[0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roof engineering construction, decoration engineering construction, etc. In modern building construction, the formwork and wooden blocks are often used to support the formwork of rectangular cast-in-place concrete columns. Although this method is convenient and fast, the space at the column foot after support is small. When using formwork and wooden blocks to support the formwork of rectangular cast-in-place concrete columns, it is often necessary to use tension screws to reinforce the column foot. At this time, it is easy to cause the tension screws to be difficult to install or installed loosely due to the small space at the column foot in the subsequent construction process, resulting in quality defects such as mold expansion and deformation at the column foot, which reduces the construction speed and causes certain inconveniences to the on-site construction.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-3 As shown, a column base reinforcement device for a rectangular cast-in-place concrete column includes a column base frame, which is the main structure of the device and can form a good reinforcement effect on the column base of the rectangular cast-in-place concrete column. It also includes a tensioning assembly, which includes reinforced angle steel seats 1 arranged at the four corners of the column base frame, and one side of each group of reinforced angle steel seats 1 is welded and fixed with a connecting bolt 3 that movably penetrates the column base frame, and a limiting nut 4 is arranged on the outer side of each group of connecting bolts 3.

[0020] In this embodiment, specifically, the column base frame includes four groups of fixed connectors 2, one end of each group of fixed connectors 2 is welded and fixed to the other side of a group of reinforced angle steel seats 1, and the fixed connectors 2 are of the same width as the reinforced angle steel seats 1, ensuring that a firm fixation can be formed between the two, ensuring that the fixed connectors 2 have good strength when in use.

[0021] In this embodiment, specifically, the connecting bolt 3 is welded and fixed to the external center position of one side of the reinforced angle steel seat 1, and the fixed connecting member 2 is welded and fixed to the external center position of the other side of the reinforced angle steel seat 1. The fixed connecting member 2 and the connecting bolt 3 are distributed at adjacent angles, thereby facilitating the fixation between the fixed connecting member 2 and the connecting bolt 3 on the same side.

[0022] In the present embodiment, specifically, a plurality of groups of bolt holes 6 are formed at intervals on the other end of the fixed connector 2, and the connecting bolts 3 pass through the bolt holes 6 formed at the end of the fixed connector 2. The tensioning components are arranged head to tail and a fixed connection is formed by a limiting nut 4. The connecting bolts 3 and the limiting nuts 4 cooperate with each other to form a detachable fixing structure for the fixed connector 2, which is convenient for early assembly and also convenient for disassembly after the entire construction is completed. It can be reused in subsequent construction processes, thereby reducing the cost of use.

[0023] In this embodiment, specifically, an anti-skid washer 5 is provided on the outer side of the connecting bolt 3, and the anti-skid washer 5 is located between the fixed connector 2 and the limiting nut 4. The provision of the anti-skid washer 5 further increases the contact area between the limiting nut 4 and the fixed connector 2, thereby ensuring that the surface of the fixed connector 2 is not scratched by the limiting nut 4, and dispersing the pressure of the limiting nut 4 on the fixed connector 2, thereby further improving the fixing effect of the limiting nut 4 on the fixed connector 2.

[0024] In the present embodiment, specifically, the materials of the reinforced angle steel seat 1, the fixed connector 2, the connecting bolts 3, the limit nuts 4, and the anti-slip washers 5 are all galvanized steel. The galvanized steel is covered with a layer of zinc on the surface of the steel. This layer of zinc can effectively resist the erosion of oxygen, water vapor and other corrosive substances in the atmosphere, prevent the steel from rusting, corroding and decaying, thereby significantly extending the service life of the steel. In addition, the cathodic protection effect of zinc can further protect the surface of the steel, making it less susceptible to corrosion, further extending the service life of the device.

[0025] The working principle of the utility model: when the device is in use, after the fixed connector 2 and the connecting bolt 3 are welded to the reinforced angle steel seat 1, the connecting bolt 3 on one group of reinforced angle steel seats 1 is then inserted through one end of the fixed connector 2 set on another group of reinforced angle steel seats 1 on the same side, and so on. The four groups of tensioning components are arranged end to end to form a column foot frame, which can form a good reinforcement effect on the column foot of the rectangular cast-in-place concrete column. The fixing position of the connecting bolt 3 can be changed through the bolt hole 6 opened on the fixed connector 2, and the staff can adjust the overall size of the column foot frame according to the size of the column foot of the rectangular cast-in-place concrete column.

[0026] In the description of the present invention, it should be understood that the terms "up", "down", "left", "right", "front", "back", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, and a specific direction structure and operation. Therefore, it should not be understood as a limitation on the present invention.

[0027] In addition, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
