The utility model discloses can realize not moving fire and not destroying under the condition of primary structure and whole outward appearance, improve timber roof truss shear strength and last string compressive strength, and the construction is simpler.
Description
Technical Field
The utility model relates to a house reinforcement technical field especially relates to a wood roof truss tip node reinforced structure.
Background
Most of the buildings with wood structures exist in the last century, and the stability and the service life of the buildings gradually do not meet the requirements. For part of the brick-wood structure buildings with important significance and use value, the reinforcement construction can be completed only in a limited space for better preserving the original buildings under the condition of not damaging the original structures. The existing reinforcement construction method also has the following defects:
1. the roof needs to be lifted to reinforce the roof truss, and the appearance of the original structure is damaged.
2. The construction process may have the place that needs the fire, has destroyed the original structure of building, can cause the potential safety hazard even.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a wood roof truss tip node reinforced structure, including placing the wedge in wood roof truss triangle space, install the splint in wood roof truss both sides through the fastener, the U type hoop board that sets up between per two fasteners to and the installation is fixed and is being sealed the steel sheet at the node tip.
Furthermore, a structural adhesive layer is arranged at a gap between the wood roof truss and the wedge-shaped block.
Further, the fastener is a bolt, or a screw, or a rivet.
Furthermore, a structural adhesive layer is arranged between the U-shaped hoop plate and the clamping plate.
Furthermore, the wedge-shaped block is formed by mutually bonding a plurality of wedge-shaped block units through structural adhesive.
The utility model has the advantages that:
1. compared with the prior art, the utility model does not need to lift the roof and then reinforce the roof truss, thus not damaging the appearance of the original structure;
2. compared with the prior art, the utility model has the advantages that fire is not needed in the construction process, the structural adhesive is used for connecting the components, and the original structure is not damaged;
3. wedge blocks are arranged in the triangular space of the existing wood roof truss for supporting, so that the upper chord compression strength of the wood roof truss can be improved;
4. the clamping plates are fixedly arranged outside the existing wood roof truss and fixed through the U-shaped hoop plates, so that the shear strength of the wood roof truss can be improved, and the wood roof truss is reinforced.
Drawings
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained without inventive work, wherein:
FIG. 1 is a schematic view of the installation of the present invention;
FIG. 2 is a schematic plan view of the present invention;
fig. 3 is an exploded view of the structure of the present invention.
Detailed Description
The technical solution of the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. For convenience of description, the words "upper", "lower", "left" and "right" in the following description are used only to indicate the correspondence between the upper, lower, left and right directions of the drawings themselves, and do not limit the structure.
As shown in fig. 1-3, the utility model provides a wood roof truss tip node reinforced structure, including placing wedge 4 in wood roof truss 1 triangular space, wedge 4 passes through the structure by the polylith wedge unit and glues each other and form, glues each other between the polylith wedge unit and forms certain thickness, and its thickness is the same with the thickness of the chord member of wood roof truss 1, installs the splint 2 in wood roof truss 1 both sides through fastener 6, the U type hoop 5 that sets up between per two fasteners 6 to and the installation is fixed and is being sealed steel sheet 3 at the most tip of node.
In this embodiment, a structural adhesive layer is arranged at a gap between the wood roof truss 1 and the wedge-shaped block 4.
The fastening member 6 in this embodiment is a bolt, or a screw, or a rivet. The preferred fastener 6 in this embodiment is a bolt.
In this embodiment, a structural adhesive layer is disposed between the U-shaped hoop plate 5 and the clamping plate 2.
The utility model discloses a work progress as follows: firstly, the clamping plates 2 are fixedly arranged on the wood roof truss 1 at two sides of the wood roof truss 1 by using fasteners 6, and then the encapsulated steel plate 3 is fixedly arranged at the most end part of the node by rivets, so that a closed space with partial opening is formed among the upper chord, the lower chord, the web member and the two clamping plates 2. Then a plurality of wedge-shaped block units with the same thickness as the chord of the wood roof truss 1 are plugged into the closed space to form a wedge-shaped block 4 with a certain thickness, so that the wedge-shaped block 4 supports the upper chord of the wood roof truss 1, and structural adhesive is filled in the gap between the wedge-shaped block 4 and the wood roof truss 1 and the closed space, so that the wedge-shaped block 4 is installed and fixed on the wood roof truss 1 to form a whole. And then sealing the closed space, and finally connecting the U-shaped hoop plates 5 between every two fasteners 6 through structural adhesive, wherein the shear strength of the wood roof truss can be improved through the combined installation of the steel plates, so that the wood roof truss is reinforced.
The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used in the specification and the attached drawings, or directly or indirectly applied to other related technical fields, and the same principle is included in the protection scope of the present invention.
