[0038] Refer to Figure 1 、 Figure 2 ,

[0039] The internal climbing jib tower crane is a tower crane used in construction, mainly for lifting materials in high-rise buildings and large-scale projects. It can self-climb as the height of the building increases during the construction process, so as to maintain its effective height during construction. The internal climbing jib tower crane is installed inside the building and fixed through the embedded parts 130 preset inside the building. Since the internal climbing jib tower crane exerts a relatively large pressure on the embedded parts 130, in order to ensure the stability and safety of the embedded parts 130, the present utility model provides a temporary reinforcement structure. This reinforcement structure is located inside the building and is specifically used to enhance the support for the embedded points.

[0040] Referring to Figure 1 、 2 , a temporary reinforcement structure includes: a first cross beam 110 and a second cross beam 120; an embedded part 130 is provided above the first cross beam 110 and the second cross beam 120; a first support 210 is connected between the first cross beam 110 and the second cross beam 120; a second support 220 is provided on the far side of the first cross beam 110 from the second cross beam 120 and on the far side of the second cross beam 120 from the first cross beam 110; the first support 210 and the second support 220 are located below the embedded part 130; one end of the second support 220 is connected to the first cross beam 110 or the second cross beam 120, and the other end is connected to the wall or beam of the building; there are inclined braces 310 arranged in an "eight" shape below the first cross beam 110 and the second cross beam 120; one end of the inclined brace 310 is connected to the first cross beam 110 or the second cross beam 120, and the other end is connected to the wall and / or beam of the building.

[0041] During use, square pipe is set on the embedded part 130 above the first cross beam 110 and the second cross beam 120. Two square pipes can be set, and both ends of which are respectively above the embedded part 130 above the first cross beam 110 and the second cross beam 120, and the square pipe is supported by the embedded part 130. Subsequently, these two square pipes are used to support the internal climbing jib tower crane. Obviously, such an installation method will generate a great pressure on the first cross beam 110 and the second cross beam 120. Therefore, by setting the first support 210, the second support 220 and the inclined brace 310, the first cross beam 110 and the second cross beam 120 are temporarily reinforced to improve the bearing capacity of the first cross beam 110 and the second cross beam 120, thereby ensuring the force safety and use safety of the internal climbing jib tower crane.

[0042] Specifically, referring to Figure 1, the first support 210 is arranged between the first cross beam 110 and the second cross beam 120, while the second support 220 is arranged outside the first cross beam 110 and the second cross beam 120. The first support 210 and the second support 220 act together to fix and limit the first cross beam 110 and the second cross beam 120, aiming to effectively eliminate the lateral stress that the internal climbing jib tower crane may generate on the first cross beam 110 or the second cross beam 120. This configuration can prevent the first cross beam 110 and the second cross beam 120 from deflecting when subjected to pressure, thereby enhancing the stability and safety of the overall structure. In addition, one end of the second cross beam 120 is fixedly connected to the first cross beam 110 or the second cross beam 120, and the other end is fixedly connected to the cross beam or wall within the building, depending on which position is closer.

[0043] Furthermore, referring to Figure 1 , 7 , the first support 210 is perpendicular to the first cross beam 110 and the second cross beam 120 respectively, the second support 220 is perpendicular to the first cross beam 110 or the second cross beam 120, and the second support 220 is located on the extension line of the first support 210. The first support 210 is arranged between the first cross beam 110 and the second cross beam 120 and is perpendicular to these two cross beams. The second support 220 is arranged outside the first cross beam 110 or the second cross beam 120 and is perpendicular to the cross beam, and at the same time is located on the extension line of the first support 210. Supports on the same extension line can provide support against lateral stress in a unified direction, which helps to evenly distribute the lateral force from the internal climbing jib tower crane, thereby reducing the lateral deformation and inclination of the cross beam. And ensuring that the first support 210 and the second support 220 are on the same extension line can prevent potential structural problems caused by uneven stress distribution. This symmetric and uniform support configuration can enhance the stability of the overall structure.

[0044] Furthermore, referring to Figure 6 , 7, first connecting plates 230 are provided at both ends of the first support 210 and the second support 220, and a plurality of first through holes 231 for bolts to pass through are provided on the connecting plates. Specifically, both the first support 210 and the second support 220 are I-beams. Using I-beams as the materials of the first support 210 and the second support 220, they have good load-bearing capacity and anti-deformation ability. The design of the I-beam structure provides a relatively large section modulus, which helps to bear the load exerted by the internal climbing jib tower crane and maintain the stability of the structure at the same time. First connecting plates 230 are provided at both ends of the first support 210 and the second support 220, which can increase the contact area between the first support 210 and the second support 220 with the first cross beam 110 or the second cross beam 120, and helps to evenly distribute the force at the support point to the connection part between the cross beam and the building body, thereby improving the overall stability of the structure. The setting of a plurality of first through holes 231 allows bolts to be installed in different combinations to meet different construction requirements. Specifically, a plurality of them are arranged along the circumferential direction of the first connecting plate 230, and then are fixedly connected to the first cross beam 110 or the second cross beam 120 through bolts. Among them, the bolts are preferably M20 chemical bolts.

