Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a locator beam sleeve based on BIM technology and a construction method thereof. Background Art

[0002] Pre-embedding beam casing differs from pre-embedding casing in other locations, such as through walls and floor slabs. It must be installed correctly the first time. Improper embedding or quality issues will be difficult to remedy, directly impacting the quality of subsequent pipe installation. Therefore, the quality of pre-embedding beam casing has a significant impact on the overall quality of the installation. However, the casing and beam formwork are often secured within the rebar cage using a crisscross pattern. This method is cumbersome, often requiring multiple personnel to operate, increasing labor costs, and can easily lead to potential leakage between the casing and beam formwork, as well as casing deviation during concrete pouring.

[0003] To this end, Chinese patent application CN221941927U discloses a beam-penetrating sleeve. This sleeve features an internal connector structure that allows it to be fixed to the beam casting formwork, ensuring precise positioning. This design allows for single-step pre-embedding, ensuring greater accuracy and improving construction efficiency compared to traditional methods.

[0004] While using only connectors to connect the beam sleeves improves installation accuracy, there's still a risk of grout leakage at the connection between the connector and the beam. Furthermore, bolts are required to connect the connector to the beam, and if holes are drilled in the beam before installation, the positioning accuracy of the installation datum must be ensured. If the embedded sleeves are moved to the datum before installation, vibrations generated during the drilling process can affect the positioning accuracy of the embedded sleeves. Summary of the Invention

The locator, support beam and top support mechanism are used to solve the problem that the traditional beam sleeve will affect the positioning accuracy during the construction process.

[0006] In order to solve the problems of the existing technology, the present invention provides a locator beam sleeve based on BIM technology, and locators are installed at both ends of the sleeve; a circular positioning groove cooperating with the locator is opened on the support beam; and a supporting mechanism for pushing the locator into the positioning groove is provided in the sleeve.

[0007] Preferably, the positioner includes a connecting member and a sealing member; the connecting member is a cylindrical shell with one end open; and the sealing member is slidably arranged on the connecting member.

[0008] Preferably, a sealing ring is provided on the sealing member, and when the sealing member is connected to the support beam, the sealing ring abuts against the side wall of the support beam.

[0009] Preferably, the supporting mechanism includes a mounting frame and a supporting assembly; the mounting frame is detachably arranged in the support beam; there are two groups of supporting assemblies, and the two groups of supporting assemblies are respectively located on both sides of the mounting frame; after the sleeve is installed on the support beam, the supporting assembly presses the locator into the positioning groove.

[0010] Preferably, the supporting assembly includes a gas spring and a support ring; the gas spring is arranged on the mounting frame; and the piston rod of the gas spring is connected to the support ring.

[0011] Preferably, an internal support assembly is provided on the mounting frame, and the internal support assembly includes a mounting rod and a bracket; the mounting rod is connected to the mounting frame; the bracket is sleeved on the mounting rod, and at least three push rods are slidably installed on the bracket; each push rod is provided with an elastic member, and the two ends of the elastic member are respectively connected to the push rod and the bracket.

[0012] Preferably, a roller is rotatably provided at the end of the push rod.

[0013] Preferably, the sealing member is provided with at least two lugs, and each lug is provided with a positioning hole.

[0014] Preferably, the positioner is made of PE material.

[0015] A construction method for beam sleeves comprises the following steps:

[0017] S2. Install the positioner on the casing;

[0018] S3. Install the sleeve with the positioner installed on the support beam and ensure that the positioner is accurately connected to the positioning groove;

[0019] S4. Fix the locator to the support beam and pour concrete after passing the inspection.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention realizes the function of accurately installing the beam-penetrating sleeve through the positioner, the support beam and the top support mechanism, and improves the stability of the sleeve during the construction process by plugging and matching the positioner and the positioning groove. And by using the setting of the top support mechanism, the positioner and the positioning groove can be stably matched, the sealing of the connection can be improved, and the problem of leakage can be avoided while ensuring the positioning accuracy. It solves the problem that the traditional beam-penetrating sleeve will affect the positioning accuracy during the construction process. The present invention adopts BIM technology for precise positioning. After BIM modeling of the main structure of the building in advance, the horizontal pipeline system is drawn in the area where the beam is allowed to pass according to the design beam-penetrating requirements. The size and distance of the main beam and the secondary beam, the required space for pipeline installation, the required space for valve installation, the required pipeline slope, the end positioning and other factors are comprehensively considered. The specifications of the structural beams that cannot meet the design beam-penetrating requirements or the structural secondary beams that do not need to be passed through are adjusted, and the design institute is coordinated to conduct a structural review. While meeting the structural requirements, the position of the pipeline passing through the beam is determined.

