Description

Technical Field

[0001] This utility model relates to the field of construction insulation board technology, specifically to a winter construction insulation template device. Background Technology

[0002] Winter construction is often a season prone to quality accidents in foundation engineering due to adverse external factors such as construction conditions, cold climate, and natural environment. These accidents typically only begin to surface in the spring, making them more difficult to handle and potentially causing irreparable losses and rework. To ensure the smooth progress of winter construction, insulated formwork is needed to improve construction quality, efficiency, and safety. This is because the hydration rate of concrete decreases at low temperatures. If concrete is exposed to a cold environment after pouring, strength growth is inhibited, leading to cracks and insufficient early strength. Therefore, thermal resistance and insulation are required to maintain the temperature of the pouring area within a reasonable range, promote cement hydration, shorten curing time, and improve the consistency of early strength. Insulation boards can also reduce thermal bridging and heat loss, prevent localized freezing, and improve construction efficiency and surface quality.

[0003] A document with publication number CN217151203U discloses a constant-temperature formwork for winter construction, relating to the field of building engineering technology. It includes a formwork body made of thermally conductive material, an insulation layer fixed to the outside of the formwork body, a heating layer located between the insulation layer and the formwork body, a temperature sensor, a temperature controller, and a power supply module. The temperature controller is electrically connected to the power supply module via wires and is configured to control the heating power of the heating layer. The inner surface of the formwork body has a pre-set mounting groove, and the temperature sensor is embedded in the mounting groove and connected to the temperature controller via wires. This novel design, through temperature control, maintains the concrete surface within a suitable temperature range for strength development, preventing frost damage and safety accidents, while also saving energy in the process.

[0004] The aforementioned winter construction constant temperature formwork is made of rigid material. However, during construction, the areas that need insulation boards to cover and keep warm are not all the same shape. Rigid insulation boards have certain shortcomings in terms of fit and adaptability to curved surfaces, and have poor fit to curves, rounded corners, and complex contours. Utility Model Content

[0005] To address the issue that traditional constant temperature formwork for winter construction is made of rigid material, and that construction projects require insulation boards to cover areas of various shapes, rigid insulation boards have certain shortcomings in terms of fit and adaptability to curved surfaces, and have poor fit to curves, rounded corners, and complex contours, this utility model provides a winter construction insulation formwork device.

[0006] A winter construction insulation template device includes an insulation panel, wherein the insulation panel includes a flexible insulation component and an edge sealing component for tightly fitting the edge of the insulation panel to the construction surface;

[0007] The flexible insulation component includes a flexible hollow layer, a flexible connecting layer, two end hollow layers, and a heating tube. The two end hollow layers are fixedly connected by the flexible connecting layer and the flexible hollow layer to form a continuous and flexible insulation main structure. The heating tube is housed within the space enclosed by the flexible hollow layer, the flexible connecting layer, and the two end hollow layers.

[0008] Preferably, the flexible connecting layer includes a flexible connecting strip and a flexible corrugated wrapping layer fixedly disposed on the flexible connecting strip.

[0009] Preferably, limiting bands are fixedly provided on the inner side of the flexible hollow layer, between the flexible connecting strip and the flexible corrugated wrapping layer, and on the inner side of the two end hollow layers. The limiting bands are used to restrict the position of the heating tube in the space.

[0010] Preferably, the flexible hollow layer, the flexible connecting strip, and the outer surfaces of the two end hollow layers are all fixedly provided with soft pads.

[0011] Preferably, the edge sealing component includes an airbag fixedly disposed on the outer periphery of the insulation plate, and the airbag is provided with an inflation / deflation nozzle for inflating or deflating it.

[0012] Preferably, the airbag is arranged in a ring around the outer periphery of the insulation plate, and the soft pad strip is disposed on the inner side of the airbag.

[0013] Preferably, the flexible hollow layer, the flexible connecting layer, and the two end hollow layers are all composed of a protective layer, a reinforcing layer, a heat-insulating core layer, and a soft bottom layer stacked sequentially from the outside to the inside.

