In the present invention, the left board, the right board, the connecting rod and the connecting tightening device are provided, so that after the left board and the right board are assembled into a right-angle board through the right board, they are in a tightly connected state. Installing the two right-angle boards on the inner and outer sides of the corner of the floor wall can eliminate the connection gap, so that the corner of the floor wall is in a state of being surrounded by the two right-angle boards. After the wall is poured, the two right-angle boards can completely eliminate the thermal bridge at the corner of the floor wall.

Then, fasten and connect the two right-angle boards through the connecting reinforcement plate. When the concrete is poured between the two right-angle boards and then cured, the connection strength between the two right-angle boards and the wall can be greatly increased.

Description

Technical Field

[0001] The present invention relates to the technical field of building wall thermal insulation treatment, and particularly to a high-performance autoclaved sand-lime aerated concrete thermal insulation board and its non-thermal-bridge strengthened connection construction process. Background Art

[0002] Thermal bridges in floor walls are common problems in existing concrete buildings, which affect the thermal insulation performance of buildings. To eliminate thermal bridges, thermal insulation boards are usually installed on the inner and outer sides of the wall. The common thermal insulation board uses autoclaved sand-lime aerated concrete thermal insulation board, and this thermal insulation board is used as a mold to pour the wall during installation. After pouring, the thermal insulation boards on the inner and outer sides of the wall can eliminate thermal bridges.

[0003] However, due to the existence of corners in existing floor walls and load-bearing columns at the corners, the existing thermal insulation boards are usually straight plate structures, which leads to poor thermal insulation connection and sealing effects at the corners of floor walls. That is to say, thermal bridges are easily formed at the corners of floor walls, which will further affect the thermal insulation performance of buildings.

[0004] Therefore, there is an urgent need in the market for a thermal insulation board that can be easily installed on the inner and outer sides of floor walls to eliminate thermal bridges, and a construction process that can improve the non-thermal-bridge connection strength of the thermal insulation board.

[0005] Thus, the present invention provides a high-performance autoclaved sand-lime aerated concrete thermal insulation board and its non-thermal-bridge strengthened connection construction process. Summary of the Invention

A connecting rod tightening device is arranged inside the left board, and a channel for guiding the connecting rod is opened at one end of the left board. After the connecting rod is inserted into the connecting rod tightening device through the channel, one end of the left board and one end of the right board are in a tightly abutted state. An arc-shaped concave surface adapted to one end of the right board is opened at one end of the left board.

The outer peripheral wall of the coupling rod is provided with an annular limiting groove close to the free end. When the annular limiting groove enters the fixing ring, under the action of the trigger mechanism, as the guide coupling rod continues to be inserted, the elastic telescopic push rod will first abut against the bottom of the annular limiting groove, and then the elastic telescopic push rod will swing inward to apply an inward pulling force to the coupling rod.

[0011] As a further description of the above technical solution:

[0012] The trigger mechanism includes a trigger arm, a safety shaft and an elastic telescopic strut, one end of the trigger arm is rotatably connected in the fixed ring and meshes with one end of the elastic telescopic push rod, the safety shaft is slidably connected to the inner circumferential wall of the fixed ring opposite to the insertion hole, the safety shaft and the insertion hole are coaxial and an annular yielding groove is provided on the outer circumferential wall, one side of the trigger arm is hingedly connected to a position close to the inner circumferential wall in the fixed ring through the elastic telescopic strut, and under the action of the elastic telescopic strut, the trigger arm swings toward the direction of the safety shaft.

[0022] Step 1: Cast a prefabricated concrete center column of a certain height at the corner of the upper surface of the floor slab, and place the foundation wall on the adjacent side of the concrete center column, with the angle between the two foundation walls being a right angle.

[0023] Step 2: Combine the two groups of left plates and right plates into two right-angle plate structures.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Embodiment 1

[0044] Please refer toFigures 1-6 , a high-performance autoclaved sand aerated concrete insulation board. This insulation board is used for internal and external insulation at the outer corners of floors. The insulation board includes a left board 1 and a right board 2. The left board 1 and the right board 2 are of a split structure and can be manufactured separately during production. One end of the right board 2 internally accommodates a limiting shaft 3, and the limiting shaft 3 can be arranged in a rotatable connection structure with the right board 2. A connecting rod 4 is fixedly connected to the outer peripheral wall of the limiting shaft 3, and the free end of the connecting rod 4 extends outside the right board 2. A connecting and tightening device 5 is arranged inside the left board 1. A channel 6 for guiding the connecting rod 4 is opened at one end of the left board 1. The outer diameter of the connecting rod 4 is approximately equal to the inner diameter of the channel 6. The connecting and tightening device 5 functions to tighten the connecting rod 4. After the left board 1 and the right board 2 are connected through the cooperation of the connecting and tightening device 5 and the connecting rod 4, a corner board is formed, and this corner board can be turned into a right-angle board. In this embodiment, the right-angle board is taken as an example for elaboration. During use, this right-angle board is installed on the inner and outer sides of the outer corners of the floor.

