Fence for engineering construction

Abstract

The fence for engineering construction comprises a base and a baffle, the base is a cuboid, a triangular stand column I is vertically fixed to the upper portion of one end of the base, a triangular stand column II is vertically fixed to the upper portion of the other end of the base, and a rotating shaft rod parallel to the base is installed between the top of the triangular stand column I and the top of the triangular stand column II. A frame is fixedly installed on the shaft rod between the triangular stand column I and the triangular stand column II, a baffle is fixed in the frame, and a manual adjusting screw rod is installed between the bottom of the frame and one side of the base. The fence for engineering construction is simple in structure and reasonable in design, the wind resistance is reduced by adjusting the inclination of the fence, then the stability of the whole fence in the wind resistance is improved, and the fence is flexible and changeable and is slightly influenced by the natural wind direction. A constructor can adjust the inclined wind direction of the fence according to the wind direction, and the defect that wind resistance cannot be achieved due to the fact that a supporting structure cannot be adjusted due to wind direction change after a traditional fence is fixed is overcome.

Description

TECHNICAL FIELD

[0001] The utility model belongs to the fence, in particular to a kind of fence for engineering construction. BACKGROUND

[0002] Warning fence generally refers to the occasion in construction, maintenance or other needs warning, to isolate dangerous area or mark the fence or isolation facilities of specific area. These fences usually have eye-catching color and sign, to attract attention and remind people to pay attention to the surrounding danger. They can be seen frequently in construction site, road construction site, traffic accident site and other places. Using warning fence can effectively protect people's safety, and avoid accidents.

[0003] The baffle on the traditional fence is basically perpendicular to the ground, and the resistance to wind is large in some areas with large wind force. The traditional construction fence may be blown down by the wind, causing safety accidents. Chinese patent publication No. CN222350435 U, patent name is a construction engineering construction warning fence. Construction personnel increase support structure behind the fence to improve the wind resistance of the fence. However, the main body of the fence is still perpendicular to the ground, and the wind resistance is large. Secondly, when the wind direction changes, the support structure loses the resistance to wind. Otherwise, only the direction of the fence can be changed. Since the fence is fixed on the ground, it is obviously very inconvenient to adjust the fence. The wind direction is not fixed, so the practicality is greatly limited. UTILITY MODEL CONTENTS

[0006] As a further improvement of the utility model, hand-operated adjusting screw is placed in the middle of the side of base, a row of transverse pin holes is uniformly distributed on both sides of base, pin hole ear is fixed on the side of frame corresponding to transverse pin hole, lock pin is inserted between transverse pin hole and pin hole ear.

[0007] As a further improvement of the utility model, more than one symmetric connection lock hole is provided on triangular column I and triangular column II, and more than one fixed pin hole is provided on both sides of base.

[0008] As further improvement of the utility model, the end of the manual adjusting screw rod is provided with a bearing, two rotating rods I are fixed on the bearing and rotatably connected with rotating rod seats I on the frame; a nut is connected with the screw opening of the manual adjusting screw rod, and two rotating rods II are fixed on the nut and rotatably connected with rotating rod seats II fixed on the base.

[0009] The utility model discloses an enclosure for engineering construction, simple structure, reasonable in design, reduce the resistance to wind through the inclination of the enclosure, and further promote the stability in the wind resistance, flexible and changeable, less affected by the natural wind direction. Construction personnel can adjust the inclination of the enclosure according to the wind direction, solve the drawback that the traditional enclosure cannot adjust the supporting structure after being fixed due to the change of wind direction, and cannot resist the wind, convenient and fast, improve the practicality of the enclosure.

[0012] The following will be combined with the drawings of the utility model Figure 1 and the drawings of the utility model Figure 2 Further illustrate the utility model of an enclosure for engineering construction.

[0013] Embodiment 1

[0014] The utility model discloses an enclosure for engineering construction, including base 1 and baffle 2, the base 1 is cuboid, and the upper portion of one end is fixed with triangular column I 3, and the upper portion of the other end is fixed with triangular column II 4, and the top between triangular column I 3 and triangular column II 4 is installed with rotating axle rod 5 parallel to base 1, the axle rod 5 between triangular column I 3 and triangular column II 4 is fixedly installed with frame 6, and baffle 2 is fixed in frame 6, and manual adjusting screw rod 7 is installed between the bottom of frame 6 and one side of base 1.

[0015] Embodiment 2

[0016] The utility model discloses an enclosure for engineering construction, including base 1 and baffle 2, the base 1 is cuboid, and the upper portion of one end is fixed with triangular column I 3, and the upper portion of the other end is fixed with triangular column II 4, and the top between triangular column I 3 and triangular column II 4 is installed with rotating axle rod 5 parallel to base 1, the axle rod 5 between triangular column I 3 and triangular column II 4 is fixedly installed with frame 6, and baffle 2 is fixed in frame 6, and manual adjusting screw rod 7 is installed between the bottom of frame 6 and one side of base 1.
