Description

Technical Field

[0001] This utility model relates to the field of construction safety protection technology, and in particular to a climbable construction fence for use during backfilling operations. Background Technology

[0002] In construction projects, fencing is an essential safety protection and isolation facility. Traditional construction fencing is usually fixed to the ground by its foundation, and its height cannot be changed once it is set. However, in situations such as site backfilling and roadbed filling, the soil height at the working surface will continuously rise. If traditional fixed fencing is used, its effective protective height will continuously decrease as the bottom is buried, eventually losing its safety protection function. If the fencing is repeatedly dismantled and reinstalled during backfilling, there will be problems such as low construction efficiency, serious material waste, high costs, and poor operational safety. Therefore, there is an urgent need for a new type of fencing structure that can adapt to soil rise and maintain an effective protective height at all times. Summary of the Invention

[0003] This utility model aims to address the shortcomings of existing technologies by providing a simple, easy-to-operate, and reusable climbing construction fence for backfilling operations. It can be raised synchronously with the backfilling of soil, always maintaining the designed exposed height.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a climbing construction fence for use during soil filling operations, comprising a fence panel, a vertical guide rail system, a lifting and fixing system, and an internal support system;

[0005] The enclosure panel is an integral structure, and its outer panel frame is a truss structure, which is divided into upper chord, lower chord and vertical members, all of which are made of square tubes. The upper chord and lower chord are slidably connected to the vertical guide rail system on both sides through sliders, so that the enclosure panel can move vertically along the vertical guide rail system.

[0006] The vertical guide rail system is composed of multiple standard guide rail units that are detachably connected end to end by connectors and vertically anchored in the soil. The standard guide rail units are also equipped with locking devices for locking the enclosure panels.

[0007] The lifting and fixing system includes a fixed pulley that can be detachably installed at the top of the vertical guide rail system, lifting points installed on both sides of the top of the upper chord, and a winch placed on the ground. The wire rope on the winch is connected to the lifting points and guided by the fixed pulley.

[0008] The internal support system includes an adjustable-length support rod that is hinged at one end to the inside of the vertical guide rail system and at the other end to the surface of the backfilled soil.

[0009] Specifically, the standard guide rail unit has flanges at both the top and bottom, and the connecting parts are high-strength bolts that pass through the bolt holes of the adjacent flanges.

[0010] Specifically, the locking element is a pin or bolt. The vertical guide rail system has multiple positioning holes spaced vertically, and the slider has corresponding holes. The enclosure panel is locked by passing the pin or bolt through the positioning holes and the holes on the slider.

[0011] Specifically, the standard guide rail unit is a steel profile with a guide groove. The slider is slidably installed in the guide groove. Several limiting blocks are spaced apart on the front and rear inner walls of the guide groove. Rubber strips are installed on the side of the limiting blocks facing the slider.

[0012] Specifically, the contact surfaces of the slider and the guide groove are coated with polytetrafluoroethylene.

[0013] Specifically, the adjustable length support rod is a telescopic sleeve structure or a telescopic threaded rod structure, with a foot pad at the end that supports the soil.

[0014] In particular, the winch is mobile and is placed on the ground and staggered from the enclosure structure during operation.

[0015] The beneficial effects of this utility model are:

[0016] Highly adaptable: Through the extendable vertical guide rails and liftable enclosure panels, the enclosure height and the soil backfill height can be increased synchronously, always maintaining an effective safety protection height.

[0017] Highly efficient construction: The entire lifting and extension process is mechanized, which is simple and quick, greatly reducing the amount of demolition and reinstallation work in traditional methods, significantly improving construction efficiency and avoiding material waste.

[0018] Safe and reliable: The vertical guide rail provides a stable guidance and force path, and the internal adjustable support rod can effectively transfer horizontal forces such as wind loads to the backfilled soil. The overall structure has good stability and strong anti-overturning ability.

[0019] Economical and environmentally friendly: The main components of the system can be manufactured in a standardized manner and disassembled and reused repeatedly. The vertical guide rail unit can be pulled out after construction is completed, resulting in a high turnover rate and reducing the overall construction cost. Attached Figure Description

[0032] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0034] like Figures 1-7 As shown, a climbable construction fence for use during backfilling operations includes a fence panel 1, a vertical guide rail system 2, a lifting and fixing system 3, and an internal support system 4.

[0035] The enclosure panel 1 is an integral structure (the surface layer of enclosure panel 1 can be a 3-meter-high color steel sandwich panel). Its outer frame is a truss structure, consisting of an upper chord 101, a lower chord 102, and vertical members 103, all constructed of square tubing. The upper chord 101 and lower chord 102 are slidably connected to the vertical guide rail system 2 via sliders 104, allowing enclosure panel 1 to move vertically along the vertical guide rail system 2. The integral truss structure has high rigidity and good stability, effectively resisting wind loads and collision loads during construction.

