装配式内置保温层混凝土复合墙-轻钢框架连接节点Prefabricated built-in insulation layer concrete composite wall-light steel frame connection node

本实用新型属于建筑结构工程中墙体连接节点制作技术领域,具体涉及一种装配式内置保温层混凝土复合墙-轻钢框架连接节点及作法。The utility model belongs to the technical field of wall connection node production in building structure engineering, in particular to an assembled concrete composite wall-light steel frame connection node with a built-in thermal insulation layer and a method thereof.

背景技术:Background technique:

当前我国正处于城镇化的快速进程中,到2020年实现“全面小康”,城镇化水平达到60%左右,城镇人口约增加3亿,城镇化住宅建设数量将在较长时间内保持较高水平。然而,目前的新增建筑仍以传统的高能耗、高污染的粗犷型建筑方式建造。推进建筑工业化、住宅建筑产业化,是实现住宅建设方式由粗放型向集约型转变、提高住宅质量和节约住宅能耗的重大举措,是保证建筑业可持续发展的重要途径,对我国经济及社会发展有着极其深远的意义。At present, my country is in the rapid process of urbanization. By 2020, it will achieve "all-round well-off", the urbanization level will reach about 60%, the urban population will increase by about 300 million, and the number of urbanized housing construction will remain at a relatively high level for a long time . However, the current newly added buildings are still built in the traditional rough building method with high energy consumption and high pollution. Promoting the industrialization of construction and housing construction is a major measure to realize the transformation of housing construction from extensive to intensive, improve housing quality and save housing energy consumption, and is an important way to ensure the sustainable development of the construction industry. Development has extremely far-reaching meanings.

轻钢框架结构指由小截面的热轧H型钢、高频焊接H型钢、普通焊接H型钢或异形截面型钢、冷轧或热轧成型的钢管等构件组成的纯梁柱框架结构或梁柱框架-支撑结构体系,具有结构施工简单、拆装便捷、布局灵活的特点。发展装配式轻钢框架结构,可实现构件预制,现场安装,能够有效节约资源、降低能耗,同时极大缩短了施工时间,对实现建筑工业化和住宅产业化以及城镇化建设具有极大地促进作用。Light steel frame structure refers to a pure beam-column frame structure or beam-column frame composed of small-section hot-rolled H-shaped steel, high-frequency welded H-shaped steel, ordinary welded H-shaped steel or special-shaped section steel, cold-rolled or hot-rolled steel pipes, etc. - The supporting structure system has the characteristics of simple structural construction, convenient disassembly and assembly, and flexible layout. The development of prefabricated light steel frame structure can realize component prefabrication and on-site installation, which can effectively save resources, reduce energy consumption, and greatly shorten the construction time, which greatly promotes the realization of building industrialization, housing industrialization and urbanization. .

梁柱作为主体结构,在装配式结构技术上已经较成熟,但与之配套的装配式墙板结构体系研究却相对滞后。考核装配式结构工业化水平的重要指标之一就是墙板的装配化程度,墙板与主体框架的装配连接形式的不同,对主体结构的刚度存在较大的影响,不合理设置甚至会导致主体结构的破坏。已有装配式墙板多为装配式外挂墙板,多作为结构的外围护构件,不对主体结构提供刚度及承载力,相反,外挂墙板具有一定质量,增加了结构受力构件的重力荷载,从而增加了主体结构的设计强度及工程造价。As the main structure, beams and columns are relatively mature in prefabricated structure technology, but the research on the supporting prefabricated wall panel structure system is relatively lagging behind. One of the important indicators for assessing the industrialization level of the prefabricated structure is the degree of assembly of the wall panels. The difference in the assembly connection form of the wall panels and the main frame has a great influence on the stiffness of the main structure, and unreasonable settings may even lead to the main structure. destruction. Most of the existing prefabricated wall panels are prefabricated external wall panels, which are mostly used as the outer protective components of the structure, and do not provide rigidity and bearing capacity for the main structure. On the contrary, the external wall panels have a certain quality, which increases the gravity load of the structural members. , thereby increasing the design strength and engineering cost of the main structure.

如何较为可靠的实现装配式墙体与轻钢框架上梁柱的连接问题,从而使墙板成为结构受力构件的问题一直没有得到很好的解决,是发展和推广应用装配式结构住宅建筑体系中亟待解决的问题,也是造成装配式结构房屋体系不能大量推广的重要原因。How to reliably realize the connection between the prefabricated wall and the upper beam and column of the light steel frame, so that the problem of making the wall panel a structural component has not been well resolved. It is the development and promotion of the prefabricated residential building system. The problem that needs to be solved urgently is also an important reason why the prefabricated structure housing system cannot be widely promoted.

