Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a passive building exterior wall scaffolding wall connecting piece and a construction method thereof. Background Art

[0002] Wall ties are components that connect the scaffolding frame to the main structure of the building and can transmit tension and pressure, and mainly play a role of rigid connection. At present, the most widely used wall ties in the existing technology are the pre-buried steel pipe method and the assembled wall ties.

[0003] As for the method of using pre-buried steel pipes, although this method can meet the rigid connection function of the wall connection parts, the disadvantages of this method are that it has high construction cost, great construction difficulty, troublesome disassembly, small force, great hidden dangers, easy to break, and long construction process, and the quality of the house wall will be affected by its shortcomings. In addition, pre-buried steel pipes will cause cold bridges on the exterior walls of buildings, affecting the energy-saving effect of the building walls.

[0004] For the method of using assembled wall connections, this approach requires the customization of special scaffolding fasteners, sleeves, screws, nuts, etc. for on-site pre-embedding, which not only increases the construction cost and construction process, but also requires additional customization of special sleeves and other construction materials for the exterior walls of different building structures. It can be seen that this approach has poor adaptability.

[0005] In addition, the above two widely used wall ties are applicable to ordinary building exterior walls, and there is no wall tie method applicable to passive building exterior walls, and there is still a lack of special construction methods for wall ties that can avoid the generation of cold and hot bridges on passive building exterior walls. Therefore, there is an urgent need for a wall tie that can be applied to passive building exterior walls and can solve the problem of cold and hot bridges, while also having low construction difficulty and low cost.

[0048] See again Figure 1 as well as Figure 2The passive building exterior wall scaffolding wall connection member provided by the embodiment of the present invention includes an insulation integrated wall 100, a through-wall bolt 200, a connection assembly 300, a tension assembly 400, a steel pipe 500 and a scaffolding assembly 600; the through-wall bolt 200 is penetrated through a preset tension screw hole inside the insulation integrated wall 100, one end of which is connected to the steel pipe 500 through the connection assembly 300, and the other end is connected to the tension assembly 400; the steel pipe 500 is connected to the scaffolding assembly 600 through the connection assembly 300; the end of the steel pipe 500 on one side connected to the through-wall bolt 200 is in contact with the exterior wall panel on the surface of the insulation integrated wall 100.

[0049] In this embodiment, the passive building exterior wall adopts an insulation integrated wall 100, and an insulation integrated wall panel 700 is arranged on the surface of the insulation integrated wall 100. The insulation integrated wall panel includes an outer wall panel 710 and an inner wall panel 720, wherein the outer wall panel 710 is arranged on the surface of one side of the insulation integrated wall 100, and the inner wall panel 720 is arranged on the surface of the other side of the insulation integrated wall 100. The insulation integrated wall 100 includes a self-compacting concrete protective layer 110, a graphite polystyrene board 120, and a self-compacting concrete structural layer 130, and the self-compacting concrete protective layer 110 and the self-compacting concrete structural layer 130 are respectively arranged on both sides of the graphite polystyrene board 120. That is, the insulation integrated wall 100 is composed of three structural layers of the self-compacting concrete protective layer 110, the graphite polystyrene board 120, and the self-compacting concrete structural layer 130.

[0050] During construction, the wall ties suitable for passive building exterior walls need to pass through the tension screw holes set in the thermal insulation integrated wall panels 700 and the thermal insulation integrated wall body 100 during the concrete process, with the inner self-compacting concrete structure layer 130 serving as the main load-bearing member to support the wall ties.

[0051] Specifically, the self-compacting concrete protective layer 110 is arranged between the inner surface of the outer wall panel 710 and the graphite polystyrene board 120, and the self-compacting concrete structural layer 130 is arranged between the graphite polystyrene board 120 and the inner surface of the inner wall panel 720. One end of the through-wall bolt 200 located on the outer surface of the outer wall panel 710 is fixedly connected to one end of the steel pipe 500 through the connecting assembly 300, and the other end of the steel pipe 500 is fixedly connected to the scaffolding assembly 600 through the connecting assembly 300; one end of the through-wall bolt 200 located on the outer surface of the inner wall panel 720 is connected to the tensile assembly 400 to prevent it from moving toward the outer wall panel 710. By making full use of the tension screw holes of the thermal insulation integrated wall 100 in the concrete process without the need for additional reserved holes and reserved steel embedded parts, the problem of the pre-embedded embedded parts being offset during the concrete pouring process, resulting in the inability to install the wall connection parts, is avoided, and the cold and hot bridges and construction procedures are reduced.

