Description

Technical Field

[0001] The utility model relates to the technical field of composite plate reinforcement construction, in particular to a composite plate and aluminum mold reinforcement system. Background Art

[0002] The composite slab is an integral slab that combines prefabricated assembly and cast-in-place concrete. The lower half of the composite slab is prefabricated, and the upper half is cast-in-place, which are combined into a whole and work together. For projects with standard floors that use an aluminum formwork support system and contain composite slabs, in theory, both the composite slab and the aluminum alloy formwork are flat plate surfaces. However, in actual construction situations, the degree of fit between the composite slab and the aluminum alloy formwork is not ideal, resulting in a large gap between the composite slab and the aluminum alloy formwork.

[0003] Some projects have grooved the aluminum alloy formwork. Before installing the composite board, rubber strips are added to the contact position between the composite board and the aluminum alloy formwork. Some larger gaps cannot be sealed with rubber strips. In addition, since the composite board is not fixed, workers step on the composite board during concrete pouring, which will cause the gap to increase. After the concrete is poured, this position is prone to leakage and roughness, and the appearance of the concrete is poor. Water leakage may occur in some positions. At a later stage, additional manpower is needed to chisel and repair this position, which increases the project cost. Utility Model Content

The aluminum alloy template 2 is arranged below the composite plate 1 and overlaps with the composite plates 1 on both sides. A pressure groove 21 is opened at the overlap position of the aluminum alloy template 2, and a rubber strip is attached to the pressure groove position. Two steel pipes 3 are arranged in parallel below the aluminum alloy template 2. The reinforcement device 4 is a T-shaped structure, and multiple reinforcement devices 4 are arranged at intervals. The upper end of the reinforcement device is located above the composite plate 1 and higher than the plate surface elevation, and the lower end vertically passes through the aluminum alloy template 2 and is fixed to the steel pipe 3.

[0021] The reinforcement device 4 includes an upper steel bar 41, a lower screw rod 42 and a butterfly buckle 43. The upper steel bar 41 is arranged above the composite plate 1 in the horizontal direction. The upper steel bar 41 is perpendicular to the horizontal post-cast plate strip 5. The upper steel bar 41 and the composite plate 1 are provided with a support structure 6. The support structure 6 is a steel bar stool or a prefabricated block. The upper end of the lower screw rod 42 is vertically fixed on the upper steel bar 41, and the lower end of the lower screw rod 42 passes through the hole at the bottom of the aluminum alloy formwork 2 and extends to the bottom of the steel pipe 3. The diameter of the hole shall not be greater than the diameter of the lower screw rod 42 + 4mm. The butterfly buckle 43 is threadedly connected to the lower screw rod 42 and fixed below the steel pipe 3. The steel pipe 3 is arranged in the same direction as the upper steel bar 41, and the length of the steel pipe 3 is not shorter than the length of the upper steel bar 41.

[0022] Furthermore, two adjacent reinforcement devices 4 are evenly arranged at a distance of 600 mm. The diameter of the upper steel bar 41 is not less than 20 mm, and the length of the upper steel bar 41 is at least 200 mm greater than the spacing between the two side laminated plates 1. The diameter of the lower screw rod 42 is not less than 18 mm, and the length of the lower screw rod 42 extending out of the aluminum alloy template 2 is at least 300 mm.

[0023] Furthermore, the groove 21 is U-shaped, with a width of 20 mm and a depth of 2 mm. The position of the groove 21 is 30 mm away from the edge of the aluminum alloy template, and the thickness of the rubber strip is 3 mm greater than the depth of the groove.

[0024] The following is an introduction to the construction process of the composite board and aluminum formwork reinforcement system of the utility model:

[0025] 1) The aluminum alloy template 2 is deepened, the overlap width between the composite plate 1 and the aluminum alloy template 2 is not less than 50mm, and a groove 21 is set at the overlap position between the aluminum alloy template 2 and the composite plate 1. The groove 21 is 20mm wide and 2mm deep, and the position of the groove 21 is 30mm away from the edge of the aluminum mold.

[0026] 2) Paste a rubber strip on the groove position of the aluminum alloy template. The thickness of the rubber strip should be 3mm greater than the groove. Install the aluminum alloy template 2 and level the aluminum film pole 7 and the aluminum alloy keel.

[0027] 3) Install the composite board 1 and correct it to ensure its shelf length, and its allowable deviation is no more than 5 mm. After the installation of the composite board 1 is completed, the steel bars are tied.

[0028] 4) Make a T-shaped reinforcement device 4. The upper steel bar 41 is made of steel waste with a diameter of not less than 20 mm and a length at least 200 mm greater than the spacing between the two side composite plates 1. The lower screw rod 42 has a diameter of not less than 18 mm and a length of at least 300 mm extending from the lower end of the aluminum alloy template 2. The end of the lower screw rod 42 is welded to the middle of the upper steel bar 41 (welding quality must be ensured).

[0029] 5) Install multiple reinforcement devices 4, and the reinforcement devices 4 are evenly arranged with a spacing of 600mm. The upper steel bar 41 is perpendicular to the horizontal post-cast slab strip 5. The upper steel bar 41 needs to be higher than the slab elevation (a steel bar stool or prefabricated block is used between the upper steel bar 41 and the composite slab for support). The placement of the device requires a hole to be opened at the bottom of the aluminum alloy formwork to tighten and fix it. The hole diameter shall not be greater than the diameter of the lower screw 42 + 4mm. The lower screw 42 passes from top to bottom. The lower part of the lower screw 42 uses a butterfly buckle 43 and two steel pipes 3. The length of the steel pipe is not shorter than the upper steel bar 41 and is in the same direction as the upper steel bar 41. The lower screw 42 and the aluminum film vertical pole 7 are staggered.

[0030] 6) After the reinforcement is completed, pour the concrete. After the initial setting of the concrete is completed, rotate and loosen the lower butterfly buckle 43 to take out the reinforcement device for turnover use.