[0045] In some embodiments, referring to Figure 2 , 5 , inclined braces 310 arranged in an "eight" shape are respectively provided below the first cross beam 110 and the second cross beam 120; one end of the inclined brace 310 is connected to the first cross beam 110 or the second cross beam 120, and the other end is connected to the wall and / or beam of the building body. It can be understood that the inclined braces 310 are used to support the lower parts of the first cross beam 110 and the second cross beam 120, and they are mainly used to provide vertical support, help share the load exerted by the internal climbing jib tower crane, reduce the deformation and inclination of the cross beam during the stress process, and ensure the stability of the structure and construction safety.

[0046] Furthermore, the inclined braces 310 are respectively located on both sides below the first cross beam 110 and the second cross beam 120. One end of the inclined brace 310 is connected to the first cross beam 110 or the second cross beam 120, and the other end is connected to the wall and beam of the building body. Here, the wall and beam are the building structures on the floors below the first cross beam 110 and the second cross beam 120. Part of the pressure of the internal climbing jib tower crane on the first cross beam 110 and the second cross beam 120 will be transmitted through the inclined braces 310. The wall and beam provide support in different directions, enabling the inclined braces 310 to exert forces on the cross beam in multiple directions, evenly distribute the load, reduce local stress concentration, thereby improving the overall stability of the structure and effectively preventing the inclination or deformation of the cross beam.

[0047] Furthermore, referring to Figures 3 - 5, both ends of the diagonal brace 310 are provided with second connecting plates 320. The middle body of the diagonal brace 310 is a rectangular steel pipe. A plurality of second through holes 321 for bolts to pass through are provided on the second connecting plates 320. It can be understood that, similar to the first connecting plate 230, the second connecting plate 320 provides a stable surface and increases the contact area for firmly connecting the end of the diagonal brace 310 to the wall and beam of the building body. The plurality of second through holes 321 allow the use of multiple bolts for fixation, enhancing the strength and stability of the connection, reducing potential safety hazards caused by connection point failure, and ensuring that the diagonal brace 310 will not loosen or fall off when bearing loads. Preferably, the bolt is an M20 chemical bolt.

[0048] Furthermore, the connection points of the diagonal brace 310 with the first cross beam 110 and the second cross beam 120 are located below the embedded part 130. Ensuring that the supporting force of the diagonal brace 310 is directly transmitted to the structural part of the building body can ensure that when the load is transmitted from the diagonal brace 310 to the building body, it can be effectively supported and distributed through the embedded part 130. This helps to optimize the load transmission path and reduce possible stress concentration problems.

[0049] Furthermore, referring to Figure 2 , the included angle a between the diagonal brace 310 and the first cross beam 110 and the second cross beam 120 is 45° - 60°. When the included angle between the diagonal brace 310 and the cross beam is larger, the moment generated by the diagonal brace 310 when bearing the load is greater. This will cause the diagonal brace 310 to exert a greater pressure on the lower beam. At the same time, the lateral component force borne by the wall is smaller, thereby reducing the pressure on the wall. In addition, by adjusting the included angle of the diagonal brace 310, the distribution of the load in the structure can be controlled to ensure that the main load is transmitted to the beam rather than the wall. This distribution method helps to optimize the stability of the structure and prevent the wall from deforming or being damaged due to excessive stress. Preferably, the included angle a between the diagonal brace 310 and the first cross beam 110 and the second cross beam 120 is 57°.

[0050] Through the mutual cooperation of the first support 210, the second support 220 and the diagonal brace 310, the first cross beam 110 and the second cross beam 120 are supported, significantly improving the support capacity and stability of these two cross beams when bearing the internal climbing jib tower crane. This structure effectively optimizes the transmission and distribution of the load, has good flexibility to adapt to different construction conditions, and while reducing construction costs and resource consumption, ensures the safety and economy of the construction.

[0051] The above is a specific description of the preferred embodiment of the present invention, but the present invention is not limited to the described embodiment. Those skilled in the art can also make various equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent deformations or substitutions are all included within the scope defined by the claims of this application.
