Description

Technical Field

[0001] The present application relates to the field of building technology, and in particular to a super high-rise basement post-cast strip structure and a construction method. Background Art

[0002] Post-cast strips are concrete strips that are set at the corresponding positions of the foundation slab, wall, and beam in accordance with design or construction specifications to prevent harmful cracks that may occur in reinforced concrete structures due to uneven shrinkage or settlement. Modern high-rise buildings are all designed with underground garages. When the building exceeds the standard length and width, post-cast strips must be set on the basement floor in accordance with regulations to absorb the concrete structure constraint stress caused by concrete shrinkage deformation and settlement differences between the main and podium buildings, and avoid or reduce cracks in the concrete structure. Although the post-cast strip technology is not complicated, its beneficial effects are very obvious. It has been widely used in construction projects and has become one of the most effective technical measures for dealing with complex concrete plane structures and super-long concrete structures.

[0003] After the post-cast strip is made, in order to prevent debris and sewage from entering, it is necessary to take closed measures to allow it to stand for a period of time. According to the requirements, the standing and closing time should be no less than 45 days. After the post-cast strip has been standing for the prescribed time, the protective measures need to be removed for cleaning, the loose concrete on both sides of the post-cast strip needs to be chiseled out, the steel bars need to be rusted, and the garbage and silt need to be flushed into the cleaning pit and removed. If the cleaning is not in place, the joints will be loose, which will directly affect the quality of the project. Summary of the invention

If the cleaning is not in place, the joints will be loose, which will directly affect the quality of the project.

[0057] In order to solve the above problems, firstly, Figures 1 to 4 As shown, the present application provides a super-high-rise basement post-cast strip structure, comprising: an earthwork layer 1, a trench filling layer 2 and a pouring layer 3 stacked in sequence in a first direction extending vertically upward along the ground (such as the Z direction in the figure).

[0058] like Figure 2 , 3 As shown in Figures 5 and 6, a channel 11 is opened on the earthwork layer 1 along the second direction (such as the Y direction in the figure) extending from the post-cast zone, and a cleaning pit 12 is excavated in the channel 11; the channel 11 is filled with concrete to form a channel filling layer 2, and a cleaning extension pit 13 is also arranged on the channel filling layer 2, and the cleaning extension pit 13 is connected to the cleaning pit 12.

[0061] It can be understood that, for the convenience of construction, when making the sloped channel filling layer 2, the sloped earthwork layer 1 can be excavated first, and then the sloped earthwork layer 1 can be filled with concrete of equal thickness to form the sloped channel filling layer 2. The method for making the sloped earthwork layer 1 includes: excavating a first sub-channel 111 along the second direction in the earthwork layer 1, the depth of the first sub-channel 111 gradually increases, excavating a second sub-channel 112 in the opposite direction of the earthwork layer 1 along the second direction, so that the second sub-channel 112 is connected with the first sub-channel 111 to form the channel 11, and the depth of the first sub-channel 111 also gradually increases; excavating a cleaning pit 12 at the intersection of the first sub-channel 111 and the second sub-channel 112.

The first cast-in-place strip 41 and the second cast-in-place strip 42 are located on both sides of the channel filling layer 2.

[0063] It can be understood that the present application discloses a post-cast strip structure for a super-high-rise basement, which relates to the field of building technology, wherein the post-cast strip is located between the first cast-in-place strip 41 and the second cast-in-place strip 42, and the bottom of the post-cast strip is a channel filling layer 2, which is sloped and inclined to the cleaning pit 12. After the post-cast strip has been closed for a specified period of time, it is necessary to remove the protective measures for cleaning, chisel out the loose concrete and steel bars on both sides of the post-cast strip, and flush the silt and other garbage from the channel filling layer 2 into the cleaning pit 12 and clear it away. Therefore, the sloped channel filling layer 2 is conducive to the garbage swept into the post-cast strip to enter the cleaning pit along the slope of the surface, which is conducive to the rapid removal of the garbage, avoiding the problem of loose joints caused by inadequate cleaning, and ensuring the quality of the project.

[0064] like Figure 2 and Figure 3 As shown, in an optional embodiment of the present application, a first steel wire plate 51 and a second steel wire plate 52 perpendicular to the channel filling layer 2 are arranged between the upper steel mesh 31 and the lower steel mesh 32; the first steel wire plate 51 is arranged on the surface of the first cast-in-place strip 41 facing the second cast-in-place strip 42, and the second steel wire plate 52 is arranged on the surface of the second cast-in-place strip 42 facing the first cast-in-place strip 41; a first guide steel plate 61 is arranged on the first steel wire plate 51, and a second guide steel plate 62 is arranged on the second steel wire plate 52, and the first guide steel plate 61 and the second guide steel plate 62 are used to guide garbage into the channel filling layer 2.

