Description

Technical Field

[0001] This invention relates to the field of formwork reinforcement structure technology, and in particular to a convenient and quick-to-use building formwork reinforcement system and its construction method. Background Technology

[0002] Currently, in building structure construction, steel formwork, which requires numerous tower crane trips, has gradually withdrawn from the mainstream structural construction market. It has been replaced by modular, piecemeal construction of wall panels and roof slabs, which has improved construction speed to some extent. Existing building formwork reinforcement systems consist of secondary and primary joists. The primary joists are of the same specification and are connected by connectors. Internal corner connectors are used at the inside corners of adjacent wall sections, while external corner connectors are used at the outside corners. This is particularly problematic for small wall piers, L-shaped walls, Z-shaped walls, and convex walls, where construction is inconvenient. Crossbeams, being single-function, cannot be universally used as primary joists, and there are many different types and types of accessories, making construction cumbersome. Summary of the Invention

[0003] The purpose of this invention is to provide a convenient and quick-to-use building formwork reinforcement system structure, solving the problems of inconvenient installation of horizontal joists at internal and external corners in existing formwork reinforcement systems, especially for small-sized wall piers, L-shaped walls, Z-shaped walls, and convex walls, where construction is difficult; the crossbeams have a single function and cannot be used as general-purpose main joists; and there are many accessories, making installation time-consuming and labor-intensive. Another purpose of this invention is to provide a convenient and quick construction method for the building formwork reinforcement system structure.

[0004] To achieve the above objectives, this invention provides a convenient and quick-to-use building formwork reinforcement system, including horizontal keels and vertical keels. The vertical keels are steel-wood keels connected to the formwork. The horizontal keels are perpendicular to the vertical keels and are fixed to the formwork by through-wall bolts. The horizontal keels include horizontal keel one and horizontal keel two. One end of horizontal keel one is inserted into horizontal keel two and crosses to form an outer angle and an inner angle. The outer angle locks the vertical keel at the inside corner of the wall formwork. The inner angle presses down on the vertical keels on both sides of the outside corner of the wall formwork. Horizontal keel two and horizontal keel one are locked together by inserts to secure the vertical keels at the inside and outside corners. The combination of horizontal keel one and horizontal keel two is flexible and applicable to the outside corners, inside corners, wall tops, wall piers, inside corners with columns, outside corners with columns, convex structures, and square columns of wall formwork.

[0005] The second transverse keel includes an upper plate and a lower plate arranged in parallel. Both the upper plate and the lower plate are provided with staggered double rows of holes for inserting the insert. A connecting plate is provided between the two ends of the upper plate and the lower plate. The distance between the connecting plate and the end of the upper plate and the lower plate near the connecting plate is 30-40mm.

[0006] The second horizontal keel is connected to the through-wall bolt via a gasket. The through-wall bolt is located between the upper and lower plates, and the two ends of the through-wall bolt are locked to the second horizontal keel via inserts.

[0007] Several bolt connection holes are provided on the surface of the second horizontal keel and / or the first horizontal keel, which has staggered double rows of holes.

[0008] Preferably, the first transverse keel includes an upper plate and a lower plate arranged in parallel, and both the upper plate and the lower plate are provided with staggered double rows of holes for inserting the insert. The two ends of the upper plate and the lower plate are connected by a connecting plate. The distance between the upper plate and the lower plate of the second transverse keel is at least 3mm greater than the height of the first transverse keel.

[0009] Preferably, the first transverse keel is a double-row perforated rectangular steel pipe keel, and the height of the first transverse keel is less than the distance between the upper and lower plates of the second transverse keel.

[0010] Preferably, the length of the limiting hole of the staggered double row of holes on the first and second transverse keels is 38mm.

[0011] Preferably, when the length of the first and second horizontal keels is 600mm, a connecting plate is provided at each end of the first and second horizontal keels; when the length of the first and second horizontal keels is 900mm, three connecting plates are evenly arranged between the first and second horizontal keels; when the length of the first and second horizontal keels is 1200mm, four connecting plates are evenly arranged between the first and second horizontal keels.

[0012] Preferably, adjacent transverse keels one and two located on the same straight line are connected by I-shaped connectors.

[0013] Preferably, the I-shaped connector includes an upper connecting plate and a lower connecting plate arranged in parallel, a second connecting plate is provided between the middle of the upper connecting plate and the lower connecting plate, and both ends of the upper connecting plate and the lower connecting plate are provided with staggered double-row holes corresponding to the staggered double-row holes on the first or second transverse keel.

