[0002] Due to the need for hoisting in steel structure construction, no external scaffolding is set up around the building during construction, so it is easy for high-altitude falling accidents to occur on the floor edges. Due to the particularity of the floor decking, the standardized edge protection railing columns cannot be installed on the ground before the concrete of the floor decking is poured. Therefore, the setting of floor safety railings is a difficult point. Generally, steel structures are used for auxiliary fixing. However, the size of this kind of steel structure workpiece needs to be adjusted, so it needs to be clamped and positioned multiple times during the processing, resulting in low efficiency. For this reason, we propose a steel structure standardized edge protection base, a tooling fixture for the base, and an edge protection method to solve the above problems. Summary of the invention

[0014] A method for edge protection of a steel structure standardized edge protection base:

[0015] S1. When in use, the column foot position of the standardized edge guardrail is arranged at the edge of the floor decking plate, and the side wall of the pier is perpendicular to the edge of the floor, so that the force is more reliable before pouring concrete. The support foot is welded to the steel plate at the bottom of the floor decking plate, and the lower mouth of the top of the pier is welded with a pre-embedded fixing nut, which is used in conjunction with a flat washer and a bolt;

[0016] S2. After the main body of the base is welded, it is connected to the standardized guardrail column through bolts and flat washers, and then the column is connected to the standardized guardrail to achieve an overall protective effect. When the exterior wall is built later, the guardrail can be gradually dismantled. It can be easily dismantled by unscrewing the bolts in the opposite direction.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention uses the buffer sleeve to deform during the clamping process, increasing the contact area to reduce the occurrence of indentations. After the base body is removed, the counterweight rod swings to enable the reset shaft to pull the buffer sleeve, which can shake off the debris remaining on the surface, thereby reducing the adhesion of debris under the action of the cutting fluid.

[0019] 2. The present invention can adjust the milling and grinding at different positions through the rotating disk, and under the cooperation of the clamping mechanism and the positioning mechanism, the base body can be clamped and positioned, and the inclination angle of the base body can be adjusted during welding or milling and grinding, which can improve the processing efficiency of the equipment;

[0020] 3. The present invention can change the air pressure inside the expansion chamber through the air supply of external equipment, so that the air pressure pad is pressed against the side walls of the piers on both sides to assist in clamping and positioning. In the subsequent replacement of parts, the internal air pressure changes, which can cause the surface of the air pressure pad to deform, and can quickly shake off the debris remaining on its surface and edge, thereby reducing the residual situation;

[0021] 4. The present invention can drive the clamping frame to flip by means of a control motor, can be pressed against the inner wall of the pier side wall, can cooperate with the air pressure pad for clamping, can clamp both ends of the pier side wall, and prevent the deformation of the base body under the clamping force caused by unilateral clamping;

[0022] 5. After the base body is welded, the present invention is connected to the standardized guardrail column by means of bolts and flat washers, and then the column is connected to the standardized guardrail to achieve an overall protective effect. Compared with the limit of bolts and nuts, there is no need to limit the nuts during installation, which improves the on-site installation efficiency. When the exterior wall is built in the later stage, the guardrail can be gradually disassembled. It can be easily disassembled by unscrewing the bolts in the opposite direction.

When the guardrail is supported by the base body 5, the base body 5 is simple and practical in structure, low in cost, good in effect, firm and reliable, and can solve the problem that the edge protection railing column cannot be installed on the ground.

[0035] Example 2: Please refer to Figure 3-9The present invention provides a technical solution: a fixture for a steel structure standardized edge protection base, comprising a clamping seat 1, a rotating disk 11 is rotatably provided on the top of the clamping seat 1, a scale line is provided on the rotating disk 11, a limit platform 2 is installed on the top of the rotating disk 11, the limit platform 2 is used for auxiliary support, and a plurality of positioning mechanisms 3 and a clamping mechanism 4 are provided on the top of the limit platform 2;

[0036] The positioning mechanism 3 is symmetrically arranged at the top of the limit platform 2, and the clamping mechanism 4 is installed at the middle end of the limit platform 2.

During the clamping process, the milling and grinding at different positions can be adjusted with the help of the rotating disk 11, and the base body 5 can be clamped and positioned under the cooperation of the clamping mechanism 4 and the positioning mechanism 3, and the inclination angle of the base body 5 can be adjusted during welding or milling and grinding, which is convenient for grinding and cleaning the connection between the pier side wall 54 and the pier top surface 57, and also for cleaning the outside of the embedded fixing nut 56, reducing the sharp protrusions at the welding point and reducing the safety hazards of the operator during use.

[0037] like Figure 3 As shown, friction will occur on the surface of the buffer plate 21 due to friction during the clamping process. A plurality of slide grooves are provided on the top of the limit platform 2. A pair of buffer plates 21 are installed on the top of the limit platform 2. The buffer plates 21 are symmetrical on both sides of the clamping mechanism 4. A wear-resistant plate is provided on the top of the buffer plate 21. The buffer plate 21 can be against the bottom of the base body 5 for auxiliary support, and the wear-resistant plate can extend the service life of the buffer plate 21.

