Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a municipal edge railing that can be converted into a temporary construction enclosure. Background Technology

[0002] During construction, temporary fencing is needed to separate the construction area from the outside world to ensure safe construction. Currently, temporary construction fencing commonly uses a concrete foundation + color steel plate structure or independent steel column fencing. For example, Chinese utility model patent CN202120345678.9 discloses a prefabricated construction fencing, which requires on-site pouring of concrete foundation, column spacing of 2.5-3m, and fencing panels fixed by welding.

[0003] Because existing temporary fencing technology does not utilize existing municipal facilities and adopts an independent load-bearing system, it results in structural redundancy and generally suffers from the following technical problems:

[0004] 1. Destructive construction: When pouring concrete foundation, it is necessary to break up the sidewalk tiles and base layer. The construction of a single square meter of concrete foundation will result in 2.3 square meters of sidewalk damage. The cost of restoring the sidewalk after construction is about 450 yuan / square meter, which increases the construction cost.

[0005] 2. Material waste: After a single use, 60% of the components of the temporary enclosure cannot be reused due to welding deformation. The steel utilization rate is only 35%-40%, resulting in low reusability and a large amount of material waste.

[0006] 3. Inefficient construction: The installation of a single set of fencing (6m) requires 2 workers and 4 hours, with an average daily installation volume of less than 15m. The labor cost is high and the installation efficiency is low.

[0007] Therefore, there is a need for a municipal edge railing that can be converted into a temporary construction fence, which can solve the problems of destructive construction, material waste during dismantling, and inefficient installation of temporary fences in the existing technology. Summary of the Invention

[0008] The purpose of this utility model is to provide a municipal edge railing that can be converted into a temporary construction fence, which can solve the problems of existing temporary fences requiring destructive construction, material waste during dismantling, and inefficient installation.

[0009] To achieve the above objectives, the technical solution of this utility model is as follows:

[0010] A municipal edge railing that can be converted into a temporary construction enclosure includes: clamps, connecting brackets, enclosure uprights, and diagonal braces. The enclosure uprights are vertically installed on the sidewalk outside the municipal railing. The enclosure uprights are connected to the uprights of the municipal railing via clamps. Several enclosure uprights are spaced apart along the installation direction of the municipal railing. Standardized railing panels are installed between adjacent enclosure uprights to form a temporary enclosure. One end of the connecting bracket is connected to one of the clamps, and one end of the diagonal brace is connected to the other end of the connecting bracket. The other end of the diagonal brace is fixed to the ground inside the municipal railing, so that the diagonal brace is inclined and supported between the temporary enclosure and the ground. Several diagonal braces are spaced apart along the installation direction of the municipal railing.

[0011] Each of the aforementioned clamping components includes a type I clamp, a U-shaped clamp, and a locking component; the U-shaped clamp is a U-shaped structure with one end open, and is fitted onto the outside of the fence post and the municipal railing post; the type I clamp passes through the open end of the U-shaped clamp and is locked and fixed by a pair of locking components, so that the type I clamp abuts against the post of the municipal railing post, and the other end of the U-shaped clamp abuts against the fence post.

[0012] A gasket is provided between the type I code and the locking component.

[0013] The side of the type I code away from the upright is fitted and connected to one end of the connecting code, so that the side of the type I code away from the upright, one end of the connecting code, and the open end of the U-shaped code are connected together by a pair of locking parts.

[0014] A gasket is provided between one end of the connecting code and the locking member.

[0015] The cross-section of the connecting code is a U-shaped structure with an opening at one end. One end of the diagonal brace is inserted into the opening of the connecting code and locked and fixed by rotating the connecting piece, so that the diagonal brace is inclined between the ground and the connecting code.

[0016] The other end of the diagonal brace is equipped with a counterweight, which is placed on the ground.

[0017] The angle between the diagonal brace and the ground is 55°-60°.

[0018] Both ends of the fence posts have C-shaped slots, and both ends of the standardized fence panels have C-shaped inserts. The C-shaped inserts are matched and inserted into the C-shaped slots, so that the standardized fence panels can be detachably installed between two adjacent fence posts.

[0019] The spacing between the fence posts is 1.5-1.8m.

