Description

桁架组合梁与上下层连接的轻钢结构及其施工方法 Light steel structure connecting truss composite beam with upper and lower layers and construction method thereof

技术领域Technical field

本发明涉及一种轻钢结构及其施工方法，特别是一种用于轻钢龙骨体系房屋中的轻钢结构及其施工方法。 The invention relates to a light steel structure and a construction method thereof, in particular to a light steel structure used in a house of a light steel keel system and a construction method thereof.

背景技术Background technique

轻钢龙骨房屋体系具有质量轻、抗震性能好、墙体厚度小、保温隔热性能好、施工污染小、施工速度快、无需支摸板、管线布置方便、残生废弃物少、能促进节能环保、可工厂化生产和可促进建筑产业发展的优点，因此近年来在国内外建筑行业中得到了广泛的应用。Light steel keel house system has light weight, good seismic performance, small wall thickness, good thermal insulation performance, low construction pollution, fast construction speed, no need for supporting plates, convenient pipeline layout, less residual waste, and can promote energy saving and environmental protection. In recent years, it has been widely used in the construction industry at home and abroad in terms of factory production and the advantages of promoting the development of the construction industry.

在目前的轻钢龙骨房屋体系中，墙体承重桁架和桁架组合梁采用两种做法：1、传统的C型冷弯薄壁型钢承重桁架和桁架组合梁，即是由截面为C型冷弯薄壁型钢通过自攻螺丝连接而成的墙体承重桁架和桁架组合梁；这种做法的缺点是，由于C型冷弯薄壁型钢截面腹板和翼缘的宽度比较大，在轴向荷载作用下易发生局部屈曲而降低构件承载力。2、闭合方矩型冷弯薄壁型钢承重桁架和桁架组合梁，即是由截面为闭合方矩型冷弯薄壁型钢通过标准连接件用自攻螺丝连接而成的墙体承重桁架和桁架组合梁；这种做法的优点是由于方矩型管为闭合式钢管，所以在轴向荷载作用下不易发生局部屈曲，承载力高。In the current light steel keel house system, the wall load truss and truss composite beam adopts two methods: 1. The traditional C-type cold-formed thin-walled steel load-bearing truss and truss composite beam, that is, the section C-shaped cold-bending Thin-walled steel is a wall-bearing truss and truss composite beam connected by self-tapping screws; the disadvantage of this approach is that the axial load is relatively large due to the width of the C-shaped cold-formed thin-walled steel section web and flange. Local buckling is likely to occur under the action to reduce the bearing capacity of the member. 2. Closed square-shaped cold-formed thin-walled steel load-bearing truss and truss composite beam, which is a wall-bearing truss and truss made of self-tapping screws connected by standard joints with closed-section rectangular cold-formed thin-walled steel. Composite beam; the advantage of this method is that since the rectangular tube is a closed steel tube, local buckling is less likely to occur under axial load and the bearing capacity is high.

目前的轻钢龙骨房屋体系具有以下几点缺点：1、在轻钢龙骨房屋体系的每一层墙体承重桁架均包括墙体片柱、连接在墙体片柱的上部之间的上连接管、以及连接在墙体片柱的下部之间的下连接管，桁架组合梁中的楼面梁的上弦杆直接搁置在下层墙体承重桁架的上连接管上，而上层墙体承重桁架的下连接管又压在楼面梁的上弦杆上。这种结构的楼面梁无法同时与上下层墙体承重桁架直接连接，只能是楼面梁的上弦杆任意搭在下层墙体承重桁架的上连接管上，所以虽然安装方便，但不牢固，同时楼面梁的局部承压不易满足受力要求，楼面梁具有承载力弱、稳固性差的缺点，并且，楼面梁直接搭在下层墙体承重桁架的上连接管上的话，由于连接管将直接承受楼面梁及上层载荷，所以容易造成楼面梁、连接管和楼面板发生颤动及变形，并由此破坏楼面装饰层，产生不安全感。The current light steel keel house system has the following shortcomings: 1. Each wall of the light steel keel house system has load-bearing trusses including wall columns and upper connecting pipes connected between the upper parts of the wall columns. And a lower connecting pipe connected between the lower portions of the wall columns, the upper chord of the floor beam in the truss composite beam is directly placed on the upper connecting pipe of the lower wall load truss, and the upper wall is under the load truss The connecting tube is pressed against the upper chord of the floor beam. The floor beam of this structure cannot be directly connected to the upper and lower wall load-bearing trusses at the same time. Only the upper chord of the floor beam can be arbitrarily placed on the upper connecting pipe of the lower wall load-bearing truss, so although it is convenient to install, it is not strong. At the same time, the partial pressure of the floor beam is not easy to meet the stress requirements, and the floor beam has the disadvantages of weak bearing capacity and poor stability. Moreover, if the floor beam is directly placed on the upper connecting pipe of the lower wall load-bearing truss, due to the connection The pipe will directly bear the floor beam and the upper layer load, so it is easy to cause the building beam, the connecting pipe and the floor panel to vibrate and deform, and thereby damage the floor decorative layer, resulting in insecurity.

