Technical Field

[0001] The utility model relates to the field of concrete moulds, in particular to a low-shrinkage self-leveling concrete mould. Background Art

[0002] Low shrinkage self-leveling concrete is a special self-leveling material. Its main feature is its low shrinkage rate during the curing process. This material can automatically flow to fill the depressions and unevenness on the ground during construction, but shrinks less after curing, thereby reducing the risk of cracking and deformation of the ground.

[0003] The existing technology has the following problems:

[0004] The existing mold is an integrated structure. After the low-shrinkage self-leveling concrete is poured, the casting needs to be taken out of the mold cavity. During the demolding process, the integrated cavity has a large contact surface with the cavity, so there is a problem of damage to the casting due to adhesion, which affects the molding quality of the casting.

[0023] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0024] like Figure 1-3As shown, the low shrinkage self-leveling concrete mold proposed by the present invention includes a basic mold base 1 and an expansion mold base 2 stacked on the basic mold base 1. The bottom of the basic mold base 1 is a closed structure, and the expansion mold base 2 is a top-to-bottom through structure. The overall inner cavity of the combination of the two is a cavity for pouring low shrinkage self-leveling concrete;

[0025] The assembly mechanism includes a positioning platform 31 set at the edge of the basic mold platform 1 and the expansion mold platform 2. A positioning rod 32 runs through the positioning platform 31. A slot 33 is formed on the upper part of the expansion mold platform 2, and a raised insert plate 34 is formed on the lower part. The adjacent expansion mold platforms 2 and the basic mold platform 1 are fixed by inserting and fixing them together through the insert plate 34 and the slot 33.

[0026] The transfer structure includes a transfer frame 41 provided on the side walls of the basic mold platform 1 and the extended mold platform 2. A vertical plate 42 is provided on one side of the transfer frame 41. A transfer plate 43 is formed on the vertical plate 42 and penetrates the inner cavity of the transfer frame 41. The transfer plate 43 and the transfer frame 41 are screwed and fixed by a locking bolt 44.

[0027] A vibration motor 5 is mounted on the other side wall of the vertical plate 42 .

[0028] It should be noted that: at least one vibration motor 5 is installed on the vertical plate 42. In this application, there are two vibration motors 5, which are respectively arranged at the bottom of the combination of the basic mold platform 1 and the extended mold platform 2. Since the lower layer cavity of the mold platform after the combination is vibrated, it can drive the low-shrinkage self-leveling concrete to slide down and compact under the action of gravity, expel residual bubbles, and improve the molding quality.

[0029] It should be added that: when the number of expansion mold platforms 2 is large, a vibration motor can be added to the side vertical plate 42 thereof to increase the number of vibration points and thus improve the molding quality.

[0030] In this embodiment, before pouring low-shrinkage self-leveling concrete, the basic formwork platform 1 and the extended formwork platform 2 are combined by the combination mechanism, the insert plate 34 is inserted into the slot, and then the positioning rods 32 are respectively pressed into the positioning holes opened in the positioning platform 31 to complete the internal combination. Subsequently, external reinforcement is performed by the adapter mechanism, and the adapter plates 43 on the vertical plates 42 are respectively inserted into the inner cavity of the adapter frame 41. The locking bolts 44 are screwed into the screw holes between the adapter plates 43 and the adapter frame 41 to complete the external reinforcement. The low-shrinkage self-leveling concrete in the cavity is vibrated and compacted by the external vibration motor 5.

[0031] When the molded casting needs to be taken out, the combination mechanism and the transfer mechanism can be disassembled layer by layer, and the expansion mold base 2 and the basic mold base 1 can be removed layer by layer from top to bottom, which solves the problem that the traditional mold has too many contact surfaces with the casting and is easily damaged when taking out the part.

[0032] In order to improve the connection tightness between the plug-in board 34 and the slot 33, the plug-in board 34 is further configured as a "U-shaped" structure, and the slot 33 that cooperates therewith is configured as a matching structure.

[0033] In order to facilitate the positioning between the basic mold platform 1 and the extended mold platform 2 , the positioning platform 31 further protrudes from the corners of the basic mold platform 1 and the extended mold platform 2 , and a through positioning hole is opened in the middle.

[0034] In one embodiment, a raised convex plate 45 is symmetrically formed on the vertical plate 42, and a spring member 46 is installed on the end surface of the convex plate 45 facing the basic mold platform 1 and the extended mold platform 2. When the vibration of the vibration motor 5 acts on the side walls of the extended mold platform 2 and the basic mold platform 1, the deformation of the spring member 46 is used to buffer and prevent excessive vibration.

[0035] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention. In addition, the appended claims of the present invention are intended to cover all variations and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents thereof.
