Description

Technical Field

[0001] This utility model relates to the field of prefabricated building construction technology, specifically a UHPC formwork beam-lightweight partition wall panel integral installation structure. Background Technology

[0002] Currently, in the field of prefabricated building construction, the installation of lightweight partition walls generally adopts a segmented, single-panel hoisting method. Under this method, each panel needs to go through multiple processes such as positioning, hooking, lifting, alignment, and temporary support. The construction process is highly repetitive and complex, resulting in long working times for key equipment such as cranes, and significantly limiting the overall construction efficiency.

[0003] Traditional construction methods treat the installation of structural beams and the fixing of wall panels as two separate processes: the beams are installed first, and the wall panels are positioned and anchored only after the concrete strength reaches the design requirements. This step-by-step construction method not only causes delays due to the waiting period for the concrete curing of the beams, but also, due to the cumulative errors in each stage of construction, often results in the final installation accuracy of the wall panels failing to meet the specifications, leading to a low installation qualification rate and affecting the overall project quality. Especially when facing narrow working spaces such as corridors and passageways, existing technologies cannot achieve the synchronous hoisting of multiple lightweight partition wall panels in groups, nor can they solve the problem of integrated installation between structural beams and wall panel components, which seriously restricts the further improvement of the construction efficiency and industrialization level of prefabricated buildings. To address this, a UHPC formwork beam-lightweight partition wall panel integrated installation structure is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide an integral installation structure for UHPC molded beam-lightweight partition wall panel to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integral installation structure for a UHPC formwork beam-lightweight partition wall panel, comprising: Multiple partition walls are arranged in an array. UHPC formwork beams are installed on top of multiple partition wall panels; UHPC mold shell, set at the bottom of multiple partition walls; and Multiple connectors are installed on the UHPC formwork beams and / or the UHPC formwork, respectively. These connectors are connected to the partition wall panels to achieve an overall connection between the UHPC formwork beams, the UHPC formwork, and the partition wall panels.

[0006] As a further embodiment of this utility model: the bottom of the UHPC mold beam is provided with a tenon groove, and the top of the partition wall is provided with a tenon that matches the inside of the tenon groove.

[0007] As a further embodiment of this utility model: the top of the UHPC formwork beam is provided with a placement groove, and a reinforcing cage is provided in the placement groove.

[0008] As a further embodiment of this utility model: a tie rod is installed on the side of the UHPC formwork beam, and one end of the tie rod passes through the UHPC formwork beam and the reinforcing cage and is fitted with a fastener at its end.

[0009] As a further embodiment of this utility model: the UHPC mold shell is U-shaped with its opening facing the partition wall, the interior of the UHPC mold shell is adapted to the bottom of the partition wall, and multiple connectors on the side of the UHPC mold shell pass through the UHPC mold shell and are connected to its partition wall.

[0010] As a further embodiment of this utility model: the UHPC mold shell has two sets of connectors, which are respectively located on both sides of the UHPC mold shell, and each set of connectors consists of two connectors.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This application constructs a two-way mortise and tenon self-locking system by vertically inserting the UHPC formwork beam into the top of the partition wall panel and horizontally interlocking it with the UHPC formwork at the bottom of the partition wall panel. This system, combined with connectors on the UHPC formwork, achieves a factory-pre-assembled structure integrating the beam, wall, and formwork. This design upgrades the traditional discrete hoisting method for single wall panels to a modular hoisting method for multiple wall panels, significantly improving installation efficiency. Simultaneously, it avoids the beam curing waiting period and on-site anchoring procedures, effectively shortening the construction period of the critical path. Attached Figure Description

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-5 In this embodiment of the utility model, an integral installation structure of a UHPC formwork beam-lightweight partition wall panel includes: Multiple partition wall panels 1 are arranged in an array; UHPC formwork beam 2 is installed on top of multiple partition wall panels 1; UHPC mold shell 3, disposed at the bottom of multiple partition walls 1; and Multiple connectors 4 are installed on the UHPC formwork beam 2 and / or the UHPC formwork 3 respectively. The connectors 4 are connected to the partition wall 1 to achieve an overall connection between the UHPC formwork beam 2, the UHPC formwork 3 and the partition wall 1.

