Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a tool and method for isolating high-temperature welding slag from a waterproof layer. BACKGROUND

[0002] In building construction, polymer waterproofing membranes are widely used for floor waterproofing. Polymer waterproofing membranes generally have limited resistance to high temperatures, with a heat-resistant temperature of typically 70-100℃. Typically, steel reinforcement components are laid on the floor and welded. During the welding of the floor steel reinforcement components, high-temperature welding slag generated during the welding of the floor steel reinforcement components will directly fall on the waterproofing membrane that is relatively close, and the temperature of the welding slag is usually much higher than the tolerance temperature of these polymer materials, thus easily causing burns and damage to the waterproofing membrane, thereby affecting the waterproofing effect. In order to ensure the effect of floor waterproofing, it is imperative to protect the waterproofing membrane, and it is necessary to use isolation devices or other protective measures.

[0003] Due to the small height distance between the floor steel reinforcement components and the waterproofing membrane, it is not possible to effectively place an isolation protection component, so it is difficult to play an isolation protection role, and it is not possible to be used in a narrow space.

[0004] It can be seen that the current welding slag isolation scheme still has room for improvement and should be optimized to improve the convenience of using the isolation component, making it easy to set up and use under a floor steel reinforcement component with a small distance. Therefore, a more reasonable technical solution is needed to solve the technical problems in the prior art. SUMMARY

[0005] To at least overcome one of the above-mentioned defects, the present application proposes a tool and method for isolating high-temperature welding slag from a waterproof layer, which is set up by a deformable structure cooperating with the floor steel reinforcement components, so as to smoothly lay and isolate the welding slag in a low-distance scenario, improving the convenience of use.

[0006] In order to achieve the above-mentioned purpose, the tool disclosed in the present application can adopt the following technical solution:

[0007] A tool for isolating high-temperature welding slag from a waterproof layer, comprising an operating handle, the lower end of the operating handle being connected to at least three longitudinally bent and deformed spreading rods, the spreading rods comprising a plurality of hingedly connected spreading rod segments; a flexible isolation member is arranged below the spreading rods and connected to the front end of the spreading rods.

[0008] The tool for isolating high-temperature welding slag disclosed above can drive the expansion and contraction of the flexible isolation member through the deformation action of the spreading rods, so as to set up an isolation under a floor steel reinforcement component with a small distance, which can effectively protect the waterproof layer from damage by welding slag.

[0009] Further, the setting mode of the strut rod section affects the expansion of the strut rod, and the setting mode is optimized and one feasible selection is proposed: adjacent strut rod sections are hinged in the longitudinal direction, and spread outward with the operating handle as the center when the strut rod changes from vertical to bent, and the deflection angle between adjacent strut rod sections is less than or equal to 180°. When this scheme is adopted, a hinge ball or a hinge shaft or the like is arranged between adjacent strut rod sections to realize deflection; and a limiting flange is arranged on the strut rod section to prevent the deflection angle from exceeding 180°. When this scheme is implemented, the lower end of the strut rod is more easily inserted through the narrow steel bar hole after being folded, and therefore the tool is more practical in a construction environment where the steel bar hole is relatively narrow.

[0010] Further, in the present application, the flexible isolation member can adopt various schemes and is not uniquely limited, and one feasible selection is optimized and proposed here: the flexible isolation member comprises fireproof cloth. When this scheme is adopted, the fireproof cloth can be arranged in a circular shape.

[0011] Further, the structure of the operating handle can be constructed in various forms and is not uniquely limited, and one feasible selection is optimized and proposed here: the operating handle comprises a connecting rod, the lower end of the connecting rod is provided with a connecting disc, the strut rod is hingedly connected to the connecting disc and is deflected in the longitudinal direction. When this scheme is adopted, a handle can also be arranged above the connecting rod to facilitate holding operation.

[0012] The above disclosure relates to the structure of the slag isolation tool, and the present application also provides a specific isolation method using the tool, which is described as follows:

[0013] A method for isolating high-temperature welding slag from a waterproof layer, which adopts the tool for isolating high-temperature welding slag from a waterproof layer described above, comprising:

[0015] The tool is retrieved, the operating handle is lifted, the strut rod is bent and then withdrawn from the steel bar hole and returned to the vertical state, and the flexible isolation member is also withdrawn.

[0018] The tool structure disclosed herein also uses the deformation action of the expansion rod to guide the flexible isolation member to expand, thereby achieving the effect of isolating the welding slag.

[0019] Further, the setting structure of the expansion rod in the present solution is optimized and one feasible option is proposed: the adjacent expansion rod segments are hinged in the transverse direction, and when the expansion rod changes from bending to flatness, it spreads outward around the operating handle, and the deflection angle between the adjacent expansion rod segments is less than or equal to 180°. When this solution is adopted, the expansion rod expands outward from the coiled state, and it is more convenient to operate and can provide a larger isolation area. At the same time, the flange is arranged on the expansion rod segment, so that the deflection angle between the adjacent expansion rod segments does not exceed 180° after the expansion rod segments are expanded.

[0020] Further, in the present solution, the flexible isolation member can adopt various solutions: the flexible isolation member includes fireproof cloth.

[0021] Further, the structure of the operating handle can be constructed in various forms, which is not uniquely limited, and one feasible option is optimized and proposed herein: the operating handle includes a connecting rod, the lower end of the connecting rod is provided with a connecting disc, and the expansion rod is hingedly connected to the connecting disc and deflects in the longitudinal direction. When this solution is adopted, a handle can also be arranged above the connecting rod to facilitate holding and operating.

[0022] The above disclosure discloses another structure of a welding slag isolation tool, and the present solution also provides a specific isolation method for the tool, which is described as follows:

[0023] A method for isolating high-temperature welding slag from a waterproof layer, the tool for isolating high-temperature welding slag from a waterproof layer described above, comprising:

[0024] Place the tool, keep the expansion rod coiled, pass the expansion rod and the flexible isolation member through the steel bar hole to the waterproof layer, and rotate the operating handle in the first direction to force the expansion rod to gradually stretch and extend around the waterproof layer plane, during which the expansion rod drives the flexible isolation member to spread and isolate the waterproof layer from the bottom steel bar assembly;

[0025] Retrieve the tool, rotate the operating handle in the second direction to force the expansion rod to gradually coil, while driving the flexible isolation member to retract.

[0026] Compared with the prior art, some beneficial effects of the technical solution of the present solution include:

[0027] In the present solution, the action of the expansion rod can drive the flexible isolation member to expand or retract, so as to set a welding slag isolation structure at a steel bar cage assembly with a small space and small spacing, thereby protecting the waterproof layer below the bottom plate steel bar assembly and ensuring the waterproof effect.
