Description

Technical Field

[0001] This utility model belongs to the field of construction auxiliary equipment, and relates to the structural and performance improvement of construction fences, especially a construction fence that can be raised and lowered for quick connection. Background Technology

[0002] Construction site fencing refers to a barrier erected around a construction site to protect it from disturbance and ensure safety. It is typically made of materials such as corrugated steel sheets, metal sheets, or plastic sheets. Construction site fencing serves several purposes: protecting the construction site from disturbance and ensuring safety; preventing unauthorized entry of personnel and vehicles, thus ensuring construction safety; ensuring smooth traffic flow and pedestrian safety, preventing traffic congestion and accidents; and maintaining the city's appearance and image. The installation of construction site fencing must be neat, aesthetically pleasing, and in accordance with urban planning requirements.

[0003] Most existing construction site fencing is either fixed or foldable. Fixed fencing, while offering better stability and strength, has a longer setup time and higher cost, and is generally used in large and medium-sized construction projects with long construction periods and high safety requirements. Foldable fencing is easy to carry and quickly set up, but its stability and strength are lower, and it is generally used for short-term or temporary facility maintenance site protection. Gas pipeline and ancillary facility repair and construction has its own unique characteristics. Firstly, problems are usually sudden and require rapid resolution. Secondly, due to the flammability and explosiveness of gas, the safety requirements at the construction site are high. Thirdly, gas pipelines and ancillary facilities are mostly buried underground, and the terrain conditions for burial vary. However, common foldable fencing cannot be raised and lowered with the ground surface, and its safety requirements do not meet the protection needs of gas construction.

[0004] For example, the "Easy-to-install and dismantle edge barrier" disclosed in Chinese patent document (application publication number CN119195578) includes a base rod and a baffle installed between adjacent base rods. The top of the baffle has a placement space, and a support plate is provided in the placement space. A clamping mechanism is provided on the support plate, and an ejection mechanism is provided in the placement space to drive the clamping mechanism to extend or retract into it. When the ejection mechanism and the clamping mechanism extend out of the placement space, the atomizing tube body can be installed on the clamping mechanism. The clamping mechanism includes a loading seat fixed to the top of the support plate. A limit rod is fixed in the loading seat. Two sets of clamping plates are symmetrically slidably installed on the limit rod, and a spring is sleeved on the limit rod corresponding to the side position of the clamping plate.

[0005] While the aforementioned edge-mounted fencing offers improvements in usability, the use of a clamping mechanism to fix the base rod to the baffle makes the installation process complex, time-consuming, and prone to deviations during use, potentially leading to installation failures. Furthermore, while the weight of the baffle is primarily supported by the base rod during lifting, the support provided by the base rod is limited, necessitating additional measures to secure the base rod to the supporting surface. This reduces the fencing's mobility and portability. Therefore, this edge-mounted fencing is essentially limited to use as a fixed baffle. Utility Model Content

[0006] The purpose of this invention is to provide a liftable and quick-connecting construction fence to solve the problems of insufficient lifting and portability of existing construction fences.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted:

[0008] A liftable and quick-connecting construction fence includes a support frame and a baffle. The support frame and the baffle are movably connected via a snap-fit ​​structure and a locking structure. The support frame includes a bottom support, a vertical support, and an inclined support. The bottom end of the vertical support is fixed to one end of the bottom support, and the other end of the bottom support is fixedly mounted with an inclined support between it and the upper part of the vertical support. The baffle includes a frame and a panel fixed inside the frame. The snap-fit ​​structure includes a longitudinal slot fixed to the outside of the vertical support. The longitudinal slot includes a connecting plate and a longitudinal plate. The longitudinal plate is parallel to the vertical support. One end of the connecting plate is fixed to the side of the vertical support, and the other end of the connecting plate is fixed to the longitudinal plate. The distance between the vertical support and the longitudinal plate is adapted to the width of the frame. The locking structure includes a sliding connecting ring, an inverted U-shaped pin, and a positioning sleeve set on the back of the frame. Multiple sets of positioning sleeves are set on the two vertical sides of the frame, and the sliding connecting ring is set in a groove on the back of the frame. The inverted U-shaped pin cooperates with the vertical support, the positioning sleeve, and the sliding connecting ring to achieve a lifting or horizontal locking connection between adjacent baffles.

