A construction engineering house building wall pre-burying construction equipment

Abstract

This invention relates to the field of building construction, and more particularly to a construction device for pre-embedded components in building walls. The device, as described in this invention, features a vertical guide rail on a lifting frame with vertical rods. These rods are first electromagnetically attached to pre-embedded plates already installed in the wall using an electromagnet. The lifting frame then lowers the worker to the lower installation position to install the next set of pre-embedded plates and pre-embedded screws. The lifting frame is not easily affected by crosswinds, thus preventing slight swaying. This invention solves the technical problem of swaying caused by crosswinds when workers are drilling and installing pre-embedded components on walls, which affects the worker's operational accuracy and construction efficiency.

Description

Technical Field

[0001] This invention relates to the field of building construction, and in particular to a pre-embedded construction device for building walls. Background Technology

[0002] In existing building construction projects, when multiple sets of embedded plates and matching embedded screws need to be installed sequentially from top to bottom on the wall, workers usually need to ride a lifting scaffold. An external rope lifting device lowers the workers to different heights to complete drilling, fixing of embedded plates, and installation of embedded screws at each installation point. Lifting scaffolds, as reusable high-altitude work equipment, are widely used in exterior wall construction, curtain wall installation, and insulation work on high-rise buildings. However, the suspension points of lifting scaffolds are usually located at the top of the building, relying on working ropes and safety ropes at both ends or one side to suspend them in the air. The entire lifting scaffold system lacks a rigid track to constrain its translational movement, relying solely on flexible... The steel wire rope maintains basic stability. During the layer-by-layer lowering operation from top to bottom, as the length of the cable increases, the swaying distance of the steel wire rope also increases, leading to an increase in the overall flexibility of the lifting frame. Even though the cable lifting equipment itself has a certain anti-large sway function, when there is crosswind or gust interference in the site environment, the lifting frame will still inevitably produce small amplitude swaying, which will affect the efficiency of construction work and pose safety hazards. When the lifting frame continuously produces small amplitude swaying, the operation accuracy of workers drilling holes in the wall with hand-held drilling machines will be greatly reduced. It is not only difficult to ensure the horizontal spacing and vertical alignment accuracy of multiple pre-embedded screw holes, but it is also easy to cause hole position deviation, waste holes, or even damage to structural steel bars due to deviation. Summary of the Invention

[0003] To overcome the drawback that when workers ride a lifting scaffold to drill holes and install embedded parts on the wall, the scaffold may sway due to crosswinds, affecting the workers' operational accuracy and construction efficiency, this invention provides a wall embedding construction device for building engineering.

[0004] Technical Solution: A pre-embedded construction device for building walls in construction engineering includes a lifting frame, a vertical guide rail, vertical rods, limiting blocks, connecting rods, a control console, a longitudinal slider, an electrically controlled telescopic rod, a pressure plate, and an electromagnet. The lifting frame is fixedly connected to the vertical guide rail. Two vertical rods are slidably connected to the rear side of the vertical guide rail. Limiting blocks are fixedly connected to the vertical rods and closely attached to the vertical guide rail. Several connecting rods are fixedly connected between the two vertical rods. A longitudinal slider is slidably connected to the vertical rod. An electrically controlled telescopic rod is installed on the vertical rod to drive the longitudinal slider to move back and forth. A pressure plate is fixedly connected to the rear side of the longitudinal slider. An electromagnet is installed on the pressure plate. A control console is installed on the vertical guide rail to control the operation of the electrically controlled telescopic rod and the electromagnet.

[0005] Furthermore, it is particularly preferred that the pressure plate is made of insulating rubber material.

[0006] Furthermore, it is particularly preferred that an auxiliary battery is installed on the longitudinal slider to provide auxiliary power to the electromagnet.

[0007] Furthermore, it is particularly preferred that a vertical slide rail is provided on both the left and right sides of the vertical guide rail; a longitudinal slide rail is provided on both the left and right sides of the vertical guide rail, connecting to the vertical slide rail on the same side, and the longitudinal slide rail is located above the vertical slide rail on the same side; a double-axial slider is slidably connected in the vertical slide rail of the vertical guide rail; two left and right locking rod structures are fixedly connected to the double-axial slider, and the distance between the opposite sides of the two locking rods is the same as the distance between two adjacent pre-embedded screws in the same installation position.

[0008] Furthermore, it is particularly preferred that the biaxial slider is fixed to a first permanent magnet.

[0009] Furthermore, it is particularly preferred that the biaxial slider is fixedly connected to a tie rod.

