Description

Technical Field

[0001] The invention relates to the field of steel structures, in particular to a multi-section steel structure adapted to an inclined surface. Background Art

[0002] Steel structure refers to the load-bearing component that contacts the foundation at the bottom of the building. It is the lower extension of the structure that directly contacts the foundation to transfer the load. Its function is to transfer the load of the upper part of the building to the foundation. Therefore, the foundation must be strong, stable and reliable. At present, when installing the reinforcement rod of the existing inclined steel structure, it is generally fixed by tightening the steel wire, which has low work efficiency, makes the fixation unstable, and the reinforcement rod is easy to deviate. There is a problem that it is not convenient to combine and fix the reinforcement rod. Therefore, we propose a inclined steel structure to solve the above problems. Summary of the invention

[0003] The present invention provides a multi-section steel structure adapted to an inclined surface, which overcomes the deficiencies described in the background art.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] A multi-section steel structure adapted to an inclined surface comprises a multi-section steel body, a fixing mechanism, and a connecting and fixing tube body, wherein the connecting and fixing tube body is fixed to the multi-section steel body by the fixing mechanism, a plurality of deformation slits are arranged on the upper and lower surfaces of the multi-section steel body, and the deformation slits on the upper and lower sides are arranged at intervals, and the connecting and fixing tube body is arranged between the two deformation slits; the deformation slits connect the inner and outer ends of the multi-section steel body, and each deformation slit is closed by a closing plate, the side surface of the closing plate protrudes outward, and the deformation slit has a corresponding slot, and the closing plate is clamped on the deformation slit through the slot.

[0006] A better technical solution: the fixing mechanism includes bolts, oblique fixing parts, and abutment locking strips. The oblique fixing parts are connected to the two sides of the connecting and fixing tube body by bolts, and the two oblique fixing parts are connected by abutment locking strips. The cross-section of the deformation seam is bent, and the abutment locking strips are arranged on the surface of the deformation seam.

[0007] A preferred technical solution: the oblique fixing piece and the surface of the connecting and fixing tube body both have coaxially arranged threaded holes, and the bolts are respectively passed through the two threaded holes to fix the oblique fixing piece on the connecting and fixing tube body.

[0008] A preferred technical solution: a plurality of locking blocks are provided on the side of the oblique fixing member facing the multi-section steel body, the edge of the locking block forms an angle with the edge of the multi-section steel body, the side surface of the multi-section steel body has a corresponding notch, and the locking blocks of the oblique fixing member are inserted into the notch and abut against the inner side surface of the notch.

[0009] A preferred technical solution: A plurality of Z-shaped reinforcing ribs are further provided in the multi-segment steel body, wherein the Z-shaped reinforcing ribs are provided between the two deformation seams, and the upper and lower ends of the Z-shaped reinforcing ribs are both against the upper and lower ends of the inner side of the multi-segment steel body;

[0010] A preferred technical solution: the connecting end between the Z-shaped reinforcement rib and the extension part has an angled groove, and the Z-shaped reinforcement rib is provided with a first reinforcement part and a second reinforcement part, the first reinforcement part and the second reinforcement part are respectively arranged on the surfaces of the Z-shaped reinforcement rib and the extension part, the first reinforcement part is closer to the angled groove than the second reinforcement part, and the distance difference between the two is greater than the width of the first reinforcement part.

[0011] Compared with the background technology, this technical solution has the following advantages:

[0012] Since the cross-section of the deformation seam is bent, when the abutment and locking strip is against its surface and the connected fixed tube body slides laterally, the abutment and locking strip is subjected to force to squeeze the deformation seam downward, but cannot detach from the deformation seam. In addition, the design of inserting the oblique fixing part into the groove can also allow the received pressure to be evenly distributed on the multi-section steel body, thereby preventing the abutment and locking strip from receiving a large extrusion force.

[0019] In the figure: a multi-section steel body 1, a deformation seam 11, a closing plate 12, a notch 13, a Z-shaped reinforcement rib 14, a first reinforcement part 141, a second reinforcement part 142, a fixing mechanism 2, a bolt 21, an oblique fixing member 22, abutting locking strip 23, and a connecting and fixing tube body 3. DETAILED DESCRIPTION

[0020] like Figure 1-5As shown, the multi-section steel structure adapted to the inclined surface comprises a multi-section steel body 1, a fixing mechanism 2, and a connecting fixing tube body 3, wherein the connecting fixing tube body 3 is fixed to the multi-section steel body 1 through the fixing mechanism 2, and a plurality of deformation slits 11 are provided on the upper and lower surfaces of the multi-section steel body 1, and the deformation slits 11 on the upper and lower sides are arranged at intervals, and the connecting fixing tube body 3 is arranged between two deformation slits 11; the deformation slits 11 connect the inner and outer ends of the multi-section steel body 1, and each deformation slit 11 is closed by a closing plate 12, and the closing plate 12 is provided to close the deformation slits 11. The side of the plate 12 protrudes outward, and the deformation seam 11 has a corresponding slot, and the closing plate 12 is clamped on the deformation seam 11 through the slot. The function of the present invention is to fix connecting parts, steel bars, plates, etc. on the inclined surface. A steel structure is designed. When in use, the object to be fixed needs to be placed in the connecting and fixing pipe body 3 and erected to form a longitudinal limit. If a lateral limit is required, the operator needs to drill holes on the surface of the connecting and fixing pipe body 3, and fix the object to be fixed by bolting or rivets to form a lateral limit.

