Technical field
The present invention relates to a kind of prefabricated components inspection loading support, especially a kind of precast concrete stair structural behaviour inspection
Test loading support.
Background technology
Assembled architecture has that industrialized level is high, be easy to winter construction, reduce job site wet trade amount, reduce material
The advantages of consumption, reduction dust from construction sites and building waste, be conducive to improving construction quality and production efficiency, reduces cost, realization
Energy-saving and emission-reduction and the purpose of environmental protection.In recent years, with China's green construction, the raising of energy-saving and emission-reduction requirement, and work
The power market price is substantially improved, and precast concrete starts to be applied on a large scale in architectural engineering.Architectural stair
Traditional cast-in-situ construction method formwork is numerous and diverse, the amount of labour is big, efficiency is low, using precast stair can greatly improve production efficiency,
Reduce site operation intensity and save natural resources etc., therefore, over the past two years, precast stair starts in concrete multi-level and high level
Largely used in building.For construction enterprises, precast stair is similar with door and window, is used as a building subassembly.
However, precast stair is again different from door and window, safe escape passage when it is earthquake and fire, its importance is self-evident.Cause
This, specifies when using precast stair in construction standards, it is necessary to structure and property detection (i.e. loading examination is done in sampling by a certain percentage
Test).
Because precast stair two ends strong point absolute altitude is different, when load test is done, it is necessary to precast stair is placed on into one
On individual interim loading support.Load support specification need adapt to precast stair model, i.e., the precast stair two ends strong point it
Between the discrepancy in elevation and projected length.Usual way is to do the precast stair model of structure and property detection as needed, using channel-section steel or
The interim loading support of square steel tube Site Welding one.
In different engineerings or same engineering, may there is Multiple Type in the precast stair for being used, when to various types
Number precast stair sampling when doing structure and property detection, scene needs the interim loading support of the multiple specifications of welding, and this is resulted in
The waste of artificial and material.Therefore, in On-site Loading Test of Rc is carried out to precast stair, being capable of height and length to loading support
Degree is adjustable, it is adaptable to which the precast stair of different model proposes requirement.
The content of the invention
Technical assignment of the invention is directed to a kind of above-mentioned not enough precast concrete stair structure of offer of the prior art
Service check loads support, and precast concrete stair structure and property detection loading support has can be facilitated, continuous regulation