[0052] In addition, the end of the steel pipe 500 connected to the through-wall bolt 200 abuts against the exterior wall panel 710 on the surface of the thermal insulation integrated wall 100, which helps to increase the connection strength between the scaffolding and the thermal insulation integrated wall 100, thereby improving the stability of the entire structure of the scaffolding and the wall connection parts.

[0053] In one embodiment, if Figure 2 As shown, the connection assembly 300 includes a first fastener 310, a fastener fixing nut 320, a fastener fixing bolt 330 and a tie rod fixing nut 340; the steel pipe 500 and the through-wall bolt 200 both vertically penetrate the first fastener 310, wherein the steel pipe 500 is parallel to the through-wall bolt 200 and is located above the through-wall bolt 200; the tie rod fixing nut 340 is sleeved on the through-wall bolt 200, and is located between the first fastener 310 and the thermal insulation integrated wall 100;

[0054] The fastener fixing bolt 330 is arranged inside the first fastener 310 and is perpendicular to the steel pipe 500 and the through-wall bolt 200, and is used to fix the steel pipe 500 and the through-wall bolt 200 to the first fastener 310; the fastener fixing nut 320 is sleeved on the connecting part of the fastener fixing bolt 330, and the connecting part is the part of the fastener fixing bolt 330 located outside the first fastener 310.

[0055] In this embodiment, first, after aligning the steel pipe 500 and the through-wall bolt 200 with the holes on the first fastener 310 respectively, they are successively passed through the corresponding holes on the first fastener 310 to vertically penetrate the first fastener 310, wherein the steel pipe 500 is parallel to the through-wall bolt 200 and is located above the through-wall bolt 200. The relative position of the steel pipe 500 and the through-wall bolt 200 is ensured to be stable, which provides a basis for subsequent connection work. In addition, the layout of the steel pipe 500 being parallel to the through-wall bolt 200 and located above it is conducive to dispersing the force and enhancing the stability of the wall connection structure. Secondly, the tie rod fixing nut 340 is sleeved on the through-wall bolt 200, and it is ensured to be located between the first fastener 310 and the outer wall panel 710 of the thermal insulation integrated wall 100. At this time, the construction personnel need to use construction tools to tighten the tie rod fixing nut 340 until it fits with the outer surface of the outer wall panel 710 to ensure the firmness of the connection. Pre-tightening the through-wall bolt 200 by means of the pull rod fixing nut 340 helps to enhance the close connection between the wall and the connecting assembly 300 and improve the overall stability.

[0056] Then, the fastener fixing bolt 330 is screwed vertically from the top of the first fastener 310 into the interior using a construction tool (e.g., a wrench) until it is in close contact with the steel pipe 500 and the through-wall bolt 200. The function of the fastener fixing bolt 330 is to firmly fix the steel pipe 500 and the through-wall bolt 200 on the first fastener 310 to form a stable connection structure, thereby tightly fixing the steel pipe 500 and the through-wall bolt 200 on the first fastener 310. Finally, the fastener fixing nut 320 is sleeved on the connection portion of the fastener fixing bolt 330 and screwed until it fits the surface of the first fastener 310. By tightening the fastener fixing nut 320 on the connection portion of the fastener fixing bolt 330, the connection between the steel pipe 500, the through-wall bolt 200 and the first fastener 310 can be further consolidated, ensuring the reliability and safety of the entire connection assembly 300.

[0057] In addition, in the embodiment of the present application, the connection assembly 300 further includes a thread (not shown in the figure), which is sleeved on the through-wall bolt 200 and matched with the tie rod fixing nut 340. Specifically, in the actual construction process, for the walls of the passive building exterior walls of different thicknesses, comprehensive adjustments can be made by adjusting the length of the through-wall screw, the length of the thread (the total length of the thread is 300 mm) and the position of the tie rod fixing nut 340 to achieve the exterior wall connection construction for different wall thicknesses.

