Description

Technical Field

[0001] This utility model relates to the technical field of concrete testing equipment, and in particular to a slump spread testing device. Background Technology

[0002] Slump is a method and indicator for measuring workability. The slump test is conducted as follows: Concrete mixture is filled into a standard conical slump cone according to specified methods. After filling and leveling, the cone is lifted vertically upwards and moved aside. The concrete mixture will slump due to its own weight. The dimension of the slump is then measured; this dimension is the slump, and as a flowability indicator, a larger slump indicates better flowability.

[0003] When the slump is greater than 220 mm, the slump alone cannot accurately reflect the fluidity of concrete. The average diameter of the expanded concrete, i.e., the slump spread, is used as a fluidity indicator. The measuring ruler used in current standards, due to its base (approximately 100 mm in diameter), cannot be directly used to measure the slump spread of concrete with a slump greater than 220 mm. If a person uses a handheld steel ruler, the thickness of the disc formed after the concrete collapses makes it difficult to control the levelness of the ruler and its alignment with the concrete diameter. Combined with visual observation, operational errors are easily introduced, resulting in low measurement accuracy, which needs improvement. Utility Model Content

Detailed Implementation

[0032] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0033] Example 1

[0034] As attached Figure 1-7 As shown, a slump spread test device includes a scale 2 with measuring scale markings 1, a first support assembly 3 fixed to one end of the scale 2, and a second support assembly 4 slidably mounted on the scale 2; the scale 2 has an I-shaped cross section, which ensures that the scale has sufficient bending strength, light weight, and also protects the measuring scale markings 1, extending its service life;

[0035] The first bracket assembly 3 includes a fixed base 61 fixed to the scale 2, and a fixed support rod 62 fixed to the fixed base 61 and extending downward.

[0036] The second bracket assembly 4 includes a sliding seat 51 that is slidably fitted onto the scale 2, and a movable support rod 52 that is fixed to the sliding seat 51 and extends downward.

[0037] The adjacent sides of the fixed support rod 62 and the movable support rod 52 are called the inner sides. The length between the inner sides is equal to the value of the measurement scale mark 1 indicated by the movable seat (also called the measured value); that is, the inner sides of the fixed support rod 62 and the movable support rod 52 correspond to the zero value and the measured value of the measurement scale mark 1, respectively.

[0038] When the lower ends of both the fixed support rod 62 and the movable support rod 52 are in contact with the ground, the ruler 2 is parallel to the ground.

[0039] As a preferred technical solution in this embodiment, the movable support rod 52 and the sliding seat 51 are connected in a detachable manner. Specifically, the sliding seat 51 is provided with a connecting part 53, the lower end of the connecting part 53 is provided with a regular polyhedral groove 54, the upper end of the movable support rod 52 is provided with a snap-fit ​​section 55 that matches the groove 54, the connecting part 53 is provided with a through hole 56 that communicates with the groove 54, and a positioning bead 57 is fixedly connected to the through hole 56; the snap-fit ​​section 55 is provided with a positioning hole 58 that cooperates with the positioning bead 57.

[0040] During assembly and disassembly, by inserting the snap-fit ​​section 55 into the snap-fit ​​groove 54, the positioning bead 57 automatically snaps into the corresponding positioning hole 58 under the elastic action, thereby achieving a stable connection between the movable support rod 52 and the sliding seat 51. When disassembly is required, simply pull the snap-fit ​​section 55 in the opposite direction to disengage the positioning bead 57 from the positioning hole 58, and the movable support rod 52 can be quickly separated from the sliding seat 51. The whole process is simple to operate and reliable in connection, improving the assembly efficiency and ease of use of the device.

[0041] As a preferred technical solution in this embodiment, the fixed support rod 62 and the fixed seat 61 are connected in a detachable manner. This detachable connection method is the same as the detachable connection method between the movable support rod 52 and the sliding seat 51. Obviously, other commonly used quick-release methods such as threaded connections can also be used.

[0042] As a preferred technical solution in this embodiment, the fixing base 61 is fitted onto the scale 2, the fixing base 61 is provided with a connecting hole 63, and a screw 64 is provided on the connecting hole 63. The screw 64 is threadedly connected to the scale 2 to facilitate quick assembly and disassembly.

