Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation engineering fixed structures, in particular to a thermal insulation engineering fixed structure. Background Art

[0002] Insulation board is made of polystyrene resin with other raw materials and polymer inclusions, making it moisture-resistant and waterproof. Generally, the insulation board is in direct contact with the concrete, and then bonded together with an adhesive to ensure a more stable and strong bond. However, if the insulation board is installed on the concrete layer relying solely on adhesive, the adhesion will inevitably decrease over time.

[0003] In the existing insulation project construction process, a fixing bolt with an expandable end is usually used for fixing. When the fixing bolt is used, the end of the fixing bolt is generally passed through the insulation board and inserted into a pre-drilled hole, and then a screw is screwed into the inside of the fixing bolt to expand the end of the fixing bolt, thereby achieving a fixing effect. This method of fixing requires screwing the screw, and the steps are relatively cumbersome. In addition, in the existing insulation project fixing structure, in the insulation board construction process, a single insulation board needs to be fixed with four fixing bolts evenly distributed in a rectangular array. There are usually many insulation boards, and more fixing bolts are often required for connection, resulting in low construction efficiency, waste of materials and high costs. Therefore, there is an urgent need for an insulation project fixing structure to solve the above-mentioned shortcomings. Utility Model Content

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Example 1

[0029] The utility model provides a technical solution: a fixed structure for a thermal insulation project, comprising a mounting plate 1, a fixed cylinder 2 fixedly connected to the rear of the mounting plate 1, an inner wall of the fixed cylinder 2 being rotatably connected to an expansion tooth 3, an outer surface of the expansion tooth 3 being fixedly connected to a barb 4, four expansion teeth 3 being provided and evenly distributed in a circular array, a rectangular rod 5 being plugged into the inner wall of the fixed cylinder 2, an end of the rectangular rod 5 being fixedly connected to an extrusion block 6, an outer surface of the extrusion block 6 being slidably connected to the lower surface of the expansion tooth 3, a bolt 7 being threadedly connected to the inner wall of the rectangular rod 5, and the bolt 7 being screwed to the inner wall of the rectangular rod 5. One end of the bolt 7 is fixedly connected to the push rod 8, the inner side wall of the extrusion block 6 is slidably connected to the slider 9, the upper surface of the slider 9 is fixedly connected to the first spring 10, the initial length of the first spring 10 is shorter than the initial length of the second spring 12, the upper end of the second spring 12 abuts against the inner top wall of the extrusion block 6, the upper end of the first spring 10 is fixedly connected to the limiting block 11, the upper end of the limiting block 11 passes through the outer surface of the extrusion block 6, the lower surface of the expansion tooth 3 is provided with a limiting groove 13 adapted to the limiting block 11, and the upper surface of the slider 9 is fixedly connected to the second spring 12.

[0030] In order to improve the construction efficiency, Figures 1 to 7When the front end of the rectangular rod 5 is hammered, the rear end of the extrusion block 6 is driven to squeeze the inner wall of the expansion tooth 3, so that the four expansion teeth 3 are opened outward, and the front end of the rectangular rod 5 is flush with the front of the mounting plate 1. At this time, the limit block 11 is clamped into the inner part of the limit groove 13 by the elastic force of the first spring 10, thereby preventing the rectangular rod 5 from falling off from the inside of the fixing tube 2. The coordinated arrangement of the bolt 7, push rod 8, slider 9, first spring 10 and second spring 12 makes it easy to install it later when it is used. When the second spring 12 is longer than the first spring 10, the second spring 12 can drive the limit block 11 to retract into the inner part of the extrusion block 6, thereby disengaging from the engagement of the limit groove 13, and the rectangular rod 5 can be taken out, making it convenient to dismantle and replace the device and the insulation board. That is, through the cooperation of the expansion tooth 3, the rectangular rod 5 and the extrusion block 6, in use, it is only necessary to insert the rear end of the fixing cylinder 2 into the hole in the wall, directly insert the rectangular rod 5 into the interior of the fixing cylinder 2 and hammer the end of the rectangular rod 5, so that the device can be quickly fixed in the fixing hole on the wall. Compared with the traditional steps of tightening the bolt 7, the operation time is saved, thereby achieving the purpose of improving construction efficiency.

[0031] Example 2

[0032] The utility model provides a technical solution: a connecting piece 14 is fixedly connected to the outer surface of the mounting plate 1, four connecting pieces 14, connecting plates 15 and pressing plates 16 are provided and are evenly distributed in a rectangular array, the front of the connecting piece 14 is fixedly connected to the connecting plate 15, the outer surface of the connecting plate 15 is fixedly connected to the reinforcing rib 17, the outer surface of the reinforcing rib 17 is fixedly connected to the back of the pressing plate 16, the front of the connecting plate 15 is fixedly connected to the pressing plate 16, a through hole 18 is opened in the front of the pressing plate 16, an anti-loosening pin 19 is inserted into the inner side wall of the through hole 18, and two through holes 18 and two anti-loosening pins 19 are provided and are symmetrically arranged.

By setting the connecting piece 14, the connecting plate 15, the pressing plate 16 and the anti-loosening pin 19, the fixed structure of the insulation project has the effect of further improving the construction efficiency and saving costs. In actual use, after the corresponding positions of the four corners of the insulation board are installed with the device, the pressing plate 16 is pressed against the four corners of the insulation board, and then the anti-loosening pin 19 is penetrated through the through hole 18 with a hammer and then hammered into the interior of the insulation board. The setting of the reinforcing rib 17 strengthens the strength of the connecting plate 15 and the pressing plate 16, and then the device can be used to fix the four corners of the insulation board, and the single device The four corners of the four insulation boards can be fixed at the same time, and the number of fixing points is increased from the original four to eight, which improves the fixing effect. That is, through the coordinated arrangement of the connecting piece 14, the connecting plate 15, the pressing plate 16 and the anti-loosening pin 19, holes can be directly punched on the wall at the positions corresponding to the four corners of the insulation board during use. After fixing the device on the wall, the insulation board is clamped behind the pressing plate 16, and then the rear end of the anti-loosening pin 19 is hammered into the insulation board. This reduces the number of insulation board fixing parts used and saves fixing steps, thereby achieving the purpose of further improving construction efficiency and saving costs.
