Description

Technical Field

[0001] This utility model relates to a building construction structural component, and more particularly to a reusable formwork mounting structural component, belonging to the field of building construction technology. Background Technology

[0002] Construction of tall structures must proceed gradually from the bottom upwards. After the bottom layer of reinforcing steel is tied, the bottom layer of formwork is erected, and then the bottom layer of concrete is poured. After the bottom layer of concrete has cured and reached its strength, the next layer of reinforcing steel is tied, the next layer of formwork is erected, and the next layer of concrete is poured. After the concrete of that layer has cured and reached its strength, the next layer of reinforcing steel is tied, and so on.

[0003] Traditional concrete pouring methods for tall structures typically include formwork flipping, slipform, climbing formwork, cantilever scaffolding, and roller formwork. Formwork flipping involves a multi-layered, upward-rotating formwork process. Because the concrete is statically formed within the formwork, the surface is smooth. Each pour typically reaches a height of 4.5 or 6 meters. Due to the significant lateral pressure of the concrete, tie rods are needed on the formwork to prevent it from bursting. During the formwork flipping process, the lower layer of concrete must reach a strength of at least 15 MPa before the lower formwork can be removed. To enhance the bond between the two layers, the top layer of concrete needs to be roughened before removing the lower formwork. Then, the lower formwork is raised to the top, and this process is repeated until construction is complete. Because of the waiting time for the lower concrete to reach high strength, the need for tie rods on the formwork, and the roughening process, the construction speed is slow, requiring four days to complete one cycle, with an average daily concrete pouring height of only about 1 meter. In addition, the process of flipping the formwork poses a significant safety risk. When the lower formwork is flipped, it is held by a tower crane. When the connection with the upper formwork is released, the formwork is prone to being thrown backward due to the change in the center of gravity, which threatens the personal safety of the demolition personnel.

[0004] Chinese utility model patent CN 108560992B discloses a construction equipment and concrete pouring method for tall structures. The method involves three layers of formwork. A middle platform is located below the lower formwork, and a bottom platform is located at a distance below the middle platform. The middle and bottom platforms are supported against the concrete wall by wall-mounted rollers. The outer ends of the bottom and middle platforms are connected by an external lifting frame. The upper end of the external lifting frame extends upward and is fixedly connected to a top platform. The lower end of the top platform is spaced apart from the top of the upper formwork. Multiple hydraulic jacks are mounted on the upper end of the top platform, each mounted on a supporting steel column. The lower ends of each supporting steel column extend to the bottom of the poured concrete. A formwork turning channel is provided between the opposing ends of the external lifting frame and the formwork. A small formwork turning trolley supported on guide rails is located on the top platform. This technical solution still has the following defects:

[0005] 1. Multiple supporting steel columns need to be pre-embedded in the structure, and each supporting steel column extends from the bottom of the structure to above the top of the structure, which consumes a lot of materials and increases construction costs.

[0006] 2. Large components such as a massive top platform, top platform columns, loading beams, and top platform column sleeves, which bear the weight of all lifting trusses, are required, increasing construction costs. In addition, for structures with high requirements for external dimensions, such as bridge piers, angle steel must be installed at each corner. The angle steel at the four corners is connected by crossbeams to form a cuboid frame. This cuboid frame must be hoisted into place before the steel bars are tied. Due to the height of the cuboid frame, it interferes with the top platform and loading beams, making it impossible to prefabricate and install the cuboid frame. Utility Model Content

[0007] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0008] In view of the problems existing in the above and / or prior art, this utility model is proposed.

[0009] The purpose of this utility model is to overcome the problems existing in the prior art and provide a reusable flip-form hanging structure component that simplifies the structure, eliminates the need for large support columns and top platforms, utilizes pre-embedded climbing cones and hanging seats for load bearing, reduces costs and material consumption, and provides fast concrete pouring speed and high construction safety factor.

