Description

Technical Field

[0001] The utility model relates to the technical field of caisson templates, in particular to an inner template with chamfers. Background Art

[0002] Caissons are a common underwater construction technology for buildings and bridge foundations, widely used in projects such as ports, bridges, and underwater tunnels. Caissons are typically prefabricated onshore, sunk into a designated location in the water, and then filled with concrete or other materials to serve as part of the foundation structure.

[0003] During the actual casting process, multiple inner formworks are installed at intervals inside the outer formwork of the caisson. The inner formwork of the caisson consists of a horizontal section and a vertical section. During use, the two horizontal sections and two vertical sections are assembled and formed. The cavity of the caisson is often provided with chamfers, so insert plates are often installed at the connection between the horizontal and vertical sections. However, during the casting process of the caisson, the lateral pressure on the insert plates increases with the height of the caisson casting. Therefore, there is a risk that the insert plates will be displaced due to excessive lateral pressure, affecting the casting quality of the caisson. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art in that the inner formwork of the caisson is provided with insert plates at the chamfers, but there is a risk of displacement of the insert plates when casting the caisson, which affects the casting quality of the caisson, and to provide an inner formwork with chamfers.

[0005] In a first aspect, the present invention provides an inner formwork with chamfers, comprising a transverse section, a vertical section, and an inner frame, wherein the inner frame is used to support the transverse section and the vertical section, wherein the transverse section and the vertical section are connected by a chamfered section, wherein the chamfered section comprises:

[0006] a first chamfered panel, the first chamfered panel being arranged at an end of the transverse section, the first chamfered panel and the transverse section forming an angle, and a first connecting surface being arranged on a side of the first chamfered panel away from the transverse section;

[0007] A second chamfered panel is provided at the end of the vertical segment, the second chamfered panel comprises a chamfered surface and a second connecting surface, the angle between the chamfered surface and the vertical segment matches the angle between the first chamfered panel and the transverse segment, the second connecting surface faces away from the vertical segment, and the second connecting surface is used to connect to the first connecting surface.

[0008] The first chamfered panel can also be connected to the vertical section, and the second chamfered panel can also be connected to the horizontal section.

[0009] When the inner formwork is in operation, the first inner formwork and the second inner formwork are connected and assembled via the first connecting surface and the second connecting surface; the angle between the first chamfered panel and the horizontal segment matches the angle between the chamfered surface and the vertical segment, so when the first connecting surface and the second connecting surface are connected, the outer side surface of the first chamfered panel and the chamfered surface can be connected to form a smooth outer surface. Compared to the prior art caisson inner formwork that has insert plates set at the chamfers, the chamfered sections of this device are directly set on the horizontal and vertical sections of the inner formwork. During pouring, the position of the chamfered sections can be fixed by fixing the positions of the horizontal and vertical sections of the inner formwork, and the chamfered sections are not easily deformed, which can minimize displacement that affects the pouring quality of the caisson.

[0010] Preferably, a sealing member is further included, and the sealing member is used to be arranged between the first connecting surface and the second connecting surface.

[0011] The seal can be fixed to the first connecting surface or the second connecting surface, or can be fixed by squeezing the first and second connecting surfaces. The provision of the seal enhances the sealing performance of the inner formwork. During use, when liquid is stored within the caisson, leakage of the liquid through the inner formwork and erosion of the caisson structure are minimized.

[0012] Preferably, the sealing member is a rubber member, a polyurethane member or a silicone member.

[0013] The rubber component, the polyurethane component and the silicone component are all flexible and waterproof sealing components, which are beneficial to improving the sealing performance of the inner template.

[0014] Preferably, the sealing member is fixed to the first connecting surface by bolts.

[0015] The seal is fixed to the first connection surface by bolts to avoid displacement of the seal as much as possible, which may affect the sealing performance of the inner template.

[0016] Preferably, the inner surfaces of the transverse section and the vertical section are both connected with trusses, and the inner frame is connected to the transverse section and the vertical section through the trusses.

[0017] Trusses are arranged on the inner surfaces of the transverse and vertical sections, which is beneficial to enhancing the bearing capacity of the transverse and vertical sections, and can also avoid deformation or displacement of the transverse and vertical sections as much as possible, thereby avoiding affecting the casting quality of the caisson during casting.

[0018] Preferably, it further comprises a pushing member, which is used to push the transverse section and the vertical section to a predetermined position, and the pushing member is connected to the transverse section and the vertical section through the truss.

[0019] If a pushing member is connected to the truss, the pushing force is transmitted to the horizontal section or the vertical section through the truss during the pushing operation, which can avoid stress concentration in the horizontal section and the vertical section as much as possible.

[0020] Preferably, the pushing member comprises a screw, one end of which is used to connect to the truss, and the other end of which is connected to the inner frame via a nut.

[0021] The lead screw can be rotated to move in a direction away from the inner frame, thereby pushing the inner frame.

