Description

Technical Field

[0001] This utility model relates to the technical field of building construction, specifically to a reusable waterproof membrane temporary protective wall and temporary protective structure. Background Technology

[0002] In the foundation construction of a building project, the first step is to apply waterproof membrane to the bottom and side walls of the foundation. The waterproof membrane for the foundation side walls needs to be adhered to the sides of the pre-built brick formwork, with a 200-300mm overlap left at the top of the formwork to connect with the waterproof membrane for the later-applied basement exterior walls. Since the waterproof membrane at the top of the brick formwork and the waterproof membrane for the basement exterior walls cannot be applied continuously, protective measures must be taken for the reserved portion of the waterproof membrane at the top of the formwork to prevent damage and ensure the waterproofing effect of the subsequent membrane application.

[0003] Traditionally, the protection method for waterproof membrane on top of brick formwork involves constructing a 120mm high temporary protective wall using lime mortar. This temporary wall needs to be removed when the waterproof membrane on the basement exterior wall overlaps with the waterproof membrane on top of the brick formwork. Because lime mortar has low strength and cannot bond firmly to the waterproof membrane, the temporary protective wall is easily damaged and detached during construction due to impacts, losing its protective function for the waterproof membrane. This ultimately leads to damage to the waterproof membrane during the main structure construction, creating a potential for water leakage in the basement exterior walls later on. Utility Model Content

[0004] This utility model addresses the problem that the temporary protective wall on top of the brick formwork cannot be firmly bonded to the waterproof membrane, and that the membrane may fall off due to collisions during the construction of the main structure. It also protects the waterproof membrane reserved on top of the brick formwork from being damaged by the slope, thereby reducing the risk of water leakage in the basement exterior walls later. The utility model provides a reusable temporary protective wall and temporary protective structure made of waterproof membrane.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: This utility model provides a reusable waterproof membrane temporary protective wall, including a galvanized steel plate and an extruded polystyrene board. The galvanized steel plate includes a first bending section, a second bending section, a third bending section, and a fourth bending section connected sequentially and integrally. The first bending section is arranged vertically and is perpendicularly connected to the second bending section. The second bending section is arranged horizontally and is perpendicularly connected to the third bending section. The third bending section is perpendicularly connected to the fourth bending section. The first bending section and the third bending section are parallel to each other and the first bending section is located below the second bending section. On one side, the fourth bending segment is arranged parallel to the second bending segment and located on the side of the third bending segment away from the first bending segment. The end of the first bending segment away from the second bending segment is lower than the end of the fourth bending segment away from the second bending segment by a first preset distance. The extruded polystyrene board is adapted and fixed in the groove formed by the first bending segment, the second bending segment, and the third bending segment. The side of the extruded polystyrene board away from the second bending segment is the first abutting surface, and the side of the fourth bending segment away from the second bending segment is the second abutting surface. The first abutting surface is higher than the second abutting surface by a second preset distance.

[0006] The beneficial effects of this utility model are: This utility model provides a reusable waterproof membrane temporary protective wall, which can be reused and can replace the easily damaged masonry temporary protective wall on the top of the brick formwork. It protects the waterproof membrane reserved on the top of the brick formwork from damage, prevents water leakage from the basement exterior wall due to damage to the waterproof membrane, reduces the amount of work required for the initial construction and subsequent demolition of the temporary protective wall, and saves construction costs.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the first preset distance is not less than the height of the third bending segment.

[0009] The beneficial effect of adopting the above-mentioned further solution is that it can effectively cover and protect the waterproof membrane when it is flipped onto the brick mold.

[0010] Furthermore, the second preset distance is not less than the thickness of the waterproof membrane.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the waterproof membrane can be clamped under the extruded polystyrene board, effectively clamping and protecting the waterproof membrane.

[0012] Furthermore, the thickness of the extruded polystyrene board is 100~130mm.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by setting a reasonable thickness of extruded polystyrene board, the waterproof membrane can be effectively protected and scratched.

[0014] Furthermore, the thickness of the galvanized steel sheet is 4~6mm.

[0015] Furthermore, the first bent section has multiple connecting holes near its lower end.

[0016] The beneficial effect of adopting the above-mentioned further solution is that by setting multiple connection holes, the waterproof membrane can be fixed to the brick formwork when using it as a temporary protective wall.

