Description

Technical Field

[0001] This invention relates to the field of building formwork technology, specifically to building formwork hoisting and positioning devices and their usage methods. Background Technology

[0002] Construction engineering refers to the physical engineering project formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. "Buildings" specifically refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that meet people's needs for production, living, learning, and public activities. Traditionally, beams and columns required a wooden mold to be built before pouring cement, and then the mold was filled with cement. With technological advancements, prefabricated steel molds are increasingly used to construct these molds for beams and columns. Prefabricated modular steel molds, due to their high strength and reusability, are widely used in building beam and column projects.

[0003] In the current technology, when setting up the formwork, the supporting structure required for the formwork is usually erected first, and then the formwork is installed piece by piece by workers at a high position on the supporting structure. This installation method requires workers to work at high positions for a long time, poses greater safety hazards, and has low construction efficiency, which does not meet the requirements of modern prefabricated construction. Summary of the Invention

[0004] The purpose of this invention is to provide a building formwork hoisting and positioning device and a method of using it, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a building formwork hoisting and positioning device includes several formwork components arranged in a rectangular array. Each formwork component includes a formwork body and a flange. The flange is generally rectangular and installed at the bottom of the formwork body. Support mechanisms are provided at the bottom of adjacent formwork components in the same column. The support mechanisms are used to support the formwork components. A limiting mechanism connected to the support mechanism is provided on the flange. The limiting mechanism is used to connect adjacent formwork components in the same column together. A connecting rod is connected between the support mechanisms in the same row. Both ends of the connecting rod are provided with connecting mechanisms. The connecting mechanisms are used to connect several connecting rods together. The connecting mechanisms are connected to a hoisting mechanism, which is used to connect a crane.

[0006] Preferably, the support mechanism includes a support plate, with fixed cylinders installed at both ends of the support plate, the connecting rod passing through the fixed cylinders, and the top of the support plate contacting the bottom of the flange edge.

[0007] Preferably, L-shaped mounting plates are installed at both ends of the top of the connecting rod, and a reinforcing plate connected to the top of the fixed cylinder is installed at the bottom of the mounting plate.

[0008] Preferably, the top of the mounting plate is provided with a limiting block that contacts the inner wall of the mold body, and the limiting block is inclined.

[0009] Preferably, the limiting mechanism includes a screw rod, which is mounted on a support plate. Arc-shaped grooves are provided on both sides of the flange edge. The arc-shaped grooves on two adjacent flange edges in the same column cooperate to form a through hole. The top end of the screw rod passes through the through hole, and a locking nut that presses against the flange edge is threaded onto the top end of the screw rod.

[0010] Preferably, the support plate has a through hole, the bottom end of the screw passes through the through hole, and the bottom end of the screw is threadedly connected to a lower locking nut that contacts the bottom of the support plate.

[0011] Preferably, the connecting mechanism includes an I-beam, with bolts evenly threaded to the top of the I-beam, a support plate located inside the cavity of the I-beam fitted on the bolt, and a limiting nut threaded to the bottom of the bolt and in contact with the bottom of the support plate, the support plate supporting the connecting rod.

[0012] Preferably, the top of the tray is connected to a mounting block, and the top of the mounting block has a limiting groove through which the end of the connecting rod passes.

[0013] Preferably, the hoisting mechanism includes a hoisting frame and a connecting rope. A first hoisting hook is installed at both ends of the bottom of the hoisting frame, and a second hoisting hook is installed at both ends of the top of the I-beam. The connecting rope connects the first hoisting hook and the second hoisting hook.

[0014] Another aspect of the present invention provides a method for using a building formwork hoisting and positioning device, the steps of which are as follows:

[0015] Step 1: Positioning and initial fixing of the mold shell components: Distribute the support mechanism in an array, and then arrange each mold shell component in a rectangular array according to the design requirements on top of the support mechanism, ensuring that the flange edge at the bottom of the mold shell body is placed stably and supported by the support plate of the support mechanism.

[0016] Step 2: Connecting the mold shell assemblies: The top of the screw of the limiting mechanism passes through the through hole on the support plate and the through hole formed by the arc grooves of two adjacent flanges in sequence. Tighten the upper locking nut at the top of the screw to press it against the top of the flange. Then tighten the lower locking nut at the bottom of the screw. Through the cooperation of the upper and lower locking nuts, the adjacent mold shell assemblies are reliably connected and limited to the support plate. Repeat this operation until all adjacent mold shell assemblies in the same column are connected into a whole through the support mechanism and the limiting mechanism.

[0017] Step 3: Install the connecting rod and lifting mechanism: Pass the connecting rod through the fixed cylinders of all the supporting mechanisms in the same row in sequence, and place the I-beam of the connecting mechanism in the predetermined lifting position. Adjust the height of the support plate to securely support the end of the connecting rod. Place the end of the connecting rod into the limiting groove of the mounting block. Connect one end of the connecting rope of the lifting mechanism to the first lifting hook at the bottom of the lifting frame, and the other end to the second lifting hook at the top of the I-beam. Connect the top of the lifting frame to the crane hook via slings.

