Abstract
The utility model relates to a reinforced bar cushion block with high bearing capacity, which is used in constructing armored concrete structures and is used as a lower portion horizontal supporting cushion block of reinforced skeleton frames. The steel bar cushion block with high bearing capacity is characterized in that saw teeth (2) are arranged on one end portion of a tube (1), the material of the tube (1) is plastic, and the length of the tube (1) is corresponding to the thickness of a reinforced bar protective layer. The steel bar cushion block with high bearing capacity is characterized in that the structure is simple, the bearing capacity is big, and the structure surface after being shaped is artistic.
Description
Technical field
The utility model relates to a kind of high-bearing capacity reinforcing bar cushion block, is used for structure of reinforced concrete, as the lower horizontal support cushion block of cage of reinforcement.
Background technology
In structure of reinforced concrete; for guaranteeing the protective layer thickness of steel bar stress; generally adopt the plain concrete cushion block of binding 50 * 50 prefabricated * h (thickness of protection tier) mm in the outside of steel bar stress; and the intensity of plain concrete cushion block generally can't reach C30, and each cushion block can only bear the weight that is no more than 75kg.Reinforcement ratio is generally than higher in the large box girder of the large foundation of industrial construction and bridge engineering, if bottom reinforcement bars is with common plain concrete cushion block, when single cushion block load-bearing surpasses 75kg, cage of reinforcement certainly will occur and tie up the back cushion block, want again cage of reinforcement to be lifted very difficulty with regard to crushed situation.Make cushion block if use steel bar end instead, the problem of back from the body structure surface corrosion to inner steel bar stress of can making moist again not only influences structural safety but also influence presentation quality, and job specfication does not allow yet.
Summary of the invention
The purpose of this utility model is to provide that a kind of simple in structure, bearing capacity is big, body structure surface high-bearing capacity reinforcing bar cushion block attractive in appearance after the moulding.
To achieve these goals, the technical solution of the utility model is: a kind of high-bearing capacity reinforcing bar cushion block, it is characterized in that it is that an end of body 1 is provided with sawtooth 2, and the material of body 1 is plastics; The length of body 1 is corresponding with thickness of protection tier.
The length of body 1 is 30mm, and the length of sawtooth 2 is 15mm, and the external diameter of body 1 is 50mm.
The beneficial effects of the utility model are:
1, this cushion block is simple in structure;
2, bearing capacity is big, not cracky: each can bear the weight of minimum 120kg this cushion block, and general cage of reinforcement this cushion block of can not crushing also can suitably strengthen the spacing of placing this cushion block according to the load-bearing situation;
3, body structure surface is attractive in appearance after the moulding: adopt plastics, and not corrosion of body structure surface, body structure surface is attractive in appearance; During this cushion block bearing bar bone, sawtooth is (end is processed to zigzag in the outer part) in the outer part, uses the works surface naked eyes of this cushion block construction not see cushion block substantially; Because the material color of PPR water service pipe and concrete all are light grey, use the works surface naked eyes of this cushion block construction not see aberration substantially simultaneously;
4, make simple: by thickness of protection tier the PPR water service pipe is sawn into segment with common hacksaw, and an end is slit into zigzag gets final product;
5, expense is saved: each cushion block cost of materials adds production costs about 0.10 yuan.
It is heavier that this cushion block is suitable for use in cage of reinforcement, and the cushion block requirement for bearing capacity than higher structure of reinforced concrete, and is used as cage of reinforcement bottom support cushion block in the very high clear-water concrete structure reinforcing bars of structure appearance requirement is installed.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1;
Among the figure: 1-body, 2-sawtooth; The unit of data is mm among the figure.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of high-bearing capacity reinforcing bar cushion block, it is provided with sawtooth 2 for an end of body 1, the material of body 1 be plastics as: adopt polypropylene random copolymer pipe (be the PPR pipe, or claim the PPR water service pipe), an end be slit into zigzag; The length of body 1 corresponding with thickness of protection tier h (as: length of body 1 is 30mm, and the length of sawtooth 2 is 15mm, and the external diameter φ of body 1 is 50mm).
Claims (3)
1. high-bearing capacity reinforcing bar cushion block is characterized in that it is that an end of body (1) is provided with sawtooth (2), and the material of body (1) is plastics; The length of body (1) is corresponding with thickness of protection tier.
2. high-bearing capacity reinforcing bar cushion block according to claim 1 is characterized in that: the length of body (1) is 30mm, and the length of sawtooth (2) is 15mm, and the external diameter of body (1) is 50mm.
