Description

Technical Field

[0001] The present invention relates to the technical field of building structure reinforcement, and in particular to a reinforcement structure for newly opening door and window openings on a brick wall structure. Background Art

[0002] With the increasing urbanization level in China, there are more and more renovation projects for old residential areas. Due to the need for building function changes in some old masonry buildings, it is often necessary to newly open large-span door and window openings on the brick walls of the building facades. Before opening the holes, most of them need to be reinforced to improve the safety during the hole-drilling operation and avoid cracks in the wall. There are two common reinforcement methods in the prior art: One method is the angle steel supporting beam reinforcement method. The specific implementation steps are as follows: First, chisel off the plaster layer at the installation position on the wall for installing the angle steel, and remove the horizontal joint mortar on one side of the installation position. Then, fill the horizontal joint with clay mortar, and correspondingly embed the angle steel. The same operation is carried out on the other side, and the two sides are reinforced by bolt connection. Then, remove the wall within the hole range, and connect the bottoms of the two angle steels through gusset plates. This construction method has the advantages of convenient construction and short construction period, but the bearing capacity of the reinforcement structure is relatively low. Therefore, it is generally applicable to holes with a width within 1.2 m and cannot be applied to holes with a larger width; The other is the reinforced concrete supporting beam reinforcement method. The specific implementation steps are as follows: First, perform local drilling at the position on the wall for placing the supporting beam, and correspondingly place steel bracing members in the holes. Then, remove the other walls at the positions for placing the supporting beam, and correspondingly bind steel bars and pour concrete at these positions. After the supporting beam structure reaches the design strength, remove the wall within the hole range. Due to the existence of steel bracing members in this reinforcement method, it is difficult to bind the steel bars. Although the bearing capacity of the reinforcement structure is higher than that of the angle steel supporting beam reinforcement method, it can still only be applied to holes with a width within 2 m. Both of the above two reinforcement methods have the problem of large limitations in the applicable range.

[0003] In view of the problems existing in the above-mentioned prior art, it is urgent to design a reinforcement structure for newly opening door and window openings on a brick wall structure to solve the above problems. Summary of the Invention

[0004] In order to overcome the technical problems existing in the prior art, the present application provides a reinforcement structure for newly opening door and window openings on a brick wall structure and its preparation method, so as to solve the problems proposed in the above background art.

[0005] The present application provides a reinforcement structure for newly opening door and window openings on a brick wall structure, including:

[0006] At least a pair of side support members, and the two side support members are respectively penetrated through both sides of the wall corresponding to the door and window openings to be opened;

[0007] A reinforcing member, the reinforcing member spanning above the opening of the door or window to be opened, and both ends of the reinforcing member being correspondingly placed on the side support members;

[0008] A plurality of connecting members, the connecting members passing through the reinforcing member and the wall body so that the reinforcing member and the wall body are fixedly connected.

[0009] A support beam is formed by the reinforcing member supported by the side support members. At the same time, the channel steel is connected to the wall body through a plurality of connecting members, so that the channel steel and the wall body can form an integral whole, improving the structural stability and effectively preventing cracks from appearing in the wall body due to the later opening of the door or hole.

[0010] In some embodiments, the side of the reinforcing member close to the opening of the door or window to be opened is correspondingly coincident with the top edge of the opening of the door or window to be opened.

[0011] In some embodiments, the length of the reinforcing member is greater than the distance between the two farthest side support members.

[0012] By setting the side of the reinforcing member close to the opening of the door or window to be opened to completely coincide with the side of the opening of the door or window to be opened, it can provide a clear construction position for the subsequent work of opening the door or window opening, making the construction have obvious dimensional boundaries, effectively avoiding errors caused by unclear boundaries during the construction process, and thus effectively improving the construction accuracy.

[0013] In some embodiments, the number of the reinforcing members is two, and the two reinforcing members are symmetrically arranged on the two wall surfaces of the wall body.

[0014] By setting two reinforcing members symmetrically installed on the two wall surfaces of the wall body, it can further strengthen the supporting effect of the reinforcing member on the structure above the masonry wall, effectively improving the supporting capacity and structural strength of the reinforcing structure, and further providing the stability and reliability of the reinforcing structure.

