Abstract
Description
Technical Field
[0001] The utility model relates to a deformation joint template construction tool, in particular to a double-column structure deformation joint template structure and template reinforcement tool. Background Art
[0002] Currently, in most frame structures with large footprints and long lengths, such as factories and shopping malls, expansion joints are required along a certain length to prevent uneven structural settlement or internal deformation caused by concrete shrinkage due to temperature fluctuations. Independent load-bearing systems exist on either side of the expansion joint, creating a "double-column" structure. However, the narrow expansion joints present certain difficulties during construction.
[0003] In traditional construction, the first method is to fill the deformation joints of the double columns with polystyrene boards before the double-column structure is assembled, and use wooden formwork to install the formwork on the outside. When pouring concrete, the double-column structure is poured and constructed in layers simultaneously.
[0004] During construction, this method has problems with the thickness of the polystyrene board filled in the middle structural joint of the "double columns" and the designed gap width. The filled polystyrene board is cut according to the column size, and the two polystyrene boards are assembled and pasted. The stiffness of the joints and the boards themselves are not met. When pouring concrete, the lateral pressure causes the polystyrene board to deform, and it is very easy for the polystyrene board to tilt to one side. The joints are prone to squeezing and spreading. The concrete components have quality problems such as local necking, bulging and local cross-sections, resulting in large deviations in the "double column" structure at the deformation joint, not straightness, exposed reinforcement, and difficulty in removal when removing the formwork. At the same time, when the tension bolts or the formwork are installed, the polystyrene board will drop particles and is not easy to clean, resulting in slag inclusions at the column roots.
[0005] The second method is: first set up a single column formwork separately, after the single column structure is constructed and the formwork is removed, then set up the formwork of another column for construction.
[0006] This method involves constructing the structural columns on both sides separately. Since the construction cannot be carried out synchronously, the construction efficiency is low and the construction progress is slow, which can easily disrupt the flow construction deployment of the entire unit project.

[0027] A plurality of bolt holes are provided on the first side plate 1-8 along the length direction of the main body 1-1, and support bolts 1-2 are inserted into the bolt holes. The support bolts 1-2 are perpendicular to the first side plate 1-8 and pass into the bolt holes from the outside of the first side plate 1-8. A support pad 1-5 is provided at the outer end of the adjusting nut 1-3, and the distance between the support pad 1-5 and the second side plate 1-9 is controlled by adjusting the protruding length of the support bolts 1-2.
[0028] An adjusting nut 1-3 is threadedly connected to the supporting bolt 1-2, and the adjusting nut 1-3 is located on the outside of the first side plate 1-8. Rotating the adjusting nut 1-3 can control the extension length of the adjusting nut 1-3, so that the outer end of the adjusting nut 1-3 is pressed against the supporting pad 1-5, and the template 3 is pressed by the supporting pad 1-5 to position and fix the template 3.
[0029] There are at least two supporting bolts 1-2 and they are evenly distributed along the length direction of the body 1-1.

The body 1-1 includes a first side panel 1-8, a second side panel 1-9, and a bottom panel 1-10. The body 1-1 has a U-shaped cross-section. Several support bolts 1-2 are distributed along the length of the body 1-1 on the first side panel 1-8.
