Description

Technical Field

[0001] The invention relates to the technical field of construction of non-disassembly insulation boards for building exterior walls, and in particular to an anchor nail and an anchoring method. Background Art

[0002] At present, building insulation generally adopts the method of bonding EPS / XPS, rock wool, ceramic wool and other insulation materials on the exterior wall combined with anchor reinforcement. Although it has good insulation performance and effect, it also has serious problems that are difficult to overcome:

[0003] Short lifespan and poor safety. After more than ten years of construction, there are often a lot of cracks, water seepage, bulging, peeling and falling off, which pose a safety hazard of falling objects from high altitudes. The insulation part cannot have the same life cycle as the main body of the building.

[0004] Poor fireproof performance, frequent fires. Organic insulation materials such as EPS / XPS insulation boards have poor flame retardant effects, which have caused a large number of fires in practice and caused great losses.

[0005] The construction is complicated, the individual construction period is long, and the hidden costs are high.

[0006] In the past two years, some new insulation materials such as prefabricated non-disassembly insulation multi-layer composite panels or non-disassembly insulation and structural decoration integrated panels have been used as the outer casting templates, which are integrated with the main casting part, which is a great improvement over the traditional construction method. However, the composite panel itself is made of various heterogeneous materials bonded together, and often a large amount of organic materials are used for bonding or mixing. The anchoring method of the anchor in the insulation panel is still a simple mechanical penetration load-bearing method. There are still hidden dangers of long-term rain and snow invasion and separation of the bonding layer under sunlight. Its safety and fire resistance still need to be tested in long-term practice.

[0007] Inorganic insulation boards have good fire resistance, such as autoclaved aerated concrete ALC boards, which have fire resistance of A1 level, but they are heavy and difficult to anchor safely using existing construction methods.

[0008] In general, the main problems and difficulties of existing building insulation methods are that it is difficult to strike a good balance between insulation performance and fire prevention, construction cost, life cycle and structural safety. In particular, the contradiction between insulation performance and fire prevention and safety is difficult to resolve. Summary of the invention

[0009] In view of this, the purpose of the present invention is to provide an anchor and an anchoring method to achieve simultaneous anchoring of the insulation board and casting of the frame, thereby truly integrating the insulation and the frame.

[0010] While absorbing the advantages of existing new insulation materials and innovative construction methods, a higher level of rebalancing between insulation performance and fire protection, construction cost, life cycle, and insulation layer firmness should be achieved. In particular, the problem of difficult anchoring of inorganic insulation boards that are heavy but have fire protection standards of A1 should be solved.

[0011] To achieve the above object, the present invention provides the following technical solutions:

[0012] In the first aspect, the present invention provides an anchor, characterized in that it includes a shuttlecock support plate, a shuttlecock feather rod, a connecting bolt, a connecting nut, and a cast exhaust hole on the shuttlecock support plate; the connecting bolt is fixed on the shuttlecock support plate, and the shuttlecock feather rod is fixed on the connecting nut; the shuttlecock support plate can be tightened and connected to the shuttlecock feather rod through the connecting bolt and the connecting nut.

[0013] The anchor is in the shape of a shuttlecock.

[0014] The connecting bolt is vertically welded to the shuttlecock supporting piece, and the center line passes through the center of the shuttlecock supporting piece.

[0015] The shuttlecock feather rod (2) is formed by bending elbow 1 (201), bent section 1 (203), bent section 2 (204), and elbow 2 (202) in sequence, and the center lines of the bent parts of the shuttlecock feather rod (2) are in the same plane.

[0016] The bend section 1 (203) is welded on the side of the connecting nut at even intervals, and after welding, the center line of the elbow 1 (201) intersects with the center line of the connecting bolt, and the bend section 2 (204) forms an external fold angle with the center line of the connecting bolt.

[0017] In a second aspect, the present invention provides an anchoring method, characterized in that: the non-disassembly insulation board is provided with an anchoring hole, and after the shuttlecock support plate and the shuttlecock feather rod are connected and tightened in the anchoring hole, the anchoring hole and the fixed anchor nail are open to the frame casting space on the inner side, and closed but ventilated on the outer side, and the anchoring hole (7) and the non-disassembly insulation board and the ordinary template enclose an integrated casting space.

[0018] One end of the shuttlecock feather rod welded with a connecting nut is inserted through the inner side of the anchor hole and connected to a connecting bolt (3) on the shuttlecock support plate.

[0019] The diameter of the shuttlecock support piece is larger than the diameter of the anchor hole, and the shuttlecock feather rod is in the shape of a shuttlecock feather. During the tightening process, the shuttlecock support piece is fixed tightly against the outer side surface of the insulation board, or is fixed tightly against a shallow hole preset on the surface of the insulation board and adapted to the diameter of the shuttlecock support piece. The shuttlecock feather rod can be fixed by the bend section 1 (203) pressing against the inner edge of the anchor hole or the bend 2 (202) pressing against the inner side surface of the insulation board.

