Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of expansion joint processing, and particularly relates to a drainage processing structure for an expansion joint of a building connecting an outdoor corridor. Background Art
[0002] In existing building structures, expansion joints are usually provided at the connection between the second-floor gate of the electrolysis plant and the outdoor road to accommodate the expansion and contraction requirements of the building due to temperature changes or foundation settlement. However, the traditional expansion joint treatment method has some significant defects, especially in industrial environments such as electrolysis plants, which may lead to serious production safety problems. The traditional expansion joint design allows the top surface of the expansion joint to remain flush with the road and indoor floor to ensure the smooth passage of process vehicles. However, this design has obvious shortcomings when encountering extreme weather conditions such as strong winds and heavy rain. Rainwater easily flows along the road, crosses the top surface of the expansion joint, and then flows into the interior of the plant, which not only damages the production equipment, but also may endanger the safety of the staff. In order to solve this problem, it is usually necessary to modify the expansion joint. The conventional method of modification includes removing the foam board in the original ground and expansion joint, and re-casting the bottom surface with fine stone concrete to ensure flatness. Subsequently, a thin steel plate with a shape of "J" is installed at the expansion joint and fixed to the original concrete slab, and finally covered with a steel cover to allow the passage of process vehicles.
[0003] Although this modification method solves the flatness problem of expansion joints to a certain extent, it still has the following disadvantages:
[0004] 1) Drainage problem: The design of the steel cover is not conducive to the rapid drainage of rainwater. When there is heavy rainfall, rainwater easily accumulates and overflows the steel cover, and finally flows into the factory building.
[0005] 2) Load-bearing capacity: The strength of the "J"-shaped thin steel plate and steel cover plate is insufficient to withstand the heavy load of process vehicles for a long time, which can easily lead to deformation and affect the normal passage of vehicles.
[0006] 3) Durability and maintenance costs: Steel cover plates and I-shaped steel plates are easily damaged under long-term vehicle rolling and require frequent repairs and replacements, which not only shortens their service life but also increases maintenance costs.
[0007] In view of these problems existing in the prior art, there is an urgent need to develop a new expansion joint drainage treatment structure that can not only ensure the safe and smooth passage of process vehicles, but also effectively prevent rainwater from flowing into the factory building, thereby improving the overall safety and practicality. Utility Model Content
[0008] The purpose of the utility model is to overcome the above-mentioned defects and proposes a drainage treatment structure for expansion joints of buildings connecting outdoor corridors, which solves the problems existing in the prior art such as poor drainage of expansion joints, low material strength at the expansion joints, easy deformation and damage, poor durability, and high maintenance costs.
[0009] The specific technical solutions are as follows:
[0010] A drainage treatment structure for expansion joints of building-connected outdoor corridors, wherein both sides of the expansion joint are cast with concrete, and a first step surface and a second step surface facing the expansion joint and sinking in sequence are symmetrically arranged on both sides of the expansion joint, and the second step surface is connected to the expansion joint; a drainage ditch plate is arranged along the first step surface and the second step surface, and both sides of the drainage ditch plate correspond to the first step surface and are flush with the road surface, and the middle of the drainage ditch plate is flush with the second step surface; a corresponding steel grille cover plate is placed in the drainage ditch plate, and the top surface of the steel grille cover plate is flush with the road surface.
[0011] Furthermore, the drainage ditch plate is formed by fully welding or folding steel plates.
[0012] Furthermore, the height of the first step surface relative to the road surface is smaller than the height of the second step surface relative to the first step surface.
[0013] Furthermore, the width of the second step surface is not less than the width of the first step surface.
[0014] Furthermore, the width of the second step surface is 2-3 times the width of the expansion joint.
[0015] Furthermore, the width of the second step surface is 1-3 times the width of the first step.
[0016] Furthermore, the steel grille cover plate includes two parallel angle steels and a plurality of round steel bars, and the round steel bars are welded between the inner angles of the two parallel angle steels at equal intervals.
[0017] Furthermore, the length of the angle steel is 1 meter, and the interval between the round steel bars is 50 mm.
[0018] Furthermore, the drainage ditch plate and the steel grille cover plate are provided with an anti-rust paint layer and a blending paint layer in sequence from the inside to the outside.
[0019] Furthermore, the first step surface and the second step surface are made of high-strength non-shrinkage concrete with a thickness of 20 mm.
[0020] Compared with the existing technology, the beneficial effects of the utility model are:
[0021] 1. The utility model effectively solves the problem that ordinary expansion joints are not conducive to drainage, and can prevent rainwater from overflowing the expansion joints and entering the factory building even when the rainwater flow is large.

[0029] Example
[0030] like Figure 1As shown, the utility model relates to a drainage treatment structure of an expansion joint 5 of a building connecting an outdoor corridor, including concrete slabs 4 cast by concrete on both sides of the expansion joint 5, which constitute the foundation of the drainage treatment structure. Before implementing the structure of the utility model, it should be ensured that the foundations on both sides of the expansion joint 5 are reinforced by concrete casting to ensure the stability of the drainage treatment structure foundation. A first step surface 6 and a second step surface 7 are symmetrically arranged on both sides of the expansion joint 5, which are successively sunken toward the expansion joint 5, wherein the second step surface 7 is directly connected to the expansion joint 5. The first step surface 6 and the second step surface 7 are both planes, and the transition between the first step surface 6 and the second step surface 7 is a right-angle transition. Furthermore, in order to ensure that the first step surface 6 and the second step surface 7 are firm, stable and durable as supporting surfaces, the first step surface 6 and the second step surface 7 are formed of high-strength non-shrinkage concrete with a thickness of 20 mm; specifically, the original concrete slabs 4 on both sides are firstly chiseled along the expansion joint 5, grooved into a folded tooth shape, and the first step surface 6 and the second step surface 7 are formed of high-strength non-shrinkage concrete with a thickness of 20 mm.
