Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a subway upper cover gap cover plate structure. Background Art

[0002] The subway roof gap refers to the gap or gap between the subway tracks, platforms, etc. and the surrounding environment. The expansion joint is set to adapt to the deformation of the building caused by factors such as temperature changes and uneven settlement. It can effectively reduce the stress caused by deformation and ensure the safety of the building. Traditional roof expansion joint cover plates are mostly upper inverted beam floating plate structures, but for subway roof expansion joints that need to be backfilled, it has the advantages of simple casting system construction, short construction period, and less wooden formwork consumables.

[0003] However, the inverted beam and floating slab structure is difficult to effectively prevent water erosion. Because the floating slab cannot seal the expansion joint, the water seepage path is between the floating slab and the structural beam at the top of the expansion joint, making it impossible to stop the water flow. Therefore, those skilled in the art have proposed an improved subway roof gap cover structure to address the problems raised in the above background technology. Utility Model Content

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] Next, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, cross-sectional views of device structures may be partially enlarged and not to scale when describing the embodiments of the present invention. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.

[0040] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0041] Example 1

[0042] See also Figures 1-6 As shown, this embodiment is a subway roof gap cover structure, including:

[0043] Structural beams and plates 100 and deformation joints 101 between the structural beams and plates 100;

[0044] The waterproof structure 200 includes an aluminum alloy plate 203 located at the upper end of the structural beam plate 100 and having a V-shaped middle section, a cover plate 1 201 and a cover plate 202 sleeved on the outside of the aluminum alloy plate 203, and an F-shaped waterproof geomembrane 207 clamped on the outer wall of the aluminum alloy plate 203;

[0045] A travel groove 209 is formed inside one end of the cover plate 1 201 , and an insert plate 206 is provided at one end of the cover plate 202 , and one end of the insert plate 206 is slidably inserted into the travel groove 209 ;

[0046] The inner wall of one side of the travel groove 209 is provided with equidistantly distributed corrugated sheets 205, and one end of the corrugated sheet 205 is connected to the insert plate 206;

[0047] The top of the cover plate 1 201 is provided with a top plate 204 covering the top of the cover plate 202. The top of the aluminum alloy plate 203 is provided with grooves 208 distributed at equal intervals.

[0048] Using the waterproof structure 200;

[0049] During installation, the upper end of the structural beam plate 100 is cleaned and kept dry. At the same time, the F-shaped waterproof geomembrane 207 is clamped on the upper and lower ends of the aluminum alloy plate 203. After heat treatment, the outer wall of the waterproof geomembrane 207 is soft and smooth, and adheres to the outer wall of the waterproof aluminum alloy plate 203. At the same time, the hot melt surface adheres to the structural beam plate 100. Then, the cover plate 1 201 and the cover plate 2 202 are clamped on the outside of the structural beam plate 100, and the inner walls of the cover plate 1 201 and the cover plate 2 202 are connected. The waterproof geomembrane 207 adheres to the aluminum alloy plate 203, the structural beam plate 100, and the joints of the cover plate 1 201 and the cover plate 2 202 after cooling, thereby preventing the intrusion of rainwater from the outside. At the same time, the V-shaped aluminum alloy plate 203 facilitates expansion and contraction adjustment. The cover plate structure of the subway cover gap can freely expand and contract with the expansion and contraction caused by factors such as temperature changes and building settlement, thereby maintaining the integrity and stability of the building body and avoiding cracking and deformation.

[0050] When cover plate 1 201 and cover plate 2 202 are installed, cover plate 1 201 and cover plate 2 202 are squeezed or stretched according to the width of the deformation joint 101 between the structural connecting plates, thereby achieving that cover plate 1 201 and cover plate 2 202 effectively cover the outside of the structural beam plate 100 and the aluminum alloy plate 203, thereby improving the protection of the deformation joint 101 when shielding during use. At the same time, the groove 208 is convenient for the staff to cut and position during use, and it is convenient to guide the cutting surface when the aluminum alloy plate 203 is cut and adjusted according to the length of the deformation joint 101.

[0051] Example 2

[0052] See also Figures 1-6 As shown, this embodiment is based on embodiment 1 and also includes:

[0053] as well as;

[0054] The positioning structure 300 includes guide rails 301 fixed on both sides of the lower end of the aluminum alloy plate 203 and adjustment blocks 302 equidistantly distributed below the aluminum alloy plate 203 .

[0055] A slider 304 is provided on the upper end of the adjustment block 302, and the slider 304 is slidably mounted on the outer wall of the guide rail 301;

[0056] The adjusting block 302 has a screw hole 306 formed inside, a screw rod 305 is threadedly installed inside the screw hole 306, a torsion ring 303 is provided at one end of the screw rod 305, and a support block 307 is rotatably installed at one end of the screw rod 305;

[0057] Performing the use of the positioning structure 300;

[0058] When the aluminum alloy plate 203 is installed, the adjustment block 302 slides to adjust the position, and the adjustment position is the two sides and the middle point of the deformation joint 101. The gripping torsion ring 303 drives the screw 305 to rotate, and the screw 305 rotates inside the screw hole 306, thereby realizing the movement of the screw 305 inside the screw hole 306 and driving the support block 307 to move laterally. When the support block 307 fits with the inner wall of the deformation joint 101, the aluminum alloy plate 203 is clamped, and the aluminum alloy plate 203 is clamped in the gap of the structural beam plate 100, thereby realizing the positioning of the aluminum alloy plate 203 during installation, avoiding the aluminum alloy plate 203 from shaking at will, and improving the installation stability when the aluminum alloy plate 203 is used to cover and protect the gap of the subway cover.
