Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Example 1:

referring to the attached figure 1, the building construction protective guard comprises two bases 1, wherein two upright posts 2 are inserted into the two bases 1 through threads respectively. The side wall of any upright post 2 close to the base 1 is uniformly provided with a plurality of reinforcing ribs 3 on the circumference, the number of the reinforcing ribs 3 is four, each reinforcing rib 3 is fixed on the upright post 2, and one side of each reinforcing rib 3 close to the base 1 is tightly propped against the base 1. Two beams 4 are arranged between the two upright posts 2 at intervals, and the two beams 4 are an upper beam 41 and a lower beam 42 respectively. The two ends of the upper beam 41 are respectively fixed with a sliding sleeve 5, the two sliding sleeves 5 are respectively sleeved on the upright posts 2 and are in sliding fit with the upright posts 2, the two upright posts 2 are respectively provided with a fixing part, the fixing parts are fixing bolts 6, and the two fixing bolts 6 respectively penetrate through the two sliding sleeves 5 in a threaded manner and are tightly abutted against the corresponding upright posts 2. The two ends of the lower beam 42 are respectively fixed on the two upright posts 2, and the fixed positions of the two ends are close to the upper side of the reinforcing rib 3. A folding baffle 7 is arranged between the upper beam 41 and the lower beam 42.

When the guardrail is used, the fixing bolt 6 is loosened, the upper beam 41 is moved upwards, the folding baffle 7 is stretched upwards along with the upper beam 41, the height of the guardrail is lifted upwards until the height is adjusted to the required height, and the fixing bolt 6 is fastened; conversely, the upper beam 41 is moved downward, and the folding flap 7 is downwardly condensed along with the lower beam 42, so that the height of the guard rail is lowered downward.

Referring to fig. 1-2, the folding baffle 7 includes two folding rods 8 arranged at left and right intervals, two ends of the folding rods 8 are respectively hinged with the two cross beams 4, the folding rods 8 are composed of a plurality of sequentially hinged branch rods 81, each branch rod 81 on the two folding rods 8 is arranged in one-to-one correspondence according to the height of the branch rod, and a rotating shaft 82 is erected between the two branch rods 81 which are arbitrarily arranged in correspondence. Any rotating shaft 82 is sleeved with a sub-plate 83, the rotating shaft 82 penetrates through the sub-plate 83 along the length direction of the sub-plate 83 and forms a rotating fit with the sub-plate 83, and the contact surface of any sub-plate 83 and the corresponding rotating shaft 82 is arranged in a rough manner.

When the upper beam 41 is adjusted upwards, the angle between any two adjacent branch rods 81 is gradually increased, so that the two folding rods 8 are synchronously stretched, and each branch plate 83 is correspondingly stretched; when the two folding rods 8 are not completely stretched and a large gap exists between two adjacent sub-plates 83, the two sub-plates 83 can be respectively turned over, so that the positions of the two sub-plates 83 close to each other are mutually abutted, and the flying of dust in the protective guard is reduced.

Referring to fig. 1 and 3, a hinge seat 9 is arranged at the hinge joint of any two adjacent branch rods 81 on any folding rod 8, and the hinge seat 9 comprises two hinge plates 91 arranged in parallel at intervals. Two hinge shafts 92 are fixed between the two hinge plates 91 in parallel, the two hinge shafts 92 are arranged at intervals along the vertical direction, and any hinge shaft 92 vertically penetrates through the two hinge plates 91 and is rotatably connected to the hinge plates 91. A limiting plate 93 is further arranged between the two hinge plates 91 of any hinge seat 9, the limiting plate 93 is vertically arranged between the two corresponding hinge plates 91 and is fixed with the two hinge plates 91, a U-shaped notch 94 for enabling the two adjacent branch rods 81 to turn is defined between the limiting plate 93 and the two corresponding hinge plates 91, and the opening directions of the U-shaped notches 94 of any two adjacent hinge seats 9 on the same folding rod 8 are opposite. A reflector 10 is fixed to a side of any one of the limit plates 93 away from the hinge shaft 92.

The movable range of the two branch rods 81 on any hinged seat 9 is limited in the U-shaped groove 94, so that the phenomenon that the moving directions of all hinged parts are disordered and are partially blocked when the folding rod 8 is folded is avoided. Meanwhile, any one of the reflective plates 10 faces one side of the folding baffle 7, and can attract the attention of passing vehicles at night.

The working principle of the embodiment is as follows: when in use, the fixing bolt 6 is loosened to move the upper beam 41 upwards; along with the rising of the upper beam 41, the angles of any two adjacent branch rods 81 on any upright post 2 are gradually increased, the two folding rods 8 are synchronously stretched, so that the folding baffle 7 is stretched, the branch plates 83 can be respectively turned over at the moment, the positions of any two adjacent branch plates 83 close to each other are mutually abutted, and the gaps among the branch plates 83 are reduced; when the two folding rods 8 are completely stretched, the branch rods 81 are positioned on the same straight line, and the branch plates 83 form a vertical plate surface together; conversely, the upper beam 41 is moved downwards to make the two folding rods 8 and thus the folding baffles 7 to be folded. Through this kind of mode, conveniently adjust the height of rail guard according to the construction occasion of difference, improve the convenience of using.

Example 2:

referring to fig. 4, a building construction protective fence is different from embodiment 1 in that a plurality of columns 2 are provided, and the columns 2 are arranged in parallel at intervals. A plurality of upper beams 41 and a plurality of lower beams 42 are respectively arranged, and each upper beam 41 and each lower beam 42 are correspondingly arranged between any two adjacent upright posts 2.
