Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a bathroom hanging formwork. Background Art

[0002] The construction steps of the traditional drop-down bathroom are: first, smooth the part of the base that contacts the bathroom structure with cement mortar; then waterproof the base, install the bottom reinforcement of the lifting plate and various pipes; finally, pour concrete. After that, lay the waterproof layer, insulation layer and surface floor tiles.

[0003] The traditional formwork method mainly relies on wood as a supporting material. However, due to its natural material characteristics, wood is easily affected by factors such as environmental humidity and temperature, which makes the rigidity and flatness easily change. This change often causes the formwork to deform during the formwork process, thus affecting the quality of the project. In addition, the manufacture of wood is relatively cumbersome and requires special customization. It is easy to be damaged during use and has a large loss, which undoubtedly increases the material cost of the construction company. At the same time, the traditional formwork method has certain defects in the treatment of the inner corner of the drop plate, and workers with certain experience are required to manually use cement to make an arc at the inner corner. Due to manual operation, the arc surface is prone to roughness, skewness and unevenness, and it is difficult to completely seal the inner corner. It is easy to accumulate water during later use, resulting in leakage on the board surface. This not only affects the aesthetics of the building, but also may pose a potential threat to the structural safety of the building.

[0004] The bathroom drop-down formwork designed in the above manner has the following shortcomings, in other words, the technical problems to be solved by the present invention: the arc at the inner corner of the formwork needs to be manually processed for secondary processing, the operating error is large and cannot ensure density and flatness, leakage is prone to occur, and traditional molds are not easy to produce and install, and are difficult to transport and prone to wear and tear.

[0005] In summary, there is an urgent need for a bathroom hanging mold that is easy and fast to process, has high strength, and does not require manual processing of the curved surface at the inner corner of the template to solve the shortcomings of the existing technology. Utility Model Content

[0006] The utility model provides a bathroom hanging formwork, which is assembled on-site using common engineering materials and waste materials in a construction site, and an arc structure is added to the formwork frame, so that: 1. The arc structure allows the arc at the inner corner of the bathroom to be naturally formed after the formwork is dismantled, without the need for secondary processing by workers; 2. The naturally formed arc-shaped inner corner is dense and smooth, eliminating the problem of large errors and low efficiency caused by manual operation; 3. Production and installation only require on-site processing using common construction materials, which is more convenient than wooden molds, saves transportation costs, and can be put into use on a large scale.

[0007] The specific technical solutions adopted by the utility model to solve the above technical problems are as follows:

[0008] An embodiment of the present specification provides a bathroom hanging formwork, which is arranged on the structural surface of a sunken bathroom, and includes: a formwork fixing member, a formwork installation portion and positioning ribs, and is characterized in that: the formwork fixing member includes a supporting portion and a shaping portion connected to the supporting portion; the formwork installation portion includes a tensioning screw and a mounting angle steel, which are used to fix two adjacent formwork fixing members.

[0009] The added shaping part enables the bathroom structural surface to naturally form an arc-shaped inner corner after the concrete is poured, eliminating the need for secondary processing by workers and achieving high quality and small errors.

[0010] As a further preferred solution, the support portion is a long strip of angle steel; and the shaping portion is an arc surface with a fan-shaped cross-section and the same length as the support portion.

[0011] As a further preferred solution, the shaping portion protrudes outward and is welded to the supporting portion.

[0012] As a further preferred solution, there are multiple formwork fixing members, and they are respectively arranged corresponding to each edge of the structural surface.

[0013] As a further preferred solution, the tension screws and the installation angle steels are respectively welded to two adjacent formwork fixing members.

[0014] As a further preferred solution, the tension screw rod passes through the mounting angle steels on the adjacent formwork fixing members and is tightened so that the two adjacent formwork fixing members are closely fixed.

[0015] As a further preferred solution, the positioning ribs are welded to the bathroom beam stirrups while maintaining the same height relative to the bathroom structural surface.

[0016] As a further preferred solution, the formwork fixing member is placed horizontally on the positioning rib.

[0017] As a further preferred solution, the positioning bars are provided at the beam stirrups corresponding to the two ends and the midpoint of each edge of the bathroom structural surface.

[0018] The main beneficial effects of the above technical solution are:

[0019] 1. The added arc shaping part allows the arc structure at the inner corner of the bathroom to be naturally formed after the formwork is removed, without the need for secondary processing by workers, thus improving construction efficiency and quality;

[0020] 2. The arc-shaped inner corners naturally formed by the pre-set formwork structure are dense and smooth after concrete pouring. The arc surface formed in one time is obviously better than the result of manual secondary operation splicing, which eliminates the problem of large errors and low efficiency caused by manual operation;

[0021] 3. Production and installation only require the use of common construction materials such as discarded angle steel and steel pipes for on-site processing, which is more convenient than wooden molds and saves transportation costs.

