Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a thermal insulation board technical field, specifically to a kind of thermal insulation board for building outer wall with rainwater penetration reduction. BACKGROUND
[0002] With the improvement of living standards, people more and more hope that the wall of house is more warm, and the outer wall insulation board successfully solves this problem, and the outer wall insulation board can not only ensure the comfortable living environment of indoor through the heat insulation effect, but also can prevent the waste of energy.
[0003] The outer wall insulation board is generally fixed with the wall surface by adhesive method at present, and when it rains, rainwater flows downward or obliquely downward along the thermal insulation board, which is easy to penetrate into the joint gap between two thermal insulation boards, causing the thermal insulation board and the wall surface to be in a damp state for a long time, affecting the service life. UTILITY MODEL CONTENTS
[0004] The utility model discloses a kind of thermal insulation board for building outer wall with rainwater penetration reduction, can effectively guide rainwater, reduce the penetration of rainwater.
[0005] The utility model discloses a kind of thermal insulation board for building outer wall with rainwater penetration reduction, including vertical rectangular thermal insulation board, the left and right sides of vertical rectangular thermal insulation board outer side are vertically provided with drainage structure, the lower end of drainage structure is provided with connecting pipe, connecting pipe is partially inserted in the inside of the lower end of drainage structure and connecting pipe is bonded and sealed with the contact position of drainage structure, the side opposite to the lower end of drainage structure is provided with drainage port, the lower side of rectangular thermal insulation board outer side is provided with the flow guide groove that opens upwards, the middle of flow guide groove is high and both ends are low, and the both ends of flow guide groove are connected with the drainage port on drainage structure respectively.
[0006] The above technical solution is used, and the thermal insulation board of the above structure is adhered to each other on the building outer wall, and when adhering, the connecting pipe on the upper thermal insulation board is inserted into the drainage structure of the lower thermal insulation pipe, when it rains, rainwater hits on the thermal insulation board, and rainwater flows downward or obliquely downward along the thermal insulation board, when obliquely downward, drainage structure can play the role of interception, to prevent rainwater from entering the connecting portion of left and right thermal insulation boards, when rainwater contacts flow guide groove, rainwater is guided into drainage structure by flow guide groove, and then rainwater flows downward along drainage structure, so rainwater also cannot flow to the joint of upper and lower thermal insulation boards, to reduce the penetration of rainwater.
[0007] Further, the upper side of flow guide groove is provided with filter screen, and the filter screen can isolate larger impurities, to prevent larger impurities from entering drainage structure and causing the blockage of drainage structure.
[0008] Further, the side of the filter screen close to the rectangular heat preservation plate is higher than the side of the filter screen away from the rectangular heat preservation plate, so that the inside is higher and the outside is lower, which is beneficial to the larger impurities falling from the filter screen.
[0009] The building outer wall heat preservation plate disclosed by the utility model has the advantages that the drainage structure can play a blocking role, prevents rainwater from entering the connection part of the left and right heat preservation plates, and can guide the rainwater on the heat preservation plate into the drainage structure in time through the drainage groove, thereby preventing the rainwater from flowing through the joint part of the upper and lower heat preservation plates, and reducing the rainwater penetration. BRIEF DESCRIPTION OF DRAWINGS
[0010] Figure 1 It is a structural schematic view of the utility model embodiment 1.
[0011] Figure 2 It is a structural schematic view of the utility model embodiment 1 without the filter screen. DETAILED DESCRIPTION
[0012] In order to further explain the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes, the specific embodiments, structures, features and effects according to the utility model are described in detail as follows in combination with the drawings and the preferred embodiments.
[0013] Embodiment 1:
[0014] As shown in Figure 1 , 2 The utility model discloses a building outer wall heat preservation plate of reducing rainwater penetration, including vertical rectangular heat preservation plate 1, the left and right sides vertical setting of rectangular heat preservation plate 1 outer side face are provided with drainage structure 2, and the lower end of drainage structure 2 is provided with connecting pipe 3, and connecting pipe 3 is partially inserted in the inside of the lower end of drainage structure 2 and is bonded and sealed with the contact position of connecting pipe 3 and drainage structure 2, and the opposite side of the lower end of drainage structure 2 is provided with drainage port 6, and the lower side of the outer side face of rectangular heat preservation plate 1 is provided with the drainage groove 4 of opening upward, and the middle of drainage groove 4 is high and both ends are low, and the both ends of drainage groove 4 are connected with the drainage port 6 on drainage structure 2 respectively, and the upper side of drainage groove 4 is provided with filter screen 5, and the side of filter screen 5 close to rectangular heat preservation plate 1 is higher than the side of filter screen 5 away from rectangular heat preservation plate 1, so that the inside is higher and the outside is lower.
[0015] The technical scheme has the advantages that when the heat preservation plates are adhered to each other on the building outer wall, the connecting pipe 3 on the upper heat preservation plate is inserted into the drainage structure 2 of the lower heat preservation pipe, when it rains, the rainwater flows downward or obliquely downward along the heat preservation plate, the drainage structure 2 can intercept the rainwater to prevent the rainwater from entering the joint between the left and right heat preservation plates, when the rainwater flows through the filter screen 5, the larger impurities are intercepted, the rainwater is guided into the drainage structure 2 by the guide groove 4, and then the rainwater flows downward along the drainage structure 2, so the rainwater cannot flow to the joint between the upper and lower heat preservation plates, thereby reducing the penetration of the rainwater.
