Description

Technical Field

[0001] This utility model belongs to the technical field of cantilever formwork fixing equipment, and relates to a cantilever formwork fixing device that facilitates hoisting on sloping surfaces. Background Technology

[0002] In concrete construction, to save construction costs and accelerate construction progress, large-volume concrete formwork typically employs cantilever steel formwork, which can be hoisted and expedite the erection of formwork at concrete pouring sections. For roller-compacted concrete cofferdams in construction projects, where the upstream design inclination angle is greater than or equal to 30 degrees and less than 90 degrees, using assembled steel formwork would restrict construction progress and costs. Therefore, a planar cantilever steel formwork construction process was adopted. Because the cofferdam's design inclination angle is greater than or equal to 30 degrees and less than 90 degrees, the process of hoisting and installing the planar cantilever steel formwork differs from that on a vertical concrete surface. Under the weight of the steel formwork, its lower support components are in close contact with the poured concrete surface. During hoisting, the contact points between the support components and the concrete slope are in a rigid sliding contact. Dragging during hoisting causes wear and tear on the concrete slope and support components, leaving scratches on the concrete slope and affecting the service life of the cantilever formwork support components.

[0003] In summary, existing technologies have the problem of damaging the concrete slope surface during the hoisting and dragging of cantilever formwork. Utility Model Content

[0022] Cantilever formwork fixing devices that facilitate hoisting on slopes, such as Figure 1 As shown, the system includes a cantilever formwork 2. Several main back ribs 3, each with a square rod-like structure, are attached to one side of the cantilever formwork 2. One end of each main back rib 3 has a perforated lifting lug 1, and the other end has a walking platform base plate 7.

Several diagonal braces 4 are provided between the main back rib 3 and the main back rib base 6. Several bolt holes are provided on the main back rib 3 and the main back rib base 6 respectively. One end of the diagonal brace 4 is hinged to the main back rib 3 through the bolt hole in the middle of the main back rib 3, and the other end is fixed to the diagonal brace base 5. The diagonal brace base 5 is hinged to the main back rib base 6 through the bolt hole in the middle of the main back rib base 6.

[0025] like Figure 3As shown, the main beam inclined triangular frame 8 includes a first square rod, one end of which is fixedly connected to the end of a second square rod, and the other end of which is fixedly connected to the end of an inclined rod. The other end of the inclined rod is fixedly connected to the other end of the second square rod, and the angle between the first and second square rods is a right angle. The first square rod is fitted to the bottom plate 7 of the walking platform, and a bolt hole is provided at one end of the first square rod, which is matched with a pre-embedded screw 13.

[0026] like Figure 4 As shown, the roller device 9 includes a perforated lug seat, which is located on the side wall of the end of the second square rod away from the first square rod. A roller 11 is installed inside the perforated lug seat. The perforated lug seat and the roller 11 are connected by a roller shaft 12.

The second square bar is arranged in parallel with the wall surface of the concrete wall 10.

[0028] In this utility model, the cantilever formwork structure mainly consists of cantilever formwork 2 and main back ribs 3. Each cantilever formwork 2 is fixedly connected to two main back ribs 3 by high-strength bolts. The top of each main back rib 3 has perforated lifting lugs 1 for easy hoisting of the entire cantilever formwork 2 assembly. The middle section has evenly spaced bolt connection holes to allow adjustment of the installation angle of the cantilever formwork 2 according to the slope of the concrete wall.

The main back ribs 3 are connected to the walking platform base plate 7 by diagonal braces 4, with each cantilever formwork 2 connected by two diagonal braces 4.

[0029] In this utility model, the walking platform base plate 7 is provided with a main back rib base 6 and a diagonal brace base 5, which are connected to the main back rib 3 and the diagonal brace 4 respectively. The top part of the main beam inclined triangular frame 8 is provided with a screw connection hole, which is connected to the pre-embedded screw 13 on the concrete wall 10. The legs of the main beam inclined triangular frame 8 are provided with a roller device 9, which is connected to the legs of the main beam inclined triangular frame 8 through rollers 11 and roller shafts 12, so as to facilitate rolling contact between the legs of the triangular frame and the poured concrete wall surface when the legs are hoisted and climbed. The poured concrete wall 10 is provided with a pre-embedded screw 13, which is connected to the screw holes on the main back rib base 6 and the main beam inclined triangular frame 8, mainly to support the load-bearing function of the cantilever formwork device.

[0030] The process of installing the roller device for cantilever formwork on a slope is as follows: After the preliminary work is completed, the main beam inclined triangular frame 8 can be installed separately, which can effectively simplify the installation process. After adjusting the position of the main beam inclined triangular frame 8, the first step is to align the center hole of the roller 11 with the bolt hole on the leg of the main beam inclined triangular frame 8; the second step is to insert the roller shaft 12 into the center shaft of the roller 11 and check the rolling of the roller 11 to ensure that the roller 11 is in a good rotating state; the third step is to install and tighten the positioning limiting bolts at both ends of the center shaft of the roller 11; the fourth step is to check the rolling state of the roller 11 again after tightening the positioning limiting bolts to confirm its rotation state. After installing the roller device 9 at the leg of the main beam inclined triangular frame 8, the overall hoisting procedure of the cantilever formwork on the slope is carried out in accordance with the cantilever formwork installation specifications.

[0031] When used in the construction of sloping concrete pouring in a certain engineering project, this utility model can effectively protect the integrity of the concrete wall during construction without affecting the tight connection between the device and the wall. This utility model is simple to modify, easy to operate, and safe and reliable, and can effectively improve the efficiency of sloping concrete construction.

[0032] In the construction process of cantilever formwork erection on concrete surfaces with a large slope, this utility model ensures that the cantilever formwork does not drag or damage the already poured concrete surface during the lifting and installation process. At the same time, it realizes rolling as it rises during the lifting process, reducing frictional resistance and facilitating the formwork erection process and operational safety. The improved and added roller device has strong operability and practicality without damaging the original structural characteristics and stress state of the cantilever formwork.

[0033] This invention adds a set of rollers to the contact area between the concrete wall 10 and the main beam inclined triangular frame 8. This ensures that the main beam inclined triangular frame 8 does not make hard contact with the poured concrete wall surface when it is dragged and lifted. This solves the problem of unevenness when the cantilever formwork fixing device is in close contact with the concrete wall 10. It not only ensures the stability of the connection between the main beam inclined triangular frame 8 and the poured concrete wall 10 during concrete pouring, but also ensures the smoothness of the cantilever formwork device when it is hoisted, dragged and lifted on the poured concrete wall 10. This can effectively improve the efficiency of sloping concrete pouring.
