Abstract

The invention relates to assembly type buildings, in particular to an assembly type building shear wall sleeve. A method for grouting of the assembly type building shear wall sleeve comprises the steps that 1, a grouting area is isolated into a plurality of bins through rubber strips, the grouting length of each bin is 400-800 mm, and the surrounding of each bin is sealed in a bed-mortar mode with bed-mortar slurry; 2, an obliquely upward diversion pipe is inserted into an upper grouting hole in the upper portion of the sleeve, so that the liquid level difference is increased, and compact grouting is ensured; and 3, grouting is carried out through pressure of a grouting pump. According to the method, the grouting quality is high, and the degree of compactness is high.

Description

A kind of assembled architecture shear wall sleeve grouting method

Technical field

The present invention relates to assembled architecture, particularly relate to assembled architecture shear wall sleeve.

Background technology

Reinforced bar sleeve grouting connects and is connected reinforcing bar and sleeve by the sleeve processed specially and reinforcing bar by injecting the interlocking that coheres between grouting material dependence material, and the degree of compaction of grouting directly affects the safety of sleeve connection.

In reinforced bar sleeve grouting, there is certain pressure in sleeve, in pressure releasing process, grouting material has the process of a backflow, if not having supplementing of grouting material in reflux course, can cause the hollowing that sleeve is in the milk, and Grouted density reduces.

Summary of the invention

Present invention seek to address that the defect of prior art, it is provided that a kind of assembled architecture shear wall sleeve grouting method.Grouting quality of the present invention is good, and degree of compaction is high.

In order to solve above-mentioned technical problem, a kind of assembled architecture shear wall sleeve grouting method, it includes

Step one, uses adhesive tape to be isolated into several storehouses, each storehouse grouting length 400-800mm to grouting region, and the mode of surrounding seat slurry seat slurry seals;

Step 2, upper cartridge grout hole uses mozzle obliquely to insert upper strata grout hole, closely knit to ensure grouting;

Step 3, uses grouting pump machine pressure grouting;

Described a kind of assembled architecture shear wall sleeve grouting method, described step 3 includes

A calculates the volume that need to irrigate joint quantity or grouting space according to drawing, calculates the consumption of grouting material;By weight, the product report that amount of water provides according to producer provides data to grouting material mixing water, uses compression pump pumping;

During b grouting, successively the plasma discharge hole overflowing mortar is clogged with special blocking when grout outlet pulp, when all sleeve plasma discharge holes all have mortar to overflow, stop grouting, and by grouting hole plugging;

C grouting is complete, cleans blender, grouting pump or the utensil such as grouting lance and grout pipe with water immediately.

The present invention carries out specification explanation to the grouting construction of assembled architecture shear wall sleeve, to ensure the grouting quality in filling process, enables filling sleeve node out to meet the performance indications of sleeve connection.

Detailed description of the invention

Below in conjunction with embodiment, this technology is described in further detail and completely:

One assembled architecture shear wall sleeve grouting method of the present invention, it includes

1. the installation of body of wall

Component uses crane lifting, shroud member and reinforcement component to use backing plate to reserve the space of 20mm height, adjusts reinforcing bar and make reinforcing bar in sleeve centre position in lifting.

2. a slurry

Filling in the colloid of 20mm thickness in two component 20mm spaces, adhesive tape fills in distance edge 20mm, then uses BY fast hard seat slurry seat slurry.

3. mozzle is installed

Upper cartridge grout hole uses mozzle obliquely to insert upper strata grout hole.

4. pressure grouting (according to assembled architecture shear wall sleeve grouting technique)

Using grouting pump machine pressure grouting, grouting material is the special grouting material of sleeve, and grouting process is as follows:

1) volume of joint quantity or grouting space need to be irrigated according to drawing calculating, calculate the consumption of grouting material.

2) according to the water consumption mix grouting material calculated, mixing water should meet the regulation of " concrete mixing water standard " (JGJ63).

3), after grouting material stirs, grouting material is poured into grouting pump carries out cementing operations.

4) during grouting, overflow the order of mortar according to grouting and plasma discharge hole, successively the plasma discharge hole overflowing mortar is clogged with special blocking, when all sleeve plasma discharge holes all have mortar to overflow, stop grouting, and by grouting hole plugging.

5) it is in the milk complete, cleans the utensils such as blender, grouting pump and grout pipe immediately with water.

4. the drawing experiment of sleeve after curing cycle

Removing experiment concrete, the degree of compaction using this grouting technique to be in the milk is preferable, and sleeve grouting connector is carried out drawing experiment.Experimental data such as table 1 below:

The grouting of table 1 reinforced bar sleeve connects drawing experimental data

Numbering Fracture position Tensile strength/MPa 1-1 Connect reinforcing bar 609.1 1-2 Connect reinforcing bar 610.0 2-1 Connect reinforcing bar 601.8 2-2 Connect reinforcing bar 617.1

Claims (2)

1. an assembled architecture shear wall sleeve grouting method, it is characterised in that it includes
Step one, uses adhesive tape to be isolated into several storehouses, each storehouse grouting length 400-800mm to grouting region, and the mode of surrounding seat slurry seat slurry seals;
Step 2, upper cartridge grout hole uses mozzle obliquely to insert upper strata grout hole, closely knit to ensure grouting;
Step 3. use grouting pump machine pressure grouting.
A kind of assembled architecture shear wall sleeve grouting method the most according to claim 1, it is characterised in that described step 2 includes
Using mozzle obliquely to insert upper strata grout hole before a grouting, mozzle design height is higher than sleeve top surface, to improve grouting potential difference;
B calculates the volume that need to irrigate joint quantity or grouting space according to drawing, calculates the consumption of grouting material;By weight, the product report that amount of water provides according to producer provides data to grouting material mixing water, uses compression pump pumping;
During c grouting, successively the plasma discharge hole overflowing mortar is clogged with special blocking when grout outlet pulp, when all sleeve plasma discharge holes all have mortar to overflow, stop grouting, and by grouting hole plugging;
D grouting is complete, cleans the utensils such as blender, grouting pump and grout pipe immediately with water.
