Technical Field
The utility model relates to a construction field, in particular to nut formula concrete cushion.
Background
The concrete cushion block, also called reinforcing steel bar protective layer cushion block, is placed between the reinforcing steel bar and the template in the brick-concrete structure and frame structure, and can fix the position of the reinforcing steel bar to prevent the reinforcing steel bar from being exposed and corroded.
The concrete cushion block can effectively control the thickness of a protective layer of a concrete structure building, the thickness of the concrete protective layer of the reinforcing steel bar is related to the bearing capacity, durability, fire resistance and other performances of the structure, and when the protective layer is too thin, the anchoring force of the protective layer is reduced, so that the effect of the structure on resisting axial force and bending moment is reduced; when the protective layer is too thick, cracks are easily generated on the surface of concrete, and the stress of a steel bar in the concrete is influenced, therefore, the concrete cushion block plays a very important role in building construction, most of the concrete cushion blocks cannot be adjusted after being firmly welded with the structural steel bar in the existing building construction process, a structural reference side line cannot be accurately controlled when a building steel template is erected, the template is seriously deviated sometimes, the thickness control difficulty of the concrete structure building protective layer is larger, therefore, how to ensure the perfect fit of the cushion block and the template in the installation process of the building template, and the difficulty of controlling the thickness of the building protective layer is always a construction problem.
In addition, most concrete cushion blocks are in surface contact with the template at present, and after the concrete template is demolded, the surface of the concrete cushion block is not smoothly connected with newly poured concrete, so that the appearance quality of the concrete is seriously affected, and the later-stage concrete needs to be repaired manually, so that the construction efficiency is reduced, and the construction cost is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the unable accurate control structure benchmark sideline when building steel form erects, cause the great and template of concrete structure building protective layer thickness control degree of difficulty demolishs back concrete appearance quality and receives technical problem such as influence, a nut formula concrete cushion is provided, the cushion is the halfcylinder, with concrete cushion, built-in nut and supporting bolt as an organic whole, can reduce the later stage building template construction degree of difficulty, effective control building protective layer thickness, make the cushion agree with the concrete perfect of pouring, and easy operation, the accuracy is high.
The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: the utility model provides a nut formula concrete cushion, concrete cushion are the halfcylinder, and the inside nut and separation blade of inlaying of concrete cushion are equipped with, and the separation blade symmetry is fixed in the nut both sides, set up the bolt pore that link up from top to bottom on the concrete cushion, the bolt passes concrete cushion square cross-section and nut threaded connection to stretch into in the bolt pore, the terminal vertical bending of bolt, be used for with structure reinforcing bar fixed connection.
Furthermore, the separation blade is the right angle structure of buckling, the separation blade welding is on the nut.
Further, the nut is a stainless steel outer hexagonal nut, and the nominal diameter of the thread of the nut is 12 mm.
Further, the nominal diameter of the thread of the bolt is 12 mm.
Compared with the prior art, the utility model discloses beneficial effect as follows:
(1) the utility model provides a nut formula concrete cushion, with concrete cushion, built-in nut and bolt as an organic whole, through adjusting concrete cushion, can reduce the later stage building template construction degree of difficulty, accurate control structure benchmark sideline, the protective layer thickness of effective control concrete structure building has characteristics such as simple structure, convenient operation, location accuracy, fix rapidly.
(2) The utility model provides a nut formula concrete cushion, concrete cushion are the halfcylinder, can reduce cushion and template area of contact, and the degree of agreeing with is increased, can guarantee concrete appearance quality to improve the efficiency of construction, reduce construction cost.
(3) The utility model provides a nut formula concrete cushion, separation blade are the right angle structure of buckling, and the welding is on the outer hexagon nut of stainless steel, arranges the concrete cushion inside together with the nut in, can ensure that the nut firmly inlays and puts in the concrete cushion.
(4) The utility model provides a nut formula concrete cushion, the bolt pore does not have the concrete in the below, can ensure that cushion and the concrete perfect agreement of pouring, middle no space.
