Description

Technical Field

[0001] This utility model belongs to the field of building construction, specifically relating to a suspended reusable trumpet-shaped mold device, which is suitable for casting structural columns in frame shear wall structures of industrial and civil buildings. Background Technology

[0002] Currently, in China, interior partition walls and enclosure walls in building construction projects are mostly constructed using masonry blocks. The formwork and pouring of structural columns are a crucial part of masonry engineering. Under current construction techniques, structural column construction is typically done in-situ. The specific process is as follows: after the structural column reinforcement is tied and the adjacent masonry is completed, the formwork is immediately installed. After the concrete is poured through the flared end, the formwork is removed once the concrete reaches a certain strength for demolding. The formwork is then reused. To ensure the density of the concrete at the top of the structural column, the concrete inside the flared end is usually poured to the top elevation of the column. After removing the formwork, the excess concrete in the flared end is removed. During the construction period of the structural column, the erection of the flared end formwork and the removal of excess concrete often consume significant time, labor, and material costs.

[0003] Chinese patent application number 202111074278.X discloses a standardized template structure for the flared end of a structural column. This flared end uses a vertically cut baffle to separate the notch from the conveying channel, preventing concrete in the pouring space from flowing back to the outside of the notch. This ensures that the structural column concrete is formed independently without excess protrusion, achieving a one-time molding and aesthetically pleasing result, effectively solving the problem of eliminating the need for chiseling the flared end. Chinese patent application number 202121093122.1 discloses a lightweight, modular, chiseling-free flared end pouring device for structural columns. This device consists of an aluminum alloy base with a pull-out baffle, a foldable flared end mold, and stainless steel U-shaped clamps for fixing, also solving the problem of eliminating the need for chiseling the flared end. While these two patents solve the chiseling problem after the flared end is poured, the reinforcement process is cumbersome, the individual processing cost is high, and the column cannot be immediately reused after pouring.

[0004] Chinese patent application number 201820760915.6 discloses a concrete top formwork casting structure for a structural column. It eliminates the need to chisel out the protruding concrete at the top inlet. During concrete pouring, the pressure of the concrete on the closing plate is borne not only by the closing screws but also by the hopper. The bottom of the hopper is connected to the hopper fixing timber by screws. The top of the hopper fixing timber has a sloping structure. The contact area between the hopper fixing timber and the hopper is small, and the connection is only by screws, which leads to problems of inconvenient fixing and unstable fixing. Summary of the Invention

[0005] To address the aforementioned problems in the existing technology, this utility model provides a fixed, stable, and easy-to-operate suspended reusable flared mouth mold device.

[0006] The purpose of this utility model is achieved in the following manner: a suspended reusable flared mold device, including a hanging ear, a casting flared mouth, a casting hinge plate, a backstop baffle, and a fastening protrusion. A hanging ear is connected to each of the two sides of the upper end of the casting flared mouth. A casting hinge plate is provided between the two side plates of the casting flared mouth. The casting hinge plate is hinged to the bottom edge of the casting flared mouth. A U-shaped backstop baffle is provided on the outer side of the two side plates of the casting flared mouth and the casting hinge plate. A fastening protrusion is provided on the side plate of the casting flared mouth near the finished casting surface.

[0007] The casting flared opening includes a left side, a left side plate, a bottom side, a right side, and a right side plate. The left side, bottom side, and right side are coplanar. The left side and the left side plate are bent together as one piece, and the right side and the right side plate are bent together as one piece. The left side plate and the right side plate are wider at the top and narrower at the bottom, forming a flared opening shape together with the casting hinge plate.

[0008] The tilt angle of the cast hinge plate is 30°.

[0009] Push-pull handles are installed on the cast-in-place hinge plates.

[0010] The fixed protrusion is 3mm away from the finished casting surface.

[0011] The upper ends of the left and right sides are bent to form bent sections, and the lugs are welded to the bent sections for fixation.

[0012] Compared to existing technologies, this utility model discloses a suspended, reusable trumpet-shaped mold device with a simple structure and easy installation. The device can be easily and quickly suspended from the tops of the square timbers on both sides of the structural column formwork using hanging lugs, ensuring a secure fixation. After the structural column is poured, it can be removed and reused multiple times. The mold body is made of steel plate, making it lightweight, strong, and rigid, less prone to deformation during construction, and meeting on-site requirements. It eliminates the need for chiseling at the trumpet-shaped opening, avoiding concrete waste and reducing labor costs and material costs associated with later chiseling. Simultaneously, it eliminates potential quality issues and shortens the construction period of a single-layer masonry structure by 0.3 days. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention. After reading the contents of the present invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present invention.

[0019] like Figure 1-3 As shown, a suspended reusable flared mold device includes a hanging lug 1, a casting flared mouth 2, a casting hinge plate 3, a backstop baffle 4, and a locking protrusion 6. A hanging lug 1 is connected to each of the two sides of the upper end of the casting flared mouth 2. A casting hinge plate 3 is provided between the two side plates of the casting flared mouth 2. The casting hinge plate 3 is hinged to the bottom edge of the casting flared mouth 2. A U-shaped backstop baffle 4 is provided on the outer side of the two side plates of the casting flared mouth 2 and the outer side of the casting hinge plate 3. A locking protrusion 6 is provided on the side plate of the casting flared mouth 2 near the finished casting surface.

