Description

Technical Field

[0001] The invention relates to the technical field of steel structure reinforcement, and in particular to a method for reinforcing a raw earth building steel structure and a reinforcement structure. Background Art

[0002] Earthen buildings refer to buildings that use unfired and simply processed original earth as the main material to create the main structure. It started with artificial digging of holes and has a long history. From the beacon towers, tombs and ancient city ruins left over from ancient times, we can see that the ancients used earth to build buildings. Earthen buildings are widely distributed and almost all over the world. Earthen buildings are divided into loess cave dwellings, adobe cave dwellings, adobe buildings, rammed earth walls or straw mud wall buildings and various "earth-covered buildings", as well as large-volume structures of rammed earth. According to the construction method and use function, there are cave dwellings, other earthen buildings and public buildings built with earthen materials.

[0003] The waterproof performance of earth buildings is poor, and special waterproofing measures are needed to prevent rainwater leakage. In addition, earth buildings are easily affected by weather during construction and generally need to be reinforced. There are usually two reinforcement methods.

[0004] 1. Add a new frame structure as the load-bearing structure of the house. The original earth wall no longer bears the load and only serves as a retaining wall or decorative wall. This method cannot effectively utilize the original wall, the original wall and the new structure cannot be effectively connected, the economy is not good, and the safety of the original wall is not improved.

[0005] 2. Use the method of setting penetrating steel wires in the wall and setting steel wire mesh on the wall surface to reinforce the raw earth wall. This method requires comprehensive work on the original earth wall, has a long construction period, and will add a layer of concrete reinforcement to the raw earth wall surface, which will destroy the air permeability of the original earth wall, and has a high cost. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a method and a reinforcement structure for reinforcing a raw earth building steel structure. The reinforcement method and the reinforcement structure not only have a short reinforcement period and low cost, but also can effectively improve the safety of the original wall.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0008] A method for reinforcing a raw earth building steel structure and a reinforced structure, comprising the following steps:

[0009] S1: Measure the verticality between the raw earth wall and the ground at the intersection of the wall;

[0010] S2: According to the force calculation, obtain the appropriate lattice column and steel beam;

[0011] S3: According to the cross-sectional dimensions of the lattice column, corresponding slots are opened at the intersection of the raw soil wall;

[0012] S4: First install the lattice column in the slot;

[0013] S5: Then install the steel beam between two adjacent lattice columns;

[0014] S6: Fix the bottom of the lattice column to the raw earth wall foundation and connect the top to the steel beam;

[0015] S7: Fill the gap between the lattice column and the raw earth wall.

[0016] Preferably, in step S1, a measuring instrument is used to measure the verticality of the raw earth wall at the intersection of the walls and the ground. If the raw earth wall is not vertical to the ground, the existing technology and materials are used to make the raw earth wall vertical to the ground; if the raw earth wall is already vertical to the ground, S2 is performed.

[0017] Preferably, the step S2 simulates the actual situation of the earth building through software such as PKPM, and according to the force mode, combined with the intersection of the earth wall, calculates and obtains lattice columns and steel beams that are exactly equal to the width of the earth wall.

[0018] Preferably, in step S5, the steel beam and the lattice column are rigidly connected.

[0019] Preferably, in step S6, the bottom of the lattice column is fixed to the raw earth wall foundation by anchor bolts.

[0020] Preferably, in step S7, the gap between the lattice column and the raw earth wall is filled with materials such as cement mortar.

[0021] A reinforcing structure of a raw earth building steel structure comprises a raw earth wall, lattice columns arranged on both sides of the raw earth wall, and steel beams installed on the two lattice columns.

[0022] Preferably, the raw earth wall includes a wall body one, a wall body two perpendicular to the wall body one, a wall body three arranged between the wall body two and the wall body one, a notch provided on the wall body three, and a plate hole provided on the notch.

[0023] Preferably, the lattice column comprises four angle steels, and two adjacent angle steels are mounted with a plurality of equally spaced tie plates; the angle steels are mounted on the notches; and the tie plates are inserted into the through-plate holes.

[0024] Compared with the prior art, this application has the following beneficial effects:

[0025] The present invention adopts the method of opening notches and plate holes on the raw earth wall, utilizing the notches and plate holes to add lattice columns, realizing the integration of the raw earth wall and the lattice columns, and effectively improving the safety of the raw earth wall. At the same time, the reinforcement method only needs to open notches and plate holes on the raw earth wall to install the reinforcement structure, which can greatly shorten the reinforcement period. The reinforcement structure is also a simple lattice column plus steel beam method, which has low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0035] Embodiment 1:

[0036] A method for reinforcing a raw earth building steel structure and a reinforced structure, comprising the following steps:

