Construction method of dense rib floor system with die box capable of being repeatedly utilized

Abstract

The invention discloses a construction method of a dense rib floor system with a die box capable of being repeatedly utilized. The construction method comprises the following steps of prefabricating ahollow die box according to the requirements of a construction process, wherein the hollow die box is composed of a top face and a lower frame which is fixed to the outer edge of the top face, extends downwards in the slant direction and is integrally formed with the top face, the lower end of the lower frame is bent outwards to form a turning edge which is 6-10 mm thick, and a plurality of vertical positioning holes are formed in the turning edge in the circumferential direction at intervals; after a die box layout chart is drawn, conducting paying-off on a wood formwork of a civil structure; placing and fixing the hollow die box; binding ribbed beam rebars; pouring concrete; and dismantling the hollow die box. According to the construction method of the dense rib floor system with the die box capable of being repeatedly utilized, there is no need to use bamboo plywood, wooden strips or extrusion molding strips to seal or fill the outer edge of the die box, the construction procedureis simple, and form removal is convenient.

Description

technical field [0001] The invention designs a densely ribbed beam, and in particular relates to a construction method for a densely ribbed floor with reusable mold boxes. Background technique [0002] The ribbed floor is widely used in cast-in-place reinforced concrete or prestressed steel bars due to its saving of building materials, lightening of the floor's own weight, convenient construction, and the use of specific structural forms to obtain excellent performances such as heat preservation, heat insulation, sound insulation, energy saving, and earthquake resistance. In the floors, roofs and bridges of concrete structures, the cavity formwork is more and more widely used in floor pouring. At present, the development of the mold box has mainly gone through two generations. The first-generation mold box uses a disposable formwork shell, which is easy to fall off, return to alkali, break, have non-standard wall thickness, and is easy to leak during construction; the second...

Problems solved by technology

This method uses connecting holes and connecting beams instead of traditional bamboo plywood, wooden strips or extruded strips, which is more convenient to install than the traditional method, but the structure of the above-mentioned mold box components is more complicated, which increases the cost
