Abstract
Description
Technical Field
[0001] The utility model relates to a steel structure for an ultra-low energy consumption building, in particular to an insulating support for a metal component of an exterior wall of a low energy consumption building, which is mainly used for connecting and fixing metal components of an exterior wall of an ultra-low energy consumption (near zero carbon) building with a concrete wall, while avoiding the formation of a metal thermal bridge, not destroying the integrity of the exterior wall insulation, and ensuring the exterior wall insulation effect of the ultra-low energy consumption building to the greatest extent. Background Art
[0002] At present, ultra-low energy consumption buildings (nearly zero carbon) are being vigorously developed and are being used more and more widely. At the same time, there are more and more combinations of various steel component shapes, curtain walls and ultra-low energy consumption buildings. While enriching the exterior shapes of ultra-low energy consumption buildings, higher requirements are put forward for the quality of exterior wall insulation construction of ultra-low energy consumption buildings.
[0003] The construction of steel structure must first ensure the safety of steel components, which must have a stable connection with the concrete structure. When steel components are directly connected to the concrete wall, they will inevitably penetrate the insulation layer of the exterior wall, thereby destroying the integrity of the exterior wall insulation and affecting the energy-saving efficiency index of ultra-low energy consumption buildings. Summary of the invention
[0004] The technical problem to be solved by the utility model is to provide a low-energy consumption building exterior wall metal component heat-insulating support, which can well solve the stability problem of the direct connection and fixation of the steel component and the concrete, and can prevent the formation of a thermal bridge between the steel structure and the concrete through the heat-insulating support material, thereby ensuring the thermal insulation and energy-saving effect of the exterior wall.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:
[0006] A low-energy building exterior wall metal component insulation support, including a screw rod, which is pre-buried in a concrete wall. An insulation block and a pad pass through the screw rod in sequence and are fixed by nuts. The pad plate has a "J"-shaped shape, and the insulation block is provided with grooves corresponding to the upper and lower parts. The size of the horizontal parts at both ends of the pad plate matches the size of the grooves.
[0007] The backing plate is made of steel plate, and holes for the screw rod to pass through are opened at both ends of the backing plate.
[0008] The heat insulation block is a high-strength polyurethane heat insulation pad block, and holes for screw rods to pass through are opened on the upper and lower parts of the heat insulation block.
[0009] The outer end of the screw is located in the groove of the heat insulation block, ensuring that there is no foreign matter at the outer end of the pad, which is convenient for later welding of the exterior wall steel components.
[0010] The portion of the screw rod located in the concrete wall is limited by a fixing plate.
[0011] The utility model provides a low-energy consumption building exterior wall metal component heat insulation support, which has the following technical effects:
[0012] 1) By embedding the screw into the concrete wall, a stable connection is formed between the screw and the concrete wall, and then the thermal insulation support is installed on the screw. Finally, the external steel component and the thermal insulation support are welded to form a stable connection, and then the external steel component and the concrete wall are firmly connected through the thermal insulation support.
[0013] 2) The use of high-strength polyurethane insulation materials in the insulation support can block the heat transfer between the metal components and the concrete wall, avoid the formation of thermal bridge channels, and ensure the energy-saving and thermal insulation effect of the exterior wall.
[0014] 3) Overall, this device can not only ensure the stability of steel component installation to ensure safety, but also avoid the formation of metal thermal bridges that damage the overall thermal insulation performance of the exterior walls of low-energy buildings. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] The utility model is further described below in conjunction with the accompanying drawings and embodiments:
[0016] Figure 1 It is a top view of the utility model.
[0017] Figure 2 for Figure 1 Cross-sectional view at point a.
[0018] In the figure: pad 1, insulation block 2, nut 3, screw 4, fixing plate 5. DETAILED DESCRIPTION
[0019] like Figure 1-2 As shown, a low-energy building exterior wall metal component insulation support includes a pad 1, an insulation block 2, a fixing plate 5 and a connecting assembly.
[0020] The backing plate 1 is made of 10mm thick steel plate, and the specification model can be determined according to the size of the steel structure to be welded later. For example, the specification is 150*150mm, which is intended to be connected to 80*80mm square steel keel. The backing plate 1 is made into a "J" shape as a whole, and the middle of the bottom surface of the two ends of the "J"-shaped backing plate 1 is opened, and the hole size is slightly larger than the diameter of the screw 4.
[0021] The insulation block 2 is 50mm high-strength polyurethane, with a specification of 250*250mm (matching the specification of the steel pad). The insulation block 2 has grooves on the top and bottom, and the size of the grooves matches the size of the horizontal parts of the two ends of the "J"-shaped pad 1 to ensure a close fit.
[0022] The connection assembly includes a nut 3 and a screw rod 4. The screw rod 4 is a national standard M10 high-strength screw rod and is equipped with a corresponding nut 3. The length of the screw rod 4 is slightly less than the design thickness of the concrete wall.
[0023] A fixing plate 5 is provided in the concrete wall. The fixing plate 5 is a 3mm thick steel plate with a specification of 50*150mm. Both the upper and lower screw rods 4 can pass through the corresponding holes on the fixing plate 5 and be fixed in position. The setting of the fixing plate 5 can ensure that the upper and lower positions of the two screw rods 4 are relatively fixed, and the concrete vibration will not cause the screw rods 4 to deviate.
[0024] Working process and principle:
[0025] Step 1: A 10 mm thick steel plate is made into a "J"-shaped pad 1 as required, and holes are opened in the middle of the "J" feet at both ends.
[0026] Step 2: Carve a groove in the 50mm thick high-strength polyurethane insulation block 2 corresponding to the pad 1 area. The size of the groove matches the bottom foot of the steel pad, and a hole is opened at the corresponding position.
[0027] Step 3: Make holes at the top and bottom of the 3mm thick fixing plate 5 corresponding to the bottom holes of the pad 1 to ensure that the screw 4 can vertically pass through the fixing plate 5, the insulation block 2, and the pad 1 in sequence.
[0028] Step 4: After the concrete wall reinforcement is tied (before the template is sealed), fix the two screws 4 at the designed position and make them as firm as possible with the reinforcement. At the same time, pass the fixing plate 5 through the screws 4 to ensure that the upper and lower screws 4 are fixed in relative position. Protect the exposed threads of the screws 4.
[0029] Step 5: After the shear wall is demoulded, the insulation block 2 and the pad 1 are sequentially inserted into the pre-embedded exposed screw 4, and are tightened with the nut 3.
[0030] Step 6: After the heat insulation block 2 and the backing plate 1 are fixed by the nut 3, they form a heat insulation support as a whole. The external wall steel member can be directly welded to the backing plate 1 to achieve the fixing effect.
