Description

Technical Field

[0001] This utility model relates to the field of bottom mold fixing technology, and in particular to a bottom mold fixing structure for irregular-shaped fair-faced beams. Background Technology

[0002] In modern architectural structures, designers are paying increasing attention to the aesthetic appeal of buildings. This has led to the emergence of a host of unique structural forms, among which exposed beams are increasingly being used in practical structures due to their high aesthetic value.

[0003] In the existing technology, some irregular structures are increasingly used in practice due to their special shapes. As a combination of the two, irregular fair-faced beam structures have higher requirements for construction technology. Since the bottom formwork is relatively easy to slide, and since irregular beams often have curved surfaces or non-standard inclination angles, the bottom formwork is more prone to slippage.

[0004] Based on this, a bottom formwork fixing structure for irregularly shaped fair-faced beams is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a fixing structure for the bottom formwork of irregularly shaped fair-faced beams, so as to solve the problems mentioned in the background art.

[0006] The technical solution of this utility model is: a fixing structure for the bottom formwork of an irregularly shaped fair-faced beam, including uprights, and further comprising:

[0007] The U-shaped support is fixedly installed at the top of the upright, and a wooden block is fixedly installed on the upper surface of the U-shaped support. The upper surface of the wooden block has multiple grooves.

[0008] The bottom mold body has multiple back ribs fixedly connected to its lower surface. The multiple back ribs are respectively adapted to the inner walls of the corresponding multiple grooves. Arc-shaped grooves are opened on both sides of the multiple back ribs.

[0009] A sleeve, wherein a spring is fixedly connected to the inner wall of the sleeve, and an arc-shaped clamp is slidably connected to the inner wall of the sleeve.

[0010] In some embodiments, a steel pipe is provided inside the U-shaped support, and a plurality of steel nails are provided on the wooden block, and the wooden block and the U-shaped support are fixedly connected by the steel nails.

[0011] In some embodiments, the surface of the arc-shaped clamp head is adapted to slide and connect with the inner wall of the sleeve, and the arc-shaped clamp head and the arc-shaped groove are elastically engaged.

[0012] In some embodiments, a second steel nail is provided on the back rib, and the bottom mold and the back rib are fixedly connected by the second steel nail.

[0013] Compared with existing technologies, the significant advantages of this invention are:

[0014] Firstly, this utility model features a U-shaped bracket installed at the top of the central pole, with nested steel pipes inside to enhance bending rigidity. The U-shaped bracket is secured to the timber with steel nails, forming a stable horizontal load-bearing platform. Multiple grooves are pre-made on the upper surface of the timber, with the groove spacing matching the back ribs, providing a precise positioning base for the bottom formwork.

[0015] Secondly, this utility model has arc-shaped grooves on both sides of the back rib, which dynamically engage with the arc-shaped clamps inside the sleeve. During installation, the back rib is pressed down, which causes the arc-shaped clamps to be squeezed inward, thus compressing the spring. When the back rib is in place, the spring rebounds and pushes the clamps into the arc-shaped grooves, forming a self-locking mechanism. This improves the stability of the bottom mold installation and further avoids the possibility of bottom mold slippage. Attached Figure Description

[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] This utility model provides an improved fixing structure for the bottom formwork of an irregularly shaped clear water beam. The technical solution of this utility model is as follows:

[0025] like Figures 1-4 As shown, a bottom formwork fixing structure for an irregularly shaped fair-faced beam includes a vertical pole 1, and also includes:

[0026] U-shaped support 2, U-shaped support 2 is fixedly installed at the top of the upright 1, and a wooden block 3 is fixedly installed on the upper surface of the U-shaped support 2. Multiple grooves 6 are opened on the upper surface of the wooden block 3.

[0027] The bottom formwork body 8 is usually made of formwork material (such as film-coated plywood, steel formwork or plastic formwork) that meets the requirements of fair-faced concrete. Its shape must be completely consistent with the design outline of the irregular fair-faced beam (including possible curved surfaces or inclination angles). Multiple back ribs 7 are fixedly connected to the lower surface of the bottom formwork body 8. The multiple back ribs 7 are respectively adapted to the inner walls of the corresponding multiple grooves 6. Arc grooves 12 are opened on both sides of the multiple back ribs 7.

