Description

Technical Field

[0001] This invention relates to the field of prefabricated building wall construction measurement, specifically a prefabricated building wall positioning and measurement device. Background Technology

[0002] Prefabricated building wall structure construction technology originates from the concept of industrialized production. Its core is to achieve building construction through the rapid on-site assembly of prefabricated components in factories. The development of this technology system can be traced back to the early 20th century. With the demand for standardized production brought about by the Industrial Revolution, the construction industry began to explore the path of component prefabrication. Currently, this technology has become a key path to promote the green transformation of the construction industry, especially in high-rise residential and public buildings.

[0003] The core of prefabricated wall construction lies in the integration of "design-production-assembly". In the design phase, BIM technology is used to break down components and optimize nodes, resolving pipeline collision issues. In the production phase, standardized molds and automated equipment are used in the factory to ensure component precision. In the assembly phase, rapid assembly is achieved through hoisting, alignment, and node connection. Its technological advantages are reflected in three aspects: first, quality controllability, as the factory environment avoids temperature and humidity fluctuations during on-site construction, significantly improving component strength consistency; second, increased efficiency, as prefabricated components can be produced in parallel, shortening on-site assembly time by 30%-50% compared to traditional construction; and third, environmental benefits, reducing on-site concrete pouring and steel reinforcement processing, significantly reducing dust and noise pollution. For example, some companies have achieved simultaneous progress in main structure and decoration work through a fully integrated construction model, shortening project delivery time by 40%.

[0004] Prefabricated building walls include: precast concrete shear walls, light steel keel partition wall systems, and ALC panel walls. As a core lateral force resisting component of modern high-rise buildings, the technical challenges lie in the splicing construction method.

[0005] 1. The distance between the joints of two adjacent walls and their "coplanarity" are difficult to control, requiring repeated instrument setup and calibration, which is time-consuming and labor-intensive.

[0006] 2. Temporary wall connections require the installation of multiple supporting steel pipes, which not only increases the workload but also delays the construction progress, indirectly further increasing construction costs. Summary of the Invention

Detailed Implementation

[0063] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0064] like Figures 1 to 11 As shown, a positioning and measuring device for prefabricated building walls is used during the construction of prefabricated building walls. This device enables the connection of two adjacent prefabricated walls and the detection and judgment of their coplanarity. The device includes a connecting seat structure 1 for placement between two adjacent prefabricated walls. One end of the connecting seat structure 1 is connected to the side wall of one of the adjacent prefabricated walls via a pre-embedded connector, and the other end is connected to the side wall of the other adjacent prefabricated wall via a movable connecting mechanism. After the first prefabricated building wall is constructed, subsequent adjacent prefabricated building walls are connected using this positioning and measuring device. Furthermore, a distance measuring mechanism for measuring the joint distance between two adjacent prefabricated walls is detachably connected to the connecting seat structure 1; a plane detection mechanism for detecting and measuring the coplanarity of two adjacent prefabricated walls is detachably connected to one side of the connecting seat structure 1; the distance measuring mechanism of this positioning measuring device measures the joint width (distance) of two adjacent prefabricated walls, thereby facilitating and quickly adjusting the joint width (distance) of two adjacent prefabricated walls to the design range; and the plane detection mechanism is used to detect and judge the "coplanarity" (the degree of "coplanarity" of the same side of two adjacent prefabricated walls), thereby saving construction time and reducing construction costs.

[0065] In the designed positioning and measuring device structure, the pre-embedded connector includes a pre-embedded connector 21 and a pre-embedded connector 22. The pre-embedded connector 22 is used to be pre-embedded in the side wall of one of the two adjacent prefabricated walls. The end of the pre-embedded connector 22 near the pre-embedded connector 21 is connected to the pre-embedded connector 21 through a connecting column. The end of the pre-embedded connector 21 away from the pre-embedded connector 22 is used to be flexibly connected to the movable connection mechanism through the connector structure 1. The pre-embedded connector of this positioning and measuring device is used to be pre-embedded in the side wall of one of two adjacent prefabricated walls (the side wall of the prefabricated wall installed first). It is also used to connect and limit the other prefabricated wall of the two adjacent prefabricated walls (for connection with the side wall of the prefabricated wall to be installed later) through a movable connecting mechanism. The positioning and measuring device connects the prefabricated wall to be installed first and the prefabricated wall to be installed later. The positioning and measuring device can measure (limit) the width (distance) of the joint (construction joint) of the two adjacent prefabricated walls, so as to facilitate quick adjustment, reduce tedious operations such as setting up instruments and repeated adjustments, and save manpower and material resources.

