Description

Technical Field

[0001] This invention relates to the field of grid structure technology, specifically a construction method for a spatial grid structure cable-stayed partition transition. Background Technology

[0002] Due to the presence of expansion joints, zoning design is often unavoidable in spatial grid structures. Space frames, as a common type of spatial grid structure, often employ a construction method of first installing initial units, then using these initial units as stable support structures for high-altitude assembly. Since the members in each zone are not connected, each zone of the space frame involves a restart process. Common restart methods include overall hoisting, segmented connection, single-sided cambering, and full-span scaffolding. Over 60% of the risks in space frame installation occur during the restart process, which is also significantly more expensive than the assembly process.

[0003] However, existing spatial grid structures, in order to reduce the risks and costs of the initial construction process, require connecting zones together using a piecemeal transition method. But due to architectural functional requirements, the ball joint positions between two zones are relatively small, and conventional designs cannot meet the connection requirements, leading to collisions between the web members. In practical use, when encountering this situation, it is often necessary to add a layer of spheres on the upper or lower chord, effectively turning the connection section between the two zones into a three-layer space frame. This is relatively complicated to construct, including the dismantling of the three-layer members. Due to the asynchronous deformation of the old and new space frames, the dismantling process is also quite troublesome. Based on this, this invention designs a construction method for cable-stayed zone transitions in spatial grid structures to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a construction method for a spatial grid structure cable-stayed partition transition, so as to solve the aforementioned problems of troublesome installation and disassembly.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a spatial grid structure, comprising a first connecting ball, a first threaded hole on the top of the first connecting ball, a first rotating bolt threadedly connected to the inner cavity of the first threaded hole, a vertical connecting rod fixedly connected to the top of the first rotating bolt, a second rotating bolt fixedly connected to the top of the vertical connecting rod, a second connecting ball on the top of the vertical connecting rod, a second threaded hole on the bottom of the second connecting ball, a second rotating bolt threadedly connected to the inner cavity of the second threaded hole, a first limiting hole on the back of the second connecting ball on the front and the front of the second connecting ball on the back, a first limiting bolt threadedly connected to the inner cavity of the first limiting hole, and the first limiting bolts being fixedly connected by a first transition rod.

[0006] As can be seen from the above technical solution, after the grid structure on the front is installed, a hoist is used to lift the grid structure on the back, so that the two grid structures are at the same height. At this time, a first transition rod is used. The first transition rod is fixedly connected to the front and back with a first limiting bolt. The first limiting bolt can be inserted into the inner cavity of the first limiting hole of the second connecting ball, realizing the connection between the second connecting balls on the front and back.

[0007] Preferably, there are four sets of the first threaded holes and the vertical connecting rods. The first threaded holes are distributed in a matrix array and are located on the top of the first connecting ball. The vertical connecting rods are symmetrical about the first connecting ball in pairs and form a "V" shape structure in pairs.

[0008] As can be seen from the above technical solution, the top of the first connecting ball is provided with a first threaded hole, the inner cavity of the first threaded hole is threaded with a first rotating bolt, and the top of the first rotating bolt is fixedly connected with a vertical connecting rod. The vertical connecting rod and the second connecting ball are fixed to each other through the second threaded hole and the second rotating bolt, thereby realizing the fixation between the first connecting ball and the second connecting ball.

[0009] Preferably, a third threaded hole is provided on the side of the second connecting balls that are close to each other, and a third rotating bolt is threaded into the inner cavity of the third threaded hole, and a transverse connecting rod is fixedly connected between the third rotating bolts.

[0010] As can be seen from the above technical solution, the second connecting ball is fixed to the transverse connecting rod by the third threaded hole and the third rotating bolt, thereby improving the stability and fixation of the second connecting ball.

[0011] Preferably, there are four sets of transverse connecting rods, and each pair of them is perpendicular to the other.

[0012] Preferably, the first connecting ball has a fourth threaded hole on both sides, the inner cavity of the fourth threaded hole is threaded with a fourth rotating bolt, and a support rod is fixedly connected to one side of the fourth rotating bolt.

