Abstract
The utility model relates to a concrete die propping stick belonging to a construction tool for controlling the thickness of the concrete wall. The die propping stick takes a cuboid shape, grooves for clamping horizontal reinforced bars for the wall body are respectively formed at both ends of the cuboid which is a thickness away from a protective layer at the end part of the cuboid, and the width and the height of the grooves are both 2 mm more than the diameter of the horizontal reinforced bars for the wall body. The processing size is accurate, and the sectional dimension of the wall body and the thickness of the protective layer can be well controlled; two rows of the concrete die propping sticks are vertically placed when in use without binding, the operation is easy, the demands of construction can be met, and the construction progress is quickened; and the concrete die propping stick can be used for replacing the reinforced bar die propping stick, save the packing pieces, also solve the problem of return of rust of the reinforced bar die propping stick.
Description
Technical field:
The utility model relates to a kind of construction instrument of controlling the concrete wall body thickness, the specifically a kind of concrete backform rod that can effectively control thickness of wall body, thickness of concrete cover.
Background technology:
In the reinforced concrete wall construction, reinforcing bar backform rods such as the two F cards of main at present use are used to control thickness of wall body, cooperate cushion block control protective layer thickness.There is following defective in reinforcing bar backform rods such as two F cards:
1, cooperate the cushion block construction to need to repeat colligation with reinforcing bar backform rods such as two F cards, complicated operation, efficiency is low, and chain of command is incomplete, cushion block often occurs to walk, and protective layer thickness is not enough, even phenomenons such as reinforcing bar exposes occur.
2, reinforcing bar backform rod termination such as two F cards must be with the flat back of cutting machine saw brush rustproof paint, and processing and fabricating is slow.
3, reinforcing bar backform rod intensity such as two F cards is low, and arrangement pitch is close, waste material.
The utility model content:
The purpose of this utility model is the many defectives at prior art, and a kind of simple in structure, concrete backform rod of being convenient to operate, can effectively control thickness of wall body and protective layer thickness is provided.
Realize above-mentioned purpose by the following technical solutions: a kind of concrete backform rod; described backform rod is a cuboid; the protective layer thickness place, two end distance ends of this cuboid has respectively blocks the groove that the body of wall horizontal reinforcement is used, this recess width and highly all many 2mm than body of wall horizontal reinforcement diameter.
Preferred version of the present utility model is: the length of described cuboid is lacked 2mm than thickness of wall body, and wide is 25mm, and height is 35mm.
Adopt technique scheme, compared with prior art, the utility model processing dimension is accurate, but better controlled wall section size, protective layer thickness.Transfer two rows on the concrete backform rod during use, through calculating than reinforcing bar backform rod economy such as two F cards, economical with materials.Concrete backform rod is processing and fabricating by the gross, need not the colligation easy operating during construction operation, can satisfy the construction needs, accelerates the engineering construction progress.The utility model can substitute reinforcing bar backform rod and economize cushion block again, can also solve the problem that reinforcing bar backform rod returns rust.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
See Fig. 1; the utility model is a kind of concrete backform rod that substitutes reinforcing bar backform rod such as two F cards; the backform rod is length=wall thickness-2mm; wide=25mm; the cuboid 1 of height=35mm; protective layer thickness 3 places, two end distance ends of described cuboid 1 have respectively blocks the groove 2 that the body of wall horizontal reinforcement is used, the width of groove 2 and highly all many 2mm than the diameter of body of wall horizontal reinforcement.
The utility model utilizes useless composite board, the flitch fabrication of concrete backform rod mould of job site, and past mould is built the pea gravel concreten of higher-strength, after the maintenance moulding, reaches 28d intensity, and mold removal is finished product concrete backform rod.
When construction is used, to transfer two rows on the concrete backform rod, directly cross-arm is on the body of wall horizontal reinforcement, because the width of groove 2 and highly all many 2mm than the diameter of body of wall horizontal reinforcement, small surplus makes groove 2 firmly block body of wall horizontal reinforcement, simple operation.
Claims (2)
1. a concrete backform rod is characterized in that, described backform rod is a cuboid, and the protective layer thickness place, two end distance ends of this cuboid has respectively blocks the groove that the body of wall horizontal reinforcement is used, the width of this groove and highly all many 2mm than the body of wall horizontal reinforcement.
2. concrete backform rod according to claim 1 is characterized in that the length of described cuboid is lacked 2mm than thickness of wall body, and wide is 25mm, and height is 35mm.
