Description

Technical Field

[0001] This invention relates to a high formwork support device and construction method that are both adjustable inclination angle and width. Background Technology

[0002] In current construction projects, there is an increasing number of beams and slabs exceeding structural limits, as well as inclined slabs and beams designed to accommodate diverse building functions. Existing support systems typically use conventional screw-type U-shaped supports at the top of the uprights, with fixed dimensions. However, during actual installation, the limited width of the beams and the large size of the supports often prevent the calculated number from being placed under the beam, posing certain risks to the project. Furthermore, asymmetrical placement of the horizontal steel pipes within the supports frequently leads to eccentric loads, accelerating deformation and wear of the support plates and screws. When encountering inclined slabs and beams, the system cannot dynamically adapt to the structural angle, requiring inclined arrangement of uprights and supports, which inconveniences the implementation process, increases the workload of additional structural measures, reduces the efficiency of support frame construction, and has a certain economic impact.

Detailed Implementation

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] When constructing scaffolding under oversized beams, the number of uprights is often insufficient to support a large number of uprights according to calculations, especially with standard fixed-size support plates. Furthermore, due to the fixed size of the support plates, the steel pipes supporting the plates cannot be properly aligned, leading to eccentric loads on the uprights. When encountering haunches, inclined plates, or beams on the top slab, conventional methods require the addition of inclined scaffolding structures. These issues impact the safety and stability of the scaffolding construction, reduce construction efficiency, and have certain economic consequences.

Pallet fixing nuts 4 are respectively provided at both ends of the pallet adjusting screw 3 passing through the first side plate 1 and the second side plate 2. By adjusting the engagement position of the internal threads of the nuts 4 at both ends of the pallet adjusting screw 3 with the external threads of the pallet adjusting screw 3, the position of the second horizontal plate 20 within the gap between the first horizontal plate 18 and the first second horizontal plate 19 is adjusted, thereby increasing or decreasing the distance between the first side plate 1 and the second side plate 2.

[0054] In one embodiment of the high-support formwork top support device of the present invention with dual adjustment of tilt angle and width, a washer 5 is provided between one nut 4 and the corresponding first side plate; and another washer 5 is provided between the other nut 4 and the corresponding second side plate.

[0055] In one embodiment of the high formwork support device with dual adjustment of tilt angle and width of the present invention, at any position where the internal thread of the nut 4 at both ends of the support plate adjusting screw 3 engages with the external thread of the support plate adjusting screw 3, the support plate support rod 15 is always located at the central axis position between the first side plate 1 and the second side plate 2, so that the central axis of the horizontal steel pipe 16 and the central axis of the support plate support rod 15 are on a straight line.

[0056] In one embodiment of the high formwork support device with dual adjustment of tilt angle and width of the present invention, the angle adjustment device includes:

[0057] The first and second angle-adjusting ear plates 6 and 8 are symmetrically arranged at intervals on the lower part of the first horizontal plate 18, and the support rod 15 is arranged between the first and second angle-adjusting ear plates 6 and 8.

[0058] The first angle adjustment link 10 and the first second angle adjustment link 11 are respectively, wherein one end of the first angle adjustment link 10 is connected to the first angle adjustment ear plate 6 through the first angle adjustment ear plate bolt 7; and one end of the first second angle adjustment link 11 is connected to the first second angle adjustment ear plate 8 through the first second angle adjustment ear plate bolt 9.

[0059] The other end of the first angle adjustment link 10 and the other end of the first second angle adjustment link 11 are connected to the corresponding angle adjustment holes 17 on the support plate support rod 15 through the angle adjustment hole fixing bolts 14.

[0060] In one embodiment of the high formwork support device of the present invention, which has dual adjustment of tilt angle and width, the angle adjustment holes 17 on the support rod 15 of the support plate are arranged at intervals.

[0061] In one embodiment of the high-support formwork top support device with dual adjustment of tilt angle and width of the present invention, the first angle adjustment link 10 and the first and second angle adjustment links 11 are respectively adjustable length links, or, depending on the actual application and the position of the angle adjustment hole 17 of the support rod 15, the first angle adjustment link 10 and the first and second angle adjustment links 11 are respectively fixed length links corresponding to different modules.