[0017] Furthermore, the extruded polystyrene board is a solid structure or a hollow structure.

[0018] Furthermore, the hollow extruded polystyrene board is also provided with multiple vertically arranged support plates.

[0019] Furthermore, the cross-section of the extruded polystyrene board is rectangular.

[0020] This utility model also provides a temporary protective structure, including the aforementioned reusable waterproof membrane temporary protective wall, and further including a brick formwork, a waterproof membrane, and a basement exterior wall. One side of the basement exterior wall has a concrete foundation, and a brick formwork is built on one side of the concrete foundation. The height of the brick formwork is the same as the height of the concrete foundation. The waterproof membrane, installed in the ground below the basement exterior wall, extends upwards from between the brick formwork and the sidewall of the concrete foundation and wraps around to the outside from above the brick formwork. The temporary protective wall is fixed to the brick formwork, such that the first contact surface of the extruded polystyrene board abuts against the waterproof membrane above the brick formwork. The first bent section covers the waterproof membrane outside the brick formwork, and the second contact surface of the fourth bent section abuts against the upper surface of the concrete foundation.

[0021] The beneficial effects of this utility model are: the temporary protective structure of this utility model can effectively protect the waterproof membrane, prevent it from being exposed and damaged, and affect the subsequent connection with the waterproof membrane on the building exterior wall.

[0027] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0028] like Figure 1 and Figure 2 As shown, this embodiment provides a reusable waterproof membrane temporary protective wall, including a galvanized steel sheet 1 and an extruded polystyrene board 2. The galvanized steel sheet 1 includes a first bending section 11, a second bending section 12, a third bending section 13, and a fourth bending section 14 integrally connected in sequence. The first bending section 11 is vertically arranged and perpendicularly connected to the second bending section 12. The second bending section 12 is horizontally arranged and perpendicularly connected to the third bending section 13. The third bending section 13 is perpendicularly connected to the fourth bending section 14. The first bending section 11 and the third bending section 13 are parallel to each other and located below the second bending section 12. The fourth bending section 11... 4 is arranged parallel to the second bending section 12 and located on the side of the third bending section 13 away from the first bending section 11. The end of the first bending section 11 away from the second bending section 12 is lower than the end of the fourth bending section 14 away from the second bending section 12 by a first preset distance. The extruded polystyrene board 2 is adapted and fixed in the groove formed by the first bending section 11, the second bending section 12 and the third bending section 13. The side of the extruded polystyrene board 2 away from the second bending section 12 is the first abutting surface, and the side of the fourth bending section 14 away from the second bending section 12 is the second abutting surface. The first abutting surface is higher than the second abutting surface by a second preset distance.

[0029] like Figure 1 and Figure 2 As shown, in a preferred embodiment, the first preset distance is not less than the height of the third bending segment 13. This allows the waterproof membrane to be effectively shielded and protected when it is flipped onto the brick mold.

[0030] Preferably, the second preset distance is not less than the thickness of the waterproof membrane 3. The waterproof membrane can be clamped under the extruded polystyrene board to effectively hold and protect the waterproof membrane.

[0031] Optionally, the thickness of the extruded polystyrene board 2 in this embodiment is 100~130mm, such as 100mm, 105mm, 110mm, 115mm, 120mm, 125mm and 130mm. By setting a reasonable thickness of the extruded polystyrene board, the waterproof membrane can be effectively protected and scratched.

[0032] Optionally, the thickness of the galvanized steel sheet 1 in this embodiment is 4~6mm, for example 4mm, 4.5mm, 5mm, 5.5mm and 6mm.

[0033] like Figure 1 and Figure 2 As shown, the first bent section 11 in this embodiment has multiple connection holes near its lower end for expansion bolts 15 to pass through. By providing multiple connection holes, the waterproof membrane can be fixed to the brick formwork when used as a temporary protective wall.

[0034] The extruded polystyrene board 2 in this embodiment includes two optional structural forms: the extruded polystyrene board 2 is a solid structure or a hollow structure.

[0035] Furthermore, the hollow extruded polystyrene board 2 is also provided with multiple vertically arranged support plates.

[0036] Specifically, such as Figure 2 As shown, the cross-section of the extruded polystyrene board 2 in this embodiment is rectangular.