[0020] Compared with the prior art, this utility model has the following advantages:

[0021] 1. This utility model directly connects the fence posts to the municipal railing posts through several clamps, utilizing the existing posts for load-bearing. This eliminates the need for pouring concrete foundations, reducing the amount of concrete foundation construction by 90% and avoiding destructive construction and the costs required for subsequent restoration.

[0022] 2. This utility model installs the fence posts on the posts of municipal railings, sets the fence posts according to the standard spacing of the posts and installs standardized railing panels, so that the entire temporary fence can be designed and manufactured in a standardized manner. The whole structure is installed by screwing and plugging, which makes it convenient and quick to assemble and disassemble. The installation efficiency can be increased to 2 sets / person·hour (6m / set). The number of times it can be reused after disassembly is ≥10 times, which greatly reduces the waste of materials.

Detailed Implementation

[0030] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a municipal edge railing that can be converted into a temporary construction fence, according to this utility model. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0031] Please see the appendix Figure 1 A municipal edge railing that can be converted into a temporary construction enclosure includes clamps 02, connecting brackets 03, enclosure posts 05, and diagonal braces 07. The enclosure posts 05 are vertically installed on the sidewalk 06 outside the municipal railing 04. The enclosure posts 05 are connected to the posts 041 of the municipal railing 04 via clamps 02. Several enclosure posts 05 are spaced apart along the installation direction of the municipal railing 04. Standardized guardrail panels (not shown in the figure) are installed between adjacent enclosure posts 05 to form a temporary enclosure. One end of the connecting bracket 03 is connected to one of the clamps 02, and one end of the diagonal brace 07 is connected to the other end of the connecting bracket 03. The other end of the diagonal brace 07 is fixed to the ground inside the municipal railing 04, so that the diagonal brace 07 is inclined and supported between the temporary enclosure and the ground. Several diagonal braces 07 are spaced apart along the installation direction of the municipal railing 04.

[0032] Preferably, the fence post 05 can be made of Q235B steel, and its cross-sectional dimensions can be the same as those of the post 041 of the municipal railing 04, such as a 100mm×100mm square tube. The length of the fence post 05 is determined according to the required fence height. For example, the standard height is 1.2m higher than the height of the municipal railing 04, and the total height is usually 2.5m.

[0033] The spacing of the fence posts 05 can be the same as the spacing of the posts 041 of the municipal railing 04, usually 1.5m. This allows the fence posts 05 to be directly connected and fixed to the posts 041 via clamps 02, ensuring the stability of the entire temporary fence setup. Furthermore, it eliminates the need for concrete foundation pouring, thus avoiding destructive construction and subsequent restoration costs.

[0034] The standard spacing of the uprights 041 of the municipal railing 04 is usually 1.5m. The standardized railing panels can be manufactured according to this standard spacing. The standardized railing panels can be made of galvanized steel plate with a thickness of 2mm and a size of 1.5m×1.2m. They can be directly installed vertically between adjacent fence uprights 05 to improve installation efficiency.

[0035] The number of clamps 02 can be adjusted according to actual connection requirements. Usually, three clamps are set. Two clamps 02 are 300mm and 800mm away from the sidewalk 06, respectively. The other clamp is located 200mm below the top of the upright 041 to ensure the vertical stability and reliability of the fence upright 05.

[0036] Diagonal braces 07 are used to provide support for temporary fences to resist horizontal forces and prevent temporary fences from tipping over under external forces. The spacing of diagonal braces 07 can be adjusted according to actual support needs and can be arranged one-to-one with fence uprights 05.

[0037] Please see the appendix Figure 2 and attached Figure 3 Each clamp 02 includes a type 1 clamp 021, a U-shaped clamp 022, and a locking element 023. The U-shaped clamp 022 is a U-shaped structure with one end open. The U-shaped clamp 022 is fitted onto the outside of the uprights 041 of the fence post 05 and the municipal railing 04. The type 1 clamp 021 passes through the open end of the U-shaped clamp 022 and is locked and fixed by a pair of locking elements 023, so that the type 1 clamp 021 abuts against the upright 041 of the municipal railing 04, and the other end (closed end) of the U-shaped clamp 022 abuts against the fence post 05.

