Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a monitoring device for preventing the formwork from bulging during pier body pouring. Background Technique

[0002] Traditionally, monitoring the formwork bulging of cast-in-place concrete depends on construction carpenters. During concrete pouring, they observe with their eyes. When it is found that the formwork bulges, the concrete pouring personnel are immediately notified to stop pouring, and then the formwork support system is repaired. After the formwork support system is repaired, the concrete pouring continues.

[0003] In actual use, it is often found that the formwork bulges far beyond the allowable range, but it is too late, resulting in the geometric dimensions of building components deviating beyond the standard regulations. At the same time, it is also affected by human subjective factors, and the formwork bulging phenomenon during concrete pouring cannot be detected, resulting in the geometric dimensions of building components exceeding the allowable deviation range specified in the code. The monitoring effect is poor, and the formwork bulging cannot be detected in time, so it is not convenient to use. Content of the Utility Model

[0004] Based on the technical problem that the existing device has a poor monitoring effect and cannot detect the formwork bulging in time, the utility model provides a monitoring device for preventing the formwork from bulging during pier body pouring.

[0006] Preferably, the pressure board is located inside the formwork board, and the center of the pressure board is located at the vertex angle of the formwork board.

[0007] Preferably, the surface of the connecting rod is fixedly connected to the surface of the formwork board, and a plurality of the connecting rods are symmetrically distributed with the axis of the pressure board as the center, and the mounting board is coaxially arranged with the pressure board.

[0009] Preferably, the inner wall of the second cylinder body is fixedly communicated with the inner wall of the first cylinder body. The inside of the second cylinder body is filled with liquid. The inner wall of the second cylinder body is slidably connected to the surface of the second piston.

[0010] Preferably, both ends of the tension spring are fixedly connected to the surface of the second cylinder body and the surface of the second push plate respectively. The surface of the second push plate is slidably connected to the surface of the scale.

[0011] The beneficial effects of the present utility model are as follows:

[0012] By setting the first cylinder body and the second cylinder body to be fixedly communicated, and the surface area of the first piston being larger than the surface area of the second piston, the minute deformation generated by the mold plate in contact with the first push plate is amplified, resulting in a larger displacement change, which can be easily detected by the distance that the second push plate slides on the surface of the scale, solving the technical problem that the existing device has a poor monitoring effect and cannot detect mold swelling in time.

Detailed Embodiments

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0018] Refer to Figures 1-3, a monitoring device for preventing the formwork from bulging during pier casting, including a formwork 1, a pressure plate 2 fixedly connected to the surface of the formwork 1, a connecting rod 3 fixedly connected to the surface of the pressure plate 2, a mounting plate 4 fixedly connected to the surface of the connecting rod 3, a first cylinder 5 fixedly connected to the surface of the mounting plate 4, a first piston 6 arranged inside the first cylinder 5, a first push rod 7 fixedly connected to the surface of the first piston 6, a first push plate 8 fixedly connected to the surface of the first push rod 7, a second cylinder 9 arranged on the surface of the first cylinder 5, a scale 10 fixedly connected to the surface of the second cylinder 9, a second piston 11 arranged inside the second cylinder 9, a second push rod 12 fixedly connected to the surface of the second piston 11, a second push plate 13 fixedly connected to the surface of the second push rod 12, and a tension spring 14 arranged outside the second push rod 12.

[0019] The pressure plate 2 is located inside the formwork 1, and the center of the pressure plate 2 is located at the vertex of the formwork 1.

[0020] Furthermore, the corners of the casting formwork 1 are prone to bulging, and the vertex of the pressure plate 2 is the center of the formwork 1.

[0021] The surface of the connecting rod 3 is fixedly connected to the surface of the formwork 1. A plurality of connecting rods 3 are symmetrically distributed around the axis of the pressure plate 2, and the mounting plate 4 is coaxially arranged with the pressure plate 2.

[0022] Furthermore, the axis of the mounting plate 4 and the vertex of the formwork 1 are on the same axis.

[0023] The first cylinder 5 is located at the center of the mounting plate 4. The inside of the first cylinder 5 is filled with liquid. The inner wall of the first cylinder 5 is slidably connected to the surface of the first piston 6. The surface of the first push plate 8 is movably connected to the surface of the formwork 1.

[0024] Furthermore, when the surface of the formwork 1 deforms, the first push plate 8 and the first push rod 7 drive the first piston 6 to slide along the inner wall of the first cylinder 5.

[0025] The inner wall of the second cylinder 9 is fixedly communicated with the inner wall of the first cylinder 5. The inside of the second cylinder 9 is filled with liquid. The inner wall of the second cylinder 9 is slidably connected to the surface of the second piston 11.

[0026] Furthermore, the surface of the second piston 11 pushes the surface of the first piston 6 through the liquid filled in the inside of the first cylinder 5 and the inside of the second cylinder 9.

[0027] Both ends of the tension spring 14 are fixedly connected to the surface of the second cylinder 9 and the surface of the second push plate 13 respectively. The surface of the second push plate 13 is slidably connected to the surface of the scale 10.

[0028] Furthermore, the tension spring 14 pulls the second push plate 13 tightly, causing the surface of the first push plate 8 to be in close contact with the surface of the mold plate 1.

[0029] By setting the first cylinder block 5 and the second cylinder block 9 to be fixedly connected and the surface area of the first piston 6 to be larger than the surface area of the second piston 11, the minute deformation generated by the mold plate 1 in contact with the first push plate 8 is amplified, resulting in a larger displacement change. The distance that the second push plate 13 slides on the surface of the scale 10 is easy to detect in a timely manner, solving the technical problem that the monitoring effect of the existing device is poor and the mold swelling cannot be detected in a timely manner.

[0030] Working principle:

[0031] Before use, the pressure plate 2 is fixed inside the mold plate 1, and the center of the pressure plate 2 is located at the vertex angle where multiple mold plates 1 are connected. The connecting rod 3 passes through the surface of the mold plate 1 and is fixedly connected to the surface of the mounting plate 4. The first cylinder block 5 is fixedly installed at the center position of the mounting plate 4, and the inner wall of the first cylinder block 5 is fixedly connected to the inner wall of the second cylinder block 9. The surface of the mold plate 1 is provided with a first push plate 8, and the center of the first push plate 8 and the vertex angle of multiple mold plates 1 are on the same axis. When the mold plate 1 deforms, the surface of the mold plate 1 drives the first piston 6 to slide along the inner wall of the first cylinder block 5 through the first push plate 8 and the first push rod 7, pushing the liquid inside the first cylinder block 5 into the inside of the second cylinder block 9 to drive the second piston 11 to slide along the inner wall of the second cylinder block 9. The second piston 11 drives the second push plate 13 to slide along the surface of the scale 10 through the second push rod 12. The surface of the second push plate 13 is elastically connected to the surface of the second cylinder block 9 through the tension spring 14, causing the surface of the first push plate 8 to be in close contact with the surface of the mold plate 1. The surface area of the first piston 6 is larger than the surface area of the second piston 11, and the minute deformation that occurs on the surface of the mold plate 1 is transmitted to the second push plate 13 through the first push plate 8, resulting in a larger displacement, which is convenient to be clearly shown on the scale of the scale 10.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
