Abstract
Description
Technical Field
[0001] The present invention relates to a resin formwork combination for concrete buildings, which has the advantages of improving concrete placement during construction, standardized classification structure design of reusable resin formwork, RFID (Radio Frequency Identification), construction efficiency and safety, and further has the characteristics of environmental consideration and green building.
Background Art
[0002] For reinforced concrete construction work, after tying steel bars and assembling formwork on-site based on construction drawings, concrete is placed in the space formed by the formwork, and after the concrete dries, the formwork is disassembled, so that the formed concrete beams, columns, wall surfaces, and floor slabs can enhance their strength and toughness through the passive pressure and restraint actions imparted by the steel bars.
[0003] The assembly of formwork is the most important work item in the construction and forming process of concrete structures. According to statistics, the assembly of formwork accounts for 15 to 25% of the total construction cost due to work costs including material costs and labor costs, and formwork collapse accidents occur from time to time, resulting in extremely large losses of life and property.
[0004] Upon investigation of the cause, the general formwork material mainly adopts wooden boards, and many are fabricated and assembled on-site, so not only is the efficiency lacking, but the durability of wooden formwork is relatively low and it is usually discarded after being used 3 to 4 times. This means that on the one hand, the material cost is wasted, and on the other hand, a large amount of construction waste is generated, resulting in a large environmental burden.
[0005] To address the durability and environmental concerns associated with the aforementioned wooden formwork, a variety of formwork materials, including steel, plastic, and aluminum, are now available. While these forms are more durable and reusable than wooden formwork, the lack of standardized design and management often leads to problems at construction sites, such as difficulties in transportation, imbalances in formwork placement and distribution, and inability to flexibly adapt dimensions to site conditions.
[0006] In particular, when these formworks are used at the corners of concrete buildings, that is, at the interior corners formed at the joints between walls, floor slabs, beams, and columns, as well as at the exterior corners formed on the convex sides of beams and columns, a large amount of additional wooden timber is required for filling. As a result, these durable formworks cannot effectively replace the advantages of wooden formwork, such as ease of cutting and assembly on site, and consequently, wooden formwork remains the unavoidable choice for contractors.
[0007] As mentioned above, wooden formwork has problems such as lack of construction efficiency, low durability, waste generation, and environmental concerns. On the other hand, conventional steel formwork, plastic formwork, and aluminum formwork lack standardized design and management, and still require the use of large quantities of wooden timbers during construction, leaving various issues that need to be resolved. Therefore, based on practical experience gained in the construction industry, the inventor has developed a resin formwork combination for concrete buildings to overcome the various shortcomings of known technologies. [Overview of the project] [Problems that the invention aims to solve]
[0008] The purpose of this invention is to overcome the shortcomings of known technologies by structurally standardizing and classifying reusable resin formwork, improving construction efficiency and reducing costs for each type of resin formwork, and furthermore, by enabling buildings to conform to the trend of low-carbon construction, as the resin formwork is recoverable and reusable, and possesses environmental advantages such as energy saving and CO2 reduction. [Means for solving the problem]
[0009] This invention aims to solve the aforementioned problems based on the above findings, and its gist is as described in the claims for utility model registration below. [1] A combination of resin formwork for concrete construction, including multiple resin formworks on which concrete can be poured, Each of the aforementioned resin molds is, The resin formwork has an inner surface that contacts the concrete and an outer surface opposite to the inner surface, and the plurality of resin formworks include a flat formwork, an outer corner formwork, and an inner corner formwork. The inner corner formwork extends from one side edge of the inner plane and has a corner connecting surface that is perpendicular to the inner plane. The width of the corner connecting surface is formed to be greater than the distance between the inner plane and the outer surface, thereby enabling the corner connecting surface to contact the inner plane of the planar formwork, and at least one engaging portion is formed in a concave shape on the outer surface of the outer corner formwork. The resin formwork combination is characterized in that the engaging portion is positioned on the side edge of the outer rectangular formwork and is configured to accept the side edge of the planar formwork that abuts against the inner plane of the outer rectangular formwork from a direction perpendicular to it. [2] The resin mold combination according to [1], characterized in that the length, width, and height dimensions of each resin mold are set with 5 centimeters as the basic unit. [3] The resin mold combination according to [2], characterized in that each of the aforementioned resin molds is provided with an RFID tag on which a part number that can identify the mold is recorded. [4] The resin formwork combination according to [3], characterized in that a sensor module including an angle sensor capable of detecting the inclination state of the formwork is fixed to some or all of the plurality of resin formworks. [5] The resin formwork combination according to [4], characterized in that the sensor module includes a humidity sensor capable of detecting the humidity of concrete. [Effects of the Invention]
[0010] Compared to known technologies, the present invention has at least the following advantages:
[0011] This invention designs multiple resin formworks, classifying them into flat formwork, outer rectangular formwork, and inner rectangular formwork, with the length, width, and height of each resin formwork set using 5 centimeters as the basic unit. Setting the dimensions using 5 centimeters as the basic unit means that each dimension is set in multiples of 5 centimeters. This effectively improves the speed of formwork placement and the convenience of on-site construction, thereby increasing construction efficiency and reducing labor costs.
