Abstract
Description
Technical Field
[0001] This application relates generally to the technical field of modular concrete buildings, and more specifically to a casting mold and demolding method for a concrete building module. Background Technology
[0002] Modular buildings are building structural systems assembled from multiple box-like structural units (i.e., building modules). Building modules can be formed from reinforced concrete. Modular construction typically utilizes standardized factory production, therefore steel structures are commonly used as mold materials, and these can be reused to meet the demands of standardized production. Good mold design and molding processes are crucial for the successful fabrication of concrete modules.
[0003] The molds used in related technologies are typically designed for common regular hexahedral box structures. In the fabrication of modular concrete building modules, the inner mold is formed using an inner mold. First, the inner mold is installed and fixed, then concrete is poured. After the concrete solidifies, the inner mold is demolded and removed, completing the cast-in-place concrete module. The outer mold is usually demolded by pushing it outwards, while the inner mold is demolded manually by entering the concrete module. For other structural forms of concrete building modules, manual demolition is difficult and it's hard to ensure the integrity of the concrete surface inside the box girder. Currently, there are no good mold designs or demolding methods, resulting in difficulties and low efficiency in demolding.
[0004] Therefore, there is a need to provide a casting mold and demolding method for concrete building modules to at least partially solve the above problems. Summary of the Invention
[0005] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This summary section is not intended to limit the key and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.
[0006] To at least partially solve the above problems, a first aspect of this application provides a casting mold for a concrete building module, the casting mold comprising:
[0007] A base frame, wherein a bottom module is provided on the base frame, the bottom module protruding from the top surface of the base frame and disposed thereon, and the base frame forming a recessed space in the area where the bottom module is not provided; and
[0008] A first inner mold assembly, comprising at least two inner modules connected to form the first inner mold of the concrete building module, wherein the at least two inner modules include:
[0009] A first inner module, detachably connected to the bottom module, the first inner module having a first connecting ramp; and
[0010] A second inner module is detachably connected to the first inner module. The second inner module has a second connecting ramp in a direction perpendicular to the base frame, and the lower end of the second connecting ramp is closer to the first inner module than the upper end of the second connecting ramp.
[0011] When the second inner module is connected to the first inner module, the second connecting inclined surface and the first connecting inclined surface are in contact, and the second inner module is suspended above the base frame. When the second inner module and the first inner module are disassembled, the second inner module can move downward relative to the first inner module into the sunken space.
[0012] According to this solution, when the first inner mold assembly is dismantled, the second inner module can slide down into the sunken space after being disconnected from the first inner module, thereby improving the dismantling efficiency of the first inner mold assembly.
[0013] Optionally, the bottom end of the second inner module extends partially into the sunken space, and the lower end of the second inner module is fitted to the side surface of the bottom module.
[0014] According to this plan, the second inner module can be directly lowered into the sunken space.
[0015] Optionally, the bottom end of the second inner module is provided with a positioning element, which is detachably connected to the bottom module.
[0016] According to this scheme, the second inner module is connected to the bottom module through a positioning component, which can play a positioning role.
[0017] Optionally, the base frame is further provided with a first support member, which is located within the sunken space.
[0018] When the second inner module and the first inner module are disassembled, the first support member is used to support the second inner module.
[0019] According to this plan, the first support component can play a supporting and buffering role, preventing the second inner module from sliding down and violently colliding with the base frame, thus preventing damage to the base frame.
[0020] Optionally, the bottom module is provided with a first connecting ear plate, which is configured to extend horizontally from the bottom module into the sunken space;
[0021] The bottom end of the first inner module is provided with a second connecting ear plate that matches the first connecting ear plate. The first connecting ear plate and the second connecting ear plate are detachably connected by a locking member.
[0022] According to this solution, the first inner module and the bottom module are connected by the first connecting ear plate and the second connecting ear plate. Furthermore, the second connecting ear plate can increase the contact area between the first inner module and the bottom module, so that the first inner module can be stably supported and connected to the bottom module.
[0023] Optionally, the first connecting ear plate is also connected to a second supporting member, which is located within the sunken space and is connected to the base frame.
[0024] According to this scheme, the second support member is connected between the first connecting lug and the base frame, which serves to strengthen the support.
