranged along a first direction and a third direction. Each metal plate is L-shaped and extends along a second direction. Each metal plate has two mutually perpendicular forming surfaces. Every two adjacent metal plates overlap, and the two forming surfaces that are close to each other are stacked. All the forming surfaces together form a shaping surface for supporting the beam and shaping the beam. The shaping surface has a central symmetry line extending along a third direction.

[0008] The telescopic rod assembly has two connecting parts that can move relatively linearly. The telescopic rod assembly is provided between each pair of adjacent metal plates. The two connecting parts are respectively connected to the two adjacent metal plates. The telescopic rod assembly is provided with a plurality of them along a second direction.

[0009] The modular cast-in-place concrete mold provided by this invention has at least the following beneficial effects: Because each metal plate adopts an L-shaped structural design, multiple metal plates are arranged along a first direction and a third direction, and adjacent metal plates overlap sequentially. Therefore, the metal plates can be adapted to the 90° corners of the beam / slab, allowing the modular cast-in-place concrete mold to form a shaping surface for supporting and shaping the beam / slab. Furthermore, because each pair of adjacent metal plates is overlapped, they can move relatively linearly. Moreover, telescopic rod assemblies are provided between them. Therefore, on the construction site, the relative distance between adjacent metal plates can be adjusted according to the design dimensions of the beam / slab using the telescopic rod assemblies, and effectively fixed after adjustment. This makes the modular cast-in-place concrete mold suitable for manufacturing beams / slabs of various sizes. Simultaneously, the modular cast-in-place concrete mold is reusable, has a high turnover rate, and reduces the use of trees and damage to the natural environment.

[0010] As a further improvement to the above technical solution, the telescopic rod assembly includes an outer tube, an inner tube, and a threaded fastener. The outer tube is sleeved on the inner tube and can move linearly relative to the inner tube. The threaded fastener is disposed between the outer tube and the inner tube to lock the outer tube and the inner tube.

[0011] With this setup, after the outer and inner tubes are connected to the two adjacent metal plates respectively, the threaded fasteners can be loosened to drive the outer and inner tubes to move relative to each other, thereby adjusting the relative distance between the two adjacent metal plates. This allows the modular cast-in-place concrete mold to be adapted to beams and slabs of various sizes. After adjustment, the threaded fasteners are used to fix the outer and inner tubes together, so that the modular cast-in-place concrete mold remains fixed during the beam and slab manufacturing process.

[0012] As a further improvement to the above technical solution, the outer tube is provided with an elongated hole that extends along the length of the outer tube. The threaded fastener passes through the elongated hole and is threadedly connected to the inner tube. With this configuration, when adjusting the length of the telescopic rod assembly, the threaded fastener on the inner tube can be loosened, causing the inner tube to move linearly relative to the outer tube along with the threaded fastener. After the position is adjusted, the threaded fastener can be tightened, causing friction between the contact surfaces of the outer and inner tubes, thus firmly fixing the inner and outer tubes together.

[0013] As a further improvement to the above technical solution, elongated holes are provided on both opposite sides of the outer tube, extending along the length of the outer tube. The inner tube has through holes, and the threaded fastener passes sequentially through one of the elongated holes, the through hole, and the other elongated hole, and is connected to a fastening nut. This arrangement ensures that when the threaded fastener is tightened, the two opposite inner sides of the outer tube are forced into tight contact with the two opposite outer sides of the inner tube, generating sufficient friction to ensure that adjacent metal plates remain fixed during beam manufacturing.

[0014] As a further improvement to the above technical solution, one end of the outer tube is sleeved on one end of the inner tube, and the other end of the outer tube is connected to the metal plate, and the other end of the inner tube is also connected to the metal plate. With this configuration, when the outer tube and inner tube are fixedly connected to the two metal plates respectively, the outer tube can be sleeved on the inner tube, and the outer tube can move linearly relative to the inner tube, causing the two metal plates to move closer or further apart, thereby achieving modular cast-in-place concrete mold adapted to the manufacturing dimensions of beams and slabs.

[0015] As a further improvement to the above technical solution, in any of the metal plates, the telescopic rod assemblies located on the two molded surfaces are interconnected. This arrangement improves the stability of the telescopic rod assemblies on the metal plate, preventing them from easily shifting or even detaching from the metal plate. Simultaneously, it reinforces the corners of the metal plate, preventing it from easily bending or deforming.

