Description

Technical Field

[0001] This utility model belongs to the field of formwork support construction technology, and in particular relates to a positioning device for tie rod holes in beam formwork. Background Technology

[0002] In construction, formwork is frequently used, such as in ditch construction, where concrete is poured after formwork is erected. During formwork construction, to maintain stability between the formwork panels and prevent them from wobbling, loosening, or bulging when concrete is poured into them, a common practice is to install tie rods between the formwork panels. These tie rods support and tighten the formwork, thus improving its stability.

[0003] Before installing the tie rod, threaded holes need to be drilled on both sides of the template, and the threaded holes on both sides need to be aligned on the same straight line. This ensures that the two ends of the tie rod can be accurately threaded into the threaded holes on both sides of the template during operation.

[0004] However, in actual work, it was found that when operators drilled threaded holes on the template, they could not keep the threaded holes on both sides of the template in the same straight line position. As a result, during installation, it was difficult for the two ends of the tie rod to be accurately threaded to the threaded holes on both sides of the template.

[0005] The main reason for the above technical defects is that the opening of the threaded holes relies entirely on the operator's experience and visual aiming at the opening position. This leads to misalignment of the threaded holes on the template during the work process, which seriously affects the installation of the tie rod. Utility Model Content

[0006] Based on the above background, the purpose of this utility model is to provide a positioning device for tie rod holes in beam templates.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A beam formwork tie rod hole positioning device includes a hole alignment mechanism disposed between two formwork panels, wherein the hole alignment mechanism includes abutments disposed at intervals on both sides, the abutments being used to abut against the formwork.

[0009] An upper calibration rod is slidably connected between the support frames, and the upper calibration rod can be adjusted up and down relative to the support frames as well as adjusted back and forth in distance.

[0010] The upper calibration rod has two slidably mounted perforated alignment target plate structures at its two ends. The perforated alignment target plate structure includes a slide block slidably connected to the upper calibration rod. The two ends of the slide block are fixedly connected to telescopic adjustment rods. The telescopic adjustment rods are fixedly connected to reference targets, and the reference targets have through holes.

[0011] Preferably, the telescopic adjustment rod includes a sleeve portion fixedly connected to the reference target, a pull rod portion slidably connected to the sleeve portion, and the pull rod portion fixedly connected to the slide block;

[0012] The pull rod is provided with scale markings, which indicate the length of the target movement.

[0013] Preferably, the support frame includes a vertical frame that is slidably connected to the upper calibration rod, and the vertical frame has a vertically arranged first sliding opening, through which the upper calibration rod passes.

[0014] Preferably, the left and right side walls of the vertical frame are respectively provided with a second sliding opening that connects to the first sliding opening, and the upper calibration rod is provided with a third sliding opening. A sliding screw that passes through the second sliding opening is provided in the third sliding opening, and the two ends of the sliding screw are respectively threaded to positioning nuts that are pressed against the two sides of the vertical frame.

[0015] Preferably, the support frame further includes a horizontal sliding structure that is slidably connected to the vertical frame, the horizontal sliding structure including horizontal frames that are slidably connected to the lower ends of the front and rear side walls of the vertical frame respectively.

[0016] Preferably, push-sliding screws are fixedly connected to the lower ends of the front and rear side walls of the vertical frame, and long sliding openings that cooperate with the push-sliding screws are provided on the horizontal frame;

[0017] The push-slide screw passes through the long sliding port, and a compression positioning nut positioned on the horizontal frame is threaded onto the push-slide screw.

[0018] Preferably, the abutment further includes a base fixedly connected to the bottom of the horizontal frame, and the bottom of the base is fixedly connected to an abutment plate that abuts against the template.

[0019] Preferably, the slide block is threaded with a locking bolt that locks and compresses the upper calibration rod.

[0020] Preferably, the upper calibration rod is provided with scale markings.

[0021] This utility model has the following beneficial effects:

[0022] 1. During the operation, the operator places the entire device between the two side templates (such as in a ditch) and abuts the support frame against the template (adjust the two side support frames in advance and keep the upper calibration rod equidistant from the two side support frames), and keeps the upper calibration rod in a horizontal state.

[0023] Simultaneously, the height of the upper calibration rod is adjusted according to the location of the drilled hole. During the adjustment process, the sliding screw slides in the second sliding port, and after adjustment, it is positioned by the positioning nut. This method solves the technical problem of misalignment of the threaded holes in the template during operation. By setting up a support frame and upper calibration rod, the drilling position is corrected, thereby ensuring that the drilled holes on both sides of the template are aligned. This ensures that the tie rods can be accurately installed subsequently.

[0024] 2. During the operation, the operator first adjusts the reference target so that the through hole structure on the reference target is aligned with the opening position on the template. Then, the operator uses a tool such as an electric screwdriver to insert the cutting tool through the through hole structure and perform the opening operation.

[0025] To keep the front and rear reference targets aligned on the same straight line (ensuring the openings on the template are aligned on the same straight line), operators can, as is currently the case, install scale markings on the pull rod to indicate the length of the reference target movement.

[0026] The scale indicates the length of the sleeve extension, which in turn indicates the position of the reference target. This ensures that the reference targets on both sides are in the same straight line. This method allows for more precise hole drilling on the template after the template is set up, and ensures that the hole structures on both sides of the template are in the same straight line, which facilitates the subsequent installation of the tensioning screw.

