Description

Technical Field

[0001] The present invention relates to the technical field of the installation and construction of residential building machines, and particularly relates to an installation and construction method and structure of a residential building machine. Background Art

[0002] The hanging frame system of a residential building machine mainly consists of a hanging head, a suspension rod, a connecting splint, a walkway board, a cross beam, etc. Different from a climbing frame, the external protection frame of a residential building machine adopts a hanging design, and the entire frame is suspended under the lower chord of a Bailey truss through a hanging head. The traditional suspension rod is designed as 50×50×4, and the walkway board is designed in two forms: diamond steel plate mesh and lenticular pattern steel plate.

[0003] When the traditional hanging frame system is designed, in order to meet the requirements of main structure construction and lean construction, the total height of the entire frame is 17.23m, and a total of 8 layers of walkway boards are set. The height of each layer of the hanging frame (counting from top to bottom) is 2m for the first layer, 2.23m for the second layer, 2m for the third layer, 2m for the fourth layer, 3m for the fifth layer, 2m for the sixth layer, 2m for the seventh layer, and 2m for the eighth layer. The suspension rod is formed by butt-jointing 3 square tubes.

[0004] Its installation sequence is: hanging head → suspension rod → cross beam → walkway board → external protection mesh. Since the external protection hanging frame needs to be installed after the installation of the Bailey truss of the residential building machine, and the residential building machine is usually installed after the completion of the second-layer structure of the main structure construction. Therefore, when constructing the first and second floors of the main structure, it is necessary to first set up an external protection floor-standing steel pipe scaffold for the main structure construction, and when the residential building machine starts to install the external protection hanging frame, the floor-standing scaffold is demolished. This construction method has the following problems:

[0005] 1) The hanging frame adopts a hanging design. During installation, it is necessary for workers to use a winch or pulley to lift the suspension rod from the ground upwards manually, and then the construction workers operate inside the Bailey truss to install the combination of the suspension rod and the hanging head. This construction process is cumbersome and has a relatively high risk factor;

[0006] 2) When installing the hanging frame, it is necessary to demolish the floor-standing scaffold in advance. At this time, there are no protective facilities around the floors, balconies, etc., posing certain safety hazards;

[0007] 3) Manually using a pulley to lift the suspension rod for installation requires a large number of construction workers. Generally, 2 - 3 people are needed inside the truss, and 5 - 7 people are needed for the ground lifting. The construction cost is high and the installation time is long;

[0008] 4) When installing the external hanging frame, it is necessary to demolish the floor-standing scaffold, and the installation time of the hanging frame is relatively long. During this process, the main structure cannot be constructed, affecting the construction period of the main structure and easily causing late-stage main labor claims.

[0009] In summary, for the traditional hanging-type installation of the external protection hanging rack of the residential building construction machine, the hanging rack is prone to conflict with the floor-standing steel pipe scaffold, which affects the installation construction of the suspender. Moreover, the amount of high-altitude work is large, the construction is inconvenient, and the safety risk is high. Summary of the Invention

[0049] As Figures 1 to 10 shown, the present invention provides a method for installing and constructing a residential building construction machine, including the following steps:

[0050] S1. After the top plate construction is completed, position and set out the lines, mark the positions of each suspension rod, and set the installation points of the suspension rods according to the projection positions of the hanging heads 9;

[0051] S2. Place the middle suspension rod 1 according to the positions located by the setting out, and at the same time install the walkway cross beam 2. After the installation of the cross beam 2 is completed, install the walkway board;

[0052] S3. Reserve sleeve holes at the shear wall and / or balcony positions at the segmented locations for installing the connecting wall members 3.

[0053] S4. After the construction of the first-floor structure is completed, start installing the upper suspension rods 5, as well as the corresponding cross beams and walkway plates, and then carry out the construction of the second-floor main structure.

[0054] S5. After the construction of the second-floor main structure is completed, start the installation work of the residential building construction machine 4.

