Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a tool used for isolating high-temperature welding slag from a waterproof layer. Background Art

[0002] In construction, polymer waterproofing membranes are widely used for baseboard waterproofing. Polymer waterproofing membranes usually have limited tolerance to high temperatures, and the heat-resistant temperature is generally between 70℃ and 100℃. Usually, steel bar assemblies are laid on the baseboard and welded. During the welding process of the baseboard steel bar assemblies, the high-temperature welding slag generated during the welding process of the baseboard steel bars will directly fall on the waterproofing membranes that are close to them. The welding slag temperature is usually much higher than the tolerance temperature of these polymer materials, so it is easy to cause scalding and damage to the waterproofing membranes, thereby affecting the waterproofing effect. In order to ensure the waterproofing effect of the baseboard, it is imperative to protect the waterproofing membranes, and it is necessary to use isolation devices or other protective measures.

[0003] Since the height spacing between the bottom plate steel bar assembly and the waterproof membrane is small, the isolation protection assembly cannot be effectively placed, so it is difficult to play the role of isolation protection and cannot be deployed and used in a small 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, so that it can be set up and used under the bottom plate steel bar component with a small space and low spacing. Therefore, it is necessary to propose a more reasonable technical solution to solve the technical problems existing in the existing technology. Utility Model Content

[0005] In order to overcome at least one of the defects mentioned above, the utility model proposes a tool for isolating high-temperature welding slag in a waterproof layer, which is arranged through a deformable structure in conjunction with a bottom plate steel bar assembly, so that the welding slag can be smoothly laid and isolated in a low-spacing scenario, thereby improving the convenience of use.

[0006] In order to achieve the above-mentioned purpose, the tool disclosed in the utility model can adopt the following technical solutions:

[0007] A tool for isolating high-temperature welding slag with a waterproof layer, comprising an operating handle, the lower end of which is connected to at least three spreading rods that are bent and deformed in the longitudinal direction, the spreading rods comprising a plurality of mutually hinged spreading rod sections; a flexible isolating member is arranged below the spreading rod and is connected to the front end of the spreading rod.

[0008] The tool disclosed above for isolating high-temperature welding slag can drive the expansion and contraction of the flexible isolation piece through the deformation action of the expansion rod, thereby providing isolation under the bottom plate steel bar group with a smaller interval, which can effectively protect the waterproof layer from damage by welding slag.

[0009] Furthermore, the arrangement of the pole sections will affect the deployment of the spreader rods, and the arrangement is optimized and one of the feasible options is proposed: adjacent pole sections are hinged in the longitudinal direction, and when the spreader rod changes from vertical to bent, it spreads outward with the operating handle as the center, and the deflection angle between adjacent pole sections is less than or equal to 180°. When such a scheme is adopted, components such as articulated balls or articulated shafts are arranged between adjacent pole sections to achieve deflection; and a limited position flange is arranged on the pole section to prevent the deflection angle from exceeding 180°. When this scheme is implemented, the lower end of the spreader rod is easier to pass through the narrow steel bar hole after closing, so it is more practical in construction environments where the steel bar hole is relatively narrow.

[0010] Furthermore, in the present invention, the flexible partition can adopt a variety of solutions, which are not limited to the only one. Here, optimization is made and one feasible option is proposed: the flexible partition includes a fireproof cloth. When such a solution is adopted, the fireproof cloth can be set to a circular shape.

[0011] The structure of the further operating handle can be constructed in various forms, which are not limited to the only one. Here, an optimization is made and one feasible option is proposed: the operating handle includes a connecting rod, a connecting plate is provided at the lower end of the connecting rod, and the spreading rod is hingedly matched with the connecting plate and deflected in the longitudinal direction. When such a solution is adopted, a handle can also be provided above the connecting rod for easy holding operation.

[0012] The above content discloses the structure of the welding slag isolation tool. The utility model also provides a specific isolation method using the tool, which is described as follows:

[0013] A method for isolating high-temperature welding slag with a waterproof layer, using the tool for isolating high-temperature welding slag with a waterproof layer as described above, comprising:

[0014] Place the tool, keep the expansion rod vertical, pass the expansion rod and the flexible isolation piece through the steel bar hole to the waterproof layer, and apply force by pressing the operating handle downward to bend the expansion rod and extend it to all sides along the waterproof layer plane. In this process, the expansion rod drives the flexible isolation piece to spread and expand and isolate the waterproof layer from the bottom steel bar assembly;

[0015] Retract the tool, lift up and stretch the rod to bend it, leave the steel bar hole and return to the vertical state, while driving the flexible isolation piece to be retracted.