[0012] Detailed structural design of inner and outer corner formwork in the classification of resin formwork solves the assembly difficulties that general formwork faces when used in the corners of concrete buildings, overcomes the drawback of having to fill each corner of a building with wooden timbers in known technologies, saves a large amount of wood, and further enhances environmental effectiveness.
[0013] The material for the resin formwork is preferably ABS resin (Acrylonitrile Butadiene Styrene), which is lightweight, high-strength, high-toughness, easy to process and mold, and durable. However, it is not limited to this, as long as the resin is durable and heat-meltable. This allows for repeated use multiple times, and even after reaching the upper limit of its service life, it can be recovered and reused by heat melting, offering environmental advantages that can effectively reduce carbon dioxide emissions and enable buildings to conform to the trend of low-carbon construction.
[0014] The length, width, and height of each resin formwork are set using 5 centimeters as the basic unit, allowing for the free combination of resin formwork of various dimensions. This ensures design flexibility in formwork arrangement and effectively improves assembly speed. Furthermore, the installation of RFID tags with identification part numbers and sensor modules is advantageous for material management and monitoring and management of the construction process and construction quality.
[0015] In some or all of the plurality of resin formworks, sensor modules are provided respectively. The sensor module includes at least an angle sensor capable of detecting the horizontal angle and vertical angle of the resin formwork, and it is possible to monitor and control the construction quality and state of each resin formwork on an external management platform.
[0016] The sensor module further includes a humidity sensor capable of detecting the humidity of the concrete, and the sensor module is signal-connected to a monitoring and control unit, and it is possible for the management platform to monitor and control the state after the concrete placement construction.
[0017] The present invention performs a standardized design for a plurality of resin formworks, including classification, the basic unit of dimensions, and the formulation of identification product numbers, and systematically manages and distributes the usage quantity and position of each resin formwork through a management platform. The constructor can quickly assemble the resin formwork according to the drawing just by transporting the corresponding resin formwork to the construction site according to the identification product number arranged on the building construction drawing.
[0018] By the management platform, all resin formworks are managed and controlled throughout the entire process from inventory management, formwork distribution, transportation, construction assembly status to construction quality, and a large amount of human resources can be saved.
[0019] Hereinafter, based on the technical means of the present invention, embodiments suitable for the present invention will be listed and described with reference to the drawings.

Embodiments for Carrying Out the Invention
[0021] FIG. 1 shows the standardized classification structure of the resin formwork according to the present invention. As shown in the figure, the resin formwork of the present invention includes a plurality of resin formworks 10 capable of placing concrete. The types of the plurality of resin formworks 10 include at least a planar formwork 11 used for the planar structure of concrete, an inner corner formwork 12 used for the inner corner structure of concrete, and an outer corner formwork 13 used for the protruding part structure of concrete. The dimensions of the length, width, and height of each resin formwork 10 are set with 5 centimeters as the basic unit, and each resin formwork 10 is provided with an identification product number 14, whereby the specifications of the plurality of resin formworks 10 are standardized.
[0022] Each resin formwork 10 has an inner plane 101 in contact with concrete and an outer surface 102 on the opposite side of the inner plane 101, respectively. Further, in the resin formwork 10 classified as the inner corner formwork 12, a corner connection surface 103 extends from one side edge of the inner plane 101. The corner connection surface 103 is perpendicular to the inner plane 101, and the width of the corner connection surface 103 is formed to be larger than the distance between the inner plane 101 and the outer surface 102. Therefore, the back of the corner connection surface 103 protrudes from the outer surface 102.
