Technical Field

[0001] The invention relates to the technical field of steel frame structures, in particular to a prefabricated assembled steel bracket template and a construction process thereof. Background Art

[0002] At present, the development of prefabricated buildings is being vigorously promoted at home and abroad. The characteristics of steel structure "lightweight and high strength" are perfectly in line with the development concept of prefabricated buildings. Prefabricated buildings transfer most of the work to the factory, and the structural components are produced in the factory. At the same time, mechanized lifting and splicing are carried out on site, which improves the construction environment, reduces construction errors, and improves installation and construction efficiency. Prefabricated steel frame structures overcome the influence of welds. The parts connected by beam-column nodes are mass-produced in the factory and assembled directly on the construction site; However, most prefabricated steel support formworks are assembled and fixed with bolts and nuts, which causes the workers to install too slowly, resulting in poor assembly efficiency, and the process of dismantling the formwork is also more cumbersome. After the formwork is installed, concrete needs to be poured inside. If the formwork cannot be well fixed during pouring, it will easily cause the formwork to deviate, affecting the final concrete molding effect.

[0003] Therefore, a prefabricated assembled steel bracket formwork and its construction process are proposed. Summary of the invention

The front and rear ends of the connecting plate are both provided with slots for matching blocks, and the front and rear ends of the inner web are provided with spring grooves for matching blocks.

[0007] As an optimal technical solution, the spring is arranged inside the spring groove, one end of the spring is fixedly connected to the inner wall of the spring groove, and the other end of the spring is fixedly connected to one side of the block, and the block is slidably connected to the inner web through the spring groove.

The hydraulic cylinder can be effectively fixed through the fixing seat. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0018] The following describes an embodiment of the present invention based on its overall structure.

[0019] A prefabricated assembled steel support template, such as Figures 1 to 5As shown, it includes an integral component 100, which includes a bottom plate 110, an inner web 120 is welded to the top of the bottom plate 110, and a stabilizing component 300 is installed on both sides of the top of the bottom plate 110, and a mounting component 200 is slidably connected to both sides of the inner web 120; The mounting assembly 200 includes a block 210, one end of which is fixedly connected to a connecting rod 220, a spring 230 is sleeved on the surface of the connecting rod 220, and an end of the connecting rod 220 away from the block 210 is fixedly connected to a connecting block 240, and a stabilizing assembly 300 includes a first hydraulic cylinder 310, a ball shaft 320 is slidably connected to the top of the first hydraulic cylinder 310, a support plate 330 is fixedly connected to the top of the ball shaft 320, a first connecting pipe 340 is connected to the front surface of the first hydraulic cylinder 310, and the first connecting pipe 340 is away from the first hydraulic cylinder 310. A first telescopic tube 350 is provided at one end of the cylinder 310, and a fixed block 360 is fixedly connected to one end of the first telescopic tube 350 away from the first connecting tube 340. A second connecting tube 370 is connected to one side of the surface of the first hydraulic cylinder 310, and a second hydraulic cylinder 380 is installed at one end of the second connecting tube 370 away from the first hydraulic cylinder 310. A second telescopic tube 390 is connected to one side of the surface of the second hydraulic cylinder 380 away from the second connecting tube 370, and an inclined block 3910 is fixedly connected to one end of the second telescopic tube 390 away from the second hydraulic cylinder 380.

[0020] By fixing the inner web 120 to the top of the bottom plate 110, the connecting plate 140 on the steel frame 130 is inserted into the fixing groove 122 by hoisting, and then the connecting blocks 240 on both sides are pulled to move the clamping block 210 inward to squeeze the spring 230. When the connecting plate 140 is completely inserted into the fixing groove 122, the connecting block is released, so that the clamping block 210 is embedded in the clamping groove 141 under the reaction of the spring 230, and the steel frame 130 and the inner web 120 are fixed. The I-beam 150 is fixed to the top of the steel frame 130, and then the inner mold 160 is placed between the I-beams 150 by hoisting. Finally, the template is poured with concrete. When pouring concrete, since the steel frame 130 has a certain slope, it is prevented that the steel frame 130 is misplaced due to the weight of the concrete during pouring. During pouring, the first hydraulic cylinder 3 below the steel frame 130 is used. 10 and the second hydraulic cylinder 380 stabilize it. Through the cooperation between the ball shaft 320 and the support plate 330, it can be effectively adjusted according to the inclination of the steel frame 130 and closely fit the surface of the steel frame 130.

The connecting plate 140 is arranged in the fixed groove 122 and is slidably connected to the inner web 120.

[0022] By inserting the steel bar skeleton 130 and the inner web 120 into the fixing groove 122 through the connecting plate 140, the fixing effect is effectively enhanced.

[0023] Please refer to Figure 3, slots 141 that fit the clamping blocks 210 are provided at both the front and rear ends of the connecting plate 140. Spring grooves 121 that fit the clamping blocks 210 are provided at both the front and rear ends of the inner web 120. The spring 230 is arranged inside the spring groove 121.

The inclined block 3910 fits against the bottom surface of the steel bar framework 130. The end of the fixing block 360 away from the first telescopic tube 350 fits against the connecting block 240.

[0026] Through the action of the first hydraulic cylinder 310 and the second hydraulic cylinder 380, the stability effect is enhanced during concrete pouring.

[0027] When in use, the inner web 120 is fixed to the top of the bottom plate 110, and the connecting plate 140 on the steel frame 130 is inserted into the fixing groove 122 by hoisting, and then the connecting blocks 240 on both sides are pulled to move the clamping block 210 inward to squeeze the spring 230.

During pouring, the first hydraulic The cylinder 310 and the second hydraulic cylinder 380 stabilize it. Through the cooperation between the ball shaft 320 and the support plate 330, it can be effectively adjusted according to the inclination of the steel frame 130 and closely fit the surface of the steel frame 130. When pouring concrete, under the action of gravity, the oil inside the first hydraulic cylinder 310 and the second hydraulic cylinder 380 squeezes the inclined block 3910 through the second telescopic tube 390, so that the inclined block 3910 precisely fits the steel frame 130, further strengthening the fixing effect of the steel frame 130. At the same time, under the action of pressure, the oil in the first hydraulic cylinder 310 enters the first connecting pipe 340, and then drives the fixing block 360 to extend through the first telescopic tube 350, so that the fixing block 360 fits one end of the connecting block 240, and performs a certain fixing effect on the installation component 200 to prevent loosening during pouring.
