Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete sampling, in particular to a concrete compression test piece forming test mould. Background Art
[0002] In my country, concrete compressive strength is assessed using standard cubic test blocks (150mm x 150mm x 150mm). These blocks are formed using standard methods, cured under standard conditions, and tested using standard methods. As one of the most important performance indicators of structural concrete, compressive strength requires true, accurate, and reliable measurements. Failure to accurately measure concrete compressive strength in construction projects can hinder quality assurance and design compliance, potentially leading to economic losses and, in severe cases, structural safety concerns and serious accidents.
[0003] At present, concrete test molds are mainly divided into two categories, metal test molds and plastic test molds.
[0004] Due to its material properties, metal test molds are prone to rust. Failure to clean them thoroughly can result in non-compliant flatness. During assembly, uneven force distribution can create a parallelogram-shaped cross-section. Failure to install them tightly can lead to leakage. Furthermore, metal materials are heavy, requiring specialized skills from test personnel and creating certain inconveniences during handling.
[0005] Compared to traditional metal concrete molds, plastic molds are known for their light weight and lower cost. However, because they are integrally formed and non-detachable, they take up a lot of space during transportation and storage, making them inconvenient. Furthermore, plastic molds present challenges during demolding and are difficult to clean after demolding. Utility Model Content
[0006] The utility model provides a concrete compression test piece forming mold, aiming to solve at least one technical problem existing in the prior art mentioned in the background technology.
[0007] The present invention provides the following technical solutions to achieve the above objectives:
[0008] A test mold for forming a concrete compression test piece includes a test mold. The test mold has dimensions of 160 mm in length, 160 mm in width, and 170 mm in height. The inner cavity volume of the test mold is 150 mm × 150 mm × 150 mm. The side wall thickness of the test mold is 5 mm, and the bottom thickness is 20 mm. The test mold includes a front half test mold and a rear half test mold. A plurality of openings are opened at the bottom of the front half test mold. An insertion rod matching the openings is provided at the bottom of the rear half test mold. A hoop is provided around the front half test mold and the rear half test mold. The hoop includes two symmetrically arranged semi-rectangular hoop rings.
[0009] Furthermore, the dimensions of the front half test mold and the rear half test mold are 160 mm in length, 80 mm in width and 170 mm in height.
[0010] Furthermore, the two symmetrically arranged semi-rectangular hoops are connected by bolts.
[0011] Furthermore, two openings are provided at the bottom of the front half of the test mold, with an opening area of 30 mm×10 mm and a hole depth of 40 mm.
[0012] Furthermore, the material of the front half test mold and the back half test mold is ABS plastic.
[0013] Furthermore, the semi-rectangular hoop is made of stainless steel, and the cross-sectional dimensions of the semi-rectangular hoop are 3 mm thick and 20 mm high.
[0014] Beneficial effects
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] The utility model has a simple structure and can significantly shorten the time of assembly and disassembly. When not in use or for transportation, the utility model can be disassembled into different parts and components, which is convenient for transportation and reduces the space occupied. At the same time, if a part or component is damaged, it can be replaced with the corresponding part in time, saving time and cost.

[0025] Example. A concrete compression test piece forming mold, the structure of which is referenced Figures 1 to 3, including a test mold, the dimensions of the test mold are 160mm long, 160mm wide, and 170mm high. The inner cavity volume of the test mold is 150mm×150mm×150mm, the side wall thickness of the test mold is 5mm, and the bottom thickness is 20mm. The test mold includes a front half test mold 1 and a back half test mold 2. The bottom of the front half test mold 1 is provided with a plurality of openings, and the bottom of the back half test mold 2 is provided with a plug 5 that matches the openings. A hoop 3 is provided around the front half test mold 1 and the back half test mold 2, and the hoop 3 includes two symmetrically arranged semi-rectangular hoops. The dimensions of the front half test mold 1 and the back half test mold 2 are 160mm long, 80mm wide, and 170mm high. The bottom of the front half test mold 1 is provided with two openings, the opening area is 30mm×10mm, and the hole depth is 40mm. By dividing the test mold with dimensions of 160 mm in length, 160 mm in width and 170 mm in height into a front half test mold 1 and a rear half test mold 2 with dimensions of 160 mm in length, 80 mm in width and 170 mm in height, the space occupied by the test mold is reduced, and the transportation and storage of the test mold are facilitated; by providing a plurality of openings at the bottom of the front half test mold 1 and providing a plug rod 5 matching the openings at the bottom of the rear half test mold 2, it is convenient to assemble the front half test mold 1 and the rear half test mold 2 to form a complete test mold. Compared with the traditional metal concrete test mold, the difficulty of use is reduced and it is more convenient for the production of concrete compression test pieces.
[0026] The material of the front half test mold 1 and the back half test mold 2 is ABS. The two symmetrically arranged semi-rectangular hoops are connected by bolts 4. The two symmetrical semi-rectangular hoops are connected and fixed to the test mold by M10 bolts. The material of the semi-rectangular hoops is stainless steel, and the cross-sectional dimensions of the semi-rectangular hoops are 3 mm thick and 20 mm high. By using ABS as the material of the test mold, the strength characteristics and chemical stability of ABS itself are fully utilized, and the production cost of the test mold is reduced compared to the traditional metal concrete test mold; by setting the hoop 3 as two symmetrical semi-rectangular hoops and connecting them by M10 bolts, the tightness of the connection between the front half test mold 1 and the back half test mold 2 is improved, and the tightening method using the hoop 3 is simpler and more convenient to operate.
[0027] The method of using the present invention is as follows: when a concrete compression test piece needs to be made, the front half test mold 1 and the rear half test mold 2 are first cleaned. After cleaning, the front half test mold 1 and the rear half test mold 2 are matched and inserted into the hole and the insertion rod 5 to form a complete test mold. Then, two symmetrical semi-rectangular hoops are placed around the complete test mold and fixedly connected by bolts 4 to ensure the connection strength and airtightness of the test mold. Then, a release agent is applied to the inside of the test mold, and the production of the concrete compression test piece can be started.
