[0004] The support devices of the above-mentioned patents and prior arts are all lateral single-point supports. Even if the support position can be changed, when supporting a large area of ​​formwork, since the force points of the support devices are concentrated on the hinges of the support rods and the support plates, the formwork is subjected to the pressure of the unsolidified concrete on the opposite side of the support due to the high concentration of force points. This concentrated force situation causes the support devices to be prone to fatigue and damage under long-term or high-load work, which in turn causes the formwork to bend outward. This will not only affect the pouring quality of the concrete, resulting in problems such as uneven surface and reduced dimensional accuracy, but may also cause safety accidents, bringing huge risks to construction.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Reference Figure 1-3A formwork support device for construction engineering includes a base assembly 1 and a side panel assembly 2. The base assembly 1 is placed horizontally on the ground, and the side panel assembly 2 needs to be parallel to the formwork and laterally support the formwork. The ends of the base assembly 1 and the side panel assembly 2 are hinged, and the side panel assembly 2 realizes angle control by rotation, so as to match formworks with different installation angles. A retractable support member 3 is arranged between the base assembly 1 and the side panel assembly 2, so that the base assembly 1, the side panel assembly 2 and the support member 3 form a triangular structure. The base assembly 1 and the side panel assembly 2 are supported by the support member 3 to keep the structure stable. The angle adjustment of the side panel assembly 2 is realized by the extension and retraction of the support member 3.

[0029] The base assembly 1 includes two parallel channel steels 11, which are fixedly connected by a plurality of connecting rods 12. A fixed foot ring is provided on the side of the channel steel 11, and expansion screws and other fixing parts can be driven into the ground through the fixed foot ring to fix the base assembly 1, thereby improving the stability of the base assembly 1 and reducing the risk of lateral deviation when the device supports the formwork.

[0030] The side panel assembly 2 includes two mounting frames 21, and the two mounting frames 21 are in a parallel state. The two mounting frames 21 are fixedly connected by multiple cross bars 22 to form a mounting frame. The mounting frame is hinged to the end of the channel steel 11, and a multi-stage telescopic plate 23 connected to each other is slidably arranged on the mounting frame. The two adjacent telescopic plates 23 can be telescopically slid relative to each other along the length direction, and a locking structure is arranged between the telescopic plates 23. The multi-stage connected telescopic plates 23 have multiple supporting force points. The extension and shortening of the telescopic plates 23 can adjust the force distribution of the side panel assembly 2 when supporting the formwork, thereby improving the stability and reliability of the support device when supporting large-area formwork, avoiding deformation of the formwork caused by excessive concentration of force during formwork support, and thus improving the casting quality.

[0031] Reference Figure 1-3 The telescopic plate 23 includes two sliding rods 231 and a connecting shaft 232 fixed between the two sliding rods 231. The cross-sectional sizes of the sliding rods 231 of different telescopic plates 23 are different. The sliding rods 231 on the multi-stage connected telescopic plates 23 are sleeved together, and the cross-sectional area gradually decreases from the outside to the inside. A support plate 233 is rotatably connected to the connecting shaft 232. When the telescopic plate 23 rotates with the installation frame, the support plate 233 can be adaptively rotated after fitting the template, so that the support plate 233 is closely fitted with the surface of the template, effectively supporting the template, and ensuring the reliability and stability of the support device. The supporting surface of the support plate 233 is a rough surface, which increases the friction between the support plate 233 and the template and reduces the risk of side slipping when the support plate 233 is supported.

[0032] Reference Figure 1-3A slideway 24 adapted to the outermost sliding rod 231 is provided in the installation frame 21. The outermost sliding rod 231 is located in the slideway 24 and is slidably connected to the slideway 24. The sliding rod 231 can slide with the installation frame 21 to expand the adjustment range of the multi-stage connected telescopic plate 23, and when the device is idle, the telescopic plate 23 can be retracted into the installation frame 21 to reduce the space occupied by the device.

[0033] Reference Figure 1-3 The locking structure includes a latch 26 and a positioning hole 25 provided on the mounting frame 21 and the sliding rod 231. The latch 26 can pass through the mounting frame 21 and the sliding rod 231 through the positioning hole 25. After the telescopic plate 23 is telescoped, when the positioning holes 25 on the mounting frame 21 and the sliding rod 231 correspond, the latch 26 can be inserted into the positioning hole 25 to achieve fixation. Specifically, according to the sliding position of the mounting frame 21, it is necessary to ensure that at least one latch 26 is inserted into the corresponding positioning holes 25 on the two adjacent mounting frames 21 and the outer mounting frame 21 and the sliding rod 231 for locking.