[0016] As a further improvement to the above technical solution, an extension plate assembly is provided between any two adjacent metal plates. The extension plate assembly is overlapped with two adjacent forming surfaces and is equipped with the telescopic rod assembly. This arrangement allows for the addition of extension plate assemblies between corresponding metal plates according to the size of the beam / slab, enabling rapid adjustments so that the modular cast-in-place concrete mold can be matched to manufacture beams / slabs of the corresponding dimensions.

[0017] As a further improvement to the above technical solution, the extension plate assembly includes multiple extension plates, with each pair of adjacent extension plates overlapping and provided with the telescopic rod assembly. This arrangement allows the length of the extension plate assembly to be adjusted using the telescopic rod assembly, thereby enabling the extension plate assembly to adapt to the distance between adjacent metal plates and improving the versatility of the extension plate assembly.

[0018] As a further improvement to the above technical solution, multiple shaping surfaces are provided, and an extension plate assembly is provided between each pair of adjacent shaping surfaces. When manufacturing multiple beams and slabs continuously, with each shaping surface corresponding to one beam and slab, an extension plate assembly can be added between two shaping surfaces to ensure that all beams and slabs receive sufficient support and achieve excellent forming results.

[0019] Furthermore, the present invention also provides a construction method for a modular cast-in-place concrete mold, applicable to any of the above-described technical solutions, comprising the following steps:

[0020] Set up a support structure;

[0021] Assemble modular cast-in-place concrete molds;

[0022] The dimensions of the modular cast-in-place concrete mold shall be adjusted according to the dimensions of the beams and slabs.

[0023] Connect the modular cast-in-place concrete mold to the supporting structure;

[0024] Reinforcing bars are provided on the shaping surface of the modular cast-in-place concrete mold;

[0025] Concrete is poured onto the shaped surface.

[0026] The construction method of the modular cast-in-place concrete mold provided by the present invention has at least the following beneficial effects: Before each beam and slab is manufactured, the construction personnel assemble the modular cast-in-place concrete mold and adjust the size of the modular cast-in-place concrete mold according to the design size of the beam and slab so that the modular cast-in-place concrete mold can be adapted to the manufactured beam and slab. This can help improve construction efficiency and reduce the amount of wood consumed in each construction. Attached Figure Description

[0040] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0041] Reference Figures 1 to 8 The following are several embodiments of the modular cast-in-place concrete mold and its construction method of the present invention.

[0042] like Figures 1 to 6 As shown, this embodiment of the invention provides a modular cast-in-place concrete mold that can be used to manufacture beams and slabs 300. Construction workers can assemble and adjust the dimensions of the modular cast-in-place concrete mold according to the design dimensions of the beams and slabs 300, making it suitable for manufacturing beams and slabs 300 of various sizes. This improves the versatility of the modular cast-in-place concrete mold and enables rapid modularization on the construction site, which is beneficial for improving construction efficiency.

[0043] At the same time, compared with traditional wooden formwork, this modular cast-in-place concrete mold can be recycled multiple times, improving its turnover rate, which helps to reduce the manufacturing cost of beams and slabs and reduce the amount of trees used, thereby avoiding serious damage to the natural environment due to excessive logging.

[0044] The modular cast-in-place concrete mold structure includes multiple metal plates 100 and a telescopic rod assembly 200. The modular cast-in-place concrete mold has a first direction, a second direction, and a third direction, wherein the first direction is perpendicular to the second direction and perpendicular to the third direction, while the second direction is perpendicular to the third direction. In this embodiment, it is assumed that the first direction is the left-right direction, the second direction is the front-back direction, and the third direction is the up-down direction.

[0045] Each metal plate 100 is L-shaped, and the length of each metal plate 100 extends along the second direction. For example... Figure 1 and Figure 2 As shown, the metal plate 100 is an L-shaped plate, manufactured through a bending process. Each metal plate 100 has two forming surfaces, which are perpendicular to each other. In this embodiment, the thickness of the metal plate 100 is designed to be 0.5mm, and some of the metal plates 100 have dimensions of 500mm × 400mm, while others have dimensions of 400mm × 300mm.

[0046] It is understandable that the dimensions of the metal plate 100 can be set according to the actual situation, and no specific limitation is made here. The forming surface of the metal plate 100 is the surface of the metal plate 100 that contacts the beam plate 300.

