Description

Technical Field

[0001] The present invention relates to the field of formwork support for building construction, and specifically to a formwork reinforcement device for the secondary structure of a building. Background Art

[0002] The secondary structure of a building is constructed after the completion of the primary structure (referring to the load-bearing components of the main structure). Relative to the load-bearing structure, the secondary structure is often a non-load-bearing structure and an enclosure structure, such as construction columns, lintels, water-stop inverted beams, parapets, coping, infill walls, and partition walls, etc.

[0003] A construction column refers to a reinforced concrete construction column that should be set in the walls of a multi-story brick-concrete structure building in order to enhance the integrity and stability of the building, and is connected to the ring beams on each floor to form a spatial frame that can resist bending and shear. It is an effective measure to prevent the collapse of the house. The setting positions of construction columns are at the four corners of the exterior wall, the intersection of the transverse wall and the exterior longitudinal wall at the staggered floor part, both sides of larger openings, the intersection of the interior and exterior walls of large rooms, etc. In addition, due to different numbers of floors and different seismic intensities of the house, the setting requirements of construction columns are also inconsistent. With the increase of seismic intensity and the number of floors, the cross-section and steel grade of the construction columns at the four corners of the building can be appropriately increased.

[0004] Construction columns are often constructed by pouring, and the formwork is supported by constructing formwork around it. However, in the process of constructing construction columns with the existing formwork support method, the following problems often exist:

[0005] Due to the position and seismic intensity requirements of the construction column, a steel bar skeleton is often embedded in it. The existing formwork support method often uses through bolts for locking, which increases the loss of steel and the difficulty of subsequent formwork removal operations. Moreover, the layout position of the through bolts is often blocked by the embedded steel bar skeleton and forced to give way, resulting in poor formwork support strength. In addition, it is difficult to enhance the fluidity of the concrete inside the existing support formwork during the support process, resulting in difficulty in effectively filling the corner area inside the construction column with concrete, and reducing the overall structural strength after the construction column is poured. Summary of the Invention

[0018] The beneficial effects of the present invention:

[0019] (1) For the formwork reinforcement device for the secondary structure of a building described in the present invention, through the combined support base, support rods and reinforcing ribs, it can adapt to the sizes of construction columns at different positions in the building and the width changes of the construction site. Through the stable support between the top and the ground of the wall in the construction column area, it avoids the influence of the position of the internal steel bars during the traditional through - bolt locking method. While saving materials, it also improves the efficiency of the later formwork removal operation. Through the combined deviation - correcting rods and pressing plates, the two ends and the middle part of the formwork can be jointly positioned and assisted in vibration reduction, avoiding the deflection and shaking of the formwork caused by the impact of concrete during the pouring process, and improving the flatness of the wall construction column after pouring.

[0020] (2) For the formwork reinforcement device for the secondary structure of a building according to the present invention, through multiple preset vibration cones and the conical structure at the end of the vibration cone itself, during the process of penetrating the concrete liquid surface layer, the concrete liquid surface can be squeezed to generate fluctuations. Combining with the elastic contraction and expansion process of the airbag, the vibration amplitude of the concrete liquid surface inside the wall structural column can be increased, facilitating the flow of concrete into the corner area inside the wall structural column during the pouring process, and keeping the concrete in each area at an appropriate area density, thereby improving the overall structural strength of the structural column after pouring.

[0021] (3) For the formwork reinforcement device for the secondary structure of a building according to the present invention, through the annular penetration of the cable, the vibration cone can be quickly removed after pouring. Through the magnetic attraction between the magnetic ring and the pull rod, the height position of the vibration cone can be locked during the batch pouring process, preventing the vibration cone from sinking into the concrete and solidifying.

Specific embodiments

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] An embodiment of the present invention, refer to Figure 1 , Figure 2 and Figure 4, A formwork reinforcement device for the secondary structure of a building, including a formwork 1, a support rod 2, and a pouring port 3. The formwork 1 is located on both sides of the wall 00 structural column. The formwork 1 is stacked sequentially from bottom to top, and the inner sides of the formwork 1 are all in contact with the wall surface. The support rod 2 is fitted and installed on the outer side of the formwork 1, and both ends of the support rod 2 are respectively abutted against the ground and the top of the wall. A pouring port 3 is detachably installed in the middle of the formwork 1 at the top of the stacked state. The middle part of the support rod 2 is a hollow groove structure, and support seats 4 are detachably installed at both ends of the support rod 2. The longitudinal section of the pouring port 3 is a trapezoidal structure.

