本发明涉及一种建筑用钢结构， 尤其涉及一种轻钢龙骨的连接结构。 背景技术  The invention relates to a steel structure for construction, in particular to a connection structure of a light steel keel. Background technique
随着建筑业的高速发展，新型建筑材料不断涌现，而作为新型建筑材料的轻钢龙骨由 于其具有重量轻、 强度高、 防水、 防火、 防震、 安装使用方便等诸多优异的性能越来越广 泛地地应用于各种建筑结构中，在使用轻钢龙骨构建结构的过程中，必然经常需要将不同 轻钢龙骨之间连接起来， 该连接一般采用的是焊接、 螺接或者铆接的方式。  With the rapid development of the construction industry, new building materials continue to emerge, and the light steel keel as a new building material is more and more widely used due to its light weight, high strength, waterproof, fireproof, shockproof, easy to install and use. The ground is used in various building structures. In the process of constructing the structure using the light steel keel, it is often necessary to connect different light steel keels. The connection is generally by welding, screwing or riveting.
结合当前轻钢应用的情况，上述轻钢龙骨连接时的连接结构需要满足一定的要求：① 强度要求， 如静强度、 疲劳强度等； ②尺寸要求， 如螺钉、 螺栓或者铆钉之间的中心距及 单个中心到任意边的距离要求； ③刚度要求， 如结构的刚性应足够强， 抵抗外部载荷时变 形应小到不至于引起附于其上的装修材料如石膏板开裂、破损； ④工艺要求， 该结构应容 易实现加工， 且过程简单、 操作可靠， 质量稳定； ⑤此外， 从结构设计角度而言， 采用这 种连接结构的设计在材料成本等方面应具有一定的优势，如能起到减轻材料重量、降低材 料成本的作用。  In combination with current light steel applications, the connection structure of the above-mentioned light steel keel needs to meet certain requirements: 1 strength requirements, such as static strength, fatigue strength, etc.; 2 dimensional requirements, such as the center distance between screws, bolts or rivets And the distance from a single center to any side; 3 stiffness requirements, such as the rigidity of the structure should be strong enough, the deformation should be small enough to resist the external load, such as gypsum board cracking and damage; The structure should be easy to process, and the process is simple, the operation is reliable, and the quality is stable. 5 In addition, from the perspective of structural design, the design using such a connection structure should have certain advantages in terms of material cost, etc. Reduce the weight of materials and reduce the cost of materials.
采用焊接相连的方式， 虽然可以满足上述的强度、尺寸以及刚度方面的要求， 但该种 连接方式为不可拆卸的连接， 材料再生利用性差、操作较为复杂且对环境污染较大， 故而 较常见的还是采用螺接或铆接的活动相连方式。  The method of welding connection can meet the above requirements of strength, size and rigidity. However, the connection method is non-removable connection, the material has poor recyclability, complicated operation and large environmental pollution, so it is more common. It is also connected by means of screwing or riveting.
为了使得采用活动相连方式的轻钢龙骨的连接结构可满足上述的连接强度要求，通常 会考虑增大连接件的直径， 但是， 由于轻钢龙骨所用的钢材厚度较薄， 且连接结构还必须 满足上述的尺寸要求， 因此所用的螺钉、螺栓或者铆钉等连接件的直径无法做到很大， 故 而无法通过此方法使得连接结构达到很高的强度要求。  In order to make the connection structure of the light steel keel adopting the movable connection method to meet the above connection strength requirements, it is generally considered to increase the diameter of the connecting member, but the thickness of the steel used for the light steel keel is thin, and the connection structure must also satisfy The above dimensional requirements, therefore, the diameter of the connecting members such as screws, bolts or rivets cannot be made large, so that the connecting structure cannot achieve high strength requirements by this method.
