The present invention relates to a continuous structure construction formwork having a self-propelled bogie device and a method for constructing a continuous structure using the formwork, the external formwork to move to the formwork for forming the external both sides of the continuous structure; Internal formwork for the formation of the inner surface of the continuous structure; Frame structure of hexahedron, consisting of a formwork consisting of a self-propelled bogie device that can be adjusted in width and height by the length adjustment means, and movable, reinforces the reinforcement to the constructed foundation slab, the inside of the reinforcement While installing the internal formwork, while installing the self-propelled bogie device inside the installed internal formwork, install a plurality of supports between the internal formwork and the self-propelled bogie device, while installing the external formwork to the outside of the reinforcing bar, The internal formwork is connected to the tie to install the formwork, and by constructing a continuous structure by placing and curing concrete on the installed formwork, the formwork by securing the space through the width control and height adjustment by the length adjusting means of the self-propelled bogie device. It is easy to clean, and it is easy to construct a continuous structure.

In general, a continuous structure such as a culvert includes construction of a precast concrete (PC) method in which a unit-size culvert manufactured at the factory is assembled in the field, a formwork is made in the field, and the culvert is reinforced with reinforcement and concrete pouring. There is a field casting method to form.

Recently, a continuous structure is constructed on the site by using a mobile formwork that is easy to assemble and install. First, the mobile formwork is installed on the site, the concrete is poured into the installed formwork, and the concrete placed on the formwork is steam cured. The construction method has been developed to shorten the curing time of the concrete, shorten the air, and facilitate the construction.

For example, Korean Patent Registration No. 0463032 provides a movable steel formwork device which is easy to move by configuring a formwork moving along a rail, and further, in the registered patent, an internal formwork device for the shape of the culvert inside is provided. Further comprising, but the upper slab plate member for forming the inner upper surface of the culvert, the side wall plate member for the inner both sides of the culvert, constitutes the haunch plate material for the haunch side surfaces of both lower edges of the culvert, the upper slab plate member Into the side wall plate member and the haunch plate member, the base in the horizontal direction and the support column in the longitudinal direction are integrated to install a lifting device in the lower part of the base, and both sides of the base constitute expansion and contracting means. Expansion means are provided on both sides of the upper and lower slab plate members in a desired position by the movement of the elevating device, and the side plate by each expansion means It has to be re-released the old and the tooth plate to the desired position.

However, in the case of the above-mentioned patent, since the formwork moves along the rail, additional rails need to be installed while installing the formwork, which is cumbersome for later dismantling, and also, the rail has a vertical load and Since it is responsible for the load of the concrete, it should be determined that the strength is excellent, there was a problem that the installation cost increases.

In addition, in the case of the above-mentioned internal formwork device of the registered patent, since the base and the support pillar is an integrated structure, it is difficult to apply when the size of the culvert is different, since the base and the support pillar are mainly connected by welding, Due to the repeated load and fatigue caused by the construction, there is a fear of cracking of the welded part, and it is difficult to check the crack even if a crack occurs. Therefore, the damage of the formwork is high. Due to the easy maintenance, and with the volume of the base and the support pillar, the expansion and contraction device is configured to protrude in a fixed direction outward with respect to the base and the support pillar, so if the size of the culvert is small, There was a problem that assembly and installation were not easy due to volume.

In addition, since the culvert has a continuous structure, construction must also proceed continuously. In the process of installing the formwork, the formwork is sufficiently coated with demolding oil, so that the formwork can be easily demolded. After the construction is finished, the deformed oil remaining in the formwork must be washed and moved to the next position before the next construction. However, due to the integrated structure, the formwork is difficult to clean the internal formwork device, so it is completely out. After exposing, it has to be washed again, so there is a problem that the air is long.

The construction method of the continuous structure using the external formwork 10, the internal formwork 20, and the self-propelled bogie device 30 will be described in detail with reference to the process diagram of FIG.

First, the earthwork and temporary installation step (S0) is a process of installing a temporary facility that can dig the ground and support the excavated space in order to install the continuous structure, to form a construction space in consideration of the size of the continuous structure to be constructed In the case of continuous structures that are buried, such as culverts, earthworks and temporary installations are required.However, depending on the type of continuous structures, continuous structures that are constructed on flat lands may only be cleaned up and not installed. In this way, it is preferable to form the construction space in the entire section where the continuous structure is installed.

