TECHNICAL FIELD

[0001] The utility model relates to the technical field of building structure's counterfort, specifically relates to a waterproof counterfort of secondary structure. BACKGROUND

[0002] In the current building field, when carrying out waterproof treatment to the kitchen and bathroom, the secondary counterfort structure is usually adopted, in the prior art, the secondary counterfort construction of secondary structure is mainly carried out by the secondary cast-in-situ method and the prefabrication method, the counterfort of cast-in-situ exists construction joint with the concrete structure floor, and water seepage problem is easily caused. The position of prefabricated counterfort needs to be fixed first, and then the pouring of beam plate is carried out, the counterfort root part is embedded into the concrete in the beam plate, this method needs sufficient depth, and the bottom of counterfort concrete block and the concrete base layer are not easy to appear leakage phenomenon. In the leakage place, with water accumulation exosmosis, indoor wall foot mildew, long hair, paint damage and other problems will be caused in the later period. Due to the functional difference of building structure, the floor slab of traditional residence is thick, can satisfy the construction condition of counterfort in the prior art, but for the apartment building, due to the thin floor slab, the existing counterfort structure construction will damage the protective layer of the floor slab, and may cause the floor seepage problem, even cause safety hazards. Therefore, in order to solve the waterproof counterfort construction problem of thin floor slab, solve the deficiency existing in the prior art waterproof counterfort structure, a new type of waterproof counterfort of secondary structure is urgently needed, which can satisfy the construction requirement of thin floor slab, and ensure the long-term waterproof and moisture-proof performance of the water area. CONTENT OF THE UTILITY MODEL

[0003] The utility model intends to provide a waterproof counterfort of secondary structure, which is mainly used for the waterproof counterfort construction of secondary structure of thin floor slab, and improves the waterproof and moisture-proof performance of the water area.

[0004] In order to achieve the above object, the utility model adopts the following technical scheme:

[0005] The utility model discloses a waterproof structure of floor slab and cast-in-situ counterfort arranged on the waterproof structure of floor slab, the waterproof structure of floor slab includes at least two waterproof lines and water cut groove located in the middle of the waterproof line, the waterproof line is composed of a plurality of continuous and staggered irregular grooves, the depth of the groove is 8mm-13mm, the size is 5mm-15mm, the depth of the water cut groove is 20mm-30mm, and the width is 30mm-40mm.

[0006] The principle and advantages of the scheme are:

[0007] Waterproofing and moisture-proofing are achieved by the floor waterproof structure and the cast-in-place reverse ridge arranged on the floor waterproof structure, and are specifically as follows. Waterproofing is achieved by the cast-in-place reverse ridge and the three additional lines of defense, of which two lines of defense are the waterproof lines on both sides, and the waterproof lines are composed of a plurality of continuous and staggered irregular grooves. The continuous and staggered grooves increase the path required for water seepage, and it is more difficult for water to seep out. In order to enhance the effect of anti-seepage, the groove depth is generally 8mm-13mm, and the size is 5mm-15mm. At the same time, the rough contact surface of the waterproof line can make the cast-in-place reverse ridge and the floor waterproof structure more closely combined, reduce or even eliminate the occurrence of construction joints, and further enhance the anti-seepage effect. The other line of defense is the water breaking groove. When the water in the water-involved room penetrates the waterproof line and breaks through the waterproof line to seep outwards, the seepage path is blocked by the water breaking groove. Considering the blocking effect and construction cost, the depth of the water breaking groove is set to 20mm-30mm, and the width is 30mm-40mm. Because the first and second lines of defense of the present scheme are very close, after the water seeps through the two lines of defense, there is very little water seepage. If the depth exceeds 30mm, it is a waste and will damage the floor. If the depth is less than 20mm, the effect is greatly reduced, and the accumulated water seepage will seep out of the water breaking groove. The width is also selected for the same reason. After comprehensive consideration, the size range described above is selected. The reasonable size can ensure the anti-seepage performance. Compared with the prior art, the present scheme has the advantages that the waterproof line can ensure the sealing waterproof effect without damaging the floor structure to cause floor cracks, the water breaking groove can block the water seepage path, and the four lines of defense are closely combined to improve the waterproof and moisture-proof performance of the water-involved area.

[0008] Preferably, as an improvement, a waterproof cement mortar layer is brushed on the area of the floor waterproof structure.

[0009] In order to enhance the waterproof performance, after the waterproof line and the water breaking groove are constructed, the area of the floor waterproof structure is cleaned to brush the waterproof cement mortar layer. When the waterproof line is constructed, cracks may occur in part of the floor area. The waterproof layer not only enhances the waterproof performance of the reverse ridge, but also blocks the water seepage path of the floor cracks.

[0010] Preferably, as an improvement, the cast-in-place reverse ridge is poured with anti-seepage concrete.