[0038] Preferably, the U-shaped bracket 022 can be made by bending a φ16mm steel bar into a U-shape, with two layers of U-shaped steel bars arranged vertically at intervals as one U-shaped bracket 022. The opening width of the U-shaped bracket 022 is 120mm, and the opening of the U-shaped bracket 022 is threaded to cooperate with the locking member 023. The locking member 023 can be an 8.8 grade M16 bolt.

[0039] The type 1 code 021 is made of steel bars with a diameter smaller than that of the U-shaped code 022. The length of the type 1 code 021 is greater than the width of the U-shaped code 022. The opening of the U-shaped code 022 has a hole for the type 1 code 021 to pass through. Preferably, the opening can be an oblong hole, and the type 1 code 021 can move along the oblong hole to ensure that the closed ends of the type 1 code 021 and the U-shaped code 022 can be tightly fitted against the fence posts 05 and 041.

[0040] Please see the appendix Figure 3 A gasket 024 is provided between the type 1 code member 021 and the locking member 023.

[0041] Preferably, the gasket 024 can be a metal gasket or a rubber gasket to improve the connection reliability between the type 1 clamp 021 and the locking member 023. The three clamping members 02 can share one gasket 024 or use three gaskets 024 independently.

[0042] Please see the appendix Figure 4 and attached Figure 5 The side of the type 021 away from the upright 041 is attached to one end of the connecting code 03, so that the side of the type 021 away from the upright 041, one end of the connecting code 03 and the open end of the U-shaped code 022 are connected together by a pair of locking parts 023.

[0043] Preferably, the connecting code 03 can be made by bending a steel plate with a thickness of 10mm and a length of 300mm. One end (closed end) of the connecting code 03 is reserved with a hole for the open end of the U-shaped code 022 to pass through, so as to connect the connecting code 03 to the clamp 02.

[0044] Please see the appendix Figure 5 A gasket 024 is provided between one end of the connecting code 03 and the locking member 023.

[0045] Preferably, the gasket 024 can be a metal gasket or a rubber gasket to improve the connection reliability between the connecting piece 03 and the locking piece 023.

[0046] Please see the appendix Figure 4 and attached Figure 5 The cross-section of the connecting code 03 is a U-shaped structure with an opening at the other end. One end of the diagonal brace 07 is inserted into the opening of the connecting code 03 and locked and fixed by rotating the connecting piece 01, so that the diagonal brace 07 is inclined between the ground and the connecting code 03.

[0047] Preferably, the diagonal brace 07 can be made of Φ48mm×3.5mm steel pipe, and the length of the steel pipe can be selected according to the actual support requirements. The rotating connector 01 can be made of M20 through bolts. Through holes are opened on both sides of the connecting bracket 03 and one end of the diagonal brace 07 for inserting M20 through bolts, so that the diagonal brace 07 can be rotatably and adjustably connected to the connecting bracket 03.

[0048] Both ends of the fence uprights 05 are provided with C-shaped slots (not shown in the figure), and both ends of the standardized fence panels are provided with C-shaped inserts. The C-shaped inserts are matched and inserted into the C-shaped slots, so that the standardized fence panels can be detachably installed between two adjacent fence uprights 05.

[0049] By using the matching insertion of C-shaped inserts into C-shaped slots, the installation, connection, and disassembly of the fence post 05 and the standardized fence panels can be made more convenient, faster, and simpler. Moreover, its C-shaped structure can effectively prevent the connection between the fence post 05 and the standardized fence panels from becoming loose.

[0050] The spacing between the fence posts 05 is 1.5-1.8m. The spacing between the fence posts 05 can be adjusted according to actual construction needs and the spacing of posts 041 to ensure the structural stability of the entire temporary fence.

[0051] Please see the appendix Figure 1 The other end of the diagonal brace 07 is provided with a counterweight 071, which is set on the ground.

[0052] Preferably, the counterweight 071 can be made of iron blocks, concrete blocks, etc. The weight and quantity of the counterweight 071 can be adjusted according to actual needs to improve the support stability of the diagonal brace 07.

[0053] The angle between the diagonal brace 07 and the ground is 55°-60°. The tilt angle of the diagonal brace 07 can be adjusted according to the actual working conditions to ensure effective support and force transmission.

