Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to an integrated concrete toilet caisson component and a mounting structure thereof. Background Art

[0002] In order to prevent water leakage from the internal water pipes of the bathroom and water seepage from the floor to the downstairs, a bathroom caisson is usually installed in the bathroom to allow the water leakage to flow into the bathroom caisson and then drain the water through the secondary drainage outlet of the bathroom caisson. In order to ensure the integrity between the bathroom caisson and the building, the bathroom caisson and the surrounding beams or columns are usually constructed by cast-in-place concrete. Although this construction method ensures the integration of the building structure and has high strength, on-site casting has the problems of large construction workload, long overall construction period, and difficult overall quality control. Utility Model Content

[0003] The utility model aims to provide an integrated concrete toilet caisson component to solve the problems of low construction efficiency, high construction cost and difficult to control construction quality of existing toilet caissons.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an integrated concrete toilet caisson component, comprising a caisson main body with a groove in the middle, the four sides of the top of the caisson main body all protrude outward to form a supporting side, and the caisson main body is provided with an upper steel mesh and a lower steel mesh arranged up and down, the upper steel mesh and the lower steel mesh are both bidirectional steel meshes with steel bars arranged in the longitudinal and transverse directions along the same plane, the ends of the upper steel mesh and the lower steel mesh extend outward to pass through the supporting side and are bent toward each other to form an upper anchor steel bar and a lower anchor steel bar respectively.

[0005] The principles and advantages of this solution are:

[0006] 1. The traditional on-site pouring method requires high labor, material and machinery costs, and the template reuse rate is low, the overall cost increases, and there are many on-site variables. The pouring quality depends on the workers' skills and is easily affected by climate, materials, etc., making it difficult to unify the molding quality; in this solution, the bathroom caisson is a prefabricated component produced in a standardized manner in the factory. The prefabricated components greatly reduce the on-site construction volume, labor and the impact on the surrounding environment, improve construction efficiency, and reduce construction costs. The factory prefabrication and standardized production effectively control the quality of the bathroom caisson, with good molding quality, making the overall performance of the bathroom caisson better.

[0007] 2. In this scheme, the four sides of the caisson body are provided with protruding supporting sides. During the specific installation, the supporting sides on all sides increase the contact area between the bathroom caisson and the prefabricated beams, making the prefabricated beams support the bathroom caisson more stable, reducing the workload of on-site support construction and adjustment, and improving construction efficiency; at the same time, each supporting side has upper and lower anchor steel bars protruding outward. The bending of the anchor steel bars increases its grip in the concrete, so that the connection nodes between the bathroom caisson and floor slabs, beams and other components have greater strength and rigidity, and the installation connection of the bathroom caisson is more stable.

[0008] 3. In this scheme, the bathroom caisson is connected to other components and concrete on all sides through supporting sides, which increases the rigidity of the overall connection structure. The frame structure formed by the four sides enables the bathroom caisson to disperse and transfer loads more effectively, improve the compression and shear resistance of the overall structure, and the protruding design on the four sides can better form constraints, reduce the possible displacement of the bathroom caisson under load, and ensure the stability of the overall building structure.

[0009] Furthermore, a connecting hole is opened on the bottom plate of the caisson body, and a water stop joint for connecting the upper and lower main drainage pipes is installed in the connecting hole.

[0010] The above-mentioned setting simplifies the traditional drainage riser installation processes such as formwork, on-site pouring, and formwork removal by pre-embedded water-stop joints on the bottom plate of the bathroom caisson, greatly improving the construction efficiency. The pre-embedded water-stop joints make it tightly connected to the bottom plate, avoiding water vapor from penetrating into the adjacent floor slabs through gaps, thereby improving the waterproof performance of the bathroom caisson.

[0011] Furthermore, drainage pipes and sanitary ware water supply pipes connected to each sanitary ware are buried in the caisson body.

[0012] The above arrangement simplifies the secondary opening and pipe laying after the bathroom box is formed, improves construction efficiency, and the pre-buried pipes reduce the space occupied by beams and columns, avoid structural changes, and are conducive to structural stability and high safety.

