Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, specifically a construction system for simultaneously casting perforated inverted beams with formwork support. Background Technology

[0002] Currently, when strip beam foundations, bathroom curbs (reverse edges), and floor slab concrete are constructed simultaneously, tie rods are typically used for formwork. However, tie rod formwork presents the following risks:

[0003] 1. Risk of waterproofing failure

[0004] Leakage channel formation: PVC sleeves need to be pre-embedded for the tie rods to allow for reuse, but the contact surface between the sleeve and the concrete is prone to forming a through-seepage channel. The core function of the bathroom curb is to block water seepage, and any hole may lead to waterproofing failure.

[0005] Uncontrollable sealing quality: The holes left after the screw is removed need to be sealed again, but manual filling with mortar is prone to hollowing or shrinkage cracks (a hollowing rate of >5% may lead to leakage).

[0006] 2. Structural performance defects

[0007] Weakening the integrity of concrete: Perforation of tie rods disrupts the continuity of the cross-section of the inverted curb, reducing its crack resistance; while a one-time cast inverted curb without joints can significantly improve the structure's self-waterproofing ability.

[0008] Load transfer obstructed: The bolt hole affects the stress transfer between the curb and the floor slab, which may cause stress concentration at the root and increase the risk of cracking.

[0009] The information disclosed in the above background section is only intended to enhance the understanding of the overall background of this utility model, and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art. Utility Model Content

[0010] To address the aforementioned shortcomings, the present invention aims to provide a construction system for simultaneously casting perforated inverted beams without perforating the beams or installing tie rods, thereby avoiding defects such as waterproofing failure and obstructed load transfer.

[0011] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] A construction system for simultaneously casting perforated inverted beams includes parallel vertically arranged left and right wooden formwork. The upper and lower ends of the left side of the left wooden formwork abut against the upper and lower left steel plates, which are respectively connected to the upper and lower ends of a left vertical telescopic adjustable screw rod. The upper and lower ends of the right side of the right wooden formwork abut against the upper and lower right steel plates, which are respectively connected to the upper and lower ends of a right vertical telescopic adjustable screw rod. The system also includes a horizontal telescopic adjustable screw rod, which is horizontally arranged above the left and right wooden formwork. The left end of the horizontal telescopic adjustable screw rod extends to the left and beyond the left vertical telescopic adjustable screw rod, then extends downward and is fixedly connected to the left vertical telescopic adjustable screw rod. The right end of the horizontal telescopic adjustable screw rod extends to the right and beyond the right vertical telescopic adjustable screw rod, then extends downward to the bottom end of the right vertical telescopic adjustable screw rod and is fixedly connected to the right vertical telescopic adjustable screw rod.

[0013] Furthermore, the horizontal telescopic adjustable screw rod, the left upper steel plate, the left lower steel plate, the left vertical telescopic adjustable screw rod, the right upper steel plate, the right lower steel plate, and the right vertical telescopic adjustable screw rod are arranged in sets, with more than 3 sets, and are evenly arranged between the longitudinal ends of the left and right wooden templates.

[0014] Furthermore, a hollow adjustable nut is provided in the middle of the lateral telescopic adjustable lead screw.

[0015] Furthermore, the lateral telescopic adjustable lead screw is equipped with an adjustment scale.

[0016] Furthermore, adjustment scales are also provided on the left and right vertical telescopic adjustable lead screws.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention utilizes telescopic and adjustable horizontal and vertical lead screws, allowing the formwork system to be flexibly adjusted according to the dimensions of the inverted beam. This makes the formwork system more convenient to use and has a wider range of applications. Furthermore, since it eliminates the need to perforate the inverted beam, it avoids defects such as waterproofing failure and load transfer obstruction, resulting in superior waterproofing and crack resistance.
