Description

Technical Field

[0001] This utility model relates to the field of construction technology of intercepting ditch on road cut slope platform, and more specifically to a formwork support structure for intercepting ditch on cast-in-place platform of road cut slope. Background Technology

[0002] A slope intercepting ditch is a drainage ditch dug on a hillside or steep slope to divert rainwater, snowmelt, and other water from the hillside into a channel below, thereby achieving the purpose of waterproofing and flood control.

[0003] Slope intercepting ditch support structures are essential tools for constructing intercepting ditches. A utility model patent with application number 202121614795.7 discloses a slope platform intercepting ditch support structure, including a support frame and a template assembly that cooperates with the support frame. Multiple support frames are arranged at intervals along the extension direction of the slope platform. One side of each support frame forms a slope support surface that cooperates with the slope, and the side of the support frame opposite the slope support surface is configured as a template support surface that cooperates with the template assembly. The template assembly is embedded in the template support surface and concrete is poured into it, forming an intercepting ditch between it and the slope on the other side. However, during construction, the irregular shape of the working surface at the slope platform increased the difficulty of controlling the installation accuracy and stability of the formwork. Furthermore, the support frame can only be used for the construction of intercepting ditches with specific cross-sectional dimensions. The turnover efficiency and number of transfers of the formwork after construction are not high. For intercepting ditches with different cross-sectional dimensions, it is necessary to remake support frames that meet the dimensions, resulting in multiple wastes of manpower, time, and materials.

[0004] Therefore, how to provide a drainage ditch template support structure that is easy to install and reusable and can be applied to different cross-sectional size requirements is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention aims to provide a formwork support structure for the intercepting ditch of the cast-in-place platform on the road cut slope to at least to some extent solve the problem that the working surface at the slope platform has an irregular shape, which increases the difficulty of formwork installation accuracy and stability control. Moreover, the support frame can only be used for the construction of intercepting ditches with specific cross-sectional dimensions. After construction, the formwork turnover efficiency and the number of transfers are not high. For intercepting ditches with different cross-sectional dimensions, it is necessary to remake support frames that meet the dimensions, resulting in multiple wastes of manpower, time and materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A formwork support structure for a cast-in-place platform drainage ditch on a road cut slope includes: a formwork assembly, a slope protection plate, and a support frame. The formwork assembly includes a front formwork and a rear formwork, which are spaced apart along a direction away from the slope. The space between the front and rear formwork is a concrete pouring space, and the concrete poured in the concrete pouring space forms the drainage ditch with the slope. The slope protection plate is supported on the lower sidewall of the slope. Multiple support frames are provided and spaced apart along the length of the slope. Each set of support frames includes:

[0008] A positioning beam, one end of which is supported on the slope protection plate, and the other end is connected to the top of the rear template through a positioning component;

[0009] An adjustable-length inner support beam is provided, which is supported between the front template and the rear template.

[0010] An adjustable external clamping assembly includes a fixed longitudinal beam, a sliding longitudinal beam, and a connecting rod. The fixed longitudinal beam and the sliding longitudinal beam abut against the front template and the rear template, which are located far apart from each other, to clamp the front template and the rear template within the clamping cavity formed by the fixed longitudinal beam and the sliding longitudinal beam. The connecting rod is positioned above the front template and the rear template, with one end fixedly connected to the fixed longitudinal beam and the other end slidably connected to the sliding longitudinal beam and fixed by a locking member. Its sliding direction is along the arrangement direction of the front template and the rear template.

[0011] The beneficial effects achievable by this invention are as follows: This structure utilizes slope protection panels to cover uneven slopes, creating a smoother support surface for installing the support frame. The support frame dimensions are more uniform, making installation easier, and minimizing disturbance to the formwork during concrete pouring. The rear formwork is positioned using positioning beams, while the front formwork is fixed after adjusting its relative position to the rear formwork using adjustable-length internal support beams and adjustable external clamping components. This allows for easy adjustment of the concrete cross-sectional dimensions and facilitates the reuse of the support frame.

[0012] Preferably, the positioning beam has multiple adjustment holes spaced apart along the direction away from the slope protection plate, and the positioning member can pass through the adjustment holes and be fixed to the top of the rear template.

