Description

Technical Field

[0001] The utility model belongs to the field of building prefabricated walls, in particular to a sandwich type prefabricated thermal insulation wall. Background Art

[0002] The sandwich prefabricated insulation wall is formed by pouring concrete on both sides of the insulation board to form a sandwich-type building exterior wall insulation wall. The insulation board and the concrete are connected by connecting parts, and then the processed wall can be assembled.

[0003] The connectors currently used in thermal insulation walls are generally composed of two parts. Due to installation requirements, the connectors are generally longer. During the processing, it was found that the rod body extending from the inner side of the wall near the connector will cause the connector to be subjected to a greater impact force when the concrete is poured due to the protrusion of the rod body located on the inner side of the wall, causing the connector to shake or tilt, thereby causing the insulation layer or wire mesh to shake or move, affecting the use effect of the connector. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a sandwich type prefabricated thermal insulation wall to solve the problem that the use of connecting pieces is affected during the current concrete pouring process.

[0005] In order to solve the above problems, the utility model adopts the following technical solutions:

[0006] A sandwich prefabricated insulation wall comprises an insulation layer and structural layers arranged on both sides of the insulation layer, the insulation layer is provided with connecting pieces connected to the structural layers on both sides, the connecting pieces comprise a first fixed plate and a second fixed plate which are coaxially arranged in sequence, a fixing pipe is coaxially arranged at one end of the first fixed plate close to the second fixed plate, a traction strip is coaxially arranged in the fixing tube, the traction strip is fixedly connected to the first fixed plate, a plug-in tube is coaxially arranged at one end of the second fixed plate close to the first fixed plate, the plug-in tube is sleeved with the fixing tube, fixing columns are provided at opposite ends of the first fixed plate and the second fixed plate, the fixing columns on the second fixed plate are connected to the plug-in tube, and a cross-shaped groove is provided at one end of the fixing column away from the first fixed plate or the second fixed plate.

[0007] Furthermore, a clamping protrusion is provided on the inner wall of the fixed tube, a reverse clamping protrusion matching the clamping protrusion is provided on the outer peripheral surface of the plug-in tube, a deformation groove is provided on the plug-in tube, and the plug-in tube is inserted into the fixed tube.

[0008] Furthermore, the inner wall of the fixed pipe is provided with an internal thread, the outer peripheral surface of the plug-in pipe is provided with an external thread matching the internal thread, and the plug-in pipe is threadedly connected to the fixed pipe.

[0009] Furthermore, the fixing column is rotatably connected to the second fixing disk.

[0010] Furthermore, the traction bar is provided with evenly distributed locking protrusions, and the through hole on the fixing column is provided with a fixed locking position matched with the locking protrusions.

[0011] Furthermore, a fixing ring is threadedly connected to the outer peripheral surface of the fixing column.

[0012] Furthermore, an abutment protrusion is provided at one end of the first fixing plate close to the second fixing plate.

[0013] Furthermore, the first fixing plate and the second fixing plate are both provided with reinforcing ribs connected to the fixing columns.

[0017] 2. During the use of the connector in the present application, only one worker is required to complete the installation of the connector. The worker first inserts the first fixing plate into the pre-opened hole on the insulation layer, and then pulls the traction bar on the other side of the insulation layer to connect the first fixing plate and the second fixing plate. Compared with the current connector, which requires two workers to be located on both sides of the insulation layer to install the connector during the installation process, the present application has the advantages of saving labor and improving installation efficiency.

[0022] 7. The setting of the fixing ring can be used to block the wire mesh after the wire mesh enters the cross-shaped groove to prevent the wire mesh from moving out of the cross-shaped groove.

[0023] 8. The arrangement of the abutment protrusions can prevent the first fixing plate from moving randomly during the connection process between the first fixing plate and the second fixing plate.

[0024] 9. The setting of reinforcing ribs can increase the overall strength. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] Example 1

[0033] like Figure 1-4As shown, a sandwich prefabricated thermal insulation wall comprises a thermal insulation layer 2 and a structural layer 1 cast on both sides of the thermal insulation layer 2, a connecting piece connected to the structural layers 1 on both sides is installed on the thermal insulation layer 2, the number of the connecting pieces is multiple and evenly distributed on the thermal insulation layer 2, the connecting piece comprises a first fixed plate 4 and a second fixed plate 5 which are coaxially arranged in sequence, a fixed pipe 6 is coaxially fixed to one end of the first fixed plate 4 close to the second fixed plate 5, a traction strip 7 connected to the first fixed plate 4 is coaxially arranged in the fixed tube 6, a plug-in tube 8 is coaxially arranged at one end of the second fixed plate 5 close to the first fixed plate 4, the fixed tube 6 and the plug-in tube 8 are sleeved, a coaxial fixing column 9 is fixed to the opposite end of the first fixed plate 4 and the second fixed plate 5, the fixing column 9 on the second fixed plate 5 is connected to the plug-in tube 8, and a cross-shaped groove 10 for accommodating a wire mesh 16 is provided at one end of the fixing column 9 away from the first fixed plate 4 or the second fixed plate 5;

[0034] The structural layers 1 on both sides of the insulation layer 2 are provided with wire meshes 16 for increasing the strength of the structural layer 1, and the intersections of the wire meshes 16 are located in the corresponding cross-shaped grooves 10;

[0035] In this embodiment, a clamping protrusion is provided on the inner wall of the fixing tube 6, and a counter-clamping protrusion matching the clamping protrusion is provided on the outer peripheral surface of the plug-in tube 8. A deformation groove is provided on the plug-in tube 8 to facilitate the insertion of the plug-in tube 8 into the fixing tube 6. The plug-in tube 8 is inserted into the fixing tube 6, so as to relatively fix the first fixing plate 4 and the second fixing plate 5.

