Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a formwork support device and its construction method for a small space column joint between two structural columns. Background Technology

[0002] Formwork reinforcement is an indispensable step in building construction. During concrete pouring, formwork is installed to restrict the shape of concrete components, and then reinforced with joists, locking devices, and other fasteners to ensure that the formwork does not deform during concrete pouring. Due to various reasons, some concrete columns in buildings are designed with insufficient spacing, making formwork reinforcement difficult and resulting in poor stability within the limited space.

[0003] In existing formwork reinforcement systems, square timber and steel pipes are usually used as the main keel, and bolts are used to tighten the keel to fix the formwork, or square and round buckles are used to reinforce the formwork.

[0004] The two commonly used column reinforcement methods mentioned above require a large amount of space during construction. When the construction space is too small, not only is the operation time-consuming and labor-intensive, but the reinforcement effect is also poor, often causing problems such as honeycomb and formwork bulging on the concrete forming surface. On the other hand, when using traditional square timber, steel pipes, and square and round buckles for reinforcement, improper arrangement of the first step at the column base can easily lead to grout leakage. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, a formwork support device and its construction method for a small space column gap between two structural columns are provided to solve the problem of high difficulty in reinforcement operation of existing formwork reinforcement systems in the limited space between two columns.

[0006] To achieve the above objectives, a formwork support device for a small space column gap between two structural columns is provided, comprising a multi-layered unit structure vertically stacked together, wherein the unit structure includes:

[0007] Two sets of edge-locking devices, each set including two positioning components and two connecting rods, two rectangular column molds with two opposing faces, each positioning component including two support members and a guide shaft fitted together, one support member having a limiting flange on its outer side, the limiting flange and the support member forming a positioning through groove, the two corners of the opposing faces of each rectangular column mold in the width direction being embedded in the two positioning through grooves of one set of edge-locking devices, the upper and lower parts of the support members respectively having vertically arranged strip holes, the two support members... The guide shafts are slidably installed in the upper strip hole and the lower strip holes of the two support members respectively. The guide shafts are equipped with locking members for locking the support members. The middle parts of the two connecting rods are pivotally connected together by a hinge shaft. The ends of the two connecting rods are respectively hinged to the two guide shafts of a positioning assembly. The two support members are staggered. The bottom surface of one support member and the lower part of the other support member form a socket notch. The upper part of one support member extends above the top surface of the other support member and is inserted into the socket notch of the upper unit structure.

[0008] Multiple adjustable-length top support components, which are supported between another support member of the positioning components corresponding to the positions of the two sets of locking seams.

[0009] Furthermore, one end of the guide shaft is connected to a first pressing member, which fits against the outer side of the support member, and the other end of the guide shaft is arbitrarily mounted with a second pressing member, which presses against the outer side of the other support member.

[0010] Furthermore, one end of the connecting rod has a through hole, and the other end of the guide shaft is rotatably inserted into the through hole.

[0011] Furthermore, one end of the connecting rod is placed between the other support plate and the second pressing member.

[0012] Furthermore, a handle is connected to the other end of the guide shaft, and the handle is set at an angle to the guide shaft.

[0013] Furthermore, the support assembly includes:

[0014] A fixed sleeve, one end of which is fixed to the outside of another support plate of a set of locking devices, and the other end of which is formed with an internal thread;

[0015] The screw is screwed to the other end of the fixed sleeve and supported on the outside of another support plate of another set of locking devices.

[0016] Furthermore, a limiting groove is formed on the outer side of the other support plate of the other set of locking devices, and the end of the screw is detachably inserted into the limiting groove.

[0017] This invention provides a construction method for a formwork support device for a small space column joint between two structural columns, comprising the following steps:

[0018] Two rectangular column molds are erected opposite each other, so that a small space column gap is formed between the two opposite faces of the two rectangular column molds;

[0019] The number of layers in the unit structure is determined based on the height of the rectangular column mold;

[0020] Based on the width of the rectangular column mold, the position of the guide shaft of the edge-locking device in the strip hole of the two support members is adjusted to adjust the cross angle of the two connecting rods of the edge-locking device, so that the distance between the two positioning through slots of the edge-locking device is adapted to the distance between the two corners in the width direction of the opposite face of the rectangular column mold;

[0021] Multiple unit structures are installed from bottom to top within the small space column joint. When installing the unit structure, one layer of unit structure is placed in the small space column joint, and then the top support component is extended so that the two corners of the two rectangular column molds are respectively embedded in the two positioning through slots of the two sets of locking devices of the first layer unit structure. When installing the upper unit structure, the upper part of a support member of the lower unit structure is inserted into the socket notch of the upper unit structure to vertically stack the multiple unit structures together.

