Description

Technical Field

[0001] This invention relates to the field of culvert construction technology, and in particular to a movable steel formwork assembly structure and pouring method for concrete pouring of wall panels. Background Technology

[0002] Currently, culverts have strong flood discharge capabilities in highway engineering and can also cross roads as passageways for people or vehicles. Culverts typically consist of a cover slab, abutment, culvert platform, foundation, and expansion joints. The cover slab is generally a precast component, while the abutment and foundation need to be cast on-site, often in sections. The traditional construction steps for culvert wall casting are: using a crane to place the side formwork in the predetermined position, which is then installed and fixed by construction workers, followed by the installation of the end formwork. After casting is completed and reaches a certain strength, the formwork is removed, and then the next section of wall formwork is installed. This formwork relocation requires a large amount of manpower and resources. If large tools cannot be used for manual formwork relocation, construction efficiency will be low, damaging the already cast wall and hindering precise control. The traditional formwork installation process is cumbersome, involving high-altitude work for each section, and defects in construction or formwork can lead to common quality problems such as misaligned walls and uneven surfaces. When setting up the formwork for the culvert abutment, the sections of the wall are misaligned; the formwork is repeatedly removed and reused; the construction site is small, making manual formwork movement difficult; there are many high-altitude operations, resulting in a high construction risk factor. Summary of the Invention

[0003] This invention provides a movable steel formwork assembly structure and casting method for concrete pouring of walls to solve the technical problems existing in the prior art.

[0004] The technical solution adopted by this invention to solve the technical problems existing in the prior art is as follows:

[0005] A movable steel formwork assembly structure for concrete pouring of walls includes a fixed formwork, a movable formwork, and guide rails. The fixed formwork and guide rails are fixed to a concrete foundation. The movable formwork includes a vertical formwork and a horizontal plate fixedly connected to each other. The pouring surfaces of the vertical formwork and the fixed formwork face each other. A roller frame is provided on the side of the vertical formwork facing away from the pouring surface. A first roller that rolls with the guide rail is installed on the roller frame, and the first roller is movably connected to the roller frame. The bottom surface of the horizontal plate of the movable formwork has several grooves, and a second roller is rolled within each groove. During concrete pouring, the horizontal plate of the movable formwork is fixed to the concrete foundation by detachable fasteners. Concrete is poured between the movable formwork and the fixed formwork. After the concrete pouring is completed, the horizontal plate of the movable formwork is separated from the detachable fasteners. The first roller is rolled with the guide rail. Under the action of external force, the first roller rolls along the guide rail, and the second roller rolls along the direction of the guide rail on the concrete foundation, thereby moving the movable formwork along the guide rail.

[0006] Furthermore, it also includes calipers, which are evenly provided with several slots; the movable template and the fixed template are provided with several locking blocks that cooperate with the slots on their top surfaces and front and rear sides that are perpendicular to the pouring surface; several calipers are locked onto the locking blocks of the two templates to make the pouring surfaces of the two templates parallel and maintain a set gap.

[0007] Furthermore, the movable template and the fixed template both have protrusions on the top of the locking blocks that restrict the upward movement of the calipers; and the front of the locking blocks on the sides of both have protrusions that restrict the horizontal outward movement of the calipers.

[0008] Furthermore, it also includes several tie bolts; the movable template and the fixed template are provided with several through holes A; the tie bolts pass through the through holes A of the movable template and the fixed template and are fastened.

[0009] Furthermore, the first roller is hinged to the roller frame, or connected to it in a relative lifting or detachable manner.

[0010] Furthermore, a traction ring is provided on the top surface of the fixed template, and a fixed pulley corresponding to the traction ring is provided on the top surface of the movable template. One end of the traction rope is connected to the traction ring, and the other end of the traction rope is connected to an external traction device around the fixed pulley. Under the drive of the traction device, the movable template moves toward the fixed template.

