Description

Clamp for a scaffold pipe

The present invention relates to a scaffolding pipe installation clamp is installed on the outer surface of the formwork to reinforce the gap of the formwork is installed to assist the shape of the concrete when the concrete is placed for the construction of the building.

As the prior art of the present invention can be seen the building formwork installation structure using the Republic of Korea Patent Registration 10-0501773 binding and fastening clip. This is because the concrete wall of the building concrete is constructed, a plurality of euroform formwork is in close contact with both sides, the formwork is fixed to the formwork by inserting a binding rod into the steel bar installed horizontally in the contact joint to the formwork. Forming anchor is penetrated inside the concrete wall is formed by the concrete is poured, and each of the female threaded connector, fixing bolts, fastening clips are sequentially coupled to the fastening clip is fixed to the steel rod vertically installed.

By the way, the binding bar and the fastening clip for fastening this steel bar (it is called a scaffold pipe in this invention. A steel bar and a scaffold pipe are the same thing.) Are as follows.

The binding table is formed integrally with the cylindrical part and the c groove part, while the fixing bolt part is fastened to the cylindrical part to fix the steel bar, and the inner side of the cylindrical part is formed to be in close contact with the outside of the steel bar. The groove is narrowly shaped so that it can be inserted.

In addition, the fastening clip has an elliptical shape, both sides are formed to be bent, the bolt hole is formed in the center, while the fastening bolt through the bolt hole is coupled to the female threaded connector, the formwork anchor to the female threaded connector To be combined.

By the way, the above invention and the present technology has a problem that the coupling of the scaffolding pipe is not easy. In the case of the invention cited above, in the case of the binding pipe for installing the scaffolding pipe, a cylindrical portion is formed, and the scaffolding pipe is inserted into the cylindrical portion to induce coupling to a part of the flow path. However, in this technology, if the cylindrical part of the binding rod inserts the scaffolding pipe, the pipe is not free to move, and the installation is also performed by visiting the designated location, rather than using the halfway connection method. The situation is difficult.

Also, in the case of the fastening clip, the female threaded connector is mounted on a part of the euroform, which is bent to both sides, and then a bolt is used to sandwich the scaffolding pipe between the fastening clips. have. In this case, too, the management of parts consisting of three stages is difficult to use in the construction site, and in this case, the person who holds the scaffolding pipe and the fastener have to work separately. Considering the installation method of the site where the scaffold pipe is installed while moving mainly on the scaffold pipe, it has a condition that is unsuitable as a clamp for mounting a scaffold pipe composed of several parts.

The present invention has been made in view of the above-described problems, and its object is to securely install the scaffolding pipe mounting clamps on the outer surface of the euroform to be used as formwork, thereby preventing the leakage of mortar when pouring concrete. It is an object of the present invention to provide a building formwork installation structure for preventing the phenomenon that occurs to the outside by the pressure of mortar.

Therefore, in the present invention, the outer pin is inserted into the Eurofoam connecting hole of the vertically installed Euroform, the scaffold pipe is mounted on the pipe hook connected by the hook connecting pin to the outer pin, and the connecting chain is connected to the seating port which is the connecting pin of the outer pin. After mounting the scaffolding pipe, if the pressing lever is rotated, the center axis is on one side in the shape of an ellipse installed under the pressing lever. It is to provide a clamp for scaffolding pipe installation, characterized in that the compression is fixed.

In addition, the Euroform has a fastener seating hole on a portion of the outer pin in order to closely contact the Euroform and the Euroform, and the Euroform support of the two Euroform is pushed into the inside of the fastener seating hole formed in the U groove form by the crimped scaffolding pipe, It is to provide a clamp for scaffolding pipes, characterized in that to prevent the leakage of the mortar while in close contact with the flow form.

Therefore, using the scaffolding pipe mounting clamp of the present invention,

There is an effect that the installation time of the scaffolding pipe can be shortened while the fasteners are recycled, apart from the method of joining the blanking pipe by inserting iron wire into the euroform connection hole provided on one side of the existing euroform.

In addition, when the scaffold pipe is installed alone, the scaffold pipe is formed in a state in which the scaffold pipe is not crimped by itself first, and after the first installation of the scaffold pipe is completed, the scaffold pipe is firmly fixed to the euroform by using the crimp lever. It is effective to shorten the installation time and labor costs due to the fixed. This is the method of choice because it is difficult to fix the other parts of the scaffolding pipe later because there is no play of the pipe if the one part of the scaffolding pipe is fixed tightly.