[0022] The beneficial effects of this invention are as follows: The formwork support device for the small space column joint between two structural columns utilizes the positioning components of the locking devices to tightly clamp the corners of the rectangular column molds, ensuring that the rectangular column molds do not shift during concrete pouring. The extension of the top support components locks the two locking devices, thereby supporting the rectangular column molds between the two rectangular column molds and providing sufficient support force to prevent mold bulging and bursting. Furthermore, the formwork support device for the small space column joint between two structural columns uses a multi-layer unit structure with vertical overlapping and interlocking to adapt to structural columns of different heights and specifications. This achieves three-dimensional adjustability in three directions: the width of the structural column, the distance between the two structural columns, and the height of the structural column. This makes the formwork support within the small space column joint convenient, time-saving, labor-saving, and stable. Attached Figure Description

[0035] There are two support members 11. The two support members are fitted together. In this embodiment, the support members are plate-shaped or sheet-shaped.

[0036] A limiting flange 111 is formed on the outer side of a support member 11. The limiting flange 111 and the support member 11 enclose a positioning through groove. The openings of the two positioning through grooves of each locking device are arranged opposite to each other. After installation, the two corners in the width direction of the opposite face of each rectangular column mold 3 are embedded in the two positioning through grooves of a set of locking devices 1.

[0037] Each support member 11 has a strip-shaped hole at its upper and lower parts. The strip-shaped holes are arranged vertically. In this embodiment, the strip-shaped holes are arranged along the length of the support member.

[0038] Guide shafts 12 are slidably installed in the upper and lower slots of the two support members 11, respectively.

[0039] A guide shaft 12 is slidably disposed in the upper slot of the two support members 11. A guide shaft 12 is slidably disposed in the lower slot of the two support members 11.

[0040] The guide shaft 12 is equipped with a locking element. The locking element is used to lock the support element 11.

[0041] The two connecting rods 16 are pivotally connected at their midpoints via a hinge shaft. The ends of the two connecting rods 16 on the same side are respectively hinged to two guide shafts 12 at the upper and lower parts of a positioning assembly.

[0042] In this embodiment, the two support members 11 are staggered. The bottom surface of one support member 11 and the lower side surface of the other support member 11 form a socket notch. The upper part of one support member 11 extends above the top surface of the other support member 11, and during installation, the upper part of one support member 11 is inserted into the socket notch of the upper unit structure A.

[0043] There are multiple top support components 2. The length of the top support component 2 is adjustable. The top support component 2 is supported between another support member 11 of the positioning component corresponding to the positions of the two sets of locking devices 1.

[0045] In a preferred embodiment, the top support assembly 2 includes a fixing sleeve 21 and a screw 22.

[0046] Specifically, one end of the fixing sleeve 21 is fixed to the outside of another support plate of a set of locking devices 1. The other end of the fixing sleeve 21 has an internal thread. The screw 22 is screwed into the other end of the fixing sleeve 21. The screw 22 is supported on the outside of another support plate of another set of locking devices 1.

[0047] In a preferred embodiment, a limiting groove is formed on the outer side of another support plate of another set of locking devices 1. The end of the screw 22 is detachably inserted into the limiting groove.

[0048] See Figure 3 As shown, one end of the guide shaft 12 is connected to a first pressing member 13. The first pressing member 13 fits against the outer side of a support member 11. The other end of the guide shaft 12 is adjustablely mounted with a second pressing member 14. The second pressing member 14 presses against the outer side of another support member 11.

[0050] In a preferred embodiment, one end of the connecting rod 16 is placed between another support plate and the second pressing member 14.

[0051] In this embodiment, the second pressing member is a nut. The other end of the guide shaft 12 is connected to a handle 15. The handle 15 is set at an angle to the guide shaft 12. During construction, by fixing the second pressing member, the guide shaft is rotated by the handle, thereby causing the second pressing member to press against the outside of another support member 11 to lock the position of the guide shaft in the slot.

[0052] The formwork support device for the small space column joint between two structural columns of the present invention utilizes the positioning components of the locking devices to tightly clamp the corners of the rectangular column formwork, ensuring that the rectangular column formwork does not shift during concrete pouring. The extension of the top support component locks the two locking devices, thereby supporting the rectangular column formwork between the two rectangular column formworks and providing sufficient support force to prevent formwork bulging and bursting. The formwork support device for the small space column joint between two structural columns of the present invention uses a multi-layer unit structure with vertical overlapping and interlocking to adapt to structural columns of different heights and specifications. It achieves three-dimensional adjustability in three directions: the width of the structural column, the distance between the two structural columns, and the height of the structural column, making the formwork support within the small space column joint both convenient and stable.

[0057] S4. Install the multi-layer unit structure A from bottom to top in the small space column joint. When installing the unit structure A, set one layer of unit structure A in the small space column joint, and then extend the top support component 2 so that the two corners of the two rectangular column molds 3 are respectively embedded in the two positioning through slots of the two sets of locking devices 1 of the first layer of unit structure A. When installing the upper unit structure A, insert the upper part of a support member 11 of the lower unit structure A into the socket notch of the upper unit structure A so as to vertically stack the multi-layer unit structures A together.
