Description

Technical Field

[0001] This invention lies at the intersection of the fields of building construction technology and energy-saving, thermal, sound-insulating, and heat-insulating building materials. Specifically, it relates to a foldable, hinged building energy-saving formwork support system with an integrated aerogel insulation layer. This system not only addresses the stability and reuse issues of traditional formwork support structures, but also, through the innovative integration of an aerogel insulation layer, seamlessly integrates the formwork support system with the building's energy-saving, thermal, and sound-insulating functions. Background Art

[0002] During the construction process, in order to prevent the formwork from expanding or exploding due to the lateral pressure of concrete during the pouring of concrete, support rods are usually set on the side of the formwork to limit the occurrence of this situation. According to the authorization announcement number CN112900862A, a formwork support system is disclosed, including multiple formworks spliced in sequence around the pouring area, and multiple back ribs connected in sequence around the outer periphery of the formwork. At least one back rib is connected to a formwork support rod, and the formwork support rod and the ground are supported by a positioning device. The positioning device includes a base, a pre-embedded anchor and a tension rod. The base is provided with a connection position for connecting the formwork support rod. The pre-embedded anchor includes an anchor portion for being buried in the ground, and a positioning portion extending upward from the anchor portion and spanning above the base. One end of the tension rod is connected to the base, and the other end is supported by the positioning portion.

[0003] The aforementioned patents lack connection between the individual formwork and the supporting structure during use, requiring independent installation for each use. This prevents traditional formwork from being quickly reused. Furthermore, traditional building formwork support systems primarily focus on structural strength and ease of construction, neglecting building energy consumption. According to statistics, building energy consumption accounts for approximately 30%-40% of total energy consumption, of which heat loss from the building envelope accounts for over 50%. After traditional concrete pouring, additional exterior wall insulation and soundproofing are still required, increasing construction steps and costs.

[0004] As China's requirements for building energy efficiency continue to rise, the "General Specification for Building Energy Conservation and Renewable Energy Utilization" (GB55015-2021) clearly stipulates the thermal insulation and sound insulation performance indicators of building envelope structures. Traditional formwork support systems are unable to meet this development trend, necessitating the development of a new formwork support system that can ensure concrete pouring quality while providing excellent thermal insulation, sound insulation, and heat insulation.

[0005] In recent years, nano-aerogel has become a cutting-edge material in the field of building energy-saving, thermal insulation and sound insulation materials due to its ultra-low thermal conductivity (0.013-0.025W / (m·K)), good sound insulation and fire resistance. Aerogel materials have ultra-low density (usually 3-350kg / m 3), high porosity (80%-99.8%), and nanoscale pore size (1-100nm). Its thermal conductivity is much lower than that of traditional thermal insulation and sound insulation materials such as polystyrene foam (0.030-0.045W / (m·K)) and polyurethane foam (0.022-0.035W / (m·K)). However, pure aerogel materials are fragile, have low mechanical strength, and are not water-resistant, making them difficult to directly apply to construction processes. How to organically combine aerogel materials with traditional formwork support systems has become a technical challenge that the industry urgently needs to solve.

[0006] Therefore, the development of a folding hinged building energy-saving formwork support system with an integrated aerogel insulation and sound insulation layer can not only solve the problems of unstable connection and difficult reuse of traditional formwork support systems, but also meet the needs of building energy-saving, thermal insulation, sound insulation and heat insulation, which has important theoretical and practical significance.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The folding hinge assembly and the connecting hinge assembly are provided to ensure that the two adjacent groups of steel formwork units can be connected, so that the two adjacent groups of steel formwork units can be stably and conveniently adjusted in angle, so that the module support system as a whole can be used synchronously, thereby improving the integrity during building pouring.

Encapsulated with a special gas-barrier film, the vacuum insulation panels are ultra-thin, ultra-light, and have an ultra-low thermal conductivity, achieving maximum thermal and acoustic insulation within confined spaces. The combination of the vacuum insulation panels and pressure divider not only enhances the system's thermal and acoustic performance, but also fully utilizes the space within the formwork support system, achieving a perfect combination of structural and thermal insulation capabilities.

