Description

Technical Field

[0001] This application relates to the field of building technology, and in particular to a device for one-time casting and forming of the arc corner of a lowered slab room. Background Technology

[0002] In the construction industry, if rooms with water, such as kitchens and bathrooms, adopt the same-floor drainage system, a lowered slab must be installed in the structure. A lowered slab refers to reducing the structural elevation of the floor slab or roof slab. In other words, the floor of the room with water will sink as a whole, forming a sunken "hidden box" structure, which will bring more corners that can cause sewage to stagnate.

[0003] To prevent sewage stagnation in the corners, the corners of rooms with water need to be rounded to form an arc structure. In traditional construction, this is done by hand with cement mortar after the concrete has been poured and cured. This process is quite cumbersome and inconvenient for workers. In addition, when workers apply mortar by hand, it is difficult to make the arc uniform, which can easily lead to unevenness or uneven thickness, creating a risk of leakage. This increases the possibility of water seepage in the corners and has obvious shortcomings. Utility Model Content

[0004] To reduce the possibility of water seepage at the inside corner and improve the convenience for workers during construction, this application provides a device for one-time casting and molding of the arc corner of a lowered slab room.

[0005] The technical solution of the one-time casting molding device for the arc corner of a drop-slab room provided in this application is as follows:

[0006] A device for one-time casting and forming of arc corners in a lowered slab room includes a hanger with four surrounding panels. The four surrounding panels are spliced ​​together to form a rectangular frame. The four surrounding panels are set on the hanger. Each surrounding panel has an arc base component at its end away from the hanger. The arc base component includes an angle steel, and an arc-shaped tube is welded to the angle steel.

[0007] By adopting the above technical solution, an arc-shaped pipe welded with angle steel is set at the end of the enclosure panel, which directly serves as the arc boundary of the template, forming a one-time casting model for the arc corner. When casting the inside corner of the room with water, the device is suspended to the designed position of the lowered plate. The enclosure panel frame limits the boundary of the lowered plate, and the arc pipe is aligned with the inside corner. In this way, the arc pipe abuts against the surface of the inside corner, eliminating the need for a separate second round of arc coating. This improves the convenience of construction for workers and avoids water seepage caused by uneven coating due to manual work, reducing the possibility of water seepage at the inside corner.

[0008] Optionally, one end of the enclosure is detachably connected to the hanger via a connecting assembly, and the other end is detachably connected to the arc-shaped base via a connecting assembly.

[0009] By adopting the above technical solution, the connection components enable the splicing of the hanger, the arc base component, and the enclosure, making it easier for workers to replace the arc base component of different specifications according to the size of the lowered plate, thus improving the versatility of the device. After the pouring is completed, the connection components allow workers to quickly remove the enclosure and the arc base component, facilitating cleaning and reuse, and improving construction efficiency.

[0010] Optionally, the connecting assembly includes a connecting column, and the opposite end faces of the surrounding plate are provided with connecting holes that slide with the connecting column. The end of the hanger and the angle steel are provided with through holes for inserting the connecting column. Fasteners are provided on the connecting column, and the connecting column is fixed in the connecting hole by the fasteners.

[0011] By adopting the above technical solution, during connection, the worker inserts the connecting column into the connection hole of the enclosure and the through hole of the hanger or angle steel. Then, the connecting column is fixed in the connection hole and through hole with fasteners to achieve the connection between the hanger or angle steel and the enclosure. During disassembly, the fasteners are removed first, and then the connecting column is pulled out from the connection hole and through hole to achieve the separation between the hanger or angle steel and the enclosure.

[0012] Optionally, the fastener is a fastening plate, and the connecting post has a fastening groove that slides with the fastening plate. The fastening plate has an inclined surface that is inclined from top to bottom along the insertion direction of the fastening plate. When the fastening plate is inserted into the fastening groove, the outer surface of the fastening plate is in close contact with the inner surface of the fastening groove.

[0013] By adopting the above technical solution, after the connecting column is placed inside the connecting hole and through hole, the worker inserts the fastening plate into the fastening groove. As the fastening plate slides in, the outer surface of the fastening plate and the inner surface of the fastening groove gradually fit tightly together. Due to the inclined structure of the inclined surface, the clamping force will be evenly distributed along the axial direction to avoid local stress concentration. At the same time, as the insertion depth increases, the friction gradually increases, forming a self-locking effect to prevent the fastening plate from accidentally coming out during construction, ensuring that the connecting column is firmly fixed in the connecting hole and preventing loosening or displacement.

[0014] Optionally, the fastener is a pin rod, and the connecting post has a pin hole that slides with the pin rod. One end of the pin rod is provided with a gripping block, and the other end is threaded with a locking nut. When the pin rod is inserted into the pin hole, the opposite end faces of the gripping block and the locking nut abut against the outer surface of the connecting post.

