Description

Technical Field

[0001] This application relates to the field of water conservancy and hydropower engineering technology, and in particular to a simple measuring tool for precast segment steel reinforcement cages. Background Technology

[0002] Currently, the quality requirements for the fabrication of the reinforcing steel cage in precast tunnel segments are gradually increasing. The fabrication accuracy of the reinforcing steel cage significantly affects the difficulty of the precast tunnel segment production process, the thickness of the protective layer after product molding, and the compressive strength of the product. To ensure the fabrication accuracy of the reinforcing steel cage, quality inspectors must measure the reinforcing steel cage batch by batch to determine its qualification. The main contents include measuring the length of the reinforcing steel bars, the overall bending range of the reinforcing steel cage, and the spacing of the reinforcing steel bars, mainly using a measuring tape. However, due to the large number of measurement points and the different data at each point, the measurement process is often time-consuming and requires a high level of technical skill from the measurement personnel.

[0003] To effectively improve the efficiency of steel reinforcement cage measurement, it is necessary to invent a simple measuring tool for use during measurement, which can reduce measurement time, improve measurement efficiency, and save labor costs. Utility Model Content

[0015] Embodiments of this application will now be described in more detail with reference to the accompanying drawings. While embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art.

[0016] It should be understood that although the terms "first," "second," "third," etc., may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0017] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0018] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0019] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0020] Figure 1 This is a schematic diagram of the structure of a simple measuring tool for the steel reinforcement cage of precast tunnel segments, as shown in the embodiments of this application.

[0021] See Figure 1 1. A simple measuring tool for a precast tunnel segment reinforcing steel skeleton 4, comprising: a curved main ruler 1, a positioning clip 2, and a fixing nut 3. The tool is made of transparent polyvinyl chloride (PVC), which is lightweight and easy to use. The curved main ruler 1 has an arc-shaped groove, and the positioning clip 2 has a protrusion that matches the groove. The protrusion of the positioning clip 2 is embedded in the groove, and the positioning clip 2 is fixedly installed on the curved main ruler 1 corresponding to the reinforcing steel skeleton and locked by the fixing nut 3. The clip can be freely installed and removed from the main ruler. Figure 2 As shown, since the spacing of the reinforcing bars has an allowable error of ±5 mm, an error scale is set on the point clip 2, and the error of the reinforcing bar cage is ±5 mm.

[0022] In use, the dimensions of the curved main ruler 1 are determined based on the bending radius of the rebar cage. Then, the point clamps 2 are set according to the rebar spacing requirements for measurement. The overall bending amplitude of the rebar cage is determined based on the measurement of the curved main ruler, and the rebar spacing is measured by comparing it with the point clamps 2. Multiple data points of the rebar cage 4 can be measured and determined simultaneously. If the overall bending amplitude of the rebar cage exceeds the measurement error value or the rebar cage spacing exceeds the error, it is considered unqualified. The cage spacing can be easily determined by observing whether the cage and the point clamps correspond. If any cage misaligns with the point clamps 2 beyond the error scale of the point clamps 2, it is unqualified. This simple measuring tool can be installed indoors, and quality inspectors can use it directly at the construction site to simultaneously measure and determine the overall bending amplitude of the rebar cage and the rebar spacing.
