Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge traffic construction, in particular to a template supporting device for a circular pipe culvert seat. Background Art

[0002] As a common drainage structure in road engineering, the main function of circular culverts is to guide water flow through the road and ensure the stability and safety of the road. As an important component of circular culverts, the construction quality of the pipe seat is directly related to the service life and safety of the circular culvert. The pipe seat is usually formed by casting using a formwork. However, the use of traditional wooden formwork, wooden support or steel pipe support to cast the pipe seat has problems such as difficult installation, cumbersome procedures, high consumption of materials such as screws and wires, and long construction period. In addition, the stability of the traditional support system is poor, and the concrete is prone to uneven edges, bulging molds, and misalignment during the casting process. At the same time, it is difficult to apply to larger working surfaces and slopes with different slope coefficients, which affects the straightness and verticality of the concrete casting and increases the difficulty of concrete casting. Utility Model Content

[0003] One of the purposes of the present invention is to provide a supporting device for a circular pipe culvert seat, so as to solve the problem of poor stability of the template supporting system of the circular pipe culvert seat in the prior art.

[0014] According to the above technical means, the ribs increase the strength of the formwork body, so that the square timber is more firmly installed on the formwork body.

[0015] Furthermore, each of the first telescopic assemblies includes a first telescopic body and a hinge support, the hinge support is fixed on the slope, and one end of the first telescopic body is rotatably disposed on the slope through the hinge support.

[0020] According to the above technical means, the fixing part can prevent the second telescopic assembly from falling from the steel formwork.

[0021] Furthermore, each of the second telescopic assemblies further includes a jacking support, which is mounted on the other end of the second telescopic body, and the other end of the second telescopic assembly is supported on the outer wall of the circular culvert through the jacking support.

[0022] According to the above technical means, the contact area between the second telescopic component and the circular culvert is increased, so that the second telescopic component can support the circular culvert more stably.

[0023] Furthermore, a buffer layer is provided on a side of the jacking support close to the circular pipe culvert, and the surface of the circular pipe culvert is in contact with the buffer layer.

[0024] According to the above technical means, the deformation characteristics of the buffer layer are utilized so that the jacking can be used for the circular culvert sections with different pipe diameters.

[0036] The following will refer to the accompanying drawings and preferred embodiments to illustrate the implementation of the present invention.

It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0037] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0038] This embodiment provides Figures 1 to 6The formwork support device for a circular culvert seat shown in the figure comprises a circular culvert 100 and steel formworks 200 arranged on both sides of the circular culvert 100 for pouring, and also comprises at least two first telescopic assemblies 300 and at least two second telescopic assemblies 400; one end of each first telescopic assembly 300 is used to be fixed on the slope, and the other end is supported on each steel formwork 200; one end of each second telescopic assembly 400 is detachably fixed on each steel formwork 200, and the other end is supported on the outer wall of the circular culvert 100.

[0039] In the specific casting construction of the circular culvert seat, firstly, according to the design drawings, the steel formwork 200 is arranged on both sides of the length direction of the circular culvert 100, and then the first telescopic component 300 and the second telescopic component 400 are respectively arranged on the two sides of the steel formwork 200 to ensure that the support device is stable and reliable and can withstand the pressure generated during the casting process, thereby ensuring that the flatness and verticality of the steel formwork 200 meet the design requirements. These first telescopic components 300 and the second telescopic components 400 can be adjusted as needed to achieve multi-point stable support for the steel formwork 200. After the steel formwork 200 is built, the layered casting method is adopted. When casting, it should start from one end and gradually move forward to ensure the uniformity and density of the concrete. Finally, after the concrete strength reaches the design requirements, the steel formwork 200 can be removed to complete the casting of the pipe seat.

[0040] This embodiment provides multi-point support for the steel formwork 200, thereby improving the stability of the supporting device. Moreover, since each first telescopic component 300 and each second telescopic component 400 can be extended and shortened, corresponding adjustments can be made on excavation surfaces of different sizes. When the excavation surface is small or large, each first telescopic component 300 and / or second telescopic component 400 is shortened or extended, so that the formwork supporting device can support the steel formwork 200 on slopes with different excavation widths and different slope coefficients.

[0041] Through the above technical means, the formwork support device of this embodiment has high versatility. At the same time, the formwork support device of this embodiment is a detachable structure, which is convenient to construct and reusable, thereby improving the efficiency of concrete pouring construction, reducing the use of auxiliary materials such as screws and nails, and avoiding the occurrence of nail punctures during construction.

When pouring the pipe seat outside the circular culvert, the steel formwork 200 needs to withstand a large lateral pressure due to the fluidity of the concrete and the pouring pressure. By installing the square timber 220, this solution can effectively enhance the overall rigidity of the steel formwork 200 and prevent the steel formwork 200 from deformation or displacement during the pouring process.

[0044] like Figure 5 As shown, each steel formwork 200 in this embodiment further includes a connecting piece 230, and the square timber 220 is detachably mounted on the formwork body 210 through the connecting piece 230.