[0020] The distance between the center of the casting vent hole and the center of the shuttlecock support is equal to the radius of the preset anchor hole of the insulation board minus the radius of the casting vent hole. The outer edge of the casting vent hole is inscribed with the outer edge of the anchor hole, and the center of the casting vent hole is located directly above the center of the anchor hole. This ensures that during the synchronous casting process, the air in the anchor hole of the insulation board can be completely and thoroughly discharged through the casting vent hole, and it can be judged whether the anchor hole is filled with concrete mortar by observing whether the casting vent hole begins to overflow. If it does not overflow, fine sand concrete can be used for secondary reverse grouting through the casting vent hole later.

[0021] By adjusting the size of the outer folding angle when the shuttlecock feather rod is bent, the pressing point of the shuttlecock feather rod body on the inner wall edge of the preset anchor hole of the insulation board is adjusted, and the length ratio of the shuttlecock feather rod in the anchor hole and the cast-in-place concrete is distributed.

[0022] The shape, fixing position and fixing method of the shuttlecock feather rod are adjusted by adjusting the lengths of the elbow one (201), the elbow two (202), the bend section one (203) and the bend section two (204), the bending angle within the range of 0-180°, and the welding position of the bend section one (203).

[0023] The anchoring volume and anchoring capacity of the anchor can be adjusted by adjusting the manufacturing dimensions of the shuttlecock support piece and the shuttlecock feather rod.

[0024] The anchor or the method is a part of the casting formwork so as to avoid dismantling the insulation board. The anchor anchors the insulation board by casting in situ and is implemented simultaneously with the casting of the frame. The structure realized by the anchoring method penetrates the frame and the insulation board and is anchored in an integrated manner.

[0025] The beneficial effect of the present invention is that the anchor nails described in the present invention realize the simultaneous anchoring of the insulation board and the casting of the building frame through the above technical scheme. The insulation board and the frame penetrate into each other, are integrally formed, and are firmly anchored together, which completely solves the problem of the insulation layer falling off. It is especially suitable for the construction of insulation boards with heavier weight, and better takes into account the simultaneous realization of building insulation, fire protection and safety.

[0042] The following will be combined with the drawings of the preferred embodiments of the specific implementation of the present invention to clearly and completely describe the technical solution of the present invention. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can completely combine the embodiments of the present invention to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0043] The following example uses 100mm thick B04 autoclaved aerated concrete panels as non-dismantling insulation formwork to implement insulation panel anchoring and simultaneous cast-in-place frame.

[0044] [Preferred embodiment 1]

[0045] like Figure 1 and Figure 4As shown, an anchor nail for realizing anchoring and pouring synchronously comprises a shuttlecock support piece (1), a shuttlecock feather rod (2), a connecting bolt (3), a connecting nut (4) and a pouring exhaust hole (5) on the shuttlecock support piece (1); the connecting bolt (3) is fixed on the shuttlecock support piece (1), and the shuttlecock feather rod (2) is fixed on the connecting nut (4); the shuttlecock support piece (1) can be connected to the shuttlecock feather rod (2) by tightening the connecting bolt (3) and the connecting nut (4).

[0046] The anchor manufacturing method:

[0047] Step 101: Select a hexagonal connecting nut (4) with an inner diameter of 8 mm and an outer diameter of 17 mm, and a matching connecting bolt (3) for use.

[0048] Step 102: Figure 1 As shown, the shuttlecock support plate (1) is a galvanized round iron plate with a diameter of 8 cm and a thickness of 2 mm (the thickness can be adjusted as needed in actual production). A casting exhaust hole (5) with a diameter of 5 mm is drilled at a position 27.5 mm away from the center of the shuttlecock support plate (1) to exhaust air during casting and verify whether the anchor hole (7) is filled with concrete mortar.

[0049] Step 103: Figure 1 As shown, the head of the connecting bolt (3) is welded to the shuttlecock support piece (1), and the center line of the connecting bolt (3) passes through the center of the shuttlecock support piece (1) and is perpendicular to the shuttlecock support piece (1).

[0050] Step 104: Figure 1 As shown, the shuttlecock feather rod (2) is formed by bending a 19 cm long round steel bar segment with a diameter of 6 mm. One end of the round steel bar segment is bent 90° for 2 cm to form a bend 1 (201), and 11° is bent at a position 10 mm away from the bend 1 (201) to form a 10 mm bend 1 (203). The other end of the round steel bar segment is bent 2 cm to form a bend 2 (202) and a bend 2 (204). The bend 2 (202) and the bend 2 (204) form an angle of 56 degrees, and the bending center lines of the bend 1 (201), the bend 2 (202), the bend 1 (203) and the bend 2 (204) are in the same plane.

