Description
Technical field
The invention belongs to the civil structure field, be specifically related to be used for the steel plate water booster system and the pressure method of works steel-bonded reinforcement.
Background technology
Existing works need regularly carry out the inspection and maintenance maintenance in the interim damage that all can occur in various degree of operation, need carry out reinforcement and strengthening in case of necessity.Affixing steel plate reinforcement is a kind of application works maintenance and reinforcement method the most widely, all can adopt the steel bonding method to carry out reinforcement and strengthening for works bending resistance or the not enough position of shearing resistance, and effect is remarkable.The affixing steel plate reinforcement general flow is location → boring → clear hole → steel plate eliminate rust → smear adhesive → plant bolt → curing, protection → check.
The stickup of steel-bonded reinforcement worker method light plate is crucial.Method in common is on the works basal plane after surface of steel plate and the cleaning, to smear adhesive; Simultaneously open anchor hole at surface of steel plate and works basal plane; After hanging on the lead screw to the hole steel plate hole then; The nut that screws up with a wrench carries out the anchoring extrusion forming to steel plate, makes steel plate closely connected on concrete surface.
This steel plate is pasted pressuring method and is applicable to beam slab top or the local small size affixing steel plate of works usually.For large-area beam slab bottom or side steel-bonded reinforcement, only there is very big limitation through the bolt pressurization, also be infeasible in the practice of construction.Striding footpath T beam elongated affixing steel plate reinforcement at the bottom of beam with 20m is example, both can be with having divided block plate to paste at the bottom of the beam and integrally welded again after the nut pressurization, also can be earlier with dividing block plate to be welded as a whole again through smearing at the bottom of the pressurization of adhesive and bolt pastes beam.A kind of method needs overhead welding before the employing, and difficulty is bigger, and adhesive is flammable, and welding can cause the adhesive burning and the forfeiture effect again after piecemeal at the bottom of the beam is pasted; Adopting a kind of method in back to need to weld good elongated steel plate is lifted at the bottom of the beam; Steel plate weight is big, and is flexible big, needs very big manpower and machinery; And a limited number of bolts can't be born the steel plate effect of estimating one's own ability before adhesive solidifies; Also just can't realize pressurization, usually cause the steel plate obscission, the forfeiture consolidation effect steel plate.Therefore, research and develop a kind of effectively, be suitable for and the steel plate water booster system being convenient to construct has important practical significance and promotional value remarkable in economical benefits to development affixing steel plate reinforcement worker's method and works maintenance and reinforcement.
. summary of the invention
The present invention is directed in the present affixing steel plate reinforcement process; But the shortcoming that is pressed in the existence of application property aspect is pasted, added to steel plate; From simplified construction; Convenient construction, the quickening progress is saved steel plate water booster system and pressure method that aspects such as material, manpower and plant equipment have proposed a kind of U-shaped suspended structure thing steel-bonded reinforcement.
A technical scheme that realizes the object of the invention is:
The steel plate water booster system is made up of several U-shaped suspension arrangements, and each U-shaped suspension arrangement is made up of steel plate at the bottom of two blocks of side steel plates and, and steel plate is welded into the U type at the bottom of two blocks of side steel plates and one, on side steel plate and end steel plate, is provided with bolt hole.
U-shaped suspension arrangement structural form is following:
Adopt three bar steel plates to be welded into U-shaped, equal prepared screw-bolt hole on base and side steel plate.End steel plate length is not less than the width of pasting the position, and the side steel plate length should satisfy welding and smear the working space of adhesive.
As further improvement of the present invention; Said plurality of U-shaped suspension arrangement is along the length direction of beam, be installed at the bottom of the beam equally spacedly; Leave the space between the concrete surface at the bottom of steel plate of the said end and the beam; Said two blocks of side steel plates are located at the both sides of beam bottom respectively, are fixedly connected with the beam bottom through the bolt at bolt hole.
Steel plate water booster system among the present invention has simple structure, and it is convenient to construct, the characteristics that applicability is wide.Have stronger validity and economy.
Another technical scheme that realizes the object of the invention is:
The steel plate pressure method comprises the following steps:
Step 1) along the length direction of beam, be installed at the bottom of the beam equally spacedly, leaves space between end steel plate and the soffit with the plurality of U-shaped suspension arrangement, and two blocks of side steel plates are located at the both sides of beam bottom respectively, through bottom the bolt of bolt hole and beam, being fixedly connected;
Step 2) some affixing steel plates are positioned on the end steel plate of U-shaped device, affixing steel plate is provided with prepared screw-bolt hole, is welded as a whole after each affixing steel plate assembly unit;
Step 3) is smeared adhesive at concrete surface and affixing steel plate upper surface, affixing steel plate integral body is raised to beam at the bottom of, tighten on the affixing steel plate nut of anchor bolt in the prepared screw-bolt hole, affixing steel plate and concrete surface are fitted;
The nut of tightening in prepared screw-bolt hole bolt of step 4) on steel plate at the bottom of the U-shaped suspension arrangement makes bolt compress affixing steel plate, accomplishes the stickup and the pressurization of affixing steel plate;
Step 5) treats that adhesive solidifies the back and removes the U-shaped suspension arrangement.
Beneficial effect of the present invention is:
(1) welding is easier: compare with traditional affixing steel plate reinforcement; After adopting this device; Can after dividing block plate to be assembled on the U-shaped suspension arrangement, weld, steel plate is connected as one, avoid the flammable characteristics of overhead welding or adhesive; Simplify construction, be easy to guarantee the effect of welding quality and steel plate reinforcement;
(2) steel plate paste more convenient: big block plate welds and smears adhesive on U-shaped suspension arrangement at the bottom of the beam, only can be raised to beam then through manual work at the bottom of, reduced the lifting distance greatly.Manpower and plant equipment have been saved;
(3) pressurization better effects if: only compare through the pressurization of steel plate self erection bolt with traditional affixing steel plate reinforcement; This U-shaped suspension arrangement has increased on the base bolt to the secondary pressurization of steel plate; Therefore the better effects if of pressurizeing, the steel plate sticking effect is better, has effectively shortened adhesive hardening time.
(4) traffic vibration effect is little on the bridge: traditional steel plate strengthening with external bonding construction requirement is forbidden vehicle pass-through on the bridge in the adhesive curing time, and purpose is to reduce colloid to solidify the influence that receives.After adopting the U-shaped suspension arrangement, strengthened adhesive curing time effect, shortened the duration, can shift to an earlier date open to traffic the steel plate pressurization; And after the enhancing of pressurization effect, even there is traffic on the bridge, the influence of its vibration also reduces greatly.Therefore adopt affixing steel plate reinforcement behind the U-shaped suspension arrangement also to can be applicable to the bridge that can't suspend traffic.Make that steel plate strengthening with external bonding applicability is wider.