[0014] Preferably, the gasket has a “]” structure, including a baffle, with clamping plates at both ends of the baffle, the distance between the two clamping plates being not less than the height of the first and second transverse keels, and a through hole in the middle of the baffle for the wall bolt to pass through.

[0015] The above-mentioned construction method for a convenient and quick building formwork reinforcement system includes the following steps:

[0016] 1) Determining the dimensions: Determine the wall dimensions and design the scheme based on the construction drawings, and calculate the specifications, models, and quantities of horizontal and vertical keels, as well as the location and quantity of through-wall bolt holes, etc.

[0017] 2) Vertical keel assembly: Place several vertical keels in sequence at fixed intervals and fix them to the template with nails to obtain the assembled template. Stand the template up and drill holes in the template at the designed intervals.

[0018] 3) Install through-wall bolts: Insert sleeves and through-wall bolts through the holes drilled in the formwork;

[0019] 4) Install horizontal keel two: Install horizontal keel two on the through-wall bolt. The through-wall bolt passes between the upper and lower plates of horizontal keel two. Put a gasket on the through-wall bolt. The clip of the gasket is locked on the upper and lower plates. Select the appropriate hole on the through-wall bolt and insert the insert at both ends of the through-wall bolt to fix the horizontal keel two on both sides of the template.

[0020] 5) Install horizontal keel one: Insert one end of horizontal keel one between the upper and lower plates of horizontal keel two. Pass the through-wall bolt through the fixing hole of horizontal keel one. Select the appropriate limiting holes on horizontal keel one and horizontal keel two and insert the inserts. Tighten horizontal keel one and horizontal keel two against the vertical keel at the inside corner and outside corner.

Select appropriate holes on the through-wall bolt and insert inserts at both ends of the through-wall bolt to fix the horizontal keel one on both sides of the template.

[0022] The first and second horizontal keels, which are located on the same straight line, are connected by connectors.

[0023] 6) Install the wall end crossbeams, which consist of horizontal keel one and horizontal keel two. Horizontal keel one is inserted between the upper and lower plates of horizontal keel two, and horizontal keel one is clamped to the vertical keel of the wall end by inserts. Horizontal keel two is sleeved on the outside of horizontal keel one, and horizontal keel one is pressed against the connecting plate one at one end of horizontal keel two, and horizontal keel one is clamped to the vertical keel of the wall end by inserts.

[0024] 7) Mold alignment: Adjust the verticality and geometric dimensions of the template, and tighten the inserts.

[0042] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

Figure 2 This is a schematic diagram of the external corner structure in Embodiment 1 of the present invention, which describes a convenient and quick-to-use building formwork reinforcement system and its construction method.

Figure 9 This is a schematic diagram of a gasket structure in an embodiment of a convenient and quick-to-use building formwork reinforcement system and its construction method according to the present invention. Figure 10This is a schematic diagram of the I-beam connector structure of an embodiment of a convenient and quick-to-use building formwork reinforcement system and its construction method according to the present invention. As shown in the figure, a convenient and quick-to-use building formwork reinforcement system includes horizontal keels and vertical keels 2. The vertical keels 2 are steel-wood keels connected to the formwork 1. The steel-wood keel is an existing structure. The horizontal keels are perpendicular to the vertical keels 2 and are connected to the formwork 1 by through-wall bolts 6. The through-wall bolts 6 adopt the through-wall bolt 6 structure from a Chinese invention patent for a building formwork 1 reinforcement system and its construction method. The horizontal keels include a vertically arranged horizontal keel 1 3 and a horizontal keel 2 4. One end of the horizontal keel 1 3 is located inside the horizontal keel 2 4 and is inserted into it. One end of the horizontal keel 1 3 is inserted into the horizontal keel 2 4 and intersects to form an outer angle and an inner angle. The outer angle is the shorter angle, and the inner angle is the longer angle. The outer angle is engaged with the vertical keel 2 at the inside corner of the wall formwork. The inner corner presses down on the vertical keel 2 on both sides of the external corner of the wall template. The horizontal keel 2 4 and the horizontal keel 1 3 are locked together by inserts 5 to the vertical keel 2 at the internal and external corners.