[0030] 4. This invention achieves a technological breakthrough in the "one-step, multi-functional" formwork support system. This allows for simultaneous construction of the building envelope's thermal insulation, sound insulation, and heat insulation during the concrete pouring process, eliminating the additional steps required for traditional exterior wall insulation and sound insulation. This significantly improves construction efficiency and reduces costs. Furthermore, the application of aerogel composite insulation and sound insulation layers and vacuum insulation panels ensures that the building envelope's thermal insulation, sound insulation, and heat insulation performance meet or even exceed national building energy-saving standards, making a significant contribution to building energy conservation and emission reduction.

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] The present invention provides: an integrated aerogel thermal insulation and sound insulation layer folding hinge type building energy-saving template support system, such as Figures 1-10 As shown, it includes several groups of interconnected steel formwork units 1;

[0044] A set of folding hinge assemblies for controlling the use angle of the two adjacent sets of steel formwork units 1 is installed on the rear part of the fitting side of each two adjacent sets of steel formwork units 1. A connecting hinge assembly for auxiliary angle adjustment is installed between the steel formwork units 1. The connection stability between the two adjacent sets of steel formwork units 1 is ensured by the provided folding hinge assembly and the connecting hinge assembly. At the same time, the use angle of the two adjacent sets of steel formwork units 1 can be quickly changed by controlling the folding hinge assembly and the connecting hinge assembly, further improving the convenience and stability of the use of the module support system; and

[0045] A support assembly for supporting the steel formwork unit 1 is installed on the rear side of each group of steel formwork units 1. The support assembly can assist the overall strength of the steel formwork unit 1, thereby improving its convenience and stability during use and reducing the time for setting up additional supports;

[0046] A layer of aerogel composite insulation and sound insulation layer 30 is attached to the inner surface of the steel formwork unit 1. This insulation and sound insulation layer has a thickness of 5-15 mm and is composed of 50-70% by weight of hydrophobic silica aerogel and 30-50% by weight of polyurethane resin, with a thermal conductivity coefficient of less than 0.025 W / (m·K). The aerogel composite insulation and sound insulation layer 30 is firmly bonded to the steel formwork unit 1 via a special interface treatment layer 31, preventing it from falling off or cracking during repeated use. The aerogel composite insulation and sound insulation layer 30 not only has excellent thermal insulation and sound insulation properties, but also provides a certain sound insulation effect, reducing ambient noise penetration by 5-8 dB, while also achieving Class A fire resistance. By integrating the aerogel composite insulation and sound insulation layer 30 on the inner surface of the steel formwork unit 1, an organic combination of the formwork support system and building energy-saving, thermal insulation and sound insulation technology is achieved. The insulation and sound insulation layer of the building envelope is simultaneously formed during the concrete pouring process, eliminating the additional steps required for traditional exterior wall insulation and sound insulation.

[0047] The folding hinge assembly includes a storage rod 15, and a group of movably extendable extension rods 19 are respectively installed at the upper and lower ends of the storage rod 15. A group of V-shaped hinge structures are installed at the end of each group of extension rods 19. A cylinder is provided inside the storage rod 15, and the cylinder can be used to synchronously control the extension or retraction of the two groups of extension rods 19, so that the V-shaped hinge structure at the end of the extension rod 19 can quickly connect the two groups of steel formwork units 1, thereby ensuring the controllability of the two adjacent groups of steel formwork units 1 during use;

[0048] The connecting hinge assembly includes two groups of connecting plates 20, each group of connecting plates 20 is bolted to a group of steel formwork units 1 on the corresponding side, and the two groups of connecting plates 20 are directly connected by a connecting hinge 24. The two groups of steel formwork units 1 are further connected by the provided connecting plates 20 and the connecting hinge 24, and the folding hinge assembly is used to assist the stability and convenience of the two adjacent groups of steel formwork units 1 during the angle adjustment process;

[0049] The support assembly includes two groups of limit seats 6 bolted to the rear side of the steel formwork unit 1, and each group of limit seats 6 is respectively installed with a group of positioning plates 8 on the left and right sides. Several groups of support rods 26 are rotatably installed on the rear side of the upper limit seat 6, and several groups of auxiliary support rods 27 are rotatably installed on the rear side of the lower limit seat 6. The set support rods 26 and auxiliary support rods 27 can complete the support of the steel formwork unit 1 by rotation, thereby improving the overall strength of the steel formwork unit 1.

