Description

Technical Field

[0001] The present application relates to a stepped drop plate connection structure and a manufacturing method, and belongs to the technical field of drainage structures in buildings. Background Art

[0002] With the vigorous development of prefabricated buildings in my country and the continuous improvement of people's living comfort, prefabricated toilets (including integral toilets and integrated toilets) have been widely used, and the corresponding toilet overall drop-down floor drainage design has become more and more common in architectural design. The overall drop-down floor of the bathroom provides conditions for the installation of the assembled integral toilet, but also brings difficulties to the design and construction. The range, height, and waterproof treatment of the intersection with the steel beam have always been difficult problems for designers to think about.

[0003] On the one hand, in prefabricated concrete structures, beams and slabs in water-filled rooms such as bathrooms are usually cast-in-place structures. Prefabricated integrated bathrooms usually have concrete beams around the bathroom, and the floor slab is lowered but the beam is not. The bathroom floor slab is directly lowered within a certain range, and the lowered slab boundary is on the inner side of the bathroom partition wall. The lowered slab range of the bathroom is guaranteed to be square and without bumps, and the structural beams around the lowered slab range are convex outwards, which does not affect the overall lowered slab range of the bathroom, so as not to affect the overall bathroom installation requirements.

[0004] On the other hand, in prefabricated concrete structures, the bathroom floor is directly dropped, e.g. Figure 1 As shown: the space within the drop plate range formed by the bathroom outer wall 1a, the main structural beam 2a, the secondary structural beam 3a and the structural bottom plate 4a is square. Although it can create good conditions for the installation of the overall bathroom, it also brings many disadvantages to other functional rooms: First, the structural beams around the bathroom drop-down slab (including the main structural beam 2a and the secondary structural beam 3a) are relatively large, and their width is greater than the partition wall width, and they are not flush with the partition wall. They will protrude outward from the wall and other functional rooms, forming room convex corners 21b and room convex edges 31a, resulting in convex beams in the bedroom, study, and living room, affecting the indoor use space and aesthetic effect. Second, the protruding room beams make it difficult to route the electrical pipelines in the room, and the side hanging design increases the project cost; Third, there are no structural components for rigid support around and at the corners of the bathroom waterproof chassis, but plastic rubber and other components are used for flexible support, resulting in problems such as unstable and shaking placement of the overall bathroom, affecting the integrity and stability of the assembled overall bathroom placement. Summary of the invention

[0005] In view of this, the present application first provides a stepped drop-plate connection structure, which is combined with the PEC beam to bear the force, so as to avoid the excessive cross-section of the component due to the force of a single beam, thereby enhancing the shelf stability and integrity of the assembled overall bathroom.

[0006] Specifically, the present application is implemented through the following scheme: A stepped drop-plate connection structure is suitable for integrated bathroom installation. A structural main beam and a structural secondary beam are respectively arranged below the outer wall of the bathroom. A PEC beam is arranged below the structural main beam. The main beam and the secondary beam are both provided with a stepped drop-plate connection structure on the side facing the inner side of the bathroom. The stepped drop-plate connection structure includes an integrally formed first step surface, a second step surface and a third step surface. The structural bottom plate is connected between the structural main beam and the structural secondary beam to form a first step surface; a second step surface is arranged between the first step surface and the outer wall, and the structural main beam directly above the PEC beam forms a third step surface.

[0007] Further, as a preference: The first step surface is provided with an adjustable support, the waterproof chassis is directly placed on the second step surface near the outer wall, and the remaining part is erected above the first step surface through the adjustable support.

[0008] A lower overhead space is formed between the first stepped surface and the waterproof chassis, a wall panel is installed at the end of the waterproof chassis, and a side overhead space is formed between the wall panel and the outer wall panel. The lower overhead space is used for drainage transverse pipes, and the side overhead space is used for water and electricity pipelines.

[0009] A waterproof layer is laid on the first step surface and the second step surface.

