The utility model discloses a horizontal joint of a prefabricated sandwich insulation external wall, which relates to the field of construction technology. The purpose of the utility model is to solve the problem that the joint of the prefabricated sandwich insulation external wall panel is filled with cement grouting material, and the filling of the grouting material can not be completely compact, and water leakage is easy to occur. The main points of the technical scheme are as follows: the upper prefabricated sandwich wall panels, the lower prefabricated sandwich wall panels and the horizontal joints between the upper prefabricated sandwich wall panels and the lower prefabricated sandwich wall panels; the upper prefabricated sandwich wall panels include the inner leaf wall, the thermal insulation board and the outer leaf wall; the bottom of the outer leaf wall of the upper prefabricated sandwich wall panels is provided with a strip groove along the length direction of the outer leaf wall; and the inner strip groove is provided with an expansion strip. A strip groove 2 is arranged on the top surface of the outer leaf wall of the lower prefabricated sandwich wall panel along the length direction of the outer leaf wall, and a water absorption expansion strip 2 is arranged in the strip groove 2. The utility model blockades the leakage gap by a water absorption expansion strip and a water absorption expansion strip, so as to improve the waterproof performance of the horizontal joint.

一种预制夹心保温外墙水平接缝
本技术涉及建筑
,更具体地说,它涉及一种预制夹心保温外墙水平接缝。
技术介绍
预制夹心保温外墙板(又称三明治墙板)是集承重、围护、保温、防水、防火等功能为一体的重要装配式预制构件。生产夹心保温外墙板时,内叶墙、保温层及外叶墙一次成型,通过连接件连接形成一体,无需再做外墙保温,施工难度降低。参照图1,现有的预制夹心保温外墙包括上预制夹心墙板1、下预制夹心墙板2以及上预制夹心墙板1与下预制夹心墙板2之间的水平接缝21,上预制夹心墙板1包括内叶墙11、保温板12和外叶墙13。在施工现场对预制夹心墙板进行装配式拼装时,在竖直方向相互拼装的外叶墙13之间会形成水平接缝21,施工工人会在水平接缝21处用灌浆料或抹灰填充。但是,上述水平接缝21处的灌浆料或抹灰填充无法完全密实,当外叶墙13面临暴雨时,雨水容易沿着水平接缝21向内渗透,易产生漏水,因此有待进一步改进。
技术实现思路
针对现有技术存在的不足,本技术的目的在于提供一种预制夹心保温外墙水平接缝,其具有防水性能好的优势。为实现上述目的,本技术提供了如下技术方案:一种预制夹心保温外墙水平接缝,包括上预制夹心墙板、下预制夹心墙板以及上预制夹心墙板与下预制夹心墙板之间的水平接缝,所述上预制夹心墙板和下预制夹心墙板均包括内叶墙、保温板和外叶墙,所述上预制夹心墙板的外叶墙底面上沿外叶墙长度方向设置有条形槽一,所述条形槽一内设置有吸水膨胀条一,所述吸水膨胀条一的截面呈半圆形;所述下预制夹心墙板的外叶墙顶面上沿外叶墙长度方向设置有条形槽二,所述条形槽二内设置有吸水膨胀条二,所述吸水膨胀条二的截面呈半 ...
