[0002] With the continuous development of the construction industry, the requirements for structural seismic resistance are becoming increasingly higher; structural columns, as an important part connecting the masonry infill wall and the main structure, can effectively improve the bonding effect, overall stability and rigidity between the masonry and the main body, and play an increasingly important role in the construction field.

[0003] At present, when formwork is performed on the structural columns in the infill wall, the formwork templates are made at the construction site and the formwork is performed after the production is completed, and the support system and reinforcement system are installed at the same time; however, when formwork is performed on the structural columns in the outer wall area of the infill wall structure that are exposed to air on one side, since one side of the wall is exposed to air, the workers have to perform the formwork operation at high altitude during the formwork operation, and the outer formwork lacks corresponding support relative to the inner formwork, which easily causes the inner and outer formworks to be unable to be accurately aligned, affecting the subsequent formwork work and reducing construction efficiency. Summary of the Invention

[0006] The beneficial effects are: the installation position of the bottom bracket is fixed by connecting it to the infill wall, the outer formwork is connected to the bottom bracket by opening a limit groove on the bottom bracket, and then the outer formwork is connected to the inner formwork by tension bolts to cast the structural column; when the staff installs the outer formwork, the bottom bracket is installed on the infill wall, and then the outer formwork is installed in the limit groove to complete the installation of the outer formwork, reducing the time spent by the staff to fix the outer formwork, thereby improving construction efficiency; at the same time, since the time spent on installing the outer formwork is reduced, the time spent by the staff at high altitude is reduced, and the risks brought by high altitude work are reduced.

[0007] A further technical solution of the present invention is that the filling wall is provided with mounting plates at both ends of the base in the length direction, the mounting plates are connected to the filling wall, the mounting plates are provided with mounting grooves along the length direction, the mounting grooves pass through the mounting plates, and both ends of the base in the length direction are installed in the mounting grooves.

[0008] The beneficial effect is: by opening an installation groove on the installation plate, the base bracket can be installed quickly. At the same time, the installation plate also provides an installation limit for the base bracket, so that the base bracket can be accurately installed on the filling wall through the installation plate, thereby improving the installation accuracy of the outer template.

[0009] A further technical solution of the present invention is that avoidance grooves are provided at both ends of the base in the length direction, the size of the avoidance grooves matches the size from the side wall of the installation groove to the filling wall, and the base is installed in the installation groove at the places where the avoidance grooves are provided at both ends of the length direction.

[0013] A further technical solution of the present invention is that the inner template is provided with a waist-shaped hole at the position where the tension bolt passes through, and square wood is arranged at the inner template and the waist-shaped hole, and the size of the square wood is larger than the size of the waist-shaped hole.

[0014] The beneficial effect is: when the inner formwork is installed after the outer formwork is installed, the waist-shaped hole can reduce the installation deviation of the inner and outer formworks, and adjustment is made through the waist-shaped hole to facilitate the installation of the connecting bolts and the installation of the inner and outer formworks; and the square wood seals the waist-shaped hole, reducing the probability of leakage from the waist-shaped hole during the pouring process.

[0015] A further technical solution of the present invention is that the outer template and the bottom support are both made of metal.

[0016] The beneficial effect is that since the structural columns of the infill wall are cast layer by layer, the outer formwork and the base are made of metal material so that the outer formwork and the base can be used multiple times, reducing the material cost of making the formwork during the construction process.

[0017] A further technical solution of the present invention is that sleeves are provided between the tension bolts between the outer template and the two inner templates, and between the two inner templates.

[0018] The beneficial effect is that the sleeve is provided so that the tension bolts can be taken out of the sleeve after the structural column is cast, so that the tension bolts can be reused.

[0019] A further technical solution of the present invention is that the filling wall is provided with tooth-shaped ridges at the structural columns, and the filling wall is provided with sponge strips along the edges of the tooth-shaped ridges.

[0020] The beneficial effects are: the tightness of the connection between the structural column and the infill wall is enhanced by rubbing with horse teeth, thereby improving the earthquake resistance of the entire building; the sealing effect of the sponge strips reduces the leakage of concrete from the gap between the formwork and the wall, thereby avoiding defects such as honeycomb and roughness on the concrete surface, and improving the appearance quality and overall performance of the structural column.
