Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a precast reinforced concrete formwork integral casting filter plate. Background Technology

[0002] As a core process in water treatment plants, the operation of filter beds directly affects the quality of the effluent from the water treatment plant. The filter heads and filter plates inside the filter bed are the key components of the filter bed. Currently, filter plates are divided into two types: precast filter plates and integral cast filter plates. Integral cast filter plates are further divided into castable and non-castable types.

[0003] Precast filter plates have drawbacks, including high transportation costs, and the joints between plates are prone to cracking and detachment after installation, affecting the airtightness of the filter plate. Furthermore, the block shape of precast filter plates disrupts the overall reinforcement of the filter tank, affecting its overall strength. The use of pre-embedded bolts for installation also poses potential strength issues. While integral casting of filter plates can address these drawbacks, it is more difficult and labor-intensive to construct. During casting, template deformation and grout leakage can occur, resulting in poor flatness and uneven thickness of the cast filter plates, which in turn affects the water and air distribution in the filter tank.

[0004] Therefore, there is an urgent need to design a precast reinforced concrete formwork filter plate for integral casting. Summary of the Invention

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] This utility model provides a precast reinforced concrete formwork integral casting filter plate, such as... Figure 1 As shown, it includes:

[0029] The base plate 1 has several screw holes spaced at equal intervals, and a pre-embedded component is threaded into each screw hole;

[0030] The embedded component includes a first embedded part 2 and a second embedded part 3; the first embedded part 2 is fixedly installed on the top surface of the base plate 1 by a first fixing part 4, and one end of the first fixing part 4 is threaded into a screw hole;

[0031] The first embedded part 2 and the second embedded part 3 are threadedly connected and their end faces abut against each other; a cap 5 is threadedly installed on the side of the second embedded part 3 away from the base plate 1.

[0032] The first embedded part 2 has a first extension ring 21 extending outward from both ends of its sidewalls, and a reinforcing ring 22 is also formed in the middle of the outer wall of the first embedded part 2; a first internal thread 23 is provided on one end of the inner wall of the first embedded part 2.

[0033] The first fastener 4 includes a fixing section, a connecting section, and a snap-fit ​​section; the end of the fixing section is provided with a first external thread 41, and the fixing section is fixedly connected to the snap-fit ​​section through the connecting section; the interface shape of the connecting section is funnel-shaped; the snap-fit ​​section is fixedly snapped onto one side of the first internal thread 23 of the first embedded part 2; the end of the fixing section is installed in the screw hole through the first external thread 41.

[0034] The second embedded part 3 has two side walls extending outward to form a second extension ring 31, and one end of the first embedded part 3 has an extension portion extending outward, with a second external thread 32 on the outer wall of the extension portion; the other end of the second embedded part 3 has a second internal thread 33 on the inner wall; the second embedded part 3 is threadedly connected to the first internal thread 23 of the first embedded part 2 through the second external thread 32, and the first extension ring 21 abuts against the end face of the second extension ring 31.

[0035] The cap 5 thread is installed inside the second internal thread 33.

[0036] The cap 5 is flush with the end face of the second embedded part 3.

[0037] This utility model prefabricates reinforced concrete templates according to the filter beam spacing and filter tank size. After prefabrication, the reinforced concrete templates are fully laid on the filter beams in the filter tank. The filter beams are pre-reserved with steel bars according to the filter plate reinforcement spacing. Steel bars are planted around the filter tank at the reinforcement positions of the secondary integrally cast filter plate. After the steel bars are added, the filter plate is integrally cast and the upper surface of the filter plate is pressed smooth to form an integrally cast filter plate.

[0038] In one embodiment of this utility model, the precast reinforced concrete formwork is integrally cast using a mold. The dimensions of the casting mold in this embodiment are 1070mm*940mm*70mm.

[0039] Furthermore, the mold material in this application can be steel or rigid plastic, and the reinforced concrete precast formwork requires a flat lower surface and a rough upper surface to facilitate better bonding during secondary pouring. The mold for the rough upper surface of the reinforced concrete precast formwork is a flat mold, and it is cast piece by piece.

