Description

一种装配式复合墙板与外挑复合屋盖自攻钉集块连接构造A connection structure of assembled composite wall panel and external overhanging composite roof with self-tapping nails

技术领域technical field

本实用新型涉及一种装配式复合墙板与外挑复合屋盖自攻钉集块连接构造,属于装配式混凝土建筑结构工程技术领域。The utility model relates to a self-tapping screw aggregate block connection structure of a prefabricated composite wall panel and an overhanging composite roof, belonging to the technical field of prefabricated concrete building structure engineering.

背景技术Background technique

超低能耗房屋的技术研发,国内外工程界一致十分关注。然而目前村镇低多层超低能耗房屋的建造技术,特别是装配式建造技术十分欠缺。现有技术存在的技术瓶颈问题有:(1)传统装配式混凝土剪力墙结构的楼(屋)盖多采用叠合楼盖,其现浇量大、施工周期长,且保温性能差,楼盖与墙体以及楼盖板间接缝处易形成冷桥,难以应用于超低能耗房屋的建造。同时,楼盖接缝处受环境温度以及冻融循环的影响,防水性能难以保证;(2)传统预制混凝土剪力墙和楼(屋)盖钢筋粗、间距大,墙板和楼板的开裂问题较为常见,对建筑防水、保温性能造成较大影响;(3)传统剪力墙钢板与屋盖螺栓连接的技术,不适用内外叶单排钢筋网混凝土薄板夹芯聚苯板墙板与复合屋盖的装配,因为内外叶墙板中间夹着聚苯板且考虑热桥问题,聚苯板不允许打孔穿螺栓,这样采用传统钢板螺栓连接技术难以分别将复合墙板混凝土薄墙板与复合屋盖混凝土薄板装配;(4)自攻钉的价格比螺栓价格低得多,轻钢龙骨结构的冷弯薄壁型钢之间的连接常采用自攻钉连接,自攻钉先后穿透连接的两个轻钢龙骨,轻钢龙骨之间传力通过与自攻钉的咬合实现、没有挤压摩擦力;然而,内外叶单排钢筋网混凝土薄板夹芯聚苯板墙板与复合屋盖的装配,属于钢筋混凝土墙板与复合屋盖的装配,同时需要摩擦力和咬合力,显见目前的自攻钉直接连接轻钢龙骨的技术与复合墙板与复合屋盖的装配及其传力需求有显著不同;(5)传统预制钢筋混凝土屋盖板,多以平板为主,屋盖板在支承端与混凝土梁或剪力墙通过后浇带进行现浇装配,屋盖的挑檐以及散水坡面构造需要在屋盖施工完成后进行,施工周期长、成本高且工程质量难以保证。The technology research and development of ultra-low energy consumption houses has drawn great attention from the engineering community at home and abroad. However, at present, the construction technology of low-storey and ultra-low energy consumption houses in villages and towns, especially the prefabricated construction technology, is very lacking. The technical bottleneck problems existing in the prior art are: (1) The building (house) cover of the traditional prefabricated concrete shear wall structure mostly adopts the laminated floor cover, which has a large amount of cast-in-place, a long construction period, and poor thermal insulation performance. Cold bridges are easily formed at the joints between the lid and the wall and the floor slab, which is difficult to apply to the construction of ultra-low energy consumption houses. At the same time, the joints of the floor are affected by the ambient temperature and the freeze-thaw cycle, so the waterproof performance is difficult to guarantee; (2) The traditional precast concrete shear wall and floor (roof) cover have thick steel bars, large spacing, and cracking of the wall and floor slabs. It is relatively common and has a great impact on the waterproof and thermal insulation performance of buildings; (3) The traditional shear wall steel plate and roof bolt connection technology is not suitable for inner and outer leaf single-row reinforced mesh concrete sheet sandwich polystyrene wall panels and composite houses. For the assembly of the cover, because the polystyrene board is sandwiched between the inner and outer leaf wall panels and the thermal bridge problem is considered, the polystyrene board is not allowed to punch through the bolts, so it is difficult to use the traditional steel plate bolt connection technology to separate the composite wallboard, concrete thin wallboard and composite wallboard. Roof concrete sheet assembly; (4) The price of self-tapping screws is much lower than that of bolts. The connection between the cold-formed thin-walled steel of the light steel keel structure is often connected by self-tapping screws. Two light steel keels, the force transmission between the light steel keels is realized by the engagement with the self-tapping screws, and there is no extrusion friction; however, the inner and outer leaves are single-row reinforced mesh Assembly, which belongs to the assembly of reinforced concrete wall panels and composite roofs, requires friction force and occlusal force at the same time. It is obvious that the current technology of directly connecting light steel keels with self-tapping screws and the assembly of composite wall panels and composite roofs and their force transmission requirements There are significant differences; (5) The traditional prefabricated reinforced concrete roof panels are mostly flat plates. The roof panels and concrete beams or shear walls are assembled in-situ through the post-pouring belt at the supporting end. The slope structure needs to be carried out after the roof construction is completed, and the construction period is long, the cost is high, and the project quality is difficult to guarantee.
