Description

Technical Field

[0001] The present application relates to the field of measuring rulers, and in particular to a measuring ruler for civil engineering. Background Art

[0002] Civil engineering is a general term for the construction of various land engineering facilities, which refers to the materials and equipment used, the technical activities such as survey, design, construction, maintenance, and repair, as well as the objects of engineering construction;

[0003] The measuring ruler is an important tool used in civil engineering. As a kind of measuring ruler, the tape measure plays a vital role in civil engineering. It is one of the indispensable basic measuring tools on the construction site and is widely used in various measurement and layout tasks. In the early stages of civil engineering, the tape measure can be used to measure and mark the foundation position, contour line and height difference before and after the ground leveling operation of the building to ensure the accurate alignment of the foundation construction. The tape measure is also used to determine the vertical and horizontal positions of structures such as walls and columns to ensure that their relative positions are accurate. It is also used to measure dimensions such as wall thickness and column diameter.

[0004] The end of the existing measuring tape is often provided with a right-angle block. In the process of building walls, installing door and window frames or laying floors, the right-angle block can be used to detect the verticality and flatness of walls, columns or components, and help workers determine whether the construction meets the requirements of specifications. However, the right-angle block of the existing measuring tape is often fixed at the end of the measuring ruler. When it is necessary to determine the vertical position of structures such as walls and columns, the bottom of the right-angle block is in contact with the vertical surface, so that there is a certain distance between the measuring tape surface and the vertical surface. In the process of pulling the measuring tape upward, the measuring tape surface will be tilted or even deviated due to the gap, which will cause the accuracy of the measured data to deviate. In order to solve the above problems, a measuring ruler for civil engineering is proposed.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0009] Preferably, a slide block 2 is fixed to one end of the measuring ruler, and a slide groove 3 for sliding of the slide block 2 is provided on the right-angle stopper.

[0010] Preferably, the limiting assembly includes a pressure rod, a push rod, a return spring, a limit block, a placement groove, and a limit groove.

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-5 This application is described in further detail.

[0024] The present application embodiment discloses a measuring ruler for civil engineering. Figure 1-5 A measuring ruler for civil engineering, comprising a winding box 1, a measuring ruler 2 is arranged in the winding box 1, and a right-angle stopper 9 is arranged at one end of the measuring ruler 2 so that the end of the measuring ruler 2 can be extended to slide longitudinally to be flush with the non-scale display side of the measuring ruler 2;

[0025] It should be noted that one end of the measuring ruler 2 is wound up in the winding box 1 (not shown in the figure) through a torsion spring. The winding of the measuring ruler 2 can refer to GARANT 462012 5 tape measure;

[0026] By adopting the above technical solution, when it is necessary to measure the height of two vertical planes, the right-angle stopper 9 can be slid so that the bottom surface of the right-angle stopper 9 is flush with the side of the measuring ruler 2 without scale display, so that the measuring ruler 2 can be completely fitted on the vertical plane, thereby ensuring the measurement accuracy of the measuring ruler 2.

The pressure rod 11 is fixed to one end of the push rod 12, and the other end of the push rod 12 is fixed to one side of the limit block 15. The placement groove 16 is provided on the slider 2 13, the reset spring 14 is located between the slider 2 13 and the limit block 15, and the limit block 15 is clearance-matched with the placement groove 16. The limit groove 18 is provided at both ends of the bottom of the slide groove 3 17, the reset spring 14 and the limit block 15 are both located in the limit groove 18, and a slide groove 2 10 is provided on the right-angle stopper 9, and the push rod 12 is slidably arranged in the slide groove 2 10;

[0028] It should be noted that the second slide groove 10 is connected to the third slide groove 17; by adopting the above technical scheme, when normal measurement is performed, the right-angle block 9 can be used as a fulcrum or play a limiting role in the measurement. When it is necessary to measure the vertical surface, the limit block 15 slides in the limit groove 18 by pressing the pressure rod 11 to push the push rod 12, and the reset spring 14 is squeezed until the limit block 15 coincides with the placement groove 16. At this time, the pressure rod 11 cannot be pushed, and the right-angle block 9 is slid along the second slide groove 10, so that the slider 2 13 slides along the third slide groove 17 to another limit groove 18. When the pressure rod 11 is not subjected to force, the reset spring 14 pushes the limit block 15 and the side wall of the limit groove 18 to fit the push rod 12 and the pressure rod 11 to reset. At this time, the bottom surface of the right-angle block 9 is flush with the side of the measuring ruler 2 without scale display.

[0029] Reference Figure 1 , 2 4, a reading assembly is sleeved on the measuring ruler 2, and the reading assembly includes a reading block 4, a marking block 5, a magnifying glass 6, and a level 7.

[0032] The implementation principle of a measuring ruler for civil engineering in the embodiment of the present application is as follows: when measurement is required, the right-angle stopper 9 is pulled to fit it with one side of the object to be measured. At this time, the side of the measuring ruler 2 without scale display fits with the object to be measured, and the winding box 1 and the reading block 4 are pulled to place the length of the measuring ruler 2 to the required length. At this time, the reading block 4 is located at the measured position, and the measuring position is marked by the marking block 5. At the same time, the method scale number corresponding to the magnifying lens 6 is read and recorded. When it is necessary to measure the vertical surface, the push rod 11 is pressed to make the limit block 15 coincide with the placement groove 16, and the right-angle stopper 9 is slid along the second slide groove 10, so that the second slider 13 slides along the third slide groove 17 to another limit groove 18. At this time, the bottom surface of the right-angle stopper 9 is flush with the side of the measuring ruler 2 without scale display, and the bottom surface of the right-angle stopper 9 is fit with the vertical surface of the surface to be measured, and the above measurement and reading steps are repeated.
