Description

Technical Field

[0001] This application relates to the technical field of concrete quality inspection, and particularly to a concrete test block mold. Background Art

[0002] In the construction industry, it is necessary to make concrete test blocks for quality inspection and sample retention. Among them, in national and industry standards, there are strict requirements for the external dimensions of concrete test blocks. Therefore, special molds are required to pour concrete test blocks. For example, a kind of integral concrete test block mold disclosed in Chinese Patent with the application number CN00205273.3. When in use, pour concrete into the mold, vibrate and level it. After the concrete solidifies, blow high-pressure air into the air holes at the bottom of the mold to separate the concrete test block from the mold to obtain the required concrete test block. In the actual use process, the concrete will leak out from the air holes before solidification, resulting in protrusions on the side of the concrete test block; secondly, when making concrete test blocks, in order to prevent substitution, tags are usually embedded in the test blocks. However, in actual operation, it is difficult to grasp the embedding depth of the tags. If the tags are embedded too deep, the concrete will cover the tags, resulting in the tags being unrecognizable, while if the embedding depth of the tags is insufficient, the tags are prone to protrude, affecting the surface quality of the concrete test block.

[0023] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. Obviously, the described embodiments are only a 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 of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0025] In addition, the descriptions involving "first", "second", etc. in the present application are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of the said features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0026] As Figures 1 to 7 shown, an embodiment of the present utility model provides a concrete test block mold, including: a box body 1 and a label 2. The box body 1 is of a cuboid structure. There is an opening at the upper part of the box body 1. The inner cavity of the box body 1 is divided into a plurality of forming cavities 4 by a plurality of partition plates 3; a positioning ring 5 is provided at the bottom of the forming cavity 4, and an air hole 6 is provided at the central position of the positioning ring 5, and the air hole 6 penetrates through the bottom of the box body 1; a circular groove 7 is provided on one side of the label 2, the label 2 is buckled and pasted on the bottom of the forming cavity 4, the label 2 covers the outside of the positioning ring 5 and the circular groove 7 is connected to the positioning ring 5.

[0027] Before making the concrete test block, tear off the isolation paper on the label 2, and then buckle and paste it on the bottom of the forming cavity 4. At this time, the circular groove 7 is limited by the positioning ring 5. At the same time, after the label 2 is pasted on the bottom, when pouring concrete, it can prevent the unhardened concrete from flowing out of the box body 1 through the air hole 6. At the same time, because the label 2 is pasted on the bottom of the forming cavity 4, after the concrete test block is poured and solidified, the end face of the label 2 is flush with the concrete test block, ensuring the flatness of the side of the concrete test block while avoiding contaminating the label 2 with concrete and ensuring the identifiability of the label 2.

[0028] When making a concrete test block, pour the concrete to be tested into the forming cavity 4. When it is half filled, vibrate it, then continue to fill it up and vibrate it again. Then, use a tool to scrape the concrete on the upper part of the box body 1 flat. After the concrete solidifies, turn the box body 1 over, and then pass compressed air into the air holes 6 through an air gun. Under the action of the compressed air, the side wall of the box body 1 expands, so that the label 2 and the concrete test block are separated from the inner wall of the box body 1, facilitating the removal of the concrete test block from the forming cavity 4.

[0029] Preferably, as Figure 1 shown, there are multiple vertical ribs 8 on the outside of the box body 1, which improves the anti-deformation performance of the box body 1, so as to ensure that the external dimensions of the concrete test block meet the requirements when pouring the concrete test block.

[0030] Specifically, as Figure 3 、 Figure 7 shown, there is a connecting strip 9 on the rib 8, and multiple box bodies 1 are connected to each other through the connecting strip 9. After multiple box bodies 1 are joined, when pouring concrete, multiple box bodies 1 can be quickly filled, improving the production speed of the concrete test block.

[0031] Preferably, as Figure 5 shown, there are multiple embedding strips 10 on the label 2, and barbs 11 are provided at the ends of the embedding strips 10. The label 2 is embedded in the concrete test block, and the embedding strips 10 and barbs 11 can prevent the label 2 from falling off the test block.

[0032] In a specific embodiment, the label 2 is provided with a double-sided adhesive layer at the edge of the circular groove 7, and the circular groove 7 is connected to the bottom of the forming cavity 4 through the double-sided adhesive layer. When pouring concrete, the label 2 is adhered to the bottom of the forming cavity 4 through the double-sided adhesive layer, achieving the effect of preventing concrete leakage.

[0033] Preferably, a two-dimensional code is set at the bottom of the circular groove 7. During detection, the tester can obtain information about the concrete test block, such as batch number, production time, etc., by scanning the two-dimensional code. There is a signature area on the back of the label 2, and relevant personnel sign their names during production. After the label 2 is embedded in the concrete test block, it can achieve the purpose of preventing substitution, thus ensuring the authenticity of the test data.

[0034] In a preferred embodiment, there are 2 to 3 forming cavities 4 in each box body 1, and the upper end face of the box body 1 is flat, so as to quickly complete the pouring of multiple concrete test blocks and quickly scrape the concrete on the upper part of the box body 1 flat by tools such as a scraper.

[0035] In a specific embodiment, the box body 1 is made of plastic, and the box body 1 and the partition 3 are of an integral structure. The plastic can undergo a certain deformation. When compressed air is passed into the air holes 6 through an air gun, the side wall of the box body 1 expands under the action of the air pressure, separating the inner wall of the box body 1 from the side of the concrete test block, facilitating demolding.

[0036] Specifically, the molding cavity 4 is in the shape of a cube with a side length of 100 mm or 150 mm, so that the formed concrete test block meets the requirements of national standards or industry standards for the external dimensions of the test block.

[0037] Of course, there can be many other implementation manners of the present application. Based on this implementation manner, other implementation manners obtained by those of ordinary skill in the art without any creative work belong to the scope protected by the present application.