[0022] Preferably, the first connecting surface and the axis of the first chamfered panel form an included angle, and the included angle between the second connecting surface and the axis of the second chamfered panel matches the included angle between the first connecting surface and the axis of the first chamfered panel.

[0023] If the first connecting surface and the axis of the first chamfered panel form an angle, the area of ​​the first connecting surface will be correspondingly increased. If the angle between the second connecting surface and the axis of the second chamfered panel matches the angle between the first connecting surface and the axis of the first chamfered panel, then when the vertical section and the horizontal section are installed in place, the plane of the first connecting surface is parallel to the plane of the second connecting surface, maximizing the contact area between the first and second connecting surfaces and enhancing the sealing of the inner formwork.

[0024] Preferably, the distance from the inner side of the first connecting surface to the transverse section is greater than the distance from the outer side of the first connecting surface to the transverse section.

[0025] The inner side of the first connecting surface is the side close to the other end of the transverse section; the outer side of the first connecting surface is the side away from the other end of the transverse section. In actual use, the installation space of the inner formwork of the caisson is limited. Therefore, during installation, it is necessary to push the transverse section and the vertical section from the inside of the inner formwork to the predetermined position. Because there is an angle between the first chamfered panel and the transverse section, it is more efficient to install the transverse section first during the installation of the inner formwork. The inner side of the first connecting surface is inclined toward the transverse section, so when the transverse section is installed in place, the first chamfered panel will not affect the pushing movement of the vertical section; and when the vertical section is pushed, if it is pushed into place, the protruding first connecting surface will limit the vertical section from continuing to push, which is beneficial to the positioning of the vertical section.

[0026] Preferably, an oblique rod is further provided inside the inner frame.

[0027] Diagonal rods are also provided inside the inner frame to improve the bearing capacity of the inner frame and avoid displacement of the inner formwork as much as possible.

[0028] Compared with the existing technology, the beneficial effects of the present invention are:

[0029] 1. The utility model provides an inner template with chamfers, comprising a first chamfered panel and a second chamfered panel, the first chamfered panel and the second chamfered panel being respectively arranged at the ends of the transverse section and the vertical section, the first chamfered panel and the transverse section having an angle, and the first chamfered panel being provided with a first connecting surface; the second chamfered panel comprising a chamfered surface and a second connecting surface, the second connecting surface being used to connect to the first connecting surface, the angle between the chamfered surface and the vertical section matching the angle between the first chamfered panel and the transverse section. When the inner template is in working state, the first inner template and the second inner template are connected by the first connecting surface and the second connecting surface.

[0030] The second connecting surface is connected and assembled; the angle between the first chamfered panel and the horizontal line segment matches the angle between the chamfered surface and the vertical segment. Then, when the first connecting surface is connected to the second connecting surface, the outer side surface of the first chamfered panel and the chamfered surface can be connected to form a smooth outer surface. Compared with the prior art caisson inner formwork that sets a plug-in plate at the chamfer, the chamfered section of the present device is directly set on the transverse section and vertical section of the inner formwork. Then, during pouring, the position of the chamfered section can be fixed by fixing the position of the transverse section and vertical section of the inner formwork, avoiding displacement as much as possible to affect the pouring quality of the caisson. The present device overcomes the shortcomings of the prior art that the inner formwork of the caisson is provided with a plug-in plate at the chamfer, but when pouring the caisson, there is a risk of displacement of the plug-in plate, which affects the pouring quality of the caisson.

[0040] Example 1

[0041] like Figure 1 and Figure 2 As shown, an inner formwork with chamfers comprises a transverse section 1, a vertical section 2 and an inner frame 5, wherein the inner frame 5 is used to support the transverse section 1 and the vertical section 2, and the transverse section 1 and the vertical section 2 are connected by a chamfer section, wherein the chamfer section comprises:

[0042] a first chamfered panel 11, which is disposed at an end of the transverse section 1, wherein an angle is formed between the first chamfered panel 11 and the transverse section 1, and a first connecting surface 111 is disposed on a side of the first chamfered panel 11 away from the transverse section 1;

[0043] The second chamfered panel 21 is arranged at the end of the vertical section 2. The second chamfered panel 21 includes a chamfered surface 211 and a second connecting surface 212. The angle between the chamfered surface 211 and the vertical section 2 matches the angle between the first chamfered panel 11 and the transverse section 1. The second connecting surface 212 faces away from the vertical section 2. The second connecting surface 212 is used to connect to the first connecting surface 111.

