Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a structure in which a flat part is interposed between the abutting ends of the dowels that join the formworks to each other, so that the separators can be attached to the formworks at the same time as the formworks are joined to each other. Regarding separators for joint type concrete formwork.

Conventional separators have an integral structure with both ends attached to the formwork, so the formwork must be assembled simultaneously on both sides of the specified concrete pouring surface. The drawback was that it had to be assembled.

The present invention is a joint-type concrete formwork telescopic separator that eliminates the complexity of work caused by simultaneous work, allows the formwork on both sides to be assembled separately, and allows the formwork on both sides to be easily connected. The purpose is to provide

In other words, the present invention provides a flat plate-like locking part at one end of a removably attachable part of the receptacle, which is interposed between the mutually abutting end surfaces of both the recesses of the receptacle that joins the molds to each other. The width between the inner surface of a pair of opposing side walls of a joint formed by forming a continuous part of a U-shaped groove, and a pair of opposing side walls of this U-shaped groove when the joint is fitted into an H-shaped WJ of this continuous part. an intermediate bar having connectors screwed together at both ends, each having a portion having the same width as the intermediate bar;
It is characterized by comprising a pin that penetrates the connector and the connecting portion and connects them detachably.
Along with the work of joining the formwork together, the joint is also combined with the formwork, so not only is there no need for a separate work of joining the formwork and the joint, but the intermediate bar that connects the joints can be attached to the joint. When connecting the connector to the connecting part, it is as simple as inserting the connector into the connecting part from one side and using a pin to prevent it from coming out. Therefore, an external force that separates the connecting part and the connector from each other and moves them away from each other in the longitudinal direction may be applied, but since this external force acts as a shearing force on the pin, even if it is a wooden pin. Even if there is a problem, it strongly resists this external force and firmly maintains the connection between the connecting part and the connector. Therefore, it became possible to powerfully connect the formwork on the opposite side at a predetermined interval during work inside the cylinder.

Further, as in the embodiment section, the connector and the connecting portion can be configured to be freely connected and separated via a plurality of pin through holes provided at appropriate intervals along the longitudinal direction of the separator. This eliminates the need to adjust the spacing between the connectors at both ends of the intermediate bar over a large range, and
Since the joint spacing can be easily adjusted over a desired wide range by adjusting the pitch, the work of adjusting the joint spacing becomes easier.

The implementation of Suekan IJI will be explained below based on the drawings.

Detailed Description of the Invention The present invention provides a method for joining adjacent formworks together by interposing a flat plate-shaped retainer 1: between adjacent abutment surfaces of respective adjacent formworks of opposing formworks. The present invention relates to a joint-type concrete formwork separator that can also be accommodated in the formwork. Conventional separators have an integral structure with mounting parts at both ends for fitting into the formwork, so when assembling the formwork, the separator must be assembled with the opposing formwork partially assembled. Even if you try to install the separator, the length of the separator is longer than the distance between the opposing formworks. We had no choice but to adopt a method of incorporating the following. Furthermore, in this case, the distance between the opposing formworks had to be set and adjusted each time a separator was installed, which impeded construction efficiency. The present invention provides a state in which the opposing formworks on both sides can be assembled separately (1,!it), and the opposing formworks on both sides can be easily connected, and the opposing formworks on both sides are assembled separately. However, it is an object of the present invention to provide a joint-type concrete shrinkage separator for frames that can arbitrarily adjust the distance between opposing formworks.In order to achieve the above object, the following configuration is used.The present invention is interposed between the adjacent abutting surfaces of each adjacent formwork of the opposing formwork, and a cross-sectional A joint formed by forming a continuous portion (2) of approximately U-shaped grooves opening laterally in the longitudinal direction of the separator, and a U-shaped joint formed in the continuous portion (2) of the joint with respect to the opposing formwork. An intermediate bar with connectors fitted into the square grooves screwed onto both ends, the connector and the continuous portion, and a through hole provided in the 117J connector, and a longitudinal direction of the continuous portion. The structure includes pins that pass through holes provided at appropriate intervals in the direction along the direction and connect the two removably.The effects of the present invention are as follows. Since it has a substantially U-shape that opens toward the side force in the horizontal direction, the continuous portions of the joints, which are individually assembled in the opposing formwork,
Above all, the connector can be inserted into the bottom, and since the intermediate bar is shorter than the distance between the opposing formworks, the separator can be attached to the opposing formworks when the opposing formworks are assembled separately. This can be easily arranged.
Moreover, since the connection method for connecting the connector and the connecting portion only requires fitting from the side, the connection method is easy, and a simple strong connection structure such as a pin connection can be formed. Furthermore, the connector and the intermediate bar are screwed together, and the connector and the joint can be finely adjusted and coarsely adjusted as described above, and the opposing formwork is assembled separately, or
The effects of the present invention, in which opposing formworks are assembled step by step, are as follows: When installing a separator between opposing pear frames, there are few restrictions on assembling the formworks, so work can be carried out with high efficiency.