[0025] Optionally, the first inner module includes a negative corner or two adjacent negative corners; and / or
[0026] The second inner module includes a negative corner or two adjacent negative corners.
[0027] According to this scheme, the inside corner is formed by the first inner module and / or the second inner module, so that the connection position of the first inner module and the second inner module avoids the inside corner position, which facilitates the connection of the first inner mold assembly and also facilitates the concrete pouring at the inside corner position.
[0028] Optionally, the casting mold further includes:
[0029] Outer mold, which is detachably connected to the bottom module; and
[0030] The second inner mold assembly includes a second inner mold and a connecting component. The second inner mold is connected to the outer mold via the connecting component, such that the second inner mold is suspended above the bottom module.
[0031] The second inner mold is composed of at least two inner modules joined together, and the at least two inner modules include:
[0032] The third inner module is fixedly connected to the outer mold via the connecting component; and
[0033] A fourth inner module is detachably connected to the third inner module, and the splicing surface of the third inner module and the fourth inner module is constructed as an inclined surface so that when the third inner module and the fourth inner module are disassembled, one of the third inner module and the fourth inner module can slide relative to the other along the splicing surface.
[0034] According to this scheme, after concrete pouring, the area partially enclosed by the first inner mold component, the bottom module, the outer mold, and the second inner mold component can form a concrete module building with a top opening and a bottom hollow; after concrete pouring, the area partially enclosed by the second inner mold component, the bottom module, the outer mold, and the first inner mold component can form a concrete module building with a bottom plate and a top opening.
[0035] Optionally, the second inner mold assembly further includes a third support member disposed inside the box structure of the second inner mold.
[0036] According to this scheme, the third support component can prevent the second inner mold from bulging, improve the pouring effect of the concrete building module, and prevent the second inner mold from deforming and becoming difficult to demold.
[0037] The second aspect of this application provides a demolding method for a casting mold of the concrete building module described in the first aspect of this application, the demolding method comprising the following steps:
[0038] Disassemble the second inner module and the first inner module, so that the second inner module separates from the first inner module under the action of gravity and slides downward into the sunken space;
[0039] Disassemble the first inner module and the bottom module.
[0040] According to this scheme, the area formed by the bottom module, the first inner mold component, and the outer mold after being enclosed can form a concrete building module with a top opening and a hollow bottom after concrete pouring. By forming a sunken space on the base frame, the first inner mold component can be demolded more effectively.
[0041] Optionally, the casting mold for the concrete building module further includes an outer mold and a second inner mold assembly. The outer mold is detachably connected to the bottom module. The second inner mold assembly includes a second inner mold and a connecting assembly. The second inner mold is connected to the outer mold through the connecting assembly, so that the second inner mold is suspended above the bottom module.
[0042] The second inner mold is a box structure with an upward opening. The second inner mold is composed of at least two inner modules spliced together. The at least two inner modules include a third inner module and a fourth inner module. The third inner module is fixedly connected to the outer mold through the connecting component. The fourth inner module is detachably connected to the third inner module. The splicing surface of the third inner module and the fourth inner module is constructed as an inclined surface.
[0043] The demolding method further includes the following steps:
[0044] Disassemble the fourth inner module and the third inner module;
[0045] Disassemble the third inner module and the outer mold.
[0046] According to this scheme, after concrete pouring, the area enclosed by the second inner mold component, the bottom module, the outer mold, and the first inner mold component can form a concrete building module with a top opening. Therefore, the second inner mold component can be disassembled. Attached Figure Description

[0082] The specific embodiments of this application will be described in more detail below with reference to the accompanying drawings, which illustrate representative embodiments of this application and are not intended to limit this application.
[0083] like Figures 1 to 13 As shown, this is a casting mold 100 for a concrete building module according to an embodiment of this application.
[0084] The casting mold 100 includes a base frame 110 and a first inner mold assembly 120. The base frame 110 is provided with a bottom module 111, which protrudes from the top surface of the base frame 110 and is attached to the base frame 110. A recessed space 112 is formed in the area of the base frame 110 where the bottom module 111 is not located. In other words, the bottom module 111 divides the base frame 110 into the recessed space 112.
