Description

TECHNICAL FIELD

[0001] The utility model relates to temperature control mould technical field, concretely relates to a concrete temperature control mould. BACKGROUND

[0002] Concrete, commonly known as concrete: is the engineering composite material that is the whole that is cemented by cementitious material. The word concrete commonly refers to cement concrete that is made of cement as cementitious material, sand and stone as aggregate, and water (may contain admixtures and additives) in a certain proportion, and is obtained by mixing. It is widely used in civil engineering. Ultra high performance concrete (UHPC) refers to a special concrete composed of high-quality cement, fine aggregate, quartz sand, high-activity mineral admixture, high-performance fiber and high-efficiency water reducing agent, which has high strength, low water absorption, strong durability and corrosion resistance.

[0003] Concrete temperature stress refers to the stress generated inside the concrete due to temperature change. During construction, concrete temperature stress often leads to temperature cracks, thereby affecting the overall structure and durability. The main cause of temperature stress is autogenous stress. Structures without any constraints or completely static on the boundary will have temperature stress if the internal temperature is nonlinearly distributed due to mutual constraints of the structure itself. For example, bridge piers, which have relatively large structure size, have low surface temperature and high internal temperature when the concrete cools down, resulting in tensile stress on the surface and compressive stress in the middle.

[0004] The patent "CN 111098403 B A concrete pipeline pouring production mold capable of recycling hydration heat" sets heat-conducting side walls on both the inner and outer sides of the pouring mold. A large amount of heat generated by the hydration reaction of the concrete during pouring is conducted to the heat exchange cavity on the outside, and the heat is stored in the intermediate heat preservation water tank through the heat-conducting pipe in the heat exchange cavity for subsequent use. However, the device has a complex structure, high cost, and is not easy to assemble and disassemble, which is not suitable for outdoor large-scale pouring production. The patent "CN 207498978 U A dismountable concrete mold for pouring heat preservation foundation" has a slot-shaped cross section, a concrete bottom plate at the bottom, and two side plates of through-bottom and through-top heat preservation concrete, respectively. The inner and outer sides of the through-top heat preservation plate are fitted with heat preservation layer dovetail grooves and concrete dovetail tenons, respectively. However, since the heat preservation layer is located inside the structure, it is not possible to monitor the temperature change inside the concrete, nor to disassemble and assemble it at any time according to the temperature. UTILITY MODEL CONTENTS

[0005] The utility model provides a concrete temperature control mould, solved the problem that mould cannot according to concrete temperature demand change to dismantle problem in time after pouring.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A kind of concrete temperature control mould, including pouring cavity in mould center and temperature control material filling cavity outside pouring cavity;Pouring cavity and temperature control material filling cavity are separated by mould inner wall, and upper end is communicated with outside;Temperature control material filling cavity is filled with temperature control material;

[0008] Mould inner wall and mould outer wall are made of hard material with good heat conductivity and high strength;The temperature control material is foamed material or silica gel containing temperature indicator.

[0009] One of the features that concrete mould needs to have is to shape and support the concrete material poured inside. However, after pouring, due to various chemical reactions inside the concrete, the temperature of the concrete will rise sharply, and then return to the ambient temperature. If it is not monitored, the cooled concrete will crack as a whole and cannot achieve the designed function. Therefore, it is necessary to monitor the temperature and adjust it in time after pouring. In terms of temperature control and heat preservation, the prior art may use a more complex structure for temperature control, and some control methods use direct built-in insulation materials. These methods have the disadvantages of not being suitable for mass production, low practicality or not timely control.

[0010] In some embodiments, the concrete temperature control mold designed by the utility model, including the pouring cavity located in the center of the mold and the temperature control material filling cavity outside the pouring cavity, the pouring cavity and the temperature control material filling cavity are separated by the inner wall of the mold, and the upper end is communicated with the outside, the inner wall of the mold and the outer wall of the mold are made of metal material with good thermal conductivity and high strength, and the shaping of the product and the internal and external conduction of heat can be realized. The temperature control material filling cavity is filled with temperature control material, since the temperature control material is located in the temperature control material filling cavity, the temperature control material filling cavity and the pouring cavity are only separated by the inner wall of the mold, the temperature of the poured concrete can be conducted to the temperature control material in time, and indication and timely control of the temperature are realized. The utility model, the temperature control material is foamed material or silica gel containing temperature indicator, the temperature indicator can change color within a predetermined range, and the addition or removal of the temperature control material is carried out through the change of temperature. For the relatively regular product to be poured, the base of the temperature control material can adopt the whole silica gel material, which can be added or removed in whole; for the special-shaped material, the base of the temperature control material can select polypropylene foamed material to adapt to different shapes, when it is necessary to remove, only adding organic solvents such as dimethylformamide can be dissolved, and after the solvent volatilizes, the cavity can be foamed again. The reason why the temperature control material is used as an important component of the utility model is that many large constructions are deeply buried in the soil layer, only the upper part is exposed to the ground, the internal temperature cannot be monitored, and the metal with good thermal conductivity is matched with the temperature control material, the temperature of the whole pouring structure can be known at any time through color change, especially when construction is carried out in winter, the detection of temperature by infrared equipment is limited, and color identification is particularly efficient. Therefore, the utility model realizes monitoring the internal temperature change of the concrete, and timely disassembling according to the temperature of the poured concrete.

