[0026] Reference Figure 1-Figure 2 The utility model provides a guide device for installing a steel column in a pile, comprising:
[0027] H-shaped steel 2, two H-shaped steels 2 are arranged side by side, and the bottom surfaces of the two H-shaped steels 2 are in contact with the top of the casing 7; the H-shaped steel 2 is calculated according to the weight of the steel column 4, and the length of the H-shaped steel 2 matches the size of the casing 7, so that the H-shaped steel 2 has sufficient rigidity to ensure that it can bear the weight of the steel column 4 without deformation. The two sections of H-shaped steel 2 are of the same model and size;
[0028] Angle steel 3, there are four angle steels 3, four angle steels 3 are symmetrically welded on the opposite end faces of the two H-shaped steels 2, and steel columns 4 are slidably connected between the four angle steels 3; the angle steels 3 have sufficient length and rigidity, and are connected and reinforced by a fixed plate group to form a guide groove for the steel columns 4; the four angle steels 3 have the same specifications and length; the four angle steels 3 are equidistant from the center of the H-shaped steel 2;
[0029] The fixed plate group is provided with two rows, and the two rows of fixed plate groups are installed between the two H-shaped steels 2. Each row of fixed plate groups includes a plurality of fixed plates 5 arranged at intervals from top to bottom. The fixed plates 5 are welded to the side of the angle steel 3 away from the steel column 4; the connection and reinforcement are carried out by a plurality of fixed plates 5; in this embodiment, the fixed plates 5 are made of steel plates;
[0030] Among them, the tops of the two opposite side walls of the steel column 4 are respectively welded with positioning supports 6, and the two positioning supports 6 are respectively placed on the top surfaces of the two H-shaped steels 2;
[0031] With such a configuration, the utility model forms a rectangular guide groove by enclosing four angle steels 3 and two H-shaped steels 2, which facilitates the rapid and stable installation and position control of the steel column 4, ensures the verticality of the steel column 4, and provides support for the steel column 4, solving the problem of fixing the steel column 4 before the concrete solidifies.
[0032] The utility model makes the guiding device more firm and stable as a whole by cooperating with the fixing plate 5, the angle steel 3 and the H-shaped steel 2, and the placement of the steel column 4 is also smoother, thereby improving the overall structural strength and convenience of use;
[0033] The utility model is more convenient for adjusting the direction, elevation or position of the steel column 4 when it is placed and after the installation is completed. It is simple, fast, time-saving, labor-saving, easy to use and reusable. It ensures that the steel column 4 is in a firm and stable state in the pile hole of the casing 7, avoids secondary rework, ensures that the position of the steel column 4 in the pile is accurate and the verticality meets the requirements, provides support for the steel column, ensures construction quality and improves work efficiency.
[0034] To further optimize the solution, hanging points 1 are welded to the webs at both ends of the H-shaped steel 2.
[0035] Further optimization scheme, the casing 7 is a steel casing, and the steel casing is welded with a ground support, which is placed on the working surface steel plate;
[0036] The steel casing should be of sufficient length and have a ground support (not shown) welded to the ground contact position. It should be placed on the working surface steel plate and can withstand the load transferred by the steel column 4 without being lowered.
[0037] According to a further optimization scheme, the distance between the upper and lower adjacent fixing plates 5 is 150 mm to 250 mm. In this embodiment, the distance between the upper and lower adjacent fixing plates 5 is preferably 200 mm.
[0038] Further optimizing the solution, the top of the angle steel 3 is flush with the top surface of the H-shaped steel 2.
[0039] According to a further optimization scheme, the length of the angle steel 3 is 1.5m to 3.0m.
[0040] The utility model is manufactured according to the actual specifications and dimensions of the column installed in the pile hole and the dimensions of the steel casing. In this embodiment;
[0041] The steel column 4 has a width of 400 mm, a height of 400 mm, a length of 6 m, and a weight of 150 kg / m;
[0042] The diameter of the steel casing is 1.2m. According to design calculations, multiple ground supports need to be welded at the contact point between the steel casing and the ground so that it can bear the weight of the column without sinking, and it should be placed on the steel plate of the working surface.
[0043] After design calculation, two sections of H-shaped steel with the same size and sufficient rigidity to support the steel column 4 with a length of 1.5m are prepared, as well as four angle steels 3 with a length of 3m and sufficient rigidity. The length can be lengthened or shortened as appropriate according to the conditions of overfilling or pile top elevation.
[0044] The inner corners of the angle steel 3 and the H-beam 2 are perpendicular and inward. Based on the known 400mm size of the steel column 4, the steel columns are welded together at equidistant intervals of 200mm on either side of the center of the H-beam 2. The top of the angle steel 3 is flush with the top surface of the H-beam 2, forming a guide groove upon welding. Welding reinforcement is then performed on the periphery of all angle steels 3, starting at the point where the top of the angle steel 3 meets the top surface of the H-beam. Based on the size of the steel column 4, each 410mm long steel plate can be used. Given the 3m length of the angle steel 3, multiple steel plates are added, with weld reinforcement performed every 200mm. The steel plate specifications are determined based on design calculations.
[0045] After the reinforcement is complete, a strong and stable guide device is formed. The guide device can then be lifted using lifting point 1, and the bottom surface of the H-shaped steel 2 can be placed on top of the steel casing to lower the steel column 4. Positioning supports 6 are welded to the top of the steel column 4 according to the design data on the drawing. Positioning supports 6 are placed on the H-shaped steel 2 to lower the steel column 4 to the designed elevation. The positioning supports 6 are empirically calculated to have sufficient rigidity to withstand the load transferred by the steel column 4.
