Description

Technical Field

[0001] The utility model relates to the technical field of concrete engineering, in particular to a supporting device for pouring cast-in-situ beams and corbel concrete. Background Art

[0002] In water conservancy and hydropower projects, pouring concrete for cast-in-place beams and corbel structures is a crucial step in the construction process. Since cast-in-place beams and corbel structures are located at a relatively high altitude from the ground, constructing a support system for the casting formwork is difficult. Currently, there are two main construction options. One is to directly use a floor-standing support frame, but building the scaffolding is labor-intensive and time-consuming, and the frame is prone to deformation, resulting in poor support effectiveness. The other is to embed I-beams in the upper layer of concrete in advance as a support system for the cast-in-place beam or corbel concrete formwork, and then remove the embedded I-beams after the casting is complete. However, this method is cumbersome, requiring each I-beam to be cut to the appropriate size before use. The I-beams then need to be removed after use, making them difficult to reuse. This results in significant material waste, high time and material costs, and low construction efficiency. Utility Model Content

A bracket is provided through the longitudinal support part of the support rod, and the transverse support part is threadedly connected to the embedded tube to realize the fixation of the support rod and facilitate loading and unloading. The stability of the support of the support rod is improved by the diagonal brace assembly.

[0004] A supporting device for pouring cast-in-place beams and corbel concrete comprises an embedded tube, a supporting sleeve and a diagonal brace assembly. The embedded tube is buried inside the concrete. The supporting sleeve is an L-shaped structure. A supporting rod is arranged inside the supporting sleeve. The supporting rod comprises a longitudinal supporting portion and a transverse supporting portion. One end of the longitudinal supporting portion extending out of the supporting sleeve is fixedly connected to a bracket for supporting the formwork. One end of the transverse supporting portion extending out of the supporting sleeve extends into the embedded tube and is threadedly connected to the embedded tube. The diagonal brace assembly is arranged at the bottom of the supporting sleeve.

[0005] A further technical solution is: a through L-shaped chamber is provided inside the supporting sleeve, and the adjacent ends of the longitudinal supporting portion and the transverse supporting portion are vertically connected.

[0006] A further technical solution is: the interior of the support sleeve is provided with a transverse chamber and a longitudinal chamber that are not connected to each other, the longitudinal support is threadedly connected to the inner wall of the longitudinal chamber, and both ends of the transverse support are provided with threads and are threadedly connected to the transverse chamber and the embedded tube respectively.

[0007] A further technical solution is that the diagonal bracing assembly includes a telescopic rod with an adjustable length arranged at the bottom of the supporting sleeve, and the bottom end of the telescopic rod is fixedly connected to a support plate.

[0008] A further technical solution is: the top end of the telescopic rod is fixedly connected with a mounting plate, and the mounting plate is fixedly connected to the bottom end of the supporting sleeve by bolts.

[0009] A further technical solution is: the telescopic rod includes an outer rod and an inner rod, and a plurality of limiting holes are opened on the outer rod and the inner rod at equal intervals along the length direction, and are threadedly connected to the corresponding limiting holes of the outer rod and the inner rod through a limiting screw.

[0010] A further technical solution is: the bracket is made of a steel plate with a thickness of 3 cm, and the support plate is made of a steel plate with a thickness of 1 cm.

[0011] Beneficial effects of the utility model:

[0012] The supporting device of the utility model is connected to the bracket through the longitudinal supporting part of the supporting rod, and the transverse supporting part is threadedly connected to the embedded tube, which is convenient for installation and disassembly. There is no need to cut after pouring, which avoids a lot of repetitive labor, reduces waste, can be reused, and reduces construction costs.

[0013] The support device of the utility model supports and fixes the support rod through the sleeve, and further strengthens the supporting effect through the diagonal support assembly, thereby ensuring the stability of the formwork during the pouring process, effectively ensuring the quality and safety of concrete pouring, and avoiding construction quality problems caused by unstable support.

[0023] Example 1:

[0024] A supporting device for pouring concrete of cast-in-place beams and corbels in Example 1, such as Figure 1-3 As shown, it includes an embedded tube 1, a support sleeve 2 and a diagonal bracing assembly 5. The embedded tube 1 is buried inside the concrete. The support sleeve 2 is an L-shaped structure. A supporting rod 3 is provided in the support sleeve 2. The supporting rod 3 includes a longitudinal supporting portion 32 and a transverse supporting portion 31. One end of the longitudinal supporting portion 32 extending out of the support sleeve 2 is fixedly connected to a bracket 4 for supporting the formwork. One end of the transverse supporting portion 31 extending out of the support sleeve 2 extends into the embedded tube 1 and is threadedly connected thereto.