[0055] S6. When the Bailey truss and the hanging heads of the residential building construction machine are installed, use the lifting device to lift the external protection hanging rack upward in segments, and then connect the upper suspension rod with the hanging head.

[0056] S7. Carry out the construction of the third-floor structure, and after the construction is completed, carry out the first jacking of the residential building construction machine 4.

[0057] S8. Install the lower suspension rod 7.

[0058] S9. Carry out the second jacking of the residential building construction machine 4. After the jacking, complete the installation of the cross beam 2, walkway plates and external protection mesh sheets of the lower suspension rod 7, that is, the installation of the entire external protection hanging rack is completed; then carry out the normal construction stage of the main structure.

[0059] The above scheme changes the previous installation method of the external protection hanging rack (referred to as the hanging rack), and uses the hanging rack instead of the floor-standing scaffold, that is, during the construction of the main structure, the external protection hanging rack of the residential building construction machine 4 is used as the floor-standing external protection operation scaffold. The external scaffold of the residential building construction machine 4 mainly includes suspension rods, cross beam 2, and walkway plates; the suspension rods are composed of 3 upper, middle and lower suspension rods connected together. Among them, the length of the upper suspension rod 5 is 5.5m, the middle suspension rod is 6m, and the lower suspension rod is 6m. The specific construction steps are as follows:

[0060] 1) Positioning and setting out: According to the external scaffold design drawing, after the construction of the roof slab is completed, carry out positioning and setting out, and set the installation points of the suspension rods according to the projection position of the hanging head 9. When setting out on site, mark the position of each suspension rod.

[0061] 2) Hanging rack installation: Only install the middle suspension rod 1 during the first installation. The length of this suspension rod is 6m. Place the middle suspension rod 1 according to the position determined by the setting out, and at the same time install the walkway cross beam 2. After the installation of the cross beam 2 is completed, install the walkway plates. During the installation process, it is required to install the standard walkway plates and the corresponding suspension rods first, and it is required to continuously install 3 spans to ensure the stability of the frame body. Install the walkway plates and the outer protection mesh sheets layer by layer from bottom to top.

[0062] 3) Connecting wall member 3 setting: The connecting wall member 3 is set considering two steps and two spans, and at the same time considering the temporary tying measures during the later segmented lifting of the hanging rack. Reserve sleeve holes at the shear wall, balcony and other positions at the positions that need to be segmented for installing the connecting wall member 3.

[0063] 4) Installation of the upper suspension rod 5: After the construction of the first - floor structure is completed, the upper suspension rod 5 is installed, and then the construction of the second - floor structure is carried out.

[0064] 5) Installation of the residential building construction machine 4: After the construction of the second - floor main structure is completed, the installation work of the residential building construction machine 4 is started, including the installation of the support system, power and control system, steel platform system, formwork system, safety protection system, etc. A lifting device is installed at the lower end of the Bailey truss 8.

[0065] 6) Lifting of the hanging scaffold: After the installation of the Bailey truss of the residential building construction machine 4 is completed, the external protection hanging scaffold is lifted through the lifting device. Specifically, the lifting device is mainly an electric hoist 6. The upper end of the electric hoist 6 is hung under the Bailey truss through a hook, and the lower end of the electric hoist 6 is tied at the intersection position of the upper suspension rod 5 and the cross - beam 2 on the inner and outer sides of the hanging scaffold. Driven by the electric hoist 6, the hanging scaffold is lifted upward in sections. During the installation process, the frame body of the external protection hanging scaffold cannot be lifted upward synchronously. Only after one section is installed can the next section be lifted and installed. However, each section of the frame body is lifted by 4 electric hoists 6, and the electric hoists 6 need to perform lifting operations synchronously to ensure the stability of the frame body. After the first section, that is, the section where the upper suspension rod 5 is located, is lifted, the upper suspension rod 5 is connected to the corresponding hanging head 9. The hanging heads 9 are all installed on the lower chord of the Bailey truss 8 and are connected to the upper suspension rod 5. Its function is to hang the upper suspension rod 5 under the Bailey truss 8.

