[0038] Reference Appendix Figures 1-6This embodiment provides a multifunctional measuring instrument for the butt joint of precast square piles. It is used to measure the verticality of the upper square pile 10 or the misalignment distance between the two square piles after the upper square pile 10 and the lower square pile 11 are butt jointed and before welding, or to measure the weld height and fullness after the upper square pile 10 and the lower square pile 11 are butt jointed and welded. This multifunctional measuring instrument specifically includes: a folding ruler 1, a first abutment plate 2, a second abutment plate 4, a weld seam measuring block 3, and sliding rods 5. The folding ruler 1 is a mature product, and its integration with other structures in this instrument is mainly for ease of carrying and practicality. The model of the folding ruler 1 can be selected by those skilled in the art according to actual usage needs. The specific structure is not described in detail here, but in order to accurately illustrate the position and connection relationship of other structures in this instrument, based on the existing structure of the folding ruler 1, the side of the folding ruler 1 used to abut the object to be measured is designated as the abutment surface 1.1, while the side opposite to the abutment surface 1.1 is designated as the non-abutment surface 1.2. The bottom surface of the first abutment plate 2 is connected to the non-abutment surface 1.2 of the folding ruler 1, and the top surface is connected to the weld seam measuring block 3. Several sliding rods 5 are inserted through the weld seam measuring block 3 and can slide along the thickness direction of the first abutment plate 2. The second abutment is parallel to the plate surface of the first abutment plate 2, and its bottom end is connected to the weld seam measuring block 3, and it can move along the thickness direction of the first abutment plate 2 on the weld seam measuring block 3.

[0039] During the precast square pile docking construction, the lower square pile 11 is first driven into the pile hole, with the top of the lower square pile 11 extending a certain distance beyond the foundation. Then, the upper square pile 10 is hoisted above the lower square pile 11, and the folding straightedge 1 is unfolded. The measuring surface 1.1 of the folding straightedge 1 is used to abut against the side wall of the upper square pile 10 to check the verticality of the upper square pile 10. Then, the folding straightedge 1 is folded up, and the surface of the first abutment plate 2 is pressed against the side wall of the lower square pile 11. The second abutment plate 4 is slid until it presses against the side wall of the upper square pile 10. Based on the relative positional relationship between the first abutment plate 2 and the second abutment plate 4, the horizontal misalignment distance between the upper square pile 10 and the lower square pile 11 is calculated. When the verticality is qualified and the misalignment distance is within acceptable limits, the horizontal misalignment distance is considered. When the distance is within the tolerance range, welding work can be carried out on the upper section square pile 10 and the lower section square pile 11. After welding, one end of the sliding rod 5 is flush with the plate surface of the first abutment plate 2, and the plate surface of the first abutment plate 2 is pressed against the side wall of the lower section square pile 11. The position of the weld measuring block 3 and the weld 12 is aligned. Since the weld 12 protrudes from the side wall of the lower section square pile 11 in the horizontal direction, the weld 12 will push the sliding rod 5, causing the sliding rod 5 to slide along the thickness direction of the first abutment plate 2 and extend from the other end of the weld measuring block 3. The weld height can be calculated by observing the extension distance of the other end of the sliding rod 5. The fullness of the weld at each point along the precast square pile can be judged by evaluating the extension state of multiple sliding rods 5.

[0040] As mentioned above, since weld 13 protrudes horizontally from the side wall of the lower square pile 11, the thickness of weld measuring block 3 must be less than that of the first abutment plate 2 to avoid the first abutment plate 2 failing to abut the side wall of the lower square pile 11. Therefore, in this embodiment, weld measuring block 3 is specified to have a first side surface 3.1 and a second side surface 3.2, which correspond to the directions of the two side surfaces of the first abutment plate 2, respectively. However, at least one of them is concave relative to the surface of the first abutment plate 2. That is, the thickness of weld measuring block 3 is less than that of the first abutment plate 2, so that when the first abutment plate 2 abuts the side wall of the lower square pile 11, there is a gap or just abuts the weld 12 between the side surface of weld measuring block 3 near weld 12 (which can be the first side surface 3.1 or the second side surface 3.2).

