Description

Technical Field

[0001] The present application belongs to the technical field of prefabricated building prefabricated block masonry construction, and specifically relates to a BIM-based prefabricated block groove-free masonry method. Background Art

[0002] Wall masonry is a common construction method in building construction. Currently, there are two main forms of opening pipeline ducts in walls: one is to use bricks to build the wall on site, and at the same time reserve positions and spaces for the laid pipelines, and stagger the structures for construction work. This method separates the entire wall and is simple and easy to operate, but it has an adverse effect on the strength of the wall structure. Even if the pipeline duct is subsequently transitionally connected, it still affects the strength of the entire wall; the second is to use an integral prefabricated wall, and reserve pipeline ducts on the wall during the prefabrication stage, without the need for on-site processing, but this method has high requirements for on-site hoisting equipment and working space, and is not widely applicable. Summary of the invention

[0003] The purpose of this application is to provide a BIM-based prefabricated block groove-free masonry method, which solves the problem of low wall strength or high operation requirements caused by opening pipeline grooves in existing masonry walls.

[0004] The purpose of this application is achieved through the following technical solutions:

[0005] A BIM-based prefabricated block groove-free masonry method comprises the following steps:

[0006] Step a, establishing models of standard prefabricated blocks, slotted prefabricated blocks and pipelines for masonry based on BIM, and optimizing the layout of the pipelines;

[0007] Step b, conducting in-depth design of slotted prefabricated blocks based on the BIM model;

[0008] Step c: Install the pipeline based on the BIM model and temporarily fix the pipeline;

[0009] Step d, using standard prefabricated blocks and slotted prefabricated blocks to alternately build the wall, the pipeline troughs of the upper and lower adjacent slotted prefabricated blocks are located opposite to each other, and the pipeline troughs form a space for accommodating pipelines in the vertical direction;

[0010] Step e: filling the gap between the slotted prefabricated block and the pipeline with mortar.

[0011] Furthermore, the slotted prefabricated block comprises a first side opening block, a pipeline groove is formed between the first side opening groove on one side of the first side opening block and an adjacent standard prefabricated block, and the other side of the first side opening block is fitted with the adjacent standard prefabricated block.

[0012] Furthermore, the slotted prefabricated block includes a first side opening block and a second side opening block, a pipeline groove is formed between the first side opening groove on one side of the first side opening block and the second side opening groove on one side of the second side opening block, the other side of the first side opening block is fitted with an adjacent standard prefabricated block, and the other side of the second side opening block is fitted with an adjacent standard prefabricated block.

[0013] Furthermore, the thickness of the side opening blocks is the same as that of the standard prefabricated blocks; and the shape of the side opening grooves is U-shaped.

[0014] Furthermore, the slotted prefabricated block includes an end face opening block and an end face blocking block, a pipeline groove is formed between the end face opening groove at one end face of the end face opening block and the end face blocking block, and the end face opening block and the end face blocking block are both located between the left and right standard prefabricated blocks.

[0015] Furthermore, an end face opening block and an end face blocking block are provided between the standard prefabricated blocks of the upper layer and the lower layer, and the end face opening block and the end face blocking block are opposite to each other in left and right positions.

[0017] Furthermore, the end face opening block and the end face shielding block are connected via a U-shaped clip at the top.

[0018] Furthermore, in the step d, when laying the upper slotted prefabricated blocks, the auxiliary positioning sleeve is placed and clamped in the pipeline trough of the upper layer. When the upper slotted prefabricated blocks are in place, the auxiliary positioning sleeve is simultaneously inserted into the pipeline trough of the lower layer. The auxiliary positioning sleeve is then used to ensure the verticality of the pipeline trough in the vertical direction, and at the same time serves as the reference position for the laying of the upper slotted prefabricated blocks and the standard prefabricated blocks.

DETAILED DESCRIPTION

[0028] The following non-limiting examples are provided to illustrate the present application.

[0029] Example 1

[0030] refer to Figure 1 As shown, a BIM-based prefabricated block groove-free masonry method includes the following steps:

[0031] Step a: Establish models of standard prefabricated blocks, slotted prefabricated blocks and pipelines for masonry based on BIM, and optimize the layout of the pipelines.

