Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a supporting device for a cast-in-situ formwork of a strip drainage ditch. Background Art

[0002] Mountain slope protection drainage ditches are used to maintain slope stability and prevent soil erosion. They are typically designed to collect and direct surface runoff away from the slope or roadbed to reduce soil erosion. Slope protection drainage ditches are a crucial component of projects such as road construction, water conservancy projects, and urban greening.

[0003] When constructing a traditional mountain slope protection drainage ditch, two sets of formwork need to be set up to form the inner and outer facades of the drainage ditch. Since the outer side of the inner facade of the drainage ditch is adjacent to the slope, no support formwork is required on this side. Therefore, it is only necessary to support the inner side of the inner facade of the drainage ditch and the inner and outer sides of the outer facade of the drainage ditch.

[0004] However, during the support process of the two sets of formwork, wooden slats need to be installed between the two sets of formwork to achieve support and fixation of the two sets of formwork. However, the installation process of the wooden slats is very inconvenient, which affects the support efficiency of the formwork and reduces the construction efficiency, and needs to be improved.

DETAILED DESCRIPTION

[0025] The present invention will be described in further detail below with reference to the accompanying drawings.

[0026] Example 1:

[0027] like Figure 1 、 Figure 2 As shown, a support device for a cast-in-place formwork of a strip drainage ditch includes a cross bar 1, a pair of support bars 2 and a clamping bar 3.

[0028] like Figure 2 As shown, a crossbar 1 is arranged horizontally, with the crossbar extending between the upper ends of the two sets of formwork. A pair of support rods 2 are vertically mounted on the crossbar 1 and are used to contact the inner wall of the two sets of formwork where they are close to each other. A reinforcement rod 4 is horizontally positioned between the lower ends of the pair of support rods 2 to increase the structural strength between the support rods 2 and ensure stable support of the two sets of formwork.

[0029] like Figure 2 As shown, the clamping rod 3 is vertically arranged at one end of the crossbar 1 and is used to clamp the outer wall of the external template. The lower end of the clamping rod 3 is vertically provided with a spike 5 for piercing the ground to fix the entire support device and increase the stability after installation.

[0030] like Figure 2 As shown, a pressure rod 6 is horizontally extended from one end of the cross bar 1 away from the clamping rod 3. The pressure rod 6 is used to press the upper end surface of the internal template to achieve support for the entire supporting device and increase stability during installation and use.

[0031] When two sets of formwork need to be supported, a pair of support rods 2 are vertically inserted between the two sets of formwork. At this time, the support rods 2 respectively contact the side of the inner and outer formwork that is close to each other. At the same time, the clamping rods 3 clamp the outer side of the outer formwork to support and clamp the two sets of formwork. At the same time, with the cooperation of the pressure rods 6, the entire support device is horizontally supported on the two sets of formwork, increasing the stability of the two sets of formwork during operation.

[0032] Therefore, by setting up a support device that is easy to install, the support and fixation of the two sets of formwork are achieved, the stability of the formwork is increased, and there is no need to nail wooden slats, which simplifies the construction process and improves construction efficiency. At the same time, the entire support device can be easily disassembled and used in a turnover manner, realizing the reuse of the support device, which helps to reduce construction costs.

[0033] Especially in the construction process of curved drainage ditches, if wooden slats are used, diagonal wooden slats need to be laid at the curved position of the template, which makes construction more inconvenient. The use of this support device can not only be installed quickly, but also support the template without destroying the curvature of the template, thereby ensuring the construction quality of the curved drainage ditch.

[0034] Example 2:

[0035] like Figure 3 As shown, the cross bar 1 includes an upper tube body 11 and a pair of upper rod bodies 12, and the pair of upper rod bodies 12 are horizontally slidably connected to the two ends of the upper tube body 11. The reinforcing rod 4 includes a lower tube body 41 and a pair of lower rod bodies 42, and the pair of lower rod bodies 42 are horizontally slidably connected to the two ends of the lower tube body 41.

[0036] like Figure 3 As shown, a driving mechanism 7 for controlling a pair of support rods 2 to move closer to or away from each other is provided between the upper tube body 11 and the lower tube body 41 . The driving mechanism 7 includes a bidirectional screw 71 , a pair of sliders 72 , four driving rods 73 and a hand wheel 74 .

[0037] like Figure 3 As shown, a bidirectional screw rod 71 is vertically rotatably connected between the upper tube body 11 and the lower tube body 41. A handwheel 74 is provided at the upper end of the bidirectional screw rod 71, and a slider 72 is threadedly connected to the upper and lower ends of the bidirectional screw rod 71. Four drive rods 73 are grouped in pairs and rotatably connected to both sides of the slider 72. The two drive rods 73 on the same side are rotatably connected to the middle position of the support rod 2.

[0038] Therefore, when the width of the drainage ditch to be constructed changes, the handle can be rotated to drive the bidirectional screw 71 to rotate synchronously. At this time, the bidirectional screw 71 drives a pair of sliders 72 to move closer to or away from each other, and the slider 72 drives the driving rod 73 to flip. At this time, under the sliding cooperation of the upper tube body 11 and the upper rod body 12 and the lower tube body 41 and the lower rod body 42, a pair of support rods 2 are pushed or pulled to slide relative to each other, thereby realizing the adjustment of the distance between the support rods 2, adapting to the construction requirements of drainage ditches of different widths, and improving the practicality of the entire device.

[0039] Example 3:

[0040] like Figure 4 As shown, the upper end of the clamping rod 3 is provided with a sleeve 8 which is slidably connected to the cross bar 1 , and a bolt 9 which presses the cross bar 1 is threadedly connected to the sleeve 8 .

[0041] Therefore, when the thickness of the facade structure of the drainage ditch to be constructed changes, the bolt 9 can be loosened, and then the sleeve 8 can be pushed to drive the clamping rod 3 to slide horizontally, so as to adjust the distance between the clamping rod 3 and the support rod 2, thereby adapting to the construction requirements of the facade structure of the drainage ditch with different thicknesses and improving the practicality of the entire device.

[0042] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the embodiments as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