[0011] In order to further enhance the waterproof performance, the cast-in-place reverse ridge is poured with anti-seepage concrete. The cast-in-place secondary structure of the reverse ridge may have local cracks or honeycomb holes due to the incomplete vibration during pouring. Ordinary concrete may cause water seepage from the cast-in-place reverse ridge due to the above defects. In order to solve this defect, anti-seepage concrete is used. Because the capillary pores inside the anti-seepage concrete are different from those of ordinary concrete, water seepage cannot seep out of the anti-seepage concrete, thereby improving the anti-seepage effect.

[0012] Preferably, as an improvement, the cross section of the water breaking groove is triangular.

[0013] After considering the convenience of construction, the triangular section is selected after comparing with other shapes such as rectangle and trapezoid, which can reduce the difficulty of construction while ensuring the effect of the water break.

[0014] Preferably, as an improvement, the water break is provided with a waterproof protection strip with a flat top and a convex strip in the middle of the bottom, the width of the top of the waterproof protection strip is greater than the width of the water break, and the convex strip is clamped in the water break.

[0015] The anti-permeable concrete fills the water break during the casting of the cast-in-place reverse ridge, and in order to further enhance the anti-permeable and moisture-proof performance, the waterproof protection strip is arranged on the water break, which can effectively protect the water break during the casting of the anti-permeable concrete. The width of the top of the waterproof protection strip is greater than the width of the water break, which plays a role in covering and protecting the water break, and the convex strip at the bottom is clamped in the water break, which plays a role in limiting and preventing the waterproof protection strip from being dislocated and leaving the water break to affect the protection effect. The water break has a deeper groove under the protection of the waterproof protection strip during the casting of the reverse ridge, and after forming, the waterproof protection strip cooperates with the water break to form the core defense line in the middle, and the small amount of water that breaks through the waterproof line is blocked by the upper part of the waterproof protection strip, and the remaining small part penetrates into the water break. When the amount of water penetration is relatively large at some time, the deeper waterproof groove has stronger water resistance, and the upper and lower lines further improve the anti-permeable and moisture-proof performance.

[0016] Preferably, as an improvement, the lower surface of the top of the waterproof protection strip in contact with the waterproof structure of the floor is provided with a convex structure for guiding the water into the water break.

[0017] With the passage of time, due to the different materials of the waterproof protection strip and the concrete, a slight gap will appear at the joint between the two, and when the water penetration is too fast, the waterproof protection strip that completely fits the surface of the waterproof structure cannot guide the water into the water break in time, and after the water penetration accumulates for a long time, it will pass over the upper side of the waterproof protection strip, penetrate outward through the gap on the upper side, and cause damage to the wall of the external space. In order to prevent water from penetrating over the waterproof protection strip from the upper side, the lower surface of the top of the waterproof protection strip in contact with the waterproof structure of the floor is provided with a convex structure, which enhances the water drainage capacity and guides the water into the water break, thereby enhancing the anti-permeable effect. Moreover, the friction between the convex structure and the rough contact surface is larger, which can also prevent the waterproof protection strip from sliding.

[0018] Preferably, as an improvement, the water break is provided with a waterproof plate with a rectangular strip plate at the top and a support and a convex block at the bottom, the height of the rectangular strip plate is 150mm-200mm, the support at the bottom is supported on both sides of the water break, and the convex block is clamped in the water break.

[0019] Due to the different conditions and waterproof requirements of the water area, for the area with more water and the area with high waterproof requirement, such as the toilet, bathroom and the like. In order to further enhance the waterproof and moisture-proof performance, meet the anti-permeation requirement, the water blocking plate is vertically arranged in the water breaking groove, the lower part is provided with the protrusion for fixing the water blocking plate, the protrusion is clamped in the water breaking groove, so that the water blocking plate is fixed, and the water blocking plate is prevented from being displaced and tilted when pouring the anti-permeation concrete. After the cast-in-place reverse ridge is formed, the water blocking plate can further block the water seepage path, and the anti-permeation performance is improved. BRIEF DESCRIPTION OF DRAWINGS

[0028] The following is further described in detail through specific embodiments:

[0029] The reference signs in the drawings of the specification include: floor 1, cast-in-place reverse ridge 2, waterproof line 3, water breaking groove 4, waterproof protection strip 5, water blocking plate 6.

[0030] Example I Basically as shown in the drawings: Figures 1-4

[0031] The specific implementation process is as follows: the embodiment is suitable for the conventional water area, such as the drawings Figure 2 ​As shown, the floor waterproof structure includes at least two waterproof lines 3 and a water penetration groove 4 located between the waterproof lines 3. The waterproof line 3 is composed of a plurality of continuous and staggered irregular grooves, which increases the path required for water penetration, making it more difficult for water to penetrate out. In order to enhance the effect of anti-penetration, the depth of the groove is 8-13mm, and the size is 5-15mm. The rough contact surface of the waterproof line 3 can make the cast-in-place reverse ridge 2 and the floor waterproof structure more closely combined without damaging the floor 1 structure, reducing or even eliminating the occurrence of construction joints, and further enhancing the waterproof and anti-penetration effect. Figure 3 As shown, the cross section of the water penetration groove 4 is triangular. Considering the blocking effect and construction cost, the size of 30mm in depth and 40mm in width is selected. For general water area, the water quantity is small after being weakened by the two lines of cast-in-place reverse ridge 2 and waterproof line 3. The overall size of the water penetration groove 4 with a depth of 30mm and a width of 40mm is reasonable, which can effectively prolong the path required for water penetration without damaging the floor structure and ensure the anti-penetration performance.

