Description

Technical Field

[0001] The utility model relates to the technical field of steel structure buildings, in particular to a building steel structure that is convenient for high-altitude installation. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets.

[0003] Existing building steel structures that are easy to install at high altitudes need to be hoisted during the installation process. However, during the hoisting process, when the steel structure pillars move to the installation position, due to their own heavy weight, it is still difficult to control them to align with the designated bolt holes at the installation position. At this time, construction workers generally wait until the shaking stabilizes and then use bolts to insert into one or two bolt holes for guidance. However, due to the lack of limit stops in this guidance, the bolts may slip out of the bolt holes during the shaking of the pillars, reducing the installation efficiency. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a building steel structure that is easy to install at high altitude, so as to solve the technical problem that the guide bolts may slip out of the bolt holes when the columns shake.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a building steel structure that is easy to install at high altitude, including a column, the bottom end of the column is fixedly connected to a base plate, the base plate is provided with bolt holes, and a plurality of bolt holes are provided, wherein a pulling mechanism is fixedly connected to the bolt holes at the corners, and the pulling mechanism includes a bracket, a ball ring is fixedly connected to the bracket, a rotating ball is engaged inside the ball ring, the internal thread of the rotating ball is connected to a pull rod, and the bottom end of the pull rod is rotatably connected to a limiting rod.

[0006] By adopting the above technical solution, the design of the bracket, ball ring, rotating ball and pull rod in the pulling mechanism allows the angle to be adjusted in multiple directions, so that the pull rod can be more easily inserted into the bolt hole at the top of the installed column, further improving the accuracy and efficiency of the installation.

[0007] Furthermore, the bottom end of the pull rod is rotatably connected to a limiting plate, and a clearance groove is provided on the limiting plate.

[0008] By adopting the above technical solution, the limit plate rotatably connected to the bottom end of the pull rod provides additional stability and safety for the equipment, ensuring that the pull rod can be firmly stuck in the bolt hole during the lifting process and is not easy to slip out.

[0009] Furthermore, four limit rods are provided, and the four limit rods are evenly arranged in a ring shape along the central axis of the pull rod.

[0010] By adopting the above technical solution, the number of the limiting rods is set to four, and they are evenly arranged in a ring shape along the central axis of the pull rod, so that the pull rod can be more stable after being inserted into the bolt hole.

[0011] Furthermore, four of the clearance grooves are provided, and the four clearance grooves are evenly arranged in a ring shape along the central axis of the limiting plate.

[0012] By adopting the above technical solution, the number of the clearance grooves is set to four, and they are evenly arranged in a ring shape along the central axis of the limiting plate, so that the four limiting rods can be rotated downward to a vertical state at the same time, and the smoothness and consistency of the rotation are guaranteed.

[0013] Furthermore, the bracket and the base plate are fixedly connected, and the rotating ball is made of metal.

[0014] By adopting the above technical solution, the fixed connection between the bracket and the base plate enhances the overall stability of the pulling mechanism, so that during the lifting process, the pulling mechanism can withstand greater tension and pressure and is not easily deformed or damaged.

[0015] Furthermore, four pulling and connecting mechanisms are provided, and the four pulling and connecting mechanisms are evenly arranged in a ring shape.

[0016] By adopting the above technical solution, the number of pulling mechanisms is set to four, and they are evenly arranged in a ring shape at the bottom end of the column, so that during the installation process, the column can be subjected to uniform pulling force from four directions, effectively preventing the column from tilting or shifting, and improving the accuracy of installation.

[0017] Furthermore, the bracket and the base plate are rotatably connected via a rotating shaft.

[0018] By adopting the above technical solution, the bracket and the base plate are rotatably connected through the rotating shaft, so that the pulling mechanism can be rotated to one side when not in use, freeing up the space above the bolt hole to facilitate subsequent bolt installation operations, thereby improving the flexibility and efficiency of construction.

[0019] In summary, the utility model mainly has the following beneficial effects:

[0020] 1. The utility model realizes stable support and precise positioning of the column during high-altitude installation by setting the column, the bottom plate and the pulling mechanism, and improves the accuracy and efficiency of the installation. The pull rod, the limit rod and the limit plate in the pulling mechanism enable the column to be installed quickly during the hoisting process, and can be easily disassembled after the installation is completed, without causing interference to the subsequent bolt installation operation, so that the column can be reliably guided for installation, and the technical problem that the bolt may slip out of the bolt hole when the column shakes is solved;

[0021] 2. The utility model realizes a rotational connection between the bracket and the base plate by setting a rotating shaft, so that after the pull rod is raised, the bracket can be flexibly rotated to one side, freeing up the space above the bolt hole, facilitating subsequent bolt installation operations, and improving the convenience and efficiency of construction.

[0030] The following describes an embodiment of the utility model based on its overall structure.

[0031] Embodiment 1:

[0032] A building steel structure that is easy to install at high altitude, such as Figure 1-Figure 4 As shown, it includes a column 1, the bottom end of the column 1 is fixedly connected to a base plate 2, the base plate 2 is provided with bolt holes 3, and a plurality of bolt holes 3 are provided, wherein the bolt holes 3 at the corners are fixedly connected to a pulling mechanism 4, the pulling mechanism 4 includes a bracket 401, the bracket 401 is fixedly connected to a ball ring 402, the inside of the ball ring 402 is engaged with a rotating ball 403, the internal thread of the rotating ball 403 is connected to a pull rod 404, the bottom end of the pull rod 404 is rotatably connected to a limiting rod 405, the bracket 401, the ball ring 402, the rotating ball 403 and the pull rod 404 in the pulling mechanism 4 are arranged The design allows the angle to be adjusted in multiple directions, so that the pull rod 404 can be more easily inserted into the bolt hole 3 on the top of the installed column 1, further improving the accuracy and efficiency of the installation. At the same time, the multiple bolt holes 3 opened on the base plate 2 at the bottom end of the column 1 and the pulling mechanism 4 fixed at the corners provide convenience for high-altitude installation, so that the column 1 can be more accurately connected to the designated installation position. The limit rod 405 at the bottom end of the pull rod 404 can form a limit after being inserted into the bolt hole 3, effectively reducing the shaking amplitude of the column 1 and providing stable conditions for subsequent bolt installation.