[0054] Please see the appendix Figure 1 To be continued Figure 5 The installation method of this utility model is as follows:

[0055] Before installation, prepare for construction: measure the spacing of the uprights 041 of the municipal railing 04 (the standard is usually 1.5m), and check the verticality of the uprights 041 (the deviation should be ≤5mm / m to ensure the verticality and stability of the fence uprights 05 after installation).

[0056] The prefabricated clamping clip 02 and connecting clip 03, the shape and size (e.g., radius of curvature) of the U-shaped clip 022 match the shape and size of the upright 041, and the drilling position error at the open end of the U-shaped clip 022 is ≤2mm to ensure the through installation of the type 1 clip 021.

[0057] The specific installation steps are as follows:

[0058] Step 1: Attach the fence post 05 to the outside of the municipal railing 04 and connect it with three spaced clamps 02. The U-shaped brackets 022 of the lower two clamps 02 are 300mm and 800mm above the ground of the sidewalk 06, respectively.

[0059] A type 021 code piece is drilled through the open end of the U-shaped code piece 022 and locked in place by a pair of locking pieces 023. The locking pieces 023 are made of M16 bolts with a torque of 45-50 N·m.

[0060] Step 2: Install a clamp 02 200mm below the top of the pole 041. The installation method is the same as in Step 1, and will not be repeated here.

[0061] Install the connecting bracket 03 on the clamp 02. Before installing the locking component 023, pass the pre-drilled hole on the closed end of the connecting bracket 03 through the open end of the U-shaped bracket 022, then install the gasket 024 and the locking component 023, and tighten the locking component 023.

[0062] Insert one end of the diagonal brace 7 into the open end of the connecting bracket 03. The connecting bracket 01 can be rotated using an M20 screw and its matching nut. The M20 screw passes through one end of the diagonal brace 7 and the open end of the connecting bracket 03. After rotating and adjusting the angle of the diagonal brace 7, tighten the nuts at both ends so that the diagonal brace 7 forms a 60° angle with the ground. Fix the other end of the diagonal brace 7 to the ground using an expansion bolt (M12×100mm).

[0063] When encountering sloping sections, the inclination angle of the diagonal brace 07 can be adjusted to 55°-65° according to the slope angle, and a bottom counterweight 071 can be added (the counterweight 071 is preferably 100kg / set) to ensure the effective support and force transmission of the diagonal brace 07.

[0064] Step 3: Insert the standardized fence panels into the C-shaped slots of the fence posts 05 using C-shaped clips, and secure them with M8 bolts (the preferred spacing of the M8 bolts is 500mm) to ensure a reliable connection between the standardized fence panels and the fence posts 05. The standardized fence panels and fence posts 05 are assembled to form a temporary fence.

[0065] When the spacing of the uprights 041 of the municipal railing 04 is non-standard (e.g., 1.8m), an additional railing upright 05 can be added between adjacent railing uprights 05 as an intermediate auxiliary upright and fixed in parallel with double U-shaped hoops to avoid problems with the stability and structural strength of the entire temporary fence due to excessive spacing of the railing uprights 05. The size of the standardized railing panels is adjusted according to the spacing between the intermediate auxiliary upright and the railing upright 05.

[0066] This utility model utilizes the uprights of municipal railings as a supporting foundation and achieves rapid assembly and disassembly of temporary barriers through a modular structure. It solves the problems of severe sidewalk damage, low material turnover, and low construction efficiency in existing technologies, thus achieving the goals of green construction and cost control.

[0067] Taking a certain Fudi project as an example, compared with traditional temporary fencing, this utility model reduces the basic construction cost by 82% (saving 680 yuan per linear meter); increases material turnover revenue by 120% (calculated based on 10 turnovers); technical indicators: the wind load resistance of the temporary fencing is ≥0.55kN / ㎡ (meeting the requirements of GB 50009-2012), and the installation time is shortened by 67% (6m fencing installation only takes 1.3 hours); social value: avoids damage to sidewalks, reduces construction waste emissions by 3.2t / 100m, and maintains a sidewalk traffic rate of over 85% during construction.

[0068] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
