[0026] Since the L-shaped mold plate can be removed from the front and rear sides of the pool wall respectively, it is not necessary to pull out the deformation joint during the removal, so it is suitable for the pouring construction of narrow deformation joints, and the L-shaped mold plate needs to be used in combination for the pouring construction of the deformation joint.

[0027] Since the pool wall height is high, the overall strength of the L-shaped mold plate is considered, the height of each L-shaped mold plate is not greater than 1500 mm, under this length, the L-shaped mold plate has good strength and is very convenient for processing and construction, in order to realize the design in the height direction, the L-shaped mold plate is designed into multiple groups, and each group of L-shaped mold plates is arranged along the deformation joint height direction in sequence, so that the requirement of the pool wall deformation joint height is met.

[0028] In order to realize the support of the inner wall of the deformation joint, each group of L-shaped templates is divided into four L-shaped templates which are closely attached to the pool wall, two of which are fixed on the pouring formwork 7 on the left side of the deformation joint, one on the inner wall of the pool wall and one on the outer wall of the pool wall, and the other two are fixed on the pouring formwork 7 on the right side of the deformation joint, also one on the inner wall and one on the outer wall of the pool wall. The combination of the four L-shaped templates realizes the support of the entire inner wall of the deformation joint.

[0029] In view of the installation problem of the L-shaped template on the pouring formwork 7, the two L-shaped templates on the same side are connected by positioning the pull wire rod 5, and the L-shaped template can be fixed on the pouring formwork 7 on the front and rear sides by using the original pull wire rod 5 on the pouring formwork 7, realizing the installation and positioning of the two L-shaped templates.

[0030] A water stop 6 is vertically arranged in the deformation joint, which is poured into the pool wall on both sides. The water stop 6 is an important component for preventing water leakage in the deformation joint. In order to facilitate the installation of the water stop 6, the width of the end form 2 is half of the thickness of the pool wall, and a 10mm gap is left between the inner and outer end forms 2 for the water stop 6. After the installation of the four L-shaped templates, the installation gap of the water stop 6 can be left.

[0031] There are multiple long oval bolt holes 4, which are sequentially and spaced apart along the height direction of the side form 1. The specific number is matched with the pull rod insertion hole on the pouring formwork 7.

[0032] As a preferred scheme, the long oval bolt hole 4 is 150mm long, the center distance between the long oval bolt holes 4 is 500mm, and the plate thickness of the side form 1 and the end form 2 is 3mm. At this time, it can adapt to most construction requirements, and the specific parameters can be adjusted according to the specific situation.

[0033] A pouring construction method for a narrow deformation joint of a large pool wall, the method steps are as follows:

[0034] Step one, using pouring formwork 7 to pour the pool wall, the pouring formwork 7 is a double-layer formwork structure composed of inner formwork 71 and outer formwork 72;

[0035] Step two, design L-shaped template as side formwork,

[0036] The L-shaped template is assembled by welding two parts of the side mold 1 and the end mold 2 to form a 1500mm high L-shaped template. When welding, the side mold 1 and the end mold 2 are fully welded to form an L-shaped steel template, and then a (5*5) angle steel strip 3 is used to strengthen the welding of the side mold 1 and the end mold 2. The side mold 1 has an elliptical bolt hole 4 with a length of 150mm, which can be applied to pool walls with different heights;

[0037] The side mold 1 and the end mold 2 are made of 3mm steel plates, the length of the side mold 1 is 300mm, and the length of the end mold 2 is (pool wall thickness / 2-5mm);

[0038] Step three, use the tower crane to transport the pouring mold 7 and the L-shaped template to the construction site for installation;

[0039] Step four, before pouring the pool wall deformation joint, first install the pouring mold 7 on the left and right sides of the deformation joint, and leave a 3cm deformation joint between the left and right pouring molds 7, then install four L-shaped templates in the deformation joint, and the four L-shaped templates are respectively installed on the four edges of the deformation joint and are fixedly connected with the pouring mold 7. The pouring mold 7 is provided with a pulling rod insertion hole, and the long elliptical bolt hole 4 of the side mold 1 is correspondingly provided with a pulling rod insertion hole. The pulling rod 5 passes through the pulling rod insertion hole and the long elliptical bolt hole 4 to position the pouring mold 7 on the front and back sides of the pool wall and the L-shaped template;

[0040] When installing the L-shaped template, the side mold 1 of the L-shaped template is located between the inner mold 71 and the outer mold 72 of the pouring mold 7, the long elliptical bolt hole 4 is coincided with the pulling rod insertion hole, the end mold 2 is tightly arranged on the inner wall of the deformation joint, and the installation gap of the water stop belt 6 is left between the two end molds 2 on the same side. Before installation, the surface of the L-shaped template is coated with an interface agent to facilitate demolding;

[0041] Step five, install the water stop belt 6 between the left and right pool walls of the deformation joint, and the water stop belt 6 is inserted into the water belt installation gap clamped between the four L-shaped templates;

[0042] Step six, the left and right pool walls of the deformation joint are poured at the same time;

[0043] Step seven, after pouring, remove the pouring mold 7 and the L-shaped template;

[0044] Step eight, pour the deformation joint to complete the pouring construction.

[0045] As a preferred solution, a self-locking nut is added to the pulling rod 5 to enhance the stability of the L-shaped template.

[0046] In the traditional pool wall construction, when the side formwork 1 cannot be supported, the pool wall on one side has to be constructed first, and then the filling material is used as a formwork to construct the pool wall on the other side. The utility model realizes the support of the side formwork 1 in the narrow deformation through the combination of the L-shaped formwork. After the support, the L-shaped formwork can be taken out by lightly knocking, which is very convenient and is not affected by the deformation joint.
