Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a method of constructing a building, and more specifically, the present invention relates to a method of constructing a building. This article relates to construction methods for buildings, steel towers, bridge piers, etc., which are assembled from the upper layer and then jacked up one after another.

(Prior art and its problems) In recent years, automation of construction work using robots and the like has been promoted in the construction industry, but these have only been applied to a small part of the entire process, and robots 1 to 1. At present, we have not yet reached the point where we can fully enjoy the benefits of This phenomenon is not due to a lack of efforts in robotization, but is due to the uniqueness of the working environment in the construction industry, in which the workplace moves up, down, left, right, or forward. it is conceivable that. For example, in the case of building construction, in the case of the so-called SRC structure, the framework is assembled from the lower floors and moved to the upper floors one after another, so it must be linked with crane work, and at the time of this crane work, a continuous system The flow will be interrupted.

In addition, another method has been proposed in which a building is constructed by first building pillars and placing jacks near the tops of the pillars, and then lifting the roof or floor dyeing that has been raised on the ground using a crane. This method had the disadvantage that it was difficult to apply to multi-story buildings.

Historically, in the past, large cranes and shoring were generally required, and work on high scaffolding was essential, which caused problems in terms of the economic efficiency of the equipment and the safety of the work.

(Object of the invention) The present invention has been proposed to solve the above-mentioned drawbacks.
The purpose is to assemble the structures such as the pillars, dyeing, and floors (ridges) that make up each floor from the top floor in a work space near the ground surface, and then jack up this structure and sequentially build it up. By shifting to the construction of floors, there is no need for large cranes, high scaffolding, or support, and it is economical and safe, and it is also possible to use robots for construction work. The purpose of this invention is to provide a construction method for compact buildings.

(Structure of the Invention) The present invention will be described below with reference to the drawings. First, FIG. 1 shows an embodiment of the assembly frame according to the present invention, and in the figure, 1 is a garden floor formed on the foundation work,
On top of this floor 1 is a hollow frame column 2/' made of TI4 or the like.
f - constructed. This pedestal column 2 has vertical members 2a erected at each of the four corners, and the surrounding three sides except the front are shown in Fig. 1 (b).
As shown in the figure, a horizontal member 2t+ and a diagonal member 2C are arranged to connect the vertical member 21I to the phase n, and in front of the frame column 2, a plurality of P plates 2 (1 is a bolt, 1 is a bolt, It is removably attached with a nut.Here, the frame column 2
The internal space of 3. The size is set to accommodate the spacer 4 and the column member 5, and the insertion and removal of these members and the operation of the support nut 14, which will be described later, are performed by appropriately removing the flat plate 2d.

In addition, two vertical members 2a arranged on both sides of the front of the pedestal column 2
6 stiffeners 2e are removably provided as needed,
The strength of the pedestal column 2 can be improved. Further, on the inner surface of the frame column 2, a column member 5 is attached when the shirt 1 is put up.
In order to prevent eccentricity from occurring, guide rails 2t are attached at necessary locations to correct the clearance between the supporting hardware 7 and the guide hardware 8 attached to the column member 5 shown in FIG. 1(C). As shown in FIG. 1(E), a temporary support plate 9 is attached to the upper end of the pedestal column 2 in order to support the temporary reaction force during jacking up.

Here, the support hardware 7 and the guide hardware 8 are made of a structure that can resist the lateral load received during construction together with the eccentricity ti 11 of the column member 5 described above, as an integral structure with the assembly frame. Figure 1 (C1.Fi and Section 21 below)
As shown in 2!1, former NI? It can be detachably attached to the side of J5 or the bottom of J5 using the removable bolt 10 if necessary (=
It's something that can be kicked. An anti-friction material 11 such as Teflon is attached to the contact surfaces of both the support hardware 7 and the guide hardware E3 with the guide rail 2t in order to reduce the frictional resistance generated in each member 1ffl during jacking up.

In addition, in Fig. 1, 12 is Anno'-Bolt, 13 is
14 indicates a temporary support spindle, 14 a support nut, 15 a temporary support nut h, and 1G the mount east.

Next, the present invention will be explained in detail with each step shown in FIG. As shown in Figure 2 (a), the foundation for the building and the bottom part 1 of the floor 1 are constructed using the anchor bolts 12 to assemble the pedestal consisting of the pedestal pillar 2 and the pedestal frame H4. and install it on floor 1. At this time, it is convenient to use the assembly frame as the structure of the Fl@- after completion, and considering that it is necessary to temporarily support the model car of the structure at any time during jacking up until completion, It is necessary to create a structure that fully supports the entire structure of the building and is sufficiently safe against tfA loads caused by earthquakes, wind pressure, etc. There's grass.