[0011] This invention also provides a method for pouring movable wall concrete. The method includes a fixed template, a movable template, and guide rails. The fixed template and guide rails are fixed to a concrete foundation. The movable template includes a vertical template and a horizontal plate fixedly connected to each other. The pouring surfaces of the vertical template and the fixed template face each other. A roller frame is provided on the side of the vertical template facing away from the pouring surface. A first roller that rolls with the guide rail is installed on the roller frame, and the first roller is movably connected to the roller frame. Several grooves are provided on the bottom surface of the horizontal plate of the movable template, and a second roller is rolled within each groove. During concrete pouring, the horizontal plate of the movable template is fixed to the concrete foundation by detachable fasteners. Concrete is poured between the movable template and the fixed template. After the concrete pouring is completed, the horizontal plate of the movable template is separated from the detachable fasteners, allowing the first roller to roll with the guide rail. Under external force, the first roller rolls along the guide rail, and the second roller rolls along the guide rail on the concrete foundation, thereby moving the movable template along the guide rail.

[0012] Furthermore, a traction ring is installed on the top surface of the fixed template, and a fixed pulley corresponding to the traction ring is installed on the top surface of the movable template; calipers are installed with several slots evenly distributed on them; for both the movable and fixed templates, several locking blocks that mate with the slots are installed on their top and front and rear sides perpendicular to the pouring surface; this method includes the following steps:

[0013] Step 1: Fix the fixed template and track to the concrete foundation, and place the movable template on the concrete foundation, opposite to the first fixed template section;

[0014] Step 2: Connect one end of the traction rope to the traction ring, and connect the other end of the traction rope to the external traction device by winding around the fixed pulley. Driven by the traction device, move the moving template toward the fixed template to adjust the gap between the pouring surfaces of the moving template and the fixed template.

[0015] Step 3: From bottom to top, attach several calipers to the clamps of the moving template and the fixed template to make the pouring surfaces of the moving template and the fixed template parallel and maintain the set gap.

[0016] Step 4: Pour concrete between the movable formwork and the fixed formwork;

[0017] Step 5: After the concrete pouring is completed, remove the detachable fixing parts on the horizontal plate of the movable formwork, so that the first roller rolls into contact with the guide rail, move the movable formwork to the position opposite to the next fixed formwork section, and then disengage the first roller from the guide rail.

[0018] Step 6: Repeat steps 2 to 5 until one side of the wall is poured.

[0019] Furthermore, several tie bolts are also provided; the vertical template and the fixed template of the movable template are provided with several through holes A; in step 3, after the caliper and the clamping block are engaged, the tie bolts are passed through the through holes A of the vertical template and the fixed template of the movable template and tightened.

[0020] Furthermore, an organic board resistant to release oil is also provided; in step 4, before pouring concrete between the moving formwork and the fixed formwork, organic boards are attached to the pouring surfaces of both the moving formwork and the fixed formwork, and release oil is evenly applied to the organic boards.

[0021] The advantages and positive effects of this invention are: 1. Fast disassembly and flexible installation; 2. Simple and flexible operation and fast moving speed; 3. Saving manpower and resources: fixed templates can be installed in advance during formwork erection, eliminating the need for hoisting during formwork movement, reducing high-altitude operations; when large machinery cannot enter the site, movable templates can be used at both ends, and expansion bolts can be used to fix them to the predetermined position; 4. Reducing the construction period and ensuring continuous construction: the use of guide rails and calipers reduces errors and avoids misalignment of each wall section; 5. When controlling the distance between the fixed and movable templates, a traction rope is used through the top traction ring and fixed pulley to control the distance between the fixed and movable templates. Construction personnel can pull from a safe position, while another person only needs to install calipers of the designed dimensions from bottom to top on one side for fixation, ensuring construction safety. This invention can enable efficient, fast, and convenient construction in most environments, combined with the construction characteristics of culverts and other wall structures.

[0048] The structure, workflow, and working principle of the present invention are further illustrated below with reference to a preferred embodiment:

[0049] A movable steel formwork assembly structure for concrete pouring of walls includes a fixed formwork 2, a movable formwork 1, and a guide rail 14. The fixed formwork 2 and the guide rail 14 are fixed to a concrete foundation. The movable formwork 1 includes a vertical formwork and a horizontal plate that are fixedly connected to each other. The pouring surfaces of the vertical formwork 9 of the movable formwork and the fixed formwork 2 are opposite each other. A roller frame 5 is provided on the side of the vertical formwork 9 facing away from the pouring surface. A first roller 6 that rolls with the guide rail 14 is installed on the roller frame 5. The first roller 6 is movably connected to the roller frame 5. The bottom surface of the horizontal plate 8 of the movable formwork has several grooves. The inner rolling connection includes a second roller 13; during concrete pouring, the horizontal plate 8 of the movable formwork is fixed to the concrete foundation by a detachable fastener, which is an expansion bolt 7; concrete is poured between the movable formwork 1 and the fixed formwork 2; after the concrete pouring is completed, the horizontal plate 8 of the movable formwork is separated from the expansion bolt 7, and the first roller 6 is rolled and connected to the guide rail 14. Under the action of external force, the first roller 6 rolls along the guide rail 14, and the second roller 13 rolls along the direction of the guide rail 14 on the concrete foundation, thereby moving the movable formwork 1 along the guide rail 14. The guide rail 14 is made of steel rail.