[0032] Step b: carry out in-depth design of the slotted prefabricated blocks based on the BIM model, specifically selecting the slotted prefabricated blocks according to the wall thickness (100 / 200mm).

[0033] Step c: installing the pipeline 4 based on the BIM model and temporarily fixing the pipeline 4.

[0034] Step d, using standard prefabricated blocks 1 and slotted prefabricated blocks 2 to alternately build the wall, with the construction being carried out layer by layer from bottom to top. The two types of prefabricated blocks are constructed together and arranged alternately, which ensures the integrity of the built wall and improves the strength and quality of the final wall.

[0035] The pipeline grooves 3 of the upper and lower adjacent slotted prefabricated blocks 2 are located opposite to each other in the upper and lower directions, and the pipeline grooves 3 form a space for accommodating the pipelines 4 in the vertical direction, thereby completing the embedding and placement of the pipelines in the wall.

[0036] Step e, using mortar to fill the gap between the slotted prefabricated block 2 and the pipeline 4, so that the pipeline is cast in the wall together, which not only avoids the formation of wall cavities and ensures the structural quality of the wall, but also realizes the complete wrapping of the pipeline in the wall and protects the pipeline.

[0037] The length of the standard prefabricated block 1 is 600 mm, and the thickness is selected as 100 / 200 mm as needed. For fewer pipelines, the slotted prefabricated block 2 includes a first side opening block 201 with a length of 600 mm. The thickness of the first side opening block 201 is the same as that of the standard prefabricated block 1 (100 / 200 mm), ensuring that the two prefabricated blocks form a wall with uniform thickness.

[0038] A pipeline groove 3 is formed between the first side opening groove 202 on one side of the first side opening block 201 and the adjacent standard prefabricated block 1. The groove shape of the first side opening groove 202 is U-shaped. The adjacent standard prefabricated block 1 closes the first side opening groove 202 to form a space for accommodating the pipeline 4.

[0039] The other side of the first side opening block 201 is fitted with the adjacent standard prefabricated block 1, that is, both sides of the first side opening block 201 of each layer of this embodiment are standard prefabricated blocks 1. The standard prefabricated blocks 1 and the first side opening block 201 are arranged in an upper and lower staggered manner and are built together to form a whole.

[0040] In step d, when laying the upper slotted prefabricated block 2, the auxiliary positioning sleeve 5 is placed and stuck in the pipeline trough 3 of the upper layer. When the upper slotted prefabricated block 2 is in place, the auxiliary positioning sleeve 5 is inserted into the pipeline trough 3 of the lower layer at the same time. The verticality of the pipeline trough 3 in the vertical direction is ensured by the auxiliary positioning sleeve 5. At the same time, the positioned position is used as the laying reference position of the upper slotted prefabricated block 2 and the standard prefabricated block 1.

[0041] The auxiliary positioning sleeve 5 includes a pipeline trough profile sleeve 501 with a U-shaped cross-section. The pipeline trough profile sleeve 501 is higher than the layer height of the masonry prefabricated block, ensuring that the pipeline trough profile sleeve 501 can be clamped in the pipeline troughs 3 of two different layers above and below. The pipeline trough profile sleeve 501 is provided with a lateral opening 502 to achieve the placement of the auxiliary positioning sleeve 5 and avoid the interference of the pipeline 4 with the auxiliary positioning sleeve 5. The top of the pipeline trough profile sleeve 501 is integrally provided with a top supporting edge 503 that extends outward horizontally. The top supporting edge 503 is placed on the slotted prefabricated block to prevent it from falling downward.

[0042] Example 2

[0043] refer to Figure 2 As shown, a BIM-based prefabricated block groove-free masonry method, for more densely packed pipelines, the grooved prefabricated block 2 of this embodiment includes a first side opening block 201 with a length of 600 mm and a second side opening block 203 with a length of 250 mm, so as to extend the width of the pipeline trough, and the thickness of the first side opening block 201 and the second side opening block 203 are the same as that of the standard prefabricated block 1 (100 / 200 mm).

[0044] A pipeline groove 3 is formed between the first side opening groove 202 on one side of the first side opening block 201 and the second side opening groove 204 on one side of the second side opening block 203. The groove shapes of the first side opening groove 202 and the second side opening groove 204 are U-shaped, and the two side opening grooves are relatively self-sealed to form a space for accommodating the pipeline 4.

