Description

Technical Field

[0001] This utility model relates to the field of building construction formwork technology, specifically a splicing formwork structure and system for beam-column component joints. Background Technology

[0002] In the field of building structure construction, the splicing of formwork at beam-column joints (internal corners) is a crucial construction step. Currently, the commonly used formwork splicing method is 90-degree right-angle splicing. However, during concrete pouring, the internal corner joints of traditional right-angle splicing are prone to bulging due to the lateral pressure of the concrete. Once bulging occurs, the right-angle formwork will get stuck at the beam-column intersection, making demolding difficult and damaging the edges and corners of the formwork. This not only affects the reuse of the formwork but also increases construction costs. In addition, grout leakage is prone to occur at right-angle splices, requiring manual repairs and affecting the appearance quality of the structure. Therefore, there is an urgent need for a new type of splicing formwork structure that can reduce the risk of bulging and is easy to dismantle. Utility Model Content

[0003] The purpose of this invention is to provide a splicing template structure and system for beam-column component joints to solve the problems of easy bulging and difficult removal of templates in traditional right-angle splicing.

[0004] This utility model is implemented as follows:

[0005] A splicing formwork structure for beam-column member joints, comprising:

[0006] Angle template, wherein the two ends of the angle template are provided with first inclined surfaces, and the angle template is used to be installed at the joint of beam-column members;

[0007] A first template, one end of which is provided with a second inclined surface, the second inclined surface being fixedly connected to one end of the included angle template, and the side of the first template being coplanar with the first inclined surface on the same side;

[0008] The second template is perpendicular to the first template. One end of the second template is provided with a third inclined surface. The third inclined surface is fixedly connected to the other end of the included angle template, and the side of the second template is coplanar with the first inclined surface on the same side.

[0009] As a further technical solution, the angle between the first inclined surface and the side of the included template away from the beam-column member node is 45 degrees.

[0010] A splicing formwork system for beam-column member nodes includes eight splicing formwork structures arranged in a surrounding manner, with the ends of two adjacent first formworks in perpendicular contact away from the included angle formwork, and a gap forming a cast structural beam between two adjacent second formworks; the eight splicing formwork structures are connected by locking components.

[0011] As a further technical solution, the locking assembly comprises:

[0012] The timber consists of multiple sets that abut against the outer surfaces of the first template and the second template, with each set consisting of multiple timbers arranged in an array.

[0013] Fasteners, of which there are multiple fasteners, are used to lock two sets of timbers that are arranged opposite to each other.

[0014] As a further technical solution, the fastener includes:

[0015] The steel pipes are arranged in multiple groups along the length of the timber, with two steel pipes arranged in parallel in each group. The axial direction of each steel pipe is the same as the arrangement direction of the timber in each group. The sidewall of the steel pipe abuts against the side of the timber away from the first template or the second template.

[0016] Tie bolts, each group of steel pipes corresponds to multiple tie bolts, the tie bolts are inserted on two oppositely arranged first templates or two oppositely arranged second templates, and both ends are locked to the side wall of each group of steel pipes.

[0017] The beneficial effects of this utility model are:

[0018] 1. Improved resistance to formwork bulging: Angled splicing disperses the lateral pressure of concrete, reduces the probability of formwork bulging at internal corners, and improves the quality of structural construction.

[0019] 2. Reduced template waste: The beveled design facilitates smooth demolding, reduces damage to template edges and corners, and allows template scraps to be used to make angled templates, improving material utilization and reducing costs.

[0020] 3. No grout leakage at the joints: The angled template, the first template and the second template are joined by a bevel, which effectively avoids the problem of grout leakage at the joints.

[0021] 4. Improved construction efficiency: The splicing method is simple, the locking component structure is reliable, and it is easy to install and dismantle quickly, thus speeding up the construction progress. Attached Figure Description

[0027] like Figures 1-3 As shown, this utility model provides a splicing template structure for beam-column component joints, including an angle template 1, a first template 3, and a second template 5.

[0028] Both ends of the angle template 1 are provided with a first inclined surface 2, which is used to set at the node of the beam-column component. The angle between the first inclined surface 2 and the side of the angle template 1 away from the node of the beam-column component is 45 degrees. After pouring, the angle template 1 and the pouring surface of the structural beam 8 and the structural column 9 form an armpit angle with a cross-section of an isosceles right triangle, and the right-angled side of the isosceles triangle is about 2cm long.