[0009] To further achieve the objectives of this utility model, the following technical solutions may also be adopted:

[0010] As described above, the liftable and quick-connect construction fence has one set of longitudinal slots at the bottom, middle and top of the same side as the vertical support.

[0011] As described above, the liftable and quick-connect construction fence has a horizontal slot on the side of the bottom support. The horizontal slot includes a bottom plate and a horizontal plate. One end of the bottom plate is fixed to the lower edge of the bottom support, and the other end of the bottom plate is fixed to the lower edge of the horizontal plate. The distance between the horizontal plate and the bottom support is adapted to the width of the frame.

[0012] As described above, the liftable and quick-connect construction fence has two sets of transverse slots spaced apart on the same side of the bottom support.

[0013] As described above, the liftable and quick-connect construction fence has a sliding groove on a fixed plate, which is vertically positioned inside the frame; a locking block that cooperates with the sliding groove is provided on the sliding connecting ring.

[0014] As described above, the liftable and quick-connect construction fence has one set of sliding connecting ring and sliding groove respectively in the middle and upper part of the back of the fence.

[0015] As described above, the liftable and quick-connect construction fence has a bottom support and a vertical support both made of rectangular steel pipes. The upper end of the vertical support is open to cooperate with the side of the inverted U-shaped pin.

[0016] The advantages of this utility model are:

[0017] This lightweight, liftable, quick-connect construction fence is primarily installed using longitudinal or transverse slots between the baffle and the support frame, improving installation and dismantling efficiency. The lightweight baffle provides excellent support from the support frame, and during installation, its weight is mainly borne by the ground or other supporting structures, thus not increasing the load on the support frame. When adjacent baffles are installed in a planar or corner configuration, the baffles can be quickly locked and fixed using the interlocking of inverted U-shaped pins, positioning sleeves, and sliding connecting rings.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0034] In the description of the embodiments of this utility model, unless otherwise explicitly limited, terms such as setting, installing, and connecting should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0035] The folding wing assembly of this utility model is a component of a multi-functional miter saw. For ease of understanding, the folding wing assembly is described within the context of an embodiment of the multi-functional miter saw.

[0036] like Figures 1-5 As shown in the figure, this embodiment discloses a liftable and quick-connect construction fence, including a bracket 1 and a baffle 2. The bracket 1 and the baffle 2 are movably connected by a snap-fit ​​structure and a locking structure.

[0037] The bracket 1 includes a bottom support 11, a vertical support 12, and an inclined support 13. The bottom end of the vertical support 12 is fixed to one end of the bottom support 11, and the inclined support 13 is fixedly installed between the other end of the bottom support 11 and the upper part of the vertical support 12. The baffle 2 includes a frame 21 and a panel 22 fixed inside the frame 21.

[0038] In this embodiment, both the bottom support 11 and the vertical support 12 are constructed from rectangular steel tubes. Rectangular steel tubes, also known as square steel, have the advantages of being lightweight and strong. The flat length and width of the square steel facilitates contact between the bottom support 11 and the bottom surface or other supporting surfaces. Furthermore, the length of the bottom support 11 provides good support for the vertical support 12, improving the stability of the baffle 2 installation. Additionally, the inner cavity of the square steel can serve as an opening at the top of the vertical support 12, allowing for quick installation or removal of the bracket 1 and the baffle 2 by engaging with snap-fit ​​and locking mechanisms.

[0039] The frame 21 of the baffle 2 can also be made of square steel. The panel 22 is welded and fixed to the inside of the frame 21 around its perimeter, reducing the overall weight of the baffle 2. At the same time, multiple gaps or strip holes are opened on the panel 22 to reduce wind resistance and improve the appearance of the baffle 2.