2、闭合方矩型冷弯薄壁型钢桁架组合梁杆件的连接方式为焊接、螺栓连接或自攻螺丝连接等。焊接是冷弯薄壁型钢桁架杆件之间的第一种直接连接方式，尽管这种连接方式承载力大、不需要接点板，但焊接工作量大，费工，且由于钢桁架杆件截面较薄，焊接操作十分不便，焊接质量难以得到保证；通过节点板采用螺栓连接是冷弯薄壁型钢桁架杆件之间的第二种连接方式，桁架上每个节点板的形状及螺栓孔的布置可根据节点周围杆件的内力而定，一般均不相同，这给桁架的制作和加工带来很***烦，并且螺栓孔的开孔面积太大，截面削弱的太多，所以应用不多；通过金属板和自攻螺丝相连解决桁架节点问题是冷弯薄壁型钢杆件之间的第三种连接方式，但目前的节点板一般设计为平板，无冲压压筋，无翻边，且不通用，并且为方便自攻螺丝的安装，节点板一般较薄，受压时容易发生局部失稳而降低了桁架节点的承载能力，另外，每个节点板上需预先打孔，以便于自攻螺丝的就位，这无形中又增加了节点制作的工作量，使施工不方便。2. The connection mode of the closed square-shaped cold-formed thin-walled steel truss composite beam members is welded, bolted or self-tapping screws. Welding is the first direct connection between cold-formed thin-walled steel truss members. Although this type of connection has large bearing capacity and does not require a contact plate, the welding work is large, labor-intensive, and due to the steel truss member cross-section Thinner, the welding operation is very inconvenient, the welding quality is difficult to guarantee; the bolting connection through the gusset plate is the second connection between the cold-formed thin-walled steel truss members, the shape of each gusset plate on the truss and the bolt hole The arrangement can be determined according to the internal force of the rod around the node, which is generally different, which causes great trouble for the manufacture and processing of the truss, and the opening area of the bolt hole is too large, and the section is weakened too much, so the application is not much Solving the truss node problem by connecting the metal plate and the self-tapping screw is the third connection method between the cold-formed thin-walled steel members, but the current gusset plate is generally designed as a flat plate, without stamping ribs, without flanges, and Not universal, and in order to facilitate the installation of self-tapping screws, the gusset plate is generally thin, and local instability is likely to occur when pressure is applied, which reduces the load carrying capacity of the truss nodes. In addition, each node plate Pre-perforated to facilitate self-tapping screws in place, which virtually has increased the workload of nodes produced, so that the construction is inconvenient.

3、墙体片柱是钢结构中常用的钢柱结构形式，其与基础的连接通常的做法是在柱底面设置底板，柱两侧面设置靴梁，如果承载力不够，还可以在靴梁之间增加隔板，在靴梁外设置肋板，此柱脚形式与基础连接不牢固，同时存在结构复杂、加工安装不便、无法进行集约化生产、施工精度不高的缺点，此外，施工现场需要对构件进行切割和焊接，对现场施工人员的技术要求较高，现场热施工工作量大，同时容易在施工现场发生火灾存在安全隐患。3, the wall column is a steel column structure commonly used in steel structure, the connection with the foundation is usually set on the bottom of the column floor, the two sides of the column set the shoe beam, if the bearing capacity is not enough, it can also be in the shoe beam The partition plate is added, and the rib plate is arranged outside the shoe beam. The structure of the column foot is not firmly connected with the foundation, and the structure is complicated, the processing and installation are inconvenient, the intensive production cannot be performed, and the construction precision is not high. In addition, the construction site needs Cutting and welding the components, the technical requirements of the on-site construction personnel are high, the on-site thermal construction work is large, and it is easy to have a safety hazard in the fire at the construction site.

