Description

Technical Field

[0001] This utility model relates to a single-sided, formwork-free, energy-saving wall structure. Background Technology

[0002] Currently, energy-saving insulation of traditional building envelopes is generally achieved through three technical methods: post-installed insulation layers (primarily adhesive with anchoring as a secondary method), cast-in-place concrete with precast integrated insulation materials, and prefabricated components. Post-installed insulation layers are subject to restrictions in many parts of the country due to the risk of detachment. While precast integrated insulation materials and prefabricated components effectively solve the problem of detachment during later use, they require on-site installation of inner and outer formwork, support systems, and numerous connectors, followed by extensive dismantling of the support system after construction, resulting in a low level of industrialization. Although prefabricated integrated insulation materials offer higher industrialization, factors such as component manufacturing precision, on-site hoisting accuracy, and component cost significantly limit their application.

[0003] In view of the above problems, there is an urgent need for a technology that can combine the advantages of non-removable thermal insulation formwork technology and integrated prefabricated thermal insulation component technology, while optimizing the on-site construction steps of non-removable thermal insulation formwork, improving its industrialization level, and solving the problems of production and hoisting accuracy of integrated prefabricated thermal insulation components, effectively reducing component costs, so as to promote the wider application of integrated thermal insulation structure as a safe and efficient energy-saving thermal insulation solution for building envelope structures.

[0051] diagonal brace 20 Detailed Implementation

[0052] The following description of the embodiments is with reference to the accompanying drawings, which illustrate specific embodiments in which the present invention can be implemented.

[0053] Example 1

[0054] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, this embodiment discloses a single-sided formwork-free energy-saving wall structure. This structure includes a cast-in-place base wall 1, a single-sided formwork-free device 2, and prefabricated and / or on-site installed connecting components 3. The single-sided formwork-free device 2 includes an insulation layer 21 and diagonal bracing connectors 22. The insulation layer 21 is made of insulation material with a fire rating of Class A. One end of the diagonal bracing connector 22 is connected to the insulation layer 21, and the other end protrudes from the inner surface of the insulation layer 21 and is used to pass through the inner formwork 10 to connect with the external diagonal bracing 20. The single-sided formwork-free device 2, by using insulation material with a fire rating of Class A for the insulation layer 21, effectively provides fire protection and eliminates fire hazards. The diagonal brace connector 22 is integrated with the insulation layer 21 in the factory. During on-site construction, the diagonal brace connector 22 is used to connect with the diagonal brace 20 to achieve the installation and fixation of the single-sided formwork-free device 2, thereby eliminating some on-site construction steps of the non-removable insulation formwork, effectively improving its integration, and significantly improving the production efficiency and construction and installation efficiency; it also solves the production and installation accuracy problems of the single-sided formwork-free energy-saving wall structure, reduces costs, and will more powerfully promote the safe and efficient energy-saving insulation solution technology of the integrated insulation and structure of building envelope.

[0055] The connecting component 3 includes a metal connector and an insulation material layer. The insulation material layer covers the outer surface of the metal connector, and both the metal connector and the insulation material layer penetrate the insulation layer 21 from its outer side, so that the connecting component 3 is exposed on the inner side of the insulation layer 21. The base wall 1 is cast-in-place between the single-sided formwork-free device 2 and the inner formwork 10, so that the base wall 1 is connected to the inner side of the insulation layer 21, the diagonal brace connector 22, and the connecting component 3. By connecting the connecting component 3 through the insulation layer 21 and connecting it to the cast-in-place base wall 1, the connection firmness is improved, effectively preventing falling and greatly improving the safety and stability of the single-sided formwork-free energy-saving wall structure. Moreover, the metal connector is made of metal, achieving a stable and reliable connection; the outer surface of the metal connector is covered with an insulation material layer, which effectively enhances the heat insulation effect of the single-sided formwork-free energy-saving wall structure and further overcomes the thermal bridging phenomenon. The connecting component 3 can be prefabricated in the factory and connected to the single-sided formwork-free device 2, or it can be placed on-site during construction.

