Abstract

The utility model relates to a kind of concrete prefabricated cushion block, this cushion block is the trapezium structure that concrete is made, the upper surface of this cushion block is shaped with the vertical slot holding reinforcing bar straight down, to should laterally be shaped with the translot of an accommodation reinforcing bar in the cushion block side below vertical slot, the reinforcing bar being positioned at top is parallel to each other with the reinforcing bar being positioned at below and is in same vertical plane.This cushion block not only plays the effect of bearing bar, simultaneously can control floorslab concrete thickness, effectively can also control thickness of concrete cover, has easy to use and flexible, feature that precision is high.This cushion block is concrete material, well can merge, bonds together with the concrete watering build floor.The utility model structure is simple, design science is reasonable, have make simple, easy to use and flexible, intensity height are indeformable, economical, practical feature.

Description

A kind of concrete prefabricated cushion block
Technical field
The utility model relates to concrete floor pouring technique field, especially a kind of concrete prefabricated cushion block.
Background technology
When concrete floor is built; need first to be fixed reinforcing bar; usually anyhow staggered reinforcing bar adopts finer wire colligation; the reinforcing bar of colligation is due to the artificial bracing frame trampling or adopt insufficient strength; cause bracing frame to be out of shape and make floor steel bar dipping and heaving, rebar spacing alters a great deal, and directly affects the protective layer thickness of floor steel bar; some reinforcing bars are even outside exposed, form common quality defect.On the other hand, when building floor concrete, traditional way is artificial bracing wire, causes very large error in practical operation, causes the concrete thickness of flooring uneven.
Through retrieval, find one section of patent document relevant to present patent application: concrete floor steel bar support, notification number (CN202718296U), which disclose a kind of metal to be made of one piece the Steel bar rack that can independently stand, the upper reinforcement Support that this Steel bar rack upper end tool one caves in, lower end Curved Continuous is converted into two feets, a recessed reinforced bar support district, bottom in bending place, need not support by appurtenances such as traditional lower rebar cushion blocks, in concrete floor engineering, can support simultaneously, lower rebar, except construction is simpler and easy, the support effect of its Support is better than again the reinforcing steel supporting machine commonly used.
Contrasted by technical characteristic, above-mentioned open source literature adopts bar bending to be made into bracing frame, carries out welding support needing the reinforcing bar supported, the reinforcing bar amount that this bracing frame expends is large, cost of manufacture is relatively high, and can only provide a supporting role reinforcing bar, can not control slab thickness.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art; a kind of concrete prefabricated cushion block that can control floorslab concrete thickness, effectively can control again upper and lower skin concrete cover to reinforcement thickness is provided; this cushion block makes simple, easy to use and flexible, has that sufficient intensity, precision are high, economical, practical feature.
Scheme of the present utility model is achieved in that
A kind of concrete prefabricated cushion block, this cushion block is the trapezium structure that concrete is made, the upper surface of this cushion block is shaped with the vertical slot holding reinforcing bar straight down, to should laterally be shaped with the translot of an accommodation reinforcing bar in the cushion block side below vertical slot, the reinforcing bar being positioned at top is parallel to each other with the reinforcing bar being positioned at below and is in same vertical plane.
And the height of described cushion block is the thickness of floor, the length of described vertical slot is the diameter sum of protective layer thickness and reinforcing bar.
Advantage of the present utility model and good effect are:
1, this cushion block not only plays the effect of bearing bar, simultaneously can control floorslab concrete thickness, effectively can also control thickness of concrete cover, has easy to use and flexible, feature that precision is high.
2, this cushion block is concrete material, well can merge, bonds together with the concrete watering build floor.
3, simple, the design science of the utility model structure is reasonable, have make simple, easy to use and flexible, intensity height are indeformable, economical, practical feature.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail.
A kind of concrete prefabricated cushion block, as shown in Figure 1 and Figure 2, the trapezium structure that this cushion block 1 is made for concrete, the upper surface of this cushion block is shaped with the vertical slot 2 holding reinforcing bar 3 straight down, to should laterally be shaped with the translot 4 of an accommodation reinforcing bar in the cushion block side below vertical slot, the reinforcing bar (i.e. epithelium reinforcing bar) being positioned at top is parallel to each other with the reinforcing bar (i.e. hypodermis reinforcing bar) below being positioned at and is in same vertical plane.
In the present embodiment, as shown in Figure 1, the height A of this cushion block is the thickness of floor, and the length B of vertical slot is the diameter sum of epithelium thickness of protection tier and reinforcing bar, and C is hypodermis thickness of protection tier.This cushion block effectively can control upper and lower skin concrete cover to reinforcement thickness, can control again the thickness of floor, has easy to use and flexible, feature that precision is high.
The preparation method of this cushion block is:
Use the die cavity of waste and old template construct cushion block, then concreting, the concrete strength of described cushion block lower than the concrete strength of flooring requirement, can not be cushion block after shaping.
The using method of this cushion block is:
By this cushion block horizontal positioned, and in vertical slot and translot, reinforcing bar is installed, and then carries out concrete building.
The utility model has the advantages of for:
This cushion block not only plays the effect of bearing bar, simultaneously can control floorslab concrete thickness, effectively can also control thickness of concrete cover, has easy to use and flexible, feature that precision is high.In addition, this cushion block is concrete material, well can merge, bonds together with the concrete watering build floor.The utility model structure is simple, design science is reasonable, have make simple, easy to use and flexible, intensity height are indeformable, economical, practical feature.
It is emphasized that; embodiment described in the utility model is illustrative; instead of it is determinate; therefore the utility model comprises the embodiment be not limited to described in detailed description of the invention; every other embodiments drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope of the utility model protection equally.