[0041] To improve the convenience of measurement, the outer wall of the slide rod 5 is provided with a first scale 5.1, which is distributed along the axial direction of the slide rod 5. The weld height can be calculated directly by reading the first scale 5.1. In addition, limit blocks 6 are provided at both ends of the axial direction of the slide rod 5. The diameter of the through hole of the slide rod 5 on the weld measuring block 3 is smaller than the cross-sectional size of the limit block 6 to prevent the slide rod 5 from slipping off the weld measuring block 3.

[0042] To fully measure the fullness of the weld, it is preferable to set multiple rows and columns of sliding rods 5 on the weld measuring block 3. When the first abutment plate 2 abuts against one side wall of the lower square pile 11, the weld corresponding to that side wall fully squeezes these sliding rods 5. Based on whether the elongation of the other end of these sliding rods 5 is within the tolerance range of the weld height, the fullness of each point in this weld can be judged. If it is not qualified, it needs to be repaired by welding.

[0043] On the other hand, see the attached document. Figure 2 The weld seam measuring block 3 is provided with a sliding groove 7, the length direction of which is the same as the thickness direction of the first abutment plate 2. The second abutment plate 4 is provided with a slider 8. The slider 8 can slide in the sliding groove 7 or be fixed in the sliding groove 7 by the locking component 9. The locking component 9 can fix the relative position of the second abutment plate 4 and the weld seam measuring block 3, that is, fix the relative position of the second abutment plate 4 and the first abutment plate 2, so as to measure the degree of relative displacement between the second abutment plate 4 and the first abutment plate 2, and thus obtain the misalignment distance between the upper square pile 10 and the lower square pile 11.

[0044] Reference Appendix Figure 2The locking assembly 9 includes a locking block 9.1, a locking groove 9.2, and a sliding button 9.3. The locking block 9.1 is located inside the slider 8 and can move along the width of the sliding groove 7 to extend out of the slider 8. The locking groove 9.2 is located on the inner side wall of the sliding groove 7 and is used to lock and fix the locking block 9.1. The slider 8 has an elongated through hole 8.1, and the sliding button 9.3 passes through the elongated through hole 8.1 and connects to the locking block 9.1. By sliding the sliding button 9.3, the locking block 9.1 can be extended and retracted inside and outside the slider 8, realizing the locking or separation of the locking block 9.1 and the locking groove 9.2. When the two are separated, the slider 8 can move in the sliding groove 7, thereby allowing the second abutment plate 4 to move along the thickness direction of the first abutment plate 2.

[0045] Preferably, two sets of locking blocks 9.1 are arranged opposite each other. Each locking block 9.1 is connected to a sliding button 9.3. The near ends of the two sets of locking blocks 9.1 are connected by a spring 9.4, and the far ends are respectively engaged with the slots 9.2 on the two inner sidewalls of the slide groove 7. When the two sliding buttons 9.3 are brought closer together, the two locking blocks 9.1 move closer together and retract into the slider 8. At the same time, the spring 9.4 is compressed, and the second abutment plate 4 and the slider 8 can slide. After release, under the action of the spring 9.4, the two locking blocks 9.1 move away from each other, and the two sliding buttons 9.3 move away from each other, which can automatically realize the engagement of the locking blocks 9.1 with the slots 9.2. In implementation, the shape of the sliding button 9.3 can be configured according to specific needs, and is not specifically limited here.

[0046] To improve the convenience of measurement, a second scale 7.1 is provided at the top of the chute 7. The second scale 7.1 is distributed along the thickness direction of the first abutment plate 2. The relative displacement between the second abutment plate 4 and the first abutment plate 2 can be calculated directly by reading the second scale 7.1, thereby obtaining the misalignment distance between the upper square pile 10 and the lower square pile 11.

[0047] Furthermore, for faster measurement, the following configuration can be made: the first abutment plate 2 and the second abutment plate 4 have the same thickness. In this way, the misalignment distance between the upper square pile 10 and the lower square pile 11 can be obtained directly by reading the second scale 7.1, without the need for further calculation based on the thickness difference between the first abutment plate 2 and the second abutment plate 4, which can greatly increase the efficiency of measurement.

[0048] Compared with the prior art, the beneficial effects of this utility model include: this instrument integrates functions such as weld measurement, verticality measurement, and misalignment distance measurement of upper and lower piles, which can reduce the amount of measuring tools to carry during construction, is convenient to use and easy to operate.

[0050] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