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

[0015] If the insulation panel needs to insulate curved areas, the soft pad strip can be placed against the surface of the insulation area, and the insulation panel can be pressed and smoothed along the curved surface of the insulation area. This causes the flexible hollow layer, flexible connecting layer, and the two end hollow layers to bend and wrap around the outer surface of the insulation area. The air bladder is then inflated through the air inflator to make it fit the surface of the insulation area where the insulation panel is laid. This allows the insulation panel to adapt to irregular surfaces and improves the adaptability of the insulation panel to irregular shapes. Attached Figure Description

[0022] The following combination Figures 1-4 The embodiments of this utility model will be described in detail below.

[0023] This utility model provides a winter construction insulation formwork device, which is suitable for the insulation and curing of concrete and other structures in low-temperature environments in building engineering, and is especially suitable for construction areas with curved or irregular shapes.

[0024] like Figures 1-4 As shown, it includes an insulation panel 1, which includes a flexible insulation component and an edge sealing component for tightly fitting the edge of the insulation panel 1 to the construction surface. The flexible insulation component has a certain degree of flexibility and bendability while achieving the insulation effect. It can be shaped along curves, irregular contours or complex shapes and is suitable for use in various building scenarios.

[0025] The flexible insulation component includes at least one flexible hollow layer 11, at least two flexible connecting layers 12, two end hollow layers 13, and a heating pipe 14.

[0026] In a preferred embodiment of this utility model, the two end hollow layers 13 are the two side edges of the insulation plate 1. The flexible hollow layer 11 and the flexible connecting layer 12 are disposed between the two end hollow layers 13. The number of flexible hollow layers 11 and flexible connecting layers 12 can be set by the user. The two end hollow layers 13 are fixedly connected by the flexible connecting layer 12 and the flexible hollow layer 11. The two adjacent flexible hollow layers 11 are also connected by the flexible connecting layer 12, thereby forming a continuous and flexible insulation main structure.

[0027] The flexible connecting layer 12 includes a flexible connecting strip 121 and a flexible corrugated wrapping layer 122 fixedly disposed on the flexible connecting strip 121. The flexible connecting strip 121 is made of a flexible material such as rubber or silicone, and its two sides are fixedly connected between adjacent flexible hollow layers 11 and end hollow layers 13, or fixed between two adjacent flexible hollow layers 11. The flexible corrugated wrapping layer 122 is preferably made of an elastic material with a corrugated structure. Like the flexible connecting strip 121, the flexible corrugated wrapping layer 122 is fixed between adjacent flexible hollow layers 11 and end hollow layers 13, or fixed between two adjacent flexible hollow layers 11, so that the two end hollow layers 13, the flexible connecting layer 12 and the flexible hollow layer 11 form a closed body.

[0028] The heating tube 14 is housed within the space formed by the flexible hollow layer 11, the flexible connecting layer 12, and the two end hollow layers 13. It generates heat through an external power supply, and the heat is evenly transferred to the surface to be insulated through the insulation plate 1, thereby achieving the function of heating and insulation of the construction area. As is well known to those skilled in the art, the working principle and wiring method of the heating tube 14 are commonplace and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0029] Limiting bands 15 are fixed to the inner side of the flexible hollow layer 11, between the flexible connecting strip 121 and the flexible corrugated wrapping layer 122, and the inner side of the two end hollow layers 13. The limiting bands 15 can be made of nylon or polyester strips and are fixed in the corresponding positions by sewing, bonding or riveting to limit the position of the heating tube 14 in the space and prevent it from shifting or gathering during bending.