[0066] Furthermore, such as Figures 3 to 6As shown, the movable connection mechanism includes a limiting movable cylinder structure 31, which is hollow and is used to be pre-embedded in the side wall of one of two adjacent prefabricated walls (relative to the later constructed prefabricated wall); an internal expansion support structure is movably inserted through the limiting movable cylinder structure 31, which is movably inserted on the movable connecting shaft 32; a movable limiting hole is opened at the bottom end of the hollow cavity of the limiting movable cylinder structure 31, one end of the movable connecting shaft 32 is movably inserted in the movable limiting hole opened at the bottom end of the hollow cavity of the limiting movable cylinder structure 31, and the other end of the movable connecting shaft 32 movably passes through the side wall of the connecting seat structure 1 and is used for flexible movable connection with the pre-embedded connecting head 21. One end of the movable connecting shaft 32 of the movable connecting mechanism is used to pass through the limiting movable cylinder structure 31, which is embedded in the side wall of the prefabricated wall that is constructed later. By adjusting and controlling the internal expansion support structure set in the limiting movable cylinder structure 31 to "expand", the support is limited to the inner wall of the limiting movable cylinder structure 31. Thus, the prefabricated wall that is hoisted to the design position "in sequence" is connected by the positioning and measuring device to facilitate subsequent construction and ensure construction safety.

[0067] Furthermore, a movable rod 23 is provided at one end of the pre-embedded connector 21 near the movable connecting shaft 32, and the movable rod 23 is hollow; a movable ball head structure 231 is connected to the end of the movable rod 23 near the pre-embedded connector 21, and the movable ball head structure 231 is used to movably connect with the pre-embedded connector 21 through a ball seat; the end of the movable rod 23 away from the pre-embedded connector 21 is used to pass through the connecting seat structure 1; and the connecting seat structure 1 is used to connect with the pre-embedded connector 21 (to connect the pre-embedded connector 21). The movable connecting shaft 32 is connected and limited to the connecting seat structure 1 to facilitate the subsequent installation of the "distance measuring mechanism" and to serve as a reference reference. One end of the movable connecting shaft 32 passes through the connecting seat structure 1 and is used to pass through the hollow cavity of the movable rod 23. A deformation spring 321 is sleeved on one end of the movable connecting shaft 32 that passes through the hollow cavity of the movable rod 23. One end of the deformation spring 321 is used to connect with the movable connecting shaft 32, and the other end of the deformation spring 321 is used to connect with the inner wall of the hollow cavity of the movable rod 23. By allowing the movable connecting shaft 32 to pass movably through the connecting seat structure 1 and movably pass through the hollow cavity of the movable rod 23, and by using the deformation spring 321 to elastically connect the movable connecting shaft 32 and the movable rod 23, a relative range of motion is ensured between the movable connecting shaft 32 and the movable rod 23. Furthermore, the movable rod 23 is connected to the pre-embedded connector 21 via a ball joint structure, ensuring that the movable rod 23 has a certain range of motion relative to the pre-embedded connector 21, facilitating later adjustments to the relative position and distance between the "later" constructed prefabricated wall and the "first" constructed prefabricated wall.

[0068] Furthermore, such as Figures 4 to 7 As shown, the internal expansion support structure includes several movable support plates 33 movably disposed around the movable connecting shaft 32; one end of the movable support plate 33 near the movable connecting shaft 32 is movably connected to the movable connecting shaft 32 via a movable support member. The movable support plate 33 is movably connected to the movable connecting shaft 32 via the movable support member, and by adjusting and controlling the movable support member to "deploy," the movable support plate 33 is supported against the inner wall of the "cylinder" of the limiting movable cylindrical structure 31.

[0069] Meanwhile, each of the movable support components includes a movable scissor support rod a34 and a movable scissor support rod b35; the movable scissor support rod a34 and the movable scissor support rod b35 are movably crossed, and the middle of the movable scissor support rod a34 and the movable scissor support rod b35 are rotatably connected by a pin, that is, the movable scissor support rod a34 and the movable scissor support rod b35 are designed in a scissor support form to facilitate adjustment of the "movement".

[0070] Furthermore, the movable scissor support rod a34 is provided with a movable connecting block a341 at one end near the movable connecting shaft 32. The movable connecting block a341 is connected to the sliding sleeve 36 by a connecting screw. The sliding sleeve 36 is movably fitted onto the movable connecting shaft 32 (the sliding sleeve 36 is slidably set relative to the movable connecting shaft 32). A movable push cylinder is movably fitted onto one end of the sliding sleeve 36 near the connecting seat structure 1. One end of the movable push cylinder is used to connect with the sliding sleeve 36, and the other end of the movable push cylinder is used to connect to the rotating adjusting head 361 through a bearing. The rotating adjusting head 361 is used to movably fit onto the sliding sleeve 36. On the movable connecting shaft 32, the sliding sleeve 36 is moved by rotating the adjusting head 361; the movable connecting block a341 is provided with a movable sliding groove a, and a movable pin a is movably adapted in the movable sliding groove a. The movable pin a is used to be hingedly connected to the movable scissor support rod a34; a fixed connecting block a342 is provided at one end of the movable scissor support rod a34 near the supporting movable plate 33. The end of the movable scissor support rod a34 near the fixed connecting block a342 is hingedly connected to the fixed connecting block a342 through a hinge seat. The fixed connecting block a342 is connected to the supporting movable plate 33 by bolts.