[0066] Among them, the external protection hanging scaffold is lifted upward in sections. Each section of the external protection hanging scaffold is installed with 4 electric hoists 6, which are located at the four corners of the external protection hanging scaffold. That is, electric hoists 6 are installed at the upper ends of the upper suspension rods 5. The lower ends of the electric hoists 6 are all connected to the intersection positions of each suspension rod and the cross - beam. During lifting, synchronous operation is required to ensure the stability of the frame body.

[0067] 7) Construction of the third - floor structure: After the hanging scaffold is lifted, the construction of the third - floor structure is carried out. After the construction is completed, the first jacking of the residential building construction machine 4 is carried out.

[0068] 8) Installation of the lower suspension rod 7: After the first jacking of the residential building construction machine 4, the installation of the lower suspension rod 7 of the hanging scaffold is carried out. Only the suspension rod is installed in this installation, and the cross - beam 2 and the walkway board are not installed. The upper end of the lower suspension rod 7 is hung on the lower end of the middle suspension rod 1, the upper end of the middle suspension rod 1 is hung on the lower end of the upper suspension rod 5, and the upper end of the upper suspension rod 5 is hung on the hanging head 9. The suspension rod includes a hanging head 9, an upper suspension rod 5, a middle suspension rod 1, and a lower suspension rod 7 that are hung in sequence from top to bottom.

[0069] 9) Jacking of the building construction machine: When the construction of each floor structure is completed, the second jacking of the residential building construction machine 4 is carried out. After the jacking, the installation of the lower suspension rod 7, the cross - beam 2, and the walkway board is completed. After the installation is completed, the overall installation of the residential building construction machine 4 is completed, and it enters the normal construction stage.

[0070] The embodiment of the present invention also provides an installation and construction structure for a residential building construction machine 4, which includes the residential building construction machine 4 and also a suspension rod. A cross beam 2 is installed on the suspension rod, and a walkway board is installed on the cross beam 2. One end of the cross beam 2 is connected to the wall through a coupling member 3. The suspension rod includes an upper suspension rod 5, a middle suspension rod 1, and a lower suspension rod 7 that are sequentially hung from top to bottom.

[0071] Among them, a cross beam, a walkway board, and an outer protection mesh are installed on each of the suspension rods. The cross beam plays a role in transverse connection. The walkway board is for the staff to walk on, and the outer protection mesh is for safety protection to prevent objects from falling outside.

[0072] Beneficial effects:

[0073] 1) Using the outer protection hanging rack of the residential building construction machine instead of the floor-type steel pipe scaffold can reduce the erection and demolition processes of the steel pipe rack, and reduce the steel pipe rental and construction costs;

[0074] 2) After using the outer frame of the residential building construction machine as a floor frame, after the later-stage Bailey truss of the residential building construction machine is installed, it is only necessary to use an electric hoist to lift the hanging rack upward as a whole in sections, which can greatly accelerate the construction period of the residential building construction machine;

[0075] 3) The outer protection hanging rack of the residential building construction machine adopts a lower hanging design. After using the hanging rack instead of the outer frame, it is possible to avoid installing the hanging rack from top to bottom in the later stage, reduce the amount of high-altitude work in the later stage, and reduce the safety risks during the construction process.

[0076] The above is only a preferred embodiment of the present invention, and it is not intended to limit the present invention in any form; any ordinary technical personnel in this industry can smoothly implement the present invention according to the illustrations in the specification and the above description; however, any slight changes, modifications, and equivalent changes made by those skilled in this profession within the scope of the technical solution of the present invention by using the technical content disclosed above are all equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications, and evolutions made to the above embodiments based on the essence of the present invention still fall within the protection scope of the technical solution of the present invention.
