Description

Technical Field

[0001] The present invention relates to the technical field of building structure construction, and particularly relates to a method for constructing an external wall CL building structure system and an assembled structure. Background Art

[0002] The CL building structure system is also known as a composite thermal insulation steel bar welded space frame concrete shear wall. The material composition of the CL structure system is that the CL space frame board is used as the main load-bearing member's skeleton (placed slightly centered, with concrete poured on both sides), and high-pressure and high-strength gypsum board is used as the permanent formwork for constructing and pouring concrete (replacing steel formwork and plastering); at the same time, the internal partition wall is built with high-pressure and high-strength gypsum hollow blocks. The thermal insulation layer of this structure has good durability and high fire resistance limit; the building thermal insulation has the same service life as the structure, and this structure is a method to solve the problem that the service life of current building thermal insulation materials is much shorter than that of building structures.

[0003] The existing CL thermal insulation wall first produces steel bar space frame thermal insulation boards of different model sizes based on specifications, and then the steel bar space frame thermal insulation boards are sequentially spliced on-site to form the shape of the external wall. During the splicing process, there are gaps between adjacent two steel bar space frame thermal insulation boards. In the prior art, most of the time, after the vertical calibration pieces (similar to scaffolding) are removed, additional thermal insulation materials are filled in the gaps to improve the thermal insulation efficiency. However, after the vertical calibration pieces are removed, there is no additional fixing effect on the overlapping position of the steel bar space frame thermal insulation boards, and after filling the thermal insulation materials, there is mostly an expansion and extrusion effect on the gaps. Therefore, it may cause secondary damage to the shape of the steel bar space frame thermal insulation boards.

[0004] In addition, in the prior art, most of the overlapping positions of adjacent two steel bar space frame thermal insulation boards are fixed by welding. However, some thermal insulation boards of certain materials are combustible materials, such as EPS boards, which are widely used but have poor fire resistance. Therefore, when using the welding method to fix the overlapping positions of adjacent two steel bar space frame thermal insulation boards, it is easy to ignite the thermal insulation boards, causing safety problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a method for constructing an external wall CL building structure system and an assembled structure to solve the technical problems in the prior art that after the vertical calibration pieces are removed and thermal insulation materials are filled, it causes secondary damage to the shape of the steel bar space frame thermal insulation boards, and when using the welding method to fix the overlapping positions of adjacent two steel bar space frame thermal insulation boards, it is easy to ignite the thermal insulation boards.

[0006] To solve the above technical problems, the present invention specifically provides the following technical solutions:

[0007] A method for constructing an external wall CL building structure system includes the following steps:

[0008] Step 100: Construct a pile foundation, build a steel bar grid insulation board on the pile foundation, and set vertical calibration pieces at the overlapping positions and the open positions of the steel bar grid insulation board to keep the steel bar grid insulation board in a vertical state;

[0015] Connecting pieces are arranged at the grid intersections at the overlapping positions of the steel bar grid insulation board. One end of the connecting piece is elastically connected to the grid intersection at the overlapping position of the steel bar grid insulation board, and the other end of the connecting piece is connected to another connecting piece by a hanging buckle method, and the hanging buckle positions of the two connecting pieces connected by the hanging buckle are in the same plane.

[0016] As a preferred solution of the present invention, the head of the connecting piece is installed at the grid intersection at the overlapping position of the steel bar grid insulation board through an elastic structure, and a reinforcing rod is arranged at the grid intersection of the steel bar grid insulation board connected to the head of the connecting piece.

[0017] As a preferred embodiment of the present invention, at the intersection of the grids of the steel bar grid heat preservation board, there are vertical steel bars and horizontal steel bars, and the reinforcing rod passes through the horizontal steel bar and is connected to the vertical steel bar in a bundled manner;

[0018] After the reinforcing rod is untied from the vertical steel bar, by adjusting the position of the reinforcing rod on the horizontal steel bar, the distance between two adjacent connectors is compensated.

