Description

[Detailed description of the invention] (Industrial application field) This invention relates to a temporary sliding formwork for concrete construction, and is used in side frame construction using a formwork in which a wooden panel face plate is surrounded by a steel outer frame. , relates to a temporary sliding formwork suitable for constructing areas that cannot be covered with a formwork of a predetermined size.

(Prior Art) The present applicant has previously filed an application for a temporary formwork for concrete construction in which a wooden panel face plate is surrounded by a tubular steel formwork (Japanese Utility Model Publication No. 121059/1983).

This formwork connects steel outer frames with specified connecting fittings, and has various advantages such as being lighter than wooden formwork, offering better work performance and higher finishing accuracy. It is something that you have.

On the other hand, concrete formwork that can be extended laterally (Japanese Utility Model Application No. 61-95853) and underwater concrete formwork that can be extended in the height direction (Japanese Patent Application Laid-open No. 60-129361), etc. is proposed.

(Problem that the invention aims to solve) However, when using a formwork that surrounds a wooden panel face plate with a tubular steel formwork, it is necessary to install adjustment panels to fit the space that cannot be covered by the specified size of the formwork. To use it, a wooden formwork made of wooden face plates and crosspieces had to be used as adjustment panels. Therefore, even in a formwork surrounded by a tubular steel formwork, it takes time and effort to form wooden adjustment panels as in the past, and this time and effort has been a hindrance to formwork construction.

On the other hand, concrete formwork that can be extended laterally is especially used as formwork without frame frames attached, and the finished dimensions around such formwork are not very accurate. It's not a thing. Therefore, although such formwork is suitable for construction work with loose standards for finished dimensions of concrete, such as formwork for earthworks at civil engineering construction sites, it is not suitable for construction, for example, of building walls, etc. This type of formwork is unsuitable for construction projects where standards for finished dimensions are strict, even down to the dimensions around the formwork.

In addition, underwater concrete formwork that can be extended in the height direction is a device that adapts the support of the formwork for constructing breakwaters etc. to the unevenness of the seabed. It can be slid freely. In other words, in the underwater concrete method, the formwork that has been preassembled on land on top of the pillars is submerged underwater, and concrete is poured inside this formwork. Therefore, if there is a change in the part where concrete is to be poured, the formwork must be replaced. This is to be changed when assembling on land. Therefore, even if the pillars that support the formwork are made to be able to slide freely, it is not possible to supplement or change the concrete pouring area, and these supplements and changes require a lot of work during assembly work on land. It takes time and effort.

Therefore, this idea was devised to solve the above-mentioned problems.The length of the formwork panel can be adjusted extremely easily, and the formwork panel can be formed using commonly used control panels. To provide a formwork which can be freely adjusted in length and has excellent finishing accuracy.

(Means for solving the problem) In order to achieve the above-mentioned purpose, this invention is based on a temporary formwork in which a tubular outer frame is provided around a wooden face plate, and the formwork is divided at appropriate positions. A formwork main body and a slide body are formed. A reinforcing member extending from the face plate of the main body of the formwork to the slide body, and a slide reinforcing member extending from the slide body to the main body of the formwork and slidably contacting the reinforcing frame are provided. In addition, the main body of the formwork and the sliding body are slidably connected via a slide rod that fits into the divided end of the outer frame, and an adjustment panel is provided between the separated face plates of the main body of the formwork and the sliding body. A removable attachment is a means to solve the problem.

(Function) According to this invention, a temporary formwork consisting of a wooden face plate and a metal tubular outer frame is divided into upper and lower parts: the formwork main body and the sliding body.

The formwork main body and the slide body are fixed and reinforced by the reinforcing frame and the slide reinforcing frame, and also serve as a guide when the slide reinforcing frame slides.

Furthermore, these reinforcing frames and slide reinforcing frames are
They are slidably connected via slide rods inserted into the divided ends of each outer frame.

The face plate adjustment panel is removably attached between the end of the face plate of the main body of the formwork and the face plate of the slide panel that has been slid along the slide rod from the main body of the formwork, extending the overall length of the formwork. urge

(Example) Hereinafter, an example of this invention will be described in detail with reference to the drawings.

In the drawing, reference numeral A indicates a main body of the formwork, and reference numeral B indicates a slide body slidably connected to the main body of the formwork A. These formwork main body A and slide body are formed by dividing a temporary formwork in which a metal tubular outer frame 2 is provided around a wooden face plate 1 into upper and lower halves at appropriate positions. .

