Description

Technical Field

[0001] This utility model relates to the field of template splicing technology, and in particular to a simple template splicing structure for cylindrical concrete components. Background Technology

[0002] During the construction of industrial projects, some irregular concrete components are often encountered, such as the top of a safety water tower. After the support cylinder construction is completed and the water tank is lifted, the formwork support of the circular central cylinder of the upper manhole is an irregular formwork. It cannot be constructed by slip form or inverted form. Moreover, the amount of formwork for irregular components is not large, so there is no need to customize plastic or aluminum alloy formwork.

[0003] In conventional construction methods, timber or templates cut into strips are usually spliced ​​together according to the inner and outer diameters of the cylindrical concrete component. Then, double steel bars are bent into rings and set at certain intervals around the inner and outer rings. Tie bolts or wire with large holes can be used to fix them together.

[0004] Multiple timbers or formwork panels need to be spliced ​​together according to the cylindrical concrete components. This process requires splicing them one by one, which is tedious, inefficient, and requires multiple people to operate. Utility Model Content

[0005] The purpose of this invention is to address the problem of cumbersome and inefficient template splicing steps in the prior art, and to propose a simple template splicing structure for cylindrical concrete components.

[0006] The technical solution of this utility model is: a simple template splicing structure for cylindrical concrete components, including multiple support plates, which are distributed equidistantly along a straight line, and a semi-circular groove is provided at the bottom of each support plate;

[0007] The component board includes a multi-layer plywood, bending grooves, and a smooth layer. The multi-layer plywood has bending grooves on its side. Multiple bending grooves are provided and are distributed equidistantly along the multi-layer plywood in a straight line. The multi-layer plywood is bent along the bending grooves to form a semi-cylindrical shape. The smooth layer is laid on the side of the multi-layer plywood away from the bending grooves.

[0008] The side of the multilayer plywood containing the bending groove aligns with the semi-circular groove at the bottom of the support board.

[0009] Optionally, two of the multi-layer plywoods are joined to form a cylindrical structure, the surface of the smooth layer is smooth, and concrete is poured into the smooth layer.

[0010] Optionally, the sides of the plywood are cut every 50mm to 80mm to form bending grooves, and the cutting depth of the bending grooves is one-third to one-half of the thickness of the plywood.

[0011] Optionally, the bottom of the support plate is provided with a support assembly, which includes a strip plate, a sliding groove and an insert rod. The top of the strip plate has a sliding groove, and the insert rod is slidably connected inside the sliding groove. The insert rod is inserted into the interior of the support plate.

[0012] Optionally, a slider is fixedly installed at the bottom of the insertion rod, the insertion rod and the slider form a convex structure, the cross-section of the sliding groove adopts a convex structure, and both the insertion rod and the slider slide within the sliding groove.

[0013] Optionally, a slot is provided at the bottom of the support plate, and the slot at the bottom of the support plate slides on the top of the strip plate.

[0014] Optionally, a round hole is provided at the corner of the support plate, and the same connecting column is inserted into the round hole of multiple support plates.

[0015] Optionally, a sheet metal is fixedly installed in the semi-circular groove of the support plate, and the sheet metal is attached to the outer arc surface of the multi-layer plywood.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects:

[0017] This invention involves cutting multiple curved grooves on the side of a multi-layer plywood, bending the plywood along the curved grooves to form an arc plate, splicing two multi-layer plywoods to form a cylinder, and pouring concrete into the smooth surface layer. The curved grooves can be cut in advance, and the multi-layer plywood can be cut to the required length. The process is simple, efficient, and has no gaps, ensuring that the cast concrete component has a smooth and flat appearance.

[0018] Furthermore, by using strip plates and insert rods to support the support plates, the problem of the support plates tilting and failing to provide support for the plywood is prevented. In addition, connecting columns link multiple support plates together, ensuring they are parallel to each other and improving the stability of the support plates for the plywood. Moreover, more support plates can be added to support the plywood as needed, depending on its length. Attached Figure Description

[0029] Example 1

[0030] This embodiment proposes a simple formwork splicing structure for cylindrical concrete components, such as... Figure 1 As shown, it includes multiple support plates 1, which are equidistantly distributed along a straight line, and a semi-circular groove is provided at the bottom of the support plate 1.

[0031] like Figure 2 and Figure 3 As shown, a component plate 3 is provided at the bottom semi-circular groove of the support plate 1. The component plate 3 includes a multi-layer plywood 31, a bending groove 32, and a smooth layer 33. The side of the multi-layer plywood 31 is provided with a bending groove 32. Multiple bending grooves 32 are provided and are distributed in a straight line at equal intervals along the multi-layer plywood 31. The multi-layer plywood 31 is bent along the bending groove 32 to form a semi-cylindrical shape. Two multi-layer plywood 31 are combined to form a cylindrical structure.

