[0022] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0023] Those skilled in the art will appreciate that, in the absence of conflict, the features in the following embodiments and implementations may be combined with each other.

[0024] The terms used in the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. For example, the following words indicating orientation or positional relationship, such as "upper", "lower", "inner", "outer", etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device / element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0025] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0026] In addition, in the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The SW silicon-graphene thermal insulation formwork-free structure in the embodiment of the utility model is suitable for the construction of new, expanded and renovated external insulation systems of exterior walls of civil buildings with cast-in-place concrete.

[0028] SW silicon-graphene formwork-free insulation board has Class A non-combustible performance and can be equipped with steel mesh or reinforced alkali-resistant mesh before leaving the factory, so it has sufficient mechanical strength. In new construction and existing building renovation and expansion projects, it can be used as an external insulation structural measure for cast-in-place concrete structures, which can achieve the integration of insulation and structure, making it safer and more reliable. The utility model combines the external wall insulation board method to develop an integrated SW silicon-graphene insulation formwork-free structure, fully tapping the function of the external insulation board to achieve "one board for two purposes". The external insulation board is used as both the insulation board of the wall and the template during the wall construction and pouring; therefore, the insulation board can be carried out simultaneously with the structural construction, shortening the construction period, and the external template of the structural wall column can be cancelled, saving materials and reducing the structural cost. At the same time, the insulation board and the building structure wall will achieve a safer structure such as integration, anti-falling, anti-cracking, and anti-seepage.

[0029] Reference Figures 1 to 3 As shown, this embodiment provides a SW silicon graphene insulation formwork-free structure, including an inner formwork 2, an inner support assembly supporting the inner formwork, a SW silicon graphene insulation board 3 arranged on the outside of the inner formwork, an outer support assembly supporting the SW silicon graphene insulation board, tension bolts 7 connecting the inner support assembly and the outer support assembly, wall reinforcement 1 and cast-in-place concrete arranged between the inner formwork and the SW silicon graphene insulation board and cast as one with the SW silicon graphene insulation board, an insulation board connector is provided between the wall reinforcement 1 and the SW silicon graphene insulation board 3, and a bottom support 4 supporting the bottom of the SW silicon graphene insulation board is installed at the next layer of concrete outer wall 100.

[0030] The above technical solution, in addition to the conventional formwork system, adds an auxiliary formwork structure, including an insulation board connector and a bottom support member, wherein the insulation board connector ensures the connection reliability between the SW silicon graphene insulation board and the wall, and the bottom support member facilitates the support of the SW silicon graphene insulation board at the bottom. Therefore, the utility model improves the formwork reliability of the SW silicon graphene insulation board through the above auxiliary formwork structure in conjunction with the conventional formwork system.

[0031] The inner support assembly and the outer support assembly include a vertically arranged secondary rib wood square 5 and a main rib steel tube 6 arranged perpendicularly and crosswise with the secondary rib wood square. The main rib steel tube has a model of Φ48×3.5mm, the cross-sectional size of the secondary rib wood square is 38mm×88mm, the center spacing of adjacent secondary rib wood squares is ≯125mm, and the vertical spacing of adjacent main rib steel tubes is ≯625mm.

[0032] The insulation board connector is a special connector that strengthens the connection between the external insulation formwork and the cast-in-place concrete. In this embodiment, the insulation board connector is a plastic anchor bolt, and the plastic anchor bolt is fixed to the wall reinforcement by wire binding. Ensure that the concrete is integrated with the external formwork after forming. No less than 2 are set per square meter, and they are evenly set.

[0033] Specifically, the bottom support member 4 is an angle steel, and the angle steel is fixed to the concrete outer wall by self-tapping expansion bolts. The angle steel is an equal-leg angle steel of 50×5mm, and the upper wing of the angle steel is 50mm away from the floor level.

[0034] like Figure 3 As shown, further, the joints of the SW silicon graphene insulation board are fixed with steel bar buckles 31. The joints of the SW silicon graphene insulation board are prone to cracking due to the expansion and contraction of the board, so fiberglass mesh cloth is added to the joints of the SW silicon graphene insulation board and leveled with anti-cracking mortar.

[0035] The more joints there are, the more places need to be processed, and the greater the probability of problems caused by human factors. Generally, the height of the SW silicon graphene insulation board should be the height of the floor to avoid vertical splicing. The size of the SW silicon graphene insulation board in this embodiment is 2400×1200mm. If the floor height is not enough, the whole board is cut and spliced.

[0036] Referring to the prior art, after the tension bolts are removed, a blocking column is provided to block the tension bolt holes, and the blocking column includes an insulation part corresponding to the position of the SW silicon graphene insulation board and a wall part corresponding to the cast-in-place concrete wall. Specifically, the insulation part is made of foamed polyurethane material, and the wall part is made of expanded cement or cement mortar.

[0037] SW silicon graphene insulation formwork-free structure is a new type of building energy-saving and structural integration technology system. With the current common formwork support system and auxiliary formwork structure, it can achieve excellent characteristics such as the same life of SW silicon graphene insulation board and the building. The specific advantages are as follows:

[0038] 1. Shorten the construction period: The conventional external insulation method is to first support the outer wall with formwork and pour concrete. After the wall concrete reaches a certain strength, SW silicon graphene insulation board is pasted on its outer surface. Now SW silicon graphene insulation board is also used as the template for pouring the outer wall concrete. The insulation and structure are constructed simultaneously to shorten the construction period.

[0039] 2. Project quality is easy to ensure: insulation and structure are constructed simultaneously, and the insulation layer and cast-in-place structural components form a cavity-free composite insulation system. Assisted by necessary anchoring measures, problems such as exterior wall insulation falling off and hollowing are effectively solved, greatly improving the construction quality.

[0040] 3. Easy construction: Using SW silicon graphene insulation board as a template for pouring exterior wall concrete is different from conventional methods in that it forms a whole after the concrete pouring is completed and does not need to be removed, thus eliminating the need for demolding.

[0041] 4. Save construction costs: Using SW silicon graphene insulation board as a template for pouring exterior wall concrete can save the template for exterior wall support, save about 50% of the on-site template usage, and reduce construction costs.

[0042] 5. Green and environmentally friendly: The SW silicon-graphene insulation and structural integration system greatly improves production efficiency through integrated and synchronous construction technology, ensures product quality and building quality, saves the comprehensive cost of processing and construction, reduces construction waste, shortens the project construction period, and embodies the development concept of energy conservation, emission reduction, and green environmental protection, which meets the development needs of green and low-carbon buildings.

[0043] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
