Description

Technical Field

[0001] The utility model belongs to the technical field of construction equipment, and particularly relates to a chamfering device for inverted arcs and R angles at the waterproof internal corners of roofs. Background Art

[0002] At present, arc chamfering and R chamfering are used in roofs, basements, and multi-water rooms. During the construction process, arc chamfers, R angles, and bevel angles need to be made at the internal corners of the waterproof project base and the cement mortar roof to facilitate the laying of waterproof coiled materials and prevent the coiled materials from cracking or breaking. Before the waterproof construction, the internal corners of the base need to be processed into arcs. Especially in the excellent practice of roofing, the large R angle has a good appearance effect after being plastered and polished, and at the same time, the effective adhesion between the waterproof material and the base is improved.

[0003] In traditional construction, traditional manual trowel-type plastering tools or arc chamfering and R angle plastering tools are mostly used for construction. Although the arc chamfering and R angle have been improved to a certain extent, the following problems will be faced:

[0004] 1) When workers use trowel-type plastering tools, multiple passes are required for forming, and repair is needed after construction. The repeated plastering construction efficiency is low, and the materials need to be transported back and forth. Affected by the temperature, it is not advisable to prepare too much materials at one time. The construction section is short, or additional workers need to be added, consuming a lot of manpower.

[0005] 2) During construction, the materials are spread on the working surface, resulting in serious material waste and being not conducive to the management of a civilized construction site.

[0006] 3) During the construction process, the workers' techniques are inconsistent. After construction, problems such as inconsistent arc radian, non-uniform upper lines, hollowing, and unreliable bonding with the base may occur.

[0007] 4) During the construction process, when workers use trowel-type plastering tools, the materials need to be transported back and forth, requiring a sufficient working surface to stack materials. It is greatly affected by the site, and it is a pure manual operation.

[0008] 5) After construction, the arc corners and R angles are not smooth, and the formed appearance quality is poor. Summary of the Utility Model

[0009] The technical problem to be solved by the utility model is to provide a chamfering device for inverted arcs and R angles at the waterproof internal corners of roofs, which has a simple structure, is small and flexible, is convenient and fast in construction, and has a good construction effect, aiming at the deficiencies in the above-mentioned existing technology.

The bottom of the main frame is provided with directional wheels, and a mortar hopper is arranged on one side. The bottom of the mortar hopper is an open structure, and arc structures are formed on both lower sides thereof. Inside the cavity of the mortar hopper, a vibrator is arranged on the side connected to the main frame, and the vibrator is connected to a mobile power source.

[0012] Preferably, hopper fastening brackets fixedly connected to both sides of the main frame are arranged on both sides of the mortar hopper.

[0027] As Figure 1 shown, the chamfering device for the roof waterproof internal corner inverted arc and R - angle of the present utility model includes a main frame 1. A directional wheel 3 is provided at the bottom of the main frame 1, and a mortar hopper 2 is provided on one side. The bottom of the mortar hopper 2 is an open structure, and arc structures are formed at both lower sides thereof. A vibrator is provided in the inner cavity of the mortar hopper 2 and on the side connected to the main frame 1.

[0028] In one embodiment, the vibrator selects a 12v 0.5A motor. When using the device, it is connected to a mobile power source and equipped with a separate switch to control start - stop.

[0029] When using the chamfering device of the present application during construction, the mortar hopper 2 of the device is closely attached to the wall. The mortar material used for chamfering is filled into the mortar hopper 2 at one time to fill the hopper. Start the vibrator, and rely on the bottom directional wheel 4 to push the device forward, so that the chamfer can be formed at one time. When the mortar material is used up to half, the material can be replenished in time, improving work efficiency. Only 2 operators are required to implement it, greatly saving labor, saving time and effort, improving work efficiency, and saving costs.

[0030] In one embodiment, hopper fastening brackets 4 fixedly connected to both sides of the main frame 1 are provided on both sides of the mortar hopper 2. In order to achieve the best stability effect, the hopper fastening bracket 4 of the present application is designed as a triangular structure, but it is not limited to this structure.
