Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a slurry leakage prevention device for sealing a rubber plate at the bottom of an aluminum mold. Background Art

[0002] The aluminum formwork for wall columns is composed of a fixed wall panel formwork (60mm×40mm angle aluminum is set at the bottom of the inner wall formwork and the inner formwork of the outer wall, and a K plate is set at the top of the outer wall outer formwork), back ribs, tension screws and diagonal braces. In order to ensure smooth installation and convenient elevation adjustment, a 10mm gap needs to be reserved between the lower end of the angle aluminum and the concrete floor slab. In order to avoid leakage here when pouring concrete, the construction unit needs to fill and seal it by itself. Generally, traditional processes use cement mortar to fill and seal. It was found through on-site construction that there is only a 50mm distance from the upper end of the aluminum formwork angle aluminum to the surface of the concrete floor slab. When workers use traditional cement mortar to seal, it is difficult to observe, and the sealing is prone to omissions and loose sealing. In addition, a large amount of cement mortar is required, which leads to low construction efficiency and difficulty for management personnel to check. After pouring concrete, the cement mortar needs to be chiseled, which increases the task of cleaning and transporting floor garbage, and is easy to cause dust on site, which is not conducive to maintaining civilized construction on site.

[0020] An aluminum formwork wall panel 2 is installed on one side of the concrete wall 1 to be cast, the aluminum formwork wall panel 2 is placed on the top of the aluminum formwork angle aluminum 4, and a first hole 201 is reserved at the bottom of the aluminum formwork wall panel 2; and the first hole 201 and the second hole 401 are aligned.

[0021] The short square wood 6 is arranged inside the aluminum formwork wallboard 2, and the steel bar ends of the L-shaped bolt reinforcement member 5 are inserted into the aligned first hole 201 and the second hole 401.

[0022] The L-shaped bolt reinforcement member 5 is externally sleeved with a mountain-shaped clamp 8 and a locking nut 9, the inner bottom end of the mountain-shaped clamp 8 is clamped on the rubber sheet 3, the inner top end of the mountain-shaped clamp 8 is clamped on the short square wood 6, and the mountain-shaped clamp 8 is locked by the locking nut 9, so as to indirectly reinforce the rubber sheet 3;

[0023] The L-shaped bolt reinforcement member 5 includes a threaded screw 501 and a steel bar 502. The threaded screw 501 is a screw with a length of 150 mm and a diameter of 12 mm. The steel bar 502 is a steel bar with a length of 30 mm and a diameter of 12 mm. The top end of the steel bar 502 is welded to the outer end of the threaded screw 501, and the threaded screw 501 and the steel bar 502 form an L shape as a whole.

[0024] The sealing method of the rubber plate at the bottom of the aluminum mold to seal the anti-leakage slurry device:

[0025] Step (1), clean the bottom of the aluminum template angle aluminum 4, insert a rubber sheet 3 with a cross-section of 30mm×60mm, and make the side of the rubber sheet 3 fit tightly against the lower side of the aluminum template angle aluminum.

[0026] Step (2) uses a 150 mm long, 12 mm diameter through-thread screw and welds a 30 mm diameter 12 mm steel bar to one end of the screw to form an L-shaped bolt reinforcement component.

[0027] Step (3), arrange short square wood with a cross-section of 40mm×60mm inside the aluminum formwork wall panel 2 and basically perpendicular to the rubber sheet 3 in the same plane, so as to increase the stability of the mountain-shaped card 8 reinforcement.
