Description

Technical Field

[0001] The present invention relates to the field of building construction, and in particular to an attached operating frame applied to a formwork support system and a use method thereof. Background Art

[0002] Cast-in-place buildings are buildings that are supported by a formwork support system and have concrete load-bearing walls poured on-site using an industrialized method. They are suitable for residences and hotels with a large number of interior walls. The aluminum alloy formwork system consists of a formwork system, a support system, a fastening system, and an accessory system. The formwork system constitutes the closed surface required for concrete structure construction, ensuring that the building structure is formed when concrete is poured. The accessory system is the connecting component of the formwork, which connects individual formwork pieces into a system to form a whole. The support system plays a supporting role during the concrete structure construction process, ensuring the floor height, beam bottom and cantilever structure support. The fastening system ensures the structural width size (pin piece) of the formwork to reduce deformation during the concrete pouring process, and the formwork rarely experiences formwork expansion or bursting.

[0003] During the construction process, the formwork support system requires the cooperation of an operating frame to complete the formwork support and dismantling work. However, the traditional operating frame needs to occupy the ground during the erection and use process, which greatly wastes the construction space. The cantilever scaffolding needs to rely on steel beams for erection, and the steel beams need to be firmly fixed at a fixed point, which has high erection requirements.

[0004] Therefore, there is an urgent need for an operating frame to solve the defects of traditional operating frames and cantilever scaffolding. Meeting the needs of formwork support system for supporting and dismantling formwork during construction is a difficult problem for technical personnel in this field. Summary of the Invention

[0005] The present invention aims to solve the above problems and thus provides an attached operating frame and a method of use for a formwork support system, which not only reduces the occupation of ground space on the construction site and improves the utilization rate of the construction site, but also can be attached to the aluminum formwork to ensure the normal progress of construction.

[0006] The present invention solves the above problems by adopting the following technical solutions:

[0007] An attached operation frame applied to a formwork support system, the formwork support system including aluminum formwork, backing ribs and fasteners. Two backing ribs are set as a group on the back side of the aluminum formwork, and the two backing ribs in the group are spaced apart from each other. The fasteners are arranged in the gaps between the two backing ribs of each backing rib group, and the fasteners are arranged at intervals on each backing rib group. The fasteners connect the backing rib group and the aluminum formwork together; the attached operation frame is arranged between adjacent upper and lower backing rib groups. The attached operation frame includes a pedal, vertical columns are vertically arranged on both the left and right sides of the surface of the pedal, and a fence is arranged along the edge of the pedal on one side of the pedal. The fence, the pedal and the two columns jointly enclose a construction part. A plug board parallel to the pedal is jointly connected to the tops of the two columns. The column is a telescopic structure to adjust the distance between the pedal and the plug board. The width of the plug board is the same as that of the other side of the pedal away from the construction part. The plug board and the other side of the pedal away from the construction part are both inserted into the gap of the backing rib group, and the plug board and the other side of the pedal away from the construction part are both located between adjacent fasteners on each backing rib group. At least one connecting piece is installed between adjacent fasteners on each backing rib group. The connecting piece is respectively bolted to the plug board and the pedal, and the plug board, the pedal and the backing rib group are connected together through the connecting piece, so as to fix the attached operation frame on the back side of the aluminum formwork.

[0008] Further, the cross-section of the connecting piece is in a side convex structure, including a left body and a right protruding part. Both backing ribs of the backing rib group are inserted into the left body and are arranged at intervals up and down. The right protruding part is open, and the pedal and the plug board are both inserted into the opening of the right protruding part and inserted between the two backing ribs. The upper and lower plates of the right protruding part are bolted to the pedal or the plug board.

[0009] Further, the fence includes a plurality of vertical rods perpendicular to the surface of the pedal and arranged along the edge of one side of the pedal. The plurality of vertical rods jointly form a U-shaped structure, and a horizontal connecting rod in a U-shaped structure is jointly connected to the tops of the plurality of vertical rods. The two end parts of the horizontal connecting rod are respectively fixedly connected to the columns.

[0010] Further, the plurality of vertical rods and the horizontal connecting rod are both made by assembling hollow rectangular steel pipes.

[0011] Further, connection holes penetrating the plug board are arranged on both the left and right sides of the plug board, and a steel wire rope is bolted to each connection hole. The other ends of the two steel wire ropes are both wound and fixed on the fence.

[0012] Furthermore, the column is a telescopic structure that can be extended up and down, including an upper lattice column and a lower lattice column. The upper end of the upper lattice column is vertically fixed to the bottom surface of the plug plate, and the lower end of the upper lattice column is slidably inserted into the upper end of the lower lattice column. The lower end of the lower lattice column is vertically fixed to the surface of the pedal. A plurality of bolt holes are provided at the connection between the upper lattice column and the lower lattice column. The plurality of bolt holes are arranged in an array, and a high-strength bolt is installed in each bolt hole.

[0013] Furthermore, the lower lattice column is a hollow structure, and a hydraulic support cylinder is provided in the lower lattice column. The telescopic end of the hydraulic support cylinder abuts against the lower end of the upper lattice column, and the lifting of the hydraulic support cylinder drives the lifting of the upper lattice column.