[0013] Furthermore, a wire tube is pre-buried in the bottom plate of the caisson body, a hand hole groove is opened at the bottom of the bottom plate, and the free end of the wire tube is located in the hand hole groove and is flush with the side surface of the bottom plate.

[0014] The pre-buried wire conduits solve the problem of the prior art that wire troughs need to be opened on the formed building body, and the hand hole groove design makes it unnecessary to precisely align the wire conduits when connecting the bathroom caisson to the prefabricated floor slabs of the adjacent rooms. The wire conduits can be adjusted in the hand hole grooves and then connected, which reduces the construction difficulty. It also reduces the position accuracy requirements of the wire conduits during prefabrication and improves production efficiency.

[0015] Furthermore, a hoisting groove is opened on the top of the caisson body, a hoisting member is installed in the hoisting groove and the top of the hoisting member is located in the hoisting groove.

[0016] Compared with the prior art in which the lifting parts protrude from the component surface, in the above arrangement, there is no need to cut off the lifting parts on the component surface after the bathroom caisson is lifted, thereby reducing the construction process. At the same time, when pouring concrete, the connection strength between the cast-in-place concrete layer and the caisson body is enhanced due to the lifting groove recessed in the concrete column and the top structure of the lifting parts in the form of a disc or a hemisphere.

[0017] Furthermore, a wiring hole is opened at the bottom of the base plate, a wiring box is installed in the wiring hole, and the wiring box is connected to the wire tube.

[0018] The above setting simplifies the installation steps of the lower-level electrical appliances. You only need to align the electrical appliances with the junction box for installation, which shortens the installation time. At the same time, the wire tube and junction box ensure that the wires are not directly exposed, effectively preventing moisture and water vapor from penetrating, reducing the risk of leakage and improving safety.

[0019] The utility model also provides a technical solution: an integrated concrete bathroom caisson installation structure, comprising a precast floor, a precast beam and a bathroom caisson, wherein the supporting side edges of the bathroom caisson and the ends of the precast floor are overlapped on the precast beams, and the precast floor, the precast beams and the bathroom caisson are enclosed to form a post-cast strip, the bottom reinforcement in the precast beam passes through the precast beam and is bent to form an outwardly extending longitudinal reinforcement, the outwardly extending longitudinal reinforcement and the upper anchor steel bars and the lower anchor steel bars are staggered and distributed and are all inserted into the post-cast strip, and the post-cast strip is filled with concrete.

[0020] Beneficial effects:

[0021] 1. In this scheme, the bathroom caisson, prefabricated floor slab and prefabricated beam are all prefabricated components. Prefabricated components effectively solve the problems of long construction period, heavy labor and inconsistent construction quality when using traditional casting methods to construct bathroom caissons and beams, and meet the standardization and modernization requirements of prefabricated buildings.

[0022] 2. During the specific installation of this scheme, the bathroom caisson and prefabricated floor slab are placed on the prefabricated beams through hoisting. The bathroom caisson is provided with supporting sides on all sides, and each supporting side has upper and lower anchoring steel bars protruding outward. The upper and lower anchoring steel bars are staggered with the outward longitudinal bars on the prefabricated floor slab and are connected and fixed with concrete in the post-cast strip, which enhances the stiffness, strength and shear resistance of the concrete in the post-cast strip after forming, making the connection between the bathroom caisson and the surrounding prefabricated floor slabs and prefabricated beams more stable.

[0023] Furthermore, an installation gap is left between the outer wall of the caisson body and the side wall of the prefabricated beam.

[0024] The installation gap in the above setting facilitates the precise alignment of the bathroom caisson during installation. At the same time, the installation gap provides adjustment space for subsequent position adjustment, and the installation gap can absorb the slight deformation of the component during use, avoiding direct extrusion causing structural damage or cracks.

[0025] Furthermore, the prefabricated beam is detachably connected to a side of the prefabricated floor slab with an adjustable support device, the adjustable support device includes a fixed plate and a support unit, the fixed plate is provided with two shaped holes and is welded with a connecting piece, the connecting piece is vertically provided with an installation hole, the support unit includes a support plate and a support rod welded to the bottom of the support plate, the support rod is threaded with an adjusting nut, and the support rod is inserted into the installation hole.

