Description

Inorganic glass fiber reinforced plastic dismounting-free disposable building internal mold

Technical Field

The utility model relates to a mould shell for making wall, floor, ceiling or roof, in particular to an inorganic glass fiber reinforced plastic non-dismantling disposable building inner mould.

Background

The building shuttering is widely used for multi-storey and high-rise buildings with large span, large load and large space due to its superior cost performance, the construction of the building shuttering is rapid, and after the concrete is poured and formed, the construction time is greatly shortened without detaching the film. The part of the glass fiber magnesite building formwork, which is not contacted with cast-in-place concrete, needs to have smooth and clean surface and neat and complete corners.

Chinese patent CN 201891202U discloses a BRT anti-drop type light weight high strength building formwork, which comprises a top plate (1), a reinforcing material (2), a side plate (3), a bottom plate frame (4) and a steel bar (5), wherein the reinforcing material (2) is arranged in the formwork shell, the side plate (3) is arranged around the lower end of the top plate (1), an angle alpha with the top plate (1) is 95-110 °, the bottom frame (4) is arranged at the bottom of the side plate (3), and the steel bar or steel wire mesh (5) is uniformly inserted into the bottom frame (4) and extends out. The utility model discloses bear the weight of dynamic height, light in weight, waterproof, fire behavior is good, and it is firm to combine with the post-cast concrete, is difficult for droing.

Chinese patent CN 204983350U discloses an environmental protection composite building formwork, which is a square groove shaped shell composed of a top plate (1), side plates (2) and a bottom frame (3), the outer side of each side plate (2) is provided with a plurality of column-shaped protruding points (4) or column-shaped recessed points (5), and the side plate (2) is provided with an included angle α of 0-20 degrees relative to the vertical direction of the side plate (2). The thickness of the square groove-shaped shell is 20-60 cm, the length of the bottom frame (3) is 80-130 cm, and the width of the bottom frame (3) is 3-8 cm. The number of the columnar protruding points (4) or the columnar recessed points (5) is 4-6. The utility model discloses fundamentally has prevented droing of building mould shell, and waterproof fire resistance is high.

Widely used building formworks generally include iron formworks, wooden formworks, organic material formworks, gypsum formworks, GRC sulphoaluminate cement formworks and formworks made of magnesite materials.

The disposable glass fiber reinforced plastic building formwork has excellent heat insulating and sound isolating effect and high fireproof performance. And the formwork construction process is simple, after the floor bottom die is paved, the formwork is directly placed, the formwork is adjusted and fixed, and finally the small rib beam is bound. After the concrete is poured, the formwork and the concrete are combined together without detaching the formwork, so that the construction period is shortened, and the material and labor cost are saved.

However, in the prior art, even if the weight and the strength of the formwork are satisfactory, the formwork falls off due to the design defects of the formwork, particularly the insecure connection between the formwork and the cast-in-place concrete. At present, the outer peripheral edge of a bottom frame plate of an everted building formwork is generally of a right-angle structure, the material properties of the formwork and solidified concrete slurry are different, the formwork and the solidified concrete slurry are not firmly bonded, hidden dangers are left for the infirm combination of the formwork and cast-in-place concrete, and particularly, the phenomenon that the formwork falls off after construction occurs.

SUMMERY OF THE UTILITY MODEL

The utility model provides an inorganic glass fiber reinforced plastic non-dismantling disposable building inner mold, aiming at solving the problems that the mold shell is not firmly combined with cast-in-place concrete to cause the mold shell to fall off due to the design defects of the mold shell in the prior art.

The utility model discloses a realize according to following technical scheme.

The inorganic glass fiber reinforced plastic non-dismantling disposable building inner mold comprises a square groove shaped inner mold with four corners formed by a top plate, peripheral side plates and peripheral bottom frames, and is an isosceles trapezoid with the bottom frames outwards turned in side view, inclined planes downwards are formed on the free edges and the outer side angles of the bottom frames, or the free edges and the outer side angles outwards extend to form inclined planes, and an included angle alpha formed between each inclined plane and the bottom plane of each bottom frame is 0-90 degrees.

The utility model discloses design like this, keep somewhere need not to demolish on the building in the work progress to form an organic whole with the building. The free edge of the bottom frame which is turned outwards is provided with an acute angle formed by a bevel face which is downward, so that the free edge of the bottom frame is more closely combined with the cast-in-place concrete in a filling way, a more stable effect is achieved after the building formwork is loaded, the hidden danger caused by the weak combination of the building formwork shell and the cast-in-place concrete is solved, and the falling of the formwork is avoided.
