Detailed Embodiment

[0025] The present utility model will be further described below in conjunction with the description of the drawings and embodiments. The embodiments of the present utility model include but are not limited to the following embodiments.

[0026] First Embodiment:

[0027] As Figures 1-4As shown in the figure, the warning device for edge protection in building construction provided by the present utility model includes a warning mechanism 100 and a blocking mechanism 300. The warning mechanism 100 means that when a staff member inadvertently approaches the edge position of a building, such as a window or other positions, the warning mechanism 100 will emit sounds and other signals to alert the staff. The function of the blocking mechanism 300 is to temporarily seal the edge opening to prevent the staff from falling. Specifically, the blocking mechanism 300 includes a railing 302, and the railing 302 is installed on the door and window 400. The warning mechanism 100 includes a thin steel wire 101 and a control component. The control component is installed on both sides of the door and window 400. The two ends of the thin steel wire 101 are respectively installed on the left and right control components. The control component includes a housing 102. Inside the housing 102, there are two steel sheets 104. The steel sheets 104 are arc-shaped. There is a bolt 105 between the two steel sheets 104. One side of the housing 102 is provided with a cover plate 103. The cover plate 103 is provided with a sliding groove. The bolt 105 can slide in the sliding groove. One end of the bolt 105 is pointed and the middle part is convex. The convex part is larger than the distance between the upper and lower steel sheets 104. The other end is provided with a tail end 108. The thin steel wire 101 is elastic and bent into a "Ω" shape. The tail end 108 has a cavity. One side of the cavity is open. The upper and lower side walls of the cavity limit and support the thin steel wire 101 to keep it in the horizontal plane. The two ends of the thin steel wire 101 are inserted on the inner wall of the cavity. On the inner wall of the housing 102 opposite to the bolt 105, there is a bell. When a staff member inadvertently approaches the edge position and touches the thin steel wire 101, the thin steel wire 101 is squeezed and deformed. After the arched thin steel wire 101 is subjected to pressure, a thrust is generated at the arch feet, that is, the two ends of the thin steel wire 101, acting on the outside. The two ends of the thin steel wire 101 push the bolt 105 to increase the extrusion force on the steel sheet 104. The anti-deformation ability of the steel sheet 104 is related to factors such as its own material and thickness and can be adjusted. When the convex position of the bolt 105 passes through the steel sheet 104 and hits the bell at its front end, the bell makes a sound to remind the staff to pay attention. After the device triggers the alarm, the bolt 105 can be pulled back to its original position and can be used continuously.

[0028] By setting up a control component, etc., the warning effect on the staff is achieved, ensuring the safety of the staff. Compared with the existing method of triggering the alarm through a toothed plate, this device uses the thin steel wire 101 as the medium for triggering the alarm, with a small volume, easy to install, and having a certain elasticity itself, making the trigger of the alarm more sensitive.

[0029] Second Embodiment:

[0030] As Figures 2-5As shown, a clamping mechanism 200 is also provided on one side of the blocking mechanism 300. The clamping mechanism 200 includes a vertical plate 201. A hole is provided on the vertical plate 201. The hole diameter is equivalent to the diameter of the slide rod 203. The slide rod 203 penetrates into the hole. A clamping plate 202 is provided on the inner side of the vertical plate 201. One end of the slide rod 203 is installed on the clamping plate 202. A first spring 204 is provided between the vertical plate 201 and the clamping plate 202. The first spring 204 is located on the slide rod 203. The vertical plate 201 is a frame. The clamping plate 202 is clamped on the wall of the door and window openings. Figure 5 , pull the slide bar 203 outward, the slide bar 203 drives the clamping plate 202 to move, and the clamping plate 202 compresses the first spring 204. Then move the vertical plate 201 to the wall of the door and window openings and release the slide bar 203. The clamping plate 202 moves inward under the elastic force of the first spring 204 and is clamped on the wall surface, thereby fixing the entire clamping mechanism 200 on the wall.

