Description

Technical Field

[0001] This utility model relates to the field of construction protection equipment technology, specifically to a prefabricated protective fence for construction. Background Technology

[0002] In construction, there are certain standardized requirements for construction protection. Generally, the method of protection is determined according to the construction period. For simple, short-term construction, it is generally only necessary to use sheet metal fencing to enclose and protect the construction area. However, if the construction period is long, it is generally necessary to use higher-level prefabricated protective fencing.

[0003] For ease of transportation, prefabricated protective fencing is generally installed in a split manner. Depending on the construction period, when the rigidity of the protective fencing cannot meet the requirements for long-term standing, it needs to be used with a base. The base can be cast with cement or a specific type of channel steel or I-beam. During construction, the base is first fixed to the ground, and then the protective panel is inserted and fixed to the base to form a protective fencing similar to a wall.

[0004] Because some construction sites have a certain slope and the soil is relatively loose after the foundation pit is excavated, when there is a sudden heavy rainfall, the water flow outside the protective fence will be blocked and will flow along the protective fence. The water flow inside the fence will also be blocked and cannot be discharged in time. If most of it flows into the foundation pit, it will erode the soil on the inner wall of the foundation pit and affect subsequent construction. Utility Model Content

[0005] To overcome the above-mentioned defects, the purpose of this utility model is to provide a prefabricated protective fence for building construction, which can not only realize the function of protecting the foundation pit, but also divert rainwater, further ensuring the safety of the foundation pit and simplifying subsequent construction.

[0006] To achieve the above objectives, this utility model provides a prefabricated protective fence for building construction, characterized in that it includes a base and a fence panel, wherein the lower end of the fence panel is limited to the base;

[0007] The enclosure panel has storage slots on both sides, and water guiding devices are installed in the storage slots.

[0008] The water guiding device includes a connecting plate, a water guiding plate, and a traction rope. The two sides of the connecting plate are hinged to the enclosure plate, and the lower end of the water guiding plate is snapped into the connecting plate. One end of the traction rope is fixedly connected to the water guiding plate, and the other end is fixedly connected to the enclosure plate. A limiting lock block for limiting the rotation of the water guiding device is provided at the top of the storage groove.

[0009] The bottom of the enclosure panel is also provided with a drainage trough, and the storage slot is provided with a drainage hole that connects to the drainage trough.

[0010] Preferably, the enclosure panel has connecting grooves on both sides along its length, and a through hole is provided on the enclosure panel. A connecting post adapted to the connecting groove is inserted into the through hole, and two adjacent connecting grooves are slidably connected by the connecting post.

[0011] Preferably, the water guide plate is a corrugated plate with a wave pattern.

[0012] Preferably, both ends of the connecting post are provided with threaded holes adapted to the hinge.

[0013] Preferably, the side of the connecting column is also provided with a slot adapted to the corrugated plate. When multiple corrugated plates are arranged side by side, two adjacent corrugated plates are engaged and confined within the slot.

[0014] Preferably, the base is a channel steel or an I-beam, and the channel of the channel steel or I-beam is used to engage and limit the enclosure plate.

[0015] The beneficial technical effects achieved by this utility model after adopting the above technical solution are as follows:

[0016] 1. Due to the installation of a base and enclosure panels, and the inclusion of a water guiding device within the enclosure panels' storage slots, when protection is required, the connecting plates and water guiding plates on both sides can be opened, and the angle can be limited by traction ropes. This provides protection for the top and sides of the foundation pit, especially by guiding the water flow through drainage channels to the outside of the foundation pit. This is more conducive to subsequent construction, shortens the construction cycle, protects construction equipment, and especially prevents the foundation pit from collapsing due to rainwater erosion, significantly increasing the safety factor.

[0017] 2. The water guide plate is made of corrugated sheet. Corrugated sheet is often used as a simple protective unit in construction, so it can be purchased directly. After being combined with the existing connecting plate, it forms a simple water guide device. At the same time, corrugated sheet has good rigidity, low cost, and the corrugated grooves have a built-in water guiding effect. Subsequent construction is simple and storage is also very convenient. It can be easily modified on the existing protective fence.

