Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a foundation pit fence for municipal construction. Background Art

[0002] Foundation pit fences are facilities used to surround the perimeter of foundation pits during municipal engineering construction, serving as safety protection and warning. However, most existing foundation pit fences are placed on the ground through bases. This installation method is often unstable and prone to tipping over.

[0003] The reasons for this phenomenon are mostly external factors. For example, in strong winds, the wind exerts a large lateral force on the fence. If the fence's wind resistance is insufficient, it will collapse. Pedestrians, vehicles or equipment may accidentally hit the fence, causing it to collapse and lose protection for the foundation pit.

[0004] In summary, we propose an underground liftable foundation pit fence to prevent the fence from tipping over and is suitable for a variety of terrain environments to solve the above-mentioned problems. Summary of the invention

[0005] The purpose of the present invention is to provide a foundation pit fence for municipal construction, which can effectively solve the above-mentioned problems.

[0006] To achieve the above object, the present invention proposes the following scheme:

[0007] A foundation pit fence for municipal construction, comprising a railing and a crossbar, wherein the crossbar is transversely arranged at the side end of the railing and is clamped with the railing, and further comprising an underground rod buried in the ground, wherein a thread groove is provided inside the underground rod, and an outer surface of the railing is provided with an external thread connected with the thread groove. The railing is raised and lowered on the inner thread of the underground rod through the surface external thread, and the length of the railing is equivalent to that of two underground rods, wherein the lower half of the railing is threadedly inserted into the thread groove, and the upper half protrudes from the ground;

[0008] The connection between the outer surface of the handrail and the buried rod is threadedly connected with a sealing mechanism;

[0009] The outer surface of the upper half of the railing is connected with a plurality of mounting rings through threads. The mounting rings can be threadedly rotated and raised and lowered. A convex block is welded on the outer surface of the mounting ring. A slot is provided on the upper end of the convex block for clamping the cross bar.

[0010] A reinforcement ring is welded on the outer surface of the upper end of the buried rod, and a plurality of ground nails are installed in a ring shape at the lower end of the reinforcement ring. When the reinforcement ring fits the ground, the ground nails are inserted into the ground.

[0011] A sealing groove is arranged at the upper end of the reinforcing ring, a first screw hole is arranged through the center of the sealing mechanism, and the sealing mechanism is threadedly lifted and lowered on the outer surface of the railing through the first screw hole.

[0012] A sealing ring matched with the sealing groove is arranged at the lower end of the sealing mechanism. When the sealing mechanism descends to the bottom, the sealing ring is inserted into the sealing groove to form a seal.

[0013] A second screw hole is provided at the center of the installation ring, and the direction of the protrusion is changed and the lifting and lowering are performed on the outer surface of the railing through the second screw hole.

[0014] The two ends of the cross bar are inserted into the slots at the upper end of the protrusion and are connected with the protrusion by their own weight.

[0015] A warning strip is pasted on the outer surface of the crossbar.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The foundation pit fence for municipal construction of the present invention has underground rods that are buried underground and connected to the railings through threads. Compared with railings directly installed on the ground, this method can form a higher stability with the ground and is not easy to topple due to external forces, thereby greatly improving the overall stability of the fence.

[0018] (2) The design of the screw connection between the railing and the buried rod of the municipal construction foundation pit fence of the present invention can also adjust the height of the railing to a certain extent. This feature enables it to achieve effective protection by adjusting the height of the railing, thereby being suitable for various engineering requirements.

[0019] (3) The municipal construction foundation pit fence of the present invention, the reinforcement ring welded on the outer surface of the upper end of the buried rod and the ground nails installed in a ring at the lower end of the reinforcement ring, can provide additional protection for the overall stability of the fence, making it suitable for complex ground and further improving the overall stability of the fence.

[0020] (4) The sealing mechanism of the municipal construction foundation pit fence of the present invention effectively protects the connection between the buried rod and the railing, preventing rainwater from seeping in and causing rust on the threads, thereby increasing the service life and stability of the fence.