And the basic slab forming step (S1), as shown in Figure 1, constitutes the foundation slab 100 corresponding to the lower slab (bottom slab, the bottom of the continuous structure) of the continuous structure below the constructed construction space. By reinforcing the reinforcing bar, after installing the formwork, the concrete 60 is poured, and cured for a certain time to form the foundation slab 100, the foundation slab is the construction space (continuous structure is installed All sections).

In addition, the reinforcement step (S2), by placing the reinforcing bar (not shown in the figure) to the upper portion of the foundation slab 100 configured above, in consideration of the structure of the continuous structure, required in the position corresponding to the side wall and the upper slab The reinforcement is to be reinforced according to the strength, the reinforcement is configured along the foundation slab (all sections in which the continuous structure is installed).

Next, the formwork installation step (S3) is a step of installing the formwork with the reinforcement of the foundation slab 100 and the configured above, at this time, the outer formwork 10 and the inner formwork 20 is sufficiently coated with the demolding oil In order to facilitate demoulding, the concrete installation method of the formwork will be described below in accordance with the process diagram of FIG. 8 as follows.

First, the self-propelled bogie device positioning process (G1) is to position the self-propelled bogie device 30 into the inner space formed by the upper portion of the foundation slab 100 and the reinforcement bar, as shown in Figure 2, self-propelled bogie device (30) is moved to the wheel 31e, and located inside the mold 20, and then fixed the position by the height adjusting means (31f), actually moving frame 32 and the inner top frame of the self-propelled bogie device Since the 22 are connected to each other, the inner top die 22 of the inner die 20 is located together with the self-propelled bogie device 30 located therewith.

The internal formwork positioning process G2 is a process of placing the internal side formwork 21 of the internal formwork 20 on both sides of the self-propelled trolley 30 and inside the reinforcing bar, and in fact, the self-propelled bogie long-time position process The order of (G1) and the internal formwork position process (G2) may be changed.

And the width adjustment and leveling process (G3), by adjusting the width and height of each length adjusting means and the shelf-type hydraulic device 33 of the installed self-propelled trolley 30, the inner top die 22 to the inner side die (21) While matching the upper end, the self-propelled trolley 30 and the inner formwork 20 to have a proper distance, at this time, by adjusting the distance between the reinforcement reinforcement, so that the reinforcement has an appropriate coating thickness.

On the other hand, in the process of assembling the inner formwork 22 and the inner side formwork 21, the surfaces facing each other are easily inclined to form a combination, and then, the hydraulic cylinder (31d) of the body frame 31 It unfolds and connects to the fixture of the inner side formwork 21, and adjusts the hydraulic cylinder 21e of the inner side formwork 21 to straighten the lower declination surface formwork 21d.

And the support fixture installation process (G4), when the assembly of the internal formwork 20 through the self-propelled trolley 30 is completed, the body frame 31, the moving frame 32 and each fixture (31 ') (32) ′) To support the load by connecting to the support 40, and also to support the side of the body frame 31, and the fixture of the inner side formwork (21) facing it, and the side formwork (21a) ) And the fixtures of the lower deformed surface formwork (21d) to withstand the load and lateral pressure of the concrete to be poured.

Next, the external formwork installation step G5 is a step of installing the external formwork 10, and as shown in FIG. 1, first, the external both ends formwork 12 is seated on the upper surface of the base slab 100. It is installed so as to be in contact with both ends (both ends in the longitudinal direction of the continuous structure) of the installed inner side formwork 21 (the structure blocking both ends) (so that the hole positions for the tie installation can be matched).

And after moving to the wheel (11a) so as to contact the outer side die (11) on both outer sides of the base slab 100 is located in parallel with the inner side die 21, after fixing the position with a height adjusting means (11b) , If the tie 50 is connected through the hole corresponding to the inner side formwork 21, the installation of the formwork is completed, with such an installation, the self-propelled trolley 30 and the inner formwork 20 and the reinforcing bar sequentially Located, the lower part is supported by the foundation slab 100, the circumference is blocked by the external formwork 10, the upper part is configured to open the structure so that the reinforcement visible.

Next, the concrete pouring and curing step (S4), the concrete 60 is poured into the installed formwork, the cover is cured by curing for a predetermined time.

For reference, the curing of the poured concrete may be carried out a curing method that is usually carried out, it may be carried out a variety of accelerated curing methods that can shorten the curing time.

