[0002] Construction is the production activity in the implementation stage of project construction, which is the construction process of various buildings. It can also be said to be the process of turning the various lines on the design drawings into physical objects at the designated location. It includes foundation engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. During the process of engineering construction, protective fences will be used. The protective fences can provide good protection for the construction section, and at the same time can play a certain warning role for pedestrians, facilitating the normal progress of construction. Usually, the protective fences seen need to be assembled together when in use. However, the common assembly structures mostly use the way of screw fixation. After long - term use, this way will loosen, thus causing some problems of structural disconnection. For this reason, this application proposes an anti - detachment structure for a protective fence in engineering construction. Content of the Utility Model

[0003] To solve the problems raised in the above - mentioned background art, the utility model provides the following technical solution: An anti - detachment structure for a protective fence in engineering construction, including a bottom plate and a top plate.

First slots are opened at both ends of the bottom of the top plate. The tops of the two support rods are respectively inserted into the two first slots at the top of the top plate. A plurality of grooves are evenly opened at the top of the top plate. Through - holes smaller than their diameters are opened at the bottom of each groove. A blocking rod is movably inserted into each corresponding groove and through - hole. A baffle larger than its diameter is fixedly installed at the top of each blocking rod. Second slots with the same number as the grooves are evenly opened at the top of the bottom plate. The bottom ends of each blocking rod are respectively inserted into the corresponding second slots. Through - holes are opened on the side surfaces of the bottom ends of each blocking rod. An insertion hole penetrating through each second slot is opened at one end of the bottom plate. A screw rod is movably inserted into the insertion hole. The screw rod sequentially penetrates through the through - holes at the bottom ends of a plurality of blocking rods.

[0004] Further, second screw holes are opened on the side surfaces of the tops of the two support rods. First screw holes communicated with the corresponding first slots are opened on both sides of the top plate. Bolts are threadedly inserted into the corresponding first screw holes and second screw holes.

[0005] Further, a hexagonal groove is opened at one open end of the insertion hole. A hexagonal nut adapted to its size is arranged in the hexagonal groove. One end of the screw rod penetrating through a plurality of through - holes is threadedly inserted into the hexagonal nut.

[0006] Further, when the screw rod is inserted into the through - hole at the bottom end of the blocking rod, the bottom of the baffle at the top of the blocking rod fits against the bottom of the inner wall of the corresponding groove.

[0007] Furthermore, the height of the fixing member on the left side at the top of the bottom plate is less than the height of the fixing member on the right side at the top thereof, and the height of the support rod connected to the left fixing member is greater than the height of the support rod connected to the right fixing member. The tops of the two support rods are at the same horizontal height. When the two support rods are in a horizontal state, the support rod on the right presses on the support rod on the left.

[0008] Furthermore, stoppers are fixedly installed at both ends of the top of the bottom plate. When the two support rods are in a vertical state, the side walls of the two support rods are respectively in contact with the two stoppers.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] By fixing the position of the bottom end of each stop rod through a screw, the baffle at the top of each stop rod applies pressure to the top plate, so that the top plate can be stably connected to the tops of the two support rods. As long as the screw does not disengage from the jack, the baffle at the top of the stop rod can continuously apply pressure to the top plate, thereby avoiding the disconnection between structures.

Detailed implementation manner

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Given by Figure 1-8 The present invention includes a bottom plate 1 and a top plate 5. Fixing members 2 are fixedly installed at both ends of the top of the bottom plate 1. Support rods 3 are rotatably connected to both fixing members 2. First slots 6 are opened at both ends of the bottom of the top plate 5. The tops of the two support rods 3 are respectively inserted into the two first slots 6 at the top of the top plate 5. A plurality of grooves 10 are evenly opened at the top of the top plate 5. Through holes 11 smaller than their diameters are opened at the bottom of each groove 10. A stop rod 12 is movably inserted into each corresponding groove 10 and through hole 11. A baffle larger than its diameter is fixedly installed at the top of each stop rod 12. Second slots 14 with the same number as the grooves 10 are evenly opened at the top of the bottom plate 1. The bottom ends of each stop rod 12 are respectively inserted into the corresponding second slots 14. Through holes 13 are opened on the side surfaces of the bottom ends of each stop rod 12. An insertion hole 15 penetrating through each second slot 14 is opened at one end of the bottom plate 1. A screw rod 18 is movably inserted into the insertion hole 15. The screw rod 18 sequentially passes through and is inserted into the through holes 13 at the bottom ends of a plurality of stop rods 12. During installation, first rotate the two support rods 3 to make them in a vertical state, then install the top plate 5 at the tops of the two support rods 3, then sequentially insert a plurality of stop rods 12 through the through holes 11 on the top plate 5 and insert them into the second slots 14 on the bottom plate 1, and finally insert the screw rod 18 into the insertion hole 15 at one end of the bottom plate 1 and pass through the through holes 13 at the bottom ends of each stop rod 12.

[0023] At the same time, second screw holes 8 are opened on the side surfaces of the tops of the two support rods 3. First screw holes 7 communicating with the corresponding first slots 6 are opened on both sides of the top plate 5. Bolts 9 are threadedly inserted into the corresponding first screw holes 7 and second screw holes 8. The bolts 9 can further improve the connection stability between the top plate 5 and the two support rods 3.

[0024] In addition, a hexagonal groove 16 is provided at one end opening of the jack 15. A hexagonal nut 17 adapted to its size is arranged in the hexagonal groove 16. One end of the screw rod 18 passes through multiple through holes 13 and is threadedly inserted into the hexagonal nut 17. The screw rod 18 can be fixedly connected through the hexagonal nut 17, so that the screw rod 18 is stably inserted into the jack 15 on the side of the bottom plate 1. Without the screw rod 18 detaching from the jack 15, the bottoms of the multiple stop rods 12 can always be inserted into the second slots 14 on the bottom plate 1. Without the stop rods 12 detaching from the bottom plate 1, the top plate 5 can always be installed at the tops of the two support rods 3.

[0025] Moreover, when the screw rod 18 is inserted into the through hole 13 at the bottom end of the stop rod 12, the bottom of the baffle at the top end of the stop rod 12 fits against the bottom of the inner wall of the corresponding groove 10. Pressure is exerted on the corresponding groove 10 through the baffles at the top ends of the multiple stop rods 12. The bottom ends of the stop rods 12 are fixed in the second slots 14 on the bottom plate 1 by the screw rod 18, so that the top plate 5 can be stably installed at the tops of the two support rods 3. Under the action of the stop rods 12, the top plate 5 cannot detach from the connection of the two support rods 3.

[0026] Also, the height of the fixing member 2 on the left side of the top of the bottom plate 1 is less than the height of the fixing member 2 on the right side of its top, and the height of the support rod 3 connected to the left fixing member 2 is greater than the height of the support rod 3 connected to the right fixing member 2. The tops of the two support rods 3 are at the same horizontal height. When the two support rods 3 are in a horizontal state, the support rod 3 on the right presses on the support rod 3 on the left. In this way, the top plate 5 can be installed at the tops of the two support rods 3, and the stacked bottom plate 1 and the two support rods 3 are more convenient for handling and storage, and can save a certain amount of occupied space.

[0027] Furthermore, stoppers 4 are fixedly installed at both ends of the top of the bottom plate 1. When the two support rods 3 are in a vertical state, the side walls of the two support rods 3 are respectively in contact with the two stoppers 4. Through the two stoppers 4, the two support rods 3 can be more stable when they are vertical on the bottom plate 1, avoiding the situation of the support rods 3 being skewed.
