Problems solved by technology

[0005] Inwardly inclined cylinder is a cylinder that is inclined inwardly relative to the inside and outside of the building. Generally, it is located at the bottom or top of the building, where a large amount of support needs to be provided. The radius of the column is large and the formwork is difficult to support. It is difficult to achieve sufficient firmness, and the angle of inclination is difficult to adjust
Inclined columns are more beautiful and generous than square columns, and they are used more in architectural design, but compared with square formwork, it is more difficult to fix and support the formwork

Embodiment 1

[0048] 1. According to the construction requirements, it is an inner inclined cylinder with a length of 4.2m, a radius of 40cm, and an angle of 60o with the horizontal plane. Along the inclined surface of the inner inclined cylinder, expand the cylinder according to 4 sections of column head formwork 3, column body formwork and column foot formwork, design column head formwork 3, column foot formwork bottom height a=27cm, column head formwork 3, column foot formwork top height b =27+2R / tan60=27+46.18=73.18cm', column formwork height=420-73.18-27=319.82cm.

[0049] 2. Support the formwork, first use the chassis fixing parts 7 and embedded bolts to fix the chassis 6 in parallel on the floor or foundation, and then connect the hinged end of the support rod 5 to the chassis 6; press the column formwork from bottom to top , column body, and column head are installed in sections in sequence; two outer column body half-moulds 2 are tightened with clamps 9, and the distance between cl...

Embodiment 2

[0052] 1. According to the construction requirements, it is an inner inclined cylinder with a length of 4m, a radius of 35cm, and an angle of 75o with the horizontal plane. Along the inclined surface of the inner inclined cylinder, expand the cylinder according to 4 sections of column head formwork 3, column body formwork and column foot formwork, design column head formwork 3, column foot formwork bottom height a=30.6cm, column head formwork 3, column foot formwork top height b=15+2R / tan75=30.6+18.76=49.36cm', column formwork height=400-49.36-30.6=320.04cm.

[0053] 2. Support the formwork, first use the chassis fixing parts 7 and embedded bolts to fix the chassis 6 in parallel on the floor or foundation, and then connect the hinged end of the support rod 5 to the chassis 6; press the column formwork from bottom to top , column body, and column head are installed in sections in sequence; the two outer column body half-moulds 2 are tightened with clamps 9, and the distance bet...

Embodiment 3

[0056] 1. According to the construction requirements, it is an inner inclined cylinder with a length of 3m, a radius of 40cm, and an angle of 80o with the horizontal plane. Along the inclined surface of the inner inclined cylinder, expand the cylinder according to 4 sections of column head formwork 3, column body formwork and column foot formwork, design column head formwork 3, column foot formwork bottom height a=43cm, column head formwork 3, column foot formwork top height b =20+2R / tan80=43+14.11=57.11cm, column formwork height=300-57.11-43=199.89cm.

[0057] 2. Support the formwork, first use the chassis fixing parts 7 and embedded bolts to fix the chassis 6 in parallel on the floor or foundation, and then connect the hinged end of the support rod 5 to the chassis 6; press the column formwork from bottom to top , column body, and column head are installed in sections in sequence; two outer column body half-moulds 2 are tightened with clamps 9, and the distance between clamp...

Abstract

The invention provides an inner inclined cylindrical form erecting device and a form erecting method, belongs to the technical field of building construction, and particularly relates to building inner inclined cylindrical template construction. The inner inclined cylindrical form erecting device comprises a cylindrical template and a support, and is characterized in that the cylindrical template is in a segmental structure and is formed by a column foot template (4), a column body template and a column head template (3); support rods (5) are arranged between the cylindrical template and a floor slab or a foundation, top ends of the support rods (5) are fixed with the cylindrical template, middle portions of the support rods (5) are regulated and supported through screw jacks (11), and bottom ends of the support rods (5) are connected with bottom plates (6) through rotating pieces; and the bottom plates (6) are horizontally fixed on the floor slab or the foundation. The form erecting method of the inner inclined cylindrical template by means of the inner inclined cylindrical form erecting device is provided, the support rods provided with the screw jacks are utilized to support the inner inclined cylindrical template in sectional connection from an inclined lower side. According to the inner inclined cylindrical form erecting device and the form erecting method, the number of gaps among concrete can be reduced, and safety, firmness and easy construction are achieved.

Description

technical field [0001] The invention discloses a formwork supporting device and method for an inner inclined column, belonging to the technical field of building construction, and specifically relates to the construction of an inner inclined column formwork and a support system. Background technique [0002] In the building concrete structure, it is sometimes necessary to pour concrete inner inclined cylinders. The inclined cylinders refer to the cylinders whose inclination angle is greater than 0° and less than 90° to the building. The cross section is circular and forms a certain angle with the floor. This makes it very important to ensure that the inclination angle of the formwork is accurate, the contact between the formwork and the floor is tight and grout-free, and the formwork does not deform or collapse during the concrete pouring and vibration process. [0003] The traditional fixation method of inclined cylindrical formwork is to support vertically at the bottom of...