[0037] S1: Use a measuring instrument to measure the verticality of the earth wall 10 at the intersection of the walls and the ground. If the earth wall 10 is not vertical to the ground, use existing technology and materials to make the earth wall 10 vertical to the ground; if the earth wall 10 is already vertical to the ground, proceed to S2;

[0038] S2: The actual situation of the earth building is simulated by software such as PKPM. According to the force mode, the intersection wall of the earth wall 10 is used to calculate and obtain the lattice column 20 and the steel beam 30 that are exactly equal to the width of the earth wall 10;

[0039] S3: according to the cross-sectional dimensions of the lattice column 20, corresponding slot positions are opened at the intersection of the raw earth wall 10;

[0040] S4: First install the lattice column 20 in the slot;

[0041] S5: Install the steel beam 30 between two adjacent lattice columns 20;

[0042] S6: Fix the bottom of the lattice column 20 to the foundation of the raw earth wall 10, and connect the top to the steel beam 30;

[0043] S7: Fill the gap between the lattice column 20 and the raw earth wall 10.

[0044] Furthermore, in step S1, the earth building may deform during use. If these deformations are not dealt with and reinforcement is directly carried out on it, the safety of the reinforced structure may be reduced. Therefore, before reinforcement, it is necessary to first ensure the verticality of the reinforced earth wall 10 and the foundation ground to prevent the reinforced structure from being inclined with the ground after reinforcement, thereby improving the safety of the reinforced structure and increasing the service life of the reinforced structure.

[0045] Furthermore, in order to make the lattice columns 20 and steel beams 30 required for reinforcement fully match the width of the raw earth wall 10 so that the three can fit closely together, step S2 needs to use existing software for calculating structure and force such as PKPM to find the lattice columns 20 and steel beams 30 that best match the current raw earth wall 10.

[0046] Furthermore, in step S5, the steel beam 30 and the lattice column 20 are rigidly connected.

[0047] Furthermore, in step S6, the bottom of the lattice column 20 is fixed to the foundation of the raw earth wall 10 by anchor bolts.

[0048] Furthermore, in step S7, the gap between the lattice column 20 and the raw earth wall 10 is filled with materials such as cement mortar.

[0049] like Figure 1 As shown, a raw earth building steel structure reinforcement structure includes a raw earth wall 10, lattice columns 20 arranged on both sides of the raw earth wall 10, and steel beams 30 installed on the two lattice columns 20.

[0050] The present invention is different from the prior art in that it does not adopt a large-scale moving earth wall 10, but instead utilizes the earth wall 10, combines the lattice columns 20 installed on the earth wall 10 and the steel beams 30 installed on the lattice columns 20 and the earth wall 10, so that the entire wall surface becomes a whole. In this way, not only is the reinforcement simple, but also the cost is low. More importantly, the integrated earth wall 10 can greatly improve the safety of the earth wall 10.

[0051] like Figure 3 and Figure 4 As shown, the raw earth wall 10 includes a wall 11, a wall 2 12 perpendicular to the wall 11, a wall 3 13 arranged between the wall 2 12 and the wall 1 11, a notch 14 opened on the wall 3 13, and a plate hole 15 opened on the notch 14.

[0052] Furthermore, in order to install the lattice column 20 of the reinforcement structure, the present embodiment opens a slot 14 and a plate hole 15 at the intersection of the raw earth wall 10; specifically, the raw earth wall 10 includes a wall 11, a wall 2 12 and a wall 3 13, and the wall 11 and the wall 2 12 are connected through the wall 3 13, and the wall 3 13 is the intersection wall of the raw earth wall 10, so the slot 14 and the plate hole 15 are opened on the wall 3 13.

[0053] like Figures 2 to 4 As shown, the lattice column 20 includes four angle steels 21 , and two adjacent angle steels 21 are mounted with a plurality of equally spaced gusset plates 22 ; the angle steels 21 are mounted on the notches 14 ; and the gusset plates 22 are inserted into the plate holes 15 .

[0054] In this embodiment, through step S2 , it is concluded that the lattice column 20 is composed of four angle steels 21 and equally spaced tie plates 22 for connecting the angle steels 21 .

[0055] According to the specific structure of the lattice column 20, notches 14 of the same shape as the angle steel 21 are chiseled out at the four corners of the wall body 13 using existing tools, and through-plate holes 15 are chiseled out on the wall body 13 at the corresponding positions of the gusset plates 22, and then the four angle steels 21 are embedded in the notches 14, and then the gusset plates 22 are inserted into the through-plate holes 15 and fixed on the two angle steels 21 on the same side. Finally, the lattice column 20 formed tightly wraps the wall body 13 in the main body, and then, the gap between the lattice column 20 and the wall body 13 is filled with materials such as cement mortar to improve the integrity and strength of the lattice column 20 and the wall body 13, thereby improving the safety of the raw earth wall 10.

[0056] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the attached claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any figure mark in the claims should not be regarded as limiting the claims involved.
