Abstract
The present invention belongs to the technical field of a building component. The present invention relates to a steel bar positioning plastic support frame for a shear wall. The support frame has two functions for leading steel bars to be positioned and a protective layer to be arranged. The present invention is made of engineering plastic. Two groups of steel bar positioning members on the left and the right are connected by a buckle. A bayonet with elasticity is arranged on a wheeled type structure of the steel bar positioning member. An elasticity clamping slice is arranged in the bayonet. The outer surface of a straight rod part is provided with a groove. The outer side of a wheel rim of the wheeled type structure of the steel bar positioning member is provided with three convex points. When the present invention is used, after two rows of steel bars of a shear wall are bound, a plastic frame with a proper length is adopted to be perpendicular to the two rows of steel bars, and the bayonet is clamped on the steel bar at the outer side. Compared with the prior art, the present invention has the advantages of high strength, good elasticity, accurate size, fixation, high firmness, etc. The present invention can not be exposed. The present invention is a steel bar positioning support frame which is indispensable to concrete building engineering.
Description
Technical field
The invention belongs to the building unit technical field, specifically is a kind of shear force wall reinforcing steel bar location plastic stent that is used for.
Background technology
In the prior art, shear wall structure is a highrise building concrete structure pattern commonly used, and shear force wall reinforcing steel bar is double reinforcing bar.In construction in the past, S shaped steel muscle commonly used is controlled double bar space as tension rib, protects thickness of protection tier with sand oar cushion block.Because tension rib can only be controlled not outwards skew of bi-steel, and can not control it to bias internal.Add the easy fragmentation of sand oar cushion block and come off, so the position of shear force wall reinforcing steel bar and protective layer thickness are difficult to be guaranteed.In addition, Chinese patent also discloses the reinforcing bar fixed support that a kind of patent No. is ZL91206901, and this frame is limit owing to structure, the bayonet socket place does not have elasticity, can not hold the reinforcing bar of multiple diameter, and the length of adding between two bearings is non-adjustable, caused model too much, drawback such as difficulty of processing is big.
Summary of the invention
The invention solves the technical problem that shear force wall reinforcing steel bar location and shear wall protective layer thickness meet design requirement, provide a kind of reinforcing bar location and topping shear force wall reinforcing steel bar that two functions are set is one that collects to locate plastic stent.
The present invention realizes like this, shear force wall reinforcing steel bar location plastic stent, include the reinforcing bar align member, the straight bar part that it is characterized in that two reinforcing bar align members is that screw thread connects, the wheeled construction of reinforcing bar align member is provided with elastic bayonet socket, can hold the reinforcing bar of φ 10-16 in the elastic bayonet lock of this wheeled construction; Be provided with an elastic card in the bayonet socket, with guarantee reinforcing bar by closely connected on the endoporus outer wall.
The external surface of the straight bar part of reinforcing bar align member of the present invention is provided with groove, to strengthen and concrete bonding.
The wheel rim outside of the wheeled construction of reinforcing bar align member of the present invention is provided with salient point, and the distance between this bump surface and the endoporus outer wall is the shear force wall reinforcing steel bar protective layer thickness, and this salient point is set, and makes support be the some contact with contacting of template.
The used plastics of the present invention are engineering plastics.
The straight bar part of reinforcing bar align member of the present invention is connected with extension bar, one end of extension bar is provided with screw mandrel, the other end is provided with a hole, bar length can be arranged to different length, the extended type plastic stent that links to each other and can form different length with the straight bar part of reinforcing bar align member is with the installation needs of the shear force wall reinforcing steel bar that adapts to different-thickness.
The present invention compared with prior art has the following advantages and effect, reasonable in design adopts engineering plastics to make, and has intensity height, good springiness, size standard, fixed and characteristics such as do not expose, and can regulate length, be suitable for the needs of different-thickness body of wall; It is one that this support collection reinforcing bar location and topping are provided with two functions, the double reinforcing bar of shear wall is connected is connected into integral body, can guarantee that double bar space of shear wall and thickness of protection tier meet design requirement.Therefore, improving shear force wall reinforcing steel bar installation quality and shear wall concrete structure engineering entity quality greatly, is indispensable reinforcing bar locating support in a kind of concrete construction engineering.

The specific embodiment
With reference to the accompanying drawings embodiment is further described, shear force wall reinforcing steel bar location plastic stent adopts engineering plastics to make, about the straight bar part of two groups of reinforcing bar align members 2 be that screw thread connects, extension bar 4 can be made into the different length of 50mm, 100mm, the length of this support is decided according to the thickness of shear wall, the wheeled construction of reinforcing bar align member 2 is provided with elastic bayonet socket, is provided with an elastic card 3 in the bayonet socket, and the external surface of straight bar part is provided with groove.The wheel rim outside of the wheeled construction of reinforcing bar align member 2 is provided with three salient points 1.During use the double reinforcing bar binding of shear wall well after, select the plastics frame of appropriate length for use, perpendicular to double reinforcing bar, bayonet socket is stuck on the reinforcing bar of the outside gets final product wiring colligation again.The spacing of installing is generally one row about 1m, and among every row about level interval 1m one, the S type tension rib of installation position is promptly substituted by plastic stent.
