Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a positioning and vertical adjustment device for a structural column. Background Art

[0002] As the utilization rate of urban space becomes higher and higher, the edge of the main building is getting closer and closer to the red line range, and the actual construction site area is getting smaller and smaller in the later stage. For example, there is no operating surface for excavation equipment and earthwork transportation vehicles when constructing according to the forward method. In addition, the depth of the foundation pit is getting deeper and deeper, resulting in a longer and longer construction period for the underground structure. There are many original buildings and pipelines around, and the overall safety requirements for the foundation pit are high. In order to realize the economic value of the building as soon as possible and shorten the construction project of the basement structure. The reverse construction method is now mostly used to construct the basement, which can effectively control the uncertain danger caused by deformation of the foundation pit and shorten the construction period. When the reverse construction method is used, the structural column construction can no longer be carried out after the excavation is completed. The structural column construction must be carried out before the excavation. Now generally single pile and single column, pile middle and lower steel lattice column or steel pipe column is used. Because it is a subsequent permanent force-bearing structure, when installing the steel column, the verticality requirement is very high. Generally, the accuracy required is 1 / 500 to 1 / 800, which is much higher than the original temporary lattice column requirement. The requirements for installing lattice columns are getting higher and higher. If the previous temporary lattice column vertical construction method using its own weight is still used, it can no longer meet the current requirements. Summary of the invention

DETAILED DESCRIPTION

[0033] The following is a further detailed description of a structural column positioning and vertical adjustment device proposed by the present invention in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description and claims.

[0034] See also Figure 1In one embodiment, the positioning and vertical adjustment device of the structural column includes: a base and a straightening frame. The base includes a positioning steel plate 1 and a limiter 2. A through hole is opened in the center of the upper surface of the positioning steel plate 1, and the diameter of the through hole is larger than the diameter of the structural column. The limiter 2 is arranged on the upper surface of the positioning steel plate 1. The straightening frame includes a base 13, an upper table 4, a plurality of fixed plate units 5, at least four vertical screws 6 and at least four jack support plates 7. The base 13 is arranged on the upper surface of the positioning steel plate 1 and is limited by the limiter 2. A through hole corresponding to the positioning steel plate 1 is opened in the center of the base 13. The upper table 4 is arranged on the base 13 and is connected by a plurality of reinforced steel plates. A through hole corresponding to the positioning steel plate 1 is opened in the center of the upper table 4. The fixed plate unit 5 is vertically arranged on the peripheral side of the through hole of the upper table 4. The shape of the fixed plate unit 5 matches the diameter of the structural column. The corresponding positions of the fixed plate unit 5 and the structural column are provided with corresponding fixing holes 14 and can be connected through external connectors. The vertical screw rod 6 is threadedly connected to the upper table 4 and the base 13. The upper part of the connection between the vertical screw rod 6 and the base 13 is provided with a nut threadedly connected to the vertical screw rod 6. The connecting lines between the vertical screw rods 6 form a regular polygon. The jack support plate 7 is fixedly connected to the outer edge of the upper table 4. The connecting lines between the jack support plates 7 form a regular polygon. The structural column is a steel pipe column or a lattice column. When the structural column is a steel pipe column, the fixed plate unit 5 is an arc plate; when the structural column is a lattice column, the fixed plate unit 5 is an L-shaped plate. After the fixed plate unit 5 and the structural column are fixedly connected through the fixing hole 14 by the external connecting piece, the height of the straightening frame can be increased by adjusting the vertical screw 6 and lifting the jack support plate 7 with a jack, so that the elevation of the structural column meets the requirements. A reinforcing rib plate is provided on the arc (or L-shaped) plate unit 5 to improve the bearing capacity of the arc (or L-shaped) plate unit 5, so that it can carry structural columns with larger diameters and weights. A reinforcing rib plate is provided on the jack support plate 7 to improve the bearing capacity of the jack support plate 7. The vertical screw 6 is a screw with a diameter of 50 mm, and a steel bar with a diameter of 32 mm is provided on the top of the screw to rotate the vertical screw 6. By arranging a nut at the upper part of the connection between the vertical screw 6 and the base 13, the threaded connection length of the vertical screw and the base is increased, thereby ensuring the self-locking performance of the threaded connection here. During the construction of the structural column, the positioning steel plate 1 is first positioned at the center of the pile position, and the four corners and eight points of the positioning steel plate 1 are fixed firmly with steel bars to control the pile position center control error within 10mm. Then the straightening frame is installed on the positioning steel plate 1 and limited by the limiter 2. After the structural column is installed, the arc (or L-shaped) plate unit 5 controls the center of the structural column, and the jack support plate 7 is lifted by the jack to adjust the posture of the straightening frame to control the verticality of the structural column. The vertical screw 6 controls the distance between the straightening frame and the positioning steel plate 1 to control the verticality and elevation error of the structural column. Through the coordination of the positioning steel plate 1 and the straightening frame and the setting of the vertical screw 6 and the jack support plate 7, the verticality and elevation of the structural column installation meet the design requirements.The site conditions can be optimized by setting the positioning steel plate 1, and the positioning steel plate 1 can be used to make the floor of the main area of ​​the straightening frame flat and firm.