Next, a shirt 4:3, which is moved up and down by hydraulic pressure, is installed in the inner space of the frame column 2, and a spacer 4 is attached to the top of the shirt 4, if necessary. Furthermore, a column member 5, which will become a column for the top floor of the building, is placed on the upper surface of the base 114, and a beam member 18 and a roof member 19 are connected to this column member 5, and the bolts 20, 21 and adhesive are used to connect each column member 5 to the column member 5. to be united.

After finishing the %1 chapter in this way, as shown in Figure 2 (01), the top floor structure of the building is pushed up as a whole by pressing and expanding one set of jacks 3. Upon completion of the alignment, the temporary support nut 1:) is tightened and the building 1@ is supported on the assembly frame via the temporary support support root 9 by the support nut 14 and temporary support spindle 13. Scold 1
Retract the jack 3, remove the spacer 4, and insert the next column member; Once inserted, the LAL valve part is connected with bolts 20 and adhesive.

Next, from the state shown in Fig. 2 (c), extend the V3 by 1 ltl to remove the structure! Bonds that can be supported by Jyatsuki 3, installation pole!・Remove the support metal fittings 7 and guide metal fittings 8 attached by 10, and at the same time loosen the temporary support nuts 15 and support pieces 1 to 14 to make the temporary support spindle 13 movable up and down. Attach the support metal 1!57 and guide hardware ε3 that were removed in this way to the side of the newly added column member 5^ using the pole]・1().
At the same time, install the temporary support plate 1"1!i, the support pin 1-14, the temporary support spindle 13, etc. from the temporary support plate 9 upward so as not to interfere with the work in the next process. It is necessary to adjust the protrusion length of the temporary support spindle 13,
This work is carried out by loosening the temporary support nuts 15 and support nuts 1-14 and changing the position of the temporary support spindle 130.

Next, the jack 3 is extended while tightening the temporary support nut 15, and when the jack 3 reaches the top dead center as shown in FIG. Temporarily receive it on the stand. Thereafter, the jack 3 is retracted and the spacer 4 is inserted as shown in FIG. 2 (B), and the same steps as described above are repeated in the order of FIGS. 2 (F) to (H). In addition, in FIGS. 2(g) and 2(h), 5B indicates a column member. .

In this way, as shown in FIG. The members 2:S are fastened together using bolts 24 and adhesive to complete the assembly of this floor. After that, the jack 3 is extended again to become the state shown in Fig. 2 (N), that is, the state shown in Fig. 2 (B) or Fig. 2 (F) in the assembly process of each floor, and these steps are repeated. Then, each floor of the building was finished and jacked up in sequence from the top floor.Finally, the assembly pedestal consisting of 2 trestle pillars and 16 Kuridai prefectures was used as the pillar of the chain lower cabinet floor and the steel frame of the raku. The building will be completed by pouring concrete into these areas.

Although this embodiment shows the case where the present invention is applied to a building structure, the present invention can also be widely applied to the construction of steel or concrete structures such as steel towers, chimneys, and bridge piers. It is something that can be done.

(Effects of the Invention) According to the present invention, as on the base, a column member is arranged inside a hollow pedestal column erected on the floor of the lowest floor, and a beam member and a roof 1 are attached to this column member. It consists of a step of binding together members or floor materials to form a one-story structure, and a step of jacking up this structure and then temporarily supporting it.While repeating each of the above steps, Since the construction was done sequentially from the bottom 81 sections, the work space was from the subcontractor's floor to the height of the second floor, and as with the conventional construction method, there was a large crane used to lift heavy objects to high places, and the top floor was This has the effect of reducing construction costs as it does not require scaffolding or shoring.

Furthermore, since work at heights can be avoided, work safety can be improved.

In addition, since each floor is jacked up with the exterior walls and floors finished, the lower floors are less affected by the weather, and this lower floor can be used as an all-weather assembly workshop, ensuring reliable process control. In addition, it is possible to use the assembly stand as a scaffold or support for the lowest structure or automatic equipment such as robots, making it easier to automate construction work. effective.

Additionally, since there is no crane work involved in each process, construction can be carried out smoothly without disrupting the continuity of work, shortening the construction period, and making it easy to construct multi-story buildings. It has the following advantages.
