Description

Technical Field

[0001] The utility model relates to the field of steel structure construction, in particular to an auxiliary device for three-dimensional spatial posture control of steel structure installation. Background Art

[0002] In recent years, the number of steel structure buildings has gradually increased. The accuracy of measurement directly affects the quality of the project and is an important indicator for measuring the quality of steel structure projects. Large-scale steel structure buildings generally have the characteristics of large scale and complex shape, so the measurement and control of splicing and installation is particularly important. Due to the special properties of steel components, they will deform during the lifting process, and the high-altitude docking points make it difficult for conventional instruments to complete the measurement task, or the measurement is difficult or the accuracy cannot be guaranteed. In order to ensure the accuracy of installation and splicing and improve the efficiency of measurement, the digital model measurement and control technology will be fully implemented in the measurement work to provide a control basis for construction quality. The precise control of the three-dimensional posture of steel structure installation components will also become the mainstream research direction in the industry.

[0003] During the construction of the steel structure workshop, the vertical steel columns are connected to the horizontal steel beams, and the frame body is connected by riveting + welding. The traditional steel beam components are hoisted to the estimated position by a crane and prepared to be connected with the steel columns. The plane position is often controlled by manual visual inspection. The surveyors observe and direct on the ground, and the auxiliary personnel climb on the working aerial platform to adjust the posture of the swing components so that they are close to being perpendicular to the steel columns and at the center axis of the two columns. In terms of elevation control, the auxiliary personnel stand at both ends of the top of the steel beam with a tower ruler. After the surveyors observe that the elevation of the components meets the requirements, they can pre-anchor the components to change from the free state during the hoisting process to a stable state. This operation mode has problems such as poor operation efficiency, poor installation quality, and high safety risks. After improvement, a three-dimensional attitude control measurement method of total station control of plane position + laser level control of installation elevation is adopted to ensure the accurate installation of steel components. In the process of using a laser level to control the installation elevation, the laser level needs to be used at different heights following the steel beam. The placement of the laser level is a difficult point, and the prior art lacks the technology for placing and using the laser level at different heights. Utility Model Content

[0004] The utility model aims to provide an auxiliary device for three-dimensional spatial posture control of steel structure installation, so as to solve the problem that the prior art lacks the technology of placing and using laser level instruments at different heights.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an auxiliary device for three-dimensional spatial posture control of steel structure installation, including an L-shaped plate-shaped mounting seat, the vertical plate of the mounting seat is a connecting plate, and a plurality of connecting points are arranged on the connecting plate, and the connecting points are used to connect the mounting seat to the side end of the steel column, and the horizontal plate of the mounting seat is a placing plate, and three mounting grooves evenly distributed in a ring shape are arranged on the placing plate, and the mounting grooves are used to place a laser level.

[0006] Preferably, as an improvement, the connection point is a plurality of support plates integrally formed at the side ends of the connection plates, the support plates extend out of the connection plates, and the support plates are welded to the steel columns.

[0007] Preferably, as an improvement, the connection point is a welding point arranged on the side of the connection plate.

[0008] Preferably, as an improvement, the connection point is a plurality of screw rods which are transversely threadedly connected to the connection plate, and the screw rods are welded to the steel column.

[0009] Preferably, as an improvement, the mounting groove is a circular flat-bottomed groove.

[0010] Preferably, as an improvement, the mounting groove is a conical groove.

[0011] The principle and advantages of this scheme are: in actual application, the process of three-dimensional spatial posture control during the installation of steel structures includes taking advantage of the fact that the installation position of a single-layer steel beam is at the same elevation. 20 cm below the connection point between the steel beam and the steel column, the auxiliary device of this scheme is welded and fixed on the steel column, and a laser level is placed on it. The installation groove provides a placement position for the laser level to prevent the laser level from slipping from the placement position or being hit by external forces. The plane control network established by the laser level makes the bottom edge of the steel beam coincide with the laser line as a control indicator, which can effectively control the installation height of the steel beam. One can be arranged on each of the four corner steel columns of the building for encryption to improve the installation accuracy. As the number of installation layers increases, the laser level will follow up synchronously. Taking advantage of the fact that the total station can measure the plane position, the plane position of the steel beam is controlled. Through the effective combination of the laser level + total station, the installation elevation and plane installation position of the steel component are accurately controlled to form an efficient operation mode, which ensures the one-time installation qualification rate of the component and improves the operation efficiency. The placement of the laser level is completed through the auxiliary device of this solution. The three legs of the laser level are positioned and limited through the installation groove, so it is not easy to fall even if it is accidentally hit. The connecting plate can be directly welded to the steel column, or it can be welded to the steel column through the support plate, or it can be welded to the steel column through the screw. After use, it can be removed by cutting off the welding point. The support plate and the screw are located outside the connecting plate to reduce the damage to the connecting plate during the cutting process, so that the mounting base can be reused. The screw method can increase the number of uses of the mounting base by replacing the screw, which is conducive to reducing construction costs and improving construction efficiency.

