Description

Technical Field

[0001] The present invention relates to the field of construction engineering, and more particularly to a construction method of an assembled wall. Background Art

[0002] Prefabricated buildings, also known as prefabricated buildings, refer to a construction method in which building components or parts are pre-made in a factory and then transported to the construction site for assembly.

[0003] Prefabricated walls are one of the most common prefabricated components in our daily life. After the walls are prefabricated in the factory, people transport the walls to the construction site for assembly. There are several positioning holes on the bottom of the wall. People pre-embed several positioning steel bars on the construction site. After people use a crane to lift the wall, they control the position of the wall above the positioning steel bars and control the wall to slowly fall until the positioning steel bars on the construction site are completely inserted into the positioning holes under the wall. After the wall falls, the crane maintains the state of the wall. At the same time, people install support rods on one side of the wall. The two ends of the support rods are fixedly connected to the wall and the ground respectively. People use The verticality of the wall can be adjusted by adjusting the length of the support rod so that the whole wall can remain vertical. The support of the support rod can ensure the state of the wall. At this time, the crane can be directly separated from the wall. At this time, people can pour sleeve grouting in the wall. The sleeve grouting will locate the gap between the steel bar and the positioning hole. After the sleeve grouting solidifies, the support plate is installed between the two adjacent walls. By pouring concrete between the two support plates, the casting connection between the two adjacent walls is realized, thereby ensuring the connection strength between the two walls. After the wall is cast and connected, the support rods on the wall are removed.

[0004] like Figure 1 As shown, in the above construction process, the problem of corner construction is also involved. People form the corner by pouring between two adjacent and perpendicular walls. Before pouring to form the corner, people need to install two supporting plates between the two perpendicular walls. However, support rods are installed on both walls. The support rods are inclined and occupy a relatively large space. The position of the corner is relatively narrow compared with other positions. The support rods between the perpendicular walls are staggered with each other, which makes the space between the corner and the support rods small, which is not conducive to the installation of the supporting plates, thereby increasing the difficulty of construction.

[0005] Therefore, new solutions need to be proposed to solve this problem. Summary of the invention

After alignment, the corner wall is controlled to fall slowly so that the positioning steel bars are inserted into the corresponding positioning holes; Step S3: Support the corner wall, install four support rods on one side of the corner wall, two of which are close to the left side of the corner wall, and the other two are close to the right side of the corner wall, and adjust the lengths of the four support rods so that the corner wall is perpendicular to the ground, and then separate the crane and the corner wall; Step S4: Prioritize grouting, seal the gap between the bottom edge of the corner wall and the ground with cement mortar, and then pour the sleeve grouting into the corner wall so that the sleeve grouting fills the gap between the positioning steel bar and the inner wall of the positioning hole; Step S5: assembling the common wall. When all corner walls have completed the above step S4, the common wall is assembled. After the common wall is hoisted, the positioning steel bars are aligned with the positioning holes below the common wall, and then the common wall is slowly lowered so that the positioning steel bars are inserted into the corresponding positioning holes. Step S6: supporting and grouting ordinary walls, which is different from the above steps S3 and S4 in that the construction object is changed to ordinary walls; Step S7: Install the support plate, drill holes on the side of the corner wall close to the ordinary wall and on the ordinary wall and install expansion bolts, install the steel support plate between the ordinary wall and the corner wall through the expansion bolts, and install the wooden support plate between the ordinary wall and the ordinary wall; Step S8: remove two support rods on the corner wall, remove two support rods of the corner wall away from the steel support plate, and install the wooden support plate between the two corner walls; Step S9: pouring, pouring concrete between two adjacent walls to complete the connection between the two adjacent walls; Step 10: Remove the support and wait until the concrete solidifies before removing all the support rods on the wall.

