[0023] Example 1
[0024] This embodiment provides an integral corner protection deformation joint structure based on a heavy-load workshop floor, including a deformation joint, a composite geotextile 1, an angle steel 2, a steel support I 3, a micro-expansive concrete layer 4, a patterned steel plate 5, a steel support II 6, a steel cross brace and a patterned rubber plate 7.
[0025] The expansion joint is arranged on the floor of the heavy-load workshop, and comprises an expansion joint bottom plate and expansion joint side walls located on both sides of the expansion joint bottom plate.
[0026] The composite geotextile 1 is hot-melt bonded to the side wall and bottom plate of the expansion joint to separate the new and old concrete, achieve the purpose of structural deformation and shrinkage, and better prevent the backfill soil layer under the ground from being damaged by upper water penetration. The joints of adjacent composite geotextiles 1 are all hot-melt bonded. In this embodiment, the composite geotextile 1 is a composite geotextile with a two-cloth and one-membrane structure.
[0027] The angle steel 2 is buckled on the corners of the cast-in-place concrete floor on both sides of the deformation joint to protect it and compress the composite geotextile 1 laid on the side wall of the deformation joint. In this embodiment, the angle steel 2 is a galvanized equal-edge angle steel.
[0028] The top of the steel support bracket Ⅰ3 is connected to the side plate of the angle steel 1 located in the deformation joint, and the bottom is connected to the composite geotextile 1 laid on the bottom plate of the deformation joint to support the angle steel 1.
[0029] The micro-expansive concrete layer 4 is filled between the composite geotextile 1, the angle steel 2 and the steel support I 3. In this embodiment, the micro-expansive concrete layer 4 is cast by impermeable concrete mixed with 8% expansion agent. Due to the shrinkage of the concrete floor on both sides, the micro-expansive concrete layer 4 is cast to compensate for the shrinkage and prevent the floor from shrinking too much.
[0030] The patterned steel plate 5 covers the micro-expansive concrete layer 4. On the one hand, it covers and protects the micro-expansive concrete surface layer. On the other hand, its overall flat plate structure is more conducive to the transmission of ground loads, making the deformation joints more evenly stressed. The patterned steel plate 5 is provided with exhaust holes.
[0031] The steel bar support II6 is inserted in the micro-expansion concrete layer 4, with the top connected to the patterned steel plate 5 and the bottom connected to the composite geotextile 1 laid on the deformation joint bottom plate. Since the steel bar support I3 and the steel bar support II6 only play a fixed support role, and the angle steel 2 and the patterned steel plate 5 are both stamping components without pull-out requirements, round steel can be used to ensure that the steel bar support is better inserted into the concrete. In this embodiment, the steel bar support II6 is an inverted V-shaped structure.
[0032] Multiple steel bar cross braces are arranged at equal distances along the length direction of the deformation joint to compress the patterned steel plate 5; the two ends of each steel bar cross brace are respectively connected to the angle steels 2 on both sides. The steel bar cross braces firmly fix the patterned steel plate 5 and the angle steel 2, thereby making the overall structure more stable and preventing secondary sliding.
[0033] The patterned rubber sheet 7 is pasted and covered on the patterned steel plate 5 and the steel bar cross brace by adhesive, and serves as a protective plate for the patterned steel plate 5. Due to the long-term rolling and impact of ground vehicles, in order to prevent the patterned steel plate 5 from being deformed due to long-term fatigue operation, a replaceable patterned rubber sheet 7 is used to protect the patterned steel plate 5. The patterned rubber sheet 7 can slightly protrude from the ground to protect the deformation joint structure.
[0034] Compared with the conventional ground deformation joint structure, the above-mentioned integral corner protection deformation joint structure based on the heavy-load workshop floor can not only protect the corners and partition them, but also the upper vulnerable materials are easy to replace. It is simple and beautiful, easy to operate and efficient in construction. Through this structure, it plays a good supporting and protective role for the concrete on both sides of the deformation joint, eliminating the hidden dangers of the deformation joint corners being damaged by long-term extrusion and difficult to deal with.
[0035] Example 2
[0036] The construction process of the above-mentioned integral corner protection deformation joint structure based on the heavy-load workshop floor is as follows.
[0037] First, the composite geotextile 1 is hot-melt bonded to the inner structure of the deformation joint of the concrete floor in advance, and then the angle steel 2 is buckled on the corners of the cast-in-place concrete floor on both sides for protection. The bottom is welded and fixed by the steel support bracket Ⅰ3, and fixed by pouring micro-expansive concrete. Then, the patterned steel plate 5 with the welded steel support bracket Ⅱ6 is pressed into the poured micro-expansive concrete, and the steel cross brace is installed. Finally, the patterned rubber plate 7 is pasted on the patterned steel plate 5 by adhesive to complete the overall installation of the structure.
[0038] In this embodiment, the composite geotextile 1 is 200 cloth + 400 membrane + 200 cloth, the angle steel 2 is a 50*50*3mm galvanized equilateral angle steel, the steel support I3 and the steel support II6 are made of Φ8 round steel, the patterned steel plate 5 is a 10mm thick Q235 steel plate, and the thickness of the patterned rubber plate 7 is 25mm.
[0039] Before installing the angle steel 2 corner guard, the corners on both sides of the deformation joint should be trimmed and straightened in advance to prevent the angle steel 2 from being deformed during installation. It should be temporarily fixed with square wood, and then the steel support Ⅰ3 below should be welded.
[0040] When pouring, the micro-expansive concrete can be fixed by pouring in layers and sections. When pouring reaches 35mm below the surface layer, stop pouring and smooth the surface layer.
[0041] The width of the patterned steel plate 5 is smaller than the difference between the net width of the deformation joint and the thickness of the angle steels on both sides, which facilitates the pressing of the patterned steel plate 5 into the micro-expansive concrete. The patterned steel plate 5 is welded to the steel support Ⅱ 6 in advance, and then the patterned steel plate 5 welded with the steel support Ⅱ 6 is pressed into the micro-expansive concrete, and the level of the patterned steel plate 5 is adjusted by pulling the wire.
[0042] The patterned steel plate 5 is provided with steel bar cross braces at intervals of 3m along the length direction.
[0043] The above-mentioned integral corner protection deformation joint structure based on the heavy-loaded workshop floor can not only meet the needs of ground deformation joints, but also protect the molding quality of the new and old concrete corners of the ground, and can withstand the passage and rolling of heavy vehicles. The construction and installation are more convenient and the efficiency is greatly improved.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
