Foreword
This standard is equivalent to using ISO 7844. 1985 "between the reinforced concrete slabs with connecting bars and concrete watered Grooved vertical access
Inner mechanics laboratory test plane slit influence to load "(in English).
This standard of ISO 7844. 1985 made the following editorial changes.
--- "This International Standard" by "this standard";
--- Remove ISO 7844. 1985 foreword, preface to increase the national standard.
The standard proposed by the Ministry of Housing and Urban-Rural Development of the People's Republic of China.
This standard is under the jurisdiction of the Ministry of Construction of housing building products Standardization Technical Committee, components and products with the urban and rural areas.

0 Introduction
Study on the big board structure shows that the vertical joints between the wall member occupies an important position in the structure.
Under the joint performance fully grasp the situation, analyze the impact of these seams using modern computing methods. Therefore, the purpose of this standard
It is to provide a test method for determining the performance of the major joints.
This standard does not involve the analysis and use of test results. Since it is often difficult for such a large number of tests, so the standard does not specify a minimum test
The number of inspection, it should pay attention to the dispersion, because it often affects the results of such tests, these tests will therefore be desirable to repeat
The number, it will better represent the actual situation.
To support the design of large wall panels calculations, taking into account the mechanical properties of reinforced concrete slabs between the vertical joints, the mechanical properties can be
By cutting a large in-plane board joints between the load and the relative displacement relationship to represent.
1 Overview
Laboratory mechanical tests of this standard provides a method for determining certain types of vertical joints between concrete slabs in tangential bearing
When load, load and tangential relative displacement relationship.
2 range
This standard can be used for vertical joints meets the following conditions between large panels.
Geometry a) edge of the board so that the concrete poured into the seam to transmit force to become a wedge bond;
b) connecting two wall panels should be reinforced through the high and evenly distributed throughout the plate, while small steel vertical spacing required;
c) strength of concrete pouring large plate should be at least equal to the strength of concrete poured into the seams.
This standard applies to the load by the tangential impact (along the seam shear) situation.
3 Test principle
The edges of two slats connected together to form a seam specimen, applying tangential load, recorded in different tangential load variable value of specimen
Shape and damage (cracks and damage) situation.
4 test device
Test equipment should meet the following criteria.
--- To ensure that the plates side is rigidly fixed;
--- Allow axial sliding along a seam;
--- Avoid equipment damage to the specimen before deformation;
--- Ensure urging axial direction along the seam.