[0019] As a preferred embodiment of the present invention, in the step 300, the implementation method for caulking adjacent two lapped steel bar grid heat preservation boards in sequence is as follows:

[0020] After the vertical calibration piece is built, use the caulking component to fill the outside of the gap between two adjacent lapped steel bar grid heat preservation boards, and fill the top of the gap between two adjacent lapped steel bar grid heat preservation boards;

[0021] After the vertical calibration piece is removed, use the caulking component to fill the inside of the gap between two adjacent lapped steel bar grid heat preservation boards.

[0022] As a preferred embodiment of the present invention, the specific implementation method for filling the outside of the gap between two adjacent lapped steel bar grid heat preservation boards and filling the inside of the gap between two adjacent lapped steel bar grid heat preservation boards is as follows:

[0023] Set at least one discharge head, and the diameter of the discharge head is small, so that the discharge head can be horizontally inserted into the gap between two adjacent lapped steel bar grid heat preservation boards;

[0024] Regulate the discharge head to move upward between two adjacent connectors, so that the heat preservation material can be filled from bottom to top in sequence in the gap between the two connectors;

[0025] Regulate the discharge head to move outwards, so that the discharge head can move out of the gap between two adjacent steel bar grid heat preservation boards;

[0026] Move the discharge head upward to the position between the next two adjacent connectors, and perform the filling work in the next area until the gaps between two adjacent lapped steel bar grid heat preservation boards are completely filled in sequence.

[0027] As a preferred embodiment of the present invention, the insertion depth of the discharge head is less than the thickness of the steel bar grid heat preservation board, and the implementation method for filling the top of the gap between two adjacent lapped steel bar grid heat preservation boards is as follows:

[0028] Only open the discharge port of one discharge head and temporarily close the discharge ports of other discharge heads;

[0029] Move the discharge head with the open discharge port to the top of the gap between two adjacent overlapping steel bar grid insulation boards and insert it into the gap between two adjacent overlapping steel bar grid insulation boards;

[0030] Fill the top of the gap between two adjacent overlapping steel bar grid insulation boards in sequence from outside to inside.

[0031] In addition, the present invention also provides an assembly structure of an external wall CL building structure system, including:

[0032] A steel bar welded grid, including two or more layers of steel bar welded meshes that play a stress or structural role, with an integrally formed insulation board provided in the middle;

[0033] A connecting piece, installed at the overlapping position on the steel bar welded grid, for sequentially splicing two adjacent steel bar welded grids into an integral module;

[0034] Wherein, the connecting piece is installed on the steel bar welded grid through a reinforcing component, and the reinforcing component is movably installed at the overlapping position on the steel bar welded grid, and can be tied together with the vertical steel bars of the steel bar welded grid, and can also be untied from the vertical steel bars of the steel bar welded grid and move along the horizontal steel bars of the steel bar welded grid to compensate for the distance between two connecting pieces for hanging;

[0035] The reinforcing component includes a reinforcing rod inserted on the horizontal steel bar, and flexible fasteners are provided at both ends of the reinforcing rod, and the reinforcing rod is fixed at the intersection position of the horizontal steel bar or the horizontal steel bar and the vertical steel bar through the flexible fasteners.

[0036] As a preferred solution of the present invention, the connecting piece includes an elastic member connected to the reinforcing component and a horizontal hook rod connected to the elastic member, and the hanging positions of two horizontal hook rods for hanging connection are in the same plane;

[0037] Wherein, a groove is provided at the tail of one of the two horizontal hook rods for hanging connection, and a hook is provided at the tail of the other horizontal hook rod. When two adjacent steel bar welded grids are connected through the connecting piece, the tails of their horizontal hook rods are in the same plane.

