Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated building construction, and more specifically, to a construction method of a prefabricated wall panel. Background Art

[0002] With the rapid development of urban rail transit construction, building partition wall projects are also increasing year by year. In the past, building partition wall projects used traditional masonry blocks, that is, bricks and cement mortar were used to build walls. This method is usually suitable for some construction projects with high requirements for wall strength, such as high-rise buildings or load-bearing walls. However, the use of traditional masonry blocks has the disadvantages of slow construction progress, complex construction procedures, difficult construction quality control, low degree of construction mechanization, poor civilized construction environment, and high labor and material investment.

[0003] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, process and manufacture building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) in factories, transport them to construction sites, and assemble and install them on site through reliable connection methods. Compared with traditional processes, prefabricated buildings can shorten the overall construction period by 70%-80%, greatly reducing costs. Prefabricated wall panels, also known as prefabricated wall panels, are reinforced concrete plate-shaped components processed in prefabrication plants or construction sites for building assembly. Prefabricated wall panels show the characteristics of standardization, industrialization, and industrialization in the production process. They can be sawed, cut, drilled, and other construction processes. Their application in prefabricated buildings can effectively shorten the construction period and ensure that the wall structure has frost resistance and impermeability. As a new type of construction material, prefabricated wall panels are safe and harmless, consume relatively less energy, and are more in line with the goals of green, low-carbon, and sustainable development in construction projects.

[0004] However, when assembling the panels, there are often many construction joints, and shrinkage cracks are prone to occur at the joints. These cracks often affect the subsequent fine decoration work and also affect the promotion and application of prefabricated wall panels. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the present invention provides a construction method for an assembled wall panel to solve the problem that shrinkage cracks are prone to occur at the joints of the wall panel.

[0006] The technical solution of the present invention is as follows: A construction method of an assembled wall panel comprises the following steps:

[0007] S1. Place the wall panel installation positioning line, the horizontal double-sided edge line of the partition wall and the door and window opening line on the cast ground beam and the main structure in contact with the wall panel, pop up the vertical line of the facade and the top surface connection line, and arrange them according to the width of the panel;

[0008] S2. Apply special mortar in advance on the top surface of the wall panel, the side surface of the wall panel and the connection between the wall panel and the main structure, and install pipe clamps on the upper and lower ends of the wall panel;

[0009] S3. Use a vertical panel machine or a grab panel machine to install wall panels. When multiple wall panels are spliced, the embedded block of one wall panel is stuck in the embedded groove of another adjacent wall panel, and there is a plate seam between the embedded block and the embedded groove. The seam width of the plate seam is less than or equal to 5mm, and the seam width of the joint between the wall panel and the main structure is 10mm~20mm. The plate seams and joints are filled with bonding mortar. The bonding mortar filled in the plate seams and joints is attached with alkali-resistant glass fiber mesh, and the alkali-resistant glass fiber mesh extends 100mm on both sides of the interface seam.

[0010] Furthermore, before step S1, the following steps are also included:

[0011] Step 1: Measure and lay out the wall panels and structural columns according to the positioning diagram, and locate and mark the positions of the ground beams and structural columns;

[0012] Step 2: Tie the steel bars according to the positioning lines and the required reinforcement drawings. Before tying, roughen the connection surface between the ground beam and the structural column. The roughening depth should not be less than 15mm.

[0013] Step 3: pour concrete in layers and vibrate in layers. The thickness of each pour should not exceed 500mm. First, insert the vibrating rod into the bottom to make it vibrate. Then pour and vibrate at the same time to cast the ground beam.

[0014] Further, in step S2, specifically: mortar and water are mixed in a ratio of 1:0.22 for 5 minutes to 10 minutes to prepare special mortar, the special mortar is applied in advance on the top surface of the wall panel, the side surface of the wall panel and the connection between the wall panel and the main structure, and pipe clamps are installed at the upper and lower ends of the wall panel at a position 80 mm away from the short side of the wall panel, and the pipe clamps are located in the middle of the thickness of the wall panel.

