Description

Technical Field

[0001] The utility model relates to a measuring tool for the thickness of a concrete casting slab with adjustable length. Background Art

[0002] The thickness of a concrete casting slab refers to the thickness of a floor slab, a roof slab or other horizontal structural members formed by concrete casting during the building construction process. During or after the casting process, it is necessary to measure its thickness to ensure that the thickness of the concrete casting is controlled within the required range. Usually, a steel ruler is used to measure the thickness of the concrete, but it is not easy to read the value during the measurement process, and there is a risk of slipping out of the hand. Content of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a measuring tool for the thickness of a concrete casting slab with adjustable length, which can quickly measure the thickness of the casting slab by presetting the measurement value.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A measuring tool for the thickness of a concrete casting slab with adjustable length, including a sleeve and a ejector rod. One end of the sleeve is provided with a groove for installing the ejector rod. The ejector rod is installed in the groove and can move along the axial direction of the groove. A convex block is arranged on the outer diameter surface of the ejector rod, and an opening for the convex block to move is arranged on the sleeve. A limiting groove communicated with the opening is arranged on the sleeve, and an annular groove is arranged on the ejector rod.

[0005] As a further improvement of the utility model, a spring for ejection is arranged between the ejector rod and the bottom of the groove.

[0006] As a further improvement of the utility model, a plurality of limiting grooves and annular grooves are respectively arranged along the axial directions of the sleeve and the ejector rod.

[0007] As a further improvement of the utility model, a flat plate extending outwards is arranged on the outer diameter surface of the sleeve.

[0008] As a further improvement of the utility model, a through groove for tying a rope is arranged at one end of the ejector rod away from the spring.

[0009] The beneficial effects of the utility model: The thickness of the concrete casting slab can be quickly measured by extending out the ejector rod, and the annular groove on the ejector rod can help the operator quickly read whether it meets the numerical range. Description of the Drawings

[0010] Figure 1 It is a schematic diagram of the overall structure of an embodiment of the utility model.

[0011] Reference numerals: 1, sleeve; 2, ejector rod; 3, bump; 4, limit groove; 5, annular groove; 6, spring; 7, flat plate; 8, through groove. Detailed implementation mode

[0012] The following will further elaborate on the present utility model in combination with the embodiments given in the drawings.

[0013] Refer to Figure 1 As shown, a thickness measuring tool for concrete pouring plates with adjustable length includes a sleeve 1 and an ejector rod 2. One end of the sleeve 1 is provided with a groove for installing the ejector rod 2. The ejector rod 2 is installed in the groove and can move along the axial direction of the groove. A bump 3 is provided on the outer diameter surface of the ejector rod 2. An opening for the bump 3 to move is provided on the sleeve 1. When the ejector rod 2 extends, it drives the bump 3 to slide along the opening. A limit groove 4 communicating with the opening is provided on the sleeve 1. The setting of the limit groove 4 facilitates the positioning of the ejector rod 2 on the sleeve 1 and prevents the ejector rod 2 from retracting after contacting the bottom. An annular groove 5 is provided on the ejector rod 2. The height of the annular groove 5 on the ejector rod 2 is customized according to the actual required length, and the width of the axial distance of the annular groove 5 is determined according to the deviation value of the thickness. During use, the ejector rod 2 is extended and the bump 3 is slid into the limit groove 4, and the ejector rod 2 is inserted to the bottom of the poured concrete. Then it is pulled out and observed whether the position where the concrete adheres is within the range of the annular groove 5.

[0014] A spring 6 for ejection is provided between the ejector rod 2 and the bottom of the groove. The setting of the spring 6 enables the bump 3 to be reliably pressed in the limit groove 4 without the need to press it with fingers. Such a setting can make it more convenient for the operator to measure. A plurality of limit grooves 4 and annular grooves 5 are respectively arranged along the axial directions of the sleeve 1 and the ejector rod 2. A plurality of annular grooves 5 are arranged on the ejector rod 2 according to the measurement requirements to measure the pouring thicknesses of different requirements. An outwardly extending flat plate 7 is provided on the outer diameter surface of the sleeve 1. The flat plate 7 is used to abut against a plane. In actual application, the flat plate 7 can be abutted against the plane by stepping on the flat plate 7, so that the ejector rod 2 can be relatively horizontal with the ground. To prevent the bump 3 from disengaging from the limit groove 4 due to vibration or overturning during the transportation process of the tool, resulting in the ejector rod 2 flying out of the sleeve 1, a through groove 8 for tying a rope is provided at one end of the ejector rod 2 away from the spring 6. The ejector rod 2 is tied and fixed on the flat plate 7 through a rope to facilitate transportation or storage.

[0015] The above are only the preferred embodiments of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