[0015] The following is further described in detail through specific implementation methods:

[0016] The reference numerals in the drawings of the specification include: steel column 1, connecting plate 2, mounting plate 3, mounting groove 4, support plate 5, screw rod 6.

[0017] Embodiment 1, basically as attached Figure 1 As shown: The auxiliary device for three-dimensional spatial posture control of steel structure installation includes an L-shaped plate-shaped mounting seat, the vertical plate of the mounting seat is a connecting plate 2, and a plurality of connecting points are arranged on the connecting plate 2, and the connecting points are used to connect the mounting seat to the side end of the steel column 1, and the connecting points are welding points arranged on the side of the connecting plate 2. The horizontal plate of the mounting seat is a placement plate 3, and the placement plate 3 is provided with three mounting grooves 4 evenly distributed in an annular shape, and the mounting grooves 4 are used to place the laser level, and the mounting grooves 4 are circular flat bottom grooves.

[0018] Embodiment 2, as Figure 2 As shown, the difference between this embodiment and embodiment 1 is that the connection point is six support plates 5 integrally formed at the side end of the connecting plate 2, and the support plates 5 extend out of the connecting plate 2. When in use, the support plates 5 are welded to the steel column 1. The support plates 5 are used as the extended welding structure, and the mounting seat can be removed by cutting off the support plates 5 after completing the installation and positioning of the steel structure. Only the welding part can be cut off, and the remaining support plates 5 make the mounting seat reusable. The extended support plates 5 are also easier to cut, which is conducive to reducing the cut marks on the steel column 1 during cutting, and avoiding affecting the structural performance of the steel column 1.

[0019] Embodiment 3, as Figure 3As shown, the difference between this embodiment and embodiment 1 is that the connection point is three screws 6 connected to the connecting plate 2 with transverse threads, and the three screws 6 are evenly distributed with one on the top and two on the bottom. When in use, the screw 6 is adjusted to pass through the connecting plate 2 to be consistent, and then the screw 6 is welded to the steel column 1. The screw 6 is used as an extended welding structure. When in use, the length of the screw 6 passing through the connecting plate 2 is first adjusted to be consistent, and then the end of the screw 6 is spot-welded to the steel column 1. The extended length space is also convenient for welding operation. After the steel structure is installed, it is also convenient for cutting operation. It only needs to cut off the welding part at the end of the screw 6. It will not cause structural damage to the connecting plate 2 and the steel column 1. The welding and cutting operations are convenient and efficient. And it can be reused after dismantling. It only needs to adjust the length of the screw 6 passing through the connecting plate 2 to be consistent. The mounting seat can be reused, and only the screw 6 needs to be consumed, which is conducive to reducing costs.

[0020] Embodiment 4: The difference between this embodiment and embodiment 1, embodiment 2 or embodiment 3 is that the mounting groove 4 is a conical groove. The conical groove is more in line with the shape of the conical support foot of the laser level, and the limiting and positioning of the laser level is more stable and reliable.

[0021] The specific implementation process is as follows: The process of three-dimensional spatial posture control during the steel structure installation process includes utilizing the characteristics that the installation position of the single-layer steel beam is at the same elevation. 20 cm below the connection point between the steel beam and the steel column 1, the auxiliary device of this scheme is welded and fixed on the steel column 1, and a laser level is placed on it. The installation slot 4 provides a placement position for the laser level to prevent the laser level from slipping from the placement position or being hit by external forces.

One can be arranged on each of the four corner steel columns 1 of the building for encryption to improve the installation accuracy. As the number of installation layers increases, the laser level will follow up synchronously. Utilizing the characteristics of the total station that can perform plane position measurement, the plane position of the steel beam is controlled. Through the effective combination of the laser level + total station, the installation elevation and plane installation position of the steel component are accurately controlled to form an efficient operation mode, ensuring the one-time installation pass rate of the component and improving the operation efficiency. The placement of the laser level is completed through the auxiliary device of the utility model. The installation groove 4 provides positioning and limiting for the three legs of the laser level. Even if it is accidentally hit, it is not easy to fall. The connecting plate 2 can be directly welded to the steel column 1, or it can be welded to the steel column 1 through the support plate 5, and it can also be welded to the steel column 1 through the screw 6. After use, it can be removed by cutting off the welding point. The support plate 5 and the screw 6 are located outside the connecting plate 2 to reduce the damage to the connecting plate 2 during the cutting process, so that the mounting seat can be reused. The screw 6 method can increase the number of uses of the mounting seat by replacing the screw 6, which is beneficial to reducing construction costs and improving construction efficiency.