[0071] Furthermore, the movable scissor support rod b35 is provided with a fixed connecting block b351 at one end near the movable connecting shaft 32 (the fixed connecting block b351 is located on the side of the movable connecting shaft 32 away from the movable connecting block a341). The end of the movable scissor support rod b35 near the fixed connecting block b351 is hinged to the fixed connecting block b351 via a hinge seat. The fixed connecting block b351 is connected to the fixed connecting disc 322 via bolts. The fixed connecting disc 322 is connected and fixed to the bottom end of the hollow cavity of the movable connecting shaft 32 near the limiting movable cylinder structure 31. The end of the movable scissor support rod b35 near the supporting movable plate 33 is provided with a movable connecting block b352. The movable connecting block b352 is connected to the supporting movable plate 33 via bolts. The movable connecting block b352 has a movable groove b, in which a movable pin b is movably adapted. The movable pin b is hinged to the movable scissor support rod b35.

[0072] In this embodiment, by using an "existing tool" (such as a wrench), the rotary adjustment head 361 is rotated around the movable connecting shaft 32 (the rotary adjustment head 361 and the movable connecting shaft 32 are threadedly connected). The rotary adjustment head 361 pushes the movable push cylinder and the sliding sleeve 36 connected to the other end of the movable push cylinder to "move". The "movement" of the sliding sleeve 36 drives the movable scissor support rod a34 and the movable scissor support rod b35 to rotate around the central pin and "unfold", thereby pushing the movable support plate 33 to support the inner wall of the "cylinder" of the limiting movable cylinder structure 31. The positioning and measuring device connects the two adjacent prefabricated walls. Furthermore, the movable connecting shaft 32 is "elastically connected" to the movable rod 23, and the movable rod 23 is "movably connected" to the pre-embedded connector 21 through a "spherical hinge structure," giving the movable connecting shaft 32 a certain "range of motion" relative to the "pre-embedded connector 21." This facilitates the later adjustment of the relative position and distance (relative position and distance at the joint) between the two prefabricated walls constructed "in sequence," ensuring that they meet the design and construction requirements.

[0073] Furthermore, such as Figure 1 , Figure 2 , Figure 8 , Figure 9As shown, the distance measuring mechanism includes a measuring connecting rod 4; one end of the measuring connecting rod 4 is detachably connected to the top or bottom end of the connecting seat structure 1; a measuring adjustment seat a41 is movably sleeved on the side of the measuring connecting rod 4 near the connecting seat structure 1, and a measuring adjustment seat b42 is movably sleeved on the side of the measuring connecting rod 4 away from the connecting seat structure 1, with the measuring adjustment seat a41 and the measuring adjustment seat b42 being movably arranged relative to each other; movable adjustment rods a411 are respectively provided on both sides of the end of the measuring adjustment seat a41 near the measuring adjustment seat b42, and the movable adjustment rods a411 are close to the measuring adjustment seat b42. One end of the joint seat a41 is hinged to the measuring connector a via a hinge seat. The measuring connector a is rotatably connected to the measuring adjustment seat a41 via a bearing. Movable adjustment rods b421 are respectively provided on both sides of the measuring adjustment seat b42 near the measuring adjustment seat a41. The ends of the movable adjustment rods b421 near the measuring adjustment seat b42 are hinged to the measuring connector b via hinge seats. The measuring connector b is rotatably connected to the measuring adjustment seat b42 via bearings. The ends of the movable adjustment rods a411 and b421 that are relatively close to each other are hinged together. A measuring scale 43 is bolted to the end of the movable adjustment rod b421 near the movable adjustment rod a411. A horizontal bubble tube is installed on the measuring scale 43, and the horizontal bubble tube contains liquid with bubbles for adjusting and judging the level.

