Description

Technical Field

[0001] The utility model relates to the technical field of wall reinforcement and reconstruction construction, in particular to a support and reinforcement structure for an enclosure wall of a bent frame factory building. Background Art

[0002] During the renovation of older industrial plants, column-bent foundation reinforcement is often required according to structural design requirements. The outer retaining walls of older industrial plants are non-load-bearing structures, lacking effective connections to the column-bents. The base of the outer retaining wall typically lies above the column-bent foundations. During foundation reinforcement, the outer retaining wall requires excavation or the removal of sections of the wall, leaving the wall suspended in the air. Supporting the retaining wall to ensure lateral stability is a challenging construction challenge.

[0003] Traditional construction methods involve two steps for unloading and supporting the structure: 1. Wall unloading: To ensure the stability of the masonry wall, I-beams are installed perpendicular to the wall, using steel beams and jacks for unloading support. 2. Wall support: Full-height scaffolding is erected on both sides of the wall, supporting the wall.

[0004] However, the traditional construction technology has the following disadvantages: (1) the construction process is complicated, the workload is large, and the construction period is long; (2) the I-beams, scaffolding and reinforced foundations often conflict with each other, causing construction inconvenience; (3) the I-beams need to be filled with cement mortar at the part where they pass through the wall, which is difficult to remove later and inconvenient for the turnover of the I-beams; (4) in the process of installing the I-beams, it is necessary to drill a hole in the wall first, which causes great damage to the original structure, and the wall is prone to overturning, which poses a greater construction risk. Utility Model Content

[0005] The purpose of the utility model is to provide a support and reinforcement structure for the enclosure wall of a bent frame factory building to solve the technical problems described in the background technology.

[0006] In order to achieve the above technical objectives, the present invention adopts the following technical solutions:

[0007] A support and reinforcement structure for the enclosure wall of a frame factory building, comprising a wall-attached joist, a wall-attached steel plate strip, a supporting beam and an oblique strut. The wall-attached joist and the wall-attached steel plate strip are both horizontally attached to the outer facade of the enclosure wall and fixed to the enclosure wall by tension bolts, and the wall-attached steel plate strip is arranged above the wall-attached joist. The supporting beam is arranged at intervals along the wall-attached joist, one end of which is vertically fixed to the supporting wall joist, and the other end extends to the outside of the enclosure wall and is connected and fixed to a pier foundation set on the floor. The oblique strut is arranged at an angle, and its top end is connected and fixed to a connecting ear fixedly provided on the wall-attached steel plate strip, and its bottom end is connected and fixed to a connecting ear fixedly provided at the end of the supporting beam.

[0008] Preferably, it also includes an oblique cable, which is arranged obliquely and is in a taut state, with its top end connected and fixed to the connecting ear fixedly arranged on the wall-attached steel plate strip, and its bottom end connected and fixed to the connecting ear fixedly arranged at the end of the supporting beam.

[0009] Preferably, the tension bolts are distributed in an alternating manner up and down along the extension direction of the wall-attached joist or the wall-attached steel plate strip.

[0010] Preferably, vertical supports are further included, which are arranged at intervals below the retaining wall at the excavation position, with their bottom ends resting on the soil of the excavation surface and their top ends resting on the bottom end surface of the retaining wall.

[0011] Preferably, the oblique cables are made of steel wire ropes or steel bars.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention has a simple structure and is easy to construct. By using tension bolts to fix the attached wall support beams and the attached steel plate strips on the retaining wall, and further using the attached support beams as the attachment support points for the supporting beams, and using the attached steel plate strips as the attachment support points for the diagonal struts and the diagonal cables, the problem of needing to drill holes in the retaining wall is avoided. Moreover, the integrity of the reinforced section of the retaining wall is better, and the top-pull combined support method further improves the support and reinforcement quality of the retaining wall, ensuring the stability of the wall and construction safety.

[0022] The following describes the principles and features of the present invention in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention. Figure 1-4 , the preferred embodiments of the present invention are further described in detail:

[0023] like Figure 1-2 As shown, the utility model is preferably a support and reinforcement structure for the enclosure wall of a bent factory building, including a wall joist 3, a wall steel plate belt 8, a supporting beam 5 and an oblique brace 9. The wall joist 3 and the wall steel plate belt 8 are both horizontally attached to the outer facade of the enclosure wall 1 and fixed to the enclosure wall 1 by tension bolts 4, and the wall steel plate belt 8 is arranged above the wall joist 3, as shown in FIG. Figure 3-4As shown, the tension bolts 4 are distributed in an alternating manner along the extension direction of the wall joist 3 or the wall steel plate strip 8, and the supporting beams 5 are arranged at intervals along the wall joist 3, one end of which is vertically fixed to the supporting wall joist 3, and the other end extends to the outside of the retaining wall 1 and is connected and fixed to the pier foundation 7 set on the floor. The diagonal brace 9 is set at an angle, and its top end is connected and fixed to the connecting ear 6 fixedly provided on the wall steel plate strip 8, and its bottom end is connected and fixed to the connecting ear 6 fixedly provided at the end of the supporting beam 5;

[0024] Among them, the wall-attached joists 3, the wall-attached steel plate strips 8, the supporting beams 5 and the diagonal braces 9 can be arranged according to the actual reinforcement requirements of the wall and the construction conditions (such as whether the wall is tilted, the tilt direction of the wall, whether there are obstructions on both sides of the wall, etc.), for example, they can be arranged on one side of the enclosure wall 1 or on both sides of the enclosure wall 1. Moreover, the arrangement of the supporting beams 5 on both sides of the enclosure wall 1 can be symmetrical or staggered.

