The cart in step (4) transports the CL network frame board installed with the positioning adjustment components to the wall construction site as follows: put several CL network frame boards side by side on the base plate, and the last CL network frame board Lean on the vertical frame, lean on the other CL network frame boards in turn on the adjacent CL network frame boards on the rear side, manipulate the operation panel, and push the piston rod of the oil cylinder to extend forward to the front of the frontmost CL network frame board. Stop at the top, the piston rod of the hook cylinder is extended downward, and the positioning pin is fixed to the inside of the end surface of the polystyrene board. The worker holds the handrail and pushes the cart to transport the CL grid board to the wall construction site; the hook of the tower crane connects There are two ring-shaped steel wire ropes. First, the piston rod of the push cylinder is controlled to extend, and the upper part of the frontmost CL net frame plate is moved forward to a vertical state through the hook cylinder and positioning nails, and a ring-shaped steel wire rope is hung on the CL net. Two inner concrete blocks or outer concrete blocks at the same height on the front side of the frame plate, the worker first supports the CL grid plate in a vertical state, and then controls the piston rod of the hook cylinder to retract upwards, the positioning pin is separated from the polystyrene plate, and the control is pushed The piston rod of the oil cylinder moves backward to the top of the next polystyrene board, the piston rod of the hooked oil cylinder extends downwards, and the positioning nails are fixed into this polystyrene board, and then another ring-shaped steel wire rope is hung on the CL network frame board The two outer concrete blocks or inner concrete blocks on the rear side, the outer concrete block and the inner concrete block hung by two circular steel wire ropes correspond to each other, and finally start the tower crane to hoist the CL grid slab to the CL grid slab installation control The specified position of the line; follow the above process to hoist all the CL grid panels on the trolley in turn; during the tower crane operation, another trolley is loaded with CL grid panels and pushed to the construction site, and the two carts are transported alternately For the CL grid plate, the tower crane keeps hoisting and placing the CL grid plate in place; during the hoisting and positioning process of the CL grid plate, the two adjacent polystyrene plates are matched with the sealing positioning groove through the convex rib To achieve the effect of positioning and sealing, the two adjacent and connected inner steel wire meshes and the two adjacent and connected outer steel wire meshes are connected as a whole by using overlapping meshes and iron wires.

In step (5), before installing the wall formwork, paint the release agent on the inner wall of the wall formwork, and rotate the inner limit plate and the outer limit plate in advance according to the thickness of the wall, and the inner adjustment rod rotates in the positioning sleeve while moving inward, the outer adjustment rod moves outward while rotating in the positioning sleeve until the distance between the inner limit plate and the outer limit plate is equal to the thickness of the wall and stops. After the wall formwork is installed, the inner wall The body formwork is in contact with the inner limiting plate, and the outer wall formwork is in contact with the outer limiting plate.

The specific process of pouring self-sealing concrete in step (6) is as follows: when pouring self-sealing concrete with a bucket, the distance between the outlet at the bottom of the bucket and the entrance at the top of the wall formwork should be as small as possible, and a string can be added if necessary Or chute to avoid segregation. During the pouring process, the height difference between the inner and outer sides of the polystyrene board should be observed in time. Within 400㎜;

When the self-tightening concrete is pumped, the self-tightening concrete falls from the conveying nozzle, and then a funnel or a baffle is set at the upper opening of the wall formwork, so that the concrete enters the mold at a slower speed, and any At the cross-section, the height difference h of the self-tightening concrete liquid level h caused by the different resistance and flow velocity of the self-tightening concrete on both sides of the polystyrene board should not be greater than 400mm, that is, the self-tightening concrete slurry surface on the outside is higher than that on the inside. The size of the self-tightening concrete slurry surface is controlled within 400mm; during the self-tightening concrete pouring process, a special person is assigned to observe the concrete liquid level height of each section. During observation, it can be measured by flashlight and inserted rod. When the level difference of the self-sealing concrete at the point is close to 400mm, the self-sealing concrete should be poured immediately at this point.

In order to control the flow rate of the self-tightening concrete on both sides of the inner and outer sides of the CL grid slab, during the pouring process of the self-tightening concrete, a steel pipe is vertically inserted into the thicker side of the scaffold to control the cross section, and a hook is welded on the steel pipe for easy extraction. The limiting plate and the outer limiting plate are used to limit the vertical state of the polystyrene board when it is under the pressure of self-tight concrete; The cross-shaped, T-shaped or L-shaped wall intersects to facilitate the uniform flow of self-tight concrete; at the same pouring point, push-type continuous pouring should be used. When switching between multiple pouring points, the front layer should be self-contained. The next layer of self-tightening concrete is poured before the initial setting of the tight concrete.

