Description
Technical Field
[0001] The utility model belongs to the technical field of thermal insulation windows, and in particular relates to a log thermal insulation passive window. Background Art
[0002] At present, the design, production and installation of wooden doors and windows are basically based on finger-jointed wood, which uses gluing technology to composite and bond various small wood blocks into wooden window materials. The advantages are that the size is not limited by the size of the material and it is not easy to deform. The disadvantages are that the structure of glued finger-jointed wood is unstable after being soaked in water for a long time, and there are hidden dangers of insufficient load-bearing performance and durability. In addition, the production cost is high and the process is complicated.
[0003] Currently, thermal insulation passive windows mostly use foreign technology and design drawings, and use aluminum-wood composites to solve various problems such as waterproofing, anti-corrosion and thermal insulation to achieve the desired effect.
[0004] Through the above analysis, the problems and defects of the existing technology are: insufficient load-bearing performance and durability; high production cost and complex process. Summary of the invention
[0005] In view of the problems existing in the prior art, the utility model provides a log thermal insulation passive window.
[0006] The utility model is implemented as follows: a log heat-insulating passive window comprises a square frame, which is composed of 4 200mm wide and 60mm thick long log squares with a mortise and tenon structure, the length of the log square is consistent with the length and width of the window hole, an L-shaped groove opened by a machine is provided in the middle of the log square, a 2cm groove is carved at the bottom, and 4-5cm is left on the outside; glass with heat-insulating performance is installed in the frame, the glass is embedded in the groove, fixed and clamped with an L-shaped stainless steel strip, and a flexible material is padded between the glass and the stainless steel.
[0007] Furthermore, a cross or T-shaped log frame may be added in the middle of the square frame.
[0008] Furthermore, the outer side of the window frame and four sides of the bottom are sprayed with a high molecular weight polyurea coating.
[0009] Furthermore, circular holes are opened at the bottom of the four sides of the window frame, and expansion bolts are driven into the holes and installed in the window holes.
[0010] Furthermore, the hole surface where the bolt meets the glass is isolated with thermal insulation foam.
[0011] Furthermore, the processed wooden board with a suitable width and a thickness of 2 cm is bound or glued to be decorated around the inner sides of the glass and the window frame.
[0012] Furthermore, sealing glass glue is applied on the inner and outer sides of the glass, and the frame is painted.
[0013] In combination with the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solutions to be protected by the utility model are as follows:
[0014] First, in view of the technical problems existing in the above-mentioned prior art and the difficulty in solving the problems, the technical solutions to be protected by the utility model and the results and data in the research and development process are closely combined to analyze in detail and deeply how the technical solutions of the utility model solve the technical problems and some creative technical effects brought about after solving the problems. The specific description is as follows:
[0015] The log structure is more water-resistant and corrosion-resistant than finger-jointed wood, and has better structural strength; the passive window structure of the utility model is simpler and the processing and production cost is lower.
[0016] The utility model does not use metal aluminum as the external structure of the wooden window, and has a lower carbon emission value than the traditional aluminum-clad wooden window, which is more environmentally friendly.
[0017] The utility model can realize on-site assembly of thermal insulation passive windows, which is beneficial to renovation projects where conditions for whole window installation are lacking.
[0018] The utility model has better thermal insulation performance and is suitable for installation in window hole reconstruction of passive houses.
[0019] The thermal insulation window of the utility model can be used in conjunction with internal thermal insulation and can achieve a connection without a thermal bridge.
[0020] Second, considering the technical solution as a whole or from the perspective of the product, the technical effects and advantages of the technical solution to be protected by the utility model are described in detail as follows:
[0021] The passive windows of the utility model all adopt wooden structure frames without metal materials such as aluminum, which can greatly improve the thermal insulation effect.
[0022] Since the passive window of the utility model has a frame thickness of 200 mm, the inwardly protruding portion can effectively cover the cross section of the inner insulation layer and can also ensure the stability of the structure fixed to the window hole.
[0023] Third, as auxiliary evidence of the inventiveness of the claims of the utility model, it is also reflected in the following important aspects:
[0024] (1) The expected profit and commercial value of the technical solution of this utility model after transformation is RMB 6 million.
[0025] (2) The technical solution of the utility model fills the technical gap in the industry at home and abroad: the present invention fills the gap in the domestic thermal insulation passive windows, which mostly combine external insulation and lack internal insulation.
[0026] (3) Whether the technical solution of the utility model solves the technical problems that people have been eager to solve but have never been able to solve: The present invention solves the problem that the thermal insulation wooden windows require metal materials such as aluminum as auxiliary materials for waterproofing and anti-corrosion on the outside, which is costly and has complex processes. It solves the design problems of passive house windows in a simple, effective and low-cost way.
[0027] (4) Whether the technical solution of the utility model overcomes the technical prejudice: The technical solution of the utility model overcomes the technical prejudice that wooden windows made of only one kind of wood without aluminum cannot be waterproof and anti-corrosion.
[0028] The present invention overcomes the technical prejudice that the overall slotting of the whole log without finger jointing and gluing may deform and crack, resulting in rough window frame craftsmanship, inaccurate precision, inability to effectively composite with aluminum materials, and inability to effectively and accurately install hardware.