Representative examples of the accelerated curing, there is a steam curing method and a high temperature curing method, the steam curing method, by supplying steam (steam) to the poured concrete, shortening the concrete curing time, further shortening the air of the continuous structure In winter, the construction is possible, and there is a feature that can minimize the occurrence of dry cracks of the poured concrete, when the construction by the steam curing method, the pipe for supplying steam to the self-propelled bogie device 30, Supply steam to cure.

The high temperature curing method, which is another example of accelerated curing, heats the interior of the poured concrete by various solid fuels (briquettes, coal) or the like, or provides hot air to the poured concrete through a hot air blower. As a method of shortening time, by applying a variety of accelerated curing in addition to the steam curing method, high temperature curing method as described above, there is an advantage that can shorten the air.

And the demolding step (S6), as shown in Figures 5 and 6, after the curing of the poured concrete 60, dismantled in the reverse order to install the installed formwork, first, the external formwork 10 After adjusting the height adjusting means (11b), and move to the wheel (11a) and demolding, the outer end die 12 is also dismantled sequentially.

And look at the dismantling method with the inner formwork 20, first, the support frame 40, the body frame 31 and the inner side formwork 21 is installed to connect the body frame 31 and the moving frame (32) After disassembling all the supporting tools, the side mold (21a) and the lower hunting surface formwork (21d), the lower hunting surface formwork (21d) is removed using the hydraulic cylinder (21e). At the same time, the inner upper formwork 22 is separated by the shelf-type hydraulic device 33 of the self-propelled trolley 30, and the inner side formwork 21 is operated by using the hydraulic cylinder 31d of the self-propelled trolley 30. Separating) completes the continuous structure consisting of concrete 60 and rebar.

For reference, the tie 50 connecting the external formwork 10 and the internal formwork 20 is generally removed, leaving a hole for fixing the tie 50, but using the buried tie 50 Since the hole does not occur in the structure, it is preferable to use a buried tie 50, the construction of the connection structure of one unit size is completed when the demoulding of the formwork is finished.

In addition, when the construction of the connection structure of the unit size is completed as described above, by minimizing the size of the self-propelled bogie device 30, through the space secured in the continuous structure, the demolding oil and foreign substances, etc. remaining in the internal formwork 20 Cleaning step (S6) to clean the removal is carried out, in this cleaning step (S6) is more space than the existing construction method is easy to clean and clean, such as removing the demolding oil.

And for the construction of a continuous structure that continues in series, by moving the formwork to a continuous position in the continuous structure of the unit size of the construction, in the formwork installation step (S3) to repeat the demolding step (S5) and the cleaning step (S3) In practice, it is possible to produce connecting structures of the desired length, and the construction of the continuous structure is removed according to its type, and then buried.

The continuous structure as described above may be a concrete structure that is empty and continuous, for example, an upper surface (upper slab), such as a culvert, rainwater, a sewer box, an underground passage box, a dwelling box, a cavity, an electric power outlet, a communication port, and the like. It is possible to construct a continuous structure of a closed structure with a lower surface (base slab) and both sidewalls, as well as to an open continuous structure.When constructing a continuous structure, when placing concrete in the installed formwork, When the concrete is poured to the inner formwork 22 of the inner formwork 20 or less (actually, in the case of an open continuous structure, since it does not form an upper haunch surface, it is preferable to pour the concrete only up to the height of the side formwork of the inner wall formwork). It is possible to construct a continuous structure having an open top structure, for example, a continuous structure such as a water channel, an agricultural water channel, or the like.

As the continuous structure is constructed in this way, since the formwork is fixed by the height adjusting means 11b and 31f while moving by the wheels 11a and 31e, the installation is quick and easy, and the concrete 60 When demolding after curing and curing is easy, demolding is easy. When demolding, the hydraulic cylinders 21e and 31d of the self-propelled trolley 30 and the shelf type hydraulic device 33 are more easily demolded. have.

In addition, since the body frame 31 of the self-propelled bogie device 30 is easy to adjust the width and height adjustment by each length adjusting means, it is easy to install even in a continuous structure of small internal space, self-propelled bogie device 30 Minimizing the size of)), before the continuous structure is constructed, it is easy to clean and clean for removing the demolding oil, and it is easy to repair.

And the hydraulic cylinders 21e and 31d of the wheels 11a and 31e, the height adjusting means 11b and 31f of the outer mold 10 and the inner mold 20, and the self-propelled trolley 30 of the mold. ) And the shelf-type hydraulic device 33, and also the hydraulic cylinder belonging to the length adjusting means of the body frame 31 can be controlled in the control box 200, thereby minimizing the manpower, and the construction is easier to effect have.
