[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.
[0003] The slump test is an architectural test experiment, which is mainly used to control the water retention, fluidity and cohesion of concrete. When using it, place the cylinder on a rigid horizontal board that does not absorb water, then step on the pedals on both sides, and add the concrete sample into the slump cylinder. Conventional slump cylinders often have many problems in use. For example, when the parts are used separately, they must be aligned and used together.

[0031] Example 1
[0032] This embodiment provides a concrete slump detection device, such as Figure 1 As shown, it includes a collapse cone 1, a material plate 2, a scale 3 and a scale fixing component 4 that are used together.
[0033] The collapse cone 1 adopts a truncated cone-shaped cylinder structure with two open ends, and the area of the top end is smaller than the area of the bottom end.
[0034] like Figure 2-Figure 3 As shown, a plurality of limiting members 5 are arranged at equal intervals along the circumferential direction at the bottom end of the collapse cone 1, and the limiting members 5 have limiting grooves.
[0035] In the present embodiment, on the cross section perpendicular to the circumference of the collapse cone 1, the cross-sectional shape of the limit groove is an inverted V shape. When this arrangement is adopted, the limit member 5 is composed of a first limit portion and a second limit portion, the top ends of the first limit portion and the second limit portion are cross-connected and distributed at a set acute angle, and a limit groove is formed between the first limit portion and the second limit portion.
[0036] It is understandable that the cross-sectional shape of the limiting groove may also be other shapes, such as semicircular or rectangular, etc., and those skilled in the art may set it according to actual needs.
[0037] Preferably, six limiting members 5 are provided at the bottom end of the collapse cone 1 .
[0038] The outer surface of the collapse cone 1 is provided with a storage bin 6 for storing the scale 3 and the scale fixing component 4. When not in use, the scale 3 and the scale fixing component 4 can be placed in the storage bin 6, thereby avoiding the loss of parts of the detection device and ensuring the normal progress of the test.
[0039] Furthermore, two storage bins 6 are provided, and the two storage bins 6 are used to store the scale 3 and the scale fixing component 4 respectively.
[0040] Two handles 7 are also fixed on the body of the collapse cone 1. The two handles 7 are arranged at an interval of 180 degrees, so that the test personnel can lift the collapse cone 1 conveniently.
[0041] like Figure 4 As shown, the material plate 2 is a 50cm*50cm steel plate, and a plurality of limit blocks 8 matching the limit grooves are provided on the upper surface of the material plate 2. Preferably, the limit blocks 8 are made of rubber material.
[0042] Since the limiting groove is an inverted V-shaped structure, the limiting block 8 adopts an inverted V-shaped structure matching the limiting groove, and the limiting block 8 can be inserted into the limiting groove, and the space between two adjacent limiting members 5 allows the limiting block 8 to be placed.
[0043] In this embodiment, the collapse cone 1 is placed on the upper surface of the material plate 2, and the limit block 8 is placed between two adjacent limit members 5. The collapse cone 1 is rotated so that the limit block 8 can be stuck in the limit groove to achieve the positioning and fixation of the collapse cone 1 and the material plate 2. The limit block 8 is stuck in the limit groove, which plays a limiting role on the collapse cone 1, avoiding the problem of being unable to accurately measure the slump of concrete due to the tilt of the collapse cone 1 when tamping concrete. Moreover, after the collapse cone 1 is placed on the material plate 2, the limit block 8 can be stuck in the limit groove by rotating the collapse cone 1, and the operation is convenient and simple.
[0044] The ruler 3 is a rigid ruler with scale lines on its surface.
[0045] like Figure 5As shown, the scale fixing component 4 includes a fixing rod, one end of which is provided with an opening 9 matching the scale, and the scale 3 can pass through the opening 9 and move in a direction perpendicular to the fixing rod.
[0046] The fixing rod is also provided with a locking piece, and the locking piece is used to lock and fix the fixing rod and the ruler.
[0047] The locking member is a locking bolt 10 arranged on one side of the opening. The locking bolt 10 is threadedly connected to the fixing rod. The rod of the locking bolt 10 can extend into the opening and press the scale 3 against the hole surface of the opening 9.
[0048] Compared with using a tape measure, the ruler 3 cooperates with the fixing rod through the opening 9, which can ensure the verticality between the ruler 3 and the fixing rod, thereby ensuring the accuracy of the measurement result.
[0049] Preferably, a paddle 11 is slidably connected in the opening 9, and a flexible pad is provided on one side of the paddle 11. In this embodiment, the flexible pad is a rubber pad 12. The other side of the paddle 11 is used to contact the rod of the locking bolt 10. By rotating the locking bolt 10, the rod of the locking bolt 10 can push the paddle 11 to move, and the paddle 11 presses the scale 3 through the rubber pad 12, thereby avoiding damage to the surface of the scale 3.
