Abstract
The utility model discloses a positioning ring for a reinforced concrete protective layer, which is formed by carrying out extrusion molding on high polymer material ethylene-propylene rubber. The outermost layer of the positioning ring is a circular outer ring (1). Sector holes (2), reinforcing ribs (3), a steel bar through hole (4), positioning latches (5), a reversed clamp (6) and a reversed clamp groove (7) are arranged in the outer ring (1). The sector holes (2) are positioned between the outer ring (1) and the steel bar through hole (4). The reinforcing ribs (3) are positioned between the two sector holes (2) and between the sector holes (2) and the reversed clamp groove (7). The positioning latches (5) are positioned around both ends of the steel bar through hole (4) and extend slantingly upwards at an angle of 60 degrees. The utility model overcomes the defects that in the conventional method, when a mortar cushion block is manually manufactured, the mortar cushion block has nonuniform thickness and large deviation and is difficult to place firmly; and when a steel wire is adopted to bind, the protective layer is easy to generate deviation and time and labor are wasted. The utility model provides the positioning ring for the reinforced concrete protective layer, which is accurate to position, has high strength, is convenient to construct and is convenient and rapid to operate.
Description
Technical field
This practicality relates to a kind of centring ring, particularly a kind of reinforced concrete protective layer centring ring.
Background technology
During construction work reinforced concrete protective layer cast at present, its topping reinforcing bar all adopts the mortar cushion block, or adopt granite fine grained chippings, stone, fragment of brick etc. as the reinforcement cover locating support, and at the location of reinforcement cover corner, because mortar cushion block, granite fine grained chippings, stone, fragment of brick equal strength are not enough, crushed easily, and its out-of-shape, be difficult for being placed firm, easily cause phenomenons such as protective layer thickness deficiency, reinforcing cage off normal, dew muscle, stay serious hidden danger to engineering; Adopt the iron wire colligation traditionally, solved the difficult problem of reinforcement cover corner location to a certain extent, but not firm, the easy off normal of topping, time-consuming has had a strong impact on the quality and the construction engineering quality of steel concrete.
The utility model content
Utility model provides a kind of reinforced concrete protective layer centring ring; purpose is to solve at tendon protective layer corner; traditional mortar cushion block, granite fine grained chippings, stone, fragment of brick equal strength are not enough; easily crushed; be difficult for being placed firm and during the iron wire colligation, not firm, the easy off normal of topping, time-consuming technical barrier.
The utility model is that the technical scheme that its technical barrier of solution is adopted is: a kind of reinforced concrete protective layer centring ring, adopt the poly-third ethene extrusion modling of macromolecular material, its outermost layer is circular outer ring, is provided with scallop hole, reinforcing rib, reinforcing bar through hole, location latch, the draw-in groove that falls to block and fall in the outer ring; Described scallop hole is between outer ring and reinforcing bar through hole, and described reinforcing rib is between the scallop hole and scallop hole and falling between the draw-in groove; Described location latch is positioned at around the reinforcing bar through hole two ends, and is 60 ° of angles and stretches obliquely.
Described scallop hole, its quantity are 3.
Described reinforcing rib, its quantity are 4.
Described location latch is arranged on around the reinforcing bar through hole two ends equably, and all leaves the gap between each latch.
Described card, its quantity is 2, is arranged on down in the draw-in groove.
Described reinforced concrete protective layer centring ring adopts the poly-third ethene extrusion molding of macromolecular material.
The beneficial effects of the utility model: accurate positioning, firm; overcome manual manufacture mortar cushion block became uneven; deviation is excessive; be difficult for being placed firm; and during the iron wire colligation; the easy off normal of topping, time-consuming technical barrier provide the topping keeper of intensity height, easy construction, simple operation to construction works.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
In the accompanying drawing: 1. outer ring, 2. scallop hole, 3. reinforcing rib, 4. reinforcing bar through hole, 5. location latch 6. falls card, 7. falls draw-in groove.
The specific embodiment
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
As shown in drawings, a kind of reinforced concrete protective layer centring ring, adopt the poly-third ethene extrusion modling of macromolecular material, its outermost layer is circular outer ring 1, is provided with scallop hole 2, reinforcing rib 3, reinforcing bar through hole 4, location latch 5 in outer ring 1, blocks 6 and fall draw-in groove 7; Described scallop hole 2 is between outer ring 1 and reinforcing bar through hole 4, and described reinforcing rib 3 is between the scallop hole 2 and scallop hole 2 and falling between the draw-in groove 7; Described location latch 5 is positioned at around reinforcing bar through hole 4 two ends, and is 60 ° of angles and stretches obliquely; Described scallop hole 2, its quantity are 3; Described reinforcing rib 3, its quantity are 4; Described location latch 5 is arranged on around reinforcing bar through hole 4 two ends equably, and all leaves the gap between each latch; Describedly block 6, its quantity is 2, is arranged on down in the draw-in groove 7.