[0023] Each resin formwork 10 is provided with an RFID tag 15 respectively. The identification product number 14 is recorded in the RFID tag 15. Each resin formwork 10 has individual identification conditions, facilitating management by a management platform. Further, in addition to the identification product number, information such as the number of uses and wear conditions of the resin formwork 10 may be recorded in the RFID tag 15.
[0024] In this way, by bringing the side edge of the flat formwork 11 into contact with the side edge of the corner connection surface 103 of the inner corner formwork 12 from the vertical direction shown in Figure 3 or Figure 4, and fixing the inner plane 101 of the flat formwork 11 in alignment with the corner connection surface 103 of the inner corner formwork 12, and then pouring concrete, an inner corner joint structure can be formed between walls, or between walls and beams, columns, or floor slabs. This eliminates the need to fill the corners with wooden timbers as in general formwork, and allows for the rapid assembly of resin formwork 10s together.
[0025] In implementation, the structure of the resin formwork 10, which is classified as an outer rectangular formwork 13, has an inner plane 101 and an outer surface 102 in the same way, and at least one engaging portion 104 is formed in a concave shape on the outer surface 102, and the at least one engaging portion 104 is provided on one side edge or both side edges of the outer surface 102.
[0026] In this way, the outer corner formwork 13 is brought into contact with the side edge of the flat formwork 11 from a vertical direction using the side edge having the engaging portion 104, as shown in Figure 3 or Figure 4, so that the inner planes 101 of both intersect perpendicularly. Then the outer corner formwork 13 is engaged and fixed to the side edge of the flat formwork 11 by the engaging portion 104 which is concavely formed on the outer surface 102, completing the engagement assembly between the two and forming a corner that will protrude from structural elements such as beams and columns in the building after concrete is poured.
[0027] The design, in which the engaging portion 104 is formed in a concave shape on the outer surface 102, aims to prevent the fixing elements between the formwork from protruding and obstructing the construction flow. The engagement and assembly methods for the flat formwork 11, inner corner formwork 12, and outer corner formwork 13 can be bolted, clamped, or connected to each other by quick-release members pre-installed at the joints of each resin formwork 10. Since there are a wide variety of combination methods and structures, they will not be described in detail here.
[0028] Furthermore, in implementation, some or all of the resin formwork 10 may be equipped with a sensor module 16. In a feasible embodiment, the sensor module 16 may include an angle sensor and / or a humidity sensor. The angle sensor and humidity sensor are signal-connected to a management platform, and the angle sensor can detect the horizontal and vertical angles of the resin formwork 10 during assembly, while the humidity sensor can detect the drying state of the concrete after placement is complete.
[0029] Horizontal and vertical angles are the most important conditions for concrete walls, beams, and columns, and are related to the overall structural strength of concrete buildings. In conventional construction methods, repeated inspections using portable tools are required during the assembly and construction of formwork, which is inefficient and prone to oversights. In contrast, this invention reduces human resources and improves construction quality by detecting the horizontal and vertical angles of each resin formwork 10 during assembly using the sensor module.
[0030] The administrator can use the management platform to acquire the identification part number 14 of the RFID tag 15 of each resin formwork 10 and the detection signal from the sensor module 16, and inspect, monitor, and control the position, assembly status, construction quality, and progress of each resin formwork 10.
[0031] For example, if an identification part number 14 is obtained from an RFID tag 15 of a resin formwork 10 at a construction site, it is possible to confirm whether the resin formwork 10 corresponding to the identification part number 14 matches the position it is placed in on the architectural construction drawing, and whether it is suitable for use with the resin formwork 10 of the identification part number 14.
[0032] One method for obtaining the identification part number 14 of the RFID tag 15 is, for example, to read it using a mobile terminal equipped with an RFID reader and transmit the data to a management platform, but this is not the only method.
[0033] The specific implementation method of the building construction drawing using resin formwork combination will be further explained below with reference to Figures 2 to 4. The building construction drawing shown in Figure 2 is a building construction drawing showing a part of a concrete building structure, and the building construction drawing is an overhead view. The concrete building structure shown in the figure includes wall surfaces 301, beams 302 and columns 303, with interior or exterior angles formed at the joint positions of the wall surfaces 301 together, or at the joint positions of the wall surfaces 301 and beams 302 or columns 303, and exterior angles formed on the outer convex surfaces of beams 302 and columns 303.
