Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a rock wool sandwich panel wall structure and a construction method thereof. Background Art

[0002] In a factory building with rock wool sandwich panels as the wall, the rock wool sandwich panels are installed after the foundation and surface structure are completed. The foundation and surface structure include the completion of foundation beams, concrete columns, foundation walls and water spill slopes, etc. Multiple concrete columns are distributed throughout the land, the foundation beam is built between two adjacent concrete columns, the foundation wall is built on the foundation beam, and the water spill slope is built on the outside of the foundation wall. Steel columns are erected on the concrete columns, and the rock wool sandwich panels are fixed between the outsides of multiple steel columns through welding of support components, and the rock wool sandwich panels are located above the water spill slope.

[0003] The problem with the existing rock wool sandwich panel wall structure is that there is a height difference between the indoor and outdoor of the factory building, and during the installation and construction of the rock wool sandwich panel, the welding position of the supporting assembly is limited. As a result, after the installation of the rock wool sandwich panel is completed, there is a gap between the rock wool sandwich panel and the splash slope to form a blank area, and the foundation wall is exposed, affecting the overall appearance of the building. Summary of the invention

[0004] The first object of the present invention is to provide a rock wool sandwich panel wall structure which solves the blank area between the rock wool sandwich panel and the water spill slope and ensures the overall beauty and waterproof ability of the building.

[0005] The second object of the present invention is to provide a construction method for the above-mentioned rock wool sandwich panel wall structure.

[0006] The rock wool sandwich panel wall structure provided by the first purpose of the present invention includes concrete columns, steel columns, foundation walls, splash slopes, support components and rock wool sandwich panels, wherein the foundation wall is arranged between two adjacent concrete columns along a first horizontal direction, and the steel column is erected on the concrete column; in the second horizontal direction, the rock wool sandwich panel is fixed to the outside of the steel column through the support component, and the splash slope is arranged on the outside of the foundation wall, and the second horizontal direction is perpendicular to the first horizontal direction; the rock wool sandwich panel is located above the splash slope; in the height direction, there is a gap between the bottom of the rock wool sandwich panel and the splash slope to form a blank area; the rock wool sandwich panel wall structure also includes a filling component; the filling component includes a square tube frame, multiple steel bars and a panel member; a part of the steel bar is planted in the foundation wall, and another part of the steel bar extends to the blank area; the square tube frame is placed in the blank area, the inner side of the square tube frame is welded to the steel bar, and the top of the square tube frame is welded to the support component; the panel member is fixed to the outside of the square tube frame; the gap between the square tube frame and the splash slope is filled with sealant.

[0007] As can be seen from the above solution, first, since the square tube framework is welded by multiple square steel tubes, the welding of the square tube framework can be carried out according to the width, height and depth of the blank area, so it has a good matching degree; in addition, there is a certain hollow space inside the square tube framework, and the construction personnel can utilize the hollow space as a construction operation space for welding between the steel bars, support components and the square tube framework; in addition, if further strengthening structure is needed, the square tube framework is also convenient for binding with steel bars, and the hollow space of the square tube framework can also be used as a concrete pouring space. Then, filling the gap between the square tube framework and the apron with sealant can further ensure the waterproof ability of the wall structure. Finally, fixing a panel member aligned with the rock wool sandwich panel and having the same or similar color on the outer side of the square tube framework, so as to keep the appearance of the wall structure integral and consistent. The rock wool sandwich panel wall structure provided by the present invention has a small construction difficulty and effectively solves the problem of the blank area between the rock wool sandwich panel and the apron.

[0008] A further solution is that the square tube framework includes a first upper horizontal steel tube, a first lower horizontal steel tube, a second upper horizontal steel tube, a second lower horizontal steel tube, a first vertical steel tube and a second vertical steel tube; the first upper horizontal steel tube and the first lower horizontal steel tube are both arranged along the first horizontal direction, and the first upper horizontal steel tube is located above the first lower horizontal steel tube; the second upper horizontal steel tube and the second lower horizontal steel tube are both arranged along the second horizontal direction, and the second upper horizontal steel tube is located above the second lower horizontal steel tube; the first vertical steel tube and the second vertical steel tube are both arranged along the height direction, and in the second horizontal direction, the second vertical steel tube is closer to the foundation wall than the first vertical steel tube; the first vertical steel tube is fixed between the first upper horizontal steel tube and the first lower horizontal steel tube, and the first upper horizontal steel tube, the first lower horizontal steel tube and at least two first vertical steel tubes form a framework body; in the second horizontal direction, one end of the second upper horizontal steel tube is fixed on the first upper horizontal steel tube, the other end of the second upper horizontal steel tube is connected to the upper end of the second vertical steel tube, one end of the second lower horizontal steel tube is fixed on the first lower horizontal steel tube, and the other end of the second lower horizontal steel tube is connected to the lower end of the second vertical steel tube; the second vertical steel tube is welded to the steel bars, the first upper horizontal steel tube is welded to the support components, and the panel member is fixed on the framework body.