[0058] In one embodiment, if Figure 2 As shown, the tensile component 400 includes a tensile gasket 410, a tensile fixing nut 420 and a reverse tensile fixing nut 430; the first fastener 310 is arranged between the reverse tensile fixing nut 430 and the pull rod fixing nut 340; the tensile fixing nut 420 and the reverse tensile fixing nut 430 are both sleeved on the through-wall bolt 200, wherein the reverse tensile fixing nut 430 is arranged at one end of the through-wall bolt 200 connected to the first fastener 310, and the tensile fixing nut 420 is arranged at the other end of the through-wall bolt 200; the tensile gasket 410 is arranged between the tensile fixing nut 420 and the inner wall surface of the thermal insulation integrated wall 100.

[0059] In this embodiment, the reverse tensile fixing nut 430 is sleeved on the through-wall bolt 200 and is located on one side of the first fastener 310. When the through-wall bolt 200 is subjected to a pulling force toward the outer wall panel 710, the reverse tensile fixing nut 430 can provide a reverse resistance through the connection of the first fastener 310, effectively resisting and dispersing the pulling force, and preventing the thermal insulation integrated wall 100 from moving outward or deforming. The tensile fixing nut 420 is sleeved on the through-wall bolt 200 and is located on the side facing the inner wall panel 720. As the fixing point of the other end of the through-wall bolt 200, it works in conjunction with the reverse tensile fixing nut 430 to form a stable tensile balance system, ensuring the stability of the entire thermal insulation integrated wall 100 structure construction.

[0060] By setting the first fastener 310 between the reverse tensile fixing nut 430 and the pull rod fixing nut 340, not only the strength of the connection between the steel pipe 500 and the through-wall bolt 200 is enhanced, but also the force on the entire tensile assembly 400 is made more uniform, avoiding local stress concentration, and improving the overall stability and bearing capacity of the entire scaffolding and wall connection parts.

[0061] In one embodiment, if Figure 1 As shown, the scaffolding assembly 600 includes a plurality of vertical poles 610, a plurality of horizontal poles 620 and a plurality of diagonal poles 630; the plurality of vertical poles 610 are fixedly connected by a first connecting member to form a first vertical pole and a second vertical pole of equal height; the first vertical pole and the second vertical pole are both perpendicular to the ground, and the top ends of the first vertical pole and the second vertical pole are both connected to the building beams by a second connecting member;

[0062] The plurality of cross bars 620 are arranged at equal intervals between the first vertical bar and the second vertical bar, wherein the left ends of the plurality of cross bars 620 are fixedly connected to the first vertical bar via a third connecting member, and the right ends of the plurality of cross bars 620 are fixedly connected to the second vertical bar via a third connecting member; one end of the plurality of diagonal bars 630 is connected to the left ends of the plurality of cross bars 620, and the other end of the plurality of diagonal bars 630 is connected to the right ends of the plurality of cross bars 620.

[0063] In this embodiment, the installation steps of the scaffolding assembly 600 are as follows: First, a plurality of vertical poles 610 are fixedly connected using a first connecting member to form a plurality of vertical poles of equal height, namely, a plurality of first vertical poles and a plurality of second vertical poles. Ensure that the two vertical poles are perpendicular to the ground to provide a stable support for the scaffolding and prevent safety accidents caused by tilting or shaking during the construction process.

[0064] The second step is to use the second connecting piece to connect the top of the first vertical pole and the second vertical pole to the building beam respectively, thereby ensuring the stable connection between the scaffolding and the main structure of the building, so that the scaffolding can bear a larger load and improve the safety during the construction process.

[0065] The third step is to set a plurality of crossbars 620 in order from bottom to top at equal intervals between the first vertical pole and the second vertical pole. In specific operation, the left end of the crossbar 620 is fixedly connected to the first vertical pole using the third connecting member, and the right end of the crossbar 620 is fixedly connected to the second vertical pole, thereby forming a horizontal support structure of the scaffold. The setting of the crossbar 620 can enhance the lateral stability of the scaffold and prevent structural deformation or collapse caused by external forces.

[0066] The fourth step is to install the diagonal rod 630 to enhance the stability of the scaffold. Connect one end of the diagonal rod 630 to the left end of the cross bar 620, and the other end to the right end of the cross bar 620 of the previous layer. For example, assuming that the cross bar 620 of the bottom layer is the first layer, one end of the first diagonal rod 630 is connected to the left end of the cross bar 620 of the first layer, and the other end of the first diagonal rod 630 is connected to the right end of the cross bar 620 of the second layer; one end of the second diagonal rod 630 is connected to the left end of the cross bar 620 of the second layer, and the other end of the second diagonal rod 630 is connected to the right end of the cross bar 620 of the third layer; and so on and so forth in the same manner until the diagonal rod 630 is connected to the cross bar 620 of the top layer.

