Description
Technical field
The present invention relates to a kind of reinforced bar sleeve and template connecting structure, belong to field of mechanical technique.
Background technology
Current grouting formula steel bar connecting structure mainly contains two profiles formula: full grouting formula steel bar connecting structure and half grouting formula steel bar connecting structure.What patent " nested grouting reinforced steel coupling sleeve " (patent No.: 200820090139.X) was stated is a kind of full grouting formula steel bar connecting structure, its sleeve lining total length is tapered thread, sleeve two ends are provided with elastic rubber sealing ring, the reinforcing bar that need connect inserts sleeve from sleeve two ends respectively, in whole sleeve, perfusion grouting material forms the connection syndeton of full bonding, and this full grouting formula steel bar connecting structure has following defect:
1. the length of sleeve is longer: grouting material is as power transmission medium, and for meeting the needs of adhesion strength, the length of sleeve is longer.
2. sealing and location difficulty: when embedded bar and sleeve, aperture, sleeve one end adopts elastic rubber sealing ring to seal reinforcing bar, and when preventing from pouring into a mould, concrete enters in sleeve.But practice of construction operating difficulties, flexible rubber seal is in sleeve aperture location difficulty, and forbidden because its elasticity had easily causes reinforcing bar and sleeve to be located, so sealing was easily lost efficacy, the component quality precast is poor, and excessive deviations can cause follow-up component assembly difficulty or cannot be assembled.
Patent " a kind of Novel cement grouting reinforcement connection syndeton " (patent No.: what 200920350787.9) state is a kind of half grouting formula steel bar connecting structure, this sleeve one end is provided with the internal thread hole of undergauge, be threaded with externally threaded reinforcing bar, the other end of sleeve adopts grouting material to carry out bonding connection.This by being threaded+method of bonding connection, effectively reduce length sleeve and the grouting material consumption reduced, and because one end (pre-buried end) is for being threaded, when Embedment Construction, reinforcing bar and sleeve seal with locate reliably, prefabricated quality easily ensures.But there is following defect in this half grouting formula sleeve:
1. bush material is rolled section steel, and manufacture mainly through machine, because being provided with the protruding ring rib (its cross section in echelon) and groove arranged continuously in hub internal bore, and the internal diameter size of regular size sleeve is less, this causes machining very difficult, working (machining) efficiency is low, and manufacturing cost is high, is difficult to the needs meeting batch production.
2. because the ring rib in endoporus and groove are formed by machining, process needs for convenience, designed protruding ring rib and the shape of groove do not take into full account the needs of adhesion stress.
3. because of the restriction of material and processing method, sleeve configuration is cylindrical or polygonal tubular, designs like this, processing difficulties cause the inconvenience of construction for the interface that need be connected with sleeve accessory (as grout pipe, outlet pipe) on sleeve.
Summary of the invention
The invention provides a kind of reinforced bar sleeve and template connecting structure, the sleeve of this syndeton is cast by high strength steel material and is formed, solve the problem that machine half grouting formula connects syndeton processing difficulties, solve simultaneously other by machine-tooled method affect in design with construct on defect.
For solving above technical problem, the invention provides following technical scheme: a kind of reinforced bar sleeve and template connecting structure, described syndeton comprises side template and Side Template, and side template is in both sides, and Side Template is connected to bottom two side templates; The connection of reinforced bar sleeve and side template is connected by outlet pipe and grout pipe, and the connection of reinforced bar sleeve and Side Template is bolted; Outlet pipe is arranged on above grout pipe.
Further, described reinforced bar sleeve comprises sleeve and Ribbed Bar, and described sleeve is cylinder, and cast by high strength steel material and form, the major part of sleeve is cylindrical cavity, and inner chamber is made up of the ring rib alternately arranged and groove; The aperture place of sleeve ends is a ring rib; Have two boss in cartridges sides, have two through holes and have internal thread through barrel bore wall in the middle part of boss, a boss is near sleeve end face aperture, and another boss is near inner chamber bottom surface; The sleeve other end is the profile that physical dimension is less is polygonal cylinder, and through hole and internal thread are established in this cylinder center, bottom the screwed hole of inner chamber bottom surface, be provided with shoulder; The wall thickness dimension located relative to other at the wall thickness near inner chamber bottom surface is larger.
Further, described Ribbed Bar end has external screw thread, is connected with the internal thread of sleeve; During two component assemblings, described Ribbed Bar inserts in barrel bore, and intubating length is slightly smaller than the axial dimension of barrel bore.
Further, described grouting material is a kind of strength cement-based grouting material, pours into or pour into from the grout pipe of cartridges sides from sleeve aperture.
Further, grout pipe is plastic straighttube, and end is provided with external screw thread and is connected with the side screw of sleeve.
This reinforced bar sleeve that the present invention relates to and template connecting structure, syndeton is simple, easy to connect.