[0014] Furthermore, corrugated protrusions are provided on the surface of the construction part pedal.

[0015] A method for using an attached operating frame applied to a formwork support system comprises the following steps:

[0016] S1. During the construction of the formwork support system, the connectors are pre-installed on the back rib group and set between adjacent fasteners. The number of connectors is determined according to the actual weight carried by the attached operating frame during construction;

[0017] S2. Pre-assemble the attached operating frame on the ground, leaving the high-strength bolts at the connection between the upper and lower lattice columns of each column untightened temporarily to allow the height of the column to be adjusted, thereby allowing the pedal and the insert plate to be smoothly inserted into the gap between the two back ribs of the back rib group;

[0018] S3. The wire rope is not bolted yet to avoid affecting the lifting of the attached operating frame and the subsequent adjustment of the distance between the plug plate and the pedal;

[0019] S4. Lift the attached operating frame to the designated position of the formwork support system, and insert the pedal and insert plate between the connector and the two back ribs;

[0020] S5. When the spacing between the insert plate and the pedal does not match the spacing between two adjacent back rib groups, the hydraulic support cylinder drives the upper lattice column to extend and retract to adjust the height of the column and thus adjust the spacing between the insert plate and the pedal. After the spacing adjustment is completed, the high-strength bolts at the connection between the upper and lower lattice columns are tightened;

[0021] S6. After the pedal and the insert are inserted into the gap between the two back ribs, the connecting piece is bolted to the pedal and the insert respectively to fix the attached operating frame;

[0022] S7. When the attached operating frame is fixed, release the lifting measures and bolt the wire rope between the plug board and the fence to fix it.

[0023] Compared with the prior art, the present invention adopting the above technical solution has the following outstanding features:

[0024] The present invention is based on the formwork support system, and utilizes the space between the aluminum formwork and the back rib group to install the connecting piece of the fixed attached operating frame on the back rib group, and utilizes the space between the two back ribs on the back rib group to insert the plug board and the pedal on the attached operating frame, so that the connecting piece is respectively connected and fixed with the plug board and the pedal bolt, and then the attached operating frame is attached to the back side of the aluminum film plate, which not only reduces the occupation of the ground space on the construction site and improves the utilization rate of the construction site, but also can be attached to the aluminum formwork, ensuring the normal progress of the construction; at the same time, because the spacing between the back rib groups is uncontrollable, the column is set It is a telescopic structure. By adjusting the height of the column, the distance between the plug plate and the pedal is adjusted to ensure that the pedal and the plug plate are smoothly inserted into the gap between the two back ribs of the back rib group, so as to facilitate the smooth installation of the attached operating frame. The attached operating frame can not only be reused, but also can be assembled according to the actual construction space on site. At the same time, the setting of the fence improves safety. Compared with the traditional ground scaffolding, it reduces the occupied ground area, and has lower construction requirements than the cantilever scaffolding. There is no need to find a firm fixed point, which is simpler and more convenient, reducing construction costs while improving on-site construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following description of the embodiments will help the public better understand the present invention, but the specific embodiments given by the applicant cannot and should not be regarded as limitations on the technical solutions of the present invention. Any changes to the definitions of components or technical features and / or formal rather than substantive changes to the overall structure should be regarded as the scope of protection defined by the technical solutions of the present invention.

[0031] See also Figures 1 to 4As shown, the technical solution of the present invention is as follows:

[0032] A type of attached operating frame for a formwork support system, the formwork support system comprising an aluminum formwork 1, back ribs 2, and fasteners 3. The back ribs 2 are arranged in groups of two on the back side of the aluminum formwork 1. The back ribs 2 are made of square steel tubes, and wooden squares are prohibited from being used to prevent safety accidents caused by wooden squares being unable to withstand the attached operating frame and breaking. The two back ribs 2 in a group are spaced apart from each other at the top and bottom. The fasteners 3 are arranged in the gap between the two back ribs 2 in each back rib group. The two back ribs 2 are fixed and attached to the back side of the aluminum film plate by the fasteners 3. The fasteners 3 are spaced apart on each back rib group along the length direction of the back ribs 2. The fasteners 3 connect the back rib groups and the aluminum film plate together.

