Abstract
Description
Technical Field
[0001] The utility model relates to the field of construction engineering, in particular to a basement floor post-cast belt anti-leakage structure. Background Art
[0002] In the cast-in-place integral reinforced concrete structures of high-rise residential buildings, public buildings and super-long structures, post-cast strips are usually required. Among them, the post-cast strips of the basement floor often leak due to the abundance of groundwater, which increases the cost of later maintenance.
[0003] In order to deal with the water leakage in the post-cast strip of the basement floor, the current anti-leakage structure of the post-cast strip of the basement floor usually sets a left water stop plate on the left wall of the basement, and a right water stop plate on the right wall of the basement, and respectively sets a first segmented water stop plate and a second segmented water stop plate between the left water stop plate and the right water stop plate which are parallel to each other. Both segmented water stop plates are perpendicular to the left water stop plate (or the right water stop plate), the left end face of the first segmented water stop plate is welded to the left water stop plate, the right end face of the second segmented water stop plate is welded to the right water stop plate, and welding is performed on the lower side of the right end face of the first segmented water stop plate and the lower side of the left end face of the second segmented water stop plate, so that the right end face of the first segmented water stop plate is welded to the left end face of the second segmented water stop plate. In this way, it is hoped to ensure that the groundwater under the basement floor cannot leak into the basement through the left water stop plate, the right water stop plate and the two segmented water stop plates.
[0004] However, the above-mentioned anti-leakage structure of the post-cast strip of the basement floor has shortcomings: since the right end face of the first segmented waterstop plate and the left end face of the second segmented waterstop plate need to be welded together at the lower side of the two segmented waterstop plates, and the lower space of the two segmented waterstop plates is severely limited, welding the end faces of the two segmented waterstop plates in such a severely limited space position undoubtedly increases the difficulty of welding; not only that, groundwater can easily leak from the end face welding points of the two segmented waterstop plates and enter above the segmented waterstop plates, failing to achieve a good anti-leakage effect. Utility Model Content

[0012] Among them, the first section waterstop steel plate and the second section waterstop steel plate have the same thickness, and the first end face of the first section waterstop steel plate and the first end face of the second section waterstop steel plate are connected together by arc welding. The welding point of the groove weld is a semi-cylindrical shape facing the water-facing surface below the basement floor.

[0016] Furthermore, in the anti-seepage structure of the post-cast strip of the basement floor, the second segmented water-stopping steel plate and the right side transverse water-stopping steel plate are welded on three sides.
[0017] Furthermore, in the anti-seepage structure of the post-cast strip of the basement floor, arc welding is used for each welding point between the first segmented water-stop steel plate and the left transverse water-stop steel plate, and each welding point between the second segmented water-stop steel plate and the right transverse water-stop steel plate.

