[0017] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0018] 1. The construction of back jacking support is omitted: the side wall of the opening of the dark beam connecting the top plate large surface surrounds the opening. The end of the dark beam is fixedly connected with the main beam. Since the dark beam is fixedly connected with the main beam and is fixed in the top plate large surface by pouring concrete, the main beam and the dark beam share the stress, thereby enhancing the structural stability of the opening position of the top plate large surface. Further, the back jacking support is not needed, thereby reducing the back jacking construction, saving the back jacking cost, avoiding the occupation of a part of the basement space by the support and affecting the construction of the basement.

[0019] 2. The top plate is kept neat: since the dark beam covers the opening edge of the top plate large surface, the steel bars in the interior of the top plate large surface are not exposed at the opening, so that the opening vicinity is kept neat, which is beneficial to the on-site safety and civilized construction inspection and the evaluation of the standardized construction site.

[0025] EXAMPLE

[0026] Example 1 provides a tower crane marker section top-penetrating structure, as shown in Figure 1 The specific structure is described as follows.

[0027] The tower crane marker section top-penetrating structure of the utility model example mainly includes three parts of the large face of roof 1, the main beam 3 and the concealed beam 4. In combination with Figure 1 The large face of roof 1 is the roof above the basement, generally using concrete pouring, sometimes also installing reinforcing steel bars before concrete pouring in order to increase the strength.

[0028] Further, in combination with Figure 1 As shown in the drawing, the opening 101 is square in shape, and other examples can also be other shapes, for example, pentagon, etc. When the tower crane is installed, the tower crane marker section 2 penetrates through the opening 101. In order to avoid the influence of the vibration of the tower crane marker section 2 on the large face of roof 1 during work, the distance between the side wall of the opening 101 and the tower crane marker section 2 is greater than 20 cm, and the preferred distance is 25 cm.

[0029] In some embodiments of the present embodiment, the main beam 3 is installed around the outer side of the roof slab 1, and the four corners of the main beam 3 are supported by reinforced concrete columns.

[0030] Further, as shown in Figure 1 , the four hidden beams 4 include two longitudinal and two transverse beams arranged in a crisscross manner, and the ends of the hidden beams 4 are fixedly connected with the main beam 3. The four hidden beams 4 are also installed on the side walls of the opening 101. The hidden beams 4 and the main beam 3 cooperate to increase the strength of the position of the opening 101, so that the back support at the opening 101 is not needed.

[0031] In some embodiments of the present embodiment, in combination with Figure 1 , the hidden beam 4 includes an upper part and a lower part. Two upper parts and three lower parts are arranged and installed along the roof slab 1, and after the concrete is poured, the hidden beam 4 is located inside the roof slab 1, which can increase the strength and does not affect the appearance.

[0032] Further, in combination with Figure 1 , a water stop steel plate 5 is installed on the side wall of the opening 101, one side of the water stop steel plate 5 is embedded into the inside of the roof slab 1, and the other side of the water stop steel plate 5 extends and is located inside the hidden beam 4. And the water stop steel plate 5 faces the water side, which plays a good waterproof role.

[0033] When the tower crane marker section 2 is removed, the steel bars are directly placed on the hidden beam 4, the steel bars cover the opening 101, and then the concrete is poured to close the opening 101. Due to the cooperation of the main beam 3 and the hidden beam 4, the force is large, and the back support is not needed, which saves the cost of back support.

[0034] The working principle of the tower crane marker section top structure of the present application is as follows:

[0035] The hidden beam 4 connects the side wall of the opening 101 of the roof slab 1, and the hidden beam 4 surrounds the opening 101 to form a circle. The end of the hidden beam 4 is fixedly connected with the main beam 3. Since the hidden beam 4 and the main beam 3 are fixedly connected, and the hidden beam 4 is fixedly connected in the roof slab 1 by pouring concrete, the main beam 3 and the hidden beam 4 share the stress, which enhances the structural stability of the position of the opening 101 of the roof slab 1. Further, the back support is not needed, which reduces the back construction and saves the back cost, and also avoids that the support occupies a part of the basement space and affects the construction of the basement. Due to the arrangement of the hidden beam 4, the hidden beam 4 covers the edge of the opening 101 of the roof slab 1, avoids that the steel bars inside the roof slab 1 are exposed at the opening 101, and keeps the vicinity of the opening 101 neat, which is beneficial to the on-site safety and civilized construction inspection and the evaluation of the standardized construction site.

[0036] The utility model provides a tower crane mark section 2 wears top structure, it includes roof large surface 1, the outside of roof large surface 1 is provided with main beam 3, the center of roof large surface 1 is provided with the opening 101 for tower crane mark section 2 to pass, and roof large surface 1 is provided with the hidden beam 4 of being connected with main beam 3, and the side wall of hidden beam 4 connects opening 101. The side wall of opening 101 is provided with the water stop steel sheet 5 towards the water face. Opening 101 is square. Four hidden beams 4 crisscross. Hidden beam 4 includes upper part muscle and lower part muscle. The spacing of hidden beam 4 from tower crane mark section 2 is not less than 20 centimeters. Roof large surface 1 is provided with the guardrail of enclosing opening 101. Hidden beam 4 after tower crane mark section 2 dismantles is provided with the steel bar of covering opening 101. Pouring concrete at opening 101. Therefore, the tower crane mark section wears top structure of the utility model has the beneficial effect of reducing back top construction, saving back top cost, keeping the roof neat.

[0037] The above detailed description is further detailed to the purpose, technical scheme and beneficial effect of the utility model, and it should be understood that the above description is only the specific embodiment of the utility model, and is not used to limit the protection scope of the utility model, and any modification, equivalent replacement, improvement etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