[0031] The drainage ditch plate 3 is laid along the first step surface 6 and the second step surface 7. The two sides of the drainage ditch plate 3 are closely attached to the first step surface 6 and are flush with the road surface, while the central part is attached to the second step surface 7. A corresponding steel grille cover plate is provided in the central position of the drainage ditch plate 3, and its top surface is also flush with the road surface, ensuring the flatness and aesthetics of the overall structure. The drainage ditch plate 3 is intended to form a drainage channel, and the steel grille cover plate serves as the internal support structure of the drainage ditch plate 3, which is flush with the road surface and ensures the stability of vehicle traffic.
[0032] In the production of the gutter plate 3, the gutter plate 3 can be made by welding or folding steel plates. When welding is used, a narrow steel plate is used for the first step surface 6, which is the same height as the first step surface 6 and is kept flush with the road surface; a wide steel plate is used for the second step surface 7, which spans the two second step surfaces 7 and is fully welded to the narrow steel plate on the first step surface 6 through another narrow steel plate, ensuring that the gutter plate 3 and the groove formed by the step surface fit tightly. If the folding method is used, it is necessary to ensure that the gutter plate 3 is completely fitted with the groove formed by the first step surface 6 and the second step surface 7, specifically by trimming the edges and corners of the first step surface 6 and the second step surface 7 to fit the gutter plate 3 and avoid any gaps.
[0033] like Figure 2As shown, the steel grating cover plate is composed of two groups of parallel angle steels 1 and a plurality of round steel bars 2, and the round steel bars 2 are welded between the inner corners of the two groups of parallel angle steels 1 at equal intervals. Specifically, the angle steels 1 are arranged in parallel with the inner corners facing each other, and the round steel bars 2 are welded between the inner corners of the angle steels 1 at equal intervals of 50 mm. The end angles of the angle steels 1 constitute the end angles of the upper part of the steel grating cover plate, which remain flush with the road surface, while the sides of the angle steels 1 serve as supporting edges. The gutter plate 3 not only serves as a gutter, but also a force-bearing support structure for the steel grating cover plate. The round steel bars 2 act as a grid, forming a space together with the gutter plate 3 and the angle steels 1, allowing rainwater to flow in and out smoothly.
[0034] In order to form a stable expansion joint 5 supporting structure that can withstand heavy loads and is not easily deformed, the height of the first step surface 6 relative to the road surface should be less than the height of the second step surface 7 relative to the first step surface 6. In addition, the width of the second step surface 7 should not be less than the width of the first step surface 6. Specifically, the width of the second step surface 7 should be 2 to 3 times the width of the expansion joint 5, and specifically in this embodiment, 2 times can be selected; and the width of the second step surface 7 is 1 to 3 times the width of the first step, and specifically in this embodiment, 1.5 times can be selected.
[0035] The further specific implementation process based on the above scheme includes:
[0036] (1) Prepare the “Organizational Measures, Technical Measures and Safety Measures for the Dismantling and Installation of Telescopic Devices”.
[0037] (2) Provide technical and safety briefings to on-site workers, ensure that key management personnel and special operations personnel are certified, and that all workers and on-site supervisors obey the unified command and management of the construction manager.
[0038] (3) Remove the original concrete slab 4, cut grooves into a tooth shape, and use high-strength non-shrinkage concrete to smooth all the grooved surfaces to form the first step surface 6 and the second step surface 7. Then weld narrow steel plates and wide steel plates in the groove to form the drainage ditch plate 3. Use two L50*5 angle steels 1 and round steel bars 2 to weld and make a grille cover plate, which is laid in the groove with the top surface flush with the road surface and the spacing between round steel bars is 50mm. All steel structures need to be rust-proofed before construction, and painted with two coats of anti-rust paint and two coats of blending paint.
[0039] Through the implementation of this embodiment, process vehicles at the factory door can pass smoothly when passing through the expansion joint 5. In case of bad weather such as strong winds and heavy rain, rainwater can smoothly flow into the groove of the expansion device and be discharged outside the factory. In addition, the expansion device has high durability. Even if part of the steel grille cover is damaged, it is easy to quickly disassemble, replace or correct it due to its short design, and the maintenance time is short. In addition, there is no need to block the road during the construction process, which does not affect the passage of vehicles. The drainage problem and the fragility problem of the expansion joint 5 are fundamentally solved, creating favorable conditions for safe production in the factory.
[0040] The above description is only a preferred feasible embodiment of the present invention and is not intended to limit the scope of the patent application of the present invention. All equivalent changes, equivalent substitutions or modified changes performed within the technical spirit and principles suggested by the present invention should be included in the scope of patent protection covered by the present invention.