[0050] Preferably, several groups of cross-supporting steel plates 2 are welded and installed inside the steel formwork unit 1, and several groups of pressure dividing plates 3 for pressure dividing are equidistantly welded on the rear side of the steel formwork unit 1. First connecting grooves 4 are symmetrically opened on the left and right sides of the steel formwork unit 1, and several groups of positioning holes 5 are opened on each side of the steel formwork unit 1. The supporting steel plates 2 arranged on the front side of the steel formwork unit 1 and the pressure dividing plates 3 arranged on the rear side of the steel formwork unit 1 can improve the overall strength of the steel formwork unit 1 to ensure that the overall device is more stable during the casting process. In addition, the first connecting grooves 4 opened on the left and right sides of the steel formwork unit 1 can accommodate the connecting hinge components, so that the two adjacent groups of steel formwork units 1 can be stably connected when the two adjacent groups of steel formwork units 1 are rotated at an angle.

[0051] The specially designed support steel plate 2 within the steel formwork unit 1 not only provides structural support but also serves as the attachment base for the aerogel composite insulation and sound insulation layer 30. By improving the surface treatment of the support steel plate 2, the surface roughness and microstructure are increased, significantly enhancing the interfacial bond strength between the aerogel composite insulation and sound insulation layer 30 and the steel formwork unit 1. This structural design enables the formwork system to simultaneously achieve high-strength support and efficient insulation and sound insulation.

[0052] Preferably, a vacuum insulation panel 32 with a thickness of 8-12 mm is installed on the back of the pressure divider 3. The vacuum insulation panel 32 adopts a three-layer structural design: the outer layer is a protective layer 34, the middle is a core material layer 35, and the inner layer is a gas barrier film layer 36 with high barrier performance. The core material layer 35 adopts a composite material of nano-scale silica powder and glass fiber. After high-temperature treatment, it is sealed under high vacuum conditions. The thermal conductivity is as low as 0.008W / (m·K), and the thermal resistance value is 5-10 times that of traditional thermal insulation and sound insulation materials of the same thickness. The vacuum insulation panel 32 is fixedly connected to the pressure divider 3 through a special card slot fixing structure 33, and can be flexibly installed or disassembled according to the energy-saving requirements of the building. The application of the vacuum insulation panel 32 further enhances the thermal insulation, sound insulation and heat insulation performance of the formwork system, and is particularly suitable for high-demand building energy-saving areas.

[0053] Furthermore, a slide groove 7 is provided inside the limit seat 6, and each group of positioning plates 8 is bolted to the steel formwork unit 1 by bolts, and a group of mounting seats 9 is fixedly installed in the middle of each group of positioning plates 8, and a group of second connecting grooves 10 are provided inside each group of mounting seats 9. The limit seat 6 and the slide groove 7 limit the force block 25, and the force block 25 itself can be moved to change the support position of the support assembly, and the force block 25 can be locked in position by bolts to achieve the problem of fixing the support assembly.

[0054] Furthermore, the V-shaped hinge structure is composed of several groups of superimposed V-shaped connecting frames 13 and positioning shaft cores 14. The positioning shaft core 14 connects each group of V-shaped connecting frames 13. The upper and lower adjacent groups of V-shaped connecting frames 13 have different use angles. Both ends of each group of V-shaped connecting frames 13 are rotated and connected to the positioning shaft core 14. Each group of V-shaped connecting frames 13 is connected through the positioning shaft core 14, so that the two ends of the V-shaped connecting frames 13 can be rotated to change the use angle between the two adjacent groups of steel formwork units 1.

[0055] It is worth noting that each set of V-shaped connecting frames 13 is provided with a groove on the inside, and a tensioning spring is installed inside each set of grooves. The tensioning spring is connected to the positioning shaft core 14. The groove on the inside of the V-shaped connecting frame 13 is used to accommodate the tensioning spring, and the high-strength tensioning spring is used to control the angles at both ends of the V-shaped connecting frame 13.

