Background technology
Detect code according to " JGJ106-2003 " architecture foundation pile inspection specifications, " DCJ32/TJ42-2012 " building lot base, when detecting the vertical anti-pulling capacity of single pile, test pile is connected with testing arrangement and generally adopts the mode of welding.The method is that on the main reinforcement that stretches out with reinforcing bar one welding test pile head end, one is welded on the girder on testing arrangement.The method major defect is: because construction plant environment is poor, and need on the main reinforcement that every root reinforcing bar one welding test pile head end stretched out with electric welding machine, one is welded on the girder on testing arrangement, more time-consumingly to take a lot of work, efficiency is not high.Also need with cutting equipment, the reinforcing bar connected to be cut off after finishing test, the girder on testing arrangement is due to multiple welding and cutting, and application life reduces, and cost of production increases simultaneously at every turn.
And at present single pile vertical resistance to plucking static loading test generally adopts the mode of welding to be: with electric welding machine, every root reinforcing bar one is welded on the main reinforcement that test pile head end stretches out, one is welded on the girder on testing arrangement, the method is more time-consuming, take a lot of work, efficiency is not high.Also need with cutting equipment, connecting reinforcement to be cut off after finishing test, the girder on testing arrangement is due to multiple welding and cutting, and application life reduces, and cost of production increases simultaneously at every turn.
Summary of the invention
The object of the invention is the problem solving above-mentioned proposition, a kind of a kind of single pile vertical pullout tests Special connecting device without the need to adopting welding and cutting equipment accurately can record single pile vertical CAPO test is provided.
The object of the invention is to realize as follows: a kind of single pile vertical pullout tests Special connecting device, there is the test pile being arranged on and splitting stake hole, described test pile end face has main reinforcement, lower loaded plate is inserted on described main reinforcement, described lower loaded plate is connected with upper loaded plate by Level tune pulling force connecting rod, be positioned at bottom described upper loaded plate and be connected with hydraulic jack, described upper and lower two loaded plates be arranged in parallel.
Above-mentioned a kind of single pile vertical pullout tests Special connecting device, is connected with jack ball pivot between described upper loaded plate and hydraulic jack.
Above-mentioned a kind of single pile vertical pullout tests Special connecting device, described Level tune pulling force connecting rod is through fastening by adjusting nut after described upper loaded plate.
Above-mentioned a kind of single pile vertical pullout tests Special connecting device, described hydraulic jack is fixed on the reaction beam of horizontally set.
Above-mentioned a kind of single pile vertical pullout tests Special connecting device, described lower loaded plate is provided with intermediate plate ground tackle, and described intermediate plate ground tackle is set on the main muscle of stake.
Above-mentioned a kind of single pile vertical pullout tests Special connecting device, described intermediate plate ground tackle is parallel with lower loaded plate end face.
Above-mentioned a kind of single pile vertical pullout tests Special connecting device, described reaction beam is fixed on ground line by bearing pile.
Advantage of the present invention: stake vertical resistance to plucking static loading test Special connecting device of the present invention, be adopt a kind of novel method of attachment, the components such as this linkage adopts upper and lower loaded plate, reinforcing bar intermediate plate ground tackle, Level tune pulling force connecting rod form.This device is enclosed within the main reinforcement that test pile head end stretches out with lower loaded plate, and the main reinforcement stretched out with reinforcing bar intermediate plate ground tackle locking test pile head, replaces the girder on testing arrangement with loaded plate, use Level tune connecting rod, connect upper and lower loaded plate.Do not need electric welding machine and reinforcing bar cutting equipment, only need connect test pile and testing arrangement with connecting rod, simple to operation, efficiency is higher.This linkage can Reusability simultaneously, cost-saving obvious.Mainly solve the problem that above test pile and testing arrangement connected mode produce.
