Description

Formwork Spacing Device {A CONCRETE FORM SPACER}

The present invention relates to a formwork, and more particularly to a formwork spacing device that allows easy and simple installation of the spacing between formwork.

In general, the formwork is a structure temporarily installed to make the concrete structure into a predetermined shape and dimensions.

In other words, the concrete pillars, floors, walls, etc. are squeezed to form a frame, and then the concrete is poured, solidified, and the formwork is removed to form the pillars, floors, and walls.

Since the conventional formwork is manufactured in the form of wooden boards having a certain shape and dimensions, when placing the wooden board formwork on both sides and connecting several formwork as well as the building and road construction and dam construction, Each formwork is directly coupled to a fastening member, such as a nail or bolt, or put the splints made of other wood, and then combine the fastening members.

Then, the concrete is poured between each of the formwork installed on both sides to harden, and after a certain time elapses, the form, pillar, floor, wall, etc. of the building are removed.

At this time, in order to maintain a constant thickness of the concrete pillars, floors, walls, etc. to be formed, it is necessary to maintain a constant distance between the formwork in which the concrete is poured, the wooden pole having a predetermined length between each formwork Then, the gap between each formwork is kept constant as both sides of the wooden table are coupled to each formwork.

However, since the formwork is made of wood, the wood formwork decays after a long time, thereby reducing the number of times the formwork is reused.

In addition, it is not easy to combine the installation of the wooden bar having a certain length to maintain the spacing between the formwork, and not easy to combine the spacing and the work time and manpower is consumed as well to cut the wooden stand to a certain length Only a skilled worker can do so, there is a problem that the efficiency of the work is lowered.

Thus, in order to solve the above problems, as shown in Figures 1 and 2 was produced a mold spacing device, having a box shape formwork 1 having one side and open with a certain shape and dimensions, In the center of the formwork 1, a fastening hole 5 having a predetermined size is formed, and the material of the formwork 1 is formed of a metal material which can be semi-permanently reused through several times while increasing the strength.

The contact member 3 in contact with one surface of the formwork 1 is located, and the fastening portion 6 in which the female thread is formed is fixedly coupled to the contact member 3. Between the close contact members 3 are screwed to the fastening portion 6 of each close contact member 3, the interval maintaining bolts (2) having a thread formed on both outer periphery is fastened so as to maintain the spacing of each formwork (1) have.

One side of the fastening part 6 of the close contact member 3 is fastened to the gap retaining bolt (2) is formed on the outer periphery, each of the gap retaining bolt (2) is in close contact with the formwork (3) ), The nuts 7 are fastened respectively.

Conventional formwork spacing device of this configuration is positioned between the formwork 1, the spacing holding bolts 2 are in close contact with the contact member 3 on both sides in a state in which the formwork 1 is placed opposite each other.

That is, both sides of the space maintaining bolts 2 are fastened to the fastening portions 6 coupled to the respective contact members 3, respectively. At this time, the space maintaining bolts 2 are rotated as the respective contact members 3 rotate. Each contact member 3 is reciprocated.

As such, since the space maintaining bolts 2 to which each of the contact members 3 are coupled are positioned between the molds 1, the fastening part 6 of the contact member 3 and the center portion of the formwork 1 are formed. The fastening holes 5 coincide.

When the fastening part 6 and the fastening hole 5 coincide with each other, the fastening bolt 4 is inserted into the fastening hole 6 from the outside of the formwork 1, and then the fastening part 4 is inserted into the fastening part ( 6) After fastening the nut (7) to the fixing bolt (4), the space maintaining bolt (2) to which the close contact member 3 is coupled is fixed between the die (1).

As described above, by rotating the close contact member (3) fastened to both sides of the spacing holding bolt (2) to maintain the spacing between each formwork (1) at a desired spacing and then the fixing bolt (4) and the nut (7) The gap between the formwork 1 is kept constant as the space maintaining bolt 2 is fixedly coupled between the formwork 1.

Then, after the concrete is poured between the molds 1 in a state in which the spacing is maintained, if the poured concrete is hardened after a predetermined time, the nuts 7 are loosened, and then the fastening of each contact member 3 is performed. When the fixing bolt 4 is removed from the unit 6 and the formwork 1 is removed, the pillars, floors, walls, etc. of the building are formed by the poured and hardened concrete.

At this time, since one surface of each of the contact members 3 appears on the outside such as a pillar, a floor, and a wall, cement and concrete are applied to one surface of each of the contact members 3.

However, this conventional formwork spacing device is coupled to the components used to maintain the spacing between the formwork in a manner that is screwed together, so that the work time and manpower for joining the parts is generated a lot of work efficiency There was a problem of deterioration.

In addition, as the thread is formed on each part, that is, the thread is formed inside the fastening portion of the contact member, and the thread is formed on the outer circumferential surface of the gap retaining bolt and the fixing bolt. There was also a problem that takes a long time to produce.

In addition, since the mold spacing device is installed at the center of the formwork, the outer peripheral surface of the formwork may be distorted, and thus there is a problem in that the spacing between the formwork is not kept constant.

The present invention has been made to solve the above-mentioned conventional problems, by changing the shape and structure of the parts to maintain the gap between the formwork and the combination of each of the components to be combined in a fitting fixing method between the respective parts Of course, the coupling is made smoothly, and the purpose is to easily and easily install the gap between the formwork.
