In order to win a position in the real estate field and better showcase their brands, investors have adopted high quality, high efficiency and high efficiency in residential construction as a means of competition, especially the physical quality of the building structure and the construction progress have become the focus of industry competition.

[0003] At present, the green environmental protection requirements of the construction market are gradually increasing, and the use of new materials and new technologies is constantly deepening. The use of quick-detachable aluminum alloy formwork (aluminum formwork for short) in the construction process of residential structures is more prominent, which is simple, durable, environmentally friendly and efficient. However, due to the high cost of aluminum formwork, generally only one set of wall, column, beam and plate formwork is configured, and it is only used for standard floors. The height of the wall structure of the first floor and the top floor of the building is different from that of the standard floor. The originally configured aluminum formwork cannot be used directly. If the aluminum formwork is added again, the cost is too high.

[0004] Therefore, the known configuration mode of aluminum formwork for concrete structure beams has the above-mentioned inconveniences and problems. Summary of the invention

[0005] The purpose of the present invention is to provide a safe and reliable method for reinforcing the concrete structural beams of a non-standard layer structure wall by combining aluminum formwork and wooden formwork.

[0006] To achieve the above purpose, the technical solution of the present invention is: A method for reinforcing a concrete structural beam by combining an aluminum formwork and a wooden formwork is suitable for using an aluminum formwork as a building formwork for erection, but when the height of a floor structural beam is different from the standard floor beam height, the aluminum formwork is still used for erection. The method is characterized in that it includes the following steps: a. Set up the aluminum formwork at the bottom of the beam, which is a rectangular aluminum formwork with a flat surface; b. The aluminum formwork at the lower end of the beam side and the aluminum formwork at the bottom of the beam are positioned and fixed. The aluminum formwork at the lower end of the beam side is a long aluminum formwork with a grooved cross section. The long aluminum formwork and the aluminum formwork at the bottom of the beam are fixedly arranged at the edges of both sides of the length direction of the rectangular aluminum formwork, and the flange plate on one side of the wing long aluminum formwork is fixedly attached to the rectangular aluminum formwork; c. Make and position the supporting wood; d. Make the wooden formwork for increasing the height of the beam and fix it on the supporting wooden planks; e. Position and place the aluminum formwork at the upper end of the beam side; f. Tighten the aluminum molds at the upper and lower ends of the beam side with tension screws; g. Adjust the flatness of the template inside the beam; h. Pour concrete for structural beams.

[0007] The method for reinforcing the concrete structure beam by combining aluminum formwork and wooden formwork of the present invention can also be further implemented by adopting the following technical measures.

[0008] In the aforementioned method, the specification of the tension screw is ≥Φ14mm and the length is not less than 150mm.

[0009] In the aforementioned method, the width of the aluminum template is 65 mm and the thickness of the heightened template is ≥12 mm.

[0014] The present invention is further described below in conjunction with embodiments and accompanying drawings.

[0015] Example 1 There are 25 single buildings in the residential building, with 26 floors. The standard floor height of the building structure is 2.9m, but the roof layer is 2.98m high, and the height of the building structure beam is 8cm higher than that of other standard floors. Since the residential building formwork adopts a quick-detachable aluminum formwork structure, only one set of aluminum formwork for wall columns and beams is configured. When fixing the beam side formwork of the roof layer, the aluminum formwork size is not enough to be spliced. In this regard, the concrete structure beam aluminum formwork and wooden formwork combined reinforcement method of the present invention is adopted, so that the bottom formwork of the beam is still paved with an aluminum formwork, and the beam side formwork adopts aluminum formwork at the upper and lower ends, and is reinforced by assembling and assembling wooden formwork in the middle, and the height of the original beam side aluminum formwork is increased, and the upper and lower aluminum formworks of the wooden formwork are fastened by tension screws, finally meeting the reinforcement and stability requirements of the beam side formwork.

[0016] The method for reinforcing a concrete structure beam by combining an aluminum formwork and a wooden formwork comprises the following steps: 1) Set up the aluminum formwork at the bottom of the beam; →2) Position and fix the aluminum formwork at the lower end of the beam side and the aluminum formwork at the bottom of the beam; →3) Make and position the supporting wooden planks; →4) Make and fix the wooden formwork in the middle of the beam to the supporting wooden planks; →5) Position and place the aluminum formwork at the upper end of the beam side; →6) Tighten the tension screws of the aluminum formwork at the upper and lower ends of the beam side; →7) Adjust the flatness of the formwork inside the beam; →8) Pour the concrete of the structural beam.

[0017] Among them: the structural beam aluminum formwork and wooden formwork combined reinforcement system is composed of the aluminum formwork at the bottom of the beam, the aluminum formwork at the lower end of the beam side, the aluminum formwork at the upper end of the beam side, the heightening formwork in the middle of the beam, the supporting wood and the tension screw. The supporting wood and the heightening formwork are used to make up for the insufficient height of the aluminum formwork beam, ensuring that the aluminum formwork of the standard layer beam can be used for non-standard layers.

