发明内容Contents of the invention
为提供一种节点构造简单、整体性能良好、生产和施工的难度低、环境友好经济合理的建筑结构构件，本发明公开了一种加强的预制再生混凝土梁柱节点及施工方法。采用钢和再生混凝土材料制成，具有施工便捷、性能优良、成本低廉的特点。In order to provide a building structural member with simple joint structure, good overall performance, low production and construction difficulty, environmental friendliness, economy and reasonableness, the invention discloses a reinforced prefabricated recycled concrete beam-column joint and a construction method. Made of steel and recycled concrete materials, it has the characteristics of convenient construction, excellent performance and low cost.
为了实现上述要求，本发明采取如下的技术解决方案：一种加强的预制再生混凝土梁柱节点，由预制混凝土梁构件、预制混凝土柱构件、纵筋、箍筋、角钢和螺栓连接件组成。其特征在于：加强的预制再生混凝土梁柱节点由四块角钢或两块角钢或两块钢板构成，同时作为浇筑预制再生混凝土梁柱节点的模板，两相邻角钢或钢板的间距为梁宽减去两侧保护层厚度，通过螺栓连接件连接；并在相邻角钢所夹空间中沿柱长方向和梁长方向铺设纵筋并用箍筋绑扎，延伸一定长度；相互垂直设置的纵筋之间形成钢筋笼，作为基本骨架；浇入再生混凝土后形成一种加强的预制再生混凝土梁柱节点。In order to achieve the above requirements, the present invention adopts the following technical solution: a reinforced prefabricated recycled concrete beam-column joint, which is composed of prefabricated concrete beam components, prefabricated concrete column components, longitudinal bars, stirrups, angle steel and bolt connectors. It is characterized in that: the reinforced prefabricated recycled concrete beam-column joint is composed of four angle steels or two angle steels or two steel plates, and is used as a template for pouring prefabricated recycled concrete beam-column joints at the same time, and the distance between two adjacent angle steels or steel plates is beam width minus Remove the thickness of the protective layer on both sides and connect them through bolted connectors; lay longitudinal reinforcement along the column length direction and beam length direction in the space between adjacent angle steels and tie them with stirrups to extend a certain length; between vertical reinforcements A reinforced cage is formed as the basic skeleton; a reinforced prefabricated recycled concrete beam-column joint is formed after pouring recycled concrete.
节点沿预制梁和预制柱方向外伸长度根据实际施工要求控制在80cm以内。The extension length of nodes along the direction of prefabricated beams and prefabricated columns is controlled within 80cm according to actual construction requirements.
角钢由钢板焊接而成，通过螺栓连接件连接。角钢代替传统工艺有效地改善了相邻两肢折角处的应力集中现象明显的情况，增大了梁的抗剪能力。The angle steel is welded by steel plates and connected by bolted joints. The use of angle steel instead of the traditional process effectively improves the obvious stress concentration phenomenon at the knuckles of adjacent two limbs, and increases the shear resistance of the beam.
节点端部设置一个高25cm的正方体凸起，预制混凝土柱构件和预制混凝土梁构件端部开一个内深30cm的正方体凹槽。凸起和凹槽的尺寸由梁柱实际尺寸确定，凸起的尺寸边长不小于15cm，同时凹槽的尺寸边长不得大于30cm，以防止连接处有足够的强度。在预制混凝土梁构件和预制混凝土柱构件的端部预留钢筋孔洞，作为节点中外伸纵筋插入孔。并在预制混凝土梁构件和预制混凝土柱构件的侧面预留钢筋灌浆。施工时通过灌浆孔压力灌入水泥基灌浆料填实后，停止灌浆，静养1—2天。凹槽和凸起的设置和预留孔插筋灌浆的方法可以使梁柱和节点之间对接稳固。A cube protrusion with a height of 25cm is set at the end of the node, and a cube groove with an inner depth of 30cm is opened at the end of the precast concrete column member and the precast concrete beam member. The size of the protrusions and grooves is determined by the actual size of the beams and columns. The side length of the protrusions should not be less than 15cm, and the side length of the grooves should not be greater than 30cm, so as to prevent the connection from having sufficient strength. Rebar holes are reserved at the ends of the precast concrete beam members and precast concrete column members, and are used as the insertion holes for the outstretched longitudinal reinforcement in the nodes. And reserve reinforcement grouting on the sides of precast concrete beam components and precast concrete column components. During construction, the cement-based grouting material is poured into the grouting hole for filling, then the grouting is stopped and rested for 1-2 days. The arrangement of grooves and protrusions and the method of grouting through reserved holes can make the connection between beams and columns and nodes stable.
采用建筑垃圾再生骨料混凝土作为主要建筑材料，从而达到环境友好、绿色环保的目的。Recycled aggregate concrete from construction waste is used as the main building material, so as to achieve the purpose of environmental friendliness and green environmental protection.

4.在水平方向，安装预制混凝土梁构件1。将该种加强的预制再生混凝土梁柱节点设置的凸起4和梁端设置的凹槽11互相对接。并将预制再生混凝土梁柱节点端部延伸出的纵筋2插入预制梁上的预留钢筋孔洞9，通过灌浆孔灌入水泥基灌浆料填实。养护硬化。4. Install the precast concrete beam member 1 in the horizontal direction. The protrusions 4 provided at the joints of the reinforced prefabricated recycled concrete beams and columns and the grooves 11 provided at the ends of the beams are butted with each other. The longitudinal reinforcement 2 extended from the end of the prefabricated recycled concrete beam-column joint is inserted into the reserved steel bar hole 9 on the prefabricated beam, and cement-based grouting material is poured into the grouting hole for filling. Curing and hardening.
具体实施中，在加强的预制再生混凝土梁柱节点中设置的角钢可以外伸处一定的长度，便于将预制混凝土梁构件夹在两块钢板之间，有益于进一步加强节点与梁之间的整体性。In the specific implementation, the angle steel set in the reinforced prefabricated recycled concrete beam-column joints can be extended to a certain length, which is convenient for sandwiching the prefabricated concrete beam members between two steel plates, which is beneficial to further strengthen the overall connection between the joints and the beams sex.
