[0002] The construction of vehicle bases has difficulties such as large scale, multiple professions, complex processes and tight construction period. In order to ensure that the transportation of vehicle base materials can meet the needs of vehicle base construction, tower crane transportation is the main form of vehicle base material transportation. The tower crane in tower crane transportation is the main vertical transportation tool for engineering construction. It has strong transportation capacity and maneuverability. At the same time, due to the large space of public buildings, in order to improve the efficiency of tower crane construction, the tower crane will inevitably be arranged in the beam and slab part in the middle of the structural structure during specific use. At the same time, in order to facilitate the dismantling of the tower crane in the later stage, this beam and slab part will inevitably reserve a tower crane opening, and the opening sealing after the tower crane is dismantled requires secondary pouring construction.

[0003] In the construction project of the vehicle base, due to the particularity of the vehicle depot construction, the construction under the cover will be carried out after the cover construction is completed. How to ensure the continuity of the construction under the cover will be an important measure to ensure the project schedule. Because the traditional large-scale vehicle base has a large cover area and a large number of tower cranes during the construction process, the traditional tower crane needs to erect a large bracket in the basement space under the cover to support the overall structural sealing of the opening when sealing the opening, which is time-consuming and labor-intensive, and seriously affects the construction period.

[0004] To this end, the present application specifically proposes a tower crane opening without a bracket to seal the component, so as to solve the above-mentioned technical problems. Utility Model Content

[0012] The bent steel plates are distributed in an array with equal spacing above the template body, and the bent steel plates have the same bending direction, so that the I-beam body passes through the through holes formed below the bent steel plates in the same row or column.

[0013] Furthermore, the connecting member includes a screw that is threadedly rotated through the bent steel plate, a rotating torsion block arranged at one end of the screw and a limit block arranged at the other end of the screw, and the limit block is rotatably arranged inside the template body.

[0014] Furthermore, a central groove body is provided on the upper surface of the template body and is located below the opening body, and the support assembly is arranged inside the central groove body.

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0036] In the first embodiment, see Figures 1 to 5 .

[0037] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the utility model provides a tower crane hole plugging component without a bracket, which is used for concrete pouring and plugging of a tower crane hole body 1, and includes:

[0038] The template body 2 has an upper surface that fits under the opening body 1. The template body 2 is used to cooperate with the opening body 1 to weave steel bars and cast concrete in the opening body 1.

[0039] A plurality of I-beam main bodies 5 are arranged above the opening main body 1 . The I-beam main bodies 5 are connected to the formwork main body 2 through a plurality of supporting components, so as to support the formwork main body 2 below the opening main body 1 .

[0040] In the specific implementation, an I-beam main body 5 is erected above the opening body 1, and the formwork main body 2 is supported below the opening body 1 by a supporting assembly. At this time, the corresponding steel structure can be compiled and installed in the opening body 1 to carry out concrete pouring and sealing operations on the tower crane opening body 1.

[0041] It should be noted that at this time, both ends of the multiple I-beam main bodies 5 are erected on the upper surface of the opening main body 1 , which can ensure the stability of the support installation of the template main body 2 below the opening main body 1 .

[0042] Since the formwork body 2 is supported below the opening body 1 by the I-beam body 5, and the formwork body 2 is used to cooperate with the opening body 1 to complete the concrete pouring and sealing of the tower crane opening body 1, there is no need for bottom support when pouring the sealing concrete. This makes it convenient to support the concrete poured in the tower crane opening and to quickly disassemble it after the concrete is cured and formed, which is convenient to use, improves the overall construction progress of the project, and effectively alleviates the problem that traditional bracket components need to be set up by workers at the bottom of the cover plate, thereby occupying a large amount of space under the cover plate.

[0043] It should also be noted that the formwork body 2 here is set as a steel formwork, which has the characteristics of simple structure, easy adjustment and long service life, and is suitable for concrete support of a larger tower crane opening body 1.

[0044] However, it should also be noted that when a steel formwork is used for the formwork body 2, it is necessary to ensure that the cover plate has good load-bearing conditions at this time, and when it comes to smaller openings on the cover plate, wooden formwork can also be used to support the pouring of concrete.