[0067] The overall structure of the scaffolding is further strengthened through the support of the diagonal rods 630. At the same time, the addition of the diagonal rods 630 can form a triangular support structure, thereby improving the scaffolding's anti-overturning ability, improving the overall safety and stability of the scaffolding, and also providing strong support and protection for the safety of construction workers.

[0068] There is no limit to the number of the first vertical pole and the second vertical pole, which can be set according to the construction requirements during specific implementation. During specific implementation, the step distance and span between the first vertical pole, the second vertical pole and the cross bar 620 are generally greater than 1.2 meters, and the horizontal spacing of the tension screws of the external wall formwork of the thermal insulation integrated wall 100 is set between 0.5 meters and 0.6 meters. After determining the diameter of the tension screws by calculation, in order to ensure the permanent connection of the holes, the spacing of the scaffolding wall parts can be reduced to ensure that the force of the wall parts meets the construction requirements. This method can not only adapt to different external wall screw diameters but also adapt to external wall systems with different spacings, so it has good adaptability.

[0069] In one embodiment, if Figure 1As shown, the passive building exterior wall scaffolding wall connection member also includes a protective frame 800, and the protective frame 800 is fixedly connected to a plurality of cross bars 620. Specifically, the height of the protective frame 800 is set as needed. One end of the cross bar 620 is fixedly connected to the first vertical pole, and the other end is fixedly connected to the protective frame 800. A plurality of cross bars 620 are arranged between the protective frame 800 and the first vertical pole, and an inclined rod 630 is arranged between each two adjacent cross bars 620, one end of the inclined rod 630 is connected to the right end of the cross bar 620, and the other end is connected to the left end of the adjacent cross bar 620 of the upper layer of the aforementioned cross bar 620. That is, the cross bar 620 and the inclined rod 630 between the protective frame 800 and the first vertical pole are respectively symmetrical with the cross bar 620 and the inclined rod 630 between the first vertical pole and the second vertical pole, with the first vertical pole as the symmetry axis.

[0070] In one embodiment, if Figure 1 As shown, the connection assembly 300 further includes a second fastener 350 ; the steel pipe 500 is fixedly connected to the first upright pole and the second upright pole through the second fastener 350 .

[0071] In this embodiment, the steel pipe 500 is fixedly connected to the first vertical pole and the second vertical pole by the second fastener 350, which not only allows the scaffolding and the wall connecting parts to be tightly connected together to form a more stable overall structure, but also can give play to the inherent advantages of the steel pipe 500 such as high strength, high hardness and good compressive performance, thereby giving full play to the carrying capacity of the steel pipe 500, ensuring that the scaffolding can withstand its own weight and various loads during the construction process, thereby ensuring construction safety.

[0072] In one embodiment, if Figure 1 As shown, the length of the through-wall bolt 200 is greater than the thickness of the thermal insulation integrated wall 100 ; the diameter of the through-wall bolt 200 is smaller than the diameter of the tension screw hole preset inside the thermal insulation integrated wall 100 .

[0073] In this embodiment, the diameter of the tension screw hole can be set between 12 mm and 16 mm as needed during specific implementation. For example, assuming that the diameter of the tension screw hole is 14 mm, the diameter of the through-wall bolt 200 needs to be less than 14 mm to facilitate passing the through-wall bolt 200 through the tension screw hole. In addition, since the length of the through-wall bolt 200 is greater than the thickness of the thermal insulation integrated wall 100, the through-wall bolt 200 can completely penetrate the thermal insulation integrated wall 100, so that the wall connecting parts can apply sufficient tightening force during the installation process to ensure the stability and safety of the connection. At the same time, since the length of the through-wall bolt 200 is greater than the thickness of the thermal insulation integrated wall 100, there is room for adjustment to meet construction requirements. It should be noted that the diameter of the tension screw hole is not specifically limited in the embodiment of the present application, and is only used to illustrate it.

[0074] like Figure 3 As shown, an embodiment of the present invention further provides a construction method for a passive building exterior wall scaffolding wall connection member, which is applied to the passive building exterior wall scaffolding wall connection member in any of the aforementioned embodiments, and the method includes the following steps S110-S130.