[0040] See also Figures 1-3 The snap-fit ​​structure of this embodiment includes a longitudinal slot 3 fixed on the outside of the vertical support 12. The longitudinal slot 3 includes a connecting plate 31 and a longitudinal plate 32. The longitudinal plate 32 is parallel to the vertical support 12. One end of the connecting plate 31 is fixed to the side of the vertical support 12, and the other end of the connecting plate 31 is fixed to the longitudinal plate 32. The distance between the vertical support 12 and the longitudinal plate 32 is adapted to the width of the frame 21.

[0041] Therefore, the frame 21 can be quickly snapped together using the longitudinal plate 32 and the vertical support 12. One set of longitudinal slots 3 is provided at the bottom, middle, and top of the vertical support 12 on the same side. Multiple sets of longitudinal slots 3 ensure the vertical consistency of the bracket 1 and the baffle 2, and also improve the stability of the connection between the bracket 1 and the baffle 2.

[0042] like Figure 4 , Figure 5 As shown, the locking structure of this embodiment includes a sliding connecting ring 4, an inverted U-shaped pin 5, and a positioning sleeve 6 provided on the back of the frame 21. Multiple sets of positioning sleeves 6 are provided on the two vertical sides of the frame 21, and the sliding connecting ring 4 is provided in the groove on the back of the frame 21.

[0043] The inverted U-shaped pin 5, together with the vertical support 12, the positioning sleeve 6, and the sliding connecting ring 4, enables the lifting or horizontal locking connection of adjacent baffles 2.

[0044] This lightweight, liftable, quick-connect construction fence is mainly installed via longitudinal slots 3 or transverse slots 7 between the baffle 2 and the bracket 1, improving installation and disassembly efficiency. The baffle 2 is lightweight, and the bracket 1 provides good support for the baffle 2. When the baffle 2 is lifted and installed, its weight is mainly borne by the ground or other supports, thus not increasing the load on the bracket 1. When adjacent baffles 2 are installed in a plane or at an angle, the baffle 2 can be quickly locked and fixed by using the interlocking of the inverted U-shaped pin 5, the positioning sleeve 6, and the sliding connecting ring 4.

[0045] like Figure 1 , Figure 3 As shown, in this embodiment, a horizontal slot 7 is provided on the side of the bottom support 11. The horizontal slot 7 includes a bottom plate 71 and a horizontal plate 72. One end of the bottom plate 71 is fixed to the lower edge of the bottom support 11, and the other end of the bottom plate 71 is fixed to the lower edge of the horizontal plate 72. The distance between the horizontal plate 72 and the bottom support 11 is adapted to the width of the frame 21.

[0046] Two sets of transverse slots 7 are spaced apart on the same side of the bottom support 11. The transverse slots 7 are mainly used for the turning connection of adjacent baffles 2, such as at right angles. In this case, the lower part of the frame 21 is secured in the transverse slot 7, and the lower part of the baffle 2 is connected from the outside using the transverse slot 7. The upper inner side of the baffle 2 is connected using a sliding connecting ring 4, an inverted U-shaped pin 5, and a positioning sleeve 6 on the back of the frame 21. The upper and lower, inner and outer parts cooperate to achieve a stable connection between the baffle 2 and the bracket 1.

[0047] The slide groove is formed on the fixed plate 8, which is vertically positioned inside the frame 21; the sliding connecting ring 4 is provided with a locking block that cooperates with the slide groove. One set of connecting ring and slide groove are respectively provided in the middle and upper part of the back of the baffle 2.

[0048] The sliding connecting ring 4 is mainly used to facilitate the lifting and lowering of adjacent baffles 2. Figure 5 As shown, when the plane below the right baffle 2 is raised, the entire right baffle 2 will rise. Adjusting the position of the sliding connecting ring 4 to engage with the left connecting ring and the inverted U-shaped pin 5 allows for a locking connection between the baffle 2 and the inner side of the bracket 1. The specifications of the inverted U-shaped pin 5 are replaceable to allow for the use of inverted U-shaped pins 5 with different spacings according to the actual spacing of the sliding connecting ring 4 and the positioning sleeve 6.

[0049] All technical contents not described in detail in this utility model are publicly known technologies. 。