[0013] Preferably, the locking component includes a positioning pin, and the connecting rod has a plurality of positioning holes spaced apart along the direction of the front template and the rear template, and the positioning pin is positioned and inserted into the positioning holes.

[0015] Preferably, the support frame further includes a first outer support beam, one end of which is supported at the bottom of the connection between the sliding longitudinal beam and the connecting rod, and the other end slopes downward away from the rear template to support the ground.

[0016] Preferably, the support frame further includes a second outer support beam, the two ends of which are respectively supported between the lower side wall of the front template and the lower side wall of the slope protection plate.

[0017] Preferably, the second outer support beam slopes downwards in a direction close to the slope protection plate.

[0018] Preferably, the slope protection plate includes a main plate, a first connecting plate, and a second connecting plate. The first connecting plate is fixed to the upper part of the main plate; the second connecting plate is fixed to the lower part of the main plate; the top of the positioning beam at the end away from the rear template abuts against the bottom surface of the first connecting plate; and the bottom of the second outer support beam at the end away from the front template abuts against the top surface of the second connecting plate.

[0019] Preferably, the front template and the rear template have the same structure, both including a template main board, an upper connecting plate, and a lower connecting plate. The two template main boards on the front template and the rear template are arranged opposite to each other. The upper connecting plates are respectively fixed to the upper parts of the two mutually distant plate surfaces of their template main boards. The two lower connecting plates are respectively fixed to the lower parts of the two mutually distant plate surfaces of their template main boards and supported on the ground. The end of the positioning beam away from the slope protection plate is fixed to the upper connecting plate on the rear template through the positioning member.

[0020] Preferably, inclined pads are fixed on the main plates of the front template and the rear template that are far apart from each other. One end of the inclined pad is fixed to the corresponding main plate of the template, and the other end is inclined downward along the length of the slope protection plate.

[0022] 1. This structure utilizes slope protection panels to cover uneven slopes, creating a smoother support surface for installing support frames. The support frames are more uniform in size, easier to install, and have less impact on formwork disturbance during concrete pouring.

[0023] 2. The rear template is positioned and installed using a positioning beam, and its position relative to the positioning beam is adjustable. The front template is fixed after its relative position to the rear template is adjusted using an adjustable length inner support beam and an adjustable outer clamping assembly. This makes it easy to adjust the cross-sectional dimensions of the intercepting ditch and to reuse the support frame.

[0024] 3. Use the first and second external support beams for auxiliary support to enhance the overall strength of the structure and reduce the disturbance to the formwork during the concrete pouring process. Attached Figure Description

[0033] Please see Figures 1-4 This utility model embodiment discloses a formwork support structure for a cut slope cast-in-place platform intercepting ditch, including: a formwork assembly 1, a slope protection plate 2, and a support frame 3;

[0034] Template assembly 1 includes a front template 11 and a rear template 12, which are spaced apart along the direction away from the slope 4, and the space between the front template 11 and the rear template 12 is a concrete pouring space. The concrete poured in the concrete pouring space forms a drainage ditch with the slope 4. Slope protection plate 2 is supported on the lower side wall of the slope 4. Multiple support frames 3 are provided and spaced apart along the length of the slope 4. Each set of support frames 3 includes:

[0035] Positioning beam 31, one end of which is supported on the slope protection plate 2, and the other end is connected to the top of the rear formwork 12;

[0036] An adjustable length inner support beam 32 is provided between the front template 11 and the rear template 12.

[0037] The adjustable external clamping assembly 33 includes a fixed longitudinal beam 331, a sliding longitudinal beam 332, and a connecting rod 333. The fixed longitudinal beam 331 and the sliding longitudinal beam 332 abut against the front template 11 and the rear template 12, which are far apart from each other, so as to clamp the front template 11 and the rear template 12 in the clamping cavity formed by the fixed longitudinal beam 331 and the sliding longitudinal beam 332. The connecting rod 333 is placed above the front template 11 and the rear template 12, with one end fixedly connected to the fixed longitudinal beam 331 and the other end slidably connected to the sliding longitudinal beam 332 and fixed by the locking member 334. Its sliding direction is along the arrangement direction of the front template 11 and the rear template 12.