与现有技术相比,本实用新型的装配式内置保温层混凝土复合墙-轻钢框架连接节点具有如下优势:Compared with the prior art, the assembled concrete composite wall-light steel frame connection node with built-in thermal insulation layer of the utility model has the following advantages:

(1)墙板参与结构受力,提高结构抗震性能。现有装配式建筑普遍采用外挂式墙板,墙板仅作为结构的外围护构件,不对主体结构提供刚度及承载力,相反,外挂墙板具有一定质量,增加了结构受力构件的重力荷载,从而增加了主体结构的设计强度及工程造价。而本实用新型墙板的内置保温层与内页混凝土嵌入框架内,与框架梁柱相互传递荷载,可以作为受力构件,参与主体结构受力,为主体结构提供刚度及承载力,提高结构的抗震能力,降低梁柱构件的设计强度及成本。(1) The wall panel participates in the stress of the structure and improves the seismic performance of the structure. Existing prefabricated buildings generally use external wall panels. The wall panels are only used as the outer protective components of the structure, and do not provide rigidity and bearing capacity for the main structure. On the contrary, the external wall panels have a certain quality, which increases the gravity load of the structural members. , thereby increasing the design strength and engineering cost of the main structure. However, the built-in insulation layer and the inner page concrete of the wallboard of the utility model are embedded in the frame, and transmit loads with the beams and columns of the frame, which can be used as a force-bearing member to participate in the stress of the main structure, provide stiffness and bearing capacity for the main structure, and improve the stability of the structure. Anti-seismic ability, reduce the design strength and cost of beam-column components.

(2)强节点构造,提供安全可靠的装配式连接。内置保温层四周混凝土边框加强及边框钢筋网加密的设计,保证了墙板四周强度,进而保证了墙体-框架连接节点的强度,使墙板与框架柱之间传递荷载时,不至于墙板边缘提前开裂,影响墙体受力性能。连接螺栓预埋在墙板四周的混凝土边框内,与墙板牢固连接;连接角钢焊接在轻钢框架柱、轻钢框架梁上,连接件与框架可靠连接;最后,墙板与轻钢框架柱通过连接螺栓及连接角钢紧密栓接,从而实现装配式墙板与主体框架的牢固装配。(2) Strong node structure, providing safe and reliable assembly connection. The reinforced concrete frame around the built-in insulation layer and the dense design of the frame steel mesh ensure the strength around the wall panels, thereby ensuring the strength of the wall-frame connection joints, so that when the load is transferred between the wall panels and the frame columns, the wall panels will not be damaged. The edge cracks ahead of time, which affects the mechanical performance of the wall. The connecting bolts are pre-buried in the concrete frame around the wall panels and are firmly connected with the wall panels; the connecting angle steel is welded on the light steel frame columns and light steel frame beams, and the connectors are reliably connected with the frame; finally, the wall panels and the light steel frame columns Through the tight bolting of the connecting bolts and the connecting angle steel, the firm assembly of the prefabricated wall panel and the main frame is realized.

(3)降低框架梁柱钢材腐蚀,提高结构防火性能。外页混凝土外包住钢框架梁柱,使钢框架梁柱与外界隔离,降低钢材腐蚀,同时,混凝土具有很好的防火效果,可以弥补钢框架结构防火能力差的劣势。(3) Reduce the corrosion of frame beams and columns and improve the fire performance of the structure. The outer concrete covers the beams and columns of the steel frame, which isolates the beams and columns of the steel frame from the outside world and reduces the corrosion of steel. At the same time, the concrete has a good fire prevention effect, which can make up for the disadvantage of the steel frame structure's poor fire resistance.

(4)整体性好,结构保温一体化。墙板内外页混凝土与发泡混凝土边框一起,为墙板形成强度较高的发泡混凝土外壳,以减轻中部内置保温层对墙板强度的削弱,提高构件强度。将内置保温层置于混凝土结构板中部,使易燃的保温材料与外界隔离,保温防火效果好。(4) Good integrity, integrated structure and heat preservation. The concrete on the inner and outer pages of the wall panel and the foamed concrete frame together form a high-strength foamed concrete shell for the wall panel to reduce the weakening of the wall panel's strength by the built-in insulation layer in the middle and improve the component strength. The built-in thermal insulation layer is placed in the middle of the concrete structural slab to isolate the flammable thermal insulation material from the outside, and the thermal insulation and fire prevention effect is good.

(5)本实用新型墙板在工厂大模块化生产预制,制作简易,容易在流水线上实现高效率工业化制作。同时,大模块化墙板便于施工现场装配式安装,安装节点少且牢靠,施工简单,显著降低工人作业强度,减少工程用工量,同时高效缩短工程现场施工时间,适合于在实际工程中广泛推广应用。(5) The wall panel of the utility model is prefabricated in a large-scale modular production in a factory, which is easy to manufacture and can be easily industrialized with high efficiency on the assembly line. At the same time, the large modular wall panel is convenient for prefabricated installation on the construction site, with few and reliable installation nodes, simple construction, significantly reduces the work intensity of workers, reduces the amount of engineering labor, and at the same time efficiently shortens the construction time of the project site, which is suitable for widespread promotion in actual projects. application.