The problem of stress requirements; it is also necessary to solve the problem that the floor beam, the connecting pipe and the floor panel are prone to chattering and deformation; it is also necessary to solve the technical problem that the gusset plate is easy to be damaged first, the component integrity is poor, and the construction process is complicated; It is also necessary to solve the technical problem that the existing wall column and the foundation are not firmly connected, the form of the column for connecting with the foundation is complicated, the intensive production cannot be performed, the production efficiency is low, and the site safety accident is easily caused.

有益效果Beneficial effect

与现有技术相比本发明具有以下特点和有益效果：本发明创造出一种全新的楼面梁与轻钢结构上下层连接的特殊连接件和连接方法，使轻钢结构的楼面梁与上下层连接更加方便、牢固、安全，解决了楼面梁无法直接与上下层墙体承重桁架同时连接的问题，还解决了楼面梁局部承压不易满足受力要求的缺点。所述楼面梁可以通过穿梁扣件与上下层承重墙体桁架形成直接连接（即楼面梁的上弦杆穿过穿梁扣件、将楼面梁与上下层墙体承重桁架用自攻螺丝紧密牢固连接在一起，使楼面梁与上下层墙体承重桁架形成连续连接）。Compared with the prior art, the invention has the following characteristics and beneficial effects: the invention creates a new special connecting piece and connecting method for connecting the upper and lower beams of the floor beam with the upper and lower layers of the light steel structure, so that the floor beam of the light steel structure is The connection between the upper and lower layers is more convenient, firm and safe, and solves the problem that the floor beams cannot be directly connected with the load-bearing trusses of the upper and lower walls, and also solves the shortcoming that the partial pressure of the floor beams is not easy to meet the requirements of the force. The floor beam can be directly connected with the upper and lower load-bearing wall trusses by means of a beam-fastening member (ie, the upper chord of the floor beam passes through the through-beam fastener, and the floor beam and the upper and lower wall load-bearing truss are self-tapping) The screws are tightly and firmly connected to form a continuous connection between the floor beam and the upper and lower wall load-bearing trusses).

所述穿梁扣件增强了轻钢龙骨房屋体系的结构稳定性，其不但可以使楼面梁与上下层墙体承重桁架紧固连接，使楼面梁的局部承压完全满足受力要求，而且可以使楼面梁、连接管和楼面板不再发生轻易颤动，使楼面装饰层也不再会被轻易破坏，同时住在轻钢龙骨房屋体系中的人也不再会产生不安全感。The thread-piercing fastener enhances the structural stability of the light steel keel house system, which not only enables the floor beam to be fastened to the upper and lower wall load-bearing trusses, so that the partial pressure of the floor beam completely satisfies the stress requirement. Moreover, the floor beams, connecting pipes and floor slabs can no longer easily vibrate, so that the floor decoration layer will no longer be easily damaged, and the people living in the light steel keel house system will no longer feel insecure.

所述穿梁扣件将楼面梁的上弦杆通过自攻螺丝紧密牢固连接在上下层墙体承重桁架上，增大了楼面梁的上弦杆与下层墙体承重桁架连接处的剪切受力面积，克服了传统轻钢龙骨体系楼面梁不能对准下层墙体承重桁架、以及楼面梁容易局部被压屈变形的缺点。同时，使用了穿梁扣件后，楼面梁不再是任意放置在连接墙体桁架的连接管上了，所以也就不再具有楼面梁直接承受上层荷载而导致楼面板扰度大的缺点。The threaded fastener fastens the upper chord of the floor beam tightly and firmly to the upper and lower wall load-bearing trusses by self-tapping screws, thereby increasing the shearing of the joint between the upper chord of the floor beam and the lower wall of the load-bearing truss The force area overcomes the shortcomings of the traditional light steel keel system floor beam that cannot be aligned with the underlying wall load truss and the floor beam is easily deformed locally. At the same time, after the beam fastener is used, the floor beam is no longer placed on the connecting pipe connecting the wall truss, so there is no longer any problem that the floor beam directly bears the upper layer load and the floor panel is highly disturbed. Disadvantages.

