Description

Technical Field

[0002] Ultra-low energy consumption projects, particularly in the construction sector, aim to significantly reduce a building's energy consumption and achieve efficient energy utilization through a series of highly efficient energy-saving designs and technologies. These projects often utilize advanced thermal insulation materials. Sandwich siding is a new building material that offers numerous advantages, including lightweight, soundproofing, heat insulation, fire resistance, waterproofing, and earthquake resistance. Suitable for a variety of applications, including high-rise buildings, villas, factories, warehouses, and commercial buildings, it not only facilitates and reduces construction costs, but also improves residential comfort and building safety.

[0003] The sandwich exterior wall panel consists of an inner page panel, an outer page panel and an insulation layer in the middle. The inner page panel and the outer page panel of the sandwich exterior wall are fixed to each other through truss connectors, for which a single truss fixing device is required.

[0004] Currently, the inner and outer panels of sandwich exterior wall panels are fixed together by truss connectors. The truss connectors should be arranged perpendicular to the steel bars inside the inner and outer panels. However, in actual use, a single truss is buried in the concrete inside the panel, so that there is only a linear support between the inner and outer panels. Moreover, the truss cannot be fixedly connected to the steel bars inside the panel, resulting in poor connection effect and insufficient fixation. Therefore, a single truss fixing device is proposed to solve the above problems. Utility Model Content

[0033] Reference Figures 2-4 , the top of the connecting bottom plate 6 is fixedly connected with a side plate 7, and the side plate 7 is provided with two groups. The two groups of side plates 7 are symmetrically arranged front and back to form a vertical groove.

A locking hole 8 is opened inside the side plate 7. The locking hole 8 is provided in three groups to form an isosceles triangle. A sliding sleeve 9 is slidably connected inside the locking hole 8. A locking groove 10 is opened on the outer periphery of the sliding sleeve 9. There are four groups of locking grooves 10, which are equidistantly distributed on the outer periphery of the sliding sleeve 9. A connecting plate 11 for fixing the connection is fixedly connected to the outside of the sliding sleeve 9. The connecting plate 11 connects the three groups of sliding sleeves 9. The sliding sleeve 9 is slidably connected to a fixing component inside the sliding sleeve 9. The fixing component is used to be fixed to the sliding sleeve 9. The fixing component includes a connecting sleeve 12. The connecting sleeve 12 is provided with three groups, which are opposite to the position of the sliding sleeve 9, and the connecting plate 11 is provided with two groups. The two groups of connecting plates 11 are symmetrically arranged front and back. The connecting sleeve 12 is fixedly connected to the front face of the rear connecting plate 11, and the outer periphery of the connecting sleeve 12 is slidably connected to the inside of the sliding sleeve 9. The sliding sleeve 9 limits the connecting sleeve 12 to slide only forward and backward along the inner wall of the sliding sleeve 9. A deformation groove 13 is opened inside the connecting sleeve 12, and the deformation groove 13 is provided with four groups, which are equidistantly distributed in an annular manner on the outer periphery of the connecting sleeve 12. The deformation groove 13 disconnects the connecting sleeve 12 so that the outer wall of the connecting sleeve 12 can be deformed. A protrusion 14 is fixedly connected to the outer periphery of the connecting sleeve 12, and the front face of the protrusion 14 is set as an inclined surface. The protrusion 14 is clamped in the inside of the locking groove 10 to connect the connecting sleeve 12 and the sliding sleeve 9.

[0034] ReferenceFigure 2 、 Figure 3 and Figure 5 The limiting assembly includes a threaded column 15, a handle for easy rotation is provided at the top of the threaded column 15, the bottom end of the threaded column 15 is rotatably connected to the top surface of the connecting base plate 6, and a threaded block 16 is connected to the outer periphery of the threaded column 15 by a threaded connection. The rotation of the threaded column 15 can drive the threaded block 16 to slide up and down along the outer wall of the threaded column 15, and the back of the threaded block 16 is fixedly connected to the limiting seat 17, and the front inner wall of the limiting seat 17 is elastically connected to the limiting block 19 through a limiting spring 18. When the limiting block 19 is not under force, the limiting spring 18 will push the limiting block 19 backward. One end of the limiting spring 18 is fixedly connected to the front inner wall of the limiting seat 17, and the other end of the limiting spring 18 is fixedly connected to the limiting block 19 On the front side, the outer periphery of the limit block 19 is slidably connected to the inside of the limit seat 17, and the limit seat 17 limits the limit block 19 to slide back and forth only along the inner wall of the limit seat 17. The top surface of the limit block 19 is set to an inclined surface. When the connecting truss 5 is inserted into the inside of the side panel 7, the connecting truss 5 can squeeze the limit block 19 along the inclined surface to make the limit block 19 move forward. The inner side of the limit seat 17 contacts the outer side of the side panel 7, so that the limit seat 17 cannot rotate and can only slide up and down along the front side of the side panel 7. A sliding groove 20 is provided inside the side panel 7. The outer periphery of the limit block 19 is slidably connected to the inside of the sliding groove 20, and the sliding groove 20 limits the limit block 19 from sliding up and down along the inner wall of the sliding groove 20.

[0035] Working principle: When you want to make the fixation between the inner page plate 1 and the outer page plate 3 more stable, first place the lower steel cage 4 on the mold of the inner page plate 1, then insert the longitudinal reinforcement of the steel cage 4 between the two side plates 7, use the limit assembly to fix the connecting bottom plate 6 and the side plate 7 on the steel cage 4, then add concrete to ensure that the openings between the side plates 7 are facing upwards, and when the concrete solidifies, insert the connecting truss 5 between the two side plates 7, and then insert the sliding sleeve 9 into the lock hole 8, and the lock hole 8 on the other side. The connecting sleeve 12 is inserted into the upper part, and the outer protrusion 14 of the connecting sleeve 12 is squeezed by the sliding sleeve 9, causing the side wall of the connecting sleeve 12 to deform. When the protrusion 14 moves to the locking groove 10, the protrusion 14 is not subjected to force and is stuck in the locking groove 10. At this time, the connecting truss 5 and the steel cage 4 are firmly fixed together. After laying the insulation layer, the upper steel cage 4 and the connecting truss 5 are also connected together, and then the concrete of the outer page plate 3 is laid, so that the inner page plate 1 and the outer page plate 3 are firmly fixed together. When you want to fix the connecting base plate 6 on the steel cage 4, insert the longitudinal reinforcement of the steel cage 4 between a group of two side plates 7 at the top of the connecting base plate 6. At this time, the longitudinal reinforcement of the steel cage 4 moves downward to squeeze the limit block 19, so that the limit block 19 slides toward the inside of the limit seat 17 and squeezes the limit spring 18. When the longitudinal reinforcement of the steel cage 4 slides to the bottom of the side plate 7, the steel cage 4 does not contact the limit block 19. At this time, the limit block 19 pops out of the limit seat 17. At this time, the threaded column 15 is rotated again. The threaded column 15 drives the limit seat 17 to move downward through the threaded block 16, clamping the longitudinal reinforcement of the steel cage 4, thereby connecting the steel cage 4 to the fixing device.
