Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a temporary barrier railing for barrier-free passageways. Background Technology
[0002] In the temporary protective structures used at construction sites, steel pipes are used to tie the bottom of the guardrails on both sides to the ground to increase their stability. The spacing between the steel pipes is generally about 4 to 6 meters. The steel pipes protrude about 8 centimeters above the ground, posing a slip and fall hazard to pedestrians, especially obstructing the movement of carts or small machinery, requiring the installation of additional formwork before passage is possible. Finding a solution that allows passage through temporary protective passages without the need for formwork remains an ongoing problem. Utility Model Content
[0003] To address the issue of ensuring smooth passage through temporary protective walkways without the need for formwork, this invention provides a barrier-free temporary protective railing. In constructing the temporary protective railing, a floor-mounted base plate replaces the steel pipes as tie rods. Connecting components are used to connect the uprights of the temporary railing to the base plate, which acts as the tie rods. This solves the problem of obstructing the ground surface and hindering passage caused by the steel pipe tie rods used to stabilize the temporary railing.
[0004] A temporary barrier for barrier-free passageways includes two barriers on both sides of the passageway. Each barrier includes uprights and horizontal bars. Multiple uprights are evenly spaced along the passageway direction, and multiple horizontal bars are evenly spaced along the vertical direction of the uprights. The uprights and horizontal bars are connected by fasteners. The barrier also includes a floor panel and connecting components. Two uprights symmetrically positioned on both sides of the passageway are respectively connected to two connecting components at the ends away from the passageway. The floor panel covers the passageway, and both ends of the floor panel are bolted to the ground near the ends of the two connecting components.
[0005] Furthermore, the connecting component includes a base plate and a core rod. The end of the base plate away from the channel is fixedly connected to the core rod, and the upright is sleeved outside the core rod. The end of the base plate near the channel and the end that is attached to the floor are pressed and fixed to the ground by bolts.
[0006] Furthermore, the upright is a φ48*2.8 steel pipe, and the core rod is a φ40*2.8 steel pipe.
[0007] Furthermore, the bottom plate is welded and fixedly connected to the core rod at the end away from the channel.
[0008] Furthermore, the bottom plate is provided with a threaded hole near the channel end, and a nut is welded on the threaded hole. The bolt passes through the threaded hole and the nut to press the bottom plate near the channel end and the end that is attached to the floor onto the ground.
[0009] Furthermore, both the base plate and the floor plate are grounding flat irons, the nuts are M10 nuts, and the bolts are 30~40mm long M10 bolts.
[0010] The beneficial effects of this utility model are as follows:
[0011] (1) In this utility model, the steel pipe tie rods of the stable guardrail are replaced with floor-mounted ones, which significantly reduces the height of the tie rods protruding from the road, thereby avoiding road obstruction. This solves the problem that road obstructions make it easy for pedestrians to slip and fall, and small vehicles must lay templates to pass. It improves the safety and efficiency of passage and reduces safety hazards.
[0012] (2) This utility model replaces the connecting fasteners of the guardrail uprights and tie rods with connecting components, which further reduces the height of the guardrail against the floor and simplifies the guardrail construction operation, improves the efficiency of the passage guardrail construction, and helps to solve the problem of passage obstruction caused by passage obstacles.

[0024] A temporary barrier for accessible passageways, such as Figures 1 to 4 As shown, two guardrails are installed on both sides of the passage 5. The guardrails include uprights 1 and crossbars 2. Multiple uprights 1 are evenly spaced along the passage direction, and multiple crossbars 2 are evenly spaced along the vertical direction of the multiple uprights. The uprights 1 and crossbars 2 are connected by fasteners. The guardrail is characterized by further including a floor panel 3 and connecting components 4. Two uprights 1 at symmetrical positions on both sides of the passage 5 are respectively sleeved and connected to two connecting components 4 at the ends away from the passage. The floor panel 3 covers the passage 5, and the two ends of the floor panel 3 are respectively pressed and fixed to the ground by bolts 6 at the ends of the two connecting components 4 near the passage.
[0025] This invention replaces steel pipes with floor-mounted panels as tie rods, and replaces fasteners with connecting components to connect the guardrail posts to the floor-mounted panels. The connecting components firmly press the floor-mounted panels onto the passageway floor, preventing obstruction of passage and allowing normal passage without the need for formwork. It solves the problem of blocked passageways caused by steel pipe tie rods used to stabilize temporary guardrails. This improves safety and efficiency of passage, and reduces safety hazards.
[0026] Furthermore, such as Figures 1 to 4 As shown, the connecting assembly 4 includes a base plate 41 and a core rod 42. The end of the base plate 41 away from the channel is fixedly connected to the core rod 42. The upright 1 is sleeved on the outside of the core rod 42. The end of the base plate 41 near the channel is pressed and fixed to the ground by bolts 6. Further, the upright 1 is a φ48*2.8 steel pipe, and the core rod 42 is a φ40*2.8 steel pipe.
[0027] Furthermore, such as Figures 1 to 4 As shown, the base plate 41 is welded and fixedly connected to the steel pipe at the end away from the channel. Furthermore, a threaded hole is provided at the end of the base plate 41 near the channel, and a nut 7 is welded to the threaded hole. A bolt 6 passes through the threaded hole and the nut to press the end of the base plate 41 near the channel and the end of the floor 3 against the ground.
[0028] Furthermore, such as Figures 1 to 4 As shown, the base plate 41 and the floor plate 3 are both grounding flat irons, the nut is an M10 nut, and the bolt is a 30~40mm long M10 bolt.