[0021] (5) The municipal construction foundation pit fence of the present invention has a mounting ring that can be threadedly rotated on the railing, thereby changing the direction of the protrusion, thereby changing the installation angle of the cross bar according to the shape of the foundation pit, flexibly adjusting the shape of the fence, and improving the overall applicability.

[0022] (6) The municipal construction foundation pit fence of the present invention has cross bars that are snapped into the slots, and the number of cross bars can be adjusted according to the number of mounting rings. The more mounting rings there are, the more cross bars there are, and the stronger the protection capability is. Cross bars can be added in dangerous areas as needed to improve the protection strength and enhance the overall applicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] See also Figure 1-8 A foundation pit fence for municipal construction, comprising a railing 2 and a crossbar 5, wherein the crossbar 5 is transversely arranged at the side end of the railing 2 and is clamped with the railing 2, and further comprising an underground rod 1 buried in the ground, wherein a thread groove 11 is provided inside the underground rod 1, and an external thread 21 is provided on the outer surface of the railing 2 and is threadedly connected with the thread groove 11, and the railing 2 is raised and lowered on the internal thread of the underground rod 1 through the surface external thread 21, and the length of the railing 2 is equivalent to that of two underground rods 1, and the lower half of the railing 2 is threadedly inserted into the thread groove 11, and the upper half protrudes from the ground;

[0034] The connection between the outer surface of the handrail 2 and the buried rod 1 is threadedly connected with a sealing mechanism 3;

[0035] The outer surface of the upper half of the railing 2 is connected with several mounting rings 4 through threads. The mounting rings 4 can be threadedly rotated and raised and lowered. A protrusion 42 is welded on the outer surface of the mounting ring 4. A slot 421 is provided at the upper end of the protrusion 42 for clamping the cross bar 5. When in use, the buried rod 1 is buried in the ground, and then the lower half of the railing 2 is threadedly inserted into the thread groove 11 to achieve the screw connection between the railing 2 and the buried rod 1. Compared with the railing 2 directly placed on the ground through the base, this design can form an extremely high and stable connection with the ground and will not fall down due to external force, which greatly improves the overall stability of the fence. At the same time, the railing 2 is threadedly connected to the buried rod 1, and the height of the railing 2 can be adjusted to a certain extent to meet various engineering requirements, thereby improving stability and applicability.

[0036] Furthermore, a reinforcement ring 12 is welded to the outer surface of the upper end of the buried rod 1, and a plurality of ground nails 121 are installed in a ring at the lower end of the reinforcement ring 12. When the reinforcement ring 12 is in contact with the ground, the ground nails 121 are inserted into the ground. When in use, after the buried rod 1 is buried in the ground, the ground nails 121 at the lower end of the reinforcement ring 12 are inserted into the ground. The reinforcement ring 12 increases the contact area with the ground and further improves the overall stability through the ground nails 121.

[0037] Furthermore, a sealing groove 122 is provided at the upper end of the reinforcement ring 12, and a first screw hole 31 is provided at the center of the sealing mechanism 3, and the sealing mechanism 3 is threadedly raised and lowered on the outer surface of the railing 2 through the first screw hole 31. When in use, after the railing 2 is threadedly inserted into the buried rod 1, the staff can thread the sealing mechanism 3 onto the outer surface of the railing 2 through the first screw hole 31, and thread it downward to complete the installation of the sealing mechanism 3.

[0038] Furthermore, a sealing ring 32 adapted to the sealing groove 122 is provided at the lower end of the sealing mechanism 3. When the sealing mechanism 3 descends to the bottom, the sealing ring 32 is inserted into the sealing groove 122 to form a seal. When in use, the sealing ring 32 is specifically made of a rubber material. When the sealing ring 32 is inserted into the sealing groove 122, the connection between the buried rod 1 and the railing 2 can be sealed and protected, and rainwater infiltration can be prevented from causing rust on the threads, thereby affecting the lifting and lowering effect of the railing 2.