[0010] To solve the above technical problems, this utility model provides a reusable formwork mounting structure, including a pre-embedded climbing cone embedded in concrete. The pre-embedded climbing cone includes a cone body, an embedded screw rod, and an embedded plate. The cone body is thicker on the outside and thinner on the inside. The outer end of the cone body has a large-diameter screw hole at its center, and the inner end of the cone body has a small-diameter screw hole at its center. The embedded screw rod is screwed into the small-diameter screw hole, and the inner end of the embedded screw rod is screwed into the central boss of the embedded plate. The embedded screw rod and the embedded plate are pre-embedded deep in the concrete. A mounting bracket is fixed to the outer wall of the concrete, and the mounting bracket is connected to the pre-embedded climbing cone by a load-bearing screw.

[0011] Furthermore, the bracket includes a bracket base plate, the upper part of which is symmetrically provided with bracket fixing holes. The load-bearing screws pass through the bracket fixing holes and are screwed into the large-diameter screw holes of the cone to fix the bracket base plate to the outer wall of the concrete body. Two pairs of bracket upper lugs are symmetrically welded to the upper part of the outer wall of the bracket base plate, and a main load-bearing upper pin is inserted into the main pin hole of the upper lug of each pair of bracket upper lugs. Two pairs of bracket lower lugs are symmetrically welded to the lower part of the outer wall of the bracket base plate, and the distance between the two pairs of bracket lower lugs is greater than the distance between the two pairs of bracket upper lugs. A main load-bearing lower pin is inserted into the main pin hole of the lower lug of each pair of bracket lower lugs.

[0012] Furthermore, safety pin holes are provided above the main pin holes of the upper and lower support ears of the bracket.

[0013] Furthermore, the cone is wrapped with a layer of adhesive tape, and a pair of countersunk holes are provided on the outer end face of the cone, through which the cone can be reversed and removed for reuse.

[0014] Compared with the prior art, the present invention has achieved the following beneficial effects: 1. It eliminates the need to pre-embed multiple supporting steel columns in the structure in addition to the concrete structure, which greatly reduces material consumption and construction costs.

[0015] 2. Traditional systems require the support of the entire lifting frame, top platform, and middle platform, resulting in large components such as the top platform, top platform columns, loading beams, and top platform column sleeves, which further increases the weight and manufacturing cost. In contrast, the weight of the entire system is borne only by small hanging brackets and embedded climbing cones, eliminating the need for large components such as the top platform, further reducing material consumption and construction costs.

[0016] 3. The pre-embedded climbing cone can fix both the formwork and the hanging base. The cone and the hanging base can be reused as a whole, further reducing the consumption of accessories and reducing construction costs. Attached Figure Description

[0033] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0035] like Figures 1 to 5 As shown, the reusable formwork mounting structure of this utility model includes a pre-embedded climbing cone 1 and a mounting base 3. Before pouring, the pre-embedded climbing cone 1 is pre-embedded in the concrete. The pre-embedded climbing cone 1 includes a cone body 1a, an embedded screw rod 1b, and an embedded plate 1c. The cone body 1a is thicker on the outside and thinner on the inside. A large-diameter screw hole is provided at the center of the outer end of the cone body 1a. A load-bearing screw is screwed into the large-diameter screw hole to fix the outer end of the cone body to the formwork 2. A small-diameter screw hole is provided at the center of the inner end of the cone body 1a. The embedded screw rod 1b is screwed into the small-diameter screw hole. The inner end of the embedded screw rod 1b is screwed into the central boss of the embedded plate 1c. The embedded screw rod 1b and the embedded plate 1c are pre-embedded deep in the concrete.

[0036] The cone 1a is fixed to the working surface of the panel 2a of the template 2 by a load-bearing screw. The outer periphery of the cone 1a and the root where it connects to the embedded bolt 1b are wrapped with a layer of adhesive tape to isolate it from the concrete. After the concrete is poured, the pre-embedded climbing cone 1 is embedded into the concrete body, with the outer end face of the cone 1a facing outwards to facilitate the fixing of the hanger 3. The outer end face of the cone 1a is provided with a pair of countersunk holes. After the work is completed, the cone 1a can be reversed and removed through the countersunk holes for easy reuse.

