Description

Technical Field

[0001] The utility model belongs to the technical field of tower crane fixing, and particularly relates to a tower crane embedded part device. Background Technique

[0002] During the construction process, especially when the construction height is relatively high, it is necessary to install a tower crane at the construction position to transport the materials for high-altitude construction through the tower crane. During the construction process of the tower crane, due to the very high height of the tower crane, in order to ensure the construction safety, the tower crane often needs to be fixed in a very stable manner. Specifically, according to the height of the tower crane, tower crane attaching arms are installed at different height positions on the tower crane, and the tower crane attaching arms are attached and installed on the wall, such as the shear wall.

[0003] Therefore, during the construction process, it is necessary to pre-install the embedded parts for attaching and installing the tower crane on the wall. At present, the main structure of the embedded parts adapted to the tower crane attaching arms includes an embedded plate and several embedded rods welded on the embedded plate. During the working process, the tower crane attaching wall is installed on the ear plate on the embedded plate and is pinned to fix the tower crane.

[0004] However, it is found in actual construction that when the construction height of the tower crane is relatively large, the overall load of the tower crane is relatively large, and during the construction process, the materials lifted by the tower crane are relatively heavy, resulting in an increase in the load of the tower crane, while the stability of the embedded parts with a conventional structure is insufficient. Specifically, the load of the tower crane is borne on the embedded parts. When the load is relatively large, the stability requirements for the embedded parts are very high. Once the stability between the embedded parts and the concrete structure is not firm, the tower crane attaching wall will be loosened at least, and at worst, the embedded parts cannot withstand the high-pressure load and will loosen and fall off from the wall. Once the tower crane attaching wall is loosened, the stability of the entire tower crane will be greatly reduced, and major construction safety accidents are likely to occur.

[0005] Therefore, during the construction process of the tower crane, it is necessary to jack up and maintain the embedded parts. However, for the embedded parts with a large working load, in the actual construction process, not only the stability duration is short, but also once they are loosened, subsequent maintenance and replacement are very cumbersome. Therefore, for the case of a relatively large erection height and a large weight of the lifted materials during the working process, the ordinary embedded parts for attachment obviously cannot meet the construction requirements in terms of stability and safety. Summary of the Utility Model

[0006] Based on the above background, the purpose of the utility model is to provide a tower crane embedded part device.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0019] Preferably, a main pull hook with a hooked setting is integrally formed at the front end of the transverse tension bar;

[0021] Preferably, both the outer hook bar and the inner hook bar include vertical reinforcing bar parts welded to the hoop bar, and a hooked reinforcing bar part with a hooked setting is integrally formed on the vertical reinforcing bar part.

[0022] Preferably, the hooked reinforcing bar parts on the outer hook bar and the inner hook bar have different hooked directions.

[0023] Preferably, a plurality of tie bars are welded on the wall attachment plate, and a hook pulling portion provided with an inwardly bent hook is integrally formed at the inner end of the tie bar plate.

[0038] Embodiment 1

[0039] As Figures 1-4 shown, a tower crane embedded part device includes a tower crane arm attached wall embedded mechanism. The tower crane arm attached wall embedded mechanism includes an attached wall plate 1 (the shape of the attached wall plate 1 is circular and it is made of steel plate material). An ear plate 2 is fixedly connected to the outer side wall of the attached wall plate 1 (specifically, the ear plate 2 includes ear plate 2 parts arranged at intervals up and down, and a connecting plate part is integrally formed between the ear plate 2 parts. The connecting plate part is welded to the attached wall plate 1, and the attached arm of the tower crane is fixed on the ear hole 21 on the ear plate 2).

[0040] In order to improve the stability between the embedded mechanism of the tower crane arm attachment wall and the wall, a pre-embedded hook cage assembly is fixedly connected to the inner side wall of the above-mentioned attachment wall panel 1. Specifically, the cage steel bar structure design of the pre-embedded hook cage assembly is adopted to ensure that after pouring, the cage steel bar structure can fully pull and fix the concrete.

