Problems solved by technology

In view of this common situation, the traditional method is to use scaffolding to support the floors of each floor layer by layer, so as to reduce the settlement and deformation of the load-bearing wall. It cannot be used normally due to scaffolding, which not only affects the use of the building, but also has the disadvantages of high cost and long construction period
On the other hand, even if scaffolding is used to support the floors of each floor layer by layer, the self-weight load of the wall will still be relatively large.
At present, there is no better way to solve the above-mentioned disadvantages of opening larger openings in load-bearing walls

Embodiment 1

[0030] Embodiment 1: as Figure 1~3 As shown, this embodiment includes the following steps:

[0031] 1) On the wall 11 where the hole 7 needs to be opened, a number of process holes 1 are set at intervals along the same height in the horizontal direction, and monitoring points are arranged;

[0032] 2) Place the prefabricated I-shaped steel support 5 in each of the above-mentioned process holes 1 for supporting the upper ring beam, floor and wall 6, and place the steel support 5 behind each process hole 1, Use a steel wedge to tighten the upper and lower sides of the steel support and the process hole, and then fill the gap between the steel support and the inner wall of the process hole with high-strength non-shrinkage grouting material or epoxy mortar.

[0033] 3) After the grouting material of the process holes opened at intervals for the first time reaches the design strength, other process holes are opened at intervals, and the prefabricated I-shaped steel support 5 is p...

Embodiment 2

[0041] Example 2, such as Figure 4 , 5 shown. This embodiment is basically the same as Embodiment 1, except that the steel support is a square-shaped steel support 9, and the axial direction of the square-shaped steel support is parallel to the horizontal direction of the wall. Pass the steel plates forming the zigzag steel structure support beam 3 through the zigzag steel support 9 along the direction of the horizontal groove, weld the steel plates forming the zigzag steel structure support girder 3 into a whole, and then connect each zigzag steel support 9 with the zigzag The zigzagging steel structure support beam 3 is welded as one to form an integral steel support beam 2, and then the zigzag steel structure support beam 3 is poured compactly with fine stone concrete or high-strength non-shrinkage grouting material. The width of zigzag steel bearing 9 is wider than the thickness of body of wall 1cm.

Embodiment 3

[0042] Embodiment 3 is basically the same as Embodiment 1, except that the steel support adopts a square steel support 9, and the axial direction of the square steel support is parallel to the horizontal direction of the wall. Pass the steel plates forming the I-shaped steel structure support beam 8 through the mouth-shaped steel support 9 along the direction of the horizontal groove, weld the steel plates forming the I-shaped steel structure support beam 8 into a whole, and then connect each mouth-shaped steel support 9 with the I-shaped steel support Zigzag steel structure support beam 8 is welded as a whole, becomes integral type steel support beam 2. The width of zigzag steel bearing 9 is wider than the thickness of body of wall 2cm.

Abstract

The invention relates to a method for opening a cave in a self-balancing type supporting and load bearing wall body. The method comprises the following steps of: drilling a plurality of process holes on the upper part of a wall body requiring a cave along the direction of the wall body; placing prefabricated steel supporting seats in each process hole; cutting the wall body along the horizontal direction among all the steel supporting seats open to form a horizontal groove and communicating all the process holes; enabling preset steel plates for forming a steel-structured supporting beam to pass through each steel supporting seat along the direction of the horizontal groove and welding to form the steel supporting beam; welding the steel supporting beam with all the steel supporting seatsto form an integral type steel supporting beam; drilling at least two vertical process long holes used for arranging supporting pillars on the wall body below the integral type steel supporting beam;applying the supporting pillars and lower bases thereof into the vertical process long holes; and after a designed strength is reached, dismantling the wall body enclosed among the integral type steel supporting beam and the supporting pillars by segments to form a required cave. By adopting the method, the cave is opened on the load bearing wall without setting up scaffolds layer by layer and influencing the use of an upper building, and the method has the advantages of convenience, rapidness, low cost, good effect, safety, reliability, and the like.

Description

technical field [0001] The invention relates to the technical field of civil construction engineering, in particular to a method for opening holes in a self-balancing supporting load-bearing wall. technical background [0002] As the market demand changes, the use function of the original building often changes, and it is necessary to renovate the existing building. Among them, it is often necessary to open a larger opening in the load-bearing wall, such as opening a hole in the load-bearing wall. Larger openings are used as commercial or business places to expand the overall connected area of ​​a certain floor. In view of this common situation, the traditional method is to use scaffolding to support the floors of each floor layer by layer, so as to reduce the settlement and deformation of the load-bearing wall. It cannot be used normally due to scaffolding, which not only affects the use of the building, but also has the disadvantages of high cost and long construction per...
