Description

Technical Field

[0001] The utility model relates to the field of building measurement, in particular to a building pile foundation compressive bearing capacity measurement bracket. Background Art

[0002] When measuring the compressive bearing capacity of the pile foundation, a dial indicator is needed to measure the sinking amount of the pile foundation under pressure; by analyzing the sinking amount of the pile foundation, the compressive bearing capacity of the pile foundation can be measured. The measuring bracket includes a reference beam and a reference pile. One end of the reference beam is fixed to the reference column, and the other end of the reference beam should be supported on the reference column. In the related technology, the reference column is composed of a bearing plate and four support rods. The four support rods are parallel to each other. The bearing plate is fixed between the four support rods and perpendicular to the support rods. The support rods are inserted at the bottom of the pit. The reference beam is installed on the side of the bearing plate away from the ground, and the micrometer is installed on the reference beam, so as to achieve accurate detection of the sinking amount of the pile foundation.

[0003] In the existing pile foundation compressive bearing capacity support, when the support rod is inserted into the bottom of the pit, the soil at the bottom of the pit is loose, resulting in insufficient stability of the support rod, which is easily affected by the external environment and shakes, causing shaking during the measurement of the micrometer, affecting the detection accuracy. At the same time, the reference beam needs to be used repeatedly, and holes need to be drilled on the reference beam to connect the micrometer with bolts. The fixed-point installation of the micrometer is inefficient and inconvenient to adjust. Utility Model Content

[0024] By providing a reference beam 3 outside the support rod 2, after the support rod 2 is inserted into the soil, the reference beam 3 is moved down so that the reference beam 3 is also inserted into the soil and is erected above the soil. The reference beam 3 is located on the outside of the support rod 2 and inserted into the soil to cooperate with the reference beam 3 to expand the supporting surface between the support rod 2 and the ground for stable support, thereby improving the stability of the support rod 2 to prevent it from shaking and affecting the measurement.

[0025] like Figure 3As shown, the stabilizing component 4 includes a connecting sleeve 41, which is movably sleeved on the outside of the support rod 2, and the inner side of the adjusting slot 31 is movably clamped with a fastening gasket 42, and the outer side of the connecting sleeve 41 is threadedly connected to a locking bolt 43 located on the outside of the fastening gasket 42, and a connecting plate 44 is fixedly connected to the lower part of the outside of the connecting sleeve 41, and a support frame 45 is fixedly connected to the outer side of the connecting plate 44, and a stabilizing plate 46 is fixedly connected to the bottom of the support frame 45, and a fixing groove 47 is opened inside the stabilizing plate 46, and an embedded plate 48 is fixedly connected to the inside of the fixing groove 47.

[0027] like Figure 4 and Figure 5 As shown, the fixing assembly 5 includes a sliding seat 51, and locking bolts 52 are threadedly connected to the front and rear sides of the sliding seat 51. An anti-skid gasket 53 is movably clamped on the inner side of the sliding seat 51, and the position of the anti-skid gasket 53 corresponds to that of the locking bolts 52. A connecting hole 54 is opened at the bottom of the sliding seat 51.

[0028] The sliding seat 51 is moved along the adjusting groove 31 to the installation position of the micrometer, and then the locking bolt 52 is rotated to make it move inward along the sliding seat 51 to press the anti-slip gasket 53 so that the anti-slip gasket 53 is pressed against the inner wall of the adjusting groove 31 for locking and fixing. The fixing rod 6 is screwed along the connecting hole 54 at the bottom of the sliding seat 51, and the micrometer is clamped and installed on the fixing rod 6, so that it is convenient to install the micrometer and adjust the position at the same time.

[0029] like Figure 3 As shown, three embedded plates 48 are provided, and the three embedded plates 48 are arranged in a triangle at the bottom of the stabilizing plate 46 .

[0031] like Figure 3As shown, the insert plate 48 is configured to transition downward and become thinner.

[0032] The embedding plate 48 transitions downward and becomes thinner so as to facilitate insertion into the soil.

[0034] By setting the rubber gasket, the fastening gasket 42 is pressed against the outside of the support rod 2 by the locking bolt 43 to be fixed.

[0040] like Figures 1 to 5 As shown, by sleeve-arranging the connection sleeve 41 on the outside of the support rod 2, and by connecting the support rod 2 with the bearing plate 1, inserting it into the soil, and then sliding the connection sleeve 41 downward along the support rod 2, the connection sleeve 41 drives the connection plate 44 and the support frame 45 to move downward, thereby driving the stabilizing plate 46 to contact the ground. At the same time, by applying force to the support frame 45, the embedded plate 48 in the fixing groove 47 is inserted into the soil and located on the outside of the support rod 2, and at the same time, the stabilizing plate 46 is compacted above the soil, and by rotating the locking bolt 43, it moves into the connection sleeve 41 to press against the fixing pad.
