[0024] The utility model will be further explained in detail in combination with the drawings.
[0025] As Figure 1 , Figure 2 The utility model discloses a concrete slump test cylinder, including collapse cylinder 1, hopper 2, slide rail 3, sliding block 4 and horizontal rod 5.
[0026] AsFigure 1 As shown in the drawings, the slump cone 1 is conical, and the lower end is tapered to the upper end. The lower end of the slump cone 1 is provided with a foot pedal 11 for stepping on the slump cone 1 to increase the stability of the slump cone 1 during work.
[0027] As shown in the drawings, Figure 1 , Figure 3 The funnel 2 is detachably arranged on the upper end of the slump cone 1. The upper end of the slump cone 1 is provided with an inner rim 12, and the lower end of the funnel 2 is provided with an outer rim 21. The inner rim 12 and the outer rim 21 are fixedly arranged in each other to quickly fix and stably connect the funnel 2, so as to facilitate the stable pouring of the concrete into the slump cone 1.
[0028] As shown in the drawings, Figure 1 The slide rail 3 is arranged on the side wall of the slump cone 1 along the generatrix direction of the slump cone 1, and the slide rail 3 is provided with a scale mark 31.
[0029] As shown in the drawings, Figure 1 , Figure 2 The sliding block 4 is slidingly connected to the slide rail 3, and the crossbar 5 is horizontally arranged on the slide rail 3. The crossbar 5 includes a plurality of pipe bodies 51 which are arranged in a sleeve connection manner. The crossbar 5 is arranged in a T-shaped cross section, and the lower end surfaces are flush with each other to realize the storage of the crossbar 5 and facilitate the carrying.
[0030] As shown in the drawings, Figure 1 , Figure 2 The end of the innermost pipe body 51 is provided with a pull plate 52 for conveniently pulling the crossbar 5 to stretch and contract. The pull plate 52 is provided with a hook 53, and the outermost pipe body 51 is provided with a clamping column 54 for hooking the hook 53 to fix the crossbar 5 after storage, so as to stably store and store the crossbar 5.
[0031] As shown in the drawings, Figure 1 , Figure 2 The outermost pipe body 51 is rotatably connected to the sliding block 4, and the outermost pipe body 51 is provided with a locking block 55. The sliding block 4 is provided with a locking groove 41 for embedding the locking block 55, and the sliding block 4 is slidingly connected with a pressing block 42 for pressing the locking block 55.
[0032] When the slump degree of the concrete needs to be tested, the slump cone 1 is placed on the ground, and then the funnel 2 is placed on the slump cone 1, and the inner rim 12 and the outer rim 21 are clamped to each other to quickly install the slump cone 1 and the funnel 2. Then step on the pedal, then pour the concrete into the slump cone 1 in batches, and then take down the funnel 2, and then pull the slump cone 1 to make the concrete automatically collapse.