[0041] The specific structure of the pre-embedded hook cage assembly is as follows:

[0042] The pre-embedded hook cage assembly includes a number of transverse tension bars 41 fixedly connected to the attachment wall panel 1 (the transverse tension bars 41 are welded to the edge part of the front side wall of the attachment wall panel 1, and their length is 30 - 60 cm. In this way, during the construction process, a horizontal tensile force is formed between the transverse tension bars 41 and the wall, so that when the tower crane attachment arm is pulled, a large anti-pulling and loosening ability can be maintained).

[0043] At the same time, in order to improve the anti-pulling and loosening effect of the transverse tension bars 41, a main pulling hook 411 with a hooked shape is integrally formed at the front end of the above-mentioned transverse tension bars 41 (the function of the main pulling hook 411 is to anchor and fix the entire device from the end position).

[0044] At the same time, in order to improve the stability of the pre-embedded device in a segmented anchoring manner, a number of pulling hooks 412 for pulling are fixedly connected to the above-mentioned transverse tension bars 41, and the pulling hooks 412 are welded to the transverse tension bars 41. And the pulling hooks 412 are arranged at intervals on the transverse tension bars 41. During the working process, the pulling hooks 412 embedded in the concrete structure form a hook pulling force through the pulling hooks 412, thereby further increasing the anti-pulling and loosening ability of the pre-embedded device. And due to the segmented design of the pulling hooks 412, multiple segmented hook pulling and anchoring points are formed on the entire device, thereby greatly improving the anti-pulling and loosening ability of the entire device.

[0045] Embodiment 2

[0046] As Figures 1-4 shown, on the basis of the structure of Embodiment 1 in this embodiment, in order to further improve the anti-pulling and loosening ability of the pre-embedded device, a number of spaced ring hoop bars 5 are fixedly connected between the above-mentioned transverse tension bars 41; the transverse tension bars 41 are fixedly connected to the inner side wall of the ring hoop bars 5; a number of double hook members for circumferential pulling are fixedly connected to the ring hoop bars 5, and the double hook members include outer hook bars 51 fixedly connected to the outer side wall of the ring hoop bars 5 and inner hook bars 52 fixedly connected to the inner side wall of the ring hoop bars 5.

[0047] Specifically, a cage anchor structure is formed by the hoop rod 5 and the transverse tension bar 41, and the cage anchor structure greatly increases its stability with the concrete. Moreover, different from the pulling force direction of the above-mentioned hook 412, the double-hook member on the hoop rod 5 is fixed in a circumferential manner. Specifically, the outer hook bar 51 and the inner hook bar 52 of the double-hook member form multiple layers of pulling forces in a circumferential manner. This anchoring method realizes the anchoring and fixing force on the embedded device from all directions, thereby further improving its embedded stability.

[0048] Specifically, both the above-mentioned outer hook bar 51 and inner hook bar 52 include vertical reinforcing bar parts welded to the hoop rod 5, and the vertical reinforcing bar parts are integrally formed with hook-shaped reinforcing bar parts with a hook setting. The hook directions of the hook-shaped reinforcing bar parts on the outer hook bar 51 and the inner hook bar 52 are different. The purpose of using different hook directions is to ensure different pulling and fixing force directions and realize the pulling and fixing from different directions.

[0049] Embodiment 3

[0050] As Figures 1-4 shown, on the basis of the structure of Embodiment 1 in this embodiment, a plurality of connecting rib plates 11 are respectively welded to the top and bottom of the above-mentioned connecting plate part, and the connecting rib plates 11 are welded to the attached wall panel 1.

[0051] Specifically, the longitudinal cross-sectional shape of the connecting rib plate 11 is a right triangle, and the right-angled surface of the connecting rib plate is welded to the attached wall panel 1 and the connecting plate part.

[0052] Meanwhile, in order to further improve the stability of the attached wall panel 1, a plurality of tension rib plates 3 (the tension rib plates 3 are steel plates) are welded to the above-mentioned attached wall panel 1, and the inner end of the tension rib plate 3 is integrally formed with a hook pulling part with an inner hook setting. During the working process, when the embedded part is installed, the tension rib plate 3 follows the embedded wall. Because the tension rib plate 3 is close to the wall surface position, it is reinforced from the outer layer position.

[0053] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the essence of the present invention should also fall within the protection scope of the present invention.