[0022] Further or more detailed beneficial effects will be described in detail in conjunction with specific examples in the specific implementation manner. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the specific implementation of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the implementation of the utility model.

[0030] A bathroom hanging mold, such as Figure 1 As shown, it is arranged on the structural surface of the sunken toilet, and is used for accurate positioning when pouring concrete on the sunken floor of the toilet, and is convenient for construction. The toilet hanging formwork in this embodiment includes: a formwork fixing member 1, a formwork installation portion 2 and positioning ribs, and is characterized in that the formwork fixing member 1 includes a support portion 11 and a shaping portion 12 connected to the support portion; the formwork installation portion 2 includes a tensioning screw 21 and a mounting angle steel 22, which are used to fix two adjacent formwork fixing members 1.

[0031] Specifically, Figure 2 As shown, the bathroom hanging formwork in this embodiment includes a formwork fixing member 1, which is composed of a support portion 11 and a shaping portion 12. The support portion 11 is a long strip of angle steel, and the shaping portion 12 is a circular arc surface with a fan-shaped cross section and the same length as the long strip of angle steel. The long sides of the two correspond to each other, and the arc surface of the shaping portion 12 is welded outwardly to the opening of the angle steel of the support portion 11, so that the shaping portion after welding protrudes outward relative to the angle steel.

[0032] In this embodiment, the support part 11 selects 6mm*6mm equilateral right angle steel, and then selects a steel pipe with a diameter of more than 43.5mm, and cuts its 1 / 4 arc surface as the shaping part. The equilateral right angle steel has a stable structure and is easy to match most bathrooms where the wall and the ground are at right angles, and it matches the 1 / 4 arc surface more closely. Right angle steel and steel pipes are easy to obtain at construction sites, and are easy to cut and process, and can be applied to more construction situations. In addition, the steel cutting process is relatively mature, and the formwork fixings are easy to achieve accurate size, horizontal and vertical.

[0033] In other embodiments, the shape and size of the support portion 11 and the shaping portion 12 can also be adjusted according to actual conditions: for example, the support portion 11 can be made of angle steel with one side longer and the other shorter to match the elliptical arc surface of the shaping portion 12; or the support portion 11 can be made of steel frame structures with other angles to match the structural surface trend of the bathroom. The differences in structure or size are all to meet specific engineering needs or to make full use of existing materials on the construction site.

[0034] Furthermore, the bathroom hanging formwork also includes a plurality of the aforementioned formwork fixtures 1, and they are respectively arranged corresponding to each edge of the bathroom structural surface. The bathroom structural surface is the bathroom floor before the waterproof layer, floor tiles and other decorative works are laid, which is lower than the floor plane. After the bathroom hanging formwork is put in, the drop is filled by pouring concrete on the bathroom structural surface. Specifically, the formwork fixtures 1 correspond one-to-one to each edge of the bathroom structural surface, and the length of each formwork fixture 1 is consistent with the length of the corresponding edge of the structural surface, that is, the plurality of the aforementioned formwork fixtures 1 surround a formwork frame, and the formed frame is in the shape of the constructed bathroom structural surface. Specifically, as Figure 1 As shown, this embodiment uses four formwork fixtures 1 to surround a rectangular frame, which corresponds to the rectangular bathroom structure surface that is sunken in most cases. In other embodiments, multiple formwork fixtures can be surrounded along the structure surface shape into a trapezoid, polygon, etc. according to the actual bathroom design.

[0035] Furthermore, if Figure 1 As shown, a formwork mounting portion 2 is provided between each two adjacent formwork fixing members 1, and the tension screw rods 21 and the installation angle steel 22 in the formwork mounting portion 2 are respectively welded to two adjacent formwork fixing members. Specifically, the installation angle steel 22 is an angle steel with a length not greater than 1 / 4 of the length of the support portion 11, facing the inside of the frame surrounded by the formwork fixing members and welded to one of the formwork fixing members, and the tension screw rods 21 also face the inside of the frame and are welded to the adjacent formwork fixing members.

[0036] Furthermore, if Figure 3As shown, a through hole A is formed on the installation angle steel 22, and during welding, it is necessary to ensure that the unwelded end of the tension screw 21 passes through the through hole A. Since the diameter of the screw bolt is larger than the diameter of the through hole A, when the bolt on the tension screw 21 is tightened, the bolt generates a pulling force on the installation angle steel 22, so that the different formwork fixing parts respectively welded to the tension screw 21 and the installation angle steel 22 are close to each other, thereby being firmly fixed.

[0037] In this embodiment, four formwork fixtures 1 are surrounded to form a rectangular frame, and formwork mounting parts 2 are provided at the four inner corners of the rectangular frame. The tension screws 21 and the mounting angle steels 22 are respectively welded vertically to their formwork fixtures, so that the rectangular structure formed is stable and the formwork fixtures are firmly connected to each other. In some embodiments, the tension screws 21 and the mounting angle steels 22 can also be welded to their formwork fixtures at a certain angle, so that the formwork fixtures can be connected to each other to form a variety of shapes, matching the shape of the bathroom structure surface, and the pulling force generated into the frame when the bolts of the tension screws 21 are tightened can achieve a stable fixation of frames of various shapes.