[0015] Further, in step S3, the wall panels are installed using a panel erector, which specifically includes the following steps:

[0016] S31, moving the plate erector to the plate loading position, so that the pressure push rod of the plate erector is pressed against the floor slab or beam;

[0017] S32. A lifting hole with a diameter of 30 mm is set at 50 cm to 80 cm from the top surface of the wall panel. A steel rope wrapped with a soft casing is passed through the lifting hole. The back of the wall panel is fixedly connected to the lifting belt through a steel plate. A through hole with a diameter of 30 mm is set at the center of the steel plate. The steel rope is fixed with a lock after passing through the lifting hole of the wall panel and the through hole of the steel plate. The front of the wall panel is fixedly connected to the steel rope with a hook;

[0018] S33. Start the panel erector and lift the wall panel to the designated position. The ground construction workers adjust the wall panel and fix it with pipe clamps after it is in place. After the wall panel is fixed in place, release the hook and remove the lifting belt to complete the installation of a single wall panel. After the wall panel between the two structural columns is installed, install angle steel on both sides of the top of the wall panel to reinforce the wall panel, and then backfill the lifting hole with special mortar.

[0019] Further, in step S3, the wall panels are installed using a panel grabber, which specifically includes the following steps:

[0020] S31, transport the wall panels to the installation area using a pallet truck, and the panel grabber grabs the wall panels and moves them to the installation location;

[0021] S32. Drive wooden wedges into the bottom of the wall panel and manually adjust the position of the wall panel so that the verticality deviation of the wall is less than 1 / 100 of the wall panel height and the flatness deviation of the wall is 3mm to 5mm; then fix the wall panel to complete the installation.

[0022] Furthermore, the pipe clamp includes a pipe body and a pipe segment connected to the pipe body, the pipe body is a columnar structure, and at least a portion of the pipe body is inserted into the wall panel.

[0023] Furthermore, the pipe body is a hollow galvanized pipe, and the outer diameter of the pipe body is greater than or equal to 15 mm.

[0024] Furthermore, the pipe segment is a galvanized iron plate, the thickness of the pipe segment is greater than or equal to 3 mm, and the length of the pipe segment is greater than or equal to 160 mm.

[0025] Furthermore, it also includes:

[0026] S4, waterproof treatment:

[0027] The waterproofing process specifically includes the following steps:

[0028] S41. Apply reactive polymer cement waterproof coating in layers on the inner wall of the wallboard with a thickness of 2 mm to form a first layer of waterproof coating;

[0029] S42. After the first layer of waterproof coating is dry, apply 5mm thick polymer cement waterproof mortar in layers; apply it in a cross-cross method, with each layer not less than 1mm thick and the overall thickness being 3mm-5mm.

[0030] Further, in step S41, the reactive polymer cement waterproof coating includes an organic component, an inorganic component and water, and the weight ratio of the organic component, the inorganic component and water is 1:(1-2):(0.6-0.9), wherein the organic component is a terminal NCO-based prepolymer obtained by reacting a polyether polyol with a polyisocyanate after vacuum dehydration, and the inorganic component is cement and an inorganic filler, and the inorganic filler is quartz powder, heavy calcium or a mixture thereof.

[0031] The present invention according to the above scheme has the following beneficial effects:

[0032] (1) The present invention provides a method for constructing assembled wall panels, which includes placing the wall panel installation positioning lines, the horizontal double-sided edge lines of the partition walls, and the door and window opening lines, popping up the facade vertical lines and the top surface connection lines, and arranging them according to the panel width. This step ensures the precise positioning and arrangement of the wall panels before installation, and can reduce the problem of excessive or insufficient gaps between the wall panels caused by inaccurate installation positions.

[0033] (2) The present invention provides a construction method for assembled wall panels, which includes applying special mortar on the top and side surfaces of the wall panels and at the connection between the wall panels and the main structure, and installing pipe clamps at the upper and lower ends of the wall panels. This can effectively enhance the connection strength between the wall panels and the main structure and reduce shrinkage stress caused by material differences or temperature changes.