[0051] Step 105: Figure 1 As shown, the bend section 1 (203) on the shuttlecock rod (2) is welded evenly and flushly on the side of the connecting nut (4). After welding, the center line of the elbow 1 (201) intersects with the center line of the connecting bolt (3), and the bend section 2 (204) forms an outer fold angle (6) with the center line of the connecting bolt (3). The outer edge of the round steel bar of the bend section 1 (203) is 6mm+17mm / 2=14.5mm away from the center of the nut.

[0052] Since the above steps have completed the production of the shuttlecock-shaped anchor device, the following are the methods and steps for installing the anchor to achieve synchronous cast-in-place:

[0053] Step 106: In this embodiment 1, ALC plate of model B04 is selected for supporting construction, with a thickness of 100 mm, a width of 600 mm, and a height of 3000 mm. The plate thickness and model selection can be adjusted according to national building insulation standards and construction requirements.

[0054] Step 107: Use the ALC board as the outer non-removable template to complete the initial installation of the template.

[0055] Step 108: During the template installation process, before the large-scale installation of square wood and wire drawing, a through anchor hole (7) with a diameter of 6 cm is drilled at the intersection of the ALC board 4 cm away from the horizontal and vertical reinforcements. Figure 6 As shown, the number depends on the construction requirements and standard operation (this embodiment is implemented with 6 anchors). The shuttlecock feather rod (2) is inserted into the anchor hole (such as Figure 6 As shown), the shuttlecock support plate (1) is connected and tightened together through the connecting bolt (3) and the connecting nut (4), and the casting exhaust hole (5) is located at the upper center of the anchor hole. During the tightening process, the shuttlecock feather rod (2) is pressed against the inner edge of the anchor hole (7) and fixed at a distance of (30mm-14.5mm)×tan79°≈15.5×5.1446=79.7mm from the welding point between the connecting nut (4) and the shuttlecock feather rod (2). At this time, the shuttlecock feather rod (2) can penetrate into the reinforced concrete for a portion of:

[0056] 190mm-20mm-10mm-79.7mm≈71.3mm

[0057] The second elbow (202) is 20mm deep, and the directly penetrating part is 50mm. The shuttlecock support piece (1) is fixed closely to the outer side of the ALC board. If necessary, the shuttlecock feather rod (2) can be tied together with the frame steel bar.

[0058] Step 109: Install the square timber, steel pipe and wire drawing to complete the formwork. When installing the square timber, steel pipe and wire drawing, avoid covering the casting exhaust hole (5). At this time, the fixed anchor nails and the anchor holes (7) form an inner side open to the frame casting space, and the outer side is closed but ventilated, so that a synchronous cast-in-place structure can be realized. The anchor holes (7) where the anchor nails are installed, the insulation board, and other templates together form an insulation board anchoring and frame synchronous cast-in-place system.

[0059] Step 110: pouring concrete. When pouring reinforced concrete, the pouring vent holes (5) should be observed to see if they are overflowing. If overflowing begins, they should be blocked with small wooden wedges. After the formwork is removed, the pouring vent holes (5) should be carefully checked one by one, and the blocking small wooden wedges should be removed. If there is no overflow, fine sand concrete should be used to grout the pouring vent holes (5) for a second time to avoid incomplete grouting of the anchor holes (7).

[0060] Step 111: Secondary structure masonry. To ensure that the insulation construction meets the national insulation and energy-saving standards and customer requirements, this embodiment should be combined with the selection of secondary structure masonry methods. 300mm thick self-insulating aerated blocks or 300mm thick self-insulating ALC panels should be selected for secondary structure masonry. During masonry, the hollow part should be flush with the installed 100mm thick ALC panels.

[0061] Step 112: Subsequent construction procedures are carried out according to construction requirements.

[0062] [Preferred embodiment 2]

[0063] Step 201: Select a hexagonal connecting nut (4) with an inner diameter of 8 mm and an outer diameter of 17 mm, and a matching connecting bolt (3), wherein the matching connecting bolt (3) has a length of not less than 16 cm and a threaded portion length of not less than 14 cm, and set aside for use.

[0064] Step 202: Same as Example 1.

[0065] Step 203: Same as Example 1.

