TECHNICAL FIELD
[0001] The utility model relates to underground building construction technical field, concretely relates to a middle floor slab change bracing plate belt structure. BACKGROUND
[0002] In the foundation pit engineering construction, when construction reaches the middle layer of structure, floor slab change bracing needs to be added between the fender pile and the outer wall to make the horizontal force received by the fender pile transmitted to the outer wall to increase the structural strength of the fender pile. The traditional method is to pour the outer wall and the floor slab change bracing into a whole and connect with the fender pile through the way of planting a reinforcing bar, which makes the floor slab change bracing constitute a part of the structure. However, although this method increases the stability of the structure, it also brings the difficulty of removal, which usually leads to the selection of not removing the floor slab change bracing in most cases during the construction process.
[0003] The decision of not removing the floor slab change bracing simplifies the construction process, but it has an adverse effect on the waterproof construction of the basement. Because the floor slab change bracing is poured into a whole with the outer wall and the fender pile structure, the continuity of the waterproof layer is interrupted, which increases the risk of basement water seepage. In addition, this method also leads to the waste of building materials, because once the floor slab change bracing becomes a permanent structure, the related materials cannot be recycled. SUMMARY

[0039] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described in the following with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.
[0040] The embodiments of the utility model will be described below with reference to the drawings. Figures 1 to 4
[0041] According to the embodiments of the utility model, on the one hand, a middle floor bracing plate belt structure is provided for supporting the fender pile 100 and the outer wall 200 in the horizontal direction. The middle floor bracing plate belt structure comprises a floor bracing main body 1, a plurality of connecting hanging bars 2 and a connecting assembly 3. One end of the floor bracing main body 1 is connected with the fender pile 100, and the other end is connected with the outer wall 200. One end of the connecting hanging bar 2 is connected with the fender pile 100, and the other end is connected with the floor bracing main body 1. The connecting assembly 3 is arranged between the floor bracing main body 1 and the outer wall 200.
[0042] In the middle floor bracing plate belt structure provided in the embodiments, one end of the floor bracing main body 1 is connected with the fender pile 100 through the connecting hanging bar 2, the connecting hanging bar 2 can strengthen the connection strength between the floor bracing main body 1 and the fender pile 100, and the other end is connected with the outer wall 200 through the connecting assembly 3, so that the floor bracing main body 1 and the outer wall 200 do not need to be planted with a reinforcing bar, and thus the floor bracing main body 1 and the outer wall 200 are still two separate structures, rather than an integrated structure. Therefore, after the construction is completed, the connection between the floor bracing main body 1 and the outer wall 200 and the fender pile 100 can be cut off by cutting off the connecting hanging bar 2 and the connecting piece, the construction difficulty is greatly reduced, the floor bracing main body 1 can be easily removed, the continuity of waterproof is avoided from being damaged, and the material of the floor bracing belt can be recycled, which is green construction.
[0043] It should be noted that there is still a connection between the floor bracing main body 1 and the fender pile 100, but the connection mode is relatively weak, and after the connecting hanging bar 2 is cut off, only a small external force needs to be applied to break the concrete connection between the floor bracing main body 1 and the fender pile 100. The connecting assembly 3 is arranged between the floor bracing main body 1 and the outer wall 200, so the connecting assembly 3 is exposed to the external environment, and only a conventional means is needed to cut off the connection between the connecting assembly 3 and the floor bracing and / or the outer wall 200, or to cut the connecting assembly 3 into two parts, and the cutting mode is simple.
[0044] In the embodiment, the number of the connecting suspender 2 is not limited, and the number of the connecting suspender 2 should be set according to the size of the floor bracing body 1. The connecting suspenders 2 are arranged in parallel and at intervals, so as to ensure the connection strength of the connecting suspenders 2 to the floor bracing body 1 as a whole.
[0045] In one embodiment, the connecting assembly 3 comprises a first connecting piece 31 and a second connecting piece 32. The first connecting piece 31 is connected with the floor bracing body 1, and the second connecting piece 32 is connected with the outer wall 200. The first connecting piece 31 is detachably connected with the second connecting piece 32. The floor bracing body 1 and the outer wall 200 are connected through the first connecting piece 31 and the second connecting piece 32. Since the first connecting piece 31 is detachably connected with the second connecting piece 32, the connection between the first connecting piece 31 and the second connecting piece 32 is disconnected, and the connection between the floor bracing body 1 and the outer wall 200 is disconnected, so that the construction difficulty is effectively reduced.
