Abstract

The invention discloses a combined grouting sleeve, which comprises a first grouting sleeve and a plurality of second grouting sleeves, wherein the second grouting sleeves are symmetrically arranged at the two sides of the first grouting sleeve; a grouting cavity is formed in each of the first grouting sleeve and the second grouting sleeves; the lower part of each grouting cavity is a sleeve lower opening connected with a first steel bar; the upper part of each grouting cavity is a sleeve upper opening in which a second steel bar is inserted; a grouting opening and a first slurry outlet are formed in the first grouting sleeve; only a second slurry outlet is formed in each of the second grouting sleeves; a communication region is arranged on the periphery of the sleeve lower openings of the first grouting sleeve and the second grouting sleeves; and a plug is arranged around the communication region. The combined grouting sleeve has the advantages that the construction speed is accelerated; in addition, little slurry is leaked; the plugging is in time; all grouting regions are fully injected in one step; the grouting fullness is ensured; the construction quality is improved; and the combined grouting sleeve is worthy of being popularized.

Description

A kind of Combined grouting sleeve and construction method thereof
Technical field
The present invention relates to a kind of bar connecting apparatus and using method thereof, be specifically related to a kind of Combined grouting sleeve and construction method thereof.
Background technology
In assembled architecture, the connection of shear wall is by injecting high strength sleeve grouting material to be connected with lower rebar by slip casting sleeve, when injecting grouting material, due to the pressure of slurry filling machine, to add very greatly grout sleeve very little, grout sleeve needs the grouting port below timely shutoff and grout outlet above when filling grouting material, this is shutoff easy spillage and troublesome poeration not in time, the bad grouting material of shutoff has backflow phenomenon to make sleeve leakiness, causes engineering defective.
Summary of the invention
For making up the deficiencies in the prior art, the invention provides a kind of speed of application fast, the Combined grouting sleeve that grouting quality is high and construction method thereof.
The present invention is achieved through the following technical solutions:
A kind of Combined grouting sleeve, its special character is: comprise the first grout sleeve and some second grout sleeves being symmetrically arranged amongst the first grout sleeve both sides, described first grout sleeve and the second grout sleeve inside are grouting cavity, bottom is the sleeve end opening of connection first reinforcing bar, and top is that the sleeve of insertion second reinforcing bar is suitable for reading; Described first grout sleeve is provided with grouting port and the first grout outlet, and the second grout sleeve only has the second grout outlet; The sleeve end opening surrounding of described first grout sleeve and the second grout sleeve is through district, establishes shutoff around through district.
The construction method of a kind of Combined grouting sleeve of the present invention, comprises the following steps:
(1) by suitable for reading for the sleeve of the first grout sleeve and the second grout sleeve with the second steel concrete supporting, the first reinforcing bar inserts sleeve end opening;
(2) adopt slurry filling machine from the grouting port slip casting of the first grout sleeve, slurry enters through district from grouting port, from sleeve end opening, the second grout sleeve is filled grout material through through district, and the first grout sleeve is filled grout material from grouting port by slurry simultaneously;
(3) shutoff first grout outlet and the second grout outlet.
The invention has the beneficial effects as follows: the present invention is from the grouting port grouting of a middle sleeve, by through district, the sleeve on both sides is filled slurry, both sides sleeve only needs shutoff grout outlet, not only increase speed of application like this, and the few shutoff of spillage is timely, the whole side property in grouting region fills the full weight that ensure that grouting material, improves construction quality.
Accompanying drawing explanation
Accompanying drawing 1 is main TV structure schematic diagram of the present invention.
Accompanying drawing 2 is right TV structure schematic diagrames of the present invention.
Accompanying drawing 3 is plan structure schematic diagrames of the present invention.
In figure, 1 first grout sleeve, 2 second grout sleeves, 3 grouting cavitys, 4 sleeve end openings, 5 sleeves are suitable for reading, 6 grouting ports, 7 first grout outlets, 8 second grout outlets, 9 through districts, 10 shutoff.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Accompanying drawing is a kind of detailed description of the invention of the present invention.This embodiment comprises the first grout sleeve 1 and is symmetrically arranged amongst four second grout sleeves 2 on the first grout sleeve 1 both sides, first grout sleeve 1 and the second grout sleeve 2 inside are grouting cavity 3, bottom is the sleeve end opening 4 of connection first reinforcing bar, and top is the sleeve suitable for reading 5 of insertion second reinforcing bar; First grout sleeve 1 is provided with and grouting port 6 and the first grout outlet 7, second grout sleeve 2 only have the second grout outlet 8 does not establish grouting port; Sleeve end opening 5 surrounding of the first grout sleeve 1 and the second grout sleeve 2 is through district 9, is provided with airtight shutoff 10 and prevents slurry from overflowing around through district 9.
When being in the milk, first by the sleeve suitable for reading 5 of the first grout sleeve 1 and the second grout sleeve 2 and the second steel concrete supporting, the first reinforcing bar inserts sleeve end opening 4; Then adopt slurry filling machine from grouting port 6 slip casting of the first grout sleeve 1, slurry enters through district 9 from grouting port 6, whole through district 9 filled by slurry, from sleeve end opening 4, second grout sleeve 2 is filled grout material through through district 9, the first grout sleeve 1 is filled grout material from grouting port 6 by slurry simultaneously; Last shutoff first grout outlet 7, second grout outlet 8 and grouting port 6 rapidly, because four the second grout sleeves 2 do not establish grouting port, grouting region fills by grouting port 6 is disposable, ensure that the full weight of grouting material, save the step of shutoff second grout sleeve 2 grouting port, not only effectively can improve speed of application, and shutoff is timely, spillage is few, and construction quality is high.