[0075] S110 , pouring concrete for the thermal insulation integrated wall 100 , and presetting tension screw holes in the thermal insulation integrated wall 100 .

[0076] In this embodiment, during the concrete pouring of the thermal insulation integrated wall 100, it is necessary to ensure that the concrete is poured evenly without voids or bubbles, so as to ensure the density and strength of the thermal insulation integrated wall 100. At the same time, the tension screw holes are preset in the thermal insulation integrated wall 100, and the diameter, position and depth of the tension screw holes must be strictly carried out in accordance with the design drawings and construction requirements, so that the subsequent through-wall bolts 200 can be accurately and firmly penetrated without the need to add additional holes for penetrating the tension screws.

[0077] In addition, when inserting the through-wall bolt 200 into the preset tension screw hole, the selection of the through-wall bolt 200 must comply with industry standards. Specifically, its length should be greater than the thickness of the thermal insulation integrated wall 100, and its diameter should be slightly smaller than the diameter of the tension screw hole, so as to facilitate insertion and tightening. During the insertion process, it is necessary to ensure that the bolt is vertical and not skewed, and use a special tool (for example, a wrench) to tighten the tension fixing nut 420 and the reverse tension fixing nut 430 to the torque value or position required by the design to ensure the overall stability and reliability of the wall connection.

[0078] S120, insert the through-wall bolt 200 into the preset tension screw hole, connect one end of the through-wall bolt 200 to the tension component 400, connect the other end to the steel pipe 500 and fix the steel pipe 500 to the scaffolding component 600, and complete the installation of the wall connection member.

[0079] The tensile assembly 400 is usually made of high-strength steel and has excellent tensile properties. Specifically, when connecting the through-wall bolt 200 and the tensile assembly 400, a tensile gasket 410, a tensile fixing nut 420 and a reverse tensile fixing nut 430 are used. The tensile gasket 410 is located between the inner wall panel 720 and the tensile fixing nut 420. A special tool is used to tighten the tensile fixing nut 420 and the reverse tensile fixing nut 430 to ensure that the through-wall screw is firm and not loose. The diameter, wall thickness and length of the steel pipe 500 can be selected according to different construction requirements to ensure its bearing capacity and stability. When fixing, fasteners and other connectors are used to ensure that the steel pipe 500 and the scaffolding assembly 600 can be tightly and firmly connected.

[0080] S130, dismantle the scaffolding assembly 600 and pull out the through-wall bolts 200.

[0081] After the scaffolding assembly 600 is dismantled in order according to the construction steps and the through-wall bolts 200 are pulled out, the tie screw holes are blocked according to the requirements for blocking tie screw holes in passive buildings.

[0082] In one embodiment, if Figure 4 As shown, S110 includes the following steps:

[0083] S1101. The integrated structural walls of the building under construction shall be bound with steel bars.

[0084] In this embodiment, it is necessary to ensure that the specifications, spacing and lap length of the steel bars meet the design requirements of the specific construction to form a stable steel skeleton. The embodiment of the present application does not make specific requirements on the specifications, spacing and lap length of the steel bars, and can be set accordingly according to different construction requirements. The use of steel bars for fine binding of the integrated structural wall of the construction building can not only enhance the overall structural strength of the thermal insulation integrated wall 100, but also provide reliable support for subsequent concrete pouring, ensuring that the thermal insulation integrated wall 100 will not crack or deform.

[0085] S1102. Support and install the insulation board and the wooden formwork with pre-set through holes.

[0086] In this embodiment, the selection of the insulation board must meet the energy-saving standards, and its installation should be flat and firm to ensure the insulation performance of the thermal insulation integrated wall 100. The through holes of the wooden template must be accurately reserved, corresponding to the positions of the subsequent tension screw holes, which is conducive to the accurate positioning and fixing of the wooden template, while reducing the risk of leakage during concrete pouring.

[0087] S1103, according to the through holes on the wooden formwork, preset tension screw holes in the thermal insulation integrated wall 100 corresponding to the through holes, and insert tension screws into the preset tension screw holes.