[0015] By adopting the above technical solution, during installation, the worker holds the gripping block to insert the pin rod into the pin hole, and then tightens the locking nut on the pin rod, thus limiting the pin rod and preventing it from coming out of the pin hole. During disassembly, the worker unscrews the locking nut from the pin rod, then pulls the gripping block to remove the pin rod, and then removes the connecting post from the connecting hole and through hole. This design enables convenient installation of fasteners, avoids the need for workers to expend excessive force to remove fasteners, and further improves the convenience of worker operation.

[0016] Optionally, multiple connecting holes are provided on the enclosure plate, and the multiple connecting holes are evenly spaced.

[0017] By adopting the above technical solution, the setting of multiple connection holes makes it easier for workers to replace different specifications of hangers and arc base components according to the size of the lowering plate, further improving the versatility of the device.

[0018] Optionally, each of the enclosure panels has multiple protruding ridges on the surface opposite to the construction surface.

[0019] By adopting the above technical solution, the convex ridges improve the structural strength of the enclosure, prevent the enclosure from sinking inward during construction, and ensure stability during construction.

[0020] Optionally, the enclosure is made of aluminum alloy.

[0021] By adopting the above technical solutions, aluminum alloys have high strength and hardness, can withstand the pressure of concrete pouring, are not easily deformed or damaged, have good corrosion resistance, can adapt to humid and variable construction environments, extend the service life of the enclosure, and reduce the frequency of replacement.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This application sets up a hanger, a surrounding panel, and an arc base component. An angle steel welded arc tube is set at the end of the surrounding panel, which directly serves as the arc boundary of the template, forming a one-time casting model for the arc corner. When casting the inside corner of a room with water, the device is suspended to the design position of the lowered plate. The surrounding panel frame defines the lowered plate boundary, and the arc tube is aligned with the inside corner. In this way, the arc tube abuts against the surface of the inside corner, eliminating the need for a separate second round of arc coating. This improves the convenience of construction for workers and avoids water seepage caused by uneven coating due to manual work, reducing the possibility of water seepage at the inside corner.

[0024] 2. This application incorporates a connecting component, which enables the splicing of the hanger, the arc base component, and the surrounding plate. This allows workers to easily replace the arc base component with different specifications according to the size of the lowered plate, improving the versatility of the device. After pouring, the connecting component allows workers to quickly remove the surrounding plate and the arc base component, facilitating cleaning and reuse, and improving construction efficiency.

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0032] Example 1

[0033] This application discloses a device for one-time casting and molding of the arc corner of a lowered slab room.

[0034] Reference Figure 1 A device for one-time casting and forming of arc corners in a lowered slab room includes a hanger 1. In this embodiment, the hanger 1 is made of two angle steel plates welded together. The hanger 1 is cross-shaped and is used to connect with the hook part of the lifting device.

[0035] Referring to the figure, each of the four corners of the hanger 1 is detachably connected to a surrounding panel 3 via a connecting component 2. The four surrounding panels 3 are spliced ​​together to form a rectangular frame. The surrounding panels 3 are made of aluminum alloy, which has high strength, hardness and internal corrosion resistance, is not easily deformed or damaged, can adapt to humid construction environments, and extends the service life of the surrounding panels 3.

[0036] Referring to the figure, each enclosure panel 3 has multiple protruding ribs 4 fixedly connected to the surface opposite to the construction surface. The protruding ribs 4 are integrally formed with the enclosure panel 3. The protruding ribs 4 improve the structural strength of the enclosure panel 3 and prevent the enclosure panel 3 from sinking inward during construction, thus ensuring the stability of the construction process.

[0037] Referring to the figure, the ends of the four enclosure plates 3 away from the hanger 1 are detachably connected to arc base components 5 via connecting components 2. The arc base components 5 include angle steel 51, and arc tubes 52 with arc-shaped structures are welded to both ends of the angle steel 51. In this embodiment, the arc tubes 52 are quarter-circular tubes. It should be noted that, depending on the depth of the designed lower plate, the number of angle steel 51 can be one or two. When two angle steel 51 are used, the ends of the two angle steel 51 are welded together in sequence.

[0038] Angle steel 51 is welded to the end of the enclosure panel 3 to form an arc-shaped pipe 52, which directly serves as the arc boundary of the template, forming a one-time casting model for the arc corner. When casting the inside corner of the room with water, the device is suspended to the lowering plate design position. The frame of the enclosure panel 3 defines the lowering plate boundary, and the arc pipe 52 is aligned with the inside corner. In this way, the arc pipe 52 abuts against the surface of the inside corner, eliminating the need for a separate second round of arc coating. This improves the convenience of construction for workers and avoids water seepage caused by uneven coating due to manual work, reducing the possibility of water seepage at the inside corner.