[0045] The other side of the first side opening block 201 is fitted with the adjacent standard prefabricated block 1, and the other side of the second side opening block 203 is fitted with the adjacent standard prefabricated block 1, that is, the slotted prefabricated block 2 of each layer of this embodiment includes two side opening blocks between the left and right standard prefabricated blocks 1. The two side opening blocks form the whole of the slotted prefabricated block and the standard prefabricated blocks 1 in an arrangement manner of staggered up and down in sequence, and are built together to form a whole, and at the same time, the first side opening block 201 and the second side opening block 203 are also arranged in a staggered manner up and down in sequence.

[0046] The rest is the same as in Example 1.

[0047] Example 3

[0048] A BIM-based prefabricated block groove-free masonry method, for a 200 mm thick wall, the grooved prefabricated block 2 includes an end opening block 205 with a length of 600 mm and an end blocking block 207 with a length of 600 mm, the sum of the thickness of the end opening block 205 and the end blocking block 207 must be equal to the wall thickness (i.e., the thickness of the standard prefabricated block 1), preferably both are 100 mm, to ensure that the grooved prefabricated block 2 formed by the two panels has the same thickness as the wall.

[0049] A pipeline groove 3 is formed between the end surface opening groove 206 of one end surface of the end surface opening block 205 and the end surface blocking block 207. The groove shape of the end surface opening groove 206 is U-shaped. The end surface blocking block 207 closes the end surface opening groove 206 to form a space for accommodating the pipeline 4. Figure 4 As shown, the end opening block 205 and the end shielding block 207 are connected by a U-shaped clip 209 at the top to ensure that the slotted prefabricated block structure is reliable. The U-shaped clip is formed by bending the waste steel bar residue. A hole with a depth of 8-10 cm is drilled at the location where the U-shaped clip is to be installed. The U-shaped clip is wrapped with mortar and inserted into the hole, and then the masonry is continued.

[0050] The end face opening block 205 and the end face blocking block 207 are both located between the standard prefabricated blocks 1 on the left and right. The end face opening block 205 and the end face blocking block 207 are arranged between the standard prefabricated blocks 1 on the upper and lower layers, that is, the slotted prefabricated blocks of each layer include the end face opening block 205 and the end face blocking block 207. The end face opening block 205 and the end face blocking block 207 are opposite to each other in left and right positions, that is, there is no positional misalignment between the two. The end face opening block 205 and the end face blocking block 207 form the whole of the slotted prefabricated block, and the standard prefabricated blocks 1 are arranged in an upper and lower staggered manner, and are built together to form a whole, which is similar to the arrangement of Examples 1 and 2.

[0051] The rest is the same as in Example 1.

[0052] Example 4

[0053] refer to Figure 3 As shown, a BIM-based prefabricated block slot-free masonry method, for a 200 mm thick wall, the slotted prefabricated block 2 also includes a side supplementary block 208 with a length of 300 mm, and the side supplementary block 208 has the same thickness as the end opening block 205.

[0054] End face opening blocks 205, end face blocking blocks 207 and side supplementary blocks 208 are arranged between the standard prefabricated blocks 1 of the upper layer, and the end face opening blocks 205 are arranged between the two end face blocking blocks 207, and the side supplementary blocks 208 are arranged between the side of the end face opening block 205 and the adjacent standard prefabricated blocks 1. That is, the upper layer occupies the space of two standard prefabricated blocks 1 by using the end face opening blocks 205, the end face blocking blocks 207 and the side supplementary blocks 208, and the three panels are interlocked with each other.

[0055] An end face opening block 205 and an end face shielding block 207 are arranged between the standard prefabricated blocks 1 of the lower layer, and the end face opening block 205 and the end face shielding block 207 are opposite to each other in left and right positions, that is, there is no positional misalignment between the two, and the lower layer is the same as that of Embodiment 3. This method facilitates the end face opening block 205 to keep its position unchanged, and only the shielding blocks and supplementary blocks of the side and end faces need to be adjusted according to different layers.

[0056] The rest is the same as in Example 3.

In the scheme of this application, each selected example can be arbitrarily combined with any other basic examples and selected examples.
