[0002] Some school stadium construction projects have steel structure grid roofs and steel harp frames interlaced with glass curtain walls on the facades. Each harp weighs about 0.7 to 1.5 tons and is 7 to 15 meters high, with a total of 188 harps.

[0003] Each harp is in the shape of a shuttle, with an octagon in the middle and quadrilaterals at both ends. The upper end of the harp is connected to the roof in a staggered manner and arranged at a certain angle. The length of the harp components of the entire venue is required to gradually decrease from the middle to the two ends, and to be arranged in a certain arc on the facade. Due to the many angles, types and quantities, the construction is difficult.

[0004] The conventional construction plan is to first measure and lay out the lines to find out the relative distance between each hanging point and the harp rods; then purchase and process all rods, connecting plates and other materials according to the corresponding sizes; finally, use mechanical equipment to fix the upper and lower connection points of the harp to complete the installation of the harp rods. However, there are many harps in this project, many types, and there are certain deviations in the hanging points. Conventional measurement and laying out construction is difficult and takes a long time. If conventional construction plans are used, the construction period and cost are difficult to control. Summary of the invention

[0005] The present invention is made to solve the above-mentioned problems, and aims to provide a steel structure installation system that can perform spatial adjustment during installation, so as to solve the problem that there are many types and angles of hanging parts and they cannot be purchased and constructed in large quantities.

[0006] To achieve the above-mentioned purpose, the present invention proposes a steel structure installation system, which has the following characteristics: it is installed at the bottom of the roof of a building, and includes: a first number of harp hangers, a first connecting member and a second connecting member corresponding to each of the harp hangers, a fixing member corresponding to each of the second connecting members, a round tube, and a steel structure grid at the bottom of the roof, wherein the round tube is fixed below the steel structure grid, and a plurality of fixing members are sequentially installed on the round tube at a preset distance, each of the first connecting members is fixed to the corresponding fixing member, each of the second connecting members is fixed to the top of the corresponding harp hanger, and each of the first connecting members is fixed to the corresponding second connecting member, so as to form the steel structure installation system.

[0007] In addition, a steel structure installation system proposed by the present invention also has the following characteristics: the circular tube has a hanging point corresponding to each of the harp hangers, and the plurality of fixing components are sequentially installed on the circular tube according to the positions of the hanging points.

[0008] In addition, the steel structure installation system proposed by the present invention also has the following feature: the fixing member is a sleeve sleeved on the round tube.

[0009] In addition, the steel structure installation system proposed by the present invention also has the following feature: the first connecting member is a hanging ear plate fixed to the top end of the harp hanging member.

[0010] In addition, a steel structure installation system proposed by the present invention also has the following feature: the second connecting member is an upper ear plate fixed directly below the sleeve.

[0011] In addition, the steel structure installation system proposed by the present invention also has the feature that the bottom end of the harp hanger is fixed on the main structural column in the curtain wall of the building.

[0012] In addition, the present invention also provides a steel structure installation system installation method for installing the above-mentioned steel structure installation system, which has the following characteristics:

[0013] Installation of round tube: each fixing member to which the upper ear plate is fixed is installed on the preset hanging point of the round tube, and the round tube is fixed under the steel structure grid;

[0014] Connecting member installation: fixing each of the first hanging ear plate and the second hanging ear plate to the top end and the bottom end of the corresponding harp hanging member respectively;

[0015] Installation of the hanging parts: fix each of the second hanging ear plates on the main structural column in sequence, and fix the first hanging ear plate on the upper ear plate;

[0017] In addition, the steel structure installation system installation method proposed in the present invention also has the following feature: the fixing member is a sleeve sleeved on the round tube.

[0018] The steel structure installation system and installation method involved in the present invention are mainly suitable for installing a hanger structure with various rod specifications and irregular angles under a roof steel structure. Before installation, the sleeve and ear plate suitable for fixing under the steel structure grid are selected and customized according to the layout size to ensure that the deviations in the later construction are within the range that can be eliminated. In the early stage of installation, modeling is performed by model software, and the installation and fixing work of the connecting structure at both ends of the hanger is completed before the hanger leaves the factory, and the hanger is uniformly transported to the site for direct lifting. The steel structure installation system involved in the present invention can be customized once and processed in batches, which is not only low-cost, but also can effectively avoid a large number of measurements and layouts in traditional installation methods and the error rate in the measurement process, greatly shortening the construction period. Since the steel structure installation system is easy to adjust in time according to the actual installation situation during the installation process, the construction can be completed in one time after the adjustment is completed during the lifting process, which can effectively avoid rework caused by component processing errors.

