Description

Technical Field

[0001] This utility model relates to the field of support device technology, specifically a support device for installing concrete components. Background Technology

[0002] Support devices for concrete component installation are crucial equipment in building construction to ensure accurate positioning and structural stability of components. They are used for the temporary fixing and positioning of precast wall panels, columns, beams, and other components, ensuring that the components do not shift or tilt during installation. These support devices typically employ adjustable telescopic structures and are equipped with threaded adjustment mechanisms for quick adjustment of the support height.

[0003] Under current technology, the support equipment used for installing concrete components mainly relies on threaded structures for length adjustment. When the adjustment range is small, this threaded adjustment method is sufficient and convenient. However, in scenarios involving long-distance adjustments, such as adjusting the device length by tens of centimeters at a time, relying solely on threaded adjustment reveals serious drawbacks—not only is the adjustment efficiency extremely low, but the operation process is also cumbersome and complex, causing significant inconvenience to construction workers. Therefore, to address this long-standing industry problem, there is an urgent need to develop a new type of support device for installing concrete components to fundamentally improve existing adjustment methods and enhance construction efficiency and quality. Utility Model Content

[0004] The purpose of this utility model is to provide a support device for installing concrete components, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a support device for installing concrete components, comprising a first support rod, a second support rod movably sleeved on the outer surface of the lower end of the first support rod, a third support rod disposed at the lower end of the second support rod, a coarse adjustment mechanism disposed between the first support rod and the second support rod, and a fine adjustment mechanism disposed between the second support rod and the third support rod. The coarse adjustment mechanism comprises a fixing ring, a connecting piece, a claw, a groove, and a compression sleeve. A fixing ring is fixedly disposed on the outer surface of the second support rod, a connecting piece is fixedly disposed on the outer surface of the fixing ring, a claw is fixedly disposed at one end of the connecting piece, a plurality of grooves are evenly distributed on the outer surface of the first support rod, and a compression sleeve is movably screwed onto the outer surface of the fixing ring.

[0006] Preferably, the connecting piece is made of an elastic metal material. The elastic metal material can have sufficient structural strength and can automatically use its own elasticity to drive the jaws to open outwards when the jaws are not squeezed by the compression sleeve, so that they can disengage from the jaw groove. At this time, the first support rod can move inside the second support rod, thereby quickly adjusting the overall length of the device.

[0007] Preferably, the outer surface of the extrusion sleeve is provided with anti-slip protrusions. The anti-slip protrusions can increase the friction of the outer surface of the extrusion sleeve, thereby making it easier to rotate the extrusion sleeve to prevent slippage.

[0008] Preferably, the fine adjustment mechanism includes an annular groove and a threaded sleeve. The annular groove is fixedly provided on the outer surface of the third support rod, and the threaded sleeve is movably provided on the outer surface of the annular groove. The threaded sleeve is screwed to the second support rod through a thread. By rotating the threaded sleeve, the distance between the second support rod and the third support rod can be adjusted under the action of the thread. The thread adjustment of the threaded sleeve is a fine adjustment, which has low adjustment efficiency but more precise length adjustment.

[0009] Preferably, a handle is fixedly provided on the outer surface of the threaded sleeve, which allows the threaded sleeve to be rotated easily.

[0010] Preferably, the ends of the first and third support rods away from the second support rod are each fixedly provided with mounting plates. The four corners of the outer surface of the mounting plate are provided with mounting holes. The first, second, and third support rods can be easily fixed between the precast wall and the floor slab through the mounting plate and mounting holes, thus providing temporary support for the precast wall.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model is equipped with coarse adjustment and fine adjustment parts, which can meet the adjustment efficiency requirements of small-range precise adjustment while also meeting the adjustment requirements of large-range coarse adjustment, thus improving the use effect of this device.

