Description

[Detailed Description of the Invention] The present invention aims to provide a formwork device that is extremely useful when producing walls and floor slabs of various buildings using cast-in-place concrete.

In other words, the form work required to construct walls using cast-in-place concrete has a significant impact on the overall construction period and economy.

Conventionally, when performing formwork construction, a large amount of timber was used, which had to be assembled and removed. Since holes for separators had to be drilled in the formwork, the range of use of the formwork for other construction work was limited, and the economic effect of the formwork's versatility was low.

Furthermore, construction methods have already been developed that use aluminum formwork and the like to eliminate the use of end pieces or to significantly reduce the amount of end use. Since the formwork itself must bear the entire load during concrete pouring, considerable strength is required for the formwork, and sufficient consideration must be given to ensure that there is no risk of deformation at the joint. However, even though it does not use thick timber, it is rather expensive and impractical.

The present invention was developed in view of the above points, and
Without using large-scale mechanical equipment or cut materials,
Formwork construction can be carried out extremely labor-savingly and economically, and the formwork can be used for other purposes.In addition, it is easy to correct errors during construction, and wall construction can be carried out very efficiently. It is an object of the present invention to obtain a formwork device capable of creating a floor slab.

Embodiments of the present invention will be described in detail below based on the drawings.

FIG. 1 and FIG. 2 are an overall view and an enlarged view of the main parts of a wall frame 3 that has been prepared in advance in a factory, and this is a
It is constructed by welding lattice-shaped steel frames 1... fixedly connected in a rectangular shape, and welding reinforcing bars 2... to both sides at predetermined intervals in a vertical and horizontal lattice pattern. Channel steel materials 5, 5, etc. for attaching formwork for concrete pouring are connected and supported via separators 4, at multiple locations spaced apart vertically at appropriate intervals, with required cover gaps. , the concrete pouring form 11 is positioned within the vertical interval width of both channel steel materials 5, 5 arranged at a distance from each other, and the formwork 11 for concrete pouring is placed between the steel materials 5, 5 while sandwiching it from above and below. It is something that stays attached.

Among these channel steel materials 5, 5..., the steel materials 5a, 5a for the setting base at the lower end (or upper end, or both upper and lower ends) of the frame frame 3 are divided into two vertically, and the upper and lower ends thereof are cut into two. It is constructed so that the direction and center can be freely changed and adjusted.

Incidentally, 90-degree joint angles 6.6 are fixed to the steel frames 1 at both ends of the frame 3 in the direction of the ends so as to obtain the wall joints shown in FIG. 3.

Next, a procedure for producing a desired wall 3A on site using the frame 3 configured as described above will be explained step by step.

■ After the frame 3 is delivered to the site, it is attached to the above-mentioned joint on the foundation beam 10 which has a footing only in the end direction and has joining reinforcements 8... and anchor bolts 9 for formwork panel joints. It is assembled and installed at a predetermined location sequentially via the angle 6.6.

Errors in construction at this time, as well as errors in construction between the upper and lower frames 13, 3 in the frame frame 3 for walls on the second floor and above, are determined by the end steel members 5a, 5a, which are the setting bases.
Make appropriate adjustments by changing the top and bottom of the screen to ensure error-free installation.

(See Figures 4 and 5.) After that, the channel steel materials 5, 5° 5a, 5a and the separator described above are used.

Formworks 11 made of plastic or metal are removably installed in a laminated state via U-grips 13, and then a waterproofing agent is sprayed to eliminate water absorption. Aerated concrete 7 is poured.

(See Figures 6 to 8) ■ Then, when this aerated concrete 5 hardens and curing on an appropriate date is completed, the formwork 11... and the channel steel 5. 5. 5a,
By removing 5a..., a wall 3A as shown in FIG. 9 is constructed.

As is clear from the details described in the examples above, in short, the formwork device for manufacturing walls and floor slabs of buildings according to the present invention is suitable for forming walls of buildings manufactured by a combination of steel frames and reinforcing bars. At multiple locations above and below the left and right sides of the frame frame, install horizontally long steel materials for attaching the formwork for pouring concrete.
The steel materials are arranged at approximately the same distance in the vertical direction as the vertical width of the formwork for concrete pouring, and the steel members are connected and supported by the frame through separators attached to the frame; Between adjacent steel materials,
The formwork for concrete pouring is inserted and arranged in parallel along the longitudinal direction of the steel materials, and the formwork is fixed in a state where it is sandwiched from above and below by the steel materials above and below, and the frame frame of the steel materials is The steel material at the upper end, the lower end, or both upper and lower ends is divided vertically into two, and the width in the vertical direction can be freely changed and adjusted, so that the following effects are achieved.

A ■ Since the formwork device can be constructed by supporting a horizontally long steel material for attaching formwork for concrete pouring on a frame frame and sandwiching the formwork from above and below with this steel material, it is possible to construct a formwork device with a large number of ends. Formwork work can be carried out in a short time without requiring labor, without requiring the complicated work of assembling and removing thick timbers.

◎ When supporting the formwork on the frame, the formwork is not directly connected to the end of the separator fixed to the frame, but the steel material is integrated with the frame using the separator attached to the frame, and the steel material is utilized. Since the formwork is held in place by being clamped from above and below, there is no need to drill holes for inserting the separator in the part of the formwork facing the concrete pouring space. When disassembling and reusing for other construction work, there is no need for processing such as closing the holes or creating new holes, which significantly increases the reusability of formwork constituent materials and allows formwork work to be carried out economically. It has the advantage of

Using the frame frame with an O-rigid structure as a anchor, a long steel member is fixed in the horizontal direction, and the formwork is fixed to this steel member, so the position and posture of this steel member can be maintained stably and firmly, and the frame is The relative posture and position of the formwork relative to the frame can be easily determined.

■ Since the weight of the formwork is placed on the sturdy steel material whose proper mounting position has been determined, and the formwork is installed horizontally along the length of this steel material, a large number of sheets are used. It is easy to install formwork in almost a straight line with the vertical heights determined, and the work of assembling formwork can be done very quickly and easily, making it possible to carry out formwork work labor-savingly and accurately. can.

■ Also, since the formwork is attached to a long steel material in the horizontal direction, it is possible to use a sturdy steel material that has been fixed in the proper mounting position as described above, as if it were a type of concrete measuring device used to measure the thickness of poured concrete. It can be used as a ruler, and by attaching the formwork to such steel material, the surface of each formwork facing the concrete pouring space can be positioned almost horizontally in a straight line while the concrete pouring thickness is accurately set. Cheap.

Therefore, it is advantageous in that it is possible to accurately set the concrete pouring thickness and to obtain the advantage that there are few defects such as unevenness on the concrete surface after pouring.

B Although the present invention has the above-mentioned superior advantages, it particularly has the following points as its greatest feature.

That is, since the steel materials at the upper or lower end or both upper and lower ends of the frame frame are divided vertically into two, and the vertical width of the steel materials can be freely changed and adjusted, errors in construction can be easily corrected. In particular,
For example, even if the formwork device is placed facing a fixed part such as a foundation beam, since the steel members 5a, 5a are divided into two parts, only the steel member 5a on the side that contacts the formwork is subjected to the construction. The position can be changed in order to absorb the above error, etc., and compared to the case where the structure is not divided into two parts, the position can be changed between the fixed part and this steel material, or between the fixed part and the frame frame, or with the frame frame to absorb the error. This has made it possible to completely eliminate the need for complicated processes such as interposing seam material between parts, and to perform formwork work with high precision in an extremely efficient manner.