 In addition, the part of the outer pin has a fastening hole seating hole, and two euroform euroform supports are pushed into the U-shaped fastener seating hole by the compressed scaffolding pipe. The effect of preventing leakage can also be obtained.

The present invention, a plurality of formwork is aligned in the horizontal and longitudinal direction, the building formwork is supported as a support as a support-in the concrete content of the present technology uses the formwork and the euroform 80 in parallel. When the description is mainly made of a single part, it is referred to as the Euroform 80, and when referring to the whole composed of the Euroform 80, it is referred to as the formwork. The outer pin 60 is inserted between the plurality of flow path connecting holes 81 and the flow path vertical connection hole 81a formed at 84, and the scaffold pipe 70 is inserted into the pipe hook 40 mounted on the outer pin 60. ), And then, by rotating the pressing lever (10) mounted on the pipe hook (40) by pushing the scaffold pipe (70) in the direction of the flow form (80) with the pressing projection (11), the flow path is the support joint support As the foam support 84 is pushed into the fastener seating hole 62 of the outer pin 60, the euro foam support 84 is firmly adhered to each other, thereby providing a rigid fastening structure that prevents leakage of concrete generated from the formwork joint. While providing concrete pouring The combination of the scaffolding pipe 70, the auxiliary coupling supports of the mold is installed is provided a structure for easy fastening.

The formwork formed by combining a plurality of flow path products 80 is pushed to the side by the insertion pressure of the concrete as the concrete is poured, in order to prevent this to form a plurality of scaffolding pipes 70 laterally or longitudinally to the formwork. It is mounted and fixed.

The fixing of the scaffold pipe 70 is mainly made of a thick wire wire (aka half-life), and is inserted into the flow path connecting hole 81 or the flow path vertical connecting hole 81a formed in a plurality of flow paths 80 to bind the scaffold pipe 70. Or use the same straps as the background art. The binding table is formed with the cylindrical portion and the c-groove portion integrally, while the fixing bolt portion is fastened to the cylindrical portion to fix the steel bar, and the inner side of the cylindrical portion is inserted into the scaffolding pipe (7) for installation.

However, the present invention, rather than the binding of the scaffolding pipe 70 by the fastening of the fixed bolt that is a small and separated parts difficult to manage in the construction site, when the pressing lever 10 is rotated in the elliptic form installed under the pressing lever 10 Invented a technology in which the crimping projection 11, which is rotated at the same time as the central axis of the furnace is rotated and the length of the pressing is changed, presses the scaffolding pipe 70 and compresses the scaffolding pipe 70 in the direction of the flow form 80. By quickly and firmly contacting the scaffolding pipe 70 in the direction of the flow path 80 to prevent the lateral flank of the formwork due to the concrete pouring.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view showing the configuration of the present invention as a representative of the present invention.

In general, if you want to make a formwork by connecting the Euroform 80 and the Euroform 80, the external pins that are common in the Euroform connecting hole 81 or the Euroform vertical connector 81a formed in the Euroform support 84, which is the Euroform 80 support. And inserting the outer pin again into the outer pin insertion hole formed in the outer pin to use the method of closely contacting the flow path 80 and the flow path 80.

In addition, when the binding between the euroform 80 and the euroform 80 is completed, the scaffold pipe 70 is bound in a horizontal, vertical, or lattice to secure the formability. However, in the case of the installation clamp of the scaffolding pipe 70 bound to the formwork, it is difficult to induce close contact between the flow path 80 and the flow path 80. Thus, the same method as the background art is being created.

Thus, the case of the scaffold pipe mounting clamp of the present invention was created to conveniently and quickly fasten the scaffold pipe 70 while inducing close contact between the flow path 80 and the flow path 80.

The construction of the scaffolding pipe installation clamp of the present invention is a foreign pin for performing the function of the general external pin for the coupling of the euro-form connecting hole 81 and the euro-form vertical connecting hole (81a) formed in a plurality of vertically and horizontally on the euroform support (84). 60 is configured and a connecting pin mounting hole 63 is formed on one side of the outer pin 60 to hook the pipe hook 40 to the hook connecting pin 50.

In addition, the structure of the outer pin 60 is provided with a seating opening 61 which is a connecting body on which the connecting chain 30 is mounted, on the opposite side of the fastening hole for the Euroform 80 and the Euroform 80 to be closely connected. It has a seating opening 62.

