Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a construction method for passing a row of pipes through a floor slab. Background Art

[0002] The number of pipes in rows in various buildings is increasing. Some of these pipes are vertical pipes passing through the floor, and some are horizontal pipes passing through the wall. Usually, there are two ways to construct pipes in rows. One is to reserve openings for each pipe during the pouring of the structural floor and the wall construction stage, then install the casing and pipes, and finally perform secondary pouring between the casing and the structure and seal the casing. The other is to reserve a post-casting strip at the structural floor that passes through, and after the casing and pipes are installed, cast the post-casting strip for the second time, and finally seal it.

[0003] However, in the first construction method, it is necessary to reserve holes in the floor slabs, in which sleeves are arranged, and each sleeve is suitable for inserting each pipe. When the holes are reserved, deviations are likely to occur between the upper and lower floors, resulting in the pipes and sleeves not being concentric when the pipes are subsequently installed. In the second implementation method, when reserving the post-cast strip, the steel bars are not broken, and because the steel bars are exposed for a long time, they are prone to rust and damage, resulting in quality problems after the secondary pouring of the post-cast strip. Summary of the invention

[0004] In view of this, the present invention provides a construction method for pipes in rows to pass through floor slabs, so as to solve the problems of non-concentricity between pipes and casings and exposed steel bars when pipes pass through floor slabs and walls.

[0005] In a first aspect, the present invention provides a construction method for a row of pipes passing through a floor slab, the construction method comprising:

[0006] Measuring the specification parameters of the row of pipes, and manufacturing an integrated casing based on the specification parameters, suitable for inserting the row of pipes into the integrated casing;

[0007] After the formwork of the structural floor is supported, the site is entered to measure and lay out the lines, and the integrated sleeve is firmly fixed according to the laid-out position;

[0008] The row of pipes is hoisted into the integrated casing, and the row of pipes is fixed and sealed.

[0009] Beneficial effects: The embodiment of the present invention integrates the various sleeves in the prior art into an integrated sleeve, which can be directly inserted into all pipelines, so that the size of the integrated sleeve is larger than the size of the single pipeline, thereby improving the fault tolerance size of the integrated sleeve, and further solving the cumulative error caused by too many sleeves during the installation process, and avoiding the problem of the pipeline and the sleeve being out of center. In addition, compared with the plugging of a single sleeve and a single pipeline, this embodiment reduces the number of pluggings by uniformly plugging the integrated sleeve, plugs in place at one time, and can also unify the plugging standards and plugging quality, thereby realizing standardized construction. The overall size of the integrated sleeve is smaller than the overall size of the sleeves set separately for each pipeline, reducing the space occupied by the row of pipelines. The plugging and decorative cover in the integrated sleeve are also integrated, reducing the number of pluggings, plugging in place at one time, and decorating in place at one time, and the plugging standards and quality are unified, thereby realizing standardization. Compared with the traditional installation method, the installation process is greatly reduced, and the efficiency and quality of pipeline installation are improved.

[0010] In an optional embodiment, a predetermined spacing is provided between the inner wall of the integrated sleeve and the outer wall of the row of pipes along the length direction and the width direction of the integrated sleeve.

For ordinary workers in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0042] The number of pipes in rows in various buildings is increasing. Some of these pipes are vertical pipes passing through the floor, and some are horizontal pipes passing through the wall. Usually, there are two ways to construct pipes in rows. One is to reserve openings for each pipe during the pouring of the structural floor and the wall construction stage, then install the casing and pipes, and finally perform secondary pouring between the casing and the structure and seal the casing. The other is to reserve a post-casting strip at the structural floor that passes through, and after the casing and pipes are installed, cast the post-casting strip for the second time, and finally seal it.

[0043] However, in the first construction method, it is necessary to reserve holes in the floor slabs, in which sleeves are arranged, and each sleeve is suitable for inserting each pipe. When the holes are reserved, deviations are likely to occur between the upper and lower floors, resulting in the pipes and sleeves not being concentric when the pipes are subsequently installed. In the second implementation method, when reserving the post-cast strip, the steel bars are not broken, and because the steel bars are exposed for a long time, they are prone to rust and damage, resulting in quality problems after the secondary pouring of the post-cast strip.

