Description

[Detailed Description of the Invention] The present invention relates to a dew condensation prevention connector for a building insert for preventing dew condensation from rooftop slabs and exterior walls in concrete structures in cold regions.

Conventionally, localized condensation is noticeable on inserts buried in concrete, and condensation is often seen on ceiling panels.

As shown in Figure 9, metal inserts A are installed on formwork P and heat insulating material and buried in concrete C, and then a metal anchor body a with high thermal conductivity and its threaded part are installed. The suspension pole (which is screwed directly into the female thread) penetrates the insulation material and is further connected to the lightweight section steel that is popularly used these days, so the heat flow is shortened and the heat on the high temperature side is When replenishment is low and heat absorption or radiation on the low temperature side is intense, a cold-thermal bridge occurs and local condensation occurs.

The connector of the present invention is provided to solve the above problems.

Next, the connector according to the present invention will be explained with reference to drawings of embodiments.

1 and 2 show a perspective view and a central vertical sectional view of the first embodiment.

Reference numeral 1 denotes a reinforced plastic connector, with a male threaded part 2 screwed into the anchor body of the insert at the top, and a female threaded part 3 screwed into the hanging bolt at the bottom, both on the same axis. It is made by cutting the edge 1a with a certain thickness at the part.

Furthermore, 4 is a flange provided integrally on the outer periphery of the central portion of this connector 1, and has an edge 4a formed on the outer periphery.

The connector 1 having the above structure is an inserter as shown in FIG.
A is attached to the insulation material in advance and concrete is poured, and after curing, the formwork (not shown) is removed from the mold, and the upper male threaded part 2 is inserted into the anchor body A of the insert A.
1, and press the edge 4a of the flange 4 against the heat insulating material to attach it, and then screw the hanging pole (B) into the female threaded part 3 of the flange 4 to support a lightweight ceiling base material, etc. can.

For this reason, the anchor body of the insert A buried in the concrete and the hanging pole) B are connected using a connecting tool 1 with low thermal conductivity.
This prevents local condensation from occurring without short-circuiting the heat flow.

Furthermore, by pressing the flange against the surface of the heat insulating material, condensation on the lower end of the anchor body becomes invisible.

In addition, by making it made of reinforced plastic, the strength against hanging loads can be improved compared to that of ordinary plastic.

FIG. 4 shows a vertical cross-sectional view of a main part of a second embodiment of the coupling device of the present invention, in which a metal male threaded portion (screw shaft) 22 is embedded or screwed into the upper part of a reinforced plastic coupling device 21. This makes it possible to improve bending strength.

FIG. 5 shows a usage diagram of the third embodiment of the coupling device of the present invention, in which the anchor body A1 is short and made of reinforced plastic in order to fit the inserter (A) that comes into contact with the upper surface of the insulation material. Connect the male threaded portion 32 of the connector 31 to the anchor body A1.
This connector 31 is screwed into the female thread A2 of the insert, and is installed by pushing it into the heat insulating material.This allows the anchor body of the insert to be installed without penetrating the heat insulating material. Construction after dismantling the formwork is also easy.

FIG. 6 shows a usage state diagram according to a fourth embodiment of the coupling device of the present invention, in which the upper part of the reinforced plastic coupling device 41 and Female threaded parts 43 and 43 are provided at the lower part, the upper part is screwed into the male threaded part A2 of the anchor body A1 after dismantling the formwork, and the hanging bolt B is screwed into the lower part. Bending strength is improved.

FIG. 7 shows another usage state diagram according to the fourth embodiment of the coupling device of the present invention, in which the anchor part A1 is shortened and the anchor part A1 is made of reinforced plastic in order to be compatible with the insert A having a male threaded part A2 at the bottom. The female threaded part 43 at the top of the connector 41 is screwed into the male threaded part of the anchor body A4, and the connector 41 is pushed into the heat insulating material. It can be installed without penetrating the insulation material, and it is also easy to install after dismantling the formwork.

FIG. 8 shows a central longitudinal cross-sectional view of a fifth embodiment of the coupling device of the present invention, in which the center portion of the reinforced plastic coupling device 51 provided with female threaded portions 53 and 53 on the upper and lower sides is connected to the hollow portion 51 b. As a result, the volume of the connector 51 can be reduced to reduce costs, and heat conduction can be reduced.

In addition, the connector of the present invention has the support E of the insert removed and the anchor body of the insert connected to the main body.
It can also be installed by bolting directly to the formwork.

Furthermore, it is easy to imagine that dew condensation prevention can be made more effective by making the anchor body of the insert also made of reinforced plastic.

According to the dew prevention connector of the present invention as described above, the metal insert buried in the concrete and the hanging bolt for suspending the lightweight ceiling base material, etc. are connected to a reinforced plastic material with low thermal conductivity. Since the two parts are completely separated at the same time as they are connected by the connector, there is no possibility of short-circuiting the heat flow, and there is an effect of eliminating the cold-heat bridge and prematurely preventing local dew condensation.

Further, the connector of the present invention has a simple structure and is easy to construct, which is useful in practical terms.
