Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a barricade for construction sites (commonly known as A barricade) in which the upper ends of the left and right leg frames that form an inverted V shape are connected by an upper frame pipe, and the lower parts of the front leg rods of the left and right leg frames are connected by connecting rods.
This relates to a connector used to connect adjacent barricades (called "type barricades") in a row of barricades installed in series with connecting pipes.

(Prior Art) Conventionally, in order to connect the above-mentioned barricade rows with a connecting pipe, the pipe is placed between adjacent barricades, and corresponding points on either side of the front and rear leg rods are connected with wire (grid wire). ) is used to tie and secure.

(Problem that the invention attempts to solve) However, the above-mentioned fixing method requires a lot of effort and time to bind and fix the connecting pipes to the barricade with wire, and the fixed state varies, making it unstable and subject to external forces. There is a risk of injury or damage to clothing by touching the tips of the tied wires, and it is troublesome to remove the wires when the barricade is not in use. There were problems such as being extremely uneconomical because it was thrown away without being used.

(Means for Solving the Problems) The present invention solves the above-mentioned problems, and consists of bending an elastic wire of an appropriate diameter to form a vertically long rectangular frame, and barricading both sides of the frame rods in the longitudinal direction. A leg frame rod holding frame formed to form a concave rod portion into which the leg rod is inserted, and an elastic wire rod having approximately the same diameter and appropriate length as the leg frame rod holding frame,
The center portion is a leg rod engaging frame rod portion, and both sides thereof are bent at right angles in the same direction to form left and right side frame rod portions, and the intermediate portions of the left and right side frame rod portions are formed in the same direction. The leg of the leg frame rod holding frame is formed by a pipe holding frame body which is curved in a semi-circular arc shape to form a pipe holding rod portion, and the tip portions of which are formed to form hanging hook portions which are respectively curved outward in an arc shape. The leg rods of the barricade in the rod-fitting concave rod portion are fitted into contact,
engaging the leg rod engaging frame rod portion of the pipe holding frame body with the leg rod to encircle the connecting pipe with the pipe holding rod portion;
The connecting pipes are fixed to the barricade by latching the hooks with strong pressure to the rods on both sides in the longitudinal direction of the leg frame rod holding frame, and the hooks can be removed from the leg frame rod holding frame as appropriate when not in use. The barricade is L
Either a shaped leg rod or a round pipe leg rod can be used, and the present invention will be described in detail below with reference to embodiments shown in the drawings.

(a) Configuration From Fig. 1, we can see that the inner width a of the elastic wire rod made of steel wire or the like of appropriate diameter is the leg rod 11 (the example is L Longitudinal side frame rod part 2 of a frame body 1 formed into a vertically elongated rectangular shape with one short side bent so that both ends overlap, with a width a slightly wider than the rod width a' of (showing the case of a shaped leg rod) , 2 are bent at substantially right angles in the same direction to form concave rod portions 3, 3 into which the leg rods are inserted.
form.

From FIG. 2, an elastic wire made of steel wire or the like having approximately the same diameter and appropriate length as the leg frame rod holding frame A is used, with the central part serving as the leg rod engaging frame rod part 4, and both sides of the elastic wire material being arranged at right angles in the same direction. The side frame rod portions 2, 2 of the leg frame rod holding frame A are bent.
The left and right side frame rod portions 5, 5 are formed in a shape that is parallel to each other and separated by a width a and an interval b that is approximately the same as the width a, and the intermediate portions of the left and right side frame rod portions 5, 5 are separated from each other by the left and right side frame rods. The pipe holding rod parts 6, 6 are curved in a semicircular arc shape in a direction parallel to each of the parts 5, 5 (U-turn direction), and each tip part is curved outward with a curvature larger than the diameter of the wire rod used. A construction site of the present invention is formed by forming a pipe holding frame B with hook portions 7, 7 curved in a semicircular arc shape toward the direction, and a combination of the pipe holding frame B and the leg frame rod holding frame A described above. This constitutes the connector C of the barricade.

(effect) Next, the present invention will be explained based on the state in which it is used.

Figure 3 shows a commonly used barricade for construction sites, with leg rods 11, 11 and 11', 11' made of belt-shaped steel plates bent into an L-shaped cross section, on one side of each with the groove sides facing each other. The ends are fixedly or rotatably connected to form inverted V-shaped left and right leg frames 12, 12', and the left and right leg frames 12, 12' are placed side by side with their groove sides facing each other with an appropriate distance between them. The upper ends are connected by an upper frame pipe 13, and the lower parts of the front leg rods 11, 11' and the rear leg rods 11, 11' of the left and right leg frames 12, 12' are connected by connecting rods 14, 14. At the same time, the lower portions between the front and rear leg rods 11, 11 and 11', 11' of the left and right leg frames 12, 12' are connected by a single rod or foldable connecting rods 15, 15'. A barricade G is constructed.

In addition, when the connecting pipe P is removed from the barricade G, it is easily done by removing the hooks 7, 7 of the pipe holding frame B from the side frame rods 2, 2 of the leg frame rod holding frame A. Tool C can be used repeatedly.

(Effects) The present invention has advantages such as being simple in structure and easy to handle, and being extremely economical because it can be used repeatedly.

In addition, with this invention, the connecting pipe can be securely fixed to the barricade, and the pipe acts as a weight, so when multiple barricades are connected and installed, the barricade can be easily fixed due to external forces such as vibration, contact, and wind pressure. This has excellent practical effects such as there is less risk of the barricades falling over or shifting their installation positions, and the connecting pipes allow the barricades to be arranged in an orderly manner.
