RU2453466C1 - Raft section - Google Patents

Abstract

FIELD: wood working industry.

SUBSTANCE: raft section comprises packets of round timber covered with flexible ties, separate round timber placed between packets of round timber and in parallel to packets of round timber, rigid ties made of round timber with length equal to width of a raft section, and having holes at the ends, flexible ties covering packets of round timber and separate round timber. Flexible joints that cover packets of round timber are connected with rigid ties arranged along the bottom of the raft section.

EFFECT: simplified design and also reduced labour intensiveness and energy intensity of raft section manufacturing and disassembly.

Description

The invention relates to an alloy of wood, namely to raft units.

A raft unit is known that contains individual round timber that is laid between packages of round timber and parallel to packages of round timber. Round timber packages are covered by flexible links. Separate round timber and round timber packages are connected by rigid and flexible connections. Rigid ties are made of round timber with a length equal to the width of the raft unit, and have holes at the ends, and are stacked on top of round timber packages and on separate round timber. Flexible ties cover round timber packages and individual round timber and are connected to rigid ties by chain extensions passed through holes located at the ends of the rigid ties. Rigid and flexible connections are interconnected by vertical screeds, dividing individual round timber into equal pack volumes (see US Pat. RF No. 2177436, M. cl. B63B 35/62, 03/13/2000).

The disadvantages of this raft unit are the complexity of the design, high complexity and energy consumption of manufacture and disassembly, low capacity.

The task to which the invention is directed is to simplify the design, reduce the complexity and energy consumption of the manufacture and disassembly of the raft unit, and increase the capacity.

To solve this problem, in a raft unit containing round timber packages covered by flexible ties, separate round timber located between round timber packages and parallel to round timber packages, rigid ties made of round timber with a length equal to the width of the raft unit and having openings on ends, flexible ties covering round timber packages and individual round timber, according to the invention flexible ties covering round timber packages rials connected with rigid bonds located along the bottom of the raft unit.

The combination of flexible ties covering round timber packages with rigid ties located along the bottom of the raft unit ensures the stability of round timber packages during assembly and disassembly of the raft unit when there are no flexible ties covering round timber packages and separate round timber, which allows grabs to be laid when assembly and remove during dismantling of individual round timber placed between packages of round timber. Thus, vertical screeds connecting rigid and flexible bonds and dividing individual round timber into bundles of equal volume are excluded from the design of the raft unit, and therefore, the raft unit design is simplified and the labor and labor costs of manufacturing and disassembling the raft unit are reduced. In the proposed rafting unit, individual round timber can be placed above the packages of round timber, that is, stacked with a slide, which increases the capacity of the raft unit.

Figure 1 shows a raft unit, side view; figure 2 is the same front view.

A raft unit contains round timber packages 1 covered by flexible ties 2, separate round timber 3 placed between the round timber packages 1 and parallel to them, rigid ties 4, flexible ties 5, covering round timber bundles 1 and individual round timber 3. Rigid ties 4 have holes at the ends 6. Flexible connections 2, covering round timber packages 1, are provided at the ends with loops 7 and chain extensions 8 with lever locks 9.

Assembly of a raft unit can be carried out both onshore and on water. When assembling, tight ties 4 are laid on the site and loop loops 7 of flexible ties 2 are put on them, loops 7 are placed at distances from the ends of rigid ties 4 equal to the width of round timber packages 1. Lay round timber packages 1 and wrap them with flexible ties 2. Thread through chain set-ups 8 into the holes 6 of the rigid links 4, select the slack of the chain-links 8 and close the lever locks 9 behind the links of the main branches of the chain-links 8. After that, you can continue assembling the raft unit on the shore or lower the tight links 4 with lennymi thereto flexible links 2 packets round timber 1 for water.

When assembling on the shore or on the water, individual round timber 3 is stacked between packages of round timber 1, after which the packages of round timber 1 and individual round timber 3 are pulled together with flexible ties 5.

Dismantling a raft unit can be done both on the shore and on the water. When disassembling, the flexible connections 5 are released and individual round timber 3 is selected. The lever locks 9 are opened and the chain extensions 8 are removed from the holes 6 at the ends of the rigid connections 4. The packages of round timber 1 are removed, after which the flexible connections 2 are removed.

Packages of round timber 1 can be used as a sub-melting, using increased buoyancy timber for their formation.

The proposed raft unit provides for work on rafts and rafts of float with low labor and energy costs, which will improve the efficiency of wood alloy.

Claims (1)