[0039] Reference Figure 1 The connecting component 2 includes a connecting column 21. The opposite end faces of the surrounding plate 3 are provided with connecting holes 31 that slide with the connecting column 21. The number of connecting holes 31 can be one or more to suit different construction scenarios. The end of the hanger 1 and the angle steel 51 are provided with through holes 6 for inserting the connecting column 21. The number of through holes 6 on the angle steel 51 corresponds one-to-one with the number of connecting holes 31 to improve the stability of the connection between the arc base component 5 and the surrounding plate 3. Fasteners 22 are provided on the connecting column 21, and the connecting column 21 is fixed in the connecting hole 31 by the fasteners 22.

[0040] Referring to the figure, the fastener 22 is a fastening plate 221. The connecting post 21 has a fastening groove 211 that slides with the fastening plate 221. The fastening plate 221 has an inclined surface (not shown in the figure). The inclined surface is inclined from top to bottom along the insertion direction of the fastening plate 221. When the fastening plate 221 is fixed inside the fastening groove 211, the outer surface of the fastening plate 221 is tightly fitted with the inner surface of the fastening groove 211.

[0041] During connection, the worker inserts the connecting post 21 into the connecting hole 31 of the enclosure plate 3 and the through hole 6 of the hanger 1 or angle steel 51. Then, the fastening plate 221 is inserted into the fastening groove 211. As the fastening plate 221 slides in, the outer surface of the fastening plate 221 and the inner surface of the fastening groove 211 gradually fit tightly together. Due to the inclined structure of the inclined surface, the clamping force will be evenly distributed along the axial direction to avoid local stress concentration. At the same time, as the insertion depth increases, the friction gradually increases, forming a self-locking effect to prevent the fastening plate 221 from accidentally coming out during construction, ensuring that the connecting post 21 is firmly fixed in the connecting hole 31 and preventing loosening or displacement.

[0042] During disassembly, workers drag fastener 22 to pull it out of the fastening groove 211, and finally remove the connecting column 21 from the connecting hole 31 and the through hole 6 to complete the disassembly. The setting of the connecting component 2 realizes the splicing between the hanger 1, the arc base component 5 and the surrounding plate 3, which makes it easy for workers to replace the arc base component 5 of different specifications according to the size of the lower plate, thus improving the versatility of the device. After the pouring is completed, the setting of the connecting component 2 allows workers to quickly remove the surrounding plate 3 and the arc base component 5, which is convenient for cleaning and reuse, thus improving construction efficiency.

[0043] The implementation principle of the one-time casting molding device for the arc corner of a lowered room according to the embodiment of this application is as follows: An angle steel 51 is set at the end of the surrounding plate 3 and an arc-shaped pipe 52 is welded to it, which directly serves as the arc boundary of the template to form a one-time casting model for the arc corner. When casting the inside corner of the room with water, the device is suspended to the lowered plate design position. The frame of the surrounding plate 3 defines the lowered plate boundary, and the arc pipe 52 is aligned with the inside corner. In this way, the arc pipe 52 abuts against the surface of the inside corner, eliminating the need for a separate second round of arc coating. This improves the convenience of workers during construction and avoids water seepage caused by uneven coating due to manual labor, reducing the possibility of water seepage at the inside corner.

[0044] Example 2

[0045] The difference between this embodiment and Embodiment 1 is that the fastener 22 is a pin 222, and the connecting post 21 has a pin hole 212 that slides with the pin 222. The pin hole 212 is a round hole. One end of the pin 222 is fixedly connected to a gripping block 2221 that is easy for a person to hold. The end of the pin 222 away from the gripping block 2221 is threadedly connected to a locking nut 2222. The outer surface of the locking nut 2222 has multiple anti-slip grooves evenly distributed circumferentially (not shown in the figure). When the pin 222 is inserted into the pin hole 212, the opposite end faces of the gripping block 2221 and the locking nut 2222 abut against the outer surface of the connecting post 21.

[0046] The implementation principle of Example 2 is as follows: During installation, the worker holds the gripping block 2221 and inserts the pin 222 into the pin hole 212. Then, the locking nut 2222 is tightened onto the pin 222, thus limiting the pin 222 and preventing it from coming out of the pin hole 212. During disassembly, the worker unscrews the locking nut 2222 from the pin 222, then pulls the gripping block 2221 to remove the pin 222. The connecting post 21 is then removed from the connecting hole 31 and the through hole 6. This arrangement facilitates the installation of the fastener 22, avoids the worker having to exert a lot of force to remove the fastener 22, and further improves the ease of operation for the worker.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