The fastener seating hole 62 is formed in a U-shape intaglio, which is inserted into the euroform connecting hole 81 to which the euroform 80 and the euroform 80 are connected, so that the two euroform connecting holes 81 are formed. As the U-form grooves are inserted into the U-shaped grooves, the Euroform supports 84 are in close contact with each other to prevent the leakage of concrete during the installation of the formwork.

Such a structure is possible because the fastening hole seating hole 62 of the outer pin 60 can forcely insert two combined flow path connecting holes 81 due to the flow path 80. That is, as the crimping lever 10 rotates, the scaffold pipe 70 is in close contact with the flow path 80, and the outer pin 60 is connected to the scaffold pipe 70 by the pipe hook 40 and the connection chain 30. Since the two flow-form connecting holes 81 are pushed into the fastening hole seating hole 62 formed by the U-shaped grooves because of being pulled in the direction of)). The above description is described again in detail with reference to FIG.

A pipe hook 40 is connected to a part of the outer pin 60 so as to surround the shape of the scaffold pipe 70.

The pipe hook 40 is a lever connecting pin 20 is inserted into the connecting pin seating hole 41 formed in the pipe hook 40 where the scaffold pipe 70 and the euroform 80 are formed vertically, and the lever connecting pin ( 20, the pressing lever 10 is provided.

The pressing lever 10 has an elliptical shape installed at the lower portion of the pressing lever 10 so that the pressing shaft 11 is formed in which the central axis is rotated and the length of the pressing is changed at the same time. When rotated, the pressing projection 11 serves to press the scaffolding pipe 70 in the direction of the flow path 80.

In addition, when the crimping protrusion 11 closely adheres the scaffold pipe 70 in the direction of the flow form 80 by the rotation of the crimp lever 10, the pipe hook 40 is connected to the pipe hook 40 to prevent the pipe hook 40 from being opened. The connection chain 30 is inserted into the formed chain connection hole 42, so that it is mounted on the seating port 61, which is the connection body of the outer pin 60.

This is because the scaffold pipe 70 is inserted into the flow path 80 and the pipe hook 40, and prevents the pipe hook 40 from opening when the scaffold pipe 70 is compressed while preventing the scaffold pipe 70 from being separated. The connecting chain 30 was mounted on the seating port 61, which is a connecting chain of the outer pin 60. When the temporary installation of the scaffold pipe 70 is completed in this way, the pressing lever 10 is rotated (pressed in the pipe hook direction) so that the crimping protrusion 11 is firmly adhered to the flow form 80 by the scaffold pipe 70. The formwork is firmly installed while the flow path connecting hole 81 formed in the two flow paths 80 is strongly inserted into the fastening hole seating hole 62 of the pin 60.

Reference is made to FIG. 2 to describe the above technique in more detail.

Inserted, the connecting pin 30 in the state in which the connection chain 30 is seated in the seating port 61, which is the outer pin 60, the connecting chain, the compression projection (11) is rotated, the central axis in the oval-shaped form of the pressing projection 11 ) Rotates about the lever connecting pin 20, the opposite side of the central axis pushes the scaffolding pipe 70 in the flow path 80 direction. Here again, the outer pin 60 is brought into close contact with the scaffold pipe 70 in the direction of the scaffold pipe 70, and thus two euroforms 80, the left euroform 80a and the right eurofoam 80b. In the state in which the outer pin 60 is inserted into the Eurofoam connecting hole 81 formed in the), the two Eurofoam connecting holes 81 are forced into the fastening hole seating holes 62 of the outer pin 60 while being Eurofoam. The result that the 80 and the euro-form 80 is in close contact with each other. Therefore, there is no leakage of concrete even when forming formwork and placing concrete.

As described above, when installing the formwork for concrete placing by connecting the Euroform 80 and the Euroform 80, the Euroform (80) and the Euroform (80) for the close contact and the rigid coupling of the scaffolding pipe 70 The outer pin 60 is inserted into the Euroform connector hole 81 of 80 and the connection chain 30 is mounted on the connection chain seat 61, and then the compression lever 10 is rotated to form the compression lever 10. The crimping protrusion 11 closely presses the scaffolding pipe 70 with the euroform 80 while pressing the fastening hole seating hole 62 of the outer pin 60 to the two euroform connecting holes 81, thereby compressing each other. 80) and the induction of the contact with the foam 80, and strengthened the binding force of the scaffolding pipe (70) in the construction of a safe and solid formwork to achieve a variety of effects simultaneously with a simple construction method and one structure.
