Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an external wall thermal insulation advanced water stopping construction device. Background Art

[0002] In the process of construction, in order to enhance the insulation of the building's exterior walls, rock wool exterior wall insulation boards are usually installed on the outside of the main wall. During construction, rock wool exterior wall insulation construction needs to be carried out after the main construction is completed. This is because, during the rock wool exterior wall insulation construction, the rock wool exterior wall insulation board is pasted on the outside of the wall. Because the exterior wall insulation rock wool has high water absorption, if the exterior wall insulation rock wool is inserted in advance, it is necessary to prevent the water used in the upper main exterior wall construction and the water from the exterior wall in the rainy season from flowing into the exterior wall insulation. Otherwise, the weight of the rock wool exterior wall insulation will increase sharply after absorbing water, resulting in large-scale shedding of insulation, causing safety hazards and requiring rework.

[0003] In current construction projects, there are clear requirements for the construction period. In order to shorten the construction period, two adjacent processes are usually cross-constructed on the construction site to save time.

[0004] In the two adjacent processes of floor main construction and rock wool exterior wall insulation construction, a cross-construction method will be used, that is, when the building construction is halfway through, the rock wool exterior wall insulation will be installed on the completed building at the same time. This requires waterproofing of the exterior wall of the building, and the water sources for exterior wall waterproofing include rainwater and construction water. The waterproofing points are mainly the rock wool board facade and the upper eaves. The exterior wall facade can be waterproofed with waterproof mortar, but there is a waterproof blind spot at the top of the eaves. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an external wall insulation advance water-stopping construction device in view of the deficiencies in the above-mentioned prior art, which uses an external wall intercepting ditch to be installed at the top of the eaves of a completed building to prevent construction water and rainwater from flowing from the top of the eaves to the wall, so that rock wool-type external wall insulation construction can be interspersed during the building construction to save construction time.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: an external wall insulation advance water-stopping construction device, including a plurality of intercepting grooves, each of which is fixed to the eaves of the external wall by a hinge, one side of each of the intercepting grooves is fitted with the external wall, each of the intercepting grooves is detachably connected in sequence along its length direction, and a rubber sealing layer is provided at the connection between two adjacent intercepting grooves.

[0007] Furthermore, the intercepting ditch comprises a ditch body, and a first bending plate bent downward in a horizontal direction is provided at one end of the ditch body close to the wall;

[0008] The hinge includes a Z-shaped plate in the longitudinal direction and a second bent plate fixed at the bottom of the Z-shaped plate, the second bent plate is bent upward in the horizontal direction, the longitudinal cross-section of the second bent plate is the same in shape and size as the longitudinal cross-section of the first bent plate and is centrally symmetrical, and the upper end of the Z-shaped plate is fixed to the eaves of the exterior wall by a first bolt.

[0009] Furthermore, the lower end of the Z-shaped plate, the bent end of the second bent plate and the bent end of the first bent plate respectively have through holes with the same diameter, the three through holes are connected in sequence and their axes are all located on the same straight line, and threads are provided in the three through holes, which are threadedly connected to the second bolt.

[0010] Furthermore, a third bent plate bent downward in a horizontal direction is provided at one end of the groove body away from the wall.

[0011] Furthermore, an upper end of a groove wall on a side of the groove body away from the outer wall is inclined toward a side away from the outer wall.

[0012] Furthermore, a silicone weather-resistant adhesive layer is provided on the surface of the third bending plate and the surface of the first bending plate.

[0013] Furthermore, a plurality of protrusions are arranged along the plate surface on the left side of the intercepting ditch, a plurality of depressions matching the protrusions are arranged along the plate surface on the right side of the intercepting ditch, and the rubber sealing layer is arranged on the surfaces of the protrusions and the depressions.

[0014] Furthermore, the left side plate surface of the intercepting ditch and the right side plate surface of the intercepting ditch are both provided with the rubber sealing layer.

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] The utility model provides an advanced water-stopping construction device for exterior wall thermal insulation, in which a drainage ditch is installed on the exterior wall at the top of the eaves of the main body of the floor slab that has been constructed, so as to prevent construction water and rainwater from flowing from the top of the eaves to the wall, so that the rock wool type exterior wall thermal insulation construction can be interspersed during the construction of the building body, so as to save the construction period; at the same time, the utility model uses hinges to connect the drainage ditch and the exterior wall surface, so that the drainage ditch is fully fitted with the wall surface under the action of its own gravity, so as to prevent the drainage ditch from tilting and causing water leakage; the device of the utility model also adopts a splicing structure, so that appropriate splicing can be performed according to the length of the top of the eaves of the exterior wall, and it can be used flexibly, and the rubber strips at the splicing can also effectively prevent the penetration of water flow, so as to effectively prevent waterproofing.

[0024] like Figure 1-4 As shown, the utility model provides an external wall insulation advance water-stopping construction device, including a plurality of intercepting ditches 2, each of which is fixed to the external wall eaves 1 by a hinge 3, one side of each of the intercepting ditches 2 is in contact with the external wall, each of the intercepting ditches 2 is detachably connected in sequence along its length direction, and a rubber sealing layer 6 is provided at the connection between two adjacent intercepting ditches 2.

