Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a node structure of a two-structure wall with a rear lintel after a hole is opened. Background Art

[0002] During the construction process of commercial projects, due to factors such as business adjustments, there is often a need to open a hole after the construction of the second structure wall is completed. After the hole is opened, a lintel needs to be constructed on the top. The traditional method of post-installing the lintel is to remove the second structure wall from the lintel position to the top of the wall, drill a hole, cast the lintel, and then rebuild the upper wall. The construction period is long, the workload is large, and a large amount of material is wasted. Therefore, it is necessary to provide a node structure for the post-installation of the lintel after the hole is opened in the second structure wall, which can solve the problems of long construction period, large workload, and material waste of the post-installation lintel node in the prior art. Summary of the invention

[0003] The utility model aims to provide a node structure of a two-structure wall opening with a rear lintel, which can solve the problems of long construction period, heavy workload and material waste of the rear lintel node in the prior art.

[0004] The utility model is achieved in this way:

[0005] A node structure for a lintel placed after a hole is opened in a second structural wall, comprising fixed embedded parts and tie members; the fixed embedded parts are long strip structures with an L-shaped cross-section, the horizontal section of the fixed embedded parts is inserted into the second structural wall, and the vertical section of the fixed embedded parts is attached to the wall surface of the second structural wall; a pair of fixed embedded parts are symmetrically inserted on the wall surfaces on both sides of the second structural wall, and a plurality of tie members are respectively and spaced and tied between the horizontal sections of the pair of fixed embedded parts to form a wall support structure, so that the wall support structure is supported on the bottom of the second structural wall above the hole.

[0006] The horizontal section of the fixed embedded part is inserted into the brick joint of the two structural walls.

[0007] The elevation of the horizontal section of the fixed embedded part is consistent with the elevation of the top surface of the opening, and the two ends of the fixed embedded part extend symmetrically to the outside of the two ends of the top of the opening.

[0008] The vertical sections of the fixed embedded parts are fixed on the wall surfaces of the two structural walls through connecting parts.

[0009] The length direction of the anchor is consistent with the thickness direction of the two structural walls, and the spacing between the anchors does not exceed 300 mm.

[0010] Its characteristic is that: positioning screw rods are vertically penetrated through the two structural walls, and the two positioning screw rods are symmetrically arranged with respect to the opening and are respectively located at two ends of the fixed embedded parts.

[0011] The vertical section of the fixed embedded part is installed below the top plate through a suspension rod, and a pair of suspension rods are symmetrically arranged about the midpoint of the fixed embedded part.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model is provided with fixed embedded parts and anchors. The fixed embedded parts are buried in the second structural wall at the elevation of the top surface of the opening, which can support the wall above the opening. At the same time, a pair of fixed embedded parts are tied into a whole by multiple anchors to ensure the structural stability and construction safety of the opening during the excavation process, avoid the demolition of excess walls except the opening, and make the construction simpler. There is no need to wait for the lintel to be cured after the lintel is cast, which is conducive to improving construction efficiency, saving construction time and labor, and reducing construction efficiency.

[0014] 2. The utility model is provided with fixed embedded parts and hangers. The fixed embedded parts ensure support for the upper wall by controlling the depth of penetration into the wall. The fixed embedded parts are installed under the top plate through the hangers. When the penetration depth into the wall is insufficient, the wall load can be transferred to the top plate, thereby ensuring the structural stability and construction safety of the opening during the excavation process.

[0015] 3. The utility model is provided with fixed embedded parts and connecting parts. The horizontal section of the L-shaped fixed embedded part is inserted into the brick joint, and the vertical section of the fixed embedded part is installed on the wall through the connecting part, which avoids excessive damage to the two structural walls and makes the installation of the fixed embedded part simple, convenient and firm, thereby ensuring the support reliability of the fixed embedded part.