[0085] The first inner mold assembly 120 includes at least two inner modules, which are connected to form a first inner mold for a concrete building module. Specifically, the at least two inner modules include a first inner module 121 and a second inner module 122. The first inner module 121 is detachably connected to the base module 111 and has a first connecting ramp 121b. The second inner module 122 is detachably connected to the first inner module 121. The second inner module 122 has a second connecting ramp 122b, and along a direction perpendicular to the base frame 110 (i.e., the height direction D2 of the concrete building module), the lower end of the second connecting ramp 122b is closer to the first inner module 121 than the upper end of the second connecting ramp 122b.
[0086] When the second inner module 122 is connected to the first inner module 121, the second connecting inclined surface 122b and the first connecting inclined surface 121b are in contact, and the second inner module 122 is suspended above the base frame 110. When the second inner module 122 and the first inner module 121 are disassembled, the second inner module 122 can move downward relative to the first inner module 121 into the sunken space 112.
[0087] It is understood that the first inner mold assembly 120 is suitable for casting bottomless building modules. Specifically, at least a portion of the base frame 110 is not equipped with a bottom module 111, thus forming a sunken space 112 in the area where the bottom module 111 is not installed. The location of the sunken space 112 corresponds to the bottom hollow area of the building module. The second inner module 122 is not supported by the bottom module 111. When the first inner mold assembly 120 is dismantled, the second inner module 122 can fall freely into the sunken space 112 located on the base frame 110 after the connection with the first inner module 121 is severed, thereby improving the dismantling efficiency of the first inner mold assembly 120.
[0088] The following is combined Figures 1 to 13 The illustrated embodiment describes the casting mold 100 of this application.
[0089] See Figures 1 to 4 In this embodiment, the concrete building module 200 includes three parts arranged along the length direction D1 (see reference). Figure 4 The middle section consists of bottomed building modules, while the left and right sides are bottomless building modules. (See reference.) Figure 3 In this embodiment, the casting mold 100 includes a base frame 110, a bottom module 111, an outer mold (not shown), and three inner molds. For the bottomless building module portion, its inner mold structure can be composed of the first inner mold assembly 120 described above. For the bottomed building module portion, its inner mold structure can be selected from the second inner mold assembly 130 described later.
[0090] In this embodiment, the first inner mold assembly 120 constituting the first inner mold includes only one first inner module 121 and one second inner module 122. The first inner module 121 is connected to the bottom module 111 and serves as the main support. The second inner module 122 is connected to the first inner module 121 and can quickly separate from the first inner module 121 during demolding (by falling into the sunken space 112). In related technologies, the base frame 110 does not have a sunken space 112. After casting, during demolding, there is friction and collision between adjacent inner modules, affecting demolding efficiency.
[0091] It is understood that in other embodiments of this application (not shown), at least two first internal modules 121 and / or two second internal modules 122 may also be provided. A first internal module 121 may be connected to two second internal modules 122 simultaneously, and a second internal module 122 may also be connected to two first internal modules 121 simultaneously.
[0092] refer to Figure 1 and Figure 2 For the side walls and bottom of the concrete building module 200, bottom modules 111 are installed on the base frame 110. For bottomless areas, no bottom modules 111 are installed, thus creating a sunken space 112. For example... Figure 1 and Figure 2 As shown, in this embodiment, the base frame 110 has two sunken spaces 112 corresponding to the two bottomless building modules. Figure 2 The shaded area corresponds to the falling area of the second inner module 122.
[0093] The first inner module 121 can be connected to the second inner module 122, for example, via a detachable connector, exemplarily a bolt and nut. (See reference...) Figure 3 and Figure 13 To facilitate the assembly of the first inner module 121 and the second inner module 122, the first inner module 121 is provided with a first connecting plate, which forms a first connecting slope 121b; the second inner module 122 is provided with a second connecting plate, which forms a second connecting slope 122b (see...). Figure 13 Bolts and nuts Figure 13 The locking component 140 connects and fixes the first connecting plate and the second connecting plate to achieve the splicing and fixing of the first inner module 121 and the second inner module 122.