[0056] The preparation process for the aerogel composite thermal insulation and sound insulation layer 30 is as follows: first, hydrophobic silica aerogel particles (particle size 10-100 μm) are uniformly mixed with a polyurethane prepolymer, and appropriate amounts of a foaming agent, a crosslinking agent, and a catalyst are added. After thorough stirring, the mixture is applied to the inner surface of the surface-treated steel formwork unit 1, with a coating thickness of 5-15 mm. The coating is then cured for 12-24 hours under specific temperature and humidity conditions (60-80°C, 40-60% relative humidity) to form the aerogel composite thermal insulation and sound insulation layer 30 with a microporous structure. The aerogel composite thermal insulation and sound insulation layer 30 prepared by this special process not only has excellent thermal insulation, sound insulation, and heat insulation properties, but also overcomes the shortcomings of pure aerogel materials, such as fragility and water resistance, greatly improving its applicability and durability in construction.

[0057] The interface treatment layer 31 between the aerogel composite insulation and sound insulation layer 30 and the steel formwork unit 1 utilizes a special silane coupling agent modification technology to form a chemically bonded interface, significantly improving the bonding strength between the two. Testing has shown that this interface bonding strength reaches 1.2-1.5 MPa, far exceeding the national standard requirement (≥0.1 MPa), ensuring that the aerogel composite insulation and sound insulation layer 30 will not fall off or crack during repeated use of the formwork. This highly efficient interface treatment technology is one of the key innovations of this invention, resolving the technical problem of the weak bonding between high-performance insulation and sound insulation materials and traditional building formwork.

[0058] Specifically, the two ends of each group of V-shaped connecting frames 13 are stacked inside a group of connecting seats 11, and two groups of positioning rods 12 are installed at the end positions of two groups of V-shaped connecting frames 13 with different usage angles inside each group of connecting seats 11. The end of each group of V-shaped connecting frames 13 is sleeved and installed with the positioning rod 12 at the corresponding position. The connecting seat 11 is bolted to the inside of the mounting seat 9. The positioning rod 12 inside the connecting seat 11 limits the end of the V-shaped connecting frame 13, and the connecting seat 11 is bolted to the inside of the second connecting groove 10, which can improve the stability of the connection between the two groups of steel formwork units 1.

[0059] In addition, a controller 16 is provided at the rear end of the storage rod 15, and two groups of positioning frames 17 are symmetrically installed on the upper and lower outer arc surface of the storage rod 15. The upper and lower groups of positioning frames 17 are connected by two groups of handles 18. The controller 16 installed on the rear side of the storage rod 15 controls the operation of the internal cylinder of the storage rod 15, and controls the extension of the two groups of extension rods 19, so that the connecting seat 11 is stably correspondingly inserted into the internal bolt of the second connecting groove 10 to complete the positioning of the two groups of adjacent steel formwork units 1. In addition, the positioning frame 17 and handle 18 provided can facilitate the staff to hold the storage rod 15 to determine the position of the connecting seat 11.

[0060] Furthermore, each set of connecting plates 20 is provided with connecting holes 21 at the positions corresponding to the positioning holes 5. The two sets of connecting plates 20 are respectively fitted into the first connecting grooves 4 opened on the sides of the two adjacent sets of steel formwork units 1, and the connecting plates 20 are bolted to the steel formwork units 1 through locking bolts 22 and nuts 23. The connecting plates 20 and the connecting hinges 24 are completely received in the first connecting grooves 4 fitted into the two sets of steel formwork units 1. The connecting plates 20 are correspondingly inserted into the first connecting grooves 4, and the two sets of steel formwork units 1 are assisted in connecting by positioning through the locking bolts 22 and nuts 23. When the angles of the two sets of steel formwork units 1 are adjusted, the two sets of steel formwork units 1 can be assisted in connecting, thereby improving their strength of use.

[0061] Controller 16 utilizes an intelligent microprocessor design. It not only controls the expansion and contraction of the cylinder within the retracting rod 15 but also incorporates a temperature sensor, enabling real-time monitoring of temperature changes during concrete curing. This provides data support for evaluating the thermal and sound insulation performance of the aerogel composite insulation layer 30. When the temperature sensor detects a significant temperature difference, controller 16 displays the insulation and sound insulation status via LED indicators, allowing construction workers to easily assess the effectiveness of the insulation and sound insulation. This intelligent design provides the formwork support system with self-monitoring capabilities, facilitating the evaluation of building energy efficiency.