[0056] In this embodiment, the base wall 1 includes wall reinforcement 11 and a cast-in-place concrete layer. The wall reinforcement 11 is erected between the inner side of the single-sided formwork-free device 2 and the inner formwork 10. The diagonal brace connector 22 passes through the wall reinforcement 11. The cast-in-place concrete layer is poured onto the wall reinforcement 11 and connected to the inner side of the insulation layer 21, the diagonal brace connector 22, and the connecting component 3. During construction, the single-sided formwork-free energy-saving wall structure is constructed with the single-sided formwork-free device 2 erected on the outer side of the wall reinforcement 11 and the inner formwork 10 erected on the inner side of the wall reinforcement 11. The single-sided formwork-free device 2 is connected to the diagonal brace 20 through the diagonal brace connector 22 passing through the wall reinforcement 11 and the inner formwork 10, thereby achieving the fixed installation of the single-sided formwork-free device 2. Then, the cast-in-place concrete layer is poured between the single-sided formwork-free device 2 and the inner formwork 10, and the cast-in-place concrete layer covers the wall reinforcement 11 to form the base wall 1. In the subsequent removal of the diagonal brace 20 and the inner formwork 10, the structure protruding from the inner side of the base wall 1 was cut off.

[0057] In this embodiment, the insulation layer 21 is a Class A fire-resistant insulation material composed of a single homogeneous material. The Class A fire-resistant insulation material effectively ensures the fire resistance and insulation performance of the single-sided formwork-free energy-saving wall structure, thus eliminating the need for additional inorganic composite boards to enhance its strength and fire resistance.

[0058] The insulation layer 21 can be made of polyurethane insulation material or silicon graphene insulation material, which effectively ensures the insulation and fire resistance of the single-sided formwork-free energy-saving wall structure and greatly improves the safety and stability of the single-sided formwork-free energy-saving wall structure.

[0059] The single-sided moldless device 2 also includes a reinforcing mesh 23, which is built into the insulation layer 21 and / or placed on the surface of the insulation layer 21. One end of the diagonal brace connector 22 extends into the insulation layer 21 and connects to the reinforcing mesh 23, and the connecting component 3 passes through the reinforcing mesh 23. During the processing of the single-sided moldless device 2, the reinforcing mesh 23 is placed on top of the raw material composition of the insulation layer 21 after the first layer of material is applied in the mold. Then, the raw material composition of the insulation layer 21 is applied a second time in the mold, so that the raw material composition of the insulation layer 21 completely wraps the reinforcing mesh 23 after the second layer of material is applied, thus realizing that the reinforcing mesh 23 is built into the insulation layer 21. Of course, the reinforcing mesh 23 can also be placed on the surface of the insulation layer 21 after the insulation layer 21 is processed. The reinforcing mesh 23 can further enhance the overall structural strength of the single-sided moldless energy-saving wall structure, greatly improving the safety and stability of the single-sided moldless energy-saving wall structure.

[0060] In this embodiment, the metal connector includes an anchor plate 31 and an anchor rod 32. The anchor plate 31 abuts against the outer side of the insulation layer 21, one end of the anchor rod 32 is connected to the anchor plate 31, and the other end of the anchor rod 32 passes through the insulation layer 21 and connects to the base wall 1. The insulation material layer covers the outer surfaces of the anchor plate 31 and the anchor rod 32. The metal connector abuts against the outer side of the single-sided formwork-free device 2 through the anchor plate 31, and connects the single-sided formwork-free device 2 to the base wall 1 through the anchor rod 32. The insulation material layer covers the outer surfaces of the anchor plate 31 and the anchor rod 32. The overall structure is simple and very convenient to use.

[0061] The outer surface of the connecting component 3 has an outwardly protruding blocking structure 33. The outwardly protruding blocking structures 33 are located on the anchor rod 32 and there are multiple of them. The multiple blocking structures 33 are closely abutted against the insulation layer 21 and the base wall 1, which further strengthens the connection strength of the single-sided formwork-free energy-saving wall structure, effectively prevents falling, and greatly improves the safety and stability of the single-sided formwork-free energy-saving wall structure.

