Abstract

The utility model belongs to a roofing member of construction engineering. The upper chord plate surface of a roofing large plate member united by plates and racks is made into double layers, a cornice of the double-layer plate surface is provided with a wind inlet hole, and wind outlet holes for exhausting wind towards outdoors are arranged on plate ridges on the double-layer plate surface. The wind outlet hole on an upper layer plate surface causes air convection in the double-layer plate surface to drain roofing sunshine heat energy through the wind inlet hole, and the wind outlet hole on a lower layer plate surface drains the heat energy which is radiated into a room because of the sunshine of walls. A double-ventilation system can also be merged with a lighting skylight, and a double-ventilation lighting system is formed. The utility model is especially suitable for wide-span buildings needing heat insulation, temperature reduction and roof lighting.

Description

Double-ventilating light type roofing broad

This novel a kind of heat insulation method and member thereof that belongs to the construction work roofing.

Existing aeration type roofing large board member (patent No. 89204818.2) is 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 in striding greatly of having relatively high expectations of daylighting, continuous span building, use.

This novel purpose 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.

This novel concrete practice is: the upper string board face of roofing large board member that will " grillage unification " makes bilayer, 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 the natural bilateral wind in control ground; 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, can be glass fiber reinforced plastic, organic glass or glass window formula.If the lower plywood face is located at the interior air outlet 7 open type natural ventilations of 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.

This novel big plate of roofing can be that lower edge is a pull bar, winds up to be the big plate of two-hinged arch formula roofing of shaped form, polygonal, triangle template face; Or between lower chord and upper string board face, be equipped with the truss type roof boarding by means of web member; Or the plate face is shaped form, broken line type, the whole frid of leg-of-mutton real abdomen.

This novel key technology 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,, turn on the lower plywood face and reinforce cross rib 9 height and can not preferably not on same vertical line, take dislocation to arrange greater than 1/2 of interlayer air channel height when the reinforcing cross rib of upper and lower laminate face exhaust vent during at same vertical line, with increase exhaust vent 6 ' size.When merging with roof light, the perforate of plate face is very big, with increase cut apart cross rib 9 ' way dwindle bore size so that light transmissive material is installed and vertical rib 3 is carried out cross binding, avoid vertical rib 3 in this interval side unstability.

Below in conjunction with drawings and Examples this novel double-ventilating light type roofing broad is further described:
