Description

Technical Field

[0001] The utility model relates to the technical field of self-compacting concrete measurement, in particular to an expansion base plate device with the function of measuring the compaction and expansibility of self-compacting concrete. Background Art

[0002] Concrete is an artificial stone made of cementitious materials, granular aggregates also called aggregates, water, and admixtures and additives added when necessary in a certain proportion, which are evenly mixed, compacted into shape, and cured and hardened. The expansion of self-compacting concrete refers to its ability to flow and fill naturally inside the concrete. The higher the expansion, the better the self-compacting performance of the concrete, which can effectively prevent air pores inside the concrete. At the same time, the expansion can also affect the slump, fluidity and plasticity of the concrete. In the process of measuring self-compacting concrete, an expansion base plate device is required.

[0003] For example, the utility model with application number 202122744171.3 discloses a detection device for concrete. The utility model uses the longitudinal scale and concentric circle scale set on the substrate to make the measurement of concrete expansion simple and easy, that is, the concrete expansion result is highly accurate. However, after measurement, this type of device needs to use a trowel to shovel away the concrete on the substrate, which is time-consuming to clean up and may also scratch the scale, affecting subsequent normal observation.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an extended base plate device with the function of measuring the compaction and expansibility of self-compacting concrete is provided. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an expansion base plate device with the function of measuring the compaction and expansibility of self-compacting concrete, comprising a base plate and a positioning assembly, a scale is arranged on the top of the base plate, and the positioning assembly is arranged on both sides of the base plate, the positioning assembly comprises a rotating plate, a positioning plate, a rubber strip, a limit frame, a latch, a retaining ring, a positioning spring and a positioning hole, a positioning plate is fixed at the upper end of the rotating plate, and a rubber strip is arranged at the bottom of the positioning plate, a limit frame is fixed on one side of the middle part of the positioning plate, and a latch is slidably connected inside the limit frame, a retaining ring is fixed on the outer side of the middle part of the latch, and a positioning spring is arranged on one side of the retaining ring, and positioning holes are opened on both sides of the base plate.

[0007] Furthermore, the latch is slidably connected to the base plate through the positioning hole, and the length of the base plate is substantially consistent with the length of the positioning plate.

[0008] Furthermore, side plates are fixed to both side ends of the substrate, one end of the side plate is rotatably connected to a reeling roller, and the middle part of the side plate is rotatably connected to a limiting roller.

[0009] Furthermore, a cutting assembly is provided at the upper end of the side panel, and the cutting assembly includes a cutting board, a support frame and a pressure rod. The cutting board is fixed between the side panels, and a support frame is fixed on the top of the side panel, and the pressure rod is slidably connected to the inside of the support frame.

[0010] Furthermore, the cutting assembly also includes a support spring, a lifting plate and a cutter. The support springs are sleeved on the outer sides of both ends of the pressure rod, and the lifting plate is fixed to the bottom of the pressure rod, and the cutter is placed in the center of the bottom of the lifting plate.

[0011] Furthermore, the base plate is rotatably connected to the rotating plate, and the width of the base plate is equal to the length of the cutter.

[0012] Furthermore, the cutting assembly also includes a spring seat and a pressure plate. The two ends of the bottom of the lifting plate are provided with spring seats, and the bottom of the spring seat is connected to the pressure plate.

[0013] Furthermore, the spring seats are equidistantly distributed about the bottom of the lifting plate, and the lifting plate is slidably connected to the side plate.

[0014] The utility model provides an expansion base plate device with the function of measuring the compaction and expansibility of self-compacting concrete, which has the following beneficial effects:

[0015] 1. The utility model can cover the transparent plastic film on the base plate before use through the setting of the positioning component, and then rotate the rotating plate so that the positioning plate is located above the plastic film. At this time, the positioning spring will push the retaining ring so that the pin is inserted into the positioning hole, and the position of the positioning plate can be quickly positioned through the limit frame, so that the deformation performance of the rubber strip is used to press the plastic film. Therefore, when measuring the compaction and expansion performance of the self-compacting concrete, the scale on the base plate can also be observed through the transparent plastic film. After the measurement, the pin is pulled to slide it out of the positioning hole, and the positioning plates on both sides can be opened, so that it is also very convenient to take out the plastic film. Compared with the existing need to use a trowel to scrape the self-compacting concrete into the collection bucket for collection many times, the present application only needs to lift the plastic film to quickly pour the self-compacting concrete into the collection bucket, thereby saving time and effort when cleaning, and will not damage the scale on the base plate;

[0016] 2. The utility model is provided with a cutting assembly. When it is necessary to cut the plastic film, the lifting plate can be driven downward by simply pressing the pressure rod. At this time, since the bottom of the pressure plate is lower than the bottom of the cutter, the pressure plate will first contact the plastic film, thereby pressing and positioning the plastic film above the cutting plate under the squeezing of the spring seat, so that the subsequent cutter can contact the tensioned plastic film, which is beneficial to improving the cutting effect. After letting go, the supporting spring will push the pressure rod, thereby driving the lifting plate to move up, making it convenient for personnel to take the plastic film below. At the same time, the bottom of the pressure plate is lower than the cutter, which can also prevent personnel from accidentally touching the cutter, thereby improving safety during use.

After measurement, the latch 605 is pulled to slide it out of the positioning hole 608, and the positioning plates 602 on both sides can be opened, which is also very convenient when taking out the plastic film.

[0023] like Figure 1 and Figure 3As shown, a cutting assembly 7 is provided at the upper end of the side plate 3, and the cutting assembly 7 includes a cutting plate 701, a support frame 702 and a pressure rod 703. The cutting plate 701 is fixed between the side plates 3, and the support frame 702 is fixed on the top of the side plate 3, and the pressure rod 703 is slidably connected inside the support frame 702.

The position of the positioning plate 602 can be quickly positioned by the limit frame 604, so that the deformation performance of the rubber strip 603 is used to press the plastic film. Then, according to the conventional steps for measuring the expansibility of the self-compacting concrete, after the self-compacting concrete is poured at the center of the substrate 1, the self-compacting concrete will expand to the surrounding areas. After the expansion stops, the scale 2 on the substrate 1 can also be observed through the transparent plastic film, which is convenient for recording the compaction and expansion performance of the self-compacting concrete. Then, after measuring, just press down the pressure rod 703 to drive the lifting plate 705 to move down.
