Description

Technical Field

[0001] This invention relates to the field of prefabricated building technology, and in particular to a prefabricated, formwork-free, integrated structure combining insulation, decoration, and structure. Background Technology

[0002] In building construction, after the wall reinforcement of a cast-in-place concrete shear wall structure is tied, wooden, steel, or aluminum formwork is installed to form a cavity. Tie bolts and clamps are used to connect, fix, and reinforce the formwork. The installation process requires a large number of formwork and carpentry workers, making it time-consuming and labor-intensive. Inadequate formwork reinforcement can easily lead to bulging or collapse. After the concrete has hardened, the formwork needs to be removed, but regardless of whether it's wooden, steel, or aluminum, demolding is difficult, potentially causing damage to both the wall and the formwork itself.

[0003] Traditional wooden formwork, steel formwork, and aluminum formwork technologies have long construction periods, huge formwork losses, low formwork reuse rates, and high labor intensity. Furthermore, after the completion of a building using traditional wooden formwork, the subsequent construction of insulation and decorative layers suffers from drawbacks such as long construction periods, low efficiency, high costs, short service life, and subsequent detachment and maintenance.

[0004] Traditional exterior wall construction involves dangerous high-altitude operations during the construction of both the insulation and decorative layers. At the same time, the construction of the decorative layer generates pollutants such as nitrogen oxides and volatile organic compounds, which pollute the air.

[0005] The extensive use of timber formwork in the construction industry has exacerbated environmental pollution in my country. Timber harvesting and timber formwork processing generate carbon emissions, impacting climate change. The large-scale use of timber formwork accelerates the depletion of forest resources, further disrupting the ecological balance. Furthermore, discarded timber formwork is often discarded instead of recycled, leading to resource waste and environmental pollution. Summary of the Invention

[0006] The purpose of this invention is to provide a prefabricated, formwork-free, integrated structure that combines insulation, decoration, and structure, thereby improving construction efficiency and reducing construction costs.

[0007] To achieve the above objectives, the present invention provides the following solution:

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] The purpose of this invention is to provide a prefabricated, formwork-free, integrated structure that combines insulation, decoration, and structure, thereby improving construction efficiency and reducing construction costs.

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] refer to Figures 1 to 6A prefabricated, formwork-free, integrated insulation, decoration, and structural structure includes an exterior wall unit, an exterior wall connecting unit for connecting the exterior wall units, an interior wall unit, an interior wall connecting unit for connecting the interior wall units, and an interior and exterior wall connecting unit for connecting the exterior wall units and the interior wall units. Each of the exterior wall units, interior wall units, exterior wall connecting units, interior wall connecting units, and interior and exterior wall connecting units includes opposing building panels and connectors for connecting the building panels. A filling cavity for filling concrete is formed between the building panels. This invention utilizes a pre-existing structural element that is peeled off from the building structure itself. During construction, this peeled-off structure serves as a template, possessing the necessary strength and support effect, completely replacing wooden or steel / aluminum templates. The entire construction process requires no templates or supports, significantly reducing the consumption of timber, steel, and aluminum in the construction field. It is energy-saving and environmentally friendly, and the overall construction cost is lower than traditional processes. This technology has advantages such as low labor requirements, fast construction speed, energy saving and earthquake resistance, and low cost, making it suitable for various types of buildings in urban and rural construction.

[0036] Concrete is poured into the cavity within the exterior wall unit, organically bonding the insulation board to the concrete. This eliminates the risk of hollowing, cracking, and detachment of the insulation layer, avoiding maintenance and rework. It achieves integration of building insulation, decoration, and structure, ensuring the insulation and decoration have the same lifespan as the building itself. This completely eliminates the need for exterior wall plastering and decoration, further improving construction efficiency. Simultaneously, the high-strength cement board connectors on the inner side of the exterior wall effectively bond the high-strength cement board to the concrete, and the reinforcement provided by the connectors further prevents the high-strength cement board from peeling off.

[0037] Furthermore, the building materials are insulation boards or cement boards. The insulation boards are EPS boards, XPS boards, rock wool boards, or integrated insulation and decoration boards, and the cement boards are high-strength fiber cement boards or calcium silicate boards.

[0038] Furthermore, the insulation board can be used as a template, or the insulation board and decorative board can be fixed together with connectors. The decorative board can be a fired exterior wall brick, marble brick, or cement decorative board. The construction is simple and convenient, and it also enhances the aesthetics of the entire building structure.

[0039] refer to Figure 1 Both the exterior wall unit and the exterior wall connection unit include insulation boards and cement boards that are spaced apart from each other. The cement boards and the insulation boards are fixedly connected by the connectors, and a filling cavity for filling concrete is formed between the insulation boards and the cement boards.

[0040] refer to Figure 4 The insulation board and the cement board of the external wall connection unit are both L-shaped boards, and the cement board and the insulation board are arranged at intervals and their corresponding sides are parallel to each other.

[0041] Furthermore, the inner wall unit and the inner wall connecting unit include cement boards arranged opposite each other, the cement boards are fixedly connected by the connector, and a filling cavity for filling concrete is formed between the cement boards.

[0042] Furthermore, the cement boards of the inner wall connection unit are all L-shaped boards, and the cement boards are arranged at intervals and their corresponding sides are parallel to each other.

[0043] Furthermore, one of the cement boards in the inner wall unit is a straight board, and the other side is an L-shaped cement board arranged opposite to it. One side of the L-shaped cement board is parallel and spaced apart from the straight cement board, and the other side is spaced apart from the opposite cement board. A three-way cavity for filling concrete is formed between the cement boards.

[0044] refer to Figure 3 The insulation board of the inner and outer wall connection unit is a straight board, and the cement board is an L-shaped board. One side of the cement board is parallel and spaced apart from the insulation board, and the other side is spaced apart from the adjacent cement board. The cement boards are fixed together and between the cement board and the insulation board by connectors. A three-way cavity for filling concrete is formed between the insulation board and the cement board and between the cement board and the cement board.

[0045] Furthermore, the horizontally oriented exterior wall unit, interior wall unit, exterior wall connection unit, interior wall connection unit, and interior-exterior wall connection unit are all connected by tongue and groove joints at the left and right ends. The vertically oriented exterior wall unit, interior wall unit, exterior wall connection unit, interior wall connection unit, and interior-exterior wall connection unit are all connected by corresponding tenons and grooves at the top and bottom ends. At least two tenons are provided on each end face, and they are symmetrically arranged with respect to the axis of the exterior wall unit. The grooves are correspondingly provided with the tenons and can be interlocked to form a stepped joint.

[0046] Furthermore, the insulation board has evenly distributed dovetail grooves on one or both sides, which ensures that the insulation board can be organically bonded with concrete or mortar.

[0047] refer to Figure 5 Notches for window installation are made at the designed locations on the insulation board and cement board. After the concrete is poured, the window frame is installed, and then the window can be installed.

[0048] refer to Figure 6 Notches for installing the door are made at the designed locations on the insulation board and cement board. After the concrete is poured, the door frame is installed, and then the door panel can be installed.

[0049] refer to Figure 7The cement board is designed with a raised shape and installed at intervals with the insulation board. The size of the raised part is set according to the design requirements. After the concrete is poured, the wall support column is formed.

[0050] Furthermore, in this invention, both cement boards and insulation boards can be modified in size or shape according to design requirements, thereby forming a building structure that meets production needs.

[0051] Any adaptive changes made according to actual needs are within the scope of protection of this invention.
