Description

  The present invention is used for construction inspection of building work, and after assembling the beam formwork, a beam sleeve that is installed together with the beam rebar is the object to be measured, and a concrete floor level (hereinafter referred to as a virtual slab thickness) before concrete placement The present invention relates to a beam sleeve height inspection apparatus for actually inspecting a mounting height which is minus-displayed as a distance from the construction standard FL.) To the axis of the beam sleeve.

  In the construction drawing of the building work, the mounting height of the beam sleeve is negatively displayed as the distance from the construction standard FL that assumes the slab thickness to the axis of the beam sleeve. The beam sleeve is usually installed and installed together with the beam reinforcement after the beam formwork is assembled. Conventionally, in the construction inspection, the height from the beam formwork installation surface is measured using a scale such as a measure or a metal scale, and the slab thickness and the radius of the beam sleeve are added to collate with the numerical values in the construction drawing. It was.

Regarding the installation of the beam sleeve, there have been proposals for fixing methods and positioning methods (including mounting jigs). (For example, see Patent Documents 1, 2, and 3.)

  However, all of the above conventional techniques relate to construction techniques and do not solve the conventional problems in construction inspection.

  A conventional problem in construction inspection is the addition of the actual measured height from the beam formwork installation surface to the pipe wall for each beam sleeve, the slab thickness, and the radius of the beam sleeve (1/2 of the sleeve outer diameter). Then, it took time and effort to collate with the numerical value of the construction drawing. Here, there is a demand for a measuring means that can immediately collate with the numerical value of the construction drawing by one actual measurement (reading value) by direct reading. As specific measuring means, a slide gauge that handles a main scale and a vernier scale, as seen in calipers, height gauges, depth gauges, and the like, is considered.

  In addition, since the inspection is performed after the reinforcing bars of the beam reinforcement and the beam sleeve are installed, these may become obstacles and the scale cannot be brought into contact with the pipe wall vertically, making accurate measurement difficult. there were. Here, an instrumental means that can correctly access the object to be measured by a simple operation is required.