[0094] See Figure 3 , Figures 5 to 8 According to one example of this application, the bottom end of the second inner module 122 extends partially into the sunken space 112 (see example 1). Figure 8 In this way, after the second inner module 122 and the first inner module 121 are disconnected, the bottom module 111 will not restrict the second inner module 122 from sliding down, and the bottom module 111 can provide guidance for the second inner module 122 to slide down, ensuring that the second inner module 122 can slide down with the bottom module 111 into the sinking space 112.
[0095] Preferably, when the first inner mold assembly 120 is assembled, the second inner module 122 is fitted against the side wall of the bottom module 111 to jointly define the side wall of the concrete building module 200. Further, a positioning element 122a is provided at the bottom end of the second inner module 122, and the positioning element 122a is detachably connected to the bottom module 111. It can be understood that the positioning element 122a is located within the sunken space 112, connecting and fixing the second inner module 122 and the bottom module 111 from the side, serving a positioning function, ensuring that the second inner module 122 is tightly fitted against the side of the bottom module 111 (the surface extending along the height direction D2), preventing it from shaking, and facilitating better support for the concrete during pouring. When disassembling the first inner mold, the positioning element 122a can be removed first, and then the second inner module 122 and the first inner module 121 can be removed.
[0096] Continue to refer to Figure 1 and Figure 2 In this embodiment, the bottom module 111 is provided with a first connecting ear plate 121a, which is configured to extend horizontally from the bottom module 111 into the recessed space 112. (See reference...) Figure 3 , Figure 6 , Figure 7 and Figure 8 In the illustrated embodiment, the bottom end of the first inner module 121 is provided with a second connecting ear plate that matches the first connecting ear plate 121a. The first connecting ear plate 121a and the second connecting ear plate are detachably connected by a locking member 140. The locking member 140 can be a bolt or nut, see reference. Figure 2 The first connecting ear plate 121a has a through hole for connecting the locking member 140. It can be understood that the first inner module 121 and the bottom module 111 can be detachably connected through the first connecting ear plate 121a, the second connecting ear plate and the locking member 140.
[0097] See Figure 2 and Figure 7A long strip-shaped second connecting ear plate is provided around the lower edge of the first inner module 121, and the first connecting ear plate 121a is correspondingly provided on the bottom module 111. It can be understood that both the first connecting ear plate 121a and the second connecting ear plate extend in the horizontal direction (parallel to the base frame 110), which can increase the contact area between the first inner module 121 and the bottom module 111, so that the first inner module 121 can be stably supported and connected to the bottom module 111, thereby enabling the first inner module 121 to better support the second inner module 122.
[0098] Continue to refer to Figure 1 In this embodiment, to better improve the support of the base frame 110 for the second inner module 122, a first support member 114 is also provided on the base frame 110. The first support member 114 is located within the sunken space 112. Specifically, the first support member 114 is constructed as a support plate laid on the base frame 110. When the second inner module 122 and the first inner module 121 are disassembled, the second inner module 122 falls and contacts the first support member 114. The first support member 114 can play a supporting and buffering role, preventing the second inner module 122 from sliding down and violently colliding with the base frame 110, thus protecting the base frame 110.
[0099] To better enhance the support of the base frame 110 for the first inner module 121, in this embodiment, the first connecting lug 121a is also connected to a second support member 115 (see...). Figure 1 The second support member 115 is located within the sunken space 112 and is connected to the base frame 110. Specifically, the second support member 115 is constructed as a support plate connected between the first connecting lug 121a and the base frame 110, serving to strengthen the support.
[0100] According to one example, the first inner module 121 includes a recessed corner, or the first inner module 121 includes two adjacent recessed corners. According to another example, the second inner module 122 includes a recessed corner, or the second inner module 122 includes two adjacent recessed corners.
[0101] like Figure 5 In the embodiment shown, the first inner mold includes two internal corner positions. The first inner module 121 and the second inner module 122 each include an internal corner. The connection position of the first inner module 121 and the second inner module 122 is set to avoid the internal corner position, which facilitates the connection and demolding of the first inner mold assembly 120, and also facilitates the concrete pouring at the internal corner position.
