Description
Technical field
The present invention relates to the assembly of new and old concrete joint in improvement project, more particularly to improvement project.
Background technology
Having concrete structure to transformation when built region carries out engineered must cut, but it is approximate with the buried depth of the newly-built concrete structure of transformation, specification, intensity to there is a situation where that part has concrete structure, if this part concrete structure of having had been friends in the past made full use of, spliced with newly-built concrete structure, substantial amounts of manpower and materials can be saved, it may also reduce building waste is produced and discharge.Common new and old concrete structure is assembled to be bonded using interfacial agents mostly, and this mode is not suitable for load-carrying members.
The content of the invention
It is contemplated that overcoming the defect of prior art, there is provided new and old concrete structures to form device and construction method in improvement project.The present invention is easy to operation；Substantial amounts of artificial and material cost is saved, while reducing the generation and discharge of building waste.
New and old concrete structures to form device in a kind of improvement project of the present invention, it includes one group of anchor, and each anchor includes anchor plate, clamping plate, floor, bolt, rubber water-proof plate, grouting valve and air bleeding valve；The groove of a longitudinally cutting insertion in the middle of old concrete structure, the rubber water-proof plate is attached in through slot；Anchor plate is fitted with old concrete structure cut surface, hydro-expansive rubber plate and bolt fit sealing；Fasten rear plate and clamp rubber water-proof plate both sides setting floor, make the seal cavity that closing is formed between old concrete structure and rubber water-proof plate；Grouting valve is located at bottom and connects grouting pump and Grouting Pipe, and air bleeding valve is located at top and is completely in open mode.
The construction method of new and old concrete structures to form device in a kind of improvement project described in basis, it includes：Install after the anchor, middle part grouting valve is first injected during slurry, both sides grouting valve is then injected, two grouting valves are symmetrically injected up and down, pressure balance is kept；Closed successively after the air bleeding valve discharge cement mortar of top, then proceeding to pressurize makes it keep 0.1MPa pressure, stops slip casting before treating cement mortar initial set, removes Grouting Pipe；Inject after cement mortar all solidifies and remove anchor plate bolt, the anchor plate, clamping plate, floor of anchoring clamping device are integrally extractd；Shank of bolt is implanted into old concrete structure by anchor bolt using bar planting mode, is used with new concrete structure welding as embedded bar.
The present invention anchors clamping device by old concrete structure and specification sectional making；Cut old concrete structure and rubber water-proof plate mounting groove；Anchoring clamping device, fastening bolt are installed；Grouting valve balance injection expansion cement slurry, keeps pressure to treat initial set up and down；Grouting Pipe is removed, expansion cement slurry removes anchoring clamping device after all solidifying；Welding structure reinforcing bar, new concrete structure unblock of constructing.The principle of the invention is simple, is easy to operation；Save substantial amounts of artificial and material cost；Reduce the generation and discharge of building waste.
Brief description of the drawings
Fig. 1 is the schematic diagram of the present invention.
Embodiment
As shown in Figure 1, new and old concrete structures to form device in a kind of improvement project of the present invention, it includes one group of anchor, the device is made up of anchor plate 1, clamping plate 2, floor 3, bolt 4, rubber water-proof plate 5, grouting valve 6, air bleeding valve 7, when cutting old concrete structure in the structure between a longitudinally cutting insertion groove, rubber water-proof plate 5 is attached in through slot；Anchor plate is fitted with the old cut surface of concrete structure 9, uses hydro-expansive rubber plate and bolt fit sealing；Fastening rear plate can clamp rubber water-proof plate, make the seal cavity that closing is formed between old concrete structure and rubber water-proof plate；Bottom grouting valve connection grouting pump and Grouting Pipe, top air bleeding valve are fully open；Middle part grouting valve is first injected during slip casting, both sides grouting valve is then injected, two grouting valves are symmetrically injected up and down, pressure balance is kept；Closed successively after the air bleeding valve discharge cement mortar of top, then proceeding to pressurize makes it keep 0.1MPa pressure, stops slip casting before treating cement mortar initial set, removes Grouting Pipe；Inject after cement mortar all solidifies and remove anchor plate bolt, clamping device will be anchored（Anchor plate, clamping plate, floor one）Excision；Shank of bolt can be implanted into old concrete structure by anchor bolt using bar planting mode, be used with new concrete structure welding as embedded bar.