[0018] Step 4: Under the instructions of the crane operator, slowly start the crane equipment to ensure that the hoisting mechanism is evenly stressed. Smoothly and vertically hoist the rectangular array of mold shell components to the installation position, and then slowly lower it to accurately position the mold shell components.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The mold shell assembly of the present invention can be pre-assembled on the ground or floor. After assembly, the mold shell assembly can be hoisted to the installation position by a hoisting mechanism, which reduces the amount of high-altitude work, reduces construction risks, and improves construction safety.

[0021] 2. The mold shell assembly, connecting rod, support plate, and I-beam of the present invention can form an integral whole, which improves the stability and load-bearing capacity of the structure. At the same time, the pre-assembly and overall hoisting of the mold shell assembly make the construction process smoother, reduce the time for on-site assembly and adjustment, and thus improve construction efficiency.

[0022] 3. The mold shell components of this invention are arranged in a rectangular array. They are connected in columns longitudinally by support mechanisms and limiting mechanisms, and in rows laterally by connecting rods. This row-column connection ultimately forms a large spatial grid structure with sufficient rigidity, turning numerous loose mold shell components into a stable hoisting unit, thereby achieving precise and efficient hoisting positioning.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-8 This invention provides a technical solution: a building formwork hoisting and positioning device and its usage method, comprising a plurality of formwork components 1 arranged in a rectangular array. Each formwork component 1 includes a formwork body 101 and a flange 102. The flange 102 is generally rectangular and installed at the bottom of the formwork body 101. Support mechanisms 2 are provided at the bottom of adjacent formwork components 1 in the same column. The support mechanisms 2 are used to support the formwork components 1. A limiting mechanism 5 connected to the support mechanism 2 is provided on the flange 102. The limiting mechanism 5 is used to connect adjacent formwork components 1 in the same column together. A connecting rod 3 is connected between the support mechanisms 2 in the same row. Both ends of the connecting rod 3 are provided with connecting mechanisms 4. The connecting mechanisms 4 are used to connect a plurality of connecting rods 3 together. The connecting mechanisms 4 are connected to a hoisting mechanism 6, which is used to connect a crane.

[0034] The support mechanism 2 includes a support plate 201, with fixed cylinders 204 installed at both ends of the support plate 201. The connecting rod 3 passes through the fixed cylinders 204, and the top of the support plate 201 contacts the bottom of the flange edge 102.

[0035] The top of the support plate 201 can contact the flange edge 102 on two adjacent mold shell bodies 101 to support the two adjacent mold shell bodies 101. Since the mold shell assembly 1 is distributed in a rectangular array, the support plate 201 is also distributed in a rectangular array. By passing the connecting rod 3 through the fixed cylinder 204 located in the same row, the support plates 201 in the same row can be connected together.

[0036] Both ends of the top of the connecting rod 3 are equipped with L-shaped mounting plates 202, and the bottom of the mounting plates 202 is equipped with reinforcing plates 205 that are connected to the top of the fixed cylinder 204.

[0037] When the reinforcing plate 205 is connected to the fixing cylinder 204, a stable main body can be formed between the mounting plate 202, the reinforcing plate 205, the support plate 201 and the fixing cylinder 204. When the connecting rod 3 passes through the fixing cylinder 204 in the same row and is hoisted, the fixing cylinder 204 can ensure the strength and stability of supporting the connecting rod 3.

[0038] The top of the mounting plate 202 is provided with a limiting block 203 that contacts the inner wall of the mold body 101, and the limiting block 203 is inclined.

[0039] The end of the limiting block 203 is inclined. When the support plate 201 supports two adjacent mold shell components 1, the mounting plate 202 and the limiting block 203 can extend into the inner cavity of the mold shell body 101. At the same time, the end of the limiting block 203 can contact the inner side wall of the mold shell body 101 to support the mold shell body 101.

[0040] The limiting mechanism 5 includes a screw 501, which is mounted on the support plate 201. Arc grooves 103 are provided on both sides of the flange edge 102. The arc grooves 103 on two adjacent flange edges 102 in the same column cooperate to form a through hole 104. The top end of the screw 501 passes through the through hole 104, and the top end of the screw 501 is threadedly connected to an upper locking nut 502 that is pressed on the flange edge 102.

[0041] When the upper locking nut 502 is tightened, the upper locking nut 502 will press on the two flange edges 102 so that the two adjacent mold shell assemblies 1 can be limited and connected together. When the mold shell assemblies 1 located in the same column are connected together, the mold shell assemblies 1 are not easy to move or shift.

[0042] The support plate 201 has a through hole 206, the bottom end of the screw 501 passes through the through hole 206, and the bottom end of the screw 501 is threadedly connected to a lower locking nut 503 that contacts the bottom of the support plate 201.

