[0026] Reference Figure 1-2 5. This embodiment provides a foundation bolt fixture for a steel structure column, which includes a connecting plate 100, a positioning ring plate 200 and an embedded rod 300. The connecting plate 100 is arranged below the positioning ring plate 200 and in the same direction as the plate surface of the positioning ring plate 200. There are several groups of embedded rods 300 evenly distributed in the circumference of the positioning ring plate 200. The other end of each embedded rod 300 passes through the connecting plate 100 and is locked. The connecting plates 100 and the embedded rods 300 are consistent in number and corresponding in position. When the fixture is embedded in the bottom foundation of the steel structure column, the embedded rod 300 and the connecting plate 100 are extended into the steel cage (or steel mesh) in the foundation, the connecting plate 100 and the steel cage (or steel mesh) are fixed by binding, welding or other methods, and the positioning ring plate 200 is fixed to the top of the steel cage (or steel mesh) by traditional methods.

[0027] Compared with the prior art, the two ends of the embedded rod 300 can be effectively fixed to prevent the bottom end of the embedded rod 300 from being flexibly inserted into the steel cage (or steel mesh), and being disturbed and skewed when pouring concrete on the foundation, thereby reducing the problem of subsequent failure to connect the steel structure columns and rework, improving the quality pass rate of one-time construction, reducing the manpower and material resources consumed in rework, ensuring smooth construction, and avoiding delays in the construction period. Compared with the method of directly tying and welding the embedded rod 300 to the steel cage (or steel mesh), the provision of the connecting plate 100 can effectively increase the contact area between the lower part of the tooling and the steel cage (or steel mesh), increase the fixing points, and improve the connection stability with the steel cage (or steel mesh).

[0028] The above-mentioned embedded rod 300 includes a screw 310, a positioning bolt 320 and a sleeve 330, and the sleeve 330 is located between the positioning ring plate 200 and the connecting plate 100; the screw 310 is located below the sleeve 330, and it passes through the connecting plate 100 and is screwed to the sleeve 330; the positioning bolt 320 is located above the sleeve 330, and it passes through the positioning ring plate 200 and is screwed to the sleeve 330. Compared with the integrally formed anchor bolts, the screw rod 310 in the present tooling is shorter, which is convenient for insertion and displacement, and a detachable embedded rod 300 structure is adopted to improve the fixing efficiency of the embedded rod 300 and the connecting plate 100 in the steel cage (or steel mesh) of the foundation; in addition, the above-mentioned screw rod 310, positioning bolt 320 and sleeve 330 can all be prefabricated in batches in a standardized manner, and then the depth of the screw rod 310 and the positioning bolt 320 inserted into the sleeve 330 can be adjusted according to the anchor bolt length required for different construction sites, thereby changing the total length of the embedded rod 300.

[0029] During implementation, the through hole of the screw rod 310 on the connecting plate 100 can be a smooth hole, and a limiting bolt 340 is provided below the connecting plate 100. The limiting bolt 340 is sleeved on the screw rod 310, and the limiting bolt 340 is abutted against the bottom surface of the connecting plate 100. The screw rod 310 is limited by the limiting bolt 340 and the sleeve 330 on both sides of the connecting plate 100 to prevent it from shaking or deflecting.

[0030] In the above scheme, since the limiting bolt 340 and the sleeve 330 need to be pressed against the connecting plate 100 to ensure the connection stability between the screw rod 310 and the connecting plate 100, the total length of the embedded rod 300 can only be adjusted by changing the length of the positioning bolt 320 extending into the sleeve 330. This scheme is reasonable and feasible, but it is necessary to ensure that the length of the overlapping part of the positioning bolt 320 and the sleeve 330 is reasonable. If the length of the overlapping part is too short, the shear resistance of the embedded rod 300 will be reduced, which will limit the length adjustment range of the embedded rod 300 to a smaller area. Therefore, in addition to the above scheme, a limiting bolt 350 can also be set above the connecting plate 100. Refer to the attached Figure 4 The limiting bolt 350 is sleeved on the screw rod 310, and the limiting bolt 350 is abutted against the top surface of the connecting plate 100, so that the limiting bolt 340 and the limiting bolt 350 can be used to limit the screw rod 310, and the length of the top end of the screw rod 310 extending into the sleeve 330 can be adjusted, which greatly increases the length adjustment range of the embedded rod 300 and increases the use range of the tooling.

[0031] Of course, the through hole of the screw rod 310 on the connecting plate 100 can also be a threaded hole 110, and the threaded hole 110 is adapted to the thread of the screw rod 310. In this way, the length of the top of the screw rod 310 extending into the sleeve 330 can also be adjusted. On this basis, the limiting bolt 1 340 and the limiting bolt 2 350 arranged as in the above scheme can be added to increase the connection stability between the screw rod 310 and the connecting plate 100.

[0032] During implementation, the through hole of the positioning bolt 320 on the positioning ring plate 200 is a threaded hole 210 (see attached Figure 3 ), the threaded hole 210 is adapted to the thread of the positioning bolt 320, and the threaded hole 110 limits the positioning bolt 320, so as to realize the stable connection between the positioning ring plate 200 and the positioning bolt 320. The positioning ring plate 200 also serves as the structure of the tooling to connect the steel structure column, and it can be fixed to the steel structure column by welding, bolt connection, etc.

[0033] The above-mentioned sleeve 330 can be configured to be hollow throughout, and a thread that is compatible with the screw 310 and the positioning bolt 320 can be set on the inner wall. If the size and thread of the screw 310 and the positioning bolt 320 are consistent, the thread on the inner wall of the sleeve 330 can be a continuous, fixed-size thread; if the size and thread of the screw 310 and the positioning bolt 320 are inconsistent, the thread on the inner wall of the sleeve 330 needs to be divided into two sizes, which are respectively compatible with the screw 310 and the positioning bolt 320.

[0034] Of course, the sleeve 330 can also be configured to be dense in the middle and have a thread groove 1 331 and a thread groove 2 332 at both ends (see attached Figure 6 ), the thread groove 1 331 is adapted to the thread of the screw rod 310, and the thread groove 2 332 is adapted to the thread of the positioning bolt 320. The dense middle part of the sleeve 330 can improve the bending resistance of the sleeve 330, and the thread groove 1 331 and the thread groove 2 332 can also be the same thread or different threads according to the above configuration.

[0035] Compared with the prior art, the beneficial effects of the present invention are as follows: the lower part of the tool is fixed to the steel cage (or steel mesh) in the foundation by the connecting plate 100, so as to prevent the embedded rod 300 from being skewed due to the disturbance of the foundation pouring concrete, avoid rework, reduce construction costs, and ensure the construction period; through the detachable and adjustable embedded rod 300, the construction convenience and adjustability of the tool are improved, so that it can be used in a variety of construction standards when it is achieved in quantitative and batch prefabrication.

[0036] The above are preferred implementations of the present utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications should also be regarded as the protection scope of the present utility model.