[0045] The second horizontal keel 4 includes an upper plate 9 and a lower plate 10 arranged in parallel. Both the upper plate 9 and the lower plate 10 have corresponding limiting holes 11 for inserting the insert piece 5; these limiting holes are arranged in a staggered double row. The upper plate 9 and the lower plate 10 of the second horizontal keel are made of 6mm thick flat steel. The two ends of the upper plate 9 and the lower plate 10 are connected by a connecting plate 12, which is welded to both ends of the upper plate 9 and the lower plate 10. The distance between the connecting plate 12 at both ends of the second horizontal keel 4 and the end is 30-40mm. This arrangement is intended to: form an outer angle when the first horizontal keel 3 is inserted into the second horizontal keel 4; and press the first horizontal keel 3 against the connecting plate 12 of the second horizontal keel 4. This eliminates the need for the insert piece 5 on the second horizontal keel 4, reducing costs and facilitating construction. The extension of the connecting plate 12 at the end of the second horizontal keel 4 is for fixing the vertical keel 2 at the internal corner. The length of the limiting holes 11 in the staggered double rows of holes on the second transverse keel 4 is 38mm. The distance between adjacent limiting holes 11 in the same row is set as needed. In this embodiment, the distance between adjacent limiting holes 11 is 14mm. Limiting holes 11 may not be provided in the middle of the second transverse keel 4, or the spacing of the limiting holes 11 in the middle may be larger, which is beneficial to reducing processing costs and improving the strength of the second transverse keel 4.

[0046] The first transverse keel 3 includes an upper plate 9 and a lower plate 10 arranged in parallel. Both the upper plate 9 and the lower plate 10 have staggered double rows of holes for inserting the insert piece 5. The two ends of the upper plate 9 and the lower plate 10 are connected by a connecting plate 12. In this embodiment, the structure of the first transverse keel 3 is exactly the same as that of the second transverse keel 4, except that the height of the first transverse keel 3 is less than the distance between the upper plate 9 and the lower plate 10 of the second transverse keel 4.

[0047] Horizontal keel 2 4 and horizontal keel 1 3 are connected to the through-wall bolt 6 via gasket 8. The through-wall bolt 6 is located between the upper plate 9 and the lower plate 10. Both ends of the through-wall bolt 6 are locked to the horizontal keel 2 4 via inserts 5. The inserts 5 are existing wedge-shaped inserts 5 structures. The gasket 8 has a "]" structure. The gasket 8 includes a baffle 14, and the two ends of the baffle 14 are provided with retaining plates 15. The distance between the two retaining plates 15 is not less than the height of the horizontal keel 2 4. The retaining plates 15 are engaged with the horizontal keel 2 4 and the horizontal keel 1 3. The middle of the baffle 14 is provided with a connecting hole 16 for the through-wall bolt 6 to pass through. The through-wall bolt 6 is connected to the horizontal keel 2 4 via the gasket 8, improving the stability of the connection.

[0048] The wall tops of template 1 are locked in place by horizontal keel 1 (3) and horizontal keel 2 (4), meaning that horizontal keel 1 (3) and horizontal keel 2 (4) are used as crossbeams, reducing the number of accessories. Inserts 5 are inserted into the limiting holes 11 on horizontal keel 1 (3) and horizontal keel 2 (4) to clamp and fix the horizontal keel 1 (3) and horizontal keel 2 (4) to the vertical keel 2 at the wall top. This solves the problem that crossbeams cannot be used universally as main keels.

[0049] When the second horizontal keel 4 is used as a crossbeam, the first horizontal keel 3 on one side of the template 1 rests against the connecting plate 12. The distance between the upper plate 9 and the lower plate 10 of the second horizontal keel 4 is not less than 58mm, so that the first horizontal keel 3 can be inserted into the second horizontal keel 4 and the weld at the connecting plate 12 can be avoided from interfering with the first horizontal keel 3.

[0050] When the length of the second transverse keel 4 is no more than 600mm, a connecting plate 12 is provided at each end of the second transverse keel 4. When the length of the second transverse keel 4 is 900mm, in addition to the connecting plate 12 at each end of the second transverse keel 4, a connecting plate 12 is also provided in the middle of the second transverse keel 4. When the length of the second transverse keel 4 is 1200mm, four connecting plates 12 are evenly arranged between the second transverse keels 4. The connecting plates 12 are made of steel plates with a thickness of 6mm.

[0051] For reinforcing the formwork 1 of a small wall pier, a single horizontal keel 3 and a second horizontal keel 4 are sufficient. For reinforcing the formwork 1 of a larger wall, adjacent horizontal keels 3 and 4 on the same straight line are connected by I-shaped connectors 7. The I-shaped connector 7 includes an upper connecting plate 17 and a lower connecting plate 18 arranged in parallel. A second connecting plate 13 is positioned between the middle of the upper connecting plate 17 and the lower connecting plate 18, and the second connecting plate 13 is welded and fixedly connected to the upper connecting plate 17 and the lower connecting plate 18. Both ends of the upper connecting plate 17 and the lower connecting plate 18 have staggered double-row holes corresponding to the staggered double-row holes on the horizontal keel 3 or the second horizontal keel 4. The connector 7 is connected to the horizontal keel 3 or the second horizontal keel 4 via inserts 5.