[0044] When the inner formwork is in operation, the first inner formwork and the second inner formwork are connected and assembled via the first connecting surface 111 and the second connecting surface 212; the angle between the first chamfered panel 11 and the horizontal segment matches the angle between the chamfered surface 211 and the vertical segment 2. Therefore, when the first connecting surface 111 and the second connecting surface 212 are connected, the outer side surface of the first chamfered panel 11 and the chamfered surface 211 can be connected to form a smooth outer surface. Compared to the prior art caisson inner formwork that has insert plates set at the chamfers, the chamfered sections of this device are directly set on the transverse section 1 and vertical section 2 of the inner formwork. Therefore, during pouring, the position of the chamfered sections can be fixed by fixing the positions of the transverse section 1 and vertical section 2 of the inner formwork, thereby minimizing displacement that affects the pouring quality of the caisson.

[0045] Furthermore, it also includes a seal 3, which is used to be arranged between the first connecting surface 111 and the second connecting surface 212. The provision of the seal 3 is conducive to strengthening the sealing performance of the inner template. When the liquid is stored inside the caisson during use, it is necessary to avoid the liquid from seeping out of the inner template and causing erosion to the caisson structure as much as possible. In this embodiment, the area of ​​the first connecting surface 111 is larger than that of the second connecting surface 212, so the seal 3 is fixed to the first connecting surface 111 to ensure the stability of the structure. In other embodiments, it can also be connected to the second connecting surface 212 according to actual conditions. In this embodiment, the seal 3 is a rubber component, which is fixed to the first connecting surface 111 by bolts 31. Rubber is a flexible waterproof component, which is conducive to ensuring the sealing performance of the device and avoiding liquid erosion of the caisson as much as possible.

[0046] Furthermore, the inner surfaces of the transverse section 1 and the vertical section 2 are connected with trusses 4, and the inner frame 5 is connected to the transverse section 1 and the vertical section 2 via the trusses 4. The arrangement of the trusses 4 on the inner surfaces of the transverse section 1 and the vertical section 2 is beneficial for enhancing the bearing capacity of the transverse section 1 and the vertical section 2, and can also avoid deformation or displacement of the transverse section 1 and the vertical section 2 as much as possible, thereby avoiding affecting the casting quality of the caisson during casting. The rubber components can also be replaced with polyurethane components or silicone components.

[0047] It also includes a pushing member, which is used to push the transverse section 1 and the vertical section 2 to a predetermined position. The pushing member is connected to the transverse section 1 and the vertical section 2 through the truss 4. If the pushing member is connected to the truss 4, the pushing force is transmitted to the transverse section 1 or the vertical section 2 through the truss 4 during the pushing operation, which can avoid stress concentration in the transverse section 1 and the vertical section 2 as much as possible. In this embodiment, the pushing member includes a screw 51, one end of which is used to connect to the truss 4, and the other end is connected to the inner frame 5 through a nut. The screw 51 can be rotated to move in a direction away from the inner frame 5, thereby pushing the inner frame 5.

[0048] The first connecting surface 111 and the axis of the first chamfered panel 11 form an angle, and the angle between the second connecting surface 212 and the axis of the second chamfered panel 21 matches the angle between the first connecting surface 111 and the axis of the first chamfered panel 11. If the first connecting surface 111 and the axis of the first chamfered panel 11 form an angle, the area of ​​the first connecting surface 111 will be correspondingly larger. If the angle between the axis of the second connecting surface 212 and the axis of the second chamfered panel 21 matches the angle between the axis of the first connecting surface 111 and the axis of the first chamfered panel 11, then when the vertical section 2 and the horizontal section 1 are installed in place, the plane where the first connecting surface 111 is located is parallel to the plane where the second connecting surface 212 is located, thereby maximizing the contact area between the first connecting surface 111 and the second connecting surface 212, which is conducive to enhancing the sealing of the inner template.

[0049] In this embodiment, the distance from the inner side of the first connecting surface 111 to the transverse section 1 is greater than the distance from the outer side of the first connecting surface 111 to the transverse section 1. The inner side of the first connecting surface 111 is the side close to the other end of the transverse section 1; the outer side of the first connecting surface 111 is the side away from the other end of the transverse section 1. In actual use, the installation space of the inner formwork of the caisson is limited. Therefore, during installation, it is necessary to push the transverse section 1 and the vertical section 2 from the inside of the inner formwork to the predetermined position. Because the first chamfered panel 11 and the transverse section 1 are at an angle, it is more efficient to install the transverse section 1 first during the installation of the inner formwork. The inner side of the first connecting surface 111 is inclined toward the transverse section 1. Therefore, when the transverse section 1 is installed in place, the first chamfered panel 11 will not affect the pushing movement of the vertical section 2. Moreover, when the vertical section 2 is pushed in place, if the pushing is in place, the protruding first connecting surface 111 will limit the vertical section 2 from continuing to push, which is beneficial to the positioning of the vertical section 2.

[0050] The inner frame 5 is further provided with an oblique rod 52. The inner frame 5 is further provided with an oblique rod 52 to improve the bearing capacity of the inner frame 5 and to avoid displacement of the inner template as much as possible.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
