Description
Technical Field
[0001] This invention relates to the field of building construction technology, specifically to a novel construction method for cast-in-place irregular beam structures. Background Technology
[0002] As the name suggests, irregular beam structures are beams with irregular cross-sections, unlike the rectangular shapes of ordinary frame structures. Because of the irregular cross-section, wooden formwork is used during the pouring process, which is difficult to bend. This leads to errors in the design of the irregular beam structure during installation, thus reducing its stability.
[0003] To address the aforementioned problems, Chinese Patent Publication No. CN116517274A discloses a novel construction method for cast-in-place irregular beam structures, comprising the following steps: Step 1, segmentation; Step 2, cutting; Step 3, laying; Step 4, support; Step 5, fixing; Step 6, casting. In Step 1, the irregular beam is segmented according to its length. In Step 2, the casting templates required for each segment of the irregular beam are cut to obtain templates of the desired shape, and then the cut casting templates are spliced onto the outer surface of the irregular beam. In Step 3, the partial casting templates required for each segment of the irregular beam are laid sequentially according to the shape of the irregular beam. This invention, by segmenting the irregular beam and using casting templates to lay each segment, utilizes multiple spliced casting templates to assemble the required irregular beam structure, reducing the error of the irregular beam structure and thus improving its stability.
[0004] In actual use, the aforementioned patent involves segmenting the irregular beams according to their length. This segmentation is primarily accomplished through a cutting process. However, traditional cutting equipment can only cut individual beams. When cutting a batch of beams, the efficiency of traditional cutting equipment is low, severely impacting the construction progress. Summary of the Invention
[0005] The present invention aims to provide a novel construction method for cast-in-place irregular beam structures to solve the problem of low work efficiency in the segmented processing method of existing construction methods.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a novel construction method for cast-in-place irregular beam structures, comprising the following steps:
[0007] Step 1, Segmentation; Several irregular beams are segmented one by one, which requires the use of a cutting device; The cutting device includes a base and a cutting mechanism. The base has limiting parts on both sides along the width direction of the base. The limiting parts include a fixed shaft fixed to the base and a sliding groove opened on the base. Limiting blocks are rotatably connected to both sides of the fixed shaft. A torsion spring is provided between the limiting blocks and the fixed shaft. The two limiting blocks are set in a V shape. A slider that abuts against the limiting block is slidably connected in the sliding groove. The cutting device also includes an adjustment mechanism for adjusting the distance between the two sliders.
[0008] Several beams are placed on the base, so that the beams are positioned between two limiting parts; the distance between the two sliders is reduced by the adjustment mechanism, and the sliders simultaneously squeeze the two limiting blocks on a single fixed shaft to rotate, so that the included angle between the two limiting blocks on the single fixed shaft increases and the torsion spring deforms; the limiting blocks on both sides of the base clamp the beams; and then the beams are cut by the cutting mechanism to obtain several beam segments of the required size.
[0009] Step 2, Shaping; Cut the required casting template for the outer surface of each beam segment to obtain the template of the required shape, and then splice the cut casting template onto the outer surface of the irregular beam.
[0010] Step 3, Laying: Lay the formwork for each irregular beam according to its shape, and seal the gaps between the formwork with sealing strips. During the laying process, use limiting rods for ring fixation, and then use support rods to fix the limiting rods, thereby supporting the limiting rods and the formwork.
[0011] Step 4, Support; During the support process using the support rod, a horizontal plate is installed at the bottom of the support rod;
[0012] Step 5, Fixing; If there are other objects blocking the support rod below during the support process, and the support rod cannot be used for support, the crossbar can be fixed on the limit rod, and then the support rod can be used to fix the crossbar.
[0013] Step 6, pouring: Pour the required type of cement into the beam formwork. During the pouring process, use a cement vibrator to vibrate the cement and use the formwork to level the pouring opening. After standing for a period of time, remove the support rods and then remove the limiting rods from the beam formwork to complete the pouring work.
[0014] Furthermore, in step two, the base is provided with a groove, and the fixing shaft is located in the groove; several beams are placed in the groove so that the clamping and cutting of the beams are all done in the groove.
