Description

Formwork gap holder {Device for supporting concrete wall form}

The present invention relates to a mold spacing retainer, and more particularly, the convenience of work during the installation or dismantling of the simultaneous formwork that can accurately maintain the distance between the two formwork facing each other so that the concrete mortar is injected and the quality of the concrete structure to be molded Regarding the formwork gap retainer can be expected.

In general, before placing concrete structures such as walls and support columns, both formwork (plywood or steel plates) are disposed to face each other, and a gap maintaining mechanism is used to maintain a constant distance as the thickness of the concrete structure.

In the form similar to the conventional mold spacing mechanism, by tightening the nut fastened to the tie bolts on the outside of both formwork using a tie bolt penetrating the coupling holes formed in both formwork at the same time the worker in the field maintains the distance between both formwork There are formwork gap adjusters that allow the gap to be adjusted.

Forming space maintenance mechanism using tie bolts prevents the problem that the fastening part of the formwork space retaining part is cut off due to the load strength received when concrete is being laid down or cut off by using screw type fasteners. In order to tighten the tie bolts, the entire body of the formwork spacing is formed to reinforce the periphery of the fastening hole.

In addition, as the thickness of the entire formwork gap retainer is thickened to reinforce the periphery of the fastening hole, the price of raw materials is inevitably increased, which causes a price increase for the entire formwork gap retaining tie bolts. When the price of raw materials rises and the shortage of raw materials occurs, the price of raw materials rises further, and the manufacturing cost of the formwork spacing zone is further increased. As a result, the construction site that does not have formwork spacing tie bolts is available. In reality, the problem is that the entire construction work is suspended.

Above all, in order to prevent the failure rate of the structure due to the higher standard of construction and civil construction or the deviation of the workers of the site, the spacing of formwork installed on the site follows the preset position, that is, both formwork is It is only necessary to satisfy the fixed state of the formwork while maintaining the space between them.

The conventional formwork spacing holder 5 is installed at the bottom bottom of the formwork in which concrete is introduced, unlike the above-described tiebolt method, and after the curing of the concrete in the step of removing the formwork panel (1) (2) Removal has the advantage of preventing the formation of grooves in the concrete structure.

However, such a conventional formwork spacing 5 is fixed at the bottom between the formwork panel (1) (2) by the bottom surface and the fixing pin (6) if the operator need to readjust the position of the formwork. If there is, there is a difficulty in separating the fixing pin (6) due to the narrow working space between the two formwork panels (1) (2), and eventually both formwork panels (1) again from the formwork gap holder (5) After removing (2) and forcibly dismantling the fixing pin (6) of the gap retainer (5) there was an inconvenience to be reinstalled again.

In addition, the conventional formwork gap holder 5 is installed between both formwork panels, in order to prevent the formwork panels from being pushed outward in the process of the concrete input and curing in the future is in close contact with the formwork panel (1) (2) Fixing the both ends of the spacer by using a bolt or the like must be performed separately, thereby forming an unnecessary groove in the concrete structure to be formed.

In addition, the conventional formwork gap holder (5) is not removed after curing of the concrete to be integrated with the concrete, the deformation caused by the corrosion of the gap holder made of concrete and heterogeneous (usually iron plate), such as deterioration of the quality of the concrete structure. It became a factor.

Therefore, the present invention is to solve the conventional problems as described above, the object is to provide the convenience of the field worker during the installation work of maintaining the gap of the panel constituting the formwork and the work of separating the formwork after concrete curing The present invention provides a mold spacing holder that can conveniently perform repositioning of the formwork.

In addition, another object of the present invention is the initial position of the panel spaced apart at regular intervals to bear the compression and tensile load of both panels constituting the form even if using a material of a high strength, such as aluminum or synthetic resin, such as conventional steel sheet To provide a formwork gap holder that can firmly adhere to.

In addition, another object of the present invention after the completion of curing of the concrete mortar, the parts of the formwork is exposed around the concrete structure to weaken the rigidity of the concrete or to prevent the closing end to act as an interference member in the future finishing work In providing a holding tool.

