[0002] With the objective demand for green buildings, the continuous improvement of people's environmental awareness, and the popularization of the idea of ​​returning to nature, fair-faced concrete projects have been more and more widely used in industrial buildings.

[0003] Fair-faced concrete is cast in one step without any external decoration. The natural surface effect of cast-in-place concrete is directly used as the finishing surface. The surface is flat and smooth, uniform in color, with sharp edges and corners, and no damage or pollution. The surface does not require secondary decoration, which reduces decoration costs and is energy-saving and environmentally friendly. During construction, due to the uneven casting surface and deformation at the joints of column sections in traditional construction methods, the column sections are missing edges and corners, and the column foot has leakage and roughness after the upper layer is poured. These common quality problems require secondary repairs to improve, affecting construction efficiency. In view of this, we propose a construction device to ensure the construction process quality of fair-faced concrete column head joints. Utility Model Content

[0024] A construction device for ensuring the construction process quality of the joint of a clear-faced concrete column head comprises four glued formworks 1 connected end to end, and the four glued formworks 1 form a rectangular structure, the inner walls of the four glued formworks 1 and the positions near the top are detachably connected with square wood strips 2, and the four square wood strips 2 are connected end to end to form a rectangular structure, and the square wood strips 2 are lined around the column section to ensure that the column head structure size is accurate and the force position of the steel bars is correct, while reducing the easy human damage to the column head corners and surface layer during the removal of the glued formwork 1 and the subsequent upper structure construction. The column head surface structure size is accurate and the surface is flat, so that the upper formwork of the column section is installed and the joint surface of the lower column head is tightly fastened, thereby avoiding the loose gap of the column foot formwork, and solving the quality defects such as leakage and rough surface during concrete pouring.

[0025] The outer sides of the four glued templates 1 are bonded with a plurality of steel pipes 3 arranged at equal intervals, and the steel pipes 3 are arranged vertically.

The first C-shaped reinforcement channel steel 4 and the second C-shaped reinforcement channel steel 5 are arranged horizontally, and the first C-shaped reinforcement channel steel 4 at the front and the second C-shaped reinforcement channel steel 5 at the rear are connected horizontally. A C-shaped reinforcing channel steel 4 is symmetrically arranged, and both ends of the two first C-shaped reinforcing channel steels 4 located on the same horizontal plane are fixed by tension bolts 8, which squeeze the front and rear steel pipes 3, thereby squeezing and fixing the front and rear glued formworks 1, and the second C-shaped reinforcing channel steel 5 located on the left and the second C-shaped reinforcing channel steel 5 located on the right are symmetrically arranged, and both ends of the two second C-shaped reinforcing channel steels 5 located on the same horizontal plane are fixed by tension bolts 8, which squeeze the left and right steel pipes 3, thereby squeezing and fixing the left and right glued formworks 1, thereby making the joints of the four glued formworks 1 tightly connected to avoid concrete leakage.

[0026] In this embodiment, the cross section of the square wood strip 2 is a regular rectangular structure, and the side length of the end of the square wood strip 2 is 40 mm, which avoids the size of the frame-shaped demoulding groove 70 being too large or too small, and is conducive to close docking with the upper column head.