[0026] The above arrangement eliminates the need for building a full-length scaffolding for support during the installation of the prefabricated floor slabs as in the prior art, thereby reducing the construction process of scaffolding erection and disassembly, greatly improving construction efficiency; and when the horizontal height of the prefabricated floor slab needs to be adjusted, the adjusting nut can be screwed with a wrench to meet the on-site support height adjustment requirements, and the construction flexibility is higher.

[0027] Furthermore, a bolt sleeve for fixing the adjustable supporting device is pre-embedded on one side of the prefabricated beam close to the prefabricated floor slab.

[0028] The adjustable support device can be detachably fixed to the prefabricated beam by means of bolts and bolt sleeves. The operation is simple and quick, which greatly improves the construction efficiency. The bolt connection makes it easy to disassemble and reuse the adjustable support device after the prefabricated floor is installed, thereby reducing construction costs.

[0036] The following is further described in detail through specific implementation methods:

[0037] The figure marks in the drawings of the specification include: bathroom caisson 1, caisson body 11, bottom plate 12, hand hole groove 121, junction box 122, connection hole 123, support side 13, upper anchor steel bar 14, lower anchor steel bar 15, prefabricated floor 2, extending longitudinal reinforcement 21, prefabricated beam 3, post-cast strip 4, lifting groove 5, lifting part 6, adjustable support device 7, fixing plate 71, connecting part 72, support plate 73, support rod 74, adjusting nut 75.

[0038] Example

[0039] like Figure 1-Figure 4 As shown, an integrated concrete bathroom caisson component includes a caisson body 11 with a rectangular groove in the middle, the top of the caisson body 11 protrudes outward on all sides to form a supporting side 13, the caisson body 11 and the supporting side 13 are formed as one piece, and the caisson body 11 is provided with an upper steel mesh and a lower steel mesh arranged up and down, the upper steel mesh and the lower steel mesh are both bidirectional steel meshes with steel bars arranged in both the longitudinal and transverse directions along the same plane, the bidirectional steel bar arrangement enhances the overall rigidity and strength of the bathroom caisson 1, and there is no need to lay and pour steel bars on site. The ends of the upper and lower steel meshes extend outwardly through the supporting side edges 13 and are bent downwardly and upwardly respectively to form upper anchoring steel bars 14 and lower anchoring steel bars 15. The outward extension length of the lower anchoring steel bars 15 is greater than that of the upper anchoring steel bars 14. The upper anchoring steel bars 14 are located within the bending area of ​​the lower anchoring steel bars 15, thereby achieving misalignment of the upper and lower anchoring steel bars 14, 15, and avoiding a situation in which a large distribution area of ​​steel bars is distributed and steel bars collide with other components during installation due to misalignment in the horizontal direction, thereby reducing the amount of on-site steel bar adjustment and improving construction efficiency.

[0040] Drain pipes and water supply pipes for sanitary ware connected to toilets, bathtubs, absorption tanks, etc. are pre-buried in the caisson body 11. The water supply pipes for sanitary ware and the drainage pipes supply water and discharge sewage to each sanitary ware respectively. One end of the drainage pipe is connected to the main drainage pipe. The buried positions of the drainage pipe and the water supply pipe for sanitary ware are arranged according to the actual needs of the user. A connecting hole 123 is opened on the bottom plate 12 of the caisson body 11. A water stop joint connecting the main drainage pipes of the upper and lower floors is installed in the connecting hole 123. By setting up the pre-buried pipeline, the process of laying the secondary pipeline is reduced, the construction efficiency is improved, and the damage to the formed building body is avoided. At the same time, the pre-buried pipeline can be partially opened when the pipeline is repaired, which does not affect the overall use, is convenient for maintenance, and reduces costs.

