Description

Technical Field

[0001] The utility model relates to the technical field of building materials, and particularly relates to a heat-insulating formwork for high-performance building structures. Background Art

[0002] In actual applications, although the existing heat-insulating formwork for building structures has certain heat-insulating properties, there are still many limitations in terms of structural stability, strength, and the fixed combination with the building main body. First of all, when the traditional heat-insulating formwork bears various loads during the construction process, the strength of its surface layer and weather resistance are relatively weak, and it is difficult to resist the erosion of the external environment, such as wind, rain, ultraviolet rays, etc. for a long time, resulting in an impact on its service life.

[0003] Secondly, although the heat-insulating layer can provide a certain heat-insulating effect, in actual construction, the combination between the heat-insulating layer and the supporting layer is relatively loose, lacking effective structural strengthening design, resulting in poor strength and stability of the overall formwork. Especially in large buildings, the problems of detachment and deformation between the heat-insulating layer and the supporting layer are more prominent.

[0004] In addition, there are also great limitations in the fixed combination of the existing heat-insulating formwork with the building main body. Due to the lack of effective connection structure design, it is difficult for the heat-insulating formwork to be tightly combined with structures such as steel bars in the concrete pouring layer, and there are often situations of formwork detachment or displacement, affecting the construction quality and structural safety of the building.

[0005] Therefore, how to provide a solution with high strength, high stability, and capable of realizing the stable fixed combination of the heat-insulating formwork and the building main body has become an urgent problem to be solved in the existing technology. Summary of the Utility Model

[0006] Aiming at the above deficiencies existing in the prior art, the purpose of the utility model is to provide a heat-insulating formwork for high-performance building structures, which significantly improves the strength, stability, and installation efficiency of the heat-insulating formwork, and solves various problems existing in the prior art.

[0017] Leakage holes are formed in the positioning disk. The leakage holes communicate with the inner cavity of the positioning sleeve. The leakage holes and the gaps between the positioning rod and the positioning sleeve are filled with adhesive.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figures 1-5 A high-performance thermal insulation template for building structures includes a surface layer 11, a support layer 13, and a thermal insulation layer 12 which are sequentially arranged.

[0034] It also includes a reinforcement structure 2 fixed to the inner surface of the support layer 13 and buried in the thermal insulation layer 12 . The reinforcement structure 2 is vertically distributed on the support layer 13 along the horizontal and vertical directions.

[0035] It also includes a positioning sleeve 31 and a positioning rod 32 which are arranged vertically with the support layer 13, the insulation layer 12 and the surface layer 11. The positioning sleeve 31 is evenly assembled in the surface layer 11 and the insulation layer 12. The bottom end of the positioning sleeve 31 is kept in contact with the reinforcement structure 2. The positioning rod 32 is sleeved in the positioning sleeve 31 and extends through the reinforcement structure 2 and the support layer 13.

[0036] Multiple layers of downward-folded card plates A311 are fixedly connected in the positioning sleeve 31, and multiple layers of upward-folded card plates B321 are fixedly connected to the outer wall of the positioning rod 32. The card plates B321 are arranged in the positioning sleeve 31 and maintain spatial interference with the card plates A311. A positioning plate 322 is fixedly connected to the top end of the positioning rod 32, and the positioning plate 322 maintains contact with the top end of the positioning sleeve 31 and the surface layer 11.

[0037] The surface layer 11 is usually made of any one of aluminum alloy plates, fiber-reinforced plastics, or polyurethane-coated plates. The surface layer 11 needs to bear various loads during the construction process, so it is required to have high strength and stiffness. Moreover, since the surface layer 11 is often exposed to the external environment, it must have good weather resistance and be able to resist the erosion of wind, rain, ultraviolet rays, etc. on the material. In some applications, the surface layer 11 also needs to have a certain decorative effect to provide a beautiful appearance.

[0038] The insulation layer 12 is usually made of one or a combination of polystyrene foam boards, rigid polyurethane foams, rock wool boards, and phenolic foam boards. Its main function is to provide good thermal insulation performance, reduce the heat exchange between the inside and outside of the building, and improve energy efficiency. The insulation layer 12 is generally light to reduce the self-weight burden of the building.

[0039] The support layer 13 is usually made of plywood or composite material boards, which have good strength, toughness, and durability, and are easy to process and fix. The support layer 13 is usually closely combined with the main building structure, requiring convenient construction, firm connection, and providing an outer formwork function for the pouring construction of the main building.

[0040] The strengthening structure 2 is provided with multiple groups distributed horizontally and vertically, and is fixedly combined with the support layer 13, which can effectively provide the flatness and structural strength of the support layer 13. Since the insulation layer 12 covers its outside, it can also enhance the overall structural strength of the insulation layer 12.

[0041] The support layer 13, the insulation layer 12, the surface layer 11, and the strengthening structure 2 are all fixed and combined by means of pressing and bonding. The stability and strength of the combination of the support layer 13, the insulation layer 12, the surface layer 11, and the strengthening structure 2 can be further improved through the through-arranged positioning sleeves 31 and positioning rods 32.

[0042] The positioning sleeve 31 is fixed inside the surface layer 11 and the support layer 13 by bonding. The positioning sleeve 31 and the inner clamping plate A311 are made of building plastics and have a certain elasticity. During the process of inserting the positioning rod 32 and the clamping plate B321 thereon into the positioning sleeve 31, the clamping plate B321 can squeeze the clamping plate A311 to make the clamping plate A311 move towards the inner wall of the sleeve, so that the positioning rod 32 and the clamping plate B321 thereon can pass stably. After the positioning rod 32 and the positioning sleeve 31 are inserted and combined, the oppositely arranged clamping plates A311 and B321 produce spatial interference, which can limit the positioning rod 32 from disengaging from the positioning sleeve 31. The positioning rod 32 and the clamping plate B321 thereon are made of steel to ensure their structural strength and toughness.

