Description

Technical Field

[0001] The utility model belongs to the technical field of building engineering, and in particular relates to a hanging mold device for lowering a floor of a toilet structure. Background Art

[0002] In order to meet the indoor waterproofing function, the bathroom floor steel structure surface elevation is usually designed to be lower than other rooms in the room, forming an indoor floor height difference. The traditional floor lowering construction method usually uses wooden squares, angle steels or square tubes as side forms, and fixes the side forms on the floor steel bars or steel stirrups. When fixed on the steel bars, quality problems such as large deviation of the protective layer and large deviation of the structural size will occur; when fixed on the steel stirrups, the construction process is cumbersome, the cross-influence is large, and the amount of measure bars is large. In addition, when pouring structural concrete, the floor height difference is often due to the problem of hanging formwork support. On the one hand, the hanging formwork may be moved due to the impact of concrete during the pouring project due to the instability of the hanging formwork support, which affects the quality of concrete pouring. On the other hand, the construction speed of conventional hanging formwork support is slow and the construction efficiency is low. On the third hand, due to improper setting of the hanging formwork support points, there may be more penetration points at the bathroom floor steel bars, thereby affecting the self-waterproofing effect of the bathroom floor steel structure. Utility Model Content

[0003] Therefore, the utility model provides a hanging formwork device for lowering the floor of the bathroom structure, which can overcome the problems in the prior art that the hanging formwork is not firm, the construction speed and efficiency of conventional hanging formwork are slow, and the improper setting of the hanging formwork support points leads to poor self-waterproofing effect of the bathroom floor steel structure.

[0004] In order to solve the above problems, the utility model provides a hanging formwork device for lowering the structure of a bathroom, including a hanging board frame formed by a plurality of hanging boards, the outer wall of the hanging board frame abuts against the structural beam on the surrounding side of the bathroom, a plurality of first frame beams are arranged at intervals along the width direction of the hanging board frame, the first frame beams extend along the length direction of the hanging board frame, and the first frame beams close to the hanging boards are also fixedly connected to a plurality of second frame beams, the second frame beams are vertically arranged with the first frame beams, the free ends of the second frame beams extend toward the hanging boards and are fixedly connected to the hanging boards, both ends of the first frame beam and the free ends of the second frame beams extend out of the hanging boards to form protruding ends, the bottom of the protruding ends are provided with pads, the pads abut against the structural beams, and are used to maintain a preset distance between the hanger boards and the floor slab reinforcement, the first frame beams and the second frame beams are used to carry heavy objects.

[0005] In some embodiments,

[0006] The extension length of the protruding end is greater than or equal to the width of the structural beam.

[0007] In some embodiments,

[0008] When the width of the bathroom is less than or equal to 3m, two or three first beams are arranged at equal intervals.

[0009] In some embodiments,

[0011] In some embodiments,

[0012] When the width of the bathroom is greater than 4m, the number of the first beams is greater than or equal to 4.

[0013] In some embodiments,

[0023] The utility model provides a hanging formwork device for lowering the floor of a bathroom structure. After the hanging plate, angle brace, first frame beam, second frame beam, pad, hook and other components are assembled and installed, the on-site hoisting operation is carried out. After the floor slab reinforcement and beam body reinforcement are tied, before the concrete is poured, the hanging formwork device is directly hoisted or manually transported to the designed position by a tower crane, and the heavy objects are evenly placed on the beam frame of the device. After the concrete is poured, the heavy objects are unloaded and the hooks are hung for quick disassembly. The hanging plate frame in the device has a fixed size and high rigidity. At the same time, the relative positions between the outer side of the hanging plate and the beam body reinforcement form a mutual clamping effect, which can effectively avoid deformation and movement of the frame during the pouring process and ensure the casting quality of the concrete components.

[0033] See also Figures 1 to 7 As shown, according to an embodiment of the utility model, a hanging formwork device for lowering the floor of a bathroom structure is provided, comprising a hanging board frame formed by a plurality of hanging boards 1, the outer wall of the hanging board frame abuts against the structural beam 2 on the side of the bathroom, a plurality of first frame beams 3 are arranged at intervals along the width direction of the hanging board frame, the first frame beams 3 extend along the length direction of the hanging board frame, the first frame beams 3 close to the hanging board 1 are also fixedly connected with a plurality of second frame beams 6, the second frame beams 6 are vertically arranged with the first frame beams 3, the free ends of the second frame beams 6 extend toward the hanging board 1 and are fixedly connected with the hanging board 1, both ends of the first frame beam 3 and the free ends of the second frame beams 6 extend out of the hanging board 1 to form an extended end, the bottom of the extended end has a cushion block 7, the cushion block 7 abuts against the structural beam 2, and is used to keep a preset distance between the hanging board 1 and the floor reinforcement, the first frame beams 3 and the second frame beams 6 are used to bear heavy objects. The integrated hanging board frame structure is simple in structure and quick and easy to install. The first frame beam 3 and the second frame beam 6 carry heavy objects to keep the position of the hanging plate frame from moving. The relative positions between the outer side of the hanging plate 1 and the beam body steel bars form a mutually clamping effect, which can effectively avoid the deformation and movement of the hanging plate frame during the pouring process and ensure the pouring quality of the concrete components. In addition, the upper steel bars of the beam body of the surrounding structural beams are used as support points, replacing the method of using the floor steel bars as the conventional hanging formwork support points, which can effectively avoid the influence of the supporting embedded objects on the structural self-waterproof floor steel bars and meet the waterproof use function. The pad 7 is set to keep a preset distance between the hanging plate 1 and the floor steel bars to prevent the concrete pouring at the corner of the bathroom wall from being affected during the pouring process.