[0016] The above content describes a tool structure and an isolation method. The utility model also provides another tool structure, which is described below.

[0017] A tool for isolating high-temperature welding slag with a waterproof layer, comprising an operating handle, the lower end of which is connected to at least three laterally bent and deformed spreading rods, the spreading rods comprising a plurality of mutually hinged spreading rod sections; a flexible isolating piece is arranged below the spreading rod and is connected to the front end of the spreading rod.

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

[0019] Furthermore, the arrangement structure of the spreading rod in this solution is optimized and one feasible option is proposed: adjacent spreading rod sections are hinged in the transverse direction, and when the spreading rod changes from bending to straightening, it spreads outward with the operating handle as the center, and the deflection angle between adjacent spreading rod sections is less than or equal to 180°. When such a solution is adopted, the spreading rod is unfolded outward from the coiled state, which is more convenient to operate and can easily provide a larger isolation area. At the same time, flanges are provided on the spreading rod sections, so that the deflection angle of adjacent spreading rod sections does not exceed 180° after being flexibly unfolded.

[0020] Furthermore, in the present invention, the flexible isolation member can adopt a variety of solutions: the flexible isolation member includes a fireproof cloth.

[0021] Furthermore, the structure of the operation handle can be constructed in various forms, which are not limited to the only one. Here, an optimization is made and one feasible option is proposed: the operation handle includes a connecting rod, a connecting plate is provided at the lower end of the connecting rod, and the opening rod is hingedly matched with the connecting plate and deflected in the longitudinal direction. When such a solution is adopted, a handle can also be provided above the connecting rod for easy holding operation.

[0022] The above content discloses the structure of another welding slag isolation tool. The utility model also provides a specific isolation method of the tool, which is described as follows:

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

[0024] Place the tool, keep the expansion rod bent and coiled, pass the expansion rod and the flexible isolation piece through the steel bar hole to the waterproof layer, rotate the operating handle in the first direction to apply force to gradually stretch the expansion rod and extend it to all sides along the waterproof layer plane. In this process, the expansion rod drives the flexible isolation piece to spread and expand and isolate the waterproof layer from the bottom steel bar assembly;

[0025] The tool is retracted, and the operating handle is rotated in the second direction to apply force to gradually bend and coil the support rod, while driving the flexible isolation piece to be retracted.

[0037] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0038] In view of the fact that the distance between the bottom plate steel bar assembly and the waterproof layer in the prior art is small, which makes it inconvenient to set up a welding slag isolation structure, the following examples are optimized to overcome the defects in the prior art.

[0039] Example 1

[0040] like Figures 1 to 3 As shown, this embodiment provides a tool for isolating high-temperature welding slag with a waterproof layer 6, including an operating handle, the lower end of which is connected to at least three expansion rods 4 that are bent and deformed in the longitudinal direction, and the expansion rods 4 include a plurality of expansion rod sections 401 that are hinged to each other; a flexible isolation member 5 is arranged below the expansion rod 4 and the flexible isolation member 5 is connected to the front end of the expansion rod 4.

[0041] The tool for isolating high-temperature welding slag disclosed in this embodiment can drive the expansion and contraction of the flexible isolation member 5 through the deformation action of the expansion rod 4, thereby providing isolation below the bottom plate steel bar group with a smaller interval, which can effectively protect the waterproof layer 6 from being damaged by welding slag.

[0042] The arrangement of the pole section 401 will affect the expansion of the propping rod 4. The arrangement is optimized and one of the feasible options is adopted: adjacent pole sections 401 are hinged in the longitudinal direction, and when the propping rod 4 changes from vertical to bent, it spreads outward with the operating handle as the center, and the deflection angle between adjacent pole sections 401 is less than or equal to 180°. When such a scheme is adopted, hinges 403 (such as hinge balls or hinge shafts) are arranged between adjacent pole sections 401 to achieve deflection; and a limited flange 402 is arranged on the pole section 401 to prevent the deflection angle from exceeding 180°. When this scheme is implemented, the lower end of the propping rod 4 is easier to pass through the narrow steel bar hole after closing, so it is more practical in a construction environment where the steel bar hole is relatively narrow.

