Description

Technical Field

[0001] The utility model relates to the field of construction tools, in particular to a detachable mould for a concrete test block. Background Art

[0002] A concrete test block is a standardized specimen, usually made by mixing water, cement, fine sand, and coarse aggregate in specific proportions and pouring it into a specific mold. Since it is difficult to directly test the strength of concrete during the construction process, the preparation and testing of concrete test blocks have become an important means of evaluating the quality and reliability of concrete.

[0003] Currently, plastic molds are most commonly used for making concrete test blocks. However, this type of mold has the following problems: the plastic mold as a whole cannot be disassembled, making it difficult to demold the test block after molding. In addition, during the demolding process, the mold is usually knocked to assist in removing the concrete test block, which can easily lead to damage to the test block and the mold itself.

[0004] Therefore, it is urgent to provide a detachable mould for concrete test blocks. Summary of the Invention

[0005] In order to overcome the shortcomings of traditional plastic molds, which are not removable as a whole, making subsequent demoulding of the test blocks difficult and easily damaging the test blocks, the technical problem to be solved is to provide a removable mold for concrete test blocks.

[0006] In order to solve the above problems, the utility model adopts the following technical solutions: a detachable mold for a concrete test block, comprising a bottom template, four side templates, lateral screw buckles, forward screw buckles and fixing bolts. The four side templates are respectively vertically installed on the four sides of the bottom template to form a cubic mold together. The side walls of each side template are provided with symmetrically distributed lateral screw buckles, and the outer walls of each side template are provided with symmetrically distributed forward screw buckles. The four side templates are connected to each other by screwing fixing bolts between the lateral screw buckles and the adjacent forward screw buckles to form a complete detachable mold.

DETAILED DESCRIPTION

[0020] First of all, it should be noted that in the various described embodiments, identical components are provided with identical reference numerals or identical component names, wherein the disclosure contained throughout the entire description can be transferred to the same components having the same reference numerals or identical component names. Positional designations selected in the description, such as top, bottom, lateral, etc., also refer to the directly described and illustrated figures and are transferred to the new position in the event of a change in position.

[0021] Example 1: Please refer to Figure 1 and Figure 2 , a detachable mold for a concrete test block includes a bottom template 1, four side templates 2, lateral turnbuckles 3, positive turnbuckles 4, fixing bolts 5 and dust covers 6. The four side templates 2 are respectively installed vertically on the four sides of the bottom template 1 to form a cubic mold. The side walls of each of the side templates 2 are welded with lateral turnbuckles 3 and positive turnbuckles 4 that are symmetrically distributed up and down, and each lateral turnbuckle 3 matches the positive turnbuckle 4 on an adjacent side template 2. The four side templates 2 can be connected to each other by screwing the fixing bolts 5 between the lateral turnbuckles 3 and the adjacent positive turnbuckles 4 to form a complete detachable mold. The dust cover 6 is arranged on the top of the constructed cubic mold to prevent dust and impurities from entering the mold, ensuring that the concrete test block is not contaminated by the outside world during the hardening process, thereby ensuring the quality of the test block.

[0022] Before pouring the concrete test block, the mold needs to be assembled first. First, the four side formworks 2 are connected end to end in sequence and installed vertically on the four sides of the bottom formwork 1 to ensure that the side formwork 2 fits tightly with the bottom formwork 1. Then, the fixing bolts 5 are screwed into the lateral turnbuckles 3 in sequence and docked with the adjacent forward turnbuckles 4 to fix the four side formworks 2 together. After completing the assembly of the mold, pour the evenly mixed concrete into the mold and ensure that the concrete fills the entire mold space to avoid gaps. After the concrete test block hardens and needs to be demolded, just turn the fixing bolts 5 to unscrew it from between the lateral turnbuckles 3 and the forward turnbuckles 4. After unscrewing the fixing bolts 5, the side formwork 2 can be easily removed, thereby realizing easy removal of the concrete test block without damaging the test block. This design makes the demolding process simpler, reduces the risk of test block damage, and improves demolding efficiency.

[0023] Example 2: Based on Example 1, please refer to Figure 2 and Figure 5 The bottom of the bottom template 1 is provided with a support seat 7 by fixing screws 10. The support seat 7 serves as the supporting base of the entire mold, which can effectively support the bottom template 1 and the side template 2, making the structural connection between them tighter. The four lateral directions of the support seat 7 are provided with guide grooves 8 for guiding the side template 2, which are used to guide when the side template 2 is installed. The four side templates 2 can be slid into and installed along the guide grooves 8 on the support seat 7 in turn, which greatly saves assembly time. The end of each guide groove 8 is provided with a limit rod 9 for limiting the maximum movement range of the side template 2. When the side template 2 moves, its side contacts the limit rod 9, which indicates that the side template 2 has reached the correct position. The height limiting block 11 is arranged at the top of the limit rod 9 for limiting the height of the side template 2, ensuring that the side template 2 will not exceed the predetermined height range during use, thereby ensuring the stability of the mold and the safety of operation.

[0024] See also Figure 3 , further comprising a fixing plate 12, a clamping rod 13 and a limiting plate 14. The side wall of the side formwork 2 is provided with a fixing plate 12 parallel to the side formwork 2, and the clamping rod 13 is welded to the fixing plate 12. The outer wall of the side formwork 2 is provided with a limiting plate 14 perpendicular to the side formwork 2, and the limiting plate 14 is provided with a hole matching the clamping rod 13. The fixing plate 12 is parallel to the limiting plate 14 on the adjacent side formwork 2. When assembling the mold, first align the fixing plates 12 on the left and right side formworks 2 with the limiting plates 14 on the front and rear side formworks 2, so that the clamping rod 13 passes through the hole of the limiting plate 14 to achieve a preliminary limiting connection effect. This ensures that the four side formworks 2 are accurately positioned during assembly, facilitating the subsequent installation of the fixing bolts 5.

[0025] See also Figure 4 and Figure 6 , also includes a top plate 15, a guide rod 16 and an adjusting screw 17. The top plate 15 is arranged at the top of the bottom template 1 and is used to lift the concrete test block during demoulding. The bottom of the top plate 15 is provided with guide rods 16 symmetrically distributed on the left and right. The guide rods 16 pass through to provide a guide for the top plate 15 to ensure that the top plate 15 remains horizontal during movement. An adjusting screw 17 is rotatably provided at the center position of the bottom of the top plate 15. The lower end thread of the adjusting screw 17 passes through the bottom template 1 and is used to adjust the height of the top plate 15. By rotating the adjusting screw 17, the top plate 15 is pushed upward. The top plate 15 moves horizontally under the guidance of the guide rods 16, lifting the concrete test block, so that the concrete test block can be separated from the bottom template 1 smoothly and quickly, thereby improving the demoulding efficiency and construction efficiency.