[0038] The present invention has the following beneficial effects compared with the prior art:

[0039] (1) Before removing the vertical calibration piece in the present invention, thermal insulation materials are first filled outside the gap and inside the top of the gap. At this time, combined with the positioning effect of the vertical calibration piece, the shape of the steel bar grid thermal insulation board can be stabilized, and then the gap structure and the shapes of the thermal insulation materials outside the gap and inside the top of the gap can be stabilized. After the thermal insulation materials outside the gap and inside the top of the gap are shaped, they can naturally limit the size of the gap. Therefore, after the vertical calibration piece is removed, the gap between two adjacent steel bar grid thermal insulation boards is relatively fixed at this time. When filling the thermal insulation material inside the gap, it will not affect the shape of the steel bar grid thermal insulation board.

[0050] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0051] As Figure 1 shown, the present invention provides a method for building an exterior wall CL building structure system, including the following steps:

[0052] Step 100: Construct a pile foundation, build a steel mesh heat-insulating board on the pile foundation, and set vertical calibration pieces at the overlapping positions and open positions of the steel mesh heat-insulating board to keep the steel mesh heat-insulating board in a vertical state.

[0053] Step 200: The overlapping positions of two adjacent steel mesh heat-insulating boards are spliced through connectors, and multiple steel mesh heat-insulating boards are spliced in sequence to form an integral module.

[0054] Step 300: Before and after removing the vertical calibration pieces, the gaps between two adjacent overlapping steel mesh heat-insulating boards are filled in the order from outside to inside, so that after the overlapping positions of two adjacent steel mesh heat-insulating boards are filled with heat-insulating materials, they are seamlessly spliced into a vertical support wall panel.

[0055] Step 400: After the filled heat-insulating materials are shaped, concrete is poured on both the inner and outer sides of the steel mesh heat-insulating board to form a steel welded mesh concrete composite wall.

[0056] Among them, the constructed steel mesh heat-insulating board structure system is as Figure 2 shown. In this embodiment, in order to ensure that the steel mesh heat-insulating board can maintain a vertical state, after building the steel mesh heat-insulating board on the pile foundation, vertical calibration pieces are set at the overlapping positions and open positions of the steel mesh heat-insulating board. For example, vertical calibration pieces are set at the overlapping positions of two adjacent steel mesh heat-insulating boards and at the corresponding door and window positions of the steel mesh heat-insulating board, so that the included angle between two adjacent steel mesh heat-insulating boards is stable, and the entire steel mesh heat-insulating board as a whole maintains a vertical state under the calibration of the vertical calibration pieces.

[0057] In addition, most of the steel bar grid insulation boards of different model sizes are now produced based on specifications first, and then the steel bar grid insulation boards are spliced in sequence on site to form the shape of the exterior wall. During the splicing process, there are gaps between two adjacent steel bar grid insulation boards. Therefore, in order to improve the insulation efficiency, secondary filling work needs to be carried out on these gaps. In this embodiment, specifically before and after the vertical calibration piece is removed, the gaps between two adjacent overlapping steel bar grid insulation boards are filled in the order of from outside to inside, which can maintain the stable state of the steel bar grid insulation boards.

[0058] Among them, the purpose of the vertical calibration piece at the overlapping position of two adjacent steel bar grid insulation boards is to ensure the stability of the included angle between two adjacent steel bar grid insulation boards. Therefore, before the vertical calibration piece is removed, thermal insulation materials are first filled outside the gap and inside the top of the gap. At this time, during the stabilization process of the steel bar grid insulation board (i.e., during the curing process of the pile foundation cement), combined with the positioning effect of the vertical calibration piece, the shapes of the thermal insulation materials outside the gap and inside the top of the gap can be fixed. At this time, the vertical calibration piece can prevent the filling of the thermal insulation materials from causing deformation of the shape of the steel bar grid insulation board.

[0059] After the thermal insulation materials outside the gap and inside the top of the gap are shaped, they can naturally limit the size on the other side of the gap. Therefore, after the vertical calibration piece is removed, due to the curing of the pile foundation cement and the shaping of the thermal insulation materials outside the gap and inside the top of the gap, the gap between two adjacent steel bar grid insulation boards is relatively fixed at this time. When filling the thermal insulation materials inside the gap at this time, it will not affect the shape of the steel bar grid insulation board.