[0022] 2. The present invention realizes the function of improving the installation portability of the sleeve through the split design of the connector and the seal. When installing the sleeve, the seal is slid to separate the seal from the inner wall of the support beam to avoid the seal from obstructing the support beam. After the connector is matched with the positioning groove, the seal is pushed to match the seal with the positioning groove, and then the sleeve is fixed and installed. This fixing method effectively solves the phenomenon of sleeve leakage and deviation during concrete pouring, and solves the problem of sleeve blocking, greatly reducing labor costs, and the operation process is simple, fast and more efficient.

[0023] 3. This invention utilizes a mounting bracket and a support assembly to enhance the stability of the connection between the locator and the support beam. When the sleeve is installed on the support beam, the pressure provided by the support assembly increases the pressure between the locator and the support beam, thereby enhancing the seal at the connection between the locator and the support beam. Combined with the seal and sealing ring, a multi-layered seal is achieved, further preventing grout leakage after grouting. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Reference Figures 1-4 : The locator based on BIM technology passes through the beam sleeve, and a locator 1 is installed at both ends of the sleeve; a circular positioning groove 21 that cooperates with the locator 1 is opened on the support beam 2; a supporting mechanism 3 for pushing the locator 1 into the positioning groove 21 is provided in the sleeve.

[0037] The present invention realizes the function of accurately installing the beam-penetrating sleeve through the positioner 1, the support beam 2 and the supporting mechanism 3, and utilizes the plug-in cooperation of the positioner 1 and the positioning groove 21 to improve the stability of the sleeve during the construction process. And by utilizing the setting of the supporting mechanism 3, the positioner 1 can be stably matched with the positioning groove 21, the sealing of the connection can be improved, and the problem of leakage can be avoided while ensuring the positioning accuracy. The problem that the traditional beam-penetrating sleeve will affect the positioning accuracy during the construction process is solved. The present invention adopts BIM technology for precise positioning. After BIM modeling of the main structure of the building in advance, the horizontal pipeline system is drawn in the area where the beam is allowed to pass according to the design beam-penetrating requirements. The size and distance of the main beam and the secondary beam, the required space for pipeline installation, the required space for valve installation, the pipeline slope requirement, the end positioning and other factors are comprehensively considered. The specifications of the structural beams that cannot meet the design beam-penetrating requirements or the structural secondary beams that do not need to be passed through are adjusted, and the design institute is coordinated to conduct a structural review. While meeting the structural requirements, the position of the pipeline through the beam is determined.

[0038] According to the construction drawings, the thickness of the support beam 2 is checked to determine the length of the sleeve, and the sleeve diameter is selected in accordance with the relevant specifications. The sleeve is made of steel pipe. Mark and locate the sleeve position on both sides of the support beam 2, draw a cross line, and open a positioning groove 21 according to the cross line. After the overhead beam reinforcement is tied, the two positioners 1 are respectively installed on the two ends of the sleeve. Then install the sleeve on the support beam 2, and adjust the sleeve horizontally or according to the slope until the axis of the sleeve is collinear with the axis of the positioning groove 21. At this time, the supporting force provided by the supporting mechanism 3 enables the positioner 1 to be stably plugged into the positioning groove 21. This installation method effectively solves the problem of sleeve leakage and deviation during concrete pouring, and solves the problem of sleeve sealing, which greatly reduces labor costs, and the operation process is simple, fast, and more efficient. During construction, the specifications and spacing of the primary and secondary beams, the pipeline installation space and other factors are comprehensively considered, and BIM technology is used to accurately locate the beam sleeve, which is convenient for construction.

[0039] Reference Figure 1 、 Figure 3-Figure 6 : The positioner 1 includes a connecting member 11 and a sealing member 12; the connecting member 11 is a cylindrical shell with one end open; the sealing member 12 is slidably arranged on the connecting member 11.