此外，传统的结构在楼面梁上安装楼面板后，上下层连接件的连接上层孔位会被挡住，这就导致上下层连接件无法连接上层墙体承重桁架，从而降低了上下层的连接强度、稳定性及施工的安全性问题。而本发明所述的穿梁扣件的长度比传统的上下层连接件长，所以上下层连接件的上端高出楼面板20mm～100mm，因此在楼面梁上安装楼面板后，穿梁扣件还可以方便的与上层墙体承重桁架连接，克服了上下层墙体承重桁架之间连接强度差、稳定性差及施工安全性差的缺点。In addition, after the traditional structure is installed on the floor beam, the upper and lower joints of the upper and lower joints are blocked, which results in the upper and lower joints not being connected to the upper wall load truss, thereby reducing the connection of the upper and lower layers. Strength, stability and safety of construction. However, the length of the through-beam fastener according to the present invention is longer than that of the conventional upper and lower layer connecting members, so the upper end of the upper and lower layer connecting members is 20 mm to 100 mm higher than the floor panel, so after installing the floor panel on the floor beam, the beam buckle is worn. The piece can also be conveniently connected with the upper wall load-bearing truss, which overcomes the shortcomings of poor connection strength, poor stability and poor construction safety between the upper and lower wall load-bearing trusses.

本发明所述的45°梁柱组合扣件可广泛应用于轻钢结构梁或柱的组合，其一次冲压成型，制造精度高，施工过程可实现流水施工，节约施工成本。The 45° beam-column combined fasteners of the invention can be widely applied to the combination of light steel structural beams or columns, and the one-step stamping molding has high manufacturing precision, and the construction process can realize the flow water construction and save the construction cost.

And rigidity; open the screw hole on the connecting plate, which is convenient for self-tapping screw connection.

本发明所述45°梁柱组合扣件通过自攻螺丝与主体杆件连接，克服了传统连接方式制作工作量大、承载力和刚度低、质量难以保证的缺点，其形状和连接孔洞通过模具一次冲压成型，制作和安装都非常方便，可广泛用于冷弯薄壁金属桁架杆件之间的连接。The 45° beam-column combined fastener of the invention is connected with the main body rod by a self-tapping screw, which overcomes the shortcomings of the traditional connection method, such as large workload, low bearing capacity and rigidity, and difficult quality assurance, and the shape and the connection hole pass through the mold. One press forming, easy to manufacture and install, can be widely used for the connection between cold-formed thin-walled metal truss members.

本发明所述45°梁柱组合扣件，将相邻腹杆间的夹角设定为特定的45°并在上弦杆和下弦杆之间连续设置，实验证明，此结构形式受力性能明显优于已有的各种连接形式，组合梁承载力得到了极大的提高。The 45° beam-column combination fastener of the invention sets the angle between adjacent webs to a specific 45° and is continuously arranged between the upper chord and the lower chord. Experiments prove that the structural form has obvious force performance. Compared with the existing various connection forms, the bearing capacity of the composite beam has been greatly improved.

本发明所述的基础连接件可广泛应用于轻钢结构中墙体与基础连接，其通过冲压形成一个带双翼的中心槽一体扣件，并将其对称设置在轻钢片柱两侧，其底板通过螺栓与基础连接，此连接方式大大提高了墙体与基础连接的牢固度，使轻钢房屋更加稳固安全。The basic connecting member of the invention can be widely applied to the wall and the foundation connection in the light steel structure, and forms a central groove integral fastener with two wings by punching, and symmetrically disposed on both sides of the light steel sheet column, The bottom plate is connected to the foundation by bolts. This connection method greatly improves the firmness of the connection between the wall and the foundation, and makes the light steel house more stable and safe.

本发明通过预制基础连接件，可实现集约式工厂生产，避免了现场二次施工，节约了施工时间，加快了施工进度。The invention can realize intensive factory production through prefabricated basic connecting parts, avoiding secondary construction on site, saving construction time and speeding up construction progress.

本发明的基础连接件一体成型，可实现准确定位，与格构柱和连接底梁之间通过螺栓直接连接，有效的加快了施工速度，提高了生产效率。The basic connecting member of the invention is integrally formed, can realize accurate positioning, and is directly connected with the lattice column and the connecting bottom beam by bolts, thereby effectively speeding up the construction speed and improving the production efficiency.

本发明通过在面和面相接的棱上冲压加强压痕，可增强基础连接件的抗剪，确保了基础连接件的强度，同时可加强对柱底部剪力的抵抗。The invention strengthens the indentation by punching and punching on the edge of the surface and the surface, thereby enhancing the shear resistance of the basic connecting member, ensuring the strength of the basic connecting member and strengthening the resistance to the shearing force at the bottom of the column.