[0032] The plywood 31 is bent through bending grooves 32, thereby forming a semi-cylindrical structure. Bending grooves 32 are cut every 50mm to 80mm along the side of the plywood 31, with a cutting depth of one-third to one-half the thickness of the plywood 31. This prevents the plywood 31 from breaking during bending due to excessive cutting depth. Instead of cutting into strips and then constraining, the bending grooves 32 can be pre-cut, and the plywood 31 can be cut to the required length.

[0033] A sheet metal 2 is fixedly installed in the semi-circular groove of the support plate 1, and the sheet metal 2 is attached to the outer arc surface of the plywood 31. The sheet metal 2 increases the contact area, making the plywood 31 bear force evenly.

[0034] like Figure 2 As shown, a smooth layer 33 is laid on the side of the multi-layer plywood 31 away from the bending groove 32. The surface of the smooth layer 33 is smooth, and concrete is poured into the smooth layer 33.

[0035] The circumference is calculated as πd based on the outer diameter of the well wall. The required multi-layer plywood of specification 31 is cut according to the outer diameter circumference of the circular component. Since the outer diameter of the well wall is not large, the outer mold can be made into two parts and assembled together to facilitate the support, fixation and dismantling of the template.

[0036] Use a hand saw to cut the support plate into two semi-circular rings. The inner dimensions of the rings must be accurate. Based on the length of the plywood 31, mark out ink lines every 50mm to 80mm on the plywood 31, adjusting according to the diameter of the circular component. Then, use the hand saw to cut along each line. Do not cut through the plywood 31. The cutting depth should be 1 / 2 to 2 / 3 of the template thickness. Ensure that the other side of the plywood 31 is connected so that the plywood 31 can be bent and fixed.

[0037] The cut plywood 31 is attached and fixed along the semi-circular groove at the bottom of the support plate 1 to form a semi-circular template. The outer mold of the circular component is erected by placing the prepared semi-circular template on the outside of the already tied reinforcing bars and securing it with wire or thin steel bars every 500mm. Following the above steps, the plywood 31 is bent in the reverse direction to obtain the inner mold. The outer mold and inner mold are then fitted together to form a cylindrical component.

[0038] In this embodiment, multiple bending grooves 32 are formed by cutting the side of the multi-layer plywood 31. The multi-layer plywood 31 is bent along the bending grooves 32 to form an arc plate. Two multi-layer plywood 31 are spliced ​​together to form a cylinder. Concrete is poured into the smooth layer 33. There is no need to cut it into strips and then constrain it. The bending grooves 32 can be cut in advance, and the multi-layer plywood 31 can be cut according to the required length. The steps are simple and efficient.

[0039] Example 2

[0040] Based on Example 1, this example proposes a simple formwork splicing structure for cylindrical concrete components, such as... Figure 1 and Figure 4 As shown, a support assembly 4 is provided at the bottom of the support plate 1. The support assembly 4 includes a strip plate 41, a sliding groove 42, and a rod 43. The sliding groove 42 is formed at the top of the strip plate 41, and the rod 43 is slidably connected inside the sliding groove 42. The rod 43 is inserted into the interior of the support plate 1. The support plate 1 is supported by the strip plate 41 and the rod 43, preventing the support plate 1 from tilting and failing to provide support for the multilayer plywood 31.

[0041] A slot 45 is provided at the bottom of the support plate 1, and the slot 45 at the bottom of the support plate 1 slides on the top of the strip plate 41.

[0042] A slider 44 is fixedly installed at the bottom of the insert rod 43, forming a convex structure with the insert rod 43 and the slider 44. The cross-section of the sliding groove 42 also has a convex structure, and both the insert rod 43 and the slider 44 slide within the sliding groove 42. By sliding the insert rod 43 and the slider 44, the position of the support plate 1 supporting the plywood 31 can be changed. When the plywood 31 is too long, insert rods 43 and sliders 44 can be added from the sliding groove 42 to increase the number of support plates 1 supporting the plywood 31.

[0043] A round hole is provided at the corner of the support plate 1, and the same connecting post 46 is inserted into the round hole of multiple support plates 1. The multiple support plates 1 are connected by the connecting post 46, so that the multiple support plates 1 are parallel to each other, thereby improving the support stability of the support plates 1 on the multilayer plywood 31.

[0044] In this embodiment, the support plate 1 is supported by the strip plate 41 and the insert rod 43 to prevent the support plate 1 from tilting and failing to provide support for the multilayer plywood 31. Furthermore, the connecting column 46 connects multiple support plates 1, making them parallel to each other and improving the stability of the support plate 1 in supporting the multilayer plywood 31. Additionally, more support plates 1 can be added to support the multilayer plywood 31 according to its length.

[0045] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