[0040] The present invention achieves improved portability during sleeve installation through the separate design of the connector 11 and the seal 12. When installing the sleeve, the seal 12 is slid apart from the inner wall of the support beam 2 to prevent the seal 12 from obstructing the support beam 2. This method utilizes BIM technology for precise positioning, installing the embedded sleeve with the sleeve locator and then securing it to the beam formwork. This fixing method effectively solves the problems of sleeve leakage and deviation during concrete pouring, while also solving the problem of sleeve blocking. It significantly reduces labor costs, and the operation process is simple, fast, and more efficient. The connector 11 is provided with a retaining ring 111 and a snap ring 112, with the seal 12 positioned between the retaining ring 111 and the snap ring 112. The snap ring 112 is an elastic protrusion. When installing the seal 12 on the connector 11, the seal 12 is pushed in from the side of the snap ring 112. The snap ring 112 deforms under the extrusion, completing the assembly of the seal 12 and the connector 11. After the connector 11 is matched with the positioning groove 21, the seal 12 is pushed to match the seal 12 with the positioning groove 21, and then the sleeve is fixed and installed. According to the sleeve position determined by the BIM drawing, use a marker to mark symmetrically on the support beam 2 where the sleeve needs to be installed, draw a cross positioning line, mark the center point of the cross line with a nail, and then open the positioning groove 21. After the template of the first flow section is safely fixed, pull the line to keep the sleeve position in the same straight line, and use nails to mark the horizontal position on both sides of the sleeve to be installed according to the pulled line. After the overhead beam reinforcement is tied, place the sleeve of the corresponding specifications according to the construction drawing, and put the matching locator 1 on both ends of the sleeve, and plug it into the sleeve through the connector 11. According to the design requirements, ensure the straightness of the two ends of the locator 1, the slope and positioning are accurate, and keep the sleeve position in the same straight line. When all the beam reinforcement in a certain area is tied, the embedded sleeves are also placed, and relevant personnel are organized to check one by one to see if there are any missed or misplaced sleeves.

[0041] Reference Figure 4 and Figure 6 : A sealing ring 121 is provided on the sealing member 12. When the sealing member 12 is connected to the support beam 2, the sealing ring 121 abuts against the side wall of the support beam 2.

[0042] The present invention utilizes sealing ring 121 to improve the sealing performance at the interface between seal 12 and support beam 2. Sealing ring 12 is made of rubber and is connected to it, allowing it to move with the movement of sealing ring 121. During sleeve installation, seal 12 is pushed, which in turn drives sealing ring 121. Sealing ring 121 is then connected to support beam 2. The deformability of sealing ring 121 improves the sealing performance of the connection between them.

[0043] Reference Figure 4 and Figure 7 : The supporting mechanism 3 includes a mounting frame 31 and a supporting assembly 32; the mounting frame 31 can be detachably arranged in the support beam 2; there are two groups of supporting assemblies 32, and the two groups of supporting assemblies 32 are respectively located on both sides of the mounting frame 31; after the sleeve is installed on the support beam 2, the supporting assembly 32 presses the locator 1 into the positioning groove 21.

[0044] The present invention utilizes mounting bracket 31 and support assembly 32 to enhance the connection stability between positioner 1 and support beam 2. When the sleeve is installed on support beam 2, the pressure provided by support assembly 32 increases the pressure between positioner 1 and support beam 2, thereby enhancing the seal at the connection between positioner 1 and support beam 2. This, combined with seal 12 and sealing ring 121, creates a multi-layered seal, further preventing grout leakage after grouting.

[0045] Reference Figure 7 and Figure 8 : The supporting assembly 32 includes a gas spring 321 and a support ring 322; the gas spring 321 is arranged on the mounting frame 31; the piston rod of the gas spring 321 is connected to the support ring 322.

[0046] The present invention achieves the function of applying pressure to the connector 11 through the gas spring 321 and the support ring 322. When installing the sleeve, the sleeve is first pushed into the support beam 2, and the gas spring 321 contracts under the pressure. This action continues until the sleeve moves to the positioning groove 21, and the axis of the sleeve is collinear with the axis of the positioning groove 21. The gas spring 321 has a tendency to extend, and the support ring 322, under the elastic force provided by the gas spring 321, presses the connector 11 into the positioning groove 21. The pressure applied by the support ring 322 on the connector 11 improves the contact tightness between the connector 11 and the support beam 2.