[0033] See also Figure 3The bottom end of the pull rod 404 is rotatably connected to a limit plate 406, and a clearance groove 407 is provided on the limit plate 406. The limit plate 406 rotatably connected to the bottom end of the pull rod 404 provides additional stability and safety for the equipment, ensuring that the pull rod 404 can be firmly stuck in the bolt hole 3 during the lifting process and is not easy to slide out. At the same time, the clearance groove 407 provided on the limit plate 406 enables the limit rod 405 to be rotated downward to a vertical state when necessary, which is convenient for subsequent removal from the bolt hole 3, thereby ensuring the stability of the installation and improving the convenience of construction.

[0034] See also Figure 2 and Figure 3 There are four limit rods 405, and the four limit rods 405 are evenly arranged in a ring shape along the central axis of the pull rod 404. The number of the limit rods 405 is set to four, and they are evenly arranged in a ring shape along the central axis of the pull rod 404, so that the pull rod 404 can be more stable after being inserted into the bolt hole 3. At the same time, the uniform arrangement in the ring also makes it possible to maintain a stable force distribution when it is necessary to rotate the pull rod 404 to drive the column 1 to descend, thereby improving the accuracy and stability of the installation.

[0035] See also Figure 3 There are four give-way grooves 407, which are evenly arranged in a ring shape along the central axis of the limiting plate 406. The number of the give-way grooves 407 is set to four, and they are evenly arranged in a ring shape along the central axis of the limiting plate 406, so that the four limiting rods 405 can be rotated downward to a vertical state at the same time, and the smoothness and consistency of the rotation are guaranteed. At the same time, the uniform arrangement in the ring also makes it possible for each limiting rod 405 to correspond to a give-way groove 407 after the limiting rod 405 rotates, and there will be no interference or offset between them.

[0036] See also Figure 1 The bracket 401 and the base plate 2 are fixedly connected, and the rotating ball 403 is made of metal. The fixed connection between the bracket 401 and the base plate 2 enhances the overall stability of the pulling mechanism 4, so that during the lifting process, the pulling mechanism 4 can withstand greater tension and pressure and is not easily deformed or damaged. At the same time, the rotating ball 403 is made of metal, which not only improves its strength and wear resistance, so that it can withstand repeated rotation and friction for a long time without being easily damaged, but also facilitates threaded connection with the pull rod 404, thereby improving the firmness and stability of the connection.

[0037] See also Figure 1There are four pulling mechanisms 4, which are evenly arranged in a ring shape. The number of the pulling mechanisms 4 is set to four, and they are evenly arranged in a ring shape at the bottom end of the column 1, so that during the installation process, the column 1 can be subjected to uniform pulling force from four directions, which effectively prevents the column 1 from tilting or shifting, and improves the accuracy of installation. At the same time, the evenly arranged ring shape of the four pulling mechanisms 4 also makes it more flexible to operate when the position of the column 1 needs to be adjusted, because no matter which direction the pulling force needs to be adjusted, it can be achieved through the corresponding pulling mechanism 4, which improves the convenience and efficiency of construction.

[0038] The implementation principle of the utility model is as follows: first, after the column 1 is transported to the designated position, a pull rod 404 is held and the angle is adjusted so that it can be inserted into the bolt hole 3 at the top of the installed column 1. At this time, the limit rods 405 around the bottom of the pull rod 404 and the bolt hole 3 form a limit, tightening the column 1 to reduce its shaking amplitude, and then hold the pull rods 404 at other positions, adjust the angle and insert them into the corresponding bolt holes 3;

[0039] When the four columns 1 are inserted, hold the rotating ball 403 and rotate the pull rod 404, so that the columns 1 can be driven down to achieve the effect of the columns 1 being closely connected;

[0040] When the bolts at other positions are installed, the limiting plate 406 is rotated. At this time, the clearance groove 407 on the limiting plate 406 is opposite to the limiting rod 405, so that the limiting rod 405 can be rotated downward to form a vertical state, which is convenient for subsequent removal from the bolt hole 3;

[0041] Finally, hold the rotating ball 403 and rotate the pull rod 404, so that the pull rod 404 rises and comes out of the bolt hole 3, and then install the last four bolts to complete the connection.

[0042] Embodiment 2:

[0043] See also Figure 4 The bracket 401 and the base plate 2 are rotatably connected via the rotating shaft 5, so that the pulling mechanism 4 can be rotated to one side when not in use, leaving space above the bolt hole 3 to facilitate subsequent bolt installation operations, thereby improving the flexibility and efficiency of construction. At the same time, the rotating connection method also enables the pulling mechanism 4 to remain stable when subjected to tension, thereby enhancing the overall stability and safety of the equipment.

[0044] The implementation principle of the utility model is as follows: first, when the pull rod 404 is raised, the bracket 401 is rotated so that the bracket 401 can be rotated to one side to make room above the bolt hole 3 for bolting.