[0009] As can be seen from the above, the square tube framework is welded by multiple square steel tubes with different lengths and extending directions, and the production is simple; the framework body composed of multiple steel tubes ensures the integrity of the side of the square tube framework that cooperates with the panel member. By forming an extending body with the second upper horizontal steel tube, the second lower horizontal steel tube and the second vertical steel tube, the extending body extends into the inner side of the blank area for welding with the steel bars, and only the extending body needs to be welded at the position where the steel bars are implanted, so the material consumption of the square tube framework can be minimized, the welding workload of the square tube framework can be reduced and the cost can be reduced.

[0010] A further solution is that at least two steel bars are arranged between the foundation wall and the second vertical steel pipe in sequence along the height direction.

[0011] As can be seen from the above, this setting can further ensure the connection stability between the square pipe skeleton and the foundation wall.

[0012] A further solution is that the color of the outer surface of the panel member is the same as the color of the outer surface of the rock wool sandwich panel.

[0013] As can be seen from the above, this setting further realizes the overall sense of the appearance of the wall structure.

[0014] A further solution is that the support assembly includes a plurality of support units arranged in sequence along the height direction; each support unit includes a purlin and at least two brackets; in each support unit, the plurality of brackets are respectively fixed on adjacent steel columns, and the plurality of brackets are at the same horizontal height, and the purlin extends along the first horizontal direction and is fixed on the plurality of brackets; the rock wool sandwich panel is fixedly connected with a plurality of purlins of the plurality of support units.

[0015] As can be seen from the above, this setting forms a steel structure network between the plurality of vertically arranged steel columns and the plurality of horizontally arranged purlins, which not only improves the overall strength of the wall structure, but also can more stably fix the rock wool sandwich panel.

[0016] A further solution is that in the height direction, in the lowermost support unit, the bracket is fixed at the bottom of the steel column, the purlin is fixed on the lower side of the bracket, and in the second horizontal direction, the purlin is between the foundation wall and the rock wool sandwich panel, and the purlin is welded to the square pipe skeleton.

[0017] As can be seen from the above, since the square pipe skeleton is located outside the foundation wall and below the horizontal position where the steel column is located, the horizontally extending bracket cannot reach the position where the square pipe skeleton is located to be welded to the square pipe skeleton; in addition, even if a downwardly bent bracket is provided to reach the square pipe skeleton, only one bracket is provided at the bottom of each steel column, the number of welding points is small and limited, and in addition, the position of the bracket may not correspond to the position of the extending body on the square pipe skeleton, so the welding cannot be completed. And by fixing the purlin reversely on the lower side of the bracket, without changing the bracket structure, the purlin can reach the horizontal position below the bottom of the steel column and cooperate with the square pipe skeleton, and the purlin extends along the first direction, and the purlin can cooperate with each extending body on the square pipe skeleton, thereby increasing the welding points and improving the welding strength.

[0018] The construction method of the rock wool sandwich panel wall structure provided by the second object of the present invention is the above-mentioned construction method of the rock wool sandwich panel wall structure; the construction method includes implanting steel bars into the foundation wall; placing the square pipe skeleton in the blank area, and performing welding between the steel bars and the square pipe skeleton and welding between the support assembly and the square pipe skeleton; filling the gap between the square pipe skeleton and the apron with sealant.

[0019] As can be seen from the above solution, the problem of the blank area is solved through several steps such as making the square tube skeleton, implanting steel bars, placing the square tube skeleton, welding the square tube skeleton, and filling with glue, ensuring the overall appearance and improving the waterproof performance. The construction method of the rock wool sandwich panel wall structure provided by the present invention has a relatively low construction difficulty and effectively solves the problem of the blank area between the rock wool sandwich panel and the apron.