[0047] Reference Figure 7 、 Figure 9 and Figure 10 : An internal support assembly 33 is provided on the mounting frame 31, and the internal support assembly 33 includes a mounting rod 331 and a bracket 332; the mounting rod 331 is connected to the mounting frame 31; the bracket 332 is sleeved on the mounting rod 331, and at least three top rods 3321 are slidably installed on the bracket 332; each top rod 3321 is provided with an elastic member 3322, and the two ends of the elastic member 3322 are respectively connected to the top rod 3321 and the bracket 332.

[0048] The present invention achieves the function of installing the mounting frame 31 inside the sleeve through the mounting rod 331, the bracket 332, the push rod 3321 and the elastic member 3322. The cooperation between the push rod 3321 and the elastic member 3322 can keep the axis of the support ring 322 colinear with the axis of the sleeve, and can adapt to sleeves of different inner diameters. The multiple push rods 3321 are distributed in a circular array about the axis of the mounting rod 331. The operator pushes the mounting frame 31 into the sleeve, and under the action of squeezing, the elastic member 3322 on the push rod 3321 contracts. Under the support of the multiple push rods 3321, the axis of the mounting rod 331 on the mounting frame 31 is close to the axis of the sleeve. Even if it deviates under the action of gravity, the elastic support of the multiple elastic members 3322 will keep the distance between the two within the threshold. This enables the support ring 322 to provide a relatively stable pressing force.

[0049] Reference Figure 7 、 Figure 9 and Figure 10 : A roller 3323 is rotatably provided at the end of the top rod 3321.

[0050] The present invention utilizes rollers 3323 to improve the portability of the mounting frame 31 within the casing. When the mounting frame 31 is moved, the end of the push rod 3321 compresses against the inner wall of the casing. Therefore, rollers 3323 are provided at the end of the push rod 3321. When the mounting frame 31 is moved, the sliding friction between the push rod 3321 and the casing is replaced by rolling friction between the rollers 3323 and the inner wall of the casing. This not only improves the portability of the mounting frame 31 but also reduces wear on the casing and push rod 3321, thereby increasing the service life of the casing and the supporting mechanism 3.

[0051] Reference Figure 2-Figure 4 : The sealing member 12 is provided with at least two ear plates 122 , and each ear plate 122 is provided with a positioning hole 1221 .

[0052] The present invention realizes the function of connecting the support beam 2 and the seal 12 by screws through the ear plate 122 and the positioning hole 1221, thereby improving the connection stability between the locator 1 and the support beam 2. When fixing the locator 1, first make the connecting member 11 and the seal 12 cooperate with the positioning groove 21 on the support beam 2 to form a preliminary fixation. Then, according to the previous process, the horizontal position and elevation are determined, and the screws are passed through the positioning hole 1221 on the ear plate 122 to connect the seal 12 and the support beam 2 to complete the stable installation of the locator 1. After the construction personnel have completed the installation, they will strictly follow the three-inspection system for acceptance, and then the professional construction foreman will conduct the final process acceptance together with the supervisor and relevant personnel. After the acceptance is qualified, a special person will be sent to patrol and protect when pouring concrete. After the concrete solidifies, the operator will remove the support beam 2 and the locator 1 to obtain the finished product.

[0053] Reference Figure 4-Figure 6 : The positioner 1 is made of PE material.

[0054] The present invention achieves a green and environmentally friendly effect through the positioner 1 made of PE material. The positioner 1 made of PE material is durable and crack-resistant. The green and environmentally friendly effect is achieved through its recyclable nature. Compared with traditional technology, the construction cost of welding processing is high and it pollutes the environment. The use of the positioner 1 for fixed support can improve the installation accuracy and construction quality, and it is green, environmentally friendly and pollution-free. Check the thickness of the support beam 2 according to the construction drawings to determine the sleeve length, select the sleeve diameter according to relevant specifications, and the sleeve is made of steel pipe. Mark and locate the position of the positioning groove 21 on both sides of the support beam 2, draw a cross line, and after the overhead beam reinforcement is tied, put the two beam-penetrating sleeve positioners on both ends of the embedded pipe fittings, align the sleeve horizontally or according to the slope, and fix the sleeve positioner with screws on the symmetrical positioning line of the template.