[0039] As an embodiment of the present invention, as Figure 7 , Figure 8 , Figure 10 and Figure 12 shown, the support seat 4 is a "T" - shaped structure composed of a horizontal part 5 and a vertical part 6. The horizontal part 5 and the vertical part 6 are slidably connected. A tightening bolt 61 is installed in the middle of the vertical part 6 by means of threaded cooperation, and the end of the tightening bolt 61 abuts against the horizontal part 5. The end of the vertical part 6 is inserted into the hollow groove at the end of the support rod 2 by means of sliding fit, and a plurality of pairs of through - grooves 62 that communicate with each other are symmetrically arranged on the side wall of the end of the vertical part 6 and the support rod 2. A positioning bolt 63 is detachably inserted into one pair of through - grooves 62. Inner screw holes 51 are symmetrically arranged at both ends of the horizontal part 5. A strengthening seat 7 is placed on the ground near the lower part of the wall 00. An inner screw hole 51 with the same structure as that on the horizontal part 5 is opened in the middle of the strengthening seat 7. An adjustable - distance rod 71 is jointly installed between the strengthening seat 7 and the horizontal part 5 through the inner screw holes 51. The upper end of the strengthening seat 7 is hingedly installed with a strengthening rib 72. The strengthening rib 72 obliquely points to the support rod 2 and is fixedly connected to the middle part of the support rod 2. Friction pads 52 are fitted and installed on the end faces of the horizontal part 5, and the friction pads 52 are respectively in contact with the top of the wall and the ground. Hanging rings 53 are hingedly installed at the ends of the horizontal part 5 and the ends of the strengthening seat 7, and a steel cable 54 is connected between the hanging ring 53 on the strengthening seat 7 and the hanging ring 53 on the horizontal part 5 at the bottom of the wall 00.

[0040] During actual operation, first, the staff assembles the support rod 2 and the support base 4. During this process, the end of the vertical part 6 is inserted into the hollow groove at the end of the support rod 2. After the insertion is completed, the relative position between the vertical part 6 and the support rod 2 is locked through the clamping fit between the positioning bolt 63 and the through groove 62. During the installation of the vertical part 6, by adjusting the insertion depth of the vertical part 6, the horizontal part 5 is kept at an appropriate distance from the end of the support rod 2, so that the length formed by the splicing of the support rod 2, the horizontal part 5 and the vertical part 6 is close to the positions of the top of the wall and the ground near the position of the wall 00. Subsequently, the staff uses the lifting ring 53 to tow the assembled support rod 2 as a whole to the position of the structural column of the wall 00, and keeps the support rod 2 vertically placed at the predetermined positions on both sides of the structural column of the wall 00. After the support rod 2 is placed, the friction pads 52 provided on the end face of the horizontal part 5 are respectively attached to the top of the wall and the ground. Subsequently, the staff rotates the tightening bolt 61. Through the thread engagement, during the rotation of the tightening bolt 61, its end extends from the vertical part 6 towards the horizontal part 5. Then, after being blocked by the horizontal part 5, the horizontal part 5 is pushed to move as a whole, so that the friction pad 52 closely adheres to the top of the wall or the ground it contacts. In addition, by tightening the tightening bolt 61, the support rod 2 placed in the vertical state can also be fastened, so that it is supported on both sides of the structural column and effectively prevents the support rod 2 from tilting or deflecting;

[0041] After the position of the support rod 2 is fixed, the staff selects a distance-adjusting rod 71 with an appropriate length according to the width of the construction site at the construction operation position, and places the reinforcement base 7 parallel to the ground close to the support base 4. Subsequently, the distance-adjusting rod 71 is screwed into the internal thread hole 51, thereby locking the relative position between the support base 4 and the reinforcement base 7. Then, the two lifting rings 53 on the support base 4 and the reinforcement base 7 are connected and fixed through the steel cable 54 to further enhance the stability of the connection between the support base 4 and the reinforcement base 7. Subsequently, the staff rotates the reinforcing rib 72 to make the reinforcing rib 72 inclined towards the support rod 2, and fixes and connects the end of the reinforcing rib 72 to the middle of the support rod 2 through bolts. At this time, through the reinforcing rib 72, the support rod 2, the steel cable 54 and the distance-adjusting rod 71, a triangular stable structure can be jointly formed to assist in supporting the support rod 2 and ensure the vertically placed state of the support rod 2.

