[0002] Under the general situation of energy conservation and emission reduction, ultra-low energy consumption buildings are continuously promoted and developed in various places. The external enclosure insulation system of ultra-low energy consumption buildings needs to be designed and constructed under high energy-saving standards, and the insulation system is continuous and tight. At the deformation joints of the exterior walls, the insulation material needs to extend into the joints by 1 meter to ensure reliable insulation at the deformation joints, reduce the effect of thermal bridges, and maintain energy-saving effects. For this design requirement, there is often a lack of reasonable construction methods and auxiliary devices during construction to tightly fill the insulation materials into the deformation joints to a depth of 1 meter, resulting in the filling density and actual filling depth of the insulation materials often failing to meet the requirements.

The first internally threaded sleeve 13 and the threaded rod can be integrally formed. The conical body 131 device can be rotated using a tool such as a wrench, so that the conical body 131 on the threaded rod expands outward along the threaded rod, so that the tip of the conical body 131 clamps the wall 1 on both sides of the deformation joint 2, and fixes one side of the horizontal rod 10 in the middle of the deformation joint 2.
[0032] Specifically, Figure 2As shown, the second expansion member includes a pair of screw-shaped fixing members 142 connected to the second internally threaded sleeve 14 by an L-shaped connecting member 141, the L-shaped connecting member 141 intersects the second internally threaded sleeve 14 vertically, and the end of the L-shaped connecting member 141 away from the second internally threaded sleeve 14 is fixed with the screw-shaped fixing member 142 by the sleeve, and the screw-shaped fixing members 142 are symmetrically arranged on both sides of the head of the conical drill bit 12 and contact it, and the tip of the screw-shaped fixing member 142 faces the wall 1. The rotating head 11 of the horizontal rod 10 is rotated by a tool to rotate the horizontal rod 10, and the horizontal rod 10 is pushed forward in the fixed first internally threaded sleeve 13, so that the conical drill bit 12 pushes the screw-shaped fixing member 142 away, and the screw-shaped fixing member 142 expands to the walls 1 on both sides respectively, and the tip of the screw-shaped fixing member 142 clamps the walls 1 on both sides of the deformation joint 2, and the other side of the horizontal rod 10 is fixed in the middle of the deformation joint 2.
[0033] Furthermore, the first expansion piece and the second expansion piece are both made of engineering plastics to reduce the impact on the main body deformation joint 2.
[0034] Furthermore, the horizontal rods 10, the vertical rods 20 and the diagonal rods 30 are all Φ6 steel bars, and the fixed connections between the horizontal rods 10, the vertical rods 20 and the diagonal rods 30 are all in the form of welding, so the overall device is easy to construct.
[0035] In this embodiment, as shown in the figure, the vertical rod 20 is vertically connected to one end of the horizontal rod 10 with the conical drill bit 12, the bottom end of the vertical rod 20 is fixedly connected to the connecting member by a fork 21, and the connection between the vertical rod 20 and the horizontal rod 10 is set to a triangle, which makes the connection more stable.
[0036] Furthermore, the bifurcated pieces 21 at the bottom end of the vertical rod 20 are respectively fixed to the sleeves at one end of the two L-shaped connecting pieces 141, and the connection can be performed by welding.
[0037] Furthermore, the height of the vertical rod 20 is greater than 1 meter, which satisfies the requirement that the auxiliary device extends into the deformation joint 2 to form an internal space at least 1 meter deep, and satisfies the requirement that the thermal insulation material is delivered into the deformation joint 2 at a depth of one meter.
[0038] Furthermore, the rotating head 11 is a hexagonal rotating head.
[0039] Furthermore, the outer surface of the conical drill bit 12 is provided with threads.

The horizontal rod 10 is fixed in the middle of the deformation joint 2 through the expansion pieces at both ends. The horizontal rod 10, the vertical rod 20 and the oblique rod 30 are connected to form a stable right-angled triangle space, in which the inorganic thermal insulation fiber is sprayed from the inside to the outside, and then constructed step by step upward.
[0041] Furthermore, the auxiliary device extending into the deformation joint 2 is provided with a steel mesh 3 below the horizontal rod 10 and outside the vertical rod 20, and the steel mesh 3 is fixed to the horizontal rod 10 and the vertical rod 20 with fixing bolts. Since the steel mesh 3 is blocked on the inside, the spraying construction can be convenient and fast. After using this device, there is a steel mesh 3 at 1 meter inside to control the spraying depth, and the thermal insulation spraying material will not fall into the deep seam, and the material density is more reliable. This device ensures the quality of the depth and density of the thermal insulation extending into the deformation joint 2, thereby making the peripheral thermal insulation system more reliable.
[0042] Furthermore, the thermal insulation material in the deformation joint 2 is made of inorganic thermal insulation fiber.
[0043] In this embodiment, the construction process of an auxiliary device for thermal insulation filling of deformation joints is as follows: the horizontal circular Φ6 steel bars and the vertical circular Φ6 steel bars are directly connected to a vertical state by electric welding at the construction site, and the oblique circular Φ6 steel bars are connected to the horizontal circular Φ6 steel bars 1 and the vertical circular Φ6 steel bars 2 by electric welding; then the wire mesh 3 is fixed to the lower side of the horizontal circular Φ6 steel bars and the outer side of the vertical circular Φ6 steel bars by fixing bolts; then the entire triangular device is placed in the deformation joint 2, and after determining the depth first, the horizontal circular Φ6 steel bar end is fixed with a hexagonal rotating head 11 by a tool to rotate the horizontal circular Φ6 steel bar. Since the surface of the horizontal circular Φ6 steel bar 1 has threads, the horizontal circular Φ6 steel bar is rotated When rotating, the horizontal circular Φ6 steel bar is rotated and pushed inwardly through the first internal threaded sleeve and the tapered drill bit 12 with an outer thread, and the screw-shaped fixing piece 142 of the inner second expansion piece is squeezed and pushed through the tapered drill bit 12 on the inner side of the horizontal circular steel bar, so that the screw-shaped fixing piece 142 expands toward the main wall 1 on both sides of the deformation joint 2, thereby fixing the auxiliary device on the wall 1. After fixing the inside, use a tool to rotate the tapered engineering plastic device 5 with an outer thread, so that it directly expands toward the main wall 1 on both sides of the deformation joint 2, so that the outside of the device is fixed on the wall 1, so as to fix the entire device; after the device is fixed, the inorganic thermal insulation fiber can be sprayed directly from the deep inside and from the inside to the outside.

After the horizontal rod is fixed, a horizontal rod, a vertical rod and a diagonal rod are welded and connected to form a stable right-angled triangle space as a whole. In this space, inorganic thermal insulation fiber is sprayed from the deep inside, and then the device is installed upward step by step, and the construction is carried out in sequence, which solves the problem of the prior art that there is often a lack of reasonable construction methods and auxiliary devices in the construction to tightly fill the thermal insulation material into the deformation joint to a depth of 1 meter, so that the deformation joint position is reliably insulated, the thermal bridge effect is reduced, and the energy-saving effect is maintained.