[0055] Reference Figure 1-Figure 5 :A construction method for beam sleeve, comprising the following steps:

[0056] S1. Determine the installation position of the sleeve on the support beam 2 and open a positioning groove 21 at the installation position;

[0057] S2. Install the positioner 1 onto the casing;

[0058] S3, installing the sleeve with the positioner 1 onto the support beam 2, and ensuring that the positioner 1 is accurately docked with the positioning groove 21;

[0059] S4. Fix the positioner 1 to the support beam 2 and pour concrete after passing the inspection.

[0060] Construction preparation: After pre-BIM modeling of the main building structure, the horizontal piping system is mapped within the permitted beam penetration area according to the design beam penetration requirements. Taking into account factors such as the size and distance of the main and secondary beams, the required space for pipe installation, the required space for valve installation, the required pipe slope, and the terminal positioning, adjustments are made to the specifications of structural beams that do not meet the design beam penetration requirements or those that do not require penetration. Coordinate with the design institute for structural review to determine the pipe beam penetration locations while meeting the structural requirements. Construction can only begin after the specifications and locations of the reserved casings have been confirmed by the design institute's structural review. Technical briefing: Labor, equipment, and related pre-embedded and reserved materials are prepared according to the construction drawing requirements and on-site construction conditions. Construction plans and technical briefings are also prepared in accordance with the design, national standards, and company technical requirements. Casing positioning: Based on the pre-embedded casing positions determined on the BIM drawings, symmetrically mark the support beams where the casings are to be installed with a marker, draw a cross-shaped positioning line, and mark the center of the cross-line with a nail.

[0061] The above embodiments only express one or several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they should not be understood as limiting the scope of the present invention. It should be pointed out that, for those skilled in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the appended claims. After the template of a flow section is securely fixed, a through line is pulled to keep the sleeve position in the same straight line. According to the pulled through line, the horizontal position marks are made with nails on both sides of the sleeve to be installed. After the overhead beam reinforcement is tied, the sleeve of the corresponding specifications is placed according to the construction drawings, and the matching beam sleeve locator is placed on both ends of the reserved pipe. According to the design requirements, the straightness of the two ends of the sleeve locator is ensured, and the slope and positioning are accurate, and the sleeve position is kept in the same straight line. When all the beam reinforcements in a certain area are tied, the embedded sleeves are also placed, and the relevant personnel are organized to check one by one to see if there are any missed or misplaced sleeves. Initial Fixing: Determine the horizontal position and elevation based on the previous steps, then screw the beam locator hooks to the formwork for initial fixation. Inspection: After initial fixation, construction personnel will promptly check the sleeve position and elevation for correctness. Reinforcement: After verifying the sleeve position and elevation, secure the sleeve locator to the beam formwork with screws. After installation, construction personnel will conduct a strict three-inspection inspection and acceptance inspection. A professional construction foreman, along with the supervisor and relevant personnel, will then conduct a final inspection. Upon successful acceptance, a dedicated personnel will be assigned to conduct patrols and protection during the concrete pouring process.

[0062] To ensure construction quality, prior to construction, all construction management personnel and team members must receive training to familiarize themselves with the technical requirements for pre-embedded casing through beams and master the construction techniques and operating procedures. During construction, every process step must be carefully controlled, including line positioning, casing placement, inspection, locator fixation, and finished product protection. Standards and inspections must be implemented at every step to ensure comprehensive construction quality control, with a focus on process quality control. A system of construction technical briefings must be adhered to, with construction personnel strictly following technical specifications and welding process implementation instructions. Through these briefings, quality objectives, quality standards, quality assurance measures, and the technical responsibility system at all levels must be implemented. Required testing and inspections during the construction process must be carried out promptly. Inspection and testing documents and materials must be completed promptly and signed and confirmed by relevant inspectors. First, place the casing retainer caps on both ends of the casing, eliminating the need for tape to seal the casing. Then, insert the capped casing into the beam at the predetermined elevation. Secure the casing retainer to the formwork with screws using an electric drill, ensuring a tight fit and quick and easy operation. This process can be completed by general workers without the need for welders or other skilled workers. It also overcomes the previous problem of inaccurate elevation caused by fluctuations in the steel bars during welding.
