Description

Technical Field

[0001] This utility model relates to the field of housing construction, specifically to an insulation board for building exterior walls. Background Technology

[0002] With global economic development and a severe energy situation, building energy conservation has become a global trend and a necessity. Currently, both domestically and internationally, the most widely used energy-saving measure for building envelopes is the external wall insulation system.

[0003] In related technologies, the external wall insulation system of a building usually involves pasting insulation boards onto the exterior wall. After applying adhesive mortar to the insulation boards, they are bonded to the wall. The center and sides of the insulation boards are tapped to make them adhere firmly. However, under long-term exposure to wind, sun and rain, the insulation boards are prone to falling off. Utility Model Content

[0004] The purpose of this utility model is to provide an insulation board for building exterior walls to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a thermal insulation board for building exterior walls, comprising at least two boards and a connecting plate. Two connecting grooves are symmetrically arranged on the front part of the outer walls on both sides of the boards. Multiple first mounting holes are provided at equal intervals along the top of the inner wall of the connecting groove. The connecting plate is embedded into the connecting groove between two adjacent boards. Two sets of multiple second mounting holes are symmetrically arranged on the outer wall of the connecting plate at equal intervals along the side wall of the connecting plate. The number and position of each set of second mounting holes correspond to the first mounting holes.

[0006] Furthermore, a first connecting strip extends from the rear of the top of the plate, a first limiting strip extends from the upper part of the front sidewall of the first connecting strip, a first connecting groove for the first connecting strip to be inserted is provided at the rear of the bottom of the plate, and a first limiting groove for the first limiting strip to be inserted is provided on the inner front wall of the first connecting groove.

[0007] Furthermore, a second connecting strip extends from the rear of the top of the connecting plate, a second limiting block extends from the upper part of the front sidewall of the second connecting strip, a second connecting groove for the second connecting strip to be inserted is provided at the rear of the bottom of the plate, and a second limiting groove for the second limiting block to be inserted is provided on the inner front wall of the second connecting groove.

[0008] Furthermore, two sets of locking blocks are symmetrically arranged on the outer walls of both sides of the connecting plate at equal intervals along the side walls of the connecting plate, and the inner wall of the connecting groove is provided with slots at equal intervals, the number and position of which correspond to each set of locking blocks, and the locking blocks are engaged into the slots at the corresponding positions.

[0009] Furthermore, the distance between the two outer walls of the card block is set to gradually decrease from the outside to the inside.

[0010] The beneficial effects achieved by this utility model are as follows: By adopting a dual fixing method of bonding with adhesive mortar and mechanical fastening with expansion screws, the expansion screws pass through the first mounting hole of the board and the second mounting hole of the connecting plate (the positions and numbers correspond precisely) to the wall. At the same time, the connecting plate is embedded in the connecting groove of the adjacent board, which greatly improves the connection strength between the insulation board and the wall and between adjacent boards, effectively resists wind and rain erosion, and avoids the risk of falling off.

[0011] Vertically adjacent panels are positioned by fitting and limiting each other with the first connecting strip and the first connecting groove, and the first limiting strip and the first limiting groove. Vertically adjacent connecting panels are fitted and limited by fitting and limiting each other with the second connecting strip and the second connecting groove, and the second limiting block and the second limiting groove, which effectively improves the overall vertical connectivity of the insulation board.

[0012] The connecting plate engages with the connecting groove of the plate body via a locking block. The design of the locking block, which is wider on the outside and narrower on the inside, makes the engagement tighter and less prone to loosening. In addition, expansion screws are used to fasten the plate through the mounting holes. This double fixation enhances the connection stability of horizontally adjacent plates and prevents them from falling off. Attached Figure Description
