Description

A kind of surface cuts molding haydite concrete prefabricated panel

Technical field

The utility model relates to a kind of lightweight wall plates, in particular to a kind of to be applied to plate face process in building industrialization field Cut molding haydite concrete prefabricated panel.

Background technique

From the beginning of this century by the way that it is big to have filled wall in traditional concrete structure since popularizing " it is viscous to prohibit real limit " policy in an all-round way It mostly uses building block instead of clay solid brick, achieves certain resource-effective effect, construction weight also has a degree of drop It is low, but since filling wall still falls within masonry structure component, thus its globality is poor, in all previous devastatingly earthquake centre filling wall Earthquake such as right-angled intersection shearing crack is still one of Typical Seismic Damage, although taking the earthquake resistant constructions such as ring beam and construction column, simultaneously The generation of this earthquake is not solved fundamentally.On the other hand, collapse in order to avoid outer dodge occurs in earthquake for filling wall, it is existing Necessary connection measure must be taken by defining in each specification of row or regulation between masonry filler wall and main structure, such as embedded to draw Muscle or paving reinforced mesh etc. are tied, filling wall so must be taken into consideration again to the stiffness contribution of main structure especially frame, increase Geological process has scholar to propose the method for adding in the work progress of blockwork horizontal and vertical flexible separating layer, has Effect reduces blockwork to the stiffness contribution of chassis body, but also increases working procedure simultaneously, claim for eot, and traditional Building construction quality is difficult to be effectively ensured.As long as there is two at all as it can be seen that still using traditional live building construction method Property problem: the duration is longer, and construction quality is unable to absolute guarantee, and then results in filling wall to the shock resistance of concrete main body structure Can influence cannot basic effective solution.And concrete structure house represents building skill using " manufacture " mode of prefabrication and assembly construction A kind of advanced developing direction in art field.

To solve the problems, such as above-mentioned masonry panel, start that prefabricated non-load bearing partition is widely used in building industrialization field Plate, as plant fiber strengthens plate, air entraining cement plate, Ceramsite concrete slab, clinker powder coal ash plate, flyash stone cement plate, stone Cream plate etc..It is that chemical raw material and ingredient are made into that plant fiber, which strengthens plate, easy to aging, easy to crack, the service life is short, and to the cold, heat holds It is easily-deformable, 1-3 natural separation is connect with concrete construction；Air entraining cement plate water absorption rate is high, and it is easy to crack de- to paste ceramic tile stone material It falls, and cannot follow closely, bore and horizontal, longitudinal threading；Ceramsite concrete slab, clinker powder coal ash plate, the water suction of flyash stone cement plate Rate is high, and easy to crack, overall structural strength is low, and shock resistance, bend resistance load are low；Plasterboard water absorption rate is strong, and contacting with water will lead to Gypsum decomposes, and the places such as kitchen, toilet cannot use, and can not paste ceramic tile, stone material etc., application range is by the very day of one's doom System.There is also a common problems for above-mentioned prefabricated panel, i.e., the floating ash of surfaces of wall is seriously and coat of plaster is easy to crack falls off, seriously It influences to use, or even is restricted in some places.

In view of this, institution of higher education of Anhui Province physicism project (KJ2015A336) and institution of higher education of Anhui Province people Literary social sciences research project (SK2015A678) has made intensive studies ceramsite concrete wall panel, there is this case generation then.
