Description

Reinforced rectangular cushion

The reinforced rectangular cushion of the present invention is a new fixture in the patent of "Improved Concrete Wall Structure with Thermal Insulation and Thermal Insulation". There are several clamp posts on both sides of the rectangular frame. After inserting the heat insulation board, it can prevent the board from being damaged. The impact of grouting sinks, and the grouting is full and sometimes floats.

The concrete wall structure is composed of steel and concrete. In order to solve the problem of sultry heat, traditional methods will add heat insulation material or paint reflective paint on the outer side of the concrete wall to reduce the heat absorption of the external wall and achieve the cooling effect. However, due to the appearance and building materials Occupies space and causes repeated consumption, waste of resources and increased costs due to the useful life. In order to improve the above-mentioned sultry problem, the inventor specially developed patent No. M508569. The patent in this case is an improvement in the structure of a concrete wall with thermal insulation and thermal insulation. The insulation board is embedded in the wall to form a temperature isolation layer. Keep the house warm in winter and cool in summer at a constant temperature.

However, the thermal insulation board in the concrete wall is embedded in a large area and flat. When the concrete is poured, the impact force is quite large, which easily causes the board to move and deviate from the center, resulting in uneven internal structure of the concrete wall. In order to solve this problem, the inventors used the previous patent to hang several ring cushions on the double-layer steel bars to maintain the distance between the steel bars and the heat insulation board and the template. The ring cushions are hung on the double-layer transverse bars. Only fix the insulation board in the middle of the wall. The impact of the concrete during grouting will cause the insulation board to sink, and when the concrete is filled, it will also cause the insulation board to float, so it must be blocked by sharp irons. fixed.

The construction of the sharp iron block passes through the heat insulation board, sticks to the cross bars (crossing above and below the cross bars), and then inserts to the formwork. As it withstands the ring cushion, the insulation board can be fixed in the middle of the concrete wall. When the formwork is removed, the tip of the tip iron block inserted into the formwork will be exposed outside the wall, and the tip body must be covered with cement again , But this can't show the effect that the professional clear water model construction method can't be constructed or modified.

It is obvious from this that the inventor’s previous patent for steel ring gaskets can only effectively fix the insulation board in the middle of the wall, and still needs the assistance of a sharp iron block to avoid the sinking or floating of the board, which causes slow construction and increased costs. , And can not be applied to the wall of the standard clear water mold construction method.

The purpose of the present invention is to provide a reinforced rectangular cushion for the construction of a concrete wall with built-in insulation panels. The center of the cushion is provided with a hole for the cross bars to hang through, which is used to hang the reinforced cushion on the cross bars. There are several clamping posts on both sides of the rectangular cushion. One clamping post is used to support the template, and the other clamping post is used for the heat insulation board to directly press, so that the clamping posts are inserted into the board to join each other. The insulation board is positioned in the middle of the concrete wall to maintain the distance between the steel bar and the insulation board and the formwork. The fixing of the card column replaces the sharp iron block in the previous patent, avoiding the sinking and floating of the insulation board, and saving a lot of construction Complicated process and time.

In order to achieve the above objective, the reinforced rectangular cushion disclosed in the present invention mainly includes a rectangular frame with a plane on three sides and two elastic holding arms on the other side. The center of the frame has a sleeve hole for the horizontal ribs to hang through. The sleeve hole and the frame are connected by a number of connecting ribs, and the two sides of the rectangular frame are provided with a number of card posts, borrowed from the top of the card post Outside the formwork, the other side of the card post is for the heat insulation board to be directly pressed, so that the card post is inserted into the board, through the barb structure of the card post, the heat insulation board and the card post are firmly joined without sinking or floating due to grouting. And by the contact surface between the frame plane and the heat insulation board The increase of the product reduces the subsidence of the steel bar cushion, so the insulation board can be more maintained in the middle of the wall without shifting back and forth.