[0025] The following is a detailed description of a steel structure installation system and an installation method thereof according to the present invention with reference to the accompanying drawings and embodiments. The following describes the principle and features of the present invention in conjunction with the accompanying drawings. The examples are only used to explain the present invention and are not used to limit the scope of the present invention.

[0027] Figure 2 It is a schematic diagram of the installation structure of the steel structure installation system in an embodiment of the present invention.

[0028] Figure 3 It is a schematic diagram of a partial installation structure of a steel structure installation system in an embodiment of the present invention.

[0029] To achieve the above-mentioned purpose, the present invention proposes a steel structure installation system, which is installed at the bottom of the roof of the building, including: a first number of harp hangers 1, a first connecting member 2 and a second connecting member 3 corresponding to each of the harp hangers 1, a fixing member 4 corresponding to each of the first connecting members, a round tube 5, and a steel structure grid 6 at the bottom of the roof. The above-mentioned steel structure grid 6 has been arranged on site, and the above-mentioned harp hangers 1 need to be installed on the steel structure grid 6 with high precision according to the actual size of the site. In the present invention, each harp hanger 1 is shuttle-shaped as a whole, with an octagon in the middle and quadrilaterals at both ends, and the upper mouth of the harp is staggered and connected to the roof, arranged at a certain angle. The length of the harp hangers 1 of the entire venue gradually decreases from the middle to the two ends, so they are arranged in a certain arc on the facade. Due to the many angles, types and quantities, the construction is difficult.

[0030] Figure 4 The installation structure of the steel structure installation system in the embodiment of the present invention is schematically shown in FIG. Figure 2 .

[0031] like Figure 4 As shown, in the present invention, the circular tube 5 is fixed below the steel structure grid 6. More specifically, the circular tube 5 can be fixed below the steel structure grid 6 through a steel structure support 7.

[0032] In the present invention, the circular tube 5 is fixed below the steel structure grid 6. More specifically, the circular tube 5 can be fixed below the steel structure grid 6 via a steel structure support 7.

[0033] In addition, in the steel structure installation system proposed in the present invention, the circular tube 5 has a hanging point corresponding to each of the harp hangers 1, and the preset position is the position of each corresponding hanging point. Since the spacing between the fixing members 4 is consistent with the preset grid of the harp hanger 1, it can be ensured that the harp hanger 1 has a uniform and horizontal hanging point. A plurality of the fixing members 4 can be installed on the circular tube 5 in sequence according to the positions of the hanging points. Specifically, the fixing member 4 can be a sleeve 4 sleeved on the circular tube 5. The sleeve 4 can be a self-contained sleeve, which is inserted from one end of the circular tube 5, or it can be a movable and openable sleeve 4 with a two-piece structure, which is fixed to the circular tube 5 by welding or threading during the sleeve process. In some embodiments, the sleeves 4 are sleeved on the circular tube one by one according to the preset positions of each hanging point, and are further fixed to the bottom of the steel structure grid 6 through a steel structure support 7.

[0034] In addition, in the steel structure installation system proposed by the present invention, each of the first connecting members 2 is fixed to the corresponding fixing member 4, each of the second connecting members 3 is fixed to the top of the corresponding harp hanger 1, and each of the first connecting members 2 is fixed to the corresponding second connecting member 3, forming the steel structure installation system. More specifically, the second connecting member 3 can be a first ear plate 3 fixed to the top of the harp hanger 1, and the first connecting member 2 can be an upper ear plate 2 fixed just below the sleeve 4, and the upper ear plate 2 and the first ear plate 3 can be fixed by bolts, so as to fix the upper end of the harp hanger 1 to the round tube. In some embodiments, each of the first ear plates 3 is fully welded to the top of the harp hanger 1. Each of the upper ear plates 2 is welded just below the sleeve 4. The upper ear plate 2 and the first ear plate 3 are fixed by bolts. The bottom end of the harp hanger 1 passes through the glass curtain wall and is fixed to the main structural column.

