Description

  The present invention relates to a paving machine for compacting concrete.

  In placing concrete, an operation is usually performed to increase the density of the concrete by applying appropriate vibration to the fresh concrete that has been placed in the mold. This is called “consolidation”. The purpose is to remove unnecessary mixed air, distribute aggregates evenly, and form high-strength concrete.

  As the concrete compaction method described above, in general, a rod-shaped vibration part is inserted into the concrete from the top of the concrete to directly vibrate the concrete, and a vibrator is brought into contact with the formwork from the outside of the formwork. There is a form vibration method that gives indirect vibration. A large special paving machine is required for casting pavement of concrete, fiber mixed concrete and jet (SFRC) concrete.

For the above-described concrete compaction internal vibration system, a rod-like vibrator as mainly found in Patent Document 1 has been used. However, with the increase in RC and steel bridge special concrete pavement in recent years, both the internal vibration method and formwork vibration method are less effective for concrete pavement of thin-layer concrete (concrete thickness 10cm or less).
I couldn't compact enough.

  Furthermore, a large-scale device used for concrete pavement as disclosed in Patent Document 2 has a high manufacturing cost, requires labor for installation, and steel fiber-mixed super fast hard concrete recently used for concrete pavement, etc. In the construction of special concrete, there were many cases where the compaction of the concrete was poor and the effect and durability were halved.

  In order to solve the above-mentioned problem, the applicant has provided a hand-held concrete compacting machine in Patent Document 3 that can reliably compact thin concrete such as pavement at low cost. The compacting machine employs a system in which an air vibrator is attached and placed on a flat vibration frame, and vibration is transmitted vertically downward from the surface of the concrete. High-concrete concrete molding and firm adhesion to the existing substrate were realized. In addition, one or two workers can also perform manual work in the placement work of special concrete and civil engineering concrete, enabling a significant cost reduction without using a large special paving machine.

  However, the compacting machine employs a system in which a single vibrating frame is moved by hand, so there is room for improvement in terms of work efficiency in large-area concrete pavement work. That is, if the machine is made large in order to increase the work efficiency in the construction of a large area, there is a problem that it costs for the transportation of the machine, heavy load, rail facilities, etc., and it is necessary to increase the number of workers. The current situation is that it is difficult to increase the number of workers due to the recent shortage of manpower.

  In order to solve the above-mentioned problems, the present invention enables a work with a small number of people regardless of the construction area, and realizes a significant cost reduction such as the cost of transporting and temporary construction of the machine. It is an object to provide a simple pavement machine with high accuracy.

  In order to solve the above-mentioned problem, a simple pavement machine according to claim 1 includes a first vibrating frame, a second vibrating frame arranged in parallel to the first vibrating frame and on the same horizontal plane, and the first vibrating frame. And a pipe group supporting the second vibration frame, a plurality of air vibrators installed on the first and second vibration frames, respectively, and air for sending air from an air compressor to the air vibrator A hose group.

  The simple pavement machine according to claim 2 is characterized in that a traction tool for moving the simple pavement machine is installed at both ends in the longitudinal direction.

  The simple pavement machine according to claim 3 is characterized in that a vertical position adjuster for adjusting the height of the first and second vibrating frames from the work surface is installed.

  The simple pavement machine according to claim 4, wherein at least one sliding plate that is in sliding contact with the work surface is installed on the bottom surfaces of the first and second vibration frames, and the sliding plate slides on the work surface and the like. The simple paving machine can be easily moved on the work surface.

  The simple pavement machine according to claim 5, wherein the first and second vibration frames have a structure for connecting another vibration frame to one end in the longitudinal direction, and the other vibration frames are connected to each other. The lengths of the first and second vibrating frames can be extended.

  Forming high-strength concrete even when compacting low-pressure concrete by adopting a system in which an air vibrator is attached on a flat vibration frame and vibration is transmitted vertically downward from the concrete surface. Can be firmly attached to the existing substrate. In particular, it is effective for placing concrete mixed with fiber (steel fiber, aramid fiber).

  By using a ski-shaped sliding plate detachably installed on the bottom of the vibration frame and a traction tool that advances the machine, it can be placed while sliding on a reinforcing bar, a steel deck, or a concrete plate. Or a guide rail is not required, and a reduction in work personnel and construction cost is realized.

  The vertical position adjuster receives a signal from the laser level at the light receiver and can be controlled manually or automatically (hydraulic, motor) to obtain high construction accuracy.

  Since the length of the vibration frame can be extended by a simple connection work, it is possible to cope with the size of the placement width, and the work efficiency can be improved and the number of personnel can be reduced.
