Description

Technical Field

[0001] The present invention belongs to the technical field of prefabricated concrete preparation, in particular to a supporting structure for prefabricated concrete. Background Art

[0002] Currently, when preparing prefabricated concrete wall panels, concrete needs to be poured into a predetermined mold, and the concrete is solidified and formed in the mold to form a wall panel structure.

[0003] In the prior art, when removing the formwork of concrete wall panels, external force is mostly applied to the formwork to separate the formwork from the concrete wall panels. On the one hand, this method is likely to cause deformation and damage to the formwork, resulting in a short service life of the formwork. On the other hand, it is also likely to cause the concrete wall panels to crack, thereby affecting the qualification rate of the concrete wall panels. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a prefabricated concrete support structure.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] An assembled concrete support structure includes a bracket, a mold, a flexible cutting assembly, a second drive assembly, and a third drive assembly.

[0007] The mold is arranged on one side of the bracket and is used to support and enclose the concrete.

[0008] The flexible cutting assembly is attached to the inner wall of the mold to form a U-shaped structure that matches the inner cavity of the mold.

[0009] The second driving assembly is mounted on one side of the bracket and is used to drive the flexible cutting assembly to move in contact with the inner wall of the mold.

[0010] The third driving assembly is installed on the outside of the mold and is used to drive the flexible cutting assembly to move back and forth along a U-shaped track.

[0011] As a further improvement of the present invention: the second drive assembly is symmetrically distributed on the outside of the mold and is provided with two groups. The two groups of the second drive assembly have the same structure and both include a first motor, a screw rod and a sleeve.

[0012] The first motors corresponding to the two sets of the second drive assemblies are fixedly mounted on one side of the bracket, and one end of the screw rods corresponding to the two sets of the second drive assemblies is respectively connected to the output end of one set of the first motors, and each set of the screw rods is sleeved with two sets of the sleeves.

[0013] The flexible cutting components are provided in two groups, wherein the two ends of one group of flexible cutting components are respectively connected to the two groups of sleeves on the two groups of screw rods, and the two ends of the other group of flexible cutting components are respectively connected to the other two groups of sleeves on the two groups of screw rods.

[0014] As a further improvement of the present invention: a support plate is fixedly provided on one side of each of the four groups of sleeves, and the four groups of support plates extend to the outside of the mold and slide with the mold respectively.

[0015] There are four groups of the third drive components, and the four groups of the third drive components are respectively installed on the side of the four groups of support plates away from the mold.

[0016] Two ends of one group of the flexible cutting components pass through the corresponding two groups of sleeves and are connected to two groups of the third drive components.

[0017] The two ends of the flexible cutting assembly on the other side pass around the corresponding two groups of sleeves and are connected to the other two groups of third drive assemblies.

[0018] As a further improvement of the present invention: a limiting ring is fixedly provided on one side of the sleeve for the flexible cutting assembly to pass through.

[0019] The third driving assembly includes a second motor and a reel.

[0020] A mounting plate is fixedly provided on one side of the support plate, the second motor is fixedly installed on one side of the mounting plate, the reel is provided at the output end of the second motor, and the flexible cutting assembly passes through the limiting ring and is wound around the outside of the reel.

[0021] As a further improvement of the present invention: the mold includes a frame side template and a bottom template attached to one side of the frame side template,

[0022] A guide rail is fixedly provided on the outer wall of the frame side template, the frame side template is fixedly installed on one side of the bracket, and a card slot adapted to the guide rail is opened on one side of the support plate.

[0023] As a further improvement of the present invention: a first driving assembly is provided on one side of the bracket, and the first driving assembly is used to drive the bottom template to move away from the frame side template.

[0024] As a further improvement of the present invention: a groove for accommodating the flexible cutting assembly is provided in the middle of one side of the bottom template and in the middle of the inner wall of the frame side template.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] In an embodiment of the present invention, concrete is poured into the inner side of the mold and the mold is used to define the concrete into a rectangular wall panel. After the concrete is solidified and formed, the second driving component drives the flexible cutting component to move in contact with the inside of the mold, thereby horizontally cutting the bonding portion between the concrete and the inner wall of the mold, so that the concrete is quickly separated from the mold, so as to facilitate the subsequent detachment of the concrete wall panel from the mold, thereby achieving rapid demolding of the concrete wall panel. While the second driving component drives the flexible cutting component to move in contact with the inner wall of the mold, the third driving component drives the flexible cutting component to move back and forth along a U-shaped trajectory, thereby longitudinally cutting the bonding portion between the concrete and the inner wall of the mold, thereby improving the separation effect of the concrete wall panel from the inner wall of the mold. Compared with the existing technology, the rapid demolding of the concrete wall panel can be achieved without applying external force to dismantle the template, thereby avoiding deformation and damage of the template due to force, and at the same time avoiding cracking of the concrete wall panel during the template disassembly process, which has the advantages of quick and convenient demolding.