[0015] In some embodiments, the connecting member passes through the two reinforcing members at the same time to connect the two reinforcing members.

[0016] By setting the connecting member to connect the two reinforcing members, the reinforcing member can be supported by all the side support members at the same time, and thus a greater supporting force can be provided for the reinforcing member.

[0017] In some embodiments, the gap between the side support member and the reinforcing member is filled with steel split pieces.

[0018] By tightly packing with steel wedges between the side supports and the reinforcement members, the side supports and the reinforcement members can be firmly connected, thereby effectively improving the compactness of the overall reinforcement structure, making the side supports and the reinforcement members integrated, effectively enhancing the overall stiffness, significantly improving the bearing capacity and strength of the overall structure, and also facilitating the dispersion and absorption of stresses generated by external influences (such as temperature changes, earthquakes, etc.), thereby improving the stability and service life of the reinforcement structure. In addition, it can also effectively speed up the construction speed, significantly shorten the construction period, and reduce labor costs.

[0019] The present invention has at least the following beneficial effects:

[0020] 1. By erecting a pair of side supports on both sides of the door and window openings to be opened, and then using the reinforcement members to span and connect the wall structure above the door and window openings to be opened, it is possible to support the load of the upper part of the wall structure, and it is also possible to flexibly adjust the side supports and the reinforcement members according to the size of the opening and the magnitude of the upper load to meet the bearing capacity requirements of the reinforcement structure for openings of various spans, effectively expanding the applicable range of the reinforcement structure and enabling the reinforcement structure to meet the construction requirements for openings wider than two meters;

[0021] 2. It realizes the construction of first adding side supports for reinforcement and then opening the hole, which is convenient and reliable for construction, avoids the cumbersome procedures and high risks of traditional methods, and effectively improves the safety factor of construction operations.

[0032] The present application provides a reinforcement structure for a newly opened door and window opening 11 in a brick wall structure. Please refer to Figures 1 to 2 , which includes at least a pair of side supports 20, a reinforcement member 30, and a plurality of connecting members 31. The two side supports 20 are respectively arranged through the two sides of the wall 10 corresponding to the to-be-opened door and window opening 11. The reinforcement member 30 spans above the to-be-opened door and window opening 11, and the two ends of the reinforcement member 30 are correspondingly placed on the side supports 20. The connecting members 31 are arranged through the reinforcement member 30 and the wall 10 to fixedly connect the reinforcement member 30 and the wall 10.

[0033] Specifically, the side support member 20 may be a square steel pipe, and the reinforcement member 30 may be a channel steel. First insertion holes are respectively formed on both sides of the wall body 10 corresponding to the opening and closing window opening 11 for the opening and closing window opening 11. A distance is left between the first insertion hole and the side of the opening and closing window opening. Two square steel pipes are correspondingly inserted into the first insertion holes perpendicularly to the wall body 10. At the same time, both ends of the square steel pipe extend out of the first insertion hole. The channel steel is correspondingly arranged on the two square steel pipes. The channel steel forms a support beam under the support of the square steel pipes. At the same time, the channel steel is connected to the wall body 10 through a plurality of connecting members 31, so that the channel steel and the wall body 10 can form an integral body, improving the structural stability and effectively preventing cracks from appearing in the wall body 10 due to subsequent opening of doors or holes.

[0034] It should be noted that the reinforcement member 30 may also be an I-beam or a full-length steel plate. The specific material of the reinforcement member 30 can be determined according to actual needs and is not limited herein.

[0035] In some embodiments, please refer to Figures 1 to 2 , the side of the reinforcement member 30 close to the opening and closing window opening 11 coincides with the top side of the opening and closing window opening 11.

[0036] Specifically, the side of the reinforcement member 30 close to the opening and closing window opening 11 completely coincides with the side of the opening and closing window opening 11, so as to provide a clear construction position for the subsequent work of opening the window opening 11, with obvious dimensional boundaries for construction, effectively avoiding errors caused by unclear boundaries during the construction process, and thus effectively improving the construction accuracy.