[0050] It also includes calipers 9, which are evenly provided with several slots; the movable template 9 and the fixed template 2, both of which have several locking blocks 3 that mate with the slots on their top surfaces and front and rear sides perpendicular to the pouring surface; the upper end of the locking block 3 on the top surface of both has a protrusion that restricts the upward movement of the calipers 9; the front end of the locking block 3 on the side surface of both has a protrusion that restricts the horizontal outward movement of the calipers 9. The calipers 9 are provided with graduations. Several calipers 9 are engaged with the locking blocks 3 of both, so that the pouring surfaces of both are parallel and maintain a set gap.

[0051] It also includes several tie bolts 4; the movable template 9 and the fixed template 2 are provided with several through holes A; the tie bolts 4 pass through the through holes A of the movable template 9 and the fixed template 2 and are fastened.

[0052] The first roller 6 is vertically connected to the roller frame 5. The first roller 6 rotates around its axle; the axle of the first roller 6 is fixed to the roller frame 5 through a lifting device such as a jack, and the height of the axle can be adjusted by adjusting the height of the jack.

[0053] A traction ring 11 is provided on the top surface of the fixed template 2, and a fixed pulley 12 corresponding to the traction ring 11 is provided on the top surface of the movable template 1. One end of the traction rope is connected to the traction ring 11, and the other end of the traction rope is connected to an external traction device around the fixed pulley 12. Under the drive of the traction device, the movable template 1 moves toward the fixed template 2.

[0054] A method for pouring movable concrete for culvert walls, used for pouring the walls of culverts, employs the aforementioned movable concrete pouring steel formwork assembly structure. The method includes the following steps:

[0055] First, on the already poured culvert foundation, lay steel rails at the designed locations. The rails are fixed to the culvert foundation using expansion bolts 7 or pre-embedded bolts. The horizontal plate of the fixed formwork 2 is then fixed to the culvert foundation using expansion bolts 7. The horizontal plate and vertical formwork of the fixed formwork 2 can be prefabricated as a whole or made into an L-shaped formwork, depending on project needs. The remaining side formwork is fixed to the vertical formwork of the fixed formwork 2 to form an integral fixed formwork 2. The fixed formwork 2 and rails are then fixed to the concrete foundation. The movable formwork 1 is placed on the concrete foundation, opposite the first section of the fixed formwork 2.

[0056] After the movable template 1 and the fixed template 2 are installed, one end of the traction rope is connected to the traction ring 11, and the other end of the traction rope is connected to the external traction device by winding around the fixed pulley 12. Under the drive of the traction device, the movable template 1 moves toward the fixed template 2 to adjust the gap between the pouring surfaces of the movable template 1 and the fixed template 2.

[0057] From bottom to top, several calipers 9 are clamped onto the clamping blocks 3 of the movable template 1 and the fixed template 2, so that the pouring surfaces of the movable template 1 and the fixed template 2 are parallel and maintain a set gap; the caliper 9 has a clamping groove spacing at regular intervals (which can be set according to the actual project situation) and is set with scale to maintain construction accuracy.

[0058] Both have 10 pairs of locking blocks 3 on their front and rear sides. The head of the locking block 3 is larger than the slot size; the size of the locking block 3 matches the slot size, meaning the caliper 9 must be securely installed inside the locking block 3. The caliper 9 is placed from bottom to top, with the caliper 9 at the top of the moving template 1 and the fixed template 2 placed last. The horizontal plate 8 of the moving template is fixed using expansion bolts 7.

[0059] After the movable template 1 and fixed template 2 are reinforced, tie bolts 4 are passed through the through holes A of the movable template 1 and fixed template 2 to further reinforce them. Organic board 15 is attached to the pouring surfaces of the movable template 1 and fixed template 2 on both sides. Before pouring, release oil is evenly applied to the organic board 15. After completing the above steps, concrete is poured.