[0042] As an implementation manner of the present invention, such as Figure 3 、 Figure 7 、 Figure 10 and Figure 11As shown in the figure, on the side of the support rod 2 close to the formwork 1, deviation-correcting grooves 21 are evenly arranged from bottom to top. At both the upper and lower ends of the notch of the deviation-correcting groove 21, baffle plates 22 are fixedly installed. The baffle plates 22 are located inside the hollow groove of the support rod 2, and a group of deviation-correcting shafts 23 are commonly installed between two adjacent baffle plates 22. Torsion springs are connected between the deviation-correcting shafts 23 and the baffle plates 22. A deviation-correcting rod 24 is fixedly installed on the deviation-correcting shaft 23 at the position close to the edge of the formwork 1, and a pressing plate 25 is fixedly installed on the deviation-correcting shaft 23 at the position close to the center of the formwork 1. The deviation-correcting rod 24 and the pressing plate 25 are arranged on the same line, and meshing teeth 26 that mesh with each other are symmetrically arranged at the adjacent ends of the deviation-correcting rod 24 and the pressing plate 25. The end of the deviation-correcting rod 24 is exposed on the side wall of the end of the formwork 1, and an arc-shaped surface that is hooked and abutted against the side wall of the formwork 1 is arranged at the end of the deviation-correcting rod 24. A damping ring 250 is evenly installed on one side wall of the pressing plate 25, and the damping rings 250 are all abutted against the side wall of the formwork 1.

[0043] During specific operation, after the position of the support rod 2 is determined, the staff uses a rubber hammer to sequentially insert multiple formworks 1 from bottom to top into the reserved gap between the support rod 2 and the wall 00. In the initial state, the deviation-correcting rod 24 and the pressing plate 25 are on the same straight line under the torsion force of the torsion spring, and the meshing teeth 26 on the deviation-correcting rod 24 and the pressing plate 25 mesh with each other. Thereafter, during the installation of the formwork 1, the formwork 1 enters along the arc-shaped side wall at the end of the deviation-correcting rod 24. Subsequently, under the abutting action of the formwork 1, its end gradually deflects in the direction away from the wall 00. And during the deflection of the deviation-correcting rod 24, through the meshing action of the meshing teeth 26, the pressing plate 25 deflects synchronously. When the formwork 1 enters the predetermined position, the arc surface at the end of the deviation-correcting rod 24 rotates back after losing the blocking and abutting action of the formwork 1, and the pressing plate 25 rotates synchronously through the meshing action of the meshing teeth 26. After the deviation-correcting rod 24 rotates in place, the inner side of its arc surface is hooked and abutted against the end surface of the formwork 1, thereby fixing the left and right positions of the formwork 1 between the support rod 2 and the wall 00. After the pressing plate 25 is reset, the damping rings 250 on its side surface are all abutted against the side wall of the formwork 1 and press it. In this way, the installation and positioning operation of the formwork 1 is sequentially carried out from bottom to top. When the last formwork 1 at the upper part is installed, the staff installs the pouring port 3 into the upper formwork 1.

[0044] As an implementation manner of the present invention, as Figure 2 、 Figure 6 、 Figure 7 、 Figure 9 and Figure 13As shown, scraping cylinders 31 are symmetrically installed on both sides of the middle of the pouring opening 3. A cable 32 is slidably installed through the inner side of the scraping cylinder 31, and the cable 32 is in contact with the inner wall of the scraping cylinder 31. Guide cylinders 33 are symmetrically installed at the middle part of the formwork 1 near the lower part of the wall 00 and the upper end of the pouring opening 3. The middle part of the cable 32 slidably penetrates through the guide cylinders 33 on the formwork 1 and the pouring opening 3 respectively. A vibration cone 34 is detachably installed on the cable 32. The cable 32 is an "open" - shaped surrounding structure. The cable 32 passes through and surrounds the formwork 1 through the guide cylinders 33. The vibration cone 34 is located inside the formwork 1. A pull rod 321 is detachably installed on the cable 32 below the outer side of the pouring opening 3. A magnetic attraction ring 251 is fixedly installed at the end of the pressing plate 25. The end of the pull rod 321 is a magnetic columnar structure attracted to the magnetic attraction ring 251, and a notch for sliding fit with the end of the pull rod 321 is formed on the magnetic attraction ring 251. The vibration cone 34 is a three - section structure. The upper and lower sections of the vibration cone 34 are both conical structures. A connecting rod 341 is jointly installed between the upper and lower sections of the vibration cone 34 in a sliding fit manner, and a tension spring 342 is jointly connected between the upper and lower sections of the vibration cone 34. The middle part of the vibration cone 34 is an elastic airbag 343 structure, and the upper and lower sides of the airbag 343 are hermetically attached to the upper and lower sections of the vibration cone 34 respectively. Card slots are reserved at the ends of the conical sections of the upper and lower parts of the vibration cone 34. The two ends of the cable 32 are respectively clamped in the card slots at the ends of the upper and lower parts of the vibration cone 34. A clamping block 344 is installed in the card slot in a sliding fit manner. The clamping block 344 is made of magnetic material. One end of the clamping block 344 abuts against the cable 32, and the other end of the clamping block 344 is connected to the inner wall of the card slot through a compression spring 345.

