Abstract

This application discloses a monitoring device for continuously monitoring the concrete stopping surface, including a fixing plate on one side of a frame, a clamping and fixing assembly for fixing to the frame on one side of the fixing plate, a connecting seat on the other side of the fixing plate, a steel wire rope at the bottom of the connecting seat, a suspended ball at the bottom of the steel wire rope, and a winding assembly inside the connecting seat for moving the suspended ball up and down. The suspended ball reaches the stopping surface position at the top of the concrete by the downward movement of the steel wire rope. When the concrete is poured, the suspended ball, which has a density lower than the concrete but higher than the slurry, can suspend with the pouring of the concrete and always remain at the stopping surface position. By rotating the knob, the steel wire rope is kept in a vertically taut state, and the position of the stopping surface is measured according to the scale lines on the steel wire rope, so that the position of the stopping surface can be monitored at any time.

Description

Technical Field

[0001] This application relates to the field of pile foundation construction, and in particular to a monitoring device for continuously monitoring the concrete mortar surface. Background Technology

[0002] If concrete pouring is suspended due to equipment failure, material supply interruption, or construction organization problems, the surface of the poured concrete will form a specific surface layer, namely the grout stop surface, because the cement slurry stops flowing. When carrying out pile foundation construction, it is necessary to monitor the grout stop surface to ensure that the concrete is poured in layers according to the design elevation, avoid over-pouring or under-pouring, and reduce cold joints caused by interruption.

[0003] However, during the implementation of the relevant technical solutions, at least the following technical problems were found: the existing control of the pile foundation mortar stopping surface relies entirely on direct visual observation, which is very inaccurate; after the installation of the guide pipe, the line of sight at the mortar stopping surface is dark, which is not conducive to observing the height of the mortar stopping surface; there is mud and water above the mortar stopping surface, making it impossible to accurately determine the specific location of the mortar stopping surface; and it is also difficult to continuously monitor the height of the mortar stopping surface using measuring ropes, which may miss the best time and affect the accuracy of the mortar stopping surface monitoring. Utility Model Content

[0004] This application provides a monitoring device for continuously monitoring the concrete mortar surface, which solves the problem of difficulty in monitoring the mortar surface in the prior art, and achieves the effect of keeping the suspended ball flush with the mortar surface to monitor the height of the mortar surface.

[0005] This application provides a monitoring device for continuous monitoring of concrete ash-stopping surfaces, including a fixing plate on one side of a frame, a clamping and fixing assembly for fixing the fixing plate on one side, a connecting seat on the other side of the fixing plate, a steel wire rope at the bottom of the connecting seat, a suspended ball at the bottom of the steel wire rope, and a winding assembly for driving the suspended ball up and down inside the connecting seat.

[0006] Furthermore, the density of the suspended sphere is higher than that of the mud, and the density of the suspended sphere is lower than that of the concrete.

[0007] Furthermore, the suspended sphere is provided with scale lines.

[0008] Furthermore, a groove is formed in the middle of one side of the fixing plate, and the clamping and fixing assembly includes: a guide rail, fixedly disposed inside the groove; a fixing seat, fixedly disposed in the middle of the guide rail; two movable blocks, respectively sleeved and slidably connected to the two ends of the outer side of the guide rail; a clamping plate, disposed on one side of the movable block, and the two clamping plates respectively contact and connect with the top and bottom of the frame plate; and a spring, sleeved on the outer side of the guide rail, and the spring is disposed between the fixing seat and the movable block.

[0009] Furthermore, the connecting seat has an internal cavity, and the bottom of the cavity has a through groove, through which the steel wire rope extends into the cavity.

[0010] Furthermore, the winding assembly includes: two connecting plates, respectively disposed on both sides of the cavity; a rotating shaft, rotatably connected between the two connecting plates, with the top end of the wire rope wound around the outside of the rotating shaft; and a knob disposed at the outer end of the rotating shaft extending from the connecting seat.

[0011] The technical solution provided in this application has at least the following technical effects or advantages:

[0012] The suspension ball is lowered by the steel wire rope to reach the mortar stop position at the top of the concrete. When the concrete is poured, the suspension ball, which has a density lower than the concrete but higher than the mud, can suspend along with the concrete and always stay at the mortar stop position. The steel wire rope is kept vertically taut by rotating the knob. The position of the mortar stop is measured according to the scale line on the steel wire rope, so the position of the mortar stop can be monitored at any time. Attached Figure Description

Detailed Implementation

[0020] This application discloses a monitoring device for continuously monitoring the concrete mortar surface. By rotating the knob 73, the suspension ball 60 at the bottom of the wire rope 50 is lowered, and the suspension ball 60 contacts the mortar surface at the top of the concrete. As the concrete is poured, the mortar surface rises, and the suspension ball 60 suspends with the mortar surface. Rotating the knob 73 tightens the wire rope 50 to a taut position, thereby continuously monitoring the mortar surface.