[0038] This structure utilizes slope protection panels 2 to cover the uneven slope 4, creating a smoother support surface for installing the support frame 3. The support frame 3 has more uniform dimensions, is easier to install, and has less impact on the formwork during concrete pouring. The rear formwork 12 is positioned by positioning beams 31, and the front formwork 11 is fixed after adjusting its relative position to the rear formwork 12 using adjustable-length inner support beams 32 and adjustable outer clamping components 33. This allows for easy adjustment of the concrete cross-sectional dimensions, and the support frame 3 is easily reusable.

[0039] Specifically, the positioning beam 31 has multiple adjustment holes 311 spaced apart along the direction away from the slope protection plate 2. The positioning component can pass through the adjustment holes 311 and be fixed to the top of the rear template 12. The positioning component can be a bolt and nut assembly or screws, etc., so that by adjusting the position of the positioning component, it can be adapted to drainage ditches of different widths.

[0040] Specifically, the locking component 334 includes a positioning pin, and the connecting rod 333 has multiple positioning holes 3331 spaced apart along the direction of the front template 11 and the rear template 12. The positioning pin is inserted into the positioning holes 3331. The position of the sliding longitudinal beam 332 can be quickly positioned by using the positioning pin and the positioning holes 3331, thereby adjusting the distance between the front and rear templates 12.

[0041] Specifically, the positioning hole 3331 is an elongated hole arranged along the length of the front template 11 and the rear template 12, and the diameter of the positioning pin gradually increases in the direction away from the elongated hole. The positioning pin is a tapered pin, and its insertion length can be adjusted to suit the sliding longitudinal beam 332 at different positions.

[0042] Specifically, the support frame 3 also includes a first outer support beam 34. One end of the first outer support beam 34 is supported at the bottom of the connection between the sliding longitudinal beam 332 and the connecting rod 333, and the other end slopes downward away from the rear template 12 to support it on the ground, further reinforcing the rear template 12 and preventing the rear template 12 from shifting.

[0043] Specifically, the support frame 3 also includes a second outer support beam 35, the two ends of which are respectively supported between the lower side wall of the front template 11 and the lower side wall of the slope protection plate 2, further reinforcing the front template 11 and preventing the front template 11 from shifting.

[0044] Specifically, the second outer support beam 35 slopes downwards along the direction close to the slope protection plate 2 to enhance the stability of the support.

[0045] Specifically, the slope protection plate 2 includes a main plate 21, a first connecting plate 22, and a second connecting plate 23. The first connecting plate 22 is fixed to the upper part of the main plate 21; the second connecting plate 23 is fixed to the lower part of the main plate 21; the top of the positioning beam 31 at the end away from the rear template 12 abuts against the bottom surface of the first connecting plate 22; the bottom of the second outer support beam 35 at the end away from the front template 11 abuts against the top surface of the second connecting plate 23. This further strengthens the overall structure of the slope protection plate 2, as well as the stability of the positioning beam 31 and the second outer support beam 35.

[0046] Specifically, the front template 11 and the rear template 12 have the same structure, both including a template main plate 111, an upper connecting plate 112, and a lower connecting plate 113. The two template main plates 111 on the front template 11 and the rear template 12 are arranged opposite to each other. The upper connecting plates 112 are respectively fixed to the upper parts of the two mutually distant plates of their template main plates 111; the two lower connecting plates 113 are respectively fixed to the lower parts of the two mutually distant plates of their template main plates 111 and supported on the ground; the end of the positioning beam 31 away from the slope protection plate 2 is fixed to the upper connecting plate 112 on the rear template 12 by a positioning component. This strengthens the template main plate 111 and facilitates installation.

[0047] Specifically, inclined pads 114 are fixed on the far sides of the main template 111 of the front template 11 and the rear template 12. One end of the inclined pad 114 is fixed on the corresponding main template 111, and the other end is inclined downward along the length of the slope protection plate 2. The lower ends of the sliding longitudinal beam 332 and the fixed longitudinal beam 331 abut against the corresponding inclined pads 114, which can accommodate sliding longitudinal beams 332 and fixed longitudinal beams 331 of different lengths.

Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
