Description
Technical Field
The invention relates to a nondestructive quantitative detection device for a grouting sleeve for connecting reinforcing steel bars.
Background
At present, whether grouting materials in a grouting sleeve reach a set position is judged by observing whether grouting materials flow out through a grout overflow hole in the construction process; and if the grouting material overflows, the requirement is considered to be met, otherwise, the requirement is not met.
The grouting material of the grout outlet overflows, and the grouting material can only be proved to meet the requirements at that time. However, the grouting material is a flowable liquid before solidification, and whether the grouting material reflows before solidification cannot be determined; therefore, the existing judging method has the problems that the representation meets the requirement and whether the representation meets the requirement or not can not be defined. Detection cannot be performed at a later stage.

Detailed Description
The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
For ease of description, spatially relative terms, such as "upper," "lower," "left," "right," and the like, may be used herein to describe one element or feature's relationship to another element or feature as illustrated in the figures. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both an upper and a lower orientation. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
As shown in fig. 1 to 4, first, the principle of the present application is explained as follows: because there is a certain distance between the lower edge of the grout outlet 4 of the grouting sleeve for the reinforcing steel bar and the upper edge of the inner cavity of the grouting sleeve for the reinforcing steel bar, after the grout outlet 4 is blocked, a closed cavity 5 is formed at the part, and subsequent grouting material 7 cannot continuously enter, so that a permanent cavity is formed finally. If the grouting material overflows from the grout overflow hole 4, blocking, wherein the grouting material does not flow back after blocking, the grouting material 7 is poured in place, and the volume of the cavity 5 is assumed to be V0; if the grouting material 7 is blocked when overflowing from the grout overflow hole 4, the grouting material 7 reflows after blocking, or the grouting material 7 blocks the grout overflow hole when not overflowing from the grout overflow hole 4, at the moment, the grouting material 7 is not poured in place, and at the moment, the volume of the cavity 5 is assumed to be VC. When the volume value | VC-V0 | of the cavity in the grouting sleeve for connecting the steel bars is not less than Δ V, the pouring height 6 of the grouting material reaches the set position, and the pouring of the grouting material 7 meets the requirement; when the volume value VC-V0 of the cavity in the grouting sleeve for connecting the steel bars is larger than delta V, the pouring height 6 of the grouting material 7 does not reach the set position, or the pouring of the grouting material 7 does not meet the requirement.
The application provides a nondestructive quantitative detection device for a grouting sleeve for connecting reinforcing steel bars, which comprises an input liquid volume measuring instrument (not shown in the figure), an input pipeline 1, an output pipeline 2 and an output liquid volume measuring instrument 3; the input pipeline 1 and the output pipeline 2 are arranged at the top of the cavity in the detected sleeve; the input liquid volume measuring instrument is used for measuring the volume of the input liquid; the output liquid volume metering instrument 3 is connected with an outlet of the output pipeline 2, and the volume of the output liquid is metered after the flow of the outlet of the output pipeline 2 is stable; and (4) obtaining the volume of the liquid retained in the grouting sleeve by subtracting the volume of the input liquid from the volume of the output liquid.
Preferably, the bottom ends of the input pipeline 1 and the output pipeline 2 extending into the inner part of the detected sleeve keep a set distance; the part of the input pipeline 1 extending into the detected sleeve is more than the part of the output pipeline 2 extending into the detected sleeve; the pipeline ports are prevented from being too close to each other, and input detection liquid is directly flowed out of the output pipeline under the drive of air flow, so that detection distortion is caused. The bottom end of the part of the input pipeline 1 extending into the detected sleeve is higher than the upper edge of the detected sleeve by a set distance; so as to avoid the grouting material to submerge the input pipeline, cause pipeline blockage, and follow-up unable detection.
The detection device of the application has the following use process: when measuring the cavity volume in the grout sleeve for the reinforcing bar, will measure liquid input cavity 5 in the grout sleeve for the reinforcing bar through input pipeline 1, the gaseous of cavity 5 is discharged through output pipeline 2, after the stable outflow of measurement liquid in output pipeline 2, stops measuring the input of liquid, notes down the volume VA of measuring liquid through input pipeline 1 input this moment, the measurement liquid volume VB of flowing out through output pipeline 2. Subtracting the volume values of the two measurement liquids to obtain the volume VC of the measurement liquid retained in the grouting sleeve for the steel bar, namely: VA-VB = VC; and judging whether the pouring height 6 of the grouting material 7 reaches the standard or not by comparing the size of the | VC-V0 | with the size of the Δ V.
The above description is only for the purpose of illustrating the present invention, and it should be understood that the present invention is not limited to the above embodiments, and various modifications conforming to the spirit of the present invention are within the scope of the present invention.