[0036] In order to further improve the degree of combination of the first fixed plate 4 and the second fixed plate 5, in this embodiment, the traction bar 7 is evenly provided with locking protrusions 11 along its length direction, and the through hole on the fixing column 9 is provided with a fixed locking position 12 adapted to the locking protrusion 11. After the traction bar 7 passes through the through hole, the fixed locking position 12 is engaged with the locking protrusion 11 to prevent the traction bar 7 from moving back.

[0037] In this embodiment, a fixing ring 13 is threadedly connected to the outer circumference of the fixed shaft, and the wire mesh 16 is located inside the fixing ring 13 after entering the cross-shaped groove 10. The fixing ring 13 is provided to tighten the position of the wire mesh 16 to prevent it from leaving the cross-shaped groove 10 when the structural layer 1 is poured;

[0038] In order to prevent the first fixed disk 4 from rotating or shifting during the connection between the first fixed disk 4 and the second fixed disk 5, an abutting protrusion 14 is provided at one end of the first fixed disk 4 close to the second fixed disk 5, and the first fixed disk 4 abuts against the insulation layer 2 through the abutting protrusion 14 to prevent displacement;

[0039] In order to increase the strength of the first fixing plate 4 and the second fixing plate 5 , reinforcing ribs 15 connected to the fixing columns 9 are provided on the first fixing plate 4 and the second fixing plate 5 .

[0040] The heat-insulating layer 2 is a heat-insulating board.

[0041] Method of use: first, open a through hole on the insulation layer 2 that is compatible with the outer circumference of the fixed tube 6. The staff inserts the first fixed disk 4 into the through hole on the left side of the insulation layer 2. The staff pulls the traction bar 7 on the right side of the insulation layer 2 and passes the traction bar 7 through the plug-in tube 8, the second fixed disk 5 and the fixed column 9 in sequence. Then, pull the traction bar 7 and push the second fixed disk 5 toward the first fixed disk 4 to make the plug-in tube 8 pass through the fixed tube 6 until the second fixed disk 5 can no longer be pushed. The first fixed disk 4 and the second fixed disk 5 are connected. The excess traction bar 7 can be cut off or put into the cross-shaped groove 10. After the excess traction bar 7 is processed, the intersection points on the wire mesh 16 are placed in the cross-shaped groove 10 for embedding. The installation of the connecting parts and the wire mesh is completed, the enclosure template is installed, and then concrete is poured on both sides of the insulation layer 2.

[0042] In summary, the present application fixes the first fixed plate 4 through the traction bar 7 to facilitate the connection between the second fixed plate 5 and the first fixed plate 4 to complete the clamping of the insulation layer 2 and the fixation of the wire mesh 16. Without affecting the use effect of the connecting piece, the length of the connecting piece is shortened, and no long rods are provided on both sides of the connecting piece close to the structural layer 1, thereby solving the problem that the use of the connecting piece is affected during the concrete pouring process.

[0043] At the same time, the structural setting of the first fixed plate 4 and the second fixed plate 5 in the present application can reduce the length of the connecting piece, facilitate transportation, and save production costs; and compared with the current connecting piece that requires two people to install it simultaneously from both sides of the insulation board, the present application can complete the installation of the connecting piece by one person, thereby improving work efficiency.

[0044] Example 2

[0045] like Figure 5 As shown, the structure of this embodiment is roughly the same as that of embodiment 1. The difference between this embodiment and embodiment 1 is that, in this embodiment, an internal thread is provided in the fixing tube 6, and an internal thread matching the internal thread is provided on the outer peripheral surface of the plug-in tube 8. The plug-in tube 8 is threadedly connected with the fixing tube 6. A sharp abutment protrusion 14 is provided at one end of the first fixing disk 4 close to the second fixing disk 5. When the first fixing disk 4 and the second fixing disk 5 are connected, the staff will pull the traction bar 7 passing through the second fixing disk 5, and rotate the second fixing disk 5 to make the plug-in tube 8 threadedly connected with the fixing tube 6 until the first fixing disk 4 and the second fixing disk 5 clamp the thermal insulation layer 2. In the process of connecting the first fixing disk 4 and the second fixing disk 5, the setting of the abutment protrusion 14 can prevent the first fixing disk 4 from rotating with the second fixing disk 5 as much as possible.

[0046] At the same time, since the second fixed plate 5 is connected to the first fixed plate 4 by rotation, the cross-shaped groove 10 on the fixing column 9 will rotate during the rotation of the second fixed plate 5, and it may not be aligned with the intersection of the wire mesh 16 after the connection is installed. Therefore, in the present application, the fixing column 9 is rotatably connected to the second fixed plate 5. After the second fixed plate 5 is fixed, the fixing column 9 is rotated to align the cross-shaped groove 10 on the fixing column 9 with the intersection of the wire mesh 16 to facilitate the wire mesh 16 to be fixed in the cross-shaped groove 10.

[0047] In summary, this embodiment uses another connection method to connect the first fixing plate 4 and the second fixing plate 5, thereby providing customers with a variety of choices.