[0046] In one embodiment, the first connecting piece 31 comprises a first body 311 and a plurality of first connecting rods 312. The first connecting rods 312 are arranged in the floor bracing body 1. The first body 311 is arranged at one end of the floor bracing body 1 close to the outer wall 200, and the first connecting rods 312 are connected with the first body 311. The second connecting piece 32 comprises a second body 321 and a plurality of second connecting rods 322. The second connecting rods 322 are arranged in the outer wall 200. The second body 321 is arranged at one side of the outer wall 200 close to the floor bracing body, and the second connecting rods 322 are connected with the second body 321. The first body 311 is detachably connected with the second body 321. The first connecting rods 312 connect the first body 311 and the floor bracing body 1, so as to increase the connection strength between the first body 311 and the floor bracing body 1. The second connecting rods 322 connect the second body 321 and the outer wall 200, so as to increase the connection strength between the second body 321 and the outer wall 200. The connection strength between the second body 321 and the outer wall 200 can effectively transmit the horizontal force borne by the enclosure pile 100 during construction. The detachable connection between the first body 311 and the second body 321 can effectively reduce the difficulty of disassembly.
[0047] In other embodiments, as shown in Figure 2 The end of the second connecting rod 322 close to the middle floor 300 can extend into the middle floor 300, so as to strengthen the connection strength between the second connecting piece 32 and the outer wall 200, and avoid the falling of the second connecting piece 32.
[0048] In one embodiment, the outer wall 200 is vertically provided with a middle floor 300 away from one side of the floor bracing body 1, and a plurality of second connecting rods 322 are arranged in the middle floor 300 within the projection range of the outer wall 200. Through the arrangement, the horizontal force borne by the enclosure pile 100 can be more effectively transmitted to the middle floor 300 through the floor bracing body 1, so as to avoid damage to the enclosure or the outer wall 200, and ensure construction safety.
[0049] In one embodiment, the end surface area of the end of the floor bracing body 1 connected with the first body 311 is smaller than the area of the side of the first body 311 close to the floor bracing body 1. Through the above arrangement, the connection strength of the first body 311 and the bracing floor body 1 can be effectively increased, and the outer peripheral contour of the first body 311 can be protruded from the outer peripheral contour of the floor bracing body 1, so as to facilitate cutting of the first body 311 and the second body 321.
[0050] In one embodiment, the thickness of the floor bracing body 1 is greater than or equal to the thickness of the middle floor 300. The structural strength of the floor bracing body 1 can be increased, so as to ensure the supporting effect on the outer wall 200 and the enclosure pile 100.
[0051] In one embodiment, the first body 311 and the second body 321 are connected by welding. The connection mode is simple and firm, and the connection between the first body 311 and the second body 321 can be cut off by a conventional mode, so as to ensure the supporting effect and the demolishability of the middle floor 300 bracing structure.
[0052] It should be noted that the welding is usually performed along the joint between the first body 311 and the second body 321, and in the embodiment, the welding seam can be cut by a cutting machine or the like cutting equipment, so as to reduce the cutting difficulty and the construction difficulty.
[0053] In one embodiment, the end of the connecting hanging bar 2 connected with the enclosure pile 100 is bent to one side to form a first extension section 21, and the extension direction of the first extension section 21 is parallel to the height direction of the enclosure pile 100. The end of the connecting hanging bar 2 connected with the enclosure pile 100 can be prevented from being inserted too deep into the enclosure pile 100, so as to avoid damage to the structural strength of the enclosure pile 100 and interference with the steel bars in the enclosure pile 100.
[0054] In one embodiment, the end of the connecting hanging bar 2 connected with the floor bracing body 1 is bent to one side to form a second extension section 22, and the extension direction of the second extension section 22 is parallel to the length direction A of the floor bracing body 1. Through the second extension section 22, the connection strength between the connecting hanging bar 2 and the floor bracing body 1 can be increased, the ability of the connecting hanging bar 2 to resist the gravity of the floor bracing body 1 in the vertical direction can be enhanced, and the connection strength between the connecting hanging bar 2 and the floor bracing body 1 can be ensured.
[0055] It should be noted that the length direction A of the floor bracing body 1 is perpendicular to the outer wall 200 in the cross-sectional view. Figure 1 Figure 1 The length direction A of the floor bracing body 1 is perpendicular to the outer wall 200 in the cross-sectional view.
[0056] In one embodiment, the floor bracing plate belt structure further comprises a lifting ring 4 arranged on the top surface of the floor bracing body 1. By arranging the lifting ring 4, after cutting off the connection between the floor bracing body 1 and the enclosure pile 100 and the outer wall 200, the lifting ring 4 can be connected with a lifting device, so that the lifting device hoists the floor bracing body 1, thereby reducing the construction difficulty.
[0057] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the appended claims.
