JPH0640645Y2 - Formwork joint for road pavement partition - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention divides into a paved portion and an unpaved portion in a paving work on a wide road surface, and joins a partition member along the dividing line. It relates to a formwork joint for partitioning road pavement.

[Conventional technology]

Conventionally, there has been no proposal of this kind of joint, but on the road surface that is generally done in the case of road paving, it is temporarily divided into a paved part and an unpaved part, and the boundary line is drawn, and multiple lines are drawn along the line. We are laying square timber continuously to prevent the asphalt from leaking, and perform road pavement work.

[Problems to be solved by the device]

As described in the prior art, if square timbers are arranged at the boundaries between road paved portions and non-paved portions, as a partition, the timbers will be misaligned and will stick out to the outside of the asphalt, and the area of the construction surface will differ. There is a problem that it causes.

Therefore, the present invention has been made in view of the problems of the prior art, and the purpose thereof is to make a connecting angle bar having a partitioning function in the case of asphalt pavement on a road surface linearly or curved. Even if it is arbitrarily placed on the road surface, the connecting part can be securely fixed without falling off, and the angle of the timber can be arbitrarily changed by using the joint as a fulcrum to easily perform road pavement work within the required range. It is intended to provide formwork joints for road paving partitions.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the formwork joint for road pavement partition in the present invention is trapezoidal when viewed from above, and a pair of openings having both ends of the receiving piece attached to the outer edge of the bottom surface of the metal plate having a cross section has a pair of openings. A pair of joints is formed, and the outer surface of the inner end corners of each upper side of the joints formed on the slanted sides of the inner ends of the joints is hinged to form the joints so that the joints can be opened and closed. One end of the chain is attached to the mounting metal fitting on the upper side surface, and the fastening metal fitting is attached to the other end and inserted into the gap between the joint and the square bar so that the square bar does not come off from the joint.

[Action]

The joint is used for paving construction of asphalt or concrete such as road surface, laying square timbers inserted and fixed at both ends of the joint along the white line or measuring scale to mark the boundary between the paved portion and the unpaved portion, Lay the timber in a straight line or curved line using the joint as a fulcrum.

Then, the asphalt is paved on the pavement with the square timbers connected by the joint as the boundary, and the roller is rolled on the upper surface of the asphalt to harden it.

When laying the timber in a straight line, the joint shown in FIG. 1 can be used, but it is preferable to use the joint shown in FIG.

〔Example〕

 Examples will be described with reference to the drawings.

In FIGS. 1 to 5, the joints (1a) (1b) made of a metal plate having a cross-section have a trapezoidal shape when individually viewed from a plane,
At the outer edge of the bottom surface, attach both ends of the receiving pieces (2a) (2b) to the joint (1
a) (1b) is fixed to the inner surfaces of the upper side surface (a) and the lower side surface (b) to form openings (3a) (3b), and the joint (1a) is formed.
The inner end of (1b) is formed on the slanted sides (4a) (4b). Then, the corners of the left and right upper side surfaces (a) and (a) of the slanted edges (4a) (4b) are butted, and the outer surface is hinged (5) so as to be openable and closable along the butting points. .

In addition, the joint (1a)
Chain (7a) (7b) on the mounting bracket (6a) (6b) on the side of (1b)
Attach the base end to the other end, fix the fastening metal fittings (8a) and (8b) to the other end, and insert it into the gap between the joint and the square bar (9).
To fix. (10) is a measuring scale.

FIG. 6 shows another embodiment, which is rectangular in plan view and has a cross-section metal joint (15) formed on the side surface of the joint (15) with chains (11a) (11b). Connect one end to the mounting brackets (12a) (12b) and the other end to the clamping brackets (13a) (1
3b) is attached and the squares (14a) (14b) are inserted from both ends of the joint (15), and fixed in the gap between the joint (15) and the squares (14a) (14b).

[Effect of device]

Since the present invention is configured as described above, it has the following effects.

In the asphalt pavement on a wide road surface, the end of the timber can be inserted and fixed in the opening of the joint at the boundary between the paved portion and the unpaved portion, so the timber movement moves together with the weight of the joint. Asphalt pavement parts are reliably separated and there is no risk of protruding to the outside, making it possible to pave a uniform asphalt road surface easily, and without any additional effort.

Further, since the joint is hinged so that it can be opened and closed, it is easy to change the angle of the lumber using the joint as a base point to arbitrarily set the pavement angle.

In addition, since the predetermined timbers are sequentially connected according to the number of joints, there is a practical benefit that the construction section of the pavement work can be divided into long and short sections or wide and narrow sections.

It is suitable for use in concrete pavement.