[0020] A further preferred embodiment is that the cast-in-place bell mouth 2 includes a left side 21, a left side plate 22, a bottom side 23, a right side 24, and a right side plate 25. The left side 21, bottom side 23, and right side 24 are coplanar. The left side 21 is integrally bent with the left side plate 22, and the right side 24 and right side plate 25 are integrally bent. The left side plate 22 and right side plate 25 are wider at the top and narrower at the bottom, forming a bell mouth shape together with the cast-in-place hinge plate 3. The cast-in-place bell mouth 2 can be made from a single piece of steel plate. For example, a 3mm thick rectangular steel plate can be selected, and a certain width of left and right sides and bottom edge can be reserved according to the working conditions. An isosceles triangle can be cut down from the midpoint of the top of the steel plate. One side of the cut steel plate is bent to the left to form the left side plate 22, and the other side is bent to the right to form the right side plate 25. Then, a cast-in-place hinge plate 3 is hinged to the bottom edge of the steel plate using a steel hinge 5. The hinge plate 3 is preferably made of 3mm thick steel plate. The dimensions of the hinge plate 3 should meet the enclosure space of the pouring bell mouth and the dimensions of the pouring opening of the structural column. Specifically, the width of the hinge plate 3 is slightly smaller than the base length of the cut-off isosceles triangle, and the length of the hinge plate 3 is equal to or less than the leg length of the cut-off isosceles triangle. There are 1-2mm gaps between the hinge plate 3 and the left side plate 22 and the right side plate 25, which can ensure that the hinge plate 3 can move within the left side plate 22 and the right side plate 25 without causing concrete leakage.

[0021] The hanging ear 1 is preferably made of L-shaped angle steel and welded to the upper end of the pouring bell mouth 2 as a whole. The length of the hanging ear 1 is determined according to the size of the structural column, such as 25*25*4mm angle steel. When the structural column formwork is installed and fixed, the angle steel is suspended from the top of the square timber on both sides of the structural column formwork by utilizing the gaps between the square timber, structural beam, and structural column formwork, as well as the structural characteristics of the angle steel itself. It can be removed when the concrete of the structural column has initially set.

[0022] The tilt angle of the poured hinge plate 3 is 30°. The 30° tilt angle allows the poured concrete to enter the pouring space smoothly and quickly.

[0023] A push-pull handle 7 is provided on the cast-in-place hinge plate 3. The push-pull handle 7 facilitates the opening and closing of the cast-in-place hinge plate 3.

[0024] The anti-reverse baffle 4 is made of 3mm thick and 20mm wide steel strips and is fixed to the outer sides of the casting funnel mouth enclosure by welding. When the mold is turned over and poured, the casting hinge plate 3 is easily rotated to more than 30° due to its own weight and the influence of concrete pouring. The anti-reverse baffle 4 is to prevent the casting hinge plate from rotating too much and losing its function.

[0025] The locking protrusion 6 is 3mm away from the finished concrete surface. The locking protrusion 6 is a limiting component protruding from the left or right side plate. After the concrete is poured, the poured hinge plate 3 closes inward, sealing the pouring opening cut into the structural column formwork. It is coplanar or nearly coplanar with the structural column formwork. At this time, the locking protrusion 6 limits its movement, preventing the poured hinge plate 3 from flipping outward under gravity. During manufacturing, both sides of the poured hinge plate 3 are ground smooth by 0.5mm to ensure that it can smoothly pass through the locking protrusion 6 when pushed inward after pouring. The locking protrusion 6 then secures the poured hinge plate 3.

[0026] The upper ends of the left side 21 and the right side 24 are bent to form bent portions 26, and the lug 1 is welded to the bent portions 26 for fixation. Furthermore, in order to improve the welding strength between the lug 1 and the main body of the casting bell mouth, a 25*4mm flat steel is bent into an L shape once and used as a connecting part between the lug 1 and the casting bell mouth to improve the welding strength.

[0027] Taking into account economic practicality, the steel hinge 5 and the push-pull handle 7 are made of ordinary components. The steel hinge 5 allows the hinge plate to be flipped during pouring to push the concrete to complete the pouring. The push-pull handle 7 serves to push and pull the pouring hinge plate during pouring and when it is turned over after pouring.

[0028] Work process: such as Figure 4 As shown, during the construction of the structural column, after the structural column reinforcement 12 is tied and the masonry walls 10 on both sides are completed, the structural column formwork 9, the square timber 8 on both sides, and the formwork fasteners are reinforced according to the normal construction process. At the finished surface of the pouring opening, a 150mm (width) * 200mm (height) piece of the structural column formwork 9 is cut off and discarded, leaving the pouring opening to meet the pouring requirements. The suspended reusable flared mold device of this utility model is suspended from the top of the square timber on both sides of the template by the hanging ears 1. The flared opening 2 and the pouring hinge plate 3 together form an enclosing space. Then, the pouring hinge plate 3 is fixed between the left and right side plates of the pouring flared opening 2 by the anti-reverse baffle 4, so that it will not open to a larger angle. Concrete is poured into the pouring opening through the enclosing space. When it is about to be poured to the bottom of the structural beam / slab 11, the pouring hinge plate 3 is flipped to push in the remaining concrete to make the top of the structural column compact. After the concrete has initially set, the hinge plate can be pulled open by the push-pull handle 7 to observe the concrete solidification and remove the mold for repeated reuse.

[0029] This utility model discloses a suspended, reusable trumpet-shaped mold device. It features a simple structure and easy installation. Using hanging lugs, the device can be easily and quickly suspended from the tops of the square timbers on both sides of the structural column formwork, ensuring a secure fixation. After the structural column is poured, it can be removed and reused multiple times. The mold body is made of steel plate, making it lightweight, strong, and rigid. It is not easily deformed during construction and meets on-site requirements. This eliminates the need for chiseling at the trumpet-shaped opening, avoiding concrete waste and reducing labor costs and material costs associated with later chiseling. It also eliminates potential quality issues and shortens the construction period of a single-layer masonry structure by 0.3 days.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