[0041] like Figure 3As shown, a wire tube is embedded in the bottom plate 12 of the caisson body 11, and a hand hole groove 121 with a notch facing downward is opened at the bottom of the bottom plate 12. The free end of the wire tube is located in the hand hole groove 121 and is flush with the side surface of the bottom plate 12; a wiring hole is also opened at the bottom of the bottom plate 12, and a wiring box 122 is installed in the wiring hole, and the wiring box 122 is connected to the wire tube. Through the above arrangement, the process of grooving and wiring on the building body in the later stage is simplified, and the overall assembly efficiency is higher. When the bottom plate 12 is connected to the adjacent floor slab for the wire tube, the line segment angle can be adjusted through the activity space of the hand hole groove 121, which increases the assembly flexibility and effectively reduces the difficulty of accurate connection of the wire tube.

[0042] like Figure 2 , Figure 4 As shown in the figure, the top of the caisson body 11 is provided with a hoisting groove 5, which is preferably hemispherical. A hoisting member 6 is buried on the caisson body 11, and the hoisting member 6 is generally large at both ends and small in the middle. Specifically, the top of the hoisting member 6 is a disc or a hemispherical body, and the bottom of the hoisting member 6 (the part buried in the caisson body 11) is a disc, or it can be formed by a plurality of steel bars distributed equidistantly. The top of the hoisting member 6 is located in the hoisting groove 5 and does not exceed the upper surface of the caisson body 11. Through the above structure, compared with the hoisting member 6 protruding from the surface of the component in the prior art, this solution does not need to cut off the hoisting member 6 protruding from the surface of the component after the hoisting is completed, thus reducing the construction process. At the same time, when pouring concrete, due to the hoisting groove 5 concave in the supporting side 13 and the top structure of the hoisting member 6 in the form of a disc or a hemispherical body, the connection strength between the cast-in-place concrete layer and the caisson body 11 is enhanced.

[0043] like Figure 5 As shown, this embodiment also provides an integrated concrete toilet caisson installation structure: including a toilet caisson 1, a precast floor 2 and a precast beam 3, the supporting side 13 of the toilet caisson 1 and the end of the precast floor 2 are overlapped on the precast beam 3, the precast floor 2, the precast beam 3 and the toilet caisson 1 are enclosed to form a post-cast strip 4, the bottom reinforcement in the precast beam 3 passes through the precast beam 3 and bends upward to form an extended longitudinal reinforcement 21, the extended longitudinal reinforcement 21 and the upper anchor steel bar 14 and the lower anchor steel bar 15 are staggered and inserted into the post-cast strip 4, the post-cast strip 4 is filled with concrete, and after the concrete solidifies, the toilet caisson 1, the precast floor 2 and the precast beam 3 are connected and fixed. During installation, an installation gap is left between the outer wall of the caisson body 11 and the side wall of the precast beam 3. In this embodiment, the installation gap is preferably 20 mm, so as to adapt to the slight deformation of the components during use and avoid direct extrusion or cracks between the components.

[0044] like Figure 6 , Figure 7As shown in the figure, a bolt sleeve (not shown in the figure) is pre-buried on one side of the prefabricated beam 3 close to the prefabricated floor slab 2, and an adjustable supporting device 7 is fixed to the prefabricated beam 3 through the bolt sleeve bolts. The adjustable supporting device includes a fixing plate 71 and a supporting unit. The fixing plate 71 is provided with two strip holes corresponding to the bolt sleeves and is welded with a connecting piece 72. The connecting piece 72 is vertically provided with a mounting hole. The supporting unit includes a supporting plate 73 and a supporting rod 74 welded to the bottom of the supporting plate 73. An adjusting nut 75 is threadedly connected to the supporting rod 74, and the supporting rod 74 is inserted into the mounting hole. When the prefabricated floor 2 is installed, bolts are passed through the strip holes to fix the adjustable supporting device 7 on the prefabricated beam 3, and then the prefabricated floor 2 is placed on the adjustable supporting device 7 for support. When the horizontal height of the floor needs to be adjusted, the adjusting nut 75 can be screwed with a wrench. In this way, there is no need to set up a scaffolding to support the floor, thereby reducing the construction process of scaffolding erection and disassembly, greatly improving the construction efficiency. At the same time, after the construction of the prefabricated floor 2 is completed, the adjustable supporting device 7 can be removed from the bolt sleeve and reused.
