Embodiment Construction

[0040] A construction method for LPM light-weight filling embodying poured concrete hollow floors. The LPM light-weight filling body is mainly filled with self-extinguishing flame-retardant lightweight porous material—polyphenylene foam, with reinforcement and isolation layers outside; The material is wrapped with an isolation layer for protection and waterproofing, and a reinforcement layer is set on the top or bottom surface to resist construction and floating loads;

[0041] The construction method includes the following steps:

[0042] (1) Formwork for supporting the bottom of the slab

[0043] The bottom formwork of the hollow floor is made of 15mm multi-layer board, the secondary keel is made of 40mm×90mm wooden square, the main keel is made of 48mm×3.2mm double steel pipes, and the support adopts the fastener type steel pipe full house scaffold system. Adjust the top support; when the span of the slab is ≥ 4m, the top slab must be arched, and the height of the arch is ...

Abstract

The invention discloses an on-site concrete hollow floor construction method of LPM light filling embodies. The construction method comprises the steps that a plate bottom formwork is erected, plate bottoms and hidden rib beam steel bar binding cushion blocks are installed, anti-floating drilling is conducted; and plate bottoms and hidden rib beam steel bars are bound, and a specially-assigned person is dispatched to punch holes in the bottom plate template according to the anti-floating distribution diagram, install water and electric pipelines, hoist LPM light filling pieces, place the filling pieces, bind plate surface reinforcing steel bars, reinforce anti-floating iron wires of the filling pieces, pour concrete, maintain, demold and the like. The method is simple in process, convenient to construct and easy to operate; by the adoption of the technology in a proper structure, the engineering quality is guaranteed, and meanwhile the beneficial effects of being small in concrete consumption, large in space, low in structural self-weight, small in earthquake acting force, good in structural heat insulation and sound insulation performance, capable of shortening the construction period and the like are achieved.

Description

technical field [0001] The invention relates to a construction method of a concrete hollow floor with LPM lightweight filling. Background technique [0002] In modern architecture, vigorously promoting green construction is an important strategy to solve my country's resource and energy problems. However, the existing construction methods of cast-in-place concrete hollow floors cannot meet the requirements of green construction and need to be further improved. Contents of the invention [0003] The object of the present invention is to provide a construction method of LPM light-weight filled embodied poured concrete hollow floor with simple process, convenient construction and easy operation. [0004] Technical solution of the present invention is: [0005] A construction method for LPM light-weight filling embodying poured concrete hollow floors, characterized in that: the LPM light-weight filling body uses self-extinguishing flame-retardant lightweight porous material—...