[0018] 3. Due to the limited width of the corrugated sheet, multiple corrugated sheets are connected on both sides by slots, and then fixed at the bottom with hinges and other connecting columns. This greatly increases the protection area while ensuring the stability of the water guide plate after connection. Rainwater collected by multiple water guide plates is diverted to the designated location through drainage channels, which can greatly protect the safety of the foundation pit.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0031] See Figures 1-6 This utility model provides a prefabricated protective fence for construction sites, including a base 1 and a fence panel 2, with the lower end of the fence panel 2 confined to the base 1. In practical use, if the fence panel 2 has sufficient rigidity, it can generally be directly installed around the construction pit 4 and supported by ground bolts and diagonal braces. However, if the construction period is long or the ground is not flat enough, the base 1 is generally required. The base 1 can be made of channel steel or I-beams, both of which are mature existing technologies and can be directly purchased. This utility model uses I-beams. After the I-beams are fixed, the fence panel 2 is placed in the grooves of the channel steel and the I-beams. After installation, the grooves of the channel steel or I-beams and the drainage channel 24 work together to achieve drainage.

[0032] The enclosure panel 2 has storage slots 21 on both sides, and a water guiding device 3 is installed in the storage slots 21. The water guiding device 3 includes a connecting plate 31, a water guiding plate 32, and a traction rope 33. The two sides of the connecting plate 31 are hinged to the enclosure panel 2, and the lower end of the water guiding plate 32 is snapped into the connecting plate 31. One end of the traction rope 33 is fixedly connected to the water guiding plate 32, and the other end is fixedly connected to the enclosure panel 2. A limiting lock block 34 for limiting the rotation of the water guiding device 3 is provided at the top of the storage slot 21. See also Figure 1 The enclosure panel 2 serves as basic protective equipment, and is limited by a limit lock block 34 to prevent the water guide plate 32 and other equipment in the storage trough 21 from opening on their own. The limit lock block 34 can be made of a plate with a certain width and fixed to an appropriate position on the enclosure panel 2 with pins, and can rotate at a certain angle.

[0033] The bottom of the enclosure panel 2 is also provided with a drainage channel 24, and the storage slot 21 is provided with a drainage hole 25 that connects to the drainage channel 24. See also Figures 2-4 When protection of the foundation pit 4 is required, the water guide plate 32 is opened, and the tilt angle of the water guide plate 32 is adjusted using the traction rope 33. The tilt angle should be as large as possible while ensuring safety. Most of the rainwater flows downwards through the water guide plate 32 to the drainage hole 25, enters the drainage trough 24, and flows to the outside of the foundation pit 4. After the water guide plate 32 of this invention is opened, it can guide and drain most of the rainwater that would otherwise fall into the foundation pit 4, simplifying subsequent construction, but it cannot achieve complete waterproofing.

[0034] The enclosure panel 2 of this utility model has connecting grooves 22 on both sides along its length. The enclosure panel 2 has through holes, and connecting posts 23 adapted to the connecting grooves 22 are inserted into the through holes. Adjacent connecting grooves 22 are slidably engaged by the connecting posts 23. The connecting posts 23, located within the through holes of the enclosure panel 2, serve as counterweights and supporting ribs, and can also further ensure the rigidity of the enclosure panel 2. When needed, their ends are secured with nuts, and the panel can be removed.

[0035] When two adjacent enclosure panels 2 are set side by side, the connecting column 23 can be snapped into the connecting groove 22 for uninterrupted connection. In actual use, in order to ensure that no collapse occurs, diagonal bracing is still required every few enclosure panels 2 for wind protection.

[0036] The water guide plate 32 of this utility model is a corrugated plate with a wave pattern. Corrugated plates with a wave pattern have many applications in the protection of building foundation pits. They are generally made of galvanized iron sheet, stamped into a certain wave pattern to increase rigidity. The corrugated plate with a wave pattern is relatively thin, and a connecting plate 31 is provided at the bottom connection for support and rotation.

[0037] The connecting post 23 of this utility model has threaded holes at both ends that are adapted to the hinge. The connecting post 23 is inserted into the through hole. One function of the threaded hole is to connect bolts for easy removal, and it can also be used to connect hinges to strengthen the connection. See also Figure 5 and Figure 6 Since the foundation pit 4 is relatively deep, when the supporting height is insufficient, two connecting columns 23 are required, and the bottom of the connecting columns 23 are fixed to improve stability.

[0038] The connecting post 23 of this utility model also has a slot 231 on its side that is adapted to the corrugated sheet. When multiple corrugated sheets are arranged side by side, two adjacent corrugated sheets are engaged and confined within the slot 231. When two baffle plates 2 are arranged side by side, gaps may exist between the corrugated sheets due to installation errors. The two water guide plates 32 are connected by the slots 231 on both sides of the connecting post 23. After connection, self-tapping screws or other auxiliary parts are generally used for reinforcement and fixation. Due to the large tilt angle, the connecting post 23 is generally used to increase safety. If the expected rainfall is significantly higher than normal, a water pump is usually installed at the drainage channel 24 for faster drainage and less water accumulation.

[0039] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
