Description

Double-ventilating light type roofing broad

The invention belongs to a kind of heat insulation method and the member thereof of construction work roofing.

The existing aeration type roofing large board member (patent No.: 89204818.2) be the roofing element of a kind of " grillage unification ", the mechanism of its ventilating heat-proof or heating, temperature keeping is to utilize the large board member convection current of air of winding up in the doubling plate face interlayer to absorb and discharge roofing heat energy at sunshine, plan reach carry out to this heat energy of outdoor discharging summer heat insulation, the purpose that heat to this heat energy of indoor discharging winter.

A large amount of facts have proved, it is fine that this large board member summer is carried out heat insulation effect to outdoor discharging roofing heat energy at sunshine, but close the upper face vent winter, open lower face to indoor vent to indoor discharging roofing heat energy at sunshine, it is then very poor to carry out indoor effect of heating, this is because the air of being heated in the interlayer is lighter, can only accumulate in eminence in the plate, be difficult to flow downward, therefore, do not reach the effect of heating indoor.

Detailed actual measurement also proves, in summer, except discharging the heat energy at sunshine of roofing, simultaneously also want drain chamber internal cause body of wall to be subjected to sunshine and to the heat energy of indoor radiation, these heat energy in fact also all are collected at indoor eminence, as if can be in the highest point of indoor roofing be set up a kind of drain chamber the device of heat energy, opened its summer, close winter, will produce the effect of heat insulation reduction room temperature in better summer, and don't influence indoor insulation in winter.In addition, because the plate face of former aeration type roofing large board member can not be exploited the light skylight, therefore can not demandingly stride greatly, use in the continuous span building in daylighting.

Purpose of the present invention is exactly to change the simple function that former aeration type roofing large board member can only discharge roofing heat energy at sunshine, make it to become and to discharge roofing heat energy at sunshine, can discharge body of wall again because of being subjected to the heat energy of sunshine, become large board member with bilateral wind function to indoor radiation.Simultaneously, when building is bigger because of span, or during the daylighting of multispan continuous to-be roofing, above-mentioned bilateral wind structural system also wants to satisfy simultaneously the multi-functional requirement as the roof light use.

The concrete practice of the present invention is: the upper string board face of the roofing large board member of " grillage unification " is made double-deck, that is: top plate face 1 and lower plywood face 2.The distance of upper and lower two-ply face equals the vertical air channel 4 that helps an interlayer of height (about 20-50cm) formation of 3 of this large board member, establish the fresh air inlet 5 in this air channel at the plate pin place of large board member, on the upper and lower two-ply face at plate ridge place, all have exhaust vent 6,7 upwards simultaneously to outdoor air draft.Because of the plate face all will be reinforced with horizontal helping around the practice hole after punching routinely, for guaranteeing the needs of hole to outdoor unidirectional air draft, the reinforcing of this hole is horizontal to help 8,9 all should be to be retrousse form on the top of plate face, but turn over horizontal 9 the height that helps in the reinforcing of lower face hole, can not block the outlet in air blanketing air channel 4 because of it, so this is horizontal to help 9 the height should not be greater than 1/2 band height, as shown in Figure 4, or make 8,9 dislocation are arranged, as Fig. 1,2, shown in 3, so that the air that has guaranteed to be heated in the roofing interlayer can be from horizontal upper notch 6 ' discharge the smoothly roofing that helps.13 ' be the protective cover plate of upper face exhaust vent 6, can be concrete plate or tin plate are made.The exhaust vent 7 of lower face is offered for getting rid of indoor heat energy.This exhaust vent 7 can make open type in the hot area, and as shown in Figure 1, the annual unlatching do not add control nature bilateral wind; Owing to indoor the insulation requirement arranged winter, the exhaust vent 7 of lower face can not make open type, should be able to close during winter, can add movable sealing cover 10 on this exhaust vent 7 in temperate zone area, as shown in Figure 2, so that can close before winter.Or on exhaust vent 7 installation shaft flow fan 11, and add pneumatic removable cover 12 on blower fan top, as shown in Figure 3, summer or when needing indoor exhaust wind axial flow blower 11 start, pneumatic removable cover 12 is blown open and is ventilated under the effect of blast, and winter, when not needing air draft (or) axial flow blower 11 was closed, and did not have blast this moment, pneumatic removable cover 12 falls by deadweight, closes exhaust vent 7 automatically and is incubated.

When roofing needs daylighting, can enlarge bore size again at the exhaust vent periphery of upper and lower laminate face, form roof light, this bilateral wind system and roof light are merged, form a kind of double-ventilating light type roofing broad that has, shown in Fig. 4,5,6.At this moment, the protective cover plate 13 of the exhaust vent 6 of top plate face is to make with the material of light-permeable, if can be glass fiber reinforced plastic, organic glass or the lower plywood face of glass window formula is located at air outlet 7 open type natural ventilations in the light inlet window scope, as shown in Figure 4, then can not add topped processing; If seasonal unlatching, then on exhaust vent 7, add movable sealing cover 10, as shown in Figure 5, also should make by light transmissive material; If carry out controlled bilateral wind with axial flow blower, then also installation shaft flow fan 11 and pneumatic removable cover 12 equally on exhaust vent 7, as shown in Figure 6.

The big plate of roofing of the present invention can be that lower edge is a pull bar, wind up and be the big plate of two-hinged arch formula roofing of shaped form, polygon, triangular plate face, or be equipped with the truss type roof boarding by means of web member between lower chord and upper string board face, or the plate face is shaped form, broken line shape, the whole frid of leg-of-mutton real abdomen.

Key technology of the present invention be turn on the lower face exhaust vent reinforce cross rib be provided with the position and on turn over the design of height.Because this cross rib is sitting at the exit in plate face interlayer air channel, if the improper convection current that will have a strong impact on air in the interlayer air channel is set.Therefore, when the reinforcing cross rib of upper and lower laminate face exhaust vent during at same vertical line, turning over the height of reinforcing cross rib 9 on the lower plywood face can not be greater than 1/2 of interlayer air channel height, preferably not on same vertical line, take dislocation to arrange, with increase exhaust vent 6 ' size, when merging with roof light, the perforate of plate face is very big, to cut apart with increase horizontally help 9 ' way dwindle bore size, so that installation light transmissive material and vertical rib 3 carried out cross binding avoids vertical rib 3 in this interval side unstability.