[0034] Figure 3 shows the structure of a local wall surface 301 in an architectural construction drawing. The wall surface 301 is a planar structure, and the joint positions between wall surfaces 301 are either interior or exterior corner structures. Corresponding to the classification of resin formwork 10 shown in Figure 1, the formwork arrangement can be completed by placing one or more planar formwork 11 (for example, QT450*1800 in the example) at each planar structure position, interior corner formwork 12 (for example, NJ1800*300 in the example) at each interior corner structure position, and exterior corner formwork 13 (for example, WJ300*300 in the example) at each protruding structure position.
[0035] Figure 4 shows a partial beam 302 structure in the architectural construction drawing, and the beam 302 also has a planar, interior angle, and exterior angle. Similarly, the formwork arrangement can be completed by placing one or more planar formwork 11 (e.g., QB200*250 in the example) at each planar structure location, interior angle formwork 12 (e.g., NJ250*300 in the example) at each interior angle structure location, and exterior angle formwork 13 (e.g., WJ250*330 in the example) at each protruding structure location.
[0036] In particular, since the length, width, and height of each resin formwork 10 in this invention are set with a basic unit of 5 centimeters, when a user arranges the formwork according to the building construction drawings, they can intuitively and quickly arrange the formwork based on the dimensions shown in the building construction drawings, thereby greatly improving work efficiency.
[0037] Furthermore, when the aforementioned architectural construction drawings are created jointly by the construction company and the construction contractor / contractor, a dimensional system based on 5 centimeters as the basic unit can be adopted during the design and drawing of the architectural construction drawings, and the formwork placement work for the resin formwork combination can be completed quickly.
[0038] On the other hand, when the construction unit is based on architectural drawings provided externally and the formwork arrangement work is carried out using a combination of resin formwork, there is a possibility that the external architectural drawings do not adopt a 5-centimeter basic unit, which may result in gaps between the formwork when arranging the resin formwork 10. In this case, it is sufficient to fill the gaps with a small amount of wooden lumber during the assembly and construction of the formwork, and this does not significantly affect work efficiency.
[0039] As described above, the resin mold of this invention has the following advantages.
[0040] (1) All resin formwork 10 in the resin formwork combination are classified into flat formwork 11, inner corner formwork 12, and outer corner formwork 13, and basic units of dimension and identification part numbers 14 are established. Through the management platform, the quantity and location of each resin formwork 10 can be systematically managed and allocated, which is advantageous for transportation management during the construction process.
[0041] (2) By designing the resin formwork 10 into flat formwork 11, inner corner formwork 12, and outer corner formwork 13, and by setting the basic unit of the length, width, and height of each resin formwork to 5 centimeters, it can be applied to most construction situations, effectively improving the speed of formwork placement and the convenience of on-site construction, increasing construction efficiency, and reducing labor costs.
[0042] (3) The material of the resin formwork 10 may be ABS resin (Acrylonitrile Butadiene Styrene), which has the properties of being lightweight, high strength, high toughness, easy to process and mold, and durable. This allows for multiple repeated uses, and even after reaching the upper limit of its service life, it can be recovered and reused by thermal melting, which has the environmental advantage of effectively reducing carbon dioxide emissions and enabling the building to conform to the trend of low-carbon construction.
[0043] (4) The management platform allows all resin formwork 10 to be managed throughout the entire process, from inventory management, formwork allocation, transportation, and construction assembly status to construction quality, thereby saving a large amount of manpower.
[0044] (5) The detailed structural design of the inner corner formwork 12 and outer corner formwork 13 in the classification of resin formwork 10 solves the problem of assembly difficulties when general formwork is used in the corners of concrete buildings, overcomes the drawback of having to fill with a large amount of wooden timber in known technology, reduces raw material and waste disposal costs, and further enhances environmental effects.
[0045] The above description and drawings illustrate preferred embodiments of the present invention and do not limit the scope of the present invention. Anything similar to or substantially identical to the purpose, structure, apparatus, features, etc., of the present invention falls within the scope of the rights of the present invention.