In the present invention for achieving the problem as described above and to eliminate the conventional drawbacks in the formwork gap holder for maintaining the fixed gap between the panel and the panel constituting the formwork,

A binding portion into which the panel and the bottom of the panel are fitted respectively;

The first protrusion 112 ′ and the second protrusion 113 ′ in close contact with the bottom surface of the panel 1 and 2, wherein the first protrusion 112 ′ and the second protrusion 113 ′ are in close contact with each other. ) Is formed with the height difference to be stepped on each other easily to insert the bottom of the panel (1) (2). In addition, a rib 115 'is formed on one side of the first protrusion 112' or the second protrusion 113 'which is in close contact with the inner surface or the outer surface of the panel 1,2.

The pair of formwork spacing holder 10 'according to another embodiment of the present invention is connected to the buried body 12, unlike the one embodiment described above to form an integral change in the distance between both panels (1) (2) That is, there is an advantage that can be freely adjusted according to the thickness of the concrete structure.

The detailed configuration and operation of the binding portion 11 'and the fixing portion 13' constituting the pair of spacers 10 'according to another embodiment of the present invention are described in the above-described embodiment. It is omitted as overlapping with (10).

Looking at the installation process of the formwork gap retainer made of the above structure is as follows.

After arranging a plurality of spacers 10 on the floor of the workplace requiring a concrete structure, the fasteners (15: anchor bolts, fixing pins) on the floor through the fastening holes 131 formed in each of the separable fixing parts 13 Drive in and fix it.

Subsequently, the lower ends of the panels 1 and 2 are inserted into and fixed to both the binding parts 11 arranged side by side to install the panel 1 and 2 of the formwork facing each other to maintain a predetermined interval. At this time, by the first and second protrusions 112 and 113 having a height difference with each other and forming a step, the operator does not need careful surroundings when inserting the lower end of the panel 1 and 2 toward the binding unit 11. Without lowering the panel (1) (2) in close contact with the first protrusion (112) protruding upwards first, it is possible to implement a simple insertion into the binding groove (110).

Thus, the panel (1) and the panel (2) according to the present invention are inserted into the binding unit 11, respectively, to form a state placed on the floor surface while maintaining a certain distance from each other, but not shown, but the introduction of concrete mortar For the purpose of closing the front and rear side walls of the formwork, except for the open top of the formwork, separate tie members in the middle or top portion of the formwork to prevent the tops of the panels 1 and 2 from spreading or flowing. Unite (not shown) to finish the formwork.

On the other hand, after the installation of the formwork is completed, in the case where the installation position of the formwork is not changed or the exact point is not installed without removing the panel (1) (2) detachable fixed part (exposed according to the present invention) It is possible to easily change the installation position of the formwork by removing the fasteners (15) that were fastened to the 13).

In this way, the concrete mortar is put into the formwork, and after the curing process for a certain time, the formwork is separated from the concrete structure.

That is, the tie member (not shown), which is bound to the front and rear side walls of the formwork and the middle or upper portion of the panel, is removed, and the final panel 1, 2 is joined to the spacer 11 of the spacer 10 according to the present invention. Lift off from the top). As such, by removing the panel 11 and the insertable coupled panel 1 and 2 without the need for a separate fastening member, various grooves are formed on the surface of the conventional fastening part, and the internal reinforcing bars are oxidized due to the groove. Compared with the conventional concrete structure in which structural problems such as corrosion have occurred, excellent rigidity and surface quality of the cured concrete structure can be obtained.

In addition, after the panel (1) (2) is removed, the fastener (15) bound to the detachable fixing part 13 is removed, and the detachable fixing part 14 exposed to the outside of the concrete structure is folded several times. The binding part 11 and the detachable fixing part 13 connected to the cutting recess 121 are removed from the body 12 integrally embedded in the bottom of the concrete structure. By removing the binding part 11 and the detachable fixing part 13 along the cutout groove 121, the rigidity of the concrete structure may be adversely affected, such as corrosion due to oxidation of fastening members that remain unnecessarily around the concrete structure. It is possible to eliminate the factors, and to keep the surroundings of the concrete structure more clean, which can solve the inconvenience of work by the interference member in the later process, such as finishing the concrete structure.
