Technical Field

[0001] The utility model relates to the technical field of engineering cost budget measurement, in particular to a measuring device for construction engineering cost budget. Background Art

[0002] The project cost refers to the estimated or actual construction expenses of the project during the construction period. In the budgeting process of the project cost, the staff needs to measure the various indicators of the building at the construction site, and then calculate the accurate project construction cost based on the measured results. In the measurement process, the most commonly used measuring tool is the easy-to-carry steel tape measure, which is used to accurately measure the walls, ground and other locations of the building.

[0003] However, the most common problem with existing steel tape measures is that when a single person is measuring long-distance dimensions, the end of the steel tape measure cannot be stably positioned at the location to be measured, and the steel tape measure often slips during the measurement process.

[0004] Therefore, in view of the above-mentioned problems, the present technical solution proposes a measuring device for construction project cost estimation. Utility Model Content

The plate hook and the splint are used to connect and position the magnet plate with the magnetic metal, the suction cup base plate is adsorbed and positioned with the smooth and tidy position, the enlarged plate hook is frictionally positioned with the rough position, and the splint is clamped and positioned with the plate-shaped position. That is, under the action of the magnet plate, the suction cup base plate, the enlarged plate hook and the splint, the end of the steel tape measure can be stably installed at different types of positions, so that it can perform long-distance and accurate size measurement. At the same time, the detachable connection between the extension piece and the steel tape measure does not affect the normal use of the steel tape measure when it is in conjunction with the positioning hook, which greatly improves the scope of use of the steel tape measure for single-person operation for construction project cost budget measurement to a certain extent.

[0007] Compared with the prior art, the beneficial effects of the utility model are as follows: on the basis of the existing steel tape measure, a magnet plate, a suction cup base plate, an enlarged plate hook and a clamping plate with adjustable installation positions are detachably installed, and the functions of positioning the magnet plate, the suction cup base plate, the enlarged plate hook and the clamping plate at different positions to be measured are utilized to ensure that the device can be used by a single person to perform stable measurements of long-distance buildings, thereby improving the scope of use and operability of the device, and greatly improving the efficiency of measuring the cost budget of construction projects to a certain extent.

[0016] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0017] See also Figure 1-Figure 3 A measuring device for construction engineering cost budget includes a steel tape measure 10 and a positioning hook 11; the positioning hook 11 is vertically fixedly installed at the end of the steel tape measure 10, and the end of the steel tape measure 10 away from the positioning hook 11 is connected to the steel tape measure box. The vertical connection structure of the positioning hook 11 and the steel tape measure 10 is used to locate the end position of the steel tape measure 10 to be measured over a short distance. A through hole is opened in the middle of the positioning hook 11, and an extension piece is detachably installed in the through hole. A positioning piece is installed on the side of the extension piece away from the steel tape measure 10, and the positioning piece includes a magnet plate 12, a suction cup base plate 13, an expansion plate hook 14, and a clamping plate 15, which are annularly distributed on the outside of the end of the extension piece. The plate 12 is connected and positioned with the magnetic metal by magnetic attraction, the suction cup base plate 13 is adsorbed and positioned with the smooth and tidy position, the enlarged version hook 14 is frictionally positioned with the rough position, and the clamping plate 15 is clamped and positioned with the plate-shaped position. That is, under the action of the magnet plate 12, the suction cup base plate 13, the enlarged version hook 14 and the clamping plate 15, it is ensured that the end of the steel tape measure 10 can be stably installed at different types of positions, so that it can perform long-distance and accurate size measurement. At the same time, the detachable connection between the extension piece and the steel tape measure 10 does not affect the normal use of the steel tape measure 10 when it is coordinated with the positioning hook 11, which greatly improves the use scope of the steel tape measure 10 for single-person operation for construction project cost budget measurement to a certain extent.

[0018] In the embodiment of the present invention, a corrugated channel is provided on the side of the positioning hook 11 that contacts the position to be measured, so as to increase the contact friction with the position to be measured; the magnet plate 12, the suction cup base plate 13, the enlarged plate hook 14, the clamping plate 15 and the extension part are telescopically connected to facilitate adjustment of the appropriate distance according to the depth of the position to be positioned, so that the magnet plate 12, the suction cup base plate 13, the enlarged plate hook 14 and the clamping plate 15 can be fully and accurately contacted and positioned with the position to be measured.

