Description
Technical field
The utility model relates to a kind of arch heat-insulated roof concrete plate.
Background technology
Reinforced concrete member due to concrete tensile strength and ultimate tensile strength value all very low, so under service load effect, normally work with cracking.Thus to using the component not allowing to ftracture, the intensity of tensile reinforcement can not be made full use of.In order to meet distortion and the requirement of Crack Control, then need the sectional dimension and the steel using amount that increase component, this will cause conducting oneself with dignity excessive, make reinforced concrete structure become impossible or very uneconomical for large span or the structure of bearing dynamic loading.
Prestressed reinforced concrete construction refers to and applies compressive stress in advance to the tensile region of concrete or reinforced concrete beam, the size of this stress and the regularity of distribution, the tensile stress produced under being conducive to offsetting service load effect, thus concrete component unlikely cracking under service load effect is made, or postpone cracking, or crack width is reduced, contribute to the crack resistance improving component, improve the stress performance of component, material can be saved simultaneously and alleviate dead load.It is according to the bonding situation between prestressed reinforcement and concrete, be divided into bonded prestressed concrete structure and unbonded prestressed concrete structure, wherein, bonded prestress concrete plate is as a kind of new structure technology, compared with non-adhesion prestressed concrete plate, there is the advantages such as structural safety is high, good endurance, saving steel and be widely used.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of structure arch heat-insulated roof concrete plate simple, heat insulation and easy for installation.
For solving the problem, the utility model adopts following technical scheme:
A kind of arch heat-insulated roof concrete plate, comprise concrete plate and connector, groove is provided with bottom described concrete plate, the both sides of described concrete plate are provided with extension block, described concrete intralamellar part comprises horizontal steel bar, longitudinal steel bar and cement sand bed, described horizontal steel bar is provided with one or more, described horizontal steel bar and concrete plate fix, described longitudinal steel bar is provided with two, described longitudinal steel bar runs through horizontal steel bar, and fix with horizontal steel bar, described cement sand bed is positioned at the top of concrete plate, described cement sand bed covers horizontal steel bar and longitudinal steel bar, described cement sand bed is provided with cementitious coating, it is bonding that described cementitious coating is positioned at cement sand bed, described connector is positioned at the both sides of concrete plate, and with extension block Joint.
As preferably, described concrete plate both sides are arranged for sloping inwardly 15 °, are conducive to fixing with connector tabling.
As preferably, described groove is that arch is arranged, and is conducive to the support force strengthening concrete plate, avoids concrete plate to rupture.
As preferably, described horizontal steel bar and longitudinal steel bar form steelframe, are conducive to the intensity strengthening concrete plate.
As preferably, described steelframe is provided with steel wire.
As preferably, described cement sand bed parcel steelframe, can the hardness of reinforced cementitious screed, prevents cement mortar fault rupture simultaneously.
As preferably, the thickness of described cementitious coating is 1cm, concrete plate can be made harder by the thickness of cementitious coating, and cracking situation reduces.。
As preferably, described connector is that bucking ladder is arranged, and is conducive to being connected with concrete plate, and is conducive to percolation-proof.
The beneficial effects of the utility model are: owing to being provided with groove, support force can be strengthened, owing to being provided with horizontal steel bar and longitudinal steel bar and forming steelframe, the toughness of concrete plate can be strengthened, prevent fracture at random, owing to being provided with cementitious coating, be conducive to preventing concrete plate face checking, owing to being provided with connector, concrete plate and concrete plate can be bonded mutually, and can percolation-proof.