[0013] As can be seen from the above technical solution, the support rod can connect the structures on both sides to form a grid structure.

[0014] Preferably, a second limiting hole is provided on the back of the first connecting ball located on the front and on the front of the first connecting ball located on the back. A second limiting bolt is threaded into the inner cavity of the second limiting hole, and a second transition rod is fixedly connected between the second limiting bolts.

[0015] As can be seen from the above technical solution, by using the second transition rod and inserting the second limiting bolt of the second transition rod into the second limiting hole of the first connecting ball, the stability and connectivity of the grid structure on the front and back sides can be improved.

[0016] Preferably, the outer ring of the first connecting ball is fitted with a first connecting rope, and the top of the first connecting rope is fixedly connected to a first connecting ring; the outer ring of the second connecting ball is fitted with a second connecting rope, and the bottom of the second connecting rope is fixedly connected to a second connecting ring.

[0017] Preferably, a steel chain is provided between the first connecting ring and the second connecting ring, and a storage structure is provided at the top of the steel chain. A first hook is fixedly connected to the top of the storage structure and is disposed in the inner cavity of the first connecting ring. A second hook is fixedly connected to the bottom of the steel chain and is disposed in the inner cavity of the second connecting ring.

[0018] Preferably, the steel chain and the storage structure are in two sets and form a V-shape. The first connecting ring is fitted onto the outer ring of the first connecting ball located on the front, and the second connecting ring is fitted onto the outer ring of the second connecting ball located on the back.

[0019] As can be seen from the above technical solution, the steel chain and the storage structure constitute a suspension cable structure. The first connecting rope is fitted around the outer ring of the first connecting ball, and the second connecting rope is fitted around the outer ring of the second connecting ball, thereby increasing the connectivity between the first connecting ball and the second connecting ball and satisfying the in-plane stability of the new starting net frame. The steel chain and the storage structure utilize the characteristics of axial force rods, with clear separation of tension and compression and a clear division of labor.

[0020] As a further aspect of the present invention: a construction method for a spatial grid structure cable-stayed partition transition, using the aforementioned spatial grid structure, includes the following steps:

[0021] SS001, Moving the grid: After the grid structure on the front is installed, use a hoist to move the grid structure on the back until all grid structures are at the same height, which facilitates the installation of the transition rods;

[0022] SS002. Install the transition rod. The first limiting hole and the first transition rod cooperate to fix the second connecting balls to each other. The second limiting hole and the second transition rod cooperate to fix the first connecting balls to each other, thereby fixing the back mesh structure. The transition rod is also easier to install and remove.

[0023] SS003. The installation of the slings, steel chains and storage structure constitute the sling structure, which can connect and fix the first connecting ball on the front and the second connecting ball on the back, making full use of the characteristics of the axial force rod, with clear division of tension and compression and clear division of labor.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. In this invention, through the cooperation of the first transition rod and the second transition rod, the front and back sides of the first transition rod are fixedly connected with first limiting bolts. The first limiting bolts can be inserted into the inner cavity of the first limiting hole of the second connecting ball, realizing the connection between the second connecting balls located on the front and back sides. By using the second transition rod and inserting the second limiting bolt of the second transition rod into the second limiting hole of the first connecting ball, the stability and connectivity of the grid structure on the front and back sides can be improved. By setting multiple sets of first and second transition rods, installation and removal are convenient, ensuring the out-of-plane stability of the new starting grid frame, and also solving the problem of web member collision and avoiding the trouble of adding three layers of rods locally.

[0026] 2. In this invention, the steel chain and the storage structure work together to form a suspension cable structure. The first connecting rope is fitted around the outer ring of the first connecting ball, and the second connecting rope is fitted around the outer ring of the second connecting ball, thereby increasing the connectivity between the first connecting ball and the second connecting ball and satisfying the in-plane stability of the new starting frame. The steel chain and the storage structure utilize the characteristics of the axial force rod, with clear tension and compression and a clear division of labor. Attached Figure Description