DETAILED DESCRIPTION

[0032] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0033] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] See also Figure 1 and Figure 2 This embodiment provides a support structure for prefabricated concrete, including a bracket 10, a mold 30, a flexible cutting assembly 40, a second drive assembly 50 and a third drive assembly 60. The mold 30 is arranged on one side of the bracket 10 for supporting and enclosing concrete. The flexible cutting assembly 40 is attached to the inner wall of the mold 30 to form a U-shaped structure that matches the inner cavity of the mold 30. The second drive assembly 50 is installed on one side of the bracket 10 for driving the flexible cutting assembly 40 to move in contact with the inner wall of the mold 30. The third drive assembly 60 is installed on the outside of the mold 30 for driving the flexible cutting assembly 40 to move back and forth along the U-shaped track.

[0035] By pouring concrete into the inner side of the mold 30, the mold 30 is used to define the concrete into a rectangular wall panel. After the concrete is solidified and formed, the second drive component 50 drives the flexible cutting component 40 to move in contact with the inside of the mold 30, and then the bonding part between the concrete and the inner wall of the mold 30 is cut horizontally, so that the concrete is quickly separated from the mold 30, so that the concrete wall panel can be subsequently separated from the mold 30, thereby achieving rapid demolding of the concrete wall panel. While the second drive component 50 drives the flexible cutting component 40 to move in contact with the inner wall of the mold 30, the third drive component 60 drives the flexible cutting component 40 to move back and forth along a U-shaped trajectory, and then the bonding part between the concrete and the inner wall of the mold 30 can be cut longitudinally, so as to improve the separation effect of the concrete wall panel and the inner wall of the mold 30.

[0036] See also Figure 1 and Figure 4 In one embodiment, two groups of the second drive components 50 are symmetrically distributed on the outside of the mold 30. The two groups of the second drive components 50 have the same structure and both include a first motor 501, a screw rod 502 and a sleeve 503. The first motors 501 corresponding to the two groups of the second drive components 50 are fixedly installed on one side of the bracket 10, and one end of the screw rods 502 corresponding to the two groups of the second drive components 50 are respectively connected to the output end of one group of the first motors 501, and each group of the screw rods 502 is sleeved with two groups of the sleeves 503. The flexible cutting components 40 are provided with two groups, and the two ends of one group of the flexible cutting components 40 are respectively connected to the two groups of the sleeves 503 on the two groups of the screw rods 502, and the two ends of the other group of the flexible cutting components 40 are respectively connected to the other two groups of the sleeves 503 on the two groups of the screw rods 502.

[0037] Initially, the two groups of flexible cutting components 40 are located in the middle position inside the mold 30. When the concrete is solidified and formed into a wall panel, the two groups of first motors 501 respectively drive the two groups of screw rods 502 to rotate, and the cooperation between the screw rods 502 and the sleeves 503 is utilized to drive the two groups of sleeves 503 located on the same group of screw rods 502 away from each other, thereby driving the two groups of flexible cutting components 40 to fit the inner wall of the mold 30 and move away from each other, and move from the middle position to the edge of the mold 30 to achieve transverse cutting of the bonding part between the concrete wall panel and the mold 30, so that the concrete wall panel is separated from the mold 30, so that the concrete wall panel can be quickly demolded from the mold 30.

[0038] See also Figure 2 and Figure 4 In one embodiment, a support plate 505 is fixedly provided on one side of the four groups of sleeves 503, and the four groups of support plates 505 respectively extend to the outside of the mold 30 and slide with the mold 30. The third drive assembly 60 is provided with four groups, and the four groups of third drive assemblies 60 are respectively installed on the side of the four groups of support plates 505 away from the mold 30, and the two ends of one group of flexible cutting assemblies 40 bypass the corresponding two groups of sleeves 503 and are connected to two groups of the third drive assemblies 60, and the two ends of the flexible cutting assembly 40 on the other side bypass the corresponding two groups of sleeves 503 and are connected to the other two groups of the third drive assemblies 60.

[0039] When the two sets of sleeves 503 on the screw rod 502 move away from each other, the corresponding flexible cutting assembly 40 is driven by the third driving assembly 60 to move in a U-shaped trajectory inside the mold 30 to longitudinally cut the bonding part between the concrete wall panel and the mold 30, which can reduce the resistance of the cutting assembly 40 during lateral movement, thereby improving the separation effect between the concrete wall panel and the mold 30.

