Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a tool for grooving masonry blocks. Background Technology

[0002] High-precision masonry blocks, as a new type of building material, are made from finely ground sand or fly ash as siliceous materials, cement and quicklime as calcareous materials, and aluminum powder (paste) as a foaming agent. The process involves casting, static curing, pre-curing, cutting, and autoclaving. Currently, in various construction projects, these blocks, laid with special mortar, can be used as walls, improving their sound insulation and thermal insulation performance. During construction, grooves for rebar installation need to be created on the blocks to ensure accurate rebar placement. Currently, electric grooving tools are used for grooving; however, due to the high price and weight of these devices, their utilization rate is low and they are inconvenient to handle in situations where grooving strength is not high. Therefore, a manual block grooving tool is designed. Utility Model Content

[0003] The purpose of this invention is to provide a manual block grooving tool.

[0004] This utility model is achieved through the following measures: a block grooving tool, characterized in that it includes two symmetrically arranged guide rods, a mounting plate connecting one end of the two guide rods, a limiting member on the lower end face of the mounting plate that fits against the outer wall of the block, a sliding sleeve slidably arranged on each of the two guide rods, the two sliding sleeves being connected by a sliding plate, a slotted opening on the sliding plate, a stud fixedly arranged on the upper end face of the two sliding sleeves, and an adjusting plate with both ends sleeved on the stud, a nut arranged on the stud and below the adjusting plate, a baffle fixedly arranged on the upper end of the stud, and a spring sleeved on the stud and between the adjusting plate and the baffle, the upper end of the spring being fixed on the baffle and the lower end being fixed on the adjusting plate;

[0005] A serrated grooving blade is fixedly provided on the lower end surface of the adjusting plate, and a screw is provided on the sliding sleeve by means of a threaded connection to the guide rod.

[0006] An arc-shaped handle is fixedly installed on the adjustment plate, and an anti-slip sleeve is fixedly installed on the outer end of the arc-shaped handle.

[0007] The limiting component is a plate that fits against the outer wall of the block.

[0008] The limiting component consists of several rollers tangent to the outer wall of the block, and the upper end of the rollers is fixed to the mounting plate by bolts.

[0009] The grooving cutter is generally semi-circular in shape and its thickness is typically the width of the groove to be cut. The grooving cutter can be welded to the adjusting plate or fixed to the adjusting plate in a detachable manner, such as with bolts.

[0010] An extension plate is provided at one end of the mounting plate facing the arc-shaped handle, and a plurality of rollers are provided on the extension plate. This allows the movement of the grooving cutter to be controlled by the contact between the rollers on the extension plate and the block.

[0011] A fixing rod for easy rotation is fixedly provided on the outer wall of the nut.

[0012] How to use:

[0013] With the upper roller of the extension plate tangential to the side wall of the block, slide the sliding plate according to the desired grooving position to adjust the distance between the grooving blade and the side wall. After measurement, fix it with screws. According to the desired grooving depth, turn the nut to adjust the length of the grooving blade extending from the sliding plate. Then, pull the handle while pressing the adjusting plate to make the roller move along the outer wall of the block, and the grooving blade will groove the block.

[0014] The beneficial effects of the technical solution provided by this utility model embodiment are: simple overall structure and low manufacturing cost; light weight due to the absence of a motor, convenient for use in situations with low construction intensity and easy to handle; can be used as an auxiliary tool when power tools temporarily malfunction; and can realize the adjustment of the distance between the groove and the side wall of the block and the control of the depth.