[0025] The traditional exterior wall insulation rock wool board construction is generally horizontally pasted in order from bottom to top. After using the device provided by the utility model, since the construction is interspersed, the exterior wall insulation rock wool board construction needs to be constructed from top to bottom when the interspersed construction is carried out. During construction, the exterior wall insulation rock wool board is lifted and fixed at a suitable position on the exterior wall with a bracket, and then horizontally pasted in order from top to bottom.

[0026] The external wall eaves 1 of the utility model refers to the top of the thermal insulation rock wool board during the construction when the interlaced construction is carried out, so as to achieve the effect of water interception and water stopping.

[0027] During construction, when the main body of the building is constructed to a certain extent, the exterior wall insulation board can be pasted on the completed main body of the building. Before pasting, the device provided by the utility model is installed at the eaves 1 of the completed exterior wall, so that the intercepting ditch 2 can cover the top of the insulation rock wool board, effectively intercepting and stopping water, and preventing water from entering the insulation rock wool board. The intercepting ditch 2 is fixed to the surface of the exterior wall using the hinge 3, so that the intercepting ditch 2 is attached to the exterior wall. At the same time, according to the size of the wall, a suitable number of the devices provided by the utility model are selected and they are spliced ​​together in sequence. Since the rubber sealing layer 6 is provided at the splicing position, water seepage will not occur.

[0028] When water flows down the side wall of the exterior wall, the intercepting ditch effectively intercepts the water at the top of the rock wool insulation construction, collects and discharges it uniformly, and uses the water-stop device to form a water-breaking layer on the main body of the exterior wall, effectively preventing the top water from entering the top of the rock wool, reducing the insulation failure and secondary procurement costs caused by material soaking in water, and at the same time shortening the project construction period and reducing the operating costs during the project construction phase.

[0029] The utility model can be installed using different materials, such as PVC material, stainless steel material, etc., and the shape and size can be fine-tuned according to the construction height.

[0030] In the utility model, the intercepting ditch 2 includes a ditch body 2-1, and a first bent plate 2-3 bent downward in the horizontal direction is arranged at one end of the ditch body 2-1 close to the wall; the hinge 3 includes a Z-shaped plate 3-1 in the longitudinal direction and a second bent plate 3-2 fixed at the bottom of the Z-shaped plate 3-1, the second bent plate 3-2 is bent upward in the horizontal direction, the longitudinal section of the second bent plate 3-2 is the same in shape and size as the longitudinal section of the first bent plate 2-3 and is centrally symmetrical, and the upper end of the Z-shaped plate 3-1 is fixed to the external wall eaves 1 by a first bolt 5. In this way, the hinge 3 and the intercepting ditch 2 are hooked together, so that the intercepting ditch 2 is firmly fixed to the external wall. At the same time, the hinge 3 can also be used to adjust the left and right positions of the intercepting ditch at any time, which is very convenient during construction.

[0031] In order to make the intercepting ditch 2 more firmly fixed on the outer wall, the lower end of the Z-shaped plate 3-1, the bent end of the second bent plate 3-2 and the bent end of the first bent plate 2-3 are respectively provided with through holes of the same diameter, the three through holes are sequentially connected and their axes are all located on the same straight line, and the three through holes are provided with threads, which are threadedly connected with the second bolt 4. The second bolt 4 defines the relative position between the hinge 3 and the intercepting ditch 2.

[0032] At the same time, in the utility model, a third bent plate 2-2 bent downwardly in the horizontal direction is provided at the end of the side of the groove body 2-1 away from the wall. The upper end of the groove wall on the side of the groove body 2-1 away from the outer wall is inclined toward the side away from the outer wall. The surface of the third bent plate 2-2 and the surface of the first bent plate 2-3 are both provided with a silicone weather-resistant adhesive layer. In this way, when the water source is stored in the intercepting ditch 2, the water can be effectively intercepted, and uniformly collected and discharged, forming a water-breaking layer on the outer wall body.

[0033] In the utility model, a plurality of protrusions 7 are arranged along the board surface of the left side of the intercepting ditch 2, and a plurality of depressions 8 matching the protrusions 7 are arranged along the board surface of the right side of the intercepting ditch 2, and the surfaces of the protrusions 7 and the surfaces of the depressions 8 are both provided with the rubber sealing layer 6. The protrusions 7 and the corresponding depressions 8 are connected in a detachable manner by plugging and unplugging. After the connection, the length of the intercepting ditch 2 is extended, and the required number of intercepting ditches 2 can be selected according to the needs of the wall. At the same time, in order to increase the effect of preventing water seepage, the left board surface of the intercepting ditch 2 and the right board surface of the intercepting ditch 2 are both provided with the rubber sealing layer 6.

[0034] In summary, the device provided by the utility model installs a water cut-off device around the main body of the exterior wall, which ensures the quality of the exterior wall insulation construction while effectively interspersing the working procedures, focuses on solving the problems of exterior wall waterproof performance, economy and ease of operation, and at the same time achieves turnover and detachability for secondary utilization.

Any simple modification, change and equivalent structural change made to the above embodiments according to the technical essence of the present invention shall still fall within the protection scope of the technical solution of the present invention.