[0010] The main structural beam, the structural bottom plate and the structural secondary beam are an integrated structure. The main structural beam and the structural secondary beam protrude toward one side of the bathroom to form a second step surface, and the PEC beam is half-covered in the stepped lowering plate connection structure on the main structural beam.

[0011] The second step surface is flush with one side of the outer wall in the bathroom, and both sides of the third step surface are flush with both sides of the outer wall respectively.

[0012] The third step surface is higher than the level of the room floor panel.

[0013] The second object of the applicant is to provide a manufacturing method of the above-mentioned stepped drop-down board connection structure suitable for the overall bathroom shelf, the steps are as follows: Step 1: prefabricate PEC beams and install them on site; Step 2: On the inner side of the bathroom, a supporting stepped formwork is set up by attaching the PEC beam. Each step surface of the stepped drop plate is cast on site and vibrated to form the first step surface, the second step surface, and the third step surface, so that the stepped drop plate structure and the PEC beam form a whole and bear the force together; Step 3: In the middle of the bathroom, an adjustable support is set on the first step surface, the surroundings and corners of the waterproof chassis are placed on the second step surface, and the middle part is placed on the adjustable support.

[0014] The above scheme forms a stepped structure on the inner side of the integrated bathroom. The first step surface is the lowest, forming the waterproof chassis support of the integrated bathroom, and the second step surface constitutes a rigid support for the waterproof chassis near the wall corners and corners. Cooperating with the first step surface, it not only reduces the entire support of the waterproof chassis falling on the structural bottom plate, thereby reducing the thickness of the first step surface, increasing the indoor net height of the integrated bathroom, but also enhances the integrity and stability of the assembled integrated bathroom. The inner side of the third step surface located in the bathroom and the outer side located in the room are flush with the two side walls of the outer wall respectively, and the width of the stepped drop plate formed on the inner side is adjustable, and there is no protruding component on the side of the partition wall to avoid affecting other functional rooms. The above-mentioned stepped drop plate connection structure and the PEC beam combination are jointly stressed, which increases the bearing capacity of the stepped drop plate connection node and avoids the cross-section of the single beam load-bearing component being too large.

[0021] The present application provides a stepped drop plate connection structure suitable for overall bathroom placement. The following describes an embodiment of the present application in conjunction with the accompanying drawings.

[0022] Combination Figure 2 A main structural beam 2 and a secondary structural beam 3 are respectively arranged under the outer wall 1. The side close to the spray component A is the main structural beam 2, and the side close to the wash component B is the secondary structural beam 3.

[0023] Below the main structural beam 2 is the PEC beam 7. The main structural beam 2 and the secondary structural beam 3 are both provided with a stepped descending plate connection structure 6 on the inner side of the bathroom. The stepped descending plate connection structure 6 includes an integrally formed first step surface 61, a second step surface 62 and a third step surface 63. The structural bottom plate 4 is connected between the main structural beam 2 and the secondary structural beam 3, forming a first step surface 61. A second step surface 62 is provided between the first step surface 61 and the outer surrounding wall 1, so that the second step surface 62 is flush with a side wall of the outer surrounding wall 1 in the bathroom. The third step surface 63 is higher than the horizontal height of the room floor panel 11, and the two sides of the third step surface 63 are respectively flush with the inner and outer sides of the outer surrounding wall 1.

[0024] in: An adjustment support 81 is provided on the first step surface 61 , and the waterproof chassis 87 is directly placed on the second step surface 62 near the outer wall 1 , and the middle part is erected above the first step surface 61 through the adjustment support 81 .

[0025] A lower overhead space 51 is formed between the first step surface 61 and the waterproof chassis 8, a wall panel 12 is installed at the end of the waterproof chassis 8, and a side overhead space 52 is formed between the wall panel 12 and the outer wall panel 1. The lower overhead space 51 is used for drainage transverse pipes (such as Figure 3 , Figure 4 The drainage pipe 9 in the middle and the water and electricity pipelines in the side overhead space 52 are used.

[0026] A waterproof layer 64 may also be laid on the first step surface 61 and the second step surface 62 .