[0088] In this embodiment, the tension screw holes preset during concrete pouring can, on the one hand, effectively connect the wooden formwork and the thermal insulation integrated wall 100. By inserting the tension screws, the wooden formwork can be tightened and fixed, thereby preventing the wooden formwork from being displaced or deformed during the concrete pouring process. On the other hand, when the through-wall bolts 200 are subsequently installed, there is no need to add additional holes, and the tension screw holes can be directly fully utilized, which greatly simplifies the construction process and reduces the construction cost. At the same time, there is no need to pre-embed metal embedded parts, which effectively avoids the problem of cold and hot bridges in the thermal insulation integrated wall 100.

[0089] S1104. After the overall reinforcement is completed, concrete pouring is carried out.

[0090] S1105. When the concrete strength reaches the requirement, remove the wooden formwork and the tension screws.

[0091] In one embodiment, if Figure 5 As shown, S120 includes the following steps:

[0092] S1201, using the preset tension screw hole to penetrate the through-wall bolt 200, and sequentially sleeve the tension-resistant gasket 410 and the tension-resistant fixing nut 420 on the through-wall bolt 200.

[0093] Specifically, the wall connecting member in the embodiment of the present application can be applicable to different thicknesses of the thermal insulation integrated wall 100, wherein the diameter of the through-wall bolt 200 is between 12 mm and 16 mm, the diameter of the tension screw hole is 2 mm larger than the diameter of the through-wall bolt 200, and the length of the through-wall screw is 200 mm longer than the wall thickness of the thermal insulation integrated wall 100. For example, assuming that the diameter of the tension screw hole is 16 mm and the wall thickness of the thermal insulation integrated wall 100 is 100 mm, the diameter of the through-wall bolt 200 is 14 mm, and the length of the through-wall bolt 200 is 300 mm. It should be noted that the present application does not impose specific restrictions on the length and diameter of the through-wall bolt 200, but can be set according to actual construction needs. Since the length of the through-wall bolt 200 is greater than the thickness of the thermal insulation integrated wall 100 and its diameter is smaller than the diameter of the tension screw hole, for passive thermal insulation integrated walls 100 of different thicknesses, the thermal insulation integrated walls of different thicknesses can be connected to each other by comprehensively adjusting the length of the through-wall screw, the thread length of the through-wall screw and the position of the tension rod fixing nut 340.

[0094] When inserting the through-wall bolt 200 into the tension screw hole, it is necessary to ensure that the diameter of the through-wall bolt 200 matches the tension screw hole, which not only helps the bolt to be inserted smoothly, but also ensures the stability of the connection part, which is the first step in the installation of the wall connection. Subsequently, the tension-resistant gasket 410 and the tension-resistant fixing nut 420 are sequentially sleeved on the through-wall bolt 200 at the end of the through-wall bolt 200 facing the inner wall plate. The tension resistance of the through-wall bolt 200 is effectively enhanced by sleeve-mounting the tension-resistant gasket 410 and the tension-resistant fixing nut 420. The end of the through-wall bolt 200 facing the outer wall plate 710 is connected to the steel pipe 500 through the first fastener 310. Therefore, in order to ensure that the wall connection can be stably connected, the tension-resistant gasket 410 and the tie rod fixing nut 340 need to be sleeved on the through-wall bolt 200 first to prevent the through-wall bolt 200 from moving due to external force, thereby improving the stability of the overall structure of the wall connection.

[0095] S1202, sleeve the pull rod fixing nut 340 onto the through-wall bolt 200 to prevent the through-wall bolt 200 from moving toward the inner wall.

[0096] In this embodiment, the tie rod fixing nut 340 is sleeved on the through-wall bolt 200 and is screwed by a tool to a state where it fits with the outer surface of the outer wall plate 710. Since the tension washer 410 and the tension fixing nut 420 are both sleeved on the through-wall bolt 200 and fit with the surface of the inner wall plate 720, the through-wall bolt 200 can be fixed in the tension screw hole by the tie rod fixing nut 340 and the tension fixing nut 420, and under the interaction of the tie rod fixing nut 340 and the tension fixing nut 420, the through-wall bolt 200 will not move between the inner wall plate 720 or the outer wall plate 710, which is conducive to improving the stability and safety of the wall connection and avoiding unnecessary cost burden caused by repeated rework.

[0097] S1203, the through-wall bolt 200 is fixedly connected to the steel pipe 500 by means of the first fastener 310 and the fastener fixing nut 320, and then the reverse fixing nut is sleeved on the through-wall bolt 200.