[0102] Among the inner modules constituting the first inner mold, at least one inner module (the second inner module 122) is not supported on the bottom module 111. When demolding the first inner mold, the weight of the second inner module 122 can be used to separate it from the first inner module 121.
[0103] The main bodies of the first inner module 121 and the second inner module 122, together with the bottom module and the outer mold, define the side walls of the concrete building module. Since the separation of the first inner module 121 and the second inner module 122 is along the height direction, see [reference needed]. Figure 6 and Figure 13 In this embodiment, the first connecting inclined surface 121b (the second connecting inclined surface 122b) is distributed approximately perpendicularly to the side wall of the concrete module formed after pouring, and the first connecting inclined surface 121b and the second connecting inclined surface 122b are inclined to the base frame 110.
[0104] The casting mold 100 also includes an outer mold, which is detachably connected to the bottom module 111. It can be understood that the outer mold is fitted outside the inner mold, and the area enclosed by the outer mold, the inner mold and the bottom module 111 is the space where concrete needs to be poured.
[0105] The concrete building module 200 of this embodiment also includes a bottomed structure in the middle section (see...). Figure 4 Therefore, the inner mold structure of this part needs to be a second inner mold component 130 that is different from the first inner mold component 120.
[0106] like Figures 9 to 12 As shown, according to an example of this application, the second inner mold assembly 130 includes a second inner mold and a connecting assembly 131. The second inner mold is connected to the outer mold via the connecting assembly 131, such that the second inner mold is suspended above the bottom module 111 (see [link]). Figure 3 , Figure 11 and Figure 12 It can be understood that the gap 135 between the second inner mold (bottom) and the bottom module 111 forms the base plate of the concrete building module 200 after the concrete is poured (see...). Figure 9 ).
[0107] Specifically, the second inner mold is composed of at least two inner modules, including a third inner module 133 and a fourth inner module 134. The third inner module 133 is fixedly connected to the outer mold via a connecting component 131. The fourth inner module 134 is detachably connected to the third inner module 133. That is, the third inner module 133 is supported and connected to the outer mold via the connecting component 131, and the load is transferred to the bottom module 111 and the base frame 110 through the outer mold. The fourth inner module 134 is connected to the third inner module 133, and when the second inner mold assembly 130 is disassembled (demolded), the fourth inner module 134 can be quickly detached from the third inner module 133.
[0108] In the inner modules constituting the second inner mold, at least one inner module (the fourth inner module 134) is not supported on the outer mold. When demolding the second inner mold, the fourth inner module 134 can be released from its locking position relative to the third inner module 133. Then, the third inner module 133 can be moved slightly towards the center of the second inner mold (for example, it can be lifted and moved slightly towards the center of the second inner mold), thus misaligning the third inner module 133 and the fourth inner module 134. This avoids frictional resistance between the third inner module 133 and the fourth inner module 134 during demolding, increasing the demolding speed of the inner mold.
[0109] Preferably, the splicing surface of the third inner module 133 and the fourth inner module 134 is constructed as an inclined surface, so that when the third inner module 133 and the fourth inner module 134 are disassembled, one of the third inner module 133 and the fourth inner module 134 can slide relative to the other along the splicing surface in the direction of the center of the second inner mold.
[0110] The third inner module 133 and the fourth inner module 134 are respectively provided with matching splicing plates 136 at the connection points (see reference). Figure 11 The splicing surfaces include a third connecting bevel and a fourth connecting bevel. The splicing plate 136 connected to the third inner module 133 forms the third connecting bevel. The splicing plate 136 connected to the fourth inner module 134 forms the fourth connecting bevel. When the fourth inner module 134 and the third inner module 133 are connected, the two splicing plates 136 are fitted together, and the fourth connecting bevel and the third connecting bevel are fitted together. The two splicing plates 136 can be locked together, for example, by bolts and nuts.
[0111] See Figure 9 and Figure 10 The main bodies of the third inner module 133 and the fourth inner module 134, together with the outer mold, define the sidewalls of the concrete module. The bottom end faces of the third inner module 133 and the fourth inner module 134, together with the bottom module 111, define the bottom plate of the concrete module. The splicing plate 136, which has a splicing surface, is approximately perpendicular to the base frame 110, and the splicing plate 136 is inclined to the outer mold (inclined to the sidewall of the concrete module at the connection position of the third inner module 133 and the fourth inner module 134 where the splicing plate 136 is located).