[0045] Furthermore, after the connecting rod 4 is inserted into the connecting and tightening device 5 through the channel 6, one end of the left board 1 and one end of the right board 2 are in a tightly abutted state. That is to say, the connecting and tightening device 5 has a tightening function, which can eliminate the gap between the left board 1 and the right board 2, completely eliminate the thermal bridge, and improve the insulation effect.

[0046] Among them, an arc-shaped concave surface 11 adapted to one end of the right board 2 is opened at one end of the left board 1. That is to say, one end of the right board 2 is an arc-shaped convex surface. After the arc-shaped concave surface 11 and the arc-shaped convex surface are pressed against each other, the sealing contact area can be increased. T-shaped connection grooves 7 are opened at the front and back of the left board 1 and the right board 2, which are the connecting parts of external workpieces of the T-shaped connection grooves 7.

[0047] Specifically, the connecting and tightening device 5 includes a fixing ring 51, a triggering mechanism 52, and an elastic telescopic push rod 53. An insertion hole 511 for cooperating with the connecting rod 4 is opened on the outer peripheral wall of the fixing ring 51. This insertion hole 511 is circular. One end of the connecting rod 4 can enter the fixing ring 51 through the insertion hole 511. One end of the elastic telescopic push rod 53 is hinged to a position inside the fixing ring 51 close to the insertion hole 511. The elastic telescopic push rod 53 is a telescopic rod structure with two sections and an internal support spring. An annular limiting groove 41 is opened on the outer peripheral wall of the connecting rod 4 near the free end. When the annular limiting groove 41 enters the fixing ring 51, under the action of the triggering mechanism 52, as the connecting rod 4 continues to be inserted, the elastic telescopic push rod 53 will first abut against the bottom of the annular limiting groove 41, and then the elastic telescopic push rod 53 will swing inward to apply an inward pulling force to the connecting rod 4. That is to say, the function of the triggering mechanism 52 is that as the connecting rod 4 deepens, the elastic telescopic push rod 53 first extends into the annular limiting groove 41, and then swings inward to pull the connecting rod 4, so that the left board 1 and the right board 2 are in a tightly connected state.

[0048] The preferred structure of the trigger mechanism 52 mentioned above is that it includes a trigger arm 521, a safety shaft 522, and an elastic telescopic strut 523. One end of the trigger arm 521 is rotatably connected within the fixed ring and meshes with one end of the elastic telescopic push rod 53. That is to say, one end of the trigger arm 521 is provided with meshing teeth, and one end of the elastic telescopic push rod 53 also has meshing teeth. When the trigger arm 521 swings, it will drive the elastic telescopic push rod 53 to swing, and the swinging directions of the two are opposite. The safety shaft 522 is slidably connected to the inner peripheral wall of the fixed ring 51 opposite to the insertion hole 511. Specifically, during implementation, a guide sleeve sleeving the outside of the safety shaft 522 can be welded to the inner peripheral wall within the fixed ring 51. The safety shaft 522 is coaxial with the insertion hole 511, and an annular relief groove 5221 is provided on its outer peripheral wall. One side of the trigger arm 521 is hinged to a position near the inner peripheral wall within the fixed ring 51 through the elastic telescopic strut 523. The elastic telescopic strut 523 also adopts a telescopic rod structure with two built-in springs. Under the action of the elastic telescopic strut 523, the trigger arm 521 swings towards the direction of the safety shaft 522. In the triggered state of the trigger mechanism 52, the action end of the elastic telescopic strut 523 presses against one side of the annular relief groove 5221 on the safety shaft 522, and the action end of the elastic telescopic push rod 53 presses against the other side of the annular relief groove 5221 on the safety shaft 522, where the action end of the elastic telescopic push rod 53 is close to the free end of the safety shaft 522. Preferably, the trigger arm 521, the safety shaft 522, the elastic telescopic strut 523, and the elastic telescopic push rod 53 are all in the same plane, and this plane is perpendicular to the axis of the fixed ring 51.