[0047] All metal plates 100 are arranged along the first direction and the third direction, respectively. Each pair of adjacent metal plates 100 overlaps, causing their two adjacent forming surfaces to stack. This allows all forming surfaces to connect sequentially and form a shaping surface. The shaping surface supports the beam slab 300 and shapes it. Viewed along the front-back direction (i.e., the second direction), the shape of the shaping surface matches the shape of the beam slab 300. The shaping surface has a central symmetry line extending along the third direction (i.e., the vertical direction). In this embodiment, the shaping surface is symmetrical about the central symmetry line.

[0048] It is understood that the beam-slab 300 includes a beam 320 and a slab 310, with the beam 320 located below the slab 310. The beam 320 and slab 310 are integrally formed through a cast-in-place process and are T-shaped. During the cast-in-place molding process of the beam-slab 300, the forming surface can be in contact with the lower surface and sides of the beam 320 and the lower surface of the slab 310. When manufacturing a T-shaped beam-slab 300, the modular cast-in-place concrete mold includes four metal plates 100. Two metal plates 100 are located on the upper side and are symmetrically arranged about the central symmetry line of the beam-slab 300. The other two metal plates 100 are located on the lower side and are located on the left and right sides of the beam-slab 300. The four metal plates 100 are respectively set at the four 90° corners of the beam-slab 300, so that the forming surfaces of the four metal plates 100 are respectively in contact with the four surfaces of the beam-slab 300.

[0049] The telescopic pole assembly 200 has two connecting parts, which can move linearly relative to each other, thereby realizing the length extension and retraction function of the telescopic pole assembly 200. The telescopic pole assembly 200 is disposed between every two adjacent metal plates 100, one of which is fixedly connected to one connecting part of the telescopic pole assembly 200, and the other is fixedly connected to the other connecting part of the telescopic pole assembly 200.

[0050] Understandably, the telescopic rod assembly 200 serves to fix two adjacent metal plates 100, ensuring that the modular cast-in-place concrete mold remains stationary during the manufacture of the beam slab 300. Furthermore, the telescopic rod assembly 200 can be used to adjust the distance between the two adjacent metal plates 100, allowing the modular cast-in-place concrete mold to be dimensionally adjusted according to the beam slab 300 dimensions, eliminating the need for custom-made templates for manufacturing the beam slab 300, which is highly convenient.

[0051] like Figure 1 and Figure 2As shown, in this embodiment, when manufacturing a T-shaped beam slab 300, the modular cast-in-place concrete mold includes four metal plates 100. Therefore, the telescopic rod assembly 200 is provided in three sets, with each set located between two adjacent metal plates 100. For adjacent metal plates 100 on the upper and lower sides, the telescopic rod assembly 200 can increase or decrease the vertical distance between them. For adjacent metal plates 100 on the left and right sides, the telescopic rod assembly 200 can increase or decrease the horizontal distance between them.

[0052] It is understood that each group of telescopic pole assemblies 200 includes one or more telescopic pole assemblies 200. If each group of telescopic pole assemblies 200 includes multiple telescopic pole assemblies 200, then all the telescopic pole assemblies 200 are spaced apart along the second direction. In this embodiment, each group of telescopic pole assemblies 200 includes four telescopic pole assemblies 200, and they are arranged along the second direction at a certain interval.

[0053] Understandably, multiple metal plates 100 are arranged along the first and third directions respectively, with adjacent metal plates 100 overlapping one after another. Moreover, each metal plate 100 adopts an L-shaped structural design. Therefore, the metal plate 100 can be adapted to the 90° corner of the beam slab 300, so that the modular cast-in-place concrete mold can form a shaping surface for supporting the beam slab 300 and shaping the beam slab 300.

[0054] The two adjacent metal plates 100 are connected by an overlapping structure, allowing for relative linear movement. Furthermore, they are connected by a telescopic rod assembly 200. Therefore, on the construction site, workers can adjust the relative distance between the two adjacent metal plates 100 according to the design dimensions of the beam slab 300 using the telescopic rod assembly 200, and then effectively fix them after adjustment. This allows the modular cast-in-place concrete mold to be used for manufacturing beam slabs 300 of various sizes. At the same time, the modular cast-in-place concrete mold can be recycled and reused, with a high turnover rate, reducing the amount of trees used and the damage to the natural environment.