[0066] Step 204: Figure 2 As shown, the shuttlecock feather rod (2) is formed by bending a 25 cm long round steel bar segment with a diameter of 6 mm. One end of the round steel bar segment is bent 90° for 2 cm to form a first elbow (201), and 13 cm away from the first elbow (201) is bent 90° to form a first bent segment (203) of 13 cm. The other end of the round steel bar segment is bent 90° to form a second elbow (202) of 6 cm and a second bent segment (204) of 4 cm. Each adjacent part of the shuttlecock feather rod (2) is at an angle of 90°, and the bending center lines of the first elbow (201), the second elbow (202), the first bent segment (203), and the second bent segment (204) are in the same plane.

[0067] Step 205: Figure 2 As shown, the middle section of the bend section 1 (203) on the shuttlecock rod (2) is evenly and flushly welded to the side of the connecting nut (4) at a distance of 50 mm from the elbow 1 (210). After welding, the center line of the elbow 1 (201) intersects with the center line of the connecting bolt (3).

[0068] Step 106 and step 107 are the same as in the preferred embodiment 1.

[0069] Step 108: The difference from the preferred embodiment 1 is that during the tightening process, the elbow (202) on the shuttlecock rod (2) touches the inner side of the anchor hole and is fixed (such as Figure 6 As shown), at this time, the shuttlecock feather rod (2) can penetrate 6 cm into the reinforced concrete, and the connecting bolt (3) can penetrate 6 cm into the reinforced concrete. If necessary, the shuttlecock feather rod (2) and the connecting bolt (3) can be tied together with the frame reinforcement.

[0070] The subsequent steps are the same as those in the preferred embodiment 1.

[0071] [Preferred embodiment 3]

[0072] Step 301: Same as Example 2.

[0073] Step 302 and step 303 are the same as those in embodiments 1 and 2.

[0074] Step 304: Figure 3 As shown, the difference is that the shuttlecock feather rod (2) is formed by bending a 20 cm long round steel bar segment, and the bent segment 1 (203) is changed to 8 cm long and does not penetrate into the anchor hole.

[0075] Step 305, step 306, step 307, step 308 and subsequent steps are the same as those in preferred embodiment 2.

[0076] Analysis of the firmness of the embodiments of the present invention:

[0077] At present, the grade of reinforced concrete used in construction is generally C25, C30 or C35, among which the standard value of compressive strength of C25 is 25MPa and the standard value of tensile strength is 1.78MPa. The present invention does not elaborate on the firmness of the part where the anchor penetrates into the concrete, but only analyzes the anchoring capacity of the ALC plate part. According to national standards, the strength of the B04 plate is not less than 2.5MPa. One anchor forms a reinforced concrete cylinder with a diameter of 6cm and a length of 10cm in the ALC plate.

[0078] In the vertical direction, the support force provided by the reinforced concrete cylinder with a diameter of 6 cm and a length of 10 cm on the ALC plate is:

[0079] 2.5×1000000×π×6 / 2×10÷10000=23561N≈2356kgf;

[0080] Therefore, in the vertical direction, the supporting force provided by one anchor is about 2356 kg, and the supporting force provided by 6 anchors is about 2356×6=14136 kg. The maximum weight of an ALC panel with a height of 3000 mm, a width of 600 mm and a thickness of 100 mm is only 81 kg. In the exposed state, the maximum weight after rainwater penetration will not exceed 260 kg. The supporting force is more than 54 times the maximum weight, and this does not take into account the bonding force formed between the panel and the concrete casting part.

[0081] In the horizontal direction, one anchor covers the area of ​​the ALC sheet with a diameter of 8 cm, and the fixing pressure is:

[0082] 2.5×1000000×π×42÷10000=12566 Newtons≈1256 kilograms of force

[0083] Therefore, in the horizontal direction, the fixing force provided by one anchor is about 1256 kg, and the fixing force provided by 6 anchors is about 1256×6=7536 kg. The area of ​​an ALC board is 1.8㎡, and the force that can be withstood per square meter is: 7536÷1.8=4186 kg.

[0084] Force calculation under 12-level typhoon:

[0085] Wind speed range: The wind speed range of a level 12 typhoon is 32.7 to 36.9 meters per second.

[0086] Wind pressure formula: According to the formula P = kv 2 , the wind pressure can be calculated. Among them, P represents wind pressure, k represents air density, and v represents wind speed. Under the condition of standard atmospheric pressure of 1000 hPa (1000 mb), the force per square meter on the front of a level 12 typhoon is approximately between 1069 and 1361 kg. The fixing pressure is about 3.075-3.915 times the wind force. It also does not take into account the bonding force formed between the plate and the cast part, and it is very convenient to increase the anchoring capacity and safety factor by increasing the number of anchors per unit area.

[0087] Data proves that the present invention has a high anchoring safety factor in both vertical and horizontal directions.

[0088] The preferred embodiments of the present invention disclosed above are only used to help explain the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well. The present invention is limited only by the claims and their full scope and equivalents.
