[0002] Currently, most of the exterior walls of residential buildings are filled with small concrete blocks or aerated blocks, and the main material is reinforced concrete. Since the linear expansion coefficient and shrinkage rate of masonry materials and concrete walls are inconsistent with reinforced concrete, shrinkage cracks will occur at the junction of the exterior wall masonry and concrete wall under temperature stress after completion of construction, and water seepage in the exterior wall often occurs.

[0003] Although the prior art requires that a steel wire mesh be laid at the junction of the exterior wall and the main structure to reduce cracks, the effect is not good, and cracks still occur at the junction of the exterior wall masonry and the concrete wall. Utility Model Content

[0012] Preferably, a spring is connected to one side of the clamping block, and one end of the spring is fixedly connected to the fixing block.

[0013] Compared with the prior art, the utility model has the following beneficial effects: an extruded board body is installed in a concrete infill wall to reduce the weight of the concrete infill wall; vertical structure seam profiles and horizontal structure seam profiles made of plasticized polyvinyl chloride profiles are used to protect the junction between the exterior wall and the main structure, thereby reducing the risk of cracking at the seams; and the installation of the iron sheet support is completed by docking a protrusion on one side of the iron sheet support with a fixed block on one side of the vertical structure seam profile, and engaging the clamping block with the protrusion through a spring.

[0023] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] See also Figures 1 to 5 The utility model provides a technical solution: a sandwich panel exterior wall construction structure seam pulling device, comprising a structural wall 1 and a template 7, a floor beam 2 is fixed on one side of the structural wall 1, and a concrete filling wall 3 is arranged on one side of the floor beam 2.

[0026] A cast-in-place concrete exterior wall 4 is fixed to the outside of the concrete filling wall 3; an extruded board body 5 is fixed to the inside of the cast-in-place concrete exterior wall 4, a structural shear wall 6 is arranged on one side of the cast-in-place concrete exterior wall 4, and formwork 7 is fixed to the outsides of the structural shear wall 6 and the cast-in-place concrete exterior wall 4; a vertical structural seam profile 8 is fixed between the structural shear wall 6 and the cast-in-place concrete exterior wall 4, iron sheet supports 9 are arranged on both sides of the vertical structural seam profile 8, and reinforcing steel bars 10 are penetrated and connected inside the iron sheet supports 9; extruded board fixing ribs 11 are arranged on both sides of the extruded board body 5, a horizontal structural seam profile 12 is fixed to the inside of the cast-in-place concrete exterior wall 4, and structural steel bars are fixed to the inside of the cast-in-place concrete exterior wall 4.

[0027] After the concrete is poured above the beam surface, the horizontal structural seam profile 12 of the lower end beam surface is pressed into the concrete before the concrete is initially set, and the structural steel bar inserting reinforcement is done at the same time. When the concrete is poured to a height close to the wall top surface elevation, the horizontal structural seam profile 12 of the upper end beam surface is set. The setting method is the same as that of the lower end beam surface. A vertical structural seam profile 8 is set between the structural shear wall 6 and the concrete filling wall 3 on which the extruded board body 5 is installed. The vertical structural seam profile 8 is a plasticized polyvinyl chloride profile. Iron sheet support members 9 are equidistantly arranged along the vertical height to support the fixed profile, and it is noted that the horizontal reinforcement is avoided. At the same time, reinforcing steel bars 10 are set to pass through the circular holes of the reinforcing iron sheets to connect with the wall The vertical reinforcement of the body is tied and fixed to form an overall fixation. The extruded board body 5 has the characteristics of light weight, heat preservation and good compression resistance. As a hollow filling of the concrete filling wall 3, it has a great effect on reducing the overall bulk density and load. The plasticized polyvinyl chloride profile is light in weight, convenient to carry and load, convenient to carry and construct, can save labor, and has excellent chemical resistance, good acid resistance, alkali resistance and corrosion resistance. At the same time, it has high mechanical strength, water pressure resistance, external pressure resistance, impact resistance, etc., which can meet the requirements of the device and reduce the risk of cracking at the seam. In this way, the outer wall of the sandwich panel can be treated with seams through the above operation to reduce the risk of cracking at the seams.

[0028] Embodiment 2

[0029] See also Figure 4 and Figure 6 , both sides of the vertical structure seam profile 8 are fixedly connected with fixed blocks 13, and a slide groove for the sliding of the protrusion 14 is provided inside the fixed block 13, and one side of the protrusion 14 is fixedly connected to the iron sheet support 9; the interior of the fixed block 13 is movably connected with a lever 15 through a rotating shaft, and a clamping block 16 is slidably connected to one side of the lever 15, and a movable groove matching the lever 15 is provided inside the clamping block 16, and a clamping groove for the clamping block 16 to engage is provided inside the protrusion 14; a spring 17 is connected to one side of the clamping block 16, and one end of the spring 17 is fixedly connected to the fixed block 13, and the lever 15 forms a rotating structure with the fixed block 13 through the rotating shaft, and the clamping block 16 and the protrusion 14 form a clamping structure.

[0030] In order to facilitate the connection between the iron sheet support 9 and the vertical structure seam profile 8, the protrusion 14 on one side of the iron sheet support 9 is docked with the fixed block 13 on one side of the vertical structure seam profile 8. When the protrusion 14 contacts the inclined surface of the block 16, the block 16 will move and squeeze the spring 17 on one side to shrink it. When the block 16 contacts the slot inside the protrusion 14, the spring 17 will reset and push the block 16 to move, so that the block 16 is engaged with the protrusion 14 to complete the installation of the iron sheet support 9. When the iron sheet support 9 needs to be removed, by toggling the two sets of levers 15, the levers 15 will rotate and the block 16 will be toggled through the movable groove to move, so that the block 16 moves out of the engagement with the protrusion 14. At this time, the movable iron sheet support 9 is separated from the fixed block 13 to complete the disassembly of the iron sheet support 9. The above operation can facilitate the installation of the iron sheet support 9 on the vertical structure seam profile 8.

[0031] In actual use, the vertical structure seam profile 8 and the horizontal structure seam profile 12 are used to protect the junction between the exterior wall and the main structure, thereby preventing the risk of cracking caused by uneven stress.