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0025] This embodiment provides a basement floor post-casting anti-leakage structure. Figure 1 and Figure 2As shown, the anti-leakage structure of the post-cast strip of the basement floor of this embodiment includes a left transverse water-stop steel plate 1, a right transverse water-stop steel plate 2, and a plurality of transverse water-stop steel plate layers arranged in the transverse direction and at different longitudinal heights. The left transverse water-stop steel plate 1 is arranged in the horizontal direction of the basement floor, and the right transverse water-stop steel plate 2 is parallel to the left transverse water-stop steel plate 1 and arranged directly opposite to the left transverse water-stop steel plate 1; the left transverse water-stop steel plate 1 and the right transverse water-stop steel plate 2 are configured to be arranged on the water-facing surface of the basement; each transverse water-stop steel plate layer includes at least two transverse water-stop steel plates 3 arranged at intervals in the horizontal direction of the basement floor and parallel to each other. Among them:
[0026] For the transverse waterstop steel plates on the same floor, each transverse waterstop steel plate 3 includes a first segmented waterstop steel plate 31 and a second segmented waterstop steel plate 32. The first segmented waterstop steel plate 31 is arranged along the horizontal direction of the basement floor and is located between the left transverse waterstop steel plate 1 and the right transverse waterstop steel plate 2. The first segmented waterstop steel plate 31 has a first end face 31a and a second end face 31b welded to the left transverse waterstop steel plate 1; the second segmented waterstop steel plate 32 is arranged parallel to the first segmented waterstop steel plate 31 and is located between the left transverse waterstop steel plate 1 and the right transverse waterstop steel plate 2. The second segmented waterstop steel plate 32 has a first end face 32a and a second end face 32b welded to the right transverse waterstop steel plate 2. Among them, the first segmented water-stop steel plate 31 and the second segmented water-stop steel plate 32 have the same thickness, and the first end face 31a of the first segmented water-stop steel plate 31 and the first end face 32a of the second segmented water-stop steel plate 32 are welded by arc welding to connect the two first end faces together, and the welding point C of the groove welding is a semi-cylindrical shape facing the water-facing surface below the basement floor. Among them, the left transverse water-stop steel plate 1 and the right transverse water-stop steel plate 2 here have the same thickness, and the spacing distance between the two adjacent transverse water-stop steel plates 3 located in the same transverse water-stop steel plate layer is equal to the height of the post-casting strip, and the spacing distance here is the distance between the central axes of the two adjacent transverse water-stop steel plates.
[0027] For the transverse waterstop steel plates of the same layer, the first segmented waterstop steel plate 31 and the second segmented waterstop steel plate 32 have the same width, which is equal to the design specification width W of the above-mentioned right transverse waterstop steel plate 2. Of course, in actual application scenarios, the design specification width W of the right transverse waterstop steel plate 2 is not exactly the same.
[0028] Specifically in this embodiment:
[0029] The first segmented water-stop steel plate 31 and the left side transverse water-stop steel plate 1 are welded on three sides. Among them, the welding points between the first segmented water-stop steel plate 31 and the left side transverse water-stop steel plate 1 include the first welding point C11, the second welding point C12 and the third welding point C13. The first welding point C11 is located outside the left side transverse water-stop steel plate 1 and close to the upper end face of the first segmented water-stop steel plate 31. The second welding point C12 is located at the lower end face of the left side transverse water-stop steel plate 1 and close to the second end face 31b of the first segmented water-stop steel plate 31. The third welding point C13 is located between the lower end face of the left side transverse water-stop steel plate 1 and the upper end face of the first segmented water-stop steel plate 31.
[0030] The second segmented water-stop steel plate 32 and the right side transverse water-stop steel plate 2 are also welded on three sides. Among them, the welding points between the second segmented water-stop steel plate 32 and the right side transverse water-stop steel plate 2 include the first welding point C21, the second welding point C22 and the third welding point C23. The first welding point C21 is located on the outside of the right side transverse water-stop steel plate 2 and close to the upper end face of the second segmented water-stop steel plate 32. The second welding point C22 is located on the lower end face of the right side transverse water-stop steel plate 2 and close to the second end face 31b of the second segmented water-stop steel plate 32. The third welding point C23 is located between the lower end face of the right side transverse water-stop steel plate 2 and the upper end face of the second segmented water-stop steel plate 32.
[0031] Among them, arc welding is adopted for each welding point between the first segmented water-stopping steel plate 31 and the left transverse water-stopping steel plate 1 and each welding point between the second segmented water-stopping steel plate 32 and the right transverse water-stopping steel plate 2.
[0032] In order to better prevent groundwater in the concrete below the basement floor from leaking into the basement through the groove weld, in this embodiment, the groove weld C is a semi-cylindrical shape facing the water-facing surface below the basement floor. For example, the weld C here is a semi-cylindrical half-steel bar with a bottom diameter D of 16 mm. Of course, the thickness of the first segmented water-stopping steel plate 31 and the second segmented water-stopping steel plate 32 are both 6 mm.
[0033] It should be noted that for the welding of welding point C, a semi-cylindrical half-steel with a diameter of 16mm is used. The semi-cylindrical half-steel with a diameter of 16mm uses a special steel mill mold with a length of 3 meters, a semi-cylindrical concave base and an inner diameter slightly larger than 16mm. The steel furnace water is poured into the special steel mill mold, pressed into shape, and then forged into short steel bars with different widths and lengths.
[0034] The following combination Figure 1 and Figure 2 The anti-leakage principle of the anti-leakage structure of the post-cast belt of the basement floor in this embodiment is explained:
[0035] After the anti-leakage structure of the post-cast strip of the basement floor of this embodiment is poured with concrete, the groundwater in the concrete cannot leak from the non-welded part of the first segmented water-stop steel plate 31 and the second segmented water-stop steel plate 32 to the top of the entire transverse water-stop steel plate 3. At the same time, since the welding part of the first segmented water-stop steel plate 31 and the second segmented water-stop steel plate 32 adopts groove welding and the welding part is semi-cylindrical facing the water-facing surface below the basement floor, the concrete is in close contact with the welding part C of the semi-cylindrical groove welding, thereby achieving a water-stopping effect. At the same time, since the first segmented water-stop steel plate 31 and the left transverse water-stop steel plate 1 and the second segmented water-stop steel plate 32 and the right transverse water-stop steel plate 2 are all welded on three sides, this further enhances the anti-leakage effect of the anti-leakage structure of the post-cast strip of the entire basement floor. As for the anti-leakage structure of the post-cast strip of the entire basement floor, on the water-facing surface on the C side of the groove weld, the penetration length of the water-stop steel plate of the entire basement is less than the width of the water-stop steel plate, which has a good anti-leakage effect on the basement.
[0036] Although the preferred embodiments of the present invention are described in detail above, it should be clearly understood that the present invention may be modified and varied by those skilled in the art. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
