Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to an axial force measuring device for RC beam-cutting beams.

"Conventional technology" Conventionally, when measuring the axial force of RC beam beams, concrete strain gauges are buried inside the beam beams, or a flat jack is inserted in the appropriate position of the beam beams to measure the axial force. It is done by extracting information.

[Problems to be solved by the invention] However, all of them are disposable and expensive, and additionally have accessory equipment such as an oscillograph and a hydraulic device, which makes measurement difficult.

Further, in the former case, there is an inconvenience because it is impossible to collect the data, and it is not possible to confirm the situation. In the latter case, the stability of mounting is lacking, so that the place of use is extremely limited.

The present invention is intended to solve such conventional problems.

"Means for Solving the Problem" The present invention comprises an apparatus main body 1 and a material axis restricting member 2 which are interposed in the material axial direction at an intermediate portion of the RC sill beams B. A total of 11 and the jack 12 are connected in the axial direction so that both ends are brought into contact with both of the interrupted end faces B ₁₁ , B ₂₁ of the RC sill beam B. The main body 1 is detachably mounted so that both end portions 21 and ₂₂ are mechanically linked to both interrupted end peripheral surfaces B ₁₂ and B ₂₂ of the RC sill beam B.

"Operation" Since it has the above configuration, when using it, first,
The device main body 1 is intervened in the interrupted portion of the RC cut beam B ... in the axial direction of the material, and the jack 12 is actuated to press both ends to both interrupted end faces B ₁₁ and B ₂₁ of the cut beam. Next, the material axis regulating member 2 is mounted, and both end portions 21 and 22 of the material axis regulating member 2 are attached to both interruption end peripheral surfaces B of the beam.
₁₂ and B ₂₂ are mechanically linked to stabilize the axial direction of the beam.

After mounting in this way, the axial force meter 11 in the device main body 1
Axial force is measured by visually recognizing the display of.

When it is no longer needed, remove it in reverse order and use it again.

[Examples] The drawings show examples of the present invention.

In the drawings, A is an axial force measuring device according to the present invention, and B is an RC beam having the axial force measuring device mounted thereon.

The axial force measuring device A comprises a device main body 1 which is interposed in the material axial direction in the intermediate portion of the RC sill beams B ..., and a steel material shaft regulating member 2 which is arranged outside the device main body.

In the device body 1, the base end of the axial force meter 11 is integrally connected to the base end of the hydraulic jack 12 so as to be continuous in one axis direction, and the tip end of the axial force meter 11 and the end end of the hydraulic jack 12 are RC sill beams. It is arranged so as to be in contact with both interrupted end faces B ₁₁ and B ₂₁ of B.

The material axis regulating member 2 is composed of left and right symmetrical frame bodies 2a and 2b, and both frame bodies are two angle members each having an appropriate length.
23, 23 are joined and integrated by a joint metal 24, and the ends of the joint metal 24, which are protruded inward, are further bent upward or downward to form connection end portions 241, and these connection ends are formed. A proper number of through holes 242 ...
The left and right frame bodies 2a.2b are abutted at their connecting end portions 241, and are connected by bolts and nuts 25 through through holes 242.

Further, in order to mount the material shaft regulating member 2 on the RC cut beam B ..., an appropriate number of stud bolts 26 ... Are planted on both side surfaces of one end face B ₁₂ of the cut beam. Corresponding to the stud bolts, a proper number of through holes 211 are bored on both sides of the one end 21 of the material axis regulating member 2, these through holes 211 are fitted into the stud bolts 26 and the nuts 27 are screwed. The material axis regulating member 2 is detachably fixed to one of the interrupted end peripheral surfaces B ₁₂ of the cut beam by fitting and tightening, and further, at the other interrupted end peripheral surface B ₂₂ of the cut beam, Teflon sheets 28 are attached to the respective corner portions, and the other end portion 22 of the material axis regulating member 2 is slidably fitted through the Teflon sheets.

As shown in FIG. 3 and FIG. 4, the axial force measuring device A having the above-mentioned structure is provided with the required number of RC sill beams B ...
Provide for measurement.

[Advantage of the Invention] According to the present invention, the thrust can be directly read, the measurement can be performed easily and accurately, the device can be repeatedly used, and no auxiliary equipment is required, which is very economical.

Further, it is easy to attach and remove, has good workability, has high stability of attachment, and is excellent in safety.