[0029] The first template 3 has a second inclined surface 4 at one end. The second inclined surface 4 is fixedly connected to one end of the angle template 1 by screws. The side of the first template 3 is coplanar with the first inclined surface 2 on the same side, forming a casting surface of the structural column 9. The angle between the second inclined surface 4 and the side of the first template 3 away from the structural column 9 is 45 degrees.

[0030] The second template 5 is perpendicular to the first template 3. One end of the second template 5 is provided with a third inclined surface 6. The third inclined surface 6 is fixedly connected to the other end of the included angle template 1 by screws. The side of the second template 5 is coplanar with the first inclined surface 2 on the same side, forming a casting surface of the structural beam 8. The included angle between the third inclined surface 6 and the side of the second template 5 away from the structural beam 8 is 45 degrees.

[0031] The design of this utility model's splicing template structure involves the angled template 1 resting against the side of the concrete beam and column to be poured via the first inclined surface 2 at both ends (45 degrees). The first template 3 and the second template 5 are perfectly fitted onto the angled template 1 via the second inclined surface 4 and the third inclined surface 6 at one end, and are respectively fixed with screws. This changes the joint of the beam and column components from a right angle to an oblique angle, which helps to disperse the lateral pressure of the concrete, reduces the risk of formwork bulging, and the oblique angle splicing facilitates demolding and protects the edges and corners of the template. After the template is spliced, concrete is poured to form the oblique shape of the beam and column component joint. After demolding, plastering and leveling operations can be performed to extend the pouring surface of the structural beam 8 and structural column 9 outward by a certain thickness, so that the beam-column intersection remains a 90-degree right angle, meeting the architectural appearance requirements.

[0032] This utility model also proposes a splicing template system for beam-column component nodes, including 8 splicing template structures arranged around each other, with the ends of two adjacent first templates 3 in perpendicular contact away from the included angle template 1, and a gap forming between two adjacent second templates 5 for casting structural beams 8, and the 8 splicing template structures are connected by locking components 7.

[0033] The locking assembly 7 includes timber 71 and fasteners. The timber 71 consists of multiple sets that abut against the outer surfaces of the first template 3 and the second template 5. Each set consists of multiple sets arranged to evenly transmit the tightening force. The length of each set of timber 71 extends along the length of the beam or column structure. Multiple fasteners are used to lock the two opposing sets of timber 71. Specifically, the fasteners include steel pipes 72 and tie bolts 73. The steel pipes 72 consist of multiple sets arranged along the length of the timber 71. Each set consists of two parallel sets. The axial direction of each steel pipe 72 is the same as the arrangement direction of each set of timber. The sidewall of the steel pipe 72 abuts against the side of the timber away from the first template 3 or the second template 5. Each set of steel pipes 72 corresponds to multiple tie bolts 73. The tie bolts 73 pass through the two opposing first templates 3 or the two opposing second templates 5, and are locked at both ends to the sidewall of each set of steel pipes 72.

[0034] During operation, the splicing formwork system is first cut into angled formwork 1, first formwork 3, and second formwork 5. Angled formwork 1 is placed against the side of the concrete beam / column to be poured via the first inclined surfaces 2 at both ends. First formwork 3 and second formwork 5 are perfectly fitted onto angled formwork 1 via the second inclined surfaces 4 and 6 at one end, and fixed with screws, changing the joint of the beam / column components from a right angle to an oblique angle. Then, timber 71 is evenly arranged on the outside of first formwork 3 and second formwork 5 to form an auxiliary support layer. Steel pipes 72 are installed along the length of the timber 71, arranged in pairs in each group, abutting against the outside of the timber 71. Tie bolts 73 pass through the structural beams 8 and columns, and are inserted into the corresponding first formwork 3 or second formwork 5. Both ends are locked to the sidewalls of the steel pipes 72 with nuts. Each group of steel pipes 72 corresponds to multiple tie bolts 73. One to two more tie bolts 73 are added during reinforcement to ensure stability at the splice. Concrete is then poured. After the concrete is poured, due to the oblique splicing structure, the formwork is easily removed and less prone to damage. After demolding, plastering and leveling operations can be performed to extend the pouring surface of structural beam 8 and structural column 9 outward by a certain thickness, so that the intersection of beam and column remains a 90-degree right angle, meeting the requirements of building appearance.