[0036] The vertical guide rail system 2 is composed of multiple standard guide rail units 201 connected end-to-end via connectors 202 and vertically anchored in the soil. Each standard guide rail unit 201 is also equipped with a locking element 203 for locking the enclosure panel 1. Flanges 204 are located at both the upper and lower ends of each standard guide rail unit 201, and the connectors 202 are high-strength bolts passing through the bolt holes of adjacent flanges 204. Each standard guide rail unit 201 is a steel section with guide grooves, and the slider 104 is designed for sliding. Within the guide chute, several limiting blocks 205 are spaced apart on the front and rear inner walls. Rubber strips 206 are installed on the side of the limiting blocks 205 facing the slider 104. The contact surfaces of the slider 104 and the guide chute are coated with polytetrafluoroethylene (PTFE). The locking element 203 is a pin or bolt. Multiple positioning holes are spaced apart vertically on the vertical guide rail system 2, and corresponding holes are provided on the slider 104. The enclosure panel 1 is locked by the pin or bolt passing through the positioning holes and the holes on the slider 104. The standard guide rail unit 201 can be extended section by section to adapt to different backfill heights. The limiting blocks 205 cooperate with the rubber strips 206 to prevent the slider 104 from derailing and reduce impact. The PTFE coating effectively reduces friction and improves smoothness.

[0037] The lifting and fixing system 3 includes a detachable fixed pulley 301 mounted on top of the vertical guide rail system 2 (the bracket of the fixed pulley 301 is bolted to the flange 204 at the upper end of the standard guide rail unit 201 at the top, and the fixed pulley 301 is installed with a small angle of deviation (not exceeding 5°)), lifting points 302 mounted on both sides of the top of the upper chord 101, and a winch 303 placed on the ground. The wire rope 304 on the winch 303 is connected to the lifting points 302 and guided by the fixed pulley 301. The winch 303 is movable and is placed on the ground and staggered from the enclosure structure during operation. The lifting process is mechanized, simple to operate, and labor-saving; the angled design of the fixed pulley 301 avoids wear on the wire rope 304; the winch 303 is in a flexible position and does not affect the construction space.

[0038] The internal support system 4 includes an adjustable-length support rod 401, one end of which is hinged to the inside of the vertical guide rail system 2, and the other end of which is supported on the surface of the backfilled soil. The adjustable-length support rod 401 is a telescopic sleeve structure or a telescopic threaded rod structure, and its end supported on the soil is provided with a foot pad 402. The adjustable-length support rod 401 can transfer horizontal loads to the soil, enhancing the overall anti-overturning capacity; its length is adjustable to adapt to different soil surface heights; the foot pad 402 increases the contact area and prevents subsidence.

[0039] Specifically, when the adjustable length support rod 401 is a telescopic sleeve structure, it includes a sleeve with telescopic rods inserted at both ends. One telescopic rod is fixed to the sleeve by bolts or by a threaded locking cap. One telescopic rod is connected to the inside of the standard guide rail unit 201, and a foot pad 402 is installed at the bottom of the other telescopic rod. When the adjustable length support rod 401 is a telescopic threaded rod structure, it includes a threaded sleeve with threaded rods threaded at both ends. One threaded rod is connected to the inside of the standard guide rail unit 201, and a foot pad 402 is installed at the bottom of the other threaded rod.

[0040] During initial installation, the first standard guide rail unit 201 is driven deep enough into the ground to ensure initial stability. The enclosure panel 1 is then installed and locked. As backfilling progresses, a new standard guide rail unit 201 is attached to the top of the guide rail, a fixed pulley 301 is installed, a small winch 303 is placed, and a steel wire rope 304 is threaded through the fixed pulley 301 and installed on the lifting point 302 of the upper chord 101. All locking pins are removed, and the winch 303 is simultaneously operated to lift the enclosure panel 1 approximately 1 meter. The pins are then inserted to lock the enclosure at the new height. The internal adjustable length support rod 401 is adjusted to ensure it is flush with the soil surface. Backfilling can then continue, and the above steps are repeated to allow the enclosure to rise synchronously with the backfill until the designed backfill height is reached.

[0041] This utility model uses segmented height-adjusting guide rails and lifting equipment to raise the entire fence, which is then reinforced with internal support rods. This allows the fence to rise synchronously with the backfilling of soil, maintaining an effective protective height at all times. It has the advantages of high construction efficiency, safety and reliability, and reusability.