[0015] Specifically, the UHPC formwork beam 2 is prefabricated in a factory using ultra-high performance concrete and runs along the entire length of the building bay. The bottom of the UHPC formwork beam 2 has a tenon groove 21, with an elastic sealing strip pre-applied to the inner wall of the tenon groove 21. The partition wall panel 1 is an autoclaved aerated concrete (ALC) panel, and the top of the partition wall panel 1 has tenons 11 that fit into the tenon groove 21. Multiple tenons 11 on the top of the partition wall panels 1 are inserted into the tenon groove 21, causing the multiple partition wall panels 1 to form an array distribution under the action of the tenon groove 21. The connecting member 4 is a threaded rod. The number of threaded rods on the UHPC formwork beam 2 is not limited; in this embodiment, preferably, the number of threaded rods is two. Two threaded rods pass through the UHPC formwork beam 2 and connect to the two outermost partition walls 1 respectively to achieve load transfer. The UHPC formwork 3 is prefabricated in the factory using ultra-high performance concrete. It has an overall U-shaped structure with the opening facing the partition wall 1. The UHPC formwork 3 has a rubber buffer layer inside, and its inner cavity shape is adapted to the bottom of the partition wall 1. Multiple connectors 4 are set on the side of the UHPC formwork 3, pass through the wall of the UHPC formwork 3 and connect to the partition wall 1. The UHPC formwork 3 and the partition wall 1 are horizontally limited by the interlocking of the internal structure of the formwork and the bottom of the partition wall 1, thus forming a stable connection and positioning.

[0016] Through the above technical solutions, the UHPC formwork beam 2 forms a rigid load-bearing body through a high-performance concrete shell and an internal steel reinforcement skeleton, distributing the load of the upper structure laterally along the building; the UHPC formwork 3 provides a three-dimensional constraint base with a U-shaped structure, and its interior is horizontally interlocked with the bottom of the partition wall 1 to suppress displacement. The two achieve efficient vertical load transmission and horizontal limitation through a two-way tenon and mortise system, forming a stable nested structure of "upper support and lower support", which greatly improves the assembly accuracy and resistance to lateral pressure.

[0017] Please see Figure 2-3 In one embodiment, preferably, the top of the UHPC formwork beam 2 is provided with a placement groove 22, and a reinforcing cage 23 is provided in the placement groove 22. Further, the reinforcing cage 23 is composed of longitudinal main bars and stirrups, and the longitudinal bars are arranged along the entire length of the beam.

[0018] Please see Figure 3 In one embodiment, preferably, the UHPC formwork beam 2 is equipped with tie rods 24 on its side, and one end of the tie rod 24 passes through the UHPC formwork beam 2 and the reinforcing cage 23 and is fitted with a fastener 25 at its end. Furthermore, a set of tie rods 24 is set at certain intervals along the length of the UHPC formwork beam 2, and the tie rods 24 penetrate the side wall of the UHPC formwork beam 2. The bottom extension section is embedded in the lightweight partition board for a certain length to counteract the lateral pressure during concrete pouring and control the deformation of the formwork.

[0019] Please see Figure 4 In one embodiment, preferably, there are two sets of connectors 4 on the UHPC mold shell 3. The two sets of connectors 4 are respectively located on both sides of the UHPC mold shell 3, and each set of connectors 4 consists of two connectors 4. Furthermore, the connectors 4 are respectively located on both sides of the UHPC mold shell 3 to facilitate the hoisting and lifting of the lifting hooks during the hoisting and lifting stage of the overall installation structure of the partition wall panel 1.

[0020] The working principle and usage process of this utility model are as follows: First, the UHPC formwork beam 2, partition wall panel 1, and UHPC formwork 3 are prefabricated in the factory and transported to the site; then, multiple partition wall panels are assembled, and their bottoms are interlocked with the inside of the UHPC formwork 3 using mortise and tenon joints; next, the tenons 11 at the top of multiple partition wall panels 1 are inserted into the mortise grooves 21 of the UHPC formwork beam 2; then, multiple connectors 4 are inserted into the inside of the partition wall panel 1 through the UHPC formwork beam 2 and the UHPC formwork 3 respectively, thus assembling them into an integral unit; next, the hooks of the hoisting equipment are used to attach the connectors 4 on both sides of the UHPC formwork 3, hoisting it to the designated position and fixing it, and then the precast steel cage 23 is placed in the placement groove 22; the tie rods 24 are tensioned in stages; finally, concrete is pumped and poured in layers, and simultaneously vibrated to compact it, completing the overall installation of the UHPC formwork beam-lightweight partition wall.
