Abstract
The utility model relates to an embedded rib material strengthening concrete beam tool, which can be used for an embedded prestressed and unprestressed rib material strengthened building or structure. The tool can effectively solve the problem that an embedding method can not be applied in building structure strengthening project reality, i.e. a prestressing problem and a glue infusing problem. A system self-balancing system is designed in solving the prestressing problem, and after prestressing is succeeded, a main girder of the strengthening tool can be firstly disassembled so as to reduce the difficulty of separating the rib material and the strengthening tool. The girder is tightly stuck to a beam to be strengthened to convert flue infusing problem in a groove into a glue infusing problem in a hole, and inverted groove glue infusing is possible. The strengthening tool can be widely applied for strengthening various types of buildings.
Description
Technical field
Patent of the present invention relates to a kind of embedded muscle material and reinforces instrument.
Background technology
Current, Building Trade in China has entered newly-built and maintenance and renovation is laid equal stress on, and will build the new period that emphasis turns to existing building transformation, maintenance, reinforcing aspect, the past substandard building of building changes the new demand of bringing can not satisfying present economic development and use after use after a while, need keep in repair it, reinforcing and modernization restructuring.The transformation of existing building structure is reinforced in building trade in the future and will be occupied an leading position.Research on Reinforcement Method at concrete member in the building is varied at present, and embedded reinforcing method (Near-surface Mounted is called for short NSM) is more representational a kind of novel reinforced method.This worker's method flow process is as follows: at first slot on concrete cover, then cementing agents such as epoxy resin are injected groove, with in FRP material (muscle or the lath) embedded groove, make it to become integral body again, co-operation reaches good consolidation effect.Compare with outer subsides method, embedded reinforcing method also has following some advantage except having advantage such as high-strength, efficient, corrosion-resistant equally: the Surface Machining working strength is low, shock resistance, durability and fireproof performance is good, anchored force is strong.Abroad relatively early to embedded reinforcing technique experimental study, 1996, Lulea Polytechnics has carried out the embedded reinforcement test of FRP square-section first, De Lorenzis (2000), Hassan and Rizkalla (calendar year 2001) have carried out the test of CFRP muscle embedded reinforcement subsequently, have carried out a series of similar tests afterwards.Compare western countries, China is later relatively for the research of embedded reinforcing method, 2004, the Yue Qingrui professor of State Industrial Building Diagnostic and Reform Engineering Technology Research etc. introduces the achievement of external embedded fibre reinforced plastics reinforced concrete member first to domestic, systematically introduce embedded type reinforcing method engineering abroad and used and the scientific research situation, comprised the use material, advantage, construction technology of embedded type reinforcing method etc.; Meanwhile, the Li Rong of The Hong Kong Polytechnic University, rise scholars such as bright and beautiful light the embedded reinforcement method has also been carried out detailed summary, external test is comprised that adhesive property test, anti-bend reinforced test, failure mode etc. have carried out commentary.This immediately new reinforcement means has caused extensive concern at home.Though embedded muscle material reinforcing method has above-mentioned various advantages, only be in the theoretical research aspect in the civilian construction reinforcing at present, can't put into practical engineering application.Its main cause be the building reinforce beam specific volume is little mutually with bridge, do not have corresponding job practices.The i.e. research and development of relevant construction technology also are in blank.In theory research, scientific research personnel's method that the muscle material is embedded is very simple, at first builds the beam of a collection of same specification, beam is inverted in the middle of two special pedestals then.Along the parallel fluting of long axis direction, with the fixing muscle material in reinforcing bar two ends, the muscle material is embedded in the beam groove then in its bottom, and at beam two ends usefulness colloid sealing groove mouth, injecting glue condenses at last.Then need on pedestal, to operate for prestressed applying.Yet in engineering reality, we reinforce to as if building itself rather than single beam, we can not peel off out from building integral with it.No matter so be the anchoring (especially applying prestressing force) of muscle material or injecting glue all can't be realized easily in groove.Based on from last argumentation, we have researched and developed a kind of practical embedded muscle material hardened system, make embedded reinforcement means can be applied to quickly and easily during construction work reinforces.
Summary of the invention
This system mainly is made up of roof beam structure, lever, detachable rotating shaft and afterburner system.Afterburner system adopts the punching jack to be advisable, and no longer draws in system construction figure.(top is embedded rinforcement bar material for roof beam structure, lever and muscle material, the bottom is flexible materials such as steel strand) form self equilibrium systems at perpendicular, the termination that embedded rinforcement bar material two ends are provided with is stuck in lever upper end indentation, there, tightens up lever lower end steel strand by afterburner system and applies prestressing force.During reinforcing roof beam structure is held up, its upper surface is close to treating the reinforcement soffit, and the muscle material is in appropriate depth in the groove.At notch both sides pressurization injecting glue, make evenly closely knit being full of in the groove of colloid.Removing the reinforcing instrument after the colloid generation active strength gets final product.

The specific embodiment
When using this instrument to reinforce the building girder member, at first use cutting machine at the beam nip, notch is square is advisable, and suitably strengthen the notch cross section at its two ends, then with the muscle material 1 of two ends anchoring (for helix rib steel wire, recommend to use the screw anchoring) hang over lever 2 tops, the lever bottom is applied certain prestressing force with afterburner system (punching jack etc.), the instrument of beam type reinforcing at this moment forms a prestressing force self equilibrium systems., it is close to treats at the bottom of the reinforcement the hardened system bed hedgehopping with crane.The muscle material just in time embedded and waited to reinforce in the fine strain of millet groove this moment, sealed and reserve gum-injecting port at the notch two ends with mortar (or other coagulating agent).The girder steel upper surface is stained with plastic sheeting, and the muscle material is placed on the film, at notch two ends pressurization injecting glue.After treating that colloid curing is condensed, remove lever bottom afterburner system, the lever shaft 3 of dismantling, reduce crane, girder steel is withdrawn from, carefully remove notch sealing part mortar, pull down lever (use chemical gelling agent to do under the situation that notch seals processing, the method that available heat sources heats removes lever) on lever.Reinforce the groove two ends at beam then and mend glue, so far strengthening member finishes.
