Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and more specifically, it relates to a concrete joint baffle that prevents leakage. Background Technology

[0002] Leak-proof concrete joint baffles are key waterproof components that are pre-embedded in concrete construction joints, settlement joints, or expansion joints. Their core function is to extend the water penetration path through physical means and form a water-blocking barrier by utilizing the density of the material itself.

[0003] According to application number CN201922137058.1, a flame-retardant rubber waterstop includes a waterstop body with a through pipe connected to the middle of the waterstop body. Two waterstop baffles are provided on both sides of the waterstop body near the through pipe, and the surfaces on both sides between the two waterstop baffles form a waterstop zone. A flame-retardant layer is formed inside the waterstop zone near its outer surface. This invention provides a flame-retardant layer in both the waterstop zone and the extension zone. The flame-retardant effect is achieved by filling the flame-retardant pores inside the flame-retardant layer with carbon dioxide gas. When the surface of the rubber tourniquet is burned to the flame-retardant layer, the internal carbon dioxide gas will escape, preventing further combustion. This invention also includes a shaping rod installed inside the through pipe and a support plate installed inside the waterstop baffles to prevent deformation of the through pipe and waterstop baffles due to prolonged concrete compression.

[0004] Based on the above, the existing anti-seepage concrete joint baffles are usually made by joining two baffles together and then welding them together with a welding machine, which is a cumbersome operation and affects work efficiency. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a concrete joint baffle to prevent leakage. This solves the problem that existing concrete joint baffles typically require two baffles to be joined together and welded using a welding machine, a process that is cumbersome and inefficient.

[0006] The purpose and effect of this utility model of a seepage-proof concrete joint baffle are achieved by the following specific technical means: A leak-proof concrete joint baffle includes a connecting column, concrete baffles, connecting slots, extrusion plates, an extrusion mechanism, and a limiting mechanism. Two concrete baffles are provided, each inserted into the inner side of the connecting column. Two connecting slots are provided, each located on the inner side of the connecting column and slidably connected to one of the two concrete baffles. Two extrusion plates are provided, each slidably connected to the inner side of the connecting column. The extrusion mechanism is located on the inner side of the connecting column. The limiting mechanism is located at the upper end of the connecting column.

[0007] Furthermore, the extrusion mechanism also includes: a first extrusion block, a sliding column, and a second extrusion block; the first extrusion block is provided in two sets, and the two sets of first extrusion blocks are respectively fixedly connected to the outside of the two extrusion plates; the sliding column is provided in two sets, and the two sliding columns are slidably connected to the inside of the connecting column; the second extrusion block is provided in two sets, and the two sets of second extrusion blocks are respectively fixedly connected to the outside of the two sliding columns.

[0008] Furthermore, the extrusion mechanism also includes: an extrusion threaded shaft, operating bolts, limiting slots, and tension springs; two extrusion threaded shafts are provided, both of which are rotatably connected to the inner side of the connecting column, and the extrusion threaded shafts are threadedly connected to the sliding column; two operating bolts are provided, each fixedly connected to the upper end face of the extrusion threaded shaft; two sets of limiting slots are provided, each set of limiting slots being opened on the outer side of the two operating bolts; two sets of tension springs are provided, one end of each set of tension springs being fixedly connected to the outer side of the two extrusion plates, and the other end of each set of tension springs being fixedly connected to the inner side of the connecting column.

[0009] Furthermore, the limiting mechanism includes: a sliding box and a positioning ball groove; there are two sliding boxes, both of which are slidably connected to the inner side of the upper end of the connecting column; there are two positioning ball grooves, which are respectively opened at the lower end of the two sliding boxes.

[0010] Furthermore, the limiting mechanism also includes: positioning blocks and positioning compression springs; there are two positioning blocks, both of which are slidably connected to the inner side of the connecting column; there are two positioning compression springs, the upper ends of which are respectively fixedly connected to the outer side of the two positioning blocks, and the other ends of which are fixedly connected to the inner side of the connecting column.

[0011] Furthermore, the limiting mechanism also includes: a limiting plug and a limiting compression spring; there are two limiting plugs, which are slidably connected to the inner sides of the two sliding boxes respectively; there are two limiting compression springs, one end of which is fixedly connected to the outer side of the two limiting plugs respectively, and the other end of which is fixedly connected to the inner side of the two sliding boxes respectively.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention simplifies the installation of concrete baffles through the design of an extrusion mechanism. After the concrete baffle is inserted into the connecting slot, rotating the operating bolt causes the second extrusion block to slide under the threaded connection between the extrusion threaded shaft and the sliding column. The sliding of the second extrusion block, through the first extrusion block, compresses the extrusion plate, thus pressing the concrete baffle tightly against the connecting slot. This simple operation improves work efficiency and reduces labor intensity. The invention also includes a limiting mechanism to restrict the operation bolt. After the operation bolt is rotated, the limiting insert, under the action of the limiting compression spring, inserts into the limiting slot, preventing the operation bolt from reversing. By pushing the sliding box, the limiting insert disengages from the limiting slot, allowing the operation bolt to be reversed and the concrete baffle to be disassembled, thus improving safety. In summary, this mechanism facilitates the installation of concrete baffles and limits the operation bolt, improving work efficiency, reducing labor intensity, and enhancing safety.

[0024] The extrusion mechanism further includes: a first extrusion block 401, a sliding column 5, a second extrusion block 501, an extrusion threaded shaft 6, an operating bolt 601, a limiting slot 602, and a tension spring 7; two sets of the first extrusion blocks 401 are provided, and the two sets of first extrusion blocks 401 are respectively fixedly connected to the outer sides of the two extrusion plates 4; two sliding columns 5 are provided, and the two sliding columns 5 are slidably connected to the inner side of the connecting column 1; two sets of the second extrusion blocks 501 are provided, and the two sets of second extrusion blocks 501 are respectively fixedly connected to the outer sides of the two sliding columns 5; the extrusion threaded shaft 6...