[0035] Furthermore, the straightening frame also includes a first movable connecting frame 8, a second movable connecting frame 9, a first transverse screw 11 and a second transverse screw 10. The first movable connecting frame 8 and the second movable connecting frame 9 are respectively slidably connected to the first side and the second side of the upper table 4, and the first movable connecting frame 8 is provided with an arc (or L-shaped) plate unit 5, and the second movable connecting frame 9 is provided with an arc (or L-shaped) plate unit 5. The first transverse screw 11 is threadedly connected and penetrated on the first side of the upper table 4, and the tail end of the first transverse screw 11 is connected to the first movable connecting frame 8, and is used to control the movement of the first movable connecting frame 8. The second transverse screw 10 is threadedly connected and penetrated on the second side of the upper table 4, and the tail end of the second transverse screw 10 is connected to the second movable connecting frame 9, and is used to control the movement of the second movable connecting frame 9. The first transverse screw 11 and the second transverse screw 10 are screws with a diameter of 26 mm, and a steel bar with a diameter of 25 mm is provided on the top of the screw so as to rotate through the first transverse screw 11 and the second transverse screw 10. The movable connecting frame is provided so that the spacing between the arc-shaped (or L-shaped) plate units 5 can be varied, so as to meet the installation requirements of structural columns with different diameters. At the same time, the self-locking property of the threaded connection can be used to accurately control the positions of the first movable connecting frame 8 and the second movable connecting frame 9 to prevent the impact during the construction process from reducing the accuracy of the straightening frame.

[0036] Furthermore, the upper surface of the positioning steel plate 1 is provided with a center position scale line, and the bottom of the base 13 is provided with a center point groove corresponding to the center position scale line. By setting corresponding centering marks, the accuracy of the installation of the straightening frame and the positioning steel plate 1 is improved, and the installation error is reduced.

[0037] Furthermore, two first limiting nuts are provided on the first transverse screw 11, and two second limiting nuts are provided on the second transverse screw 10. By providing the limiting nuts, the screwing amount of the first transverse screw 11 and the second transverse screw 10 is limited.

[0038] Furthermore, the stopper 2 is an angle steel, and a reinforcing rib plate is arranged on the angle steel. By arranging the reinforcing rib plate on the angle steel, the bearing capacity of the angle steel is improved and it is not easy to deform.

[0039] Furthermore, each end of the positioning steel plate 1 is provided with a positioning steel plate hook 3, and the peripheral side of the upper table 4 is provided with a straightening frame hook 12. By providing the positioning steel plate hook 3 and the straightening frame hook 12, it is convenient to carry the positioning steel plate 1 and the straightening frame at the construction site.
