Description

[Detailed description of the invention] This invention is a face plate (roof plate, etc.) that is laid on a concrete-concrete surface (for example, a roof) of a building or structure for the purpose of fire prevention, waterproofing, or decoration.
This invention relates to a face plate construction structure for a building or structure that is constructed horizontally or at a desired inclination.

For the roof or equivalent part of a building or structure where concrete is poured, the surface where the concrete is poured should be exposed as is in order to improve fire protection, prevent external influences such as erosion and seepage caused by rainwater, or for aesthetic reasons. Rather than keeping
A face plate is often installed.

However, when pouring concrete onto a roof, etc., the concrete itself does not have much fluidity, so it is difficult to make the pouring surface flat, and it is generally sloped in a certain direction, or
Alternatively, unevenness may occur partially.

Even if a roof plate is laid on this concrete pouring surface, a portion of the entire roof is sloped or has irregularities corresponding to the concrete pouring surface, making it extremely difficult to construct the roof evenly.

The present invention was developed in view of these circumstances, and its feature is that multiple anchors with female screw holes are buried in the concrete pouring surface such as the roof, and positioning fittings are attached to these anchors using bolts and nuts. By leveling and installing the metal fittings and using this metal fitting as a reference, it is possible to lay roof plates and other face plates horizontally without slope or unevenness, or at a desired slope, regardless of the surface condition of the concrete pouring surface. It has a face plate construction structure.

Also, when laying the face plate, rafters are installed and fixed between the positioning fittings, but during actual construction, the fixing positions of the fittings and the rafters may be slightly different (for example, concrete The anchor is designed to be fixed with some margin (due to errors in embedding, such as not being able to bury the anchor in the desired position due to reinforcing bars inside the construction surface being in the way, and errors in assembly during construction, etc.).

Hereinafter, an embodiment of a roof to which the present invention is applied will be explained with reference to the drawings. 1... is an anchor, and in the case of this embodiment, a female threaded hole 2 is provided in the axial direction at approximately the center of the anchor. .

When using it, when pouring concrete,
They are buried in the concrete placement surface 3 in rows aligned at desired positions (for example, positions for supporting rafters as described later).

In this case, there is no need to make the surface condition of the concrete pouring surface particularly accurate, and anchoring can be carried out easily and quickly even though the height position can be set approximately.

Next, wait for the concrete to harden, and then...
・Insert the bolt 4 into the female screw hole 2 and screw it in.

However, a mounting hole 6 is formed in a concave portion 5a in which a groove-shaped downward positioning fitting 5 is formed approximately in the center of the lower surface of the bolt head 4a.
, and screw the nut 7 from below to fix it.

The bolt 4 with the positioning metal fitting 5 fixed in this way is placed in the position where the metal fitting 5 is leveled.For example, place a thread or plate on the row of anchors and level it using a spirit level or the like. Anchor to the position where you put out...
After screwing into the female screw hole 2 of..., the nut 8, which has been screwed onto the bolt 4 in advance, is lowered into the end 1a of the anchor screw hole and screwed into engagement to fix it.

As a result, the line connecting the upper surfaces of each positioning fitting 5 becomes horizontal or in a desired inclined state, regardless of the unevenness or inclined state of the concrete placement surface 3.

In the case of this embodiment, the positioning fitting 5 is as shown in FIG.
The groove shape is formed by pressing or the like and reinforced with downwardly extending portions on both side edges, but is not particularly limited, and may be a simple flat plate depending on the case.

Further, although a recess 5a is provided approximately in the center to accommodate the head 4a of the bolt 4, the present invention is not limited to this, and the head 4a may protrude (however, as described later, this If the rafter member installed on the upper surface is in the shape of a flat plate, it is preferable that there be a recess 5a).

A groove-shaped rafter member 9 is placed facing downward between at least two or more metal fittings of each positioning tool 5 fixed in this way, for example, metal fittings aligned in a row in either direction of the roof. erect.

In this case, the rafter member 9 is not particularly limited and may be made of wood or the like, but in this embodiment, it is made of a metal material, and the lower ends of the left and right side surfaces extend outward to form the edges 10, 10. ,
This edge 10 is placed on the upper surface of the metal fitting 5.

The reason why this rafter member is made into a groove type is to improve the strength and at the same time to use the step space defined by the top surface and edge of the groove as a heat insulating space as described later. It may also be a rafter member in the form of a flat plate.

In the case of a flat plate, it is preferable to have a structure in which the bolt head 4a is accommodated in the recess 5a of the metal fitting 5 as described above.

Although the concrete fixing of the rafter member 9 and the positioning fitting 5 is not particularly limited, the overlapped edge 10 and the fitting 5 are
This may be done by providing through holes 10a and 5b in the upper surface of the case, respectively, and attaching fixing means 15 made of bolts, nuts, bands, etc. to these through holes 10a and 5b, or by welding these parts. It's okay.

When using the bolt and nut fixing means described above, the through holes 10a and 5b may be slightly misaligned during actual construction.

For example, if the anchor cannot be buried in the desired position because the reinforcing bars on the concrete pouring surface get in the way, or if there is an error in the buried position due to the anchor moving during concrete pouring, the assembly may have errors due to the construction at the time. It is preferable to make each through hole 10a, 5b a long hole in the direction to absorb the error so that there is some margin.

In the case of this embodiment, the through hole 5b is lengthened in the direction perpendicular to the rafter member 9 to absorb the error in the width direction of the rafter member 9, and the through hole 10a is lengthened in the axial direction of the rafter member 9 to absorb the error in the width direction of the rafter member 9. This is to absorb the error.

Furthermore, instead of long holes, a plurality of rows of small holes may be formed.

Therefore, the anchor can be buried and each part can be constructed quickly without much care.

In this way, a plurality of raft members 9 are arranged in parallel at desired intervals on the concrete pouring surface 3 of the roof.

On the top surface of this raft member is a face plate 11 as a roof plate...
Lay them out side by side.

Various known roof plates can be used, but for example, a retaining part 12 shaped like an upward U-shape is provided on the upper edge, and a locking part 13 formed in a downward U-shape is formed on the lower edge. In the case of using the rafter member 9, cut and raised claws 14 are formed in the length direction on the upper surface of the rafter member 9, and the downward hook-shaped fastening portion 14' at the tip of the claw is attached to the engaging portion 12. Fit it in and hit it with a hammer to secure it.

Next, the locking portion 13 of another roof board adjacent to this part is placed over and locked, and the roof boards are laid one after another.

Since the positioning metal fittings 5 fixed to the anchors 1 are leveled, the roof sheets laid in this way are placed horizontally or as desired with high accuracy as a whole, without being slanted or uneven in some parts. It will be constructed on a slope.

If further necessary, the adjacent rafter members 9
, 9, pass the roofing board 16 between the edges 10, 10 of the roof board 1
1, and fill this space with a heat insulating material 17 as in the case of this embodiment to improve the heat insulation effect, or leave it as a space and let air in from the eaves. It is designed to exhaust air from the ridge, but it may also be used as a dew condensation space.

As is clear from the above, according to the present invention, it is possible to easily and quickly level the face plate or construct the desired slope on the concrete pouring surface of a building or structure, regardless of the flatness of the concrete pouring. I can do it.

In addition, since the positioning bracket and the rafter members can be fixed with some margin, even if there are errors in embedding the anchors or installation errors during construction, there will be no problems and the leveling can be achieved quickly. can be done.

In the above embodiments, the case of a concrete roof has been explained, but the present invention is applicable not only to the case of a roof but also to the case of constructing a face plate on other conch notebook surfaces that have similar problems. , it can be applied without changing its gist.
