[0002] With the development of China's construction industry, the state encourages the adoption of prefabricated building technologies in newly built buildings to improve the level of building industrialization and intelligence. At the same time, the attached lifting scaffold increasingly highlights its advantages in economy, safety, efficiency, etc. in high-rise buildings, and also conforms to the policy of building a conservation-oriented and low-carbon society in China. Therefore, it is becoming more and more popular and widely used in high-rise buildings.

[0003] In recent years, in order to shorten the construction period and improve efficiency, many companies have proposed the cross-construction method of the lifting scaffold anyway. However, in the implementation process, it often intervenes from the design stage, adopting a fully concrete exterior wall and some secondary structures poured together with the main body at one time. This method has a low assembly rate and is prone to affecting the construction of the secondary structure on the exterior facade. Therefore, it does not conform to the national development direction of prefabrication and has great limitations. Summary of the Utility Model

The construction structure includes a climbing frame 1 connected to the main structure 14 through a climbing frame attachment support; a construction elevator guide rail frame 4 connected to the main structure 14 through a first attachment frame 100. Among them, the construction elevator guide rail frame 4 is also connected to the climbing frame 1 through a second attachment frame 200, and the climbing frame 1 is connected to the main structure 14 through the second attachment frame 200; the climbing frame attachment support includes a heightening piece 23 located inside the secondary structure 18 of the building; a climbing frame attachment frame extension piece 19 fastened to the top of the heightening piece 23 through a screw rod 22; and a tie rod 20 connecting the climbing frame attachment frame extension piece 19 and the precast shear wall 21.

[0040] In this embodiment, a tie rod hole (not shown) is reserved in the precast shear wall 21, and a diagonal steel bar 201 is arranged in the tie rod hole. One end of the diagonal steel bar 201 is connected to the climbing frame attachment frame extension piece 19 through a tie rod 20.

[0041] In this embodiment, the screw rod 22 includes a first screw rod 221 and a second screw rod 222. The first screw rod 221 passes through the climbing frame attachment frame extension piece 19 and the heightening piece 23 and fixedly connects the two, and the second screw rod 222 passes through the other end of the climbing frame attachment frame extension piece 19 and the main structure 14 and fixedly connects the two.

[0043] In this embodiment, one end of the climbing frame attachment frame extension piece 19 exposes the vertical plane where the exterior facade is located and is connected to the climbing frame.

[0044] In this embodiment, asFigure 7 As shown in the figure, the second wall-attached frame 200 includes a main frame 5 fixed to the climbing frame 1; a connecting rod 9 connecting the main frame 2 and detachably connected to the main structure 14; and an adjusting mechanism adjustably installed on the main frame 5 and detachably connected to the construction elevator guide rail frame 4; the locking and unlocking between the second wall-attached frame 200 and the main structure 14 and the construction elevator guide rail frame 4 are realized through the connecting rod 9 and the adjusting mechanism before and after the climbing frame 1 is lifted.

[0045] In this embodiment, reinforcing ribs are respectively arranged on both sides of the main frame 5, and the reinforcing ribs include a horizontal reinforcing rib 51 and an inclined reinforcing rib 52.

[0048] In this embodiment, the main frame 5 is provided with multiple pairs of bearing holes 8 for selectively inserting the bearing rod 7.

[0049] The characteristics and functions of the present utility model are further understood through the following description.

[0050] First of all, it should be noted that this embodiment provides an assembly-type high-rise building climbing frame synchronous engineering construction method. For single buildings with a relatively high prefabrication rate, in high-rise buildings with a large number of PC components, the form of the climbing frame 1 used is improved, and an adjustable construction elevator wall-attached frame is adopted, so that the construction elevator 3 can enter the climbing frame 1 to timely transport the materials required for subsequent processes to the working surface; at the same time, the installation form of the climbing frame wall-attached support is designed to ensure that the external wall construction will not be affected and the synchronous project can proceed smoothly.

[0051] As Figure 2-7 shown, the bottom of the N-4th floor is the factory-supplied wall-attached frame (i.e., the first wall-attached frame 100), and the bottom of the N-1st floor is the construction elevator wall-attached conversion connection wall-attached frame (i.e., the second wall-attached frame 200) of this embodiment. At this time, the distance between the two wall-attached frames meets the requirements.