[0015] Furthermore, in step two, the adjustment mechanism includes a chamber inside the base, a bidirectional screw rotatably connected to the base, and a drive unit for driving the bidirectional screw to rotate. The bidirectional screw passes through the chamber; the chamber communicates with the slide groove, and the slider is threadedly connected to the bidirectional screw; the drive unit drives the bidirectional screw to rotate, thereby reducing the distance between the two sliders.
[0016] Furthermore, in step one, the base is provided with pressing parts on both sides along its length. The pressing part includes a vertical plate and a guide cylinder connected to the vertical plate. A pressing block is slidably connected inside the guide cylinder. A first spring is provided between the pressing block and the inside of the guide cylinder. The pressing block is provided with a stop groove. The guide cylinder is provided with a vertical groove communicating with the inside of the guide cylinder. A stop block is slidably connected inside the vertical groove. A second spring is provided between the stop block and the outer wall of the guide cylinder. The vertical groove communicates with the stop groove. The stop block extends into the stop groove and can move within the stop groove. The pressing part also includes a linkage unit that drives the stop block to move vertically as the limiting block moves. After the beam is placed in the groove, the top of the beam is below the pressing block. During the rotation of the limiting block, the limiting block drives the stop block to move vertically through the linkage unit. After the stop block moves out of the stop groove, the second spring is stretched. Under the action of the first spring, the pressing block moves away from the guide cylinder, so that the bottom of the pressing block abuts against the top of the beam, thereby pressing several beams.
[0017] Furthermore, the linkage unit includes a top groove on the base, a horizontal groove on the base, a round shaft rotatably connected to the upright plate, and a side groove vertically on the upright plate. A top block is slidably connected in the top groove, and a third spring is provided between the top block and the top groove. The end of the limiting block away from the fixed shaft is hinged to the top block. A rack is slidably connected in the horizontal groove and is fixedly connected to the top block. A gear and a cam are coaxially connected on the round shaft, and the gear meshes with the rack. A lifting block is slidably connected in the side groove, and the lifting block is fixedly connected to the stop block. The cam abuts against the lifting block. During the rotation of the limiting block, the limiting block drives the top block to move in the top groove, and the third spring is stretched. The top block drives the rack to move synchronously, and the rack meshes with the gear to drive the gear to rotate. The gear drives the cam to rotate through the round shaft, so that the protrusion of the cam squeezes the lifting block to move vertically. The lifting block drives the stop block to move synchronously, so that the stop block moves out of the stop groove.
[0018] Furthermore, the upright plate is provided with a strip groove, the guide cylinder is slidably connected to the strip groove, and a fifth spring is provided between the guide cylinder and the upright plate; it also includes an active part that drives the guide cylinder to move with the movement of the top block; after the pressure block moves away from the guide cylinder, the top block drives the guide cylinder to move along the path of the strip groove through the active part, the fifth spring is compressed, which reduces the distance between the two guide cylinders, and then makes the free ends of the two pressure blocks abut against each other.
[0019] Furthermore, the moving part includes motion units arranged on both sides of the base along the length of the base. The motion unit includes a first wedge fixedly connected to the top block and a guide groove formed on the upright plate. A second wedge for being squeezed by the first wedge is slidably connected in the guide groove. A sixth spring is provided between the second wedge and the upright plate. The second wedge is located on the movement trajectory of the first wedge and is fixedly connected to the guide cylinder. During the movement of the top block, the top block drives the first wedge to move, so that the first wedge squeezes the second wedge to move along the path of the guide groove, that is, the distance between the two second wedges decreases. The second wedge drives the guide cylinder to move along the path of the strip groove.
