Description
Technical Field
[0001] The utility model belongs to the field of cable trench equipment support, in particular to an indoor cable trench equipment embedded component support building structure. Background Art
[0002] At present, both industrial and civil construction projects need to lay electrical pipelines indoors and configure various high-voltage and low-voltage frequency conversion electrical cabinets to meet people's electricity needs. The electrical pipelines laid in the cable trench need to be connected to the electrical cabinets. At present, the ground building structures here use different materials and methods. A common problem is that the supporting wall set vertically at the bottom of the electrical cabinet has a hole for passing the electrical pipeline, which causes insufficient bearing capacity, resulting in uneven settlement, and ultimately damages the electrical equipment, causing economic losses to the user.
[0003] In view of the shortcomings of the above-mentioned technologies, there is an urgent need for a supporting building structure that takes into account the use requirements, structure and construction convenience to achieve the stable fixation of electrical cabinet equipment.

[0014] The inner surface of the cable trench wall is provided with a trench wall surface layer.
[0015] The trench wall surface layer at both the beam end and the beam center extends until it is flush with the upper surface of the combined embedded support beam in the trench.

The cover plate support embedded ribs are C-shaped, with their heads fixedly connected to the inner side of the cover plate support edge angle steel, their two limbs are straight, and their feet are bent.
[0018] The cover plate support edge angle steel of the cover plate support is relatively convex, and the embedded component where the cover plate support is located forms an upward convex body at the position of the cover plate support edge angle steel, so that the cover plate support and the upper surface of the embedded component are formed with a height difference.
[0019] The equipment support is composed of an equipment support embedded plate and an equipment support embedded rib. The equipment support embedded plate is horizontally arranged, and its upper surface is flush with the upper surface of the embedded component.

[0026] The cable trench structure of the utility model is a connected main trench and branch trench, and the cable trench wall on the connecting side of the vertical intersection between the main trench and the branch trench is eliminated, so as to avoid opening holes for passing electrical pipelines on the supporting wall arranged at the bottom of the electrical cabinet equipment. The connecting space between the main trench and the branch trench is large, and there is no wall to block, so it is convenient to access the electrical pipelines from below.
[0027] The utility model also provides a combined embedded support beam in the trench, and overlaps its two ends at the positive corner of the trench wall at the connection position between the main trench and the branch trench, and pre-buries the equipment support component combination in the support beam. In cooperation with the equipment support component outside the trench, the two ends of the combined embedded support beam in the trench can transfer the load of the electrical cabinet equipment to the positive corner of the trench wall at both ends, and then to the trench wall, and finally to the foundation. At the same time, the beam of the combined embedded support beam in the trench is directly supported by the pier wall arranged laterally to divide the branch trench, and the load in the beam is transferred to the pier wall and then to the foundation. The force distribution is more reasonable, ensuring that there is no settlement below the position of the electrical cabinet equipment, and can effectively achieve the fixation and stability of the electrical cabinet equipment.
[0028] The utility model also pre-buries a cover plate support in the combined embedded support beam in the trench, which cooperates with the cover plate support outside the trench. The cover plate structure is overlapped on the cover plate support in the beam at the support beam position, so that the cable trench under the electrical cabinet equipment can be tightly sealed to prevent dust from falling into the cable trench from the junction of the main cable trench and the branch cable trench.
[0029] The combined embedded supporting beam in the trench of the utility model is a prefabricated reinforced concrete part, which is easy to construct and has two kinds of prefabricated embedded parts built in, including a cover plate support and an equipment support part. The supporting beam forms a building structure that can simultaneously support electrical cabinet equipment and cable trench cover plates. BRIEF DESCRIPTION OF THE DRAWINGS