[0055] Specifically, such as Figure 6 As shown, the telescopic rod assembly 200 includes an inner tube 220, an outer tube 210, and a threaded fastener 230. The outer tube 210 has a hollow interior forming a cavity. The inner tube 220 extends into the cavity of the outer tube 210 and contacts the wall of the cavity, allowing the outer tube 210 to be fitted onto the inner tube 220. Furthermore, the inner tube 220 can move linearly relative to the outer tube 210. The threaded fastener 230 is disposed between the outer tube 210 and the inner tube 220, and its function is to lock the outer tube 210 and the inner tube 220 together.

[0056] It is understood that when a telescopic rod assembly 200 is provided between each pair of adjacent metal plates 100, one of the two adjacent metal plates 100 is fixedly connected to the outer pipe 210 and the other is fixedly connected to the inner pipe 220. When it is necessary to adjust the distance between the two adjacent metal plates 100, the construction personnel can loosen the threaded fasteners 230 and then drive the outer pipe 210 to move linearly relative to the inner pipe 220, thereby adjusting the distance between the two adjacent metal plates 100 and enabling the modular cast-in-place concrete mold to be adapted to beams and slabs 300 of various sizes.

[0057] After adjusting the relative positions of the two adjacent metal plates 100, the construction workers can use threaded fasteners 230 to fix the outer pipe 210 and the inner pipe 220 together, so that the modular cast-in-place concrete mold can remain fixed during the manufacturing process of the beam 300.

[0058] In some embodiments, the outer tube 210 is provided with an elongated hole 211, which communicates with the cavity and extends along the length of the outer tube 210. The inner tube 220 is provided with a threaded hole. The threaded portion of the threaded fastener 230 passes through the elongated hole 211 of the outer tube 210 and is screwed into the threaded hole of the inner tube 220, thus achieving a threaded connection between the threaded fastener 230 and the inner tube 220. After tightening the threaded fastener 230, the inner surface of the outer tube 210 and the outer surface of the inner tube 220 are in tight contact, generating sufficient friction to fix the outer tube 210 and the inner tube 220 together.

[0059] It is understandable that the inner tube 220 can be either solid or hollow. The threaded fastener 230 is a bolt. When adjusting the length of the telescopic rod assembly 200, the operator can loosen the threaded fastener 230 on the inner tube 220, and then drive the inner tube 220 to move the threaded fastener 230 in a straight line relative to the outer tube 210. At this time, the threaded fastener 230 moves along the length direction of the elongated hole 211. Then, after the relative positions of the outer tube 210 and the inner tube 220 are adjusted, the operator can tighten the threaded fastener 230, causing friction between the contact surfaces of the outer tube 210 and the inner tube 220, thus firmly fixing the inner tube 220 and the outer tube 210 together.

[0060] Alternatively, elongated holes 211 can be provided on other sides of the outer tube 210. Of course, it is not ruled out that if the inner tube 220 does not have a screw hole and the outer tube 210 has a screw hole instead of an elongated hole 211, a threaded fastener 230 can be screwed into the screw hole of the outer tube 210 and abut against the outer side of the inner tube 220, so that the threaded fastener 230 applies pressure to the inner tube 220, causing the outer side of the inner tube 220 to come into tight contact with the inner side of the outer tube 210.

[0061] In other embodiments, the outer tube 210 has elongated holes 211 on both opposite sides, which communicate with the cavity. The elongated holes 211 extend along the length of the outer tube 210. The inner tube 220 has a through hole, which can be a round hole. After the inner tube 220 is inserted into the cavity of the outer tube 210, the through hole communicates with the cavity. The construction worker passes the threaded portion of the threaded fastener 230 sequentially through one of the elongated holes 211 of the outer tube 210, the through hole of the inner tube 220, and the other elongated hole 211 of the outer tube 210. Then, a fastening nut is connected to the threaded portion of the threaded fastener 230.

[0062] Understandably, after the construction workers tighten the threaded fasteners 230, the two opposite inner surfaces of the outer tube 210 can tightly abut against the two opposite outer surfaces of the inner tube 220, so that the contact surfaces between the outer tube 210 and the inner tube 220 can generate a sufficiently large frictional force, thereby ensuring that the two adjacent metal plates 100 can remain stable during the manufacturing of the beam slab 300.

