Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a tie-in component and a waterproof device for cantilever balconies. Background Technology

[0002] Cantilevered balcony designs allow balconies to extend beyond the main building, forming a bay window structure with three glass sides. This significantly increases indoor lighting area and view, enhancing living comfort. The cantilever design transfers loads to the main building through a beam-slab structure, simplifying foundation treatment.

[0003] Waterproofing and protective layers at the bottom of cantilevered balconies are typically installed after the main construction is completed. The waterproofing layer at the bottom of the balcony is usually designed as an SBS modified bitumen waterproof membrane, and the protective layer is usually concrete. The main problems with existing technologies are as follows: Because the waterproof layer at the bottom of the balcony is located at the bottom of the structure, it is prone to falling off due to the weight of the membrane. The cantilevered balcony has cantilever beams on three sides and a concave structure at the bottom, making it difficult to install the waterproof membrane at the bottom of the slab and making it impossible to guarantee the quality of construction. Since the bottom waterproof protective layer of the balcony is located at the bottom of the structure, the design requires backfilling with concrete before the construction of the bottom waterproof protective layer. However, since the bottom slab of the first-floor cantilevered balcony is usually poured at the same time as the basement exterior wall, the conditions for backfilling and waterproofing construction are not available before construction, so concrete construction cannot be carried out.

[0004] Therefore, there is an urgent need to design a tie-in component and a waterproofing device for cantilevered balconies to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a tie-in component and a waterproof device for cantilever balconies, which has the advantage that the waterproof protective layer is fixed to the main structure by embedded parts, making the waterproof protective layer at the bottom of the cantilever balcony slab and the waterproof protective layer at the bottom of the cantilever balcony beams easy to construct, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the specific technical solution of this utility model for a tie member and a waterproofing device for cantilevered balconies is as follows: A tie rod includes a main rod, which is L-shaped and can be inserted into a hole. A water-stop ring is connected to the main rod and fits against the upper surface of the hole to seal it. A fixing member is provided at one end of the main rod that passes through the hole. When the main rod is inserted into the hole and the water-stop ring fits against the upper surface of the hole, the fixing member fits against the lower surface of the hole to fix the main rod to the hole.

[0007] Furthermore, a threaded groove is provided at one end of the main rod that passes through the hole, and the fastener can be screwed into the threaded groove to fix the main rod to the hole.

[0008] Furthermore, the fasteners include a washer and a nut. The washer is fitted onto the end of the main rod that passes through the hole, and the nut can be screwed into the threaded groove to fix the washer, the main rod, and the hole.

[0009] A waterproofing device for a cantilevered balcony includes the aforementioned tie member, as well as a prefabricated component and a waterproof membrane. The prefabricated component is bonded to the waterproof membrane, and the end of the waterproof membrane away from the prefabricated component is connected to the cast-in-place balcony wall. The tie member passes through the prefabricated component and the waterproof membrane and fixes the prefabricated component and the waterproof membrane. The top of the tie member is fixed by the balcony wall.

[0010] Furthermore, the precast components include a first concrete slab and a second concrete slab, both of which are bonded to a waterproof membrane. The first concrete slab and the waterproof membrane are connected to the bottom of the balcony wall panel, and the second concrete slab and the waterproof membrane are connected to the bottom of the balcony wall beam.

[0011] Furthermore, the prefabricated components also include a first extruded polystyrene board, a second extruded polystyrene board, and a third extruded polystyrene board. The first, second, and third extruded polystyrene boards are all bonded to the waterproof membrane. The first extruded polystyrene board is connected to the end of the second concrete slab away from the first concrete slab. The first extruded polystyrene board and the waterproof membrane are connected to the outer side of the balcony wall beam. The two ends of the second extruded polystyrene board are connected to the first and second concrete slabs respectively. The second extruded polystyrene board and the waterproof membrane are connected to the inner side of the balcony wall beam. The third extruded polystyrene board is connected to the end of the first concrete slab away from the second concrete slab. The third extruded polystyrene board and the waterproof membrane are connected to the side of the balcony wall.

[0012] Furthermore, both the first and second concrete slabs have through holes, through which tie members pass to fix the first concrete slab and the waterproof membrane, as well as the second concrete slab and the waterproof membrane.

[0013] Furthermore, all waterproof membranes are provided with a first state and a second state; Before concrete is poured and the balcony wall is formed, the waterproof membrane is in its first state. The top surface and two sides of the first and second concrete slabs are bonded to the waterproof membrane, and the waterproof membrane that has been bonded to the two sides leaves a first distance to connect with the bottom surface of the first and second concrete slabs. When the concrete is poured and the balcony wall is formed, the waterproof membrane is in its second state. The waterproof membrane on the bottom surface of the first concrete slab is separated from the bottom surface of the first concrete slab, and the waterproof membrane that is not in contact with the balcony wall on the second concrete slab is separated from the second concrete slab. The separated waterproof membrane is then connected to the formed balcony wall, and the exposed balcony wall is overlapped with the new waterproof membrane through the separated waterproof membrane.