In order to achieve the purpose of smooth surface when pouring self-tight concrete in step (6), the auxiliary vibration outside the wall formwork adopts leather hammer, small plate vibrator or vibrator along with the self-tight concrete The pouring is vibrated from bottom to top; when pouring in the middle of a concealed column or a composite shear wall with a complex steel structure, a small vibrating rod is used to insert and tamp in an appropriate amount, and the obliquely inserted steel bars of the CL grid slab must not be touched during the tamping.

In step (5), when the wall formwork is in place, lay mortar on the lower part of the wall formwork or draw a mortar joint after it is in place to prevent the lower part of the wall formwork from returning to grout;

Wood screws are used to fix the wall formwork frame of the door and window openings, and steel plate corner guards are added, and the frame is thickened and diagonal supports are added to ensure the overall rigidity of the door and window frames and prevent corner deformation and grout leakage;

The joints of all wall templates are sealed by pressing sponge sealing strips; if necessary, auxiliary measures such as sticking plastic tape or applying sealant can be used to ensure that cement mortar leakage is avoided.

Ventilation holes should be left in the inner corner of the hole or other dead corners. When the self-sealing concrete is poured, it should be observed in time, and it should be sealed immediately after the self-sealing concrete is filled. To prevent the mortar from losing.

The specific process of curing the wall in step (8) is as follows: Since the concrete section in the CL wall after pouring is relatively thin, usually only 60mm thick on the outdoor side, in order to prevent drying shrinkage cracks, the wall formwork should be removed Immediately afterward, cover with plastic film, apply curing agent or cover and water for curing, and the curing time shall not be less than 14 days;

When the horizontal length of the outdoor concrete layer of the CL wall exceeds 26m in the same plane, a vertical separation joint shall be left to guide shrinkage cracks. The shape of the main section of the joint is a triangle with a wide outside and a narrow inside, with a depth of 10mm to 30mm and a width of 10mm to 30mm; the vertical separation joint is cut with a toothless saw or other tools after the final setting of the concrete pouring, and is covered with polyurethane or other external walls. Sealing with elastic building joint sealant; or directly vertically place a rubber or other flexible and elastic material separating strip on the inner wall of the outer wall formwork before concrete pouring, and the dividing strip may be replaced by a waterstop;

After the wall formwork is removed, the bolt holes must be sealed. The plugged bolt holes should be filled with thermal insulation materials as thick as polystyrene boards, and then both ends of the holes should be filled with dry hard mortar or fine stone concrete, and the outside The surface is painted with water-based silicone waterproof coating, and the diameter of the waterproof coating shall not be less than 3 times the diameter of the hole;

After the construction of the CL wall is completed, the outer wall surface should be treated with waterproof and anti-corrosion treatment. The treatment method is as follows:

(1) Remove dust, oil, and soft debris from the wall, remove flow ash, fill holes and gaps; when the vertical flatness of the wall does not meet the requirements, apply a layer of leveling gray base, and then apply protective paint Floor;

(2) Use TN-922 Taineng glue with a weight ratio of 1:1 and 32.5 cement to mix evenly in a container, let it stand for five minutes, remove air bubbles and stir evenly, and then use a brush to paint on the cleaned surface On the base surface of the structure, brush it once and wait for it to dry before painting the next time, a total of three times; the direction of brushing should be applied up and down in the vertical direction to prevent missing brushes; or spray the glue onto the On the cleaned structure base surface, filter it with a 100-mesh sieve when spraying, and use the prepared glue within 2 hours. If the glue thickens, you can add an appropriate amount of Taineng glue to dilute it; after brushing or spraying, three After one pass, use TN-921 Taineng glue, 32.5 cement, and fine sand to mix evenly according to the weight ratio of 1:1.5:2, and let it stand for 5 minutes to stir into a paste-like sand mortar, and use the brushing method to shake it on the surface. On the surface layer, it will have a certain strength after being air-dried for 4 hours, and it will be plastered or pasted with ceramic tiles within 48 hours; use 0.3kg of Taineng glue 921 glue and 0.5kg of 922 glue per square meter of wall surface.

