Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to an assembled external wall single-side formwork connection tool and a construction method. Background Art

[0002] Before assembling the exterior wall, formwork support is required. Since double-sided formwork cannot be used, single-sided formwork technology is often used. The traditional single-sided formwork process uses steel pipes to build a frame as the support system for the formwork. This process has the disadvantages of using a large number of steel pipes, a long erection period, and a low one-time formwork height. The construction plan for single-sided formwork support can be roughly divided into the following plans: 1. Use steel to make triangular trusses and embedded parts as the support system, but the triangular trusses are heavy, expensive, and have low work efficiency. 2. Use a support system that welds positioning bolts on retaining piles and retaining walls, but the positioning bolts need to pass through the waterproof layer of the exterior wall, and the waterproof layer needs special reinforcement measures, which increases the construction cost. 3. Use a support system with steel pipe fasteners and diagonal braces, but there are many support nodes, all fasteners are connected, and it is easy to expand the formwork, and they need to be removed one by one.

[0003] This case was created to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0024] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0025] See attached Figure 1-2 As shown, a prefabricated exterior wall single-side formwork connection tool includes a support 1, a through accommodating groove 2 is opened on the relative rear side of the support 1, and a connecting component 3 is arranged on the relative front side of the support 1, and a supporting rod is connected between the prefabricated exterior wall.

[0026] The connecting assembly 3 is connected to the support 1 in an overall horizontal sliding manner. The connecting assembly 3 includes a sliding seat 9, which is vertically connected to a support rod 6. A bearing sleeve 5 and a connecting sleeve 7 are inserted into the support rod 6 at intervals, and the bearing sleeve 5 and the connecting sleeve 7, and the connecting sleeve 7 and the sliding seat 9 are connected by a spring 8. The lateral sides of the connecting sleeve 7 are respectively hinged with a rotating rod 11, and the outer end of the rotating rod 11 is hinged with a stop block 12.

[0027] Under normal conditions, the stop block 12 has a certain gap with the inner wall of the support 1. After the connecting sleeve 7 is subjected to the transmitted force, it is pressed downward to drive the stop block 12 to press against the inner wall of the support 1 outward. At the same time, the connecting component 3 slides backward as a whole to the maximum displacement position (against the cast stone 15 and is horizontally supported).

[0028] In order to prevent the stopper 12 from being out of position during the force movement process, causing the support rod 6 to deflect or tip over, this solution is provided with a sleeve 13 placed on the support 1, and the stopper 12 is placed in the sleeve 13, so that the movement trajectory of the stopper 12 is limited by the sleeve 13. Secondly, limiting blocks 14 are provided on both sides of the sliding seat 9, which are slightly higher than the stopper 12 and the positive projection completely covers the stopper 12, so that the stopper 12 can always slide horizontally. The setting of the stopper 12 allows the support rod 6 to be dispersed laterally when subjected to an irregular direction of external force, and can prevent the support rod 6 from tipping over during the movement process.

[0029] The setting of the spring 8 can intuitively judge the magnitude of the external force causing the outer wall to collapse through the degree of compression thereof.

[0030] It should be noted that concrete blocks 15 need to be poured at approximately predetermined positions against the wall, and the support rods 6 are placed against the concrete blocks 15 by means of the bearing sleeves 5 and the connecting sleeves 7 .

[0031] In this scheme, the concrete stone 15 only needs to be raised when casting, and there is no need to set it to a standard size or regular shape (similar to a square). The project volume is small and the operation is convenient. The concrete stone 15 only needs to be smaller than the receiving groove 2 opened on the support 1, avoiding the specification size being too cumbersome, and it can be directly knocked off later. It is more convenient to use and has a greater force support strength. At the same time, it is more convenient to disassemble the connection tool after the external force is removed.

[0032] See attached Figure 3-4 As shown, further, in order to limit the position of the support 1 relative to the concrete stone 15, a screw is connected to the rear side of the support 1 with a diagonal thread, and a clamping block 16 is connected to the inner side of the screw. An L-shaped opening is provided inside the clamping block 16 so as to apply pressure to the concrete stone 15 in both the X and Y axis directions. At the same time, a layer of soft pad is provided inside the L-shaped opening to cope with the uneven shape of the concrete stone 15.

[0033] The supporting rod is hinged to the front end of the connecting assembly 3 and arranged obliquely to compensate for the height limitation of the support 1. The supporting rod includes a main rod 4, the axial interval of the main rod 4 is connected to the secondary rod 10, the main rod 4 and the secondary rod 10 are connected by a screw sleeve 18, and the screw sleeve 18 is rotated to realize the movement towards or in the opposite direction. The outer end of the secondary rod 10 is provided with a connecting block 17 for connecting the assembled external wall, and the outer end of the main rod 4 is hinged to the connecting assembly 3.

[0034] The construction method of the connection tool of this scheme is to first cast concrete stones 15 at intervals at predetermined positions against the wall (or use protrusions at similar positions), put the supports 1 on the corresponding concrete stones 15 one by one, and turn the screw to tighten the block 16 to the concrete stone 15 until the support 1 is stable; at this time, after the supporting rod is assembled, its lower end is hinged on both sides of the bearing sleeve 5, and the length is adjusted to be uniformly flush for support; after completion, the screw is turned in the opposite direction until the block 16 loosens the concrete stone 15, and the entire assembly can be disassembled, and the concrete stone 15 can be knocked out.

[0035] The above construction is mainly used for formwork support on relatively flat ground, and can also be applied to pits or places with protruding stones 15 for direct use.

[0036] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