[0060] Furthermore, most of the existing methods use welding to fix the overlapping positions of two adjacent steel bar grid insulation boards. However, some insulation boards are made of combustible materials, such as EPS boards, which have moisture-proof, waterproof, and thermal insulation properties and are widely used but have poor fire resistance. Therefore, if welding is used to fix the overlapping positions of two adjacent steel bar grid insulation boards, it is easy to ignite the insulation board and cause safety problems.

[0061] Therefore, in this embodiment, the overlapping positions between two adjacent steel bar grid insulation boards are spliced through connectors, and multiple steel bar grid insulation boards are spliced in sequence to form an overall module. This method is safe and reliable and is more efficient and safe than the welding method.

[0062] In order to adapt to the setting of vertical calibration pieces at the overlapping positions and open positions of the steel bar grid insulation boards, in step 100, the vertical calibration pieces are divided into double-sided synchronous calibration pieces at the open positions of each steel bar grid insulation board and single-sided corner-fixing calibration pieces at the overlapping positions of two adjacent steel bar grid insulation boards.

[0063] After setting up the steel bar grid heat preservation board, since the double-sided synchronous calibration parts are set at the open positions of each steel bar grid heat preservation board, such as door and window positions, the inner and outer sides of the steel bar grid heat preservation board can be fixed synchronously. At this time, the double-sided synchronous calibration parts realize the fixing effect on the steel bar grid heat preservation board through the opposing clamping plates, and the calibration surfaces of the double-sided synchronous calibration parts are simultaneously close to the inner and outer sides of the corresponding steel bar grid heat preservation board.

[0064] The single-sided corner fixing calibration part is set at the overlapping position of two adjacent steel bar grid heat preservation boards. In order to maintain the included angle of two adjacent steel bar grid heat preservation boards, the calibration surface of the single-sided corner fixing calibration part is simultaneously close to the inner side of the corresponding steel bar grid heat preservation board, preventing the steel bar grid heat preservation board from being unable to maintain the vertical state under the action of external force.

[0065] It should be further supplemented and explained that only the single-sided corner fixing calibration part needs to be set at the overlapping position of two adjacent steel bar grid heat preservation boards because there are doors and windows on the exterior wall of the house. After setting the double-sided synchronous calibration parts at the door and window positions and cooperating with the single-sided corner fixing calibration parts, the reinforcement effect on at least two walls can be achieved.

[0066] In step 200, the steel bar grid heat preservation board includes mutually parallel and opposing steel bar grid plates, and heat preservation boards located between the steel bar grid plates.

[0067] Connectors are set at the grid intersections at the overlapping positions of the steel bar grid heat preservation boards. Among them, one end of the connector is elastically connected to the grid intersection at the overlapping position of the steel bar grid heat preservation board, and the other end of the connector is connected to another connector by a hanging buckle method, and the hanging buckle positions of the two connectors connected by the hanging buckle are in the same plane.

[0068] The head of the connector is installed at the grid intersection at the overlapping position of the steel bar grid heat preservation board through an elastic structure, and a reinforcement rod is set at the grid intersection of the steel bar grid heat preservation board connected to the head of the connector.

[0069] The grid intersections of the steel bar grid heat preservation board are divided into vertical steel bars and horizontal steel bars. The reinforcement rod passes through the horizontal steel bar and is connected to the vertical steel bar in a bundled manner. After the reinforcement rod is untied from the vertical steel bar, by adjusting the position of the reinforcement rod in the horizontal steel bar, the distance between two adjacent connectors can be compensated.

[0070] It should be supplemented and explained that the connection method of using connectors in this embodiment is safer and more reliable. Further, in order to reduce the operation difficulty and improve the connection method, the connector includes an elastic part and a hanging part. When using the connector to connect the overlapping positions of two steel bar grid heat preservation boards, the connector is pulled to make the elastic part deform and become longer, and the two corresponding connectors are connected through the hanging part.