[0045] Specifically, Figure 2 As shown, the support assembly includes:

[0046] A plurality of bent steel plates 3 are mounted on the I-beam main body 5 and the two ends are mounted on the template main body 2 through connectors 4. The bent steel plates 3, the connectors 4 at the two ends of the bent steel plates 3 and the template main body 2 form a through hole for the I-beam main body 5 to pass through.

[0047] The bent steel plates 3 are arranged in an array with equal spacing above the template body 2 , and the bent steel plates 3 are bent in the same direction, so that the I-beam body 5 passes through the through holes formed below the bent steel plates 3 in the same row or column.

[0048] Therefore, by installing the formwork body 2 using a plurality of I-beam bodies 5 and supporting components, the stability of the formwork body 2 can be improved, and the overall load-bearing capacity of the formwork body 2 can be enhanced when the tower crane opening body 1 is sealed with concrete.

[0049] Furthermore, the connecting member 4 includes a screw rod 41 that is threadedly rotated through the bent steel plate 3 , a rotating torsion block 43 arranged at one end of the screw rod 41 , and a limit block 42 arranged at the other end of the screw rod 41 , and the limit block 42 is rotatably arranged inside the template body 2 .

[0050] In the specific implementation, by rotating the torsion block 43 to control the screw 41 to rotate through the bent steel plate 3, the bent steel plate 3 can be controlled to rise and fall above the formwork body 2. In conjunction with the I-beam beam body 5, it can be suitable for covering tower crane openings of different thicknesses to provide fitting support for the formwork body 2 when sealing concrete pouring, which is convenient for use according to different construction environments.

[0051] In addition, it can be additionally explained that the screw 41 here can adopt the structure of a water-stop screw (refer to Figure 2 ), since a water stop ring is arranged in the middle of the screw, it can also play a waterproof role when pouring concrete.

[0052] In the second embodiment, see Figure 6 and Fig.10 .

[0053] Based on the above embodiments, the utility model proposes a tower crane hole plugging component without a bracket, which is used for concrete pouring and plugging of a tower crane hole body 1, comprising:

[0054] The template body 2 has an upper surface that fits under the opening body 1. The template body 2 is used to cooperate with the opening body 1 to weave steel bars and cast concrete in the opening body 1.

[0055] A plurality of I-beam main bodies 5 are arranged above the opening main body 1 . The I-beam main bodies 5 are connected to the formwork main body 2 through a plurality of supporting components, so as to support the formwork main body 2 below the opening main body 1 .

[0056] The difference from the first embodiment is that:

[0057] like Figures 6 to 10 As shown, the upper surface of the template body 2 is provided with a central groove body 21 located below the opening body 1, and the supporting assembly is arranged inside the central groove body 21, the outer edge of the template body 2 is matched with the central groove body 21 to be arranged as an eaves board part 23, and the upper surface of the eaves board part 23 is fitted and arranged below the opening body 1.

[0058] Specifically, the central trough body 21 is used to facilitate the installation of multiple supporting steel bars inside. At this time, by setting the formwork body 2 to consist of the central trough body 21 and the eaves plate portion 23, and installing steel bars are pre-installed in the central trough body 21, the overall strength of the concrete blockage after pouring can be ensured when pouring the tower crane opening, thereby improving the safety of the cover plate when bearing gravity.

[0059] Furthermore, the eaves plate portion 23 is fixedly installed below the opening body 1 by bolts 22, which can conveniently improve the connection strength of the formwork body 2 when installed below the tower crane opening body 1, and improve the concrete pouring bearing capacity of the formwork body 2.

[0060] In the third embodiment.

[0064] S3. The template is supported and fixed on the cover plate in reverse: the I-beam body 5 is used to cooperate with the bent steel plate 3 to fix the overall template body 2 in reverse support on the cover plate;

[0065] S4. Concrete roughening and steel bar tying: roughening the concrete around the main opening 1, and tying steel bars on top of the formwork body 2 according to the structure of the main I-beam 5;

[0066] S5. Concrete pouring and concrete curing: pouring concrete on the inside of the main body 1 of the tower crane opening above the main formwork body 2, and performing concrete curing;

[0067] S6. Overall lifting and removal of the formwork: After the concrete strength reaches the standard, the main body of the formwork is removed as a whole, and the concrete pouring and sealing operation of the tower crane opening can be completed.