[0062] The connecting component 3 can be connected to the wall reinforcement 11. The connecting component 3 extends into the base wall 1 through the anchor rod 32 and is connected to the wall reinforcement 11, further strengthening the structural connection strength and greatly improving the safety and stability of the single-sided formwork-free energy-saving wall structure.

[0063] The connecting component 3 can be connected to the reinforcing mesh 23. The connecting component 3 passes through the insulation layer 21 and is connected to the reinforcing mesh 23 via the anchor rod 32, which further strengthens the structural connection strength and greatly improves the safety and stability of the single-sided formwork-free energy-saving wall structure.

[0064] The diagonal brace connector 22 includes a mounting base 221 and a connecting plate 222. The mounting base 221 is disposed within the insulation layer 21. One end of the connecting plate 222 is connected to the mounting base 221, and the other end of the connecting plate 222 protrudes from the inner side of the insulation layer 21 and is connected to the base wall 1. In this embodiment, the mounting base 221 and the connecting plate 222 are separate structures. During the factory processing of the single-sided formwork-free device 2, the mounting base 221 is placed in a mold to achieve the pre-embedding of the mounting base 221 within the insulation layer 21. Subsequently, during on-site construction, one end of the connecting plate 222 is connected to the mounting base 221, and the other end passes through the wall reinforcement 11 and the inner formwork 10 to connect with the diagonal brace 20, thereby achieving the function of temporary fixation and support for the single-sided formwork-free device 2 during construction, significantly improving manufacturing and installation efficiency.

[0065] Part of the structure of the mounting base 221 is exposed on the inner side of the insulation layer 21, and the connecting plate 222 is connected to part of the structure of the mounting base 221. The connecting plate 222 is welded to the exposed portion of the mounting base 221. Alternatively, in other embodiments, the mounting base 221 and the connecting plate 222 can be integrally formed.

[0066] Specifically, the two ends of the mounting base 221 are located inside the insulation layer 21 and abut against the side of the reinforcing mesh 23 facing away from the base wall 1, thereby effectively strengthening the connection strength of the mounting base 221. The middle part of the mounting base 221 is exposed on the inner side of the insulation layer 21 and is used for welding to the connecting plate 222. The end of the connecting plate 222 away from the mounting base 221 has a connecting hole for connecting to the diagonal brace 20. After the diagonal brace 20 and the inner template 10 are subsequently removed, the connecting plate 222 protruding from the inner side of the base wall 1 is cut off.

[0067] In this embodiment, the single-sided formwork-free energy-saving wall structure also includes a pre-embedded screw component 4, which includes a pre-embedded connecting sleeve 41 and a screw 42. The pre-embedded connecting sleeve 41 is embedded in the insulation layer 21, and the screw 42 is connected to the pre-embedded connecting sleeve 41, with the screw 42 protruding from the inner side of the insulation layer 21 and connected to the base wall 1. During the factory processing of the single-sided formwork-free device 2, the pre-embedded connecting sleeve 41 is placed in a mold to achieve the pre-embedded connecting sleeve 41 being embedded in the insulation layer 21. During on-site construction, one end of the screw 42 is connected to the pre-embedded connecting sleeve 41, and the other end protrudes from the inner side of the insulation layer 21 and is connected to the base wall 1, further strengthening the connection between the single-sided formwork-free device 2 and the base wall 1, effectively preventing falling, and greatly improving the safety and stability of the single-sided formwork-free energy-saving wall structure; and significantly improving the manufacturing efficiency and construction and installation efficiency. Meanwhile, the pre-embedded connecting sleeve 41 has an internal thread for connecting with the screw 42. The pre-embedded connecting sleeve 41 and the screw 42 are connected by a thread, which is very convenient to use.

[0068] The pre-embedded connecting sleeve 41 is connected to the reinforcing mesh 23. The pre-embedded connecting sleeve 41 is located inside the insulation layer 21 and connected to the reinforcing mesh 23, further strengthening the structural connection strength and greatly improving the safety and stability of the building's energy-saving wall structure. The outer surface of the pre-embedded connecting sleeve 41 has an outwardly protruding part that abuts against the side of the reinforcing mesh 23 facing away from the base wall 1.

