Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment technology for building construction, specifically a vertical correction device for the construction of exposed brick walls in ancient buildings. Background Technology

[0002] Because exposed brick walls require no additional plastering or decoration, the masonry surface serves as the decorative surface, demanding extremely high verticality in masonry construction. Current methods for checking verticality during exposed brick wall construction often rely on simple tools like plumb lines and straightedges, resulting in low accuracy and delayed correction. When verticality deviations are detected, traditional correction methods often involve manually prying the wall, which is not only cumbersome and inefficient but also prone to loosening masonry blocks and mortar falling off, damaging the surface smoothness and affecting construction quality and aesthetics. Furthermore, existing correction devices primarily address the overall correction of completed walls, failing to meet the real-time dynamic correction needs during construction, thus lacking versatility and practicality. Therefore, this invention proposes a vertical correction device for exposed brick wall construction in ancient architecture. Summary of the Invention

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. Example 1:

[0017] This invention provides a vertical correction device for the construction of exposed brick walls in ancient buildings. Please refer to [link / reference]. Figures 1-5 It includes a vertically arranged reference frame 10, which is made of aluminum alloy, making it lightweight and strong. One side of the reference frame 10 is a positioning surface that fits against the exposed concrete wall, and the positioning surface is provided with an anti-slip rubber pad 11, which increases the friction with the wall and avoids scratches caused by direct contact between the reference frame and the wall.

[0018] The reference frame 10 is equipped with adjustment components on both the left and right sides for pushing and correcting the wall. The adjustment assembly includes: a support base 20, an adjustment screw 21, a push plate 22, a flexible buffer pad 23, an adjustment handle 24, and a guide rod 25; The reference frame 10 has support seats 20 fixedly installed on both sides by screws; the adjusting screw 21 is threadedly connected to the support seat 20; one end of the adjusting screw 21 is rotatably connected to the push plate 22 through a bearing, ensuring that the push plate 22 only moves horizontally when the adjusting screw 21 rotates, and the push plate 22 is made of steel plate; the flexible buffer pad 23 is provided on the outer side of the push plate 22, and the flexible buffer pad 23 is made of polyurethane to avoid damage to the fair-faced wall surface during the push process; the adjusting handle 24 is fixedly installed on the other end of the adjusting screw 21, and the surface of the adjusting handle 24 is provided with an anti-slip sleeve to facilitate the operator to apply force to rotate; the guide rod 25 is fixedly installed on the inner side of the push plate 22, and the guide rod 25 is slidably connected to the support seat 20.

[0019] The top of the reference frame 10 is equipped with a detection component for measuring the verticality deviation of the wall. The detection components include: a spirit level 36 and a feeler gauge 37; The level 36 is mounted on the top of the reference frame 10 via a bracket; the feeler gauge 37 is inserted into the gap between the level 36 and the wall.

[0020] The bracket includes: a support plate 30, a hollow square tube 31, a square rod 32, a hand-tightening screw 33, a threaded groove 34, and a damping spring 35; The support plate 30 is fixedly installed on the top of the reference frame 10 by screws; hollow square tubes 31 are fixedly installed on both the upper and lower sides of the support plate 30; the square rod 32 is slidably connected in the hollow square tube 31, and one end of the square rod 32 is fixedly installed with a level 36 by bolts. The measuring reference surface of the level 36 is vertical and parallel to the positioning surface of the reference frame 10, which can form a clear vertical reference line; the damping spring 35 is sleeved on the square rod 32, and both ends of the damping spring 35 are fixedly connected to the hollow square tube 31 and the level 36 respectively; a hand-tightening screw is threaded to the top of one end of the hollow square tube 31. 33; The top of the square rod 32 is provided with a threaded groove 34, and one end of the hand-tightening screw 33 is threaded into the threaded groove 34; A spirit level is embedded in the front of the reference frame 10 to calibrate the verticality of the reference frame itself and ensure the accuracy of the horizontal ruler reference line. At the same time, a scale line is engraved vertically on the front of the reference frame 10. The scale line has a graduation value of 1mm and is parallel to the vertical reference line of the horizontal ruler 36. When used with a feeler gauge 37, the gap between the wall and the horizontal ruler reference surface can be measured by the feeler gauge. The deviation distance between the wall and the reference line can be read intuitively by combining the scale line, so as to realize the quantitative detection of the deviation. Specifically, before using the detection assembly, the hand screw 33 is threaded into the threaded groove 34, which allows the hollow square tube 31 and square rod 32 to be retracted to reduce space occupation. At this time, the damping spring 35 is in a compressed state. When using the detection assembly, the hand screw 33 and the threaded groove 34 are first separated. At this time, the level 36 will move towards the wall under the action of the damping spring 35.

