Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building structure design in the fields of rail transit, industry and civil architecture, and particularly relates to a crack separating structure between a structural wall and a non-structural wall. Background Art
[0002] At present, the common crack separating design method between a structural wall and a non-structural wall is to set small-sized polystyrene boards to achieve the purpose of force division. However, due to the small strength, poor durability and great construction control difficulty of the polystyrene boards themselves, the polystyrene boards are prone to breakage or displacement, thus affecting the function of the crack separating structure in dividing the forces of the structural wall and the non-structural wall, increasing the force on the original designed structural wall and causing potential structural safety hazards. Content of the Utility Model
[0003] The purpose of the utility model is to provide a crack separating structure between a structural wall and a non-structural wall to solve the above-mentioned defects existing in the existing crack separating design method.
[0004] To solve the above technical problems, the utility model provides a crack separating structure between a structural wall and a non-structural wall, which is characterized by comprising a structural shear wall, a non-structural cast-in-place wall, short connecting steel bars and a separating pipe. There is a crack separating between the structural shear wall and the non-structural cast-in-place wall. The structural shear wall and the non-structural cast-in-place wall are connected by short connecting steel bars at the crack separating, and the separating pipe is arranged in the crack separating between the structural shear wall and the non-structural cast-in-place wall.
[0005] Preferably, there are multiple short connecting steel bars which are evenly distributed along the direction of the crack separating.
[0006] Preferably, the short connecting steel bars are arranged in multiple rows in the thickness direction of the non-structural cast-in-place wall.
[0007] Preferably, the separating pipe is arranged along the direction of the crack separating, the number of the separating pipes is the same as the number of rows of the short connecting steel bars, and the position of one separating pipe corresponds to the position of one row of short connecting steel bars.
[0008] Preferably, the intersection of the separating pipe and the corresponding short connecting steel bar is fixed by tying with soft steel wires.
[0009] Preferably, there are two rows of short connecting steel bars.
[0010] Preferably, the separating pipe is made of PVC material.
[0011] Preferably, concrete is poured into the crack separating between the structural shear wall and the non-structural cast-in-place wall.
[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0013] The utility model can achieve cracking at the connection position between the structural wall and the non-structural wall under the action of an earthquake, so that the structural wall and the non-structural wall are separated, without increasing the overall force on the structural wall. A PVC separation pipe is arranged between the structural wall and the non-structural wall, which plays a role in separating the forces of the structural and non-structural walls. By using a small-diameter PVC separation pipe, the possibility of cracks appearing at the connection can be effectively reduced. Setting two PVC pipes has a better effect. When one pipe fails, the other pipe can still play a role, having a certain safety redundancy. At the same time, due to the relatively high strength, good durability and easy construction positioning control of the PVC separation pipe itself, the actual effect of the post-construction tension joint can be guaranteed, meeting the integrity requirements under construction load and conventional load. In addition, during construction, the PVC pipe is connected and fixed to the adjacent structural vertical or horizontal stressed steel bars through soft steel wires, making the positions of the PVC pipe and the short connecting steel bars more stable and not prone to displacement. The utility model is beneficial to more effectively exert the actual role of the tension joint, better meet the relevant requirements of the structure and building functions under conventional load and earthquake action, and ensure the structural safety.

[0019] The following further describes in detail the embodiments of the utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model, but cannot be used to limit the scope of the utility model.
[0020] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model. Unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, in the description of the present utility model, unless otherwise stated, the meaning of "a plurality of" is two or more.
[0021] As Figures 1 to 3 shown, the present utility model provides the following technical solution: a crack separating structure for a structural and non-structural wall, characterized in that it includes a structural shear wall 1, a non-structural cast-in-place wall 2, short connecting steel bars 4, and a separating pipe 3. The structural shear wall 1 is a concrete stress-bearing wall required by actual design, the non-structural cast-in-place wall 2 is made of concrete, and there is a crack 6 between the structural shear wall 1 and the non-structural cast-in-place wall 2.
[0022] The structural shear wall 1 and the non-structural cast-in-place wall 2 are connected by short connecting steel bars 4 at the crack 6. The short connecting steel bars 4 are perpendicular to the wall surfaces at the crack of the two walls. Specifically, there can be multiple short connecting steel bars 4, and the multiple short connecting steel bars 4 are evenly distributed along the crack direction. The short connecting steel bars 4 can be arranged in multiple rows in the thickness direction (perpendicular to the crack direction) of the non-structural cast-in-place wall 2. The length, diameter, and spacing of the short steel bars can be selected according to actual needs. In this embodiment, the diameter of the short steel bars is 6 mm, the length is 400 mm, and the spacing is 600 mm.
[0023] The separating pipe 3 with a tubular structure is easy to position and control during construction. The separating pipe 3 is arranged in the crack 6 between the structural shear wall 1 and the non-structural cast-in-place wall 2 and is parallel to the wall surface of the non-structural cast-in-place wall 2. The separating pipe 3 is arranged along the crack direction. The number of the separating pipes 3 can be the same as the number of rows of the short connecting steel bars 4. The separating pipe 3 can be located inside the short connecting steel bars 4. As Figure 4As shown, the intersection of the partition pipe 3 and the short connecting steel bar 4 is tied and fixed with a soft steel wire 5, making the positions of the partition pipe 3 and the short connecting steel bar 4 more stable and not prone to displacement. In this embodiment, there are two rows of short connecting steel bars 4 and two partition pipes 3. The setting of the two partition pipes can better achieve the function of the expansion joint: when one partition pipe fails, the other partition pipe can still play a role, having a certain safety redundancy. The partition pipes can have different diameters. In this embodiment, the diameter is 35mm. Using a small diameter instead of a large diameter can effectively reduce the possibility of cracks appearing at the connection.
[0024] The partition pipe 3 is preferably made of PVC material. The PVC partition pipe has relatively high self-strength and good durability, and steel pipes can also be used according to actual needs.
[0025] Concrete is poured into the expansion joint 6 between the structural shear wall 1 and the non-structural cast-in-place wall 2.
[0026] The utility model can cause the connection position between the structural wall and the non-structural wall to crack under the action of an earthquake, so that the structural wall and the non-structural wall are separated, without increasing the overall stress of the structural wall. By setting a PVC partition pipe between the structural wall and the non-structural wall, it plays a role in separating the forces of the structural and non-structural walls. Using a small-diameter PVC partition pipe can effectively reduce the possibility of cracks appearing at the connection. Setting two PVC pipes has a better effect. When one pipe fails, the other pipe can still play a role, having a certain safety redundancy. At the same time, because the PVC partition pipe has relatively high self-strength, good durability and is easy to position and control during construction, it can ensure that the expansion joint plays an actual role after construction, meeting the integrity requirements under construction load and conventional load. In addition, during construction, the PVC pipe is connected and fixed to the adjacent structural vertical or horizontal stressed steel bars through a soft steel wire, making the positions of the PVC pipe and the short connecting steel bar more stable and not prone to displacement. The utility model is beneficial to more effectively playing the actual role of the expansion joint, better meeting the relevant requirements of the structure and building functions under conventional load and earthquake action, and ensuring structural safety.
[0027] The embodiments of the present utility model are given for purposes of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles of the present utility model and its practical applications, and to enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.