[0037] In this embodiment, the galvanized steel sheet 1 is a commonly available galvanized steel sheet. It can be processed according to the thickness of the brick formwork and the height of the temporary protective wall, and connection holes for installing expansion bolts 15 are pre-drilled in the bottom of the galvanized steel sheet. The extruded polystyrene board is a commonly available extruded polystyrene board with a compressive strength of not less than 0.3 MPa and a fire rating of not less than B1. It is bonded together with the 5mm thick galvanized steel sheet, which has been bent and formed, using adhesive. The expansion bolts 15 are common expansion bolts with a diameter of 6-8mm, mainly used to connect and fix the 5mm thick galvanized steel sheet to the outer side of the brick formwork wall.

[0038] This embodiment provides a reusable waterproof membrane temporary protective wall that can be reused to replace the easily damaged masonry temporary protective wall on top of the brick formwork. It protects the waterproof membrane reserved on top of the brick formwork from damage, preventing water leakage from the basement exterior wall due to damage to the waterproof membrane. It also reduces the amount of work involved in building and dismantling the temporary protective wall, saving construction costs.

[0039] Example 2

[0040] Based on Embodiment 1, this embodiment also provides a temporary protective structure, including a reusable waterproof membrane temporary protective wall as described in Embodiment 1, and further including a brick formwork 5, a waterproof membrane 3, and a basement exterior wall 6. The basement exterior wall 6 has a concrete foundation 4 on one side, and a brick formwork 5 is built on one side of the concrete foundation 4. The height of the brick formwork 5 is the same as the height of the concrete foundation 4. The waterproof membrane 3, installed in the ground below the basement exterior wall 6, extends upward from between the brick formwork 5 and the side wall of the concrete foundation 4 and wraps around to the outside from above the brick formwork 5. The temporary protective wall of the waterproof membrane 3 is fixed on the brick formwork 5, so that the first contact surface of the extruded polystyrene board 2 abuts against the waterproof membrane 3 above the brick formwork 5. The first bending section 11 covers the waterproof membrane 3 on the outside of the brick formwork 5, and the second contact surface of the fourth bending section 14 abuts against the upper surface of the concrete foundation 4.

[0041] Preferably, in this embodiment, the first bent section 11 is connected and fixed to the brick formwork 5 by means of expansion bolts 15 passing through the connecting holes. The brick formwork is mainly used for attaching the waterproof membrane to the foundation sidewall.

[0042] Specifically, such as Figure 2 As shown, the distance between the first and third bending sections is equal to the sum of the thickness of the brick formwork and twice the thickness of the waterproof membrane. That is, when the temporary protective wall of the waterproof membrane is placed on the brick formwork, the brick formwork and the waterproof membrane on both sides are sandwiched between the first and third bending sections.

[0043] In this embodiment, the height of the brick formwork is flush with the upper surface of the concrete foundation 4, allowing the waterproof membrane to overlap the brick formwork and be higher than the upper surface of the concrete foundation by one layer of waterproof membrane.

[0044] In this embodiment, the extension length of the fourth bending segment 14 on the concrete foundation 4 is less than the height of the third bending segment 13, and the fourth bending segment 14 can be fixed to the concrete foundation 4 with bolts.

[0045] In this embodiment, during the construction of the temporary protective structure, the bending shape and length of the 5mm thick galvanized steel plate 1 are determined according to the drawings and the wall thickness of the brick formwork on the outside of the foundation. Simultaneously, holes for installing expansion bolts 15 are pre-drilled at the bottom of the outer side of the 5mm thick galvanized steel plate. The shaped 5mm thick galvanized steel plate is then bonded and assembled with a 120mm thick extruded polystyrene board using adhesive. The assembled temporary protective wall is then fixed to the outer wall of the brick formwork using expansion bolts according to relevant construction requirements. When the waterproof membrane construction of the basement exterior wall begins in this construction section, the temporary protective wall is dismantled and moved to the next construction section.

[0046] The temporary protective structure in this embodiment can be used to replace the easily damaged temporary masonry protective wall on top of the brick formwork. It protects the waterproof membrane pre-installed on top of the brick formwork from damage, preventing water leakage from the basement exterior walls due to membrane breakage. This reduces the amount of work involved in constructing and dismantling the temporary protective wall, saving construction costs. The temporary protective structure effectively protects the waterproof membrane, preventing it from being exposed and damaged, which could affect its later connection with the waterproof membrane on the building's exterior walls.