[0034] (3) The present invention provides a construction method for assembled wall panels, which uses a panel erector or a panel grabber to install the wall panels. When multiple wall panels are spliced, the embedded block of one wall panel is stuck in the embedded groove of another adjacent wall panel, and there is a plate seam between the embedded block and the embedded groove. The seam width of the plate seam is less than or equal to 5 mm. The seam width of the joint between the wall panel and the main structure is 10 mm to 20 mm. The plate seams and joints are filled with bonding mortar. The bonding mortar filled in the plate seams and joints is attached with an alkali-resistant glass fiber mesh, and the alkali-resistant glass fiber mesh extends 100 mm on both sides of the interface seam. This design controls the width of the board seam within a range of less than or equal to 5mm. On the one hand, it ensures that the connection between the wall panels through the embedded blocks and the embedded grooves has sufficient accuracy and tightness, so that the embedded blocks can penetrate into the embedded grooves to reach the predetermined embedding depth, thereby enhancing the mechanical bite force of the connection point and improving the connection strength; on the other hand, it helps to reduce the gaps during mortar filling, allowing the mortar to penetrate and solidify, thereby enhancing the bonding force between the wall panels, limiting the entry of air and moisture into the gaps, and reducing the risk of shrinkage cracks caused by environmental factors. The joint width between the wall panel and the main structure is 10mm to 20mm. This range not only ensures the adequacy of mortar filling, but also avoids the difficulty of filling and inconsistent mortar shrinkage caused by too wide joints. If the joint is too wide, it will increase the amount of mortar and the difficulty of construction. The mortar is prone to cracks due to inconsistent shrinkage during the curing process; in addition, too large joints may also become channels for air and moisture to penetrate, accelerating the aging and damage of the wall; if the joint is too narrow, it is easy to cause insufficient mortar filling, unable to form a stable bonding layer, affecting the strength and stability of the joint.

[0042] The following detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings and examples. The following detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of the present invention, but cannot be used to limit the scope of the present invention, that is, the present invention is not limited to the described embodiments.

[0043] In order to better understand the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0044] See also Figure 1 As shown, Figure 1 The following is a construction process flow chart of the assembled ALC wall panels. In this embodiment, according to different design requirements, the main specifications of the ALC wall panels are shown in Table 1.

[0045] Before construction, layout design is carried out in combination with the design drawings, and layout construction drawings are drawn to ensure the accuracy of the positions and sizes of ground beams, structural columns, ALC walls, door and window holes.

[0046] Table 1 ALC wallboard standard specifications

[0047]

[0048] The layout is as follows:

[0049] 1) ALC wall panels are assembled using vertical panels.

[0050] 2) ALC wall panels without door openings are installed from one end of the main wall or column to the other end.

[0051] 3) For ALC wall panels with door openings, the installation order of ALC wall panels is to assemble them from the door and window openings to both ends in sequence.

[0052] 4) Use whole panels for assembly during installation. If there are special circumstances requiring additional panels, the width of the additional panels shall not be less than 200mm.

[0053] 5) When the wall length exceeds 4.8m (i.e. 8 ALC wall panels), additional structural columns are added and the layout is rearranged.

[0054] 6) Structural columns are set at doorways, corners, T-junctions and other special locations based on actual site conditions.

[0055] 7) A ground beam is set at the bottom of the ALC wall panel. When the clear height of the structure is less than 6m, only the ground beam is set and the height of the ground beam is 300mm (based on the structural board surface); when the clear height of the structure is less than 6.5m, the height of the ground beam can be appropriately increased to meet the requirement that the maximum height of the ALC wall panel is not more than 6 meters; when the clear height of the structure is greater than 6.5m, a separate ring beam needs to be added, and the ALC wall panels are arranged in layers. Among them, the clear height of the structure refers to the vertical distance between the upper surface of the floor or ground structure layer and the lower surface of the upper structure layer.

[0056] 8) The ground beam is disconnected at the door opening of the room and the reserved transportation opening.

[0057] The construction method of the assembled ALC wall panel provided by the embodiment of the present invention comprises the following steps:

[0058] A1. Measure and lay out according to the ALC wall panels and structural column positioning drawings, locate and mark the positions of the ground beams and structural columns, reserve the door opening positions according to the drawings before marking, and conduct acceptance after marking to ensure that the marked positions of the ground beams and structural columns are accurate;

[0059] A2. Tie the steel bars according to the positioning lines and the required reinforcement drawings. The specific operations include:

[0060] a. Before binding, the connection surface between the ground beam and the structural column should be roughened, and the roughening depth should not be less than 15mm.