[0014] This utility model has the following advantages: This tie-in provides an initial seal to the opening via a water-stop ring and can be directly inserted into the opening and quickly installed via fasteners, simplifying joint treatment in waterproofing systems.

[0015] In this waterproofing system for cantilever balconies, the waterproof membrane is wrapped between the prefabricated components and the balcony walls, avoiding the risks of membrane delamination or detachment in traditional construction. This is especially beneficial for the bottom of cantilever balconies. Furthermore, the prefabricated components are used as formwork, reducing on-site formwork installation time. Since most of the waterproof membrane is prefabricated in the factory, only overlapping is required on-site, solving the problem of difficult membrane installation at the bottom of the balcony. The prefabricated components form an integral protective layer, covering all exposed areas (such as the inside and outside of beams and the sides of walls), ensuring the long-term effectiveness of the waterproofing system in harsh environments.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0019] The following is a reference to the appendix. Figure 1 To be continued Figure 3 This invention describes a tie-in component and a waterproofing device for a cantilevered balcony.

[0020] Because the waterproof layer at the bottom of the balcony is located at the bottom of the structure, it is prone to falling off due to the weight of the membrane. The cantilevered balcony has cantilever beams on three sides and a concave structure at the bottom, making it difficult to install the waterproof membrane at the bottom of the slab and making it impossible to guarantee the quality of construction.

[0021] Therefore, the tie rod 1 includes a main rod 11, which is L-shaped. A water-stop ring 12 is connected to the main rod 11. The water-stop ring 12 fits against the upper surface of the hole to seal the hole and form an initial sealing barrier to prevent water from seeping in. A fixing member 13 is provided on one end of the main rod 11 that passes through the hole. When the main rod 11 is inserted into the hole and the water-stop ring 12 fits against the upper surface of the hole, the fixing member 13 fits against the lower surface of the hole to fix the main rod 11 to the hole.

[0022] The main rod 11 has a threaded groove at one end that passes through the hole. The fastener 13 can be screwed into the threaded groove to fix the main rod 11 to the hole. Specifically, the main rod 11 includes a rod body connected to the lower end of the water-stop ring 12. The rod body located below the hole has a threaded groove, and the fastener 13 can be screwed into the threaded groove.

[0023] The fastener 13 includes a washer 131 and a nut 132. The washer 131 is sleeved on one end of the main rod 11 that passes through the hole. The nut 132 can be screwed into the threaded groove to fix the washer 131, the main rod 11 and the hole. The washer 131 distributes pressure evenly to prevent the nut 132 from loosening. The nut 132 fixes the tie member 1 to ensure that the water-stop ring 12 is firmly bonded to the waterproof membrane 3.

[0024] This tie-in 1 provides an initial seal via the water-stop ring 12 and can be directly inserted into the hole and quickly installed via the fastener, simplifying the handling of joints in the waterproofing system.

[0025] A waterproofing device for a cantilevered balcony includes the aforementioned tie member 1, as well as a prefabricated component 2 and a waterproof membrane 3. The prefabricated component 2 is bonded to the waterproof membrane 3. The end of the waterproof membrane 3 away from the prefabricated component 2 is connected to the cast-in-place balcony wall 6. The tie member 1 passes through the prefabricated component 2 and the waterproof membrane 3 and fixes the prefabricated component 2 and the waterproof membrane 3. The top of the tie member 1 is fixed during the casting of the balcony wall 6.

[0026] The precast component 2 includes a first concrete slab 21 and a second concrete slab 22. Both the first concrete slab 21 and the second concrete slab 22 are bonded to the waterproof membrane 3. The first concrete slab 21 and the waterproof membrane 3 are connected to the bottom of the balcony wall 6 slab, and the second concrete slab 22 and the waterproof membrane 3 are connected to the bottom of the balcony wall 6 beam. After installation, the first concrete slab 21 and the second concrete slab 22 serve as templates for concrete pouring to reduce on-site template installation time. At the same time, the first concrete slab 21 and the second concrete slab 22 serve as waterproof protective layers, covering the waterproof membrane 3 on them respectively to prevent the waterproof membrane 3 from falling off due to gravity. The waterproof membrane 3 is a waterproof material laid on the first concrete slab 21 and the second concrete slab 22 to prevent water from seeping in from the bottom of the slab or the bottom of the beam.

