Overview

 

1.1.

 

Brief Introduction to the Device

 

PCE-HT  224E  Digital  Rebound  Apparatus  is  a  product  designed  according  to 

Technical 

Regulations  for  Concrete  Compressive  Strength  Test  by  Rebound  Method

  (JGJ/T23-2001) 

(hereinafter  referred  to  as 

Regulations

)  and  developed  in  order  to  meet  actual 

requirements  for  the  field  test  of  concrete  compressive  strength,  applicable to  the  non-
destructive testing of common concrete compressive strength in all kinds of construction 
engineering.  It  is  specifically  applicable  to  the  on-site  quality  sampling  inspection  by 
Engineering  Quality  Supervision  Institutions  and  Supervising  Units,  for  the  compressive 
strength test result of the inspected concrete structure can be got immediately; when the 
Construction Quality Testing Institution carries out on-site test for real construction objects, 
it can further reflect the fairness, scientificity and accuracy of the test, greatly improving 
the working efficiency of testing, data processing and inspection report formation.

 

PCE-HT 224E Digital Rebound Apparatus has the following characteristics: integrated design, 
small in size; adopt non-contact optical  coupler sense to realize data collection, without 
changing the original physical structure of mechanical rebound apparatus, in which way the 
optical  coupler  sensor  has  no  contact  nor  friction  with  the  mechanical  part  of  rebound 
apparatus and thus its service life is extended; inside of the apparatus, national curve and 
local curve are provided, can be set optionally by yourself; angle, tested surface, pumping 
or not, carbonization depth and other parameters can be set on site; after detecting data 
of original value, the original rebound value, testing zone strength value, component overall 
strength value and other data of the completed component can be checked immediately; 
self-contained access control further reflects the fairness and safety of the test; equipped 
with USB data transmission interface, able to transfer data to computer; computer software 
saves  the  test  data  as  Excel  format,  and  reporting  format  can  be  created  immediately, 
simple and convenient for the later software process; memory space of original data are as 
much as 1000 components.

 

1.2.

 

Structure of Concrete Test Hammer

 

The Concrete Test Hammer is mainly composed of flip system, value-indicating system and 
shell component

Its structure is shown in Fig

1

  The diagram shows the state that the 

impact  hammer  has  finished  impact  in  the  test  and  the  pushbutton  has  locked  the 
movement

ie

retaining state of resilience value
