Abstract
The utility model relates to a steel tube supporting movable end and belongs to the technical field of foundation pit support protects, which is mainly used on the occasion that the foundation pit support utilizes steel structure inner supporting. The steel tube supporting movable end can be quickly applied in a construction site, has reliable quality, and can be produced in batches. The steel tube supporting movable end can be technically characterized by comprising a rabbet and a movable end sleeve. The rabbet utilizes two corbels so that the supporting point can bear force more evenly and reliably. A jack platform is arranged in the middle of the two corbels, thereby being capable of aiming at the supporting center when the jack adds force. The sleeve is divided into chambers by welded steel plates so that the rabbet is convenient to insert into the chambers to fix. A notch is reserved between the corbels and is convenient for a wedge block to be arranged. The end portion of the sleeve is a flange plate which can be connected with a supporting steel tube.
Description
Technical field:
The utility model belongs to the foundation pit supporting project technical field, is mainly used in pattern foundation pit supporting structure and adopts situation about supporting in the steel work.
Background technology:
Interior support supporting belongs to a kind of of Base hole supporting technology, can be divided into steel concrete support or shaped steel support according to material.When excavation of foundation pit during designated depth, for guaranteeing foundation ditch safety, supports supporting to design the setting in foundation ditch, foundation pit side-wall is provided prop up the follow-up continuous excavation of overfill protection reliably.Support has the characteristics of quick construction in the shaped steel, has through specialized designs to apply the pre-applied force function, so that more effectively control foundation pit deformation.The most extensive in supporting in the shaped steel with support applications in the steel pipe.Steel pipe supports and to be divided into movable termination and fixing termination, and an end that applies pre-applied force with the support of jack pair steel pipe is commonly referred to movable termination.The movable end technology is the key of support technology in the shaped steel, and it is lack of standardization to exist movable end to make at present, inconvenience is installed, and there is the situation of potential safety hazard in the piecemeal activity termination.
Summary of the invention:
It is quick that the utility model is to provide a kind of job site to use, reliable in quality, the novel product that can make in batches.
This product has following technical characterictic: be made up of tenon and movable end sleeve part.Tenon adopts two brackets to make fulcrum stressed more even reliable, for laying the jack platform, can aim at the centre of support when jack is afterburning in the middle of two brackets.Be separated into the chamber by welding steel in the sleeve, be convenient to tenon and insert indoor fixing.Bracket is reserved notch and is convenient to install wedge.Sleeve ends is a flange, can be connected with supporting steel pipe.
Description of drawings:
The utility model is seen accompanying drawing 1～accompanying drawing 2, constitutes tenon by [1-1]～[1-5], and [2-1]～[2-7] constitutes sleeve, and [3] are wedge.
Accompanying drawing 1 steel pipe support activity termination ()
Accompanying drawing 2 support activity terminations (two)
The specific embodiment:
Support activity termination is prefabricated in the factory, select corresponding specification as required for use, hoisted in position is supported with steel pipe in the scene, after the tenon of movable termination inserts sleeve, lay jack in the middle of the tenon bracket and apply pre-applied force, the purlin that encloses on movable termination and the foundation pit side-wall is held out against, after pre-applied force applies and finishes, insert bracket with wedge and reserve the notch fixed support, remove jack, can in the middle of bracket, add voussoir in case of necessity.
Claims (4)
1. a support activity termination comprises tenon and movable end sleeve, it is characterized in that: tenon is by tenon base plate, tenon bracket, tenon bracket stiffening rib, and the tenon backing plate constitutes, the movable end sleeve is by steel pipe, vertical stiffener, laterally stiffener, prop up the top backing plate, flange, the flange stiffening rib constitutes.
2. according to the described tenon of claim 1, it is characterized in that described 2 tenon brackets are symmetrical arranged, tenon bracket front end is established the reservation notch of open top bottom lock, and tenon backing plate planar dimension can be placed jack, height is set can makes jack aim at movable end sleeve center.
3. movable end sleeve according to claim 1 is characterized in that described movable end sleeve is separated into the chamber by vertical and horizontal stiffener, chamber bulk and tenon bracket size match, and the active segment sleeve ends is established flange and is connected with support.
