Technical Field
[0001] This utility model relates to the field of highway bridge construction technology, and in particular to a pre-construction safety protection device for cap beam construction. Background Technology
[0002] The pre-construction safety protection device for cap beam construction is used when there is no safety protection during the installation of clamps and the erection of crossbeams and distribution beams before cap beam construction. It mainly solves the problem that when setting up a working platform and installing clamps, crossbeams and distribution beams before cap beam construction, there is no reliable hanging position or other protection due to the structural characteristics of the column pier. Therefore, a pre-construction safety protection device that can be installed on the column pier is needed to protect construction personnel. Utility Model Content

[0006] The steel plate connector has a high-strength bolt connection hole, which is connected to the steel pipe tie rod by two M10 high-strength bolts.
[0007] The inverted conical steel pipe frame is an inverted cone shape that is wider at the top and narrower at the bottom. The coverage area of the top surface of the inverted conical steel pipe frame is determined by the height of the pier column and is not less than the fall radius of high-altitude operations.
[0008] The steel pipe tie rod, the arc-shaped round steel pipe, and the vertical connecting steel pipe are all the same size.
[0009] The top surface width corresponding to the length of the steel pipe tie rod is consistent with the fall radius.
[0010] Each of the vertical connecting steel pipes has an insertion hole; the two ends and the middle position of the arc-shaped round steel pipe are respectively connected to the top of the three vertical connecting steel pipes through the insertion hole, and the bottom of the three vertical connecting steel pipes are respectively connected to the three steel pipe diagonal tie rods through the insertion hole.
[0011] The fall protection safety net is laid horizontally along the cap beam and is matched with the fall protection safety net hook.
[0012] This utility model has the following advantages compared with the prior art:
[0013] 1. This utility model effectively improves the safety of construction personnel during the construction of the cap beam by setting up clamps and inverted conical steel pipe frames fixed on the clamps before the construction of the cap beam, and by hanging anti-fall safety nets.

Detailed Implementation
[0019] like Figures 1-2 As shown, a pre-construction safety protection device for cap beam construction includes a pair of clamps 1 and an inverted conical steel pipe frame 2 symmetrically fixed to the pair of clamps 1; each clamp 1 has three steel plate connectors 3 welded equally on its half-side clamp plate; the inverted conical steel pipe frame 2 is formed by inserting three steel pipe diagonal braces 5, one arc-shaped round steel pipe 6, and three vertical connecting steel pipes 7; the three steel pipe diagonal braces 5 are connected one-to-one with the steel plate connectors 3; anti-fall safety net hooks 9 are symmetrically installed on the clamps 1 and the arc-shaped round steel pipe 6, and anti-fall safety nets 10 are laid through the anti-fall safety net hooks 9.
[0020] Among them: the clamp 1 is the same size as the column diameter of the column pier, with clearance fit.
[0021] The steel plate connector 3 has a high-strength bolt connection hole 4, which is connected to the steel pipe tie rod 5 by two M10 high-strength bolts.
[0022] The inverted conical steel pipe frame 2 is an inverted cone shape that is wider at the top and narrower at the bottom. The coverage area of the top surface of the inverted conical steel pipe frame 2 is determined by the height of the pier column and is not less than the fall radius of high-altitude operations.
[0023] The steel pipe tie rod 5, the arc-shaped round steel pipe 6, and the vertical connecting steel pipe 7 have the same dimensions, and Φ32*25 seamless pipe is generally selected.
[0024] The top surface width corresponding to the length of the steel pipe tie rod 5 is consistent with the fall radius.
[0025] Each vertical connecting steel pipe 7 has a splice hole 8; the two ends and the middle position of the arc-shaped round steel pipe 6 are respectively connected to the top of the three vertical connecting steel pipes 7 through the splice holes 8, and the bottom of the three vertical connecting steel pipes 7 are respectively connected to the three steel pipe diagonal tie rods 5 through the splice holes 8.
[0026] The fall protection safety net 10 is laid horizontally along the cap beam and is matched with the fall protection safety net hook 9.
[0027] The device described in this utility model is a composite component, so each component needs to be manufactured separately.
[0028] In use, first determine the installation position of the clamp 1 and the installation angle of the steel pipe tie rod 5 according to the pier diameter, pier spacing and cap beam length. The installation height of the clamp 1 should be controlled within 2 meters to avoid working at height. Then, use M10 high-strength bolts to fix the steel pipe tie rod 5 through the high-strength bolt connection holes 4 on the steel plate connector 3. Next, insert the vertical connecting steel pipe 7 into the steel pipe tie rod 5, and after the connection is tight, insert and install the arc-shaped round steel pipe 6 to complete the installation of the inverted conical steel pipe frame 2. Finally, hang the fall protection safety net 10 horizontally along the cap beam according to the fall protection safety net hooks 9 on the clamp 1 and the inverted conical steel pipe frame 2.