[0030] A soft pad 16 is fixed to the outer surface of the flexible hollow layer 11, the flexible connecting strip 121, and the two end hollow layers 13. The soft pad 16 is preferably made of polyurethane or rubber and is set on the upper surface of the above components by adhesive, hot pressing, or mechanical fixing. It is used to provide cushioning and protection when the insulation board 1 comes into contact with the construction surface. When the flexible hollow layer 11, the flexible connecting strip 121, and the two end hollow layers 13 bend to a certain extent, the soft pad 16 will press against the surface of the object enclosed by the insulation board 1, which protects the enclosed object from scratches and allows the insulation board 1 to adhere to the object and maintain a certain degree of stability in position.

[0031] The edge sealing component is used to ensure that the edge of the insulation panel 1 and the enclosed object are tightly fitted together to maintain the insulation effect. The edge sealing component includes an air bladder 17 fixedly set on the outer periphery of the insulation panel 1. The air bladder 17 is arranged in a ring shape (U-shape) on the outer periphery of the insulation panel 1, and the soft pad strip 16 is set on the inner side of the air bladder 17. The air bladder 17 is provided with an inflation / deflation nozzle 18 for inflating and deflating it. After inflation, the air bladder 17 can be tightly pressed between the insulation panel 1 and the construction surface to enhance the sealing and adaptability.

[0032] In another preferred embodiment, the flexible hollow layer 11, the flexible connecting layer 12 (i.e., the whole composed of the flexible connecting strip 121 and the flexible corrugated wrapping layer 122), and the two end hollow layers 13 all adopt the same multi-layer composite structure, which includes, from the outside to the inside:

[0033] The protective layer 19 is made of waterproof and anti-aging materials, such as PVC or TPU film, and is placed on the outermost layer to resist thermal expansion and contraction caused by temperature changes.

[0034] The reinforcing layer 110, made of fiberglass mesh or polyester fabric, is placed below the protective layer 19 to improve the overall tensile strength. The fiber mesh structure provides flexible mechanical support, allowing the board to bend.

[0035] The thermal insulation core layer 111 is made of rubber foam, polyurethane foam or extruded polystyrene. The closed-cell foam structure usually has good elasticity or compressibility. It is set below the reinforcing layer 110 to provide thermal insulation function.

[0036] The soft bottom layer 112, made of foam or soft rubber, is placed in the innermost layer. After curing, it forms a tough adhesive layer that enhances adhesion and adaptability to the substrate.

[0037] In this preferred embodiment, the flexible connecting strip 121 itself is composed of the aforementioned protective layer 19, reinforcing layer 110, thermal insulation core layer 111, and soft bottom layer 112, giving it both connecting function and thermal insulation, reinforcement, and protection properties, thus maintaining consistency with the flexible hollow layer 11 and the end hollow layer 13 in performance and structure. The flexible corrugated wrapping layer 122 can be made of the same material as the protective layer 19, or a different elastic corrugated tube material, and its main function is to cover and protect the internal flexible connecting strip 121 and any possible cavities.

[0038] In addition, the layers are fixedly connected by hot pressing, gluing or sewing to form a complete composite insulation structure.

[0039] The working principle of this utility model is as follows:

[0040] If the insulation panel 1 needs to insulate the flat construction area, the side of the insulation panel 1 with the soft pad strip 16 can be placed directly on the insulation area with the side facing the insulation area. The air bag 17 can be inflated through the air inflation nozzle 18 so that the air bag 17 can fit against the surface of the insulation area where the insulation panel 1 is laid.

[0041] If the insulation panel 1 needs to insulate a curved area, the soft pad strip 16 can be placed against the surface of the insulation area, and the insulation panel 1 can be pressed and smoothed along the curved surface of the insulation area. This causes the flexible hollow layer 11, the flexible connecting layer 12, and the two end hollow layers 13 to bend and wrap around the outer surface of the insulation area. Then, the air bag 17 is inflated through the air inflator 18 so that the air bag 17 can fit against the surface of the insulation area where the insulation panel 1 is laid. This allows the insulation panel 1 to adapt to irregular surfaces and improves the adaptability of the insulation panel to irregular shapes.

[0042] It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0043] Furthermore, in this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this utility model should be included within the scope of protection of this utility model.