[0032] Then, the anti-penetration concrete is poured and cured to form, as shown in Figure 4 As shown, the scheme adds three lines of waterproof lines 3 and water penetration grooves 4, and brushes waterproof cement mortar layer in the area of the floor waterproof structure, which cooperates with the cast-in-place reverse ridge 2 to form a waterproof reverse ridge with five lines of secondary structure. When water penetration occurs, the water penetration is blocked by the waterproof line 3 brushed with waterproof cement mortar layer. When the waterproof line 3 fails to block, the water penetration penetrates into the water penetration groove 4 brushed with waterproof cement mortar layer, which blocks the possibility of water penetration to the floor. The water penetration groove 4 blocks the path of water penetration to the outside, achieving good anti-penetration and moisture-proof effect.

[0033] As shown in Figures 5-6

[0034] The difference from example one is that, in order to further enhance the anti-penetration performance, a waterproof protection strip 5 is laid on the water penetration groove, as shown in Figure 5 As shown, the top of the waterproof protection strip 6 is rectangular, and the lower part is a triangular protrusion. The width of the top of the waterproof protection strip 5 is greater than the width of the water penetration groove 4. When installed, the lower protrusion is clamped in the water penetration groove 4, ensuring that the waterproof protection strip 5 is fixed in the water penetration groove 4, and the top rectangular strip completely covers the water penetration groove 4. When pouring the anti-penetration concrete, the waterproof protection strip 5 can protect the water penetration groove 4 and prevent the anti-penetration concrete from filling the water penetration groove 4, thereby enhancing the anti-penetration and moisture-proof performance of the water penetration groove 4. As shown in Figure 5 ​As shown, the lower surface of the top of the waterproof protection strip 5 in contact with the floor 1 is provided with a convex for guiding water seepage and preventing slipping, leaving a gap for guiding water seepage into the water cut-off groove 4. The water seepage is ensured to enter the gap from the gap, preventing the waterproof protection strip from sliding after being placed.

[0035] Then, the formwork is set up, the anti-seepage concrete is poured, and the forming is maintained, as shown in Figure 6 As shown, the waterproof structure of the floor 1 is obtained, which is composed of the waterproof line 3, the water cut-off groove 4, and the waterproof protection strip 5 fixed on the water cut-off groove 4, and the new secondary structure of the waterproof reverse ridge structure is obtained in combination with the upper cast-in-place reverse ridge 2. When water seepage occurs, the water seepage is blocked by the waterproof line 3 coated with the waterproof cement mortar layer, and when the blocking of the waterproof line 3 fails, the water seepage seeps into the water cut-off groove 4 from the gap between the waterproof protection strip 5 and the water cut-off groove 4, and the water cut-off groove 4 blocks the further seepage path of the water seepage, achieving the anti-seepage and moisture-proof performance.

[0036] As shown in Figures 7-8

[0037] The difference from the first embodiment is that after the waterproof cement mortar layer is coated, in order to further enhance the anti-seepage performance, the water blocking plate 6 is arranged in the water cut-off groove 4. The shape of the water blocking plate 6 is shown in the drawing. The height of the water blocking plate 6 is 150 mm-200 mm, and the bottom is provided with a convex block with a width and depth smaller than those of the water cut-off groove 4. The water blocking plate 6 is clamped into the water cut-off groove 4 through the convex block at the bottom of the water blocking plate 6, and the bottom two sides play a supporting role, while the water cut-off groove 4 is also protected, preventing the water blocking plate 6 from being washed away and the water cut-off groove 4 from being blocked during the pouring of the anti-seepage concrete. The lower seepage path is blocked by the water cut-off groove 4, and the upper seepage path is blocked by the water blocking plate 6, achieving further enhancement of the anti-seepage and moisture-proof performance. Then, the formwork is set up, the anti-seepage concrete is poured, and the forming is maintained, as shown in Figure 8 As shown, the waterproof structure of the floor 1 is obtained, which is composed of the waterproof line 3, the water cut-off groove 4, and the water blocking plate 6 fixed on the water cut-off groove 4, and the new secondary structure of the waterproof reverse ridge structure is obtained in combination with the upper cast-in-place reverse ridge 2. When water seepage occurs, the water seepage is blocked by the waterproof line 3 coated with the waterproof cement mortar layer, and when the blocking of the waterproof line 3 fails, the lower water seepage seeps into the water cut-off groove 4 coated with the waterproof cement mortar layer, and the upward seepage is blocked by the water blocking plate 6. The water cut-off groove 4 and the water blocking plate 6 block the further seepage path of the water seepage, further improving the anti-seepage and moisture-proof performance.

It should be pointed out that, for those skilled in the art, without departing from the technical solutions of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application.