[0044] In view of this, the present invention provides a construction method for pipes in rows to pass through floor slabs, so as to solve the problems of non-concentricity between pipes and casings and exposed steel bars when pipes pass through floor slabs and walls.

[0045] Combine the following Figure 1 to Figure 2 , describing an embodiment of the present invention.

[0046] According to an embodiment of the present invention, on the one hand, a construction method for a row of pipes passing through a floor slab is provided, the construction method comprising:

[0047] S1, measuring the specification parameters of the row of pipes 1, and manufacturing the integrated casing 2 based on the specification parameters, suitable for inserting the row of pipes 1 into the integrated casing 2;

[0048] Specifically, in this embodiment, a single pipeline is selected first, and then the specification parameters of each pipeline are measured. The inner diameter of the integrated casing 2 needs to be one to two sizes larger than the single pipeline, that is, the integrated casing 2 is integrated with circular casings that are one to two sizes larger than the single pipeline.

[0049] Furthermore, the row of pipes 1 is formed by arranging a plurality of single pipes side by side. In order to facilitate the insertion of the row of pipes 1 into the integrated sleeve 2, the internal dimensions of the integrated sleeve 2 may be larger than the external dimensions of the row of pipes 1. For example, along the length direction of the integrated sleeve 2, the integrated sleeve 2 may be larger than the outer skins of both ends of the row of pipes 1 by a certain distance, for example, 30mm, 40mm, 50mm, 60mm, 70mm, etc. Along the width direction of the integrated sleeve 2, the integrated sleeve 2 is larger than the outer wall of the pipe with the largest inner diameter in the row of pipes 1 by a certain distance, for example, 30mm, 40mm, 50mm, 60mm, 70mm, etc. If a single pipe needs to be insulated, the external dimensions after insulation are used.

[0050] Furthermore, after the size of the integrated sleeve 2 and the overall required quantity are determined, they are centrally produced in a factory and transported to the construction site.

[0051] Furthermore, the actual position of a single pipe in the row of pipes 1 and the spacing between adjacent pipes can be adjusted according to actual conditions. Through in-depth design, the row of pipes 1 can be reasonably combined, and the position and spacing of the row of pipes 1 can be reasonably planned to ensure that the row of pipes 1 is unobstructed and straight throughout the entire route.

[0052] Furthermore, the size and quantity of the integrated sleeve 2 are determined, including the length, width and height. Since the size of the integrated sleeve 2 is relatively large, in order to ensure the structural bearing capacity, it is necessary to verify whether the steel bars at the openings around the integrated sleeve 2 meet the bearing requirements. If not, the steel bars at the openings need to be reinforced and deepened.

[0053] S2. After the formwork of the structural floor 3 is supported, the integrated sleeve 2 is fixed firmly according to the position of the layout.

[0054] After completing the three formworks of the structural floor slab at the construction site, it means that the construction workers have completed the installation of the formwork of the floor slab, forming a temporary mold of the floor slab structure, and can proceed with the subsequent pouring of concrete.

[0055] Then, the mechanical and electrical installation workers will enter the site to measure and lay out the lines. After entering the site, the workers responsible for mechanical and electrical installation will accurately measure and mark the mechanical and electrical equipment to be installed, such as pipelines, sockets, switches and other equipment.

[0056] After confirming that the size of the integrated sleeve 2 is correct, the integrated sleeve 2 is accurately installed and fixed to the building structure according to the position of the previous marking. In addition, the integrated sleeve 2 needs to be fixed to prevent the integrated sleeve 2 from shifting during subsequent construction.

[0057] S3, hoisting the row of pipes 1 into the integrated casing 2, and fixing and sealing the row of pipes 1.

