Abstract

一种预制空心板键式整体连接结构，将预制空心板板端之间的连接采用槽口对接、高压灌注混凝土形成混凝土键进行连接。本实用新型使预制空心板之间的连接成为整体结构，结构强度高，不容易出现接缝开裂，极大提高建筑质量,提高使用性能。

Description

预制空心板键式整体连接结构
技术领域：
本实用新型涉及建筑工程技术领域，具体涉及预制空心板键式整体连接结构。 
背景技术：
现有预制空心墙板与预制空心楼板的板端都为平整端面，预制空心墙板与预制空心墙板、预制空心楼板与预制空心楼板的连接依靠水泥砂浆和抗裂网络材料填补缝隙，因而其连接结构强度差，不能形成整体连接结构，特别是接缝极容易开裂，影响表观质量和使用性能。 
实用新型内容：
本实用新型所要解决的技术问题是：解决上述现有技术存在的问题，而提供一种预制空心板键式整体连接结构，使预制空心板之间的连接成为整体结构，结构强度高，不容易出现接缝开裂，极大提高建筑质量及使用性能。 
本实用新型采用的技术方案是：将预制空心板板端成型有外小内大的槽口，预制空心板之间的连接采用槽口对接、高压灌注混凝土形成混凝土键进行连接。 
上述技术方案中，所述的槽口采用圆形、多边形。 
上述技术方案中，预制空心板板边倒角填塞水泥砂浆。 
本实用新型将预制空心板板端成型有外小内大的槽口，安装连接时，采用现场高压灌注微膨胀细石混凝土，形成一个混凝土键，紧密连接两块板或紧密连接板与梁、柱，使之不能发生相互间的上下、左右双向位移，连接缝 在一般外力作用下不会发生开裂现象。同时，利用板边的倒角填塞水泥砂浆，加大了水泥砂浆与预制板的接触面，增大了砂浆与预制板的粘接力。 
附图说明：
图1为本实用新型实施例1结构剖面示意图； 
图2为本实用新型实施例2结构剖面示意图； 
图3为本实用新型实施例3结构剖面示意图； 
图4为本实用新型实施例4结构剖面示意图； 
图5为本实用新型实施例5结构剖面示意图； 
图6为本实用新型实施例6结构剖面示意图。 
图中，1——预制空心板，2——槽口，3——混凝土键。 
具体实施方式：
参见图1，将预制空心板板端成型有外小内大的槽口2，预制空心板1与预制空心板1的连接采用槽口2对接、高压灌注混凝土形成混凝土键3进行连接，所述的槽口2可采用圆形或多边形；同时，板边的倒角填塞水泥砂浆，加大水泥砂浆与预制板的接触面，增大砂浆与预制板的粘接力，使之结构强度高。