[0052] Furthermore, the second wall-attached frame 200 mainly includes a main frame 5, an adjustable arm 6, a bearing rod 7, a bearing hole 8, a connecting frame 9, and an adjusting bolt hole 10.

[0053] Furthermore, as Figure 2 and Figure 3As shown, before the lifting of the climbing formwork 1, the restraint between the second attached wall frame 200 and the main structure 14 and the construction elevator guide rail frame 4 is released, and the climbing formwork 1 is lifted.

[0054] Further, as Figure 4 and Figure 5 shown, after the lifting of the climbing formwork 1, the first attached wall frame 100 is installed. When the N - 1th floor becomes the next N - 4th floor as the climbing formwork 1 is lifted, the next cycle is entered.

[0055] Further, the construction elevator guide rail frame 4 is always located outside the climbing formwork 1. The standard section of the construction elevator is 1.5 meters, the distance between two adjacent attachment frames shall not exceed 10.5 meters, and the height of the guide rail frame above the uppermost attached wall frame shall not exceed 7.5 meters (including the top section, and the top section has no rack), and the minimum over - topping height is 4.5 meters (the distance from the highest position of the construction elevator to the top of the guide rail frame).

[0056] Further, as Figure 1 shown, it is necessary to strengthen the structure above the reserved notch 300 position of the climbing formwork 1. The strengthening method is to set up a horizontal truss 2, and the horizontal truss 2 is arranged at the 4th step of the climbing formwork.

[0057] As Figure 8 shown, in a synchronous engineering construction method for the climbing formwork of an assembled high - rise building provided in this embodiment, the installation of the climbing formwork attached wall support shall not affect the synchronous construction of the outer facade. Therefore, a method of heightening and upward pulling installation is adopted.

[0058] Specifically, pull rod holes (not shown) should be reserved in advance on the precast shear wall 21. 4 inclined steel bars 201 are arranged around the pull rod holes for strengthening. The pull rod holes should be arranged between 100 - 300 mm below the floor slab 400, and the installation of the pull rod 20 does not affect the passage of personnel in the open corridor.

[0059] Further, two screw rods 22 (the first screw rod 221 and the second screw rod 222) are installed inside the building structure for the climbing formwork attached wall lengthening piece 19. Among them, the distance between the first screw rod 221 and the tail of the climbing formwork attached wall lengthening piece 19 is not less than 200 mm, and the middle screw rod passes through the heightening piece 23.

[0060] Further, the parapet is the secondary structure 18. The position of the heightening piece 23 should be accurately laid out in advance, close to the parapet, and should be slightly higher than the parapet to ensure that the outer end of the climbing formwork attached wall lengthening piece 19 is upturned after installation.

[0061] As Figure 9 shown, in a synchronous engineering construction method for the climbing formwork of an assembled high - rise building provided in this embodiment, any floor of the assembled building structure is defined as the Nth floor, and the X floors below the Nth floor are the N - Xth floors; among them, the construction steps of each floor are independent and simultaneous, and the construction content of each floor is as follows:

[0062] 1) Nth floor: The floor for construction operations to be built.

[0063] 2) (N - 1)th floor: Formwork support system.

[0064] 3) (N - 2)th floor: Removal of formwork and supports.

[0065] 4) (N - 3): Sanitary cleaning and layout positioning.

[0066] 5) (N - 4)th floor: Construction of the secondary masonry structure on the exterior facade.

[0067] In summary, the construction structure of the present utility model is mainly aimed at high-rise buildings with a large number of PC components. By means of an adjustable construction elevator attachment frame, the construction elevator can enter the bottom two floors of the climbing frame, effectively transporting materials to the working surface, completing synchronous project construction, avoiding the appearance of "reverse walls", greatly improving the masonry quality, reducing the vertical transportation pressure, and providing more favorable conditions for the hoisting of PC components. At the same time, through a special design of the installation form of the climbing frame attachment support, on the premise of safe use, it is ensured that the construction of the secondary structure on the exterior facade is not affected, thus realizing synchronous project.

[0068] The above is only a preferred embodiment of the present utility model, and thus does not limit the implementation manners and protection scope of the present utility model. For those skilled in the art, it should be able to realize that all equivalent replacements and obvious changes made by using the description and illustration content of the present utility model should be included within the protection scope of the present utility model.
