Description
Technical field
The utility model relates to a kind of right cylinder test specimen diameter measurement aid.
Background technology
The right cylinder test specimen is very common a kind of test specimen in building trade, highway industry detection technique, as concrete core sample, elastic modulus test specimen etc., but on its diameter measurement, lacks suitable survey instrument, meets the requirement of standard operation.
According to CECS03:2007 factor about core-drilling test concrete strength technical regulation, 6.0.4 bar, the concrete core sample mean diameter is measured on orthogonal two positions, core test specimen middle part with vernier caliper, gets the diameter of the arithmetic mean of measurement as the core test specimen, is accurate to 0.5mm;
According to JTG E30-2005, T0551-2005 cement concrete test specimen is made and hardened cement concrete on-site sampling method 6.3.2: centre and two 1/4 places at the core height determine the mean diameter dm of core by two vertical direction measurement three logarithm value, be accurate to 1.0mm.
And the conventional vernier caliper of commonly using is not in the market accomplished intermediate altitude place measurement diameter due to the long restriction of outside diameter measuring pawl.Take the concrete core sample test as example, common core diameter is generally 150mm ± 10mm, and in the market the circulation its outside diameter measuring pawl size of conventional vernier caliper in Table 1,
| Measurement range/mm | 0-150 | 0-200 | 0-300 | 0-500 | 0-1000 | 0-1500 |
| Outside diameter measuring pawl length/mm | 40 | 50 | 60 | 80 | 100 | 150 |
Table 1
As from the foregoing, when core diameter to be measured was larger, the long restriction of vernier caliper pawl made the diameter of measuring less than the core middle part.If adopt the wide range vernier caliper, as 0-1500mm, its market circulation is all more than thousand yuan, and not portable, takes up an area larger.In addition,, as adopting straight steel ruler, also can only measure the diameter of top and bottom, not meet code requirement.
Summary of the invention
The purpose of this utility model provides a kind of right cylinder test specimen diameter measurement aid, is applicable to coordinate various survey instruments at the external diameter of measuring large cylinder, calculates simple and easy, simple to operate, low to the condition of work requirement, be beneficial to engineering and use, meet engineering discipline and measure needs.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of right cylinder test specimen diameter measurement aid, comprise the slip armed lever, one end of slip armed lever vertically is connected with fixed clamping arm, also be provided with the slip clamp gripping arm that is slidably connected with it on the slip armed lever, the slip clamp gripping arm is connected with the slip armed lever is vertical.
One end of described slip clamp gripping arm is provided with and its radially vertical through hole, and the slip armed lever penetrates in through hole to coordinate to form and is slidably connected, and at both connecting portions, can lock by fastening bolt.
Described slip clamp gripping arm is for vertically shaft-like.
Described slip clamp gripping arm consists of at the vertical two ends that are connected to the 3rd body of rod respectively with the second bar bar first body of rod, and first body of rod and the second bar bar are distributed in the both sides of the 3rd body of rod.
The length of described fixed clamping arm and slip clamp gripping arm is greater than the diameter of test specimen to be measured.
The utility model carries out clamping by fixed clamping arm and slip clamp gripping arm with core to be measured, then with the distance between vernier caliper or straight steel ruler equal length survey instrument measurement fixed clamping arm and slip clamp gripping arm, then calculate the diameter of core to be measured fixed position, meet measurement demand, the core diameter that records by the method, degree of accuracy is high, the coincidence measurement requirement.And the utility model is simple in structure, and is easy to use, low to the condition of work requirement, is beneficial to engineering and uses, and meets engineering discipline and measures needs.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of embodiment 1.
Fig. 2 is the structural representation of embodiment 2.
Fig. 3 is use constitutional diagram of the present utility model.
Embodiment
Embodiment 1: as shown in Figure 1, this device comprises slip armed lever 1, and an end of slip armed lever 1 vertically is connected with fixed clamping arm 2, also is provided with the slip clamp gripping arm 3 that is slidably connected with it on slip armed lever 1, and slip clamp gripping arm 3 is connected with slip armed lever 1 is vertical.One end of described slip clamp gripping arm 3 is provided with and its radially vertical through hole, and slip armed lever 1 penetrates in through hole to coordinate to form and is slidably connected, and at both connecting portions, can lock by fastening bolt.The length of described fixed clamping arm and slip clamp gripping arm is greater than the diameter of test specimen to be measured.
Embodiment 2: as shown in Figure 2, the difference of this device and embodiment 1 is, described slip clamp gripping arm 3 consists of at the vertical two ends that are connected to the 3rd body of rod 33 respectively with the second bar bar 32 first body of rod 31, first body of rod 31 and the second bar bar 32 are distributed in the both sides of the 3rd body of rod 33, and the second bar bar 32 is connected with slip armed lever 1 is vertical.This design can be measured the larger core of diameter, due to the use of this aided measurement device, the range of survey instrument is required and can greatly reduce.
During use, as shown in Figure 3, by fixed clamping arm and slip clamp gripping arm with the detected part clamping of core 4 to be measured, make two clamping limbs all vertical tangent with core to be measured, then measure fixed clamping arm and the free-ended distances of slip clamp gripping arm with survey instrument 5, the shared size of width that deducts clamping limb by calculating can obtain the diameter of core.
