A reinforced connection structure to prevent the floor slabs from separating from the adobe walls in Tibetan-style fortified houses.

Abstract

This utility model discloses a reinforced connection structure to prevent the floor slab from separating from the adobe wall in a Tibetan-style fortified house. It includes several angle steels, tie bolts (first and second), and nuts. A through hole is formed in the floor slab, with angle steels on both outer sides of the through hole. The angle steels are fixed to the floor slab by the tie bolts and nuts. The end of the floor slab is sealed to the adobe wall with polyurea grout. The other end of the angle steels is connected to the adobe wall by nuts, tie bolts (second), and a steel plate. The reinforcement method designed in this utility model is scientifically sound and innovatively employs a rubber-based elastic colloid for synergistic reinforcement of the floor slab and adobe wall. Combined with the strengthening effect of the tie bolts, it improves the tensile strength of the joints while preserving the sliding energy dissipation mechanism between the floor slab and the adobe wall, enhancing seismic energy dissipation. The combined action of the rubber-based elastic colloid and the high-strength tie bolts reduces the likelihood of the floor slab continuously separating, ultimately completing the reinforcement of the load-bearing wooden components of the Tibetan-style fortified house.

Description

Technical Field

[0001] This utility model relates to the field of construction, and in particular to a reinforced connection structure for preventing the floor slab from separating from the adobe wall in a Tibetan-style watchtower. Background Technology

[0002] The floor system of Tibetan-style fortified houses consists of a composite layer of thin stone slabs and straw, approximately 200mm thick. Its bending stiffness is far lower than that of concrete floor slabs, and there is no effective connection between the floor slab and the adobe walls. Under earthquake conditions, slippage occurs at the interface between the floor slab and the adobe walls, significantly increasing the risk of overall floor failure.

[0003] Current reinforcement technologies generally neglect the collaborative stress-bearing characteristics of the "earthen walls-floor slabs" in Tibetan-style fortified houses. While external angle steel confinement can limit floor slab displacement, the floor slab and adobe walls cannot form an effective force transmission system, resulting in reduced energy consumption. Although epoxy resin grouting can fill gaps, its elastic modulus after curing far exceeds that of the adobe (0.3-0.5 GPa), forming "rigidly bonded patches," leading to shear stress concentration at the interface and causing the adobe to collapse. Therefore, it is necessary to design a reinforcement connection structure to prevent the floor slabs from separating from the adobe walls in Tibetan-style fortified houses. By optimizing the deformation coordination between the floor slabs and adobe walls, and simultaneously preventing floor slab separation deformation, this systematically solves the reinforcement problems of local or overall collapse caused by earthquake damage due to floor slab separation in Tibetan-style fortified houses. Utility Model Content

[0004] The purpose of this invention is to provide a reinforced connection structure to prevent the floor slab from separating from the adobe walls in Tibetan-style fortified houses, thereby solving the aforementioned problems.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model discloses a reinforced connection structure for preventing the floor slab from separating from the adobe wall in a Tibetan-style fortified house. It includes several angle steels, tie bolt 1, tie bolt 2, and nuts matching the tie bolt 1 and tie bolt 2. A through hole 1 is provided on one end of the floor slab near the adobe wall. An angle steel is provided on the outer sides of both ends of the through hole 1. The tie bolt 1 is inserted into the through hole 1. Both ends of the tie bolt 1 pass through through holes in the angle steel and are fixed to the angle steel by nuts. The end of the floor slab is filled with polyurea grout between it and the adobe wall. The tie bolt 2 is connected to the through hole of the angle steel by nuts. The other end of the tie bolt 2 passes through the through hole 2 in the adobe wall and is connected to the steel plate by nuts.

[0007] Furthermore, both perforations one and two are filled with polymer-modified cement mortar.

[0008] Furthermore, the angle steel is L-shaped.

[0009] Furthermore, the thickness of the adobe wall is 490-510 mm.

[0010] Furthermore, the thickness of the floor slab is 190-210mm.

[0011] Furthermore, the steel plate, perforation one, and perforation two are each provided with a plurality of holes, and the distance between two adjacent steel plates is 2000mm.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] The reinforcement method designed in this utility model is scientific and reasonable. It innovatively adopts rubber-based elastic colloids to reinforce floor slabs and adobe walls in synergy, and the strengthening effect of tie rods is added to improve the pull-out bearing capacity of the joints. At the same time, it retains the sliding energy dissipation mechanism of floor slabs and adobe walls to improve the seismic energy dissipation capacity. Under the combined action of rubber-based elastic colloids and high-strength tie rods, the continuous detachment of floor slabs is reduced, and the reinforcement construction of the load-bearing wooden components of Tibetan-style watchtowers is finally completed.

[0020] Example 1

[0021] like Figure 1-2 As shown, a reinforced connection structure for preventing the floor slab from separating from the adobe wall in a Tibetan-style watchtower includes several angle steels 5, tie bolts 1 3, tie bolts 2 9, and nuts 4 that match the tie bolts 1 3 and tie bolts 2 9.

[0022] The angle steel 5 is L-shaped.

[0023] A through hole 10 is provided on one end of the floor slab 2 near the adobe wall 1. Angle steel 5 is provided on both outer sides of the through hole 10. The tie bolt 3 is inserted into the through hole 10. The two ends of the tie bolt 3 pass through the through holes opened on the angle steel 5 and are fixed to the angle steel 5 by nuts 4. The end of the floor slab 2 and the adobe wall 1 are filled with polyurea grout 7. After the polyurea grout 7 solidifies, it forms a rubber-like elastic colloid, which allows the floor slab 2 and the adobe wall 1 to deform in coordination. At the same time, the solidified polyurea grout 7 has good adhesion, preventing the floor slab 2 from separating from the adobe wall 1.

[0024] A tie bolt 9 is connected to the through hole at the other end of the angle steel 5 by a nut 4. The other end of the tie bolt 9 passes through the through hole 11 opened in the adobe wall 1 and is connected to the steel plate 8 by a nut 4.

[0025] Both perforations 10 and 11 are filled with polymer-modified cement mortar 6.

[0026] The thickness of the adobe wall 1 is 490-510mm.

[0027] The thickness of the floor slab 2 is 190-210mm.

[0028] The steel plate 8, the first perforation 10 and the second perforation 11 are each provided with a number of holes, and the distance between two adjacent steel plates 8 is 2000mm.

[0029] Example 2

[0030] like Figure 3-4 As shown, with other structures remaining unchanged, the floor slab 2 on the other side is also connected to the adobe wall 1 as in Embodiment 1. Instead of using steel plate 8 to fix the tie bolts 9, it is fixed by angle steel 5 on the floor slab 2 on the other side.

[0031] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
