Description

Mortar initial stage instrument of making level

Technical Field

The utility model relates to a post-processing appliance of whitewash or the like, in particular to a leveling tool for the initial stage of mortar.

Background

The smooth and compact concrete surface can prevent moisture from entering the interior of the concrete to a certain extent, has a certain waterproof effect and has a relatively attractive appearance. Therefore, the exposed surface of the concrete member needs to be smoothed immediately after casting. The leveling is usually made of mortar or plain cement, and after the mortar or the plain cement is spread on the surface of a concrete piece, the concrete piece is leveled, and then is leveled by a wood trowel and a steel trowel to obtain a smooth and compact concrete surface. The most common concrete piece that needs to be smoothed is a concrete floor.

At present, the leveling of the paved mortar, plain ash or concrete is mainly carried out by adopting a mode of scraping a wood board or shoveling the wood board or the plain ash. The efficiency is low and the speed of concrete pouring cannot be kept up with. The method can meet the requirements on occasions with small areas, such as yard floor construction or household floor construction; for occasions with large areas such as factory roads, the problems of rough and flat construction after initial setting of concrete and difficult subsequent fine and flat construction due to too slow construction are faced.

SUMMERY OF THE UTILITY MODEL

The utility model provides a mortar initial stage instrument of making level.

The technical problem to be solved is that: the leveling efficiency by adopting a board leveling or spade leveling mode is low, the leveling can not follow the concrete pouring speed, and the rough leveling and subsequent fine leveling construction difficulty after the initial setting of the concrete can be caused due to the over-slow construction.

In order to solve the technical problem, the utility model adopts the following technical scheme:

the utility model provides a mortar initial stage instrument of making level, includes handle bar and screed-plate, handle bar one end is passed through the damping pivot with the face of screed-plate and is rotated and be connected, damping pivot perpendicular to handle bar sets up.

Further, the handle bar comprises an internal thread sleeve rotatably connected with the leveling plate, and an extension bar inserted in the internal thread sleeve and in threaded connection with the internal thread sleeve.

Further, on the face of screed-plate and the one end that the extension rod was kept away from to the internal thread sleeve has welded the otic placode respectively, the otic placode on the screed-plate and the otic placode setting on the internal thread sleeve are penetrated in the damping pivot.

Further, the cover is equipped with the protective housing that is used for protecting the damping pivot on the internal thread sleeve, the protective housing extends and includes damping pivot parcel to the screed-plate.

Further, the protective shell is of a cylindrical structure with a polygonal cross section, one end of the protective shell is anchored on the inner threaded sleeve, and the other end of the protective shell is anchored on the surface of the leveling plate; the protective shell is made of an elastomer material.

Further, the protective housing is made of silica gel.

Furthermore, the leveling plate is a rectangular manganese steel plate.

The utility model relates to a mortar initial stage instrument of making level compares with prior art, has following beneficial effect:

in the utility model, the handle rod connected with the damping rotating shaft and the leveling plate are used for leveling the mortar, the surface of the leveling plate is attached to the mortar, and the handle rod is held by a worker to drag the leveling plate to retreat, so that the mortar is continuously leveled, and the efficiency is obviously improved; the existence of damping pivot simultaneously for the workman of different heights can both hold the handle pole with comparatively comfortable posture and make level on various topography, reduces workman's fatigue degree and has improved work efficiency, and the contained angle of handle pole and screed-plate can not appear violently changing under the damping, thereby has ensured the quality of making level.

Drawings

FIG. 1 is a schematic structural view of a mortar initial leveling tool according to the present invention;

FIG. 2 is a schematic structural view of the mortar initial leveling tool after the protective shell is removed;

the damping device comprises a leveling plate, a 21-internal thread sleeve, a 22-extension rod, a 3-damping rotating shaft, a 4-lug plate and a 5-protective shell.

Detailed Description

As shown in fig. 1-2, a mortar initial leveling tool comprises a handle rod and a leveling plate 1, wherein one end of the handle rod is rotatably connected with the surface of the leveling plate 1 through a damping rotating shaft 3, and the damping rotating shaft 3 is perpendicular to the handle rod.

The handle bar and the screed 1 are not kept at a fixed angle, so that workers of different heights cannot hold the handle bar at the most comfortable angle during use, and some taller or shorter workers must raise or lower the handle bar during use, which is very difficult to use. If the common pin shaft is adopted to connect the handle rod and the leveling plate 1, the leveling plate 1 needs to be pressed to prevent the leveling plate 1 from moving randomly when in use, so that the worry is very wasted, and meanwhile, marks can be brought to mortar when the terrain changes, so that the damping rotating shaft 3 needs to be adopted.

The utility model discloses the initial stage of mainly used mortar is made level, but also can be used to making level of concrete.

The handle bar includes an internally threaded sleeve 21 rotatably connected to the leveling plate 1, and an extension bar 22 inserted into the internally threaded sleeve 21 and threadedly connected to the internally threaded sleeve 21. Therefore, the extension rods 22 with different lengths can be used for extending the handle rods according to actual conditions, so that the walking area of workers can be suitable for scenes with long distance from the concrete piece.

The ear plates 4 are welded on the surface of the leveling plate 1 and one end, away from the extension rod 22, of the internal thread sleeve 21 respectively, and the damping rotating shaft 3 penetrates through the ear plates 4 on the leveling plate 1 and the ear plates 4 on the internal thread sleeve 21.

The protective shell 5 used for protecting the damping rotating shaft 3 is sleeved on the internal thread sleeve 21, and the protective shell 5 extends towards the leveling plate 1 and wraps the damping rotating shaft 3. The damping rotating shaft 3 is relatively precise equipment and must be wrapped to prevent impurities from entering and affecting the normal operation of the damping rotating shaft.

In the utility model, the protective shell 5 is a cylindrical structure with a polygonal cross section, one end of the protective shell is anchored on the inner thread sleeve 21, and the other end of the protective shell is anchored on the surface of the leveling plate 1; the protective shell 5 is made of an elastomer material. The structure can fully protect the damping rotating shaft 3 and simultaneously can not excessively influence the rotation of the handle rod, and meanwhile, the damping effect is enhanced to a certain extent by the elastomer material.

In this embodiment, the protective shell 5 is made of silica gel so as to maintain elasticity at low temperature, and conventional soft PVC plastic can be used; the leveling plate 1 is a rectangular manganese steel plate which is relatively wear-resistant, but should be washed after use to prevent rusting.

The utility model relates to a mortar initial stage instrument of making level, its use includes following step:

the method comprises the following steps: paving the mortar to be leveled in place;

step two: pasting the leveling plate 1 on mortar, and retreating a hand holding handle rod to level;

step three: after leveling, the leveling plate 1 is washed and cleaned in time.

The above-mentioned embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