[0052] The surface of the second horizontal keel 4 and / or the first horizontal keel 3, which has staggered double rows of holes, has several bolt connection holes 20. The first horizontal keel 3 or the second horizontal keel 4 can be used as vertical reinforcement of the horizontal keel. The first horizontal keel 3 or the second horizontal keel 4 used for vertical reinforcement is connected to the second horizontal keel 4 by bolts and "]"-shaped washers 8. The first horizontal keel 3 or the second horizontal keel 4 used for vertical reinforcement is connected to the diagonal brace 19 by bolts.

[0053] The above-mentioned convenient construction method for reinforcing the building structure using formwork 1 includes the following steps:

[0054] 1) Determining the dimensions: Determine the wall dimensions and design the scheme based on the construction drawings, and calculate the specifications, models, and quantities of horizontal and vertical keels 2, as well as the location and quantity of the through-wall bolts 6, etc.

[0055] 2) Assemble the vertical keel 2: Place several vertical keels 2 in sequence at fixed intervals and fix them to the template 1 with nails to obtain the assembled template 1. Stand the template 1 up and drill holes in the template 1 at the designed intervals.

[0056] 3) Install through-wall bolt 6: Insert the sleeve and through-wall bolt 6 from the hole drilled in the template 1;

[0057] 4) Install horizontal keel 2 4: Install horizontal keel 2 4 on the through-wall bolt 6. The through-wall bolt 6 passes through the upper plate 9 and lower plate 10 on the horizontal keel 2 4. Put the gasket 8 on the through-wall bolt 6. The clamping plate 15 of the gasket 8 is clamped on the upper plate 9 and lower plate 10. Select the appropriate hole on the through-wall bolt 6 and insert the insert 5 at both ends of the through-wall bolt 6 to fix the horizontal keel 2 4 on both sides of the template 1.

[0058] 5) Insert one end of the horizontal keel 1 3 between the upper plate 9 and the lower plate 10 of the horizontal keel 2 4. Pass the wall bolt 6 through the upper plate 9 and the lower plate 10 of the horizontal keel 1 3. Put the gasket 8 on the wall bolt 6. The clamping plate 15 of the gasket 8 is clamped on the upper plate 9 and the lower plate 10 of the horizontal keel 1 3. Select the appropriate limiting hole 11 on the horizontal keel 1 3 and the horizontal keel 2 4 and insert the insert 5. Tighten the horizontal keel 1 3 and the horizontal keel 2 4 against the vertical keel 2 at the inside corner and the outside corner. Select the appropriate hole on the wall bolt 6 and insert the insert 5 at both ends of the wall bolt 6 to fix the horizontal keel 1 3 on both sides of the template 1.

[0059] 6) Install the wall top crossbeams, which consist of horizontal keel 1 3 and horizontal keel 2 4. Horizontal keel 1 3 is inserted between the upper plate 9 and the lower plate 10 of horizontal keel 2 4. The horizontal keel 1 3 is clamped to the vertical keel 2 of the wall top by inserting the insert 5. Horizontal keel 2 4 is sleeved on the outside of horizontal keel 1 3. Horizontal keel 1 3 is pressed against the connecting plate 12 at one end of horizontal keel 2 4. The horizontal keel 1 3 is clamped to the vertical keel 2 of the wall top by inserting the insert 5.

[0060] 7) Mold adjustment: Adjust the verticality and geometric dimensions of template 1, and tighten insert 5.

[0061] Example 2

Figure 4 This is a schematic diagram of the external corner structure of a convenient and quick-to-use building formwork reinforcement system and its construction method according to Embodiment 2 of the present invention. As shown in the figure, the horizontal keel 1 3 is an existing double-row perforated rectangular steel pipe keel, and the height of the horizontal keel 1 3 is less than the distance between the upper plate 9 and the lower plate 10 of the horizontal keel 2 4. The connector 7 uses an existing structure.

[0063] The surfaces of the second horizontal keel 4 and / or the first horizontal keel 3, which have staggered double rows of holes, are provided with several bolt connection holes 20. The first horizontal keel 3 or the second horizontal keel 4 can be used as vertical reinforcement for the horizontal keel. The first horizontal keel 3 or the second horizontal keel 4 used for vertical reinforcement is connected to the second horizontal keel 4 via bolts and flat washers. The first horizontal keel 3 or the second horizontal keel 4 used for vertical reinforcement is connected to the diagonal brace 19 via bolts.
