Description

Technical Field

[0001] This invention relates to the field of civil engineering technology, and more specifically, to a self-curing and heat-insulating template for concrete structures. Background Technology

[0002] In construction projects, both on-site casting and factory prefabrication of concrete structures require formwork to achieve the various concrete structural forms required by the design. Currently, steel formwork is widely used for traditional concrete structure casting. However, steel formwork has drawbacks such as the inability to insulate and the inability to replenish surface moisture during the hardening process of the concrete structure. This often leads to excessive temperature differences between the surface and the interior of the concrete structure, resulting in temperature cracks, or excessively rapid consumption or loss of surface moisture, causing plastic cracks on the surface. These issues seriously affect the safety, lifespan, and aesthetics of the concrete structure.

[0003] In view of the above-mentioned shortcomings of traditional steel formwork, the present invention provides a self-curing and heat-insulating formwork for concrete structures. Summary of the Invention

[0004] The purpose of this invention is to provide a self-curing and heat-insulating template for concrete structures to solve the above-mentioned technical problems, achieve heat insulation of concrete structures, reduce the temperature difference between the surface and interior of the concrete structure, and enable the template to replenish the surface of the concrete structure with appropriate moisture, effectively inhibiting the generation of plastic cracks caused by the drying of the concrete structure surface.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a self-curing and heat-insulating template for concrete structures, comprising a template panel, wherein the top of the template panel is provided with a plurality of arrayed water replenishment holes, the bottom of the template panel is provided with a water-diffusing layer, and the bottom of the water-diffusing layer is provided with a filter layer; template ribs are provided around the top of the template panel, and the template ribs are provided with a plurality of water-permeable holes penetrating the opposite sides of the template ribs near the bottom; each of the template ribs around the top of the template panel is provided with a U-shaped locking hole at the middle; the top of the template panel is provided with a cavity, and the cavity is filled with a sponge; a partition is installed on the top of the sponge.

[0006] The present invention is further configured such that: the water-diffusion layer is made of geotextile polyester fiber, and the filter layer is made of polyester fabric.

[0007] The present invention is further configured such that the cavity height at the top of the template panel is 10-20mm.

[0008] The present invention is further configured such that the self-curing thermal insulation template is made of fiberglass or high-strength resin.

[0009] This application further discloses the application of a self-curing thermal insulation template for concrete structures, which includes connecting several self-curing thermal insulation templates to each other through U-shaped clips. The top of the several self-curing thermal insulation templates connected to each other is provided with two water inlet and outlet ports, and each of the two water inlet and outlet ports is provided with a water control valve.

[0010] In summary, the present invention has the following beneficial effects: 1. The self-curing thermal insulation template has a simple structure, low cost, convenient installation, and long service life; 2. The self-curing thermal insulation template can achieve various functions of the template by processing and modifying existing templates; 3. The self-curing thermal insulation template can be manufactured not only as a flat template but also as a curved template according to design requirements, so as to be suitable for various concrete structures; 4. The template realizes the water storage, water release, and thermal insulation functions of the sponge, the water dispersion effect of the apron layer, and the organic combination of the water permeability of the filter layer.

[0025] Example: A self-curing and heat-insulating formwork for concrete structures, such as... Figure 1-9As shown, the template includes a template panel 2. The top of the template panel 2 has several arrayed water replenishment holes 5. The bottom of the template panel 2 has a water-diffusion layer 3, and the bottom of the water-diffusion layer 3 has a filter layer 4. Template ribs 6 are provided around the top of the template panel 2. Near the bottom of the template ribs 6, there are three water-permeable holes 11 penetrating the opposite sides of the template ribs 6, with a distance of 60mm between two adjacent water-permeable holes 11. Each template rib 6 around the top of the template panel 2 has a U-shaped locking hole 8 at its center. The top of the template panel 2 has a cavity filled with sponge 1. A partition 7 is installed on top of the sponge 1. The water-diffusion layer 3 is made of geotextile polyester fiber to achieve uniform water dispersion. The filter layer 4 is made of polyester fabric. It is in contact with the concrete structure surface to replenish water to the concrete and simultaneously achieve a smooth concrete structure surface. The cavity height at the top of the template panel 2 is 10-20mm. The self-curing thermal insulation template is made of fiberglass or high-strength resin. Eight self-curing insulation panels are interconnected via U-shaped clips 8. Two water inlets / outlets 9 are located at opposite angles on the top of each of the eight interconnected panels, and each of the two inlets / outlets 9 is equipped with a water control valve 10. One inlet / outlet 9 is used for water injection, and the other for drainage. The horizontal distance between the arrayed water inlets 5 is 30mm.

[0026] The cavity is filled with sponge 1, which has excellent water absorption and heat insulation properties, with a heat insulation coefficient of approximately 0.034 W / m·K, and also has good water storage and release capabilities. The use of materials such as fiberglass and high-strength resin further enhances the insulation effect. Secondly, there is a geotextile polyester fiber drainage layer 3, whose dense microscopic mesh structure enables uniform water dispersion. Thirdly, there is a polyester fabric filter layer 4, which allows for unidirectional water migration from the drainage layer 3 to the concrete structure surface.

[0027] The installation of self-curing thermal insulation formwork before concrete structure construction and pouring is the same as that of traditional formwork, as long as it complies with the relevant industry's concrete construction specifications.

[0028] After installation, concrete structure can be poured in accordance with the concrete construction specifications of the relevant industry. About one hour before the final setting of the concrete structure is completed (the final setting time can be determined by the previous test), water is added through the water inlet until water comes out of the outlet. Then the water control valve 10 of the water inlet is closed. Water is added to each formwork, and the temperature of the water added should not be more than 10℃ different from the temperature of the concrete surface.

[0029] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