[0025] Moreover, the wall joists 3 and the wall steel strips 8 are fixed to the retaining wall 1 by tension bolts 4, and there is no need to open a large hole in the retaining wall 1. Figure 1 As shown, the layout range of the wall joists 3 and the wall steel strips 8 needs to cover the wall at least one column spacing outside the bent columns 2 at the excavation position. At this time, the wall of the excavation section is subjected to the force as a whole through the wall joists 3 and the wall steel strips 8, and the integrity is better.

[0026] In certain preferred embodiments, in order to further improve the reinforcement effect of the excavation section retaining wall 1, an oblique cable 10 is further provided. The oblique cable 10 is arranged obliquely and is in a taut state. The top end of the oblique cable 10 is connected and fixed to the connecting ear 6 fixedly provided on the wall-attached steel plate strip 8, and the bottom end of the oblique cable 10 is connected and fixed to the connecting ear 6 fixedly provided at the end of the supporting beam 5. The oblique cable 10 can be made of steel wire rope or steel bar. The taut oblique cable 10 can construct prestress in the triangular structure formed by the retaining wall 1, the supporting beam 5 and the oblique support rod 9, making the entire reinforcement system more stable.

[0027] Of course, if Figure 2 As shown, in some preferred embodiments, vertical supports 11 can be further provided at the bottom of the retaining wall 1. The vertical supports 11 are arranged at intervals below the retaining wall 1 at the excavation position, with their bottom ends resting on the soil of the excavation surface and their top ends resting on the bottom end surface of the retaining wall 1. The vertical supports 11 are used to support and unload the excavation section wall, thereby further improving the stability of the wall.

[0028] The specific construction process of this utility model is as follows:

[0029] Step 1: According to the position of the supporting beam 5, a concrete pier foundation 7 is set at the end, and a steel plate is embedded on the top of the pier foundation 7;

[0030] Step 2: Grind the bottom of the retaining wall 1 to ensure that the channel steel wall joist 3 can fit tightly against the wall surface. Stagger bolt holes on the retaining wall 1, install the tension bolts 4, and fill the holes with anchor glue.

[0031] Step 3: After the strength of the anchor glue reaches the design strength requirement, install the channel steel wall joist 3;

[0032] Step 4: Weld the connecting plate to the channel steel wall joist 3, install the supporting beam 5, bolt one end of the supporting beam 5 to the connecting plate of the wall joist 3, and fix the other end to the embedded plate on the top of the end concrete pier foundation 7;

[0033] Step 5: Use a lift or other machinery to install the wall-attached steel strips 8 on both sides of the upper part of the wall. The wall-attached steel strips 8 are fixed with staggered tension bolts 4.

[0034] Step 6: Use a car crane with a lift to install the diagonal brace 9 and the diagonal cable 10, and ensure that the diagonal cable 10 is in a taut state. After the wall support reinforcement structure is completed, it must be inspected and accepted before subsequent earthwork excavation can be carried out;

[0035] Step 7: Excavate the foundation of bent column 2 using a step-by-step excavation method. When mechanically excavating the foundation, the soil at the bottom of retaining wall 1 must be retained. The soil at the bottom of retaining wall 1 is manually excavated, and wooden planks, adjustable U-supports, steel pads, etc. are used as vertical supports 11 to temporarily support the bottom of the wall.

[0036] Step 8: Construction and maintenance of foundation reinforcement of bent column 2;

[0037] Step 9: Backfill soil for bent column 2 foundation and compact it layer by layer;

[0038] Step 10: Remove the diagonal bracing rods 9 and diagonal cables 10, the supporting beams 5, the wall joists 3 and the wall steel strips 8;

[0039] Step 11: Repeat the above steps to reinforce the foundation of the frame column 2 at the subsequent position. The adjacent foundation excavation should be carried out after the foundation strength on both sides reaches more than 75% of the design strength and the foundation backfill is completed.

[0040] The process principle of the present invention is as follows: a double-channel steel wall joist 3 is set at the bottom of the retaining wall 1, and the wall joist 3 is connected to the wall through tension bolts 4. The wall joist 3 is connected to the supporting beam 5 through a connecting plate, and the diagonal brace rod 9 and the diagonal cable 10 are further used to support and unload the wall.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
