At the stage when the construction of one floor is completed, all of the temporary columns 1 supporting the temporary shed T are in the state of the temporary columns 1a shown in FIG. Extend the pillars 1 all at once, keeping the difference in rising speed as small as possible and within the allowable limit, to the state of the temporary pillar 1c.
As a result, for the next construction work, space A is secured, and the temporary shed T is constructed in the same manner as above, and the temporary shed T is sequentially moved horizontally to proceed with construction and spirally move upward to the required number of layers. Construction of the structure will continue. b: In process diagram 2 of the method of assembling the permanent structure, after the foundation part (not shown) of the construction structure is completed, the temporary shed T is assembled, and after the necessary functions can be performed, the planned site is first constructed. From the outside, the pillars 34 of the main structure S are mounted on a crane C and attached to the arm 38 and its tip of a work robot that operates in response to commands from the control room R or commands from a push button switch (not shown), etc. It is gripped by the gripping mechanism 39, and installed and fixed in a predetermined position by a series of these operations.

[0010] At this time, as shown in street C in Fig. 2, the temporary pillar 1 becomes a corner, so it is shortened to the state 1b as shown by the dotted line, and the above-mentioned permanent pillar material 34 is installed in that space. . Next, the temporary column 1 is extended again, and the load is supported by the top of the previously installed column material 34, so that the temporary column 1 becomes the temporary column 1a. After installing a plurality of pillars 34 using this method, a beam 35 is installed and fixed at a predetermined location on the top of the pillar 34 that has been completely installed. The beam material 35 is transported, installed, and fixed using the pillar material 3.
The flooring material 36, wall material 37, and other members for special parts such as stairs and elevators are also installed by the same method as in step 4 above. After the installation of the flooring is completed, floor concrete is poured on the upper part, and special parts are assembled in the necessary order by a series of operations of the crane C, the arm 38 of the work robot, and the gripping mechanism 39. go. When the construction of one floor is completed, as described above, the temporary shed T is raised one floor and the next floor is constructed, and the construction is carried out sequentially to the upper floors up to the predetermined floor. c: Horizontal movement method of temporary shed a. Movement in girder direction In Figures 1, 2, and 12 to 17, the temporary pillar 1 below the crane girder CG is moved to shorten the temporary pillar 1a in street A to 1b, and the assembled permanent structure is completed. Move away from S and lift it to a height where there are no obstructions. Next, as shown in FIGS. 11 and 12, the temporary pillar 1 is moved to a position close to the temporary pillar 1 on street B so that it receives the weight of the temporary shed T. Based on the positional relationship of the pillars, the temporary shed T is moved in the direction of B1 as shown in FIG. 13. Next, as shown in FIG. 14, the temporary pillar 1 on Street C is moved closer to Street D. In FIG. 15, the temporary pillar 1 of Street B is moved to Street C, and the pillar 1 in the middle of Street AB is moved to Street B. In FIG. 16, the pillar 1 in the direction D is moved in the direction B1 and expanded to be in the state 1c. Next, move pillar 1 in the middle of CD street to D street. Furthermore, as shown in FIG. 17, after moving the temporary shed T in the direction of B1, the pillar 1c located in the middle of Street DE is moved to Street E, completing the movement of the entire temporary shed T for one span. This series of operations is repeated to move the entire structure to a predetermined position, and the permanent structure S for that part is constructed. B. Movement between beams. The shaded area in FIG. 18 is an integral structure composed of the roof part of the temporary shed T, the crane shelter H, and the inter-beam direction beam B. The part below this shaded area is composed of the girder direction beam G crane girder CG and the temporary column 1, and is configured to slide along the inter-beam direction beam B in the inter-beam direction.

First, as shown in FIG.
Store it in. 6 types of crane girder CG, temporary pillar 1
, the beam G in the girder direction is moved closer to the beam B in five ways as shown in Figure 19.
Move it by sliding it along. 20 corresponds to before the movement, and FIG. 21 corresponds to FIG. 19 after the movement. Figures 22 and 2
5 is a method of moving the pillar 1 and the temporary shed T, in exactly the same order as in FIGS.
~ E way can be read in 6 to 2 ways.

[0012] This series of operations is repeated to move the entire structure to a predetermined position and construct the main structure S in that part. d: Mechanism explanation of each part function b. Girder direction X movement function of the temporary column In Figures 3 to 7, the drive gear of the drive device 2, which consists of a motor, gears, etc., installed on the sliding part K at the top of the temporary column 1 is fixed under the crane girder CG. It meshes with Rack 3. By starting this drive device, the temporary column 1 can freely move the required distance in the girder direction X along the crane girder CG.

Next, when the temporary pillar 1 stops at a predetermined position, the brake (not shown) shown in FIGS. 6 and 7 is activated by a hydraulic system or an electro-mechanical mechanism to eliminate rattling with the crane girder CG. A pair of brake shoes 4 are pushed in from a direction diagonal to the horizontal, and the lower flange of the crane girder CG is evenly sandwiched from above and below to fix the crane girder CG and the sliding part K of the temporary column 1. In the figure, 5 is a wheel for moving the temporary pillar 1.