[0050] A plurality of saw teeth 13 are disposed on the side surface of the fixing rod. The plurality of saw teeth 13 are disposed along the length direction of the fixing rod, and tooth grooves are formed between adjacent saw teeth 13 .
[0051] Furthermore, the sawtooth 13 is a right-angled triangle sawtooth, and correspondingly, the tooth groove is also a right-angled triangle tooth groove, wherein the surface corresponding to one right-angled side is fixedly connected to the side of the fixed rod, and the surface corresponding to the other right-angled side is closer to the opening than the surface corresponding to the hypotenuse.
[0052] Two fixed blocks 14 are arranged at the top of the collapse cone 1. The fixed blocks 14 are rectangular blocks and are arranged 180° apart. Both fixed blocks are provided with protrusions 15 matching the tooth grooves. The protrusions 15 are arranged at the ends of the fixed blocks 14. Since the tooth grooves are right-angled triangles, the protrusions 15 are right-angled triangle protrusions.
[0053] When placing a fixing rod on the top of the collapse cone 1, the fixing rod is placed on the top surface of the fixing block 14, and the protrusion 15 is placed in the right-angled triangle tooth groove. The fixing rod is moved so that the surface corresponding to the hypotenuse of the sawtooth 13 fits with the surface corresponding to the hypotenuse of the protrusion 15, thereby completing the fixation of the fixing rod.
[0054] The projections 15 fall into different tooth grooves, and the position of the fixing rod relative to the collapse cylinder 1 can be adjusted so that the scale 3 is located directly above the highest point of the concrete sample after collapse.
[0055] Furthermore, through the cooperation between the protrusion 15 and the sawtooth 13, the fixing rod can only move in one direction, thereby ensuring the stability of the fixing rod and the scale 3 during measurement and ensuring the accuracy of the measurement result.
[0056] The method for using the detection device of this embodiment comprises the following steps:
[0057] Step 1: Wet the slump cone 1 and the vibrating rod, and place the material plate 2 on a relatively flat ground.
[0058] Step 2: Place the slump cone 1 on the material plate 2, rotate the slump cone 1, so that the limit block 8 is stuck in the limit groove, so that the slump cone 1 and the material plate 2 are tightened and engaged.
[0059] Step 3: Use a shovel to evenly load the concrete sample into the slump cone 1 in three layers, so that the height of each layer after compaction is about one-third of the height of the slump cone. Use a vibrator to evenly tamp each layer from the outside to the center along the spiral direction 25 times on the cross section. When tamping the concrete at the edge of the slump cone 1, the tamping rod can be slightly tilted. When tamping the bottom layer, the tamping rod should penetrate the entire depth. When tamping the second and top layers, the vibrator should penetrate the current layer to the surface of the next layer. When pouring the top layer, the concrete should be poured to a height higher than the top opening of the slump cone 1. During the tamping process, if the concrete sinks to a level lower than the top opening of the slump cone 1, it should be added at any time. After tamping the top layer, scrape off the excess concrete and smooth it with a knife.
[0060] Step 4: Clear the concrete on the bottom edge of the slump cone 1, rotate the slump cone 1 so that the limit block 8 is separated from the limit groove, and lift the slump cone 1 through the handle 7.
[0061] Step 5: Place the collapse cone 1 on the material plate 2, take out the scale 3 and the scale fixing component 4 from the storage bin 6, place the fixing rod on the upper surface of the fixing block 14, and the tooth groove set on the fixing rod cooperates with the protrusion 15, so that after the protrusion 15 and the serration 13 are fitted, the opening 9 is located directly above the highest point of the concrete specimen after collapse.
[0062] Step 6: Take out the ruler 3 from the storage bin, pass the ruler 3 through the opening 9, move the ruler 3 so that its bottom end contacts the highest point of the concrete test block after collapse, then turn the locking bolt 10 to fix the ruler 3 to the fixing rod, read and record through the ruler 3 to obtain the slump of the concrete.
[0063] Step 7: After the measurement is completed, wipe off the stains on the surface of the ruler 3 and the ruler fixing part 4, and then put them back into the storage bin 6.
[0064] The device of this embodiment is easy to operate and can be completed by one person, avoiding the loss of the ruler and the ruler fixing parts during measurement, and the tipping of the slump cylinder and the side leakage of concrete when the concrete specimen is filled, saving labor and improving the efficiency of the slump test.
[0065] Although the above describes the specific implementation methods of the utility model in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