[0020] A further solution is that the step of implanting the steel bars into the foundation wall includes a drilling step of drilling holes in the foundation wall to form implant holes; a hole cleaning step of cleaning the implant holes in sequence with a cleaning tool, a pneumatic tool, and alcohol; a glue injection step of injecting implanting glue into the implant holes; and an implanting step of implanting the steel bars into the implant holes and allowing them to stand for a preset time.

[0021] As can be seen from the above, the implantation quality of the steel bars plays an important role in the installation stability of the square tube skeleton. Therefore, it is necessary to control the process quality from several sub-steps such as drilling, hole cleaning, glue injection, and implanting to improve the implantation quality of the steel bars.

[0022] A further solution is that before the implanting step, it also includes a rust removal treatment of the steel bars, and then cleaning the steel bars with alcohol or acetone; rotating the steel bars unidirectionally into the implant holes until the steel bars reach the bottom of the implant holes.

[0023] As can be seen from the above, cleaning and rust removal of the steel bars before implanting can effectively improve the implantation quality of the steel bars.

[0024] A further solution is that before the step of implanting the steel bars into the foundation wall, it also includes a pull-out test step of implanting another steel bar into a concrete specimen and conducting a pull-out test, where the strength grade of the concrete specimen is the same as that of the foundation wall.

[0025] As can be seen from the above, this setting can ensure that the implanted steel bars have sufficient supporting strength, thereby improving the stability of the wall structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] See Figures 1 to 3In the figure, the x-axis direction is the first horizontal direction of the present invention, the y-axis direction is the second horizontal direction of the present invention, and the z-axis direction is the height direction of the present invention. The rock wool sandwich panel wall structure includes a concrete column 9, a steel column 2, a foundation wall 1, a support component 3, a rock wool sandwich panel 4, a water spillway 5 and a filling component, and the filling component includes a square tube skeleton 6, a plurality of steel bars 7 and a panel member 8.

[0031] A plurality of concrete columns 9 are distributed in various places of the plant land, the foundation beam is constructed between two adjacent concrete columns 9, the foundation wall 1 is constructed on the foundation beam, the foundation wall 1 is arranged between two adjacent concrete columns 9 along the x-axis direction, and the water spill slope 5 is arranged outside the foundation wall 1. The steel column 2 is erected on the concrete column 9, in the y-axis direction, the rock wool sandwich panel 4 is fixed to the outside of the steel column 2 through the support assembly 3, and in the z-axis direction, there is a gap between the bottom of the rock wool sandwich panel 4 and the water spill slope 5 to form a blank area 100. If the blank area 100 is not filled, the foundation wall 1 will be exposed through the blank area 100.

[0032] The filling component is used to fill the blank area 100. The plurality of steel bars 7 are arranged along the x-axis direction ( Figure 3 As shown in FIG. 1 , a part of the plurality of steel bars 7 is planted in the foundation wall 1, and another part of the steel bars 7 extends to the blank area 100. The square tube frame 6 is placed in the blank area 100, and the inner side of the square tube frame 6 is welded to the steel bars 7, and the top of the square tube frame 6 is welded to a support unit 31 at the bottom of the support assembly 3. The panel member 8 is fixed to the outer side of the square tube frame 6, and the gap between the square tube frame 6 and the water slope 5, and the gap between the rock wool sandwich panel 4 and the square tube frame 6 are filled with sealant 9, and the sealant 9 is a polyurethane sealant.

[0033] See also Figure 4 , Figure 4 Shown is a partial structure of a square tube skeleton 6, which includes a first upper horizontal steel tube 61, a first lower horizontal steel tube 62, a second upper horizontal steel tube 63, a second lower horizontal steel tube 64, a first vertical steel tube 65 and a second vertical steel tube 66. The first upper horizontal steel tube 61, the first lower horizontal steel tube 62, the second upper horizontal steel tube 63, the second lower horizontal steel tube 64, the first vertical steel tube 65 and the second vertical steel tube 66 are all 40×40×3 square steel tubes.

[0034] The first upper horizontal steel tube 61 and the first lower horizontal steel tube 62 are both arranged along the x-axis direction, and the first upper horizontal steel tube 61 is located above the first lower horizontal steel tube 62; the second upper horizontal steel tube 63 and the second lower horizontal steel tube 64 are both arranged along the y-axis direction, and the second upper horizontal steel tube 63 is located above the second lower horizontal steel tube 64; the first vertical steel tube 65 and the second vertical steel tube 66 are both arranged along the z-axis direction.