[0071] Among them, if the elastic part of the connecting piece undergoes excessive deformation, the connecting piece will generate an inward extrusion force on the steel bar grid heat preservation board, affecting the shape of the steel bar grid heat preservation board during the curing and stabilization process. To avoid excessive deformation of the elastic part of the connecting piece, a reinforcing rod is added in this embodiment. When the reinforcing rod is fixed at the intersection of the outermost grid of the steel bar grid heat preservation board and the elastic part of the connecting piece undergoes deformation within a reasonable range, the position of the reinforcing rod is maintained unchanged to compensate for the distance between the two connecting pieces.

[0072] When the reinforcing rod is fixed at the intersection of the outermost grid of the steel bar grid heat preservation board and the elastic part of the connecting piece undergoes excessive deformation, the position of the reinforcing rod can be adjusted until the deformation of the elastic part of the connecting piece is within a reasonable range, so that the two adjacent steel bar grid heat preservation boards can be overlapped together, and at the same time, the connecting piece is prevented from generating an inward extrusion force on the steel bar grid heat preservation board.

[0073] It should also be noted that if the buckle positions of the two connecting pieces connected by buckles are in the same plane, it means that the buckle positions of the two connecting pieces connected by buckles are not "crossed". In this case, the buckle end of the connecting piece will not damage the steel bar grid heat preservation board at the overlapping position, ensuring the heat preservation performance of the steel bar grid heat preservation board.

[0074] In step 300, the method for filling the seams of two adjacent overlapping steel bar grid heat preservation boards in sequence is as follows:

[0075] After the vertical calibration piece is erected, use the seam filling component to fill the outside of the gap between two adjacent overlapping steel bar grid heat preservation boards and the top of the gap between two adjacent overlapping steel bar grid heat preservation boards.

[0076] After the vertical calibration piece is removed, use the seam filling component to fill the inside of the gap between two adjacent overlapping steel bar grid heat preservation boards.

[0077] It should be particularly noted that the order of filling the heat preservation material in the gap between two adjacent overlapping steel bar grid heat preservation boards in this embodiment is crucial. On the one hand, a single-sided fixed angle calibration piece is arranged inside two adjacent overlapping steel bar grid heat preservation boards, which is not convenient for filling the gap before removal. Therefore, the outside and the top of the gap are filled first. Due to the fixing effect of the single-sided fixed angle calibration piece and the double-sided synchronous calibration piece, when filling the heat preservation material in the gap, it will not affect the shape of the steel bar grid heat preservation board. On the other hand, after the heat preservation material is filled in the outside and the top of the gap, the shaped heat preservation material will fix the shape of the gap. In this way, even if the single-sided fixed angle calibration piece and the double-sided synchronous calibration piece are removed, it will not affect the shape of the steel bar grid heat preservation board.

[0078] The specific implementation methods for filling the outside and inside of the gaps between two adjacent overlapping steel bar grid insulation boards are as follows:

[0079] Set at least one discharge head with a small diameter so that the discharge head can be horizontally inserted into the gap between two adjacent overlapping steel bar grid insulation boards.

[0080] Regulate the discharge head to move upward between two adjacent connecting pieces so that the thermal insulation material can be filled upward in sequence in the gap between the two connecting pieces.

[0081] Regulate the discharge head to move outward so that the discharge head can move out of the gap between two adjacent steel bar grid insulation boards;

[0082] Move the discharge head upward to the position between the next adjacent two connecting pieces to perform the filling work in the next area until the gaps between two adjacent overlapping steel bar grid insulation boards are completely filled in sequence.

[0083] In this embodiment, the gaps between the steel bar grid insulation boards are split into multiple segments by connecting pieces. Among them, the multiple segments and each individual segment are filled from bottom to top, ensuring that the flow direction of the thermal insulation material does not contact the discharge head, facilitating the movement of the discharge head, and preventing the discharge head from being fixed in the gap.

