Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically, it relates to an assembled carbon fiber formwork reinforcement structure suitable for reinforcing the external corners of frame columns. Background Technology

[0002] In the construction industry, a large amount of formwork must be used for formwork support before pouring concrete. Currently used formwork is generally made of wood, aluminum alloy, or steel. At the external corners of frame columns, wooden formwork typically uses a long-side-wrapping-short-side method, with the formwork joints located on the side of the column and the outer side covered with wooden strips. Because the sides of the wooden formwork for frame columns are rough and uneven during processing, some grout leakage occurs after pouring, resulting in a rough finish at the external corners of the frame columns. When using assembled carbon fiber formwork for frame column support, the external corners are reinforced with fiberglass angle steel, and the formwork joints are located at the external corners of the frame columns. Due to the elasticity of carbon fiber material, weak points are easily created in this formwork support. During pouring, the pressure and impact of the poured mortar can easily cause water loss at the external corners, resulting in a rough finish. Utility Model Content

[0003] This utility model provides an assembled carbon fiber formwork reinforcement structure suitable for reinforcing the external corners of frame columns, in order to solve the technical problem that traditional formwork support systems and assembled carbon fiber formwork cannot guarantee the structural quality of the external corners of frame columns. By using angle steel reinforcement components to strengthen the formwork support at the external corners of frame columns, the construction quality is improved.

[0004] This utility model provides an assembled carbon fiber formwork reinforcement structure suitable for the external corner of a frame column, including carbon fiber formwork, fiberglass angle steel, angle steel reinforcement components, and support fasteners. Several spliced ​​carbon fiber formwork panels are laid on the outer surface of the frame column. The fiberglass angle steel and the angle steel reinforcement components are respectively located at the external corner of the frame column. The fiberglass angle steel is connected and fixed to the carbon fiber formwork panels on both sides of the displacement, and the angle steel reinforcement components are respectively connected and fixed to the fiberglass angle steel and carbon fiber formwork panels located on both sides. Several support fasteners are spaced apart along the column height direction on the outside of the formwork system formed by the spliced ​​carbon fiber formwork for reinforcement.

The angle steel reinforcement main component is an angle steel, and the triangular iron piece is fixedly connected to the center position of the angle steel reinforcement main component in the length direction by welding. The side of the angle steel reinforcement main component has bolt holes for connection according to the bolt hole module of the glass fiber angle steel.

[0011] Preferably, the supporting fastener is a square-round buckle fastener, which forms a ring-shaped fastening structure through interlocking.

[0023] This utility model relates to an assembled carbon fiber formwork reinforcement structure suitable for the external corner of a frame column. (See attached document.) Figure 1 The frame columns are square frame columns, reinforced with assembled carbon fiber formwork, including several assembleable and connectable assembled carbon fiber formwork 1, several fiberglass angle steel 2, several angle steel reinforcement components 3, and several square and round fasteners 4. Among them:

[0024] Several assembled carbon fiber formwork templates 1 are laid on the four outer surfaces of the frame column. The carbon fiber formwork templates 1 are connected to each other by pins and tabs. The carbon fiber formwork template 1 includes a frame, on which ribs and reinforcing beams are provided. Carbon fiber panels are fixedly installed on the surface of the frame, and connection holes are opened around the four sides of the frame. The panels are connected to the reinforcing beams by bolts, the ribs are connected to the reinforcing beams by mortise and tenon joints, and the reinforcing beams are connected to each other by rivets.

[0025] During formwork erection, the carbon fiber panels face the side of the frame column. Pins and tabs pass through the connection holes on the frame of the carbon fiber formwork 1 to connect and fix adjacent carbon fiber formwork 1 panels. Several fiberglass angle steels 2 and angle steel reinforcements 3 are installed at the four external corners of the frame column. The fiberglass angle steels 2 and angle steel reinforcements 3 are connected and fixed to the adjacent carbon fiber formwork 1 panels on the two sides using pins and tabs. The joints between the fiberglass angle steels 2 and angle steel reinforcements 3 are in close contact. To further improve the reliability of the connection, the fiberglass angle steels 2 and angle steel reinforcements 3 are connected and fixed with pins and tabs. The standard size of the fiberglass angle steel 2 is L-50×50×5mm, and the length is 300mm~2400mm. The formwork system for the frame column body is formed by the spliced ​​carbon fiber formwork 1, fiberglass angle steels 2, and angle steel reinforcements 3. Angle steel reinforcements 3 are preferably installed at the horizontal joints of the carbon fiber formwork 1 to strengthen the strength at those joints. The vertical spacing between two adjacent angle steel reinforcements 3 should not exceed 1200mm.

[0026] Angle steel reinforcement part 3, see Figure 2 The frame structure consists of an angle steel main component 6 and triangular iron pieces 7, connected by welding. The angle steel main component 6 is made of 40×40×3mm angle steel and is 150mm long. The triangular iron pieces 7 are located at the center of the length of the angle steel main component 6 and are fixed to the two sides of the angle steel main component 6 by welding, providing support and reinforcement to the two sides of the angle steel main component 6. The dimensions of the triangular iron pieces 7 are 35×35×3mm. The sides of the angle steel reinforcement main component 6 need to have bolt holes 5 pre-drilled according to the bolt hole modulus of the fiberglass angle steel 2. These holes are used for connecting the angle steel reinforcement 3, fiberglass angle steel 2, and assembled carbon fiber template 1 with pins and tabs, providing support and reinforcement to the assembled carbon fiber template at the external corner of the frame column, ensuring better forming quality of the external corner of the frame column.

[0027] The assembled carbon fiber formwork 1 at the column is reinforced and fastened by support fasteners surrounding the outside of the formwork. These fasteners are square-round fasteners 4, which interlock to form a ring-shaped fastening structure. This ring-shaped fastening structure is spaced along the length of the column to secure the assembled carbon fiber formwork 1 at the column. The square-round fasteners 4 are 25mm thick No. 10 column hoops, with the hoop spacing controlled between 150mm and 500mm. An additional square-round fastener 4 should be added at the joints where the assembled carbon fiber formwork 1 is connected by pins and tabs to reinforce these weak points.

[0028] When the above connections are made by pins and tabs, pins and tabs should be installed every 200mm or less, and there should be no less than two pins and tabs at each connection point. All bolt holes between the angle steel reinforcement 3 and the fiberglass angle steel 2 should be connected.