[0009] The present invention is further configured as follows: the positioning holes located on the lower side of the corner wall include hole one and hole two, the diameter of hole two is larger than the diameter of hole one, the ordinary steel bars are used to be inserted into hole one and the positioning holes on the lower side of the ordinary wall, the thick steel bars are used to be inserted into hole two, and a support groove is also provided on the lower side of the corner wall, the support groove is connected to all holes two, the support block is used to be inserted into the support groove, the hole one is distributed close to one side of the corner wall, the hole two is distributed close to the other side of the corner wall, and the distribution density of hole two is greater than the distribution density of hole one.

[0013] The present invention is further configured such that the distance between the bottom surface of the weight-reducing chamber and the ground is larger the closer to the opening of the weight-reducing chamber.

[0014] In summary, the present invention has the following beneficial effects: By removing the two support rods later, there will be no more staggered support rods between the two adjacent corner walls, so that there is enough space in the corner for installation, which reduces the difficulty of construction workers to install the support plate. At the same time, when planning the support rod setting in the early stage, there is no need to consider the space reserved in the corner position, which reduces the difficulty of planning; By assembling the corner wall first, the sleeve grouting between the corner wall and the positioning steel bar has more time to solidify and cool during the installation of the ordinary wall, so that the solidification degree of the sleeve grouting in the corner wall is better than that of the ordinary wall. Before removing the two support rods near the corner of the corner wall, the adjacent ordinary wall and the corner wall are connected by a steel support plate. The overall strength of the steel support plate is high, and the ordinary wall and the corner wall are connected together, which further increases the fixing strength of the corner wall, so that even if the support frame is removed, the corner wall has a higher fixing strength; By setting up thick steel bars, the supporting strength of the half of the corner wall close to the corner can be increased. The overall diameter of the thick steel bars is relatively large, and the supporting capacity of the wall is stronger than that of ordinary steel bars. In addition, the setting of the support blocks connects multiple thick steel bars to each other, making each thick steel bar a whole, thereby increasing the difficulty of bending the thick steel bars and further increasing the supporting capacity of the thick steel bars for the corner wall.

[0017] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] A construction method for an assembled wall, such as Figure 2 , Figure 3 and Figure 4As shown, the construction method of the assembled wall is applied to the construction and assembly of the wall, the wall includes a common wall 1 and a corner wall 2, two adjacent corner walls 2 are perpendicular to each other, a wooden support plate 11 for pouring concrete is provided between the two adjacent common walls 1, and a steel support plate 12 for pouring concrete is provided between the common wall 1 and the corner wall 2; The construction method of the assembled wall includes the following steps: Step S1: pre-embed steel bars, pre-embed positioning steel bars at the location where the wall is planned to be assembled on the construction site; Step S2: Prioritize the assembly of the corner wall 2, lift the corner wall 2 by a crane and align it so that the positioning steel bar is aligned with the positioning hole below the corner wall 2. After alignment, control the corner wall 2 to slowly fall so that the positioning steel bar is inserted into the corresponding positioning hole; Step S3: Support the corner wall 2, install four support rods 3 on one side of the corner wall 2, two of which are close to the left side of the corner wall 2, and the other two are close to the right side of the corner wall 2, and adjust the lengths of the four support rods 3 so that the corner wall 2 is perpendicular to the ground, and then separate the crane and the corner wall 2; Step S4: Prioritize grouting, after sealing the gap between the lower edge of the corner wall 2 and the ground with cement mortar, pour the sleeve grouting into the corner wall 2 so that the sleeve grouting fills the gap between the positioning steel bar and the inner wall of the positioning hole; Step S5: assembling the common wall 1. When all corner walls 2 have completed the above step S4, the common wall 1 is assembled. After the common wall 1 is hoisted, the positioning steel bars are aligned with the positioning holes below the common wall 1, and then the common wall 1 is slowly lowered so that the positioning steel bars are inserted into the corresponding positioning holes. Step S6: supporting the common wall 1 and grouting the common wall 1, which is different from the above steps S3 and S4 in that the construction object is changed to the common wall 1; Specifically, four support rods 3 are installed on one side of the ordinary wall 1, two of which are close to the left side of the ordinary wall 1, and the other two are close to the right side of the ordinary wall 1. The lengths of the four support rods 3 are adjusted so that the ordinary wall 1 is perpendicular to the ground, and then the crane and the corner wall 2 are separated. However, the number of support rods 3 on the ordinary wall 1 adjacent to the corner wall 2 is different from that on other ordinary walls 1. The number of support rods 3 on the ordinary wall 1 adjacent to the corner wall 2 is six. By increasing the number of support rods 3, the stability of the corner wall 2 is ensured.