[0014] Thus, the temporary pillars 1 are individually moved to the required position when necessary and fixed to the crane girder CG, thereby ensuring the structural safety of the temporary shed T. B. Inter-beam direction Y movement function of the temporary column As is clear from Figure 1, the temporary column 1 is the crane girder C.
It is attached to the lower side of the girder G and can move in the girder direction have to move. At this time, it is confirmed that the crane C has already been moved to the shelter H.

[0015] The temporary shed T has three to six consecutive beams B in the inter-beam direction (FIG. 4) in A to D streets. This inter-beam direction beam B carries all the fixed loads, wind, Ensure safety by bearing temporary loads due to earthquakes, work, etc.

The end of the girder direction beam G is fixed to the upper part of the column head 9 of the temporary column 1, and an inter-beam direction beam B is also fixed to this part.
is penetrated. As shown in Figures 3 and 4, a total of eight wheels 10 are installed on the top of the column head 9, and the wheels 10 sandwich the beam B in the inter-beam direction Y without any gaps, and move freely in the directions of arrows P and P'. is now possible. The eight wheels 10 are important parts that have a safe capacity to withstand all the loads that the temporary shed T receives.

A drive device 11 consisting of a motor, gears, etc. is installed at the top of the column head 9, and the gears of the drive device 11 mesh with a rack 12 attached to the lower end of the beam B in the inter-beam direction. By starting this drive device, the integrated part of the temporary column 1-digit direction It also becomes possible to move the temporary shed T horizontally.

When the movement to the predetermined position is completed, a stopper mechanism (not shown) similar to the brake shoe 4 shown in FIGS. 6 and 7 described above is provided to prevent movement and backlash with the crane girder. A connecting member 18 is provided here to integrate the structure above the small beam 6 and the inter-beam direction beam B. C. Crane evacuation function Crane girder CG', truss 17, gable side truss 1 that can install rails 13 that maintain crane wheel spacing
6. The crane evacuation area H is supported by a series of temporary small beams 6 on the hull rim 14 and the outer wall 15, so that the crane can be evacuated. (See Figure 5) Crane girder CG
and CG' are supported separately on A street and D street in FIG. This prevents the wheels of crane C from derailing from the rail 13. D. Expansion and contraction function of temporary pillar In Figures 8 to 10, temporary pillar 1 has cylinder bodies 19, 20, 2.
1 is fitted in such a way that it can slide in a telescopic tube manner with high precision. A flat plate 22 for supporting the load is provided at the top of each cylinder.
It is fixed with lids 23 and 24.

The column is expanded and contracted by driving the motor 25, which rotates a pair of screw rods 27 through a series of gears 26, which rotates the screw 28 fixed to the flat plate 23.
The cylinders 19 and 20 slide against each other via the flat plates 23 and 24 by the screw rod 27 screwed into the cylinders 27 and move in the drawing direction. Further, when the screw rod 27 is reversely rotated by rotating the motor 25 or by operating the gear group 26, the cylinders 19 and 20 are moved in the pushing direction. In this way, the temporary pillar 1 will exhibit the function of expansion and contraction.

Furthermore, a motor 29, a gear group 30, a screw rod 3
1. Since the screw 32, cylinders 20, 21, and flat plates 22, 23 have the same mechanisms and functions as described above, the required functions can be achieved by appropriately operating the motors 25 and 29 according to various situations. Note that the arm 33 shown in FIG. 8 is an auxiliary support that can be attached or used depending on the support situation of the lower surface of the temporary pillar 1.

[Effects of the Invention] As described above, according to the present invention, a building with a large planar extent is divided into a plurality of sections in the direction between the beams and the direction of the columns, and the structure of one section can be made into an industrial product. The building is constructed using a building assembly device equipped with a work robot for assembling building components, and then the building assembly device is moved to a section adjacent to the constructed section in the beam direction or girder direction to construct the structure in the same adjacent section. As described above, according to the present invention, the buildings of each section can be constructed sequentially while horizontally moving the building assembly device, thereby minimizing the need for temporary equipment; It is possible to reduce temporary construction costs and assembly costs, save labor in specialized jobs, shorten construction period, and reduce construction costs.

[0022] According to the second aspect of the invention, in the building construction apparatus, the temporary pillars have a telescoping function so as to hold the work space in the section, and are movable horizontally. Since the gantry supported at the top is configured to be horizontally movable in both orthogonal directions,
Since the construction device of the present invention is movable in the horizontal direction, it can perform construction on each section divided horizontally in the direction between the beams and in the direction of the girders in the building, thereby minimizing the need for temporary equipment. This can save labor and improve workability.

Furthermore, the work robot is removably mounted on a horizontal crane mounted on a crane girder mounted in one direction at the bottom of the gantry and movable in the same direction and orthogonal directions. , work efficiency is significantly improved. Furthermore, since the shed that covers the gantry is mounted on the top of the gantry so that it can be moved horizontally, the work space is always covered by the shed, so construction can be carried out regardless of the weather, and the construction period can be shortened. It will be done.