[0010] Furthermore, it is particularly preferred that a height measuring scale for calibrating the borehole height spacing is fixed to the left and right sides of the vertical rod.

[0011] Furthermore, it is particularly preferred that the vertical guide rail has a slot structure; a calibration plate is inserted into the slot of the vertical guide rail.

[0012] Furthermore, it is particularly preferred that the calibration plate has at least two positioning grooves for calibrating the lateral spacing of the drill holes.

[0013] In addition, it is particularly preferred that a second permanent magnet is fixed to the calibration plate; the height measuring ruler is made of stainless steel.

[0014] Beneficial effects: The present invention provides a wall pre-embedded construction equipment for building engineering. The vertical guide rail of the lifting frame is equipped with a vertical rod. First, the vertical rod is electromagnetically attracted and fixed to the pre-embedded plate that has been installed in the wall by an electromagnet. The lifting frame lowers the workers to the lower installation position to carry out the installation and fixing of the next set of pre-embedded plates and pre-embedded screws. The lifting frame is not easily affected by crosswinds and will not sway slightly. It is also equipped with a height measuring ruler and a calibration plate to accurately guide the drilling position of the upper and lower rows of installation holes, ensuring that the spacing of the pre-embedded screw holes remains strictly consistent. This significantly improves the positioning efficiency, hole accuracy and operation convenience of installing multiple sets of pre-embedded parts and matching pre-embedded screws layer by layer.

[0015] The present invention relates to a construction equipment for pre-embedded parts in building construction, which solves the technical problem that when workers ride a lifting frame to drill holes and install and fix pre-embedded parts on the wall, the lifting frame will sway due to crosswinds, which will affect the workers' operating accuracy and construction efficiency.

Detailed Implementation

[0018] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0019] Example 1: This example describes a construction device for pre-embedded wall components in building construction. Figures 1-4As shown, the system includes a lifting frame 1, a vertical guide rail 2, vertical rods 3, limit blocks 31, connecting rods 32, a control console 4, a longitudinal slider 41, an electrically controlled telescopic rod 42, a pressure plate 43, and an electromagnet 44. The vertical guide rail 2 is fixedly connected to the rear side of the lifting frame 1. Two vertical rods 3 are slidably connected to the rear side of the vertical guide rail 2. Each of the two vertical rods 3 has a limit block 31 fixedly connected to it, and the limit blocks 31 are initially in close contact with the surface of the vertical guide rail 2. Several connecting rods 32 are fixedly connected between the two vertical rods 3. Each of the two vertical rods 3 has a longitudinal slider 41 slidably connected to it. Each of the two vertical rods 3 has an electrically controlled telescopic rod 42 installed on it. The telescopic ends of the two electrically controlled telescopic rods 42 are respectively fixedly connected to the longitudinal sliders 41 on the same side. Each of the two longitudinal sliders 41 has a pressure plate 43 fixedly connected to its rear side. Each of the two pressure plates 43 has an electromagnet 44 installed on it. A control console 4 is installed on the vertical guide rail 2 to control the operation of the electrically controlled telescopic rods 42 and the electromagnets 44.

[0020] like Figure 4 As shown, the pressure plate 43 is made of insulating rubber. When the pressure plate 43 presses tightly against the embedded plate under the electromagnetic attraction of the electromagnet 44, a large static friction force will be generated between the insulating rubber pressure plate 43 and the embedded plate in multiple directions, preventing the lifting frame 1 from pulling the pressure plate 43 and the surface of the embedded plate to produce lateral sliding displacement under the influence of crosswinds. Each of the two longitudinal sliders 41 is equipped with an auxiliary battery 45. The electromagnet 44 is electrically connected to the power supply through an external winding cable. During the descent of the electromagnet 44 following the lifting frame 1, the external winding cable continuously releases the cable downwards, which is then supplied by the connected power supply. The power supply provides electricity to the electromagnet 44 to generate electromagnetic attraction. At the same time, the power supply will fully charge the auxiliary battery 45. Since the power supply of the winding cable often experiences voltage drop and power fluctuation due to poor contact of the cable drum, when the power supply is temporarily reduced to the electromagnet 44 due to the influence of the winding cable, the auxiliary battery 45 will promptly replenish the power supply to the electromagnet 44 to ensure that the electromagnetic attraction generated by the electromagnet 44 is continuous and stable. This avoids the loosening or accidental detachment of the adsorption between the electromagnet 44 and the embedded plate due to the attenuation of the electromagnetic attraction of the electromagnet 44, thus ensuring the fixed reliability of the lifting frame 1 in the air.