[0043] During measurement, the device is first placed on a flat surface, ensuring that the lower ends of both the fixed support rod 62 and the movable support rod 52 are in contact with the ground simultaneously, keeping the scale 2 parallel to the ground. Simultaneously, the inner side of the fixed support rod 62 is aligned with the edge of the concrete. Then, by sliding the sliding seat 51 in the second support assembly 4, the movable support rod 52 is moved along the scale 2, adjusting it relative to the fixed support rod 62 of the first support assembly 3 to the position of the expanded edge of the slump of the concrete to be measured. Since the distance between the inner sides of the fixed support rod 62 and the movable support rod 52 is the measured value, this value can be directly read from the corresponding measurement scale mark 1 on the scale 2 by the sliding seat 51, thus quickly and accurately obtaining the slump expansion value of the concrete. During use, the scale 2 adopts an I-shaped cross-section design, which not only ensures structural strength and reduces overall weight but also protects the scale marks. The protective function extends the service life of the device. In addition, the movable support rod 52 and the sliding seat 51 in the second bracket assembly 4 adopt a snap-fit ​​quick-release structure. After the snap-fit ​​section 55 is inserted into the slot 54 of the connecting part 53 and rotated, the positioning bead 57 automatically snaps into the positioning hole 58 to achieve a stable connection. Disassembly only requires rotating in the opposite direction and pulling to separate them. The operation is simple and the connection is reliable. Similarly, the fixed support rod 62 and the fixed seat 61 of the first bracket assembly 3 also adopt the same or similar quick-release structure, which is convenient for disassembly, assembly and carrying. The fixed seat 61 is locked to the scale 2 by screws 64, which further improves the stability and adjustment flexibility of the overall structure, making the whole measurement process more efficient, accurate and convenient for on-site operation.

[0044] Example 2

[0045] As attached Figure 8-11 As shown, a slump spread test device is provided. To improve ease of use, this embodiment is an improvement on embodiment 1. Specifically, the lower end of the movable support rod 52 is fixedly connected to a movable support plate 5, and the lower end of the fixed support rod 62 is fixedly connected to a fixed support plate 6; the inner side of the movable support plate 5 is aligned with the inner side of the movable support rod 52, and the inner side of the fixed support plate 6 is aligned with the inner side of the fixed support rod 62.

[0046] As a preferred technical solution in this embodiment, in order to facilitate storage, the movable support plate 5 and the movable support rod 52 are connected in a detachable manner. Specifically, the movable support plate 5 is provided with a docking groove 7 at its bottom and a connecting post 8 that matches the docking groove 7 at its upper end. The connecting post 8 and the docking groove 7 are connected by magnetic attraction.

[0047] Accordingly, for ease of storage, the fixed support plate 6 and the fixed support rod 62 are also connected in a detachable manner. This detachable connection method is the same as that used for the movable support plate 5 and the movable support rod 52.

[0048] This invention optimizes and improves upon Embodiment 1, providing a concrete slump expansion testing device with a reasonable structure and convenient use. By setting detachable movable support plate 5 and fixed support plate 6 at the lower ends of movable support rod 52 and fixed support rod 62 respectively, with the inner sides of the support plates aligned with the corresponding inner sides of the support rods, their inner edges are parallel, allowing for faster tangential contact with the outer edge of the expanded concrete, thereby improving measurement efficiency and accuracy. Furthermore, the movable support plate 5 and movable support rod 52, and the fixed support plate 6 and fixed support rod 62, both employ a magnetic detachable connection structure. Specifically, magnetic attraction is achieved through the mating groove 7 and connecting column 8, ensuring a stable connection, simple operation, and easy disassembly and storage, enhancing the device's portability and reusability. Simultaneously, when operated by one person, after measurement and adjustment, the movable support plate 5 and fixed support plate 6 can be effectively supported on the ground without human assistance, facilitating reading and recording by the operator. This structural design effectively simplifies the on-site operation process, enhances the stability and intuitiveness of the measurement process, and is suitable for rapid testing needs in various construction site environments, possessing good application prospects and promotional value.

[0049] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