[0027] The above-mentioned structural main beam 2, structural bottom plate 4 and structural secondary beam 3 are an integrated structure. The structural main beam 2 and structural secondary beam 3 respectively protrude toward the inner side of the bathroom to form a second step surface 62, and the PEC beam 7 is half-covered in the stepped descending plate connection structure 6 on the structural main beam 2.

[0028] The junction between the stepped drop plate connection structure 6 and the PEC beam 7 is stepped. The stepped drop plate connection structure 6 and the PEC beam 7 are combined to bear force together, thereby increasing the bearing capacity of the connection node of the stepped drop plate connection structure 6 and avoiding excessive cross-section of the component due to the force on a single beam.

[0029] The stepped descending plate connection structure 6 protrudes from the inside of the bathroom, and the outside is flush with the outer wall 1 without any protruding components, which has no impact on the space of other functional rooms, and the stepped section width can be adjusted on the inside to prevent the stepped descending plate connection structure 6 from protruding from other rooms.

[0030] On the one hand, the second step surface 62 of the stepped drop-plate connection structure 6 serves as a rigid support device for placing the waterproof chassis 8 of the integrated bathroom, replacing the conventional plastic and rubber support parts around and at the corners of the waterproof chassis 8, thereby enhancing the integrity and stability of the assembled integrated bathroom.

[0031] On the other hand, the waterproof chassis 8 of the integrated bathroom is supported on the second step surface 62 on all sides and corners, which can greatly reduce the stress of all supports of the waterproof chassis 8 on the first step surface 61, thereby reducing the thickness of the first step surface 61 and increasing the net height of the bathroom.

[0032] The third step surface 63 of the stepped drop-slab connection structure 6 is higher than the floor slab 11 of the adjacent room, and can be used as a concrete rigid waterproof counter-slope and a base surface for the end of the waterproof membrane to enhance the waterproof effect.

[0033] The manufacturing steps of the above-mentioned stepped drop-down board connection structure suitable for the overall bathroom shelf are as follows: Step 1, prefabricate the PEC beam 7, and install the PEC beam 7 on site; Step 2: On the inner side of the bathroom, a supporting stepped formwork is set up by attaching the PEC beam 7. Each step surface of the stepped descending plate is cast on site and vibrated to form a first step surface 61, a second step surface 62, and a third step surface 63, so that the stepped descending plate connection structure 6 and the PEC beam 7 form a whole and bear force together; Step three, in the middle of the bathroom, an adjustment support 81 is set on the first step surface 61, the surroundings and corners of the waterproof chassis 8 are placed on the second step surface 62, and the middle part is placed on the adjustment support 82.

[0034] The above scheme forms a stepped structure on the inner side of the bathroom, with the first step surface 61 being the lowest, forming the middle support of the waterproof chassis 8 of the integrated bathroom, and the second step surface 62 being located near the corners and corners, forming a rigid support for the waterproof chassis 8. The first step surface 62 cooperates with the first step surface 61, not only to prevent the entire support of the waterproof chassis 8 from falling on the structural bottom plate 4, but also to reduce the thickness of the first step surface 61, thereby increasing the indoor net height of the integrated bathroom, and enhancing the shelving integrity and stability of the assembled integrated bathroom; the two sides of the third step surface 63 are respectively flush with the inner wall of the bathroom and the outer wall of the room located in the outer wall of the outer wall 1, and the width of the stepped drop plate connection structure formed on the inner side is adjustable, and there is no protruding component on the side of the partition wall to avoid affecting other functional rooms. The above-mentioned stepped drop plate structure and the PEC beam combination are jointly subjected to force, which increases the bearing capacity of the stepped drop plate connection node and avoids the cross-section of the single beam load-bearing component being too large.

[0035] The above-mentioned embodiments only express several feasible implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention, and the embodiments are not used to limit the scope of protection in the claims of the present invention. For ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, and all equivalent implementations or changes that do not depart from the present invention should be included in the technology of the present invention.