[0021] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Embodiment 1:

[0023] Please see attached Figure 1 and attached Figure 2 A node structure of a lintel placed after a hole is opened in a second structural wall, comprising a fixed embedded part 1 and an anchor 2; the fixed embedded part 1 is a long strip structure with an L-shaped cross-section, the horizontal section of the fixed embedded part 1 is inserted into the second structural wall 3, and the vertical section of the fixed embedded part 1 is attached to the wall surface of the second structural wall 3; a pair of fixed embedded parts 1 are symmetrically inserted on the wall surfaces of both sides of the second structural wall 3, and a plurality of anchors 2 are respectively and spaced apart and tied between the horizontal sections of a pair of fixed embedded parts 1 to form a wall support structure, so that the wall support structure is supported on the bottom of the second structural wall 3 above the hole 4.

[0024] Preferably, the fixed embedded part 1 can be made of angle iron, the horizontal section of the angle iron is inserted into the second structural wall 3, and the vertical section of the angle iron is attached to the wall surface of the second structural wall 3, so that the fixed embedded part 1 is stably set on the second structural wall 3, thereby playing a role in supporting the wall above the fixed embedded part 1. When excavating the opening 4 and casting the lintel, there is no need to demolish the entire upper wall.

[0025] The anchor 2 connects a pair of fixed embedded parts 1 into a whole, namely, a wall support structure, thereby ensuring stable and reliable support for the wall above the fixed embedded parts 1. At the same time, after the lintel is cast, subsequent construction can be carried out without waiting for the curing of the lintel.

[0026] Please see attached Figure 1 and attached Figure 2 The horizontal section of the fixed embedded part 1 is inserted into the brick joint of the second structural wall 3.

[0027] After cutting with a seam cutter, the horizontal section of the fixed embedded part 1 is inserted into the brick seam of the second structural wall 3, which facilitates the insertion of the fixed embedded part 1 and minimizes damage to the second structural wall 3.

[0028] Please see attached Figure 1 and attached Figure 2 The elevation of the horizontal section of the fixed embedded part 1 is consistent with the elevation of the top surface of the opening 4, and the two ends of the fixed embedded part 1 extend symmetrically to the outside of the two ends of the top of the opening 4.

[0029] Both ends of the fixed embedded parts 1 need to have a certain depth of penetration into the wall, so as to transfer the weight of the wall above the opening 4 to the walls on both sides of the opening 4 to ensure structural safety. The depth of penetration of the ends of the fixed embedded parts 1 into the wall can be adaptively adjusted according to the actual load requirements. Usually, the depth of penetration of the ends of the fixed embedded parts 1 into the wall is consistent to ensure force balance.

[0030] Please see attached Figure 1 and attached Figure 2 The vertical section of the fixed embedded part 1 is fixed on the wall surface of the second structural wall 3 through the connecting part 5.

[0031] Preferably, the connector 5 can be made of self-tapping screws or the like, which are used to fix the vertical section of the embedded component 1 on the second structural wall 3. The connection is reliable and the installation is convenient. The type of connector 5 can also be adaptively selected according to actual installation requirements.

[0032] The length direction of the anchor 2 is consistent with the thickness direction of the second structural wall 3, and the arrangement spacing of the anchor 2 does not exceed 300 mm.

[0033] Preferably, the anchor 2 can be made of flat iron and welded between the horizontal sections of a pair of fixed embedded parts 1 along the thickness direction of the two structural walls 3, which can provide support for the wall above the top of the opening 4 and improve the structural stability and construction safety of the top of the opening 4. The arrangement spacing of the anchor 2 can be adaptively adjusted according to the actual load-bearing requirements.

[0034] Please see attached Figure 1 and attached Figure 2 The two structural walls 3 are vertically penetrated by positioning screw rods (not shown in the figure), and the two positioning screw rods are symmetrically arranged about the opening 4 and are respectively located at the two ends of the fixed embedded part 1.

