Description
Technical field
The utility model relates to a kind of pointers, relate particularly to a kind of pointer suitable for block wall,
The tool mainly applies to constructing brick wall mortar joint jointing, belongs to masonry structure mortar joint quality control technology.
Background technique
When building dry wall at the construction field (site) at present jointing frequently with construction method be plain bar using indefinite form
Or pvc pipe is extruded from, and has following drawback using such construction method, first is that, lack of standard；Due to tool
Ambiguity will lead to none unified specification of the operating result of jointing.Its construction quality is also wanted hardly consistent with specification
It asks, frequently can lead to do over again, such result and will increase engineering construction cost and also waste working sources between invisible；Second is that
Without revolving, arbitrarily replaced using provisional material in constructing operation with certain normative tool,
Itself does not have reusable property yet, requires temporarily to make before each use, which can both waste construction material
Influence whether that the extension of operating time delays the duration again, meanwhile, there is also mortar joint is not mellow and full, mortar is not tight for traditional operation
Real and mortar joint width, deep mixed, when putty cover, grey slit width, deep position, finish coat are easy cracking, and mortar joint is narrow, superficial part position,
Finish coat easy to shell, there are biggish quality problems.
Therefore, need to develop a kind of a kind of practical and high pointer suitable for block wall of functional reliability is
Solve the key point of above-mentioned technical problem.
Summary of the invention
For many shortcomings and deficiencies present in above-mentioned background technique, the utility model is improved and has been created to this
Newly, and it is an object of the present invention to provide one kind can play a kind of specification dry wall jointing working procedure operation, make its standardization, using the dress
Setting can utmostly avoid causing to do over again because of Work tool the reason of, can reasonably save the duration and save project cost, do
To one-pass molding.
Another goal of the invention of the utility model be that by during constructing operation using the design tool due to
Itself structural material using firm durable material production may be implemented that it is allowed repeatedly to be used in turn.Reduce engineering construction behaviour
The cost for making tool meets the economy of itself.
To achieve the above object, the utility model is realized by using following design structure and design scheme
:
As a kind of improvement of the pointer suitable for block wall of the utility model, which includes jointing work
Have ontology (1), is symmetrically extended the locating part (11) equipped with conjoined structure, locating part in the two sides of the pointer ontology (1)
It (11) is arcuate structure；Perpendicular connector (12), connector (12) one end are equipped on the pointer ontology (1)
The middle part of pointer ontology (1) is connected, connector (12) other end connects pointer handle (2).
The improvement above-mentioned as the utility model, the pointer ontology (1) generally " C " character form component should " C " word
Shape component is that round tube scrapes rail, and the jointing width kissing of diameter and block wall which scrapes rail is matched.
The further improvement above-mentioned as the utility model, the connector (12) generally inner hollow or solid
Clava component, the clava component are the external screw rod or screw rod for being internally threaded section.
The further improvement above-mentioned as the utility model, the connector (12) and pointer ontology (1) and hook
Tailor, which has, to be either flexibly connected between handle (2) to be fixedly connected.
The further improvement above-mentioned as the utility model, between the connector (12) and pointer ontology (1)
To be fixedly connected；It is that activity is detachably connected between the connector (12) and pointer handle (2).
The further improvement above-mentioned as the utility model, it is described to be fixedly connected as being welded to connect either directly processing
It is an integral molding structure；The activity is detachably connected as articulated connection, plug-in socket connection either internal and external threads connection.
The again further improvement above-mentioned as the utility model, the generally T-shaped structure of pointer handle (2)
Part is coaxially provided with mounting portion (21) in one end of the T-shaped component, and mounting portion (21) is the cylinder component of inner hollow；
It is equipped with perpendicular hand-held part (22) in the other end of the T-shaped component, hand-held part (22) are equipped with and are adapted therewith
Non-slip mat (221).
The again again further improvement above-mentioned as the utility model, the mounting portion (21) is that external or inside is equipped with
The free end of the screw rod or screw rod of thread segment, the screw rod or screw rod and the free end kissing of connector (12) are with connection；Institute
Stating hand-held part (22) is clava component；The non-slip mat (221) is rubber antiskid pad, and consubstantiality is equipped on the rubber antiskid pad
Several rubber antiskid bumps.
As the utility model it is above-mentioned again be more further improved again, in pointer ontology (1) and pointer handle
Injection molded layers and antirust coat and alert layer is sequentially coated with from the inside to the outside on the outer surface of (2), fluorescent powder is coated in alert layer.
