Description
Technical Field
[0001] This invention relates to the technical field of construction methods for high-rise residential buildings, specifically to a construction method for adjustable tool-type tie rod cantilever disc-lock scaffolding. Background Technology
[0002] With the development of urban construction, high-rise buildings are increasingly common. Modern buildings, especially residential buildings, are mostly shear wall structures. During construction, it is necessary to erect necessary top-mounted cantilevered disc-lock scaffolding on the exterior facade of the building. Currently, common top-mounted cantilevered scaffolding usually adopts a combination structure of disc-lock scaffolding erected on a fixed steel tie rod support frame. The structure of the fixed steel tie rod support frame is as follows: Figure 1 As shown, the fixed steel tie rod support frame 1 includes a scaffolding installation support beam 11, two sets of pre-embedded sleeve-type through-wall bolts 12, an upper tie rod connector 13, a lower tie rod connector 14, an upper tie rod 15, a lower tie rod 16, and turnbuckles 17. One set of pre-embedded sleeve-type through-wall bolts 12 is installed in each of the two adjacent building columns 100. The scaffolding installation support beam 11, used for erecting disc-lock scaffolding, is fixedly installed on the lower building column 100 via the lower pre-embedded sleeve-type through-wall bolts 12. The upper tie rod connector 13 is fixedly installed on the upper building column 100 via the upper pre-embedded sleeve-type through-wall bolts 12. The lower tie rod connector 14 is fixedly mounted on the scaffolding installation support beam 11. The upper end of the upper tie rod 15 is fixedly connected to the upper tie rod connector 13 (usually by welding). The lower end of the lower tie rod 16 is fixedly connected to the lower tie rod connector 14. The lower end of the upper tie rod 15 and the upper end of the lower tie rod 16 are fixedly connected by turnbuckles 17. When the upper end of the upper tie rod 15 extends upward and encounters the protruding panel 101 of the building facade (such as an air conditioning panel or bay window panel), a tie rod through hole 101-1 needs to be opened at the corresponding position on the protruding panel 101 of the building facade before the upper tie rod 15 passes through the tie rod through hole 101-1 and is fixedly connected to the upper tie rod connector 13. The existing structure and construction method have the following shortcomings: First, when the upper tie rod 15 encounters the protruding plate 101 on the building facade, a tie rod through hole 101-1 needs to be opened on the protruding plate 101, which damages the building structure; Second, the upper tie rod connector 13 made of steel plate matching the upper embedded sleeve through-wall bolt 12 and the steel ear plate matching the lower embedded sleeve through-wall bolt 12 are prone to deformation, which makes them inconsistent with the end face of the building column and wall 100, making installation and fixing difficult, affecting the scaffolding erection efficiency and thus affecting the floor construction progress; Third, after the embedded sleeve through-wall bolt 12 fixed on the upper and lower building columns and walls 100 is removed, the building columns and walls 100 are at risk of rainwater leakage; Fourth, the existing fixed steel tie rod support frame 1 has low construction efficiency and high cost due to the limitations of its overall structure. Summary of the Invention
[0003] The purpose of this invention is to provide an adjustable tool-type tie rod cantilever disc-lock scaffolding construction method to solve the problems existing in the prior art.
[0004] The technical solution of the present invention is: the construction method of adjustable tool-type tie rod cantilever disc-lock scaffolding of the present invention includes the following steps: The first step is for the factory to manufacture the various components of the adjustable steel tie rod support frame: According to the design, various components for constructing an adjustable steel tie rod support frame are manufactured in the factory, including a mounting beam, embedded parts, beam fixing screws, upper tie rod connectors, lower tie rod connectors, adjustable tie rods, and tie rod interconnecting threaded sleeves. The mounting beam is made of I-beams welded to mounting seats with screw holes. Two embedded parts with identical structures are provided, each including a threaded sleeve and a set of force arms and mounting arms fixed on both sides of the threaded sleeve. The beam fixing screws are used to cooperate with the threaded sleeves of the embedded parts to fix the mounting beam in place. The upper tie rod connector is an integral part or a fixed part of the screw rod and the U-shaped frame. The connecting components include a U-shaped frame with two connecting pin holes, each fitted with a pin; a lower connecting member consisting of a base plate and two ear plates forming a U-shaped plate structure, with two connecting pin holes on the ear plates for connecting pins; two identical adjustable rods, each including a rod body and a connecting ring integrally or fixedly connected to one end of the rod body, with connecting threads on the other side of the rod body; and a threaded connecting sleeve for connecting rods, which is a cylindrical structure with internal connecting threads, and has a tension adjustment tool insertion hole in the middle. The second step, construction site preparation, includes the following specific steps: ① Remove materials and obstacles from a certain area of the construction floor; ②According to the construction design plan, install and position the components, including the main beam and adjustable tie rod, and make clear markings.