[0060] After the concrete wall is poured, the formwork is removed once the concrete has reached a certain strength before the next section of the wall is poured. Here, the organic board 15 has a smooth surface and waterproof performance, which facilitates the demolding operation by the construction workers. After the concrete separates from the formwork, simply remove the calipers 9, separate the horizontal plate 8 of the movable formwork from the expansion bolts 7, and connect the first roller 6 to the guide rail 14 in a rolling engagement. Under the action of external force, the first roller 6 rolls along the guide rail 14, and the second roller 13 rolls along the direction of the guide rail 14 on the concrete foundation, thereby moving the movable formwork 1 along the rail.

[0061] Move the movable formwork 1 to the designed position and anchor it to the next fixed formwork 2. Note that the nylon board should be rinsed and coated with release oil before pouring the next section of concrete. Repeat the above steps to reinforce it before pouring again. The fixed formwork 2 can be pre-fixed, so subsequent work does not require high-altitude operations; simply move the movable formwork 1.

[0062] For locations with inconvenient construction environments where large machinery cannot easily enter, movable formwork 1 can be used on both sides, and pre-laid steel rails can be laid on both sides. Other locations can be constructed simultaneously on both sides using the above method.

[0063] The aforementioned movable template, fixed template, clamping block, tie bolt, roller frame, first roller, expansion bolt, horizontal plate of movable template, caliper, vertical template of movable template, traction ring, fixed pulley, second roller, guide rail, organic board and other structures and components can all be existing structures and components, or can be constructed using existing structures and components and conventional technical means.

[0064] The embodiments described above are only used to illustrate the technical ideas and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. The patent scope of the present invention should not be limited by these embodiments. That is, any equivalent changes or modifications made in accordance with the spirit disclosed in the present invention still fall within the patent scope of the present invention.

Under the drive of the traction device, the movable template moves toward the fixed template.

6. A method for pouring concrete for a movable wall, characterized in that, This method involves setting up a fixed template, a movable template, and guide rails; fixing the fixed template and guide rails to a concrete foundation; the movable template includes a vertical template and a horizontal plate fixedly connected to each other; ensuring the pouring surfaces of the vertical template and the fixed template face each other; a roller frame is provided on the side of the vertical template facing away from the pouring surface, and a first roller that rolls with the guide rail is installed on the roller frame, making the first roller movably connected to the roller frame; several grooves are provided on the bottom surface of the horizontal plate of the movable template, and a second roller is rolled within the grooves; during concrete pouring, the horizontal plate of the movable template is fixed to the concrete foundation by detachable fasteners; concrete is poured between the movable template and the fixed template; after the concrete pouring is completed, the horizontal plate of the movable template is separated from the detachable fasteners, allowing the first roller to roll with the guide rail. Under external force, the first roller rolls along the guide rail, and the second roller rolls along the direction of the guide rail on the concrete foundation, thereby moving the movable template along the guide rail. A traction ring is installed on the top surface of the fixed template, and a fixed pulley corresponding to the traction ring is installed on the top surface of the movable template; calipers are installed with several evenly spaced slots; for both the movable and fixed templates, several locking blocks that mate with the slots are installed on their top and front / back sides perpendicular to the pouring surface; this method includes the following steps: Step 1: Fix the fixed template and track to the concrete foundation, and place the movable template on the concrete foundation, opposite to the first fixed template section; Step 2: Connect one end of the traction rope to the traction ring, and connect the other end of the traction rope to the external traction device by winding around the fixed pulley. Driven by the traction device, move the moving template toward the fixed template to adjust the gap between the pouring surfaces of the moving template and the fixed template. Step 3: From bottom to top, attach several calipers to the clamps of the moving template and the fixed template to make the pouring surfaces of the moving template and the fixed template parallel and maintain the set gap. Step 4: Pour concrete between the movable formwork and the fixed formwork; Step 5: After the concrete pouring is completed, remove the detachable fixing parts on the horizontal plate of the movable formwork, so that the first roller rolls into contact with the guide rail, move the movable formwork to the position opposite to the next fixed formwork section, and then disengage the first roller from the guide rail. Step 6: Repeat steps 2 to 5 until one side of the wall is poured.