[0021] The bottom of the reference frame 10 is provided with a positioning component for positioning the reference frame 10.

[0022] The positioning components include: a vacuum adsorption seat 40, a flow channel 41, a vacuum suction cup 42, a vacuum pump 43, and a pipe 44; The vacuum adsorption seat 40 is fixedly mounted on the bottom of the reference frame 10 by screws; the flow channel 41 is formed in the vacuum adsorption seat 40; several vacuum suction cups 42 are fixedly mounted on the bottom end of the vacuum adsorption seat 40 and are connected to the flow channel 41; the vacuum pump 43 is fixedly mounted on the top of the vacuum adsorption seat 40; the pipe 44 is fixedly mounted on the air inlet end of the vacuum pump 43, and one end of the pipe 44 is fixedly mounted on the top end of the vacuum adsorption seat 40 and is connected to the flow channel 41. Through the cooperation of the vacuum pump 43 and the vacuum suction cups 42, the reference frame 10 can be positioned on the completed concrete blocks or bricks by negative pressure adsorption; at the same time, the position of the vacuum adsorption seat 40 can be fixed by screws. Example 2:

[0023] This invention provides a vertical correction device for the construction of exposed brick walls in ancient buildings. Please refer to [link / reference]. Figure 6The positioning component includes: a magnetic adsorption seat 50; The magnetic adsorption seat 50 is fixedly installed on the bottom of the reference frame 10 by screws so that it can be adsorbed onto the block of magnetic adsorption material. Based on this, it can be quickly adsorbed onto the completed concrete block or brick. At the same time, the position of the magnetic adsorption seat 50 can be fixed by screws.

[0024] In use, first, attach the positioning surface of the reference frame 10 to the completed exposed concrete wall surface, and initially fix the device using the positioning components. Observe the vertical level bubble and adjust the verticality of the reference frame 10 to ensure that the vertical level bubble is centered. The operator uses the vertical reference line of the level 36 to align with the area to be built and lays the blocks according to the reference line. When a verticality deviation of the wall is suspected, insert a feeler gauge 37 into the gap between the wall and the vertical reference surface of the level 36, read the measurement value of the feeler gauge, and confirm the deviation range and position by referring to the scale lines on the reference frame 10. Rotate the adjusting handle 24 on the corresponding side according to the direction of deviation, drive the adjusting screw 21 to push the push plate 22 to push the wall. During the process, continuously check the gap with the feeler gauge 37 until the gap is zero (the wall is aligned with the level reference line). After completing the correction, continue laying the blocks.

