Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a drawer-type internal angle chamfering forming template and a construction method thereof. Background Art

[0002] At present, the place with the greatest risk of roof leakage is the inner corner of the protruding roof structure, which is prone to water accumulation and leakage. In order to improve the waterproof performance of the roof, it is necessary to solve the hidden danger of water leakage in the inner corner. The most effective way is to set a large inner corner footing. The larger the size of the large footing, the better the waterproof effect. The traditional construction method uses layer-by-layer pouring or formwork pouring. This construction method cannot guarantee that the chamfered slope shape is formed in one time, nor can it guarantee a good result in one time. It often requires multiple pourings and the size of each pouring will have deviations. Summary of the invention

[0003] In order to solve the above problems, the present invention discloses a drawer-type internal angle chamfering forming template and a construction method thereof.

[0004] The specific plan is as follows: A drawer-type internal angle chamfering forming template is installed at the internal angle of the roof, including a drawer-type structure, the drawer-type structure including a supporting bottom plate and a sliding plate, the supporting bottom plate is a three-section folding plate, consisting of an upper, middle and lower section, wherein the upper end of the upper section is inclined to the right, the upper end of the middle section is inclined to the left, and the lower section is horizontally arranged, the sliding plate is placed on the surface of the middle section and can slide along its inclined direction, and a sliding hole for the sliding plate to pass through is provided between the upper section and the middle section of the supporting bottom plate.

[0005] Furthermore, a hinged protrusion with a hole is provided in the middle of the surface of the middle section of the supporting bottom plate, and a flap is hingedly connected thereto, and one end of the flap is hingedly connected to the hole of the hinged protrusion.

[0006] Furthermore, the lower section of the supporting base plate is fixed on the inner angle plane of the roof by ground nails.

[0007] Furthermore, the sliding plate is an L-shaped plate, the lower end of which is bent upward.

[0008] A construction method for a drawer-type internal angle chamfering forming template comprises the following steps: S1. Install the drawer-type structure at the inner corner, and fix the lower section of the supporting bottom plate to the inner corner plane of the roof through ground nails. At this time, the lower end of the sliding plate abuts against the hinged protrusion, and the flap is placed under the hinged protrusion; S2. Pour chamfering material between the upper end of the drawer-type structure and the inner corner of the roof until it is flush with the upper end of the supporting bottom plate; S3, push the sliding plate upward until it contacts the vertical surface of the inner corner of the roof, and flip the flap upward so that the end of the flap abuts against the lower end of the sliding plate; S4. After the chamfering is formed, the overall drawer-type structure is directly removed.

[0009] The beneficial effects of the present invention are as follows: the chamfered structure at the internal corner can be quickly formed through the drawer-type structure, and the chamfered top can be cast to the top once to form the shape, the size and quality can be guaranteed, and the construction quality can be effectively ensured; the overall structure is ingenious and simple, the installation speed is fast, and the assembled installation can be realized; it can be prefabricated in the factory and mass processed, and has broad market prospects.

[0015] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0016] like Figure 1 As shown, the present invention provides a drawer-type internal corner chamfering forming template, which is installed at the internal corner of the roof, including a drawer-type structure, the drawer-type structure including a supporting base plate (1) and a sliding plate (5), the supporting base plate (1) is a three-section folding plate, consisting of three sections: upper, middle and lower, wherein the upper end of the upper section is inclined to the right, the upper end of the middle section is inclined to the left, and the lower section is horizontally arranged, the sliding plate (5) is placed on the surface of the middle section and can slide along the inclined direction, and a sliding hole for the sliding plate (5) to pass through is provided between the upper section and the middle section of the supporting base plate (1). During casting, the drawer device of the device of the present invention can quickly form a slope shape on the top, can isolate and separate the upper casting material from the large footing slope, and can quickly form a large footing structure. In this embodiment, a hinged protrusion (3) with a hole is provided in the middle of the surface of the middle section of the supporting base plate (1), and a flap (4) is hingedly connected thereto, and one end of the flap (4) is hingedly connected to the hole of the hinged protrusion (3).
