Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a multifunctional steel grid construction device and a construction method thereof. Background Art

[0002] With the vigorous development of the construction industry, more and more large-scale factory buildings use steel grid structures for support. It is difficult to ensure the installation quality of the steel grid when it is assembled on site, especially the positioning and installation of the ball joint on the steel grid. Since the steel grid is installed on the masonry structure, when the installation elevation of the ball joint needs to be adjusted, the traditional construction method is to support multiple jacks between the steel grid and the masonry structure. However, due to the narrow space between the steel grid and the masonry structure, the installation of the jack is very difficult, and even large hoists are needed to lift the steel grid, resulting in low construction efficiency. In addition, due to the high installation height of the ball joint, the installation of the ball joint mostly adopts the overhead welding construction method, and overhead welding is the most difficult to ensure installation quality. Summary of the invention

[0003] The purpose of the present invention is to overcome the defects of the prior art and provide a multifunctional steel grid construction device and a construction method thereof, which is convenient for adjusting the installation height of the steel grid and also allows construction personnel to use flat welding when installing ball joints, thereby improving the construction quality.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is a multifunctional steel grid construction device, including a base plate, a support tube, a lifting device and an overhead platform, wherein: the lifting device is detachably connected to the base plate and is used to adjust the installation height of the steel grid; the support tube is height-adjustably fixed to the base plate, and is used to support the steel grid after the steel grid is lifted into place, and an installation space for accommodating the lifting device is formed inside the support tube, and an extension port for extending the lifting device is provided at the top of the support tube, and a receiving and placing port for placing and removing the lifting device is provided on one side of the support tube, and at least one connecting ear is connected to the top of the support tube at intervals; the overhead platform is used for personnel to install the ball joint on the steel grid, and one side of the overhead platform is selectively detachable and connected to multiple connecting ears.

[0005] A further improvement of the multifunctional steel truss construction device of the present invention is that the support cylinder includes a fixed cylinder and a plurality of movable cylinders stacked on the top of the fixed cylinder to adjust the overall height of the support cylinder, the cross-sections of the fixed cylinder and the movable cylinder are both U-shaped, the U-shaped opening of the fixed cylinder is formed as the taking and releasing port, the outer periphery of each of the movable cylinders is connected to at least one of the connecting ears, and the stacking direction of the movable cylinders on the fixed cylinder is adjustable.

[0006] A further improvement of the multifunctional steel grid construction device of the present invention is that a support rod for supporting the ground is connected to the bottom of the overhead platform, and a connecting rod is connected to one side of the overhead platform, and the connecting rod is detachably connected to the connecting ear.

[0007] A further improvement of the multifunctional steel grid construction device of the present invention is that an inverted U-shaped clip for snapping into the connecting ear is connected to the bottom of one end of the connecting rod relatively far from the overhead platform.

[0008] A further improvement of the multifunctional steel grid construction device of the present invention is that the support rod is a telescopic rod.

[0009] A construction method of a multifunctional steel grid comprises the following steps:

[0010] Step 1: providing the above-mentioned multifunctional steel grid construction device;

[0011] Step 2: Place the steel grid on top of the support tube;

[0016] Step 7: Provide a ladder, set up the ladder on the overhead platform, and have construction workers enter the overhead platform through the ladder to weld the ball joint.

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] 1. By setting the support tube, the installation and disassembly of the lifting device is facilitated without affecting the jacking of the lifting device.

[0019] 2. By setting up an overhead platform, it is convenient for construction workers to stand on the overhead platform to perform flat welding on the ball joint. BRIEF DESCRIPTION OF THE DRAWINGS