[0049] Furthermore, trigger arms 521, elastic telescopic struts 523, and elastic telescopic push rods 53 are provided on both sides of the safety shaft 522. That is to say, a connecting rod 4 is pulled by two symmetric elastic telescopic struts 523, which improves the tightening force of the connection tightener 5 on the connecting rod 4.

[0050] In this embodiment, a circular placement card slot 12 communicating with the channel 6 is provided on one side of the left plate 1. The circular placement card slot 12 is in snap-fit connection with the positioning ring 51. This kind of setting facilitates the removal of the entire connection tightener 5 from the circular placement card slot 12 and reduces the manufacturing difficulty of the left plate 1.

[0051] In this embodiment, connection slots 8 are respectively provided at the other ends of the left plate 1 and the right plate 2. Insertion plates 9 and slots 101 that are in plug-in fit with the insertion plates 9 are respectively provided at the top and bottom of the left plate 1 and the right plate 2. That is to say, this insulation board is a unit board structure, and the insulation coverage area can be increased by the way of stacking and combining. The role of the connection slot 8 is to facilitate connection with other insulation straight plates, so that the entire floor wall is in a full insulation state.

[0052] Please refer to Figure 7 , a construction technology for thermally bridging-free enhanced connection of insulation boards, including the following steps:

[0053] Step 1: Cast a prefabricated concrete center column of a certain height at the corner of the upper surface of the floor slab, and place the foundation wall on the adjacent side of the concrete center column, wherein a steel cage is embedded in the concrete center column, the height of the foundation wall is controlled at 15-20cm, and the angle between the two foundation walls is a right angle.

[0054] Step 2: Combine two groups of left plates 1 and right plates 2 into two right-angle plate structures, and then place the two right-angle plates on the inner right-angle side and the outer right-angle side of the foundation wall respectively, and keep the two right-angle plates and the foundation wall in a fitted state. The space above the concrete center column and between the two right-angle plates is the concrete pouring space.

[0055] Step three, use the connecting reinforcement plate to connect the T-shaped connecting grooves 7 on the two right-angle plates to ensure that the corresponding left plate 1 and right plate 2 on the two right-angle plates are in a parallel state, so as to ensure that the spacing between the inner and outer right-angle plates is stable. Among them, the connecting steel bars are embedded in the middle of the two adjacent concrete columns, and then the connecting reinforcement plate is connected to the connecting steel bars by iron wire. At this time, the concrete column is in a closed and surrounded state by the two right-angle plates.

[0056] Step 4. Install the concrete insulation straight plates on both sides of the foundation wall between the adjacent concrete middle columns on the floor slab, and plug and connect the two ends of the concrete insulation straight plates to the left plate 1 and the right plate 2 respectively, and then use steel bars to connect and fix the concrete insulation straight plates on both sides of the foundation wall. This concrete insulation straight plate adopts the common insulation plate with connecting grooves on the side walls, so that the concrete insulation straight plates on both sides of the foundation wall are close to the foundation wall.

[0057] Step 5: Pour concrete into the cavity enclosed by the right-angle plate and the concrete insulation straight plate, and vibrate the concrete at the same time. After the concrete solidifies, the thermal bridges around the concrete center column and inside and outside the floor wall are completely eliminated, and the connection strength between the insulation board and the concrete wall is also improved.

[0058] Working principle: when in use, assemble the left plate 1 and the right plate 2, insert one end of the connecting rod 4 into the channel 6 on the left plate 1, one end of the connecting rod 4 enters the fixing ring 51 and contacts one end of the safety shaft 522. After pushing the safety shaft 522, the action end of the elastic telescopic push rod 53 moves to the outer wall of the connecting rod 4. When the action end of the elastic telescopic push rod 53 moves to the annular limit groove 41, its action end will extend out and press against the bottom of the annular limit groove 41. When the connecting rod 4 continues to go deeper, the trigger arm 521 will contact the annular yield groove 5221. At this time, under the push of the elastic telescopic support rod 523, the trigger arm 521 swings into the annular yield groove 5221. At the same time, the elastic telescopic push rod 53 will swing toward the direction of the trigger arm 521 in the meshing transmission, thereby pushing the connecting rod 4 to continue moving into the fixing ring 51. At this time, the left plate 1 and the right plate 2 are in a tightly connected state.

[0059] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