[0035] The first vertical steel pipe 65 is fixed between the first upper horizontal steel pipe 61 and the first lower horizontal steel pipe 62. The first upper horizontal steel pipe 61, the first lower horizontal steel pipe 62 and at least two first vertical steel pipes 65 form a frame body.

[0036] In the y-axis direction, one end of the second upper horizontal steel pipe 63 is fixed on the first upper horizontal steel pipe 61, and the other end of the second upper horizontal steel pipe 63 is connected to the upper end of the second vertical steel pipe 66. One end of the second lower horizontal steel pipe 64 is fixed on the first lower horizontal steel pipe 62, and the other end of the second lower horizontal steel pipe 64 is connected to the lower end of the second vertical steel pipe 66.

[0037] Combined Figure 2 and Figure 4 , in the y-axis direction, the second vertical steel pipe 66 is closer to the foundation wall 1 relative to the first vertical steel pipe 65. The second vertical steel pipe 66 is welded to the steel bar 7, the first upper horizontal steel pipe 61 is welded to the support assembly 3, and the panel member 8 is fixed on the frame body formed by the first upper horizontal steel pipe 61, the first lower horizontal steel pipe 62 and the first vertical steel pipe 65.

[0038] Refer again to Figure 1 and Figure 2 , in this embodiment, the support assembly 3 includes three support units 31 arranged in sequence along the z-axis direction. The support unit 31 includes purlins 312 and two brackets 311 at the same horizontal height. The brackets 311 are triangular support frames. In each support unit 31, the two brackets 311 are respectively fixed on two adjacent steel columns 2, and the purlins 312 extend along the x-axis direction and are fixed on the two brackets 311 at the same horizontal height through bolts and nuts.

[0039] In the height direction, from top to bottom, the brackets 311 on the first support unit 31 and the second support unit 31 are both placed upright, and the purlins 312 are supported above the brackets 311, while the brackets 311 on the bottommost support unit 31 are placed upside down, and the purlins 312 are fixed on the lower side of the brackets 311 ( Figure 2 shown). In the z-axis direction, in the bottommost support unit 31, the brackets 311 are fixed at the bottom of the steel column 2, the purlins 312 are fixed on the lower side of the brackets 311, and in the y-axis direction, the purlins 312 are located between the foundation wall 1 and the rock wool sandwich panel 4, and the purlins 312 are welded to multiple second upper horizontal steel pipes 63 of the square pipe skeleton 6.

[0040] Since the square tube framework 6 is located outside the foundation wall 1 and below the horizontal position where the steel column 2 is located, the horizontally extending bracket 311 cannot reach the position where the square tube framework 6 is located to weld with the square tube framework 6. Even if the downward-bent bracket 311 is set to reach the square tube framework 6, only one bracket 311 is provided at the bottom of each steel column 2, the number of welding points is small and limited. In addition, the position of the bracket 311 may not correspond to the position of the extending body on the square tube framework 6, so the welding cannot be completed. After the bracket 311 is reversed, the purlin 312 is fixed to the lower side of the bracket 311. Without changing the structure of the bracket 311, the purlin 312 can reach the horizontal position below the bottom of the steel column 2 and cooperate with the square tube framework 6, and the purlin 312 extends along the first direction. The purlin 312 can cooperate with each extending body on the square tube framework 6, thereby increasing the welding points and improving the welding strength.

[0041] The rock wool sandwich panel 4 is fixedly connected to the three purlins 312 of the three support units 31. The outer surface of the panel member 8 is in the same plane as the outer surface of the rock wool sandwich panel 4, and the color of the outer surface of the panel member 8 is the same as the color of the outer surface of the rock wool sandwich panel 4. This setting further realizes the overall sense of the appearance of the wall structure.

[0042] As Figure 2 and Figure 3 shown, the construction method of the rock wool sandwich panel wall structure includes implanting the steel bars 7 into the foundation wall 1, placing the square tube framework 6 in the blank area 100, welding between the steel bars 7 and the square tube framework 6, and welding between the support assembly 3 and the square tube framework 6, and finally filling the gap between the square tube framework 6 and the apron 5 with the sealant 9.