[0027] 3. The template opening auxiliary device disclosed in this utility model effectively solves the technical defect that the opening positions of the two templates cannot be aligned when opening holes on the template after the traditional formwork is supported. Moreover, the opening method is highly accurate, easy to operate, and greatly improves the opening efficiency. Attached Figure Description

[0037] Example 1

[0038] like Figure 1-4 As shown, a beam formwork tie rod hole positioning device includes a hole alignment mechanism disposed between two formwork panels. The hole alignment mechanism is used to keep the threaded holes on both formwork panels aligned during the hole-making process.

[0039] Specifically, the aperture alignment mechanism includes two spaced-apart supports on both sides, which abut against the template. An upper calibration rod 23 is slidably connected between the supports, and the upper calibration rod 23 can be adjusted vertically and horizontally relative to the supports, as well as its distance from side to side.

[0040] Specifically, the support frame includes a vertical frame 22 that is slidably connected to the upper calibration rod 23. The vertical frame 22 has a vertically arranged first sliding opening B, and the upper calibration rod 23 passes through the first sliding opening B.

[0041] Meanwhile, in order to mark the positional relationship between the upper calibration rod 23 and the two side supports, that is, to determine that the center points of the two side supports and the upper calibration rod 23 are equidistant, scale marks are set on the upper calibration rod 23 in the existing manner.

[0042] The vertical frame 22 has a second sliding opening A on its left and right side walls, which connects to the first sliding opening B. The upper calibration rod 23 has a third sliding opening. A sliding screw 231 that passes through the second sliding opening A is provided in the third sliding opening. The two ends of the sliding screw 231 are respectively threaded with positioning nuts that are pressed against both sides of the vertical frame 22.

[0043] During operation, the operator places the entire device between the two side templates (such as in a ditch) and abuts the support frame against the template (adjust the two side support frames in advance and keep the upper calibration rod 23 equidistant from the two side support frames), and keeps the upper calibration rod 23 in a horizontal state.

[0044] Simultaneously, the height of the upper calibration rod 23 is adjusted according to the location of the drilled hole. During the adjustment process, the sliding screw 231 slides in the second sliding port A, and is then positioned by the positioning nut. This method addresses the technical problem of misalignment of the threaded holes in the template during operation. By setting up a support frame and the upper calibration rod 23, the drilling position is corrected, thereby ensuring alignment of the drilled holes on both sides of the template. This ensures accurate installation of the subsequent tie rods.

[0045] Example 2

[0046] like Figure 1-4 As shown, based on the structure of Embodiment 1, this embodiment further includes a horizontal sliding structure that slidably connects to the vertical frame 22. The horizontal sliding structure includes horizontal frames 21 slidably connected to the lower ends of the front and rear side walls of the vertical frame 22. Specifically, a pair of push-slide screws 221 are fixedly connected to the lower ends of the front and rear side walls of the vertical frame 22, respectively. The horizontal frame 21 has a long sliding opening C that mates with the push-slide screws 221. The push-slide screws 221 pass through the long sliding opening C, and a compression positioning nut positioned on the horizontal frame 21 is threaded onto the push-slide screws 221.

[0047] The aforementioned support frame also includes a base 12 fixedly connected to the bottom of the horizontal frame 21, and the bottom of the base 12 is fixedly connected to an abutment plate 11 that abuts against the template.

[0048] During the operation, once a threaded hole on the template is opened, the two sides of the support frame are pushed to slide to the next threaded hole opening position. After being pushed to the target position, the positioning is achieved by squeezing and locking the positioning nut.

[0049] Example 3

[0050] like Figure 1-4 As shown, in this embodiment, based on the structure of embodiment 2, in order to increase the accuracy of the opening, the two ends of the upper calibration rod 23 are respectively slidably installed with an opening alignment target plate structure 3. The opening alignment target plate structure 3 includes a slide block 31 slidably connected to the upper calibration rod 23. The two ends of the slide block 31 are respectively fixedly connected with a telescopic adjustment rod 32. The telescopic adjustment rod 32 is respectively fixedly connected with a reference target 33. The reference target 33 has a through hole structure 331.

[0051] Meanwhile, the slide block 31 is threaded with a locking bolt 311 that locks and compresses the upper calibration rod 23.

[0052] The telescopic adjustment rod 32 includes a sleeve portion that is fixedly connected to the reference target 33, and a pull rod portion that is slidably connected to the sleeve portion. The pull rod portion is fixedly connected to the slide block 31.

[0053] During the operation, the operator pre-adjusts the reference target 33 until the through hole structure 331 on the reference target 33 is aligned with the opening position on the template. Then, the operator uses a tool such as an electric screwdriver to pass the cutting tool through the through hole structure and perform the opening operation.

[0054] In order to keep the front and rear reference targets 33 in the same straight line (to ensure that the openings on the template are in the same straight line), the operator can, as in the existing method, open scale marks on the pull rod to indicate the length of movement of the reference target 33.

[0055] The scale indicates the length of the sleeve extension, which in turn indicates the position of the reference target 33, ensuring that the reference targets 33 on both the front and rear sides are in the same straight line. In this way, holes can be opened on the template in a more precise manner after the template is set up, and it can be ensured that the opening structure on both sides of the template is in the same straight line, which facilitates the subsequent installation of the tensioning screw.

[0056] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
