Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to the construction of concrete cushion layers, specifically a crack prevention device for concrete cushion layers around frame columns. Background Technology

[0002] In construction engineering, the interior concrete subbase is an essential component. Its main functions include leveling the base layer, isolating moisture, increasing the building's load-bearing capacity, improving ground hardness, and enhancing the indoor environment, providing better support and protection for the building. Concrete is a compressive component, with the highest compressive strength and the lowest tensile strength. During later use, concrete subbases are prone to cracking. To prevent cracking, steel reinforcement is typically added to the concrete subbase to reduce crack formation, and slits are cut at 3-5m intervals, with a depth of about one-third of the concrete thickness and a width of 5-10mm. However, due to mechanical limitations, it is difficult to control the slits at the column base and column root areas, and manual slit cutting is costly. Therefore, irregular micro-cracks easily occur at the column base and column root areas, resulting in poor appearance quality of the concrete subbase and surface layer. Summary of the Invention

[0003] The purpose of this invention is to solve the problem that micro-cracks easily occur in the concrete pad and surface layer at the column base and column root of the frame column, which affects the appearance of the building and the construction quality. Therefore, this invention provides a crack prevention device for the concrete pad around the frame column.

[0004] This utility model is achieved through the following technical solution:

[0005] A crack-prevention device for the concrete pad layer around a frame column includes an overall fixing part, a column base fixing part, and a column foot fixing part. The overall fixing part includes a square frame, the height of each side of the square frame is consistent with the thickness of the concrete pad layer, and the thickness of each side of the square frame is consistent with the width of the cut in the concrete pad layer. The column base fixing part includes four first vertical straight plates, which are respectively vertically fixed at the middle position of the inner side of each side of the square frame, and the inner ends of the four first vertical straight plates form four abutment points for abutting the column base. The column foot fixing part includes four second vertical straight plates, which are respectively fixed between adjacent frame sides at four right angles in the square frame. A third vertical straight plate is vertically fixed at the middle position of the inner side of each second vertical straight plate, and a right-angled V-shaped plate is fixed at the inner end of each third vertical straight plate. The four right-angled V-shaped plates form four locking points for securing the column foot.

[0006] Furthermore, the heights of the first vertical straight plate, the second vertical straight plate, the third vertical straight plate, and the right-angled V-shaped plate are all consistent with the thickness of the concrete cushion layer, and the thicknesses of the first vertical straight plate, the second vertical straight plate, the third vertical straight plate, and the right-angled V-shaped plate are all consistent with the width of the cut joint on the concrete cushion layer.

[0007] Furthermore, the position of the first vertical straight plate coincides with the center line of the square frame, and the position of the third vertical straight plate coincides with the diagonal of the square frame.

[0008] Furthermore, fixing holes are provided at the middle and both sides of each frame edge of the square frame. A connecting protrusion is provided at one end of the first vertical plate that is fixed to the frame edge, and the connecting protrusion is snapped into the fixing hole located at the middle position on the frame edge. Both ends of the second vertical plate that are fixed to the frame edge are provided with connecting protrusions, and the connecting protrusions are snapped into the fixing holes located at the two sides on the frame edge.

[0009] Furthermore, the overall fixing part is made of thermosetting plastic (PPS) in one piece, the column root fixing part is made of thermosetting plastic (PPS) in one piece, and the column foot fixing part is made of thermosetting plastic (PPS) in one piece.
