Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, and particularly relates to a layered concrete test block mold. Background Art

[0002] Standard test blocks are important references for detecting the quality of concrete. Existing plastic test molds and steel test molds are used to make conventional concrete test blocks according to relevant standards, but they are not applicable to some new unconventional concrete materials. The Chinese invention patent application with the publication number CN116950299A discloses a precast thermal insulation floor slab and its production method, in which a polystyrene particle concrete material is used, which can be controllably layered during the vibration process to form a structural stress part and a thermal insulation part inside the material. This material is unconventional, and there is currently no special test block mold that can meet the requirements for detecting the performance of each part after layering. Content of the Utility Model

[0003] The purpose of the utility model is to provide a mold for making standard test blocks of concrete materials with artificially controllable layering in view of the deficiencies in the above background art. The test blocks made by the mold meet the requirements of relevant specifications and can be used for detection items such as compressive strength, softening coefficient, and unit weight.

[0004] To achieve the above purpose, the utility model provides a layered concrete test block mold, which includes a base, a cover plate, a partition insertion plate, and a caulking plate. The base and the cover plate enclose a cavity for pouring concrete.

[0005] An opening is provided on the cover plate, and the opening matches the sizes of the partition insertion plate and the caulking plate. The caulking plate is used to fill the opening, and the partition insertion plate is used to insert from the opening to the opposite side wall of the cavity to divide the cavity, so as to form a partition before the concrete test block in the cavity begins to set.

[0006] Further, the base includes a bottom plate and a surrounding plate. Three surrounding plates are provided to form a three-sided surrounding form. The cover plate and the surrounding plate form the cavity, and the top of the cavity is open.

[0008] Further, strip-shaped grooves are provided on the lower surface of the bottom plate.

[0009] Further, bolt holes are provided at corresponding positions on the cover plate and the surrounding plate, and the cover plate and the surrounding plate are detachably connected by bolts.

[0010] Further, vertical ribs and horizontal ribs are provided on the cover plate. The horizontal ribs are distributed above the opening, and the vertical ribs are distributed below the opening. Protrusions are provided on both sides of the opening to assist the partition insertion plate or the caulking plate to maintain horizontal and stable during the process of inserting into the opening.

[0011] Further, the length of the partition insertion plate is equal to or exceeds the depth of the cavity + the thickness of the cover plate + the depth of the vertical rib or the horizontal rib, and the length of the caulking plate is equal to or exceeds the thickness of the cover plate + the depth of the vertical rib or the horizontal rib.

[0012] Further, the caulking plate is provided with limit blocks.

Detailed implementation manner

[0024] To make the technical problems, technical solutions and advantages to be solved by the present utility model clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without creative work belong to the protection scope of the present utility model. In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0026] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a locking connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0027] As Figures 1 - 4 shown, the embodiment of the present utility model provides a layered concrete test block mold, including a base 10, a cover plate 20, a partition insert plate 30 and a caulking plate 40. Among them, the base 10 is composed of a bottom plate 11 and an integral structure of enclosure plates 12 on three sides. Enclosure ribs 13 are provided on the enclosure plates 12. Preferably, the enclosure ribs 13 are distributed vertically to improve the overall stiffness. A strip groove 14 is provided on the lower surface of the bottom plate 11 to reduce weight and increase stiffness through the strip groove 14. In addition, it can adapt to the uneven ground conditions.

[0028] The cover plate 20 is used to be installed on the fourth side that is vacant relative to the three-sided enclosing plate 12. Bolt holes 50 are provided at the edges of the cover plate 20 and the edges of the enclosing plate 12 (or the enclosing rib plate 13). The cover plate 20 is fixed to the base 10 by bolts and can be easily disassembled when disassembly is required. After the cover plate 20 and the base 10 are assembled, a cavity with a size of 100*100*205 mm (taking this size as an example) is formed, and the top is open. Among them, the thicknesses of both the cover plate 20 and the enclosing plate 12 are set to 5 mm. Similarly, vertical rib plates 21 and horizontal rib plates 22 are also provided on the cover plate 20 to increase the stiffness.

[0029] In this embodiment, in the middle of the cover plate 20, that is, at the 100 mm height position of the cavity, an opening 23 with a size of 100 mm * 5 mm is provided. Among them, there is a horizontal rib plate 22 above the opening 23, one or more vertical rib plates 21 below it, and a convex block 24 is provided on each side of the opening 23. Through the horizontal rib plate 22 above the opening 23, the vertical rib plates 21 below it, and the convex blocks 24 on both sides, it can assist in separating the insertion plate 30 or the caulking plate 40 to keep horizontal and stable during the process of inserting into the opening 23.

[0030] In this embodiment, the widths of both the separating insertion plate 30 and the caulking plate 40 are 100 mm, and the thicknesses are both 5 mm. The length of the separating insertion plate 30 is 135 - 200 mm (equal to or exceeding the depth of the 100 mm cavity + 5 mm wall thickness + 30 mm rib plate depth), and the length of the caulking plate 40 is 35 - 100 mm (equal to or exceeding the 5 mm wall thickness + 30 mm rib plate depth). A limit block 41 is provided on the side of the caulking plate 40 close to the cavity after installation to ensure that the caulking plate 40 is flush with the inner wall of the cavity after being inserted into the opening 23 of the cover plate 20 and cannot be further inserted into the cavity.

[0031] At the same time, as Figure 5 shown, the function of the caulking plate 40 is to fill the opening 23 so that the concrete poured into the cavity will not flow out from the opening 23. The function of the separating insertion plate 30 is to be inserted into the opening 23 and separate the concrete in the cavity, and the separation is carried out before the concrete initial setting to obtain two test blocks with different properties after stratification.

[0032] It should be noted that the setting of the above dimensions is only an example in this embodiment, rather than a limitation on the dimensions of the layered concrete test block mold. Those skilled in the art can flexibly select based on the actual test block production requirements. In addition, multiple openings 23 can also be provided on the cover plate 20, and the vertical rib plates 21, horizontal rib plates 22, convex blocks 24, etc. are correspondingly arranged, and the numbers of the separating insertion plate 30 and the caulking plate 40 are correspondingly arranged to obtain more different test blocks by stratification.

[0033] When making the test block, assemble the base 10 and the cover plate 20, insert the caulking plate 40 into the opening 23 of the cover plate 20, apply the release agent, and complete the pouring preparation. Then pour the layered concrete into the cavity until it is filled, place it on a vibration table to vibrate the layers, and after the layers are stable, pull out the caulking plate 40, insert the partition plug 30 into the opening 23 and separate the concrete until it hits the inner wall of the cavity on the opposite side, wipe off the concrete material overflowing from the top, and let it stand for more than 24 hours before demolding. For demolding, first remove the bolts of the base 10 and the cover plate 20, and take out the cover plate 20. Then remove the partition plug 30, leaving two 100*100*100mm test blocks in the cavity, and then pour the test blocks out of the cavity to obtain two test blocks, one heavy and one light, after layering.

[0034] Therefore, when the layered concrete test block mold provided by this embodiment is used to make concrete test blocks, the test blocks made can objectively reflect the performance of each layer, realize the separate analysis and research of the material performance of each layer, and are targeted. During production, the test blocks are separated by the partitioning plug 30 before the initial setting of the concrete, instead of cutting after demoulding, so that there is no error caused by removing materials, so that the test blocks can more realistically reflect the material performance, and the trouble of cutting and the cost of using high-power cutting equipment are saved.

[0035] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