[0037] In some embodiments, please refer to Figure 1 and Figure 2 , the length of the reinforcement member 30 is greater than the distance between the two farthest side support members 20.

[0038] Specifically, when the number of side support members 20 is two pairs or more, the length of the reinforcement member 30 is longer than the distance between the two farthest side support members 20, so that the reinforcement member 30 can be supported by all the side support members 20 at the same time, and thus a greater supporting force can be provided for the reinforcement member 30.

[0039] In some embodiments, please refer to Figure 1 and Figure 2 , the number of the reinforcement members 30 is two, and the two reinforcement members 30 are symmetrically arranged on the two wall surfaces of the wall body 10.

[0040] Specifically, two reinforcing members 30 are symmetrically arranged on two wall surfaces of the wall body 10, so as to further strengthen the supporting effect of the reinforcing members 30 on the structure above the masonry wall body 10, effectively improve the supporting capacity and structural strength of the reinforcing structure, and further provide the stability and reliability of the reinforcing structure.

[0041] In some embodiments, please refer to Figure 1 and Figure 2 , the connecting member 31 penetrates through the two reinforcing members 30 at the same time to connect the two reinforcing members 30.

[0042] Specifically, the connecting member 31 can be a connecting bolt, and a plurality of mounting holes corresponding to the connecting bolts one by one are formed on the reinforcing member 30, so that when the reinforcing member 30 is installed, it is ensured that the connecting bolt can penetrate out of the reinforcing member 30 for easy fixing, so that the two reinforcing members 30 can correspondingly clamp the wall body 10 to exert a greater supporting effect on the wall body 10, and also effectively improve the structural strengthening effect of the overall reinforcing structure.

[0043] In some embodiments, please refer to Figure 1 and Figure 2 , a steel splitting member is filled in the gap between the side supporting member 20 and the reinforcing member 30.

[0044] Specifically, by using a steel splitting member to firmly fill between the side supporting member 20 and the reinforcing member 30, the side supporting member 20 and the reinforcing member 30 can be firmly connected, thereby effectively improving the compactness of the overall reinforcing structure, making the side supporting member 20 and the reinforcing member 30 form an integral body, effectively improving the overall stiffness, significantly improving the overall structural bearing capacity and strength, and also being beneficial to dispersing and absorbing the stress generated by external influences (such as temperature changes, earthquakes, etc.), thereby improving the stability and service life of the reinforcing structure. In addition, it can also effectively speed up the construction speed, significantly shorten the construction period, and reduce the labor cost.

[0045] The method of using the reinforcing structure of the present utility model to make door and window openings 11 on the wall body 10 includes the following contents:

[0046] Set up a temporary support replacement near the wall body 10 above the design position of the door opening or window opening to support the surrounding floor slabs;

[0047] Knock off the plaster on the wall body 10 above the design position of the door opening or window opening to expose the brick body;

[0048] On both sides of the wall body 10 corresponding to the design position of the door opening or window opening, drill first through holes for inserting the side supporting members 20, and then drill a plurality of anchor bolt holes on the wall body 10 between the two first through wall holes with an electric drill;

[0049] Insert the side support member 20 into the first through-wall hole, and make both ends of the side support member 20 extend out of the first insertion hole. Install the reinforcement members 30 at both ends of the side support member 20 corresponding to the extension out of the first through-wall hole, that is, symmetrically install the reinforcement members 30 on both sides of the wall body 10;

[0050] Pass the connecting bolts one by one through the installation holes and anchor bolt holes on the reinforcement member 30, and then tighten the nuts to fix the reinforcement member 30 on the wall body 10;

[0051] Mark the door opening line, cut the wall body 10 along the line with a hacksaw, and after cutting, knock out the brick wall at the door opening (or window opening) to carry out the hole-opening construction;

[0052] Pour concrete at the door opening (or window opening) to form a replacement beam-column frame;

[0053] After the replacement beam-column frame reaches the design strength, remove the side support member 20 and the reinforcement member 30 above the hole 11;

[0054] Backfill the first insertion hole with bricks and fill it solid with mortar; fill the anchor bolt holes solid with mortar.