[0061] b. Drilling: Use an impact drill. The drill bit diameter should be about 4mm larger than the steel bar diameter, and the drilling depth should not be less than 220mm.

[0062] c. Hole cleaning: After drilling is completed, the ash in the hole directly affects the quality of rebar planting, and the hole needs to be cleaned.

[0063] d. Glue injection: Glue injection starts from the bottom of the hole. In order to make the glue liquid in the hole full after the steel bar is implanted, but not to make the glue liquid flow out, the glue injection in the hole reaches 1 / 3 of the hole depth or the glue amount in the hole is calculated, minus the volume of the steel bar. After the glue injection in the hole is completed, the steel bar is planted immediately. It is required that the glue injection anchoring should use Class A glue, and the adhesive performance should comply with the provisions of the current standard "Anchoring Glue for Concrete Structure Engineering" JG / T340, and meet the requirements of this project for planting steel bars.

[0064] e. Planting: Use steel bars to plant steel bars, and make sure that the surface of the steel bars is free of rust and other dirt. Apply structural glue to the anchoring end. When planting steel bars, slowly insert the steel bars into the holes and rotate the steel bars to allow the structural glue to overflow from the holes and exhaust the air in the holes. After planting, the exposed length of the steel bars meets the needs of the project.

[0065] f. Rebar binding: Specific requirements for rebar binding should comply with the requirements of the design documents. The overlap with the embedded rebar should meet the overlap specification requirements and set up an encrypted area.

[0066] A3. Fixing the formwork and pouring concrete. The specific operations include:

[0067] 1) Prepare the template: prepare the template according to the geometric dimensions of the drawing;

[0068] 2) Install the template: Before installation, the template must be positioned, the template position must be determined according to the control line, and the template must be coated with a release agent;

[0069] 3) Correct the template: Use ink lines to pop out the edge lines and outer control lines of the template to facilitate template installation and correction. Level the bottom of the template first to ensure the correct position of the template and prevent leakage from the bottom of the template;

[0070] 4) Fixed formwork: The formwork keel is made of square wood, and fasteners are passed through the vertical mortar joints of the wall as fixed anchors. Double-row steel pipe frames are used to reinforce the ring beam formwork;

[0071] 5) Concrete pouring: concrete is poured in layers and vibrated in layers. The thickness of each pouring is not more than 500mm. First, insert the vibrating rod into the bottom to make the vibrating rod vibrate. Concrete is poured and vibrated at the same time to pour the ground beam.

[0072] 6) Disassemble the template.

[0073] A4. Place the ALC wall panel installation positioning line, the horizontal double-sided edge line of the partition wall and the door and window opening line on the cast ground beam and the main structure in contact with the ALC wall panel, pop up the vertical line of the facade and the top connection line, and arrange them according to the width of the board;

[0074] A5. Apply special mortar in advance on the top surface of the ALC wall panel, the side surface of the ALC wall panel and the connection between the ALC wall panel and the main structure, and install pipe clamps on the upper and lower ends of the ALC wall panel;

[0075] A6. Use a vertical panel machine or a grab panel machine to install ALC wall panels. When multiple ALC wall panels are spliced, the embedded block of an ALC wall panel is stuck in the embedded groove of another adjacent ALC wall panel, and there is a plate seam between the embedded block and the embedded groove. The seam width of the plate seam is less than or equal to 5mm. The seam width of the joint between the ALC wall panel and the main structure is 10mm~20mm. The plate seams and joints are filled with bonding mortar. The bonding mortar filled in the plate seams and joints is attached with alkali-resistant glass fiber mesh, and the alkali-resistant glass fiber mesh extends 100mm on both sides of the interface seam.

