[0031] Example of fixing assembly for climbing frame net for construction site:

[0032] like Figure 1-3As shown, the fixing assembly of the climbing frame net 40 for construction sites includes a climbing frame net fastener 10, an extension piece 20 and a steel pipe fastener 30; one end of the climbing frame net fastener 10 is fixed with two U-shaped lock buckles 102 one above and one below, and the other end is fixed with two baffles 101 one below and one below, and the net frames of two adjacent climbing frame nets 40 are fixed in two rectangular grooves one above and one below formed by the two U-shaped lock buckles 102 and the two baffles 101; the adjustment parts 103 extending outwards of the two baffles 101 are flexibly connected to the extension piece 20 to achieve the adjustable distance between the steel pipe and the climbing frame net 40, and the end of the extension piece 20 away from the climbing frame net fastener 10 is fastened to the steel pipe fastener 30. That is, the net frame of the climbing frame net 40 is stuck between the U-shaped lock buckle 102 and the baffle 101. The climbing frame net fastener 10 fixes two adjacent climbing frame nets 40, the steel pipe fastener 30 is fixed on the steel bars of the scaffolding, and the climbing frame net fastener 10 and the steel pipe fastener 30 are connected together by the extension piece 20. Since the extension piece 20 and the climbing frame net fastener 10 are telescopically connected, the distance between the climbing frame net fastener 10 and the steel pipe fastener 30 is variable. That is, the length of the fixing assembly can be adjusted according to the distance between the climbing frame net 40 and the scaffolding steel pipe.

[0033] like Figure 4 As shown, in order to prevent the extension member 20 from shaking when connected to the climbing frame net fastener 10, the side of the adjustment portion 103 is fixedly connected with a limiting portion 104, which is used to limit the left and right movement of the extension member 20, so as to ensure that the extension member 20 is stably connected to the climbing frame net fastener 10, and further ensure the stability of the steel pipe fastener 30 relative to the climbing frame net fastener 10.

[0034] like Figure 5 As shown, in order to realize a telescopic connection between the extension piece 20 and the climbing frame net fastener 10, the telescopic connection can adopt structures such as a spiral connection and a telescopic arm. In order to make the telescopic amount of the telescopic connection controllable and convenient to accurately control the telescopic amount, the extension piece 20 includes a U-shaped frame body 201 and a plurality of positioning protrusions 202 on the U-shaped frame body 201, and a plurality of positioning holes 105 are opened on the adjustment part 103. The positioning protrusions 202 cooperate with the positioning holes 105 to realize a telescopic movable connection. When the relative distance between the extension piece 20 and the climbing frame net fastener 10 is desired to be longer, the first positioning protrusion 202 at the end is inserted into the last positioning hole 105; when the relative distance between the extension piece 20 and the climbing frame net fastener 10 is desired to be shorter, more positioning protrusions 202 are inserted into the positioning holes 105. Since the spacing of the positioning holes 105 is fixed after they are opened, the positioning protrusions 202 can be inserted into the corresponding positioning holes 105 according to the depth at which the extension member 20 is to be connected. In this way, the relative distances between the steel pipe fasteners 30 and the climbing frame net fasteners 10 are known distances, and there will be no problem of inaccurate relative distance adjustment during construction.

[0035] In order to make the connection structure between the extension piece 20 and the steel pipe fastener 30 both securely connected and easy to disassemble, a threaded hole is provided on the end of the extension piece 20 away from the climbing frame net fastener 10, and a locking nut 304 is provided on the inner side of the end where the steel pipe fastener 30 is connected to the extension piece 20, and a fastening bolt 301 passes through the locking nut 304 and the threaded hole to achieve a secure connection between the extension piece 20 and the steel pipe fastener 30. Connection through the fastening bolt 301 can also facilitate the steel pipe fastener 30 to fix steel pipes in different directions. Because the net frame of the climbing frame net 40 is generally set in a horizontal or vertical direction, but the steel pipes of the climbing frame net 40 are set in a diagonal direction in addition to horizontal and vertical directions, in order to facilitate the changeable direction of the steel pipe fixed by the steel pipe fastener 30, the fastening bolt 301 is used here for connection.

[0036] In order to ensure the tight connection between the extension piece 20 and the climbing frame net fastener 10, an inclined plate 203 is provided inside the U-shaped frame body 201, and the above-mentioned fastening bolt 301 is located on the external thread inside the extension piece 20 and fixedly connected with a conical block 302, and the conical block 302 is located above the inclined plate 203 to achieve the tight connection between the extension piece 20 and the climbing frame net fastener 10. The extension piece 20 is first inserted between the two adjustment parts 103, and then the positioning protrusion 202 enters the positioning hole 105, which causes the thickness of the U-shaped frame body 201 to be less than the distance between the adjustment parts 103, which may cause shaking. Therefore, the inclined plate 203 and the conical block 302 are provided to expand the thickness of the U-shaped frame body 201 to ensure the stable connection between the extension piece 20 and the climbing frame net fastener 10.

[0037] In order to facilitate the disassembly of the steel pipe fastener 30, the steel pipe fastener 30 includes an upper buckle cover 305 and a lower buckle cover 303. One end of the upper buckle cover 305 and the lower buckle cover 303 are hinged by a rotating shaft 307, and the other end is fastened and connected by a fastener 306. The fastener 306 can adopt a bolt structure or a latch structure. In order to facilitate the operation of the fastening bolt 301, an operation port is opened on the upper buckle cover 305, which is convenient for a wrench to go deep into the bolt to tighten it.

[0038] like Figure 6 As shown, since the width of the mesh frame of the climbing frame net 40 is not unique, in order to facilitate the climbing frame net fastener 10 to clamp mesh frames of different widths. It also includes a top tightening member 106, which includes a U-shaped frame 1061 and a pressure plate 1062 connected to the front end of the U-shaped frame 1061. The U-shaped frame 1061 is clamped on the end of the climbing frame net fastener 10 where the baffle 101 is fixed. The pressure plate 1062 is parallel to the baffle 101. The tail end of the fastening bolt 301 is used to resist the rear end of the U-shaped frame 1061 to achieve the screwing of the fastening bolt 301 to push the top tightening member 106. In this way, the distance between the U-shaped lock buckle 102 and the pressure plate 1062 is the width of the mesh frame that can be fixed. At the same time, it also avoids the large gap between the U-shaped lock buckle 102 and the baffle 101, which affects the overall connection firmness.

[0039] Except for the top fastener 106, the other parts of the climbing frame net fastener 10 are integrally bent and chamfered at the bend. Integral molding is conducive to improving overall rigidity and reducing stress concentration. In this embodiment, the climbing frame net 40 can be fixed to the outside of the steel pipe when the steel pipe is in a horizontal, vertical, or even inclined state.

[0040] The above is only a preferred embodiment of the present invention and does not constitute any limitation to the present invention. Any simple modification, change and equivalent structural change made to the above embodiments according to the technical essence of the present invention shall still fall within the protection scope of the technical solution of the present invention.