[0037] Each layer of formwork 2 includes a panel 2a, secondary back ribs 2b, and main back ribs 2c. Each secondary back rib 2b extends vertically, is parallel to each other, and is fixed to the back of the panel 2a. Each main back rib 2c extends horizontally, is parallel to each other, and is fixed to the back of the secondary back ribs 2b. The front of each panel 2a encloses the outer or inner outline of the structure. The formwork 2s located on opposite sides of the concrete are connected and locked together by long tie rods to prevent deformation and ensure the accurate dimensional shape of the concrete.

[0038] like Figures 3 to 5 As shown, the bracket 3 includes a bracket base plate 3a. Three bracket fixing holes 3a1 are symmetrically arranged on the upper part of the bracket base plate 3a. Load-bearing screws pass through the corresponding bracket fixing holes 3a1 and are screwed into the large-diameter screw holes of the corresponding pre-embedded climbing cones 1, fixing the bracket base plate 3a to the concrete outer wall. Two pairs of upper bracket lugs 3b are symmetrically welded to the upper part of the outer wall of the bracket base plate 3a, and two pairs of lower bracket lugs 3c are symmetrically welded to the lower part of the outer wall of the bracket base plate 3a. The distance between the two pairs of lower bracket lugs 3c is greater than the distance between the two pairs of upper bracket lugs 3b, and the lower bracket lugs 3c are located outside the projection of the upper bracket lugs 3b.

[0039] Each lower support lug 3c and upper support lug 3b of the bracket is provided with a 40mm diameter main pin hole at its lower part, and a 16mm diameter safety pin hole is provided above each main pin hole. A main load-bearing upper pin 3d is inserted into the main pin hole 3b1 of the upper support lug 3b, and the main load-bearing upper pin 3d of the upper support lug 3b is used to support the inner truss 4. A main load-bearing lower pin 3e is inserted into the main pin hole 3c1 of the lower support lug 3c, and the main load-bearing lower pin 3e of the lower support lug 3c is used to support the outer truss 5.

[0040] like Figures 6 to 8 As shown, the inner truss 4 includes an inner truss base 4a and an inner truss frame 4b. The bottom of the inner truss frame 4b is fixedly connected to the outer end of the inner truss base 4a and extends upward. The top of the inner truss frame 4b is higher than the total height of the two layers of templates.

[0041] A pair of inner truss rollers 4c are fixed to the lower part of the inner end of the inner truss base 4a, and are supported on the concrete outer wall by the inner truss rollers 4c.

[0042] A pair of inner truss lugs 4d are welded to the upper part of the inner end of the inner truss base 4a. The bottom of the inner truss lugs 4d has a downward-opening groove, and the lower end of the groove expands outward to facilitate the insertion of the main load-bearing upper pin 3d. The middle part of the inner truss lugs 4d has an inner truss lug safety pin hole 4d1.

[0043] When the inner truss lug 4d reaches above the main pin hole 3b1 of the upper support lug 3b of the bracket, the main bearing upper pin 3d is inserted into the main pin hole 3b1 of the upper support lug. Then the inner truss 4 drops a short distance so that the groove at the bottom of the inner truss lug 4d is supported on the main bearing upper pin 3d. When the main bearing upper pin 3d slides to the root of the groove, the inner truss 4 obtains stable support.

[0044] Insert the safety pin of the upper support lug 3b into the safety pin hole 3b2 of the upper support lug 3b and the safety pin hole 4d1 of the inner truss lug 3d1 to lock the inner truss 4 onto the support lug 3 and ensure safety.

[0045] The outer truss 5 includes an outer truss base 5a and an outer truss frame 5b. The bottom of the outer truss frame 5b is fixedly connected to the outer end of the outer truss base 5a and extends upward. The outer truss base 5a is fitted around the outer periphery of the inner truss base 4a from top to bottom, and the outer truss frame 5b is fitted around the outer periphery of the inner truss frame 4b from top to bottom. The two are fitted with a clearance, so that the outer truss 5 can slide upward along the inner truss frame 4b as a whole.