并且，现有的采用活动连接方式的轻钢龙骨连接结构也无法达到很好的刚度要求，具 体说明如下：如图 1中所示是一个典型的轻钢墙体结构，其中左侧的图形为正常未受力情 况下的轻钢墙体结构，右侧的图形为受力变形之后的轻钢墙体结构，从图 1中可以看出在 采用现有连接结构的情况下，虽然结构中也有加强刚性的斜拉结构，但结构在面内沿对角 方向还是会变形， 这一点在装配结构时会很明显， 即： 在左侧的图形中如将 B点固定约 束， 在 D点施加横向推力， 则可从右侧的图形中可以看出此时结构的变形非常明显， 以 一个 2800 (高） X 3800mm (宽） 的轻钢墙体为例， 当在 D点施加 40KG载荷时， 对角线 AC和 BD长度差将达到 60mm (没有变形时对角线差为 0)， 这种变形容易导致结构本身 及附着在轻钢上的装修材料如石膏板等的破坏。  Moreover, the existing light steel keel connection structure using the movable connection method can not achieve a very good rigidity requirement, and the specific description is as follows: as shown in Fig. 1, a typical light steel wall structure, wherein the left side figure is The light steel wall structure under normal unstressed condition, the figure on the right side is the light steel wall structure after the force deformation. It can be seen from Figure 1 that in the case of using the existing connection structure, although there is also Strengthen the rigid cable-stayed structure, but the structure will be deformed in the diagonal direction in the plane. This is obvious when assembling the structure, that is: in the figure on the left side, if the point B is fixed, the horizontal point is applied at point D. For the thrust, it can be seen from the graph on the right that the deformation of the structure is very obvious. Take a 2800 (high) X 3800mm (wide) light steel wall as an example. When applying a 40KG load at point D, The difference between the length of the corner AC and BD will reach 60 mm (the diagonal difference is 0 when there is no deformation), and this deformation easily causes damage to the structure itself and the decoration materials such as gypsum board attached to the light steel.
还有， 由于现有的轻钢龙骨连接结构无法达到很高的强度以及刚度要求， 因而该连接 结构在使用时，通常必需通过增加轻钢组合件上的轻钢龙骨的排布密度来保证组合件的稳 定性，这样一来也就无法很好地满足上述连接结构需满足的减轻材料重量、降低材料成本 的要求。 发明内容 Also, since the existing light steel keel connection structure cannot achieve high strength and rigidity requirements, the connection is When the structure is used, it is usually necessary to ensure the stability of the assembly by increasing the arrangement density of the light steel keels on the light steel assembly, so that the weight of the material to be satisfied by the above connection structure cannot be satisfactorily satisfied. Reduce material cost requirements. Summary of the invention

本发明的轻钢龙骨连接结构在连接处设置有凹窝结构，该凹窝结构非常容易实现机械 化的大批量生产； 又由于上下连接面的凹窝结构互相叠套， 故而装配时极易定位； 再加上 该凹窝结构内又可同时容纳两个以上的连接件，故而轻钢龙骨的连接强度以及刚性也得到 了大大的提高， 因为一个连接点采用两个以上的连接件连接， 载荷将由各连接件分担， 所 以连接强度得到了提高，又因为该两个以上的连接件的约束，被连接的轻钢龙骨在连接点 再也难以发生相对转动， 所以大大提高了结构的刚性； 并且， 由于该轻钢龙骨连接结构可 以达到很高的强度以及刚度要求，因而可以适当减小使用该连接结构的轻钢组合件上的轻 钢龙骨的排布密度，从已得到的设计实例分析数据来看，采用该种连接结构节省材料的使 用量可达到 15 %以上， 故而减轻了材料的重量、 降低了材料的成本； 还有， 由于凹窝结 构具有一定的深度，故而连接件的顶端平面可完全没入所述凹窝内， 因此不会对轻钢龙骨 表面上的其他连接部件造成干涉。 The light steel keel connecting structure of the invention is provided with a dimple structure at the joint, the dimple structure is very easy to realize mechanized mass production; and since the dimple structures of the upper and lower joint faces are mutually stacked, the assembly is extremely easy to position; In addition, the dimple structure can accommodate more than two connecting members at the same time, so the connection strength and rigidity of the light steel keel are greatly improved, because one connecting point is connected by more than two connecting members, and the load will be Sharing of joints, The connection strength is improved, and because of the constraint of the two or more connectors, the connected light steel keel is no longer relatively rotatable at the connection point, thereby greatly improving the rigidity of the structure; and, due to the light steel keel The connection structure can achieve high strength and rigidity requirements, so that the arrangement density of the light steel keel on the light steel assembly using the connection structure can be appropriately reduced. From the analysis data of the obtained design examples, the species is adopted. The connection structure saves the material usage by more than 15%, thereby reducing the weight of the material and reducing the cost of the material; further, since the dimple structure has a certain depth, the top end plane of the connecting member can completely fall into the concave It does not interfere with other connecting parts on the surface of the light steel keel.
然而， 以上所述仅为本发明的较佳可行实施例， 并非限制本发明的保护范围， 故凡运 用本发明说明书及附图内容所作出的等效结构变化， 均包含在本发明的保护范围内。  However, the above description is only a preferred embodiment of the present invention, and does not limit the scope of the present invention.
