Abstract

An expansion joint strip is suitable for filling between a plurality of insulating bricks and forming a flat surface together with the insulating bricks. The expansion joint strip includes a base wall extending along a first direction, a surrounding wall surrounding the base wall, at least one partition wall, and a plurality of exhaust holes. The surrounding wall has two end wall portions respectively arranged at both ends of the base wall along the first direction, and two side wall portions connected between the end wall portions. The at least one partition wall, the base wall and the surrounding wall jointly define a plurality of chambers. The exhaust holes are arranged on the base wall, so that the chambers communicate with the outside. When it rains, the air in the cavity can be discharged through the vent holes, so that the present invention will not be driven by the air to float, and thus can maintain a flat surface together with the matched insulating bricks.

Description

Expansion joint strip

The invention relates to a roof covering layer, in particular to an expansion joint strip.

In the hot summer, the room temperature inside the house rises because of the direct sunlight on the roof of the building. In order to improve living comfort, air-conditioning is usually used to lower the room temperature. However, air-conditioning consumes a huge amount of electricity, which is not good for the environment and requires a considerable amount of electricity bills. If good construction methods are used to prevent heat energy from entering the room, the aforementioned problems can be solved from the source and the required costs can be reduced. Common construction methods include covering the roof with thermal insulation bricks, so that the roof has an insulation effect, effectively preventing the heat energy brought by sunlight from entering the house, making the house cooler and reducing the electrical energy consumed by the air-conditioning Air-conditioning is required.

In order to prevent the aforementioned thermal insulation bricks from being damaged due to thermal expansion and contraction, expansion joints will be reserved between the thermal insulation bricks during laying, so that the aforementioned thermal insulation bricks can expand or contract without causing cracks. These expansion joints will be filled with expansion joint strips to keep the laid surface smooth. An expansion joint strip as disclosed in the Republic of China Patent No. M331015 is an elastic body and defines a plurality of elastic spaces. Embedded between the aforementioned insulation tiles In the case of expansion joints, the aforementioned existing expansion joint strips can form a flat surface with the insulation bricks, and produce a buffer effect to prevent the insulation bricks from being damaged.

But when it rains, if rainwater penetrates into these elastic spaces, the air originally in the elastic spaces will be squeezed and discharged from the place where the fitting is less tight (usually two existing expansion joints are adjacent to each other) The joints), resulting in the existing expansion joint strips being driven by air and floating, and thus unable to maintain a flat surface.

Therefore, the purpose of the present invention is to provide an expansion joint strip with a venting effect.

Therefore, the expansion joint strip of the present invention is suitable for filling between a plurality of insulating bricks and forming a flat surface together with the insulating bricks. The expansion joint strip includes a base wall, a surrounding wall, at least one partition wall, and a plurality of exhaust holes.

The base wall is made of soft material and extends along a first direction to be a long strip. The surrounding wall is made of a soft material and surrounds the base wall and extends from the base wall in a second direction perpendicular to the first direction. The surrounding wall has two ends respectively disposed at both ends of the base wall along the first direction The wall portion and two side wall portions connected between the end wall portions and spaced apart from each other. The at least one partition wall is made of soft material and connected between the side wall parts and connected to the base wall. The at least one partition wall, the base wall and the surrounding wall jointly define a plurality of chambers. The exhaust holes are arranged on the base wall so that the chambers communicate with the outside. Each chamber corresponds to one or two vent holes.

The effect of the present invention is: when it rains, the air in the cavity can be discharged through the vent holes, so that the present invention will not be driven by the air to float, and then can maintain the flatness together with the matched heat insulation bricks s surface.

Other features and effects of the present invention will be clearly presented in the embodiments with reference to the drawings, in which: Figure 1 is an assembly diagram of multiple embodiments of the expansion joint strip of the present invention and multiple thermal insulation bricks; 2 is a perspective view of the embodiment; FIG. 3 is a perspective view of the embodiment in another direction; and FIG. 4 is a cross-sectional view along the line IV-IV in FIG. 3.

Referring to FIG. 1, an embodiment of the expansion joint strip of the present invention is suitable for filling between a plurality of insulating bricks 9 and forming a flat surface together with the insulating bricks 9. Referring to FIGS. 2, 3 and 4, this embodiment includes a base wall 1, a surrounding wall 2, three partition walls 3, and a plurality of exhaust holes 4.

The base wall 1 extends along a first direction D1 and is elongated.

The surrounding wall 2 surrounds the base wall 1 and extends from the base wall 1 in a second direction D2 perpendicular to the first direction D1. The surrounding wall 2 has two sections along the first direction. D1 is provided at the end wall portions 21 at both ends of the base wall 1, and two side wall portions 22 connected between the end wall portions 21 and spaced apart from each other.

The partition walls 3 are connected between the side wall portions 22 and connected to the base wall 1, and the partition walls 3, the base wall 1 and the surrounding wall 2 jointly define four chambers 5.

The exhaust holes 4 are arranged on the base wall 1 so that each cavity 5 is directly connected to the outside. In this embodiment, each chamber 5 corresponds to two exhaust holes, but in other examples, each chamber 5 may also correspond to one exhaust hole, and it is not limited thereto.

The base wall 1, the surrounding wall 2 and the partition walls 3 are all made of soft materials. In this embodiment, the base wall 1, the surrounding wall 2 and the partition walls 3 are made of rubber and are made by integral molding. However, this is just an example, and the materials and manufacturing methods used are not limited to this.

When it rains, rainwater will infiltrate the chambers 5, but because the chambers 5 are connected to the outside, when the air is discharged from the exhaust holes 4, it will not drive the present embodiment to float, so that it can cooperate with the The insulating bricks 9 together maintain a flat surface.

In summary, the expansion joint of the present invention can exhaust the air in the chamber 5 through the vents 4 when it rains, so that the present invention will not be driven by the air to float, and thus can be matched with The heat-insulating bricks 9 jointly maintain a flat surface, so it can indeed achieve the purpose of the invention.

However, the above are only examples of the present invention, and should not be used to limit the scope of implementation of the present invention. Any application for patent scope and patent specification according to the present invention Simple equivalent changes and modifications made to the content are still within the scope of the patent for the present invention.