[0027] Specifically, both the first concrete slab 21 and the second concrete slab 22 are precast, and both the first concrete slab 21 and the second concrete slab 22 are reinforced with a single layer of bidirectional steel mesh inside to enhance the structural strength and durability.

[0028] The prefabricated component 2 also includes a first extruded polystyrene board 23, a second extruded polystyrene board 24, and a third extruded polystyrene board 25. The first extruded polystyrene board 23, the second extruded polystyrene board 24, and the third extruded polystyrene board 25 are all bonded to the waterproof membrane 3. The first extruded polystyrene board 23 is connected to the end of the second concrete slab 22 away from the first concrete slab 21. The first extruded polystyrene board 23 and the waterproof membrane 3 are connected to the outer side of the balcony wall 6 beam. The two ends of the second extruded polystyrene board 24 are connected to the first concrete slab 21 and the second concrete slab 22, respectively. The second extruded polystyrene board 24 and the waterproof membrane 3 are connected to the inner side of the balcony wall 6 beam. The third extruded polystyrene board 25 is connected to the end of the first concrete slab 21 away from the second concrete slab 22. The third extruded polystyrene board 25 and the waterproof membrane 3 are connected to the side of the balcony wall 6.

[0029] The first extruded polystyrene board 23, the second extruded polystyrene board 24, and the third extruded polystyrene board 25 are all extruded polystyrene boards, which are a type of waterproof protective material. The first extruded polystyrene board 23, the second extruded polystyrene board 24, and the third extruded polystyrene board 25, together with the first concrete slab 21 and the second concrete slab 22, form an integrated waterproof system, covering all exposed waterproof membrane 3 to prevent the waterproof membrane 3 from falling off.

[0030] Both the first concrete slab 21 and the second concrete slab 22 have through holes. The tie member 1 passes through the through holes to fix the first concrete slab 21 and the waterproof membrane 3, as well as the second concrete slab 22 and the waterproof membrane 3.

[0031] Waterproof membrane 3 is provided with a first state and a second state; Before the concrete is poured and the balcony wall 6 is formed, the waterproof membrane 3 is in the first state. The top surface and two sides of the first concrete slab 21 and the second concrete slab 22 are connected to the waterproof membrane 3, and the waterproof membrane 3, which is bonded to the two sides, leaves a first distance to connect with the bottom surface of the first concrete slab 21 and the second concrete slab 22. Specifically, the upper surface and sides of the first concrete slab 21 are hot-melt bonded to the waterproof membrane 3, and the waterproof membrane 3 with a first distance reserved is flipped onto the lower surface of the first concrete slab 21. The upper surface of the second concrete slab 22 is provided with a second distance. The second concrete slab 22 at the second distance is hot-melt bonded to the waterproof membrane 3. The unbonded waterproof membrane 3 covers the remaining positions on the upper surface and the sides of the second concrete slab 22. Then, the waterproof membrane 3 with the first distance reserved is flipped onto the lower surface of the second concrete slab 22.

[0032] Specifically, the first distance is any value greater than 20 cm and less than the length of the second concrete slab 22, so that the waterproof membrane 3 passing through the first distance can be easily overlapped with the new waterproof membrane 3 in the later stage. The second distance is the distance on the upper surface of the second concrete slab 22 minus the distance between the thicknesses of two second extruded polystyrene boards 24.

[0033] When the concrete is poured and the balcony wall 6 is formed, the waterproof membrane 3 is in the second state. The waterproof membrane 3 on the bottom surface of the first concrete slab 21 is separated from the bottom surface of the first concrete slab 21. The waterproof membrane 3 that is not in contact with the balcony wall 6 on the second concrete slab 22 is separated from the second concrete slab 22. The separated waterproof membrane 3 is connected to the formed balcony wall 6. The exposed balcony wall 6 is overlapped with the new waterproof membrane 3 through the separated waterproof membrane 3.

[0034] Specifically, the waterproof membrane 3 at the first distance on the first concrete slab 21 is separated from the first concrete slab 21, and the waterproof membrane 3 at the first distance on the first concrete slab 21 is connected to the formed balcony wall. The waterproof membrane 3 at the second distance on the second concrete slab 22 is separated from the second concrete slab 22, and the waterproof membrane 3 at the second distance on the second concrete slab 22 is connected to the formed balcony wall 6. The exposed balcony wall 6 is then connected to the new waterproof membrane 3 by the separated waterproof membrane 3, so that the waterproof membrane 3 are connected to form a whole.

