AI Technical Summary
During the construction of existing construction, the cast-in-place concrete beam formwork is prone to leakage at joints during construction, and there is a lack of anti-leakage treatment, which affects the curing of concrete.
A leak-proof slurry beam formwork was designed. By setting a plate and tape between the beam side formwork and the beam bottom formwork, the tape consists of non-woven geotextile and high-water absorption resin, and dense permeable holes are set on the surface of the template to ensure that the cement particles do not pass through.
It realizes that there is no leakage of slurry during concrete pouring, and the water absorption and expansion effect of high-absorbing resin is closely blocked to ensure the anti-leakage effect of the template, and at the same time, it plays a role of moisturizing and maintenance with mold.

Abstract
Description
Technical Field
[0001] The utility model relates to a leak-proof beam formwork, belonging to the technical field of building construction. Background Art
[0002] At present, in the building construction in China, the formwork fixing tools for cast-in-place concrete beams basically use traditional square timbers. During the formwork construction process, the wood needs to be cut according to the size of the beam first, and then the wood is nailed together with nails, etc. to play the role of fixing the formwork.
[0003] CN215948908U discloses a clamping device for a beam formwork structure. A clamping frame sleeved on the beam formwork structure is formed by a pair of clamping members and corresponding supporting rods to clamp and fix the beam formwork structure. There is no need to penetrate tie bolts on the side formwork of the beam, which is convenient for installation, improves the construction efficiency and speeds up the construction progress; however, the side formwork and bottom formwork of the beam are not provided with anti-leakage treatment. During the construction pouring process, the beam formwork is often easily affected by the vibration force of the vibrating rod and the pressure of the concrete, resulting in the phenomenon of slurry leakage at the joints. At the same time, the maintenance of the concrete is also very important. Summary of the Utility Model
[0004] In order to solve the above problems existing in the prior art, the utility model provides a leak-proof beam formwork, which is convenient for transportation and can ensure no slurry leakage during concrete pouring.
[0005] The technical solution of the utility model is as follows:
[0006] A leak-proof beam formwork includes two side formworks of the beam and a bottom formwork of the beam. The two side formworks of the beam are rotatably connected to both sides of the bottom formwork of the beam. The leak-proof beam formwork further includes beam angle fixing parts for fixing the side formworks of the beam and the bottom formwork of the beam; a strip is arranged inside the two side formworks of the beam and the bottom formwork of the beam, and the strip connects the side formworks of the beam and the bottom formwork of the beam into a whole; the strip includes non-woven geotextile and superabsorbent resin, and the superabsorbent resin is arranged inside the non-woven geotextile.
[0007] Among them, the beam angle fixing part includes an angle steel and a bolt. The angle steel is fixedly installed at the connection of the side formwork of the beam and the bottom formwork of the beam and is fixed by the bolt.
[0008] Among them, the surfaces of the side formworks of the beam and the bottom formwork of the beam are provided with dense water-permeable holes, and the water-permeable holes are smaller than the size of cement particles.
[0009] The utility model has the following beneficial effects:
[0010] The utility model is provided with a strip, which is composed of non-woven geotextile and superabsorbent resin. During production, it is embedded as an interlayer in the side formwork and bottom formwork of the beam, and the side formwork of the beam can rotate and fold relative to the bottom formwork, facilitating the transportation and installation of the formwork as a whole. At the same time, the superabsorbent resin can ensure that there is no leakage of concrete during pouring and can also play a role in maintaining moisture with the formwork.

[0017] The following will combine the drawings and specific embodiments to elaborate on the utility model in detail.
[0018] Please refer to Figures 1 to 4 , the utility model provides a technical solution:
[0019] A leak-proof beam formwork includes beam side formwork 1, beam bottom formwork 2, beam corner fixing parts 3, and strip 4. Both sides of the two beam side formworks 1 and the beam bottom formwork 2 are rotatably connected through rotating shafts. The strip 4 is composed of non-woven geotextile 41 and superabsorbent resin 42, and is embedded as an interlayer in the beam side formwork 1 and the beam bottom formwork 2 during manufacturing to connect the beam side formwork 1 and the beam bottom formwork 2 into a whole, enabling the beam side formwork 1 to rotate and fold relative to the beam bottom formwork 2 and also being able to be transported and installed as a whole. The rotating shafts and the strip 4 are arranged staggered without interference. During the installation process, first rotate the beam side formwork 1 to an angle perpendicular to the beam bottom formwork 2, and then use the beam corner fixing parts 3 to fix the bottom corners. The beam corner fixing parts 3 are composed of angle steel and bolts. Since there is the strip 4 connecting at the included angle between the beam side formwork 1 and the beam bottom formwork 2, when the slurry flows through the gap at the included angle, the superabsorbent resin 42 can absorb water and expand to more tightly block the gap. On the other hand, the strip 4 is arranged at a position close to the inner surfaces of the beam side formwork 1 and the beam bottom formwork 2. At the same time, there are dense water-permeable holes on the inner surfaces of the beam side formwork 1 and the beam bottom formwork 2. On the premise that cement particles cannot pass through, the superabsorbent resin 42 in the strip 4 releases water through the non-woven geotextile 41, thus achieving the effect of curing the concrete structure.

Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
