AI Technical Summary
目前,使用最多的模具是由底板和立板固结为一个整体而形成的,且多为塑料材质,由于模具作为整体不可拆卸,使得试块成型后脱膜比较困难,通常采用敲打模具的方法将混凝土试块取出,但是这种做法容易导致试块损坏和模具本身损坏,而且还降低了工作效率
[0008]本实用新型的优点是:第一,该模具组装和拆卸方便,提高了混凝土浇筑效率。这种可拆卸式混凝土模具,通过底座和插板相拼接的方式,快速完成了模具的组装。第二,振动过程不漏浆,提高混凝土试块质量。该模具通过凹凸槽拼接,连接部位牢固可靠,从而有效避免了混凝土在浇筑和振动时出现漏浆现象,减少浆液流失,保证了混凝土试块的配合比准确,提高了试块的质量。第三,易于混凝土试块脱模。在完成模具的组装后,在模具内表面涂上一层脱模剂,待混凝土试块终凝成型后,轻推侧板框架与底座拆卸分离,便可取出混凝土试块。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete testing technology, and in particular to an easy-to-demold concrete test block mold. Background Technology
[0002] In concrete testing, standard concrete test blocks are frequently used to test concrete strength, and the molding of these test blocks requires molds. Currently, the most commonly used molds consist of a base plate and a vertical plate fixed as a single unit, and are mostly made of plastic. Because the mold is a single, non-removable unit, removing the test block after molding is difficult. The common method is to tap the mold to remove the concrete test block, but this approach easily damages both the test block and the mold itself, and also reduces work efficiency. Utility Model Content
[0003] The purpose of this utility model is to solve the problems of the prior art mentioned above and to provide an easy-to-demold concrete test block mold, wherein the side plate frame and the base can be disassembled and separated after the concrete test block is formed, making it easy to demold the concrete test block without vibration or knocking. The material is lightweight, easy to assemble, and safe to use.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A concrete test block mold that is easy to demold includes a base and a side plate frame with a size no larger than the base. The base includes multiple concave slots, and the side plate frame includes cavities formed by multiple side plates and multiple convex slots connected to the bottom of the side plate frame. The convex slots and concave slots are tightly inserted and fitted together. After connection, each cavity is located above the portion of the base without concave slots, forming a sealed mold cavity with the base. Limiters are connected to both sides of the bottom of the side plate frame, and the limiters are fixedly connected to the base through fasteners.
[0005] The limiter is fixedly connected to the base by bolts.
[0006] The mold cavity consists of three cubic cavities with a side length of 150mm. There are four convex slots and four concave slots. The convex slots are integrally formed with the side plate frame.
[0007] Both the side panel frame and the base are made of plastic.
[0008] The advantages of this invention are: First, the mold is easy to assemble and disassemble, improving concrete pouring efficiency. This detachable concrete mold is assembled quickly by splicing the base and insert plates. Second, it prevents grout leakage during vibration, improving the quality of concrete test blocks. The mold uses a tongue-and-groove splicing system, ensuring a firm and reliable connection, effectively preventing grout leakage during pouring and vibration, reducing grout loss, ensuring accurate mix proportions for the concrete test blocks, and improving the quality of the test blocks. Third, it facilitates demolding of concrete test blocks. After assembling the mold, a release agent is applied to the inner surface. Once the concrete test block has fully set, the side frame can be gently pushed to separate from the base, allowing the concrete test block to be removed.
[0009] This utility model features a novel splicing method that facilitates pouring and demolding without the need for vibration demolding. Compared to conventional methods, this mold avoids the risk of cracks inside the concrete specimen caused by striking the mold side plate when removing the specimen, thus improving demolding efficiency and the accuracy of the concrete specimens used for mechanical testing.

Detailed Implementation
[0011] The present invention will be further described below with reference to the accompanying drawings, but the present invention is not limited to the specific embodiments.
[0012] Example 1
[0013] like Figures 1-4 As shown, an easy-to-demold concrete test block mold includes a base 1 and a side plate frame 2 with a size no larger than the base. The base 1 includes multiple concave slots 101. The side plate frame 2 includes cavities formed by multiple side plates and multiple convex slots 201 connected to the bottom of the side plate frame 2. The convex slots 201 are tightly inserted into the concave slots 101. After connection, each cavity is located above the non-concave slot portion of the base 1, forming a sealed mold cavity with the base 1. Limiters 3 are connected to both sides of the bottom of the side plate frame 2. The limiters 3 are fixedly connected to the base 1 by bolts 301.
[0014] In this embodiment, the mold cavity is three cubic cavities with a side length of 150mm, and there are four convex slots 201 and four concave slots 101. The convex slots 201 are integrally formed with the side plate frame 2.
[0015] Both the side frame 2 and the base 1 are made of plastic.
[0016] Example 2
[0017] In practical use, this utility model has the following steps: Step 1: Before assembly, clean the base 1 and side frame 2 of the mold thoroughly, especially the concave slot 101, which should be free of sand, gravel, and other debris.
[0018] Step 2: Connect the side frame 2 and the base 1 by inserting them into each other through four sets of slots. Install the limit bolt 301 at the limiter 3 for fixation and check the tightness of the mold.
[0019] Step 3: Apply release agent to the inner surface of the assembled mold cavity.
[0020] Step 4: Pour the concrete into the mold cavity and then place it on a vibrating table for compaction.
[0021] Step 5: After the concrete has fully set, release the limiting bolt 301 of the limiter 3, push the side frame 2 to the side and remove it from the base 1.
[0022] Step 6: Push the concrete test block from above and lift the side frame 2 to separate the concrete test block from the frame.
[0023] Step 5: Clean the mold, assemble it properly, and store it for future use.
[0024] Although the above embodiments have described the concept and embodiments of the present invention in detail with reference to the accompanying drawings, those skilled in the art will recognize that various improvements and modifications can still be made to the present invention without departing from the scope of the claims, and therefore will not be elaborated here.