[0043] The bottom end of the positioning rod 32 extends into the pouring layer of the main building and is tied and fixed to the reinforcing bars in the pouring layer to realize the fixed combination of the thermal insulation formwork and the reinforcing bars erected in the pouring layer, and ensure the effective pouring of concrete materials in the mold cavity.

[0044] To ensure the self - structural strength of the strengthening structure 2 and to ensure that the strengthening structure 2 can be fixedly combined with the support layer 13 and the heat - insulation layer 12, the following technical solutions are provided.

[0045] The strengthening structure 2 includes a bottom plate 21 and side plates fixedly connected to both ends of the bottom plate 21. The bottom plate 21 is in close contact with the support layer 13. The side plates include a wave segment 221 and an arc segment 222 connected to the top of the wave segment 221. The arc segment 222 is bent outward from the side plate.

[0046] The bottom plate 21 is designed to be flat, which can be effectively in close contact with the support layer 13. The wave segment 221 and the arc segment 222 provided on the two side plates on both sides can effectively improve the anti - lateral shear force effect of the strengthening structure 2, and the heat - insulation layer 12 is wrapped around the outside of the side plates.

[0047] Through the settings of the bottom plate 21, the wave segment 221 and the arc segment 222 on the side plates, the structural strength and stability of the support layer 13 and the heat - insulation layer 12 can be effectively improved.

[0048] The strengthening structure 2 forms an overall frame structure distributed horizontally and vertically by cutting and welding. At the node positions where the horizontal and vertical directions intersect, there are cushion seats 211. The bottom end of the positioning sleeve 31 is in contact with the cushion seat 211, thereby ensuring the stable installation of the positioning sleeve 31.

[0049] To ensure that the positioning sleeve 31 can be stably installed in the surface layer 11 and the heat - insulation layer 12, ensure that the positioning rod 32 can penetrate through the strengthening structure 2 and the support layer 13, and ensure that the positioning disc 322 on the positioning rod 32 can be in stable contact with the surface layer 11, the following technical solutions are provided.

[0050] Assembly through - holes A111 and assembly through - holes B121 are respectively opened on the surface layer 11 and the heat - insulation layer 12. An assembly sink 112 is opened on the surface layer 11 around the assembly through - hole A111. The positioning sleeve 31 is inserted into the assembly through - holes A111 and assembly through - holes B121, and the positioning disc 322 is nested in the assembly sink 112.

[0051] Assembly through - holes C131 and assembly through - holes D212 are respectively opened on the support layer 13 and the bottom plate 21. The assembly through - holes A111, assembly through - holes B121, assembly through - holes C131, and assembly through - holes D212 are arranged relatively. The positioning rod 32 is inserted into the assembly through - holes C131 and assembly through - holes D212.

[0052] The inner diameters of the assembly through holes C131 and D212 are smaller than those of the assembly through holes A111 and B121. The assembly through hole D212 is opened to the position of the pad 211. This design can ensure the stable assembly of the positioning sleeve 31 in the surface layer 11 and the insulation layer 12, and ensure that the positioning rod 32 passes through the positioning sleeve 31, the support layer 13 and the bottom plate 21 of the strengthening structure 2. The arrangement of the assembly sink 112 can hide the positioning disc 322 inside the surface layer 11, facilitating the flatness construction operation of the surface layer 11.

[0053] To ensure the fixed combination of the positioning rod 32 and the positioning sleeve 31 and the stability of their combination, the following technical solutions are provided.

[0054] Leakage holes 3221 are provided on the positioning disc 322. The leakage holes 3221 communicate with the inner cavity of the positioning sleeve 31. Bonding glue is filled in the leakage holes 3221 and the gaps between the positioning rod 32 and the positioning sleeve 31.

[0055] After the positioning rod 32 and the positioning sleeve 31 are inserted and combined, the bonding glue is injected through the leakage holes 3221 into the gaps between the positioning rod 32 and the positioning sleeve 31. After the bonding glue solidifies and takes shape, the positioning rod 32 and the positioning sleeve can be fixedly combined, ensuring the stability of the assembly of the positioning rod 32.

[0056] To ensure the flatness of the outer surface of the surface layer 11, a cement layer 14 is coated on the outer surface of the surface layer 11 and in the assembly sink 112. The coated cement layer 14 is leveled, and the assembly sink 112 and the positioning rod 32 and the positioning disc 322 assembled therein are blocked and hidden by the cement layer 14, which can ensure the flatness of the outer surface of the surface layer 11.

[0057] To ensure the overall aesthetic appearance of the building structure, a paint layer 15 is sprayed on the outer surface of the cement layer 14. The paint layer 15 selects materials with different colors and properties to ensure the aesthetic appearance, waterproof, fireproof and durable properties of the outer surface of the building structure.

[0058] To ensure the stability of the combination of the inner surface of the support layer 13 and the poured concrete, positioning sinks 132 are evenly provided on the inner side surface of the support layer 13. When pouring concrete for the building main body, part of the concrete can enter the positioning sinks 132. After the concrete solidifies and takes shape, it can be stably combined with the support layer 13, realizing the stable installation of the thermal insulation form on the outer side of the building main body.
