[0025] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.
[0026] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0027] Please refer to Figure 1 The present application provides a plain concrete formwork with a supporting structure, comprising a spacer bar 1, wherein formwork units are respectively installed at both ends of the spacer bar 1, and a pouring space 3 is formed between the two formwork units;
[0028] The template unit comprises:
[0029] A formwork body 2, which is arranged perpendicular to the spacer rod 1 and connected to the end of the spacer rod 1, and is made of concrete; a side of the formwork body 2 away from the pouring space 3 forms a pressure surface;
[0030] A support assembly is provided on a side of the formwork body 2 away from the pouring space 3 and is detachably connected to the formwork body 2; the support assembly includes a plurality of support portions 4, and the plurality of support portions 4 at least support the corner positions of the pressure surface.
[0031] Specifically, the plain concrete formwork provided in the present application includes two formwork units, the two formwork units are used for pouring plain concrete, the two formwork units are separated by a spacer rod 1, and the two ends of the spacer rod 1 are detachably connected to the two formwork units. The formwork unit is composed of a formwork body 2 and a support assembly. The formwork body 2 is a rectangular plate-shaped structure made of concrete. The formwork body 2 made of concrete is the same material as the plain concrete to be poured. The two have the same expansion coefficient, similar surface roughness and consistent water absorption. When the temperature changes, the formwork body 2 and the poured plain concrete can expand or contract synchronously, avoiding surface cracking. The similar surface roughness helps to reduce adhesion and surface damage during demoulding, keeping the concrete surface smooth and flat. In addition, the consistent water absorption can avoid the problems of surface unevenness and roughness caused by uneven water absorption.
[0032] The template body 2 is provided with mounting holes at the center and four corners respectively. The end of the spacer rod 1 is connected to the mounting hole at the center of the template body 2 and can be fixed by bolts. The template body 2 is arranged perpendicular to the spacer rod 1. The side of the template body 2 facing the spacer rod 1 serves as the side wall of the casting space 3, and the side of the template body 2 facing away from the spacer rod 1 forms the pressure surface. The support assembly is installed on the side of the formwork body 2 close to the pressure surface. The support assembly is used to maintain the stability of the formwork body 2 during the pouring process. During the pouring process, the support assembly supports the formwork body 2 on the side of the pressure surface of the formwork body 2; the support assembly includes a plurality of support parts 4. In this embodiment, the number of the support parts 4 is four, and the four support parts 4 correspond to the mounting holes at the four corners of the formwork body 2. The support parts 4 are connected to the mounting holes by bolts, thereby realizing a detachable connection between the support parts 4 and the formwork body 2; when the support parts 4 are connected to the formwork body 2, the support parts 4 support the corners of the formwork body 2 to avoid the problem of the formwork body 2 being broken due to uneven force during the pouring process.
[0033] By setting the support assembly, the support assembly can maintain the stability of the shape and position of the formwork body 2, prevent the concrete from being deformed or displaced during the pouring and vibration process, ensure the uniform distribution of concrete, and reduce the formation of rough surfaces; at the same time, the support structure increases the sealing of the formwork body 2, reduces the gaps and leakage between the formwork bodies 2, and the good sealing prevents the concrete slurry from being lost from the formwork joints, thereby ensuring the pouring quality; furthermore, the support assembly provides additional fixation and support for the formwork body 2, ensuring that the formwork body 2 is not easy to shake during the vibration process, so that the vibration can more effectively transmit the vibration force to the interior of the concrete, improve the vibration effect, and reduce the formation of bubbles and voids; in addition, the support assembly enables the formwork body 2 to withstand a larger pouring pressure, so that the pouring operation can be carried out in layers and sections, and the vibration of the layered pouring structure can better eliminate bubbles in the concrete, further avoiding the appearance of rough surfaces.
[0034] Furthermore, the support assembly shown includes multiple first support frames 5, multiple second support frames 6 and multiple third support frames 7; multiple first support frames 5 extend along a first direction, which is parallel to the pressure surface; multiple second support frames 6 extend along a second direction, which is parallel to the pressure surface and perpendicular to the first direction; multiple third support frames 7 extend along a third direction, which is perpendicular to the pressure surface; the ends of the first support frames 5 are respectively connected to the ends of the second support frames 6 and the third support frames 7 to form a quadrangular prism frame structure.
[0035] Specifically, the support assembly is a self-detachable frame structure, and the support assembly is formed by splicing a plurality of the first support frames 5, a plurality of the second support frames 6, and a plurality of the third support frames 7; when spliced, the first support frames 5 and the second support frames 6 are perpendicular to each other and parallel to the pressure surface, and the third support frames 7 are perpendicular to the pressure surface; through the free combination of the plurality of the first support frames 5, the plurality of the second support frames 6, and the plurality of the third support frames 7, a quadrangular prism frame structure can be assembled, and the quadrangular prism frame structure abuts against the pressure surface of the formwork body 2 to maintain the stability of the formwork body 2 during the pouring process. The ends of the first support frames 5, the second support frames 6, and the third support frames 7 are all detachably connected, which makes the support assembly an assembled structure. When not in use, the support assembly can be disassembled for easy storage and transportation, and then spliced when needed; the shape and size of the support assembly can be adaptively adjusted according to the size of the formwork body 2. Since the support assembly is a detachable frame structure, when one of the first support frame 5, the second support frame 6 or the third support frame 7 is damaged, it only needs to be replaced separately, avoiding the problem of the entire support assembly being unusable.