[0033] The attached operating frame is arranged between two groups of upper and lower adjacent back ribs. The attached operating frame includes a pedal. The pedal is made of 30mm steel plate. Columns are vertically welded on the left and right sides of the pedal surface. Reinforcing ribs are welded at the connection between the column and the pedal to prevent the connection between the column and the pedal from breaking. A fence is welded along the edge of the pedal on the surface of one side of the pedal. The fence, the pedal and the two columns together enclose a construction section 10. The fence protects construction workers entering the construction section 10 to prevent them from falling accidentally. A plug-in plate 9 parallel to the pedal is welded at the top of the two columns. The plug-in plate 9 is made of 50mm steel plate. The tops of the two columns are welded to the lower bottom surface of the plug-in plate 9. Reinforcing ribs are welded at the connection between the column and the plug-in plate 9 to prevent the connection between the column and the plug-in plate 9 from breaking. The column is a telescopic structure and can be adjusted The spacing between the pedal and the plugboard 9 is adjusted so that the plugboard 9 and the pedal can be smoothly inserted into the gap between the two back ribs 2 on the back rib 2 group. The width of the plugboard 9 is consistent with the width of the pedal on the other side away from the construction part 10 to prevent the pedal or the plugboard 9 from being too wide to be inserted into the two back ribs 2 and unable to form an effective and stable connection with the connecting piece 11. The plugboard 9 and the pedal on the other side away from the construction part 10 are both inserted into the gap between the back rib 2 groups. The plugboard 9 and the pedal on the other side away from the construction part 10 are both located between the adjacent fasteners 3 on each back rib 2 group. Two connecting pieces 11 are installed on each back rib 2 group and between the adjacent fasteners 3. The connecting pieces 11 are respectively connected to the plugboard 9 and the pedal bolts. The plugboard 9, the pedal and the back rib 2 groups are connected together through the connecting piece 11, and then the attached operating frame is fixed to the back side of the aluminum formwork 1.

[0034] The cross-section of the connecting member 11 is in a side-mounted convex structure. The connecting member 11 is integrally formed from a 30-mm steel plate and includes a left body and a right protruding part. The left body and the right protruding part are connected together. Two back ribs 2 of the two groups of back ribs are inserted into the left body and are arranged at intervals up and down. The right protruding part is open to facilitate the smooth insertion of the pedal or the insertion plate 9. Both the pedal and the insertion plate 9 are inserted into the opening of the right protruding part and inserted between the two back ribs 2. The upper and lower plate bodies of the right protruding part are bolted to the pedal or the insertion plate 9. The setting of the connecting member 11 forms an effective and stable connection between the insertion plate 9 or the pedal and the two groups of back ribs 2.

[0035] The fence includes a plurality of vertical rods 5 vertically welded to the surface of the pedal and arranged along one edge of the pedal. The number of the vertical rods 5 is determined according to the density during actual construction welding. The plurality of vertical rods 5 together form a U-shaped structure. A horizontal connecting rod 12 in a U-shaped structure is welded together at the tops of the plurality of vertical rods 5. The two end parts of the horizontal connecting rod 12 are respectively welded and fixed to the columns. The fence plays a protective role for the construction workers and at the same time reduces the self-weight of the attached operation scaffold.

[0036] The plurality of vertical rods 5 and the horizontal connecting rod 12 are both assembled from hollow rectangular steel pipes; to reduce the weight of the attached operation scaffold.

[0037] Connecting holes penetrating the insertion plate 9 are provided on both the left and right sides of the insertion plate 9. A steel wire rope 4 is bolted to each connecting hole. The other ends of the two steel wire ropes 4 are both wound and fixed on the fence; the steel wire ropes 4 play a role in pulling the pedal and disperse the weight borne by the pedal.

[0038] The column is an up-and-down telescopic structure and includes an upper lattice column 8 and a lower lattice column 6. The upper end part of the upper lattice column 8 is vertically fixed to the bottom surface of the insertion plate 9. The lower end part of the upper lattice column 8 is slidably inserted into the upper end part of the lower lattice column 6. The lower end part of the lower lattice column 6 is vertically fixed to the surface of the pedal. A plurality of bolt holes are provided at the connection between the upper lattice column 8 and the lower lattice column 6. The plurality of bolt holes are arranged in an array. A high-strength bolt 7 is installed in each bolt hole; the telescoping of the column is achieved through the above structural settings.

[0039] The lower lattice column 6 is a hollow structure. A hydraulic support cylinder 13 is arranged inside the lower lattice column 6. The telescopic end of the hydraulic support cylinder 13 abuts against the lower end part of the upper lattice column 8. The lifting of the upper lattice column 8 is driven by the顶升 of the hydraulic support cylinder 13; the lifting control of the upper lattice column 8 is achieved through the above structural settings.

[0040] Corrugated protrusions are provided on the surface of the pedal of the construction part 10; the protrusions play a role in anti-slip and ensure the safety of construction workers.

[0042] S1. During the construction of the formwork support system, pre-install the connectors 11 on the back ribs 2 and set them between adjacent fasteners 3. The number of connectors 11 is determined according to the actual weight carried by the attached operating frame during construction.

[0043] S2. Pre-assemble the attached operating frame on the ground, wherein the high-strength bolts 7 at the connection between the upper lattice column 8 and the lower lattice column 6 of each column are not tightened temporarily, so as to adjust the height of the column and thus allow the pedal and the insert plate 9 to be smoothly inserted into the gap between the two back ribs 2 of the back rib 2 group;

After the spacing adjustment is completed, the high-strength bolts 7 at the connection between the upper lattice column 8 and the lower lattice column 6 are tightened;

[0047] S6. After the pedal and the insert plate 9 are inserted into the gap between the two back ribs 2, the connecting piece 11 is bolted to the pedal and the insert plate 9 respectively, thereby fixing the attached operating frame;

[0048] S7. When the attached operating frame is fixed, the lifting measures are released, and the steel wire rope 4 between the plug board 9 and the fence is bolted and fixed.