[0043] In the x-axis direction, a rebar planting position is set every 3 m. At each rebar planting position, two steel bars 7 arranged in sequence along the z-axis direction are implanted into the foundation wall 1, and the steel bars 7 are all welded to the second vertical steel pipe 66 of the square tube framework 6. The step of implanting the steel bars 7 into the foundation wall 1 includes a drilling step, a hole washing step, a glue injection step, and a rebar planting step. The drilling step includes drilling a hole in the foundation wall 1 with an impact drill to form a planting hole. The diameter of the drill bit should be about 5 mm larger than the diameter of the steel bar 7. The drill bit is a φ20 alloy steel drill bit, and the depth of the planting hole is 15d. When drilling, the drill bit should be kept horizontal. The hole washing step uses a cleaning tool, a pneumatic tool, and alcohol to wash the planting hole in sequence. Because there will be a lot of dust and debris inside the planting hole after the hole is drilled, which will directly affect the quality of rebar planting, so the debris in the hole needs to be cleaned up. First, a brush with an extended rod is inserted to the bottom of the planting hole, and the brush is repeatedly twitched back and forth to bring out the dust and debris; then, the compressed air generated by the hair dryer is used to blow out the floating dust in the planting hole; then, the inner wall of the planting hole is wiped with absorbent cotton dipped in alcohol or acetone, and it should be noted that water cannot be used for wiping, as alcohol and acetone are volatile while water is not. Finally, the glue injection step can be carried out only after passing the inspection.

[0044] The glue injection step includes injecting reinforcing glue into the planted holes. Take a set of high-strength reinforcing glue and put it into the sleeve. Place the sleeve on the special manual syringe, slowly pull the trigger, and discard the thinner glue at the platinum package mouth. Then insert the spiral mixing nozzle of the syringe into the bottom of the planted hole. If the length is not enough, it can be extended with a plastic tube. Then pull the trigger. Each time the trigger is pulled, the syringe will retreat a little. This can discharge the air in the planted hole, ensure that the glue in the hole is full after the steel bar is implanted, and prevent the glue from flowing out. The glue injection in the hole reaches 80% and that's enough.

[0045] Subsequently, the steel bar planting step should be carried out immediately. Before the steel bar planting step, it also includes rust removal treatment of the steel bar 7, and then cleaning the steel bar 7 with alcohol or acetone; screw the steel bar 7 into the planted hole unidirectionally until the steel bar 7 reaches the bottom of the planted hole. After the steel bar 7 is implanted, the steel bar should be kept stationary before the high-strength reinforcing glue is completely cured, and the steel bar cannot be vibrated. The high-strength reinforcing glue can be cured at room temperature, and the next process can be carried out after 50h.

[0046] Before the steel bar planting, a pull-out test step is required to test the strength of the steel bar 7. Another steel bar 7 of the same type is implanted into a concrete specimen with the same strength grade as the foundation wall 1 and a pull-out test is carried out to determine whether the steel bar 7 and the reinforcing glue meet the requirements. The specific method is as follows: First, make a concrete specimen with the same strength grade as the concrete component at the steel bar planting part on the foundation wall 1. According to the multiple sub-steps of the above "step of implanting the steel bar 7 into the foundation wall 1", implant 3 groups of steel bars 7 into the concrete specimen. After the reinforcing glue is completely cured, carry out the pull-out test.

[0047] In the filling component provided by the present invention, since the square tube framework 6 is welded by multiple square steel pipes, the welding of the square tube framework 6 can be carried out according to the width, height and depth of the blank area 100, so it has a good matching degree; in addition, there is a certain hollow space inside the square tube framework 6, and the construction personnel can use the hollow space as a construction operation space for welding between the steel bar 7, the support component 3 and the square tube framework 6; in addition, if further strengthening structure is needed, the square tube framework 6 is also convenient for binding with the steel bar 7, and the hollow space of the square tube framework 6 can also be used as a concrete pouring space. Then, the gap between the square tube framework 6 and the apron 5 is filled with sealant 9, which can further ensure the waterproof ability of the wall structure. Finally, a panel member 8 that is aligned with the rock wool sandwich panel 4 and has the same or similar color is fixed on the outside of the square tube framework 6, so as to keep the appearance of the wall structure integral and consistent. The rock wool sandwich panel wall structure provided by the present invention has a relatively small construction difficulty and effectively solves the problem of the blank area 100 between the rock wool sandwich panel 4 and the apron 5.

[0048] Finally, it should be emphasized that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