[0098] In this embodiment, the steel pipe 500 and the through-wall bolt 200 are respectively matched with the holes on the first fastener 310, wherein the steel pipe 500 is located above and parallel to the through-wall bolt 200. The fastener fixing bolt 330 is vertically inserted from the top of the first fastener 310 into the first fastener to fix the steel pipe 500 and the through-wall bolt 200 on the first fastener 310. The fastener fixing nut 320 is sleeved on the fastener fixing bolt 330 to fix the fastener fixing bolt 330.

[0099] S1204, fixing the steel pipe 500 to the first upright pole and the second upright pole in the scaffolding assembly 600 through the second fastener 350.

[0100] In this embodiment, since the length of the steel pipe 500 is greater than the pitch between the first and second vertical poles, the steel pipe 500 is sufficient to be erected on the first and second vertical poles after being fixedly connected to the wall connecting member through the first fastener 310. Since the second vertical pole is located between the first vertical pole and the exterior wall panel 710, the steel pipe 500 is first fixedly connected to the second vertical pole through the second fastener 350, and then fixedly connected to the first vertical pole through the second fastener 350. The end of the same steel pipe 500 away from the first fastener 310 is fixedly connected to the first and second vertical poles respectively through the second fastener 350, which helps to enhance the stability of the connection between the wall connecting member and the scaffolding and the anti-overturning ability of the scaffolding and the wall connecting member as a whole, so as to improve the safety of construction.

[0101] In one embodiment, if Figure 6 As shown, S130 includes the following steps:

[0102] S1301, removing a plurality of horizontal bars 620, a plurality of diagonal bars 630 and a plurality of vertical bars from top to bottom in sequence;

[0103] S1302, removing the second fastener 350 to separate the steel pipe 500 from the scaffolding assembly 600, and at the same time, removing the reverse tensile fixing nut 430, the fastener fixing nut 320 and the first fastener 310 in sequence to separate the through-wall bolt 200 from the steel pipe 500;

[0104] S1303, remove the tie rod fixing nut 340, the tension fixing nut 420 and the tension gasket 410, and pull out the through-wall bolt 200 from the tension screw hole;

[0105] S1304. Seal the tension screw holes according to the requirements for sealing tension screw holes in passive buildings.

[0106] Specifically, the difference from the prior art is that the embodiment of the present application does not need to open additional holes or pre-embed the full-length tie rods and steel pipes 500, but makes full use of the tie screw holes set during concrete pouring to insert the through-wall bolts 200, which reduces additional construction content, simplifies the construction process of the wall connection parts, and the reinforcement used in the wall connection parts can be reused, saving construction costs. In addition, one end of the steel pipe 500 is fixedly connected to one end of the through-wall bolt 200 through the first fastener 310, and the other end of the steel pipe 500 is connected to the scaffolding assembly 600 through the second fastener 350, which satisfies the rigidity of the wall connection parts while making it both tensile and compressive, solving the problem of horizontal tie-and-fixing of the operating frame of the passive building thermal insulation integrated wall 100.

[0107] After the construction is completed, the scaffolding assembly 600 is dismantled in order, the steel pipe 500 is separated from the scaffolding assembly 600, the connection between the through-wall bolt 200 and the thermal insulation integrated wall 100 is released, and according to the sealing standard of the tension screw holes of passive buildings, appropriate sealing materials and methods are selected to tightly seal each tension screw hole to ensure the integrity and waterproof performance of the wall.

[0108] The embodiment of the present invention provides a passive building exterior wall scaffolding wall connection part and a construction method thereof, including an insulation integrated wall, a through-wall bolt, a connection assembly, a tension assembly, a steel pipe and a scaffolding assembly; the through-wall bolt is inserted through a preset tension screw hole inside the insulation integrated wall, one end of which is connected to the steel pipe through the connection assembly, and the other end is connected to the tension assembly; the steel pipe is connected to the scaffolding assembly through the connection assembly; the end of the steel pipe connected to the through-wall bolt is in contact with the exterior wall panel on the surface of the insulation integrated wall. In the embodiment of the present invention, there is no need to add additional holes and embedded parts on the exterior wall of the passive building, but the tension screw holes inside the wall are fully utilized to install and fix the wall connection parts, which not only meets the rigid connection of the wall connection parts, but also avoids the generation of cold and hot bridges on the exterior wall of the passive building, simplifies the construction process, and saves construction costs.

Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention.