[0019] Step S7: Install the support plate, drill holes on the side of the corner wall 2 close to the ordinary wall 1 and on the ordinary wall 1 and install expansion bolts, install the steel support plate 12 between the ordinary wall 1 and the corner wall 2 through the expansion bolts, and install the wooden support plate 11 between the ordinary wall 1 and the ordinary wall 1; Step S8: remove the two support rods 3 on the corner wall 2, remove the two support rods 3 of the corner wall 2 away from the steel support plate 12, and install the wooden support plate 11 between the two corner walls 2; Step S9: pouring, pouring concrete between two adjacent walls to complete the connection between the two adjacent walls; Step 10: Remove the support. After the concrete solidifies, remove all the support rods 3 on the wall.

[0020] The above-mentioned construction process gives priority to installing the corner wall 2, so that during the installation of the ordinary wall 1, the space between the corner wall 2 and the positioning steel bars has more time to solidify and cool, so that the solidification degree of the sleeve grouting in the corner wall 2 is better than that of the ordinary wall 1. Before removing the two support rods 3 near the corner of the corner wall 2, a steel support plate 12 is used to connect the adjacent ordinary wall 1 and corner wall 2. On the one hand, a pouring space is formed between the ordinary wall 1 and the corner wall 2. On the other hand, the overall strength of the steel support plate 12 is high, connecting the ordinary wall 1 and the corner wall 2 together. The number of support rods 3 on the ordinary wall 1 adjacent to the corner wall 2 is large, and it has a higher supporting strength than other ordinary walls 1, so that the ordinary wall 1 can support the corner wall 2, so that the verticality of the corner wall 2 is guaranteed and it is not easy to topple over. Therefore, in the subsequent step S8, after the two support rods 3 are removed, the verticality of the corner wall 2 is not easy to change. When the construction personnel remove the corner wall 2, the verticality of the corner wall 2 is not easy to change. After the two support rods 3 on the drop wall 2 are removed, the support rods 3 located in the corner will not be staggered, which greatly increases the space at the corner position, so that subsequent construction personnel have enough space to drive expansion bolts on the wall and install wooden support plates 11, which greatly reduces the difficulty of installing support plates at the corner position. The wooden support plates 11 are easy to transport and are lighter and easier to install than the steel support plates 12. Therefore, except for the steel support plates 12 between the corner wall 2 and the ordinary wall 1, wooden support plates 11 are used in other positions. A plurality of support strips 13 are formed on one side of the steel support plate 12. The length direction of the support strips 13 is arranged along the width direction of the steel support plate 12. The arrangement of the support strips 13 can increase the strength of the steel support plate 12 in its width direction, making it difficult for the steel support plate 12 to bend in the width direction, thereby ensuring the connection strength of the steel support plate 12 between the corner wall 2 and the ordinary wall 1.

[0021] like Figure 2 and Figure 5 As shown, step S1 includes, Step S11: pre-embed common steel bars 4, and pre-embed common steel bars 4 at the planned positions of the common walls 1 and at part of the planned corner walls 2 on the construction site; Step S12: pre-embed the thick steel bars 5 at the planned corner wall 2 position on the construction site; Step S13: welding the support block 9 , welding the entire support block 9 to the root of each thick steel bar 5 .

