Description

Technical Field

[0001] The utility model relates to the technical field of storage equipment, in particular to a concrete test piece storage device. Background Art

[0002] In order to ensure the strength of concrete or concrete structures, it is necessary to extract materials from the concrete to make concrete specimens. The concrete specimens are used to measure the strength of concrete components. In engineering projects, many concrete specimens need to be made and placed in a curing room for curing. To save space, concrete specimen holders are currently made according to standard concrete specimen specifications. In this case, when encountering non-standard and tall concrete specimens, the concrete specimen holders need to be readjusted. In the prior art, for example, patent CN219770412U discloses a concrete specimen storage device in which a placement trough is fixed to a column by bolts. In order to place a tall concrete specimen, the bolts at the four connection points of the placement trough need to be removed, the placement trough needs to be raised, and then fixed to the column with bolts. This operation is cumbersome and difficult for one person to operate. Summary of the Invention

[0003] In view of the above-mentioned prior art, the present invention provides a concrete specimen storage device, and the problem to be solved is that it can store ordinary standard concrete specimens and can also store higher concrete specimens without disassembly.

[0004] To achieve the above-mentioned purpose, the technical solution of the embodiment of the utility model is implemented as follows:

[0005] A concrete specimen storage device includes a base plate and a multi-layer specimen frame, the specimen frame is fixed on the base plate, the specimen frame includes multiple horizontally arranged specimen boxes, the specimen box includes two front columns, two rear columns, a left support plate, a right support plate and a placement box, the left support plate is fixedly connected to the front column and the rear column on the left side, the right support plate is fixedly connected to the front column and the rear column on the right side, the left support plate and the right support plate are horizontally arranged, the placement box is used to place concrete specimens, and the placement box is slidably connected to the left support plate and the right support plate.

[0006] Furthermore, isolation plates are connected between the front column and the rear column on the left, between the front column and the rear column on the right, and between the two rear columns.

[0007] Furthermore, universal wheels are installed at the four corners of the base plate, and a foot brake is installed on one side of the universal wheel.

[0008] Furthermore, each edge of the base plate is installed with a supporting structure, which includes a connecting block, a knob, a threaded rod and a supporting block. The connecting block is fixedly connected to the base plate, and there is a threaded hole on the connecting block. The threaded rod passes through the threaded hole and is threadedly connected to the threaded hole. The knob is installed at the upper end of the threaded rod, and the support block is installed at the lower end of the threaded rod.

[0009] Furthermore, the bottom of the placement box is composed of cross-connected support bars.

[0010] Furthermore, a handle is installed on the outward side of the placement box close to the front column.

[0011] Furthermore, an identification plate is installed on the placement box, and the identification plate is next to the handle.

[0012] Furthermore, two isolation bars are provided in the placement box, and the two isolation bars divide the placement box into three placement cavities, and the placement cavities are used to place three concrete specimens.

[0013] Furthermore, the left support plate and the right support plate are both provided with a limiting snap-in at one end close to the front column, and a post is provided at the bottom of the placement box, and the limiting snap-in is adapted to the post.

[0014] Furthermore, the middle parts of the two side walls of the placement box are fixedly connected with balance boards, the upper ends of the two balance boards are provided with connection ports, and the two connection ports are connected with handles made of soft materials.

[0015] The beneficial effects of the present invention are that the concrete specimen storage device is set according to the specifications of standard concrete specimens, which can maximize the use of space. At the same time, when a higher concrete specimen needs to be placed, the concrete specimen is placed in the placement box. Because the entrance is not blocked by a beam and the top of the placement box is also an open structure, a higher concrete specimen can be placed in the storage device as a whole. At this time, only the two specimen boxes connected upper and lower are occupied, and the other areas can still be used to place standard concrete specimens normally. There is no need to arrange manual cooperation to increase the height of the bracket, which is labor-saving and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solution of the present invention is further elaborated in detail below in conjunction with the drawings and specific embodiments of the specification. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. In the following description, reference is made to "some embodiments", which describes a subset of all possible embodiments, but it should be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

[0024] Example 1

[0025] Combined with reference to Figures 1 to 5 The utility model provides a concrete specimen storage device, including a base plate 1 and a multi-layer specimen rack 25, the specimen rack 25 is fixed on the base plate 1, the specimen rack 25 includes a plurality of horizontally arranged specimen boxes 4, the specimen box 4 includes two front columns 2, two rear columns 3, a left support plate 6, a right support plate 7 and a placement box 5, the left support plate 6 is fixedly connected to the front column 2 and the rear column 3 on the left side, the right support plate 7 is fixedly connected to the front column 2 and the rear column 3 on the right side, the left support plate 6 and the right support plate 7 are horizontally arranged, the placement box 5 is used to place concrete specimens, and the placement box 5 is slidably connected to the left support plate 6 and the right support plate 7. There is no crossbeam blocking the front of the entire storage device. Each specimen box 4 is supported by two front columns 2 and two rear columns 3 to ensure the load-bearing capacity of the specimen box. Standard concrete specimens only need to be placed in the placement box 5 and stored normally in the specimen box. When placing higher non-standard concrete specimens, because there is no crossbeam blocking the front, the space between the left support plate 6 and the right support plate 7 of the upper layer is not blocked, and will not affect the higher concrete specimens below. It is only necessary to leave the affected specimen box 2 of the upper layer empty and not put in the placement box 5.

