Description

Technical Field

[0001] The invention relates to a multi-layer space reinforcement grid structure steel bar positioning tool and a use method thereof, which is used for accurate positioning and installation of steel bars in a complex space reinforcement grid structure, and belongs to the technical field of steel bridge manufacturing. Background Art

[0002] Reinforced concrete cable-stayed bridge towers are usually composed of a steel frame that bears the main structural forces and a concrete tower body that improves the structural strength. However, in order to achieve modular and rapid assembly construction requirements and concepts, the current technology tends to realize the component construction of steel frame + steel frame in the factory, and then transport the steel frame + steel frame components to the bridge site for installation and pouring concrete to form the tower column. For the steel + steel component grid segments of complex variable cross-section spatial structures, in factory manufacturing, because the overall structure is a spatial inclined structure, the spatial curved steel bars are densely distributed on the spatial steel frame, the steel bars are difficult to install, the precision is high, and the tower has high requirements for the steel bar protection layer (the steel bar installation positioning deviation is 0, +10mm). There were no related construction examples in my country before, and there was insufficient experience in complete construction. For the production of a generally regular uniform cross-section steel frame + steel bar component-type grid structure, the traditional steel bar positioning tool is relatively simple, that is, horizontal and vertical stiffening ribs are set on the grid structure, circular holes are opened on the stiffening ribs, and the steel bars are inserted from one end of the circular hole into the other end of the circular hole for fixing. For the steel bar installation of the steel frame + steel bar component-type space steel bar grid structure, the traditional steel bar positioning tool is used, and it is impossible to insert the curved steel bars. Summary of the invention

[0003] Design purpose: To avoid the shortcomings of the background technology, by analyzing the steel frame + steel bar type space reinforcement grid structure, a multi-layer space reinforcement grid structure steel bar positioning tooling and its use method are designed and developed with high assembly accuracy, fast speed, reliable and safe installation, and effective control of the "twisted" steel bar spatial positioning.

[0004] Design scheme: In order to achieve the above design objectives. The present invention is designed with steel bar positioning tooling: the steel bar inner horizontal limit slot plate, the steel bar outer horizontal limit slot plate, the outer seal and the support bracket are composed of four parts. By fixing it in advance on the spatial grid structure, the steel bar inner horizontal limit slot plate, the steel bar outer horizontal limit slot plate, the outer baffle and the support bracket are fixed in advance on the spatial grid structure, which can effectively achieve the precise positioning of various complex spatial curved steel bars, effectively solve the problem of spatial precise positioning of "twisted" steel bars, and at the same time greatly improve the construction efficiency. Figure 1 .

[0005] Technical Solution 1: A spatial multi-layer reinforced grid structure steel bar positioning tooling, the inner horizontal limit slot plate of the steel bar and the outer horizontal limit slot plate of the steel bar are supported by multiple supporting brackets, the outer baffles are respectively located on the inner horizontal limit slot plate of the steel bar and the outer horizontal limit slot plate of the steel bar, and the side end surfaces of the inner horizontal limit slot plate of the steel bar and the outer horizontal limit slot plate of the steel bar 1 are provided with grooves for the steel bars to pass through.

[0006] Technical Solution 2: A method for using a steel bar positioning tool for a spatial multi-layer reinforced grid structure. When positioning and installing the steel bars of a spatial multi-layer reinforced grid structure of a steel frame + steel bar type, first install the supporting corbel on the grid structure, and then install the inner horizontal limit slot plate of the steel bar to the grid supporting corbel, focusing on controlling the horizontal and vertical horizontal positions of the limit slot plate to ensure the precise position of the slot; then the first layer of "twisted" steel bars are inserted into the horizontal slot as a whole from one side, with the bottom end on a horizontal platform, to ensure that the top and bottom of the steel bars are respectively on the horizontal plane; then install the outer horizontal limit slot plate 1 of the steel bar in place according to the horizontal and vertical reference lines, and at the same time, the outer horizontal limit slot plate of the steel bar also limits the displacement of the first layer of steel bars; finally, assemble the second layer of steel bars for installation, and after adjusting the positions of all steel bars, immediately install the outer baffle to complete the precise positioning and installation of complex spatial curved steel bars.

[0007] Compared with the background technology, the present invention has the following advantages: first, the steel bar positioning tool can be used for the steel bar installation and construction of spatial reinforced grid structures with any complex shape, multiple layers of steel bars, and any inclination angle, and has a wide range of applications and strong applicability; second, the device has a simple structure, easy installation, precise positioning, and a high steel bar installation rate, which can greatly shorten the overall manufacturing period of the complex reinforced grid structure and improve manufacturing efficiency; third, it solves the problem of assembly and positioning of spatial curved steel bars that cannot be achieved by traditional tooling, and promotes the development of cutting-edge technologies.