[0036] Furthermore, the support assembly also includes a first corner mounting member 8 and a second corner mounting member 9. The first corner mounting member 8 is arranged on the side of the quadrangular prism frame structure close to the template body 2, and the second corner mounting member 9 is arranged on the side of the quadrangular prism frame structure away from the template body 2. The first corner mounting member 8 and the second corner mounting member 9 are both connected to the intersection of the first support frame 5, the second support frame 6 and the third support frame 7.
[0037] Specifically, the first corner mounting member 8 and the second corner mounting member 9 are used to connect the first support frame 5, the second support frame 6 and the third support frame 7. Figure 2 The first corner mounting member 8 includes three mutually perpendicular first mounting portions 13. The first mounting portion 13 is provided with an opening. The first support frame 5, the second support frame 6 and the third support frame 7 can be connected to the first mounting portion 13 by plugging into the opening. Figure 4 The second corner mounting member 9 includes three mutually perpendicular second mounting portions 14, each of which has an opening. The first support frame 5, the second support frame 6, and the third support frame 7 can be connected to the second mounting portion 14 by plugging into the opening. During installation, the first corner mounting members 8 are arranged corresponding to the four corners of the template body 2, and the edges of the first corner mounting members 8 are flush with the edges of the template body 2.
[0038] Furthermore, the support portion 4 is provided on the first corner mounting member 8 , and the support portion 4 is formed with a support surface 10 abutting against the pressure surface; corresponding connection holes are provided on the support portion 4 and the template body 2 .
[0039] Specifically, refer to Figure 3 The support portion 4 is provided on one side of the first corner mounting member 8 for contacting the formwork body 2. The support portion 4 is a flat plate structure and is in close contact with the first corner mounting member 8. The side of the support portion 4 away from the first corner mounting member 8 forms a support surface 10. When installed, the support surface 10 is in close contact with the pressure surface. The support portion 4 increases the contact area between the first corner mounting member 8 and the pressure surface, thereby improving the stability of the support for the formwork body 2 and achieving balanced pressure on the formwork body 2. The support portion 4 is provided with connecting holes, which correspond to the mounting holes at the four corners of the formwork body 2. The support portion 4 is connected to the formwork body 2 by bolts passing through the connecting holes and the mounting holes.
[0040] Furthermore, an elastic shock-absorbing pad is provided on the support surface 10 .
[0041] Specifically, the elastic shock-absorbing pad can be made of rubber material, and the elastic shock-absorbing pad is used for buffering and reducing vibration between the template body 2 and the support part 4.
[0042] Furthermore, the support assembly further includes a transition mounting member 11, which connects the two first support frames 5 or the two second support frames 6 or the two third support frames 7 on the same straight line and connects the other two support frames.
[0043] Specifically, the transition mounting member 11 is used to connect two adjacent first support frames 5 or two adjacent second support frames 6 or two adjacent third support frames 7 on the same straight line. Figure 5 The transition mounting member 11 is provided with four third mounting portions 15, each of which has an opening. Two of the four third mounting portions 15 are collinear and have openings in opposite directions, while the other two third mounting portions 15 are perpendicular to each other and the two collinear third mounting portions 15. The first support frame 5, the second support frame 6, and the third support frame 7 can be connected to the third mounting portions 15 by inserting them into the openings. The provision of the transition mounting member 11 allows the size of the support assembly to be expanded, while the support strength of the support assembly is improved by connecting the first support frame 5, the second support frame 6, and the third support frame 7.
[0044] Furthermore, through holes 12 are provided on the first support frame 5 , the second support frame 6 and the third support frame 7 for reinforcement by bolts.
[0045] Specifically, by setting the through hole 12, two adjacent first support frames 5 or two adjacent second support frames 6 or two adjacent third support frames 7 that are parallel to each other and not collinear can be locked by adding bolts, thereby further improving the structural strength of the support assembly.
[0046] Furthermore, the first support frame 5 , the second support frame 6 and the third support frame 7 are hollow structures.
[0047] Specifically, the first support frame 5, the second support frame 6 and the third support frame 7 are all made of steel and are hollow square tube structures. The hollow setting makes the first support frame 5, the second support frame 6 and the third support frame 7 supportive while reducing weight, thereby facilitating assembly, disassembly and transportation.
[0048] Furthermore, the spacer rod 1 is a hollow PVC tube.
[0049] Specifically, the spacer rod 1 plays a limiting role when assembling the plain concrete formwork. When the plain concrete formwork is demoulded after the plain concrete is formed, the spacer rod 1 is disassembled from the formwork body 2. The spacer rod 1 is buried inside the plain concrete and can be used for drainage of plain concrete components.
