Description

Thermal insulation of roof structure for building
Technical field
The utility model belongs to building technical field, particularly relates to a kind of thermal insulation of roof structure for building.
Background technology
The present Research of roof insulation provision for thermal insulation is for the heat insulation research of roof insulation, there is traditional construction measure, as water ponding roof, overhead heat insulation plate, planted roof etc., there is a common weak point and be just the increase in roofing loading in these construction measures, in the middle of big-and-middle span roofing, if take these measures to be not desirable selection.Except some above-mentioned construction measures, cast-in-site roof hollowcore slab is exactly from structural point, do not increasing in roof structure loading situation, utilize the air space in hole to reach the object of thermal insulation, but in the middle of the roofing of big-and-middle span, thickness of slab can be made very large according to this measure, selection that neither be desirable.So need to carry out more deep research, combination improvement is carried out to conventional construction way, complex optimum, make " constructing energy-conservation " in the larger effect of the energy-conservation middle performance of building integral.
Although hollow sandwich structure has good mechanical property, but the overall height of hollow sandwich structure is larger than beam and slab structure, structure clear height is caused to reduce, so only use hollow sandwich structure in the middle of the structure of big-and-middle span, just can better embody its advantage for a long time, the form of structure such as the solid floor of cast-in-situ concrete building roof system many uses rib type beam slab or band cap, the former reduces building clear height because of the existence of beam, inconvenience installed by pipeline; The latter is because of from great, and unsuitable large span, large bay, cap is not easy to finishing.Rc Open-web Sandwich Plates structure technology is exactly drawback for overcoming conventional structure form and a kind of new architecture of arising at the historic moment.This structure has that materials are economized, the outstanding features such as little, span ability is large, attractive appearance of conducting oneself with dignity, and obtains large-area engineer applied, achieve economic and social benefit preferably in the past few years.
The traditional construction technique of hollow sandwich structure is applied in the middle of a lot of engineering, its advantage place is shown in a lot, but the construction period of hollow sandwich structure is relatively long, the construction at some position is inconvenient, wherein outstanding any is exactly, when the limited height of hollow sandwich structure, the height of shear connector is very little, so, in the confined space, cast-in-place lower edge floor, shear connector are exactly a cumbersome thing simultaneously, if this problem can be resolved, not only make constructing operation convenient, also the engineering time can be made to shorten.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of thermal insulation of roof structure for building, and the loading characteristic of plate is based on two to flexural deformation, and stabilized structure and easy construction, have excellent thermal and insulating performance.
To achieve these goals, the utility model adopts following technical scheme:
A kind of thermal insulation of roof structure for building, it is characterized in that comprising upper string board rib structure layer, lower edge rib of slab deck, described upper string board rib structure layer assembles shear connector with described lower edge rib of slab deck by steel pipe and is connected, boom plate face insulation layer is set on described lower edge rib of slab deck upper berth, described lower boom plate face insulation layer is connected to described steel pipe assembling shear connector top, described upper string board rib structure layer is provided with above the insulation layer of described lower boom plate face, head insulated layer is provided with between described lower boom plate face insulation layer and described upper string board rib structure layer, waterproofing course is provided with above described upper string board rib structure layer.
The body of wall of described head insulated layer is provided with vent window.
Described lower edge rib of slab deck is formed by the lower boom plate be connected, lower edge rib.
Between described lower boom plate with described lower edge rib, assemble shear connector by described steel pipe between described lower edge rib with described lower edge rib and be connected, and form described lower edge rib of slab deck by fluid concrete.
Described upper string board rib structure layer is formed by connecting by prefabricated strip, precast plate.
Described prefabricated strip with assemble shear connector by described steel pipe between described precast plate, between described precast plate with described precast plate and be connected, and form described upper string board rib structure layer by fluid concrete.
Described steel pipe shear connector is formed by connecting by perforate hexagon connecting nut by top steel pipe, bottom steel pipe, described top steel pipe, described bottom steel pipe have the top shear connector steel tube screw thread, the bottom shear connector steel tube screw thread that match with described perforate hexagon connecting nut, described top shear connector steel tube screw thread is provided with the gripper shoe being fixed on steel pipe periphery, described top, be provided with the top shear connector peg be fixed on the steel pipe of described top above gripper shoe, described bottom shear connector steel tube screw thread has bottom shear connector peg.
The beneficial effects of the utility model are: the cancelled structure after improvement assembles shear connector by wind up floor layer and lower edge floor layer by steel pipe and is formed by connecting, and under vertical uniform load q, cancelled structure main manifestations is the loading characteristic of plate, based on two to flexural deformation; Upper and lower rib of slab deck is based on the press-bending of axle power, stretch bending component; Steel pipe assembling shear connector bears two-way shearing and biaxial bending in a small amount, and the inflection point of moment of flexure is in the centre of shear connector height.Therefore perforate hexagon connecting nut is set at the middle part of steel pipe assembling shear connector and connects its upper and lower two parts, meet the force-bearing situation of structure.The roof of building adopts hollow sandwich structure, between upper and lower rib of slab, form air space, and the thermal resistance of air is maximum in conventional constructional materials, and this adds the entire thermal resistance of building top layer undoubtedly; On the other hand, after roof sun heat radiation enters air space by the rib of slab of upper string board rib structure layer, because the density of hot air is less than cold air, hot air is gathered in the upper part space of air space, along with thermal-radiating increase, the thickness of hot air also corresponding increase in cavity, when the thickness of hot air arrives perforate hexagon connecting nut, to rise from perforate hexagon connecting nut, roofing is discharged on the top entering steel pipe assembling shear connector, therefore decreases and the impact of the lower edge floor layer of indoor exposures by sun heat radiation.Thermal technology's effect of two aspects, improves the thermal and insulating performance of cancelled structure.
