Description
Technical field
The invention belongs to build applications in civil engineering technical field, it is related to a kind of prestressing force composite reinforcing hardened system.
Background technology
Prestressing force composite reinforcing is common reinforcing material in a kind of civil engineering, is mainly used in concrete construction
Plate and the studying for a second time courses one has flunked of beam, reinforcement；The opening reinforcement of wall and plate periphery；Wood makes the reinforcement of beam of building etc.；Bridge plate, bridge pier,
The reinforcement of purlin；Tunnel, the studying for a second time courses one has flunked of cable pipeline, reinforcement.
Prestressing force composite reinforcing answers material lightweight, and single pretension is small, and anchorage is light and simple, is set without large-scale construction
Standby, difficulty of construction is small, and speed of application is fast, and quality control is easy；In addition, the durability of composite reinforcing material is far superior to steel, later stage
Maintenance costs is very low.
Composite reinforcing is fixed and tensioning needs reinforcement device, so that composite reinforcing is in tension, to reach prestressing force
The application effect of drawing.Existing bracing means is to clamp at the both ends of composite reinforcing by anchorage, and one of anchorage is fixed, another
A anchorage can be moved by outer force effect, generally drive another anchorage to tense composite reinforcing by jack.But due to compound
Muscle diameter itself is little, and grasp is inadequate between anchorage, is easy to be detached from anchorage under higher pulling force during the installation process, or
Person upon installation as time goes by, the gradual phase middle shrinkage of composite reinforcing and both ends are detached with anchorage.
Invention content
The purpose of the present invention is there is the above problem in view of the prior art, it is proposed that a kind of prestressing force composite reinforcing reinforcing system
System, composite reinforcing are connected firmly with anchorage.
Object of the invention can be realized by the following technical scheme：A kind of prestressing force composite reinforcing hardened system, including it is solid
Determine anchorage, mobile anchorage, tensioning seat, end plate, tensioning threaded rod, jack, fixed anchorage and tensioning seat are fixed by anchor bolt
It is being reinforced body surface, the both ends of composite reinforcing are separately fixed on fixed anchorage and mobile anchorage, and tensioning seat is located at mobile anchor
Among tool and end plate, jack is resisted against between tensioning seat and end plate, and the both ends of tensioning threaded rod are equipped with locking nut, special
Sign is that composite reinforcing both ends are connected with taper sheath, and taper sheath front end is provided with cross recess, and composite reinforcing is viscous by glue with taper sheath
It connects, fixed anchorage includes being provided with the fixation anchor slab of anchor hole and being locked at the fixation clip on fixed anchor slab by bolt, fixed
Anchor slab and fixation clip are provided with the half round platform slot one for accommodating taper sheath, two and half round platform slots, one face and clamp taper sheath,
The mobile pressing plate that mobile anchorage includes mobile anchor slab and is locked at by bolt on mobile anchor slab, mobile anchor slab and mobile pressing plate
It is provided with the half round platform slot two for accommodating taper sheath, two and half round platform slots, two face and clamps taper sheath, mobile anchor slab both sides are opened
Have for tensioning threaded rod horizontal through circular hole one, tensioning seat is square plate, and several anchor holes, tensioning seat two are provided on tensioning seat
Side be provided with for tensioning threaded rod horizontal through circular hole two, be provided on end plate for tensioning threaded rod horizontal through circular hole three.
Before installation, taper sheath is sticked to the both ends of composite reinforcing, composite reinforcing both ends can be caught in taper sheath, pass through taper sheath
It is fixed with fixed anchorage or mobile anchorage, fixed anchorage and mobile anchorage are all dismountable, are put into half round platform slot compound
After muscle, anchor slab and pressing plate are locked by bolt.After tightening force of the mobile anchorage by jack, taper sheath is in half round platform slot
Middle sliding, since half round platform slot of anchorage is gradually smaller, until can not readvance, to make anchorage clamp taper
Set, taper sheath are pressurized and tighten port, keep the connection of taper sheath and composite reinforcing more secured.This clamping structure of anchorage not only may be used
With in-site installation, be readily transported entire hardened system, can separate and transport to construction site and assembled again, and composite reinforcing by
Stretching force is bigger, and taper sheath clamps more secured.
Further, the taper of the taper sheath is identical as the taper of half round platform slot one and half round platform slot two.Work as taper sheath
When sliding into most the inside along half round platform slot one or half round platform slot two, since taper is identical, taper sheath outer surface is contacted with cell wall
Face is maximum, then stiction and grasp between the two is also the largest, taper sheath is enable to be secured firmly in anchorage.
Further, respectively there is the rectangular ear outwardly protruded, circular hole two to be opened on rectangular ear for tensioning seat both sides.Make
Two tensioning threaded rod keeping parallelism states, anchorage held stationary when by the pulling force of tensioning screw rod mobile in this way move.
Further, the anchor hole number on the fixed anchor slab is 4-10.4-10 anchor hole, improves fixed anchor slab and is added
Gu the firmness of body surface.
Further, the anchor hole number on the tensioning seat is 4-10.4-10 anchor hole improves tensioning seat and is reinforced object
The firmness in body surface face.
Further, the tensioning threaded rod between tensioning seat and end plate be equipped with locking nut, the locking nut with
Pulling seat leans.When composite reinforcing reaches preset prestressing force, rotation lock nut makes locking nut lean with tensioning seat,
Ensure that tensioning threaded rod and mobile anchorage position are fixed, then can lay down jack.
Compared with prior art, this prestressing force composite reinforcing hardened system has the following advantages：
1. it is all dismountable to fix anchorage and mobile anchorage, the scene of capable of transporting is installed with composite reinforcing and taper sheath again,
It is readily transported；
2. fixing anchor there is half round platform slot one, mobile anchorage to have half round platform slot two, when mobile anchorage pulls back composite reinforcing
When, since taper sheath is pasted at the both ends of composite reinforcing, composite reinforcing stress pull taper sheath toward half round platform slot one or half round platform slot two compared with
Small mouth movement, and cross recess is provided on taper sheath, taper sheath squeezes and shrinks its portlet, makes taper sheath clamping composite reinforcing more
Tightly, so not readily disengaging from anchorage, and stress is bigger under external force, and the clamping force that anchorage closes muscle is bigger, and fixation is got over
Securely.