[0021] Workers install the lifting frame 1 onto the external cable lifting equipment. While riding the lifting frame 1, workers operate the external cable lifting equipment to move the lifting frame 1 from top to bottom to the first installation height on the wall surface. Using a portable drilling machine, they drill four installation holes in two rows on the wall surface, arranged in a matrix. Workers then insert and fix four pre-embedded screws into the four installation holes, simultaneously fixing pre-embedded plates between the four pre-embedded screws and the wall surface. This completes the installation of one set of pre-embedded plates and the matching four pre-embedded screws at the current installation position. After installing and fixing the embedded screws, find the next installation position on the other side of the wall at the same height, and follow the same steps to install and fix the next set of embedded plates and the four matching embedded screws. This will ensure that there is a set of embedded plates and embedded screws installed on each of the left and right sides of the wall at the same height, and that the two embedded plates installed at the same height are aligned vertically with the two pressure plates 43. Then, the staff will use a pull-out tester to perform pull-out tests on the eight installed embedded screws to determine whether the installation of the eight embedded screws is secure.

[0022] After testing the stability of all embedded bolts at the current installation height and confirming they were all satisfactory, the staff prepared to install and fix the next two sets of embedded plates and matching embedded bolts at the installation location below the wall. First, the staff pulled the connecting rod 32, simultaneously raising the two vertical rods 3 along the vertical guide rail 2. The vertical rods 3 then moved the longitudinal slider 41, the electrically controlled telescopic rod 42, the pressure plate 43, and the electromagnet 44 upwards until the pressure plate 43 and the electromagnet 44 were aligned with the embedded plates installed on the same side. The staff then operated the control console 4 to control the electrically controlled telescopic rod 42 to pull the longitudinal slider 41, causing the pressure plate 43 and the electromagnet 44 to press backwards onto the embedded plate. The staff also controlled the electromagnet 44 to generate an electromagnetic attraction between itself and the embedded plate, allowing the vertical rod 3 to be firmly fixed to the wall through the electromagnetic attraction between the electromagnet 44 and the embedded plate. Afterwards, the staff operated the external cable lifting equipment to control the lifting frame 1 to move downwards to the next installation height on the wall surface. The lifting frame 1 moves the vertical guide rail 2 downwards along the vertical rod 3. After the worker controls the external cable lifting equipment to stop moving, they can complete the installation and fixing of the left and right sets of embedded plates and matching embedded screws at the current installation height on the wall according to the above steps. During this period, even if the lifting frame 1 is blown by crosswinds and generates oblique tension on the vertical rod 3, the vertical rod 3 will distribute the oblique tension to each embedded screw and the wall through the embedded plates. The tension distributed to each embedded screw is much smaller than the oblique tension on the vertical rod 3. Therefore, it can be ensured that the vertical rod 3 can resist the oblique tension generated by the crosswind and keep the lifting frame 1 stationary. This allows the worker to stably install and fix the embedded plates and matching embedded screws on the lifting frame 1, greatly improving the worker's operating accuracy and construction efficiency.

[0023] Example 2, based on Example 1, such as Figures 1-7 As shown, a vertical slide rail 201 is provided on both the left and right sides of the vertical guide rail 2; a longitudinal slide rail 202 is provided on both the left and right sides of the vertical guide rail 2, connecting the vertical slide rail 201 on the same side, and the longitudinal slide rail 202 is located above the vertical slide rail 201 on the same side; a dual-axis slider 5 is slidably connected to each of the two vertical slide rails 201 of the vertical guide rail 2. The dual-axis slider 5 can slide along the vertical slide rail 201 and the longitudinal slide rail 202 respectively. The dual-axis slider 5 is initially located in the vertical slide rail 201, and the dual-axis slider 5 can slide along the vertical slide rail 201. 201 moves up and down. When the biaxial slider 5 moves upward along the vertical slide 201 to align with the longitudinal slide 202, the biaxial slider 5 can move forward and backward along the longitudinal slide 202. Each of the two biaxial sliders 5 is fixedly connected to two left and right locking rods 51, and the distance between the opposite sides of the two locking rods 51 is the same as the distance between two adjacent pre-embedded screws in the same installation position. Each of the two biaxial sliders 5 has a first permanent magnet 52 fixedly connected to its rear side. Each of the two biaxial sliders 5 has a pull rod 53 fixedly connected to its front side.

