Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and specifically relates to an assembled carbon fiber template structure suitable for frame column corbels. Background Art

[0002] In the construction industry, extensive formwork is required for formwork support prior to pouring. Currently, formwork is typically made of wood or steel, but all are flat-panel structures. When a frame column has a corbel structure, the corbel has a vertical and inclined surface, with the intersection of the vertical and inclined surfaces forming a corbel angle. Using traditional flat-panel formwork for this purpose is complex and challenging. Formwork requires flat-panel formwork along the column shaft, and then along the inclined and vertical surfaces. However, gaps in the formwork can occur at the connection between the column shaft and the corbel, as well as at the external angle of the corbel. To minimize these gaps, detailed sealing treatment is required at these intersections. This formwork structure can easily create weak points at these intersections, which, under the pressure and impact of pouring mortar, can easily lead to mortar leaks or uneven surfaces during pouring. Moreover, traditional wooden formwork needs to be cut into intersecting angles when supporting the formwork at the intersection, resulting in secondary formwork processing, and the processing will generate construction waste and noise pollution.

[0025] The utility model discloses an assembled carbon fiber formwork structure suitable for frame column corbels, comprising a flat carbon fiber formwork, an assembled corbel carbon fiber formwork, a non-standard fiberglass angle steel, and a standard fiberglass angle steel. The assembled corbel carbon fiber formwork comprises a corbel external corner carbon fiber formwork and a corbel side carbon fiber formwork, wherein the corbel external corner carbon fiber formwork is disposed on one side of the corbel external corner, and the corbel side carbon fiber formwork is disposed on a side adjacent to the corbel external corner. A plurality of spliced ​​flat carbon fiber formworks are disposed on each side of the frame column shaft, and the standard fiberglass angle steel is disposed at the external corner of the column shaft. The standard fiberglass angle steel is connected to the flat carbon fiber formworks on both sides to form an assembled carbon fiber formwork for the column shaft. One side of the corbel side carbon fiber formwork is fixedly connected to the flat carbon fiber formwork of the column shaft, and the other side is fixedly connected to the corbel external corner carbon fiber formwork to form the assembled corbel carbon fiber formwork. The non-standard fiberglass angle steel is connected between the corbel external corner carbon fiber formwork and the flat carbon fiber formwork of the column shaft. The frame column is a rectangular frame column.

[0026] See Figures 1 to 4 As shown, an embodiment of the present invention provides an assembled carbon fiber formwork structure suitable for frame column corbels, which mainly includes an assembled corbel carbon fiber formwork 1, a flat carbon fiber formwork 2, a standard glass fiber angle steel 3, and a non-standard glass fiber angle steel 4.

[0027] The corbels of the frame column are located on opposite sides of the frame column body, and the assembled corbel carbon fiber formwork 1 is supported at the corbels of the frame column.

[0028] A flat carbon fiber formwork 2 is used on each side of the frame column body and is spliced ​​together with pins and pin pieces for formwork support. A standard glass fiber angle steel 3 is set at the positive corner of the column body and is connected to the flat carbon fiber formwork 2 on the two adjacent sides through pins and pin pieces to form an assembled carbon fiber formwork for the column body.

[0029] The connection between the assembled carbon fiber formwork of the bracket 1 and the assembled carbon fiber formwork of the column body is connected by non-standard glass fiber angle steel 4 through pins and pin pieces.

[0030] The assembled carbon fiber formwork at the column shaft is secured by interlocking circular fasteners 5 around the outside of the column shaft, forming a ring-shaped fastening structure. These ring-shaped fasteners are spaced along the length of the column shaft to secure the assembled carbon fiber formwork. These circular fasteners 5 utilize No. 10, 25mm thick column hoops, with spacing between them controlled to 150mm to 500mm. Furthermore, additional circular fasteners 5 should be added at the joints where the assembled carbon fiber formwork is connected by pins and pins to reinforce these weak points.

[0031] The assembled corbel carbon fiber formwork at the corbel is fixed by a steel pipe 6 in combination with a tension screw (not shown). Two parallel steel pipes 6 are respectively set at the vertical and inclined surfaces of the corbel, and the steel pipes 6 at the corbels on opposite sides of the main structure of the frame column are fixed by tension screws passing through the main structure of the frame column. The fixing structure is: fasteners (not shown) are set on the outside of the steel pipe 6, and the tension screws are threadedly connected to the fasteners to fix the steel pipe 6 on the outer surface of the formwork at the corbel. When the tension screw passes through the main structure, a hole can be opened at the bolt eye reserved in the formwork for the tension screw to pass through. The size of the tension screw should be M14 or M16, and the size of the steel pipe should not be less than φ48×2.7mm. In some embodiments, it is also acceptable to set a steel pipe.

[0032] The assembled corbel carbon fiber template 1 comprises a corbel external corner carbon fiber template 7 and a corbel side carbon fiber template 8.

[0033] The carbon fiber formwork 7 for the external corner of the corbel includes a first facade formwork 9 and a first inclined formwork 10, integrally connected at an angle greater than 90 degrees. The first facade formwork 9 is located at the facade of the external corner of the corbel, and the first inclined formwork 10 is located at the inclined surface of the external corner of the corbel. The connection between the first facade formwork 9 and the first inclined formwork 10 is located at the external corner of the corbel, and the angle between the connection between the first facade formwork 9 and the first inclined formwork 10 is the external angle of the corbel. The two sides of the carbon fiber formwork 1 for the external corner of the corbel extend outward by 400 mm to facilitate the connection of the carbon fiber formwork 8 on the side of the corbel. The integrally formed carbon fiber formwork 1 for the external corner of the corbel ensures the strength of the formwork at the external corner of the corbel, simplifies the number of traditional formwork for the external corner of the corbel, reduces the difficulty of operation and fixing when splicing the external corner of the corbel, and improves the construction quality of the external corner of the corbel.