[0005] ③ Transport the construction materials for the adjustable steel tie rod support frame and the disc-lock scaffolding to the construction site; The third step, the installation of the embedded parts of the adjustable steel tie rod support frame, includes the following steps: ① An embedded part is positioned and embedded in the building column or wall below it, with its load arm set longitudinally and its threaded sleeve set horizontally, and tied to the beam reinforcement of the building column or wall. Then the concrete is poured as a whole. ②The other embedded part is positioned and embedded in the upper building column and wall according to the design, with its force arm set horizontally and the threaded sleeve set vertically, and tied to the beam reinforcement of the building column and wall. Then the concrete is poured as a whole. The fourth step, the complete installation of the adjustable steel tie rod support frame, includes the following steps: ① Fixed installation of the main beam: Align the screw hole in the middle of the mounting seat of the main beam with the threaded sleeve of the embedded part on the lower side, and then use the main beam fixing screw to connect the main beam to the embedded part on the lower side and tighten it to fix the main beam on the outer end face of the building column wall located on the lower side. ② Installation of the upper connector of the tie rod: Connect the threaded part of the upper connector of the tie rod to the threaded sleeve of the embedded part on the upper side and tighten it. The opening of the U-shaped frame part of the upper connector of the tie rod should face downward. ③ Installation of the lower connecting part of the tie rod: The lower connecting part of the tie rod is fixedly connected to the upper end face of the mounting beam by welding its base plate at the set position; ④ Initial installation of the adjustable pull rod located at the top: Place the connecting ring of the adjustable pull rod located at the top inside the U-shaped frame part of the upper connector of the pull rod, and use a pin to pass through the two connecting pin holes of the U-shaped frame part and the connecting ring of the adjustable pull rod to connect the adjustable pull rod located at the top to the upper connector of the pull rod. ⑤ Initial installation of the adjustable pull rod located at the bottom: Place the connecting ring of the adjustable pull rod located at the bottom inside the U-shaped frame part of the lower connector of the pull rod, and use a pin to pass through the two connecting pin holes of the U-shaped frame part and the connecting ring of the adjustable pull rod to connect the adjustable pull rod located at the bottom to the lower connector of the pull rod. ⑥ Connect the two adjustable tie rods to the tie rod interconnecting threaded sleeve: Connect the two initially installed adjustable tie rods by using the connecting threads on their rod bodies to the connecting threads inside the tie rod interconnecting threaded sleeve. Connect them to the tie rod interconnecting threaded sleeve from the top and bottom sides. Then, use a tool to insert into the tension adjustment tool insertion hole of the tie rod interconnecting threaded sleeve and rotate the tie rod interconnecting threaded sleeve to tighten the two adjustable tie rods. The fifth step is to fix and install the disc-lock scaffolding on the adjustable steel tie rod support frame.
[0006] A further proposed solution is as follows: the I-beams used to construct the adjustable steel tie rod support frame in the first step are made of Q235B carbon structural steel, and the cantilever length of the installation beam is 1.55m.
[0007] A further solution is as follows: In the first step, each set of support arms and installation arms of the embedded parts used to build the adjustable steel tie rod support frame is made of φ10mm anchor steel bars bent into shape, and the threaded sleeve is a φ20mm straight threaded sleeve. The inner end of the threaded sleeve is equipped with a plastic cap for sealing and preventing leakage.
[0008] A further solution is that the U-shaped frame of the upper connector of the tie rod used to build the adjustable steel tie rod support frame in the first step is made of steel plate with a thickness of 8mm.
[0009] A further solution is: the adjustable tie rods used in the first step to build the adjustable steel tie rod support frame are made of φ20mm Q235B round steel rods.
[0010] Further options include: the threaded sleeve for connecting the tie rods used in the first step to build the adjustable steel tie rod support frame has a length of 600mm and a diameter of 20mm.
[0011] The present invention has the following positive effects: (1) The present invention first installs a new type of adjustable steel tie rod support frame, and then installs disc-lock scaffolding on the adjustable steel tie rod support frame. Compared with the existing upward-pulling cantilever disc-lock scaffolding construction method, it can greatly improve the installation efficiency, effectively shorten the construction period, and save the installation cost. Moreover, the present invention has extremely high adaptability and versatility, which can easily cope with building projects of different heights and shapes. (2) The adjustable steel tie rod support frame of the present invention has a convenient and quick assembly connection between components through the structural design of the embedded parts, the upper connecting parts of the tie rod, the adjustable tie rod, and the interconnecting threaded sleeve of the tie rod. The direction and length of the adjustable tie rod can be flexibly adjusted. When the adjustable tie rod encounters the building facade protrusions such as air conditioning panels and bay window panels, it is not affected at all. Thus, it can effectively solve the technical problem of the existing technology that requires opening tie rod through holes on the building facade protrusions and damaging the building structure. (3) The adjustable steel tie rod support frame of the present invention has its embedded parts embedded in the building columns and walls. It is not removed during disassembly and assembly. The inner end of the threaded sleeve of the embedded parts is sealed with a plastic cap, which can effectively solve the technical problem of rainwater leakage risk in the building columns and walls after the removal of the embedded sleeve-type through-wall bolts in the building columns and walls in the prior art. (4) The adjustable steel tie rod support frame of the present invention has its tie rod upper connecting parts connected to the upper embedded parts by threads. The lower embedded parts are connected to the installation beam through the fixing screw. The installation and connection are very convenient and quick. It can effectively solve the technical problem in the prior art that the upper tie rod connecting parts made of steel plates matched with the upper embedded sleeve-type through-wall bolts and the steel ear plates matched with the lower embedded sleeve-type through-wall bolts are easy to deform and thus do not match the end face of the building columns and walls, making the installation and fixing difficult, affecting the scaffolding erection efficiency and thus affecting the floor construction progress.
