Description

[Detailed Description of the Invention] I/'i, Regarding the concrete slab raising construction method, the construction was extremely simple, and it became necessary to adjust the floor height on the same floor, especially due to the design. We are trying to provide a suitable construction method for the construction of bulkheads such as.

Conventionally, in raising construction where the floor height is adjusted by θM on the same floor, concrete is poured according to the desired floor height. Since the weight of the Raise 111S becomes too large, light embedding materials such as foamed polystyrene moldings and cardboard boxes are embedded in the Raise 111S to reduce the amount of concrete and reduce the overall weight of the Raise 111S. However, it is troublesome and inefficient to securely fix the embedded material together with the raising of the concrete floor board, and the metal height is also high when multiple tiers of embedded material are stacked. However, there were drawbacks such as a lack of overall stability. For this reason, there has been a demand for the development of a construction method that can simply and reliably fix the embedded material in accordance with the height of the elevation.

Therefore, in order to satisfy the above requirements, this Hatsu Ejj is trying to provide a concrete slab raising construction method that is extremely simple and much more efficient than conventional construction. An embedding material made of solid matter is placed on a concrete floor plate on which a locking member has been directly erected in advance, a holding member is placed on the embedding material, and the holding member is connected to the locking member. After fixing the embedded material, concrete is poured onto the concrete floor plate.

Referring to the figure, (1) is a suspension member erected at appropriate intervals on the concrete floor plate (2). Seat part 0 to prevent falling against floorboard (2)
1) (see especially Figure 2), and the seat [111
The lower part of is embedded and fixed in the concrete floor plate (2). The locking member (1) F'i is inserted into the concrete before the concrete for the concrete floor plate (2) hardens and is fixed by assimilation of the concrete. This is to keep the retaining member stable so that it does not fall over until the concrete hardens.

Then, on the concrete floor plate (2) on which the above-mentioned special locking member (1) is erected, a light circumferential object such as a synthetic tree 1j is placed.
An embedding material (3) made of rubber foam, preferably polystyrene foam, is placed on top. This 1 year, the embedded material (8) is locked tj
Place it between the rows of Li material (1). The above-mentioned embedding material (3) may be either a solid body or a hollow body, but a split type that can be stacked in multiple stages is most convenient in the city because the height can be freely selected.

A person presses the rod-shaped holding member (4) onto the resting member (1).
At the same time, the holding member (4) is directly connected to the locking member (1) by welding or Vi binding at the intersection, and the embedded material (3) is attached to the concrete floor plate ( 2) Fix it on top (see Figure 3). And appropriate reinforcement (not shown)
After that, if concrete (C) for floor temperature adjustment is placed on the concrete floor plate (2), a raised concrete slag (8) can be formed (see Fig. 4).

The figure in the figure shows the formwork for pouring concrete.

In addition, the retaining member (1) that is erected in advance on the concrete floor Ut (2) K is a member whose lower end, which is embedded in the concrete floor plate (2), is curved (see Figure 5). , or a method in which a hole is made in the formed concrete floor plate (2) and a retaining bolt (1) is driven into the hole (in the hole) to fix it.Especially for the latter, It is most convenient for construction to widen the driving capital with a wedge and fix it by frictional force against the perforated wall σii Vc (see Fig. 6).0 Also, the spacer (41) can be used as the holding member (4). If the holding member (4) is welded and placed above the embedded material (3), the holding member 111S (4) can be used as a spacer as it is, and reinforcing reinforcement can be easily arranged (No. (See Figures 7 and 8).

Furthermore, as the concrete floor plate (2), it is also possible to use a PC board in addition to the Ld% on-site casting.

On the other hand, when stacking a plurality of embedding materials (3), each of them has 0υ unevenness that fits into each other when stacked. By forming a 2+-shaped fitting part, it is possible to prevent each part from shifting, making it easier to identify the embedded material, and to achieve stronger fixation (Figs. 9 to 4i1', (See Figure 12). 'Water-resistant cardboard can also be used as the embedding material (3).

According to the construction method according to the above-mentioned origin, an embedded material (3) made of lightweight solid material is placed on a concrete floor plate (2) on which a resting member (1) has been erected in advance, After arranging the holding member (4) on the embedded material (8) and connecting the holding member (4) to the locking member (1) to fix the embedded material (8), the concrete floor plate (2 Since this construction method involves pouring concrete (Q) for floor height adjustment on top of (2) K, the fixing work of the embedded material (8) to the concrete floor & (2) K can be done very easily and efficiently. Its fixation is also 1
It can be done firmly, and the embedding material (8) does not shift or float during concrete pouring, and it is possible to perform a (C) embedding work with a good setting.

1. If a V IC locking member (1) of divine length is used, it will be easy to fix according to the height of the embedded material (3), and it can be used for a wide variety of raising heights. ^J It will simply be possible to deal with it.

Therefore, it can greatly contribute to shortening the time required for raising construction and reducing costs, and is suitable for applications such as raising the floor of bridges as well as buildings such as apartment complexes, general buildings, and warehouses. This means that we can offer one construction method.