[0065] It can be understood that the first cast-in-place strip 41 and the second cast-in-place strip 42 are both provided with guide steel plates for guiding the garbage into the channel filling layer 2, which is beneficial for guiding the garbage falling into the post-cast strip into the channel filling layer 2 during the static closing process of the post-cast strip, and then entering the cleaning pit 12 from the channel filling layer 2, making it easier to remove the garbage.

[0066] Continue to refer Figure 2 and Figure 3 In an optional embodiment of the present application, the first steel wire plate 51 includes a first upper steel wire plate 511 and a first lower steel wire plate 512, and the first guide steel plate 61 is fixed between the first upper steel wire plate 511 and the first lower steel wire plate 512; the second steel wire plate 52 includes a second upper steel wire plate 521 and a second lower steel wire plate 522, and the second guide steel plate 62 is fixed between the second upper steel wire plate 521 and the second lower steel wire plate 522.

[0067] Continue to refer Figure 2 and Figure 3 In an optional embodiment of the present application, a waterproof layer 4 and a waterproof layer protection layer 5 are stacked in sequence along the first direction between the earthwork layer 1 and the channel filling layer 2.

[0068] Second, as Figures 5 to 16 As shown, the present application provides a construction method for a super high-rise basement post-cast strip structure, comprising the following steps:

A second sub-channel 112 is excavated in the earthwork layer 1 along the opposite direction of the second direction, so that the second sub-channel 112 is connected with the first sub-channel 111 to form the channel 11, and the depth of the first sub-channel 111 also gradually increases.

[0070] like Figure 5 The diagram shows the earthwork layers. Figure 6 for Figure 5 A CC' cross-section diagram of Figure 7 for Figure 5 A DD' section diagram. Figure 7As shown, a first sub-ditch 111 is excavated in the earthwork layer 1 along the second direction (such as the Y direction in the figure), and the depth of the first sub-ditch 111 gradually increases, that is, the corresponding earthwork layer thickness gradually decreases, forming a slope earthwork; a second sub-ditch 112 is excavated in the earthwork layer 1 along the opposite direction of the second direction, so that the second sub-ditch 112 is connected with the first sub-ditch 111 to form the ditch 11, and the depth of the first sub-ditch 111 also gradually increases, that is, the corresponding earthwork layer thickness gradually decreases, forming another slope earthwork.

[0071] S2 . Dig a cleaning pit 12 at the intersection of the first sub-channel 111 and the second sub-channel 112 .

[0072] like Figure 7 As shown, the earthwork layer corresponding to the first sub-channel 111 is a slope earthwork inclined toward the cleaning pit, and the earthwork layer corresponding to the second sub-channel 112 is also a slope earthwork inclined toward the cleaning pit.

[0073] S3. Fill the area of ​​the channel 11 except the cleaning pit 12 with concrete to form a channel filling layer 2, so that a cleaning extension pit 13 connected to the cleaning pit 12 is formed on the filling layer.

[0074] like Fig.11 The CC' direction cross-section is shown after the earthwork layer forms the trench filling layer. Fig.12 This is the DD' direction profile after the earthwork layer forms the trench filling layer. Fig.12 It can be seen that the sloped earthwork layer 1 is filled with concrete of equal thickness to form a sloped trench filling layer 2.

[0077] S5. After the sealing is left to stand for a prescribed period of time, the casting layer 3 is cleaned and the garbage is flushed into the cleaning pit 12 and cleared away.

[0078] After the post-casting strip is made, in order to prevent debris and sewage from entering, it is necessary to take sealing measures and let it stand for a period of time. The sealing time is required to be no less than 45 days. Fig.15 As shown, during the static closing period of the post-cast strip, a closing plate 200 can be set at the top of the post-cast strip, that is, between the first cast-in-place strip 41 and the second cast-in-place strip 42, to prevent foreign debris from falling into the post-cast strip. After the post-cast strip has been static for a specified period of time, the protective measures need to be removed for cleaning, the loose concrete on both sides of the post-cast strip need to be chiseled out, the steel bars need to be rusted, and the garbage and sludge need to be flushed into the cleaning pit and cleared away.

[0079] S6. Fill concrete into the post-cast zone between the first cast-in-place zone 41 and the second cast-in-place zone 42.