[0024] During the installation and fixing of two sets of embedded plates and matching embedded screws at the same installation height on the wall, the upper end of the vertical rod 3 is electromagnetically attracted and fixed to another embedded plate above by the electromagnet 44, so that the lifting bracket 1 is fixed at the current height position by the vertical rod 3. After the installation and fixing of the two sets of embedded plates and matching embedded screws at the current installation height is completed, and the embedded screws pass the pull test using a pull tester, if there is a crosswind, before the operator controls the control panel 4 to disconnect the electromagnetic attraction between the electromagnet 44 and the upper embedded plate, the operator first pulls the pull rod 53 to move the biaxial slider 5 upward along the vertical slide 201 to align with the longitudinal slide 202, and then pushes the pull rod 53 to move the biaxial slider 5. Moving backward along the longitudinal slide rail 202, the two locking rods 51 on the biaxial slider 5 are locked backward between the four pre-embedded screws installed at the same height on the wall, and the first permanent magnet 52 on the rear side of the biaxial slider 5 is magnetically fixed to the pre-embedded plate. This allows the lifting frame 1 to be temporarily fixed to the wall by the locking rods 51 and the first permanent magnet 52 on the two biaxial sliders 5 on the vertical guide rail 2. Afterward, the operator controls the control console 4 to disconnect the electromagnetic attraction between the electromagnet 44 and the pre-embedded plate above, which can then pull the vertical rod 3 to move downward along the vertical guide rail 2. During this process, the locking rods 51 and the first permanent magnet 52 on the biaxial slider 5 will replace the electromagnet 44 on the vertical rod 3 to temporarily fix the lifting frame 1, forming a continuous resistance to crosswinds.

[0025] Example 3, based on Example 1, such as Figures 1-5 and Figure 8As shown, a height measuring scale 33 is fixedly connected to the left and right sides of the vertical rod 3; a slot 203 structure is opened on the left and right sides of the vertical guide rail 2; a calibration plate 6 is inserted into each of the two slots 203 of the vertical guide rail 2; two positioning grooves 601 structures are opened on each of the two calibration plates 6; a second permanent magnet 61 is fixedly connected to the rear side of each of the two calibration plates 6; the height measuring scale 33 is made of stainless steel.

[0026] After completing the installation and fixing of the two sets of embedded plates and matching embedded screws at the same installation height on the wall, and after the embedded screws pass the pull-out test using a pull-out tester, the workers follow the above steps to electromagnetically fix the vertical rod 3 to the embedded plate using the electromagnet 44. Then, they operate the external cable lifting device to control the lifting frame 1 to move the vertical guide rail 2 downwards along the vertical rod 3. Simultaneously, the vertical guide rail 2 continuously moves downwards past each scale position of the height measuring scale 33 until it aligns with the designated scale position on the height measuring scale 33. The workers then control the external cable lifting device to stop moving, thus accurately lowering the lifting frame 1 to the designated height position. At this point, the workers are directly lowered to the next installation position on the wall without repeatedly confirming the correct height position of the lifting frame 1. Afterwards, the workers pull the calibration plate 6 out of the slot 203 and magnetically attach it to the designated scale position on the height measuring scale 33 using the second permanent magnet 61. The two positioning slots 601 on the calibration plate 6 are aligned with the two pre-embedded screws on the upper side of the pre-embedded plate that has been installed above. The lateral spacing between the two positioning slots 601 is also the same as the lateral spacing between the two pre-embedded screws. Then, the worker only needs to use a hand drill to drill the installation holes on the wall at the positions of the two positioning slots 601 respectively, completing the drilling of the two upper installation holes at this installation position. After that, the worker moves the calibration plate 6 down along the height measuring scale 33 to the designated scale position, completing the adjustment of the spacing between the positioning slots 601 and the installation holes just drilled on the upper side. Then, the worker uses a hand drill to drill the installation holes on the wall at the positions of the two positioning slots 601 respectively, completing the drilling of the two lower installation holes at this installation position. After that, the worker removes the calibration plate 6 from the height measuring scale 33 and inserts it back into the slot 203. The pre-embedded plate and the four matching pre-embedded screws can then be installed and fixed between the four installation holes drilled at this installation position.

[0027] Afterwards, the staff used the calibration plate 6 on the other side to install and fix another set of embedded plates and embedded screws at the same installation height on the wall. This solution uses the height measuring ruler 33 to achieve one-time accurate lowering of the lifting bracket 1, and with the calibration plate 6, accurately guides the drilling position of the upper and lower rows of installation holes, ensuring that the spacing of the embedded screw holes remains strictly consistent, which significantly improves the positioning efficiency, hole accuracy and operation convenience of installing multiple sets of embedded parts and matching embedded screws layer by layer.
