Description

Technical Field

[0001] The invention relates to the technical field of building construction, and more particularly to a waterproof protective layer anti-falling device. Background Art

[0002] A waterproof protective layer is a material layer or structure used to prevent water penetration or erosion, and is widely used in construction, industry, electronics and other fields. Its core function is to isolate water from contact with other substances, thereby protecting the substrate from moisture, corrosion or structural damage.

[0003] Currently in the construction field, the waterproof protective layer is not firmly fixed by mortar and watering. It is easy to fall off during backfilling and cannot play a role in waterproofing. This greatly reduces the waterproof quality of the exterior wall, reduces work efficiency, and causes a waste of construction costs. Summary of the invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a device for preventing the waterproof protective layer from falling off, which improves work efficiency, saves construction costs, and improves the quality of waterproof construction.

[0005] The present invention adopts the following technical solution:

[0006] A waterproof protective layer anti-falling device comprises a flat iron, a fixing buckle, a push rod and a butterfly nut. The upper end of the flat iron is provided with a through hole, the lower end of the flat iron is pre-buried in concrete, the upper end of the push rod passes through the through hole of the flat iron, the fixing buckle is installed at the end of the push rod, and the butterfly nut is threadedly connected to the push rod.

[0007] Furthermore, the push rod includes rod one, rod two and rod three, rod one and rod three are parallel, rod two connects rod one and rod three, rod two is perpendicular to rod one, the length of rod one is greater than the length of rod three, rod three is located at the lower end of rod one, and the fixing buckle is installed at the end of rod three.

[0008] Furthermore, an external thread is provided on a side of the rod one away from the rod two, and a portion of the rod with the external thread passes through the through hole of the flat iron.

[0009] Furthermore, the flat iron is embedded to a depth of 10 cm.

[0010] Furthermore, the fixing buckle contacts the waterproof protective layer.

[0011] Further, the steps for preventing the waterproof protective layer from falling off are:

[0012] (1) First, cut the flat iron according to the size, drill the hole according to the size of the screw, and embed the flat iron 10 cm inside the edge of the concrete slab;

[0013] (2) After the fixing buckle and the waterproof protective layer are attached, turn the butterfly nut to drive the push rod to move, so as to tighten the fixing buckle and the waterproof protective layer;

[0014] (3) Remove the anti-fall device after backfilling.

[0015] Beneficial Effects

[0016] The invention is easy to operate, improves work efficiency, improves waterproof construction quality, and the anti-falling device can be reused, thereby avoiding construction waste and saving construction costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] As shown in the figure, the present invention discloses a waterproof protective layer anti-falling device, comprising a flat iron 1, a fixing buckle 2, a push rod 3 and a butterfly nut 4. The upper end of the flat iron 1 is provided with a through hole 11, the lower end of the flat iron 1 is pre-buried in concrete 5, the upper end of the push rod 3 passes through the through hole 11 of the flat iron 1, the fixing buckle 2 is installed at the end of the push rod 3, and the butterfly nut 4 is threadedly connected with the push rod 3. The flat iron 1 is used to limit the push rod 3 so that the push rod can move along the through hole 11 of the flat iron 1, and the butterfly nut 4 is used to drive the push rod 3 to move.

[0022] In one embodiment of the present invention, the push rod 3 includes a rod 1 31, a rod 2 32 and a rod 3 33. The rod 1 31 and the rod 3 33 are parallel, the rod 2 32 connects the rod 1 31 and the rod 3 33, the rod 2 32 is perpendicular to the rod 1 31, the length of the rod 1 31 is greater than the length of the rod 3 33, the rod 3 33 is located at the lower end of the rod 1 31, and the fixing buckle 2 is installed at the end of the rod 3 33. Since the waterproof protective layer 6 is a vertical structure and is generally the outermost end, the traditional anti-falling device is not convenient for construction, and the shape design of the push rod 3 of the present invention makes it possible to pre-embed the flat iron 1 on the top of the concrete 5, and the waterproof falling layer on the side can be compressed on the top of the concrete, which is convenient for construction personnel to operate. The concrete 5 here refers to the concrete slab formed by pouring the concrete 5 rather than the concrete itself, and the waterproof protective layer 6 is located on the outside of the concrete 5.

[0023] In one embodiment of the present invention, an external thread is provided on one side of the rod 1 31 away from the rod 2 32, and the portion of the rod 1 31 with the external thread passes through the through hole 11 of the flat iron 1. The design of the external thread enables the application of pressure to the push rod 3 by rotating the butterfly nut 4.

[0024] In one embodiment of the present invention, the flat iron 1 is embedded to a depth of 10 cm.

[0025] In one embodiment of the present invention, the fixing buckle 2 is in contact with the waterproof protective layer 6 .

[0026] In one embodiment of the present invention, the steps for preventing the waterproof protective layer from falling off are as follows:

[0027] (1) First, cut the flat iron according to the size, make a hole according to the size of the screw, make a through hole 11, and embed the flat iron 1 in the concrete slab to 10 cm inside;

[0028] (2) After the fixing buckle and the waterproof protective layer are attached, turn the butterfly nut to drive the push rod to move, so as to tighten the fixing buckle and the waterproof protective layer;

[0029] (3) Remove the anti-fall device after backfilling.

[0030] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