[0035] Preferably, the positioning screw rod can be made of steel bars, and is penetrated on the second structural wall 3 according to the elevation of the opening 4 and the depth of the fixed embedded part 1 before installing the fixed embedded part 1, and is used to locate the two ends of the fixed embedded part 1, so as to facilitate the accurate installation of the fixed embedded part 1. The positioning screw rod can be removed after the wall support structure is formed.

[0036] Embodiment 2:

[0037] The difference between Example 2 and Example 1 is that the embedding depth of the fixed embedded part 1 into the wall cannot meet the design requirements, and the suspension rod 6 is added to ensure the embedding stability of the fixed embedded part 1.

[0038] Please see attached Figure 3 and attached Figure 4 The vertical section of the fixed embedded part 1 is installed below the top plate (not shown in the figure) through a suspension rod 6, and a pair of suspension rods 6 are symmetrically arranged about the midpoint of the fixed embedded part 1.

[0039] Preferably, the hanger 6 can be made of steel bars and used to transfer the weight of the wall above the fixed embedded part 1 to the top plate to avoid structural safety hazards caused by insufficient depth of the end of the fixed embedded part 1 into the wall.

[0040] The remaining structures of Example 2 are the same as those of Example 1 and will not be described again here.

[0041] Please see attached Figure 1 To Attachment Figure 4 , the construction method of the utility model is:

[0042] Step 1: A hole needs to be opened to reinforce the position. Specifically, according to the elevation size of the hole 4, two No. 10 screws are used as positioning screws to penetrate the second structural wall 3 on the top of the hole to ensure that there is no deviation in the positioning of the two ends of the fixed embedded part 1.

[0043] Step 2: Install the fixed embedded part 1. Specifically, use a cutting machine to cut a slit between the two positioning screw rods. After the slit is completed, use an angle iron as the fixed embedded part 1. Drive the horizontal section of the angle iron into the wall surface of the second structural wall 3 along the slit, and fix the vertical section of the angle iron to the second structural wall 3 with self-tapping screws.

[0044] When installing the fixing embedded part 1, both ends of the fixing embedded part 1 need to extend to both sides of the opening 4 by a certain distance, that is, the ends of the fixing embedded part 1 need to have a certain depth into the wall to ensure the structural safety of the second structural wall 3 when opening the hole.

[0045] The fixed embedded parts 1 are symmetrically installed on the wall surfaces on both sides of the second structural wall 3. The installation method of the fixed embedded parts 1 on both sides is the same, which will not be repeated here.

[0046] Step 3: Drill a hole in the second structural wall 3. Specifically, first use a cutting machine to cut slits around the required hole 4, and then use an electric pick to drill the required hole 4 from the middle of the hole to the surrounding areas.

[0047] Step 4: Reinforce the fixed embedded parts 1 on both sides of the second structural wall 3. Specifically, use flat iron as anchors 2 to tie the fixed embedded parts 1 on both sides of the second structural wall 3 every 30 mm, and the fixed embedded parts 1 and the anchors 2 are welded and fixed.

[0048] The width of the opening 4 is L. When 300mm≤L<1600mm, the fixed embedded part 1 adopts 5# angle iron, the anchor 2 adopts 40×4 flat iron, and the depth of both ends of the fixed embedded part 1 into the wall is 300mm. When 1600mm≤L<2200mm, the fixed embedded part 1 adopts 6# angle iron, the anchor 2 adopts 40×4 flat iron, and the depth of both ends of the fixed embedded part 1 into the wall is 500mm. When 2200mm≤L, the fixed embedded part 1 adopts 10# angle iron, the anchor 2 adopts 50×5 flat iron, and the depth of both ends of the fixed embedded part 1 into the wall is 800mm.

[0049] If the depth of the end of the fixed embedded part 1 into the wall cannot meet the above requirement, a pair of suspension rods 6 are symmetrically connected between the top plate and the fixed embedded part 1.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