[0045] During the actual operation, at the initial stage of installing the pouring opening 3, the staff pre-assembles the scraping cylinder 31 and the pouring opening 3 in advance. After the assembly is completed, the cable 32 passes through the scraping cylinder 31. Subsequently, the guiding cylinders 33 are sleeved and installed on the pouring opening 3 and the formwork 1 at the lowermost position respectively, and the cable 32 passes through the guiding cylinders 33 at the upper and lower positions in sequence. After passing through, the staff attaches the existing permanent magnet to the end of the vibration cone 34. Through the adsorption between the permanent magnet and the clamping block 344, the clamping block 344 is in a contracted state, so that the clamping groove at the end of the vibration cone 34 is in an open state. Then, the staff respectively clamps the two ends of the cable 32 in the clamping grooves at the two ends of the vibration cone 34, and releases the adsorption of the permanent magnet on the clamping block 344. Subsequently, under the elastic reset push of the compression spring 345, the clamping block 344 is exposed and abuts against the side wall of the cable 32, so that the cable 32 is locally bent in the clamping groove, thereby increasing the frictional resistance between the cable 32 and the clamping groove, realizing the clamping connection between the cable 32 and the vibration cone 34. Then, the cable 32 surrounds the inner and outer sides of the formwork 1 in a "mouth" shape. Subsequently, the staff pushes the pull rod 321 upward, so that the cable 32 rotates in the reverse direction. The rotation of the cable 32 drives the vibration cone 34 to move to the bottom of the cavity of the wall 00 structural column on the inner side of the formwork 1;

[0046] Subsequently, the concrete is filled into the pouring opening 3 through the existing pouring pipeline. The concrete then flows under the action of gravity and the inclined guiding action of the pouring opening 3 to the bottom of the wall 00 structural column, and fills the steel bars 01 embedded in the wall 00 structural column. When the concrete slowly accumulates and rises in the wall 00 structural column, the staff pulls the pull rod 321 and the cable 32 to make the vibration cone 34 reciprocally penetrate and move up and down on the concrete liquid surface. Due to the tapered structures at both ends of the vibration cone 34, when the vibration cone 34 penetrates the concrete liquid layer, the concrete liquid surface in its nearby area is squeezed and fluctuates. At the same time, due to the pulling of the cable 32 and the damping change of the vibration cone 34 itself up and down on the concrete liquid surface, the tapered structures at both ends of the vibration cone 34 approach or move away from each other intermittently under the guiding action of the connecting rod 341, so that the airbag 343 is reciprocally pulled and deformed. The contraction and expansion process of the airbag 343 further intensifies the fluctuation effect of the concrete in the area near the vibration cone 34;

[0047] Through the preset multiple groups of vibration cones 34, different areas of the concrete page layer can work together to make the concrete liquid surface in the wall 00 structural column vibrate. Through the autonomous vibration of the concrete, it is convenient for the concrete to flow into the corner area inside the wall 00 structural column during the pouring process, and the concrete in each area can maintain an appropriate regional density, thereby improving the overall structural strength of the structural column after pouring. When the staff pulls down the pull rod 321, the height position of the vibration cone 34 is judged by the height position of the pull rod 321 and the resistance during the pull rod 321. When the concrete pouring process is carried out in batches, the height position of the vibration cone 34 can also be locked by the magnetic attraction between the magnetic ring 251 and the pull rod 321 to prevent the vibration cone 34 from sinking into the concrete and consolidating.

[0048] When the concrete pouring is completed, the vibration cone 34 moves to the upper part of the wall 00 under the pulling action of the staff. Then, the staff uses a permanent magnet to release the connection between the vibration cone 34 and the cable 32, and takes out the vibration cone 34 and the cable 32. Then, the concrete is allowed to solidify naturally, and after the solidification is completed, the support rod 2 and the formwork 1 are removed in turn.