[0074] In this embodiment, the measuring connecting rod 4 of the distance measuring mechanism is installed on the top or bottom of the connecting seat structure 1. In this embodiment, taking the top of the connecting seat structure 1 as an example, the measuring connecting rod 4 of the distance measuring mechanism is installed on the top of the connecting seat structure 1; and the measuring scale 43 is installed on one of the movable adjusting rods b421. After the bubble in the horizontal bubble tube is centered, the measuring scale 43 is fixed and stabilized on the movable adjusting rod b421. Then, the measuring adjusting seat b42 is rotated (using existing technology, such as a wrench) and moves downward around the measuring connecting rod 4, thereby causing the movable adjusting rods b421 on both sides to unfold outward toward their respective opposite sides of the two prefabricated walls (toward the "both sides" of the joint of the two prefabricated walls) under the "moving limit action" of their respective hinged movable adjusting rods a411. According to the designed "joint" width (distance) requirements, the movable adjusting rod b421 is brought closer to the measuring scale 43. One end rests against the side face of the "joint" of the prefabricated wall that was constructed and installed earlier, and the joint width (distance) is determined according to the reading on the measuring scale 43. To ensure relative accuracy of the readings, a vertical reference groove is provided in the vertical direction of the measuring connecting rod 4. When taking the reading, the angle from one end of the measuring scale 43, starting from the side end of the "joint" of the prefabricated wall that was installed first, to the vertical reference groove of the measuring connecting rod 4 is measured, and then multiplied by 2 to obtain the designed joint width (distance). Since the two sets of movable adjusting rods a411 and b421, which are "movably hinged" on both sides of the measuring connecting rod 4, are symmetrically arranged, the distance from the bottom end of the two movable adjusting rods b421 to the side end of the prefabricated wall that is in contact with the vertical reference groove of the measuring connecting rod 4 is equal to the distance from the vertical reference groove of the measuring connecting rod 4. Therefore, the width (distance) of the joint position of the two prefabricated walls required by the design is obtained by multiplying the reading from the end of the measuring scale 43 that is in contact with the wall to the vertical reference groove of the measuring connecting rod 4 by 2.

[0075] After adjusting the "position" of the measuring scale 43, the position of the next prefabricated wall to be constructed is adjusted by the lifting equipment and with the assistance of manual operation, so that the side of the joint end of the next prefabricated wall to be constructed contacts the end of the movable adjusting rod b421 on the nearest side, and the adjustment is stopped; this width (distance) is the width (distance) required by the design.

[0076] Furthermore, such as Figure 1 , Figure 2 , Figure 10 , Figure 11As shown, the positioning and measuring device is further equipped with a planar detection mechanism for detecting and judging the "coplanarity" of two adjacent prefabricated walls. This planar detection mechanism includes a planar detection connecting seat 5; the planar detection connecting seat 5 is detachably connected to one side of the connecting seat structure 1 via a connecting screw; a planar detection rotating rod 51 (both ends of the planar detection rotating rod 51 can be extended) is connected to the planar detection connecting seat 5 via a rotating pin, and the rotating pin is connected to the planar detection connecting seat 5 via a torsion spring; probe connectors 52 are respectively provided at both ends of the planar detection rotating rod 51; the end of the probe connector 52 near the planar detection rotating rod 51 is detachably connected to the planar detection rotating rod 51 via a fixed shaft; a detection contact probe 521 is installed and connected to the end face of the probe connector 52 near the prefabricated wall; a sensitive angle deflector 53 is provided above the rotating pin, and the sensitive angle deflector 53 is installed and fixed on the planar detection rotating rod 51.

[0077] In this embodiment, the plane detection rotating rod 51 of the plane detection mechanism is adjusted so that it is parallel to the vertical direction of the plane detection connecting seat 5 and close to one end face of the plane detection rotating rod 51. Then, the plane detection connecting seat 5 is installed on the connecting seat structure 1, so that the detection contact probes 521 connected to both ends of the plane detection rotating rod 51 respectively contact the side of the same side of the two prefabricated walls. The position of the prefabricated wall to be constructed is adjusted according to whether the sensitive angle deflector 53 deflects and the direction of deflection, so that the prefabricated walls constructed successively are "coplanar", that is, roughly on the same plane.

[0078] For example:

[0079] If the sensitive angle deflector 53 is deflected and is deflected to the relative "left", it means that the prefabricated wall on the relative right side has been deflected "backward" relative to the prefabricated wall on the left side. If the prefabricated wall on the left side is the wall to be constructed first, then the prefabricated wall on the relative right side needs to be moved "forward". When the sensitive angle deflector 53 is centered, it means that the two prefabricated walls are now roughly horizontal and coplanar.

[0080] Assuming the sensitive angle deflector 53 is offset and offset to the relative "right", it means that the prefabricated wall on the relative right side has been offset "forward" relative to the prefabricated wall on the left side. If the prefabricated wall on the left side is the wall that was constructed first, then the prefabricated wall on the relative right side needs to be moved "backward". When the sensitive angle deflector 53 is centered, it means that the two prefabricated walls are now roughly horizontal and coplanar.

[0081] After adjusting the positions of the two prefabricated walls, the next prefabricated wall to be constructed is positioned and stabilized. The distance measuring mechanism and the plane detection mechanism of the positioning measuring device are then removed from the connecting seat structure 1 of the positioning measuring device and recycled for reuse. Subsequently, the joints of the two prefabricated walls are constructed, and then the next prefabricated wall is constructed in sequence.
