Problems solved by technology

However, the shape of the arc-shaped branch-like beam-column joints is complicated, the inner corners alternate with each other, and the formwork at the joints needs to be assembled at high altitude
In the existing technology, the pure steel formwork system is usually used, and the effect of the finished product is difficult to control
There are also problems such as heavy steel formwork, grout leakage in joints, difficult operation for workers, and high safety risks.

Embodiment 1

[0044] This embodiment discloses a steel-wood combined formwork system for fair-faced concrete arc-shaped branch-shaped beam-column joints, including a combined steel formwork 1 for the arc section at the top of the column that is fixedly connected to the base 5, and four arc steel forms 2 And 4 pieces of angle steel mold Ⅲ3.

[0045] see figure 1 , the cross-section of the column body is rounded rectangle as a whole (that is, the four corners of the rectangle are replaced by 1 / 4 arcs). Grooves are provided on the four sides of the rounded rectangle. see figure 2 , The junction between the top of the canopy column and the beam adopts an arc connection form, and the four grooves on the top of the column are connected to the beam in an arc. The widths of the four groove surfaces of the column are respectively equal to the widths of the corresponding beams.

[0046] After the pouring of the column body is completed and before the construction of the upper structure, a steel ...

Embodiment 2

[0053] This embodiment discloses a steel-wood combined formwork system for fair-faced concrete arc-shaped branch-shaped beam-column joints, including a combined steel formwork 1 for the arc section at the top of the column that is fixedly connected to the base 5, and four arc steel forms 2 And 4 pieces of angle steel mold Ⅲ3.

[0054] The base 5 is a column body steel formwork that is closed and connected to the column. The base 5 is a sash formwork closed all around. The base 5 as a whole is a rectangular frame with rounded corners. There are long grooves on the four sides of the frame. The base 5 includes 4 angle steel molds I 501 and 4 grooved panels 502 . The angle steel mold I501 includes a curved panel I5011. The two sides of the curved panel I5011 are connected with end plates I5012. The end plate I5012 is located on the concave side of the curved panel I5011. The grooved panel 502 is a straight steel plate. The four angle steel molds I501 correspond to the four ...

Embodiment 3

[0061] This embodiment discloses a construction method related to the above-mentioned formwork system, including the following steps:

[0062] 1) Construction preparation, template pre-assembly, to avoid rework.

[0063] 2) Carry out anti-corrosion treatment on the base 5, combined steel mold 1, arc steel mold 2 and angle steel mold III3.

[0064] 3) After the pouring of the lower column is completed and before the construction of the upper structure, the base 5 is installed on the top of the column, and double-sided adhesive tape is pasted on the joint between the base and the concrete to ensure that the upper structure does not leak when the concrete is poured.

[0065] 4) Install the combined steel mold 1 on the base 5, and paste double-sided adhesive tape on the junction of the templates.

[0066] 5) Install the arc steel mold 2 on the upper end of the grooved panel 102 of the combined steel mold 1, and paste double-sided adhesive tape on the junction of the templates. W...

Abstract

The invention provides a steel-wood combined template system for a water concrete arc-branch-shaped beam-column joint and a construction method of the template system. The template system comprises a column jacking arc section combined steel mold which is fixedly connected with a base, four circular arc steel molds and four angle steel molds III. The base is a column body steel template, and connected with a vertical column in a sealed buckling mode. Each circular arc steel mold, beam side wood-plastic templates on the axial two sides and adjacent two angle steel molds III are spliced together to reserve a cross beam joint. The construction method of the template system comprises the steps of construction preparation, template splicing, concrete pouring, template dismounting and the like. The templates are easy to splice and convenient to adjust and correct, therefore the operation difficulty of workers and safety hazards are reduced greatly, and the phenomena of mold expansion and mortar leakage of abutted seams in the slurry casting process are avoided.

Description

technical field [0001] The invention relates to the field of structural engineering, in particular to a steel-wood combined formwork system and a construction method for fair-faced concrete arc-shaped branch-shaped beam-column joints. Background technique [0002] With the spread of cutting-edge design concepts, it has become a trend for public buildings to pursue artistic aesthetic effects as much as possible on the basis of satisfying their use functions. [0003] The arc-shaped branch-like beam-column nodes have smooth lines and a great sense of shape. It can be applied in public works such as canopy and gazebo. However, the shape of the arc-shaped branch-like beam-column joints is complicated, the inner corners alternate with each other, and the formwork at the joints needs to be assembled at high altitude. In the prior art, a pure steel formwork system is usually used, and the effect of the finished product is difficult to control. There are also problems such as hea...
