Abstract
The invention discloses a method for testing a tall concrete formwork supporting system. The method includes the following steps of selecting a tall supporting formwork region layer of a project, determining a test region, building a mechanical calculation model of the formwork supporting system and analyzing and calculating data obtained through testing. According to the function mechanism that a cast-in-place concrete structure and a formwork support bear a time varying structure system in the construction stage is explored through on-site detection, a basis of the mechanical calculation model of the formwork supporting system is built, serves as a detection basis of laboratory structure tests and theoretical analysis results and provides a technical basis for mechanical analysis of the time varying system, control of safety of the formwork supporting system in the construction period and design and optimization of the construction scheme. Formwork supporting is achieved through on-site materials, the materials can be repeatedly used, concrete formwork supporting cost is reduced, project cost is reduced and the construction speed is improved.

Xoncrete structure high formwork support system (scaffolding height surpasses 8m) collapse accident constantly occurs in recent years, except ultimate bearing capacity deficiency is the large reason causing the accident, it is also one of the main reasons that xoncrete structure high formwork support system duty is understood to deficiency, so be extremely necessary to carry out field test test and theoretical analysis to guarantee the safety and reliability of falsework.
For the high formwork support system that China is generally used and accident rate is the highest, we are necessary to set up high and big die plate support on the spot, the relation of research load mode and support force, and multistory reinforced concrete floor and form bracing system are still lacked under the condition of further investigation, Site Detection obtains the firsthand information and seems particularly important to exploring and solve this engineering realistic problem.
Summary of the invention
The object of the embodiment of the present invention is to provide a kind of method of testing of concrete high formwork support system, is intended to solution and multistory reinforced concrete floor and form bracing system is still lacked to the problem of further investigation.
The embodiment of the present invention is achieved in that a kind of method of testing of concrete high formwork support system, and the method for testing of described concrete high formwork support system comprises the following steps:
Choose the high-supported formwork plate area level of engineering, determine test zone;
Set up form bracing system mechanics model;
Test is obtained to data, carry out analysis and calculation.
Further, the method for testing of described concrete high formwork support system adopts the method that on-the-spot entity test combines with theoretical analysis and calculation.
The method of testing of concrete high formwork support system of the present invention, by Site Detection, explore the mechanism of action that becomes structural system when construction stage cast-in-place concrete structure and shuttering supporting carry jointly, set up the basis of form bracing system mechanics model, it is the foundation of the test of check laboratory structure and theoretical analysis result, also can for time become structural system mechanical analysis, control the safety of construction time form bracing system, Construction Scheme and optimization provide technical basis, by existing material, carry out shuttering supporting, material can reuse, and then reduced concrete blinding and supported expense, reduced engineering cost, improved speed of application.
