Embodiment 1

[0021] This embodiment is applied to the occasion of butt jointing of building formwork, the length of the building formwork used is 1800mm, the thickness is 10mm, and the expansion joints reserved between the building formworks are 2mm-3mm wide. The expansion joints of this structure are butt joints, and the cross-section is selected as figure 1 The I-shaped caulking strip shown is 1800mm long, 18mm wide on the horizontal side, 1.5mm thick in the middle of the cross-section of the horizontal side 1, and 10mm high on the vertical side 2. When the building formwork on one side is paved in place, then the open angular groove on one side of the caulking strip is matched with the already in place building formwork, and the opening angular groove on the other side of the caulking strip is inserted into the building formwork to be paved later. A seamless joint is formed between adjacent building formwork. In this embodiment, the width of the horizontal side 1 is much larger than th...

Embodiment 2

[0023] This embodiment is a cross section such as figure 2 The application of the T-shaped sealing strip shown is the same as that in embodiment 1, except that the joint filling strip is inserted into the reserved expansion joint after the adjacent templates are paved together. In this embodiment, the paved building formwork is 1800mm long and 18mm thick, with expansion joints of 2mm to 3mm reserved, and the matching caulking strips are cut according to 1800mm. , the height of the vertical side 2 is 18mm. The caulk ratio for this structure figure 1 The caulking strip with I-shaped cross-section shown is more convenient to install and has a similar leak-proof effect. The disadvantage is that it is easy to move longitudinally, but it does not affect the sealing.

Embodiment 3

[0025] This embodiment is a cross section such as image 3 For the 匚-shaped caulking strip shown, the caulking strip of this structure is set on the outer edge of the initial or last building formwork. image 3 The caulk shown is figure 1 The cross-section shown is a deformed body of the I-shaped caulking strip, and the upper and lower horizontal sides 1 on one side of the vertical side 2 are removed, and the rest is a U-shaped caulking strip. The structural caulking strip is set on the edge of the matching building formwork, and the gap can be eliminated by adjusting the matching position. The transverse edge 1 in this embodiment is 7mm wide, and all the other dimensions are the same as Embodiment 1, and the actual use effect is also similar.

Abstract

The invention discloses a building formwork joint filling bar. According to the building formwork joint filling bar, equal-length transverse sides and equal-length vertical sides made of same material sequentially form a long-bar component with a right-angle-shaped groove. The cross section of each transverse side is in the shape of an arch, the outward face is an a circular arc camber, and the face matched with a building formwork is a plane; each vertical side is a equal-thickness thin plate, the vertical sides are perpendicularly connected with the transverse sides to form the joint filling bar with the I-shaped, T-shaped, rightward-U-shaped, L-shaped or h-shaped cross section, the width of each transverse side is 7-20mm, the thickness of the middle of each circular arc camber is 1-2mm, the thickness of each vertical side is 0.6-1.5mm, and the height of each vertical side is 10-18mm. According to the building formwork joint filling bar, the width of each transverse side is far larger than that of a telescopic joint reserved when the building formwork is laid, shielding is tight, anti-leakage effect is good, flow-side residue is avoided in the formwork detaching process after the pouring, manual chiseling is avoided, and the pouring quality and the construction progress are also greatly improved. The building formwork joint filling bar is simple in structure, easy to manufacture, low in matching cost and suitable for being matched with various formworks.

Description

technical field [0001] The invention relates to a construction equipment, in particular to a caulking strip, which is plugged into expansion joints reserved during building formwork paving, so as to avoid grout leakage during pouring and improve construction quality. Background technique [0002] Concrete pouring is the main construction task in construction engineering. Before pouring, the formwork needs to be paved according to the engineering design. The quality of formwork paving directly affects the construction quality. In today's era, the materials of formwork used in construction projects mainly include wood, bamboo and plastic. In actual use, no matter what kind of material the formwork is made of, there will be a certain amount of deformation. For example, under normal temperature and humidity conditions, the shape of wooden and bamboo formwork is almost unchanged, keeping the surface of the board flat. If it is in a humid environment, it will bulge and deform. T...