[0063] The telescopic rod assembly 200 with the above structure facilitates the quick assembly of modular cast-in-place concrete molds by construction personnel, resulting in high construction efficiency.

[0064] In some embodiments, both the outer tube 210 and the inner tube 220 are square tubes. This arrangement increases the contact area between the outer tube 210 and the inner tube 220, thereby enhancing the friction between them and ensuring that the two adjacent metal plates 100 remain stable under the locking action of the telescopic rod assembly 200.

[0065] The wall thickness of the outer tube 210 and the wall thickness of the inner tube 220 can be set to 0.8mm. The dimensions of the outer tube 210 can be 50mm×50mm×400mm, and the dimensions of the inner tube 220 can be 49.2mm×49.2mm×400mm.

[0066] Of course, it is possible that the outer tube 210 and the inner tube 220 can be round tubes or other shapes of tubes.

[0067] In some embodiments, one end of the outer tube 210 is sleeved on one end of the inner tube 220, the other end of the outer tube 210 is fixedly connected to the metal plate 100, and the other end of the inner tube 220 is fixedly connected to the metal plate 100.

[0068] It is understandable that, for two adjacent metal plates 100, in order to allow the two adjacent forming surfaces to be stacked, and for the outer tube 210 to be fitted onto the inner tube 220, there is a gap between the outer tube 210 and the metal plate 100, and there is a gap between the inner tube 220 and the metal plate 100.

[0069] After one end of the outer tube 210 and one end of the inner tube 220 are fixedly connected to the two metal plates 100 respectively, the other end of the outer tube 210 can be sleeved on the other end of the inner tube 220, so that the outer tube 210 can move linearly relative to the inner tube 220, causing the two metal plates 100 to move closer or further away from each other, thereby realizing the modular cast-in-place concrete mold adapted to the manufacturing size of the beam slab 300.

[0070] After the outer pipe 210 and inner pipe 220 are installed in their respective positions on the metal plate 100, the construction personnel determine the dimensions of the construction beam slab 300. Then, multiple metal plates 100 are assembled according to the dimensions of the beam slab 300. Next, the outer pipe 210 and inner pipe 220 are locked with threaded fasteners 230 to form a modular cast-in-place concrete mold.

[0071] like Figures 1 to 5 As shown, the metal plate 100 has two mounting surfaces: the first connecting surface 110 for mounting the outer tube 210, and the second connecting surface 120 for mounting the inner tube 220. It can be understood that the mounting surface and the forming surface are located on opposite sides of the metal plate 100. Figure 5 As shown, the first connecting surface 110 is positioned closer to the beam slab 300 than the second connecting surface 120.

[0072] In some embodiments, the outer tube 210 is spot-welded to the metal plate 100, and the inner tube 220 is spot-welded to the metal plate 100. This allows the telescopic rod assembly 200 to be securely mounted on the metal plate 100. Alternatively, a connecting block can be provided on the metal plate 100, and the outer tube 210 and inner tube 220 can be detachably connected to the connecting block via bolts.

[0073] In some embodiments, the metal plate 100 is an aluminum plate. In other embodiments, the metal plate 100 is a galvanized steel plate. Compared to aluminum plates, galvanized steel plates have higher strength, lower deflection, are less prone to deformation, and are cheaper. Therefore, the modular cast-in-place concrete mold is less prone to warping and deformation, and has a neat and bright appearance.

[0074] like Figures 1 to 4As shown, for any metal plate 100, the telescopic rod assemblies 200 located on the two forming surfaces are connected to each other, for example, by welding. This can improve the stability of the telescopic rod assembly 200 on the metal plate 100, prevent the telescopic rod assembly 200 from easily shifting or even detaching from the metal plate 100, and at the same time, it can reinforce the corners of the metal plate 100 without the need to set reinforcing ribs at the corners of the metal plate 100. This can effectively prevent the metal plate 100 from easily bending and deforming, thereby improving the overall structural stability of the modular cast-in-place concrete mold.

[0075] In some embodiments, such as Figure 7 and Figure 8 As shown, an extension plate assembly 400 is provided between any two adjacent metal plates 100. The opposite sides of the extension plate assembly 400 are respectively overlapped with the two adjacent forming surfaces, and a telescopic rod assembly 200 is provided between the forming surfaces and the extension plate assembly 400.

