Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a single-side formwork construction of an exterior wall tripod. Background Art
[0002] External wall tripod single-sided formwork construction is a technology used for external wall construction in construction projects. This construction method is usually used for basement external wall construction. Due to the influence of surrounding buildings and structures, the site often appears relatively cramped. In order to maximize the use of land resources, a single-sided formwork solution has to be adopted.
[0003] A search revealed a Chinese patent application with publication number CN111173264A, which discloses a single-sided formwork construction device and method for a basement exterior wall. The device comprises a pre-embedded steel plate embedded in the basement foundation slab and a set of anchor bars pre-implanted into the basement sidewall. A formwork is arranged on one side of the basement sidewall, with a set of wooden planks arranged vertically outside the formwork. A set of double-row steel pipes is arranged horizontally on the wooden planks. A set of vertical bars is welded to the pre-embedded steel plate, and the vertical bars and anchor bars are secured with wire ties. The outer end of the anchor bar is welded to one end of a waterstop screw, the other end of which passes through the formwork and extends from between the double-row steel pipes. The extended end of the waterstop screw is secured with a nut fastener. This invention utilizes single-sided formwork to achieve efficient construction and quality control of the basement exterior wall within the narrow basement sidewall area, resolving the problems of insufficient space, long construction period, and construction difficulty associated with traditional double-sided formwork.
[0004] Based on the above search and combined with existing technology findings;
[0005] Although the above-mentioned search patent uses waterstop bolts to prevent leakage, most of the existing tripod formwork is difficult to match the floor height and requires secondary exterior wall support. The secondary support often uses tension screws and installs multiple waterstop plates, which reduces economic benefits and increases the risk of leakage. Therefore, there are certain limitations. Utility Model Content
[0006] In order to solve the above technical problems, the utility model proposes a single-side formwork construction of an exterior wall tripod, which has good economic benefits and plays an anti-leakage role.
[0007] The technical solution to achieve the purpose of the utility model is: a single-sided formwork construction of an exterior wall tripod, including a wall and a main beam, a tripod is fixedly installed on one side of the wall, a tongue and groove is opened on the top of the wall, and a hanging formwork is provided on the outside of the tongue and groove.
[0008] Preferably, a floor slab is cast together on the top of the wall and the main beam, and a water stop plate is provided between the wall and the floor slab.
[0009] Preferably, a plurality of longitudinal beam reinforcements are fixedly installed between one side of the main beam and the wall, and a connector is provided at one end of each longitudinal beam reinforcement.
[0010] Compared with the prior art, the present invention has the following significant advantages:
[0011] Firstly, the utility model is cast in one step, which reduces the amount of water-stop steel plates used, enhances economic benefits, saves raw materials and reduces leakage at construction joints.
[0012] Second, the utility model installs longitudinal reinforcement between the main beam and the wall, which improves the overall firmness and stability of the building, is conducive to improving the bearing capacity of the building, and is safer.
[0013] It solves the problem that most of the existing tripod formwork is difficult to match the floor height and requires secondary exterior wall formwork. The secondary formwork often uses tension screws and installs multiple water stop plates, which reduces economic benefits and increases the risk of leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following is a detailed description of the present invention, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] The utility model provides a single-side formwork construction of an exterior wall tripod through improvement. The technical solution of the utility model is:
[0022] like Figure 1-Figure 3The single-sided formwork construction of the exterior wall tripod shown includes a wall 1 and a main beam 6. A tripod 2 is fixedly installed on one side of the wall 1. A tongue and groove 3 is opened on the top of the wall 1. A hanging formwork 4 is set on the outside of the tongue and groove 3. The use of the tripod 2 for single-sided formwork can effectively reduce the risk of leakage caused by screw reinforcement.
[0023] Furthermore, a floor slab 5 is cast together on the top of the wall 1 and the main beam 6, and a water stop plate 7 is arranged between the wall 1 and the floor slab 5, thereby reducing the number of construction joints and water stop plates 7, thereby reducing the risk of external wall leakage while ensuring economic benefits.
[0024] Furthermore, a plurality of longitudinal beam reinforcements 8 are fixedly installed between one side of the main beam 6 and the wall 1. A connector 9 is provided at one end of each longitudinal beam reinforcement 8. The longitudinal beam reinforcements 8 are utilized to increase strength and rigidity, improve deformation capacity, control crack width, and increase durability.
[0025] The specific working method is: fix the longitudinal reinforcement 8 at the position of the main beam 6 in the wall 1 and reserve the connector 9. After the main and secondary beams of the wall 1 formwork are installed, use the tripod 2 to reinforce the single-side formwork, and the reinforcement height of the top of the tripod 2 is not lower than the bottom elevation of the upper floor slab 5; set the tongue and groove 3 at the top of the wall 1, and set the water stop plate 7 on the upper part of the tongue and groove 3. The height of the tongue and groove 3 is the height of the anti-slope of the outer wall of the upper floor slab 5; pour the concrete of the wall 1 to the top of the tongue and groove 3; and then pour half of the tongue and groove 3 together with the floor slab 5.
[0026] The technical means disclosed in the present invention are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacements of the above technical features. Matters not covered in the present invention belong to the common knowledge of those skilled in the art.