[0035] In this waterproofing system for cantilevered balconies, the waterproof membrane 3 is wrapped between the prefabricated component 2 and the balcony wall 6, avoiding the risk of membrane delamination or detachment in traditional construction. This is especially beneficial for the bottom of cantilevered balconies. Furthermore, the prefabricated component 2 is used as a template, reducing on-site template installation time. Since most of the waterproof membrane 3 is prefabricated in the factory, only overlapping is required on-site, solving the problem of difficult membrane installation at the bottom of the balcony. The prefabricated component 2 forms an integral protective layer, covering all exposed areas (such as the inside and outside of beams and the sides of walls), ensuring the long-term effectiveness of the waterproofing system in harsh environments.

[0036] Construction steps for this cantilevered balcony: S1. Determine the design dimensions of prefabricated component 2 according to the design drawings and process and customize it accordingly; S2. Waterproof membrane 3 is applied to the upper surface and sides of the first concrete slab 21 and the second concrete slab 22, and the waterproof membrane 3 is flipped over to the lower surface of the first concrete slab 21 and the second concrete slab 22. S3. Positioning and laying out the lines to determine the positions of the wall 63, beam 61 and slab 62 of the cantilevered balcony; S4. Install two wall formwork templates 41 and reinforce them; S5, Construction and installation of beam and slab support system 5; Specifically, in S5, the beam and slab support system 5 includes a support pipe 51, a U-shaped bracket 52, and a main keel 53. First, the support pipe 51 is installed, which is the vertical support of the beam and slab support system 5. Then, the U-shaped bracket 52 is installed, and then the main keel 53 is installed on the U-shaped bracket 52. By adjusting the U-shaped bracket 52, the main keel 53 is adjusted to meet the design elevation.

[0037] S6. The second concrete slab 22, after the waterproof membrane 3 has been bonded, is installed on the beam-slab support system 5 and also serves as a formwork. Specifically, in S6, the second concrete slab 22, after the waterproof membrane 3 is bonded to the main keel 53, also serves as a formwork.

[0038] S7. Install two beam side formwork 42 on the waterproof membrane 3 of the second concrete slab 22; S8. The first concrete slab 21, after the waterproof membrane 3 is installed and bonded on the beam-slab support system 5, also serves as a template, and the two ends of the first concrete slab 21 are connected to the inner wall template 41 and the beam side template 42 respectively. Specifically, in S8, the first concrete slab 21, after the waterproof membrane 3 is installed and bonded on the main keel 53, also serves as a formwork.

[0039] S9. Drill holes in the first concrete slab 21 and the second concrete slab 22 after the waterproof membrane 3 has been bonded to form through holes. S10. Apply non-curing rubber asphalt waterproof coating to the through holes of the waterproof membrane 3, and then insert tie 1 into the through holes. The tie 1 is bonded to the through holes of the waterproof membrane 3 through the non-curing rubber asphalt waterproof coating to seal the through holes. Specifically, the main body rod 11 of the tie member 1 is inserted into the through hole, the water-stop ring 12 is attached to the upper surface of the through hole to seal the through hole, and the main body rod 11 is fixed to the through hole by the fastener 13 at one end of the main body rod 11 that passes through the through hole.

[0040] S11, Reinforcing steel bars for tied beams and floor slabs; S12. Pour concrete to form the balcony wall 6; S13. After the design strength of the balcony wall 6 reaches 100%, remove the wall formwork 41, the beam and slab support system 5, and the beam side formwork 42. S14. Separate the waterproof membrane 3 on the bottom surface of the first concrete slab 21 from the bottom surface of the first concrete slab 21, separate the waterproof membrane 3 on the second concrete slab 22 from the balcony wall that is not in contact with the second concrete slab 22, and connect the separated waterproof membrane 3 to the formed balcony wall 6. Overlap the separated waterproof membrane 3 with the new waterproof membrane 3 on the exposed balcony wall 6 to form a whole. S15. Adhere the first extruded polystyrene board 23, the second extruded polystyrene board 24 and the third extruded polystyrene board 25 to the exposed waterproof membrane 3 to protect the waterproof membrane 3.

[0041] This construction method for cantilever balconies allows for the simultaneous construction of the balcony wall 6, waterproof layer, and waterproof protective layer, significantly shortening the construction period. Compared to traditional segmented construction, it improves efficiency by approximately 30%. Furthermore, the combination of tie rod 1 and prefabricated component 2 solves the problem of the waterproof protective layer at the bottom of the balcony slab being impossible to construct, ensuring that the waterproof membrane 3 is free from hollow areas and falls off. The pre-reserved overlapping of the waterproof membrane 3 also reduces the need for on-site formwork and support system installation, thereby reducing construction difficulty and human error.
