Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a simple assembly type temporary frame used when pouring concrete, which reduces the amount of material required for each member as much as possible, maintains sufficient strength, and allows the use of factory-produced frames on-site. Easy to assemble and use with 5KL. After pouring and solidification, it can be removed and used repeatedly. The length of the temporary frame can be adjusted according to the length of pouring, and it can also be easily adapted to curved parts. The details of its implementation are as follows with reference to the drawings.

Reference numeral 1 denotes a spacer block, which consists of a main body 2 (made of concrete) and a base plate 4 in which legs 3 are embedded.

As usual, this block 1 is installed on leveling mortar.

A receiving groove 6 is formed by vertically projecting a pair of parallel blades 5 from the upper surface of the base plate 4.

These receiving grooves are buried in the foundation concrete so as to face the outside, and are installed at appropriate intervals on the construction line.

Reference numeral 7 denotes a stud with engagement wings 9 protruding along the longitudinal direction at right angles to both sides of the belly plate 8, and in actual case, the lower end engages with the receiving groove 6 of the block 1 to form a rail.

A mold member 10 has a mold surface 11 on one side, and has reinforcing parts 13 and 14 at the upper and lower edges of the back surface 12.

The lower reinforcing part 14 is fitted into the receiving groove 6 of the block 1, and the mold surfaces 11 are opposed to each other.

The upper and lower reinforcing parts 13 and 14 are composed of a collar 15.16 molded integrally with the mold surface 11 and a retainer 17.18 that connects the end of the collar to the back surface 12. Compatible with

One end surface of the belly plate 8 of the stud 7 faces the same vertical plane as the mold surface 11 of the adjacent mold member 10 to prevent the formation of joints.

Grooves 19.20, 21 and 22 are bored in the flanges 15.16 and the stays 17.18 of the formwork part 10, which engage with the engagement wings 9 of the studs 7.

Due to the engagement of these grooves 19 to 22 with the engagement wings 9, the ends of the formwork member 10 are reinforced via the studs 7, and the mold surface of the member 10 is curved outward on a vertical plane due to the concrete filling pressure. It is also possible to sequentially connect the formwork members 10 to each other through the studs so as to have the required total length.

If the axial length of the formwork member 10 is limited, it may not be suitable depending on the construction site.

The adjustment member 23 is used for such size adjustment.

This member has a height that approximately matches the height of the formwork member 10, and is provided with a holding portion 24 on the upper rear surface thereof to be held onto the upper collar 15 of the formwork member 10.

The retaining member 25 is used to maintain a constant interval between opposing mold surfaces, and has a locking groove 27 formed by a pair of parallel wing pieces 26 on the lower surface of both ends, and an anchor bolt 28 in the middle part. A positioning hole 29 is bored.

This retaining member 25 is normally fitted into the upper flange 15 of the opposing formwork member 10 with a groove 27, but when the retaining member 25 is retained by the adjustment member 23, this groove is provided at the position where it fits into the holding part 24. 27 are prepared.

Furthermore, if the stud 7 is to be held in place, a groove 30 that engages with the belly plate 8 of the stud 7 is bored, even in the case of the above-mentioned sidewall.

31 is an inner corner member and is used when there is a curved part on the construction line.

This member 31 includes a base plate part 32 that covers the end faces of the formwork members 10 that protrude at an angle to each other and abut against each other, and a locking wing 33 that protrudes in the same direction from the core part.

These locking wings are attached to the flanges 15 and 16 of the formwork member 10 and the retainers 1.
It occupies a position where it engages with grooves 19, 20, 21 and 22 bored in 7.18.

In the drawing, reference numeral 14 indicates a water system indicator provided on the central upper surface of the base plate 4, 42 indicates a reinforcing piece provided at right angles to the outwardly extending end surface of the belly plate 6 of the stud 7, and 43 indicates a back surface of the formwork member 10. A reinforcing rib 44 is provided in the upper collar 15 of the member 10 in order to insert the stay 45 therethrough, and a through hole 46 is provided in the upper part of the member 10.
4T is a through hole drilled in the retaining member 25 for fixing the stay 45 to the formwork member 10, and 4T is a groove bored in the reinforcing rib 43 to engage with the locking wing 35.

In the temporary frame shown in the figure, blocks 1 are installed on the leveling mortar on the foundation concrete at appropriate intervals along the construction line, leveled by indicators 41, and the mortar is allowed to solidify.

When the mortar hardens, the lower flange 16 of the formwork member 10 is fitted into the receiving groove 6 of the base plate 4 of the adjacent block 1 to establish the member 10, and the mold surfaces 11 are made to face each other.

When connecting formwork members 1o one after another, stop the longitudinal ends of the members 10 at about half the width of the base plate 4, stand the studs 7 on the grooves 6, push them to the side, and insert the wings 9 of the members 10. Groove 19.2
0.21 and 22.

The end of another formwork part 1o is then set up on the groove 6 of this bed plate 4 and pushed in the direction of the stud 7 into its groove 19.
．． 20, 21 and 22 are engaged with the opposite wing 9.

At this time, the connecting end portion of the formwork member 10 is reinforced by the stud 7, and the mold surface 11 is prevented from curving outward on the vertical plane.

If you connect the following in the same way, you can create as many long frames as you like.

In addition, if the formwork member 10 is configured to a standard length and does not suit the construction site, the adjustment member 23 is used and the holding portion 24
The frame may be passed between the flanges 15 at the upper ends of adjacent formwork members 10.

In this case, the lower end of the adjusting member 23 is free, but if concrete is filled between the mold surfaces 11, it will be pressed against the mold surface 11 by the pressure.

If there is a possibility that the distance between the mold surfaces 11 will be widened by the filling material, a retaining member 25 is installed.

For example, if the groove 27 is fitted into the collar 15 at the upper end of one mold surface member 10, and the opposite mold surface member is similarly fitted, the member 1
0 is stable and the interval between them does not change.

Furthermore, if there is a curved part on the construction line, the inner corner member 31 is applied to the butted part of the formwork members 10, which will be the inner corner.

Generally, this curved angle is 900, so one member 1
The end face of the member 10 is in a state where it abuts against the back end of the other member 10.

Therefore, the base plate portion 32 of the inner corner member 31 is attached to each member 10.
The blade 33 is inserted into the grooves 19, 20, 21 and 2
2.

This prevents the filling material from leaking out along the back surface 12 of the formwork member 10.

In the case of an outer corner, the end face of one formwork member is covered by the mold face 11 of the other formwork member with which it abuts, so there is no need for such a member, and the use of the stay 45 and retaining member 25 is sufficient. It is.

The spaces between the mold surfaces 11 of the temporary frame thus constructed are filled with a filling material, and once the filling material has solidified, the blocks 1 are removed, leaving only the blocks 1, ready for the next use.

According to the present invention, with the above-described structure, other members can be used repeatedly by simply burying the block, and the amount of material used for the formwork members is small, resulting in improved strength. It has various features, such as being sufficient for long construction sites and sites of indefinite length, and can be used without any problems even if there are corners.