[0062] The present invention also provides a construction method for the above-mentioned high formwork support device with dual adjustment of tilt angle and width, comprising:

[0063] Step S1: During the operation of the support frame under the over-limit beam, when the beam width cannot meet the existing conventional U-shaped support arrangement, a high-support top support device with dual adjustment of inclination angle and width is used to replace the traditional top support. After the horizontal steel pipe 16 between the first side plate 1 and the second side plate 2 is placed, the support plate adjusting screw 3 and the support plate fixing nut 4 are used to tighten the horizontal steel pipe 16 by supporting and contracting the first side plate 1 and the second side plate 2. At this time, the central axis of the horizontal steel pipe 16 is on the same straight line as the central axis of the support plate support rod 15, so as to realize the horizontal steel pipe 16 is symmetrically arranged with respect to the central axis of the support plate support rod 15. This reduces the space occupied by the first and second support plates in the limited width of the beam bottom and avoids the top support being eccentrically stressed. Among them, the first angle adjustment link 10 (adjustable length) and the first second angle adjustment link 11 (adjustable length) can be adjusted in length according to the distance between the first side plate 1 and the second side plate 2 of the support plate.

[0064] Step S2: When constructing inclined plates, beams, and support poles at haunch positions, the first and second angle-adjusting connecting rods 10 and 11, along with the angle-adjusting hole fixing bolts 14, are connected to the angle-adjusting holes 17 at different positions on the support rod 15. This is suitable for structural surfaces with different angles, eliminating the need for oblique structural arrangements and improving construction efficiency. The first and second angle-adjusting connecting rods 10 and 11 can be selected as adjustable-length connecting rods, or fixed-length connecting rods with different modules can be generated according to the actual application and the position of the angle-adjusting holes 17 on the support rod 15.

[0065] Here, after the horizontal steel pipe 16 is placed inside the first side plate 1 and the second side plate 2, the first side plate 1 and the second side plate 2 are retracted by the cooperation of the support plate fixing nut 4 and the support plate adjusting screw 3, so as to reduce the horizontal space occupied by the top support under the beam, which facilitates the arrangement of the top support under the beam. Since the first side plate 1 and the second side plate 2 symmetrically clamp the horizontal steel pipe 16, it can ensure that the top support is axially supported.

[0066] When constructing haunches, inclined plates, or beams, there is no need to tilt the uprights. The angle of the first support plate is changed by adjusting the angle adjustment holes 17 at different positions on the support rod 15 of the first and second angle adjustment rods 10 and 11 using the angle adjustment hole fixing bolts 14. This changes the angle of the second support plate, thus adapting to practical engineering applications. The first and second angle adjustment rods 10 and 11 can be adjustable-length connecting rod devices or rods with different modules can be generated based on the position of the angle adjustment holes in the support rod 15 for better applicability.

[0067] After the high-support formwork scaffold uprights are erected, the support plate support rod 15 of the high-support formwork top support device with dual adjustment of inclination angle and width can be installed together with the uprights. To adapt to different inclined floor slabs, this invention can select first and second angle-adjusting connecting rods 10 and 11 of different lengths, and connect them to the angle-adjusting holes 17 at different positions of the support plate support rod 15 through the angle-adjusting hole fixing bolts 14, forming a stable support system; to solve the problem of insufficient number of uprights due to the small spacing of the uprights under the over-limit beam, the distance between the first side plate 1 and the second side plate 2 is adjusted by the support plate fixing nut 4, minimizing the lateral space occupied by the support plate under the beam to meet the requirements of the upright arrangement.

[0068] In summary, this invention relates to the field of formwork support systems for building engineering, and is mainly applicable to formwork support devices for oversized beams, slabs, and inclined floor slabs and beams. Using this invention, the spatial layout of the formwork scaffolding under oversized beams and slabs can be optimized, and space utilization efficiency can be improved. Furthermore, the angle of the support plate can be dynamically adjusted according to the complex forms of beams and slabs caused by the diversity of actual inclined slabs, beams, and haunches. This device has a simple structure, requires no on-site assembly, and can be quickly adjusted and installed, exhibiting high applicability. It improves the stability of the scaffolding system under oversized beams and slabs; avoids accelerated deformation and wear of the support and uprights under the eccentric load of horizontal steel pipes; and improves the construction efficiency of inclined slabs, beams, and haunches.

[0069] This invention addresses the construction of scaffolding systems for oversized beams and slabs, and for inclined floor slabs and beams. It ensures sufficient support and uprights are provided under the oversized beams, reduces the eccentric load on the support, dynamically adjusts the inclination angle of the support plates to adapt to the structure, thus guaranteeing the safety and stability of the scaffolding support system, and improves the efficiency of scaffolding erection and its applicability to various working conditions.
