Description

Technical Field

[0001] The utility model belongs to the technical field of stepped buildings and relates to an anti-settlement structure for outdoor steps. Background Art

[0002] With the development of society, there are more and more housing buildings. Some main buildings of housing buildings are higher than the ground, which requires the installation of outdoor steps in front of the main building to meet the needs of users to enter and exit.

[0003] The traditional installation method of outdoor steps is to directly install the outdoor steps on the ground. This installation method is suitable for the ground with relatively hard soil. At present, some housing buildings are built in coastal dredging and filling areas. Such areas have relatively soft soil layers such as soft soil and silt. After the main building and the outdoor steps are completed, they will all settle to a certain extent. However, due to the asynchronous settlement of the main building and the outdoor steps, there is a settlement difference, which leads to problems such as cracking and step dislocation at the connection between the outdoor steps and the main building. At the same time, the outdoor steps are also prone to cracking when built on relatively soft soil layers. Summary of the Invention

[0004] The purpose of the utility model is to solve the above problems existing in the prior art, and propose an anti-settlement structure for outdoor steps, and the technical problem to be solved is how to prevent the outdoor steps from cracking.

[0005] The purpose of the utility model can be achieved by the following technical solutions: An anti-settlement structure for outdoor steps, the outdoor steps include a plurality of step panels, side wall piers on both sides, and a plurality of spaced front wall piers between the two side wall piers. The step panels are fixedly connected to the tops of the side wall piers and the front wall piers in a stepped shape. The anti-settlement structure is characterized in that it includes a simple support plate, a support base fixedly connected to the main building, and a support foundation fixedly connected to the ground in front of the main building. The inner end of the simple support plate is fixedly connected to the support base, and the outer end is fixedly connected to the support foundation. Both of the two side wall piers and all of the front wall piers are fixedly connected to the simple support plate.

[0006] The support base of this anti-settlement structure is fixedly connected to the main building, and the support foundation is embedded in the ground in front of the main building. The support base and the support foundation settle synchronously with the main building. The two ends of the simple support plate are respectively fixedly connected to the support base and the support foundation. The outdoor steps are installed on the simple support plate. The support base, the support foundation and the simple support plate form a supporting structure for the outdoor steps, so that the outdoor steps settle synchronously with the main structure, and thus it is not easy for the outdoor steps to have common building engineering quality problems such as regional subsidence and cracking. The simple support plate has a certain strength and is not easy to deform, but it also has sufficient elasticity, which plays a good buffering role for the outdoor steps, makes the force deformation more gentle, makes the outdoor steps not easy to settle, and makes the outdoor steps not crack.

[0007] In the above-mentioned outdoor step anti-settlement structure, the cross-section of the bracket is a right triangle. The first right-angle surface of the bracket is fixedly connected to the main building. The inner end of the simply supported plate has a support portion protruding downward, and the support portion abuts against the second right-angle surface of the bracket. There is a rammed earth layer between the simply supported plate and the ground. This structure of the bracket plays a better role in connecting the main building and the simply supported plate. The setting of the rammed earth layer improves the bearing capacity, reduces the settlement of the outdoor steps, and prevents the outdoor steps from cracking. The height of the support portion can be about 30 cm, that is, the height of the rammed earth layer can be about 30 cm.

[0008] In the above-mentioned outdoor step anti-settlement structure, the bottom surface of the rammed earth layer and the second right-angle surface of the bracket are on the same horizontal plane. This structure enables the rammed earth layer to have better bearing capacity, reduces the settlement of the outdoor steps, and prevents the outdoor steps from cracking.

[0009] In the above-mentioned outdoor step anti-settlement structure, the top surface of the support foundation is higher than the second right-angle surface of the bracket, and the rammed earth layer is horizontally located between the support portion and the top of the support foundation. This structure enables the rammed earth layer to have better bearing capacity, reduces the settlement of the outdoor steps, and prevents the outdoor steps from cracking.

[0010] In the above-mentioned outdoor step anti-settlement structure, the support foundation includes a support block and several long straight rod-shaped support rods. The support block is fixedly connected to the top of the support rods, the outer end of the simply supported plate is fixedly connected to the support block, and the support rods are embedded in the ground. This structure enables the support foundation to better support the outdoor steps, reduces the settlement of the outdoor steps, and prevents the outdoor steps from cracking.

[0011] In the above-mentioned outdoor step anti-settlement structure, a first filling space is formed between the side wall pier, the front wall pier and the main building, and several second filling spaces are formed between the side wall pier and the front wall pier. The first filling space and the second filling spaces are both filled with lightweight concrete to form a filled concrete layer. This structure enables the outdoor steps to have sufficient strength and makes the outdoor steps not easily cracked. The filling of lightweight concrete reduces the weight of the outdoor steps, reduces the settlement of the outdoor steps, and prevents the outdoor steps from cracking.

[0012] In the above-mentioned outdoor step anti-settlement structure, a reinforced concrete layer is poured between the step panel and the filled concrete layer. The setting of the reinforced concrete layer improves the strength of the outdoor steps, enables the outdoor steps to better withstand pressure, and makes the outdoor steps not easily cracked and damaged.

[0013] In the above-mentioned outdoor step anti-settlement structure, the front wall pier and the side wall pier are perpendicular to each other, and both ends of all the front wall piers are fixedly connected to the side wall piers respectively. This kind of structure makes the outdoor step structure reasonable, enables the outdoor step to have sufficient strength, and makes the outdoor step not easy to crack and damage.

[0014] Compared with the prior art, the outdoor step anti-settlement structure provided by the present utility model has the following advantages:

[0015] 1. The drag seat, support foundation and simple support plate of this anti-settlement structure form a supporting structure for the outdoor step, enabling the outdoor step to settle synchronously with the main structure, and thus making it not easy for the outdoor step to have common building engineering quality problems such as regional settlement and cracking.

[0016] 2. The simple support plate of this anti-settlement structure has a certain strength and is not easy to deform, but also has sufficient elasticity, which plays a good buffering role for the outdoor step, makes the force deformation more gentle, makes the outdoor step not easy to settle, and makes the outdoor step not crack.