[0035] In addition, the present invention also provides a steel structure installation system installation method for installing the above-mentioned steel structure installation system, the method comprising the following steps:

[0036] Installation of round tube: Each of the fixing members 4 to which the upper ear plate 2 is fixed is installed on the preset hanging point of the round tube, and the round tube 5 is fixed below the steel structure grid 6. The fixing member 4 can be a sleeve 4 sleeved on the round tube. At this time, the sleeve 4 may not be fixed to the round tube 5, and the angle and position of the upper ear plate 2 can be adjusted by rotation.

[0037] Installation of connecting components: Each of the first hanging ear plate 3 and the second hanging ear plate is respectively fixed to the top and bottom ends of the corresponding harp hanging component 1. In this step, the harp hanging component 1 can be processed in advance in a processing plant, and the first hanging ear plate 3 and the second hanging ear plate at both ends of the harp hanging component 1 are fully welded and transported to the construction site for hoisting.

[0038] Installation of the hanger: fix each of the second ear plates on the main structural column in turn, and fix the first ear plate 3 on the upper ear plate 2. More specifically, the main structural column may have a fixing structure for fixing the second ear plate, such as an ear plate. Each of the second ear plates may be fixed on the ear plate of the main structural column. During the installation of the hanger, an electric hoist may be used for hoisting. Specifically, the electric hoist may be fixed to a reliable structure, and the harp hanger 1 may be pulled straight to the installation point using a bandage. Then align the lower mouth of the harp hanger 1 with the ear plate at the connection point inside the curtain wall and fix it with high-strength screws, and then fix the connection point at the top of the harp hanger 1. If there is a deviation in the fixation, it can be adjusted by rotating the sleeve.

[0039] Fixing of the fixing components: Each of the fixing components is fixed to the round tube 5 to form the steel structure installation system. After the installation positions of the harp hangers 1 are adjusted and fixed, the sleeve 4 is fully welded to the round tube 5 to fix them.

[0040] Furthermore, in a steel structure installation system installation method proposed by the present invention, before the fixing component installation step, the following steps are also included:

[0041] Model adjustment: Scan the on-site dimensions to establish a BIM model, compare it with the design model of the steel structure installation structure, and adjust it to obtain the construction model.

[0042] In the above-mentioned model adjustment step, specifically, since each construction department of the main building is usually only responsible for the design and construction of its own department, it is difficult to fully consider other installation structures of the main building during the premise design, and the steel structure installation system in the present invention is complex in shape and difficult to install. Therefore, in order to prevent conflicts and installation errors in the structural installation of various parts of the main building during the construction process, it is necessary to draw the actual structural model on site before the specific construction. In the present invention, the three-dimensional spatial coordinates of the installation site structure are accurately measured and scanned by precision measuring instruments. According to the scanning results, the BIM software platform is used to draw the on-site measured 3D structural model (i.e., BIM model), and the design model of the steel structure installation system is imported for comparative analysis. The structural errors that may be generated between the design model of the steel structure installation system and other installation structures of the building in the measured installation structure model are eliminated through model integration, and the final decoration construction model is formed after reconstruction and adjustment. The construction model obtained at this time can meet the installation requirements of the steel structure installation system in the present invention.

[0043] In some embodiments, the BIM software platform used is Revit.

[0044] According to the steel structure installation system and installation method involved in this embodiment, it is mainly suitable for installing a hanging structure with a variety of rod specifications and irregular angles under the roof steel structure. Before installation, the sleeve and ear plate suitable for fixing under the steel structure grid are selected and customized according to the layout size to ensure that the deviations in the later construction are within the range that can be eliminated. In the early stage of installation, the model software is used to build the model, and the installation and fixing work of the connecting structure at both ends of the hanging parts is completed before the hanging parts leave the factory, and they are uniformly transported to the site for direct lifting. The steel structure installation system involved in this embodiment can be customized once and processed in batches, which is not only low-cost, but also can effectively avoid a large number of measurements and layouts in the traditional installation method and the error rate in the measurement process, greatly shortening the construction period. Since the steel structure installation system is easy to adjust in time according to the actual installation situation during the installation process, the construction can be completed at one time after the adjustment is completed during the lifting process, which can effectively avoid rework caused by component processing errors.
