Abstract

PURPOSE:To facilitate constructing side walls of height and width which meet design conditions by a method in which desired block boards having joint reinforcing bars exposed in given positions are beforehand produced as structures of various standards for a formwork having a concrete discharge port. CONSTITUTION:A main block board A is formed by placing concrete into the back side 1-a where joint reinforcing bars 1 are exposed in a formwork having a concrete discharge port 7 to form structures of various dimensional standards. The block board A is combined with a side wall B whose height and width are adjustable, which does not constitute floor or wall face. The concrete is degassed by application of a vibrator to remove excess air to closely joint them without aperture in the top face 6. Various kinds of products having side walls with variable height and widths which meet design requirements can thus be easily obtained by producing main block boards A in advance.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is applicable to poured concrete products for circular side gutters, underground common drains, and sewage manholes that require relatively large and multi-walled shapes or K-side decorative models. Adjustable side gutter with single clasp, bulkhead +. Since formwork depreciation is too expensive in the manufacture of products such as roads and environmental retaining walls, we have developed a manufacturing method that makes it possible to easily manufacture various products with a low ML of formwork depreciation costs, and these products. It is something that flashes in my mind. <V-bundle technology> Large-scale conventional concrete precast products or
The following are the manufacturing methods and products for environmental products.

1゛) If not shown in the diagram, use the frame to identify the jet, and pipe the concrete from the lower plate or back side. Pour the concrete for 3 hours, remove excess air from the concrete and place it on the second concrete casting surface, and perform initial curing (concrete ~
Because it requires moisture during hardening, it is cured in a 2-air oven or in an autoclave, and has an initial compressive strength of 811~lIl.

12) Method of manufacturing by demolding at step 12). ■For products such as circular side ditches, bulkhead waterways, underground communal waterways, and boxes, the width of the formwork is set to the maximum width of the product as the basic formwork, and the product is slid as needed.■Produced in the same manner using the H method.

■ Environmental earth retaining walls (L-shaped retaining walls, inverted T retaining walls, floor slab concrete extension retaining walls) are sheep-shaped frames with low-grade walls (low side) 3
Or back A. When it becomes super large, the wall side 5. ■There was a similar method of making money. However, these methods had the following drawbacks. (■ Conventional disadvantages and purpose of the invention) A single fixed formwork (a formwork that cannot be changed even if the height 211 changes) is used for low plate 3 or back plate 4 or wall surface 5. The formwork and manufacturing method in which concrete is poured from the side do not require replacement or installation of attachments, so there is no possibility of dimensional deviations in the finished product, and product construction is easy even when manufactured using multiple formworks, and there is no difference in construction Ig. Although it is small, the height of the product standard, rl+.
A mold of #1 is required, and for this reason, the depreciation cost of the mold occupies a large proportion of the product original product (e.g., No. 111: m.
IM height 3000 x floor slab width 210 (jy: length 2 (
111 (1 unit with L size: approx. 2.5 million yen, width of 12l2I + 01107 height 20110 In order to increase the cost (I1 [0-351) million yen at 4111111+++++), a considerable amount of site setup was required. If the molding process is not in place, precast products will be more expensive than on-site construction, making it impossible to use them. The method of manufacturing products by sliding them to the required width greatly reduces the formwork depreciation cost compared to the product cost, and the RL is also comparable to the replacement of attachments.
A baby product can be produced at fi≠, but since the basic formwork is made of large material, a large manufacturing space is required, and it is difficult to move concrete for concrete pouring and cattle removal, and it is difficult to install and replace attachments before product production. The larger the product in terms of bundle-E length,
There was a constant flow of complaints from the field as a result of errors occurring. The height of the wall between the top and the top is 1500 ~ 20110 ~
301,101, the larger the concrete pouring surface, the more difficult it is to assemble and remove the formwork, and the longer the molding time due to the shape of the product.
), addition of reinforcing bars, hanging hardware for demolding and reversing, issues with aesthetic air bubbles in concrete, ensuring a safe work area during concrete pouring, manufacturing time for products with beveled tops, sheep-shank products, etc. Problems with joint errors during construction required more effort than the cost of the formwork. (Three Problems to be Solved by the Invention) Therefore, the inventor of the 1A construction method and product of the present invention designed these sills, manufactured the products at the T shop, and carried out the top wood work on site. While listening to the following, t1 is the problem to be solved by the invention,●<T) IIf of the formwork

Insert the concrete and pour the concrete. At this time, the main block A. Concrete is poured using a vibrator with low vibration transmission (a rod-shaped vibrator is also good) that does not transmit much vibration, and the concrete is poured with a trowel on the pouring surface.
- For concrete precast products to be manufactured using WIA construction, use the methods described above to complete the entire product by removing the initial curing and erecting formwork by brushing and brushing. The following advantages and products can be produced.

《Operations and Effects of the Invention》 ■ During product manufacturing, k》 also applies bending stress to parts I1.
Since products manufactured by i+ are used as part of the formwork, the formwork for other parts is not only light in weight, but also the formwork cost is extremely low because the formwork itself is not messy. Not only that, but also the μ motion is IF 6P) (2) Design [], Q. Floor slab 11-r 7. A. Even if the concrete is poured in a formwork with a -F surface, and the attachment is replaced, the casting height (the height of the formwork, in the case of the product, the floor slab thickness or wall I section) is low. It is easy to replace, and the 2-side J-K is also simple.

It is easy to create a wide variety of products with sidewall heights that match the measurement conditions or variations within a single product. ■ Since the reinforcing bars are divided, processing and assembly is easy! Since IliL does not require any space even when folded, it is easy to manage the factory and insert into formwork.

■ Is the top of the product before curing the product after the curing material age has passed?9. IO ~ As shown in Figure 11, the lower surface after product construction or
Even if there are cooling holes for initial withering curing in the part l) that meets the back, there is no aesthetic problem.■ Main edition A. The connecting reinforcing bars are IFI! B. The concrete is inserted intersecting with the reinforcing bar 2, and the concrete on the concrete pouring surface is pushed out from the concrete discharge L], so the adhesion of the concrete is good, and the stress level of the integrally manufactured product is completely ensured. Not only that, but the main reinforcing bar (H.L.I shape steel may also be used) can be easily reinforced, and in addition, it can be reinforced by spraying cement or using adhesive on the pouring joint surface. Much stronger product power than existing products':1'. J: Ru.

■ Chapter 7.9. Is it important for products such as IO diagram products that require slippage on the flow wall surface or the inner surface of the cavern stem to be unable to remove air bubbles like conventional products? Not only does this eliminate the need for wheat repair (crater repair), but it also increases the m degree coefficient for product flow rate calculations. ■ By adopting the split manufacturing and joining method, 4.5.