[0028] The sleeve 9 has a spring 10 fixedly connected to its inner wall and an arc-shaped clamp 11 slidably connected to its inner wall.

[0029] like Figure 1 and Figure 3 As shown, in one embodiment, a steel pipe 5 is provided inside the U-shaped support 2. The steel pipe 5 serves as the main keel of the support device. In order to significantly enhance the bending stiffness and load-bearing capacity of the U-shaped support 2 and prevent it from being deformed under pressure, a steel pipe 5 is tightly nested in the inner cavity of the U-shaped support 2. Multiple steel nails 4 are provided on the wooden block 3. The wooden block 3 and the U-shaped support 2 are fixedly connected by the steel nails 4.

[0030] The surface of the arc-shaped clamp 11 is adapted to slide and connect with the inner wall of the sleeve 9, and the arc-shaped clamp 11 and the arc-shaped groove 12 are elastically engaged.

[0031] like Figure 4 As shown, in one embodiment, a steel nail 13 is provided on the back rib 7, and the bottom mold and the back rib 7 are fixedly connected by the steel nail 13.

[0032] The specific working method is as follows: First, erect the uprights 1 according to the construction plan, adjust their height and verticality to ensure consistent top elevation. Install and fix the U-shaped brackets 2 at the top of the uprights 1. Tightly nest the reinforcing steel pipes 5 into the inner cavity of the U-shaped brackets 2. Then, place the pre-made grooved timber 3 on the upper surface of the U-shaped brackets 2, and firmly nail the timber 3 to the U-shaped brackets 2 with steel nails 4. At this time, it is necessary to ensure that the position, direction, and spacing of all grooves 6 meet the design requirements, especially aligning with the direction of the irregular beam to be installed. On the lower surface of the bottom formwork body 8, fix the back ribs 7 firmly with steel nails 13 according to the design position and spacing. Ensure that the length and number of steel nails 13 are sufficient to resist the shear force between the bottom formwork and the back ribs 7.

[0033] The bottom mold body 8, with the back rib 7 fixed in place, is hoisted or manually transported to the installation position. The back rib 7 is aligned with the corresponding groove 6 on the timber 3. The bottom mold body 8 is slowly lowered so that the back rib 7 begins to embed into the groove 6. As the back rib 7 continues to press down, when the side of the back rib 7 contacts the arc end face of the exposed arc-shaped clamp 11 of the sleeve 9, the downward pressure of the back rib 7 will act on the inclined surface of the arc-shaped clamp 11. Due to the effect of the inclined surface, the back rib 7 generates a component force on the arc-shaped clamp 11 pointing inward to the sleeve 9. This component force pushes the arc-shaped clamp 11 to overcome the elastic force of the spring 10 and slide and retract inward to the sleeve 9. At the same time, the spring 10 is compressed to store energy. When the back rib 7 continues to press down to the design elevation position (i.e., the bottom surface of the back rib 7 is in complete contact with the bottom surface of the groove 6, or reaches the preset installation height mark), the arc-shaped grooves 12 on both sides of the back rib 7 move to the position directly opposite the outlet of the sleeve 9.

[0034] At this point, the back rib 7 no longer exerts inclined pressure on the arc-shaped clamp 11, causing it to retract inward. The compressed spring 10 immediately releases its stored elastic force, pushing the arc-shaped clamp 11 to slide outward rapidly and reset along the axis of the sleeve 9. Under the action of the spring force, the arc-shaped head at the outer end of the arc-shaped clamp 11 precisely engages in the arc-shaped groove 12 on the side wall of the back rib 7. After the arc-shaped clamp 11 engages in the arc-shaped groove 12, under the continuous preload of the spring 10, the two form a dynamic elastic engagement. This engagement effectively restricts the displacement of the back rib 7 (together with the bottom mold body 8 on it) relative to the wooden block 3 in the vertical direction (Z direction, to prevent upward floating) and along the length direction of the back rib (Y direction, to prevent lateral slippage). At the same time, the structure of the back rib 7 embedded in the groove 6 itself restricts the horizontal displacement perpendicular to the length direction of the back rib (X direction). Thus, the bottom mold body 8 achieves precise positioning and reliable locking in three dimensions through this fixing structure.

[0035] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