[0043] When the bottom end of the screw 501 passes through the through hole 206 and is threaded to the lower locking nut 503, the lower locking nut 503 cooperates with the upper locking nut 502 to limit and connect the two adjacent mold shell assemblies 1.

[0044] The connecting mechanism 4 includes an I-beam 401, with bolts 402 evenly threaded on the top of the I-beam 401. A support plate 403 located inside the cavity of the I-beam 401 is fitted on the bolts 402. A limiting nut 404 that contacts the bottom of the support plate 403 is threaded on the bottom of the bolts 402. The support plate 403 supports the connecting rod 3.

[0045] The top of the bolt 402 passes through the I-beam 401 and extends into the inner cavity of the I-beam 401. The connecting rod 3 can pass through the fixed cylinder 204 in the same row. Then the end of the connecting rod 3 can be placed on the support plate 403 so that it can be supported by the support plate 403.

[0046] Because the connecting rod 3 passes through the fixed cylinder 204 in the same row and the adjacent mold shell components 1 in the same column can be connected together, the numerous loose mold shell components 1 can be transformed into a stable hoisting unit, thereby achieving precise and efficient hoisting positioning. During hoisting, when the two I-beams 401 are raised and lowered, they can support the parallel connecting rod 3 to rise and fall synchronously, thereby enabling the rectangular array of mold shell components 1 to rise and fall as a whole, improving hoisting efficiency.

[0047] The top of the tray 403 is connected to the mounting block 405, and the top of the mounting block 405 is provided with a limiting groove 406 through which the end of the connecting rod 3 passes.

[0048] When the connecting rod 3 passes through the limiting groove 406, the connecting rod 3 can be supported by the support plate 403 and the mounting block 405. At the same time, the two I-beams 401 cooperate to limit the end of the connecting rod 3, which can restrict the displacement of the connecting rod 3 in its axial direction.

[0049] The top opening of the limiting groove 406 and the bottom inner wall of the limiting groove 406 can be fitted with a strip-shaped guide block, while the bottom of the connecting rod 3 can be provided with a strip-shaped guide groove into which the guide block can be inserted. The cooperation between the guide block and the guide groove can prevent the connecting rod 3 from rotating.

[0050] The hoisting mechanism 6 includes a hoisting frame 601 and a connecting rope 604. The bottom ends of the hoisting frame 601 are equipped with first hoisting hooks 602, and the top ends of the I-beam 401 are equipped with second hoisting hooks 603. The connecting rope 604 connects the first hoisting hooks 602 and the second hoisting hooks 603.

[0051] The top of the lifting frame 601 is connected to the hook of the crane via ropes, while the first lifting hooks 602 on both sides of the bottom of the lifting frame 601 can be connected to the I-beams 401 via connecting ropes 604. When the two I-beams 401 are lifted, the arrayed mold shell components 1 can be lifted as a whole.

[0052] The steps for using building formwork hoisting and positioning devices are as follows:

[0053] Step 1, Positioning and initial fixing of mold shell assembly 1: Distribute the support mechanism 2 in an array, and then arrange each mold shell assembly 1 in a rectangular array according to the design requirements above the support mechanism 2, ensuring that the flange edge 102 at the bottom of the mold shell body 101 is placed stably and supported by the support plate 201 of the support mechanism 2.

[0054] Step 2: Connecting the mold shell assembly 1: The top end of the screw 501 of the limiting mechanism 5 passes through the through hole 206 on the support plate 201 and the through hole 104 formed by the abutment of the arc grooves 103 of two adjacent flange edges 102. Tighten the upper locking nut 502 at the top end of the screw 501 to press it against the top of the flange edge 102. Then tighten the lower locking nut 503 at the bottom end of the screw 501. Through the cooperation of the upper locking nut 502 and the lower locking nut 503, the adjacent mold shell assemblies 1 are reliably connected and limited to the support plate 201. Repeat this operation until all adjacent mold shell assemblies 1 in the same column are connected into a whole through the support mechanism 2 and the limiting mechanism 5.

[0055] Step 3: Install connecting rod 3 and lifting mechanism 6: Pass connecting rod 3 sequentially through the fixing cylinders 204 of all support mechanisms 2 in the same row, and place the I-beam 401 of connecting mechanism 4 in the predetermined lifting position. Adjust the height of the support plate 403 so that it can stably support the end of connecting rod 3. Place the end of connecting rod 3 into the limiting groove 406 of the mounting block 405, connect one end of the connecting rope 604 of lifting mechanism 6 to the first lifting hook 602 at the bottom of lifting frame 601, and the other end to the second lifting hook 603 at the top of I-beam 401. The top of lifting frame 601 is connected to the hook of crane via slings.

[0056] Step 4: Under the instructions of the crane operator, slowly start the crane equipment to ensure that the hoisting mechanism 6 is evenly stressed. Smoothly and vertically hoist the rectangular array of mold shell components 1 to the installation position, and then slowly lower it to accurately position the mold shell components 1.
