Problems solved by technology

Concrete densely ribbed floor structure is an excellent structure with light weight, less material, high bearing capacity, and small space occupation. Especially its dense rib arrangement makes it capable of carrying concentrated loads, so that it has the ability to meet multiple requirements. However, due to the complex requirements for the construction mold of the concrete ribbed floor, the traditional wood mold, bamboo mold, steel mold, and aluminum alloy mold are not only complicated in construction, but also difficult to demould. The traditional technology adopts Although various filling forms simplify the construction, because the filling forms cannot be reused, the amount of them increases tens of times and nearly hundreds of times, and because the filling forms cannot be taken out, the load increases, and the internal space of the structure cannot be used, resulting in an increase in the storey height.
[0004] The concrete ribbed floor structure constructed by using the traditional plastic formwork as the construction mold has a history of decades. The existing defects are: 1) Due to the limitation of the demoulding method, it cannot meet the construction requirements of the ribbed bottom flange. As a result, the bottom of the dense ribs uses a large amount of steel due to the small cross-section of the compression area, and the thickened cross-section of the tension area due to the small cross-section width cannot accommodate steel bars, so that the amount of concrete is increased; 2) Due to the weight of the plastic formwork, it is subject to manual handling and installation Restricted, its scale is limited, so that the rib spacing cannot meet the optimal spacing

Abstract

The invention discloses a detachable and reusable mold for concrete floor system construction. The detachable and reusable mold takes a base mold with a cavity appearance as the core, comprises combined parts such as a top mold, a bottom mold, a side mold, a corner mold and an annular mold, can be used for construction of ordinary beam plate structures and particularly can meet the requirements for construction molds of novel complex structures such as the dense rib structure with flanges designed at the bottoms of dense ribs, secondary ribs and secondary secondary-ribs designed to top platesand stiffening ribs designed to webs, the dense rib structure without webs and the dense rib structure with the punched webs. Compared with a dense rib structure constructed by a traditional plastic mold shell, according to the novel dense rib structure, the concrete use quantity is smaller, the rib distance is more reasonable, and the structure is more economical; and compared with the traditional plastic mold shell, the combined type mold is more convenient to produce, carry, mount and detach.

Description

technical field [0001] The invention relates to a concrete floor, in particular to a detachable and reusable construction mold for concrete floor construction and a construction method thereof, belonging to the technical field of building materials. Background technique [0002] The most commonly used traditional molds for concrete floor construction are wooden molds, bamboo molds, steel molds, aluminum alloy molds, etc. Wooden molds and bamboo molds are generally reused about five times, so the use efficiency is low and a lot of wood resources are consumed , causing a large number of forests to be cut down, causing ecological damage and environmental pollution. Steel molds and aluminum alloy molds have a high number of reuses, but their affinity with concrete is too good, and a release agent is required to release the mold, which increases the construction process and labor costs. In addition, the steel mold has a large weight It increases the difficulty of installation, a...
