Detailed description of the invention
Embodiment is shown in Figure 1; this Ventilating for roof hole structure; comprise deck 1, leveling layer 2, waterproofing course 3, insulation layer 4, heat insulation protecting layer 5, roof decorations layer 6 and ventilating device for roof that roofing connects from the bottom to top successively, the concrete protection 9 that described ventilating device for roof comprises permeability cell 7, covers on the large diameter protecting tube 8 outside this permeability cell 7 and have in the protecting tube 8 of template action.
Described concrete protection 9 and the concrete of heat insulation protecting layer 5 are integrated builds shaping or split and builds shaping.The anti-down fixing reinforcing bar 13 be integrated with the colligation of heat insulation protecting layer built-in cracking resistance steel mesh reinforcement 12 is embedded with in described concrete protection 9; anti-down fixing reinforcing bar 13 is in L-type; upward, transverse part and the colligation of heat insulation protecting layer built-in cracking resistance steel mesh reinforcement 12 are fixed, and are at least evenly arranged four in each protecting tube in vertical part.
Described permeability cell 7 is made up of perpendicular section 7.1, half corner bevelling linkage section 7.2 and declivity section 7.3, can be three sections of pvc pipe that field joint connects or one section of pvc processing for fire bending manages.The bottom of described perpendicular section 7.1 has at least one group of hole 10 of breathing freely, if formed by integrally casting is shaping, the absolute altitude of ventilative hole 10 must not, higher than the bottom of heat insulation protecting layer 5, prevent concrete from entering permeability cell; If split is built shaping, the absolute altitude of ventilative hole 10 must not higher than the built-in cracking resistance steel mesh reinforcement of heat insulation protecting layer, and the bottom of perpendicular section 7.1 is surrounded by anti-blocking non-woven fabrics 15, and this anti-blocking non-woven fabrics 15 extends the upside of overlap joint to insulation layer 4 from pipe shaft bottom outside; The mouth of pipe absolute altitude of described declivity section 7.3 with land used amount of precipitation is adapted, the termination of declivity section 7.3 overlaps the Dense mesh screen 14 having anti-gray in advance.
Described protecting tube 8 is pvc pipe or steel drum, and the tip position of corresponding declivity section 7.3 has ventilation mouth 8.1, is filled with sealing cement 11 in the outside of protecting tube 8 and the gap of roof decorations layer 6 link position.
Gas permeable devices can be placed in roofing partitioning slot junction.If air hole is constructed prior to partitioning slot, note the protection with partitioning slot connecting portion should adopting the material plugging separating seams such as non-woven fabrics, ensure the connectedness of partitioning slot.
In the present embodiment, protecting tube is that 500mm is long, diameter is the pvc pipe of 300mm, the pvc pipe of permeability cell to be diameter be 50mm, and Specific construction step is as follows:
Step one, the processing of protecting tube and permeability cell and making: protecting tube adds man-hour, otch should be put down, directly, can on-the-spot process;
Step 2; construction location: deck, leveling layer, waterproofing course, insulation layer, heat insulation protecting layer, the roof decorations layer of construction roofing; it is particularly to be noted that; when laying the built-in cracking resistance steel mesh reinforcement of heat insulation protecting layer; anti-down fixing reinforcing bar and steel mesh reinforcement colligation are fixed, under reinforcing bar need being placed in reinforced mesh time fixing, and evenly places; to ensure the fastness of gas permeable devices, gas permeable devices is positioned over the junction of partitioning slot.
Step 3, Assembling is with fixing: good for processing and fabricating permeability cell is fixed on partitioning slot and joins position, the bottom of permeability cell needs to contact with waterproofing course.For preventing air-vent from being blocked by concrete, non-woven fabrics can be adopted to wrap up in bottom, and to overlap 200mm wide with warming plate; Top adopts tied silk to be fixed on fixing reinforcing bar, the phenomenon such as not run-off the straight disengaging during to ensure concreting.
Step 4, concreting: when building concrete protection, is placed in permeability cell outside by protecting tube, bottom need and reinforced mesh interval more than 20mm, avoid reinforced mesh intake corrosion.
The concrete of concrete protection and heat insulation protecting layer is split when building, and needs before building concrete protection, heat insulation protecting layer is carried out dabbing, cleans out rear wettability treatment.
In construction it is to be noted that
According to actual needs such as durations, protecting tube can not be removed, also can according to designing requirement, and the selected color coordinated mutually with architectural surface, shortens construction period; If field condition and duration allow, protecting tube pipe, by being vertically divided into two parts, adopts reinforcing bar etc. to be made into circular, hoop, recycling.
During construction roof decorations surface layer, the ointment that encapsulant can use 10mm wide or other closed materials, avoid base portion to intake.
When the concrete of concrete protection and heat insulation protecting layer is integrated and builds, same intensity concreting should be adopted; The concrete of concrete protection and heat insulation protecting layer is split when building, and according to designing requirement, can select the concreting of different brackets.The height of working procedure, permeability cell according to actual needs, can be made corresponding adjustment by other types roofing construction.
