Abstract
The invention discloses a kind of grout sleeves for reinforcing bar connection, including frustum of a cone sleeve；The frustum of a cone sleeve includes upper table surface, side wall, following table and cavity；The side wall of the frustum of a cone sleeve is equipped with grout nipple；The grout nipple and cavity connection；The upper table surface is equipped with reinforcement installation hole；The following table is equipped with seal mouth ring；The upper table surface and following table are separately connected a reinforcing bar.The grout sleeve main body of the application uses circular cone structure, when under tension, sleeve conical cavity being capable of banding anchoring body, bear certain pressure in its surface, it is shared to participate in external broach, from the switching performance for structurally improving sleeve, while barrel bore volume is bigger with respect to conventional sleeve, compactness is easier to control when grouting construction, improves connection construction q&r energy.
Description
Technical field
The present invention relates to infrastructure construction fields, more particularly, to a kind of grout sleeve for reinforcing bar connection.
Background technique
The inner cavity of conventional sleeve is relatively small, and in grouting construction, compactness is not easily controlled, be easy to appear grouting material with
The problems such as cavity wall bond quality is poor, meanwhile, the sleeve of existing design uses upper and lower vertical structure, and tensile property is poor, for
The reinforcing bar of connection is in its stretching mainly by the cohesive force between grouting material and reinforcing bar and between grouting material and sleeve come tension
It stretches, tensile property is poor.
Summary of the invention
Problem to be solved by this invention is, for it is above-mentioned in the prior art the shortcomings that, propose a kind of to connect for reinforcing bar
Grout sleeve, for improving the cementitiousness of grouting material and cavity wall, while making grouting construction more easily closely knit, the company of improving
Connect construction quality, unfailing performance and tensile property.
To solve the above problems, the scheme that the present invention uses is as follows: a kind of grout sleeve for reinforcing bar connection, feature
It is, including frustum of a cone sleeve；The frustum of a cone sleeve includes upper table surface, side wall, following table and cavity；The frustum of a cone sleeve
Side wall be equipped with grout nipple；The grout nipple and cavity connection；The upper table surface is equipped with reinforcement installation hole；The following table is set
There is seal mouth ring；The upper table surface and following table are separately connected a reinforcing bar.
Further, the grout sleeve according to above-mentioned design scheme for reinforcing bar connection, which is characterized in that the side wall
Outside is equipped with stiffener ring.
Further, the grout sleeve according to above-mentioned design scheme for reinforcing bar connection, which is characterized in that the reinforcing bar
Mounting hole is threaded hole.
Further, the grout sleeve according to above-mentioned design scheme for reinforcing bar connection, which is characterized in that the leave from office
The reinforcing bar of face connection penetrates in cavity.
Further, the grout sleeve according to above-mentioned design scheme for reinforcing bar connection, which is characterized in that the grouting
There are two mouth is set, it is separately positioned on the upper and lower ends of side wall.
Technical effect of the invention is as follows: the reinforcing bar connection grout sleeve of the application builds up intracavitary grouting material with bar pouring
For an entirety, i.e. anchoring body, when under tension, sleeve conical cavity can banding anchoring body, surface is born certain
Pressure, shared to participate in external broach, from the switching performance for structurally improving sleeve.And work as grouting material pouring construction not
Good, when grouting material is with cavity wall bond quality difference, such tube conformation still is able to guarantee switching performance, unless sleeve itself destroys
Or internal anchoring body grouting material crushing, and both intensity are very high, are generally not in destroy.
Compared to the sleeve of traditional structure, the sleeve of the design works it out improvement in structure, by designing tube-in-tube structure
For circular cone structure, so that the grout sleeve of the application not only passes through the cohesive force between grouting and reinforcing bar and obtains tensile property,
Also by the sleeve of circular cone structure concrete grouting is pressurized to improve sleeve tensile property.
Further, stiffener ring is arranged on sleeve outer wall, plays banding, cooperatively undertakes barrel with barrel
Pressure plays metal material tensile strength height characteristic, improves sleeve load-carrying properties.The body of the cavity of the grout sleeve of the application
The opposite conventional sleeve of product is bigger, and compactness is easier to control when grouting construction, improves connection construction q&r energy.Together
When grout sleeve the reinforcement installation hole of upper table surface be threaded reinforced hole, the reinforcing bar of threaded end can directly be twisted when construction
Enter, switching performance is reliable, easy for construction.
Detailed description of the invention
Fig. 1 is grout sleeve structural schematic diagram.
Fig. 2 is that grout sleeve connects the structural schematic diagram after two reinforcing bars.
Wherein, 1 it is upper table surface, 2 be following table, 3 be side wall, 4 be cavity, 5 be grout nipple, 6 be reinforcement installation hole, 7 is
Stiffener ring.
Specific embodiment
The present invention is described in further details with reference to the accompanying drawing.
Embodiment 1: a kind of grout sleeve for reinforcing bar connection, including frustum of a cone sleeve；The frustum of a cone sleeve includes
Upper table surface, side wall, following table and cavity；The side wall of the frustum of a cone sleeve is equipped with grout nipple；The grout nipple and cavity join
It is logical；The upper table surface is equipped with reinforcement installation hole；The following table is equipped with seal mouth ring；The upper table surface and following table are separately connected one
Reinforcing bar.
The application is by being arranged the frustum of a cone sleeve of a truncated cone shape, so that having relative to conventional sleeve bigger
Cavity volume.Enable what is be more easier in grouting construction to control compactness, improve connection construction quality and
Unfailing performance.
Embodiment 2: a kind of grout sleeve for reinforcing bar connection, including frustum of a cone sleeve；The frustum of a cone sleeve includes
Upper table surface, side wall, following table and cavity；The side wall of the frustum of a cone sleeve is equipped with grout nipple；The grout nipple and cavity join
It is logical；The upper table surface is equipped with reinforcement installation hole；The following table is equipped with seal mouth ring；The upper table surface and following table are separately connected one
Reinforcing bar, the side-wall outer side are equipped with stiffener ring, and the reinforcement installation hole is threaded hole, and the reinforcing bar of the following table connection is worn
Enter in cavity, there are two the grout nipple is set, is separately positioned on the upper and lower ends of side wall.
The grout sleeve of the application uses circular cone structure, and first will when grout nipple is arranged on its side wall in construction
Reinforcing bar 1 is screwed into threaded reinforcement installation hole, then reinforcing bar 2 is inserted into the following table of sleeve, and reinforcing bar 2 is inserted into cavity,
Sealing ring seal following table is utilized simultaneously.Finally grouting material is injected from grout nipple.Completion pours.The grout sleeve of the application passes through
The grouting construction that grout nipple is is set more convenient on side wall, is more easier simultaneously for the control of compactness.It will add simultaneously
Strong reinforced steel bar ring is arranged on sleeve outer wall, plays banding, and barrel pressure is cooperatively undertaken with barrel, and it is anti-to play metal material
Tensile strength height characteristic improves sleeve load-carrying properties.