[0076] Understandably, construction workers can quickly adjust the modular cast-in-place concrete mold to fit the dimensions of the beam / slab 300 by adding an extension plate assembly 400 between two adjacent metal plates 100, based on the beam / slab 300's dimensions. For example, if the beam 320 has a larger vertical dimension, an extension plate assembly 400 can be placed between two adjacent metal plates 100 in the vertical direction, extending the modular cast-in-place concrete mold in the third direction. Similarly, if the beam 320 has a larger horizontal dimension, an extension plate assembly 400 can be placed between two adjacent metal plates 100 in the horizontal direction, extending the modular cast-in-place concrete mold in the first direction.

[0077] The extension plate assembly 400 comprises multiple extension plates 410. The extension plates 410 can be made of galvanized steel. Each pair of adjacent extension plates 410 is overlapped, and a telescopic rod assembly 200 is provided between each pair of adjacent extension plates 410. This arrangement allows the length of the extension plate assembly 400 to be adjusted using the telescopic rod assembly 200, thereby adapting the extension plate assembly 400 to the distance between adjacent metal plates 100 and improving the versatility of the extension plate assembly 400.

[0078] Understandably, if the extension plate assembly 400 includes two extension plates 410, the outer tube 210 and inner tube 220 of the telescopic rod assembly 200 are fixedly connected to the two extension plates 410 respectively. If the extension plate assembly 400 includes three extension plates 410, one of the outer tube 210 and the inner tube 220 can be placed on the middle extension plate 410, and the other can be placed on the extension plates 410 on both sides.

[0079] In some embodiments, multiple modular cast-in-place concrete molds are provided, resulting in multiple shaping surfaces. An extension plate assembly 400 is provided between each pair of adjacent shaping surfaces. When continuously manufacturing multiple beams and slabs 300, with each shaping surface corresponding to one beam and slab 300, an extension plate assembly 400 can be added between two shaping surfaces. The extension plate assembly 400 overlaps with two metal plates 100 on opposite sides in the first direction. A telescopic rod assembly 200 is also provided between the metal plates 100 and the extension plate assembly 400, ensuring that all beams and slabs 300 receive sufficient support and achieving excellent forming results.

[0080] Understandably, for each beam slab 300, a modular cast-in-place concrete mold is required. If multiple beam slabs 300 are arranged at intervals along the left and right directions, multiple modular cast-in-place concrete molds are needed. When the length of the slab 310 between two adjacent beam slabs 300 is large, one or more extension plates 410 can be added to the two adjacent metal plates 100 on the left and right sides, and telescopic rod assemblies 200 can be installed between the two adjacent extension plates 410 and between the metal plate 100 and the adjacent extension plates 410. At this time, the extension plates 410 provide support for the slab 310 in the beam slab 300 structure, such as... Figure 8 As shown.

[0081] Furthermore, embodiments of the present invention also provide a construction method for a modular cast-in-place concrete mold, used for any of the modular cast-in-place concrete molds described in the above embodiments, the construction method comprising the following steps:

[0082] Step S1: Set up the support structure.

[0083] Step S2: Assemble the modular cast-in-place concrete mold.

[0084] Step S3: Adjust the dimensions of the modular cast-in-place concrete mold according to the dimensions of the beam 300.

[0085] Step S4: Connect the modular cast-in-place concrete mold to the supporting structure.

[0086] Step S5: Set reinforcing bars on the shaping surface of the modular cast-in-place concrete mold.

[0087] Step S6: Pour concrete onto the shaped surface.

[0088] Understandably, the supporting structure serves to support the modular cast-in-place concrete mold and the beams and slabs 300 on it. The supporting structure can be supported by wooden or metal pipes. In this embodiment, the supporting structure can be a steel pipe and fastener scaffold, facilitating on-site assembly and disassembly by construction workers.

[0089] Before erecting the supporting structure, a modular cast-in-place concrete mold of appropriate specifications can be selected according to the dimensions of the beam 300. In each specification of modular cast-in-place concrete mold, the dimensions of the metal plates 100 are different. The forming surface of each metal plate 100 is welded with an outer tube 210 or inner tube 220 from the telescopic rod assembly 200 to form a mold module, facilitating the rapid assembly of all mold modules into a modular cast-in-place concrete mold by construction personnel.

[0090] Construction workers measured, positioned, and laid out lines on the floor according to the dimensions and locations of the beams and slabs in the 300mm design drawings.

