Description

Technical Field

[0001] This utility model relates to the field of concrete testing technology, and in particular to a concrete slump spread test instrument. Background Technology

[0002] Concrete slump spread testing can reveal the fluidity, cohesiveness, and water retention of concrete. Currently, during testing, when pouring concrete into the conical bucket, it easily overflows from the gap between the bucket and the testing platform during tamping. This overflow affects the accuracy of subsequent measurements. Furthermore, to ensure the bucket is completely filled, concrete often overflows from the top, causing concrete to adhere to the outer wall of the bucket, making operation difficult, and the overflowing concrete flowing onto the testing platform can also affect measurements. Utility Model Content

[0003] This utility model provides a concrete slump spread test instrument to overcome the shortcomings of the prior art and solve the problem of concrete easily overflowing from the bottom during pouring, which has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A concrete slump spread test instrument includes a rectangular plate, a pair of mutually symmetrically arranged limiting mechanisms on the plate, and a cone on the plate. Both ends of the cone are open, and the diameter of the upper end of the cone is smaller than that of the lower end. A lower ring is welded to the outer periphery of the lower end of the cone, and the lower ring is placed on a flat plate. An upper ring is welded to the upper end of the outer periphery of the cone, and an upper extension ring is welded to the outer periphery of the upper ring.

[0005] Furthermore, a pair of handle rings are welded to the outer periphery of the upper extension ring.

[0006] Furthermore, the limiting mechanism includes an end plate welded to the upper side of the plate. A pair of movable rods are movably mounted on the end plate. An end pull plate is fixed to the outer end of the movable rod by a nut. The end pull plate is located on the outer side of the end plate. An inner plate strip is connected to the inner end of the movable rod by a thread. A limiting plate is welded to the lower side of the inner plate strip. An arc-shaped groove with a semi-circular structure is opened on the inner side of the limiting plate. The periphery of the arc-shaped groove abuts against the outer periphery of the lower ring.

[0007] Furthermore, a limiting ring with an L-shaped cross-section is welded to the upper wall of the lower ring, and an arc-shaped insert ring is formed on the periphery of the arc groove of the limiting plate, which is inserted into the outer periphery of the limiting ring.

[0008] Furthermore, a concave handle is welded to the outer wall of the end plate.

[0009] Furthermore, a limit screw is connected to the end plate by a thread, and a limit plate is rotatably provided on the outer end of the limit screw. The inner wall of the limit plate abuts against the outer wall of the end pull plate.

[0010] The advantages of the above technical solution are: This utility model uses a pair of limiting plates and insert rings to limit the lower end of the cone. This not only limits the cone and prevents it from shifting or tipping over during tamping, but also ensures a sealing effect during limiting by the cooperation of the limiting rings and insert rings, so as to minimize the amount of concrete overflow.

[0011] Secondly, the upper ring and upper extension ring can intercept and collect the concrete overflowing from the upper end of the cone to prevent it from flowing downwards.

[0012] Thirdly, by pulling and moving the limiting plate and the limiting rotating plate, not only can the limiting of the cone be quickly canceled, but the stability after the limiting is also ensured. Attached Figure Description

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a further detailed description of this utility model in conjunction with the accompanying drawings.

[0014] Fig. 1 A three-dimensional structural diagram of one embodiment is shown.

[0015] Fig. 2 A cross-sectional view of the cone-shaped device is shown. Detailed Implementation

[0016] like Figs. 1-2 As shown, a concrete slump spread test instrument includes a rectangular plate 1, a pair of mutually symmetrically arranged limiting mechanisms on the plate 1, and a cone 3 on the plate 1. Both ends of the cone 3 are open, and the diameter of the upper end of the cone 3 is smaller than the diameter of the lower end. A lower ring 33 is welded to the outer periphery of the lower end of the cone 3. The lower ring 33 is placed on the plate 1. An upper ring 30 is welded to the upper end of the outer periphery of the cone 3. An upper extension ring 31 is welded to the outer periphery of the upper ring 30. A pair of handle rings 32 are welded to the outer periphery of the upper extension ring 31.

[0017] The limiting mechanism includes an end plate 2 welded to the upper side of the plate 1. A pair of movable rods 20 are movably mounted on the end plate 2. An end pull plate 22 is fixed to the outer end of each movable rod 20 by a nut. The end pull plate 22 is located on the outer side of the end plate 2. An inner plate strip 21 is threaded onto the inner end of each movable rod 20. A limiting plate 26 is welded to the lower side of the inner plate strip 21. A semi-circular arc-shaped groove is formed on the inner side of the limiting plate 26, and the periphery of the arc-shaped groove abuts against the outer periphery of the lower ring 33. A limiting ring 34 with an L-shaped cross-section is welded to the upper wall of the lower ring 33. An arc-shaped insert ring 27 is formed on the periphery of the arc-shaped groove of the limiting plate 26 and is inserted into the outer periphery of the limiting ring 34. A concave handle 23 is welded to the outer wall of the end pull plate 22.

[0018] A limit screw 24 is threadedly connected to the end plate 2. A limit plate 25 is rotatably provided on the outer end of the limit screw 24. The inner wall of the limit plate 25 abuts against the outer wall of the end pull plate 22.

[0019] In this embodiment, the operator places the cone 3 at the geometric center of the plate 1 and between it and the limiting plate 26.

[0020] Then, the operator pushes the end pull plate 22 to move the limiting plate 26 inward, so that the periphery of the arc groove abuts against the outer periphery of the lower ring 33, and inserts the insertion ring 27 into the outer periphery of the limiting ring 34.

[0021] Next, the limiting plate 25 is rotated so that the inner wall of the limiting plate 25 abuts against the outer wall of the end pull plate 22.

[0022] Then, concrete is poured from the top of the cone 3 downwards. During the pouring process, the concrete is tamped until the top of the concrete is flush with the top of the cone 3.

[0023] Next, the limit plate 25 is removed, and the limit plate 26 is pulled outward. Then, the cone 3 is lifted upward, and the measurement operation is performed.

[0024] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