[0013] 2. The entire device is easy to adjust when in use, without the need for additional tools or pins. For coarse adjustment, simply rotate the extrusion sleeve; for fine adjustment, simply rotate the threaded sleeve. This makes it convenient to use and easy to promote. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a support device for installing concrete components, including a first support rod 1, a second support rod 2 movably sleeved on the lower outer surface of the first support rod 1, a third support rod 3 provided at the lower end of the second support rod 2, a coarse adjustment mechanism provided between the first support rod 1 and the second support rod 2, and a fine adjustment mechanism provided between the second support rod 2 and the third support rod 3. The coarse adjustment mechanism includes a fixing ring 4, a connecting piece 5, a claw 6, a groove 7, and a compression sleeve 8. The fixing ring 4 is fixedly provided on the outer surface of the second support rod 2, the connecting piece 5 is fixedly provided on the outer surface of the fixing ring 4, a claw 6 is fixedly provided at one end of the connecting piece 5, a plurality of grooves 7 are evenly opened on the outer surface of the first support rod 1, and the compression sleeve 8 is movably screwed onto the outer surface of the fixing ring 4.

[0021] The connecting piece 5 is made of elastic metal material. While having sufficient structural strength, the elastic metal material can automatically use its own elasticity to drive the claw 6 to open to all sides when the claw 6 is not squeezed by the compression sleeve 8, so that it can be separated from the slot 7. At this time, the first support rod 1 can move inside the second support rod 2, so that the overall length of the device can be quickly adjusted.

[0022] The outer surface of the extrusion sleeve 8 is provided with anti-slip protrusions, which can increase the friction of the outer surface of the extrusion sleeve 8, thereby making it easier to rotate the extrusion sleeve 8 to prevent slippage.

[0023] The fine adjustment mechanism includes an annular groove 9 and a threaded sleeve 10. The annular groove 9 is fixedly provided on the outer surface of the third support rod 3, and the threaded sleeve 10 is movably provided on the outer surface of the annular groove 9. The threaded sleeve 10 is screwed to the second support rod 2 through a thread. By rotating the threaded sleeve 10, the distance between the second support rod 2 and the third support rod 3 can be adjusted under the action of the thread. The thread adjustment of the threaded sleeve 10 is a fine adjustment, which has low adjustment efficiency but more precise length adjustment.

[0024] A handle 11 is fixedly provided on the outer surface of the threaded sleeve 10, and the threaded sleeve 10 can be easily rotated by the handle 11.

[0025] The first support rod 1 and the third support rod 3 are each fixedly provided with an installation plate 12 at the end away from the second support rod 2. The four corners of the outer surface of the installation plate 12 are each provided with an installation hole 13. The first support rod 1, the second support rod 2 and the third support rod 3 can be easily fixed between the precast wall and the floor slab through the installation plate 12 and the installation hole 13, so as to temporarily support the precast wall.

[0026] Working principle: When using this device, the first support rod 1, the second support rod 2 and the third support rod 3 can be easily fixed between the precast wall and the floor slab through the mounting plate 12 and the mounting hole 13, so as to temporarily support the precast wall.

[0027] This device can also be adjusted in length as needed. The adjustment method can be selected according to the adjustment requirements. If a longer adjustment length is required, the compression sleeve 8 can be rotated by thread to stop it from pressing the outer surface of the jaw 6. Under the elastic action of the connecting piece 5, the jaw 6 can then move out of the slot 7, allowing the first support rod 1 to move inside the second support rod 2, thus quickly adjusting the overall length of the device. When the desired length is reached, the compression sleeve 8 is tightened again to allow the jaw 6 to engage with the nearest slot 7, thus fixing the lengths of the first support rod 1 and the second support rod 2. Fine-tuning can then be performed. During fine-tuning, rotating the threaded sleeve 10 adjusts the distance between the second support rod 2 and the third support rod 3. The threaded adjustment of the threaded sleeve 10 is a fine adjustment, providing more precise length adjustment. Thus, this device has both coarse and fine adjustment sections, satisfying both precise small-range adjustments and large-range coarse adjustment efficiency requirements, thereby improving the device's performance.

[0028] Furthermore, this device is easy to adjust during use, without the need for additional tools or pins. For coarse adjustments, simply rotate the extrusion sleeve 8; for fine adjustments, simply rotate the threaded sleeve 10. This ease of use facilitates its widespread adoption.