Please refer to Figures 1 and 2, the reinforced rectangular cushion of the present invention includes a rectangular frame 1 and two elastic holding arms. The frame is made of plastic material and is composed of three-sided flat surfaces and one-sided slot 16 , The side planes 10, 11 of the rectangular frame 1 are provided with a number of clamping posts 12, 120, the front end of each clamping post forms a wider cone and barbs 121, 122 are generated, and the frame extends from the inner surface to connect The rib 13 is connected to the sleeve hole 14, and a reinforcing structure 15 is provided on the periphery of the sleeve hole 14 to strengthen the structure of the rectangular frame 1.

The elastic holding arm is integrally formed on the rectangular frame 1 and includes an elastic arm portion 20 and a holding portion 21. The elastic arm portion 20 extends from the frame to the sleeve hole 14. The front end has a holding portion 21 positioned on the sleeve hole 14 side The flange and the sleeve hole 14 can jointly frame the transverse rib 3 to resist the steel bar and be positioned in the sleeve hole 14. The elastic arm portion 20 is additionally provided with a connecting rib 24 and a reinforcing rib 23, thereby effectively increasing elasticity The overall structural strength of the holding arm. A slot 16 communicating with the sleeve hole 14 is formed between the two elastic holding arms. The width of the slot 16 is a horizontal V-shaped structure that tapers from right to left, and the transverse rib 3 can be inserted into the sleeve hole 14 through the slot 16.

Refer to Figure 3, when you want to assemble the reinforced rectangular cushion to the cross bar 3, you should place the slot 16 of the cushion to the right, and then press the cushion directly on the steel bar. The cross bar 3 will follow the elastic arm. 20 slides in the direction of the sleeve hole 14. When the horizontal rib 3 touches the elastic arm portion 20, it will simultaneously push the two elastic arm portions 20 outward and slide into the sleeve hole 14, and the elastic arm portion 20 will return to the elastic force and drive the two elastic arms. The holding part 21 is positioned so that the two holding parts 21 can bear against the transverse rib 3, and the holding part 21 and the sleeve hole 14 jointly frame the transverse rib 3, so that the cushion can be stably hung on the steel bar (see section 4, 5). Figure).

Referring to Figures 6 and 7, the reinforced rectangular cushion of the present invention is applied to a concrete wall with built-in insulation panels. The shape of the concrete wall is defined by two templates 4 respectively to define the predetermined thickness space of the wall. In this thickness, a heat insulation board 5 and two layers of steel bars are installed. The rectangular cushion of the steel bars is hung on the cross bars 3, passing through one side The clamping column 12 bears against the template 4 and separates the distance between the steel bar and the template 4. The installation of the heat insulation board 5 directly presses the clamping column 12 protruding from the plate toward the other side of the cushion, so that the clamping column on the side of the cushion 12 is inserted into the heat insulation board 5, through the barbs 121 of the clamping column 12, the board and the cushion are joined without loosening, and at the same time, the flat surfaces 10 or 11 on both sides of the rectangular frame 1 are against the heat insulation board 5, and the board It is positioned in the middle of the concrete wall, and separates the distance between the steel bar and the heat insulation board 5. It does not need to be fixed by a sharp iron block to prevent the plate from sinking or floating, simplifying the construction steps. When the double-layer mold is assembled, directly Pour concrete to complete the construction of thermal insulation and thermal insulation concrete wall. Since the front end of the card column of the cushion is a cone structure, the contact area is very small when it is placed on the formwork. After the concrete wall is demolished, the traces on the wall surface are quite subtle, and there is no iron stop point tail, which is enough to show a clear water mold. The leveling effect of the construction method increases the beauty.

Furthermore, because the material of the heat insulation board 5 is relatively soft, when the concrete is poured, the two sides of the reinforced rectangular cushion frame of the present invention are flat, and the contact area with the board is enlarged, which can reduce the rectangular shape. The subsidence of the frame body 1 prevents the heat insulation board 5 from deviating during grouting, and maintains a fixed distance between the steel bar and the heat insulation board, and the steel bar and the template 4.