[0025] Based on the above, the specific operating steps for those skilled in the art are as follows: Step 1: Preliminary preparation and benchmark calibration 1.1 Material and Equipment Preparation: Select new bricks (with consistent material, size, and color) that match the original brick materials of the ancient building (such as blue bricks and stone bricks), and traditional mortar (such as lime-hemp mortar and glutinous rice mortar); the core equipment selected is a vertical correction device for fair-faced brick masonry adapted to the ancient building scene; at the same time, in view of the characteristics of weathered brick materials of ancient buildings, prepare additional 3-5mm thick hard plastic support plates (to meet the stress buffering requirements of the device's adjustment mechanism) and ≤1mm thick flexible silicone pads (to meet the leveling requirements of the device's benchmark positioning). 1.2 Benchmark Calibration (corresponding to the positioning function of the benchmark frame of the device): On the outside of the completed benchmark wall section (height ≥ 50cm), first clean the dust on the brick surface. If the wall surface is uneven, insert a flexible silicone pad (thickness ≤ 1mm) between the level and the wall surface to ensure the straightness of the vertical benchmark surface of the level. After observing that the bubble of the level is centered, lock the position. Using the vertical edge of the level as the benchmark, use the ink line to pop out continuous vertical benchmark lines. The benchmark lines should be 5-8mm away from the wall plaster layer (if present) or the edge of the brick surface to avoid obstructing the masonry operation space. At the same time, ensure that the benchmark lines are clearly visible and do not damage the original wall. This completes the methodological implementation of the benchmark function of the device. Step 2: Real-time verticality detection during the masonry process 2.1 Layered masonry and initial inspection: Lay mortar and bricks in layers according to the traditional masonry process of ancient buildings. After each layer of bricks is laid, pause the mortar laying and place a vertical level against the outside of the current masonry layer to ensure that the bubble on the level is centered. 2.2 Deviation Quantification Detection: Insert a feeler gauge into the gap between the vertical reference surface of the level and the brick surface, and check 3 evenly distributed test points (spaced 20-30cm apart) from bottom to top, recording the deviation value of each test point; follow the principle of "maximum gap reading of feeler gauge" during the test to ensure accurate deviation quantification; if the deviation value is ≤0.5mm, it meets the accuracy requirements for the construction of ancient building exposed brick walls, and proceed to the next layer of construction; if the deviation value is >0.5mm, perform the correction operation in step 3; Step 3: Non-destructive and precise deviation correction operation 3.1 Correction and Positioning: Based on the deviation value and direction (inward or outward tilt) recorded in step 2, precise positioning is achieved using the adjustment and positioning components of the device; a flexible buffer pad is attached to the outside of the brick corresponding to the detection point of maximum deviation. If the brick is severely weathered, a rigid plastic support plate is added to the outside of the buffer pad (to increase the bearing area and match the device's protective design for fragile bricks); the pushing end of the device is aligned with the center of the buffer pad and fixed to the completed benchmark wall section through the positioning components, ensuring that the pushing direction is perpendicular to the wall surface to avoid force deviation and damage to the wall; 3.2 Graded Force Application and Correction: Utilizing the precision transmission characteristics of the adjusting screw, a "graded force application and real-time monitoring" method is adopted. The adjusting handle is rotated, pausing after every 1 / 4 turn (corresponding to a jacking displacement of approximately 0.2mm, matching the transmission accuracy of the device). A feeler gauge is used to detect the deviation value at the corresponding detection point in real time. The force amplitude is adjusted according to the deviation value. When the deviation value is >2mm, the single jacking displacement does not exceed 0.3mm; when the deviation value is ≤2mm, the single jacking displacement does not exceed 0.1mm, until the deviation value at each detection point is ≤0.5mm, thus achieving a refined method for the device's adjustment function. 3.3 Fixing after correction: After correction, maintain the state for 3-5 minutes to ensure that the brick and mortar are fully and stably bonded; if mortar is squeezed out, gently clean the excess mortar with a soft brush, and do not pry the brick; then remove the adjustment components and use a blower to clean the residual mortar on the brick surface.

[0026] Step 4: Re-inspection and Acceptance 4.1 Layered re-inspection: After the correction is completed, use a vertical level and feeler gauge to re-check the verticality of each test point. At the same time, check whether there is any damage to the brick surface or whether the mortar joints are loose. If there are any problems, repeat steps 3-4.1. 4.2 Overall Acceptance: After every 3-5 layers of masonry, a 2m straightedge and feeler gauge are used to check the overall verticality to ensure that the overall deviation is ≤2mm / 2m, which meets the accuracy requirements for the repair of exposed brick walls in ancient buildings in the "Technical Specification for Building Repair Engineering" (DG / TJ08-207-2008).
