Description

Formwork for L-shaped special-shaped columns and its supporting method

technical field

The formwork support method for L-shaped special-shaped columns is specially designed for the formwork support of L-shaped special-shaped columns, and belongs to the field of building construction.

Background technique

The so-called special-shaped columns are columns with non-rectangular cross-sections; the setting of special-shaped columns is mainly due to the consideration of reducing the amount of materials and reducing the load of building components; Cross-sectional shapes such as steel, angle steel, and steel pipe, and concrete structure piles are also designed as tubular shapes, and reinforced concrete columns for factory buildings are also designed as I-shaped; it can be seen that cast-in-place reinforced concrete columns can also be designed as "T" shapes or "L" shape; columns with rectangular cross-sections are easy to formwork, and generally set vertical corrugations outside the formwork, and then use column hoops to tighten them. The formwork of special-shaped column formwork has its own particularity, such as "L " column formwork is just very difficult, because " L " column has gap with respect to rectangular cross-section column, the formwork of gap position is difficult to handle; " T " column formwork is also like this; L shaped column formwork provided by the present invention , can solve these problems.

Contents of the invention

The specific method of this plan is: according to the method shown in Figure 1, make the special-shaped column lining mold 1 of the L-shaped special-shaped column, and then the L-shaped special-shaped column can be used as a rectangular column to support the mold; the L-shaped special-shaped column formwork is made of Special-shaped column lining form 1, formwork 2, vertical stiffener 3 and column collar 4; special-shaped column lining form 1 is wrapped in formwork 2; vertical stiffener 3 stands around formwork 2; column collar 4 is horizontal The direction constrains the vertical stiffener 3 and the formwork 2 as a whole.

The special-shaped column liner mold 1 is a columnar part with a rectangular cross-section; it is recommended to use nine plywood to make it. First, use four long plates to assemble a hollow cylinder, then seal the two ends of the column flatly, and then seal the plate seam; special-shaped column liner mold 1 The side length of the section is the side length of the complete rectangular space; the height of the special-shaped column lining mold 1 is equal to the height of the column.

The formwork 2 is a plate-shaped part, and it is recommended to use nine plywood to make it first; when supporting the formwork, first arrange the vertical stiffeners 3 according to the spacing, and nail the formwork 2 and the vertical stiffeners 3 into a whole with iron nails, and arrange them according to the rectangular cross-section , the inside of the template 2 is the reinforced concrete and lining form to be poured, and the outside is restrained by the vertical stiffener 3 and the column hoop.

The vertical stiffener 3 is a rod-shaped component, and it is recommended to be made of wood with a cross-section of 50 mm wide and 80 mm high; the vertical stiffener 3 is enclosed around the formwork 2 and arranged at an interval of 150-250 mm; The outside is the column hoop 4 arranged in the horizontal direction, and the vertical stiffener 3 and the column hoop 4 perpendicularly intersect.

The column hoop 4 is a rod-shaped component, and it is recommended to use a steel pipe with a diameter of 38 mm and a wall thickness of 3.5 mm to make it; the intervals are horizontally arranged to surround the periphery of the vertical stiffener 3; the column hoop 4 made of steel pipes is fixed with right-angle fasteners Knot.

The invention also discloses a formwork method for the L-shaped special-shaped column template. Before the L-shaped special-shaped column formwork is supported, the special-shaped column lining form 1 is firstly made, and the column steel bars are bound; At the empty stomach of the special-shaped column, the L-shaped special-shaped column can be used as a rectangular column formwork at this time.

The beneficial effect of the invention is that the L-shaped special-shaped column can be easily formworked, and the formwork removal is also very convenient.

detailed description

According to the method shown in Figure 1, a certain project made a special-shaped column lining mold 1 for an L-shaped special-shaped column, and used the L-shaped special-shaped column as a rectangular column support mold; The vertical stiffener 3 and the column hoop 4 are composed; the special-shaped column lining form 1 is wrapped in the formwork 2; the vertical stiffener 3 stands around the formwork 2; the column hoop 4 connects the vertical stiffener 3 and the formwork in the horizontal direction 2 constrained into a whole.

Special-shaped column lining mold 1 is a columnar part with a rectangular cross-section; it is made of nine plywood, firstly assembled into a hollow cylinder with four long plates, then the two ends of the cylinder are flatly closed, and then the plate seam is sealed; the cross-section of special-shaped column lining mold 1 The side length is the side length of the complete rectangular space; the height of the special-shaped column lining mold 1 is equal to the height of the column.

The formwork 2 is a plate-shaped part, made of nine plywood; when supporting the formwork, the vertical stiffeners 3 are first arranged according to the spacing, and the formwork 2 and the vertical stiffeners 3 are nailed into a whole with iron nails, and arranged according to the rectangular cross section. 2. The inside is the reinforced concrete and lining form to be poured, and the outside is restrained by vertical stiffeners 3 and column hoops 4.

The vertical stiffener 3 is a rod-shaped part made of wood with a cross-section of 50 mm wide and 80 mm high; the vertical stiffener 3 is enclosed around the formwork 2 and arranged at an interval of 200 mm; the outside of the vertical stiffener 3 is horizontal The set column hoop 4, the vertical stiffener 3 and the column hoop 4 perpendicularly intersect.

The column hoop 4 is a rod-shaped part, which is made of a steel pipe with a diameter of 38 mm and a wall thickness of 3.5 mm; the intervals are horizontally arranged to enclose the periphery of the vertical stiffener 3; the column hoop 4 made of steel pipe is consolidated with a right-angle fastener at the corner.

The formwork method is as follows: before the L-shaped special-shaped column formwork, first make the special-shaped column lining form 1, and bind the column steel bars; Use the L-shaped special-shaped column as a rectangular column formwork.