[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0022] Please refer to Figure 1 and Figure 2 This embodiment provides a monitoring device for continuously monitoring the concrete mortar surface, including a fixing plate 20 on one side of a support plate 10. A clamping and fixing assembly 40 for fixing to the support plate 10 is provided on one side of the fixing plate 20. A connecting seat 30 is provided on the other side of the fixing plate 20. A steel wire rope 50 is provided at the bottom of the connecting seat 30. A suspended ball 60 is provided at the bottom of the steel wire rope 50. A winding assembly 70 for moving the suspended ball 60 up and down is provided inside the connecting seat 30. The density of the suspended ball 60 is higher than that of the mud and lower than that of the concrete. The suspended ball 60 is provided with scale lines. Through the stretchable and retractable steel wire rope 50 at the bottom of the connecting seat 30, the suspended ball 60 at the bottom of the steel wire rope 50 can move down to the mortar surface at the top of the concrete. When the mortar surface rises due to concrete pouring, the suspended ball 60, whose density is lower than that of the concrete but higher than that of the mud, can rise with the concrete pouring and always be at the same height as the mortar surface. The position of the concrete mortar surface can be monitored by observing the position of the suspended ball 60.

[0023] Please refer to Figures 1-5A groove 21 is provided in the middle of one side of the fixing plate 20. The clamping and fixing assembly 40 includes a guide rail 41, a fixing seat 42, a movable block 43, a clamping plate 44, and a spring 45. The guide rail 41 is fixedly disposed inside the groove 21, and the fixing seat 42 is fixedly disposed in the middle of the guide rail 41. Two movable blocks 43 are respectively sleeved and slidably connected to the two ends of the outer side of the guide rail 41. The clamping plate 44 is disposed on one side of the movable block 43, and the two clamping plates 44 are respectively in contact with the top and bottom of the frame plate 10. The spring 45 is sleeved on the outer side of the guide rail 41. Furthermore, the spring 45 is positioned between the fixed seat 42 and the movable block 43. The elastic force of the spring 45 drives the two movable blocks 43 to move towards the center, thereby causing the two clamping plates 44 to move towards each other. This allows the two clamping plates 44 to be tightly attached to the top and bottom of the frame plate 10, fixing the fixed plate 20 to the frame plate 10 for monitoring the concrete mortar surface at the bottom. Pulling out the two clamping plates 44 allows them to be clamped onto the plate at the top of the concrete construction site to stably fix the connecting seat 30, making the monitoring of the mortar surface quicker and more convenient.

[0024] Please refer to Figures 1-6 The connecting seat 30 has a cavity 31 inside, and a through groove 32 is formed at the bottom of the cavity 31. The wire rope 50 extends into the cavity 31 from the through groove 32. The winding assembly 70 includes a connecting plate 71, a rotating shaft 72, and a knob 73. The two connecting plates 71 are respectively disposed on both sides of the cavity 31. The rotating shaft 72 is rotatably connected between the two connecting plates 71, and the top end of the wire rope 50 is wound around the outside of the rotating shaft 72. The knob 73 is located at the outer end of the rotating shaft 72 that extends out of the connecting seat 30. (The last sentence appears to be incomplete and possibly refers to a process involving concrete pouring.) When the density of the suspended ball 60 is lower than that of the concrete, it will move upward with the rise of the concrete, so that the steel wire rope 50 at the top of the suspended ball 60 is in a slack state. By rotating the knob 73, the shaft 72 between the two connecting plates 71 will rotate, so that the steel wire rope 50 wrapped around the outside of the shaft 72 will be pulled up onto the shaft 72, and the slack steel wire rope 50 will be tightened again. By observing the scale on the steel wire rope 50 when it is just taut, the position of the concrete stopping surface can be determined.

[0025] The functional principle of this application can be explained through the following methods:

[0026] In use, pull the two clamping plates 44 on one side of the fixed plate 20 outwards, allowing them to move to the top and bottom of the frame plate 10. Releasing the clamping plates 44 allows the spring force of the two springs 45 sleeved on the outer side of the guide rail 41 to move the two movable blocks 43 towards the fixed seat 42, thus moving the two clamping plates 44 towards the center position to fit tightly against the top and bottom of the frame plate 10, clamping the frame plate 10 between the two clamping plates 44. This fixes the fixed plate 20 to the side of the frame plate 10. Rotating the knob 73 on the front of the connecting seat 30 causes the knob 73 to drive the rotating shaft 72 to rotate between the two connecting plates 71. The rotation of the rotating shaft 72 removes the steel wire wound on the outside. Rope 50 is released from the through groove 32 at the bottom of cavity 31, allowing the suspended ball 60 at the bottom of the wire rope 50 to move down to the position where it contacts the concrete mortar surface before concrete is poured. As the concrete is poured, the height of the concrete mortar surface continuously increases. The suspended ball 60, which has a lower density than concrete, moves upward as the mortar surface rises, causing the taut wire rope 50 to loosen. When it is necessary to measure the height of the mortar surface, the knob 73 is rotated, causing the knob 73 to drive the rotating shaft 72 to rotate and retract the wire rope 50 wound on the outside. When the wire rope 50 is just taut, the scale corresponding to the scale line on the wire rope 50 can be observed to quickly determine the height of the mortar surface. The height of the concrete mortar surface can be continuously monitored.
