The moving vehicle main pavement brick installation device S is used by being attached to a moving vehicle, and a forklift machine V is applied in this embodiment. That is, as illustrated in FIG. 8, the forklift machine V is arranged on the rear surface side of the brick installation device S for the main pavement, and the fork F thereof is inserted into the insertion opening 54 of the hanging portion 7 of the brick installation device S for the main pavement. And hang and hold.

The construction work of the paving bricks using paving bricks installed device S has the constitution on the paving bricks installed Installations ordination is done as follows.
Hereinafter, the construction procedure will be described.

(1) In the brick installation device S for the main pavement, which is arranged independently, each operating part of the brick installation device S for the main pavement is set to the initial state. That is, by contracting the hydraulic cylinders 19 and 33 of the support plate moving mechanism 3 and the vertical movement mechanism 4, the support plate 2 closes the bottom surface of the brick storage unit 1. Further, the operating hydraulic cylinder 39 of the lateral pushing device 5 is contracted to cause the pushing hydraulic cylinder 38, and the hydraulic cylinder 45 of the clamp device 6 is contracted to release the clamp. In this initial state, the bricks R are placed on the support plate 2 via the door 12, and the bricks R are stored in the brick storage unit 1 in multiple stages.

(2) The brick installation device S for the main pavement is engaged with the fork F of the forklift machine V through the insertion port 54 to be suspended and held, and the installation device S is moved to the laying position to support the support plate 2 The space below is set to a state in which a margin corresponding to the thickness of the brick R is allowed (this is referred to as an initial position).

(3) Hydraulic cylinder 33 of the vertical movement mechanism section 4
Is extended to lower the support plate 2 and the sliding plate 16.
Then, all the bricks R in the brick storage unit 1 are lowered, and then the hydraulic cylinder 45 of the clamp device 6 is extended to lock and hold (clamp) the second-tier brick R from the bottom on the support plate 2. As a result, the bricks R of the second stage and above are pressed and held in the brick storage unit 1, and only the bricks R of the first stage are placed on the support plate 2. The clamp device 6 does not necessarily have to be provided on the rear surface 1b of the brick storage unit 1,
It may be provided on the side surface 1c and pressed and held from the side.

(4) Hydraulic cylinder 1 of support plate moving mechanism 3
9 is extended, the support plate 2 is moved forward, that is, in the laying direction via the connection plate 14, and the brick R is brought into contact with the sliding plate 16 that has been lowered in conjunction with the support plate 2 to pull out the support plate 2. The brick R on the support plate 2 is landed on the ground at the brick laying position. At this time, if there is a gap between the landed brick R and the existing brick surface, the hydraulic cylinder 19 of the support plate moving mechanism unit 3 is contracted so that the rear end surface of the support plate 2 becomes the front end surface of the brick R. The bricks R are brought into contact with each other and the brick R is pressed and moved rearward. After the second-stage brick R is pressed and held on the inner surface of the brick storage unit 1 by the clamp device 6, the support plate 2 is lowered again to separate the first-stage (lowermost) brick and the second-stage brick. Alternatively, the support plate 2 may be pulled out after forming a gap between them.

(5) Hydraulic cylinder 3 for operating the lateral pushing device 5
After extending 9 to position the extrusion hydraulic cylinder 38, the extrusion hydraulic cylinder 38 is extended and the laid brick R is moved. Thereafter, the pushing hydraulic cylinder 38 is contracted, and the operating hydraulic cylinder 39 is contracted to the initial state.

(6) The hydraulic cylinder 33 of the vertical movement mechanism 4 is contracted to raise the support plate 2 and the slide plate 16, and the hydraulic cylinder 19 of the support plate movement mechanism section 3 is contracted to retract the support plate 2. , The support plate 2 is returned to the initial state.
At this time, it is free to contract the hydraulic cylinders 33 and 19 of the vertical movement mechanism 4 and the support plate movement mechanism section 3 simultaneously or individually.

(7) The hydraulic cylinder 45 of the clamp device 6 is contracted, the pressing of the hydraulic cylinder 45 is released, and the brick R of the second stage or more is placed on the support plate 2.

(8) The brick installation device S for the main pavement is moved forward by one section with the movement of the forklift machine V to the next laying position, the process returns to the process (2), and the processes (3) to (7) are repeated thereafter.

As described above, according to the brick installation device S for pavement of this embodiment, since the bricks R are all laid with mechanical force, labor for handling heavy objects is eliminated, and labor saving is achieved. In addition, it is possible to lay a large number of bricks R over at least one row, and it is possible to significantly improve the construction efficiency.

The present invention is not limited to the above-described embodiments, and various design changes can be made within the scope of the basic technical idea of the present invention. That is, the following embodiments are included in the technical scope of the present invention. The capacity of the brick storage part 1 is free and at least 1
It is sufficient to secure two rows of columns. In the support plate moving mechanism unit 3, the guide unit 18 is not limited to this embodiment, and may be any unit that allows the support plate 2 to move horizontally and restrains the vertical movement (vibration). FIG. 9 shows an example thereof. In the figure, reference numeral 60 denotes a rail body fixed to the support plate 2, and a guide groove 60a is formed at the upper end thereof. Reference numeral 61 is an engaging member fixed to the lower surface of the hanging plate 17, and its lower end portion 61a has a guide groove 60a.
It is engaged by allowing only sliding. Rail body 60
The engaging member 61 may be arranged in the reverse order. In the above embodiment, a general forklift machine V is used as a vehicle for movement, but it does not prevent the use of a dedicated vehicle. In the above embodiment, the road pavement is described, but it goes without saying that it can be applied to the bottom construction in a building.