[0034] In a specific embodiment, the height of the hanging plate 1 is consistent with the height of the lowering plate (for example, 100 mm). The hanging plate 1 is welded into a hanging plate frame using square steel with a size of 100×50×2 mm. The outer size of the frame should be consistent with the size of the bathroom structure. Figure 4 shown.

[0035] In a specific embodiment, a pad is welded at the bottom of the cantilever end (i.e., the extended end) of the second frame beam 6. The pad thickness is consistent with the thickness of the upper steel bar protection layer of the bathroom floor steel bar. The pad is made of a 25mm thick iron plate with a processing size of 150×100mm. Other materials that are easy to weld and have a certain load-bearing capacity can also be used for replacement.

[0036] In a specific embodiment, the first frame beam 3 and the second frame beam 6 are placed on the beam body of the structural beams around the bathroom floor reinforcement. All loads of the hanging formwork device are transferred from the frame beams to the beam body reinforcement. They are made of 75×75×5.0mm angle irons and welded to the hanging plate frame.

[0037] In some embodiments, the extension length of the protruding end is greater than or equal to the width of the structural beam 2. Designing the extension length of the protruding end to be greater than or equal to the width of the structural beam 2 can improve the support stability of the second frame beam 6 and ensure that the second frame beam 6 will not move during the concrete pouring process. Preferably, the extension length of the protruding end is equal to the width of the structural beam 2.

[0038] In some embodiments, when the width of the toilet is less than or equal to 3m, two or three first beams 3 are arranged at equal intervals. When the width of the toilet is less than or equal to 3m, arranging the first beams 3 at equal intervals can make the gravity distribution of the heavy objects more uniform, ensure that the hanging board frame is evenly stressed, improve the stability of the hanging board structure, and thus improve the quality of concrete pouring. Preferably, two first beams 3 are arranged at equal intervals.

[0039] In some embodiments, when the width of the bathroom is greater than 3m and less than or equal to 4m, the distance between the hanger board 1 and the first frame beam 3 arranged along the length direction of the hanger board frame is 1m. When the width of the bathroom is greater than 3m and less than or equal to 4m, more first frame beams 3 need to be arranged due to the large span of the bathroom. Although this arrangement ensures the bearing capacity of the frame beams and the force of the hanger board frame, it increases the construction cost. Setting the position of the first frame beam 3 and the distance between the first frame beam 3 to 1m can effectively solve this problem. It can not only ensure the stability of the hanger board frame under the load of heavy objects, but also reduce the construction cost. Preferably, two first frame beams 3 are designed, and the distance between the two frame beams and the nearest hanger board 1 is 1m.

[0040] In some embodiments, when the width of the toilet is greater than 4m, the number of the first beams 3 is greater than or equal to 4. When the width of the toilet is greater than 4m, more heavy objects need to be carried to ensure the stability of the hanging board frame, so more first beams 3 need to be set, and the number should be greater than or equal to 4 according to the load-bearing capacity. Of course, as the strength of the material structure continues to increase, the number of beams will decrease accordingly.

[0041] In some embodiments, two adjacent hanging boards 1 are provided with angle braces 5 at a preset angle between the two hanging boards 1. The provision of the angle braces 5 increases the support strength between the two hanging boards 1 at a preset angle, especially at the corners of the bathroom, the addition of the angle braces 5 can stabilize the support capacity of the corners of the hanging board frame, strengthen the rigidity of the hanging board frame, resist the deformation caused by the impact force during the concrete pouring process, and make the entire structure more stable.

[0042] In a specific embodiment, 50×50×3.0 mm angle irons are welded at the four corners of the hanging plate frame as angle braces 5. The welding positions on both sides of the angle braces 5 are 500 mm away from the corners of the hanging plate frame. The angle braces 5 are arranged at this position to achieve a better support effect and save construction costs. Figure 5 shown.