[0031] The installation effect of the clamping mechanism 200 is achieved by providing the clamping plate 202 and the first spring 204. The position of the clamping plate 202 can be changed, and the distance between the two clamping plates 202 can be adjusted to adapt to door and window opening walls of different thicknesses.

[0032] Third embodiment:

[0033] like Figure 4 As shown, a threaded rod 107 and a slide rail are further provided in the housing 102. The threaded rod 107 and the slide rail pass through the steel sheet 104. The steel sheet 104 and the threaded rod 107 are threadedly connected. The steel sheet 104 is slidably connected to the slide rail. The slide rail guides the steel sheet 104. The threads at both ends of the threaded rod 107 are in opposite directions. A handwheel 106 is provided at one end of the threaded rod 107. Turning the handwheel 106 drives the threaded rod 107 to rotate. The threaded rod 107 pushes the two ends of the steel sheet 104 to move toward or in the opposite direction, thereby changing the bending curvature of the steel sheet 104 and the distance between the two steel sheets 104.

[0034] The threaded rod 107 is provided to adjust the spacing of the steel sheets 104 . The larger the curvature of the steel sheets 104 and the smaller the spacing, the greater the blocking effect on the latch 105 . Therefore, the sensitivity of the early warning device can be adjusted according to the actual construction site environment.

[0035] Fourth embodiment:

[0036] like Figure 2 , Figure 6As shown, the railing 302 is tubular, with openings at both ends and sealed in the middle. Sleeves 301 are slidably provided at both ends of the railing 302. A second spring 303 is provided inside the railing 302 and the sleeves 301. Both ends of the second spring 303 are fixed to the inner walls of the railing 302 and the sleeves 301. A connecting cylinder 205 is provided outside the vertical plate 201, and the sleeve 301 is installed inside the connecting cylinder 205. During use, the two sleeves 301 are squeezed inward, and then the sleeves 301 are installed into the connecting cylinder 205. When the sleeves 301 are released, under the thrust of the second spring 303 on the sleeves 301, it is stably installed in the connecting cylinder 205.

[0037] By setting the second spring 303, the overall length of the railing 302 and the sleeves 301 can be adjusted, which is convenient for the staff to install them into door and window openings with different widths. At the same time, it is convenient for disassembly, installation and recycling.

[0038] Fifth Embodiment:

[0039] As Figure 5 shown, there is a threaded section on the sliding rod 203, and a nut 206 is provided on the threaded section. The nut 206 is located outside the vertical plate 201, and the nut 206 is stuck outside the vertical plate 201 to restrict the clamping plate 202 from moving inward. During use, the clamping plate 202 can be first placed on both sides of the wall of the door and window opening, and then the nut 206 is rotated to release the restraint on the sliding rod 203, that is, the sliding of the sliding rod 203 can be made controllable by setting the nut 206.

[0040] Sixth Embodiment:

[0041] A rubber pad is provided inside the clamping plate 202, and the rubber pad can increase the contact with the wall and enhance the connection stability.

[0042] Working Principle: When the staff inadvertently approaches the edge position and touches the thin steel wire 101, the thin steel wire 101 is squeezed and deformed. After the arched thin steel wire 101 is subjected to pressure, a thrust is generated on the outside at the arch feet, that is, both ends of the thin steel wire 101. The two ends of the thin steel wire 101 push the bolt 105 to increase the extrusion force on the steel sheet 104. The anti-deformation ability of the steel sheet 104 is related to factors such as its own material and thickness and can be adjusted. When the convex position of the bolt 105 passes through the steel sheet 104, it hits the bell at its front end, and the bell makes a sound to remind the staff.

[0043] The above embodiments are only one of the preferred embodiments of the present invention and should not be used to limit the protection scope of the present invention. Any meaningless changes or touch-ups made on the main design concept and spirit of the present invention, as long as the technical problems solved are still the same as those of the present invention, should be included in the protection scope of the present invention.