[0091] After the support structure was erected, the construction workers adjusted the top support of the support structure according to the data such as the bottom elevation of the beam and the bottom elevation of the slab in the beam and slab design drawings.

[0092] Construction workers can assemble all the mold modules on an open ground. By overlapping and connecting two adjacent metal plates 100 and inserting the outer tube 210 and inner tube 220 of the telescopic rod assembly 200, a modular cast-in-place concrete mold can be assembled.

[0093] Before each beam slab 300 is manufactured, the construction workers assemble the modular cast-in-place concrete mold. Then, according to the design dimensions of the beam slab 300, the size of the modular cast-in-place concrete mold is adjusted by operating the telescopic rod assembly 200 to obtain a modular cast-in-place concrete mold that meets the dimensions of the beam slab 300 required by the design drawings. This ensures that the modular cast-in-place concrete mold can be adapted to the manufactured beam slab 300, which helps to improve construction efficiency and reduce the amount of timber consumed in each construction.

[0094] Since the outer tube 210 and inner tube 220 of the telescopic rod assembly 200 are fixedly connected to the metal plate 100, the outer tube 210 and inner tube 220 can be separated by loosening the threaded fastener 230, allowing the two adjacent metal plates 100 to be separated. When assembling the cast-in-place concrete mold, the two adjacent metal plates 100 are overlapped, and the inner tube 220 is inserted into the outer tube 210. Then, the outer tube 210 and inner tube 220 are connected using the threaded fastener 230.

[0095] After the modular cast-in-place concrete mold is assembled and adjusted, the assembled modular cast-in-place concrete mold is hoisted onto the supporting structure and fixed using lifting equipment, so that the modular cast-in-place concrete mold can be stably erected on the supporting structure and can receive the support provided by the supporting structure.

[0096] Because the dimensions of the beam 300 in the second direction are larger than the dimensions of each modular cast-in-place concrete mold in the second direction, construction workers need to assemble multiple modular cast-in-place concrete molds along the second direction of the beam 300. Furthermore, based on the dimensions of the plate 310 in the first direction, an extension plate assembly 400 is added, allowing the extension plate assembly 400 to connect with the adjacent metal plate 100.

[0097] After assembling the modular cast-in-place concrete mold according to the beam 300 dimension, the construction workers treat the gaps between every two adjacent metal plates 100 and between the metal plate 100 and the extension plate 410, applying leak-proof tape to the gaps to prevent concrete leakage. Additionally, the construction workers can install stress monitoring equipment on the modular cast-in-place concrete mold to monitor its stress levels.

[0098] Before pouring concrete into the modular cast-in-place concrete mold, the corresponding reinforcing bars are first installed on the mold to ensure that the manufactured beam slab 300 has a strong load-bearing capacity. Specifically, construction workers tie the reinforcing bars of the beam slab 300 and embed electromechanical pipelines in the modular cast-in-place concrete mold.

[0099] Construction workers can apply concrete release agent to the shaped surface of the metal plate 100. Similarly, they can apply concrete release agent to the surface of the extension plate 410 that contacts the beam 300 to avoid the problem of difficult disassembly of the modular cast-in-place concrete mold due to the metal plate 100 and the extension plate 410 being firmly bonded to the concrete.

[0100] Then, construction workers can pour concrete into the modular cast-in-place concrete molds. Next, the concrete components are cured, and the stress on the modular cast-in-place concrete molds and concrete components is monitored.

[0101] After beam 300 is manufactured, the modular cast-in-place concrete mold and supporting structure are dismantled sequentially. Once the dismantling conditions are met, the construction workers first remove the modular cast-in-place concrete mold. The extension plate assembly 400 is removed first, followed by the metal plate 100.

[0102] Specifically, when disassembling the extension plate assembly 400, first use a rubber rod to loosen the extension plate 410, allowing it to slightly detach from the concrete. Loosen and remove the threaded fasteners 230 on the extension plate 410, and disassemble each extension plate 410 of the entire extension plate assembly 400 one by one. Then, slowly lower the extension plate 410 to the ground and transport it to an open area. Similarly, the metal plate 100 is disassembled following the same steps as the extension plate assembly 400. Moreover, before disassembly, the top support of the supporting structure needs to be loosened.

[0103] After the modular cast-in-place concrete molds are dismantled, the construction workers can remove the supporting structure and clean up the site.

[0104] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