[0026] Preferably, an isolation plate 8 is connected between the left front column 2 and the rear column 3, between the right front column 2 and the rear column 3, and between the two rear columns 3. The isolation plate 8 can ensure that the box 5 placed in each test box 4 will not slide into the test box 4 next door, nor will it slide out from the rear.

[0027] Preferably, universal wheels 20 are installed at the four corners of the base plate 1, and a foot brake is installed on one side of the universal wheel 20. This facilitates the movement and transportation of the entire storage device, and the storage device can be easily transported to the maintenance room of the project without disassembly. When the project site is changed, it is also convenient to transport it to a new maintenance room.

[0028] Preferably, support structures 19 are mounted on all four edges of the base plate 2. Support structure 19 includes a connecting block 16, a knob 15, a threaded rod 14, and a support block 13. Connecting block 16 is fixedly connected to base plate 2. Connecting block 16 has a threaded hole 23, through which threaded rod 14 passes and is threadedly connected. Knob 15 is mounted at the upper end of threaded rod 14, and support block 13 is mounted at the lower end of threaded rod 14. Because concrete specimens are heavy, especially when a large number of concrete specimens are placed in the storage device, the weight of the entire storage device is significant. Relying solely on universal wheels 20 for support would reduce the safety of the entire device. With the addition of support structure 19, when the storage device needs to be moved, the support block 13 can be raised by rotating knob 15 without affecting the mobility of the storage device. When placing concrete specimens in the curing room, rotating knob 15 causes support block 13 to press against the ground, which relieves the pressure on universal wheels 20 and improves the safety of the entire storage device.

[0029] Preferably, the bottom of the placement box 5 is composed of cross-connected support bars 9. This increases the contact between the bottom of the concrete specimen and the moist air, ensures the normal curing of the concrete specimen in the curing room, and improves the strength of the entire concrete specimen.

[0030] Preferably, a handle 10 is installed on the outward side of the placement box 5 close to the front column 3. It is convenient to pull the placement box 5 out of the storage device.

[0031] Preferably, an identification plate 11 is installed on the placement box 5, and the identification plate 11 is next to the handle 10. The information of the concrete test piece placed in the placement box 5 is recorded on the identification plate, which is convenient for finding the test piece that has reached the curing period.

[0032] Preferably, two isolation strips 21 are provided within the placement box 5. The two isolation strips 21 divide the placement box 5 into three placement cavities, each used to hold three concrete specimens. The isolation strips 21 isolate the three concrete specimens within the placement box 5, preventing them from clumping together due to other factors, and ensuring that the concrete curing meets requirements.

[0033] Preferably, both the left support plate 6 and the right support plate 7 are provided with a limit stopper 17 at one end near the front column 3, and a clamping post 18 is provided at the bottom of the storage box 5, and the limit stopper 17 is adapted to the clamping post 18. The clamping post 18 and the limit stopper 17 ensure that the storage box 5 will not accidentally slide out from the front, thereby increasing the safety of the entire storage device. In addition, the entire storage device is relatively low. When it is necessary to pull out the storage box 5, the handle 10 is pulled at an upward angle to just lift the storage box 5 a little, and the storage box 5 can be pulled out smoothly.

[0034] Example 2

[0035] See attached Figure 6 This embodiment differs from the first embodiment in that a balance plate 22 is fixedly connected to the middle of each of the two side walls of the placement box 5. Each balance plate 22 has a connection port 24 at its upper end, connected to a handle 12 made of a soft material. Because the entire storage device is relatively low, placing the placement box 5 in or out of the specimen box 4 requires bending over and holding the placement box 5 with both hands, which is very uncomfortable. However, the addition of the handles 12 allows the operator to conveniently place the placement box 5 into the specimen box 4 at the bottom. The soft handles 12 ensure that the placement box 5 can be fully inserted into the specimen box 4 without obstruction. Furthermore, the placement box 5 can be used as a transport for concrete specimens. Newly prepared concrete specimens can be directly transported from the preparation room to the storage device in the curing room via the placement box 5, and then the entire placement box can be placed back into the storage device. This reduces the number of loading and unloading steps and increases the safety of the concrete specimens.

[0036] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. The scope of protection of the present invention should be based on the scope of protection of the claims.