[0058] Finally, the structural floor 3 is poured, and after the installation conditions of the row of pipes 1 are met, that is, after the structural floor 3 reaches the conditions for construction, the row of pipes 1 is hoisted using professional equipment until the row of pipes 1 reaches the predetermined position in the integrated casing 2. Then, the row of pipes 1 is pre-fixed, and after the position is confirmed, the fixing operation and the plugging operation are performed.

[0059] Of course, this embodiment does not limit the pre-fixing and fixing operations, and those skilled in the art may make changes according to actual conditions to achieve the same technical effect.

[0060] In this way, the embodiment of the present invention integrates the various sleeves in the prior art into an integrated sleeve 2, which can be directly inserted into all pipelines, so that the size of the integrated sleeve 2 is significantly larger than the size of the single pipeline, thereby improving the fault tolerance size of the integrated sleeve 2, thereby solving the cumulative error caused by too many sleeves during the installation process, and avoiding the problem of the pipeline and the sleeve being out of center. In addition, compared with the plugging of a single sleeve and a single pipeline, this embodiment reduces the number of pluggings by uniformly plugging the integrated sleeve 2, plugs in place at one time, and can also unify the plugging standards and plugging quality, thereby realizing standardized construction. The overall size of the integrated sleeve 2 is smaller than the overall size of each pipeline with a separate sleeve, which reduces the occupied space of the row of pipelines 1. The plugging and decorative cover 7 in the integrated sleeve 2 are also integrated, reducing the number of pluggings, plugging in place at one time, and decorating in place at one time, and the plugging standards and quality are unified, thereby realizing standardization. Compared with the traditional installation method, the installation process is greatly reduced, and the efficiency and quality of pipeline installation are improved.

[0061] Furthermore, in an optional embodiment, a predetermined spacing is provided between the inner wall of the integrated sleeve 2 and the outer wall of the row of pipes 1 along the length direction and the width direction of the integrated sleeve 2 .

[0062] Further, in an optional implementation, the predetermined spacing is between 40 mm and 60 mm.

[0063] Further, in an optional implementation, the step S2 includes:

[0064] S21, laying out the line according to the set reference coordinate points and horizontal height lines;

[0065] When measuring and laying out, the axis and elevation lines measured according to the project benchmark points are strictly used as the benchmark, that is, according to the benchmark coordinate points and horizontal height lines set by the project. These benchmark points are the basis for the entire construction accuracy control, ensuring that all subsequent construction work can be carried out in the correct direction and height.

[0066] In this way, the measurement accuracy can be guaranteed, because when constructing on high floors, any tiny measurement error may be magnified as the construction progresses, thus effectively avoiding the occurrence of cumulative errors in the actual construction process.

[0067] S22, placing the integrated casing 2 according to the line-laying position;

[0068] The construction personnel are required to check whether the size and height of the pre-installed integrated casing 2 are consistent with the design drawing requirements. This is to ensure that the integrated casing 2 and the rows of casings can be perfectly embedded to meet the needs of subsequent pipeline installation.

[0069] S23, fixing the integrated sleeve 2.

[0070] After confirming that the size of the integrated sleeve 2 is correct, the integrated sleeve 2 is accurately installed and fixed to the building structure according to the position of the previous marking.

[0071] It should be noted that during the subsequent steel bar binding, a special caretaker can be arranged to look after the integrated sleeve 2. During the steel bar binding operation, since there may be a lot of collisions and movements during this process, personnel can be assigned to look after the installed integrated sleeve 2. This ensures that the integrated sleeve 2 is not accidentally hit or displaced due to construction activities, so that subsequent pipelines can pass smoothly.

[0072] Further, in an optional implementation, step S3 includes:

[0073] S31, hoisting the single pipes in the row of pipes 1 in sequence;

[0074] S32, adjusting the distance between a single pipeline and the inner wall of the integrated casing 2 and the distance between each single pipeline, so that the row of pipelines 1 is located in the middle of the integrated casing 2.

[0075] The row of pipes 1 is hoisted using professional equipment until the row of pipes 1 reaches a predetermined position in the integrated casing 2. The row of pipes 1 is then temporarily fixed in preparation for subsequent precise adjustment.

