Description

  The present invention works on a roof bolt testing machine for measuring whether or not the existing hook bolt has a strength that can withstand reuse in order to leave the existing slate roof in the roof repair work. The present invention relates to a mounting apparatus for a roof bolt testing machine that can be stably installed on a roof such as an existing slate so that an operator can operate safely, and an installation method thereof.

  Refurbish existing slate roofs and install new roofs on existing slate roofs, and re-install existing hook bolts for fixing slate roof plates and slate roof tiles to structural materials such as main buildings. In some cases, this existing hook bolt may be equipped with a support fitting or the like for forming a roof plate material for a new roof.

  Alternatively, it may be constructed as a green roof on the existing slate roof, in addition to the new roof. Even in such a case, the support fitting may be mounted on a roof such as an existing slate using an existing hook bolt. However, existing hook bolts for roofs such as existing slate may be corroded or deteriorated considerably due to environmental conditions such as long-term wind, rain, snow or changes in temperature such as weather and climate. May exist.

Existing hook bolts that are extremely deteriorated are unsuitable for mounting support brackets, etc., or even if they are not extremely deteriorated, they have passed the service life and can be reused. Can be dangerous. However, it is difficult to determine the degree of such deteriorated existing hook bolts by visual observation. For this purpose, a measuring tool such as a tensile tester is used to measure and inspect the strength of the existing hook bolt and determine whether or not the reuse is possible.

By providing the anti-slip material 44 on the base member 41 and the movable member 42, it is possible to further ensure the safety of workers.

  Next, a method for installing the mounting device on the roof A such as an existing slate will be described. First, the fixing member 1 is arranged on the existing fixing device 105 located on the front side (under water or eaves side) of any existing fixing device 105 to be subjected to the tensile strength test (see FIG. 10A). ]. In this case, the fixing member 1 is temporarily fixed using the bolt shaft portions 105a of the plurality of existing fixing tools 105 mounted at predetermined intervals along the longitudinal direction of the existing structural member 104.

  Further, in this temporary fixing, the existing nut 105c and the existing washer 105d that are screwed to the bolt shaft portion 105a are left in the existing through hole for fixing formed in the fixing member 1 without being removed.

  As shown in FIGS. 1 and 5, the tensile strength tester 7 includes a tester 71 and a display 72. Here, when the tensile strength tester 7 is used for a tensile strength test of the bolt shaft portion 105a of the existing fixture 105 on the roof A such as an existing slate, the tensile strength tester 7 becomes a roof bolt tester. The testing machine 71 includes a coupling 71a, a screw shaft 71b, and an operation handle 71c. Further, the display 72 displays the result of the tensile strength test of any existing fixture 105 performed by the testing machine 71. The tensile strength tester 7 is provided with a plurality of leg columns 71d, 71d,.

  Then, a plate-like pedestal 73 is disposed on the reinforcing table 3, and the coupling 71a of the testing machine 71 is screwed into the bolt shaft portion 105a of the arbitrary existing fixture 105 (see FIG. 5). By rotating the operation handle 71c, the screw shaft 71b is rotated, and the bolt shaft portion 105a of the existing fixture 105 is pulled in the axial direction together with the coupling 71a, and a tensile strength test is performed. It is displayed on the display 72.

  In this way, the tensile strength tester 7 for determining whether or not the existing fixture 105 on the roof A such as the existing slate can be reused is installed on the existing roof A such as the slate in an extremely stable state. Therefore, the inspection and measurement work of the worker by the tensile strength tester 7 can be performed extremely safely. Furthermore, since the work can be performed safely, the measurement accuracy can be increased as a result.
