Description

Technical Field

[0001] This utility model relates to the field of measuring the misalignment of reinforcing bars in structural components within the steel structure manufacturing industry. Background Technology

[0002] The rib alignment measuring fixture is used to measure the misalignment of the ribs between a plate and another plate at a symmetrical position. It can measure the misalignment of the ribs between the two parts of the pipe body after the quay crane's ribs and gusset plates are assembled, as well as similar situations involving the rib alignment of other plate assemblies, completing the measurement of one point at a time. Observation of the current quay crane frame assembly process, specifically the rib alignment measurement method for the two parts of the pipe body separated by the gusset plate after the ribs and gusset plates are assembled, reveals the following drawbacks: First, it requires two people (one above and one below) to complete a single measurement operation. Second, it requires two people (one above and one below) to work together to complete a single measurement. Second, the operation involves numerous and cumbersome steps. Each measurement point requires six steps and six sets of data to complete a single measurement, resulting in significant cumulative errors. Third, the operator is working in a high, narrow area near an edge, which is unsafe. Fourth, this measurement method is labor-intensive, time-consuming, and prone to errors, affecting product quality. The operation is complex and poses safety hazards. Summary of the Invention

[0003] The purpose of this utility model is to address the aforementioned drawbacks of existing measurement methods by disclosing a strut-alignment measuring device, which includes: a ruler, a base, a limiter, and fasteners.

[0004] The ruler includes two standard rulers.

[0005] The base is a rectangular plate with a groove, an elongated through hole, and a circular through hole.

[0006] The fastener includes countersunk bolts, large-head bolts, nuts, and washers.

[0007] The limiter includes a structure with a "C"-shaped opening, and the structure includes a groove with a "┻"-shaped cross-section. The structure includes a threaded hole and a countersunk hole.

[0008] The limiter is embedded in the groove of the base, with the groove opening facing outward. It is connected to the base by fasteners and can move freely along the axial direction of the groove of the base. Tightening the fasteners restricts its movement.

[0009] The ruler, which is inserted into the "┻" shaped groove of the limiter, can move freely along the axial direction of the groove of the limiter, and the fastener is tightened to restrict its movement.

[0010] The technical effects achieved by this utility model are as follows:

[0011] 1. Avoid using a measuring tape; choose a ruler instead. It is less prone to deformation, provides intuitive readings, and offers high measurement accuracy.

[0012] 2. The tool integrates two rulers, making it easy to adjust, compact, and lightweight. It can be operated by a single person and is safe and reliable.

[0013] 3. With simple tooling, the misalignment value of the reinforcing bars at a single point can be measured in one go.

[0014] 4. The measurement range is adjustable, making it suitable for measuring components of various specifications and with a wide range of applications. Attached Figure Description

[0023] To better understand the above-mentioned technical solution of this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; or a mechanical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] like Figure 4 As shown, combined with Figures 1 to 7 As shown in the figure, as a specific embodiment of this utility model, a strut-alignment measuring fixture is disclosed, which can be used in the field of steel structure manufacturing. The strut-alignment measuring fixture is an assembly including a ruler, a base, a limiter and fasteners. The ruler can move and be fixed freely in two-dimensional space, that is, it realizes the function of measuring with two rulers at the same time.

[0026] The base 2 is made of a hard and resistant plate that is not easily deformed. One side has a rectangular groove 21 in the middle. The axis of the groove along its length is parallel to the axis of the base along its length. The cross-section of the groove is rectangular.

[0027] The limiter 3 is a "C"-shaped structure with a "┻"-shaped groove 31 in the middle and a threaded hole 33 at one end for installing the large-head bolt 7. The bottom of the "┻"-shaped groove 31 has a countersunk hole 32. The size of the limiter 3 is slightly smaller than the size of the rectangular space groove 21 of the base 2 so that the limiter 3 can be embedded in the rectangular space groove 21 and can slide freely along the axis of the rectangular space groove 21.

[0028] The axis of the "┻" shaped groove 31 of the limiter 3 is perpendicular to the axis of the rectangular space groove 21 of the base 2.

[0029] Two limiters 3 are embedded in the rectangular spatial groove 21 of the base 2. The countersunk hole 32 of one limiter 3 is aligned with the circular through hole 23 of the base 2. A countersunk bolt 4 is passed through both holes and secured to the base with a nut 6 and a washer 5. This limiter 3 is immovable. The countersunk hole 32 of the other limiter 3 is aligned with the oblong through hole 22 of the base 2. A countersunk bolt 4 is passed through both holes and secured to the base 2 with a nut 6 and a washer 5. This limiter 3 is movable. When movement is required, the nut 6 is loosened, allowing it to move freely along the axial direction within the rectangular spatial groove 21.

[0030] The width and thickness of the ruler 1 are slightly smaller than the spatial dimensions of the "┻" shaped groove 31 of the limiter 3, so that after the ruler 1 is inserted into the groove 31, it can move freely along the axial direction of the "┻" shaped groove 31.

[0031] Ruler 1: Two standard rulers of the same length.

[0032] This utility model is used as follows:

[0033] In steel structure fabrication and construction, when two plates are separated by another plate a and cannot be directly connected, these two plates need to meet the reinforcement design requirements. To verify and measure the misalignment difference of the reinforcement, this utility model is used. Loosen the nut 6 of the movable limiter 3 of this utility model, slide the limiter 3 to create a certain distance between the two limiters 3, and at this time, create a certain distance between the two rulers. This distance is approximately equal to the thickness of plate a. Loosen the large bolt 7, move the ruler 1 to the estimated length, which is approximately equal to the distance from the plate to the edge of plate a. At this time, the state of this utility model resembles an open pair of scissors. Insert plate a between the two rulers 1, with the edge of plate a pressed against the edge of the base 2. Move the limiter 3 so that the two rulers 1 are pressed against the surface of plate a, and tighten the nut 6 so that the limiter 3 no longer moves. Then move the two rulers 1 so that the ends of the rulers at their zero points are against the plates, and tighten the large-head bolts 7 so that the large-head bolts 7 are against the rulers 1 to prevent the rulers from moving. At this time, a certain scale on the two rulers is aligned with the edge of the base 2. Observe the scale values ​​of the two rulers at the aligned point. The difference between them is the misalignment value of the ribs of the two plates. In this way, the misalignment measurement of a point on the two plates is completed.