Adopting the above-mentioned technical scheme, the present invention adopts at least two pushcarts to transport and install the CL grid plate with the positioning adjustment assembly, and the tower crane does not stop the hoisting operation, which not only reduces the labor intensity of workers, but also improves the construction efficiency. Set up a small hydraulic station on the rear side of the top of the stand on the rear side of the cart, and through the coordinated operation of the push cylinder and the hook cylinder, the positioning pin is stuck on the top of the last polystyrene board, so that the position of the polystyrene board can be limited , During the cart transportation, ensure the stability of the CL grid plate and prevent the CL grid plate from falling off the cart. In addition, the coordinated operation of the push cylinder and the hook cylinder can push the CL grid plate forward to the vertical state when the tower crane is hoisting the CL grid plate, which can fully reduce the labor intensity of the workers and facilitate the hooking of the ring wire rope. The limit block plays the role of limiting backward slippage when multiple CL grid panels are placed on the bottom plate. Since the small hydraulic station and the push cylinder are all set on the top of the rear side of the cart, when the CL grid plate is not placed on the bottom plate, in order to maintain the stability of the cart, a counterweight is specially set on the front side of the bottom surface of the bottom plate.

The CL network frame plate in the present invention adds a positioning adjustment component near the construction site, and the positioning adjustment component serves to limit the position of the CL network frame plate between the inner wall formwork and the outer wall formwork, so as to avoid the CL network frame when pouring concrete. The pressure difference generated on both sides of the slab causes the phenomenon of leaking ribs, cracking and bulging of the CL grid slab when it bends. The inner concrete block and the outer concrete block are respectively connected with the polystyrene board through positioning sleeves, part of the inner steel wire mesh is pre-embedded inside the inner concrete block, and part of the outer steel wire mesh is pre-embedded inside the outer concrete block, so that the inner steel wire mesh, The polystyrene board and the outer steel wire mesh are fixed and connected as a whole, which fully enhances the strength of the CL grid board. The inner adjustment rod and the outer adjustment rod are threaded in the positioning sleeve, and the length can be adjusted along the axis direction, so that the CL grid plate can be applied to walls of different thicknesses, and the applicable range of the CL grid plate has been improved.

In the present invention, the two adjacent polystyrene boards are fitted through convex-convex joints between the convex ribs and the sealing positioning grooves, and the two adjacent and connected inner steel wire meshes and the two adjacent and connected inner steel meshes are connected by overlapping meshes and iron wires. The adjacent and connected two pieces of outer steel wire mesh are connected as a whole, which not only improves the connection strength between the CL grid slabs, enhances the stability during pouring, but also fully enhances the thermal insulation effect of the poured wall.

To sum up, the present invention has a scientific principle, low labor intensity, high construction efficiency, good thermal insulation effect, more energy-saving and environmental protection, and is suitable for the construction of CL walls with different thicknesses, improves the construction quality, and avoids external thermal insulation of external walls, external Insufficient durability of internal wall insulation; Realize the modernization of the construction industry and the factoryization of construction products.

When the self-sealing concrete is pumped, a funnel or a baffle is set at the top of the wall formwork 8 after the self-sealing concrete falls from the conveying nozzle, so that the concrete enters the mold at a slower speed, and the concrete is placed in the wall formwork 8 At any cross-section, the height difference h of the self-sealing concrete liquid level h caused by the different resistance and flow velocity of the self-sealing concrete on both sides of the polystyrene board 10 should not be greater than 400 mm, that is, the height of the self-sealing concrete slurry surface on the outside The size of the self-tightening concrete slurry surface on the inner side is controlled within 400 mm; during the pouring process of self-tightening concrete, special personnel are assigned to observe the concrete liquid level height of each section. When the height difference of the self-sealing concrete liquid level at a certain section is close to 400 mm, the self-sealing concrete should be poured immediately at this point.

In order to control the flow rate of the self-tightening concrete on both sides of the CL grid slab 9, during the pouring of the self-tightening concrete, a steel pipe is vertically inserted into the thicker side of the scaffold to control the section, and a hook is welded on the steel pipe to facilitate extraction. The inner limit plate 21 and the outer limit plate 22 are used to limit the vertical state of the polystyrene board 10 when it is under the pressure of the self-sealing concrete; The point should be set at the intersection of cross-shaped, T-shaped or L-shaped walls to facilitate the uniform flow of self-tight concrete; it is advisable to use push-type continuous pouring at the same pouring point, and when switching between multiple pouring points, it should be Pouring the next layer of self-sealing concrete before the initial setting of the previous layer of self-sealing concrete.