[0043] In this embodiment, the flexible isolation member 5 can adopt a variety of solutions, which are not limited to the only one. This embodiment is optimized and adopts one of the feasible options: the flexible isolation member 5 includes a fireproof cloth. When such a solution is adopted, the fireproof cloth can be set to a circular shape.

[0044] The structure of the operating handle can be constructed in various forms, which are not limited to the only one. This embodiment optimizes and adopts one of the feasible options: the operating handle includes a connecting rod 2, a connecting plate 3 is provided at the lower end of the connecting rod 2, and the spreading rod 4 is hingedly matched with the connecting plate 3 and deflected in the longitudinal direction. When such a solution is adopted, a handle 1 can also be provided above the connecting rod 2 to facilitate holding operation.

[0045] Example 2

[0046] The content of the above embodiment 1 discloses the structure of the welding slag isolation tool. This embodiment also provides a specific isolation method using the tool, which is described as follows:

[0047] A method for isolating high-temperature welding slag from a waterproof layer 6, using the tool for isolating high-temperature welding slag from a waterproof layer 6 as described above, comprising:

[0048] Place the tool, keep the strut 4 vertical, pass the strut 4 and the flexible separator 5 through the steel bar hole to reach the waterproof layer 6, and press down the operating handle to apply force to bend the strut 4 and extend it around along the plane of the waterproof layer 6. During this process, the strut 4 drives the flexible separator 5 to spread out and isolate the waterproof layer 6 from the bottom steel bar assembly 7;

[0049] Retract the tool, lift the operation handle, the strut 4 bends and leaves the steel bar hole and returns to the vertical state, and at the same time drives the flexible separator 5 to retract.

[0050] Embodiment 3

[0051] The content of the above Embodiment 1 and Embodiment 2 describes a tool structure and an isolation method. This embodiment also provides another tool structure, which will be described below.

[0052] As Figures 4 to 6 shown, a tool for isolating high-temperature welding slag from the waterproof layer 6 includes an operating handle. At least three struts 4 that are bent and deformed laterally are connected to the lower end of the operating handle. The strut 4 includes a plurality of strut sections 401 that are hinged to each other; a flexible separator 5 is arranged below the strut 4 and the flexible separator 5 is connected to the front end of the strut 4.

[0053] The tool structure disclosed in this embodiment also uses the deformation action of the strut 4 to guide the flexible separator 5 to unfold, so as to achieve the effect of isolating welding slag.

[0054] The setting structure of the strut 4 in this solution is optimized and one feasible option is adopted: adjacent strut sections 401 are hinged laterally. When the strut 4 changes from bent to straight, it spreads out around the operating handle as the center, and the deflection angle between adjacent strut sections 401 is less than or equal to 180°. When adopting such a solution, the strut 4 unfolds outward from the coiled state, and the operation is more convenient, and it is easy to provide a larger isolation area. At the same time, a flange 402 is provided on the strut section 401, so that the deflection angle between adjacent strut sections 401 does not exceed 180° after the activity expansion.

[0055] In this embodiment, the flexible separator 5 can adopt a variety of solutions: the flexible separator 5 includes a fireproof cloth.

[0056] The structure of the operating handle can be constructed in various forms and is not uniquely limited. This embodiment is optimized and one feasible option is adopted: the operating handle includes a connecting rod 2, a connecting disc 3 is arranged at the lower end of the connecting rod 2, and the strut 4 is hinged and cooperated with the connecting disc 3 and deflects longitudinally. When adopting such a solution, a handle 1 can also be arranged above the connecting rod 2 to facilitate the holding operation.

In this process, the spreading rod 4 drives the flexible isolation member 5 to spread and expand and isolate the waterproof layer 6 from the bottom steel bar assembly 7;

[0061] The tool is retracted, and the operating handle is rotated in the second direction to apply force to gradually bend and coil the support rod 4, while driving the flexible isolation member 5 to be retracted.

[0062] The above are the implementation methods listed in this embodiment, but this embodiment is not limited to the above optional implementation methods. Those skilled in the art can arbitrarily combine the above methods to obtain other various implementation methods. Anyone can derive other various implementation methods under the inspiration of this embodiment.