[0034] Reference Figure 1-5 The support member 3 includes multiple groups of connecting sleeves 31 and telescopic rods 32. The connecting sleeves 31 and telescopic rods 32 of the same group are slidably sleeved and provided with a one-way limiting structure. When the side panel assembly 2 adjusts the angle and the telescopic plate 23 adjusts the height, the position compensation is performed by the telescopic rod 32 and the connecting sleeve 31 to keep the triangular structure stable. After the telescopic rod 32 and the connecting sleeve 31 are extended and retracted, the one-way limiting structure keeps the positions of the connecting sleeve 31 and the telescopic rod 32 unchanged. Under the action of the one-way limiting structure, the telescopic rod 32 can be freely extended and the retraction direction is limited. Position, so that the support member 3 has a sufficient supporting effect, and multiple groups of connecting sleeves 31 and telescopic rods 32 are respectively connected to different connecting rods 12 and connecting shafts 232, wherein the connecting sleeve 31 is rotatably connected to the connecting rod 12, and the telescopic rod 32 is rotatably connected to the connecting shaft 232. Multiple groups of connecting sleeves 31 and telescopic rods 32 support different telescopic plates 23 and provide multi-point supporting force. When the telescopic plate 23 changes position, the corresponding supporting point should also change. When supporting a large area template, the force points can be dispersed to avoid deformation of the template caused by excessive concentration of support force points.

[0035] Reference Figure 1-5The one-way limiting structure includes a locking sleeve 33 slidably arranged on the connecting sleeve 31 near one end of the telescopic rod 32. The telescopic rod 32 passes through the locking sleeve 33. A return spring 34 is arranged between the locking sleeve 33 and the connecting sleeve 31. There is damping between the telescopic rod 32 and the locking sleeve 33. When the telescopic rod 32 is extended outward, the locking sleeve 33 will be driven to move outward, but under the pulling force of the return spring 34, the elastic force of the return spring 34 is greater than the friction resistance between the telescopic rod 32 and the locking sleeve 33, and the telescopic rod 32 and the locking sleeve 33 will slide. The overlapping part of the locking sleeve 33 and the connecting sleeve 31 is a conical and elastic deformation part 331. The side wall of the deformation part 331 is axially provided with a plurality of openings 332. When the telescopic rod 32 is retracted into the connecting sleeve 31, the locking sleeve 33 is driven to move into the inside of the connecting sleeve 31, so that the deformation part 331 is squeezed against the inner wall of the connecting sleeve 31, so that the deformation When the locking cam 33 is in the state of being stretched, the locking cam 33 is in the state of being contracted and pushed inwardly, so that the locking cam 33 is in the state of being stretched and pushed inwardly, so that the locking cam 33 is in the state of being stretched and pushed inwardly, so that the locking cam 33 is in the state of being stretched and pushed inwardly, so that the locking cam 33 is in the state of being stretched and pushed inwardly, so that the locking cam 33 is in the state of being stretched and pushed inwardly, so that the locking cam 33 is in the state of being stretched and pushed inwardly, so that the locking cam 33 is in the state of being stretched and pushed inwardly,

[0036] Working principle:

[0037] When in use, the position of the telescopic plate 23 is adjusted according to the size of the template to be supported. The initial state of the telescopic plate 23 is the overlapping and contracted state. Adjusting the multi-stage telescopic plate 23 to extend outward will pull the telescopic rod 32 outward, which will drive the locking sleeve 33 to move outward and stretch the reset spring 34 until the elastic force of the reset spring 34 is greater than the friction resistance between the telescopic rod 32 and the locking sleeve 33, the telescopic rod 32 and the locking sleeve 33 slide, and the movement is not restricted. The template support device is moved to one side of the template, the channel steel 11 is fixed to the ground, and the side plate assembly 2 is rotated to make the support plate 23 3 is fitted with the template for support. When the side panel assembly 2 rotates toward one side of the template, the telescopic rod 32 will also be stretched to adapt to the angle adjustment of the side panel assembly 2. When the support plate 233 supports the template, the pressure of the template acts on the support plate 233, exerting pressure on the telescopic rod 32, so that the telescopic rod 32 tends to shrink. When the telescopic rod 32 shrinks into the connecting sleeve 31, it drives the locking sleeve 33 to move into the inside of the connecting sleeve 31, so that the deformation part 331 is squeezed toward the inner wall of the connecting sleeve 31, so that the deformation part 331 is gathered toward the center and pressed against the outer wall of the telescopic rod 32, so as to achieve locking and provide stable support.