[0043] In some embodiments, the top of the four corners of the hanging plate frame is provided with a hook 4. The hooks 4 are welded at the four corners of the hanging plate for the overall hanging of the mold hanging equipment, which is convenient and fast, and realizes the rapid disassembly and assembly of the hanging mold device.

[0044] In some embodiments, the second beams 6 are arranged at equal intervals along the length direction of the hanging plate frame. The second beams 6 arranged at equal intervals make the load-bearing capacity more uniform and improve the overall stability of the hanging plate frame.

[0045] In some embodiments, the hanging plate 1, the first frame beam 3, the second frame beam 6 and the angle brace 5 are all steel structures. The steel structure has a stronger bearing capacity, and other materials that can play a supporting role are also acceptable.

[0046] In a specific embodiment, the hanging plate 1 is square steel, and the first frame beam 3, the second frame beam 6 and the angle brace 5 are angle irons. According to different structural bearing capacities, the structural shape is reasonably selected to reduce the construction cost.

[0047] In some embodiments, the outer peripheral wall of the hanging plate frame has several groups of chutes, and a slide plate is slidably arranged in the chutes. After the concrete pouring is completed and the concrete is initially formed, the hanging formwork device needs to be disassembled. The usual operation is to use a lifting machine to lift the hooks at the four corners of the hanging formwork device through ropes. Because the hanging plate frame is clamped with the concrete poured on the surrounding sides, it is necessary to ensure that the four sides are lifted at the same time so as not to damage the concrete that is not fully formed. At this time, a greater force is required to pull the four hooks. This operation method requires a very high level of experience for the lifting machine operator. If you are not careful, it will cause irreparable damage to the poured concrete, affect the bearing capacity of the overall structure, and cause major safety hazards. This device is provided with several groups of chutes on the outer peripheral wall of the hanging plate frame, and a slide plate is arranged in the slide plate. When the concrete pouring is completed, the worker pulls out the slide plate. Because the width of the slide plate is limited, this operation can be completed manually. After the slide plate is taken out, the hanging plate frame is in a semi-contact state with the concrete of the structural beam. At this time, the lifting machine can easily lift the hanging formwork device to achieve the effect of rapid demolding. The bottom edge of the slide plate is kept flush with the bottom edge of the hanging plate frame, or shorter than the height of the hanging plate frame. This demolding method can quickly demold the mold, shorten the construction period, and will not affect the solidification strength of the concrete. The slide plate is an L-shaped plate, which is convenient for workers to hold during operation. It can also be other structures. The technical solutions of installing handles for easy grasping are all within the scope of protection of this application.

[0048] This utility model is used in the GEM housing construction project in Penang, Malaysia. The project is a super high-rise building with a total of 4 towers, Type A and Type B towers. Each tower has 29 standard floors. The Type A tower has 17 bathrooms on each floor, and the Type B tower has 16 bathrooms on each floor. It can be seen that the total number of bathrooms on the standard floors of the four towers is 1914.

[0049] Taking conventional hanging formwork as an example for economic analysis, the size of each bathroom is calculated as 1500×3000mm. A conventional hanging formwork for a bathroom requires a square wood length of about 21m. The frequency of square wood use is calculated based on 10 floors. During the entire construction period, each bathroom needs to consume 2.1m of square wood. It takes 0.5 man-days to install a conventional hanging formwork and 0.1 man-days to remove a conventional hanging formwork. The unit price of square wood is 3MR / m, and the unit price of labor is 120MR / man-day. The cost of using conventional hanging formwork for all bathrooms is 2.1m / piece × 1914 pieces × 3MR / m + 0.6 man-days / piece × 1914 pieces × 120MR / man-day = 149822MR.

[0050] Taking the hanging formwork device as an example for economic analysis, the size of each bathroom is calculated according to 1500×3000mm. A bathroom hanging formwork device requires a hanging plate (100×50×2mm square steel) with a length of 9m, a corner brace (50×50×3mm angle iron) with a length of 2.8m, a beam (75×75×5mm angle iron) with a length of 9.2m, 8 pads (150×100×2.5mm iron plate), and 4 hooks. The total weight of each hanging formwork device is about 110kg. It takes 2 working days to weld each hanging formwork device, and it takes a total of 0.1 working days to install and dismantle a device. The unit price of steel is 5000MR / T, and the unit price of labor is 120MR / working day. The cost required for using this hanging mold device in all bathrooms is 0.11T / piece × 5000MR / T × 66 pieces + 2 working days / piece × 120MR / working day × 66 pieces + 1914 pieces × 0.1 working day / piece × 120MR / working day = 75108MR.

[0051] In summary, after economic benefit analysis and comparison, the use of this hanging formwork device for construction will save approximately 74714MR. At the same time, after the construction is completed, the hanging formwork device can be recycled for a second time, with obvious economic benefits.

Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention. The above are only preferred implementations of the present invention.