[0034] In order to reduce the volume of the carbon fiber formwork 7 at the external corner of the corbel and make it easier to transport and store, the length of the first facade formwork and the first inclined formwork of the carbon fiber formwork 7 at the external corner of the corbel can be reduced. During the actual formwork, a flat carbon fiber formwork 18 is connected to the first facade formwork 9 to extend the length of the first facade formwork 9, and a second inclined formwork 11 is connected to the first inclined formwork 10 to extend the length of the first inclined formwork 10, thereby achieving formwork at the external corner of the corbel. The second inclined formwork 11 is customized, and its connection edge with the non-standard fiberglass angle steel 4 is an inclined surface connected to the non-standard fiberglass angle steel 4. When the second inclined formwork is not needed to be spliced, the connection plate connecting the first inclined formwork 10 and the non-standard fiberglass angle steel 4 is an inclined surface.

[0035] The corbel side carbon fiber formwork 8 is a flat plate-shaped formwork, its shape matching the shape of the corbel side. Its two sides are connected to the corbel's external corner carbon fiber formwork 7 and the flat carbon fiber formwork 2 at the column shaft via pins and tabs. When the corbel side carbon fiber formwork 8 is connected to the corbel's external corner carbon fiber formwork 7, the corbel side carbon fiber formwork 8 is located on the inner sides of the two sides of the corbel's external corner carbon fiber formwork 7.

[0036] The flat carbon fiber templates (2, 18) are both square flat template structures, the corbel external angle carbon fiber template 7 is a template structure with an angle, and the corbel side carbon fiber template 8 is a non-square flat template structure. The flat carbon fiber templates (2, 18), the corbel external angle carbon fiber template 7, and the corbel side carbon fiber template 8 are different in size, specifications, and shape, but their materials and basic structures are the same, that is, they are all made of a frame and a carbon fiber panel. The flat carbon fiber template 2 is used as an example for explanation.

[0037] The flat carbon fiber formwork 2 is made of carbon fiber material and includes a flat carbon fiber panel 12, a frame 13, a reinforcing beam 14, and ribs 15. The frame 13 is determined according to the size, specifications and shape of the formwork. Reinforcing beams 14 and ribs 15 are provided on the frame 13 to strengthen the strength of the frame 13. The reinforcing beams 14 and the ribs 15 are connected by a mortise and tenon structure, and the carbon fiber panel 12 and the frame 13 are connected by bolts. Pin holes 16 are provided around the frame 13 for splicing between flat carbon fiber formworks 2, or for connecting the adjacent standard glass fiber angle steels 3 and non-standard glass fiber angle steels 4. Reserved screw holes 17 are provided on the flat carbon fiber formwork 2 provided with reinforcing beams and ribs. When the tensioning screws need to pass through the formwork, holes are punched at the reserved screw holes 17 for the screws to pass through. The reserved screw holes 17 are located at the nodes with high strength of the frame, such as the nodes where the ribs cross, to ensure that the mechanical strength of the formwork is not affected after punching. The flat carbon fiber template 2 has a length and width of 50 mm per level, that is, the frame is divided into multiple levels by ribs to enhance the mechanical strength of the frame. The maximum width of the flat carbon fiber template 2 is 400 mm, and the length is between 200 mm and 2700 mm.

[0038] The standard fiberglass angle steel 3 is an L-shaped structure with a 90-degree angle. Its standard dimensions are L-50×50×5mm, and its length ranges from 300mm to 2400mm. When installed at the outer corners of the column, it is formed by splicing multiple standard fiberglass angle steels 3 together. The spliced ​​standard fiberglass angle steels 3 must maintain splicing continuity and cannot be broken. The two connecting edges of the standard fiberglass angle steel 3 can be connected to the flat carbon fiber formwork 2 on two adjacent sides of the column via pins and pins.

[0039] The non-standard fiberglass angle steel 4 is an L-shaped structure with an angle less than 90 degrees, including a first part and a second part connected at an angle less than 90 degrees. The angle of the non-standard fiberglass angle steel 4 is the angle between the end edge of the inclined template of the carbon fiber template of the corbel angle close to the column body and the end edge of the flat carbon fiber template 2 of the column body close to the corbel. The non-standard fiberglass angle steel 4 is integrally formed and is a customized part. The non-standard fiberglass angle steel 4 is located at the connection between the corbel and the column body. The two connecting edges of the non-standard fiberglass angle steel 4, namely the first part and the second part connected as one, one of the connecting edges is connected to the carbon fiber template 7 of the corbel angle at the corbel by a pin pin piece, and the other connecting edge is connected to the flat carbon fiber template 2 at the column body by a pin pin piece, so that the template between the column body and the corbel forms a seamless connection. By using the non-standard fiberglass angle steel 4, the template connection quality between the corbel and the column body is improved, the connection structure between the corbel and the column body is simplified, and the construction quality between the corbel and the column body is improved.

[0040] When the above connections are made through pins and pin pieces, the pins and pin pieces should be set at intervals of no more than 200mm and there should be no less than 2 pins at each connection point.