[0084] The insertion depth of the discharge head is less than the thickness of the steel bar grid insulation board. The implementation method for filling the top of the gap between two adjacent overlapping steel bar grid insulation boards is as follows:

[0085] Only open the discharge port of one discharge head and temporarily close the discharge ports of other discharge heads;

[0086] Move the discharge head with the open discharge port to the top of the gap between two adjacent overlapping steel bar grid insulation boards and insert it into the gap between two adjacent overlapping steel bar grid insulation boards;

[0087] Fill the top of the gap between two adjacent overlapping steel bar grid insulation boards in sequence from outside to inside.

[0088] In addition, the present invention also provides an assembled structure of an external wall CL building structure system, as Figure 3 and Figure 4 shown, including: a steel bar welded grid 1, a connecting piece 2, and a reinforcement component 3.

[0089] The steel bar welded grid 1 includes two or more layers of steel bar welded meshes that play a stress or structural role, and an integrally formed insulation board is provided in the middle.

[0090] The connecting member 2 is installed at the overlapping position on the steel bar welded grid 1 for sequentially splicing two adjacent steel bar welded grids 1 into an integral module.

[0091] Among them, the connecting member 2 is installed on the steel bar welded grid 1 through the reinforcement assembly 3. The reinforcement assembly 3 is movably installed at the overlapping position on the steel bar welded grid 1 and can be tied together with the vertical steel bars of the steel bar welded grid 1, and can also be untied from the vertical steel bars of the steel bar welded grid 1 and move along the horizontal steel bars of the steel bar welded grid 1 to compensate for the distance between two connecting members 2 for hanging.

[0092] The reinforcement assembly 3 includes a reinforcement rod 31 inserted on the horizontal steel bar. Flexible fasteners 32 are provided at both ends of the reinforcement rod 31. The reinforcement rod 31 is fixed at the intersection of the horizontal steel bar or the horizontal steel bar and the vertical steel bar through the flexible fasteners 32.

[0093] If the elastic part of the connecting member undergoes excessive deformation, the connecting member will generate an inward squeezing force on the steel bar grid heat preservation board, affecting the shape of the steel bar grid heat preservation board during the curing and stabilization process. To avoid excessive deformation of the elastic part of the connecting member, a reinforcement rod is added in this embodiment. When the reinforcement rod is fixed together with the outermost grid intersection of the steel bar grid heat preservation board and the deformation of the elastic part of the connecting member is within a reasonable range, the position of the reinforcement rod is maintained unchanged to compensate for the distance between the two connecting members.

[0094] When the reinforcement rod is fixed together with the outermost grid intersection of the steel bar grid heat preservation board and the deformation of the elastic part of the connecting member is excessive, the position of the reinforcement rod can be adjusted until the deformation of the elastic part of the connecting member is within a reasonable range, so that two adjacent steel bar grid heat preservation boards can be overlapped together, and at the same time, the connecting member is prevented from generating an inward squeezing force on the steel bar grid heat preservation board.

[0095] The connecting member 2 includes an elastic member 21 connected to the reinforcement assembly and a transverse hook rod 22 connected to the elastic member 21. The hanging positions of the two transverse hook rods 22 for hanging connection are in the same plane.

[0096] Among them, a groove is provided at the tail of one of the two transverse hook rods 22 for hanging connection, and a hook is provided at the tail of the other transverse hook rod 22. When two adjacent steel bar welded grids 1 are connected by the connecting member 2, the tails of the transverse hook rods 22 are in the same plane.

[0097] The hanging positions of the two connecting members connected by hanging are in the same plane, which means that the hanging positions of the two connecting members connected by hanging are not "crossed". In this way, the hanging end of the connecting member will not damage the steel bar grid heat preservation board at the overlapping position, ensuring the heat preservation performance of the steel bar grid heat preservation board.

The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
