Abstract

A kind of sawtooth trowel that can have conventional trowel and rake function concurrently.Its rectangle patter side is designed to zigzag, and a few side keeps complete in addition.In Specific construction process, the trowel of patter side indentation not only has the function of conventional trowel, and can replace rake, and the concreting face of effects on surface hollow flattens roughly.Thus avoid and first require that builder first flattens roughly with rake, then change the careful leveling of trowel, make Specific construction flow process become more simple, for constructor reduces the heavy burdens.

Description

Sawtooth trowel

Art

The utility model relates to a kind of building operations apparatus, especially side indentation, the trowel of rake function can be had both.

Background technology

The instrument that trowel is conventional when being concreting leveling, receipts light, is all widely used at various construction site.

The patter of existing trowel is rectangle mostly, neat in edge, and such patter is conducive to screeding concrete red dog.But due in Specific construction process, usually because concrete paving is fallen uneven, make phase surface presentation hollow shape, larger by conventional trowel leveling difficulty.

So, generally need constructor first to utilize rake first to flatten roughly coagulation face, then carry out meticulousr leveling with trowel, change construction tool so continually, just add difficulty to site operation, add burden to constructor.

Summary of the invention

The deficiency that the concrete surface relatively serious to hollow flatten is difficult in order to overcome existing trowel, the utility model provides the trowel of a kind of side indentation, this kind of trowel not only possesses the function of the careful leveling of conventional trowel, also have the function of rake concurrently, can the concrete of effects on surface hollow flatten roughly.

The utility model solves the technical scheme that its technical problem adopts: design patter is rectangle, and patter inside edge is zigzag, and tooth depth is about near to patter and handle weld, and other three lateral edges keep neat, make it have the function of trowel and rake concurrently.

The beneficial effects of the utility model are, when flattening local surfaces and having the coagulation of hollow, zigzag patter inside trowel not only can be utilized to replace rake, flatten roughly, the patter of other three sides can also be utilized to carry out more careful leveling.Avoid constructor to need to change instrument continually in the middle of Specific construction process.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Accompanying drawing is structure diagram of the present utility model.

1. patters in accompanying drawing, 2. weld metal bar, 3. handle.

Detailed description of the invention

The side of one block length square steel patter longer sides is cut into zigzag, sawtooth dark near-lying mode plate center line, jaggy pitch is from evenly, and other three side keeps complete.Zigzag patter and handle weld by metal welding bar, and pad is in patter central authorities.

In use, use hand control handle, red dog can be contacted with utilizing patter jagged edge, scraping back and forth and taking off, concrete red dog is flattened roughly.Meanwhile, careful leveling can be carried out, receive light with other complete patter side.

Claims (2)

1. a trowel, comprises side with the patter (1) of jagged edge and the handle (3) that is connected with patter (1), it is characterized in that: described patter (1) side indentation.

2. trowel according to claim 1, is characterized in that: patter (1) side presents zigzag, and interdental space is even, metal solder bar (2) place that the nearly patter of tooth depth (1) is connected with handle (3).
