Description

Technical Field

[0001] This invention relates to the field of building construction, and in particular to a factory floor expansion joint. Background Technology

[0002] Floor expansion joints are typically 200mm wide. The conventional method involves pre-growing a 5-10cm wide, 2cm deep concrete groove in the floor, leveling it with unequal-sided angle steel, and then directly laying a single 8-16mm thick stainless steel plate on top of the angle steel, securing it with adhesive at both ends. This method has poor load-bearing capacity; under frequent heavy loads such as forklift traffic, the stainless steel plate is prone to warping and curling. Repairing floor expansion joints usually involves chiseling out the concrete, welding a cover plate to the exposed reinforcing steel, and then filling the gap with grout. This method not only causes color differences in the concrete at the expansion joint but also, since factory floor slabs are typically 120-180mm thick, chiseling makes the concrete even thinner, reducing the floor's load-bearing capacity and leading to repeated repairs during later use.

[0003] Therefore, it is necessary to invent a factory floor expansion joint to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a factory floor expansion joint to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a factory floor expansion joint, including a newly built factory expansion joint and an old factory renovation expansion joint. The newly built factory expansion joint includes a first expansion joint and I-beam bodies embedded in the floor slabs on both sides of the first expansion joint. The I-beam bodies and the first expansion joint are perpendicularly distributed, and one end of the I-beam body extends out of the first expansion joint. An I-beam base is provided inside the I-beam body. The web of the I-beam base has a groove, and the flange of the I-beam body is locked in the groove. A first hot-dip galvanized plate is provided at the top of each of the two I-beam bases. A first expansion joint is provided between the two first hot-dip galvanized plates. The first expansion joint is filled with a rubber and plastic strip. A gap is provided between the two first hot-dip galvanized plates and the sidewall of the first expansion joint. The gap is filled with a first sealant.

[0006] Preferably, the expansion joint in the old factory renovation includes a second expansion joint, with angle steel provided on both sides of the second expansion joint, and square ribs of the same side length welded to both angle steels.

[0007] Preferably, chemical anchors are provided between the two angle steels and the inner wall of the second expansion joint at their respective positions. Multiple chemical anchors are provided and are evenly distributed along the long side of the angle steels.

[0008] Preferably, both angle steels are L-shaped, and each angle steel has a second hot-dip galvanized sheet at its top. The length of the two second hot-dip galvanized sheets is greater than the length of the angle steel. Extension grooves are provided on both sides of the top of the second expansion joint, and the second hot-dip galvanized sheets are placed inside the extension grooves. A second expansion joint is provided between the two second hot-dip galvanized sheets.

[0009] Preferably, the interior of the second expansion joint is provided with a rubber and plastic strip, and an expansion bolt is provided between the bottom ends of the two second hot-dip galvanized plates and the extension groove. The expansion bolt is located on the side of the bottom end of the second hot-dip galvanized plate away from the second expansion joint. Multiple expansion bolts are provided and distributed along the long side of the second hot-dip galvanized plate.

[0010] Preferably, a gap is reserved between the second hot-dip galvanized sheet and the angle steel, and the gap is filled with grout. A gap is also reserved between the inner wall of the second hot-dip galvanized sheet and the second expansion joint, and a second sealant is provided in the gap.

[0011] Preferably, rock wool is provided at the bottom of the I-beam base, an anti-slip pad is provided between the I-beam body and the I-beam base, and an aluminum alloy cover plate is provided at the bottom of the first expansion joint.

[0012] Preferably, the first hot-dip galvanized sheet is configured as a serrated shape.

[0013] This invention also includes a method for constructing expansion joints on factory floors, comprising a method for constructing expansion joints in newly built factory buildings and a method for constructing expansion joints in renovated old factory buildings. The method for constructing expansion joints in newly built factory buildings includes the following steps:

[0014] Step 1: Embed multiple I-beam bodies on the floor slabs on both sides of the first expansion joint. The I-beam bodies are 680mm long, 5mm thick, spaced 700mm apart, and extend 80mm beyond the first expansion joint. Step 2: Pour the floor slab concrete. Step 3: Connect the I-beam base to the I-beam body. Cut grooves 20mm high and 40mm deep in the web of the I-beam base to hold the embedded I-beam flanges. Use the gaps in the grooves to level the I-beam base and weld it firmly. Step 4: Lay a 2cm thick, serrated first hot-dip galvanized sheet, 2cm narrower than the first expansion joint, on the I-beam base. Level it with the ground on both sides. Weld the bottom edge of the first hot-dip galvanized sheet to the I-beam base without damaging the upper galvanized layer. Step 5: Fill the gaps on both sides of the first hot-dip galvanized sheet with adhesive for 1cm.

[0015] The preferred construction method for expansion joints in the renovation of old factory buildings includes the following steps: Step 1: Select 80mm wide unequal angle steel. The height of the angle steel is determined according to the thickness of the floor slab. Weld square ribs with the same side length as the angle steel onto the angle steel. The square ribs are 4mm thick and distributed at 500mm intervals.

[0016] Step 2: Fix the angle steel with M12 chemical anchors at 300mm intervals, 2cm from the bottom edge of the floor slab, with the anchors 50mm from the top of the angle steel. Step 3: Set the second hot-dip galvanized sheet in a sawtooth shape, with the width of the second hot-dip galvanized sheet increased by 5cm on each side compared to the second expansion joint. Drive expansion bolts into the extension groove of the structural floor slab and weld them to the bottom edge of the second hot-dip galvanized sheet to ensure that the galvanized layer on the upper surface of the second hot-dip galvanized sheet is not damaged. Step 4: Leave a 1cm structural gap, fill it with grout, and fill the bottom of the second hot-dip galvanized sheet. Step 5: Leave a 1cm gap on both sides of the second hot-dip galvanized sheet and apply structural adhesive.

[0017] The technical effects and advantages of this invention are as follows:

[0018] 1. The new floor expansion joint process replaces the original method of only stainless steel cover plates with two hot-dip galvanized plates, I-beams, angle steel, and rock wool materials. This optimizes the expansion joints of the factory floor, significantly improves their durability, and solves common problems such as warping and curling caused by forklifts. The implementation has achieved good construction results.

[0019] 2. Two construction methods can be used to address the actual needs of new factory buildings and renovations of old factory buildings, saving materials, improving efficiency, and effectively enhancing the load-bearing capacity of expansion joints. This greatly benefits the later use of factory projects, reduces material waste and rework, improves the appearance of the ground, meets the concept of green development, and has promotional value.