[0076] It should be noted that the spacing between the individual pipes needs to be adjusted before the row of pipes 1 is fixed. At this stage, the technicians need to carefully adjust the distance between each pipe to ensure that there is enough space between them to avoid mutual interference or affect subsequent work such as insulation and maintenance.

[0077] At the same time, it is also necessary to ensure that the distance between each pipe and the inner wall of the integrated casing 2 is appropriate, ensure that the row of pipes 1 is located in the center of the integrated casing 2, and ensure the overall quality after installation.

[0078] Furthermore, in an optional implementation, the step S3 further includes:

[0079] S33, installing and fixing the row of pipes 1;

[0080] S34, after the row of pipes 1 is installed, the gap between the integrated sleeve 2 and the row of pipes 1 is sealed with fireproof material.

[0081] Furthermore, in an optional embodiment, the fireproof material at least includes a fireproof board 6, a non-combustible flexible material 5, and a fireproof mud 4.

[0082] Further, in an optional implementation, the step S34 includes:

[0083] S341, cutting the fireproof board 6 so that the outer dimension of the fireproof board 6 is larger than the outer dimension of the integrated sleeve 2;

[0084] S342, cutting a hole in the center of the fireproof board 6 for the row of pipes 1 to pass through;

[0085] S343, along the center line of the length direction of the fireproof board 6, the fireproof board 6 is divided into two small boards;

[0086] S344, merging the two small plates so that the holes after merging just surround the row of pipes 1;

[0087] S345, fix two small plates to the bottom of the structural floor 3.

[0088] First, cut the fireproof board 6, the overall size of which is larger than the size of the integrated sleeve 2, for example, each side can be 40mm, 50mm, 60mm, etc. Then cut out the hole through which the row of pipes 1 need to pass in the center of the fireproof board 6, and divide the fireproof board 6 into two along the center line in the length direction, and then align the two small boards through the row of pipes 1 and fix them to the lower skin of the structural floor 3.

[0089] Furthermore, in an optional implementation, the step S34 further includes:

[0090] S346, filling the non-combustible flexible material 5 into the gap between the integrated sleeve 2 and the row of pipes 1, and compacting it to the elevation of the floor decoration surface; the non-combustible flexible material 5 can be rock wool, glass wool, etc.

[0091] Furthermore, in an optional implementation, the step S34 further includes:

[0092] S347, apply the fireproof mud 4 on the top of the non-combustible flexible material 5, apply it to the top elevation of the integrated sleeve 2, and apply the surface of the fireproof mud 4 evenly and smoothly.

[0093] Furthermore, in order to ensure that the building is more beautiful as a whole after the construction is completed, a sleeve decorative cover 7 can be made according to the size of the integrated sleeve 2. The decorative cover 7 is made of flame-retardant or non-combustible material. The inner length and inner width of the decorative cover 7 are 2mm to 5mm larger than the outer length and outer width of the sleeve, respectively, to ensure that the decorative cover 7 can be buckled on the integrated sleeve 2.

[0094] The height of the decorative cover 7 is the height of the integrated sleeve 2 out of the decorative floor. Similarly, similar to the fireproof board 6, the hole through which the row of pipes 1 need to pass is cut out in the center of the decorative cover 7 and the decorative cover 7 is divided into two along the center line of the length direction, and then the two decorative covers 7 are passed through the row of pipes 1, aligned and tightly buckled on the integrated sleeve 2, so as to improve the overall appearance and quality of the row of pipes 1 passing through the floor.

[0095] In an embodiment of the present invention, the bottom of the integrated sleeve 2 is flush with the bottom of the structural floor 3, and the top of the integrated sleeve 2 exceeds the decorative floor by 20 mm. The top of the integrated sleeve 2 installed in the bathroom and kitchen should be 50 mm higher than the decorative floor. The material of the integrated sleeve 2 can be steel, and the minimum thickness of the steel is 1.6 mm.

[0096] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