[0046] A pair of outer truss rollers 5c are fixed to the lower part of the inner end of the outer truss base 5a and supported on the concrete outer wall by the outer truss rollers 5c; a pair of outer truss lugs 5d are welded to the upper part of the inner end of the outer truss base 5a, and the bottom of the outer truss lugs 5d is provided with a downward-opening groove, and the lower end of the groove expands outward to facilitate the insertion of the main load-bearing pin 3e.

[0047] The outer truss frame 5b facing the concrete is also provided with a widened frame 5f, which is used to accommodate the lifting cylinder 6. A formwork turning channel is left between the widened frame 5f of the outer truss 5 and the formwork 2. An inner truss hinge seat 4e is welded to the upper part of the inner truss base 4a, and an outer truss hinge seat 5e is welded to the middle of the outer truss frame 5b. The outer truss hinge seat 5e is located directly above the inner truss hinge seat 4e, and the two ends of the lifting cylinder 6 are hinged between the inner truss hinge seat 4e and the outer truss hinge seat 5e.

[0048] When the outer truss lug 5d reaches above the main pin hole 3c1 of the lower support lug 3c, the main bearing pin 3e is inserted into the main pin hole 3c1 of the lower support lug 3c. Then the outer truss 5 drops a short distance so that the groove at the bottom of the outer truss lug 5d is supported on the main bearing pin 3e. When the main bearing pin 3e slides to the root of the groove, the outer truss 5 obtains stable support.

[0049] Insert safety pins into the safety pin holes 3c2 of the lower support lug 3c of the hanger and 5d1 of the outer truss hanger to lock the outer truss 5 onto the hanger 3.

[0050] The following are examples illustrating the operational steps involved in this formwork mounting structure:

[0051] 1. After the bottom two layers of concrete have reached their strength, remove the bottom formwork and the load-bearing screws connecting it to the pre-embedded climbing cone 1, and fix the hanging bracket 3 on the outside of the pre-embedded climbing cone 1 in the bottom concrete.

[0052] 2. Install the inner truss 4 on the outside of the bottom concrete. The lower part of the inner end of the inner truss base 4a is supported on the outer concrete wall by the inner truss roller 4c. The bottom groove of the inner truss hanging ear 4d is inserted into the main load-bearing upper pin 3d. Then, insert the upper support ear safety pin into the upper support ear safety pin hole 3b2 and the inner truss hanging ear safety pin hole 4d1 to lock the inner truss 4 onto the bottom hanging seat 3.

[0053] 3. The outer truss 5 is fitted over the inner truss 4. The lower part of the inner end of the outer truss base 5a is supported on the concrete outer wall by the outer truss roller 5c. The bottom groove of the outer truss hanging lug 5d is inserted into the main load-bearing lower pin 3e. Then, the lower support lug safety pin is inserted into the lower support lug safety pin hole 3c2 and the outer truss hanging lug safety pin hole 5d1 to lock the outer truss 5 onto the bottom hanging lug 3.

[0054] 4. Tie the third layer of reinforcing bars, install the third layer of formwork, fix the third layer of pre-embedded climbing cones at the corresponding positions of the third layer of formwork, and then pour the third layer of concrete.

[0055] 5. Hinge the two ends of the lifting cylinder 6 between the inner truss hinge seat 4e and the outer truss hinge seat 5e.

[0056] 6. Workers remove the second layer of formwork, lift the second layer of formwork to the fourth layer, and then complete the installation of the fourth layer of formwork and the fourth layer pre-embedded climbing cone 1.

[0057] 7. Fix the bracket 3 to the outside of the pre-embedded climbing cone in the second layer of concrete, remove the safety pin of the lower support ear, extend the piston rod of the lifting cylinder 6 to lift the outer truss 5 to the height of one layer of concrete, and then make the outer truss bracket 5d support the main bearing pin 3e of the second layer bracket, insert the safety pin of the lower support ear again, and lock the outer truss 5 on the second layer bracket 3.

[0058] 8. Remove the safety pin of the upper support ear, and the piston rod of the lifting cylinder 6 will retract, raising the inner truss 4 to the height of one layer of concrete. The inner truss hanging ear 4d is supported on the main bearing pin 3d of the second layer bracket. Insert the safety pin of the upper support ear again to lock the inner truss 4 on the second layer bracket 3.