[0076] Specifically, controlling the width of the panel seam within a range of less than or equal to 5 mm ensures, on the one hand, that the connection between the ALC wall panels through the embedded blocks and the embedded grooves has sufficient precision and tightness, so that the embedded blocks can penetrate into the embedded grooves to reach a predetermined embedding depth, thereby enhancing the mechanical bite force of the connection points and improving the connection strength; on the other hand, it helps to reduce the gaps during mortar filling, allowing the mortar to penetrate and solidify, thereby enhancing the bonding strength between the ALC wall panels, limiting the entry of air and moisture into the gaps, and reducing the risk of shrinkage cracks caused by environmental factors. The width of the joint between the ALC wall panels and the main structure is 10mm to 20mm. This range not only ensures the adequacy of the mortar filling, but also avoids the filling difficulty and inconsistent mortar shrinkage caused by too wide a joint. If the joint is too wide, it will increase the amount of mortar used and the difficulty of construction. The mortar is prone to cracks due to inconsistent shrinkage during the curing process. In addition, too large a joint may also become a channel for air and moisture infiltration, accelerating the aging and damage of the wall. If the joint is too narrow, it is easy to lead to insufficient mortar filling, and it is impossible to form a stable bonding layer, affecting the strength and stability of the joint.

[0077] Before step A4, the method further includes the following steps:

[0078] Step 1: Measure and lay out the ALC wall panels and structural columns according to the positioning diagram, and locate and mark the positions of the ground beams and structural columns;

[0079] Step 2: Tie the steel bars according to the positioning lines and the required reinforcement drawings. Before tying, roughen the connection surface between the ground beam and the structural column. The roughening depth should not be less than 15mm.

[0080] Step 3: pour concrete in layers and vibrate in layers. The thickness of each pour should not exceed 500mm. First, insert the vibrating rod into the bottom to make it vibrate. Then pour and vibrate at the same time to cast the ground beam.

[0081] In step A5, specifically: mortar and water are mixed in a ratio of 1:0.22 for 5 minutes to 10 minutes to prepare special mortar, the special mortar is applied in advance on the top surface of the ALC wall panel, the side surface of the ALC wall panel and the connection between the ALC wall panel and the main structure, and pipe clamps are installed at the upper and lower ends of the ALC wall panel at a position 80 mm away from the short side of the ALC wall panel, and the pipe clamps are located in the middle of the thickness of the ALC wall panel.

[0082] In step A6, the ALC wall panels are installed using a panel erector, which specifically includes the following steps:

[0083] S31, moving the plate erector to the plate loading position, so that the pressure push rod of the plate erector is pressed against the floor slab or beam;

The steel rope is passed through the hoisting hole of the ALC wall panel and the through hole of the steel plate and then fixed with a lock buckle. The front of the ALC wall panel is fixedly connected to the steel rope with a hook;

[0085] S33. Start the panel erector and lift the ALC wall panel to the designated position. The ground construction workers adjust the ALC wall panel and use pipe clamps to fix the ALC wall panel after it is adjusted into place. After the ALC wall panel is fixed in place, release the hook and remove the lifting belt to complete the installation of a single ALC wall panel. After the installation of the ALC wall panel between the two structural columns is completed, install angle steel on both sides of the top of the ALC wall panel to reinforce the ALC wall panel, and then backfill the lifting hole with special mortar.

[0086] In step A6, the ALC wall panels are installed using a panel grabber, which specifically includes the following steps:

[0087] S31. Use a pallet truck to transport the ALC wall panels to the installation area, and the panel grabber grabs the ALC wall panels and moves them to the installation location;

[0088] S32. Drive wooden wedges into the bottom of the ALC wall panel and manually adjust the position of the ALC wall panel so that the verticality deviation of the wall is less than 1 / 100 of the height of the ALC wall panel and the flatness deviation of the wall is 3mm to 5mm; then fix the ALC wall panel to complete the installation.

[0089] In this embodiment, the pipe clamp includes a pipe body and a pipe segment connected to the pipe body. The pipe body is a columnar structure, and at least a portion of the pipe body is inserted into the ALC wall panel.

[0090] In this embodiment, the tube body is a hollow galvanized tube, and the outer diameter of the tube body is greater than or equal to 15 mm.

[0091] In this embodiment, the pipe segment is a galvanized iron plate, the thickness of the pipe segment is greater than or equal to 3 mm, and the length of the pipe segment is greater than or equal to 160 mm.

[0092] In this embodiment, waterproofing treatment is also included, and the waterproofing treatment specifically includes the following steps:

[0094] S42. After the first layer of waterproof coating is dry, apply 5mm thick polymer cement waterproof mortar in layers; apply it in a cross-cross method, with each layer not less than 1mm thick and the overall thickness being 3mm-5mm.