[0039] Furthermore, a second screw hole 41 is provided at the center of the mounting ring 4, and the direction of the protrusion 42 is changed and raised and lowered on the outer surface of the railing 2 through the second screw hole 41. When in use, the direction of the protrusion 42 can be changed arbitrarily when the thread of the mounting ring 4 is rotated. The direction of the protrusion 42 can be rotated to install the cross bar 5 at different angles, such as Figure 1 and Figure 8 As shown, the overall shape of the fence can be changed according to the shape of the foundation pit, thereby improving the overall applicability.

[0040] Furthermore, both ends of the cross bar 5 are inserted into the slots 421 on the upper end of the protrusion 42, and are engaged with the protrusion 42 by their own weight. When in use, the cross bar 5 is placed inside the slots 421 on the protrusion 42 from top to bottom according to the number and direction of the mounting rings 4, as shown in FIG. Figure 7 As shown, in order to form lateral protection to prevent pedestrians and vehicles from approaching the foundation pit, the cross bar 5 can be adjusted according to the number of mounting rings 4, that is, the more mounting rings 4 there are, the more cross bars 5 can be installed, and the stronger the protection capability formed is. Therefore, more cross bars 5 can be added at locations prone to accidents to improve the protection strength, reduce the occurrence of accidents, and thus increase the overall applicability.

[0041] Furthermore, a warning strip 51 is pasted on the outer surface of the cross bar 5. When in use, the warning strip 51 is specifically made of an aluminum foil material. The warning strip 51 made of aluminum foil is not easy to be damaged and is suitable for the environment around the foundation pit. At the same time, it has strong reflective properties and is very eye-catching. It can attract people's attention during the day or at night, thereby clearly conveying danger warnings and preventing accidents.

[0042] In summary, the foundation pit fence for municipal construction proposed by the present invention, when in use, first, bury the buried rod 1 in the ground, and a reinforcement ring 12 is welded on the outer surface of the upper end of the buried rod 1. When the reinforcement ring 12 is in contact with the ground, a plurality of ground nails 121 installed in a ring shape at its lower end are inserted into the ground. The reinforcement ring 12 increases the contact area with the ground and improves the overall stability through the ground nails 121. Then, the lower half of the railing 2 is threadedly inserted into the thread groove 11 opened inside the buried rod 1 through the external thread 21 on the outer surface, so as to realize the railing 2 and the ground. The buried rod 1 is screwed together. Since the length of the railing 2 is equivalent to that of two buried rods 1, after the lower half is inserted into the threaded groove 11, the upper half protrudes from the ground, and stability can be guaranteed. This method makes the railing 2 firmly connected to the ground, and the railing 2 can be adjusted in height to a certain extent by threaded lifting to meet various engineering requirements. After the railing 2 is screwed together with the buried rod 1, the staff will thread the sealing mechanism 3 on the outer surface of the railing 2 through the first screw hole 31 opened in the center and rotate it downward. The lower end of the sealing mechanism 3 is provided with a sealing ring 32 that is compatible with the sealing groove 122 at the upper end of the reinforcement ring 12. When the sealing mechanism 3 drops to the bottom, the sealing ring 32 is inserted into the sealing groove 122 to form a seal. The sealing ring 32 is made of rubber material, which can prevent rainwater from seeping in and causing the thread to rust, thereby ensuring the lifting effect of the railing 2 and the overall stability effect. Afterwards, the mounting ring 4 is installed on the outer surface of the upper half of the railing 2 according to needs. The mounting ring 4 is threaded and threaded on the outer surface of the railing 2 through the second screw hole 41 opened in the center. , and the direction of the protrusion 42 can be changed at will, so that the fence as a whole can be suitable for foundation pits of various shapes. Finally, the two ends of the cross bar 5 are inserted into the slot 421 at the upper end of the protrusion 42. The number of cross bars 5 can be adjusted according to the number of mounting rings 4. The more mounting rings 4 there are, the more cross bars 5 can be installed, and the stronger the protection ability. A warning strip 51 made of aluminum foil is pasted on the outer surface of the cross bar 5. It has strong reflectivity and is not easy to be damaged. It can attract people's attention during the day or at night, clearly convey danger warnings, and prevent accidents.