[0038] Furthermore, in some embodiments, a connecting gasket may be added between the two formwork fixtures to enable the two formwork fixtures to be tightly connected. Specifically, since concrete needs to be poured after the formwork fixtures are laid on the structural surface of the bathroom, in order to prevent the concrete from overflowing from the formwork mold, a connecting gasket is provided at the connection between every two formwork fixtures to fill the gap at the connection. In this embodiment, a rubber gasket is used, which has good ductility and elasticity, and can cope with changes in various construction environments, making the gap smaller and the connection tighter, thereby reducing the problem of slurry running and leakage at the joints. The connecting gasket may also be made of other materials with excellent waterproof properties.

[0039] Furthermore, there are multiple positioning bars, and the positioning bars are welded to the bathroom beam stirrups at the same height relative to the bathroom structural surface. The bathroom beam stirrups are arranged in a ring above the structural surface, and one end of the multiple positioning bars is welded to the ring beam stirrups at the same height, and the other end is horizontally directed to the inside of the bathroom space, so that all the positioning bars are located in a horizontal plane parallel to the bathroom structural surface.

[0040] Furthermore, the said positioning ribs are provided at the beam stirrups corresponding to the two ends and the midpoint of each side of the bathroom structural surface, and the formwork fixtures are placed horizontally on the said positioning ribs. Each formwork fixture corresponds to an edge of the bathroom structural surface. In order to make the frame surrounded by the formwork fixtures remain horizontal and not tilted when placed in the bathroom structural surface, positioning ribs are provided at the two ends and the midpoint of each edge of the beam stirrups to bear the formwork fixtures; the two ends and the midpoint of the formwork fixtures are placed horizontally on the positioning ribs to achieve balance and stability. In this embodiment, the positioning ribs are made of steel bars with a diameter of 6mm, and can also be made of materials such as angle steel and steel pipes commonly used on the construction site. The length of the positioning ribs is not less than 65mm. It is necessary to ensure that the length of the positioning ribs is greater than the diameter of the forming portion so that the formwork fixtures can remain stable when placed.

[0041] In some embodiments, in addition to the two ends and the midpoint, more positioning bars can be set at the same height of the beam stirrups to achieve higher positioning accuracy, thereby ensuring that the bathroom floor cast after the formwork is erected is smoother.

[0042] Specifically, in this embodiment, the bathroom formwork is suitable for the following construction process:

[0043] S1. Use common materials and waste materials on the construction site to process and install the above-mentioned bathroom hanging mold according to the actual bathroom conditions;

[0044] S2. Determine the required installation height of the hanging formwork and weld each positioning reinforcement to the bathroom beam stirrups;

[0045] S3. Place the connected and installed formwork fixings horizontally on the positioning ribs;

[0046] S4. Use concrete pouring, first pour the ground outside the hanging formwork until it is level with the top of the hanging formwork;

[0047] S5. Then pour the structural surface in the hanging formwork until it is flush with the bottom of the hanging formwork;

[0048] S6. After pouring is completed, confirm that the concrete strength has reached the standard before removing the formwork: loosen the tension screws in the formwork installation part, release the tension of the tension screws, and remove the formwork fixings that are no longer closely connected one by one.

[0049] After removing the mold, the effect of the bathroom is as follows Figure 4 As shown. Since the shaping part protrudes outward, a circular arc surface will naturally be formed at the inner corner of the bathroom when pouring the outer floor of the bathroom hanging formwork, and the inside of the hanging formwork is poured until it is flush with the bottom of the hanging formwork, so that the circular arc surface and the structural surface after demolding are smooth, continuous, high in strength, and the curved surface is flat and has good waterproof performance.

[0050] The beneficial effects that this embodiment may produce include:

[0051] 1. The arc structure contained in the formwork allows the arc to be naturally formed at the inner corner of the bathroom after the formwork is removed, without the need for manual secondary processing, greatly saving labor costs; the naturally formed arc inner corner is dense and smooth, eliminating the problem of large errors and low efficiency caused by manual operation.

[0052] 2. After the traditional formwork system is constructed, before the waterproof coating, secondary mortar filling is required to prevent the coating from hollowing out at the inner corner of the drop plate, making it difficult to construct, and causing water accumulation after long-term use. However, the mortar cannot reach the same strength as the main structure after filling, and it is easy to loosen after drying, eventually destroying the waterproof coating layer. The arc-shaped inner corner formed in this embodiment is integrally formed, and the overall structure is smooth and continuous, which can well achieve the purpose of convenient construction and good waterproof effect.

[0053] 3. Production and installation only require on-site processing using common construction materials, which makes production and demoulding more convenient and saves transportation costs. It can be reused and put into large-scale application.