[0019] In one embodiment of the present invention, see Figure 4The extension piece includes a threaded barrel 22 inserted into the through hole, and the end of the threaded barrel 22 facing the steel tape measure 10 is threadedly connected with a fastening screw 23, and a limit block 24 is installed at the end of the fastening screw 23. The diameter of the limit block 24 is larger than the through hole, that is, the limit block 24 is controlled to be connected or separated from the threaded barrel 22 by rotating the fastening screw 23, thereby ensuring the plug-in fixation or separation release between the threaded barrel 22 and the through hole;

[0020] Specifically, a limit block groove 25 is provided on the positioning hook 11 around the through hole, and the limit block groove 25 is used to store the limit block 24. The depth of the limit block groove 25 is consistent with the thickness of the limit block 24, so as to ensure that after the threaded barrel 22 is inserted into the through hole and the limit block 24 fixes the threaded barrel 22, the depth between the limit block 24 and the inner side surface of the positioning hook 11 is consistent;

[0021] It should be noted that the thickness of the positioning hook 11 in the present technical solution is greater than the thickness of the positioning hook 11 at the end of the existing steel tape measure, that is, it provides the possibility for the installation and connection of the threaded tube 22, the outer end magnet plate 12, the suction cup base plate 13, the enlarged version hook 14, and the clamping plate 15. The increase in the thickness of the positioning hook 11 does not affect the normal measurement and use of the steel tape measure 10. The error in the size of the end of the steel tape measure 10 can be avoided by making corresponding calculations based on the actual thickness of the positioning hook 11.

[0022] As a preferred embodiment of the present invention, a circular fixing block is installed at the end of the threaded barrel 22 away from the limit block 24, and telescopic members are installed on the circumferential outer wall of the circular fixing block at equal intervals through connecting blocks, and the ends of the telescopic members are respectively fixedly connected to the magnet plate 12, the suction cup base plate 13, the enlarged plate hook 14, and the clamping plate 15, that is, the extension position of the magnet plate 12, the suction cup base plate 13, the enlarged plate hook 14, and the clamping plate 15 is adjusted by adjusting the distance of the telescopic member;

[0023] Specifically, the telescopic part includes a screw barrel 19 placed between the connecting block and the magnet plate 12, the suction cup substrate 13, the enlarged plate hook 14, and the clamping plate 15. The two ends of the screw barrel 19 are threadedly connected with screws 20. The ends of the screws 20 away from the screw barrel 19 are respectively fixedly connected to the adjacent connecting block, magnet plate 12, suction cup substrate 13, enlarged plate hook 14, and clamping plate 15. That is, the depth of the screws 20 at both ends placed in the screw barrel 19 is adjusted by manually rotating the screw barrel 19, thereby adjusting the overall length of the screw barrel 19 and the screw 20, and then adjusting the position of the end magnet plate 12, suction cup substrate 13, enlarged plate hook 14, and clamping plate 15.

[0024] Among them, a suction cup 21 is installed on the side of the suction cup substrate 13 facing the steel tape measure 10, and the suction function of the suction cup 21 is used to stably position the suction cup substrate 13 and the position to be measured; the enlarged version hook 14 is set to a rectangular plate structure, and a uniformly distributed corrugated strip is opened on the side facing the steel tape measure 10, and the corrugated strip is used to increase the contact friction with the position to be measured; the clamping plate 15 includes a mounting block fixed to the end of the screw barrel 19, and two parallel clamping plates are slidably connected to the side of the mounting block away from the screw barrel 19, and a slider 18 is installed on the end of the clamping plate facing the fixed block, and a sliding groove 17 is opened on the fixed block corresponding to the slider 18, and the slider 18 slides along the sliding groove 17, and at the same time, a plurality of springs 16 are uniformly elastically connected between the inner sides of the two clamping plates close to the fixed block, and the elastic action of the spring 16 is used to control the two clamping plates to be distributed at a certain distance, so that when the clamping plate 15 needs to be clamped and fixed, the cooperation of the two clamping plates and the spring 16 can be used to achieve fast and stable installation.

[0025] The working principle of the utility model is: when in use, different positioning structures are selected for positioning measurement according to the type of the building position to be measured. For short-distance measurement that can be operated by one person with both hands, the measurement can be directly carried out through the cooperation of the positioning hook 11 and the steel tape measure 10. When long-distance single-operation measurement is required, the threaded barrel 22 is first inserted into the through hole, and then the limit block 24 is connected to the threaded barrel 22 by rotating the fastening screw 23, and then the limit block 24 is stored in contact with the limit block groove 25, so that the threaded barrel 22 is installed on the positioning hook 11, and then according to the type of the position to be measured, the magnet plate 12, the suction cup base plate 13, the enlarged version hook 14 or the clamping plate 15 is selected for stable positioning, and then the steel tape measure 10 is manipulated to measure the distance.

[0026] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