[0038] like Figure 4 As shown, since the base body 5 is easily clamped in an unstable state during the limiting process, the positioning mechanism 3 includes a transmission plate 31, a limiting slide plate 32 and a lifting plate 33. The transmission plate 31 is movably clamped inside the slide groove, a clamping groove is provided on the side wall of the transmission plate 31, and the limiting slide plate 32 is movably clamped inside the clamping groove. The limiting slide plate 32 is "L" shaped, and a lifting plate 33 is movably clamped on the upper end of the limiting slide plate 32, and a support plate 34 is installed on the lifting plate 33;

[0039] An air inlet hole is provided on the side wall of the support plate 34, and the air inlet hole is connected to an external air pressure device. A pair of air pressure pads 35 are installed on the support plate 34. An expansion chamber 351 is provided inside the air pressure pad 35, and the expansion chamber 351 is communicated with the air inlet hole. The air pressure pad 35 is used to abut against the two ends of the base body 5. As the air is supplied by the external equipment, the air pressure inside the expansion chamber 351 can change, so that the air pressure pad 35 abuts against the side walls 54 of the pier on both sides to assist in clamping and positioning. In the subsequent replacement of parts, the internal air pressure changes, which can cause the surface of the air pressure pad 35 to deform, and can quickly shake off the debris remaining on its surface and edge to reduce the residue.

[0040] like Figure 5 As shown, in order to prevent the situation of deviation during the clamping process, a pair of movable plug rods are installed on the top of the lifting plate 33, and a movable plate 36 is installed on one end of the movable plug rods. The movable plate 36 is rotatably provided with a rotating shaft 371 on the side away from the support plate 34, and a transmission disk 37 is installed on one end of the rotating shaft 371. The transmission disk 37 is symmetrically arranged, and a plurality of elastic pressure rods are inserted on the outer wall of the transmission disk 37. A telescopic shaft 361 is provided on the inner side of the transmission disk 37, and the telescopic shaft 361 is installed on the movable plate 36. The telescopic shaft 361 is used to adjust the position of the transmission disk 37 on the rotating shaft 371. A movable plug bracket is inserted at the bottom of the movable plate 36 38, the movable bracket 38 is located between the transmission disks 37. During the clamping process, when the lifting plate 33 abuts against the top surface 57 of the pier, auxiliary positioning can be performed with the help of the elastic pressure rod on the surface of the transmission disk 37 to prevent deviation during the auxiliary positioning process, and when it is necessary to grind the edge of the embedded fixing nut 56, the support foot 55 can be clamped between the transmission disks 37, and the telescopic shaft 361 can control the spacing of the transmission disks 37, thereby limiting the support foot 55, and the movable bracket 38 can play a role of support and limitation, and the clamping position can be changed according to different processing needs.

[0041] like Figure 7 As shown, during the clamping process, the base body 5 needs to be tilted and rotated to facilitate subsequent grinding and milling. The clamping mechanism 4 includes a positioning seat 41, a movable shaft 42 and an adjusting shaft 43.

Telescopic rods 44 are provided at both ends of the adjusting shaft 43. The rotation of the adjusting shaft 43 is used to adjust the clamping angle, and the lifting plate 33 on the positioning mechanism 3 is active, so that the base body 5 can be tilted and rotated to one side.

[0042] like Figure 8 As shown, in order to ensure the stability of clamping, a control motor 45 is installed inside the telescopic rod 44, an arc-shaped groove is opened on the telescopic rod 44, and a transmission rod 461 is movably provided inside the arc-shaped groove, one end of the transmission rod 461 is connected to the output end of the control motor 45, a clamping frame 46 is installed at one end of the transmission rod 461, and a docking shaft 47 is installed at one end of the clamping frame 46, and the docking shaft 47 is used for auxiliary support clamping, and can drive the clamping frame 46 to flip with the help of the control motor 45, can be against the inner wall of the pier side wall 54, can cooperate with the air pressure pad 35 for clamping, and can clamp both ends of the pier side wall 54 to prevent the deformation of the base body 5 under the clamping force due to unilateral clamping.

[0043] like Fig. 9As shown, since bending or indentation may easily occur under the action of the holding force during the clamping process, a buffer sleeve 471 is installed on the docking shaft 47. The buffer sleeve 471 is elastic and a reset shaft 48 is installed on the surface. An air pressure chamber is provided inside the buffer sleeve 471, and the reset shaft 48 is in a "V" shape. A counterweight rod 481 is installed at one end of the reset shaft 48, and metal partitions 462 are installed on both sides of the clamping frame 46. The reset shaft 48 is inserted between the metal partitions 462 and can be deformed during the clamping process under the action of the buffer sleeve 471 to increase the contact area, thereby reducing the occurrence of indentations. After removing the base body 5, the swing of the counterweight rod 481 can cause the reset shaft 48 to pull the buffer sleeve 471, so as to shake off the debris remaining on the surface and reduce the adhesion of debris under the action of the cutting fluid.