[0022] Because the two support rods 3 near the corner position on the corner wall 2 need to be removed later, during the assembly process, by setting the thick steel bars 5, the support strength of the half of the corner wall 2 near the corner can be increased. The overall diameter of the thick steel bars 5 is relatively large, and the supporting capacity of the wall is stronger than that of the ordinary steel bars 4. In addition, the setting of the support block 9 connects multiple thick steel bars 5 to each other, so that each thick steel bar 5 becomes a whole, thereby increasing the difficulty of bending the thick steel bars 5, and further increasing the supporting capacity of the thick steel bars 5 for the corner wall 2. The overall strength of the support block 9 is high, and the side wall of the support block 9 can contact the corner wall 2 to prevent the corner wall 2 from deflecting under the action of the horizontal thrust.

[0023] like Figure 6 As shown, the positioning holes located at the lower side of the corner wall 2 include hole 1 6 and hole 2 7, the diameter of hole 2 7 is larger than the diameter of hole 1 6, ordinary steel bar 4 is used to insert into hole 1 6 and the positioning holes at the lower side of ordinary wall 1, and thick steel bar 5 is used to insert into hole 2 7. The lower side of the corner wall 2 is also provided with a support groove 8, and the support groove 8 is connected with all holes 2 7. The support block 9 is used to insert into the support groove 8. Hole 1 6 is distributed near one side of the corner wall 2, and hole 2 7 is distributed near the other side of the corner wall 2, and the distribution density of hole 2 7 is greater than the distribution density of hole 1 6. The distribution density of thick steel bar 5 is relatively high, which can further ensure the supporting effect of the corner wall 2. The depth of the support groove 8 is less than the height of the support block 9, so that after the corner wall 2 falls, it is necessary to By setting support washers around the ordinary steel bars 4, there is no need to set support washers around the coarse steel bars 5, which is convenient for construction workers. The support washers are set to allow space for the sleeve grouting to flow between the bottom surface of the wall and the ground, so that the sleeve grouting can flow smoothly into each positioning hole. The diameter difference between hole 1 6 and the ordinary steel bar 4 is smaller than the diameter difference between hole 2 7 and the coarse steel bar 5. This arrangement allows more flow space between hole 2 7 and the coarse steel bar 5 for the sleeve grouting to flow in. A flow groove is provided on the top surface of the support block 9, and all the coarse steel bars 5 are exposed at the bottom surface of the flow groove. The setting of the flow groove allows a gap between the support block 9 and hole 2 7 for the sleeve grouting to flow in, thereby ensuring the connection strength between the coarse steel bar 5 and hole 2 7.

[0024] like Figure 5 As shown, a plurality of weight-reducing cavities 10 are provided in the corner wall 2. The weight-reducing cavities 10 are provided near the upper end of the corner wall 2. All the weight-reducing cavities 10 are connected to the same side of the corner wall 2. The weight-reducing cavities 10 are located above the second hole 7. The arrangement of the weight-reducing cavities 10 makes the center of gravity of the corner wall 2 close to the lower end of the corner wall 2, thereby ensuring the stability of the corner wall 2 after assembly.

[0025] Step S8 comprises the following steps: Step S81: removing the two support rods 3 located above the support block 9; Step S82: driving an expansion bolt on one side of the corner wall 2, wherein the expansion bolt close to the top of the corner wall 2 is driven between two adjacent weight reduction cavities 10; Step S83: fix the two wooden support plates 11 by expansion bolts, and form a casting space connected to the weight reduction cavity 10 between the two wooden support plates 11.

[0026] There are multiple weight-reducing cavities 10, and the position for fixing the expansion bolts is between two adjacent weight-reducing cavities 10. This position is a solid position, so that when the construction workers drive the expansion bolts into the corner wall 2, they will not be affected by the weight-reducing cavity 10, and during the pouring process, the concrete in the pouring space will enter the weight-reducing cavity 10 from the opening of the weight-reducing cavity 10, thereby filling the weight-reducing cavity 10. This arrangement can ensure the overall strength of the subsequent corner wall 2. The closer the distance between the bottom surface of the weight-reducing cavity 10 and the ground is to the opening of the weight-reducing cavity 10, the larger it is. This arrangement makes the weight-reducing cavity 10 tilt toward the middle position of the corner wall 2, so that the concrete can flow in faster under the action of gravity.

[0027] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