[0049] When working:

[0050] The first step: First, the staff assembles the supporting rod 2 and the supporting seat 4. During this process, the end of the vertical part 6 is inserted into the hollow groove at the end of the supporting rod 2. After the insertion is completed, the relative position between the vertical part 6 and the supporting rod 2 is locked by the snap-fit ​​cooperation between the positioning bolt 63 and the through groove 62. Then, the staff drags the assembled supporting rod 2 as a whole to the structural column position of the wall 00 through the lifting ring 53, and keeps the supporting rod 2 in a vertical position at the predetermined positions on both sides of the structural column of the wall 00. After the supporting rod 2 is placed, the friction pad 52 arranged on the end face of the horizontal part 5 is respectively fitted with the top of the wall and the ground. Then, the staff turns the tightening bolt 61. By locking the tightening bolt 61, the supporting rod 2 placed in the vertical state can also be tightened, so that it is supported on both sides of the structural column and effectively prevents the supporting rod 2 from tilting or deflecting.

[0051] Step 2: After the position of the support rod 2 is fixed, the staff selects a distance-adjusting rod 71 with an appropriate length according to the width of the construction site at the construction operation position, and places the reinforcement seat 7 parallel to the ground close to the support seat 4. Subsequently, the distance-adjusting rod 71 is screwed into the internal threaded hole 51, thereby locking the relative position between the support seat 4 and the reinforcement seat 7. Then, the two lifting rings 53 on the support seat 4 and the reinforcement seat 7 are connected and fixed by a steel cable 54 to further enhance the stability of the connection between the support seat 4 and the reinforcement seat 7. Then, the staff rotates the reinforcing rib 72 so that the reinforcing rib 72 is inclined towards the support rod 2, and the end of the reinforcing rib 72 is fixedly connected to the middle of the support rod 2 by bolts. At this time, a triangular stable structure can be jointly formed by the reinforcing rib 72, the support rod 2, the steel cable 54 and the distance-adjusting rod 71, and the support rod 2 is assisted to support, ensuring the vertical placement state of the support rod 2.

[0052] Step 3: After the position of the support rod 2 is determined, the staff uses a rubber hammer to sequentially insert multiple templates 1 from bottom to top into the reserved gap between the support rod 2 and the wall 00. Subsequently, the staff assembles the scraping cylinder 31 and the pouring port 3, and after the assembly is completed, the cable 32 passes through the scraping cylinder 31. When the last template 1 at the upper part is installed, the staff installs the pouring port 3 into the upper template 1.

[0053] Step 4: The staff respectively installs and sleevs the guide cylinders 33 on the pouring port 3 and the template 1 at the lowermost position, and makes the cable 32 sequentially pass through the guide cylinders 33 at the upper and lower positions. After the penetration is completed, the staff respectively clamps the two ends of the cable 32 into the card slots at the two ends of the vibration cone 34, so that the cable 32 surrounds and penetrates the inner and outer sides of the template 1 in a "mouth" shape. Then, the staff pushes the pull rod 321 upward, thereby causing the cable 32 to reverse and rotate. The rotation of the cable 32 drives the vibration cone 34 to move to the bottom of the cavity of the wall 00 structural column inside the template 1.

[0054] Step 5: Fill the concrete into the pouring port 3 through the existing pouring pipeline. The concrete then flows under the action of gravity and the inclined guiding action of the pouring port 3 towards the bottom of the wall 00 structural column, and buries the embedded steel bars 01 in the wall 00 structural column. When the concrete slowly accumulates and rises in the wall 00 structural column, the vibration cone 34 is pulled by the staff on the tie rod 321 and the cable 32 to reciprocate and penetrate up and down on the concrete liquid surface. Through the preset multiple groups of vibration cones 34, they can work together at different regional positions on the concrete surface layer, thereby causing the concrete liquid surface in the wall 00 structural column to vibrate. Through the self-vibration of the concrete, it is convenient for the concrete to flow into the corner area inside the wall 00 structural column during the pouring process, and keep the concrete in each area at an appropriate regional density, improving the overall structural strength of the structural column after pouring.

[0055] Step 6: After the concrete pouring is completed, the vibration cone 34 is moved to the upper part of the wall 00 under the pulling action of the staff. Subsequently, the staff uses a permanent magnet to release the connection between the vibration cone 34 and the cable 32, and takes out the vibration cone 34 and the cable 32. Then, wait for the concrete to solidify naturally, and after the solidification is completed, remove the support rod 2 and the formwork 1 in sequence.