In order to achieve the purpose of smooth surface when pouring self-tight concrete in step (6), auxiliary vibration outside the wall formwork 8 is carried out. The pouring is vibrated from bottom to top; when pouring in the middle of a concealed column or a composite shear wall with a complex steel structure, use a small vibrating rod to insert and tamp in an appropriate amount, and do not touch the obliquely inserted steel bars 13 of the CL grid slab 9 when inserting and tamping.

In step (5), when the wall formwork 8 is in place, lay mortar on the lower part of the wall formwork 8 or draw a mortar joint after it is in place to prevent the lower part of the wall formwork 8 from returning to grout;

Wooden screws are used to fix the 8 frames of the wall formwork at the door and window openings, and steel plate corner guards are added, and the frame is thickened and diagonal supports are added to ensure the overall rigidity of the door and window frames and prevent corner deformation and grout leakage;

All the seams of the wall formwork 8 are sealed by pressing sponge sealing strips; if necessary, auxiliary measures such as pasting plastic tape or sealing glue can be used on local parts to ensure that cement mortar leakage is avoided.

Ventilation holes should be left in the inner corner of the hole or other dead corners. When the self-sealing concrete is poured, it should be observed in time, and it should be sealed immediately after the self-sealing concrete is filled. To prevent the mortar from losing.

The specific process of curing the wall in step (8) is as follows: since the concrete section in the poured CL wall is relatively thin, usually only 60mm thick on the outdoor side, in order to prevent drying shrinkage cracks, the wall formwork 8 Immediately after removal, cover with plastic film, apply curing agent or cover and water for maintenance, and the curing time shall not be less than 14 days;

When the horizontal length of the outdoor concrete layer of the CL wall exceeds 26m in the same plane, a vertical separation joint shall be left to guide shrinkage cracks. The shape of the main section of the joint is a triangle with a wide outside and a narrow inside, with a depth of 10mm to 30mm and a width of 10mm to 30mm; the vertical separation joint is cut with a toothless saw or other tools after the final setting of the concrete pouring, and is covered with polyurethane or other external walls. Elastic construction sealant sealing; or before concrete pouring, directly vertically place a separating strip of rubber or other soft elastic materials on the inner wall of the outer wall formwork 8, and the separating strip may be replaced by a waterstop;

After the wall formwork 8 is dismantled, the bolt holes must be sealed. The plugged bolt holes should be filled with thermal insulation material with the same thickness as the polystyrene board 10, and then the two ends of the holes should be filled with dry hard mortar or fine stone concrete. And paint a water-based silicone waterproof coating on the outer surface, and the diameter of the waterproof coating shall not be less than 3 times the diameter of the hole;

After the construction of the CL wall is completed, the outer wall surface should be treated with waterproof and anti-corrosion treatment. The treatment method is as follows:

(1) Remove dust, oil, and soft debris from the wall, remove flow ash, fill holes and gaps; when the vertical flatness of the wall does not meet the requirements, apply a layer of leveling gray base, and then apply protective paint Floor;

(2) Use TN-922 Taineng glue with a weight ratio of 1:1 and 32.5 cement to mix evenly in a container, let it stand for five minutes, remove air bubbles and stir evenly, and then use a brush to paint on the cleaned surface On the base surface of the structure, brush it once and wait for it to dry before painting the next time, a total of three times; the direction of brushing should be applied up and down in the vertical direction to prevent missing brushes; or spray the glue onto the On the cleaned structure base surface, filter it with a 100-mesh sieve when spraying, and use the prepared glue within 2 hours. If the glue thickens, you can add an appropriate amount of Taineng glue to dilute it; after brushing or spraying, three After one pass, use TN-921 Taineng glue, 32.5 cement, and fine sand to mix evenly according to the weight ratio of 1:1.5:2, and let it stand for 5 minutes to stir into a paste-like sand mortar, and use the brushing method to shake it on the surface. On the surface layer, it will have a certain strength after being air-dried for 4 hours, and it will be plastered or pasted with ceramic tiles within 48 hours; use 0.3kg of Taineng glue 921 glue and 0.5kg of 922 glue per square meter of wall surface.