[0069] The length of the screw 42 can be relatively short, allowing the screw 42 to extend into and connect to the wall reinforcement 11, further strengthening the structural connection between the single-sided formwork-free device 2 and the base wall 1, and greatly improving the safety and stability of the single-sided formwork-free energy-saving wall structure.

[0070] Of course, the length of the screw 42 can also be relatively long, so that one end of the screw 42 is threaded into the pre-embedded connecting sleeve 41, and the other end of the screw 42 is used to pass through the inner formwork 10 and abut against the side of the inner formwork 10 facing away from the base wall 1, so that the cast-in-place concrete layer is poured between the single-sided formwork-free device 2 and the inner formwork 10. During on-site construction, the pre-embedded screw component 4 can be used as a tie rod, with both ends abutting against the opposite sides of the single-sided formwork-free device 2 and the inner formwork 10, respectively, improving the safety of the single-sided formwork-free energy-saving wall structure; at the same time, the manufacturing efficiency and construction and installation efficiency are significantly improved. Among them, when the diagonal brace 20 and the inner formwork 10 are subsequently removed, the screw 42 protruding from the inner side of the base wall 1 is cut off.

[0071] The single-sided formwork-free device 2 also includes a finishing layer 5, which is connected to the outer surface of the insulation layer 21. The finishing layer 5 provides enhanced protection, ensuring the proper functioning of the single-sided formwork-free device 2. The finishing layer 5 comprises mortar and a mesh fabric. The mortar is connected to the outer surface of the insulation layer 21, and the mesh fabric is embedded within the mortar. The mesh arrangement within the mortar enhances the overall structural strength of the finishing layer 5, while the mortar provides leveling and protection. Preferably, the mortar is a polymer-based crack-resistant mortar.

[0072] The single-sided formwork-free device 2 also includes a finishing layer 6, which is connected to the outer surface of the insulation layer 21. The finishing layer 6 can be directly connected to the outer surface of the insulation layer 21, or it can be directly connected to the outer surface of the plaster layer 5. The finishing layer 6 is used to protect the wall, beautify the building, and meet usage requirements. The material of the finishing layer 6 can be paint, ceramic tile, stone, metal plate, or UHPC. When the material of the finishing layer 6 is UHPC, a reinforcing mesh structure is added inside the finishing layer 6. This reinforcing mesh structure effectively strengthens the structural strength of the finishing layer 6, greatly improving the stability of the single-sided formwork-free energy-saving wall structure.

[0073] The single-sided formwork-free energy-saving wall structure also includes a limiting abutment plate 7. The two ends of the limiting abutment plate 7 abut against the inner side of the single-sided formwork-free device 2 and the inner formwork 10, respectively, and are connected to the base wall 1. The limiting abutment plate 7 effectively prevents the single-sided formwork-free device 2 and / or the inner formwork 10 from tilting inward or bulging during the pouring of the cast-in-place concrete layer. Simultaneously, the two ends of the limiting abutment plate 7 abut against the single-sided formwork-free device 2 and the inner formwork 10, respectively, allow for adjustment of the distance between them, thereby achieving precise control of the thickness of the base wall 1 and greatly improving the safety and stability of the single-sided formwork-free energy-saving wall structure.

[0074] Example 2

[0075] like Figure 4 As shown, the same parts of the single-sided formwork-free energy-saving wall structure in this embodiment as in Embodiment 1 will not be repeated; only the differences will be explained. In this Embodiment 2, the single-sided formwork-free device 2 also includes a concrete layer 24. The concrete layer 24 is poured and connected to the inner side of the insulation layer 21. The diagonal brace connector 22 and the connecting component 3 both pass through the concrete layer 24 and protrude from the inner side of the concrete layer 24. The concrete layer 24 is prefabricated and poured into the inner side of the insulation layer 21 in the factory. During construction, both sides of the concrete layer 24 are connected to the base wall 1 and the inner side of the insulation layer 21, respectively. Because the inner side of the insulation layer 21 has a concrete layer 24 of a certain thickness, the thickness of the base wall 1 can be reduced during on-site construction, further improving the production efficiency and construction and installation efficiency, and achieving higher precision.

[0076] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