[0011] Further, the hard material is iron or an alloy thereof.

[0012] In some embodiments, the iron or the alloy thereof can conduct heat at any time, and can realize shaping and supporting of the internal concrete.

[0013] Further, the concrete temperature control mold is surrounded by the inner wall of the mold, the outer wall of the mold and the bottom. In some embodiments, when the poured concrete part needs to be combined with other constructions in the later period, the prefabricated mold can maintain the relatively regular structure of the surface.

[0014] Further, the shape of the pouring cavity is consistent with the product to be poured.

[0015] In some embodiments, the shape of the pouring cavity can be a cube, a cuboid, a cylinder and other shapes designed by the manufacturer.

[0016] Further, the pouring cavity is filled with ultra-high performance concrete or ordinary concrete.

[0017] In some embodiments, the mold designed by the utility model has high adaptability to the filling material inside the pouring cavity, and is suitable for super high performance concrete, ordinary concrete and other concrete materials.

[0018] One or more technical solutions provided in the embodiments of the application have at least the following technical effects or advantages:

[0019] (1) One characteristic that a concrete mold needs to have is that it can shape and reasonably support the concrete material poured inside. However, after pouring, due to various chemical reactions inside the concrete, the temperature of the concrete will rise sharply and then return to the ambient temperature. If it is not monitored, the cooled concrete will crack as a whole and fail to achieve the design function. Therefore, it is necessary to monitor and adjust the temperature after pouring. In terms of temperature control and insulation, the existing technology may use a more complex structure for temperature control, and some control methods use directly built-in insulation materials. These methods have the disadvantages of not being used for large-scale production, low practicality, or untimely control. The concrete temperature control mold designed in this utility model includes a pouring cavity (1) located in the center of the mold and a temperature control material filling cavity (2) outside the pouring cavity (1); the pouring cavity (1) and the temperature control material filling cavity (2) are separated by the inner wall (4) of the mold and the upper end is connected to the outside; the inner wall (4) and the outer wall (5) of the mold are both made of metal materials with good thermal conductivity and high strength, which can realize the shaping of the product and the internal and external conduction of heat. Temperature control material (3) is filled into the temperature control material filling cavity (2). Since the temperature control material (3) is located inside the temperature control material filling cavity (2), the temperature control material filling cavity (2) and the pouring cavity (1) are separated only by the inner wall of the mold (4). The temperature of the poured concrete can be transferred to the temperature control material (3) in a timely manner, so as to realize the indication and timely control of the temperature. In this utility model, the temperature control material (3) is a foamed material or silicone containing a temperature indicator. The temperature indicator can change color within a predetermined range. The temperature control material (3) can be added or removed by changing the temperature. For relatively regular products to be poured, the base of the temperature control material (3) can be a whole piece of silicone material, which can be added or removed as a whole. For irregularly shaped materials, the base of the temperature control material (3) can be polypropylene foamed material to adapt to different shapes. When it needs to be removed, it can be dissolved by adding an organic solvent such as dimethylformamide. After the solvent evaporates, the cavity can be foamed again. The reason for using temperature control material (3) as an important component of this utility model is that many large structures are buried deep underground, with only the upper part exposed above the ground, making it impossible to monitor their internal temperature. However, by using a metal with good thermal conductivity in conjunction with temperature control material (3), the temperature of the entire cast structure can be known at any time through color changes. This is especially effective when infrared equipment is limited in temperature detection during winter construction, as color identification is particularly efficient. Therefore, this utility model realizes the monitoring of internal temperature changes in concrete and allows for disassembly and assembly at any time based on the temperature of the concrete after pouring.

[0020] (2)The iron or alloy thereof adopted by the utility model can conduct heat at any time, and can realize shaping and supporting of the internal concrete. When the poured concrete part needs to be combined with other structures in the later period, the prefabricated mold can maintain the relatively regular structure of its surface. The shape of the pouring cavity (1) can be a cube, a cuboid, a cylinder, and other shapes designed by the manufacturer. The mold designed by the utility model has high adaptability to the filler in the pouring cavity (1), and is suitable for super high performance concrete, ordinary concrete and other concrete materials.
