Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a prefabricated water-retaining sill for elevator openings. Background Technology

[0002] To ensure the safety of elevator construction, water barriers are widely used at elevator shaft openings. These barriers prevent water from entering the elevator shaft, protect the lifespan of electrical circuits, avoid contamination of the elevator shaft walls, and extend the elevator's service life.

[0003] However, traditional water-retaining sills are generally cast together with the main structure using concrete. Since the water-retaining sills cannot be disassembled, they need to be removed during the interior decoration construction, which affects the construction progress. At the same time, the elevator opening lacks protective measures, which makes it easy for construction workers to fall, affecting construction safety. These issues need to be improved. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a prefabricated water-retaining sill for elevator openings, which can improve construction progress and construction safety.

[0011] In a preferred embodiment, the present invention can be further configured such that: the fastener includes a locking tube, a clamp, and a baffle; the locking tube is sleeved on the column and rotatably connected to the column; the clamp is used to tighten the crossbeam; and the baffle is disposed on the outer wall of the crossbeam and is used to clamp the two sides of the clamp.

[0012] In a preferred embodiment, the present invention can be further configured such that: both ends of the crossbeam are provided with pads that abut against the sides of the elevator opening, and the pads are provided with screws threaded to the crossbeam.

[0013] In a preferred embodiment, the present invention can be further configured such that a protective net is provided between a pair of the columns.

[0014] In a preferred embodiment, the present invention can be further configured such that: the protective net includes multiple mesh panels, the mesh panels are arranged in a long strip shape, and adjacent mesh panels are rotatably connected by hinges, and the mesh panels are stacked together after being folded.

[0015] In a preferred embodiment, the present invention can be further configured as follows: multiple locking rings are rotatably connected to the column, the locking rings are provided with L-shaped locking hooks, the mesh is provided with locking holes for the locking hooks to pass through, and after the mesh slides down, the vertical section of the locking hooks hooks onto the surface of the mesh.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 , Figure 2 As shown, a prefabricated water-retaining sill for elevator openings includes a concrete base 1, embedded bolts 2, columns 3, beams 4, and fasteners 5.

[0026] like Figure 1 , Figure 2 As shown, the concrete base 1 is elongated and hollow inside to reduce its weight and facilitate disassembly, assembly, and transportation. The concrete base 1 is located at the elevator opening, and the gaps at both ends and the bottom are smoothed with waterproof mortar.

[0027] like Figure 1 , Figure 2 As shown, the pre-embedded bolts 2 are vertically installed at both ends of the upper surface of the concrete base 1, and the columns 3 are vertically installed at both ends of the concrete base 1, and are respectively threaded to a pair of pre-embedded bolts 2. The crossbeam 4 is horizontally installed between a pair of columns 3, and both ends of the crossbeam 4 are provided with pads 41 that abut against both sides of the elevator opening. The pads 41 are provided with screws 42 that are threaded to the crossbeam 4.

[0028] like Figure 1 , Figure 2 As shown, the fastener 5 is used to fix the crossbeam 4 to the column 3. The fastener 5 includes a locking tube 51, a clamp 52 and a baffle 53.

[0029] like Figure 1 , Figure 2 As shown, the locking tube 51 is sleeved on the column 3 and rotatably connected to the column 3. The clamp 52 is used to clamp the crossbeam 4. The baffle 53 is set on the outer wall of the crossbeam 4 and is used to clamp the two sides of the clamp 52.

[0030] When a water-retaining sill needs to be installed at the elevator opening, the concrete base 1 is placed inside the elevator opening. Then, the gaps at both ends and the bottom of the concrete base 1 are smoothed with waterproof mortar, and the concrete base 1 is fixed to the structural base plate to ensure that construction water will not flow into the elevator shaft. At the same time, the water-retaining sill can be easily removed and reused during the later fine decoration, thus improving the construction progress.

[0031] Then, the column 3 is rotated and fixed onto the pre-embedded bolt 2 to achieve the installation of the column 3. Then, the locking tube 51 is rotated so that the locking tube 51 faces inward. Then, the crossbeam 4 is tightened and fixed using the clamp 52, and the baffle 53 on the crossbeam 4 clamps the two sides of the clamp 52 to achieve the installation and fixation of the column 3 and the crossbeam 4.

[0032] Then rotate the pad 41 so that it contacts and presses against both sides of the elevator opening, thus fixing the beam 4 in place. This allows the column 3 and the beam 4 to form a quick-assembly guardrail on the water-retaining sill, which can protect the construction elevator opening, prevent construction workers from falling, and improve construction safety.

[0033] like Figure 1 , Figure 2 As shown, a protective net 6 is provided between a pair of uprights 3. The protective net 6 includes multiple net panels 61. The net panels 61 are arranged in a long strip shape, and adjacent net panels 61 are connected by hinges. The net panels 61 are folded and stacked together.

[0034] like Figure 1 , Figure 2 As shown, a multi-layered locking ring 31 is rotatably connected to the column 3, and an L-shaped locking hook 32 is provided on the locking ring 31. The mesh 61 is provided with a locking hole 62 for the locking hook 32 to pass through, and after the mesh 61 slides down, the vertical section of the locking hook 32 hooks tightly onto the surface of the mesh 61.

[0035] like Figure 1 , Figure 2 As shown, the vertical section of the bottommost locking hook 32 is threaded with a fixing pin 33, and the mesh 61 is provided with a fixing hole 63 for the fixing pin 33 to be inserted.

[0036] After the water-retaining sill is installed, the protective net 6 is taken out and unfolded. Then, the locking ring 31 is rotated so that the locking hooks 32 on the locking ring 31 face outwards. The corresponding locking hooks 32 are then inserted through the locking holes 62 on each mesh panel 61. The entire protective net 6 is then moved downwards so that the locking hooks 32 hook the mesh panel 61. Finally, the fixing pin 33 is rotated and inserted into the fixing hole 63 to realize the installation and fixation of the protective net 6, thereby improving the protective capability of the entire guardrail structure.

[0037] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