[0020] Further, in step one, the cutting mechanism includes side plates fixed to both sides of the base along the width direction of the base, with a top plate between the two side plates; a first cylinder is provided at the bottom of the top plate, and a moving block is fixedly connected to the output shaft of the first cylinder, the moving block being slidably connected to the bottom of the top plate, and the moving block moving along the width direction of the base; cutting sections are provided on both sides of the bottom of the moving block along the width direction of the moving block, each cutting section including a power motor and a second cylinder fixedly connected to the bottom of the moving block, a first auxiliary block being fixedly connected to the output shaft of the second cylinder, the first auxiliary block being slidably connected to the bottom of the moving block; a third cylinder is provided at the bottom of the first auxiliary block, the third... A second auxiliary block is fixedly connected to the output shaft of the cylinder, and the movement direction of the second auxiliary block is perpendicular to the movement direction of the first auxiliary block. A power motor is fixedly connected to the second auxiliary block, and a cutting blade is coaxially connected to the output shaft of the power motor. After clamping and pressing several beams, the positions of the two first auxiliary blocks are adjusted by the second cylinders on both sides of the moving block according to the cutting requirements, thereby adjusting the positions of the two cutting blades. The height of the cutting blade is then adjusted by the second cylinder, and the output shaft of the power motor drives the cutting blade to rotate. Finally, the first cylinder drives the moving block to move along the width direction of the base, thereby driving the cutting blade to cut the beams.
[0021] The principle and advantages of this scheme are:
[0022] 1. This solution divides the irregular beam into segments and uses casting templates to lay each segment. By using multiple spliced casting templates to form the required irregular beam structure, the error of the irregular beam structure is reduced, thereby improving the stability of the irregular beam structure. At the same time, laying each segment makes it easier to cut the casting template according to the different structures of each segment, and also facilitates the division of labor and improves the casting efficiency.
[0023] 2. This solution can cut two or more irregular beams simultaneously in a single operation, allowing multiple beam segments to be obtained in a single cut, thus enabling batch processing, effectively improving work efficiency and ensuring construction progress.
[0024] 3. This solution mainly uses the limiting blocks on both sides of the base to clamp the irregular beam. The two limiting blocks on one side of the base are V-shaped. By changing the included angle of the two limiting blocks on one side of the base to make them abut against the irregular beam, it is possible to clamp irregular beams of different sizes within a certain width range.
[0025] 4. In the initial state of this solution, the position of the pressure block is limited by the stop block, allowing the operator to directly and conveniently place the irregular beam into the groove without being obstructed by the pressure block. When the angle between the two limit blocks on one side of the base is changed, the limit block rotates, which drives the top block and rack to move synchronously. The rack meshes with the gear, which drives the gear to rotate. The gear drives the cam to rotate through the round shaft, causing the cam's protrusion to squeeze the lifting block to move vertically. The lifting block drives the stop block to move synchronously, thus eliminating the limiting effect of the stop block on the pressure block and allowing the pressure block to pop out of the guide cylinder. By using the pressure block to press multiple irregular beams, combined with the clamping of the irregular beams, the positioning effect of the irregular beams can be enhanced, making the cutting of irregular beams more stable.
[0026] 5. After the pressure block moves away from the guide cylinder, the top block drives the first wedge block to move, causing the first wedge block to press the second wedge block along the path of the guide groove, that is, the distance between the two second wedge blocks decreases; the second wedge block drives the guide cylinder to move along the path of the strip groove, which reduces the distance between the two guide cylinders, and then the free ends of the two pressure blocks abut against each other, so as to press all the beams tightly, enhance the positioning effect of irregular beams, and make the cutting of irregular beams more stable.

[0046] Step 4, Support; During the support process, a horizontal plate is set at the bottom of the support rod; at the same time, the top surface of the horizontal plate is parallel to the horizontal plane, and the bottom of the support rod is fixedly connected to the top surface of the horizontal plate, while the bottom plane of the support rod is parallel to the top surface of the horizontal plate.
[0047] Step 5, Fixing; During the support process, if there are other objects blocking the support rod below, making it impossible to use the support rod for support, the cantilever rod can be fixed on the limit rod, and then the support rod can be used to fix the cantilever rod; When encountering an irregular beam that is a horizontal beam, and the angle between the horizontal beam and the horizontal plane is 0-15° or parallel to the horizontal plane, the pouring gate needs to be quantitatively increased on the pouring beam formwork laid on the outer surface of the horizontal beam;
[0048] Step 6, pouring: Pour the required type of cement into the beam formwork. During the pouring process, use a cement vibrator to vibrate the cement and use the formwork to level the pouring opening.
