Description

Technical Field

[0001] This utility model relates to the field of concrete mold technology, specifically to ultra-high performance concrete casting mold. Background Technology

[0002] In the field of building and infrastructure construction, ultra-high performance concrete (UHPC) is receiving increasing attention due to its superior mechanical properties and durability. However, existing concrete casting molds have some technical problems in production and application, which limit the full realization of UHPC's performance.

[0003] Existing concrete casting molds are mostly integrated, resulting in strong adhesion between the mold and the concrete. This makes the demolding process time-consuming and labor-intensive, sometimes requiring mechanical assistance. This not only increases the difficulty of construction but may also damage the concrete surface, affecting its integrity and aesthetics. During the concrete pouring process, due to the complex internal structure of the mold, air bubbles in the concrete are difficult to completely escape, resulting in a large number of air bubbles inside the cast concrete. These air bubbles reduce the density and mechanical properties of the concrete. In particular, in ultra-high performance concrete, the presence of air bubbles can seriously affect its durability and strength.

[0004] Therefore, an ultra-high performance concrete casting mold is needed to improve the above problems. Utility Model Content

[0011] As a preferred embodiment of this utility model, the air bubble removal structure includes an installation end fixedly connected to the lower end face of the upper cover. The lower end face of the installation end is provided with a plurality of air bladders, and the plurality of air bladders are connected to each other through a connecting pipe. The upper end of the upper cover is provided with an inflation end, and the inflation end is engaged with one end of the connecting pipe.

[0012] As a preferred embodiment of this utility model, the upper end of the cover is provided with several vent holes.

[0013] As a preferred embodiment of this utility model, the positioning mechanism includes positioning posts fixedly connected to the lower end face of the upper cover around the perimeter, positioning grooves that mate with the lower end of the positioning posts are provided around the upper end face of the base plate, and a protruding end is fixedly connected to the lower end face of the upper cover, the protruding end mates with the upper end of the forming frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The lower mold of this utility model can be quickly disassembled and installed. After the concrete is poured and formed, it can be easily demolded. The rubber inner layer facilitates the quick demolding of the molded part. At the same time, the air bubble removal structure can apply pressure during pouring to squeeze out the air bubbles inside the concrete, thus avoiding the presence of too many air bubbles inside the molded concrete.

[0026] Please see Figure 1-5 This utility model provides a technical solution:

[0027] For an example, please refer to...

[0028] The molding frame is used for adding concrete. After the concrete is added, the upper mold and the lower mold are matched and connected. The connection is made by a positioning mechanism. After the connection, the air pump connected to the air bubble degassing structure expands and applies pressure to the added concrete, squeezing out the air bubbles inside the concrete and preventing excessive air bubbles from remaining inside.

[0029] Please refer to Figure 1 , 2 3, 4, and 5, the molding frame includes a set of symmetrically arranged side plates a10, and side plates b11 are mated and connected between the ends of the two side plates a10. A casting space is formed between the side plates a10 and the side plates b11. A rubber inner layer 9 is provided in the casting space. Insertion holes 12 are provided at the joints of the ends of the two side plates a10 and the side plates b11. Positioning rods 13 are provided at the ends of the two side plates a10. Several support blocks 6 are fixedly connected to the bottom of each side plate a10 and the side plate b11. A limit frame 5 is provided at the upper end of the several support blocks 6. The limit frame 5 is sleeved on the outside of the side plates a10 and the side plates b11.

[0030] The positioning rods 13 on side plate a10 and side plate b11 are inserted together. After the insertion is completed, the limiting frame 5 is put into the outside. The limiting frame 5 limits and fixes side plate a10 and side plate b11 to ensure the connection stability of the structure.

[0031] The side plates a10 and b11 abut against the base plate 2 via the support block 6, and the limiting frame 5 abuts against the upper end of the support block 6 for support.

[0033] An external air pump is connected to the inflation end 7, which causes the air bag 16 to expand. After the air bag 16 expands, it applies pressure to the surface of the poured concrete. The pressure causes the air bubbles inside the concrete to burst, thus preventing the presence of too many air bubbles inside the concrete.

[0034] The positioning mechanism includes positioning posts 4 that are fixedly connected to the lower end face of the upper cover 1. The upper end face of the base plate 2 is provided with positioning grooves 3 that mate with the lower end of the positioning posts 4.
