Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of concrete formwork reinforcement, and particularly relates to a formwork reinforcement device for a connection part of a steel beam and a stiff column. BACKGROUND

[0002] In a traditional mode, the square round buckle or the horizontal main beam combined with the steel pipe and the tensioning screw rod at the connection part of the steel beam and the stiff column is blocked and cut off by the steel beam or the steel column, the reinforcement area at the top of the column cannot form a closed whole, and only the cut wood can be used as the horizontal main beam to temporarily fix the formwork and the secondary beam, and then the wood or the steel pipe and the supporting combination is used to resist the horizontal main beam (wood) on one side and to be supported on the stiffener plate of the protruding web of the steel beam on the other side. This kind of scheme has the following problems:

[0003] 1. Due to the irregular shape of the steel beam, the formwork needs to be cut several times to form a special shape matching the steel beam before the formwork installation, which leads to the decrease of the overall rigidity of the formwork and the increase of the number of joints.

[0004] 2. At the connection joint part of the steel column and the steel beam, the formwork can only be reinforced on the outside of the exposed corner of the steel column, and at the shaded corner part formed by the connection of the steel column and the steel beam, the wooden formwork can only be resisted on the web of the steel beam, and cannot be matched and reinforced at the joint of the steel beam, which leads to the instability of the main beam reinforcement system and the phenomenon of formwork rising or bursting in the pouring process.

[0005] Therefore, the present application provides a formwork reinforcement device for the connection part of the steel beam and the stiff column to solve the above problems. SUMMARY

[0006] In view of the deficiencies in the prior art, the present application provides a formwork reinforcement device for the connection part of the steel beam and the stiff column, which solves the problem of the instability of the main beam reinforcement system and the phenomenon of formwork rising or bursting in the pouring process caused by the fact that the conventional steel beam and the stiff column intersecting part can only use the wood as the simple main beam and cannot form a continuous closed reinforcement system.

[0007] The present application achieves the above technical purpose through the following technical means.

[0008] A formwork reinforcement device for the connection part of the steel beam and the stiff column, comprising eight clamping pieces with the same structure size, eight clamping pieces are connected to form a closed horizontal whole frame, and the formwork of the connection area of the stiff column and the steel beam is reinforced.

[0009] Further, a plurality of mounting holes are opened through the length direction on the surface of the first square steel close to one end, and one mounting hole is opened through the length direction on the other end of the first square steel and the one end of the second square steel.

[0010] Further, the diameter of the mounting hole on the first square steel and the second square steel is 14mm.

[0011] Further, the cross-sectional dimension of the first square steel and the second square steel is 40mm*60mm.

[0012] Further, the length of the first square steel is less than that of the second square steel, and a short square steel is welded and fixed between the other end portions of the two second square steels to block and form a receiving space, and the first square steel is received into the second square steels in rotation under the condition that the nut is not tightened.

[0013] Further, the clamp members are independently arranged on both sides of the web of the steel beam and are fastened on the steel beam through the through-wire screw, nut and gasket, and the first square steels of the adjacent clamp members on both sides of the male corner of the reinforced column are overlapped, and the overlapping portions are fastened through the through-wire screw, nut and gasket.

[0014] Further, the diameter of the through-wire screw is 12mm.

[0015] The present application has the following beneficial effects:

[0016] The template reinforcing device designed in the present application breaks through the mode that the intersection part of the conventional steel beam and the reinforced column can only use a wooden square as a simple main beam and cannot form a continuous closed reinforcing system, especially for the non-orthogonal inclined beam area existing at the top of the large-section reinforced column, the template reinforcing device is more flexible and has a wider application range, can be freely rotated and adjusted after fastening and connecting according to the angle of the inclined beam, and the horizontal reinforcing main beams of the connection part of the top of the reinforced column and the steel beam are connected into a closed whole, the stress is more uniform, the force transmission is more reasonable, and the construction quality and safety are ensured.

DETAILED DESCRIPTION

[0023] The application will be further described below in conjunction with the drawings and specific embodiments, but the scope of protection of the application is not limited thereto.

[0024] As Figure 1 , 3 indicated, the formwork reinforcing device of the steel beam and stiff column connecting part of the application comprises eight clamp pieces 1 which are of the same structure size and independent of each other, and the eight clamp pieces 1 are connected to form a closed horizontal integral frame, thereby surrounding and reinforcing the formwork of the connecting area of the stiff column 4 and the steel beam 2.

[0025] As Figure 1 , 2 indicated, the clamp piece 1 comprises a first square steel 11 with a cross-sectional size of 40mm×60mm, a plurality of installation holes are through-opened on the surface of the first square steel 11 close to one end thereof, and the hole diameter is 14mm, and one installation hole is through-opened on the other end of the first square steel 11; the clamp piece 1 further comprises two second square steels 12 with a cross-sectional size of 40mm×60mm, and one installation hole is through-opened on one end of each of the second square steels 12.

[0026] As Figure 1 , 2 indicated, the end of the first square steel 11 with the installation hole is fixed between the end portions of the two second square steels 12 through the first through-wire screw 13, the first nut 14 and the first gasket 15, thereby connecting the end portions of the three square steels together; when the first nut 14 is tightened, the end portions of the three square steels form a rigid joint and cannot rotate freely, and when the first nut 14 is not tightened, the end portions of the three square steels form a hinged joint and can rotate freely in one direction.

[0027] As Figure 1 , 2As shown, the length of the first square steel 11 is shorter than that of the second square steel 12. A short square steel is welded and fixed between the other ends of the two second square steels 12 to block and form a storage space. When the reinforcement device is not in use, the first nut 14 is not tightened. The first square steel 11 can be rotated and stored between the two second square steels 12 to form a strip-shaped component, which saves more space and facilitates transportation and turnover.

[0028] like Figure 3 , 4 As shown in Figure 5, in actual use, each clamp 1 is independently installed on both sides of the web of the steel beam 2. First, the second threaded rod 31 is passed through the gap between the second square steel 12 on both sides of the web of the steel beam 2 and the hole on the web of the steel beam 2, and then tightened with the second washer 32 and the second nut 33, thereby fastening the clamp 1 to the steel beam 2. Then, the first square steel 11 of the adjacent clamp 1 is overlapped on both sides of the external corner of the stiffening column 4. Specifically, the third threaded rod 51 is passed through the aligned mounting holes on the two first square steel 11 at the overlap position, and then tightened with the third nut 52 and the third washer 53, thereby connecting the eight clamps 1 to form a closed horizontal overall frame, which reinforces the template in the connection area between the stiffening column and the steel beam, effectively improving the stability of the reinforcement system of the stiffening column 4, especially the beam-column joint connection.

[0029] The diameters of the first through screw 13, the second through screw 31, and the third through screw 51 are all 12 mm.

[0030] The embodiments described above are preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Any obvious improvements, substitutions or modifications that can be made by those skilled in the art without departing from the essence of the present invention shall fall within the protection scope of the present invention.
