Problems solved by technology

Therefore, the current performance of aerated concrete floor slabs is far from meeting the requirements of buildings for floor slabs, because whether adding beams in the middle of a large span or increasing slab thickness will bring cost, construction and decoration to the building. Adverse effects of
This situation greatly affects the scope of use of aerated concrete floor slabs

specific Embodiment approach

[0011] figure 1 , When the slab is under load, the upper concrete is compressed and the lower reinforcement is tensioned (because the reinforcement is a slender member, it will lose stability when compressed, so the compression of the upper reinforcement cannot be considered), forming a resistance load The bending moment. When the span of the slab increases, the bending moment generated by the load becomes larger, and the section of the slab is also required to resist the bending moment. Although the lower part of the slab can be solved by adding steel bars, if the thickness of the slab is not increased, the compressive stress per unit area above the slab will increase. Due to the low compressive strength of the aerated concrete slab, the compressive stress that can be increased is limited, so the thickness of the slab is not increased and only shorter slabs can be produced.

Abstract

The invention provides a reinforcement method for producing an aerated concrete floor plate. The method is characterized in that a metal rod which can bear a tensile force and a pressing force is arranged at the side of the traditional reinforcing bar so that the floor plate can satisfy long-span force-bearing demands without plate thickness increasing. The reinforcement method greatly widens an aerated concrete floor plate use range. Through use of the aerated concrete floor plate, a building cost is reduced and a building construction speed is improved.

Description

Technical field [0001] The invention belongs to a production method of aerated concrete floor slabs: by changing the traditional reinforcement method in the slab, the length can be increased without increasing the thickness of the slab. technical background [0002] The current aerated concrete floor slab requires the use of the slab in a longer span under the premise that the load conditions are met and the slab thickness cannot be increased. There are technical restrictions on the production of the slab: due to the The compressive strength is low, and the thickness of the plate can only be increased in order to avoid excessive reinforcement when adding reinforcement. Therefore, manufacturers can only provide products limited to a certain range of lengths for plates whose thickness requirements are limited to a certain range. The current manufacturer of aerated concrete slabs provides floor slabs: even if the thickness of the slab reaches 200 mm, it can only produce slabs with ...