[0040] See also Figure 2 and Figure 4 In one embodiment, a limiting ring 504 is fixedly provided on one side of the sleeve 503 for the flexible cutting component 40 to pass through, the third driving component 60 includes a second motor 601 and a reel 602, and a mounting plate 506 is fixedly provided on one side of the support plate 505. The second motor 601 is fixedly mounted on one side of the mounting plate 506, and the reel 602 is arranged at the output end of the second motor 601. The flexible cutting component 40 passes through the limiting ring 504 and is wound around the outside of the reel 602.

[0041] When the flexible cutting assembly 40 is moved in contact with the inner wall of the mold 30, one of the second motors 601 drives the corresponding reel 602 to rotate forward to reel in one end of the flexible cutting assembly 40, and the other second motor 601 drives the corresponding reel 602 to rotate backward to unreel the other end of the flexible cutting assembly 40, so that the flexible cutting assembly 40 moves along a U-shaped trajectory inside the mold 30 to longitudinally cut the bonded portion between the concrete wall panel and the mold 30; when the flexible cutting assembly 40 moves from the middle position of the mold 30 to the edge position, the second motor 601 that originally drives the flexible cutting assembly 40 to unreel stops running, and the second motor 601 that originally drives the flexible cutting assembly 40 to reel continues to rotate. At this time, the flexible cutting assembly 40 can be gradually straightened from the U-shaped structure. During this process, the flexible cutting assembly 40 can be moved out of the mold 30 from one side wall inside the mold 30. In this way, the flexible cutting assembly 40 can cut all five contact surfaces between the concrete wall panel and the inner wall of the mold 30, so that the concrete wall panel and the inner wall of the mold 30 are completely separated.

[0042] See also Figure 2 In one embodiment, the mold 30 includes a frame side template 302 and a bottom template 301 attached to one side of the frame side template 302. The outer wall of the frame side template 302 is fixedly provided with a guide rail 304. The frame side template 302 is fixedly installed on one side of the bracket 10. A card slot adapted to the guide rail 304 is opened on one side of the support plate 505. When the screw rod 502 rotates, the support plate 505 slides with the guide rail 303 through the card slot, thereby ensuring that the sleeve 503 can move in coordination with the screw rod 502; a first driving component 20 is provided on one side of the bracket 10, and the first driving component 20 is used to drive the bottom template 301 to move away from the frame side template 302.

[0043] When the flexible cutting component 40 moves from the middle position inside the frame side formwork 302 to the edge position, and then moves out from the edge position to the outside of the frame side formwork 302, the first driving component 20 drives the bottom formwork 301 away from the frame side formwork 302. At this time, the concrete wall panel can be moved out from the inside of the frame side formwork 302 as the bottom formwork 301 moves. Then the staff can use the lifting machinery to transfer the concrete wall panel on the bottom formwork 301.

[0044] In one embodiment, the first driving component 20 can be a hydraulic lifting rod or a linear motor, which is not limited here. The flexible cutting component 40 can be a steel wire rope or other high-strength metal wire, which is not limited here.

[0045] See also Figure 3In one embodiment, a groove 303 for accommodating the flexible cutting component 40 is provided in the middle position of one side of the bottom template 301 and in the middle position of the inner wall of the frame side template 302. Through the setting of the groove 303, the flexible cutting component 40 can be buried inside the groove 303 during the concrete pouring process, thereby avoiding the flexible cutting component 40 from being exposed in the pouring area inside the mold 30, resulting in a depression in the shape of the flexible cutting component 40 on the surface of the concrete wall panel after it is formed.

[0046] In an embodiment of the present invention, concrete is poured into the inner side of the mold 30, and the mold 30 is used to define the concrete into a rectangular wall panel. After the concrete is solidified and formed, the second drive component 50 drives the flexible cutting component 40 to move in contact with the inside of the mold 30, thereby horizontally cutting the bonded portion between the concrete and the inner wall of the mold 30, so that the concrete is quickly separated from the mold 30, so as to facilitate the subsequent separation of the concrete wall panel from the mold 30, thereby achieving rapid demolding of the concrete wall panel. While the second drive component 50 drives the flexible cutting component 40 to move in contact with the inner wall of the mold 30, the third drive component 60 drives the flexible cutting component 40 to move back and forth along a U-shaped trajectory, thereby longitudinally cutting the bonded portion between the concrete and the inner wall of the mold 30, thereby improving the separation effect of the concrete wall panel from the inner wall of the mold 30. Compared with the prior art, the concrete wall panel can be quickly demolded without applying external force to dismantle the template, thereby avoiding deformation and damage of the template due to force, and at the same time avoiding cracking of the concrete wall panel during the template removal process, which has the advantages of quick and convenient demolding.