[0040] In one embodiment of this utility model, the precast reinforced concrete template is made of a special mold with flat surfaces on both the top and bottom, using a vertical mold and a casting method of one out of ten.

[0041] Furthermore, special attention needs to be paid to the pouring and vibration of concrete when using a 1-out-10 vertical formwork. The thickness of the reinforced concrete precast formwork is set at 60mm-80mm. The number of filter heads per square meter and the gap size of the filter heads are determined according to the required opening ratio of the filter plates in the filter tank. Then, the first embedded parts 2 are arranged in a mesh according to the number of filter heads per square meter, and the first embedded parts 2 are fixed to the base plate 1 in a mesh shape with the first fixing parts 4. At this time, screw holes are opened on the base plate at the corresponding positions of the first embedded parts 2, and the inner diameter of the screw holes matches the outer diameter of the first external thread 41 at one end of the first fixing parts 4.

[0042] Furthermore, according to the filter tank process requirements, the number of filter heads arranged per square meter of filter plate is generally 36-64. After arranging the first embedded part 2, the side formwork of the grid-shaped precast reinforced concrete template is fitted on. After fixing the embedded part 2 and the side formwork, the reinforcement is arranged in a single layer bidirectional mesh according to the filter tank process strength requirements (using φ10 grade III threaded steel in a single layer bidirectional mesh arrangement); then C30 impermeable concrete is poured and cured for 24 hours. The formwork is then removed and the surface is placed flat in a dedicated curing area for curing and hardening, so that it can be used for future purposes.

[0043] Furthermore, based on the filter tank dimensions of the project, a matching precast reinforced concrete formwork is selected. First, according to the filter tank's process strength requirements and filter head spacing, φ12 grade III threaded steel bars are pre-installed on the filter beams, and air-leveling holes are pre-installed on the filter beams for leveling. After the leveled filter beams reach a certain hardness, the precast reinforced concrete formwork is fully laid. After the precast reinforced concrete formwork is fully laid, the flatness of the entire tank formwork is checked, ensuring there are no gaps between the formwork panels that could allow grout leakage. Then, one end of the second embedded part 3 is fixedly connected to the first embedded part 2, and the upper end of the second embedded part 3 is sealed with a cap 5. Finally, reinforcement is arranged in a single-layer, two-way mesh pattern according to the filter tank's process strength requirements.

[0044] Furthermore, before laying the precast reinforced concrete formwork, according to the filter tank process requirements and filter head spacing, drill φ12-φ16 holes with a depth of 150mm around the perimeter of the tank wall corresponding to the secondary casting reinforcement marks on the filter plate. After completing the above preparations, pour C30 impermeable concrete for secondary casting. After the secondary cast concrete is smoothed, polished, and hardened for 24 hours, remove the upper end of the second embedded part 3 and use a special plastic cover to cure the filter plate. Once it reaches more than 70% strength, the filter heads can be installed.

[0045] In one embodiment of this utility model, the side mold is rectangular, with the long side mold perpendicular to the bottom mold at 90°, and the wide side mold arranged in the same direction at a 45° angle to the bottom mold. This allows the precast reinforced concrete formwork to partially overlap when laid in the filter tank, thereby preventing grout leakage during secondary pouring.

[0046] In one embodiment of this utility model, the technical point of this template is to replace the non-removable plastic injection molded template or detachable precast template used in the prior art with a precast reinforced concrete template, thereby completing the integral casting of the filter plate. It also possesses the overall flatness and strength of an integrally cast filter plate. This avoids the problems associated with precast filter plates, such as high transportation costs, easy cracking and detachment of the joints between the plates after installation, affecting the airtightness of the filter plate; the block shape of the precast filter plate causing fragmentation of the reinforcement of the entire pool, affecting the overall strength of the filter plate; and the use of pre-embedded bolts for installation, which also poses potential installation strength risks.

[0047] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0048] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
