Description

Technical Field

[0001] The utility model relates to the technical field of measurement, and more particularly to a sleeve for measuring concrete volume. Background Art

[0002] Sleeve technology is usually not a traditional method used directly to measure length, but it plays an important role in concrete quality inspection and strength assessment. However, starting from the application background of sleeves in concrete structures, we can explore how it is indirectly related to the measurement and quality control of concrete cubic length. When measuring the length of concrete cubic length, commonly used tools include steel rulers, tape measures, laser rangefinders, etc. These tools each have their own advantages and disadvantages. For example, steel rulers and tape measures are relatively inexpensive and easy to carry, but the measurement distance is limited and the accuracy may be affected by human factors. Laser rangefinders have the advantages of long measurement distance and high accuracy, but the price is relatively high. Therefore, when choosing a measuring tool, it is necessary to make a comprehensive consideration based on the actual measurement needs and budget. Regardless of the measuring tool used, it needs to be calibrated before use to ensure the accuracy of the measurement results. The calibration process should be carried out strictly in accordance with relevant regulations, including checking whether the tool is intact and whether the measurement scale is clear and accurate.

[0003] Existing technology is insufficient: Accurate measurement of concrete cube length is fundamental to ensuring the safety of building structures. Inaccurate measurement can result in insufficient concrete, which in turn affects the structure's load-bearing capacity and stability, increasing the risk of cracking, deformation, and even collapse.

[0006] Furthermore, a pulley base is fixedly connected to the side surface of the second movable block, a supporting pulley is movably connected to the inner ring side wall of the pulley base, and anti-slip grooves are provided on the side surface of the supporting pulley.

[0019] The following will clearly and completely describe the technical solution of the present invention in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely examples. The concrete measuring sleeve involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] Reference Figures 1 to 5 The utility model provides a sleeve for measuring concrete volume, including a fixed block 3, a first movable block 301 being fixedly connected to the side of the fixed block 3, a first movable strut 302 being movably connected to the outer ring side wall of the first movable strut 302, a movable slider 303 being movably connected to the inner ring side wall of the first movable strut 302, a supporting spring 305 being fixedly connected to the side of the movable slider 303, a sliding rod 304 being movably sleeved on the inner ring of the movable slider 303, a second movable strut 306 being movably connected to the inner ring side wall of the movable slider 303, a second movable strut 306 being movably connected to the inner ring side of the second movable strut 306, a second movable block 307 being movably connected to the second movable block 307 being fixed to the side of the pulley base 4, and when being squeezed, the second movable strut 306 will be extended outward, driving the movable slider 303 to slide on the sliding rod 304.

[0021] Among them, the side of the second movable block 307 is fixedly connected to the pulley base 4, the inner ring side wall of the pulley base 4 is movably connected to the support pulley 401, and the side of the support pulley 401 is provided with anti-slip grooves 402. The design of the anti-slip grooves 402 increases the contact area and roughness between the support roller 401 and the surface of the concrete square pile, so that the support roller 401 can more effectively grasp the surface during rolling, thereby improving the friction coefficient.

[0022] The side of the fixing block 3 is fixedly connected to the main sleeve 1 , the side of the main sleeve 1 is fixedly connected to the main handle 101 , and the outer ring side wall of the main sleeve 1 is fixedly connected to the lock buckle 204 .

[0023] Among them, the outer ring side wall of the main sleeve 1 is fixedly connected with a folding hinge 205, and the inner ring side wall of the folding hinge 205 is threadedly connected with a fixing bolt 206. The folding hinge is mainly used for the main sleeve 1 and the auxiliary sleeve 2, and can fix them together at different angles. This connection is not only stable but also flexible, so that the connected items can be adjusted as needed.

[0024] The side surface of the folding hinge 205 is threadedly connected to the auxiliary sleeve 2, and the side surface of the auxiliary sleeve 2 is fixedly connected to the auxiliary handle 201.

[0025] Among them, the outer ring side wall of the auxiliary sleeve 2 is movably connected to a roller rangefinder 202, and the outer ring side wall of the auxiliary sleeve 2 is fixedly connected to a meter display screen 203. The roller rangefinder 202 includes a measuring head and a digital display screen. The measuring head is equipped with a roller to facilitate rolling on various surfaces. When the roller rolls on a smooth surface, the photoelectric sensor or other similar sensors in the measuring head will continuously record the number of rotations of the roller to calculate the number of meters.

[0026] The working principle of the present invention is as follows: when in use, the lock buckle 204 on the side of the main sleeve 1 is opened, and the auxiliary handle 201 and the main handle 101 are held by both hands respectively, and the auxiliary sleeve 2 and the main sleeve 1 are stretched open respectively, and they are clamped on the concrete square pile and then the lock buckle 204 is closed and clamped. When the main sleeve 1 and the auxiliary sleeve 2 are clamped on the concrete, the supporting pulley 401 will contact the surface of the concrete square pile, and the second movable block 307 is fixed to the side of the pulley base 4. After being squeezed, the second movable support rod 306 will extend outward, driving the movable slider 303 to slide on the sliding rod 304. Because of the action of the supporting spring 305, there will be a tensile expansion that will make the supporting pulley 401 tightly squeezed on the surface of the concrete. The sleeve has a total of Four such extrusion rollers cause the sleeve to engage with the surface of the concrete pile. Because this principle can be adapted to measure the length of concrete piles of various sizes, the provided roller distance meter 202 will also fit the surface of the concrete pile. By engaging with the end of the concrete pile, the user holds the auxiliary handle 201 and the main handle 101 with both hands and pushes on the concrete pile. At this time, the roller distance meter 202 will roll. The roller distance meter 202 includes a measuring head and a digital display screen. The measuring head is equipped with a roller to facilitate rolling on various surfaces. When the roller rolls on a smooth surface, the photoelectric sensor or other similar sensor in the measuring head will continuously record the number of rotations of the roller, thereby calculating the number of meters.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