[0112] like Figure 10 and Figure 11 As shown, in this embodiment, the second inner mold includes two third inner modules 133 and two fourth inner modules 134. Each third inner module 133 and each fourth inner module 134 includes a concave corner. The third inner modules 133 and fourth inner modules 134 are alternately arranged in a clockwise direction, and the two third inner modules 133 and the two fourth inner modules 134 enclose a tubular structure, which is the second inner mold.
[0113] The connecting assembly 131 is disposed on the top of the third inner module 133. The connecting assembly 131 includes a support rod 131a and a connecting seat. The connecting seat includes a first connecting seat 131b fixedly connected to the third inner module 133 and a second connecting seat 131c fixedly connected to the outer mold. The ends of the support rod 131a along its length D1 are connected to the first connecting seat 131b and the second connecting seat 131c (see...). Figure 11 This allows the second inner mold to be mounted on the outer mold, and the bottom of the tubular second inner mold to be suspended above the bottom module 111.
[0114] To prevent bulging of the second inner mold, in this embodiment, the second inner mold assembly 130 further includes a third support member 132. The third support member 132 is disposed inside the box structure of the second inner mold to strengthen the support, improve the pouring effect of the concrete building module 200, and prevent deformation of the second inner mold that would make demolding difficult. See also... Figure 11 The third supporting member 132 is constructed as a diagonal bracing beam.
[0115] refer to Figures 1 to 13 The casting mold 100 in this application is particularly suitable for hybrid concrete building modules 200. After concrete pouring, the area partially enclosed by the bottom module 111, outer mold, first inner mold assembly 120, and second inner mold assembly 130 can form a concrete module building with a top opening and a bottom opening. Similarly, after concrete pouring, the area partially enclosed by the second inner mold assembly 130, bottom module 111, outer mold, and first inner mold assembly 120 can form a concrete module building with a bottom slab and a top opening. Ultimately, this allows for the simultaneous casting of both the bottom slab and the bottom-opening portion using a single casting mold 100, significantly improving the production efficiency of concrete building modules.
[0116] Regarding the aforementioned casting mold 100, this application also provides a demolding method, comprising the following steps:
[0117] For demolding the first inner mold: First, disassemble the second inner module 122 and the first inner module 121, allowing the second inner module 122 to separate from the first inner module 121 under gravity and slide downwards into the sunken space 112; then, disassemble the first inner module 121 and the bottom module 111. Finally, the first inner module 121 and the second inner module 122 can be lifted out separately using hoisting equipment. The sunken space 112 on the base frame 110 enables rapid demolding of the first inner mold.
[0118] For demolding the second inner mold: first, disassemble the fourth inner module 134 and the third inner module 133; then, disassemble the third inner module 133 and the outer mold. Then, use hoisting equipment to hoist and move the third inner module 133 or the fourth inner module 134 towards the center of the second inner mold, so that the third inner module 133 and the fourth inner module 134 are staggered.
[0119] See Figure 11 The third connecting ramp (the splicing surface formed by the splicing plates of the third inner module 133) has an inner end close to the center of the second inner mold and an outer end far from the center of the second inner mold. In this embodiment, the inner end of the third connecting ramp is closer to the fourth inner module 134 than the outer end. Therefore, the third inner module 133 is closer to the center of the second inner mold than the fourth inner module 134. During the demolding process of the second inner mold, the third inner module 133 is first hoisted and moved slightly towards the center of the second inner mold, and then the fourth inner module 134 is hoisted out from the top opening of the concrete module.
[0120] It's understandable that the fourth connecting ramp could be designed so that its inner end is closer to the third inner module than its outer end. In this case, the fourth inner module would be closer to the center of the second inner mold than the third inner module. The fourth inner module would be hoisted and transported out first.
[0121] Preferably, the casting mold 100 of this application may further include a top mold. (In conjunction with...) Figure 4 For the top of the concrete building module 200, the top formwork can be supported after the side walls and bottom positions have been poured and the inner formwork has been demolded, and then the top position of the concrete building module 200 can be poured.