[0021] The multi-section steel body 1 is fixed on supports such as buildings and steel bars. Therefore, after the fixed pipe body 3 is connected to the supported object, the multi-section steel body 1 needs to cooperate with it to install the supported object on an inclined surface. In order to enable the multi-section steel body 1 to adapt to supports with different inclined surfaces, multiple deformation seams 11 are provided on the upper and lower sides of the multi-section steel body 1. The function of the deformation seams 11 is to facilitate the bending of the multi-section steel body 1, so that the multi-section steel body 1 bends along the contour of the support, and the deformation seams 11 can be used as a track. , use a cutting machine to enlarge the deformation seam 11 so that the inner side of the multi-segment steel body 1 can better fit against the support. On the contrary, since the deformation seam 11 can be clamped by the closing plate 12, in order to improve the fixity of the multi-segment steel body 1 during use, the multi-segment steel body 1 can be filled with concrete. In order to avoid a large amount of concrete overflow, the closing plate 12 can be embedded in the deformation seam 11 to block the opening of the deformation seam 11 after adjusting the angle and contour of the multi-segment steel body 1, and then the concrete can be poured into the multi-segment steel body 1 for casting and molding.

[0022] Furthermore, in order to improve the fixation of the fixing mechanism 2, the fixing mechanism 2 includes a bolt 21, an oblique fixing piece 22, and an abutting locking strip 23. The oblique fixing piece 22 is connected to both sides of the connecting and fixing tube body 3 by the bolt 21, and the two oblique fixing pieces 22 are connected by the abutting locking strip 23. The cross section of the deformation seam 11 is bent, and the abutting locking strip 23 is arranged on the surface of the deformation seam 11. This arrangement is to limit the lateral sliding of the connecting and fixing tube body 3. To form an abutment, since the cross-section of the deformation seam 11 is bent, when the abutment locking strip 23 is abutted against its surface and the connected fixed tube body 3 slides laterally, the abutment locking strip 23 is forced to squeeze the deformation seam 11 downward, but cannot detach from the deformation seam 11, and the oblique fixing member 22 will also distribute the force evenly to prevent the abutment locking strip 23 from receiving a large extrusion force. Therefore, it can be understood that the abutment locking strip 23 exists as a locking member, and it is not just a structure as shown in the figure, as long as it plays the function of locking and connecting the two oblique fixing members 22.

[0023] Furthermore, the oblique fixing member 22 and the surface of the connecting and fixing tube body 3 both have coaxially arranged threaded holes, and the bolts 21 respectively penetrate through the two threaded holes to fix the oblique fixing member 22 on the connecting and fixing tube body 3 .

[0024] In order to enable the oblique fixing member 22 to more intuitively and directly support, lock and fix the connecting and fixing pipe body 3, the oblique fixing member 22 in the present invention is provided with a plurality of locking blocks on the side facing the multi-segment steel body 1, and the edge of the locking block has an angle with the edge of the multi-segment steel body 1, and the side of the multi-segment steel body 1 has a corresponding notch 13, and the locking block of the oblique fixing member 22 is inserted into the notch 13 and abuts against the inner side of the notch 13, so that the connecting and fixing pipe body 3 can be fixed under stress through the angle design of the notch 13. When force is applied downward along the inclined surface of the multi-section steel body 1, it is prevented from sliding. In order to facilitate subsequent disassembly, if the multi-section steel body 1 is reinforced by pouring concrete, when pouring, the operator needs to make a model that is the same as the oblique fixing piece 22, and then insert the model into the groove 13 to pour cement. This arrangement is to form a groove on the surface of the concrete for inserting the oblique fixing piece 22 after the concrete is cooled and solidified, so as to avoid the problem that the oblique fixing piece 22 is fixed to the concrete after being directly inserted and cannot be disassembled.

[0025] Furthermore, a plurality of Z-shaped reinforcing ribs 14 are further provided in the multi-segment steel body 1, and the Z-shaped reinforcing ribs 14 are provided between the two deformation seams 11, and the upper and lower ends of the Z-shaped reinforcing ribs 14 are both against the upper and lower ends of the inner side of the multi-segment steel body 1, and the Z-shaped reinforcing ribs 14 are mainly used to improve the strength of the multi-segment steel body 1 and act as reinforcing ribs, and when a heavier object is fixed to the connecting and fixing tube body 3, the multi-segment steel body 1 is easily bent with the deformation seam 11 as a fulcrum, and the Z-shaped reinforcing ribs 14 will also be twisted, increasing the pressure required for bending the multi-segment steel body 1 and improving the strength of the multi-segment steel body 1, and the Z-shaped reinforcing ribs 14 and the connecting end of the extension part have a An angled groove is formed, and a first reinforcing portion 141 and a second reinforcing portion 142 are provided on the Z-shaped reinforcing rib 14. The first reinforcing portion 141 and the second reinforcing portion 142 are respectively provided on the surfaces of the Z-shaped reinforcing rib 14 and the extension portion. The first reinforcing portion 141 is closer to the angled groove than the second reinforcing portion 142, and the distance between the two is greater than the width of the first reinforcing portion 141. When the multi-section steel body 1 is bent to the point where the first reinforcing portion 141 and the second reinforcing portion 142 intersect, the side surface of the first reinforcing portion 141 will rub against the second reinforcing portion 142 and respectively abut against the surfaces of the Z-shaped reinforcing rib 14 opposite thereto, thereby avoiding deformation of the Z-shaped reinforcing rib 14 again.

[0026] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