[0062] The aerogel composite insulation and sound insulation layer 30 and vacuum insulation panels 32 of the present invention work together to form a "double insulation and sound barrier" system. The aerogel composite insulation and sound insulation layer 30 is directly attached to the inner surface of the steel formwork unit 1, in direct contact with the concrete, forming a permanent insulation layer during the concrete pouring and curing process. The vacuum insulation panels 32 are installed on the back of the pressure divider 3 as a supplementary insulation layer. Working together, these two layers significantly enhance the comprehensive insulation and sound insulation performance of the entire formwork support system, meeting building energy-saving standards in various climate zones. Experimental data shows that building envelopes constructed using the present formwork system can reduce the heat transfer coefficient by 40-60%, significantly reducing heating and cooling energy consumption.

[0063] Specifically, several groups of force blocks 25 are locked and installed inside each group of limit seats 6, one end of the support rod 26 is rotatably connected to the corresponding force block 25, and one end of the auxiliary support rod 27 is rotatably connected to the corresponding force block 25. The ends of the support rods 26 and the auxiliary support rods 27 of the same group are jointly installed on the upper part of a group of positioning bases 28, and a group of connecting blocks 29 are respectively installed on the top of the positioning base 28 corresponding to the support rods 26 and the auxiliary support rods 27. The provided positioning bases 28 and connecting blocks 29 connect the support rods 26 and the auxiliary support rods 27, and the support rods 26 and the auxiliary support rods 27 can be retracted and folded so that the support assembly can be stored to reduce space occupancy. The force blocks 25 are slidably installed inside the limit seat 6, and after the position of the support assembly is determined, the position can be locked by bolts, which is convenient for targeted changes in the support position of the support assembly.

[0064] The positioning base 28 is made of a special engineering plastic material with excellent thermal conductivity and barrier properties, preventing thermal bridging. Where the support system meets the ground, an extremely low-conductivity insulation pad is designed underneath the positioning base 28 to further reduce heat loss from the ground. This detailed design eliminates the thermal bridging problem that is common in traditional formwork support systems, making the insulation and soundproofing system more complete and effective.

[0065] In the integrated construction application of the present invention, multiple sets of steel formwork units 1 are first connected into the desired shape using folding hinge assemblies and connecting hinge assemblies according to the architectural design requirements. The support assembly is then deployed, so that the support rods 26 and auxiliary support rods 27 form a stable triangular support structure with the positioning base 28. Concrete is then poured, directly contacting the aerogel composite insulation and sound insulation layer 30. After curing, the concrete forms a building envelope with a permanent insulation and sound insulation layer. Finally, the formwork support system is dismantled and prepared for the next use. This entire process completes both the concrete pouring and the insulation and sound insulation layer installation in one go, significantly improving construction efficiency and saving time and costs.

[0066] Through actual application tests of the present invention, it was found that compared with the traditional building formwork support system, the present invention has significant advantages: 1) the thermal insulation and sound insulation performance is improved by 40-60%, and the building energy consumption is reduced by 20-35%; 2) the construction period is shortened by 15-25%, and the overall cost is reduced by 10-20%; 3) the number of reuses of the system is increased by 30-50%, and the material utilization rate is greatly improved; 4) the thermal performance of the building envelope structure is stable, and there is no thermal bridge effect, which effectively solves the problem of traditional exterior wall insulation and sound insulation systems being prone to cracking and falling off.

[0067] The integrated aerogel thermal insulation and sound insulation layer folding hinged building energy-saving formwork support system of the present invention successfully realizes the innovative integration of building formwork support technology and advanced thermal insulation and sound insulation material technology. It not only solves the problems of unstable connection and difficult reuse of traditional formwork support systems, but also meets the needs of building energy conservation, thermal insulation, sound insulation and heat insulation, provides a new technical path for building energy conservation and emission reduction, and has important economic and social benefits.

[0068] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