That is, the main body A of the formwork is composed of the face plate 1, the outer frame 2, and the reinforcing frame 3, and the metal outer frame 2 is provided on three sides of the face plate 1 except for one side of the outer periphery. This outer frame 2
Reinforcement grooves 2A are provided along the longitudinal direction on the inner and outer surfaces of the outer frame 2, and the cross section of the outer frame 2 has a substantially figure-eight shape. In addition, a separator insertion groove 2B is provided at an appropriate position on the outer surface of the outer frame 2, and the separator is inserted into the hole formed by the separator insertion groove 2B of another mold body A adjacent to this separator insertion groove 2B. It is something that forces you to do something.

The reinforcing frame 3 has a rectangular tube shape and is provided on the surface of the face plate 1 in parallel with the outer frame 2. A rod-shaped connector 4 is slidably provided on the side surface of the reinforcing frame 3, and the tip of the connector 4 protrudes from the reinforcing frame 3 to the outside of the outer frame 2. Insert into the side,
Provided to lock the formwork together.

On the other hand, the slide body B is slidably connected to the formwork main body A via a slide rod 8 that fits into the divided end of the outer frame 2 of the formwork main body A, and is connected to one side of the peripheral edge of the slide face plate 5. Similar to the main body A of the formwork, the three sides excluding the main body A are surrounded by a metal slide outer frame 6 having a tubular shape in a substantially U-shape. In the illustrated example, the slide rod 8 inserted into the divided end of the outer frame 2 of the slide body B is fixed within the outer frame 2, but the formwork main body A
The slide rod 8 inserted between the sides may be fixed within the outer frame 2.

The slide body B also includes a substantially U-shaped slide reinforcing frame 7 extending along the longitudinal direction of the face plate of the formwork.
The slide reinforcing frame 7 is slidably fitted between opposing sides of a pair of reinforcing frames 3 provided parallel to the formwork main body A. The slide reinforcing frame 7 is the slide face plate 5 of the slide body B.
The slide reinforcing frame 7 is extended further downward, so that even when the sliding width of the slide body B is maximized, the slide reinforcing frame 7
The lower end of is formed so as to be in contact with the upper end of the face plate 1. By doing so, a strong supporting force can be obtained even when the sliding width of the sliding body B is increased to maximize the sliding width.

The face plate adjustment panel C is the face plate 1 of the formwork main body A.
It is removably attached between the ends of the slide body B and the face plate 1, which are slid along the slide rods 8 from the formwork main body A, and this face plate adjustment panel C is the same as the formwork main body A, etc. It uses plywood. To fix the face plate adjustment panel C, use the face plate adjustment panel C.
A suitable crosspiece is provided on the back side of the base plate, and this crosspiece is fixed to the adjacent face plate 1. In addition, each outer frame,
It is also possible to fix it to the slide rod 8.

In addition, the drawing shows a formwork that can be divided at the top and bottom of the longitudinal direction to adjust the vertical sliding of the formwork. It is also possible to form a formwork that can be slid in the direction (not shown).

(Effects of the invention) This invention achieves its original purpose by being configured as described above.

That is, in a temporary formwork in which a metal tubular outer frame is provided around a wooden face plate, the formwork is divided at an appropriate position to form a formwork main body and a sliding body,
A reinforcing frame from the formwork-based face plate to the slide body,
By providing a slide reinforcing frame that extends from the slide body to the main body of the formwork and slides freely into contact with this reinforcing frame, when the main body of the formwork and the slide body are used with a distance between them, these reinforcing frames and the slide The reinforcing frame can reinforce the entire formwork.

Therefore, even when an adjustment panel is installed between the main body of the formwork and the slide body, the strength around the formwork with the metal tubular outer frame can be maintained, resulting in improved finishing accuracy. We were able to provide excellent formwork. As a result, it has become possible to perform extremely accurate concrete pouring work compared to conventional formwork that does not have a crosspiece frame attached.

In addition, the main body of the formwork and the sliding body are slidably connected via a slide rod that fits into the divided end of the outer frame, and an adjustment panel is provided between the separated face plates of the main body of the formwork and the sliding body. Since it is removably attached, the overall length of this invented formwork can be freely adjusted by moving the slide body upward along the slide rod.

Furthermore, during this adjustment, the reinforcing frame and the slide reinforcing frame can be used as guides for position adjustment, so that the adjustment is easy, and the form panel can be formed using commonly used control panels. I can do it.

Furthermore, since the adjustment panel is removably attached between the divided face plates of the formwork main body and the slide body, plate materials of the same thickness as the face plates of the formwork main body and the slide body can be attached to the formwork main body and the slide body. It can be easily formed by simply cutting it to match the spacing between. Moreover, since this face plate adjustment panel is surrounded and fixed by the upper and lower face plates and the left and right slide rods, damage to the face plate adjustment panel C during use can be prevented.

In this way, according to this invention, the length of the formwork panel can be adjusted extremely easily, the formwork panel can be formed using commonly used control panels, and it has excellent finishing accuracy. It has various practical effects.