[0025] The support sleeve 2 has an L-shaped chamber 21 extending therethrough. The support rod 3 is L-shaped, with a longitudinal support portion 32 perpendicularly connected to the adjacent ends of the transverse support portion 31. The junction between the longitudinal support portion 32 and the transverse support portion 31 fits within the L-shaped chamber 21. The support sleeve 2 is sleeved over the support rod 3, enhancing its strength and stability.

[0026] The diagonal brace assembly 5 is installed at the bottom of the support sleeve 2, providing a firm support against the poured concrete surface. The diagonal brace assembly 5 comprises an adjustable telescopic rod 51 at the bottom of the support sleeve 2, with a support plate 52 fixedly connected to the bottom end of the telescopic rod 51. The diagonal brace assembly 5 increases the contact area between the support device and the poured concrete, transferring part of the force applied to the support rod 3 to the support plate 52, further improving the strength and stability of the formwork support and ensuring the quality of the concrete pour.

[0027] The top of the telescopic rod 51 is fixedly connected to a mounting plate 53, which is fixedly connected to the bottom of the support sleeve 2 by bolts. The connection position of the bolts is not connected to the internal chamber of the support sleeve 2. The mounting plate 53 and the bolts are used to facilitate the installation and disassembly of the diagonal brace assembly 5.

[0028] The telescopic rod 51 includes an outer rod 511 and an inner rod 512 slidably connected to the outer rod 511. A plurality of limiting holes 513 are provided on the outer rod 511 and the inner rod 512 at equal intervals along the length direction, and are threadedly connected to the corresponding limiting holes 513 of the outer rod 511 and the inner rod 512 through limiting screws 514.

[0029] The bracket 4 is made of a steel plate with a thickness of 3 cm, and the size of the bracket 4 is 20×20 cm (length×width). The support plate 52 is made of a steel plate with a thickness of 1 cm, and the size of the support plate 52 is 10×10 cm (length×width).

[0030] The supporting device in this embodiment can be used for pouring the corbel concrete 6, such as Figure 2 As shown, during layout, the embedded tube 1 is pre-buried in the upper layer of concrete, and the transverse support portion 31 of the embedded part is then threaded into the embedded tube 1. The bracket 4 on the longitudinal support portion 32 of the embedded part supports the corbel casting template, and by adjusting the length of the telescopic rod 51 of the diagonal brace assembly 5, the support plate 52 is tightly pressed against the poured concrete surface to provide reinforced support for the support sleeve 2. After the construction of the corbel concrete 6 is completed, the support rod 3, support sleeve 2 and diagonal brace assembly 5 are removed, cleaned and put into the next use.

[0031] like Figure 3 As shown, the support device in this embodiment can also be used for pouring cast-in-place beam concrete 7. The support devices are symmetrically arranged on both sides of the bottom of the beam body. The arrangement and use methods are the same as described above and will not be repeated here.

[0032] Example 2:

[0033] A supporting device for pouring concrete of cast-in-place beams and corbels in Example 2, such as Figure 4 As shown, it includes an embedded tube 1, a support sleeve 2 and a diagonal brace assembly 5. The embedded tube 1 is buried inside the concrete. The support sleeve 2 is an L-shaped structure. A supporting rod 3 is provided in the support sleeve 2. The supporting rod 3 includes a longitudinal supporting portion 32 and a transverse supporting portion 31. One end of the longitudinal supporting portion 32 extending out of the support sleeve 2 is fixedly connected to a bracket 4 for supporting the formwork. One end of the transverse supporting portion 31 extending out of the support sleeve 2 extends into the embedded tube 1 and is threadedly connected thereto. The diagonal brace assembly 5 is provided at the bottom of the support sleeve 2.

[0034] The interior of the support sleeve 2 is respectively provided with a transverse chamber 221 and a longitudinal chamber 222. The transverse chamber 221 and the longitudinal chamber 222 are not communicated with each other. The longitudinal support portion 32 is threadedly connected to the inner wall of the longitudinal chamber 222. Both ends of the transverse support portion 31 are provided with threads and are respectively threadedly connected to the transverse chamber 221 and the embedded tube 1.

[0035] Example 2 is based on Example 1, and improves the support sleeve 2 and the support rod 3. During use, the extended horizontal length and vertical height can be adjusted by the threads on the horizontal support portion 31 and the longitudinal support portion 32, thereby facilitating the adjustment of the position of the bracket 4. When installing the casting formwork of corbels and cast-in-place beams of different shapes and sizes, adaptive adjustment is convenient. It has strong practicality and flexibility, can meet diverse construction needs, improve construction efficiency, and ensure stable support for the formwork.

[0036] The structure of the diagonal bracing assembly 5 of Example 2 is the same as that of Example 1 and will not be described again here.

[0037] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
