Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a temporary road free-top-return structure for a basement top plate. Background Art
[0002] With the process of urbanization, land resources are in short supply, and underground space is being deeply developed. There are more and more deep and large foundation pit construction projects. For some developers, in order to ensure full utilization of the land within the red line, the basement foundation pit edge is close to the land red line. After the basement structure is completed, there is no temporary road for the ground structure construction, and the entry of ground structure materials will be severely restricted. Using the basement top plate as a temporary road often requires the use of steel pipes, wooden squares and other materials in the basement to return to the top to ensure the safety of the top plate load and prevent the top plate from cracking and leaking after traffic is opened. This conventional solution seriously wastes the rental of turnover materials such as steel pipes and seriously affects the basement construction. In addition, for deep foundation pits with many basement floors, it is necessary to return to the bottom plate, which is even more inconvenient for returning to the top construction, and further affects the comprehensive electromechanical and secondary structure construction of the basement.

[0012] The technical solution of the utility model is described in detail below with reference to the accompanying drawings, but the protection scope of the utility model is not limited to the embodiments.
[0013] Reference Figure 1 The utility model discloses a temporary road structure without top return on the basement roof, comprising a frame column and a basement roof located above the frame column, a steel section is arranged above the basement roof, the steel section comprises a vertical steel section and a horizontal steel section located between the vertical steel sections, a steel structure road plate is arranged above the horizontal steel section, the road plate is fixedly connected to the horizontal steel section, the vertical steel section is fixedly connected to the basement roof, and guardrails are arranged on both sides of the road plate. In the utility model, iron plate embedded parts are embedded in the vertices and main beam areas of the frame columns, the iron plate embedded parts are fixed by anchor bars, the bottom of the vertical steel section is welded and fixed to the embedded parts, and the height of the vertical steel section is 0.2-0.3 meters.
[0014] Preferably, bolt holes are reserved on the horizontal steel section, and the track plate is fixedly connected to the horizontal steel section by screws and bolts.
[0015] The construction method of the utility model is as follows:
[0016] To deepen the drawings, it is necessary to make a temporary road area on the basement roof, calculate the stress conditions of the beams and columns in advance, increase the reinforcement appropriately, meet the traffic load requirements of the temporary road area, and ensure the strength and rigidity of the beams and columns.
[0017] Measure and lay out in the temporary road area, embed iron plates and embedded parts in advance to ensure the accuracy of the position. After the concrete pouring of the basement top slab is completed and reaches the design strength, weld the vertical steel sections. The welding process ensures the welding quality and verticality requirements. The height of the vertical steel sections is designed to be 0.2-0.3 meters.
[0018] After the vertical steel keel is welded, the horizontal steel keel is welded. All horizontal directions require welding. Pay attention to the welding quality and welding flatness during the welding process. Vertical and horizontal welding mainly ensures the rigidity and stability of the keel.
[0019] The horizontal and vertical steel sections are welded with diagonal keels to ensure the overall strength and rigidity, and the welds must also maintain the corresponding thickness and fullness.
[0020] A steel structure box-type slab is laid on top of the horizontal steel keel. Connection parts are reserved on both sides of the box-type slab and connected to the horizontal steel. Screws and bolts are used for easy dismantling. Each slab is laid with tight joints on both sides to ensure horizontality.
[0021] After the slab is laid, temporary guardrails are installed on both sides of the slab. The height of the guardrails meets the safety regulations. The guardrails are also connected to the slab with bolts for easy disassembly.
[0022] The utility model mainly solves the problem of temporary road access on the top plate, and adopts a steel structure on site to avoid direct contact between passing vehicles and the top plate, thereby ensuring the quality of the basement top plate.
[0023] There is no need to reinforce the bottom of the basement roof with circulating materials such as steel pipes and wood, which saves related construction costs and material rental.
[0024] The basement does not need to be rebuilt, which ensures effective space for subsequent construction of the basement and guarantees the construction progress of the comprehensive mechanical and electrical and rough decoration of the basement secondary structure.
[0025] A construction method adapted to local conditions was implemented, using steel support structure plus steel structure road slab, which is convenient for construction and connection, and there is no need for vehicles to pass directly on the basement roof. This construction method pre-buries iron plate embedded parts in advance and uses steel structure road slab for laying. Later, vehicles can pass directly on the road slab, which is convenient, fast, safe, environmentally friendly and cost-saving.
[0026] As above, although the utility model has been shown and described with reference to a specific preferred embodiment, it should not be interpreted as limiting the utility model itself. Various changes can be made to it in form and detail without departing from the spirit and scope of the utility model defined in the attached claims.