[0018] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the combined reinforcement structure of the aluminum formwork and the wooden formwork of the structural beam of the embodiment of the present invention. As shown in the figure, the aluminum formwork 7 at the bottom of the beam and the aluminum formwork 5 at the lower end of the beam side are positioned and assembled according to the requirements for assembling standard aluminum formworks, the supporting wood 2 and the heightening formwork 6 are integrally positioned on the aluminum formwork at the lower end of the beam side, and the aluminum formwork 4 at the upper end of the beam side is installed on the supporting wood, forming a sandwich structure for the supporting wood and the heightening formwork 6.

[0019] Each aluminum formwork is supported by at least one supporting wooden plank. The aluminum formworks are connected by pins to form a whole. The upper and lower aluminum formworks on the beam side are fastened by tension screws.

[0020] The tension screws 1 on both sides of the supporting wood not only ensure the fastening of the upper and lower aluminum molds on the beam side, but also prevent the supporting wood from tipping over to the left and right when subjected to force and vibration.

[0021] The supporting wood has a size of 50*80*100mm and is positioned between two tension screws. The 100mm long direction of the supporting wood is placed on the aluminum formwork, and the 80mm high direction is to increase the height of the beam.

[0022] The width of the aluminum formwork is 65mm, the thickness of the heightened formwork is 12mm, the heightened formwork is flush with the upper and lower aluminum formworks on the beam side facing the inner side of the beam, and the supporting wooden planks are close to the heightened formwork.

[0023] The hole of the tension screw is Φ14, the tension screw is Φ12, and the length is not less than 150mm. The tension screws fasten the upper and lower aluminum molds to ensure that the supporting wood is pressed tightly and does not move.

[0024] The supporting wood and the heightening formwork are positioned between the upper and lower aluminum formworks on the beam side, and are fixed to the supporting wood and the heightening formwork using two screws 3 with a length of 40 mm, so that the supporting wood and the heightening formwork form a whole.

[0025] The supporting wood and the heightening formwork are at the same height, and they are stressed at the same time when the aluminum formwork at the upper and lower ends of the beam is tightened. The supporting wood also serves as the back side of the heightening formwork to prevent the formwork from denting or tipping over during the concrete pouring process.

[0026] The specific construction operation requirements of the concrete structure beam aluminum formwork and wooden formwork combined reinforcement method of the present invention are: 1. Requirements for positioning and fixing of supporting wood and heightening formwork. The supporting wood and heightening formwork together form the heightening part of the beam and are placed on the aluminum formwork side plate at the lower end of the beam. There are screw holes on the aluminum formwork side plate. When the supporting wood is placed, it not only meets the support force requirements, but also the supporting wood must be close to the tension screws on both sides so that the screws limit the supporting wood. The supporting wood is the back side of the heightening formwork, which strengthens the rigidity of the heightening formwork. The length of the supporting wood can be adjusted according to the rigidity requirements of the heightening formwork.

[0027] 2. The overall fixing requirements of the aluminum formwork on the beam side and the heightening formwork, the height of the supporting wood and the heightening formwork is made according to the height increase required by the beam height. The heightening formwork and the supporting wood are located between the upper and lower aluminum formworks on the beam side. Therefore, the upper and lower contact surfaces of the supporting wood and the heightening formwork with the aluminum formwork side plate must be flat. Through the tensioning screws, the upper and lower aluminum formworks on the beam side are stressed, the supporting wood and the heightening formwork are clamped, and the entire beam side plate is formed as a whole. The splicing gap must meet the requirements of no leakage during the pouring of structural beam concrete, and the overall stability must ensure that the concrete vibration process does not expand the formwork at the heightening formwork.

[0028] The present invention has substantial characteristics and significant technical progress. The concrete structure beam aluminum formwork and wooden formwork combined reinforcement method of the present invention makes the bottom beam formwork still use aluminum formwork for paving, the upper and lower ends of the beam side formwork use aluminum formwork, and the middle is reinforced by assembling and assembling wooden formwork, the height of the original beam side aluminum formwork is increased, and the aluminum formwork at the upper and lower wooden forms is fastened by tension screws, finally meeting the reinforcement and stability requirements of the beam side formwork. Due to the improvement of the universal aluminum formwork support system, on the basis of the original aluminum formwork material, through technical optimization, the aluminum formwork and wooden formwork are combined for use, meeting the reinforcement effect of the non-standard layer structure wall formwork.

[0029] The combined reinforcement method of aluminum formwork and wooden formwork for concrete structural beams of the present invention was used in the Xiejiaji shantytown renovation project in Huainan City, with obvious effects, and was fully affirmed by the construction unit and the supervision unit.

[0030] The above embodiments are only for the purpose of illustrating the present invention, but not for limiting the present invention. A person skilled in the art may make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also belong to the scope of the present invention and should be defined by the claims.
